Description
Technical field
The utility model relates to a kind of drift, particularly relates to a kind of high-strength light 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.The simultaneously current whole quality of blade is comparatively large, affects the use of drift, and adopts stainless steel material to make, and cost is also higher.The bond strength of blade and punch holder is inadequate in addition, often easily causes the damage of blade, brings greater loss to enterprise.
Utility model content
In order to solve the problems of the prior art, it is simple that the utility model provides a kind of structure, and quality is light, and reduce costs, bond strength is high, good toughness, can quick-detachment blade, the high-strength light 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 high-strength light 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, fillet is processed at the two ends of described blade, punch holder is welded with two butt strips, the free end of butt strip is provided with hook, two flutings are provided with in the rear end of blade, the hook of described butt strip can stretch in blade correspondence fluting and be connected, the middle part of blade is provided with multiple lightening grooves.
Aforesaid a kind of high-strength light toughness high burr-free punch, is characterized in that: described two butt strips are parallel to each other.
Aforesaid a kind of high-strength light toughness high burr-free punch, is characterized in that: described punch holder adopts stainless steel material to make.
Aforesaid a kind of high-strength light toughness high burr-free punch, is characterized in that: described lightening grooves setting direction is mutually vertical with knife-blade direction.
Aforesaid a kind of high-strength light toughness high burr-free punch, is characterized in that: described blade adopts wolfram steel material to make.
Aforesaid a kind of high-strength light 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 high-strength light toughness high burr-free punch, 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.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.
The utility model drift is provided with multiple lightening grooves at the middle part of blade, and lightening grooves setting direction is mutually vertical with knife-blade direction, significantly reduces the quality of blade like this, provides cost savings, and uses more flexible.In punch holder, be welded with two butt strips simultaneously, the free end of butt strip be provided with hook, be provided with two flutings in the rear end of blade, by hook and blade slotted engagement, add the bonding strength of punch holder and blade, use more safe and reliable.
