Two guide bars and constitute sliding fit, rectify and install nitrogen spring between terrace die and the slider, the end of drift fixed mounting at a guide bar punches a hole. This compound die sets up to be equipped with and only need once, just can accomplish in proper order and punch a hole, cut edge, proofread and correct the process the bloated connecting rod clamping that breaks of automobile, lightens operation workman intensity of labour by a wide margin, improves production efficiency.
Description
Technical field
The utility model belong to auto parts and components forging process equipment field, be specifically related to a kind of fractured connecting rod punching forgings, trimming, calibrating combined mold erection standby.
Background technology
Automobile fractured connecting rod is one of key components and parts on automobile, and traditional processing automobile fractured connecting rod forging production process, is after forging is shaping, adopts continuous mould bases to carry out the technical process of punching, trimming, correction.Adopt the defect that there is several aspect in the said equipment and technical process: (1) adopt multiple step format punching, trimming technological process time, the distortion of automobile fractured connecting rod is larger, and after trimming, the distortion of forging is also comparatively large, does not meet the required precision of following process; (2) traditional processing method, operator's labour intensity is large, and production efficiency is low; (3) service life to the high connecting rod mould for forging of deformation requirements is reduced.
Utility model content
The purpose of this utility model be to provide fractured connecting rod punching forgings, trimming, calibrating combined mold erection standby, this compound die carrier equipment only needs to automobile fractured connecting rod clamping once, just can complete punching, trimming, correcting process successively, significantly alleviate operator's labour intensity, enhance productivity.
In order to realize above-mentioned technical characteristic, the purpose of this utility model is achieved in that fractured connecting rod punching forgings, trimming, calibrating combined mold erection is standby, it comprises upper bolster, upper bolster is fixedly mounted on the slide block of forcing press, die shoe is fixedly mounted on the workbench of forcing press, trimming punch is fixedly mounted on die shoe by holding screw, the edge of trimming punch is provided with stripper, upper bolster is provided with correction punch, the both sides correcting punch are installed with two trim dies by tight fixed bolt, described correction punch is through a guide post and No. two guide posts and form and be slidably matched, correct between punch and slide block and nitrogen spring is installed, pierce punch is fixedly mounted on the end of a guide post.
Described trimming punch is processed with punching hole.
Described upper bolster moves up and down along lead and coordinates with die shoe.
Described No. two guide post installation sites can at chute internal adjustment, to adapt to the connecting rod forging of different centre-to-centre spacing.
The utility model has following beneficial effect:
1, when carrying out punching press to connecting rod forging, first using nitrogen spring to be compressed by trimming punch and correction punch by connecting rod forging, then carrying out stamping press, thus ensure that the distortion of forging in punching and trimming process is less.
2, in clamping process, only need once just can complete the operations such as punching, trimming, correction to connecting rod forging clamping simultaneously, thus effectively alleviate the labour intensity of operator, improve production efficiency.
3, can be adjusted the installation site of No. two guide posts easily by chute, thus improve its adaptability, the punch process requirement of different model connecting rod forging can be met, improve adaptability.
4, extending mould volume service life, because Pressing Deformation is comparatively large, by adopting the punching die frame equipment of combined type to improve punching precision, effectively extending the service life of the higher connecting rod mould for forging of deformation requirements.
Accompanying drawing explanation
Below in conjunction with drawings and Examples, the utility model is described in further detail.
Fig. 1 is the utility model overall structure schematic diagram.
In figure: slide block 1, guide post 2, No. two guide posts 3, nitrogen spring 4, upper bolster 5, die 6, correction punch 7, trimming punch 8, die shoe 9, workbench 10, pierce punch 11, lead 12, stripper 13, punching hole 14, holding screw 15, tight fixed bolt 16, chute 17, connecting rod forging 18.
Detailed description of the invention
Below in conjunction with accompanying drawing, embodiment of the present utility model is described further.
As shown in Figure 1, fractured connecting rod punching forgings, trimming, calibrating combined mold erection is standby, it comprises upper bolster 5, upper bolster 5 is fixedly mounted on the slide block 1 of forcing press, die shoe 9 is fixedly mounted on the workbench 10 of forcing press, trimming punch 8 is fixedly mounted on die shoe 9 by holding screw 15, the edge of trimming punch 8 is provided with stripper 13, upper bolster 5 is provided with and corrects punch 7, the both sides correcting punch 7 are installed with two trim dies 6 by tight fixed bolt 16, described correction punch 7 is through a guide post 2 and No. two guide posts 3 and form and be slidably matched, correct between punch 7 and slide block 1 and nitrogen spring 4 is installed, pierce punch 11 is fixedly mounted on the end of a guide post 2.
Further, described trimming punch 8 is processed with punching hole 14.The punching press in hole on connecting rod forging 18 is realized by coordinating between punching hole 14 with pierce punch 11.
Further, described upper bolster 5 moves up and down along lead 12 and coordinates with die shoe 9.Make correction punch 7 run thus match with trimming punch 8 downwards by the movement of upper bolster 5, clamping and positioning is carried out to connecting rod forging 18.
Further, described No. two guide post 3 installation sites can at chute 17 internal adjustment, to adapt to the connecting rod forging 18 of different centre-to-centre spacing.By No. two guide posts 3 moving thus making its centre-to-centre spacing produce change at chute 17 interior location, adapt to different connecting rod forging 18.
The course of work of the present utility model and principle are:
1, this framework equipment adopts closed type single point press, and upper bolster 5 is arranged on press ram 1, and die shoe 9 is arranged on press bench 10, and slide block is when top dead centre, and connecting rod forging is placed on trimming punch 8.
2, when press ram moves downward, correct punch 7 and contact with connecting rod forging 18 and compressed by nitrogen spring 4.
3, press ram continues to move downward, and nitrogen spring 4 is compressed, and correct punch 7 and moved upward by a guide post 2 and No. two guide posts 3, pierce punch 11 contacts with forging and gone out by connecting rod forging gross weight.
4, press ram continues to move downward until lower dead center, and trim die 6 contacts with forging flash and by cutting burrs.
5, press ram returns top dead centre stopping, and connecting rod forging rests on trimming punch 8, and overlap rests on stripper 13, and gross weight stops in die shoe 1, takes out connecting rod forging, overlap, gross weight.
By repeating above-mentioned step, then carry out the punching press of next connecting rod forging.
Above-described embodiment is used for explaining and the utility model is described; instead of the utility model is limited; in the protection domain of spirit of the present utility model and claim, any amendment make the utility model and change, all fall into protection domain of the present utility model.
