Abstract
The utility model discloses a tool sticking preventing punching die. The punching die comprises an upper die base, a punching tool and a lower die base, wherein the punching tool is fixedly arranged on the lower surface of the upper die base; a punching slot corresponding to the punching tool is formed in the upper surface of the lower die base. The tool sticking preventing punching die comprises a base, a top base, a connecting piece and elastic pieces, wherein the top base is detachably connected on the upper surface of the base; the connecting piece is arranged between the base and the top base; the elastic pieces are arranged between the connecting piece and the top base. The tool sticking preventing punching die also comprises a material ejecting piece, wherein one end of the material ejecting piece is fixedly arranged on the connecting piece, and the other end of the material ejecting piece passes through a tool hole of the punching tool; when the elastic pieces are in a free state, the other end of the material ejecting piece exceeds the bottom end of the tool hole. The tool sticking preventing punching die has the advantages that by additionally arranging the material ejecting piece to the die, the die cutting and waste discharge processes can be smoother, thus ensuring the clean tool edge of the die, effectively improving the product quality and increasing the capacity, effectively prolonging the service life of the die and reducing the production costs of enterprises.
Description
Technical field
the utility model relates to a kind of Non-stick knife punching die.
Background technology
along with the develop rapidly of electronics industry, the cross cutting demand of various electronic materials also increases increasingly, the operation principle of general cross cutting is within the mould of sizing, by the size of exerting pressure, make the separation of products being cut, but in process, the problem of sticky cutter perplexs whole cross cutting industry always, conventionally adopting water spray or spray mould release etc. on mould to alleviate sticky cutter problem, shortcoming is water stain or mould release etc. can remain on product, affects product quality.
Utility model content
when being to provide a kind of punching, the purpose of this utility model can effectively alleviate the Non-stick knife punching die of sticky cutter problem.
for achieving the above object, the technical solution adopted in the utility model is: a kind of Non-stick knife punching die, comprise upper bolster, be fixedly arranged on the piercing knife of described upper bolster lower surface, upper surface is provided with the die shoe of the jet-bedding of corresponding described piercing knife, described Non-stick knife punching die comprises pedestal, dismountable footstock that is connected to described pedestal upper surface, be located at the connector between described pedestal and described footstock, be located at the elastic component between described connector and described footstock, described Non-stick knife punching die also comprises liftout part, one end of described liftout part is fixedly arranged on described connector, the other end of described liftout part is arranged in the tool bore of described piercing knife, described elastic component is in the time of free state, the other end of described liftout part exceeds the bottom of described tool bore.
preferably, on described connector, be installed with locating part, the corresponding through hole that allows described locating part to pass that offers on described pedestal.
preferably, the shape of described tool bore is one or more in circular, square, L shaped, abnormity.
preferably, the material of described Non-stick knife punching die is aluminium, stainless steel, high-carbon steel or the steel molecular structure one in high-quality steel closely.
due to the utilization of technique scheme, the utility model compared with prior art has following advantages: a kind of Non-stick knife punching die of the present utility model, by increase the design of liftout part on mould, can allow cross cutting and waste discharge process more unobstructed, ensure the clean of mold notch, effectively improve the quality of products and improve production capacity, effectively having extended die life, and reducing the production cost of enterprise.
Brief description of the drawings
accompanying drawing 1 is the sectional view of the utility model upper bolster.
wherein: 1, upper bolster; 2, piercing knife; 3, pedestal; 4, footstock; 5, connector; 6, elastic component; 7, liftout part; 8 locating parts.
Detailed description of the invention
below in conjunction with accompanying drawing, the technical solution of the utility model is further elaborated.
shown in Figure 1, a kind of Non-stick knife punching die, piercing knife 2, the upper surface that comprise upper bolster 1, is fixedly arranged on upper bolster 1 lower surface is provided with the die shoe of the jet-bedding of corresponding described piercing knife 2, Non-stick knife punching die comprises pedestal 3, dismountable footstock 4 that is connected to pedestal 3 upper surfaces, be located at connector 5 between pedestal 3 and footstock 4, be located at the elastic component 6 between connector 5 and footstock 4, on connector, be installed with locating part 8, the corresponding through hole that allows this locating part 8 to pass that offers on pedestal 3.Non-stick knife punching die also comprises liftout part 7, and one end of liftout part 7 is fixedly arranged on connector 6, and the other end of liftout part 7 is arranged in the tool bore of piercing knife 2, and the shape of tool bore is one or more in circular, square, L shaped, abnormity.Elastic component 6 is in the time of free state, the other end of liftout part 7 exceeds the bottom of tool bore, by this setting, in die-cut process, upper bolster 1 is close to die shoe, liftout part 7 can first touch product to be punched and then compress elastic component 6, then piercing knife 2 just can touch product to be punched and cut, after cutting completes, upper bolster 1 starts away from die shoe, because elastic component 6 is compressed, now elastic component 6 meeting bullets are stretched simultaneously liftout part 7 are ejected downwards, liftout part 7 ejects the waste material after die-cut completing by elastic force in the product from die-cut, better complete the function of waste discharge.The material of Non-stick knife punching die is aluminium, stainless steel, high-carbon steel or the steel molecular structure one in high-quality steel closely, and this Non-stick knife punching die can regulate hardness by Technology for Heating Processing according to user's request.
the concrete course of work of setting forth lower the present embodiment below: product to be punched is placed on die shoe, upper bolster 1 moves downward near die shoe, first liftout part 7 touches product to be punched, upper bolster 1 continues downwards, liftout part 7 is compressed to be taken in tool bore, elastic component 6 is compressed, now tool bore contact die-cut product to be cut, in the time of die-cut completing, upper bolster 1 moves upward, now the downward bullet of compressed elastic component 6 is stretched and by connector 6, liftout part 7 is ejected downwards, liftout part 7 ejects the waste material under punched after stretching out tool bore from product, complete one-step punching process.
above-described embodiment is only explanation technical conceive of the present utility model and feature; its object is to allow person skilled in the art can understand content of the present utility model and be implemented; can not limit protection domain of the present utility model with this; all equivalences of doing according to the utility model Spirit Essence change or modify, and all should be encompassed in protection domain of the present utility model.
