Second kind is to optimize the mould design, through increasing groove design in cutting edge portion, accumulates gradually at the mould concave part from die-cut process, making to dash to consider to be worth doing, stops metal fillings attached on the mould.This mode can alleviate dashes the influence that bits use mould, but can not fundamentally solve the problem of dashing the bits bonding.
A kind of " cleanable press machine " disclosed on the Chinese patent document; The day for announcing is on August 1st, 2007, and Granted publication number is CN 101007449A, and it is provided with the guider that links to each other with drift on mould; Behind the punching molding certain hour; Drift is come out to clean from decompressor lira along guider, wait the cleaning finish after, again drift is resetted along guider.This scheme can be removed loaded down with trivial details mould from and disassembled work; Help prolonging the service life of mould, but its cleaning procedure remains the cleaning of clearance-type, needs shutdown operation; Therefore can't avoid dashing the bonding of bits and the reduction of product percent of pass fully, and production efficiency is produced adverse influence.
Summary of the invention
The present invention is when overcoming that the die-cut technology of existing mould is existing dashes bits and be prone to bonding, mould cleaning expense and the low problem of production efficiency, and a kind of device of avoiding dashing the bits bonding and realizing continuous cutting is provided
To achieve these goals; The present invention adopts following technical scheme: a kind of device of avoiding diel to dash the bits bonding; Be applicable to the die-cut of coiled material, comprise two cylinders that the coiled material that is positioned at mould is sent into a side, is close to and arranges up and down each other, said cylinder comprises the oil drum of closed at both ends and is located at the resilient oil seepage layer in the oil drum outside; The periphery of oil drum is provided with some equally distributed oil seepage holes, and an end of oil drum is connected with the punching oil induction system through pipeline.
Two cylinders up and down in the device that diel dashes bits bondings be used to liquidate upper and lower surface coating one deck punching oil of writing that surpasses all the others material of avoiding of the present invention; Can greatly increase the greasy property of coiled material when punching molding; Avoid the generation of dashing bits that when dryness is die-cut, is easy to occur, help improving die-cut quality.Especially, punching oil can play the effect of cold oil, adds its good lubricating property; Even make the coiled material that is coated with punching oil when punching molding, produce the bits that dash of trace, sintering phenomenon can not appear, and wherein major part can be fallen towards bits automatically; And a small amount of absorption affinity of considering to be worth doing owing to punching oil of dashing is adsorbed on the mould; And the vibrations when die-cut fall, thereby can avoid mould is carried out downtime, have improved production efficiency effectively.In addition, it is die-cut that the coiled material that is coated with punching oil makes that also mould is easy to, thus the service life that helps improving mould, the grinding number of times of minimizing cutting edge.Compare with the spray mode of cooling fluid common in the general machine cut processing; Punching oil among the present invention is from oil drum, progressively to be penetrated into the oil seepage layer outer surface; And then coat the upper and lower surfaces of coiled material equably through two cylinders; Thereby both can equably punching oil have been coated the upper and lower surfaces of whole coiled material, and can reduce the use amount of punching oil again significantly, reduce production costs.Especially, punching oil can adopt high volatile volatile, low viscous essence to dash oil, the coiled material surface thin and uniformly oil film can volatilize voluntarily and leave no trace, therefore, the product after die-cut can avoid cleaning, and has reduced manufacturing procedure.
