Description

Technical Field

[0001] The invention relates to the field of electric wire manufacturing, and in particular to a method for manufacturing a double-row wire. Background Art

[0002] As the name implies, a double-row cable is made by connecting two wires side by side. There is a double-row cable, such as a fluoroplastic polymer insulated double-row cable. Specifically, the manufacturing method includes first using a fluoroplastic polymer extruder to extrude two fluoroplastic polymer insulated wires spaced apart and arranged side by side. When the two fluoroplastic polymer insulated wires just leave the fluoroplastic polymer extruder, the temperature is relatively high and they need to enter a cooling water tank located next to the fluoroplastic polymer extruder for cooling. After passing through the cooling water tank, the two fluoroplastic polymer insulated wires have been cooled to a relatively low temperature state and are then manually bonded together with glue. After the glue solidifies, the desired fluoroplastic polymer insulated double-row cable is obtained. However, this manufacturing method is inefficient, and the obtained fluoroplastic polymer insulated double-row cable is easy to debond and separate due to the use of glue for bonding, and has a short service life. Summary of the invention

[0003] The technical problem to be solved by the present invention is to provide a double-row cable manufacturing method, by which the double-row cables can be manufactured efficiently, and the manufactured double-row cables are not easy to separate and have a long service life.

[0004] In order to solve the above problems, the present invention provides a method for manufacturing a double-row cable, which uses a cooling water trough, and the cooling water trough is provided with an inlet and an outlet. An extruder is used to extrude two hot electric wires that are parallel and spaced from each other into the inlet of the cooling water trough. The two electric wires enter the cooling water trough through the inlet of the cooling water trough for cooling, and move forward in parallel along the cooling water trough until they pass through the outlet of the cooling water trough in parallel. A deflection device is used to deflect the two electric wires that are moving forward in parallel along the cooling water trough from being spaced from each other to being close to each other, so that the two electric wires are melted together by their own residual heat to produce a double-row cable.

[0005] Furthermore, the deflection guide device is specifically installed on the cooling water trough so that the deflection guide device extends into the cooling water trough.

[0006] Furthermore, after the deflection guide device is installed, the position of the deflection guide device extending into the cooling water tank is adjusted.

[0007] Furthermore, three deflection guide devices are specifically used, and the three deflection guide devices are arranged in a front-to-back manner with intervals.

[0008] Furthermore, the extruder is used to extrude two vertically parallel electric wires, and the positions of the three deflection guide devices are adjusted so as to deflect the two electric wires in the cooling water tank in the vertical direction.

[0009] Furthermore, the extruder is specifically a fluoroplastic polymer extruder, the electric wire is specifically a fluoroplastic polymer insulated electric wire, and the double-row wire is specifically a fluoroplastic polymer insulated double-row wire.

[0010] Beneficial effect: In the process of cooling the wires, the manufacturing method uses a deflection guide device to make two spaced hot wires close together to promote the two wires to be welded together by residual heat, without waiting for the wires to cool to room temperature and then manually gluing the two wires together as in the prior art. Therefore, the manufacturing method can be used to efficiently manufacture double-row wires, and the double-row wires made by welding are not easy to separate and have a long service life.

DETAILED DESCRIPTION

[0020] The present invention is further described in detail below in conjunction with specific implementation methods.

