ている。(Prior art) A continuous drawing machine is generally called a combined machine, and for example, as shown in FIG.
This is a set of mechanical equipment having a pre-straightening roll part 2, a drawing part 3 (having a drawing jaw part which is a wire transport chuck inside), a straightening part 4, a cutting part 5, and a polishing part 6 in series. Inside the drawing section 3, there is a pair of carriages 8, 8' behind the drawing die 7 (on the right side of the figure), and a pair of left and right drawing jaws (described later) are incorporated in each carriage 8, 8'. When the drawing jaws in the carriage 8 move forward toward the front process side (left side in Fig. 7) with the wire rod 1 opened left and right, the drawing jaws in the carriage 8' grip the wire rod 1 and move it to the rear process side. The wire rod 1 is conveyed to the side (right side in the figure), and then the drawing jaw in the carrier 8 transports the wire rod 1
When the wire 1 is grabbed and pulled to the right, the carriage 8' releases the wire 1 and moves to the left, performing the square motion shown. That is, the wire rod 1 can be continuously pulled out from the die 7 by the front and rear carriages 8, 8'.

ないのは、前述の事情によるものである。 FIGS. 8 and 9 show a conventional drawing jaw 10, where 11 is a base material and 12 is a cemented carbide chip. The chips 12 are all flat and are brazed to the V-shaped flat surface 13 of the base material 11 via a silver solder layer 14. Numerals 15 and 16 are grooves formed by the spacing between adjacent chips 12 and 12. Wire rod gripping surface 12 of upper and lower tips 12, 12
The angle of a and 12a (Fig. 9) is 90°, and the coil wire 1 with a circular cross section is drawn by a pair of drawing jaws 10 and 10.
can be grasped and held. Since the drawing jaw 10 repeatedly chucks the wire 1, the tip 12 wears quickly, and conventionally the tip 12 is made of cast steel, alloy steel, cemented carbide, or the like. However, in the conventional drawing jaw 10, as shown in FIGS. 8 and 9, a large number of flat cemented carbide chips 12 are simply brazed onto the flat surface 13 of the base material 11 using silver solder. Because of this, it is easy to separate during use. In other words, the current type has a wide brazing area, and the expansion coefficient of the component base material 11 is 11.5 x 10 -6 , while the expansion coefficient of the cemented carbide chip 12 is around 6 x 10 -6 , which is about half that of steel. . Therefore, stress remains due to the temperature difference between the solidification of the silver solder and room temperature, which is compounded with the repeated stress during chucking, and the excessive shear stress acting on the silver solder layer 14 causes the silver solder layer 14 to be destroyed at an early stage, resulting in chip failure. 12 breakaway accidents are likely to occur.
That is, although it is a well-known fact that cemented carbide is superior in terms of wear resistance, the reason why cemented carbide drawn jaws are not widely used is due to the above-mentioned circumstances.

る。 The process of providing the recess 19 in the base material 11 can be performed with high accuracy by using an NC multi-axis end mill. After processing a predetermined number of recesses 19, the base material 1
1 is subjected to heat treatment, and the entire surface including the gripping surface 18 is polished leaving a polishing allowance. Next, fit a circular piece of silver solder into the bottom of the recess 19, wrap a tape-shaped silver solder around each chip 20, fit it into the recess 19, press with appropriate paste, and align the surface of the chip 20 with the gripping surface 18. Subsequently, the base material 11 and chips 2 are placed on a brazing machine.
The drawn jaw 10 can be made by locally heating the bonding surface of the gripper 0 (by electric induction, etc.) to integrate the two, and then polishing the gripping surface 18.

い。 The cross-sectional shape of the drawing jaw according to the present invention may be a 104° V shape in addition to the 90° V shape shown in FIGS. If the cross-sectional shape of the wire is hexagonal, a 60° V-shaped gripping surface may be formed. When a wire with a rectangular or square cross section is gripped by a pair of drawing jaws, the gripping surface may be a flat surface. In both cases, part of the gripping surface is formed by a cemented carbide chip embedded in the recess.
Instead of the cemented carbide chip, a fine ceramic chip containing a large amount of zirconia may be used. Depending on the application, the surface (gripping surface) of the cemented carbide chip may be aligned so as to slightly protrude from the surface of the steel base material 11. In that case, the gripping force increases. The tip may be columnar or tapered.

れ、長期使用に耐える引抜ジヨーが得られる。(Effects of the invention) According to the invention, since the carbide chips are fitted and fixed in the recesses of the base material, even if the chips are subjected to excessive shearing force, they can be supported by the sides of the recesses of the base material. There is no risk of the chip peeling off from the base material.
Moreover, since the brazing area is smaller, residual stress is reduced, and from this aspect as well, detachment accidents are prevented, and a pull-out jaw that can withstand long-term use is obtained.
