Horizontal inner hole wiring machine

Abstract

The horizontal inner hole wiring machine as one apparatus for wiring plastic connecting part includes frame, resistance wire heating machanism, drawing rotation mechanism and wire feeding mechanism. It features the drawing rotation mechanism with speed regulating motor and transmission box mounted on the frame, inner drawing roller, outer drawing roller and balance block; and the wire feeding mechanism with wire feeding speed regulating motor, electromagnetic clutch, cantilever support tube and steering gear. The resistance wire after being turned in the wire feeding gears moves along the inner wall of the plastic casing, the plastic casing is rotated by the inner and outer drawing rollers and resistance wire is pressed and embedded into the inner wall of the plastic casing to complet the production of electric smelting and connecting part.

Description

technical field [0001] The invention belongs to the technical field of plastic pipe products, in particular to a production equipment for inner hole wiring of plastic connectors. Background technique [0002] In the prior art, three steps are required to make the electrofusion pipe fittings: 1. Making the thin inner liner; 2. Cutting grooves from the outer surface of the thin inner liner and winding; 3. Re-injecting to make the electrofusion pipe fittings. This processing method is mainly to cut grooves and wires on the outer surface of the thin inner liner. In order to make the wire as close as possible to the inner surface, the depth of the groove must also be close to the inner surface, which will adversely affect the mechanical strength of the thin inner liner. Also increase work difficulty and workload. In addition, the Chinese patent also discloses a vertical plastic casing inner hole wiring machine. Due to the structural limitation, the processing diameter of this wi...
