Description

Technical Field

[0001] This utility model relates to the field of cable processing technology, specifically a mineral cable straightening device. Background Technology

[0002] Mineral-insulated cables (MI cables), also known as mineral-insulated cables, are high-performance cables with inorganic materials (such as magnesium oxide) as insulation and copper or copper alloys as conductors. They possess excellent fire resistance, high-temperature resistance, and mechanical strength, and are widely used in special environments such as high-temperature, high-humidity, flammable, and explosive environments.

[0003] However, traditional straightening devices have a relatively simple structure, with most having only one structure that squeezes from the top and bottom, resulting in poor straightening effect on cables. At the same time, because the outer sheath of the cable is relatively hard, it takes a long time to straighten and shape it, resulting in low straightening efficiency.

[0004] A mineral cable straightening device was proposed for this purpose. Utility Model Content

[0005] The purpose of this invention is to provide a mineral cable straightening device. A third servo motor drives a second bidirectional threaded rod to rotate, thereby moving a first threaded sleeve rod towards the center end. This causes the outer wall of the second roller to press tightly against the outside of the cable, compressing the upper and lower ends of the cable. Then, a fourth servo motor drives a third bidirectional threaded rod to rotate, thereby moving the second threaded sleeve rod towards the center end. This causes the outer wall of the third roller to press tightly against the outer wall of the cable, compressing both sides of the cable. This results in comprehensive compression of the cable's outer wall, leading to a better straightening effect.

[0006] To achieve the above objectives, the present invention provides the following technical solution: a mounting plate is fixedly connected to the middle of the upper surface of the workbench, and a heating box is fixedly connected to the side of the outer wall of the front end of the mounting plate near the first roller. The heating box has an installation cavity inside, and multiple copper rods are arranged inside the installation cavity. Each copper rod has multiple heating wires inside it.

[0007] Preferably, a first servo motor is fixedly connected to one side of the outer wall of the rear end of the mounting plate. A first bidirectional threaded rod is fixedly connected to the output end of the first servo motor.

A first roller is rotatably connected to the front end of each of the first threaded sleeves. A connecting plate is fixedly connected to one side of the upper first threaded sleeve. The front end of the connecting plate passes through the mounting plate to the front end of the mounting plate. A second servo motor is fixedly connected to the inner wall of the front section of the mounting plate. The output end of the second servo motor is fixedly connected to the first roller at the upper end. The second servo motor can drive the first roller to rotate, thereby moving the cable forward and reducing manpower.

[0008] Preferably, the mounting plate has multiple first sliding grooves in its middle, a third servo motor is fixedly connected to the middle of the lower surface of the workbench, the output end of the third servo motor passes through the workbench and is fixedly connected to the upper surface of the workbench with a second bidirectional threaded rod, a first threaded sleeve is fitted at both ends and the lower end of the second bidirectional threaded rod, a multiple first rotating rods are fixedly connected to the front end of each first threaded sleeve, a second roller is rotatably connected to the outside of each first rotating rod, a limiting rod is fitted on the side of the first threaded sleeve away from the first rotating rod, and the lower surface of the limiting rod is fixedly connected to the workbench. The stability of the first threaded sleeve can be improved by setting the limiting rod.

[0009] Preferably, a lifting plate is provided on the upper surface of the worktable away from the first servo motor. The upper surface of the lifting plate has multiple second sliding grooves.

A second rotating rod is fixedly connected to the upper surface of each second threaded sleeve. A third roller is rotatably connected to the outside of the second rotating rod. By setting the second rotating rod and the third roller, the two sides of the cable can be squeezed to improve its straightening effect.

[0010] Preferably, the inner wall of the heating box has multiple vent holes, one end of which extends through the inner wall of the mounting cavity. Pull-out plates are slidably connected to both sides of the heating box, and sealing strips are provided at the edges of the inner walls of each pull-out plate. A pull block is fixedly connected to the center of the front end of each pull-out plate. The pull-out plates are all made of aluminum foil composite material. A power supply is fixedly connected to the lower surface of the heating box, and both ends of the heating wire are connected to the positive and negative terminals of the power supply. The pull blocks allow the pull-out plates to be pulled out. The use of aluminum foil composite material further improves its heat preservation effect, and the positive and negative terminals ensure normal heating of the copper rod.

[0011] Preferably, each of the four corners of the lower surface of the workbench is fixedly connected to a support leg, and a support rod is fixedly connected between the front and rear ends of each support leg.

Then, the third bidirectional threaded rod is rotated by the fourth servo motor, thereby moving the second threaded sleeve rod towards the center end, so that the outer wall of the third roller is in close contact with the outer wall of the cable, and the two sides of the cable are squeezed. Thus, the outer wall of the cable is squeezed in all directions, and the straightening effect is better.

[0016] (2) This utility model reduces the straightening time and improves the straightening efficiency by softening the outer wall of the cable through the internal copper rod and heating wire when the cable passes through the heating box before straightening. It is highly practical. Attached Figure Description

Example

[0025] Existing straightening devices have a relatively simple structure, mostly consisting of only an upper and lower compression mechanism, resulting in poor straightening effect on cables. Furthermore, due to the hardness of the cable sheath, a prolonged straightening process is required for proper shaping, leading to low straightening efficiency.

[0033] In use, the second servo motor 35 drives the first roller 33 to rotate, thereby moving the cable forward and reducing manual labor. Then, the cable softens its outer wall by passing through the copper rod 42 and heating wire 421 inside the heating box 4. The cable continues to move forward, and the third servo motor 51 drives the second bidirectional threaded rod 52 to rotate, thereby moving the first threaded sleeve rod 53 towards the center end. This causes the outer wall of the second roller 55 to press tightly against the outside of the cable, compressing the upper and lower ends of the cable. Then, the fourth servo motor 62 drives the third bidirectional threaded rod 63 to rotate, thereby moving the second threaded sleeve rod 64 towards the center end. This causes the outer wall of the third roller 66 to press tightly against the outer wall of the cable, compressing both sides of the cable. This comprehensive compression of the cable's outer wall improves the straightening effect and heats the outside of the cable, reducing straightening time and increasing straightening efficiency, making it highly practical.
