Wire drawing combination pressure mould
Technical field
The utility model relates to a kind of wire drawing combination pressure mould that is used on the steel bead wire production line.
Background technology
The single sintered-carbide die that generally adopts on the steel bead wire production line relatively is applicable to the production requirement of low speed drawing at present, causes a series of drawback on the production line of high speed drawing easily, therefore is not suitable for high speed drawing.
Summary of the invention
The purpose of this utility model is by experiment, invents out a cover wire drawing combination pressure mould, solves the problem that occurs in the high speed drawing process.
For reaching above purpose, in diaphragm capsule, be provided with the work mould, set up a pressure mould at an end of work mould, work mould and pressure die combination form the combination pressure mould together, and described pressure mould is a platform shape cylinder, and the middle part is provided with the wire drawing hole.
Form wire drawing combination pressure mould by above the utility model work mould and the pressure die combination of being provided with, the combination pressure mould is contained in the diaphragm capsule operates then, can improve the drawing speed of steel wire, reduce the loss of mould, and prolong die life.
Description of drawings
Now in conjunction with the accompanying drawings the utility model is further described.
Fig. 1 is a front view of the present utility model.
Among the figure 1, diaphragm capsule 2, work mould 3, pressure mould
The specific embodiment
As shown in Figure 1, the utility model is provided with work mould 2 in diaphragm capsule 1, sets up a pressure mould 3 at an end of work mould 2, and work mould 2 and pressure mould 3 are combined and formed the combination pressure mould, and described pressure mould 3 is a platform shape cylinder, and the middle part is provided with the wire drawing hole.
Operation principle: lubricant is when high-speed wire-drawing, steel wire enters the pressure mould 3 in the diaphragm capsule 1, by pressure mould 3 a large amount of lubricants of introducing, in the gap of pressure mould 3 and work mould 2, melt the high pressure that produces owing to high-speed and high-temperature, the boundary lubrication condition is transformed into hydrodynamic lubrication, thereby has improved lubricant effect, accelerated the steel wire drawing speed.
