Description

Connecting rod trimming, punching, the correction progressive die

Technical field

The present invention relates to a kind of progressive die, particularly relate to a kind of connecting rod trimming, punching, the correction progressive die.

Background technology

Connecting rod is part necessary on all kinds of diesel engine, and is one of most important part, and the production process of connecting rod is very complicated, and operation is many, and the cycle is long, requires strict.The need of production of connecting rod part passes through forging, heat treatment, machined, the operations such as fine finishining.In forging process, trimming, punching, correction are separately carried out, and operation is many, and the cycle is long, also need to overpay frock, and punching also needs to take mach method sometimes, and production cost is high, and product quality not easily ensures.

Summary of the invention

Object of the present invention is just to provide a kind of connecting rod trimming, punching, the correction progressive die, can solve above-mentioned prior art Problems existing completely.

Object of the present invention is realized by following technical proposals:

A kind of connecting rod trimming, punching, the correction progressive die, comprise upper die and lower die, patrix is provided with trimming punch, on counterdie, correspondence offers blanking die cavity, patrix is also provided with correction drift, on counterdie, correspondence offers correction die cavity, is provided with pierce punch in correction drift bottom surface, corrects correspondence in die cavity and offers punching.

Further, correct die cavity lower than blanking die cavity, sliding plate is set below the blanking die cavity of counterdie and is connected to correction die cavity.

This structure is conducive to the continuity of processing, and the workpiece that trimming completes drops on sliding plate from blanking die cavity, slips into correction die cavity along sliding plate, carries out correcting and punching operation.

Further, arrange guide pillar in correction die cavity surrounding, guide pillar upper end is stretched in the guide pillar hole correcting and drift is offered.

Guide pillar can ensure the accuracy corrected, and avoids correcting drift sideslip.

Further, described counterdie has calibration template and die holder, die holder is arranged four guide pillars, calibration template is socketed on guide pillar, and arranges elastic component between calibration template and die holder, calibration template is offered correction die cavity.

Further, described elastic component is for correcting rubber or spring.

Compared with prior art, beneficial effect of the present invention is: structure is simple, reasonable in design, after adopting this progressive die, trimming, punching, correction three process can be completed in one pair of frock, ensure that product quality, shorten the production cycle, reduce production cost.

Accompanying drawing explanation

Fig. 1 is front view of the present invention;

Fig. 2 is left view of the present invention;

Fig. 3 is after the present invention removes patrix, the top view of counterdie.

Detailed description of the invention

Below in conjunction with specific embodiments and the drawings, the present invention is further illustrated.

Shown in Fig. 1, Fig. 2 and Fig. 3, a kind of connecting rod trimming, punching, the correction progressive die, comprise patrix 1 and counterdie 2, patrix 1 is provided with trimming punch 3, on counterdie 2, correspondence offers blanking die cavity 4, patrix 1 is also provided with and corrects drift 5, and on counterdie 2, correspondence is offered and corrected die cavity 6, be provided with pierce punch 7 in correction drift 5 bottom surface, correct correspondence in die cavity 6 and offer punching 8.

Correct die cavity 6 lower than blanking die cavity 4, sliding plate 9 is set below the blanking die cavity 4 of counterdie 2 and is connected to correction die cavity 6.

Described counterdie 2 there are calibration template 21 and die holder 22, die holder 22 is arranged four guide pillars 23, calibration template 21 is socketed on guide pillar 23, and arrange between calibration template 21 and die holder 22 and correct rubber or spring 24, calibration template 21 is offered and corrects die cavity 6, guide pillar 23 is positioned at the surrounding correcting die cavity 6, and guide pillar 23 upper end is stretched in the guide pillar hole correcting and drift 5 is offered.

Operationally, foundry goods is placed on blanking die cavity 4, trimming punch 3 is pushed down into blanking die cavity 4, and foundry goods is obtained the workpiece of connecting rod shape by trimming, and workpiece drops on sliding plate 9, and slip into correction die cavity 6 along sliding plate 9, correct drift 5 to press down, pierce punch 7 first contacts workpiece, goes out circular hole at workpiece two ends, then correct drift 5 to continue to be pushed down into correction die cavity 6, workpiece is corrected.After adopting this progressive die, trimming, punching, correction three process can be completed in one pair of frock, ensure that product quality, shorten the production cycle, reduce production cost.

The foregoing is only preferred embodiment of the present invention, not in order to limit the present invention, all any amendments done within the spirit and principles in the present invention, equivalent replacement and improvement etc., all should be included within protection scope of the present invention.
