Abstract
The invention discloses a height adjustable burr-free punch. The height adjustable burr-free punch comprises a punch base and is characterized by also comprising a bolt, a nut and a blade; a plurality of threaded holes which are for the bolt to penetrate are formed in the middle of the punch base; the threaded holes are formed in the same line; the blade is arranged at the top of the punch; a long-strip-shaped opening is formed in the blade above the threaded holes; the bolt which can penetrate the long-strip-shaped opening is fixed through the nut; bilateral sides of the machining end of the blade are designed into fillets; the semi-diameter of the fillets is from 0.04 cm to 0.07 cm. The height adjustable burr-free punch has the advantages of solving the problems that, in the prior art, the blade height of the punch cannot be adjusted, machining requirements of products made of different materials cannot be satisfied, burrs are easy to be formed on fracture surfaces of products stamped through the punch, and product quality is reduced and being convenient to use, adjustable in height, convenient to install and detach and long in service life.
Description
Technical field
The present invention relates to a kind of drift, particularly relate to a kind of adjustable for height without burr drift.
Background technology
Current drift stamping products easily forms burr on the product plane of disruption, has reduced the quality of product, can not meet the accurately machined requirement of some products.Current blade can only be fixed on a height simultaneously, and highly non-adjustable, the stroke of cutting cannot change, and can not meet the cutting of various unlike material products.The punch holder of drift and blade adopt one-body molded in addition, after the long-time use of blade, because of wearing and tearing, consume gradually, final blade can not be used because damage is scrapped, because blade and punch holder can not be separated, whole like this drift has also just been scrapped, and need to again change drift, use cost improves greatly, has increased the weight of the burden of enterprise.
Summary of the invention
Non-adjustable in order to solve in prior art the blade height of drift, can not meet various unlike material product processing requests, and drift stamping products, easily on the product plane of disruption, form burr, reduced the problem of product quality, the invention provides a kind of, easy to use, highly adjustable, easy installation and removal, service life, longer height was adjustable without burr drift.
In order to address the above problem, the technical solution used in the present invention is:
A kind of without the adjustable drift of burr height, comprise punch holder, it is characterized in that: also comprise bolt, nut and blade, at punch holder middle part, be provided with some for the screwed hole through bolt, described screwed hole is positioned at same straight line, top in punch holder is provided with blade, on described blade, offer the strip opening that is positioned at screwed hole top, described bolt can pass strip opening, and utilize nut to fix, fillet is arranged in the processing end both sides of described blade, and the radius of described fillet is 0.04cm-0.07cm.
Aforesaid a kind of adjustable for height without burr drift, it is characterized in that: the radius of described fillet is 0.05cm.
Aforesaid a kind of adjustable for height without burr drift, it is characterized in that: described strip opening two ends are arc tips.
The invention has the beneficial effects as follows: the present invention is adjustable for height without burr drift, at punch holder middle part, be provided with some for the screwed hole through bolt, on described blade, offer the strip opening that is positioned at screwed hole top, described bolt can pass strip opening, and utilizes nut to fix.By screw bolt and nut, coordinate blade quick release like this, be convenient to reinstall and keep in repair, effectively reduce cost, avoided the waste that punch holder is unnecessary.The present invention can be arranged at bolt the optional position of strip opening in addition, and utilizes nut to fix, and the height that blade is arranged in punch holder so just can regulate, applied widely, easy to use.Fillet is arranged in the processing end both sides of blade of the present invention, and the radius of described fillet is 0.05cm.By fillet, product is carried out to punching press, the product tear face smoother after punching press, product quality is higher, can meet the needs that following process is used.
Accompanying drawing explanation
Fig. 1 is that the present invention is adjustable for height without burr punch structure schematic diagram.
The specific embodiment
Below in conjunction with accompanying drawing, the invention will be further described.
As shown in Figure 1, a kind of adjustable for height without burr drift, comprise punch holder 1, bolt, nut 4 and blade 2, at punch holder 1 middle part, be provided with some for the screwed hole through bolt, described screwed hole is positioned at same straight line, at the top of punch holder 1, be provided with blade 2, on described blade 2, offer the strip opening 3 that is positioned at screwed hole top, described bolt can pass strip opening 3, and utilize nut 4 fixing, fillet 6 is arranged in the processing end both sides of described blade 3, and the radius of described fillet 6 is 0.04cm-0.07cm.Described strip opening 3 two ends are arc tips 5.
The present invention is adjustable for height without burr drift, at punch holder 1 middle part, be provided with some for the screwed hole through bolt, on described blade 2, offer the strip opening 3 that is positioned at screwed hole top, described bolt can pass strip opening 3, and utilizes nut 4 fixing.By screw bolt and nut 4, coordinate blade 2 quick releases like this, be convenient to reinstall and keep in repair, effectively reduce cost, avoided the unnecessary waste of punch holder 1.The present invention can be arranged at bolt the optional position of strip opening 3 in addition, and utilizes nut 4 fixing, and the height that blade 2 is arranged in punch holder 1 so just can regulate, applied widely, easy to use.Strip opening of the present invention 3 two ends are arc tips 5 in addition, are convenient to like this bolt and take out from arc tips 5, have improved dismounting speed.Fillet 5 is arranged in the processing end both sides of blade 2 of the present invention, and the radius of described fillet 5 is 0.05cm.By 6 pairs of products of fillet, carry out punching press, the product tear face smoother after punching press, product quality is higher, can meet the needs that following process is used.
More than show and stated basic principle of the present invention, principal character and advantage.The technical staff of the industry should understand; the present invention is not restricted to the described embodiments; that in above-described embodiment and description, describes just illustrates principle of the present invention; without departing from the spirit and scope of the present invention; the present invention also has various changes and modifications, and these changes and improvements all fall in the claimed scope of the invention.The claimed scope of the present invention is defined by appending claims and equivalent thereof.
