A plastic shell of commutator Morgan mold is automatically pressed into the preheating mechanism

Abstract

The invention relates to the technical filed of automatic pressing of commutators, in particular to a plastic housing auto-pressing and preheating mechanism of Morgan molds of the commutators. The plastic housing auto-pressing and preheating mechanism is provided with a middle mold plate and is characterized by being composed of a transition plate, a transition plate moving assembly and a pressing and preheating assembly. The preheating mechanism is composed of the transition plate, the transition plate moving assembly and the pressing and preheating assembly, the transition plate moving assembly moves the transition plate to a transition plate supporting guide rail in the pressing and preheating assembly, then the pressing and preheating assembly presses plastic housings borne in the transition plate into a middle mold for heating the plastic housings, and a heating pipe carries out continuous heating in the conveying process so that the temperature of the middle mold plate can meet the pressing requirement. The plastic housing auto-pressing and preheating mechanism has the advantages that the operation is convenient, the working efficiency is high, the working performance is stable, the plastic housings can be automatically pressed into the middle mold and the middle mold can be automatically preheated.

Description

Technical field [0001] The invention relates to the technical field of automatic commutator pressing, in particular to a commutator Morgan which is convenient to operate, high in work efficiency, stable in performance, and capable of automatically pressing a plastic shell into a middle mold and automatically preheating the middle mold. The plastic shell of the mold is automatically pressed into the preheating mechanism. Background technique [0002] As we all know, the commutator is the original part of the DC permanent magnet series motor in order to keep the motor rotating. Structurally, the commutator is a circle with several contact pieces connected to each tap on the rotor. Connecting the two electrodes is called the brush contact, and only contacting two of them at the same time. The principle is that when the coil passes the current, it will be rotated by the attraction and repulsion force under the action of the permanent magnet. When balancing, the originally energized ...

Problems solved by technology

[0003] At present, in the commutator production line, before the commutator is pressed into shape, the copper bars need to be regularly put into the mold of the press. In order to facilitate the fixing of the copper bars, the copper bars are often inserted into special plastic molds. Among the shells, in the automatic press equipment, the automatic pressing of the plastic shell into the middle mold and preheating is an indispensable part. The current pressing of the plastic shell into the middle mold and heating is generally done manually, which is cumbersome and reduces work efficiency
