Abstract

The utility model discloses a multistage nested cold drawing mould, which relates to the technical field of cold drawing steel tube moulds. The multistage nested cold drawing mould comprises more than two nested loops and a mould core, which are separated from each other. The cross sections of the nested loops and the mould core are respectively in an annular structure, and the inner wall of each nested loop and the outer wall of the mould core are in cone matching. The multistage nested cold drawing mould has the advantages of simple structure and convenience in assembly, disassembly and use, has time saving and labor saving effects, and can reduce the labor intensity of workers, save cost, and increase the production efficiency.

Description

A kind of multistage nested cold drawing die
Technical field
The utility model relates to mould for cold drawing of steel pipes technical field.
Background technology
Along with developing rapidly of China's science and technology, requirement to machining manufacturing is more and more higher, and the performance such as cold drawing steel tube is high with its dimensional accuracy, surface smoothness good, surface quality good, machining man-hour is few, stock utilization is high and being widely used on the big-and-middle-sized precision equipments such as machinery or hydraulic pressure.Cold-drawn is a kind of processing technology of material, corresponding metal material, cold-drawn refers in order to reach certain shape and certain mechanical property, and at material, under the condition in normal temperature, carry out drawing, the cold drawing die that existing Tube Drawing technique is used is to adopt die sleeve and core rod, in cold-drawing technology, for the steel pipe of producing different size, need to make the cold drawing die of all size, change the cold drawing die of different size, could meet the requirement that production technology is used, carry out repeatedly cold-drawn, cause operation various, cold-drawn cost is high, production efficiency is low, seriously restricted the development that enterprise produces, and the development of large hydraulic cold-draw equipment is now very ripe, the wide range of a producible steel pipe specification of cold-draw equipment, from tens to hundreds of millimeter not etc., and the mould locating hole of existing drawbench can only be processed according to maximum specification.Existing drawbench only has die sleeve and the such one-level nested rings of core rod between cold-drawn mould and locating hole, for less cold-drawn mould, what nested rings was just done is very thick very heavy, during replacing, requires great effort very much, and the mould being more or less the same for specification, also must do two cover nested rings, cause the waste of fund, the prolongation of process time, during die change, more require great effort, operating personnel's labour intensity is large, inefficiency, and material is serious waste also.
Utility model content
Technical problem to be solved in the utility model is to provide a kind of multistage nested cold drawing die, simple in structure, install and remove easy to use, time saving and energy savingly, can reduce operating personnel's labour intensity, cost-saving, enhances productivity.
For solving the problems of the technologies described above, technical solution adopted in the utility model is: a kind of multistage nested cold drawing die, comprise nested rings and core rod that split arranges, described nested rings is more than two, the cross section of described nested rings and core rod is circulus, between the inwall of described nested rings and the outer wall of core rod, is cone match.
Preferably, the outer wall of described nested rings and the outer wall of core rod are the conical surface, all have identical tapering with the conical surface of the die holder inwall matching.
Preferably, on annulus corresponding to the outer face boundary of described nested rings and core rod, adjacent nested rings, be equipped with location-plate, on the end face of the same side of annulus corresponding to each boundary, be equipped with the screwed hole identical with annulus radial distance, described location-plate is fixed together nested rings and core rod, adjacent nested rings by screwed hole and by means of bolt.
Preferably, on the annulus that described each boundary is corresponding, be evenly equipped with plural location-plate.
The beneficial effect that adopts technique scheme to produce is: the utility model adopts plural nested rings, the inwall of described nested rings and the outer wall of core rod, the outer wall of nested rings and the outer wall of core rod are the conical surface, and all there is identical tapering with the conical surface of the die holder inwall matching, the outer wall of each nested rings all can be used in conjunction with die holder, the needs that can adapt to present cold-draw equipment automation size, in use according to the suitable nested rings of the concrete selection of different die holders, when changing, can only remove or increase the nested rings that split arranges, alleviated the weight of mould, saved material, the mating surface of nested rings and core rod is the conical surface, and core rod is not only played to guide-localization and fixing, and core rod outer wall has identical tapering with serial die holder endoporus, die holder that can corresponding different size, nested rings and core rod outer face arrange location-plate, prevent the slip between nested rings and core rod, guarantee accurate positioning, nested rings and core rod can be independent use, become a kind of cold drawing die, adapt to the needs of different die holders series and different train, improved the utilization rate of mould, reduced cost, the utility model mounting or dismounting are easy to use, time saving and energy saving, can effectively enhance productivity, and save material, reduce labour intensity.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model;
Fig. 2 is the cutaway view of Fig. 1;
Mark in figure: 1-nested rings; 2-core rod; 3-location-plate.
The specific embodiment
Below in conjunction with the drawings and specific embodiments, the utility model is described in further detail.
From Fig. 1 to Fig. 2, the utility model comprises nested rings 1 and the core rod 2 that split arranges, described nested rings 1 is more than two, and the cross section of described nested rings 1 and core rod 2 is circulus, between the inwall of described nested rings 1 and the outer wall of core rod 2, is cone match; The outer wall of the outer wall of described nested rings 1 and core rod 2 is the conical surface, all has identical tapering with the conical surface of the die holder inwall matching; On annulus corresponding to the outer face boundary of described nested rings 1 and core rod 2, adjacent nested rings 1, be equipped with location-plate 3, on the end face of the same side of annulus corresponding to each boundary, be equipped with the screwed hole identical with annulus radial distance, described location-plate 3 is fixed together nested rings 1 and core rod 2, adjacent nested rings 1 by screwed hole and by means of bolt; On annulus corresponding to described each boundary, be evenly equipped with plural location-plate 3.
It between the outer wall of the inwall of nested rings 1 described in the utility model and core rod 2, is cone match; The outer wall of the outer wall of described nested rings 1 and core rod 2 is the conical surface, all has identical tapering with the conical surface of the die holder inwall matching, and adopts identical taper fit, interchangeability and versatility are good, can be used in combination easily, form the mould of different series and specification, and can guarantee accurate positioning; On annulus corresponding to the outer face boundary of described nested rings 1 and core rod 2, adjacent core rod 2, be equipped with location-plate 3, guarantee accurate positioning.
