Abstract
The utility model provides a mold punch, comprising a solid punch body, wherein the bottom of the punch body is a punching surface, and the middle part of the punching surface is in a sunken structure. According to the mold punch, through changing the punching surface, the punching effect of the punch is greatly improved, and punched holes have no edge wrapping phenomenon and have relatively thin edges, so that the internal space of a to-be-punched object is enlarged, and in addition, the mold punch is easy for demolding, and the demolding process which is originally finished by three persons can be independently finished by only one person.
Description
Technical field
The utility model relates to a kind of die member, especially a kind of mold and punching head.
Background technology
Mould be on industrial production in order to injection moulding, blowing, extrude, various moulds and instrument that the method such as die casting or forging forming, smelting, punching press, stretching obtains required product.In brief, mould is the instrument of formed article, and this instrument consists of various parts, and different moulds consists of different parts, and it mainly realizes the processing of article profile by the change of institute's moulding material physical state.
Mould makes the product that blank becomes given shape and size under external force, can be widely used in stamping-out, shaping and punching, die forging, cold-heading, extruding, metallic sintered products compacting, compression casting, and during the shaping of the compression moulding of the goods such as engineering plastics, rubber, pottery or injection moulding processes.Mould has specific profile or cavity shape, and the contour shape that application has cutting edge can make blank separate (stamping-out) by the outline line shape; The application cavity shape can make blank obtain corresponding three-dimensional shape.Mould generally comprises dynamic model and cover half (or punch and die) two parts, both partables.Pack in the time of separately blank or take out product, make product separate with blank or be shaped while closing up.Mould is precision instrument, and is complex-shaped, bears the expansive force of blank, and structural strength, rigidity, case hardness, surface roughness and machining accuracy are all had higher requirements, and the development level of mould production is one of important symbol of machine-building level
Drift is mounted in the metal parts in diel, is applied to contact with the direct of material, makes material generation deformation, cuts material, is the die member that forms the casting die end surface shape.Drift also is punch, patrix, formpiston, red needle etc., and drift is divided into A type drift, T-shaped drift, special-shaped plunger chip.Drift is to coordinate plunger rod, drift nut, the female use together of punching.The general steel tower factory punching purposes that is used for.
When existing drift carries out punching in the handle portion to baton, because the drift bottom surface is oval in plan, make the handle place easily produce and wrap up in limit, and handle punching place periphery is thicker, also affect attractive in appearance when moving back the mould difficulty, along with to the small and exquisite further needs of easily holding of baton, the handle of baton is also more and more meticulousr, requirement to its internal circuit also requires more closely meticulous, and the handle after original drift punching, due to the existence of wrapping up in limit, greatly affected the space availability ratio of handle inside, the technological transformation of baton has been caused obstruction.
The utility model content
Technical problem to be solved in the utility model is to provide a kind of mold and punching head, can effectively solve the blocked up technical barrier in punching edge.
For solving the problems of the technologies described above, the technical solution of the utility model is:
A kind of mold and punching head, comprise solid drift body, and the bottom of described drift body is impulse face, and the middle part of described impulse face is sunk structure.
Preferably, above-mentioned mold and punching head, vertical tangent plane of described drift body is the type of falling M.
Preferably, above-mentioned mold and punching head, vertical tangent plane of described drift body is ellipse.
Preferably, above-mentioned mold and punching head, the material of described drift body is high-speed steel or wolfram steel.
Preferably, above-mentioned mold and punching head, the material of described drift body is wolfram steel.
The utility model structure has following beneficial effect:
Above-mentioned mold and punching head; by the change to impulse face; promoted greatly the punching effect of drift; make punching after punching press without wrapping up in the limit phenomenon, and edge is thinner, has increased the inner space of thing to be punched; and it is easy that described mold and punching head moves back mould; originally need the die process that moves back that 3 talents can complete, and only needed 1 people get final product complete independently, be fit to the needs that large-scale industrial is produced.
Description of drawings
Fig. 1 is the structural representation of mold and punching head described in the utility model.
Fig. 2 is the side view of mold and punching head described in the utility model.
Fig. 3 is the upward view of mold and punching head described in the utility model.
In figure: 1-drift body 2-impulse face
The specific embodiment
, for further illustrating the utility model, now coordinate accompanying drawing to be described in detail:
As shown in Figure 1-Figure 3, described mold and punching head, comprise solid drift body 1, the material of described drift body 1 is wolfram steel, the bottom of described drift body 1 is impulse face 2, the middle part of described impulse face 2 is sunk structure, and vertical tangent plane of described drift body 1 is the type of falling M, and vertical tangent plane of described drift body 1 is ellipse.Horizontal plane design at an angle due to impulse face 2, make in punching course, and stress point concentrates on impulse face 2 both sides than the center projections place, thereby overcome after punching in the past the technical barrier that limit occurs wrapping up in, move back simultaneously mould and be more prone to, only need 1 people to operate, saved the labour.
The above is only preferred embodiment of the present utility model; should be pointed out that for those skilled in the art, under the prerequisite that does not break away from the utility model principle; can also make some improvements and modifications, these improvements and modifications also should be considered as protection domain of the present utility model.
