Novel seamless steel pipe blank pushing machine

Abstract

The invention provides a novel seamless steel pipe blank pushing machine. The novel seamless steel pipe blank pushing machine comprises a support and a workbench arranged on the support. The workbenchis provided with a square cavity. A base which is parallel to the workbench is arranged on the portion, at the bottom of the workbench, of the support. An adjusting device penetrating through the square cavity is arranged on the base and comprises a lifting mechanism and an adjusting mechanism which are arranged on the base. The lifting mechanism is provided with a cushion plate. The cushion plate is connected with a guide roller through the adjusting mechanism. Extension plates are arranged on the two sides of the cushion plate. Sliding rods rotationally connected with the extension plates are arranged at the positions, between the two extension plates, of the bottoms of the extension plates. The two sliding rods are connected through a frame. A sizing device is arranged on the frame. According to the novel seamless steel pipe blank pushing machine, the secondary perforation material pushing demand is met, the feeding stability and feeding efficiency are ensured, meanwhile, pushing of different pipe diameters is achieved, the adjusting precision is high, rapidness and convenience are achieved, the perforation precision is ensured, and the application range is wide.

Description

technical field [0001] The invention belongs to the field of seamless steel pipe production equipment, in particular to a novel seamless steel pipe pusher. 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 situation, the present invention proposes a new type of seam...
