Description

Technical Field

[0001] The utility model relates to the technical field of parallel cluster production, and more specifically, to an overhead parallel cluster extrusion die. Background Art

[0002] Parallel cluster overhead insulated cables (abbreviation: parallel cluster conductors) are products promoted and applied in the "10th Five-Year" science and technology plan for the construction of rural power grids by the State Power Corporation. The reactance of low-voltage power supply lines consists of impedance, capacitive reactance, and inductive reactance. Parallel cluster conductors use three-phase four-wire power supply, which reduces the unbalance degree of the three-phase load of the distribution transformer to a minimum, reduces the neutral line current, and thus reduces the resistance loss. During the production process of overhead parallel cluster conductors, an extrusion type self-aligning die is often required.

[0003] The prior art discloses a new type of overhead parallel cluster extrusion die with the publication number: CN218749208U, which includes a die core and a die sleeve fixed on the die core. There is a cavity between the die core and the die sleeve. A plurality of bearing pipes are embedded and installed in the middle of the die core. The bearing pipes are in a bushing structure. One end of the bearing pipe is inserted into the cavity. The inner hole of the bearing pipe is divided into two sections, namely an inlet hole and an outlet hole. The inlet hole and the outlet hole are axially connected. The aperture of the inlet hole is larger than that of the outlet hole. The die sleeve is provided with sizing holes corresponding to the outlet holes one by one. This utility model designs a bearing pipe structure to reduce the abrasion of the conductor entering the bearing pipe; the outer diameter of the bearing pipe is the same as the aperture of the sizing hole, so that the deviation of the conductor from the center position of the sizing hole can be limited within the smallest range; when the extrusion plastic enters the cavity, due to the blocking of the bearing pipe in the cavity, the influence of the extrusion pressure on the conductor during production can be reduced, and the thickness of the extrusion material can be made uniform.

[0004] Before the above-mentioned utility model is used, the die core and the die sleeve need to be aligned and fixedly connected. The specific operation is to first align the first positioning hole and the second positioning hole and insert a positioning pin, and then align the outer edge fixedly installed on the edge of the die core and the threaded hole correspondingly opened on the die sleeve, and then screw a hexagon bolt into the threaded hole for fixation. This alignment and installation connection operation step is not only relatively complex, but also requires external tools, thus reducing the installation and use efficiency of this extrusion die, and its practicability is general.
