Description
Technical field
The present invention relates to Stamping Die Technology field, especially relate to the side blow mechanism in a kind of diel.
Background technology
Press Tools for Automobiles rushes in forming process repairing, and due to the side blow structure problem that shape of product and holes of products position determine, often can occur the side punching that plate centre suspention angle is larger.
In current Design of Dies, the normal wide-angle side blow adopting pressure core wedge and gap bridge wedge to realize centre; As shown in Figure 2, the side punching that existing plate centre suspention angle is larger, adopt large wedge to overlap the bridge type wedge of little Wedge type, the space that existing bridge type wedge needs is larger, and middle bridge portion has a strong impact on large wedge slide block intensity; Particularly narrower less plate, often because insufficient space, causes side blow to be difficult to realize.
Summary of the invention
Not enough for prior art, technical problem to be solved by this invention is to provide the side blow mechanism in a kind of diel, to reach the object in the space reduced required for side blow mechanism.
In order to solve the problems of the technologies described above, the technical solution adopted in the present invention is:
Side blow mechanism in this diel, comprise holder and drift fixed block and press core, described drift fixed block lower end is provided with drift, described holder comprises pedestal and forces backhaul to hook, pedestal top is connected with upper mould body, and drift fixed block tilts slidably to be located at pressure in-core, and pedestal bottom is provided with the inclined-plane corresponding with drift fixed block upper surface, forcing backhaul to hook is located on pedestal, and the hook forcing backhaul to hook is located in groove that drift fixed block is arranged.
Further, described pressure in-core is provided with inclined hole, and drift fixed block is slidably located in inclined hole.
It is an overall structure that described pedestal and pressure backhaul hook.
Described pedestal was worked hard in glove with demountable structure with pressure backhaul and was connected.
Groove on described drift fixed block is the groove being located at drift fixed block side.
Guide pin bushing is provided with, drift fixed block and guide pin bushing matched in clearance in the inclined hole of described pressure core.
The width of described groove is greater than the hook width forcing backhaul to hook.
The inclined-plane in described pressure backhaul hook and fit depressions face.
Described pressure core is provided with the limited block to the spacing location of guide pin bushing.
The present invention compared with prior art, has the following advantages:
Carry out the guiding of slide block by holder and force backhaul, simplifying the base construction of existing wedge; Undertaken leading by drift fixed block and guide pin bushing in punching course and simplify the slide block structure of existing wedge, structure is simple, reliable and stable, substantially reduce the space required for side blow mechanism, compact conformation, take up room little, be convenient to arrange and assembling, larger suspention angle side punching can be carried out in the easy plate centre that realizes.
Accompanying drawing explanation
Below the content expressed by each width accompanying drawing of this description and the mark in figure are briefly described:
Fig. 1 is side blow mechanism structure schematic diagram of the present invention.
Fig. 2 is existing side blow mechanism structure schematic diagram.
In figure: 1. pedestal, 2. drift fixed block, 3. pressure backhaul hook, 4. guide pin bushing, 5. limited block, 6. pressure core.
Detailed description of the invention
Contrast accompanying drawing below, by the description to embodiment, the specific embodiment of the present invention is described in further detail.
As shown in Figure 1, side blow mechanism in this diel, comprise holder and drift fixed block 2 and press core 6, wherein, holder is used for location and drives drift fixed block 2, drift fixed block 2 lower end is provided with drift, realizes side punching by drift, and drift fixed block 2 tilts slidably to be located in pressure core 6.
Holder comprises pedestal 1 and forces backhaul to hook 3, and the top of pedestal 1 is connected with upper mould body, can move up and down with upper mould body, and the top of forcing backhaul to hook 3 is fixed on pedestal 1; Wherein, force backhaul to hook 3 and can be an overall structure with pedestal 1, structure is simple; Or force backhaul to hook 3 to be connected by demountable structure with between pedestal 1, be namely connected by screw, be convenient to dismounting and change and safeguard.
Drift fixed block 2 tilts slidably to be located in pressure core 6, is specially, and is provided with inclined hole in pressure core 6, is provided with guide pin bushing 4 in the inclined hole of pressure core 6, and drift fixed block 2 and guide pin bushing 4 matched in clearance, drift fixed block 2 can in the tilted slip of guide pin bushing 4.Pressure core 6 is provided with the limited block 5 to the spacing location of guide pin bushing, and limited block 5 outer end is fixed by screws in pressure core top, and guide pin bushing is pushed down in limited block 5 the inner, is fixed on the positioning guide pin bushing, and guide pin bushing is convenient to installation and removal.
Pedestal 1 bottom is provided with the inclined-plane corresponding with drift fixed block 2 upper surface, and the hook forcing backhaul to hook 3 is actively installed in the groove of setting on drift fixed block 2.Can along the inclined-plane relative motion that matches between pedestal and drift fixed block.
Groove on drift fixed block 2 is the groove being located at drift fixed block side, the width of groove is greater than the hook width forcing backhaul to hook, hook is movable at groove, the inclined-plane in hook and the fit depressions face of forcing backhaul to hook, pressure backhaul hook with can along the inclined-plane relative motion that matches between the two between drift fixed block.
Suspend in midair on the basis of the larger side punching mechanism of angle in conventional plate centre, carry out structure innovation, smart design, change the form of holder, the guide plate that is confined in the past is led, pressing plate is spacing, flexible member backhaul, and the present invention is hooked by the pressure backhaul of wedge and forces backhaul essence to come to holder integral piece.
During mold movement, drift fixed block one end is in pedestal and hooks in the holder formed with forcing backhaul, one end is in guide pin bushing, during such mould setting in motion, guide pin bushing can impel drift fixed block to move on pressing direction, and drift fixed block and guide pin bushing play the guiding role and can meet the required precision of punching simultaneously; When mould continues motion, one end of drift fixed block and base into contact, between the two relative motion, meet the requirement of punching to power by the angle of inclination of pedestal.
During mould die sinking, when patrix moves upward, force backhaul to hook to move upward with holder and upper mould body, the angle of forcing backhaul to hook is consistent with the angle of bevel of pedestal, drift fixed block is so just impelled to force rollback under the effect forcing backhaul to hook, and the power of rollback is provided by the holder being fixed on patrix, meet the requirement of punching material returned power.
Now the other end of drift fixed block is still in guide pin bushing, so just can guarantee that the rollback direction of drift is the pressing direction rollback along punching, thus reaches and simplify the exquisite large angle side punching that completes plate centre.
Above by reference to the accompanying drawings to invention has been exemplary description; obvious specific implementation of the present invention is not subject to the restrictions described above; as long as have employed the improvement of the various unsubstantialities that design of the present invention and technical scheme are carried out; or design of the present invention and technical scheme directly applied to other occasion, all within protection scope of the present invention without to improve.
