Front lifting adjustment mechanism for seamless steel tube perforating machine

Abstract

The invention provides a front lifting adjustment mechanism for a seamless steel tube perforating machine. The front lifting adjustment mechanism comprises a square rod which is arranged on the side lower portion of a base plate and is in sliding connection. A plurality of idler wheels are evenly distributed on the square rod. Guide rollers on the corresponding base plate correspond to the idler wheels. The guide rollers are arranged on the base plate in a rotating connection mode through support plates. One side of each support plate extends out of the base plate, and the bottoms of the support plates are in rotating connection with rotating wheels matched with the idler wheels through fixing racks. Fixing rods are symmetrically arranged at one side of each support plate, and one pin shaft penetrates through the two fixing rods to be in rotating connection with the corresponding support plate. Cushion blocks are arranged at the bottoms of the support plates and located at the sides symmetrical with the pin shafts. The fixing racks are arranged at the ends far away from the pin shafts. According to the front lifting adjustment mechanism for the seamless steel tube perforating machine, the feeding heights of steel tubes can be accurately adjusted, height change can be achieved through stable structure matching, and therefore the guide rollers can be adjusted at different rotating angles, precision and stability are high and the service life is long.

Description

technical field [0001] The invention belongs to the field of seamless steel pipe production equipment, and in particular relates to a front lifting adjustment mechanism of a seamless steel pipe piercing machine. Background technique [0002] In the production and processing of seamless steel pipes, piercing steel pipe blanks is an indispensable link in the processing process. In the process of piercing, sometimes a good piercing state cannot be completed at one time, and secondary processing is often required. In the secondary processing, the billet becomes a steel pipe with holes. In this case, the diameter of the steel pipe changes, and the inside becomes hollow. The existing billet pusher has a simple structure and can only realize the straightening of the cylindrical billet. The advancement, and the scope of adaptation is small, does not meet the actual production needs, there is an urgent need for a special equipment that can meet the actual needs. In view of this situ...
