A heating device for making cables

Abstract

The invention discloses a heating device for manufacturing a cable. The heating device comprises a box body, wherein an intermittent feeding groove is formed in the box body, a first sliding groove with a downward opening is formed in the top wall of the intermittent feeding groove, a second sliding groove with a backward opening is formed in the front end wall of the intermittent feeding groove,an intermittent feeding mechanism is arranged at the intermittent feeding groove, a crank sliding block mechanism is arranged on the rear side of a third sliding groove, a heating pipe is fixedly arranged on the right end wall of the intermittent feeding groove, a surrounding heater is fixedly arranged on the outer side of the heating pipe, the right end of the heating pipe is fixedly connected with a cooling cavity, a cooling mechanism is arranged in the cooling cavity, and the right wall of the bottom end of the cooling cavity is fixedly connected with an outlet pipe. According to the heating device, cable materials can be intermittently fed and heated, so that the heating is uniform and sufficient; and with the spiral cooling pipe, the contact surface is large during cooling, and the cable materials cannot be intertwined with one another, so that the cable materials can be quickly and sufficiently cooled to the subsequent required temperature.

Description

technical field [0001] The invention relates to the technical field of cables, in particular to a heating device for making cables. Background technique [0002] A rope-like cable usually made of several wires or groups of wires twisted together, each group of wires is insulated from each other, and is often twisted around a center, and the entire outside is covered with a highly insulating coating. The cable has the characteristics of internal electrification and external insulation. [0003] Cables often need to be heated during the production process. At this stage, the heating of cable materials is often not sufficient and uniform, which will bring disadvantages to subsequent operations. Moreover, the heated cable materials are often entangled and difficult to handle, and cannot be cooled quickly. The temperature required for subsequent operations is very inefficient and laborious. Contents of the invention [0004] In view of the deficiencies of the above-mentioned ...
