CNC flame plasma steel pipe slotting machine

Abstract

The invention relates to a numerical-control flame plasma steel tube grooving machine which comprises a ground positioning guide rail and a positioning travelling car arranged at the two ends of the ground positioning guide rail, wherein a forward and backward movement lifting device and a steel tube turnover frame are arranged on the positioning travelling car; the forward and backward movement lifting device is arranged at the rear end of the positioning travelling car; the steel tube turnover frame is arranged at the front end of the positioning travelling car; the forward and backward movement lifting device comprises a forward and backward moving device and a lifting device which is arranged on the forward and backward moving device; and a small numerical-control cutter is arranged at the top end of the lifting device. According to the numerical-control flame plasma steel tube grooving machine, a plurality of steel tubes can be arranged simultaneously by the steel tube turnover frame, and the plurality of steel tubes can be continuously grooved, and therefore, the grooving efficiency is high; moreover, the numerical-control cutter is used for cutting, so that the grooving quality is reliable; the forward and backward moving device controls the numerical-control cutter to move forwards and backwards, and the lifting device control the numerical-control cutter to move up and down, so that the ports of steel tubes with different tube diameters are grooved; besides, the steel tube positioning device is further arranged for counter-point aligning the end parts of the steel tubes, so that the grooving quality is improved.

Description

technical field [0001] The invention relates to a pipe fitting processing equipment, in particular to a steel pipe slotting machine for slotting pipe fittings. Background technique [0002] In the steel structure, the pipe structure is better than other structures because of its good structural stability. Most of the connections between the pipes are connected by flanges or insert plates. The insert plate connections are slotted on the ports of the pipe fittings. The grooving of the pipe fitting port generally adopts artificial flame grooving. This method has high technical requirements for the staff, and the efficiency is low and the quality is poor. In order to improve the quality of grooving, the current grooving of pipe fittings is gradually replaced by semi-automatic and numerical control. Although it can replace manual grooving, the investment is relatively large. Only one steel pipe can be grooved at a time, and it needs to be scanned first. The grooving efficiency I...
