A method for designing a left and right side body common molding process of a vehicle according to an embodiment of the present invention will be described with reference to fig. 1 to 7.
According to the design method of the common mode process of the left side wall and the right side wall of the vehicle, the side wall 100 of the vehicle comprises a left side wall 1 and a right side wall 2, each side wall 100 is provided with a door opening 10, each side wall 100 is provided with an inner side surface and an outer side surface, and each side wall 100 is provided with a vehicle head end 20 and a vehicle tail end 30.
As shown in fig. 1, a side panel 100 of a vehicle has a left side panel 1 and a right side panel 2, and the left and right side panels 2 are both provided with door openings 10, so that a vehicle door structure can be installed, where an inner side surface of the side panel 100 is a surface facing the inside of the vehicle, and an outer side surface of the side panel 100 is a surface facing the outside of the vehicle.
Each side coaming 100 completes the stamping process through multiple stamping steps, and stamping dies adopted in the multiple stamping steps of each side coaming 100 are different, that is, as shown in fig. 1 and fig. 2, when the stamping process of the stamping step is performed on the side coaming 100, the side coaming 100 can be further processed every time stamping is performed, that is, as shown in fig. 1, the side coaming 100 is formed into a schematic diagram of the final shape of the side coaming 100 after the multiple stamping steps are performed on the left and right coamings 2.
As shown in fig. 1 and fig. 2, the left side panel 1 and the right side panel 2 are symmetrical in shape, and the left side panel 1 and the right side panel 2 at least adopt a set of common mode dies 200 in one of the stamping steps, that is, in the stamping steps of the left side panel 2 and the right side panel 2, each step requires a set of dies to perform stamping processing, and in the stamping steps of the left side panel 1 and the right side panel 2, a plurality of sets of dies are required, so that at least one step in the stamping steps, the left side panel 1 and the right side panel 2 are processed by using the same set of dies, the number of dies required by the stamping steps of the side panels 100 can be effectively reduced, the cost of the dies can be effectively reduced, and the number of dies can be reduced, and the storage space occupation of the dies can also be saved.
Specifically, the design of the common mode mold 200 includes the following steps:
the left side coaming 1 and the right side coaming 2 are arranged in the same model space in a simulation model mode, the inner side faces of the two side coamings 100 are the same, the outer side faces of the two side coamings 100 are the same, and the simulation models of the two side coamings 100 are overlapped to form an overlapping area.
As shown in fig. 3 and 4, the left coaming 1 and the right coaming 2 are stacked together, so that the stacked positions of the left coaming 1 and the right coaming 2 form an overlapping area, and the orientations of the left coaming 1 and the right coaming 2 are placed towards the same side, i.e. the inner side of the left coaming 1 faces a first direction, then the right coaming 2 can be stacked and placed above the left coaming 1, and the inner side of the right coaming 2 is also placed towards the first direction.
Accordingly, if the inner side of the left side panel 1 is placed toward the second direction, the right side panel 2 is placed above the left side panel 1 in a stacked manner, and the inner side thereof is also placed toward the second direction.
The first direction may be a direction toward the support surface after the left side board 1 and the right side board 2 are placed. Accordingly, it will be appreciated that the second direction may be a direction away from the resting support surface after the left and right side enclosures 1, 2 are placed.
It can be understood that the inner side of the left coaming 1 and the inner side of the right coaming 2 are placed in the same direction, and the outer side of the left coaming 1 and the outer side of the right coaming 2 are also placed in the same direction.
In the embodiment in which the left shroud 1 and the right shroud 2 are placed in the same space, the left shroud 1 may be located below and the right shroud 2 may be located above. The left coaming 1 may be above and the right coaming 2 below.
