Abstract
Description
Technical Field
[0001] The utility model relates to a wire drawing machine, in particular to a movable wire dividing mechanism in the wire drawing machine. Background Art
[0002] In a wire drawing machine, in order to enable metal wire rods to obtain a uniform annealing temperature, a wire dividing mechanism is required to neatly arrange the metal wire rods on a nickel pulley in a certain order and direction. Due to the fixed guiding effect of the wire dividing mechanism on the metal wire rods, the contact position between the metal wire rods and the nickel pulley remains unchanged. When the metal wire rods move, they only contact and rub against the fixed positions of the nickel pulley, which will accelerate the wear of the nickel pulley. The worn nickel pulley will not only affect the annealing effect but also cause damage to the metal wire rods. Summary of the Utility Model
[0003] The purpose of the utility model is to provide a movable wire dividing mechanism in a wire drawing machine, which reduces the wear rate between the metal wire rods and the nickel pulley by laterally swinging the metal wire rods.
[0004] To achieve the above purpose, the technical solution adopted by the utility model is: a movable wire dividing mechanism in a wire drawing machine, comprising: a fixed seat, a stepping motor is arranged in the fixed seat, an eccentric wheel is arranged on the stepping motor, a fixed shaft is horizontally arranged in the fixed seat, a left linear bearing and a right linear bearing are slidably arranged on the fixed shaft, a retaining sleeve is fixedly arranged on the fixed shaft between the left linear bearing and the right linear bearing, a spring is sleeved on the fixed shaft between the retaining sleeve and the left linear bearing, and two ends of the spring respectively abut against the left linear bearing and the retaining sleeve. A bolt bearing is arranged on the left linear bearing, and the bolt bearing abuts against the eccentric wheel. An installation plate is arranged between the left linear bearing and the right linear bearing, and two rows of magnetic rods are arranged on the installation plate. The magnetic rods in the rear row are arranged in a dislocation manner with respect to the magnetic rods in the front row, and the distance between the magnetic rods in the rear row and the left and right adjacent magnetic rods in the front row is the wire diameter of the metal wire rod.
[0005] Further, for the aforesaid movable wire dividing mechanism in a wire drawing machine, a threaded post is arranged on the magnetic rod, and a threaded hole is arranged on the installation plate. The threaded post on the magnetic rod is threadedly connected with the threaded hole on the installation plate.
[0006] Further, for the aforesaid movable wire dividing mechanism in a wire drawing machine, the eccentricity of the eccentric wheel is 3 mm - 4 mm.
[0007] Further, for the aforesaid movable wire dividing mechanism in a wire drawing machine, a plurality of first set screws are arranged on the retaining sleeve, and the first set screws abut against the fixed shaft.
[0008] Further, for the aforesaid movable wire dividing mechanism in a wire drawing machine, a retaining ring is arranged on the right end wall of the left linear bearing, and the spring abuts against the retaining ring.
[0009] Furthermore, in the movable wire dividing mechanism of the above-mentioned wire drawing machine, a protective baffle is provided on the fixed seat.
[0010] Furthermore, in the movable wire dividing mechanism of the above-mentioned wire drawing machine, the left linear bearing does not contact the fixed seat.
[0011] Furthermore, when the fixed shaft is inserted into the fixed seat, a second set screw is threadedly connected to the fixed seat, and the second set screw abuts against the fixed shaft.
[0012] The advantages of the present utility model are as follows: The eccentric wheel is driven by a stepper motor to rotate and act on the bolt bearing. When the long diameter end of the eccentric wheel abuts against the bolt bearing, the left linear bearing connected to the bolt bearing slides to the right against the elastic force of the spring. When the short diameter end of the eccentric wheel abuts against the bolt bearing, the left linear bearing connected to the bolt bearing slides leftward to reset under the elastic force of the spring, thereby realizing the left and right sliding of the left linear bearing. The cooperation of the left linear bearing and the right linear bearing can drive the mounting plate and the magnetic rod on the mounting plate to swing left and right, so that the metal wire passing through the magnetic rod swings left and right together, thus preventing the metal wire from rubbing against the same part of the nickel pulley and accelerating the wear of the nickel pulley. Description of the Drawings
[0013] Figure 1 It is a schematic structural diagram of the movable wire dividing mechanism in the wire drawing machine described in the present utility model.
[0014] Figure 2 It is Figure 1 a schematic structural diagram in the top view direction. Detailed Embodiments
[0015] The technical solution of the present utility model will be further described below in conjunction with the drawings and preferred embodiments.