[0021] Double row line manufacturing equipment 1 Figure 2 , including a fluoroplastic polymer extruder 11 and a cooling water trough 2, wherein the notch of the cooling water trough 2 faces upward and the trough is filled with cooling water. The side wall of the rear trough of the cooling water trough 2 is provided with an inlet 21 and the side wall of the front trough is provided with an outlet 22, and the fluoroplastic polymer extruder 11 extrudes two fluoroplastic polymer insulated wires 31 and 32 arranged side by side and spaced from each other toward the inlet 21 of the cooling water trough 2. The two fluoroplastic polymer insulated wires 31 and 32 are at a very high temperature when they just leave the fluoroplastic polymer extruder 11 and need to be cooled, so they enter the cooling water trough 2 through the inlet 21, move side by side along the cooling water trough 2, and are cooled by the cooling water in the cooling water trough 2, and finally pass through the outlet 22 of the cooling water trough 2 side by side. The existing cooling water tank 2 is usually equipped with a cooling water circulation device (not shown in the figure), which includes a water reservoir (not shown in the figure) and a water return mechanism (not shown in the figure) provided at the outlet 22 of the cooling water tank 2. After the cooling water in the cooling water tank 2 exchanges heat with the fluoroplastic polymer insulated wires 31 and 32, it overflows from the inlet 21 of the cooling water tank 2 to the outside of the tank and flows into the water reservoir for natural heat dissipation and cooling, and then is drawn by the water return mechanism and sent back to the cooling water tank 2. In this way, the cooling water level in the cooling water tank 2 is higher than the lowest point of the inlet 21, and can continuously immerse the two fluoroplastic polymer insulated wires to be cooled in the cooling water tank, and can continuously bring the heat in the cooling water tank 2 out of the tank. Providing a cooling water circulation device for the cooling water tank 2 to achieve a cooling effect is a conventional technical means in the art, and the specific structure of the device is not described here.

[0022] See Figure 1 and Figure 2 Three deflection guides 4, 5, 6 are installed on the top surface of the side wall of the cooling water trough 2. The three deflection guides 4, 5, 6 are arranged at intervals along the cooling water trough 2, and each extends into the cooling water trough 2 to deflect the two fluoroplastic polymer insulated wires 31, 32 in the cooling water trough 2 that are moving in parallel along the cooling water trough 2 from the upper and lower intervals to each other and close to each other. In this way, since the two fluoroplastic polymer insulated wires 31, 32 have not been completely cooled, the two fluoroplastic polymer insulated wires 31, 32 that are close to each other are gradually melted together under the action of their own residual temperature. After that, the two fluoroplastic polymer insulated wires 31, 32 continue to move along the cooling water trough 2 while maintaining the state of being melted together and are cooled by cooling water. When the two fluoroplastic polymer insulated wires 31, 32 pass through the outlet 22 of the cooling water trough 2, the two fluoroplastic polymer insulated wires 31, 32 are cooled to a lower temperature state and are completely melted together to form a fluoroplastic polymer insulated double-row wire.

[0023] The deflection guide devices 4, 5, and 6 have the same structure. Taking the deflection guide device 4 at the rear as an example, see Figure 4 and Figure 6 The deflection guide device 4 includes a round rod-shaped body 41. The rod-shaped body 41 is in a "Z" shape. The axis of the starting end 411 of the rod-shaped body 41 is parallel to the axis of the terminal end 412 of the rod-shaped body 41 but not colinear. A bearing 421 is provided at the terminal end 412 of the rod body. The bearing 421 covers the terminal end 412 of the rod body and can move along the axis of the terminal end 412 of the rod body. A guide ring 43 is sleeved on the outer side of the bearing 421 to form a guide wheel mechanism. The guide ring 43 is sleeved on the terminal end 412 of the rod body through the bearing 421 and is driven by the bearing 421 to move along the axis of the terminal end 412 of the rod body and rotate around the axis of the terminal end 412 of the rod body. A limiting annular groove 431 is provided along the circumference of the guide ring 43. The fluoroplastic polymer insulated wire passing tangentially is trapped in the limiting annular groove 431 to be limited and guided. See Figure 6 and Figure 7 A locking part 422 is provided at each end of the bearing 421. The two locking parts 422 have the same structure and are respectively blocked at the two ends of the bearing 421. The center of each locking part 422 is left empty and is sleeved on the end part 412 of the rod body, and can move along the axis of the end part 412 of the rod body and rotate around the axis of the end part 412 of the rod body. A radial threaded hole 423 leading to its own axis is opened on the outer wall of the locking part 422 and a bolt 424 is provided. The bolt 424 is rotated and screwed into the threaded hole 423 to support the side wall of the end part 412 of the rod body, and the locking part 422 locks the end part 412 of the rod body in this way so that it cannot rotate or move relative to the end part 412 of the rod body; when unlocking is required, the bolt 424 is rotated and screwed out along the threaded hole 423 until it leaves the side wall of the end part 412 of the rod body, and the locking part 422 no longer locks the end part 412 of the rod body, and can move along the axis of the beginning part 411 of the rod body and rotate around the axis of the beginning part 411 of the rod body. In this way, the two locking parts 422 are locked to the rod body end part 412 through their own bolts 424, and the bearings 421 are blocked and clamped at both ends of the bearing 421, so that the bearing 421 is detachably locked to the end part 412. The bearing 421, the two locking parts 422 and the two bolts 424 together constitute the bearing seat 42 for the guide ring 43 to be installed on the rod body end part 412, and the bearing seat 42 is a split structure.

