Description

Technical Field

[0001] The utility model relates to the technical field of tight compression and film drawing devices, in particular to a cooling component and a tight compression and film drawing device. Background Art

[0002] The cable conductor compression production generally uses the compression drawing method, which means that multiple single wires pass through the compression die hole and undergo plastic deformation under a certain tensile force, which reduces their cross-section and increases the filling factor, reduces the contact resistance, and makes the conductor surface smooth. The inner hole of the compression drawing die consists of four areas: the entrance area, the deformation area, the sizing area, and the safety area. The deformation area generates the most heat among these four areas. The conductor changes from large to small in this area and the inner hole of the die. The wire diameter also changes from large to small. The stretching energy consumption is large and the deformation body is subject to certain restrictions. Therefore, it is often necessary to use a compression drawing die for each layer.

[0003] When the wire passes through the tight drawing die, friction will generate heat, which will cause the wire temperature to be too high and oxidize and discolor, causing the resistance value to fluctuate.

[0030] See also Figures 1 to 3The utility model provides a cooling component 1 for cooling a compression film drawing component 2. The cooling component 1 includes a shell 11. A receiving cavity 111 is formed inside the shell 11. The receiving cavity 111 is used to receive cooling water. The shell 11 also has a receiving groove 113. There are two shells 11. The two shells 11 are connected to each other so that the two receiving grooves 113 are connected to each other to form an installation position. The installation position is used to install the compression film drawing component 2. Specifically, during production, the operator first fills the accommodating chamber 111 with cooling water, then splices the two outer shells 11 to form an installation position, installs the compression and stretching film assembly 2 at the installation position, and the compression and stretching film assembly 2 abuts against the inner wall of the accommodating groove 113, then starts the compression and stretching film assembly 2, and feeds multiple wires of the conductor into the compression and stretching film assembly 2, so that the compression and stretching film assembly 2 will compress the wires, and the multiple wires will be subjected to tension and pressure. Under a certain tension, the multiple wires will undergo plastic deformation to form conductors in the cable. During the compression process, the compression and stretching film assembly 2 and the wires will rub against each other, and the friction will generate heat. At this time, the heat generated by the friction will be transferred from the compression and stretching film assembly 2 to the cooling water in the accommodating chamber 111 through the outer shell 11, so that the temperature of the compression and stretching film assembly 2 will be reduced, and the wires will be prevented from being oxidized due to excessive temperature; at the same time, reducing the temperature of the compression and stretching film assembly 2 can also prevent the mold in the compression and stretching film assembly 2 from thermal expansion and contraction, and prevent the outer diameter of the conductor from becoming larger.

[0031] See also Figures 1 to 3 In one embodiment, the cooling assembly 1 further includes a water pump 13 and a water tank 14. The housing 11 is formed with a water outlet 112 and a water inlet 114. The water outlet 112 and the water inlet 114 are both connected to the accommodating chamber 111. The water inlet end of the water pump 13 is connected to the water tank 14, the water outlet end of the water pump 13 is connected to the water inlet 114, and the water tank 14 is connected to the water outlet 112. Specifically, during the production process, the water pump 13 continuously pumps the already heated cooling water in the accommodating chamber 111 from the water outlet 112 to the water tank 14, and then pumps the cooling water in the water tank 14 from the water inlet 114 to the accommodating chamber 111, so that the cooling water in the accommodating chamber 111 can always be kept at a low temperature, which can improve the cooling efficiency.

[0032] See also Figures 1 to 3In one embodiment, the receiving groove 113 includes a first sub-receiving groove 113a and a second sub-receiving groove 113b.

Under a certain tension, the multiple wires will undergo plastic deformation to form the conductor in the cable, and the conductor extends from the compression film assembly 2 to the second sub-containing groove 113b, and then is transported to the next process. Through such a setting, the compression film assembly 2 can have a larger area in contact with the outer shell 11, so that the compression film assembly 2 can be cooled faster, and by setting the second sub-containing groove 113b, the conductor can be produced normally, and there will be no collision between the conductor and the outer shell 11.

[0033] See also Figures 1 to 3 In one embodiment, the walls of the first sub-accommodating groove 113a and the second sub-accommodating groove 113b are both arc-shaped.

[0034] See also Figures 1 to 3 In one embodiment, the first sub-accommodating groove 113a and the second sub-accommodating groove 113b are concentrically arranged and of different sizes to form a step. By such a coaxial arrangement, the straightness of the conductor can be ensured when it is produced, and the conductor will not collide with the shell 11 due to the excessive eccentricity between the first sub-accommodating groove 113a and the second sub-accommodating groove 113b; and the concentric arrangement is more efficient when producing the shell 11, and no other production molds are required, which greatly reduces the production cost.

[0035] See also Figures 1 to 3 In one embodiment, the cooling assembly 1 further includes a water outlet connecting pipe 15 and a water inlet connecting pipe 16, the two ends of the water outlet connecting pipe 15 are respectively connected to the water outlet 112 and the water pump 13, and the two ends of the water inlet connecting pipe 16 are respectively connected to the water inlet 114 and the water storage tank 14.

[0039] See also Figures 1 to 3 In one embodiment, the housing 11 is further formed with a drain hole 18 that is interconnected with the accommodating chamber 111, and the cooling assembly 1 further includes a sealing cover that is mounted on the drain hole 18. By providing the drain hole 18, when the cooling water in the accommodating chamber 111 is at a high temperature and cannot be cooled quickly, the operator opens the sealing cover to drain the cooling water in the accommodating chamber 111, and then injects new low-temperature cooling water to cool again, so that the cooling effect can be maintained.

[0040] According to another aspect of the utility model, the utility model also provides a compression film drawing device 100, including a compression film drawing component 2, a control component and the above-mentioned cooling component 1, wherein the control component is respectively connected to the compression film drawing component 2 and the water pump 13 by signal, and the compression film drawing component 2 is sleeved on the installation position. By setting the control component, the operating speed of the compression film drawing component 2 and the water pump 13 can be controlled at the same time, so that the flow speed of the cooling water in the accommodating chamber 111 is coordinated with the production speed of the compression film drawing component 2, so that the compression film drawing component 2 can be kept at a normal temperature for a long time, which can improve the quality of the product. Since the compression film drawing device 100 includes all implementation methods of all embodiments of the above-mentioned cooling component 1, it has at least all the beneficial effects brought by all the above-mentioned implementation methods, which will not be repeated here one by one.
