The utility model discloses a kind of toughness high burr-free punch, comprise punch holder, it is characterized in that: also comprise screw, nut and blade, the side of described punch holder caves inward and is formed with a groove, a blade is provided with in groove, described screw is through the rear end of blade and the punch holder part of groove both sides, and the part that screw passes punch holder is fixed by nut check, the end of blade is provided with blade, described blade adopts the stacked compacting of some steel discs to form, and fillet is processed at the two ends of described blade.The utility model solves its punch holder of drift and blade in prior art and adopts one-body molded, and blade consumes gradually because of wearing and tearing, causes scrapping of drift, add cost, and punch product, easily on the product plane of disruption, form burr, and bulk strength is low, the problem of poor toughness, provide a kind of structure simple, intensity is high, good toughness, can quick-detachment blade, the toughness high burr-free punch that use cost is low.

Description

A kind of toughness high burr-free punch
Technical field
The utility model relates to a kind of drift, particularly relates to a kind of toughness high burr-free punch.
Background technology
Its punch holder of current drift and blade adopt one-body molded, after blade uses for a long time, consume gradually because of wearing and tearing, final blade is scrapped because damage and can not use, because blade can not be separated with punch holder, whole like this drift has also just been scrapped, and needs again to change drift, use cost improves greatly, has increased the weight of the burden of enterprise.Simultaneously because current blade is overall formation, this just causes blade bulk strength lower, poor toughness, easily ruptures in blade place, causes the damage of cutter.Punch product current in addition, easily forms burr on the product plane of disruption, reduces the quality of product, can not meet the accurately machined requirement of some products.
Utility model content
Adopt one-body molded to solve its punch holder of drift and blade in prior art, blade consumes gradually because of wearing and tearing, causes scrapping of drift, add cost, and punch product, easily on the product plane of disruption, form burr, and bulk strength is low, the problem of poor toughness, it is simple that the utility model provides a kind of structure, and intensity is high, good toughness, can quick-detachment blade, the toughness high burr-free punch that use cost is low.
In order to solve the problem, technical solution adopted in the utility model is:
A kind of toughness high burr-free punch, comprise punch holder, it is characterized in that: also comprise screw, nut and blade, the side of described punch holder caves inward and is formed with a groove, is provided with a blade in groove, and described screw is through the rear end of blade and the punch holder part of groove both sides, and the part that screw passes punch holder is fixed by nut check, the end of blade is provided with blade, and described blade adopts the stacked compacting of some steel discs to form, and fillet is processed at the two ends of described blade.
Aforesaid a kind of toughness high burr-free punch, is characterized in that: described blade is rectangular blade.
Aforesaid a kind of toughness high burr-free punch, is characterized in that: described punch holder adopts stainless steel material to make.
Aforesaid a kind of toughness high burr-free punch, is characterized in that: described blade adopts high-abrasive material to make.
Aforesaid a kind of toughness high burr-free punch, is characterized in that: described blade adopts wolfram steel material to make.
Aforesaid a kind of toughness high burr-free punch, is characterized in that: described nut adopts hex nut.
The beneficial effects of the utility model are: the utility model toughness high burr-free punch, is provided with a blade in groove, and described screw is through the rear end of blade and the punch holder part of groove both sides, and the part that screw passes punch holder is fixed by nut check.Being coordinated by screw and nut is fixed in groove by dismountable for blade, and fast easy for installation, simultaneously when breaks down, also quick release, effectively reduces cost, avoids the waste that punch holder is unnecessary.The utility model is provided with blade in the end of blade in addition, and described blade adopts the stacked compacting of some steel discs to form, and makes blade toughness greatly improve like this, and not easy fracture during use, service life is longer.Fillet is processed at the two ends of blade in addition, carries out punching press by fillet to product, the product tear face smoother after punching press, and product quality is higher, can meet the needs that following process uses.
Accompanying drawing explanation
Fig. 1 is the utility model toughness high burr-free punch structural representation.
Detailed description of the invention
Below in conjunction with accompanying drawing, the utility model will be further described.
As shown in Figure 1, a kind of toughness high burr-free punch, comprise punch holder 1, screw 4, nut 5 and blade 3, the side of described punch holder 1 caves inward and is formed with a groove 2, a blade 3 is provided with in groove 2, described screw 4 is through the rear end of blade 3 and punch holder 1 part of groove 2 both sides, and the part that screw 4 passes punch holder 1 is locked by nut 5, the end of blade 3 is provided with blade 7, described blade 7 adopts the stacked compacting of some steel discs to form, and fillet 6 is processed at the two ends of described blade 7.Described blade 3 is rectangular blade.Described punch holder 1 adopts stainless steel material to make.Described blade 7 adopts high-abrasive material to make.Described blade 3 adopts wolfram steel material to make.Described nut 5 adopts hex nut.
The utility model toughness high burr-free punch, a blade 3 is provided with in groove 2, described screw 4 is through the rear end of blade 3 and punch holder 1 part of groove 2 both sides, and the part that screw 4 passes punch holder 1 is locked by nut 5, is coordinated by screw 4 and nut 5 and be fixed in groove 2 by dismountable for blade 3, fast easy for installation, simultaneously when blade 3 damages, also quick release, effectively reduces cost, avoids the waste that punch holder 1 is unnecessary.The utility model is provided with blade 7 in the end of blade 4 in addition, and described blade 7 adopts the stacked compacting of some steel discs to form, and makes blade 7 toughness greatly improve like this, and not easy fracture during use, service life is longer.Fillet 6 is processed at the two ends of blade 7 in addition, carries out punching press by fillet 6 pairs of products, the product tear face smoother after punching press, and product quality is higher, can meet the needs that following process uses.
More than show and stated general principle of the present utility model, principal character and advantage.The technical staff of the industry should understand; the utility model is not restricted to the described embodiments; what describe in above-described embodiment and description just illustrates principle of the present utility model; under the prerequisite not departing from the utility model spirit and scope; the utility model also has various changes and modifications, and these changes and improvements all fall within the scope of claimed the utility model.The claimed scope of the utility model is defined by appending claims and equivalent thereof.
