Automatic punching equipment for seamless steel tube

Abstract

The invention belongs to the technical field of automatic equipment, and particularly relates to automatic punching equipment for a seamless steel tube. The automatic punching equipment comprises a machine frame; an oil cylinder is fixedly connected to the top of the machine frame through a vertical rod; a punch is fixedly connected to the bottom of a piston rod of the oil cylinder; a sliding groove is formed in the position, corresponding to the oil cylinder, of the top of the machine frame; a fixing ring is fixedly connected to the top of a sliding block which is connected in the sliding groove in a sliding mode; a support plate is fixedly connected to one side of the fixing ring; a lead screw is connected to the position, corresponding to the support plate, of the machine frame in a rotating mode and is driven by a servo motor to rotate; the lead screw is connected to the support plate through a ball screw nut pair; a supporting rod is fixedly connected to the position, on one sideof the sliding groove, of the machine frame through a support; and a supporting column is arranged at the position, corresponding to the punch, of the supporting rod. According to the automatic punching equipment, the supporting column is inserted into the steel tube to support the punching position of the steel tube, and then deformation of the steel tube in the punching process is reduced.

Description

technical field [0001] The invention belongs to the technical field of automation equipment, in particular to an automatic punching equipment for seamless steel pipes. Background technique [0002] The seamless steel pipe is made by perforating the whole round steel, and the steel pipe without weld seam on the surface is called seamless steel pipe. According to the production method, seamless steel pipes can be divided into hot-rolled seamless steel pipes, cold-rolled seamless steel pipes, cold-drawn seamless steel pipes, extruded seamless steel pipes, and pipe jacking. According to the cross-sectional shape, seamless steel tubes are divided into two types: round and special-shaped, and special-shaped tubes have various complex shapes such as square, oval, triangular, hexagonal, melon-shaped, star-shaped, and finned tubes. [0003] Seamless steel pipes can be used to manufacture a variety of equipment parts. During processing, it is often necessary to drill holes in the pip...

Problems solved by technology

[0006] In order to make up for the deficiencies of the existing technology, when punching seamless steel pipes in the prior art, the steel pipe is moved to a predetermined position through the positioning unit, and then the steel pipe is punched after the punch is pressed down, but the steel pipe is in the punch. It is easy to deform during the stamping process, which will affect the punching accuracy of steel pipes and the punching quality of steel pipes. The invention proposes an automatic punching equipment for seamless steel pipes.
