Basic structure and principle of CNC steel cage welding machine

The CNC steel cage welding machine can be described as a kind of high-tech equipment developed on the basis of ordinary steel processing machinery. Because of its high degree of automation, high welding efficiency, and stable welding, it has been developed and applied rapidly.  In view of the fact that most customers are not very familiar with the equipment of the CNC steel cage roll welding machine, the following article will briefly introduce the basic structure and working principle of the CNC steel cage roll welding machine

The CNC steel cage seam welding machine is composed of 4 parts: reducing mechanism, traction mechanism, driving mechanism and welding feed mechanism. Its working principle is mainly to realize the clamping and reducing of longitudinal ribs by the reducing mechanism, and complete the socket part.  Forming, the traction mechanism pulls the longitudinal ribs to move linearly along the axis, adjusts the number of winding turns of the ring ribs on the longitudinal ribs, the driving mechanism drives the main faceplate and the traction faceplate to rotate, completes the winding of the ring ribs on the longitudinal ribs, and welds the feed mechanism  Complete the welding between the ring reinforcement and the longitudinal reinforcement.
 1. Reducing mechanism
 The diameter reducing mechanism of the CNC steel cage seam welding machine is composed of the main disc and the diameter reducing device on the disc. The diameter reducing device adopts the driving mode of "stepping motor + screw nut" to realize the movement of the welding seat, through the stepping motor  Control the displacement of the nut welding seat to achieve a total of 48 sets of diameter reduction.  The longitudinal ribs are clamped on the spokes of the main faceplate, and the main faceplate realizes the rotation and diameter reduction of the longitudinal ribs.  The chain is welded to the outside of the main faceplate. The main drive motor transmits power to drive the hexagonal square steel to rotate. The main sprocket mounted on the hexagonal square steel engages with the chain on the outside of the main faceplate. The bracket is installed with a tug and a stop wheel to coordinate the main faceplate.  Rotate.
 2. Traction mechanism
 The traction mechanism is mainly composed of a traction disc and a traction trolley.  The traction disk is rotated to complete the longitudinal clamping. The traction disk is traction and driven by the main drive motor. The main drive motor drives the hexagonal square steel to rotate. The trolley is equipped with a synchronous sprocket.  The hexagonal square steel is driven by the external chain meshing transmission of the synchronizing sprocket to synchronize the traction disk to realize the rotation of the traction disk.  The traction motor drives the linear motion of the traction trolley on the linear guide, and the traction motor drives the walking shaft to rotate. The walking shaft and the traction trolley are linked by bearings to complete the linear motion of the traction trolley.
 3. Drive mechanism
 The main driving part of the CNC steel cage seam welding machine is to drive the faceplate drive.  The main transmission part includes the main drive motor, reducer, main sprocket, synchronous sprocket and hexagonal square steel, the main sprocket and the main faceplate chain meshing transmission, the synchronous sprocket and the traction disc sprocket meshing transmission, both sprockets are installed in  The hexagonal square steel ensures the synchronous rotation of the main faceplate and the traction faceplate.
 4. Welding feed mechanism
 The welding feed part of the CNC steel cage seam welding machine mainly includes a moving device, a welding device and a fixed bracket.  The moving device includes a moving bracket, a guide rail, a servo motor, a ball screw, etc. The rotation of the motor drives the moving bracket to move through the screw nut width.  The moving bracket will receive the reaction force from the welding position during the working process, which will cause the overturning and offset of the moving bracket, and at the same time cause damage to the ball screw. In order to prevent this from happening, a cover plate and a trolley are installed on the track.  An anti-deflection wheel is added at the bottom.
