Punched high-frequency welded pipe unit

Abstract

The invention belongs to equipment for manufacturing perforated steel pipes and particularly relates to a punched high-frequency welded pipe unit, which comprises a punching machine and is characterized in that: a punched high-frequency welded pipe production unit which consists of a decoiling machine, a stepping feeding device, a punching device, a molding machine, a high-frequency welding device and a sizing device is arranged according to a continuous punched high-frequency welded pipe production process; a band plate to be processed which is supported on the decoiling machine is fed into the punching device through the stepping feeding device for punching; the punched band plate is driven into a pipe blank molding machine which consists of a base, a plurality of vertical roll frames and a plurality of horizontal roll frames; the high-frequency welding device which consists of a water cooling box, an electric control box and a high-frequency coil is arranged behind the pipe blank molding machine; and a welded pipe which is welded at a high frequency enters the sizing device. The punched high-frequency welded pipe unit has the advantages of reasonable design, compact structure, realization of mechanization, high production efficiency, good product quality, low labor intensity, safety of operation, convenience of use and the like.

Description

technical field [0001] The invention belongs to equipment for manufacturing steel pipes with holes, in particular to a punching high-frequency welded pipe unit. Background technique [0002] At present, in the manufacture of welded steel pipes with holes, it is widely used to make steel pipes first, and then use a punching machine to punch holes in the pipe fittings in another processing place. It has the following shortcomings and deficiencies: [0003] 1. It is difficult to punch holes on the round pipe, and it is difficult to position and replace the punching die [0004] 2. The labor intensity is high, because it is an off-line production at another processing location, which increases production equipment and labor costs [0005] 3. Only a single tube can be processed and punched, and the production efficiency is low Contents of the invention [0006] The purpose of the present invention is to avoid the shortcomings and deficiencies in the above-mentioned technolog...
