Description

TECHNICAL FIELD

[0001] The present application relates to the field of rough machining of aluminum alloy die-casting products, in particular to a gantry type pressing and cutting mechanism suitable for motor water jackets. BACKGROUND

[0002] The motor water jacket is first die-cast into a cylindrical product blank from aluminum alloy material, and then rough machining and finishing are performed to become a finished product. In the process of die-casting, in order to ensure the complete and dense filling of the motor water jacket blank, and at the same time to discharge the aluminum liquid oxidation layer, a runner and a ladle are arranged respectively. After die-casting, these parts are formed together with the motor water jacket product. At this time, the die-casting product needs to enter the rough machining production line. The first process in the rough machining production line is to remove the runner and the ladle of the motor water jacket.

[0003] Due to the large volume of the runner and the ladle, it is not convenient to directly enter the equipment for machining. Usually, workers use a sledgehammer to knock them off. The on-site noise is loud, and the labor intensity of the workers is also very large. With the continuous improvement of social and personal awareness of workers' health, the demand for improvement of the working environment is becoming more and more urgent. In view of the above situation, some C-type body pressing and cutting and shearing equipment have appeared in the prior art. However, the cutting stroke of the C-type body pressing and cutting and shearing equipment can only be from top to bottom and cannot be adjusted. Therefore, it can only solve the simple and regular ladle. For some complex ladles, manual processing is still required.

[0004] Based on this, the present application aims to provide a gantry type pressing and cutting mechanism suitable for motor water jackets to solve the problem that only simple and regular ladles can be mechanically removed in the pressing and cutting process of the runner and the ladle of the motor water jacket.

The positioning tool is detachably installed on the base, and the pressing and cutting mechanism can be adapted to different specifications of motor water jacket products by replacing the positioning tool. The two pressing and cutting tool heads are in the shape of a semi-ring. After the two pressing and cutting tool heads are closed, they can be wrapped around the entire outer periphery of the motor water jacket.
