Efficient cooling and shaping equipment for longitudinal welded pipe

Abstract

The invention discloses efficient cooling and shaping equipment for a longitudinal welded pipe. The efficient cooling and shaping equipment comprises a cooling water tank, supporting blocking rings are arranged at a feeding port and a discharging port of the cooling water tank, a water injection spray pipe is arranged on the upper portion of the cooling water tank, a water guide mechanism is fixedly arranged in the cooling water tank, and the water guide mechanism comprises branch bearing base frames and a driven roller; the number of the branch bearing base frames is two, the lower ends of the branch bearing base frames are fixedly connected with the bottom of the cooling water tank, a middle bearing base frame is arranged between the two branch bearing base frames, water distribution sleeves are rotatably arranged between the two sides of the middle bearing base frame and the two branch bearing base frames respectively, and a plurality of water permeable flow guide holes which are obliquely formed are formed in the water distribution sleeves; and the driven roller is rotationally arranged at the bottom of the cooling water tank. According to the efficient cooling and shaping equipment for the longitudinal welded pipe, the water permeable flow guide holes in the water diversion sleeves guide cooling water to enter the water distribution sleeves to flow and cool the welded pipe, so that the cooling water in the cooling water tank is quickly mixed, the cooling and shaping efficiency of the welded pipe is improved, and the cooling water waste caused by layered heating of the cooling water is reduced.

Description

technical field [0001] The invention relates to the technical field of production equipment for straight seam welded pipes, in particular to high-efficiency cooling and shaping equipment for straight seam welded pipes. Background technique [0002] Longitudinal welded pipe refers to the pipes obtained by welding the steel pipes made of hot-rolled or cold-rolled steel plates or steel strips on welding equipment for straight seam welding. According to different uses, it can be roughly divided into scaffolding pipes, fluid pipes, wire casings, bracket pipes, guardrail pipes, etc. Among them, in order to obtain square steel pipes, it is necessary to perform secondary processing on straight seam welded pipes. The generally used processing methods are: Round steel pipes are extruded through secondary molding equipment. [0003] The existing authorized patent announcement number is CN210172845U, which discloses a precision welded pipe production line, including feeding mechanism, ...

AI Technical Summary

Problems solved by technology

[0004] In the above technical solution, after the welding of the longitudinal welded pipe is completed, it needs to be cooled and shaped in the cooling water tank. The straight seam welded pipe inside keeps at high temperature, and the cooling water in the cooling water tank heats up accordingly, and this part of the heated cooling water is generally the upper layer, and the lower layer of cooling water will be discharged during the circulation process before the temperature rises in the future, causing the cooling water tank to heat up the high temperature welded pipe. The cooling and setting efficiency of the welded pipe is reduced, which affects the cooling and setting quality of the welded pipe, and causes a lot of cooling water waste
