Description
Technical field
The utility model is related to a kind of diel, more particularly, to it is a kind of can be with the diel of automatically removing burr.
Background technology
Common Sheet Metal Forming Technology is inevitably all jagged, although impulse- free robustness Sheet Metal Forming Technology, fine blanking technology are succeeded in developing, but
So far the stage of popularization is not yet entered.So far, various sheet metal stamping process, metallic plate punching process is referred mainly to, is belonged to greatly
Jagged punching press, but some products or product are local because specific demand does not allow the presence of burr, at this moment stamping parts deburring
It is exactly essential process.Although current industrial stamping parts debarring process has many kinds, but mostly using machinery
Burr removing method.
At present, the species of existing machinery debarring process mainly has following several：1st, manual debarring process：Manually make
The dirt of stamping parts rust and burr are removed with instruments such as wire brush, file, scraper, emery wheels.Because labor intensity is big, efficiency is low, cost is high,
It is only applicable to the stamping parts of Single unit job lot production.2nd, roller debarring process：Stamping parts is to forge through roller debarring process
Part develops what is come on the basis of having abrasive roller removing surface technique, and the stamping parts of deburring is intended to before barreling with selecting in advance
Abrasive material be fitted into be sealed in roller in proportion, roller revolution makes stamping parts and abrasive material free to tumble in roller, is touched by mutual
Hit or burr and surface rusty stain on abrasive cleaning workpiece shear surface.Roller Trimming is applied to small-medium size and expects thick rush
Casting die.Stamping parts is mounted in free to tumble in roller with abrasive mixed during because of barreling, and stamping is easily hit and occurs damaging or deform.Cause
This, material is thin and stamping poor rigidity that size is big, and impulsive force is big, deforms unavoidably during barreling.3rd, vibration finishing deburring：Vibration finishing
Deburring is a kind of vibration grinding process, and principle is to load the stamping parts of deburring and the abrasive material prepared by a certain percentage jointly
Appropriate additive is reinjected in container, by the periodic vibration of container, makes stamping parts and stamping parts, between stamping parts and abrasive material
Mutually extruding, grinding, so as to reach light decorations surface, deburring, periphery chamfered edge purpose.This method is only applicable to material thickness greatly,
The flat-type stamping parts of good rigidity, but it is inefficient, and running noise is often exceeded.4th, it is ground deburring：With emery wheel or abrasive band pair
Stamping parts carries out flat surface grinding, and usually used has sbrasive belt grinding flash trimmer, transmission belt grinding flash trimmer etc..Due to electromagnetism
Suction is relevant with the size of workpiece and the size of thickness, and undersized then suction deficiency, excessively thin, the deformation to work may be serious,
Work is easy to fly out during grinding, thus is suitable for thick to material>2.5mm and thicker steel stamping part deburring.5th, unhairing is sprayed
Thorn：Injection deburring its principle is the injecting substances that will be prepared, sand, bead, shot, the abrasive particle of such as designated size
Deng, nozzle is transported to compressed air by pipeline, the workpiece surface being fixed in container on special stand is ejected into from nozzle,
The dirty, burr that become rusty using blasting materials to working surface carries out high speed impact cutting, reaches the purpose to workpiece deburring.But the party
Method is less efficient, can only process several every time, clamping time length, so being not suitable for going for the small size stamping parts of production in enormous quantities
Burr.
How a variety of drawbacks of several debarring process in summary, improve efficiency and production capacity, reduce bad risk and
The subject matter that product cost needs to solve into our current debarring process.
Utility model content
The defects of the purpose of this utility model is to overcome prior art, there is provided there is one kind the automatic backhand of continuous punching to go

Template pushes down product edge when closing.
Preferably, formed with the salient angle being consistent with product edge in the lower mould insert.
Preferably, the salient angle is formed on the upper surface of the lower mould insert, and protrudes the lower mould insert surface extremely
Few 0.5mm.
Preferably, the salient angle is C-shaped angle.
Preferably, the salient angle has a start line, and the distance that the outside of the start line and product is intermarginal is at least
0.1mm。
Preferably, the lower surface of the middle mould insert is plane.
Preferably, in addition to up and down upper bolster, cope plate and the die shoe being distributed.
Preferably, upper die plate is provided between the upper bolster and cope plate, is set between the cope plate and middle template
Middle die-cushion plate is equipped with, lower mold backing plate is provided between the lower template and die shoe.
Preferably, the C-shaped angle is by protruding between two projections and two projections of the upper end face of lower mould insert
The part upper end face composition of lower mould insert.
Preferably, the start line is perpendicular to lower template surface and by the lower mould insert between raised and two projections
The intersecting point of part upper end face straight line.
Compared with prior art, the utility model, can be even by increasing insert respectively in middle template and lower template
Cut-out is completed inside continuous mould and claps the technique of burr one, realizes the punching carrot-free requirement in edge, improves efficiency and production capacity, drop
Low bad risk and product cost, convenient disassembly, strong applicability.
