Abstract

The utility model relates to a multi-punch punching-riveting mold. The multi-punch punching-riveting mold comprises an upper mold plate, a lower mold plate, a bottom mold and n independent punch components, wherein the upper mold plate is matched with the lower mold plate through a guide sleeve and a guide pole so as to enable the upper mold plate to smoothly slide up and down along the guide pole, the bottom mold is fixed on the lower mold plate, and the n independent punch components are respectively fixed at the different setting parts of the upper mold plate; and each independent punch component mainly comprises a punch fixing block and a punch, the punches are matched and connected with through holes on the punch fixing blocks through cylinders at the tail ends of the punches, mounting threaded holes are formed on the punch fixing blocks, and the punch fixing blocks are fixedly connected with the upper mold plate through mounting bolts. The multi-punch punching-riveting mold is provided with a plurality of independent punch components, thus when the multi-punch punching-riveting mold is matched with a pressing machine for use, punching-riveting operation of a plurality of working positions can be completed by clamping once, so that the multi-punch punching-riveting mold can not only improve the production efficiency but also reduce the working strength of a worker; and the independent punch components are independent mutually, convenient and flexible to use and strong in applicability, the bottom mold can be positioned quickly, the precision is ensured, and the multi-punch punching-riveting mold is further conductive to quality requirements of large-batch production.

Description

Many drifts are towards the riveting mould

Technical field

The utility model relates to a kind of towards riveting equipment, and particularly a kind of many drifts that are used for the production of vehicular electrical appliance parts are towards the riveting mould.

Background technology

In the production of vehicular electrical appliance parts, usually need that the working pressure machine dashes, rivet clasp is fixed or encapsulation, existing pattern is generally single drift; There is not special-purpose mould; Promptly directly drift is installed on the depression bar of forcing press, can only dashes, station of riveting at every turn, a plurality of as having on the workpiece towards the riveter position; Then need continuous conversion station to repeat towards riveting, efficient is low, labour intensity is big.

Summary of the invention

The purpose of the utility model is to provide high, easy to operate, the economical and practical many drifts of a kind of production efficiency towards the riveting mould, to solve the problems referred to above that prior art exists.

The technical scheme that the utility model is taked is: a kind of many drifts are towards the riveting mould; Said mould comprises cope match-plate pattern, lower bolster, bed die and n independent punch-head assembly; Said cope match-plate pattern cooperates with lower bolster through guide pin bushing and guide pillar; Cope match-plate pattern can be slided up and down along guide pillar stably, and said bed die is fixed on the lower bolster, and n independent punch-head assembly is separately fixed at the different set position of cope match-plate pattern through construction bolt; The value of said n is the arbitrary integer between 2 ~ 20.

Its further technical scheme is: said independent punch-head assembly mainly is made up of drift fixed block and drift; Drift is connected through the cylinder of tail end and the through hole on the drift fixed block; Have the installation screwed hole on the drift fixed block, the drift fixed block is fixedly connected with cope match-plate pattern through construction bolt.

Said cope match-plate pattern has the through hole that is used to pass construction bolt at the position that independent punch-head assembly is installed, and leaves the adjustment space between through hole and the construction bolt.

Have the location nib that cooperates with workpiece on the said bed die.

Compared with prior art, drift has following beneficial effect towards the riveting mould more than the utility model:

Since the utility model more than drift be provided with a plurality of independent punch-head assemblies towards the riveting mould; When cooperating forcing press to use; A clamping can be accomplished the riveting of dashing of a plurality of stations, the work that needed multiple working procedure to accomplish originally, the existing one procedure that only needs; Not only improve production efficiency, and reduced the intensity of workman's work;

Since more than the utility model drift separate towards riveting mould independence punch-head assembly, regulate arbitrarily or change according to the situation of workpiece, easy to use flexibly, applicability is strong;

Since more than the utility model drift be provided with the bed die that is used to make the workpiece location towards the riveting mould, during production workpiece is placed on the bed die and can locatees fast, thereby can guarantee towards the precision at riveting position the quality requirement that helps producing in enormous quantities.

Below, in conjunction with accompanying drawing and embodiment the technical characterictic of drift more than the utility model towards the riveting mould is further described.

The specific embodiment

A kind of many drifts are towards the riveting mould; Said mould comprises cope match-plate pattern 5, lower bolster 1, bed die 9 and 2 independent punch-head assemblies 4; Said cope match-plate pattern 5 cooperates with lower bolster 1 through guide pin bushing 3 and guide pillar 2; Cope match-plate pattern can be slided up and down along guide pillar stably, and said bed die 9 is fixed on the lower bolster 1, and 2 independent punch-head assemblies 4 are separately fixed at the different set position of cope match-plate pattern through construction bolt 8.

Said independent punch-head assembly 4 mainly is made up of drift fixed block 41 and drift 42; The cylinder of drift through tail end is connected with through hole employing interference fit on the drift fixed block; Have the installation screwed hole on the drift fixed block, drift fixed block 41 is fixedly connected with cope match-plate pattern 5 through construction bolt 8.

Said cope match-plate pattern 5 has the through hole 51 that is used to pass construction bolt at the position that independent punch-head assembly is installed, and leaves adjustment space 511 between through hole and the construction bolt 8.

Have the location nib 91 that cooperates with workpiece on the said bed die 9.

As the conversion of the foregoing description, the number that is installed in the independent punch-head assembly on the cope match-plate pattern can be provided with according to the station of workpiece needs towards riveting, is generally the arbitrary integer between 2 ~ 20; Said bed die is different because of workpiece, can be equipped with the bed die of different location nib according to the shape of different workpieces.
