Embodiment 1

[0036] Such as Figure 3-Figure 4 As shown, a cable aluminum sheath continuous coating mold replacement tool includes a fixed seat 21, a wrench 22, a hexagonal block 23, a pin shaft 24, an upper cover plate 26, a cylindrical pin 27, a push-pull rod 30, a sealing plate 31, Nut 32, push plate 33, and aluminum cutter 34;

[0037] The fixed seat 21 is a square box-shaped part, and the side is equipped with an oil cylinder one 25 for dismounting the lock nut 16. The oil cylinder one 25 is connected to the wrench 22 through the pin shaft 24 positioned at the end of the wrench, and the front end of the wrench 22 is connected to the wrench 22 through six square blocks 23. The lock nut 16 at the top of the cavity 10 is connected, and the lock nut 16 is loosened and locked through the reciprocating movement of the oil cylinder 125;

[0038] The bottom surface of the fixed seat 21 is installed with an oil cylinder two 28 for ejecting the mould, and the upper cover plate 26 is connected ...

Embodiment 2

[0046] Utilize the tool described in embodiment 1 to carry out the replacement method of a kind of cable aluminum sheath continuous coating mould, as Figure 11 shown, including the following steps:

[0047] 1) Pack up the pistons of oil cylinder one 25 and oil cylinder two 28, install the push-pull rod 30 on the piston of oil cylinder two 28, and set the push plate 33 on the push-pull rod 30;

[0048] 2) Put the hot mold cavity 10 with a temperature of 400-500°C into the fixed seat 21, put one end of the hexagonal block 23 into the hexagonal hole of the lock nut 16, and put the wrench 22 into it so that one end is aligned with the hexagonal block 23 connection, the other end is connected with the piston of oil cylinder 25; extend the piston of oil cylinder 25, push the wrench 22 counterclockwise, the pressure of the oil cylinder is 20 MPa, and repeatedly loosen the lock nut 16 until it can be rotated manually until it is disengaged;

[0049] 3) Screw the hole sealing plate 3...

Embodiment 3

[0054] The steps of the replacement method for the continuous coating mold of a cable aluminum sheath described in this embodiment are the same as those in Embodiment 2, the difference is that the pressure of the oil cylinder 1 in the step 2) is 18 MPa, and the step 3 ), the pressure of oil cylinder 2 in step 4) is 12 MPa, the pressure of oil cylinder 2 in step 5) is 11 MPa, and the pressure of oil cylinder 1 in step 6) is 18 MPa.

Abstract

The invention provides a method and tool for replacing a continuous cladding mold for aluminum sheaths of cables, and belongs to the field of equipment manufacturing and cable manufacturing. A first oil cylinder used for dismounting a locking nut is mounted on the side face of a fixing base and is connected with a spanner through hinge pins located at the tail end of the spanner. The front end ofthe spanner is connected with the locking nut at the top end of a mold cavity through a hexagonal block. The first oil cylinder reciprocates to loosen or lock the locking nut. A second oil cylinder used for ejecting the mold is mounted on the bottom surface of the fixing base. A push-pull rod is connected with a piston of the second oil cylinder. When one end of the push-pull rod is connected witha hole sealing plate, the push-pull rod is used for removing a female mold body. When one end of the push-pull rod is connected with an aluminum cutter, the push-pull rod is used for cutting off residual aluminum. When one end of the push-pull rod is connected with a push plate, the push-pull rod is used for pushing out a male mold body. According to the method and device for replacing the continuous cladding mold for the aluminum sheaths of the cables, all components are ingenious in structure and design, a distribution mold does not need to be removed, soaking in a sodium hydroxide solutionis not needed, replacement of the male cladding mold body and the female cladding mold body can be completed in a short time (one hour), the mold replacement time is greatly shortened, the labor intensity is relieved, and meanwhile, the problem of pollution caused by waste sodium hydroxide liquor is solved.

Description

technical field [0001] The invention belongs to the fields of equipment manufacturing and cable manufacturing, and in particular relates to a rapid replacement method and tool for continuous coating molds of aluminum sheaths of cables. Background technique [0002] The continuous coating process is a new technology for the production of cable aluminum sheath, in which the assembly relationship of the aluminum sheath coating cavity (10) is as follows: Figure 1-Figure 2 As shown, it includes a cavity (11), a splitter mold (12), a punch (13), a die (14), a die set (15) and a lock nut (16). After one extrusion, the aluminum billet (17) will stay in the mold cavity, and the splitter mold (12), punch (13), concave mold (14), and mold sleeve (15) will be glued together to form an overall combination body (18); if the specifications need to be replaced, that is, when replacing the punch (13) and die (14), the lock nut (16) needs to be opened first, and then the splitter die (12), p...
