Description

The piercing on rectangular tube device

Technical field

The utility model relates to a kind of machinery processing apparatus, is specifically related to a kind of device that is used for piercing on rectangular tube.

Background technology

In the prior art; Carry out the hole adds and all accomplishes through drilling machine man-hour on the square tube surface; Because adopting the operation format of drill bit punching not only wastes time and energy; And the consumption of drill bit and to damage cost higher, so this form processing not only increases manual work and equipment cost, and cause high percent defective easily.

The utility model content

The utility model technical problem to be solved is to provide a kind of piercing on rectangular tube device that can effectively improve square tube surface perforate efficient.

Its technical problem to be solved can be implemented through following technical scheme.

A kind of piercing on rectangular tube device, its characteristics do, comprising:

One base;

One lays the die of treating the punching square tube, and said die surface offers material-dropping hole; Said die is fixed on the said base through a location briquetting;

Be installed in the vertical guide pillar on the said base;

The holding pad that after said vertical guide pillar guiding, can be shifted up and down, said holding pad are used for compressing treats the punching square tube; And the drift fixed head that after said vertical guide pillar guiding, can be shifted up and down, being installed on staking punch on the said drift fixed head, said drift fixed head is located at said holding pad top; The top of said holding pad is provided with a compression spring, offers staking punch on the said briquetting plate and dodges the hole; And

Armoring die shank and the cope match-plate pattern that connects said die shank on punch press.

As the further improvement of present technique scheme, said location briquetting is the channel-section steel of the outer flanging of one or two side direction, offers the connecting hole that connects said base on the described flanging in both sides.

Also as the further improvement of present technique scheme, said compression spring is installed in the receiver, and retaining part stretches out the upper opening of said receiver.

Adopt the piercing on rectangular tube device of technique scheme, through the frock clamp of a quick punching press is set, realizing piercing on rectangular tube task quickly and easily, and then improved the operating efficiency of piercing on rectangular tube, effectively reduce processing cost.

Description of drawings

Below in conjunction with accompanying drawing the specific embodiment of the utility model being done one specifies.

Fig. 1 is the structural representation of the utility model;

Fig. 2 is the front view of this device;

Fig. 3 is the vertical view of Fig. 2;

The specific embodiment

Like Fig. 1 to piercing on rectangular tube device shown in Figure 3; Comprise base 100; Be fixed on the base 100 through locating piece 210 with treating the die 200 that hole size adapts in the punching square tube, wherein locating piece 210 is that the outside flanging in U-lag steel both sides forms, and offers locating hole 212 on the flanging 211 of both sides; Through locating hole 212 and mounting screw, die 200 is fixed on the base.About two guide posts 300 insert on base 100; From top to bottom; 300 pairs of drift fixed heads of guide post 600 and holding pad 400 position guiding at vertical direction, and wherein holding pad 400 is to be used for compressing the square tube of treating punching, offers drift on the holding pad 400 and dodges hole 410; Also be provided with a receiver 420 on the holding pad 400, lay compression spring 430 in the receiver 420; Under non-impaction state, the upper opening of receiver 420 is stretched out in the part, top of compression spring 430.

The bottom of drift fixed head 600 is connected with drift 500.Impact through the cope match-plate pattern 700 on drift fixed head 600 tops; Drift 500 is along with drift fixed head 600 is downward; Pass through drift and dodge hole 410 back impacts to being enclosed within treating on the punching square tube on the die 200; For the ease of institute's punching material is separated with the square tube body, be provided with material-dropping hole in the corresponding position of die 200.Cope match-plate pattern 700 is connected with punch press through die shank 710, so that lasting impulse force to be provided.

In drift fixed head 600 decline processes, its lower surface touches compression spring 430 and with its compression, after punching was accomplished, the elastic force of dependence compression spring 430, drift fixed head 600 are upspringed along guide post 300 returned the position, for punching is next time got ready.

When this hole punched device is used for piercing on rectangular tube, has the advantage that punching press is convenient, efficient, cost is low.
