Description
Technical field
The utility model relates to a kind of improvement of press-through die, refer in particular to it is a kind of product surface can be prevented uneven, corrugation
Press-through die.
Background technique
In the prior art, as shown in Fig. 1, press-through die includes cavity plate 1 and punch-pin 2；The height of the punch-pin 2 is from one
It holds toward the other end and gradually decreases；The least significant end of the punch-pin 2 is provided with flanging portion 4；Drawing material 3 is placed on the punch-pin 2；Institute
The top that punch-pin 2 is arranged in cavity plate 1 is stated, when cavity plate 1 pushes, drawing is carried out to drawing material 3 with the cooperation of punch-pin 2, and simultaneously
Flanging (not shown) is formed between cavity plate 1 and flanging portion 4.The press-through die of this structure, since the height of punch-pin 2 is from one
It holds toward the other end and gradually decreases, when cavity plate 1 pushes, when carrying out drawing to drawing material 3 with the cooperation of punch-pin 2, be easy to cause production
Product uneven surface, corrugation.
For this purpose, we have developed it is a kind of product surface can be prevented uneven, corrugated press-through die.
Utility model content
The utility model aim be for overcome the deficiencies in the prior art and provide it is a kind of product surface can be prevented uneven,
Corrugated press-through die.
In order to achieve the above objectives, the technical solution adopted in the utility model is: a kind of press-through die, comprising cavity plate and convex
Mould；The height of the punch-pin is gradually decreased from high-end past low side, while forming a lug boss in the low side of punch-pin；The cavity plate
Least significant end be provided with turn-up portion；The turn-up portion is located at the outside of lug boss；The height of the turn-up portion is low lower than punch-pin
The height at end；Drawing material is placed on the punch-pin；The top of punch-pin is arranged in the cavity plate, when cavity plate pushes, with punch-pin
Cooperation carries out drawing to drawing material, and forms flange between the turn-up portion of cavity plate and the upper projecting portion of punch-pin simultaneously.
Preferably, the height of the lug boss is higher than the high-end height of punch-pin.
Preferably, height of the height of the turn-up portion lower than the low side of punch-pin.
Due to the application of the above technical scheme, the utility model has the advantage that compared with prior art
The height of press-through die convex mould described in the utility model is gradually decreased from high-end past low side, is conducive to drawing
Prolong material and carry out deep-drawing, while the low side of punch-pin is provided with lug boss, makes to inhibit drawing material progress deep-drawing, drop
The speed of low deep-drawing can occur to avoid product surface unevenness, corrugated situation.
Detailed description of the invention
Technical solutions of the utility model are described further with reference to the accompanying drawing:
Attached drawing 1 is the schematic diagram of the press-through die of the prior art；
Attached drawing 2 is the schematic diagram of press-through die described in the utility model；
Wherein: 1, cavity plate；2, punch-pin；3, drawing material；4, flanging portion；11, cavity plate；12, punch-pin；13, turn-up portion；14,
Lug boss.
Specific embodiment
With reference to the accompanying drawing and specific embodiment the utility model is described in further detail.
Attached drawing 2 is press-through die described in the utility model, includes cavity plate 11 and punch-pin 12；The height of the punch-pin 12
It is gradually decreased from high-end past low side, while forming a lug boss 14 in the low side of punch-pin 12；The height of the lug boss 14 is high
In the high-end height of punch-pin 12.
The least significant end of the cavity plate 11 is provided with turn-up portion 13；The turn-up portion 13 is located at the outside of lug boss 14.It is described
Height of the height of turn-up portion 13 lower than the low side of punch-pin 12.
Drawing material 3 is placed on the punch-pin 12；The top of punch-pin 12 is arranged in the cavity plate 11, when cavity plate 11 pushes
When, drawing is carried out to drawing material 3 with the cooperation of punch-pin 12, and the lug boss in the turn-up portion 13 of cavity plate 11 and punch-pin 12 simultaneously
Flange (not shown) is formed between 14.
When work, since the height of the punch-pin 12 is gradually decreased from high-end past low side, be conducive to carry out drawing material 3
Deep-drawing, while the low side of punch-pin 12 is provided with lug boss 14, makes to inhibit the progress deep-drawing of drawing material 3, reduce deep
The speed of drawing can occur to avoid product surface unevenness, corrugated situation.
Due to the application of the above technical scheme, the utility model has the advantage that compared with prior art
The height of press-through die convex mould 12 described in the utility model is gradually decreased from high-end past low side, is conducive to pair
Drawing material 3 carries out deep-drawing, while the low side of punch-pin 12 is provided with lug boss 14, make to carry out drawing material 3 deep-drawing into
Row inhibits, and reduces the speed of deep-drawing, can occur to avoid product surface unevenness, corrugated situation.
The above is only the specific application examples of the utility model, do not constitute any limit to the protection scope of the utility model
System.Any technical scheme formed by adopting equivalent transformation or equivalent replacement, all fall within the utility model rights protection scope it
It is interior.