[0024] See Figure 4 and Figure 5A mounting seat 44 is provided at the beginning 411 of the rod body, and a through hole 441 is provided on the mounting seat 44 along the axis of the beginning 411 of the rod body. The beginning 411 of the rod body passes through and is accommodated in the through hole 441, and can move along its own axis relative to the mounting seat 44 and rotate around its own axis. A locking threaded hole 442 is provided on the top surface of the mounting seat 44, which is connected to the through hole 441 and is provided with a locking bolt 443. The locking bolt 443 is rotated and screwed into the locking threaded hole 442 to press against the side wall of the beginning 411 of the rod body, thereby locking the beginning 411 of the rod body, and the beginning 411 of the rod body cannot rotate or move relatively; when unlocking is required, the locking bolt 443 is rotated and screwed out along the locking threaded hole 442 until it leaves the side wall of the beginning 411 of the rod body, and the beginning 411 of the rod body is no longer locked by the mounting seat 44, and can move along its own axis relative to the mounting seat 44 and rotate around its own axis.

[0025] The mounting seat 44 is detachably connected to the top surface of the cooling water tank 2 by bolts (not shown in the figure), and the guide device 4 is installed on the cooling water tank 2. The rod end 412 of the guide device 4, together with the bearing seat 42 and the guide ring 43 installed thereon, extends into the cooling water tank 2. The guide device 4 at the rear, the guide device 5 at the center, and the guide device 6 at the front have the same structure, and only the positions on the top surface of the cooling water tank 2 are different. The three guide devices 4, 5, 6 are shown in FIG. Figure 3After being installed on the cooling water trough 2 as shown, the operator installs the cooling water trough 2 together with the three deflection guide devices 4, 5, 6 installed on the cooling water trough 2 to the front of the fluoroplastic polymer extruder 11, and then the two fluoroplastic polymer insulated wires 31 and 32 passing through the cooling water trough 2 can be deflected by the three deflection guide devices 4, 5, 6 on the cooling water trough 2. Before deflection, the operator needs to adjust the position of the guide rings 43, 53, 63 of each deflection guide device 4, 5, 6. Taking the deflection guide device 4 at the rear as an example, first, the operator loosens the locking bolt 443 of the mounting seat 44 of the deflection guide device 4 so that it no longer locks the beginning 411 of the rod body. After that, the operator holds the beginning 411 of the rod body and moves it relative to the mounting seat 44 along its own axis, thereby driving the end 412 of the rod body and the guide ring 43 installed thereon to move together until the limiting ring groove 431 of the guide ring 43 is aligned with the fluoroplastic polymer insulated wires 31 and 32 passing through the cooling water trough 2. Then, the operator twists the beginning portion 411 of the rod body to rotate it around its own axis relative to the mounting seat 44, driving the end portion 412 of the rod body to rotate together, and the guide ring 43 installed on the end portion 412 of the rod body rises or falls relative to the cooling water tank 2. The guide ring 43 moves to the desired position. After the guide ring 43 is in place, the operator needs to tighten the locking bolt 443 of the mounting seat 44 of the guide device to rotate it and screw it into and support the side wall of the beginning portion 411 of the rod body, thereby locking the beginning portion 411 of the rod body. The end portion 412 of the rod body is also locked. In this state, the operator can fine-tune the position of the guide ring 43 by loosening or tightening the bolt 424 of the bearing seat 42 provided on the end portion 412 of the rod body. The adjustment operation method of the other two guide devices 5 and 6 is the same as that of the guide device 4 at the rear. After adjustment, the