As shown in fig. 3 and 4, the head ends 20 of the side enclosures 100 are located within the overlap region, at least a portion of the door opening 10 is located within the overlap region, and the tail ends 30 of the side enclosures 100 are located outside the overlap region. The head ends 20 of the two side coamings 100 are oppositely arranged, and when the left coamings 1 and the right coamings 2 are arranged in an overlapping mode, at least partial areas of the door openings 10 of the left coamings 1 are overlapped with at least partial areas of the door openings 10 of the right coamings 2, so that after the other side coamings 100 are arranged in an overlapping mode, the overlapped areas have overlapped hollowed-out areas. Therefore, when the two side coamings 100 are subjected to stamping operation subsequently, the two side coamings 100 are fixed by arranging the external structure through at least a part of the overlapping area of the door opening 10, and when the common mode die 200 is manufactured, the positions of the two side coamings are fixed, so that errors of the manufacturing size of the common mode die 200 caused by the sliding of the two side coamings 100 are avoided.
As shown in fig. 3 and 4, the two side panels 100 select a molding surface located outside the overlapping area from the molding surfaces to be punched in the whole punching process, and at least a part of the molding surfaces outside the overlapping area is disposed on the common mold 200.
In other words, when the left side panel 1 and the right side panel 2 are stamped, the same set of common mold 200 is used, that is, a structure capable of stamping the left side panel 1 and the right side panel 2 needs to be provided on the common mold 200. Therefore, in manufacturing the common mold 200, when the regions outside the overlapping region of the two left and right side fences 1 and 2 placed one on top of the other are to be pressed, it is necessary to provide the corresponding positions on the common mold 200 with the structures to be used for the pressing of the left and right side fences 1 and 2, respectively.
Thus, when the left side panel 1 and the right side panel 2 are press-worked by using the common die 200, even if the regions are located outside the overlapping region of the two side panels 100, the press-working can be realized by the press-working structures for the left side panel 1 and the right side panel 2 provided in the common die 200.
According to the design method of the common mode process of the left side wall and the right side wall of the vehicle, the simulation model of the left side wall 1 and the simulation model of the right side wall 2 are overlapped and placed in the same model space, the common mode die 200 capable of simultaneously processing the left side wall 1 and the right side wall 2 is manufactured, and then the stamping processing of the left side wall 1 and the right side wall 2 can be realized through the common mode die 200, so that the number of dies in the stamping processing process of the left side wall 1 and the right side wall 2 is effectively reduced, the cost of the dies is reduced, and the space occupation of the dies is also reduced.
Further, the design of the common mode mold 200 further comprises the steps of: the two side enclosing plates 100 select punched holes outside the overlapping area from punched holes to be processed in the whole stamping process, and the punching cutter 40 corresponding to at least part of the punched holes outside the overlapping area is arranged on the common mode die 200.
Specifically, two side panels 100 are placed in an overlapping manner, the overlapping portion between the two side panels 100 is an overlapping area, and in an area outside the overlapping area after the two side panels 100 are overlapped, punched holes needing to be punched can be arranged on both the left side panel 1 and the right side panel 2, therefore, on the common mode die 200, for the punched holes of the area outside the overlapping area of the left side panel 1, the punching tool 40 is arranged at the corresponding position of the common mode die 200, so that when the common mode die 200 is used for punching the left side panel 1, the punching step can be effectively carried out on the area outside the overlapping area of the left side panel 1.
Accordingly, in the common mode die 200, the punching tool 40 is provided at the corresponding position of the common mode die 200 for punching the right side panel 2 in the region outside the overlapping region, so that the punching step can be effectively performed on the region outside the overlapping region of the right side panel 2 when the common mode die 200 is used for punching the right side panel 2.
Thereby can make common mode mould 200 when carrying out stamping process to left coaming 1 or right coaming 2, can guarantee to once accomplish the punching press operation of left coaming 1 or right coaming 2, need not to punch a hole the operation respectively once more to the region outside the overlap region of two side coamings 100 after the punching press, promote work efficiency.
As shown in fig. 3 and 4, the left and right side fences 1 and 2 overlap each other at a partial parting surface in the overlap region, and a press-worked surface corresponding to the overlapping parting surface in the overlap region is provided on the common die 200 or a press die in another press step.
