Description

Production line for hub casting

Technical Field

The invention belongs to the technical field of hub casting, and relates to a hub casting production line.

Background

The hub of the electric vehicle is generally manufactured by an aluminum casting process, and is formed by pouring molten aluminum into a casting mold, and in order to improve the strength of the hub, a steel ring is embedded in the hub, such as a novel hub disclosed in chinese patent literature (application No. 201910936264.0).

At present, the casting process of the hub with the steel ring is mainly realized by manual operation, and the manufacturing process of the hub mainly comprises the steps of placing the steel ring, pouring molten aluminum and taking out the hub. 1. The steel ring and the steel core are required to be accurately placed at the designated position of the die when the steel ring is placed, the casting die is still high in temperature after the last wheel hub is taken out, a worker needs to place the steel ring through a clamp, the steel ring cannot be placed in place at one time when the steel ring is placed manually, and the position needs to be adjusted, so that the steel ring and the steel core are required to be placed for a long time, the production efficiency is low, the quality of the wheel hub is influenced due to the fact that the placing position is not in place; 2. when the aluminum water is poured, workers scoop the aluminum water out of the aluminum ingot melting furnace through the aluminum water scoop, and when the aluminum water is poured into the casting mold, the temperature of the aluminum water is extremely high, so that the working environment is in a high-temperature state, the aluminum water is extremely unfriendly to the workers, the aluminum water is extremely dangerous, the operation danger coefficient is high, the amount of the aluminum water cannot be controlled by further manually scooping the aluminum water, the problem that more or less aluminum water is generated in one-time operation is solved, the repeated operation is caused, and the production efficiency is reduced; 3. when the wheel hub is taken out, the casting mold needs to be cooled down firstly, workers need to wait in the cooling process, the wheel hub needs to be taken out by matching with a tool after the cooling is finished, and then the casting mold is washed, for example, an aluminum alloy wheel hub blank transfer system (application number 201210568777.9) disclosed by Chinese patent documents has low efficiency and is dangerous.
