Abstract

The utility model discloses square hole clear angle die, described die is solid die, and the centre of described die has the square hole of hollow out, and the top of the horn at four angles of described square hole offers groove.The utility model can ensure the clear angle of the square hole of the product obtained and impulse-free robustness when not increasing manufacturing procedure.

Description

Square hole clear angle die

Technical field

The utility model relates to mould applications, particularly relates to a kind of square hole clear angle die.

Background technology

The support bracket fastened position degree of Sensor core parts and square hole precision determine the properties of product of sensor, and when transfer matic is produced, square hole must clear angle and the yield rate of impulse-free robustness guarantee product and production efficiency.In thin plate class hardware stamping part, product square hole place burr is comparatively large and square hole always has fillet to exist under magnifying glass, as shown in Figure 1, because the product produced is less, when clear angle process, die adopts assembled piece type to realize square hole clear angle processing, the intensity of its tile configuration can not ensure requirements of mass production, and generally always can there is in the corner of square hole the fillet that radius is at least 0.02mm.

Utility model content

The utility model provides a kind of square hole clear angle die, can ensure the clear angle of the square hole of the product obtained and impulse-free robustness when not increasing manufacturing procedure.

For solving the problems of the technologies described above, the technical scheme that the utility model adopts is:

There is provided a kind of square hole clear angle die, described die is solid die, and the centre of described die has the square hole of hollow out, the top of the horn at four angles of described square hole offers the groove of arc-shaped.

In a preferred embodiment of the present utility model, the radius of described groove is 0.03 ~ 0.07mm.

In a preferred embodiment of the present utility model, the punching press gap of described die is 0.02 ~ 0.03mm.

The beneficial effects of the utility model are: the utility model square hole clear angle die, die is splicedly improved to monoblock type from traditional, and small groove is increased on the corner of square hole, punching press obtains when not increasing operation the clear angle of product square hole can be ensured and impulse-free robustness, spliced clear angle die is replaced with monoblock type clear angle die, production cost can be reduced, and life-span more spliced clear angle die extends 10 times.

Accompanying drawing explanation

Fig. 1 is the structural representation of traditional spliced clear angle die;

Fig. 2 is the structural representation of a preferred embodiment of the present utility model;

Fig. 3 is the partial enlarged drawing of Fig. 2;

In accompanying drawing, the mark of each parts is as follows: 1, square hole, and 2, groove.

Detailed description of the invention

Below in conjunction with accompanying drawing, preferred embodiment of the present utility model is described in detail, to make advantage of the present utility model and feature can be easier to be readily appreciated by one skilled in the art, thus more explicit defining is made to protection domain of the present utility model.

Refer to accompanying drawing, the utility model embodiment comprises:

A kind of square hole clear angle die, this die is solid die, and centre has the square hole 1 of hollow out, and the top of the horn at four angles of square hole 1 all has outside small arc-shaped groove 2, and the radius of groove 2 is 0.03 ~ 0.07mm, and the punching press gap of this die is 0.02 ~ 0.03mm.This square hole clear angle die mainly applies in the preparation of infrared sensor pipe cap, for the square hole 1 of infrared sensor pipe cap is carried out angle shaping step clearly.Infrared sensor pipe cap size is less, required precision is quite high, minute recesses 2 on square hole 1 four jiaos, be equivalent to be provided with negative angle on square hole 1 four jiaos, coordinate the control in die punching press gap, square hole clear angle, inwardly closed pressure can be produced to the corner of the square hole 1 that product stamps out through punching press action rearward recess 2, the clear angle of product square hole 1 that punching press obtains can be ensured and impulse-free robustness.

The foregoing is only embodiment of the present utility model; not thereby the scope of the claims of the present utility model is limited; every utilize the utility model description and accompanying drawing content to do equivalent structure or equivalent flow process conversion; or be directly or indirectly used in other relevant technical fields, be all in like manner included in scope of patent protection of the present utility model.

Claims
