DETAILED DESCRIPTION

[0015] The specific embodiments of the present invention are described in detail below with reference to the accompanying drawings.

[0016] like Figures 1 to 3 As shown, a device for fine-tuning the angle of wet-drawn steel wire feed die is provided, comprising a swivel seat 1 fixedly connected to a wet-drawing machine frame, a rotating box body 2 rotatably connected to the swivel seat 1, a straight tubular swinging member 3 suspended in the rotating box body 2, elastic support rods 4 respectively connected to the axial ends of the swinging member 3 and extending radially along the swinging member 3, adjusting screws 5 connected one-to-one to the free ends of each support rod 4 and extending axially outward along the support rod 4, and adjusting nuts 6 threadedly connected to the adjusting screws 5 one-to-one. The two support rods 4 are respectively arranged on both sides of the swinging member 3 and extend in opposite directions. The two adjusting screws 5 respectively pass through the opposite side walls of the rotating box body 2 and extend out of the rotating box body 2. The adjusting nut 6 is threadedly connected to the adjusting screw 5 outside the rotating box body 2. The rotation centerline of the rotating box body 2 passes through the center hole 301 of the swinging member 3. The rotating box body 2 is respectively provided with through holes 7 for the wet-drawn steel wire to pass through at both ends along the direction of its rotation centerline. A locking member 10 for locking the rotating box body 2 is provided on the swivel seat 1.

[0017] The central hole 301 of the swinging member 3 is lined with a wool felt core strip 8, and the steel wire 12 is passed through the wool felt core strip 8. The wool felt core strip 8 blocks the direct contact between the steel wire 12 and the swinging member 3, thereby preventing the steel wire 12 from being damaged by friction.

[0018] In this embodiment, the swivel seat 1 includes a base 101, a threaded hole 102 is provided on the upper end surface of the base 101, a connecting pipe 103 is connected to the threaded hole 102, the upper end of the connecting pipe 103 extends out of the threaded hole 102 and extends radially outward to form a retaining ring 104, and an annular groove 105 surrounding the outer surface of the connecting pipe 103 is formed between the retaining ring 104 and the upper end surface of the base 101. The connecting pipe 103 is inserted into a through hole 7 at the lower end of the rotating box 2, and the retaining ring 104 and the upper end surface of the base 101 rotate the bottom plate 2 of the rotating box 2. 01 clamping, the bottom plate 201 of the rotating box body 2 is rotatably connected in the card slot 105 through multiple bearings 9, and the base 101 is also provided with a wire hole 106 coaxial with the inner hole of the connecting pipe 103. The locking piece 10 is a screw, and the locking piece 10 passes through the base 101 and is threadedly connected to the base 101. The top of the locking piece 10 is opposite to the outer wall of the rotating box body 2. Twisting the locking piece 10 can make the top of the locking piece 10 tightly press against the rotating box body 2 to lock the rotating box body 2 or separate the top of the locking piece 10 from the rotating box body 2 to unlock the rotating box body 2.

[0019] In order to improve the connection strength between the rotating box body 2 and the swivel seat 1, the inner diameter of the through hole 7 at the bottom of the rotating box body 2 will be set relatively large, so that the inner diameters of the wire hole 106 and the connecting pipe 103 can be set relatively large, and a special tightening device can be inserted from the wire hole 106 to tighten the connecting pipe 103.

[0020] Although the connecting pipe 103 and the base 101 are threadedly connected in this embodiment, in actual production, the connecting pipe 103 and the base 101 may also be integrally formed, welded, clamped, or other various connection forms.

[0021] In this embodiment, the swinging member 3 is preferably a coil spring, with the spring wires at both ends extending radially outward in opposite directions to form two support rods 4. The coil spring itself has a certain degree of bending elasticity, and when the adjusting nut 6 is turned, the coil spring is more likely to oscillate and deform. At the same time, when the ends of the coil spring are subjected to tension, the inner diameter of the ends of the coil spring will slightly decrease, squeezing the wire 12 and thereby increasing the tension of the wire 12.

[0022] The adjusting nut 6 is provided with a dial 11 , through which the operator can quantitatively adjust the angle at which the steel wire 12 enters the mold 13 , thereby improving the adjustment accuracy.

[0023] The working principle of the present invention is: Figure 1 and Figure 3 As shown, the steel wire 12 passes through the swivel seat 1, the rotating box 2 and the swing member 3, and is then introduced into the mold 13. After being led out from the outlet end of the mold 13, it is connected to the traction mechanism (not shown in the figure). The traction mechanism pulls the steel wire 12 from bottom to top. When the finished steel wire downstream of the mold 13 has abnormal quality problems such as warping or bamboo knots, the locking member 10 is loosened, the rotating box 2 is rotated according to the characteristics of the warping or bamboo knots, and the adjusting nut 6 is rotated to make the swing member 3 deflect, as shown in FIG. Figure 3 As shown, the angle of the steel wire 12 entering the die is adjusted until the finished steel wire downstream of the die 13 returns to normal, and then the locking piece 10 is tightened to lock the rotating box 2.

[0024] During the wet drawing process of the steel wire, the die angle of the steel wire 12 may be adjusted multiple times.

[0025] The above embodiments are merely illustrative of the principles and effects of the present invention, as well as some embodiments of its application, and are not intended to limit the present invention. It should be noted that a person skilled in the art can make several modifications and improvements without departing from the concept of the present invention, and these modifications and improvements all fall within the scope of protection of the present invention.
