A combined diameter-reducing mechanism of a seam welding machine

Abstract

The invention provides a combined diameter-reducing mechanism of a seam welding machine, which includes a frame, a rotatable faceplate mechanism, and a rotary drive mechanism for driving the faceplate mechanism to rotate. The frame includes a support frame and a support frame; the faceplate mechanism includes a forming turntable assembly, the longitudinal rib tray assembly, and the tray axial translation drive mechanism that drives the longitudinal rib tray assembly to translate relative to the forming turntable assembly; the rotation drive mechanism is installed on the support frame and connected to the faceplate mechanism through the guide shaft. It can be seen from this that this combined variable diameter mechanism can process steel cages of longitudinal bars with different diameters and specifications by replacing the faceplates with different aperture specifications. The structure is simple and the operation is stable. The mechanism can be widely used in the field of steel cage production equipment.

Description

technical field [0001] The invention relates to a combined diameter reducing mechanism of a seam welding machine, which belongs to the production equipment of reinforced concrete pipe reinforcement skeleton. Background technique [0002] The seam welding machine for producing reinforced concrete pipe steel skeleton is a special large-scale equipment for making reinforced concrete pipes. The steel skeleton seam welding machine currently used can only process steel skeletons with circular cross-sections. With the development of urban and rural construction in our country, various The demand for reinforced concrete pipes with different cross-sectional shapes is increasing. The special-shaped pipe steel frame roll welding machine is the equipment for processing the steel skeleton of reinforced concrete pipes with different cross-sectional shapes, and its demand is also increasing. As the key component of the steel frame seam welding machine, the reducing mechanism is the key to ...

[0003] The patent number is 201510184002.5 An automatic diameter-reducing system mechanism patent for a seam welding machine proposes an automatic diameter-reducing mechanism for a special-shaped steel bar skeleton, but the structure of the mechanism is complicated, and 48 stepping motors are installed on the main faceplate, and each stepper The motor drives a welding seat to form different cross-sectional shapes by changing the position of each welding seat relative to the center of the main faceplate

In the process of steel skeleton processing, 48 stepper motors rotate with the main faceplate, resulting in the problem of wire winding. Theoretically, this problem of wire winding can be solved by precision slip rings, but due to the large number of wires, the reliability of the system will inevitably be low. High failure rate
