Description

Inclined punching wedge structure

Technical Field

The utility model belongs to the technical field of the stamping die technique and specifically relates to a slide wedge structure.

Background

In the prior art, when punching holes on the inclined plane of a product, the adopted method is to firstly punch holes by twisting the material belt and then twist the material belt, and the method has the disadvantages of complex structure, high cost and difficulty in ensuring punching precision.

Accordingly, there is a need in the art for improvements and improvements.

SUMMERY OF THE UTILITY MODEL

To the weak point that exists among the prior art, the utility model aims at providing a rational in infrastructure, with low costs, the high oblique towards slide wedge structure of precision of punching a hole.

The utility model discloses a realize above-mentioned purpose through following technological means:

an inclined punching wedge structure comprises an upper die and a lower die, wherein the lower die comprises a lower die base and a lower die plate, the lower die plate is mounted on the lower die base, and a knife edge insert is obliquely mounted on the lower die plate; the upper die comprises an upper die base, a stripper plate, a mounting base, a sleeve, an ejector rod, a wedge and a punch, wherein two nitrogen springs are arranged between the upper die base and the stripper plate, the sleeve passes through the mounting base and is arranged on the stripper plate, the sleeve is provided with a sliding cavity, the punch is slidably arranged in the sliding cavity, the handle end of the punch is connected with the ejector rod, the punch is sleeved with the spring, the ejector rod is matched with a left inclined surface of the lower part of the wedge below the upper die base, and the head end of the punch is penetrated out of the bottom of the sliding cavity and matched with the knife edge insert.

Preferably, the top of the sleeve is matched with a cover plate, and the opposite ejector rod penetrates out of the cover plate to be matched with the left inclined plane.

Preferably, the punch handle end is externally sleeved with a punch clamping plate.

Preferably, the left side of the lower template is provided with a leaning block fixed on the lower die base.

Compared with the prior art, the beneficial effects of the utility model are that:

due to the adoption of the structural design, the punch is arranged on the stripper plate through the sleeve, the stripper plate firstly presses a product under the action of the nitrogen spring, the upper die base continuously descends to punch a hole through the ejector rod driving punch, the occupied space is small, the structure is compact, the material belt is shortened, and the cost is low.

Drawings

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

The reference numbers in the figures are respectively: (1) the device comprises a lower die base, (2) a lower die plate, (3) a knife edge insert, (4) an upper die base, (5) a stripper plate, (6) a mounting base, (7) a sleeve, (8) a pair of ejector rods, (9) a wedge, (10) a punch, (11) (12) a nitrogen spring, (13) a sliding cavity, (14) a spring, (15) a left inclined surface, (16) a cover plate, (17) a punch clamping plate and (18) a backup block.

Detailed Description

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

referring to fig. 1, the utility model relates to an inclined punching wedge structure, which comprises an upper die and a lower die, wherein the lower die comprises a lower die holder 1 and a lower die plate 2, the lower die plate 2 is mounted on the lower die holder 1, and a knife edge insert 3 is obliquely mounted on the lower die plate 2; go up the mould and include upper die base 4, take off flitch 5, mount pad 6, sleeve 7, to ejector pin 8, slide wedge 9 and drift 10, upper die base 4 with take off and be equipped with two

nitrogen spring

11 and 12 between the flitch 5, sleeve 7 passes through mount pad 6 install in take off on the flitch 5, sleeve 7 is equipped with sliding chamber 13, drift 10 slidable mounting in sliding chamber 13, the handle end of drift 10 is connected with to ejector pin 8, drift 10 overcoat has spring 14, to ejector pin 8 with the upper die base below the left inclined plane 15 of slide wedge 9 lower part cooperate, the head end of drift 10 is worn out sliding chamber bottom with the edge of a knife is gone into son 3 and is cooperateed.

When the utility model works and the mould is closed, the punch drives the upper mould base to move downwards, and the stripper plate firstly presses the product under the action of the nitrogen spring; the upper die base continues to move downwards, the wedge fixed on the upper die base starts to contact the ejector pin, then the ejector pin drives the punch to complete punching, and meanwhile, the spring is compressed; when the die is opened, the upper die base moves upwards, the stripper plate is kept still under the action of the nitrogen spring, and the punch is reset under the action of the spring; and after the stroke of the nitrogen spring is finished, the stripper plate and the upper die base move upwards together to finish stripping.

The top of the sleeve is matched with a cover plate 16, and the pair of ejector rods 8 penetrate out of the cover plate to be matched with the left inclined plane.

And a punch clamping plate 17 is sleeved outside the punch handle end.

And a rest block 18 fixed on the lower die base is arranged on the left side of the lower die plate.

To sum up, the utility model discloses an foretell structural design solves the weak point among the prior art, has characteristics such as rational in infrastructure, with low costs, the precision height of punching a hole.
