Description

A high-efficiency fully automatic motor casting production line

technical field

The invention relates to the field of motor casting production lines, in particular to an efficient and fully automatic motor casting production line.

Background technique

Casting is a method of pouring liquid metal into a casting cavity adapted to the shape of the part, and after it is cooled and solidified, a metal part blank with a certain shape, size and performance is obtained.

The casting production line of the motor generally includes: a wax forming area, a metal melting area, a pouring area, a grinding area and a polishing area, and the wax forming area, the metal melting area, the pouring area, the grinding area and the polishing area are arranged in sequence . First, in the wax forming area, the casting to be made is made into a model with wax, and the model is welded to the gate rod with the same material to make a module; dip the surface of the module with refractory paint, such as: water The mixture of glass or silica sol and fine sand, and then sprinkle refractory sand, dipping and sanding should be repeated several times to make the sand layer thick enough, after it is dry and solidified, heat the module to remove the wax from the gate Then, in the pouring area, the metal liquid is poured from the gate, and after condensation, it becomes a metal casting; this method has relatively high precision, and Compared with sand core casting, it is more environmentally friendly; but in actual use, there are still some shortcomings:

1. In the wax forming area, when the wax is made into a model, it is usually necessary to use steel or aluminum molds, which are usually heavy. Usually, multiple people, forklifts or driving are used to carry up and down multiple times, and the operation is very complicated. Inconvenient, and there are potential safety hazards; because the wax needs to be melted at high temperature, it can be injected into the mold, and then the mold is allowed to cool naturally, so that the wax can be formed, which not only increases the temperature of the processing workshop, but also deteriorates the working environment, and the natural cooling time Long, affecting subsequent operations.

2. After the metal is melted in the metal melting area, the staff usually use a long-handled spoon to transfer the molten metal to the pouring bucket, so that the staff needs to work in a high-temperature environment. In the hot summer, the staff is very easy to Heat stroke occurs; and the molten metal will splash during transfer, and the staff working on the sidelines have greater safety hazards.

3. During the grinding process, the grinding is usually done by the staff, the grinding efficiency is low, and the metal debris under the grinding process flies into the air, causing air pollution. Working in this environment for a long time will seriously affect the staff of good health.

In view of this, the applicant conducted in-depth research on the above-mentioned problems, and this case arose.
