Front swinging type strengthening rib thin wall spiral pipe welding machine

Abstract

The invention discloses a front swinging type strengthening rib thin wall spiral pipe welding machine, belongs to the field of spiral pipe welding machines and aims at achieving the technical purposeof providing the spiral pipe welding machine reasonable in structure, facilitating spiral angle adjustment through front axle swinging, high in installation precision, convenient to install and high in production efficiency. According to the technical scheme adopted for achieving the technical purpose, the front swinging type strengthening rib thin wall spiral pipe welding machine comprises a front axle, a forming machine and a rear axle. One end of the rear axle is fixed to the bottom of the forming machine, one end of the front axle is hinged to the bottom of the forming machine, and the front axle is sequentially provided with an uncoiling machine, a leveler, a shearing butt welding machine, rib pressing machines and a guide plate device in the direction of the forming machine, and thehinged position of the front axle and the forming machine is provided with a rotation shaft. A plurality of concentric circular sliding rails are arranged below the front axle, and sliding wheels arearranged between the front axle and the sliding rails, the front axle can rotate on the sliding rails through the sliding wheels, and accordingly the angle between the front axle and the forming machine is adjusted. The front swinging type strengthening rib thin wall spiral pipe welding machine can be widely applied to the field of the spiral pipe welding machines.

Description

technical field [0001] The invention relates to a front-swing thin-walled spiral welded pipe machine with reinforced ribs, belonging to the technical field of spiral welded pipe machines. Background technique [0002] Spiral welded pipes are mostly used in urban underground water supply and drainage pipeline networks, coal mine underground water supply and drainage, coal mine underground spraying pipe network, coal mine underground positive and negative pressure ventilation pipes, coal mine underground gas drainage pipes, etc. The existing spiral welded pipe machines are mostly It is a rear-swing type unit, and the uncoiler, leveler, and guide plate are installed on the ground foundation. Since the shapes of each unit are different, the construction of the cement foundation is complicated, and the relative installation accuracy between the units is low. Adjust the helix angle When the screw forming machine needs to swing with the rear axle at the same time, it is very inconv...
