Description

Technical Field

[0001] The utility model relates to the technical field of casting processing, and more specifically to a casting riser cutting and grinding and polishing device. Background Art

[0002] Castings are metal shaped objects obtained by various casting methods, that is, the smelted liquid metal is poured into a pre-prepared mold by pouring, injection, suction or other casting methods, and then cooled and polished to obtain objects with a certain shape, size and performance.

[0003] Riser refers to the supplementary part added on the top or side of the casting to avoid defects in the casting. Function In the casting, the cavity of the riser is the cavity for storing liquid metal. It supplies metal when the casting is formed, and has the functions of preventing shrinkage, shrinkage, exhaust and slag collection. The main function of the riser is to compensate for shrinkage. The design function of the riser is different. The form, size and opening position of the riser are different.

[0004] At present, after the casting is cooled and formed, it is necessary to use cutting and grinding equipment to cut and grind the riser. For seamless square tubes, the riser cutting process is generally manually pushed toward the cutting equipment, and the riser is cut and ground by the cutting equipment. Since it is difficult to ensure that it moves in a straight line due to manual feeding, slight deviations during the cutting process will cause damage to the seamless square tube workpiece. In view of this, we propose a casting riser cutting and grinding equipment. Utility Model Content
