Description

Punching and cutting die

Technical Field

The utility model relates to a mould field indicates a cutting die punches a hole especially.

Background

Stamping die is a instrument of processing metalwork, and L shape aluminium alloy radiator needs to use the aluminum product of L shape, generally uses a mould to cut the material earlier, then uses another mould to punch a hole the material again, and production technology is complicated, and material utilization is low, and production efficiency is lower.

Disclosure of Invention

The utility model aims to solve the problem that a cut off mould punches a hole is provided, simplifies the production process, improves production efficiency, reduces the material loss.

Solve above-mentioned technical problem according to the utility model provides a pair of cut-off die punches a hole, contain the mould, the lower mould, it contains the upper die base that down sets gradually from the last to go up the mould, the upper padding plate, the punch holder, go up the baffle, go up and take off the flitch, the lower mould contains the lower bolster that down sets gradually from the last, the die holder, it sets up the compound die activity space that forms the mould to go up baffle and punch holder interval, be provided with shutdown mechanism and towards the needle on the punch holder, shutdown mechanism contains the last mould slider of sliding connection on the punch holder, fixed connection is at the die-cut piece of last mould slider bottom, die-cut piece bottom one side is provided with first direction inclined plane, die-cut piece bottom opposite side is provided with the edge of a knife, lower bolster top fixedly connected with slide, slide one end is provided with the second direction inclined plane that matches with first direction inclined plane.

Preferably, the upper stripper plate is provided with a punch guide insert, and the punch pin penetrates through the punch guide insert.

The utility model has the advantages that: the utility model provides a cut-off die punches a hole, set up unique assembly structure, with L shape aluminum product location at the lower die plate top, promote the upper die base and carry out the compound die operation, the punch holder makes progress the lateral movement of backstop board under the drive of upper die base, towards needle and die-cut piece will be to L shape aluminum product lateral shifting, when first direction inclined plane butt is on second direction inclined plane, die-cut piece receives the reverse acting force of slide and to L shape aluminum product lateral shifting, thereby carry out die-cut operation to L shape aluminum product, it carries out the operation of punching a hole to L shape aluminum product to dash simultaneously, the production process has been simplified, reduce the material loss, and the production efficiency is effectively improved.

Drawings

Fig. 1 illustrates a schematic structural diagram of the present invention.

The reference numbers illustrate: the punching die comprises an upper die holder 1, an upper padding plate 2, an upper clamping plate 3, an upper stop baffle 4, an upper stripper plate 5, a lower die plate 6, a lower die holder 7, a punching pin 8, an upper die sliding block 9, a punching part 11, a first guide inclined plane 110, a knife edge 111, a sliding seat 12, a second guide inclined plane 120 and a punch guide insert 13.

Detailed Description

In order to make the objects, technical solutions and advantages of the embodiments of the present disclosure more apparent, the technical solutions of the embodiments of the present disclosure will be described clearly and completely with reference to the drawings of the embodiments of the present disclosure. It is to be understood that the described embodiments are only a few embodiments of the present disclosure, and not all embodiments.

All other embodiments of the person skilled in the art, which are obtained without inventive work on the basis of the described embodiments of the present disclosure, are within the scope of protection of the present disclosure.

Refer to fig. 1.

The utility model provides a cut-off die punches a hole, contain the mould, the lower mould, it contains from last upper die base 1 that down sets gradually to go up the mould, the upper padding plate 2, punch holder 3, go up stop baffle 4, go up and take off flitch 5, the lower mould contains from last lower bolster 6 that down sets gradually, die holder 7, it sets up the compound die activity space that forms the mould to go up stop baffle 4 and 3 intervals of punch holder, be provided with shutdown mechanism and towards needle 8 on the punch holder 3, shutdown mechanism contains last mould slider 9 of sliding connection on punch holder 3, fixed connection is at the die-cut piece 11 of last mould slider 9 bottom, 11 bottom one side of die-cut piece is provided with first direction

inclined plane

110, 11 bottom opposite sides of die-cut piece are provided with edge of a

knife

111, 6 top fixedly connected with slide 12 of lower bolster, 12 one end of slide is provided with the second direction inclined plane 120 that matches with first direction inclined plane 110.

The specific use principle is as follows: the L-shaped aluminum material is positioned at the top of the lower die plate 6, the upper die base 1 is pushed to perform die assembly operation, the upper clamping plate 3 is driven by the upper die base 1 to move towards the upper stop plate 4, the punching pin 8 and the punching piece 11 move towards the L-shaped aluminum material side, when the first guide inclined plane 110 abuts against the second guide inclined plane 120, the punching piece 11 moves towards the L-shaped aluminum material side under the action of reverse force of the sliding base 12, and oblique movement of a knife edge 111 is formed, so that punching operation is performed on the L-shaped aluminum material, and meanwhile, the punching pin 8 performs punching operation on the L-shaped aluminum material, so that the production process is simplified, material loss is reduced, and the production efficiency is effectively improved.
