Abstract
The utility model discloses a cutting steel wire wire-drawing die. The die comprises a die sleeve and a die core which is inlaid inside the die sleeve. A wire-drawing hole is arranged inside the die core. An inlet area, a compression area, a sizing area and an outlet area are sequentially arranged in the wire-drawing hole along an axial direction. The inner wall of the axial section of the wire-drawing hole is of a hyperbolic curve shape. An inclined angle of a die hole in the inlet area of the die core is 59-610, an inclined angle of a die hole in the compression area of the die core is 51-530, and an inclined angle of a die hole in the outlet area of the die core is 60-620. According to the cutting steel wire wire-drawing die, an inclined angle of a die hole in an inlet area of an existing wire-drawing die core is changed into 590 from the existing 300-600, and thus the formation of an integrated lubrication area between a steel wire and the die hole is facilitated, the contact surface of lubricating agents and the steel wire is enlarged, the lubrication effect of the steel wire in the compression area after the steel wire enters the die is improved, and the abrasion of the die core is reduced. Due to the fact that the angle of the die hole in the outlet area of the die core is changed from the existing 100-300 into 620, working pressure of the steel wire to the outlet area can be reduced, die core cracking of the outlet area can be prevented and the like.
Description
Technical field
The utility model relates to a kind of particular manufacturing craft, is specifically related to a kind of cutting steel wire wire-drawing die.
Background technology
The silicon chip cutting steel wire is a kind of novel cutting material that grew up in recent years, because the required precision of solar silicon wafers is very strict, so the requirement for the cutting steel wire of cutting silicon wafer is also very strict, because cutting steel wire intensity and hardness are high, and diameter is very little, and between 0.08 mm ~ 0.16 mm, the margin of tolerance of steel wire diameter is in 3 ‰, therefore, the wire-drawing die of drawing cutting steel wire also needed very high requirement.Existing cutting steel wire wire-drawing die is because the cutting steel wire time of occurrence is short, difficulty is large, it is high to require, still be at present the stage of groping, researching and developing, technical immature, the service life of wire-drawing die is short, and precision is difficult to keep, and causes simultaneously the drawing lumber recovery of cutting steel wire not high, cost increases, therefore require further improvement the production technology of wire-drawing die, increase the service life, improve the drawing quality.
The utility model content
The purpose of this utility model is to overcome the defective that exists in the prior art, and a kind of lumber recovery that improves cutting steel wire is provided, and improves the service life of wire-drawing die, satisfies the cutting steel wire wire-drawing die that the high-quality drawing of cutting steel wire requires.
For achieving the above object, the technical solution of the utility model is a kind of cutting steel wire wire-drawing die of design, it is characterized in that, described mould comprises die sleeve and is embedded in the interior core rod of die sleeve, in described film core, be provided with the wire drawing hole, described wire drawing hole is provided with inlet region, compressional zone, sizing area and outlet area vertically successively, and the inwall of described wire drawing hole axial section is the hyperbolic wire, and the angle degree of described core rod inlet region nib is 59 ~ 61
0, the angle degree of described core rod compressional zone nib is 51 ~ 53
0, the angle degree of described core rod outlet area nib is 60 ~ 62
0
Wherein preferred technical scheme is that the angle degree of described core rod inlet region nib is 59
