Abstract
The utility model relates to an inside hexagon cylindrical-head screw mould nest plate which comprises a nest plate body, wherein the outer surface of the nest plate body is a conical surface; and the nest plate body is made of high-carbon high-chromium alloy steel. The inside hexagon cylindrical-head screw mould nest plate is characterized in that an inner ring which is made of a tungsten steel material is arranged in the nest plate body; the inner hole of the inner ring is conical and the conicity of the inner hole is alpha; the conicity alpha is 12 DEG; and an air groove is arranged at the bottom of the nest plate body. According to the utility model, the nest plate body is made of common mould steel and the inner ring is made of the tungsten steel material, so that the precision and quality of outer surfaces of bolt heads are ensured and the production cost is effectively controlled; the conicity of the inner hole of the inner ring is controlled, so that the conicity of cylindrical heads of screws is ensured during preforming and then the cylindricity of the cylindrical heads after the head forming (inside hexagon stamping) is controlled; and the air groove is arranged at the bottom of the mould nest plate, so that heat in the head stamping process of moulds is effectively and timely diffused and then the product forming quality is ensured.
Description
Technical field
The utility model relates to a kind of mould, relates in particular to hexagonal socket cap screw mold nest plate in a kind of having.
Background technology
Along with the development of enterprise, building trade has also obtained fast development, and attaching parts such as screw obtain a large amount of uses, produces attaching parts such as hexagon socket head cap screw at present and mainly passes through die production.Wherein nest plate is exactly that its main preformed is in the head of screw as one of cold forging die commonly used in the screw production industry, and the control accuracy of its size will satisfy the national standard of screw product.When the preformed of hexagon socket cap head screw head; Need size Control (upward the big end is little) in the certain taper scope, otherwise when moulding socket cap head punching press inner hexagonal hole, tapering (it is big to go up handle) appears in socket cap easily with socket cap; Make it can not satisfy the national standard of screw product; Cause percent defective high, production efficiency is low, and product quality can't strict guarantee.
The utility model content
The utility model purpose be provide for the deficiency that overcomes prior art a kind of can strict control screw cylinder head preformed tapering, guarantee the interior hexagonal socket cap screw mold of the cylindricity of screw socket cap after the head moulding.
For achieving the above object; The technical scheme that the utility model adopts is: hexagonal socket cap screw mold nest plate in a kind of; Comprise the nest plate body; Said this external surface of nest plate is a taper seat, and said nest plate body adopts high carbon high chromium alloy tool steel to process, and it is characterized in that: be provided with inner ring in the said nest plate body; Said inner ring adopts the wolfram steel material to process; Said inner ring endoporus is shaped as taper shape; Said endoporus conicity is α °; Said nest plate body bottom has air drain.
Preferably, said conicity α ° is 12 °.
Preferably, said air drain has 3, circular array.
Because the utilization of technique scheme, the utility model compared with prior art has advantage:
The interior hexagonal socket cap screw mold nest plate of the utility model scheme, nest plate body adopt common mould steel to process, and its inner ring adopts the wolfram steel material to process, and has guaranteed the precision and the quality of screw head outer surface, has effectively controlled production cost; The control of the tapering of its inner ring endoporus, the tapering when having guaranteed the preformed of screw socket cap, and then (in the punching press after the hexagonal) socket cap cylindricity after having controlled the head moulding; Be provided with air drain in mould nest plate bottom, effectively and in time distributed the heat in the mould punching press head process, guarantee the formed product quality.
Description of drawings
Below in conjunction with accompanying drawing the utility model technical scheme is described further:
Accompanying drawing 1 is the Facad structure cutaway view of a kind of interior hexagonal socket cap screw mold of the utility model;
Accompanying drawing 2 is the upward view of a kind of interior hexagonal socket cap screw mold of the utility model;
Wherein: 1, nest plate body; 2, inner ring; 3, endoporus; 4, air drain; 5, taper seat.
The specific embodiment
Below in conjunction with accompanying drawing and specific embodiment the utility model is done further to specify.
Accompanying drawing 1,2 is the described a kind of interior hexagonal socket cap screw mold nest plate of the utility model; Comprise nest plate body 1; The outer surface of said nest plate body 1 is a taper seat 5, and said nest plate body 1 adopts high carbon high chromium alloy tool steel to process, and is provided with inner ring 2 in the said nest plate body 1; Said inner ring 2 adopts the wolfram steel material to process; Endoporus 3 in the said inner ring 2 be shaped as taper shape, conicity is 12 °; Have the air drain 4 of 3 circular array in nest plate body 1 bottom.
Below only be the concrete exemplary applications of the utility model, the protection domain of the utility model is not constituted any limitation.All employing equivalents or equivalence are replaced and the technical scheme of formation, all drop within the utility model rights protection scope.
