Abstract
The invention discloses a machining method for a Z-shaped steel wire drawing die. The machining method comprises the steps of designing and machining a die blank, designing dimensions of a working tape, a sizing band and an outlet tape of the Z-shaped die and programming a machining procedure, performing rough machining on the Z-shaped drawing die, machining all the parts by an electric spark linear cutting machine, and grinding and inspecting Z-shaped steel wires. The Z-shaped steel wire drawing die produced by the technical flow can meet a design requirement; the wire drawing die is long in service life, and the produced Z-shaped steel wire is high in geometric size precision and consistent in thickness, has a smooth surface and meets the design requirement; the quality of a sealing steel wire rope is improved, and the service life is long.
Description
Technical field
The present invention relates to a kind of processing method of Z-shaped steel wire drawing die, belong to metallic article process unit technical field.
Background technology
The machining accuracy of the service life of locked coil wire rope and Z bar silk has very large relation, and in order to reach good fit between steel wire and steel wire, Z bar silk must have good geometric accuracy, realizes the close tolerance that steel wire is high and coordinates.The form accuracy missionary society of Z bar silk causes the extruding between steel wire, and interlayer is built on stilts, supports inefficacy etc., causes the very fast fracture of wire of steel wire rope and jumps silk, and steel wire rope is scrapped.And the mode of production of Z bar silk has directly determined the geometric accuracy of Z bar silk, the physical dimension complexity of Z bar silk, steel wire in drawing process, correct mould tapering, lubricant and cooling be ensure steel wire after draw completes, reach exactly desired diameter and tensile strength.If technological parameter is undesirable, the tensile strength of wire of likely producing differs greatly from requiring, and even also likely causes tiny pulling and miniature crackle in Steel Wire Surface, and this can bring and have a strong impact on to the life-span of steel wire rope.
Summary of the invention
The object of the invention is, in order to overcome the deficiencies in the prior art, provides a kind of processing method of Z-shaped steel wire drawing die, improves Mould Machining quality.
The present invention is according to the principle of steel wire plastic deformation, design a kind of special Z bar silk core rod, then calculate with computer the relative dimensions of designing Z-shaped drawing die tapering, be compiled into WEDM program, complete blank processing by WEDM, carry out again the grinding to the each position of Z-shaped die core of wire-drawing die, finally wire-drawing die is tested.
Z-shaped steel wire drawing die processing method of the present invention, by following implementation step:
1, the design of mould base and processing: the size of various Z bar silks differs, so the size design of core rod pass is inconsistent, the matching requirements of core rod and die sleeve closely cooperate.
2, design Z-shaped mold work cone, calibrating strap, the size that goes out the each position of prostomum and machining programming.
3, the roughing of Z-shaped wire-drawing die, processes each position with WEDM.
4, the grinding of Z bar silk: (1) carries out fillet processing with special tool(s) to Drawing cone; (2) with special polishing card grinding to Drawing cone, calibrating strap, go out prostomum and carry out respectively milled processed.
5, inspection: ground and checked the roughness at each position whether to reach requirement with magnifying glass afterwards, then with projecting apparatus, the size of calibrating strap has been tested.
Reach designing requirement with the Z-shaped wire-drawing die that above work flow is produced, wire-drawing die long service life, the Z bar silk geometric accuracy of producing is high, poker is consistent, and smooth surface reaches designing requirement, thereby make the structural behaviour of the locked coil wire rope of producing approach Theoretical Design, with the Z bar silk comparison that other modes are produced, surface quality increases substantially, and greatly improve the service life of steel wire rope.
Detailed description of the invention
Below in conjunction with embodiment, the present invention is described in further detail:
The work method that Z-shaped steel wire drawing die of the present invention adds, by following implementation step:
1, the design of mould base and processing: the size of various Z bar silks differs, so the size design of core rod pass is inconsistent, the matching requirements of core rod and die sleeve closely cooperate.
2, design Z-shaped mold work cone, calibrating strap, the size that goes out the each position of prostomum and machining programming.
3, the roughing of Z-shaped wire-drawing die, processes each position with WEDM.
4, the grinding of Z bar silk: first with special tool(s), Drawing cone is carried out to fillet processing; Then with special polishing card grinding to Drawing cone, calibrating strap, go out prostomum and carry out respectively milled processed.
5, inspection: ground the rear roughness with the each position of lens examination and whether reached requirement, then with projecting apparatus, the size of calibrating strap has been tested, can check and accept after qualified.
Reach designing requirement with the Z-shaped wire-drawing die that above work flow is produced, wire-drawing die long service life, the Z bar silk geometric accuracy of producing is high, poker is consistent, and smooth surface reaches designing requirement, thereby use the structural behaviour of the locked coil wire rope of producing to approach Theoretical Design, with the Z bar silk comparison that other modes are produced, surface quality increases substantially, and greatly improve the service life of steel wire rope.
