Abstract

The utility model discloses an automobile door bumper punching die which comprises a punch upper sliding block, inclined wedges which are symmetrically arranged on the two sides of the lower part of the punch lower sliding block, and a lower punching die. A first oil cylinder and a second oil cylinder are correspondingly arranged on the front side and the rear side of the middle of the lower punching die. The front end of the first oil cylinder is connected with a mandrel. Cutters are symmetrically arranged on the two sides of the longitudinal centerline of the lower punching die. The rear part of each cutter is connected with a sliding block. The rear part of the sliding block is an inclined surface which is matched with the inclined surface of the inclined wedges. A retaining block is arranged at the rear part of the sliding block. A connecting rod penetrates through the retaining block and is fixedly connected with the sliding block. A spring is sheathed between the tail part of the connecting rod and the retaining block. Moreover, guide blocks are arranged on the two sides of the mandrel. By adopting a punching method to manufacture automobile door bumpers, the utility model has the advantages that the production cost is greatly reduced, and since the two sides are simultaneously punched towards the inside of the bumper, the bumper is not apt to be deformed, the product quality is ensured and the production efficiency is greatly improved.

As depicted in figs. 1 and 2: crash bar 1 is the strength member of a protection personal safety in the automobile door; its both sides need be provided with link 11; automobile door bumper 1 all is high strength welded pipe at present; its hardness is 47~48; tensile strength is more than or equal to 1000MPa, because material is too hard, traditional production method is all finished by plasma cutting; and this kind mode cost is very high, is unfavorable for the market competition of product.
The utility model content
In order to overcome the deficiencies in the prior art, the purpose of this utility model is to provide a kind of die-cut mode that adopts, and increases work efficiency the automobile door bumper die cutting die that reduces cost.
The utility model is achieved through the following technical solutions:
A kind of automobile door bumper die cutting die, it is characterized in that, comprise: the punch press top shoe, be symmetricly set on the wedge and the die-cut counterdie of both sides, punch press top shoe bottom, wherein, both sides, front and back correspondence in the middle of the die-cut counterdie is provided with first oil cylinder and second oil cylinder, the front end of first oil cylinder also connects a plug, and also be symmetrically arranged with cutting knife in the both sides of the longitudinal centre line of die-cut counterdie, the cutting knife rear portion is connected with slide block, the rear portion of slide block is an inclined-plane, it matches with the inclined-plane of above-mentioned wedge, rear portion at slide block also is provided with a block, and a connecting rod runs through block fixedlys connected with slide block, also is with a spring between connecting rod afterbody and block, in addition, also be provided with guide pad on the both sides of plug.
Further, the edge of a knife of above-mentioned cutting knife is the oblique edge of a knife or is the waveform edge of a knife.
The beneficial effects of the utility model are: the utility model is made automobile door bumper by adopting die-cut mode, greatly reduce production cost, in addition, owing to be that the two sides dashes in crash bar simultaneously, guaranteed the displacement degree, crash bar is not yielding, has guaranteed the quality of product, and has improved production efficiency greatly.
Description of drawings
The structural representation of the automobile door bumper that Fig. 1 produces for the utility model;
Fig. 2 is for having the structural representation of the crash bar blank of technology breach before die-cut;
Fig. 3 is the structural representation of the utility model one embodiment;
Fig. 4 is the vertical view of die-cut counterdie described in the utility model.
Main Reference numeral implication is among the figure:
1, crash bar 11, link 12, technology breach 2, punch press top shoe
3, wedge 4, slide block 5, cutting knife 6, block
7, spring 8, guide pad 9, plug 10, connecting rod
The specific embodiment
Below in conjunction with accompanying drawing, describe the specific embodiment of the present utility model in detail:
Fig. 3 is the structural representation of the utility model one embodiment; Fig. 4 is the vertical view of die-cut counterdie described in the utility model.
As shown in Figure 3 and Figure 4: automobile door bumper die cutting die, comprise punch press top shoe 2, be symmetricly set on the wedge 3 and the die-cut counterdie of both sides, punch press top shoe bottom, wherein, both sides, front and back correspondence in the middle of the die-cut counterdie is provided with the first oil cylinder (not shown) and the second oil cylinder (not shown), the front end of first oil cylinder also connects a plug 9, and also be symmetrically arranged with cutting knife 5 in the both sides of the longitudinal centre line of die-cut counterdie, the edge of a knife of cutting knife 5 is the oblique edge of a knife or is the waveform edge of a knife, in the present embodiment, the edge of a knife of cutting knife 5 is the oblique edge of a knife, cutting knife 5 rear portions are connected with slide block 4, the rear portion of slide block 4 is an inclined-plane, it matches with the inclined-plane of above-mentioned wedge 3, also be provided with a block 6, one connecting rods 10 at the rear portion of slide block 4 and run through block 6 and fixedly connected, between connecting rod 10 afterbodys and block 6, also be with a spring 7 with slide block 4, in addition, also be provided with guide pad 8 on the both sides of plug.
Start-up control case power supply, under the effect of control system, first oil cylinder is released plug 9, put into the blank of the crash bar 1 of holding technology breach 12 successfully, second oil cylinder travels forward then, and the plug 9 that is with blank crash bar 1 is pushed in the mould, at this moment, punch press top shoe 2 is descending, wedge 3 moves downward synchronously, cooperates with the inclined-plane of slide block 4, and promotes slide block 4 and cutting knife 5 travels forward, 5 pairs of blank crash bars of cutting knife 1 carry out die-cut, under the effect of connecting rod 10, spring 7 is compressed, finish die-cut and die mould action after, punch press top shoe 1 is up, under the elastic force effect of spring 7, boundary cutting knife 5 and slide block 4 reset, and die-cut waste material is then discharged from the bottom of die-cut counterdie, then, first cylinder action is drawn back plug 9, the second oil cylinders and is also return, and falls down in the slit of crash bar 1 mould that then processes, finish processing, then repetitive operation.
The utility model can make the crash bar one-shot forming, and process velocity is fast, has improved efficiency, processes by adopting die-cut mode, can reduce production costs greatly.
Below disclose the utility model with preferred embodiment, so it is not in order to restriction the utility model, and all employings are equal to replaces or technical scheme that the equivalent transformation mode is obtained, all drops within the protection domain of the present utility model.
