Abstract

Belonging to the field of cable production equipment, the invention discloses a conductor extrusion device, which comprises a pedestal. The pedestal is provided with at least two fixation rods parallel to each other, the fixation rods are provided with a fixation nut which is in fixed connection with the fixation rods, the fixation nut is equipped with a screw hole, the radial direction of the screw hole is parallel to the length direction of the fixation rods, the screw hole is internally provided with a screw rod, the screw rod and the screw hole are in threaded connection, one screw rod end close to the pedestal is provided with a press rod, the press rod and the screw rod are coaxial and are connected through a bearing, one press rod end far from the screw rod is provided with a pressure head, the pedestal is equipped with a through-hole, and the projection of the through-hole on the bottom surface of the pedestal covers the projection of the pressure head on the bottom surface of the pedestal. The conductor extrusion device provided by the invention has the characteristics of convenient operation, multiple specifications, and large applicable range, employs the spiral extrusion mode, is labor saving, is free of potential risk, and has no influence to the work environment during operation.

Description

technical field [0001] The invention relates to the field of cable production equipment, in particular to a conductor extruding device. Background technique [0002] When the factory produces high-voltage cables, it must conduct a slice test of the cable insulation to check whether the insulation cross-linking degree is qualified. The way to do this test is to cut a section of cable, about 5 cm long, withdraw the conductor, and then slice the insulator. The main difficulty lies in the withdrawal of the conductor, because there are three layers of insulating layer outside the conductor, the cross-linked layer is very thick, and it is wrapped on it in a hot state, and shrinks after cooling, making it very tightly wrapped on the conductor. It's hard to quit. The current method is to rely on the tester to knock it out with a hammer head, which is very time-consuming and laborious, and it is very easy to hurt the tester's hands. In addition, the test insulator obtained in this ...

The current method is to rely on the tester to knock it out with a hammer head, which is very time-consuming and laborious, and it is very easy to hurt the tester's hands. In addition, the test insulator obtained in this way has many places that have been smashed on the surface. The test slice In order to obtain slices that meet the test requirements, it is necessary to remove the damaged part, which further increases the workload.
