Abstract
The invention discloses a high-stability wire-drawing mold. The high-stability wire-drawing mold comprises a wire-drawing mold sleeve (1) and a wire-drawing mold core (2), wherein bosses (3), capable of preventing the wire-drawing mold core from moving, extend from two ends of the bottom of the wire-drawing mold sleeve to the center of the wire-drawing mold sleeve. The high-stability wire-drawing mold has the beneficial effects that by arranging the bosses, capable of preventing the wire-drawing mold core from moving, at the bottom of the wire-drawing mold sleeve, the wire-drawing mold cannot shake in a drawing process; by virtue of the trapezoidal cross section of the wire-drawing mold core, the contact area between the wire-drawing mold core and the wire-drawing mold sleeve is increased, and the bonding force of the wire-drawing mold core and the wire-drawing mold sleeve is improved.
Description
Technical field
The present invention relates to wire-drawing die, relate in particular to the high stability wire-drawing die.
Background technology
In stress metal processing. make under external force metal pass through by force mould, metal cross section is long-pending compressed, and the instrument that obtains desired cross-sectional area shape and size is called wire drawing die, wire-drawing die is that wire passes through a kind of mould, make it from coarse to fine, progressively reach the needed size of people, this certain moduli tool is exactly wire drawing die, the core rod of wire drawing die generally is to use rough diamond, (rhinestone has GE to rhinestone, PCD, synthesis material etc.), wire drawing die is of many uses, such as electronic device, radar, TV, the high accuracy silk material that instrument and space flight etc. are used and tungsten filament commonly used, molybdenum filament, stainless steel wire, electric wire silk and various B alloy wire all draw out with dimaond die, dimaond die is owing to adopt natural diamond to make raw material, thereby has extremely strong wearability, and service life is high.The production technology of wire drawing die edge cover comprises several processing steps such as pressing mold, withdrawing pattern, turning.The core rod of traditional wire drawing die is cylindrical, the internal diameter of wire drawing die cover is suitable with it also to be columniform through hole, adopt interference fit that both are combined, if the strength of drawing is crossed conference wire-drawing mold core is rocked with respect to wire drawing die cover, affect the drawing quality.
Summary of the invention
The technical problem to be solved in the present invention is that wire drawing die cover and wire-drawing mold core bond strength are inadequate in the existing wire-drawing die, and in use wire-drawing mold core has wild effect, on the impact of drawing mass formation, provides a kind of high stability wire-drawing die for this reason.
Technical scheme of the present invention is: the high stability wire-drawing die, and it comprises wire drawing die cover and wire-drawing mold core, two ends, described wire drawing die cover bottom are extended with the boss that can stop described wire-drawing mold core to move to the wire drawing die cover center.
The longitudinal section of wire-drawing mold core described in the such scheme is trapezoidal.
The invention has the beneficial effects as follows by being provided with the boss that stops wire-drawing mold core to move in the wire drawing die cover bottom and limit wire-drawing mold core, guarantee that wire-drawing die is without rocking in the drawing process, the trapezoid cross section of wire-drawing mold core has strengthened both adhesions so that wire-drawing mold core and wire drawing die cover contact area increase.
Description of drawings
Fig. 1 is schematic diagram of the present invention;
Among the figure, 1, wire drawing die cover, 2, wire-drawing mold core, 3, boss.
The specific embodiment
The present invention will be further described below in conjunction with accompanying drawing.
As shown in Figure 1, the present invention includes wire drawing die cover 1 and wire-drawing mold core 2, it is up-narrow and down-wide trapezoidal that the longitudinal section of wire-drawing mold core is, there is the spatial accommodation suitable with its shape wire drawing die cover inside, wire drawing die cover bottom is provided with the boss 3 that extends to the wire drawing die cover center, and boss contacts bottom wire-drawing mold core and can limit wire-drawing mold core and pull out from the bottom of wire drawing die cover.
It is wide at the top and narrow at the bottom trapezoidal that preference of the present invention is that the longitudinal section of wire-drawing mold core is, there is the spatial accommodation suitable with its shape wire drawing die cover inside, wire-drawing mold core can more draw be combined with wire drawing die cover tighter in the process of drawing like this, and the wire drawing die cover bottom is provided with the boss that extends to the wire drawing die cover center.
The shape of boss does not limit, and can be that cross section is rectangular, circular, the structure of triangle etc., as long as can stop wire-drawing mold core to move down.
The importer who refers to wire-drawing die on described in the present invention is to, the lower Way out that refers to wire-drawing die.
The above has carried out exemplary description to the present invention by reference to the accompanying drawings; obviously specific implementation of the present invention is not subjected to the restriction of aforesaid way; as long as adopted the improvement of the various unsubstantialities that method of the present invention design and technical scheme carry out; or without improving design of the present invention and technical scheme are directly applied to other occasion, all within protection scope of the present invention.
Claims (2)
1. high stability wire-drawing die, it comprises wire drawing die cover (1) and wire-drawing mold core (2), it is characterized in that two ends, described wire drawing die cover bottom are extended with the boss (3) that can stop described wire-drawing mold core to move to the wire drawing die cover center.
2. high stability wire-drawing die as claimed in claim 1 is characterized in that described wire-drawing mold core longitudinal section is trapezoidal.
