Abstract
A kind of blanking die processing trapezoidal contact on punch press, it comprises the upper and lower template be assembled on guide pillar, it is characterized in that upper and lower template is fixedly connected with the upper and lower zigzag cutting knife of stepped tooth respectively, upper and lower zigzag cutting knife shape is identical, tangentially relative, and upper and lower zigzag cutting knife mutual dislocation realizes incision mutually; Stripper and discharging rubber is connected by movable bolt at the side of upper and lower zigzag cutting knife.The utility model is disposable cuts the trapezoidal contact of multi-disc, and efficiency improves, and does not stay rim charge, saves material, and improves equipment benefit.
Description
Technical field
The utility model relates to a kind of punch press blanking die, particularly a kind of blanking die processing trapezoidal contact on punch press.
Background technology
The trapezoidal part of sheet for low-voltage electrical apparatus electrical contact, generally adopts the blanking die of matched molds form to produce when actual production, and 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 the trapezoidal contact part of polylith, improve effect.
For achieving the above object, the utility model adopts following technical scheme: it comprises the upper and lower template be assembled on guide pillar, it is characterized in that: upper and lower template is fixedly connected with the upper and lower zigzag cutting knife of stepped tooth respectively, upper and lower zigzag cutting knife shape is identical, tangentially relative, and upper and lower zigzag cutting knife mutual dislocation realizes incision mutually; Stripper and discharging rubber is connected by movable bolt at the side of upper and lower zigzag cutting knife.
Effect of the present utility model: 1. disposablely cut the trapezoidal contact of multi-disc, efficiency improves.2. do not stay rim charge, save material, improve equipment benefit.
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: cope match-plate pattern 1 is assembled on guide pillar 2, lower bolster 3 is assembled on guide pin bushing, upper and lower template 1,3 is fixedly connected with upper and lower zigzag cutting knife 1-1,3-1 of stepped tooth respectively by bolt 7, upper and lower zigzag cutting knife shape is identical, tangentially relative, and upper and lower zigzag cutting knife 1-1,3-1 mutual dislocation realizes incision mutually; Upper and lower cutting knife 1-1,3-1 are upper is equipped with spacer 4 by alignment pin 5;
At the side of upper and lower zigzag cutting knife 1-1,3-1, namely upper and lower template 1,3 is connected with stripper 1-3,3-3 and discharging rubber 1-2,3-2 by movable bolt 6.
Using method: by the material strip cut in advance, along the direction parallel with sawtooth cutting knife, is placed on the fixing position of spacer.Cutting knife falls, and can cut the contact that next row is trapezoidal.