[0016] As Figure 1 、 Figure 2As shown in the figure, the movable wire dividing mechanism in the wire drawing machine of the present utility model includes: a fixed seat 1, the fixed seat 1 is connected to the side wall of the wire drawing machine by bolts, a stepping motor 11 is arranged in the fixed seat 1, a guard board 12 is arranged on the fixed seat 1, and the guard board 12 plays a protective role for the stepping motor 11. An eccentric wheel 13 is arranged on the stepping motor 11, and the eccentricity of the eccentric wheel 13 is 3 mm to 4 mm. A fixed shaft 2 is horizontally inserted in the fixed seat 1, and a second set screw 14 is threadedly connected to the fixed seat 1, and the second set screw 14 abuts against the fixed shaft 2. A left linear bearing 21 and a right linear bearing 22 are slidably arranged on the fixed shaft 2. In actual use, the linear bearing will not rotate on the shaft. Once it rotates, the linear bearing will be damaged. Therefore, in this embodiment, the left linear bearing 21 and the right linear bearing 22 are directly slidably arranged on the fixed shaft 2, and there is no need to additionally use a guide post for positioning. A retaining ring 211 is arranged on the right end wall of the left linear bearing 21. A retaining sleeve 23 is fixedly arranged on the fixed shaft 2 between the left linear bearing 21 and the right linear bearing 22. A number of first set screws 231 are arranged on the retaining sleeve 23, and the first set screws 231 abut against the fixed shaft 2. A spring 24 is sleeved on the fixed shaft 2 between the retaining sleeve 23 and the left linear bearing 21, and the two ends of the spring 24 respectively abut against the retaining ring 211 and the retaining sleeve 23 to prevent the spring 24 from being caught in the left linear bearing 21 and causing damage to the left linear bearing 21. By adjusting the position of the retaining sleeve 23, the compression amount of the spring 24 can be adjusted. When the elastic force of the spring 24 decreases, the elastic force of the spring 24 can be increased by moving the position of the retaining sleeve 23, so as to ensure that the spring 24 has a stable elastic force. A bolt bearing 3 is arranged on the left linear bearing 21, and the bolt bearing 3 abuts against the eccentric wheel 13. Under the abutting action between the bolt bearing 3 and the eccentric wheel 13, the left linear bearing 21 does not collide with the fixed seat 1. An installation plate 4 is arranged between the left linear bearing 21 and the right linear bearing 22. Two rows of magnetic rods 41 are arranged on the installation plate 4, and the magnetic rods 41 in the rear row are arranged in a staggered manner with the magnetic rods 41 in the front row. The distance h between the magnetic rods 41 in the rear row and the left and right adjacent magnetic rods 41 in the front row is the wire diameter of the metal wire. Threaded posts are arranged on the magnetic rods 41, and threaded holes are arranged on the installation plate 4. The threaded posts on the magnetic rods 41 are threadedly connected to the threaded holes on the installation plate 4. In this way, when dividing wires of different wire diameters of metal wires, only the magnetic rods 41 of different diameters need to be replaced.
[0017] The metal wire passes through the spacing h between the front and rear rows of magnetic rods 41 and then is wound around the nickel pulley. The front and rear rows of magnetic rods 41 with a spacing of h play a role in clamping and separating the metal wire. Then, the stepping motor 11 is started to drive the eccentric wheel 13 to rotate. When the long diameter end of the eccentric wheel 13 acts on the bolt bearing 3, it will exert a pushing force on the bolt bearing 3, causing the left linear bearing 21 to move to the right against the elastic force of the spring 24, thereby driving the mounting plate 4 and the right linear bearing 22 to move to the right together. When the short diameter end of the eccentric wheel 13 acts on the bolt bearing 3, the left linear bearing 21 will reset to the left under the elastic force of the spring 24, driving the mounting plate 4 and the right linear bearing 22 to move to the left together. Moreover, the left linear bearing 21 does not collide with the fixed seat 1 to generate noise. Since the eccentricity of the eccentric wheel 13 is 3 mm to 4 mm, when the eccentric wheel 13 drives the mounting plate 4 to swing left and right through the bolt bearing 3, the swing amplitude of the mounting plate 4 is between 3 mm and 4 mm. And the metal wire clamped by the two rows of magnetic rods 41 will swing left and right together with the mounting plate 4. The metal wire will swing on the nickel pulley with a swing amplitude of 3 mm to 4 mm, preventing the metal wire from rubbing against the same part of the nickel pulley and accelerating the wear of the nickel pulley.

Although the present invention has been described in detail with reference to the above embodiments, those of ordinary skill in the art should understand that: still modifications or equivalent substitutions can be made to the specific embodiments of the present invention.
