Abstract

A kind of multitool is without the contact blanking die of rim charge, it comprises upper and lower template, it is characterized in that upper and lower template is all fixedly connected with left and right cutter holder, multi-disc upper cutter is bolted between the left and right cutter holder of cope match-plate pattern, multi-disc lower cutter is bolted between the left and right cutter holder of lower bolster, between each upper cutter, each lower cutter, edge bearing is placed at interval, and upper cutter is tangential tangentially relative with lower cutter, and upper and lower cutting knife mutual dislocation realizes incision mutually; At the knife-edge part of upper and lower cutting knife, upper and lower stripper is set.The utility model is simple and reliable for structure, and cutting knife can be changed, and precision is high, and operating efficiency is high, can not stay rim charge and once fall polylith contact.

Description

A kind of multitool is without the contact blanking die of rim charge

Technical field

The utility model relates to multitool that a kind of punch press blanking die, particularly a kind of punch press the are applied contact blanking die without rim charge.

Background technology

For the flat parts of low-voltage electrical apparatus electrical contact, generally adopt the blanking die of matched molds form to produce when actual production, this mould production efficiency is low.If adopt many formpistons to produce, although can enhance productivity, Mould Machining difficulty is large, and needs between contact to leave certain rim charge, and this rim charge is many as waste disposal, wastes a large amount of contact materials.

Utility model content

The purpose of this utility model is for the problems referred to above, provides a kind of multitool blanking die that can not stay rim charge.Rim charge can not be stayed and once fall polylith contact, improving effect.

For achieving the above object, the utility model adopts following technical proposals: it comprises upper and lower template, it is characterized in that: upper and lower template is all fixedly connected with left and right cutter holder, multi-disc upper cutter is bolted between the left and right cutter holder of cope match-plate pattern, multi-disc lower cutter is bolted between the left and right cutter holder of lower bolster, between each upper cutter, each lower cutter, edge bearing is placed at interval, and upper cutter is tangential tangentially relative with lower cutter, and upper and lower cutting knife mutual dislocation realizes incision mutually; At the knife-edge part of upper and lower cutting knife, upper and lower stripper is set.

The beneficial effects of the utility model: 1. simple and reliable for structure, cutting knife can be changed, and precision is high.2. operating efficiency is high, can not stay rim charge and once fall polylith contact.

Accompanying drawing explanation

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

Fig. 2 is A-A sectional view of Fig. 1.

Detailed description of the invention

See Fig. 1,2, concrete structure is as follows: upper and lower template 1-7,2-7 are assembled on the guide pile of punch press by prior art, and upper and lower template 1-7,2-7 are fixedly connected with left and right cutter holder 1-3.1,1-3.2 respectively, 2-3.1,2-3.2; Multi-disc upper cutter 1-5 is connected by bolt 1-4 between the left and right cutter holder of cope match-plate pattern 1-7, between the left and right cutter holder of lower bolster 2-7, connect multi-disc lower cutter 2-5 by bolt 2-4, the left and right cutter holder of upper and lower template is fixed in upper and lower template by bolt 9 and pin 8; Between each upper cutter 1-5, each lower cutter 2-5, edge bearing 1-6,2-6 are placed in each interval, and upper cutter is tangential tangentially relative with lower cutter, and upper and lower cutting knife mutual dislocation realizes incision mutually; Upper and lower stripper 1-1,2-1 of foamed elastic are respectively set at the knife-edge part of upper and lower cutting knife.

Using method: first contact plate is placed on position suitable on stripper by the direction vertical with cutting knife, cuts many contact material strips, then placed side by side on stripper by the direction vertical with cutting knife for a little material strips cut, incision.The contact cut can be obtained.On the drift that upper and lower template 1-7,2-7 are contained in punch press respectively and die holder.The elasticity stripper be fixed between cutting knife is used to draw off the workpiece cut.
