1. Purpose

This machine is a special welding equipment for making reinforced concrete drainage pipe skeletons. It is suitable for welding sockets and flat-mouth reinforced skeletons. It is one of the main equipment for producing reinforced concrete drainage pipes.

2. Working principle

This machine is composed of four-way transmission system including main plate rotation, rib pushing plate pushing rib, variable diameter front and rear plate movement and welding mechanism movement, which are driven by their respective frequency conversion speed regulation systems. The electronic proportional speed control system controlled by PLC ensures that the pitch of the ring reinforcement and the angle of the socket do not change with the adjustment of the welding speed. Enter the corresponding parameters on the man-machine interface to change the pitch of the ring reinforcement and the angle of the socket. Correspondingly adjust the position of the welding station and welding mechanism on the main plate (electrically controlled), which can weld different specifications of drain pipe skeletons. It truly realizes the functions of one machine with multiple functions and man-machine dialogue.

This seam welding machine has dual-purpose flat mouth and socket socket, automatic continuous diameter reduction, synchronous speed regulation by all inverters, automatic close winding at both ends, arbitrary adjustable pitch of ring ribs, microcomputer control action, fully digital circuit control welding, convenient installation and debugging , It will be out of the network 2 hours after it is in place, and it only needs one person to operate it, which is 2-3 times that of the ordinary lacing seam welding machine. The welding wheel adopts special welding materials, and the service life is 5 times that of the ordinary welding wheel.
