Abstract

The utility model discloses a kind of hole punched device, and product is punched out, which has the hole that surface is blocked, which includes：Cope plate is fixed with upper mold below；Lower template, elastic connection is equipped with lower die thereon, the apparent surface of the lower die and the upper mold has the imitative type face of the product, the product is positioned over the upper surface of the lower die, punch is also fixed in the lower template, after upper mold pushing, the punch is penetrated and exposed by the lower die.When punching press, the upper mold pushes, and the lower die and product are pressed downwardly, and the punch passes through the hole of the product, and the flash in hole is punched.Since the punch is to be located at lower template, it is punched by the lower section of product along the existing hole of product, existing hole has guiding role to the punch of entrance.Therefore, for the size product that there is any discrepancy without hole punched device is needed to change, avoid the problem that replacement hole punched device is frequent；And it effectively prevents product and the problem of collapsing is rushed by punching partially.

Description

Hole punched device

【Technical field】

The utility model is related to a kind of hole punched devices, and in particular to the hole punched device of flash in a kind of hole punching.

【Background technology】

It please refers to Fig.1, Fig. 2, Fig. 1 is a kind of product positive structure schematic, and Fig. 2 is that the backside structure of the product is illustrated Figure.

As shown in the figure, the product 100 has hole 101 to be punched, which has had in terms of 100 back side direction of product There is certain depth (referring to Fig. 2), and also there is certain thickness flash 102 to block hole 101 from the point of view of the front of product 100. It is two cave of a mould shown in figure, is once punched out there are two product 100.There is the material head of connection between two products 100 103。

The prior art is that product 100 is face-up placed on to the lower die of hole punched device to fix in the way of Fig. 1, and The upper mold of hole punched device has punch, and upper mold drives punch to move downward during punching, and the flash 102 got lodged on hole 101 is washed out.

However, using above-mentioned hole punched device, in the case where product 100 has a little variation, the position dimension in hole 101 can phase It should change, it is necessary to replace different hole punched devices, influence production efficiency.If being changed without hole punched device, product is be easy to cause 100 are collapsed by punching punching partially, and 100 fraction defective of product is caused to increase and repair a die frequency increase.

In view of this, it is really necessary to provide a kind of hole punched device, to solve the above problems.

【The content of the invention】

Therefore, the purpose of this utility model is to provide a kind of hole punched device, solve to replace hole punched device during punching frequently with And easily the problem of product fraction defective is high is collapsed in punching punching partially in punching.

In order to achieve the above object, the hole punched device of the utility model, is punched out product, which blocks up with surface Hole firmly, the device include：

Cope plate is fixed with upper mold below；

Lower template, thereon elastic connection be equipped with lower die, the apparent surface of the lower die and the upper mold has the product Imitative type face, the product is positioned over the upper surface of the lower die, punch is also fixed in the lower template, in the upper mold After pushing, the punch is penetrated and exposed by the lower die.

Optionally, which further includes lead, and the lower template, the upper mold sleeve-board are fixed in described lead one end Arranged on the lead.

Optionally, Kong Weisan of the product, the punch corresponds to three.

Optionally, connected between the lower template and the lower die using spring.

Optionally, what the upper mold pushed is driven to oil hydraulic cylinder.

Compared to the prior art, the hole punched device of the utility model, when punching press, the upper mold pushes, the lower die and Product is pressed downwardly, and the punch passes through the hole of the product, and the flash in hole is punched.Since the punch is to be located at down Template is punched by the lower section of product along the existing hole of product, and existing hole has guiding role to the punch of entrance.Therefore, For the size product that there is any discrepancy without hole punched device is needed to change, avoid the problem that replacement hole punched device is frequent；And due to this Guiding role effectively prevents product and rushes the problem of collapsing partially by punching, improves product yield；Reduce the frequency that repairs a die.

【Specific embodiment】

Please refer to Fig. 3, Fig. 4, Fig. 3 be one preferred embodiment of hole punched device of the utility model three-dimensional structure diagram, Fig. 4 is the decomposition chart of one preferred embodiment of hole punched device of the utility model.

In order to achieve the above object, the hole punched device of the utility model is punched out product 100, which has The hole 101 (please referring to Fig. 1, Fig. 2) that surface is blocked, the device include：

Cope plate 201 is fixed with upper mold 202 below；

Lower template 203, elastic connection is equipped with lower die 204, the apparent surface of the lower die 204 and the upper mold 202 thereon Imitative type face with the product 100, the product 100 are positioned over the upper surface of the lower die 204, in the lower template 203 Punch 205 is also fixed with, after the upper mold 202 pushing, the punch 205 is penetrated and exposed by the lower die 204.

Wherein, which further includes lead 206, and the lower template 203 is fixed in described 206 one end of lead, described Cope plate 201 is sheathed on the lead 206.

Wherein, the hole 101 of the product 100 is three, and the punch 205 corresponds to three.

Wherein, connected between the lower template 203 and the lower die 204 using spring (not shown) so that under upper mold 202 During pressure, the gap between the lower die 204 and lower template 203 becomes smaller, and then the punch 205 is pierced by by the lower die 204.

Wherein, the driving that the upper mold 202 pushes can be oil hydraulic cylinder.

Fig. 5, Fig. 6 are please referred to, Fig. 5 is locally tied before the punching for one preferred embodiment of hole punched device of the utility model Composition, Fig. 6 are local structural graph after the punching of one preferred embodiment of hole punched device of the utility model.

The hole punched device of the utility model, when punching press, the upper mold 202 pushes, 100 quilt of the lower die 204 and product It presses down on, the punch 205 passes through the hole 101 of the product 100, and the flash 102 in hole 101 is punched.The upper mold 202 Also there is the structure of punching material head 103, the material head 103 is also washed out.

Please in conjunction with refering to Fig. 7, Fig. 7 is the structure diagram after product punching.

Since the punch 205 is to be located at lower template 203, by the lower section of product 100 along the existing hole 101 of product 100 Punching, existing hole 101 have guiding role to the punch 205 of entrance.Therefore, for 100 nothing of the size product that there is any discrepancy Hole punched device is needed to change, avoids the problem that replacement hole punched device is frequent；And due to the guiding role, effectively prevent product 100 rush the problem of collapsing partially by punching, improve 100 yield of product；Reduce the frequency that repairs a die.

It is noted that the utility model is not limited to the above embodiment, any person skilled in the art is based on Any simple modification, equivalent change and modification that technical solutions of the utility model make above-described embodiment, both falls within this practicality In new protection domain.
