[0023] In order to make the above-mentioned purposes, features and advantages of the present invention more obvious and easy to understand, the specific implementation methods of the present invention are described in detail below in conjunction with the accompanying drawings.

[0024] Reference Figure 1-5 , is an embodiment of the utility model, which provides a wire crimping device for an enameled wire winding machine, the wire crimping device for an enameled wire winding machine comprises a workbench 1 and a control frame 2, the lower end of the control frame 2 is mounted on the upper surface of the workbench 1, a wire crimping tube 4 is arranged above the workbench 1 and on the left side of the control frame 2, a round tube 3 is arranged above the wire crimping tube 4, the upper end of the round tube 3 is fixedly mounted on the upper end of the control frame 2, the upper end of the wire crimping tube 4 and the lower end of the round tube 3 are both conical expansion shapes, and the ends of the wire crimping tube 4 and the round tube 3 close to each other are fixedly connected There are two arc-shaped raised blocks 8, and two rollers 9 are arranged inside the end where the wire pressing tube 4 and the circular tube 3 are close to each other. The raised position of the arc-shaped raised block 8 has a tendency to make the material line slide toward the roller 9, and the two ends of each roller 9 are rotatably connected to the adjacent arc-shaped raised blocks 8 respectively. The upper end of the wire pressing tube 4 drives the material line to bend, so that the distance between the upper end of the wire pressing tube 4 and the lower end of the circular tube 3 ensures that the material line will not bend at a large angle. The roller 9 reduces the friction between the material line and the lower end of the circular tube 3 and the upper end of the wire pressing tube 4, thereby reducing the wear of the material line.

[0025] The left and right sides of the wire pressing tube 4 are fixedly installed with an axle tube 5, the outer surface of the axle tube 5 is rotatably sleeved with a disc 11, the upper end of the disc 11 is fixedly connected with a bending rod 6, and an inner concave ring 7 is arranged above the wire pressing tube 4, the circular tube 3 is located at the inner ring side of the inner concave ring 7, the upper surface of the inner concave ring 7 is fixedly connected to the outer surface of the circular tube 3, the upper end of the bending rod 6 is slidably inserted in the inner ring surface of the inner concave ring 7, and the upper end of the bending rod 6 is vertical, and the two bending rods 6 are symmetrically distributed about the axis of the circular tube 3. The upper and lower ends of the bending rod 6 located inside the inner concave ring 7 are fixedly installed with friction beads 17, and the friction beads 17 increase the friction between the bending rod 6 and the inner concave ring 7, and increase the resistance of the bending rod 6 when sliding in the inner concave ring 7. Only after sufficient thrust is applied to the bending rod 6 can it move in the inner concave ring 7, so as to prevent the wire pressing tube 4 from swinging along the axis of the inner concave ring 7 due to the pulling force of the material line during winding.

[0026] A power air supply semi-ring 14 is arranged in front of the wire pressing tube 4, and a ventilation elbow 15 is rotatably inserted at one end of the two shaft tubes 5 away from each other, and the other end of the ventilation elbow 15 is fixedly inserted on the bottom surface of the power air supply semi-ring 14, and the upper surface of the power air supply semi-ring 14 is fixedly connected to the two bending rods 6. Ventilation holes 16 are opened on the inner walls on the left and right sides of the wire pressing tube 4, and the two ventilation holes 16 are respectively connected to the interior of the two shaft tubes 5, and the interiors of the two ventilation holes 16 are fixedly connected with elastic capsules 18. The power air supply semi-ring 14 inflates the shaft tube 5 to make the elastic capsule 18 expand and contact with the material line, thereby increasing the resistance when the material line moves and preventing the material line from being too loose.

[0027] A tooth groove 19 is provided on one side of the disc 11 away from the wire pressing tube 4, and a fixing plate 10 is provided on the side of the disc 11 away from the wire pressing tube 4. The fixing plate 10 is fixedly sleeved on the outer surface of the shaft tube 5.

One end of the push spring 12 is fixedly connected to the fixing plate 10, and the other end of the push spring 12 is fixedly connected to the pressure rod 13. The tooth groove 19 is a structure of multiple triangular grooves. The axis of the tooth groove 19 is coaxially arranged with the shaft tube 5. The two shaft tubes 5 are coaxially arranged. The push spring 12 has a tendency to push the pressure rod 13 to be inserted into the tooth groove 19, thereby increasing the resistance encountered by the shaft tube 5 when it rotates relative to the disc 11, and ensuring that when the material line is wound, the wire pressing tube 4 will not shake up and down due to the pulling of the material line. When a thrust is applied to the wire pressing tube 4 to drive the shaft tube 5 to rotate relative to the disc 11, the pressure rod 13 continuously compresses the push spring 12 by sliding on the inner wall of the triangular groove of the tooth groove 19.