positions of the guide rings 43, 53, and 63 of the guide devices 4, 5, and 6 are as shown in FIG. Figure 2As shown: the guide ring 43 of the guide device at the rear uses the upper groove surface of the limiting ring groove 431 to stick to and lift up the fluoroplastic polymer insulated wire 32 at the bottom, that is, the fluoroplastic polymer insulated wire 32 at the bottom is guided upward to make it close to the fluoroplastic polymer insulated wire 31 at the top, and the distance between the two fluoroplastic polymer insulated wires 31 and 32 is reduced; the guide ring 53 of the guide device 5 in the middle uses the lower groove surface of the limiting ring groove 531 to stick to and press the fluoroplastic polymer insulated wire 31 at the top, that is, the fluoroplastic polymer insulated wire 31 at the top is guided downward to make it close to the fluoroplastic polymer insulated wire 32 at the bottom, and the distance between the two fluoroplastic polymer insulated wires 31 and 32 is further reduced; the guide ring 63 of the guide device 6 at the front uses the upper groove surface of the limiting ring groove 631 to stick to and lift up the fluoroplastic polymer insulated wire 32 at the bottom, that is, the fluoroplastic polymer insulated wire 32 at the bottom is guided upward for a second time to make it completely stick to the fluoroplastic polymer insulated wire 31 at the top. Since the temperature of the two fluoroplastic polymer insulated wires 31, 32 is still relatively high when they are pressed against each other and close together, the two fluoroplastic polymer insulated wires 31, 32 are melted together under the action of their own residual heat. The two melted fluoroplastic polymer insulated wires 31, 32 continue to move forward in parallel and are gradually cooled by cooling water in the process of going to the outlet 22 of the cooling water tank 2, thereby obtaining the required fluoroplastic polymer insulated double-row wire.

[0026] The cooling water tank 2 and the three deflection guides 4, 5, 6 installed thereon together constitute a cooling device. In this embodiment, the fluoroplastic polymer extruder 11 extrude two hot fluoroplastic polymer insulated wires 31, 32 that are arranged side by side and spaced from each other toward the inlet 21 of the cooling water tank 2, and the three deflection guides 4, 5, 6 deflect the two fluoroplastic polymer insulated wires 31, 32 in the up-down direction. In other embodiments, the fluoroplastic polymer extruder 11 can be changed to extrude two hot fluoroplastic polymer insulated wires that are arranged side by side and spaced from each other, and the deflection guides need to be changed accordingly to deflect the two fluoroplastic polymer insulated wires in the left-right direction.

[0027] In this embodiment, the rod body start end portion 411 of the deflection guide device is provided with a mounting seat 44 to serve as a mounting portion for mounting with the cooling water tank 2. In other embodiments, the rod body start end portion 411 may not be provided with a mounting seat 44 but may be directly welded to the top surface of the cooling water tank 2. In this case, the rod body start end portion 411 serves as a mounting portion for installation.

[0028] In this embodiment, the guide ring 43 of the deflection guiding device is used as a deflection guiding part for deflecting the fluoroplastic polymer insulated wires 31 and 32, and is installed on the rod body end portion 412, and can rotate around the axis of the rod body end portion 412. In other embodiments, the guide ring 43 can be replaced by a fixed arc-shaped protrusion that cannot rotate, and the deflection of the fluoroplastic polymer insulated wires 31 and 32 can be guided through the arc surface top of the arc-shaped protrusion.

[0029] The above is only an implementation method of the invention, and does not limit the scope of patent protection. Those skilled in the art can make non-substantial changes or substitutions based on the invention, which still fall within the scope of patent protection.
