Description

Die capable of eliminating wrinkling caused by continuous right-angle bending of periphery of part

Technical Field

The utility model relates to the technical field of thin-wall stamping part processing dies, in particular to a die capable of eliminating the wrinkling caused by the continuous right-angle flanging of the periphery of a part.

Background

As shown in figure 1, the thin-wall stamping part is a thin-wall stamping part, an existing processing die is shown in figure 2 and comprises a male die 1 and a female die 2, a forming hole 5 is formed in the middle of the female die 2, the depth of the forming hole 5 is the same as the thickness of the part, a part material 3 is placed on the female die 2 during stamping, the male die 1 is extruded by a hydraulic press, the part material 3 is subjected to stamping forming, and then the part forming process is completed through the processes of manual shape correction, edge shearing and the like.

SUMMERY OF THE UTILITY MODEL

The utility model aims to provide a die capable of eliminating the wrinkling of the part periphery caused by the continuous right-angle flanging.

The technical purpose of the utility model is realized by the following technical scheme:

the utility model provides a can eliminate peripheral right angle of part mould that corrugates that takes shape in succession, includes terrace die and die, be equipped with the shaping hole on the die, the through-hole is set to the shaping hole, the upper end in shaping hole is equipped with the step hole, the shape in step hole is the same with the shape after the part expandes, sets up step pore structure, and it is accurate to fix a position before can making the part material punching press, reduces subsequent deburring work, sets the through-hole into with the shaping hole simultaneously, makes things convenient for subsequent drawing of patterns.

Furthermore, the thickness of the female die is 20-30 mm greater than the sum of the height of the part edge and the depth of the step hole.

Furthermore, the depth of the stepped hole is not less than the thickness of the part material, so that the part material cannot run and move during stamping.

Furthermore, the punching end of terrace die is equipped with the radius angle, the both ends in shaping hole also are equipped with the radius angle, through the both ends radius angle at terrace die and shaping hole, when can avoiding the punching press, produce the local too big shearing force that produces in part material surface, form the indentation.

In conclusion, the utility model has the following beneficial effects: by improving the structure of the die, the utility model has the advantages of convenient processing, accurate positioning of stamping raw materials, good surface quality of parts and the like, effectively eliminates wrinkles generated in the forming process of the raw materials, improves the surface quality of the surfaces of the parts, is more convenient to demould and reduces the subsequent trimming work.

Detailed Description

The present invention will be described in further detail with reference to the accompanying drawings.

As shown in figure 3, a can eliminate peripheral right angle of part mould that corrugates that takes shape in succession of crimp, including terrace die 1 and die 2, be equipped with shaping hole 5 on the die 2, shaping hole 5 sets to the through-hole, the upper end of shaping hole 5 is equipped with step hole 4, step hole 4's shape is the same with the shape after the part expandes, sets up step hole 4 structure, and it is accurate to fix a position before can making the 3 punching presses of part material, reduces subsequent deburring work, sets up shaping hole 5 to the through-hole simultaneously, makes things convenient for subsequent drawing of patterns.

Further, the thickness of the female die 2 is 20-30 mm larger than the sum of the height of the part edge and the depth of the step hole.

Furthermore, the depth of the stepped hole 4 is not less than the thickness of the part material 3, which can ensure that the part material 3 does not run and move when being stamped.

Further, the punching end of terrace die 1 is equipped with radius angle 6, the both ends of shaping hole 5 also are equipped with the radius angle, and through the both ends radius angle at terrace die 1 and shaping hole 5, when can avoiding the punching press, produce the local too big shearing force that produces in part material 3 surface, form the indentation.

Further, as shown in fig. 4, which is a schematic structural diagram of the oil tank partition, the outer contour of the stepped hole 4 may be set to be the same as the expansion contour of the oil tank partition, and the molding hole may be set to be the same as the outer wall contour of the oil tank partition, so that the oil tank partition can be processed.

Similarly, the technical scheme of the utility model can also be used for processing similar peripheral right-angle continuous edge bending and forming.

The present embodiment is only for explaining the present invention, and it is not limited to the present invention, and those skilled in the art can make modifications of the present embodiment without inventive contribution as needed after reading the present specification, but all of them are protected by patent law within the scope of the claims of the present invention.
