Abstract
The invention discloses an easy-to-disassemble piercing punch and a pulling device. The piercing punch comprises a punching end and a fixed end fixed with a punch retainer; an anti-rotation limited block is arranged at the tail end of the fixed end; the section of the anti-rotation limited block is hexagonal; the minimum diameter of the anti-rotation limited block is larger than the diameter of the fixed end; a straight slot is formed in the upper end part of the anti-rotation limited block; the cross section of the straight slot is inverted T-shaped ; the pulling device comprises a handle, a pulling rod and a pulling piece; the handle is connected onto the upper end of the pulling rod; the pulling piece is linear; and the two ends of the pulling piece are semi-circular. The piercing punch and the pulling device have the advantages that the structure is simple; the design is reasonable; all that is needed is to clamp the pulling piece of the pulling device in a groove in the upper end of the piercing punch, then rotate by 90 degrees, clamp the pulling piece on the inner wall of the groove, and apply a force upwards vertically, the piercing punch can be pulled out from a punch fixed seat simply and conveniently, and is not be damaged; the disassembly is convenient; the working efficiency is improved greatly; and the piercing punch and the pulling device can be popularized on a large scale.
Description
Technical field
The invention belongs to Stamping Die Technology field, especially relate to a kind of easily detachable piercing punch and driver-extractor.
Background technology
Diel mainly comprises the piercing punch and punching concave die that cooperatively interact, and piercing punch is assemblied in punch retainer, and punching concave die is assemblied in die block.Piercing punch and punching concave die are consumable accessorys, need repair a die cutting edge and change spare part after mould uses a period of time, but at present conventional diel is when disassembling, need with instrument, piercing punch to be pounded out from the reverse side of punch retainer, relatively lose time, and this method can damage punch cutting edge, have a strong impact on daily efficiency, be therefore necessary a kind of easily detachable piercing punch of design and corresponding driver-extractor.
Summary of the invention
For the technical problem of above-mentioned existence, the object of the invention is: propose a kind of easily detachable piercing punch and driver-extractor.
Technical solution of the present invention is achieved in that a kind of easily detachable piercing punch and driver-extractor, the stiff end that described piercing punch comprises punching press end and fixes with punch retainer; The edge, bottom of described punching press end has blade; The tail end of described stiff end is provided with an anti-rotation limited block; Described anti-rotation limited block cross section is hexagon; The minimum diameter of described anti-rotation limited block is greater than the diameter of stiff end; Described anti-rotation limited block upper end offers a flat recess; The cross section of described flat recess becomes inverted T shape; Described driver-extractor comprises handle, plays dead man and play paddle; Described dead man is cylindric; Described handle has been connected to the upper end of dead man; Described paddle is yi word pattern, and two ends are semicircle shape; The width of described paddle equals the width of flat recess upper end.
Preferably, arc draw ring is provided with above described handle.
Preferably, the length of described paddle equals the width of a word groove the widest part.
Due to the utilization of technique scheme, the present invention compared with prior art has following advantages:
Piercing punch of the present invention and corresponding driver-extractor, structure is simple, reasonable in design, as long as driver-extractor to be played in groove that paddle is stuck in piercing punch upper end then 90-degree rotation, paddle will be played and be stuck on groove inner wall, firmly just can simply and easily piercing punch be extracted from punch holder vertically upward, do not damage punch again, convenient disassembly, substantially increases operating efficiency, can promote on a large scale.
Accompanying drawing explanation
Below in conjunction with accompanying drawing, technical solution of the present invention is described further:
Accompanying drawing 1 is the structural representation of piercing punch of the present invention;

Wherein: 1, punching press end; 2, stiff end; 3, anti-rotation limited block; 4, flat recess; 5, handle; 6, dead man is played; 7, paddle is played; 8, draw ring.
Detailed description of the invention
Below in conjunction with accompanying drawing, the present invention is described.
Easily detachable piercing punch of the present invention and driver-extractor, the stiff end 2 that described piercing punch comprises punching press end 1 and fixes with punch retainer; The edge, bottom of described punching press end 1 has blade; The tail end of described stiff end 2 is provided with an anti-rotation limited block 3; Described anti-rotation limited block 3 cross section is hexagon; The minimum diameter of described anti-rotation limited block 3 is greater than the diameter of stiff end 2; Described anti-rotation limited block 3 upper end offers a flat recess 4; The cross section of described flat recess 4 becomes inverted T shape; Described driver-extractor comprises handle 5, plays dead man 6 and play paddle 7; Described dead man 6 is in cylindric; Described handle 5 has been connected to the upper end of dead man 6; Described paddle 7 is in yi word pattern, and two ends are semicircle shape; The width of described paddle 7 equals the width of flat recess 4 upper end; The length of described paddle 7 equals the width of word groove 4 bottom.When driver-extractor of the present invention uses, as long as will paddle card 7 then 90-degree rotation in the groove of piercing punch upper end be played, the two ends semicircle shape design playing paddle 7 ensure that the lifting surface area that paddle is vertically stuck on a word groove inner wall maximizes, and then firmly just can be extracted from punch holder by piercing punch simply and easily vertically upward.
Further instruction, is provided with draw ring 8 above described handle 5, and one facilitates manual effort to pull up, and two also facilitate connecting power device, utilizes power set to be extracted by piercing punch.
Piercing punch of the present invention and corresponding driver-extractor, structure is simple, and reasonable in design, convenient disassembly, does not damage punch again, substantially increases operating efficiency, can promote on a large scale.
Above-described embodiment is only for illustrating technical conceive of the present invention and feature; its object is to person skilled in the art can be understood content of the present invention and be implemented; can not limit the scope of the invention with this; all equivalences done according to Spirit Essence of the present invention change or modify, and all should be encompassed in protection scope of the present invention.
