Technical field
The utility model belongs to technical field of mechanical equipment, relates to a kind of wire-drawing die, especially a kind of main passive rotary cold-heading wire-drawing die of design.
Background technology
Usual wire-drawing die is all integral structure, and therefore a kind of wire-drawing die can only produce the product of single type, and production efficiency is low; Same, be integral type structure when a certain local link damages because of it, so just whole equipment must be replaced, and wire-drawing die often there will be wire drawing and to have some setbacks and product surface has the phenomenon of cut.
In order to solve prior art Problems existing, people have carried out long-term exploration, propose solution miscellaneous.Such as, Chinese patent literature discloses a kind of wire-drawing die, [application number: 201320108871.6], include die sleeve, basic unit, wire drawing hole, be followed successively by die sleeve, basic unit, wire drawing hole from outside to inside, described wire drawing hole is followed successively by inlet region, workspace, sizing area, outlet area from front to back, and the transition region in described basic unit and wire drawing hole and corresponding section, workspace are diamond coatings.
Above-mentioned scheme improves the subproblem of prior art to a certain extent, but, also at least there is following defect in the program: the waste problem that the structure that cannot solve integral type causes, and the wire drawing type of production is single, and the product surface produced still may occur cut.
Summary of the invention
The purpose of this utility model is for the problems referred to above, provides a kind of drawing process smooth and easy and the passive rotary cold-heading wire-drawing die of product surface is smooth master.
For achieving the above object, the utility model have employed following technical proposal: this master is passive, and rotary cold-heading wire-drawing die comprises mould cylinder, the forming hole that large the inner, outer end is little is provided with inside mould cylinder one end, be provided with the shaping cover being positioned at mould cylinder in forming hole the inner and go out silk braid, described shaping cover center has the sizing hole of uniform internal diameter, the described silk braid center that goes out has large wire vent hole, inner little outer end, described forming hole, sizing hole and wire vent hole are docked and forming hole successively, the center line in sizing hole and wire vent hole is located along the same line, external toothing is arranged with outside described mould cylinder, driving gear cover is engaged with in external toothing periphery, described shaping cover and go out silk braid and mould cylinder axial location circumference is rotationally connected.
In the passive rotary cold-heading wire-drawing die of above-mentioned master, between described shaping cover and mould cylinder, be provided with clutch shaft bearing; Described going out between silk braid and mould cylinder is provided with the second bearing.
In the passive rotary cold-heading wire-drawing die of above-mentioned master, one end that described mould cylinder is provided with out silk braid is provided with end cap, and the outer end of described end cap has annular retaining ring and annular retaining ring and go out between silk braid outer end to be provided with the first plane bearing.
In the passive rotary cold-heading wire-drawing die of above-mentioned master, described shaping cover and go out between silk braid to be provided with the second plane bearing.
In the passive rotary cold-heading wire-drawing die of above-mentioned master, be provided with step between described forming hole the inner and mould cylinder, between described shaping cover end and step, be provided with the 3rd plane bearing.
In the passive rotary cold-heading wire-drawing die of above-mentioned master, described forming hole and wire vent hole are arcuate socket.
Compared with prior art, the advantage of the passive rotary cold-heading wire-drawing die of this master is: 1, cost-saving, and the structure disperses of integral type is become a few part, and various piece is detachable replacement, therefore, when there is local fault, can faulty component be replaced but not replace whole equipment; 2, production diversity, replaceable shaping cover realizes the product that Unified Device produces different model; 3, wire drawing is smooth and easy, and product surface is level and smooth, at shaping cover, goes out between silk braid etc. and arranges bearing, makes it mutually rotate to reach wire drawing smooth and easy and the effect that product is level and smooth.
Accompanying drawing explanation
Fig. 1 is the structural representation that the utility model provides.
In figure, mould cylinder 1, forming hole 2, shaping cover 3, go out silk braid 4, sizing hole 5, wire vent hole 6, external toothing 7, driving gear cover 8, clutch shaft bearing 9, second bearing 10, end cap 11, annular retaining ring 12, first plane bearing 13, second plane bearing 14, step 15, the 3rd plane bearing 16.
Detailed description of the invention
Below in conjunction with the drawings and specific embodiments, the utility model is described in more detail.
As shown in Figure 1, this master is passive, and rotary cold-heading wire-drawing die comprises mould cylinder 1, the forming hole 2 that large the inner, outer end is little is provided with inside mould cylinder 1 one end, be provided with the shaping cover 3 that is positioned at mould cylinder 1 in forming hole 2 the inner and go out silk braid 4, described shaping cover 3 center has the sizing hole 5 of uniform internal diameter, described silk braid 4 center that goes out has large wire vent hole 6, inner little outer end, described forming hole 2, sizing hole 5 and wire vent hole 6 are docked and forming hole 2 successively, the center line in sizing hole 5 and wire vent hole 6 is located along the same line, traditional wire-drawing die integral structure is split and comes, each structure can be replaced separately, when a certain structure breaks down, this damaged structure can be replaced separately but not replace whole mould, provide cost savings, simultaneously, the shaping cover 3 of different model can be replaced to produce the product of different model, reach the effect of a tractor serves several purposes.
