Description

A kind of multistation cold extrusion forming method of sleeve
Technical field
The present invention relates to the manufacturing technology field of extruded sleeve.
Background technology
Sleeve is a kind of instrument commonly used, and its profile is a cylinder, and sleeve has central through hole, and central through hole comprises the hexagonal hole section that is in a side and the cubic hole section of opposite side, between cubic hole section and the hexagonal hole section middle circular hole portion is arranged, and horizontal septal fossula is arranged in the hexagonal hole.At present, make sleeve and generally adopt turning, operation is various, and especially the difficulty of processing in horizontal septal fossula in the hexagonal hole and cubic hole is big, efficient is low, and hole wall is more crude, and product quality can't guarantee.And sleeve has the bigger characteristics of central through hole, therefore, with traditional manufacturing process can cause cut the material weight greater than moulding after product weight, waste of raw materials is very big, cost is higher.
Summary of the invention
Technical problem to be solved by this invention provides a kind of multistation cold extrusion forming method of sleeve, can save raw material, reduces production costs, and improves the quality of products.For this reason, the present invention is by the following technical solutions: it comprises that fracture forms the step of cold extrusion materials and parts, behind fracture, is provided with following cold extrusion and handles:
A. to the shaping bundle limit, two ends of materials and parts,
B. pilot hole is dug at the two ends of materials and parts, wherein, the aperture that need are dug the pilot hole that the end in hole, sleeve four directions dug is the spigot surface shape and greater than the aperture in hole, sleeve four directions,
The end face that C. materials and parts need be dug hexagonal hole faces the place ahead, on the basis of pilot hole, and the length of digging the hexagonal hole of sleeve and prolonging materials and parts,
The end face that D. materials and parts need be dug cubic hole faces the place ahead, digs the cubic hole of sleeve on the basis of pilot hole, forms the pilot hole section at the bottom of the hole, and prolongs materials and parts,
E. the hole wall of described hexagonal hole is dug sleeve and is in horizontal septal fossula in the hexagonal hole,
F. at the bottom of the hole of hexagonal hole, dig Zhong Yuan hole and pilot hole,
G. dash the materials and parts between logical cubic hole and the Zhong Yuan hole, form the small sircle hole of sleeve;
A is handled in described cold extrusion and the cold extrusion treatments B is combined as 1 cold extrusion station or is no more than 4 cold extrusion stations;
Described cold extrusion is handled C and is carried out after the cold extrusion treatments B, or, when the cold extrusion treatments B is divided into a plurality of station, can be in last station of cold extrusion treatments B and carries out;
Cold extrusion processing F and cold extrusion processing E, cold extrusion processing C or cold extrusion processing D are in same station or carry out in a station separately;
E is handled in cold extrusion and cold extrusion processing D carries out with station or be in after the cold extrusion processing D and before the cold extrusion processing G carrying out.
A is handled in cold extrusion can be divided into 1 road or 2 roads, promptly finishes the task that A is handled in cold extrusion by the cold extrusion of one and 2 station, for example, and the 1st first end face of station shaping, second end face of the 2nd station shaping; The cold extrusion treatments B also can be divided into 1 road or 2 roads, promptly finishes the task of cold extrusion treatments B by the cold extrusion of one and 2 station, and for example, the 1st station digs pilot hole to first end face, and the 2nd station digs pilot hole to second end face; The combination that A and cold extrusion treatments B are handled in cold extrusion can be a design station number of handling A and cold extrusion treatments B itself according to cold extrusion, carry out permutation and combination and the processing of the cold extrusion of 4 stations more than being formed up to, such as, after the combination, the 1st first end face of station shaping, the 2nd station digs locating hole to last end face, and to back one end face shaping, the 3rd station digs locating hole to back one end face, in this case, cold extrusion is handled C and be may be incorporated in the 3rd station, and this is that very reasonably station can be realized the progressively cold-extrusion shaping to materials and parts in proper order, improve the cold extrusion quality, different cold extrusions are handled can be combined in on the station, too much to avoid station, influence cost.
Certainly, cold extrusion is handled A and the also available station of cold extrusion treatments B or two stations and is finished, and carries out on the station of cold extrusion processing C after them.
Cold extrusion is handled E and is preferably carried out at same station with cold extrusion processing D, and its purpose also is to make them can organic assembling, thereby neither influences the cold extrusion quality, can reduce cold extrusion station number as far as possible again.
Cold extrusion is a kind of plastic working technique, and it makes metal volume make plastic transfer under the prerequisite of not destroying metalline, reaches few cutting, does not have cutting and make metal forming.Form a large amount of metal debris when so just having avoided machining, save iron and steel and various metal material in a large number.
The design and the procedure arrangement that carry out station at target product are one of cold-stamped emphasis, the present invention is by rationally delineating the station operation, make sleeve can adopt the manufacturing of cold-stamped method, speed is fast, the precision height, the production efficiency height, can not adopt or adopt turning boring seldom, cut material weight product weight after the moulding no better than, less waste material even do not have waste material, save material greatly, reduce production costs.And cold extrusion makes metal material produce plastic deformation, and the metal inside tissue is changed, and the pulling force aspect more is added with raising, has improved mechanical performance of products, has guaranteed product quality, makes product have more advantage on function of use.
