Description
Technical field
The utility model belongs to the blanking die in stamping technology field, and in particular to a kind of tiny punch cross protection positioning
Porous mold.
Background technology
Tiny punch is commonly used in blanking die, in blanking process, when there is longitudinal direction between punch fixing plate and stripper
It when shift length generates, since tiny punch is tiny and material is hard, easily snaps off, frequently replaces punch and take time and effort, greatly
Reduce production efficiency greatly.
Utility model content
In order to solve the problems in the existing technology the utility model, provides a kind of with the tiny punching for being oriented to protection
Head cross protection positions porous mold.
In order to achieve the above purpose, the technical solution of the utility model is：A kind of tiny punch cross protection positioning is more
Punch die, including attacking head, punch holder, guide sleeve, punch body, punch fixing plate, tiny punch and stripper, wherein attacking head,
Punch holder, guide sleeve and punch body use standard universal mould structure, attacking head to be fixed by trip bolt with punch holder, punch holder
It is fixed with punch body by the hanging bolt for being arranged in axle center, punch body is solid by trip bolt and positioning pin with punch fixing plate
It is fixed, the rack positioning method of intermeshing formula is used between punch fixing plate and stripper, and fasten by positioning pin, punch is solid
Fixed board is equipped with evenly arranged raised line, and stripper is equipped with the rack of arrangement correspondings with raised line, raised line be inserted into stripper it is interior and with
Rack is intermeshed, and being centrally disposed between intermeshing raised line and rack and being fixed on punch body for tiny punch makes
It obtains tiny punch and is oriented to protection by punch fixing plate and the whole of stripper.
Preferably, the punch body be equipped with boss, with punch fixing plate using projective table type positioning, be used in combination trip bolt and
Positioning pin is fixed.
A kind of advantageous effect of tiny punch cross protection positioning porous mold provided by the utility model is：It had been punched
Cheng Zhong, when there is length travel distance to generate between punch fixing plate and stripper, due to the positioning of rack mode, what is made is tiny
Punch all in being oriented in protection, so that tiny punch is not easily broken, ensure that the working performance of tiny punch always
And service life.
Description of the drawings
Fig. 1 shows the structural schematic diagram of the utility model.
Specific implementation mode
The utility model is described in more detail with reference to the accompanying drawings and detailed description：
A kind of tiny punch cross protection positioning porous mold, including attacking head 1, punch holder 2, guide sleeve 3, punch body 4, punching
Head fixed plate 5, tiny punch 6 and stripper 7, wherein attacking head 1, punch holder 2, guide sleeve 3 and punch body 4 use standard universal mould
Lamps structure, guide sleeve 3 are arranged in the outside of punch holder 2, punch body 4 and punch fixing plate 5, and attacking head 1 passes through fastening with punch holder 2
Screw 8 is fixed, and punch holder 2 is fixed by the way that the hanging bolt 21 in axle center is arranged with punch body 4, punch body 4 be equipped with boss 41 with
Punch fixing plate 5 is positioned using projective table type, is fixed by trip bolt 8 and positioning pin 9, between punch fixing plate 5 and stripper 7
It using the rack positioning method of intermeshing formula, and is fastened by positioning pin 9, punch fixing plate 5 is equipped with evenly arranged raised line
51, stripper 7 is equipped with the rack 71 of arrangement corresponding with raised line 51, and raised line 51 is inserted into stripper 7 and is mutually nibbled with rack 71
It closes, the boss 41 for being centrally disposed between intermeshing raised line 51 and rack 71 and being fixed on punch body 4 of tiny punch 6
On so that tiny punch 6 is oriented to protection by punch fixing plate 5 and the whole of stripper 7.
In blanking process, when there is length travel distance to generate between punch fixing plate 5 and stripper 7, due to rack
The positioning of mode so that tiny punch 6 all in being oriented in protection, so that tiny punch 6 is not easily broken, ensures always
The working performance and service life of tiny punch 6.
The utility model has carried out detailed explanation by preferred embodiment.However, by studying carefully above,
Variation and increase to each embodiment are obvious for those of ordinary skill in the art.The intention of applicant
It is that all these variations and increase are all fallen in the range that the utility model claims are protected.
