[0031] Example 1

[0032] Reference Figures 1-3 This first embodiment of the present invention proposes a device for preventing material slippage in a cold heading machine for fastener preparation. The device includes a mounting plate 1, with two sets of traction wheels 8 at the front end of the mounting plate 1. One end of each traction wheel 8 is provided with a first fixing block 15 and a second fixing block 16, and the other end of each traction wheel 8 is provided with an arc-shaped support block 7. A fixing plate 9 is fixedly connected to the front ends of the two sets of traction wheels 8. Two sets of baffles 10 are threadedly connected to the outer wall of each traction wheel 8. Several sets of evenly distributed threaded holes 19 are opened at the top end of each traction wheel 8. Bolts 18 are threadedly connected to both sets of baffles 10, and the output end of each bolt 18 is threadedly connected to the threaded hole 19. By setting two sets of baffles 10 threadedly connected to the surface of the traction wheel 8, the distance between the two sets of baffles 10 can be adjusted according to usage requirements. The baffles 10 are fixed by opening threaded holes 19 on the surface of the traction wheel 8 and setting bolts 18 on the baffles 10.

[0033] One set of the traction wheels 8 has a limiting groove 11. A cylinder 12 is fixedly connected to the front end of the mounting plate 1. A limiting block 13 is fixedly connected to the output end of the cylinder 12. The limiting block 13 is slidably connected to the limiting groove 11. A limiting rod 14 is fixedly connected to one end of the limiting block 13. The limiting rod 14 is slidably connected to the mounting plate 1. The limiting block 13 is moved horizontally by driving the cylinder 12. The limiting rod 14 is set to improve the stability of the movement of the limiting block 13. By controlling the limiting block 13 to insert into the limiting groove 11, the traction wheel 8 is limited, preventing the traction wheel 8 from rotating when cutting the material, which would cause the material to back up and improve the accuracy of the cutting length.

[0034] A motor 17 is fixedly connected to the rear end of the mounting plate 1. The output end of the motor 17 passes through the mounting plate 1 and is fixedly connected to another set of traction wheels 8. The material is moved by driving the other set of traction wheels 8 to rotate through the rotation of the motor 17.

[0035] The mounting plate 1 has two sets of sliding grooves 3, and electric push rods 4 are fixedly connected to both sets of sliding grooves 3. The output end of the electric push rod 4 is fixedly connected to a slider 5. One set of sliders 5 is fixedly connected to a stop block 6, and the other set of sliders 5 is rotatably connected to one set of traction wheels 8. By driving the electric push rod 4, the sliders 5 are driven to slide along the sliding groove 3. The height of the stop block 6 and the traction wheel 8 rotatably connected to one set of sliders 3 can be adjusted by controlling the sliders 5 to adjust the height of the sliders 5, so that the equipment can be adjusted according to the thickness of the material, which is beneficial to improving the practicality of the equipment.

[0036] In this embodiment, the electric push rod 4 drives the slider 5 to slide along the slide groove 3. The height of the block 6 and the traction wheel 8 rotatably connected to one of the sliders 3 are adjusted by controlling the slider 5. Two sets of baffles 10 are threadedly connected to the surface of the traction wheel 8, which facilitates the adjustment of the distance between the two sets of baffles 10 according to the usage requirements. The baffles 10 are fixed by threaded holes 19 on the surface of the traction wheel 8 and bolts 18 are set on the baffles 10, so that the equipment can be adjusted according to the thickness of the material, which is beneficial to improving the practicality of the equipment. The cylinder 12 drives the limit block 13 to move in the horizontal direction. The limit rod 14 is set to improve the stability of the movement of the limit block 13. The limit block 13 is controlled to insert into the limit groove 11 to limit the traction wheel 8, preventing the traction wheel 8 from rotating when cutting the material and causing the material to back up, which is beneficial to improving the accuracy of the cutting length.

[0038] Reference Figures 1-5This is the second embodiment of the present invention. The difference between this embodiment and the first embodiment is that: an arc-shaped support block 7 is fixedly connected to the front end of the mounting plate 1, and the arc-shaped support block 7 is correspondingly arranged with the abutment block 6; when the material is cut, the material is fixed by controlling the abutment block 6 to move closer to the arc-shaped support block 7 to prevent the material position from shifting.

[0039] The first fixing block 15 is fixedly connected to the mounting plate 1. The first fixing block 15 has a through hole 20. Two sets of first friction blocks 22 are slidably connected to the first fixing block 15. A steel wire is fixedly connected to the end of the two sets of first friction blocks 22 away from the first fixing block 15. An electric telescopic rod 21 is fixedly connected to the top and bottom of the inner wall of the first fixing block 15, respectively. The output end of the electric telescopic rod 21 is fixedly connected to the first friction block 22. By driving the electric telescopic rod 21, the first friction blocks 22 are moved closer or further apart, and the material is placed in the first fixing block 15.

[0040] The second fixing block 16 is fixedly connected to the mounting plate 1. The second fixing block 16 has a through hole 20. Two sets of second friction blocks 23 are slidably connected to the second fixing block 16. A steel wire is fixedly connected to one end of the two sets of second friction blocks 23 away from the second fixing block 16. Electric telescopic rods 21 are fixedly connected to the left and right ends of the inner wall of the second fixing block 16 respectively. The output end of the electric telescopic rod 21 is fixedly connected to the second friction blocks 23. By driving the electric telescopic rod 21, the second friction blocks 23 are moved closer or further apart, and the material is placed in the second fixing block 16.

[0041] The steel wires on the surfaces of the two sets of first friction blocks 22 and second friction blocks 23 are replaceable. The surfaces of the first friction blocks 22 and second friction blocks 23 are both provided with arc-shaped grooves to facilitate the fitting of the bar stock 2. The output end of the bar stock 2 passes through the first fixing block 15, the second fixing block 16 and the arc-shaped support block 7. The diameter of the bar stock 2 is smaller than the diameter of the through hole 20. By providing replaceable steel wires on the surfaces of the first friction blocks 22 and second friction blocks 23, it is convenient to remove rust and impurities from the surface of the bar stock 2, which helps to improve the production quality of this equipment.

[0042] In this embodiment, the material is fixed by controlling the abutment block 6 to approach the arc-shaped support block 7 to prevent the material position from shifting; the material is placed in the first fixed block 15 by driving the electric telescopic rod 21 to move the first friction blocks 22 closer or further apart; the material is placed in the second fixed block 16 by driving the electric telescopic rod 21 to move the second friction blocks 23 closer or further apart; replaceable steel wires are provided on the surfaces of the first friction blocks 22 and the second friction blocks 23 to facilitate the removal of rust and impurities from the surface of the bar stock 2, which helps to improve the production quality of this equipment; the first friction block 22 is used to clean the top and bottom outer walls of the bar stock 2, and the second friction block 23 is used to clean the left and right outer walls of the bar stock 2.
