Description

Technical Field

[0001] The utility model relates to the technical field of seamless steel pipe piercing processing, in particular to a front lifting and adjusting mechanism for an automatic seamless steel pipe piercing machine. Background Technique

[0002] A seamless steel pipe is a long steel bar with a hollow cross-section and no seams around. During the production process of seamless steel pipes, piercing processing is often required, so an automatic piercing machine needs to be used. In order to prevent the seamless steel pipe from rolling during the piercing operation and affecting the piercing quality, most automatic piercing machines are provided with some limiting and fixing structures for the seamless steel pipe.

[0003] Most of the existing fixed limiting structures on automatic piercing machines drive the clamping seat to slide by rotating the screw rod, so as to clamp and fix the seamless steel pipe by using the clamping seat. However, multiple holes often need to be made on the seamless steel pipe. Therefore, in the actual processing process, the staff needs to frequently rotate the screw rod to control the disassembly and assembly of the clamping seat for the seamless steel pipe, and the staff also needs to push the seamless steel pipe forward many times to adjust the piercing position. Since some seamless steel pipes are heavy, it is very troublesome and laborious for the staff to operate, which is not only inconvenient to use, but also the labor intensity of the staff is relatively high.

[0004] Therefore, we propose a front lifting and adjusting mechanism for an automatic seamless steel pipe piercing machine. Content of the Utility Model
