Abstract

The utility model discloses a burr-free bidirectional detachable punch, comprising a punch seat. The burr-free bidirectional detachable punch is characterized in that one opening is inwards concavely formed in each of two ends of the punch seat; one blade is arranged in each opening; screw rods penetrate through the rear ends of the corresponding blades and the punch seat part at two sides of the openings; the parts, penetrating out of the punch seat, of the screw rods are locked and fixed by nuts; an opening slot is arranged in each of two sides of each opening; convex inverted buckles are respectively arranged at two sides of the rear ends of the blades; the inverted buckles at two sides and the opening slots at the corresponding sides are matched and clamped; two sides of a machining end of each blade are set to be circular corners. The problems that the punch seat and the blade are integrally formed, a whole punch is scrapped as the blade is gradually consumed and damaged due to abrasion, the production is performed in a single surface mode as only one blade is fixed on the punch seat in common, and burrs easily occurs are solved. The utility model provides the burr-free bidirectional detachable punch with the advantages that the structure is simple, the use is convenient, the blades can be detached, and the machining quality is high.

Description

A kind of without the two-way removable drift of burr
Technical field
The utility model relates to a kind of drift, particularly relates to a kind of without the two-way removable drift of burr.
Background technology
Its punch holder of current drift and blade adopt one-body molded, after the long-time use of blade, consume gradually because of wearing and tearing, final blade can not use because damage is scrapped, because blade can not separate with punch holder, 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.Simultaneously 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 drift mostly is unidirectional drift in addition, generally only fixes a blade in punch holder, can only produce by one side, and the scope of application is little, and use cost is higher.
Utility model content
For the punch holder and the blade that solve drift in prior art adopt one-body molded, blade consumes gradually and damages because of wearing and tearing, cause whole drift also just to scrap, and generally only fix a blade in punch holder, can only produce by one side, the scope of application is little, easily occur the problem of burr, it is a kind of simple in structure, easy to use that the utility model provides, can removal of inserts, and processing quality high without the two-way removable drift of burr.
In order to address the above problem, technical solution adopted in the utility model is:
A kind of without the two-way removable drift of burr, comprise punch holder, it is characterized in that: also comprise blade, screw rod and nut, cave inward respectively and be provided with an opening at the two ends of punch holder, in each opening, be provided with a blade, described screw rod is through the rear end of corresponding blade and the punch holder part of opening both sides, and screw rod passes the part of punch holder and fixes by nut check, be respectively arranged with fluting in each opening both sides, be respectively arranged with the back-off of protrusion in blade rear end both sides, the described both sides back-off clamping that matches with the fluting of respective side, fillet is arranged in the processing end both sides of described blade.
Aforesaid one, without the two-way removable drift of burr, is characterized in that: described fluting is triangle fluting.
Aforesaid one, without the two-way removable drift of burr, is characterized in that: described back-off is triangle back-off.
Aforesaid one, without the two-way removable drift of burr, is characterized in that: two cross-notchings of described setting are between two screw rods.
The beneficial effects of the utility model are: the utility model, without the two-way removable drift of burr, is fixed two blades by a punch holder, and the scope of application is wider, provides cost savings, and has improved efficiency.Simultaneously the utility model is fixed on blade in punch holder with two kinds of removablies of fluting by screw rod and nut and back-off, has both ensured fastness and reliability that blade connects, and while the utility model can be dismantled, and is convenient for changing blade, provides cost savings.Be arranged to fillet in the processing end both sides of blade in addition, by fillet, product 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.
Brief description of the drawings
Fig. 1 is that the utility model is without the two-way removable punch structure schematic diagram of burr.
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 without the two-way removable drift of burr, comprise punch holder 1, blade 2, screw rod 6 and nut 7, cave inward respectively and be provided with an opening 3 at the two ends of punch holder 1, in each opening 3, be provided with a blade 2, described screw rod 6 is through the rear end of corresponding blade 2 and punch holder 1 part of opening 3 both sides, and the part that screw rod 6 passes punch holder 1 is locked by nut 7, be respectively arranged with fluting 4 in each opening 3 both sides, two cross-notchings 4 of described setting are between two screw rods 6.Be respectively arranged with the back-off 5 of protrusion in blade 2 both sides, rear end, described both sides back-off 5 clamping that matches with the fluting 4 of respective side, fillet 8 is arranged in the processing end both sides of described blade 2.Described fluting 4 is triangle fluting.Described back-off 5 is triangle back-off.
The utility model, without the two-way removable drift of burr, is fixed two blades 2 by a punch holder 1, and the scope of application is wider, provides cost savings, and has improved efficiency.Simultaneously the utility model is fixed on blade 2 in punch holder 1 by screw rod 6 and nut 7 and 4 two kinds of removablies of back-off 5 and fluting, both fastness and reliability that blade 2 connects had been ensured, the utility model can be dismantled simultaneously, is convenient for changing blade 2, provides cost savings.Be arranged to fillet 8 in the processing end both sides of blade 2 in addition, carry out punching press by fillet 8 products, 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 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; that in above-described embodiment and description, describes just illustrates principle of the present utility model; do not departing under the prerequisite of 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.
