Description

Technical Field

[0001] The utility model relates to the technical field of wire processing, in particular to a wire drawing machine for wire production. Background Art

[0002] The cable drawing machine is used to pull the cable during cable production. Some cable drawing machines in the prior art are of a clamp-type pulling structure. After completing a period of pulling, the device needs to drive the clamp back to the starting point to re-clamp the cable, and continuous pulling cannot be achieved.

[0003] The Chinese utility model patent application number is 202322186124.0. A cable pulling device uses two clamping cylinders to perform continuous cable pulling. However, when the pulling speed increases, the clamping cylinder needs to quickly reciprocate in the slide rail, and in order to avoid interference between the two clamping cylinders, when one clamping cylinder completes the pulling and moves in the opposite direction, it needs to give way backwards. These high-speed movements can easily cause damage to the equipment.

[0004] In addition, there is another potential problem that needs attention in the above patent, that is, the clamping cylinder is provided with a clamping claw, and the clamping force of the clamping claw on the cable is difficult to control. If it is clamped too tightly, it is easy to damage the cable, and if it is clamped too loosely, relative sliding is easy to occur, and friction will also occur between the cable skin.

DETAILED DESCRIPTION

[0022] The following is combined with Figure 1-4 The specific implementation modes of the present utility model are further described in detail.

[0023] Depend on Figure 1-4 The utility model provides a wire drawing machine for electric wire production, comprising a casing 10, two groups of rolling chain groups 20 symmetrically arranged on both sides of the casing 10, and a clamping mechanism 30 arranged between the two groups of rolling chain groups 20 for clamping cables. The rolling chain group 20 is a rolling belt structure driven by a motor, which can be a chain rolling belt or a belt rolling belt. The clamping mechanism 30 comprises a movable block 31 fixed on the rolling chain group 20, a clamping block 32 slidably arranged in the movable block 31 for clamping the cable, and a guide structure 33 arranged on the casing 10 for pushing the clamping block 32 inward. The movable block 31 is fixed to the rolling chain group 20 and can roll with the rolling chain group 20. When rolling, it will also drive the clamping block 32 to move. When working, When the cable is placed between the two groups of rolling chain groups 20, the rolling chain groups 20 drive the movable block 31 to move when rolling. When the movable block 31 moves to the position of the guide structure 33, the clamping blocks 32 between the two corresponding movable blocks 31 on the two groups of rolling chain groups 20 are close to each other and clamp the cable under the guiding action of the guide structure 33, so that the cable is pulled by the movement of the clamping blocks 32. When the movable block 31 moves to the end of the rolling chain group 20, the movable block 31 leaves the guide structure 33, and the cable is released from the clamping of the clamping blocks 32, and the next group of movable blocks 31 continues to enter the guide structure 33 and under the action of the guide structure 33, the next group of clamping blocks 32 clamps the cable and moves, thereby realizing continuous pulling of the cable.

[0024] A return spring 34 is connected between the clamping block 32 and the movable block 31. The guide structure 33 is an electromagnet 331 fixed on both sides of the upper end of the casing 10. A permanent magnet 35 that repels the electromagnet 331 is fixed at one end of the clamping block 32 close to the electromagnet 331. The movable block 31 rolls with the rolling chain group 20 and moves from one end of the guide structure 33 to the other end. When the movable block 31 enters the inner side of the electromagnet 331, the permanent magnet 35 is moved away from the electromagnet 331 and clamps the cable under the action of magnetic force. When the movable block 31 moves to the other end of the guide structure 33, the permanent magnet 35 loses the repulsive force of the electromagnet 331. Under the elastic force of the return spring 34, the clamping block 32 automatically releases the cable.

[0025] The magnetic force of the electromagnet 331 can be adjusted. Therefore, the clamping force of the clamping block 32 can be adjusted by adjusting the magnetic force of the electromagnet 331. For example, when there are many cables on the cable drum, a greater force is required to pull the cables. At this time, the clamping force can be increased by increasing the magnetic force of the electromagnet 331. When there are fewer cables on the cable drum, a smaller force can be used to pull the cables. At this time, the clamping force of the clamping block 32 can be reduced by reducing the magnetic force of the electromagnet 331.

[0026] In order to facilitate the judgment of whether the clamping force of the clamping block 32 is appropriate, the clamping block 32 is provided with a slip detection mechanism 40 for detecting whether slippage occurs between the clamping block 32 and the cable. In this embodiment, the slip detection mechanism 40 includes a detection wheel 41 rotatably installed on the inner side of the clamping block 32. The surface of the detection wheel 41 is a rubber structure, and the axis of the detection wheel 41 passes through the upper end of the clamping block 32, and a rotating block 42 is fixed to the upper end of the axis of the detection wheel 41. When the clamping block 32 clamps the cable, no slippage occurs between the cable and the clamping block 32, and the detection wheel 41 does not rotate at this time. When the clamping force of the clamping block 32 is insufficient, relative movement occurs between the clamping block 32 and the cable due to slippage. This relative movement causes the detection wheel 41 to roll on the surface of the cable, thereby causing the rotating block 42 to rotate. At this time, by observing the rotation of the rotating block 42, it can be known that the clamping force is insufficient, and the clamping force of the clamping block 32 can be increased by increasing the magnetic force of the electromagnet 331.

[0027] Cable guiding mechanisms 50 are provided at both ends of the housing 10 for guiding the horizontal movement of the cable, so that the cable pulling process is smoother.

[0028] In some embodiments, a base 11 is provided at the lower end of the housing 10 , and a telescopic structure 12 is connected between the base 11 and the housing 10 , and the height of the device can be adjusted through the telescopic structure 12 .

[0029] In some embodiments, the cable guiding mechanism 50 includes an upper guide wheel 51 and a lower guide wheel 52 rotatably mounted on the housing 10. The upper guide wheel 51 and the lower guide wheel 52 are both provided with guide grooves. When the cable is pulled, the cable is limited to move in the guide groove.

[0030] In some embodiments, the cable guiding mechanism 50 includes guiding tubes 53 fixed at two ends of the housing 10 , and the cables pass through between the guiding tubes 53 .

[0031] In this embodiment, the housing 10 is provided with two groups of mounting grooves 13 , and the two groups of rolling chain assemblies 20 are installed in the two groups of mounting grooves 13 . The inner wall of the mounting groove 13 is provided with a guide rail 14 , and the movable block 31 is slidably connected to the guide rail 14 .

[0032] The utility model is a wire drawing machine for electric wire production, the purpose of which is to realize continuous wire drawing of cables, and to timely adjust the clamping force of cables through electromagnets during the wire drawing process, so as to prevent the cables from being damaged due to excessive clamping force or from slipping and causing wear due to insufficient clamping force.
