AI Technical Summary

Technical Problem

The existing perforated steel pipe production pole is threaded to connect to the head, which causes the head to wear easily when it is used for a long time, and the replacement process is cumbersome. The pole is easily shaken during the perforation process, resulting in uneven thickness of the tube blank.

Method used

Design a seamless steel pipe production machine top rod device, through top, fixed block, top rod body, card slot, limited tank, card, cavity, stretching spring, limited rod, support spring, support, support The combined structure of the rod and the connection box realizes the rapid disassembly of the top and the top rod, and the settings of different sizes are made through the stands of brackets, clipped blocks, thread rods, sliding rods, motors, two -way screws, threads, and support rollers to achieve different sizes. The limit of the blank is held.

Benefits of technology

The rapid disassembly of the top and the top rod is realized, reducing the tedious process of replacing the top of the top, and through the limit clamping technology to ensure the thickness of the tube billet.

Abstract

The utility model discloses an ejector rod device of a perforating machine for seamless steel tube production, which relates to the technical field of perforating machines for seamless steel tube production, and comprises a workbench, rollers, a tube blank, an ejector head and an ejector rod body, the rollers are arranged above the workbench, the tube blank is arranged between the two rollers, the ejector head is arranged inside the tube blank, and the ejector rod body is arranged on the workbench. The side, away from the pipe blank, of the ejector head is connected with a fixing block in a clamped mode. Through the arrangement of the ejector head, the fixing block, the ejector rod body, the clamping groove, the limiting groove, the clamping block, the cavity, the extension spring, the limiting rod, the containing cavity, the supporting spring, the supporting rod and the connecting frame, when the ejector head is seriously abraded, the ejector rod body can be screwed, the fixing block and the ejector rod body can be separated, and then the supporting rod is pulled; and the limiting rod is driven by the stretching force of the stretching spring to reset and move towards the middle, so that the limiting rod is separated from the limiting groove in the top head, and the purpose of conveniently and rapidly disassembling the top head, the fixing block and the top rod body is achieved.
