Abstract

The utility model provides a one-step forming device for bent pipe different-face holes, and relates to the technical field of automatic forming. The one-step forming device for the bent pipe different-face holes particularly comprises a fixed slide table (1), an upper die (2), a horizontal trimming die (3), a steel sleeve (4), a pipe to be machined (5) and a lower die (6). A groove of the lower die (6) is used for containing a pipe to be formed, the upper die (2) moves towards the lower die (6) after the pipe to be formed is fixed, the horizontal trimming die (3) is connected with the fixed slide table (1), and a punch of the horizontal trimming die (3) penetrates through the steel sleeve (4). According to the one-step forming device for the bent pipe different-face holes, one-step forming is achieved, operation is simple, position tolerance precision is high, and efficiency is high.

Description

Crooked pipe antarafacial hole one-shot forming apparatus

Technical field

The utility model relates to the automatic moulding technical field, relates in particular to a kind of crooked pipe antarafacial hole one-shot forming apparatus.

Background technology

Present domestic many manufacturers all can run into punching on the antarafacial position of punching on pipe, particularly some crooked pipes, as scheme pipe to be formed as Pipe forming enterprise.Common way was first pipe to be placed on counterdie to fix in the past, rush a hole, and then the pipe of another face is placed into counterdie fixes, rush another hole, will cause twice punch forming like this, need two pairs of moulds, the locus when punching can be caused in twice location simultaneously between hole and hole is offset, the while decrease in efficiency, cost rises.

Therefore, instantly need a urgent technical problem that solves to be exactly: a kind of effective measures of proposition how can innovate, to satisfy the demand of practical application.

The utility model content

Outside the deficiency that exists in the problems referred to above, the utility model provides a kind of crooked pipe antarafacial hole one-shot forming apparatus, can one-shot forming and simple to operate, and the position of related features precision is high, the device that efficient is high.

In order to address the above problem, the utility model provides a kind of crooked pipe antarafacial hole one-shot forming apparatus, comprise fixedly slide unit (1), patrix (2), horizontal punch die (3), steel bushing (4), pipe to be processed (5) and counterdie (6), wherein, the groove of counterdie (6) is used for placing pipe to be formed, after pipe to be formed is fixing, patrix (2) is mobile to counterdie (6), horizontal punch die (3) is connected with fixing slide unit (1), and the drift of described horizontal punch die (3) passes steel bushing (4).

Further, described horizontal punch die (3) is connected by oat tail groove structure with fixing slide unit (1).

Compared with prior art, the utlity model has following advantage:

At first, this device changes the direction of active force by the effect on inclined-plane and inclined-plane, make the antarafacial hole one-shot forming of crooked pipe, reduce production costs, can save a mold, efficient is high, has eliminated the accumulated error that causes due to multiple bearing, and the machining accuracy of product is improved.

Secondly with the oat tail groove structure guiding, guarantee the motion stabilization of horizontal punch die, lead precisely at first, this device is easy to use, with low cost, and efficient is high.

Description of drawings

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

Fig. 2 is the done state schematic diagram of crooked pipe antarafacial of the present utility model hole one-shot forming apparatus.

The specific embodiment

In order to make the purpose of this utility model, technical scheme and advantage clearer, below in conjunction with accompanying drawing and example, the utility model is described in further detail.But example is not as to restriction of the present utility model.

As shown in Figure 1, the utility model provides a kind of crooked pipe antarafacial hole one-shot forming apparatus, comprise fixedly slide unit (1), patrix (2), horizontal punch die (3), steel bushing (4), pipe to be processed (5) and counterdie (6), wherein, the groove of counterdie (6) is used for placing pipe to be formed, after pipe to be formed is fixing, patrix (2) is mobile to counterdie (6), and horizontal punch die (3) is connected with fixing slide unit (1), and the drift of described horizontal punch die (3) passes steel bushing (4).

Below introduce in detail principle and the course of work of crooked pipe antarafacial hole one-shot forming apparatus.Referring to figure crooked pipe antarafacial hole one-shot forming apparatus (original state can referring to Fig. 1), pipe to be formed is put in the groove of counterdie, the position is fixed, patrix begins down to move, the right of patrix has one to become the inclined-plane of 60 ° with horizontal plane, patrix down simultaneously, the elastic force that the horizontal punch die of slope driving the overcomes spring motion of turning right, horizontal punch die is connected with fixing slide unit by oat tail groove structure, horizontal drift passes copper sheathing (copper sheathing is on time grease-added), guarantee its motion process steadily and guiding precisely.When horizontal punch die is turned right motion during 75mm, calculate the patrix 130mm that down moves by Pythagorean theorem, control the locus of patrix and horizontal punch die well, make punch die can act on simultaneously the hole of horizontal level and upright position, reach one time punching molded effect.The shape that the punch shape of punch die is made when tangent with pipe is the same, pipe unbalance stress in the time of can avoiding punching and deforming.Referring to figure crooked pipe antarafacial hole one-shot forming apparatus (done state can referring to Fig. 2), the waste material that sweeps away drops to waste material collection device by the feed opening in counterdie, and punching press is completed, patrix up, spring reset, a punching press is completed, artificial blanking.

To the above-mentioned explanation of the disclosed embodiments, make this area professional and technical personnel can realize or use the utility model.Multiple modification to these embodiment will be apparent concerning those skilled in the art, and General Principle as defined herein can be in the situation that do not break away from spirit or scope of the present utility model, realization in other embodiments.Therefore, the utility model will can not be restricted to these embodiment shown in this article, but will meet the widest scope consistent with principle disclosed herein and features of novelty.
