Description

High-efficient full automatization motor casting production line

Technical Field

The invention relates to the field of motor casting production lines, in particular to a high-efficiency full-automatic motor casting production line.

Background

Casting is a method in which liquid metal is poured into a casting cavity adapted to the shape of a part, and after the liquid metal is cooled and solidified, a metal part blank having a certain shape, size and performance is obtained. Whereas the casting line of electric machines generally comprises: the wax material forming area, the metal melting area, the pouring area, the polishing area and the polishing area are sequentially arranged in the installation and production sequence. Firstly, in a wax material forming area, a casting to be made is made into a model by using wax materials, and the model is welded on a gate rod by using the same material to make a module; dipping fire-resistant coatings on the die set surfaces, such as: spraying refractory sand on the mixture of water glass or silica sol and fine sand, dipping slurry and spreading sand repeatedly for several times to make the sand layer thick enough, heating the mould after it is dried and solidified, removing wax from the sprue to form hollow shell, and roasting the hollow shell to obtain firm mould shell; then, in a pouring area, pouring metal liquid from a pouring gate, and condensing to obtain a metal casting; the method has relatively high precision and is more environment-friendly compared with sand core casting; however, in practical use, there are some disadvantages:

1. in the wax material forming area, when the wax material is made into a model, a steel or aluminum mould is usually adopted, the weight of the mould is usually large, multiple persons, forklifts or traveling cranes are generally adopted for carrying the mould up and down for multiple times, the operation is inconvenient, and potential safety hazards exist; the wax material can be injected into the mould after being melted at high temperature, and then the mould is naturally cooled, so that the wax material is formed, the temperature of a processing workshop is increased, the working environment is deteriorated, the natural cooling time is long, and the subsequent operation is influenced.

2. After the metal is melted in the metal melting area, a worker usually transfers molten metal into a pouring ladle by using a long-handle ladle, so that the worker needs to work in a high-temperature environment, and the worker is very easy to have a heatstroke condition in hot summer; and the metal liquid can also splash when in transit, and workers working aside have great potential safety hazards.

3. In the polishing process, the polishing is usually carried out by workers, the polishing efficiency is low, metal fragments ground in the polishing process fly to the air, the air is polluted, and the health of the workers is seriously influenced by long-term work in the environment.

In view of the above, the applicant has made an intensive study to solve the above problems and has made the present invention.