Specifically, when the left side coaming 1 and the right side coaming 2 are placed in an overlapping manner, the head ends 20 of the two side coamings 100 are opposite, and at least part of profiles of the two side coamings 100 are overlapped in the overlapping region, so that the stamping surface of the profile in the overlapping region on the two side coamings 100 can be arranged on the common mode die 200, and the stamping surface in the overlapping region on the left side coaming 1 can be stamped through the common mode die 200. Meanwhile, the common mode die 200 may also perform press working on the press working surface of the right side panel 2 in the overlapping area.
In addition, for the processing of the profiles in the overlapping region on the left side enclosing plate 1 and the right side enclosing plate 2, the corresponding die can be used for stamping the left side enclosing plate 1 or the right side enclosing plate 2 by arranging the corresponding stamping faces on the dies for respectively stamping the left side enclosing plate 1 and the right side enclosing plate 2 in other stamping steps.
For example, when a die surface in an overlapping region of the left side panel 1 is pressed, the pressing surface of the common die 200 that is pressed against the overlapping region of the left side panel 1 and the right side panel 2 may be used to perform the pressing. In other steps of stamping, a corresponding stamping surface is arranged on a die for stamping the left side enclosing plate 1, so that the molded surface of the overlapping area of the left side enclosing plate 1 can be processed.
Accordingly, when the molding surface of the right side panel 2 in the overlapping region is subjected to stamping, the stamping surface of the common mode die 200, which is subjected to stamping for the overlapping region of the left side panel 1 and the right side panel 2, can be used for stamping. In other steps of stamping, a corresponding stamping surface is arranged on a die for stamping the right side enclosing plate 2, so that the molding surface of the overlapping area of the right side enclosing plate 2 can be processed.
Further, a punching tool 40 is provided on the common mold 200 for punching at least a portion of the overlapping profiles in the overlapping area. Therefore, the punching tool 40 which is arranged on the common mode die 200 and corresponds to at least part of the overlapped molded surfaces of the two side enclosing plates 100 can be used for punching the two side enclosing plates 100, and the working efficiency is improved.
The common mold 200 is provided with the cam mechanism 50, and the cam mechanism 50 is disposed corresponding to the overlapping area of the door opening 10 on the two side panels 100. The cam mechanism 50 is a mechanical mechanism that changes vertical motion into horizontal motion or tilting motion by using a cam and a slider in cooperation. The vertical force of the machine tool is changed into the oblique force.

The cam mechanism 50 described herein is a mechanical structure that is available in the prior art and will be understood by those skilled in the art and will not be described in detail herein.
As shown in fig. 3 and 4, the left and right fences 1 and 2 have front-rear direction median lines, respectively, and the overlapping regions have lines of symmetry, the front-rear direction median lines being arranged in parallel with the lines of symmetry.
Specifically, a straight line, such as the line L1 in fig. 3 and 4, is provided between the two side panels 100, i.e., a symmetry line, and the symmetry line is located at the center of the two side panels 100, so that it can be seen that the two side panels 100 placed in a stacked manner are symmetrically placed. On each side panel 100, a neutral line is provided, the neutral line of the left side panel 1 being indicated by line L2 in fig. 3 and 4, and the neutral line of the right side panel 2 being indicated by line L3 in fig. 3 and 4.
Further, the longitudinal centerline is spaced apart from the symmetry line by a predetermined distance, and the symmetry line on each side panel 100 is located on the side of the longitudinal centerline adjacent to the vehicle head end 20.
As shown in fig. 3 and 4, the centerline is provided on both the left panel 1 and the right panel 2, and a certain distance interval is provided between the centerline on the left panel 1 and the symmetry line, and a certain distance interval is also provided between the centerline on the right panel 2 and the symmetry line. Therefore, the operation parameters of the automatic manipulator can be met when the left coaming 1 and the right coaming 2 are machined.

Thus, the present invention utilizes automated robot parameters to stack the left and right coamings 1 and 2 such that both L2 and L3 are 150mm from line L1, which is the set distance as described above.
As shown in fig. 3 and 4, the area of the overlap region occupies at least half of the area of a single side panel 100. Therefore, after the left side coaming 1 and the right side coaming 2 are stacked and placed, the area of the overlapped molded surface occupies more than half of the area of each coaming, and stable placement between the left side coaming 1 and the right side coaming 2 can be further guaranteed.
