Description

The hole machined cutting die device that a kind of anti-displacement is fixing

Technical field

This utility model relates to punch press plant equipment, particularly relates to a kind of for capacitance plate hole machined punch press machine The hole machined cutting die device that the anti-displacement of tool equipment is fixing.

Background technology

Punching apparatus for either simplex journey sheet metal small-sized, medium-sized and the blanking of high-sped progressive die part, punching, The work such as warpage, molding, for the continuous punching operation that high accuracy, high yield and stability requirement are high.Cutting die In cross cutting industry, belong to the more commonly used product, be generally used for stamping out the shape of required die cutting product. Cutting die is also the abbreviation of cutter, mould, and cutter is mechanical bit, and mould is machine die, such as: bender Mould, punching and shearing machine mould etc..Conventional knives molding work is to draw with pencil or ball pen on cutting die plate, Being sawed by sawing machine afterwards, will form dislocation and produce error during movement, process velocity is slow.

This case, can not during punching it is important to note that lack Elastic plastic-rubber structure on traditional cutting die head Have the effect that buffering is fixing to hole periphery, product fraction defective is high.Therefore, for the above, need existing Technology is had reasonably to improve.

Utility model content

For disadvantages described above, this utility model provides one can be fixed capacitance plate, punching press time to electric capacity There is buffering effect hole machined position, advantageously reduces the hole machined cutting die dress that the anti-displacement of product undesirable condition is fixing Put, to solve many deficiencies of prior art.

For achieving the above object, this utility model is by the following technical solutions:

The hole machined cutting die device that a kind of anti-displacement is fixing, is made up of main shaft, cutting die, Elastic plastic-rubber die sleeve, Described front-end of spindle fixed installation cutting die, in this main shaft and cutting die fixedly embedded Elastic plastic-rubber die sleeve centre bore, Described Elastic plastic-rubber die sleeve outer end is with the plastic cement die head of cone shape；Meanwhile, described Elastic plastic-rubber die sleeve Centre bore is divided into upper and lower two sections, and hypomere central hole therein is in the center of plastic cement die head and its aperture Cross-sectional diameter equal to cutting die.

The aperture in described upper section central hole is equal to the cross-sectional diameter of main shaft；The cutting die of main shaft 1 is in Elastic plastic-rubber Slide in die sleeve.

Having the beneficial effect that by treating of the hole machined cutting die device that anti-displacement described in the utility model is fixing The capacitance plate alignment position in processing hole is placed on the lower section of cutting die, starts machine tool chief axis and declines, the bullet in cutting die front Property plastic cement die sleeve elder generation hand capacity screen punching position the most fixing, the cutter head elasticity of compression plastic cement die sleeve of main shaft, cutter Stamping hole, main shaft cutter head rises, and Elastic plastic-rubber die sleeve resilience, cutter head retracts to, in Elastic plastic-rubber die sleeve, enter Row subsequent work, has buffering effect to electric capacity hole machined position during this structure punching press, reduce product undesirable condition.
