Automatic reducing system mechanism of rolling welder

Abstract

The invention discloses an automatic reducing system mechanism of a roller welder. The automatic reducing system mechanism of the roller welder comprises a face plate mechanism capable of rotating. The face plate mechanism comprises a face plate inner ring, a face plate outer ring, fixed wed plates and swinging web plates. Multiple annular sliding grooves are evenly and circumferentially distributed in the inner side of the face plate outer ring. The swinging wed plates can annularly slide along the annular sliding grooves and be fixed. Each fixed web plate and each swinging web plate are both provided with a welding seat and a web plate transmission mechanism controlled by an industrial personal computer. By the adoption of the structure, the welding seats can automatically move for a corresponding distance in the radial direction along the wed plates under the action of the web plate transmission mechanisms, and therefore various reinforcement cage cross-sectional shapes and reducing quantities can be accurately and rapidly formed; when reinforcement cages with cross sections provided with edges and corners are welded, the swinging web plates can be fine adjusted along the annular sliding grooves, and then it can be guaranteed that each corner of the cross sections, provided with the edges and corners, of the reinforcement cages is provided with a longitudinal rib; in this way, the automatic reducing system mechanism is high in flexibility.

Description

technical field [0001] The invention relates to a welding production equipment for a steel bar skeleton in the cement product machinery industry, in particular to an automatic diameter-changing system mechanism of a seam welding machine. Background technique [0002] At present, most of the steel frame seam welding machines used in domestic factories are mainly manual diameter changers. For the seam welding machine with manual variable diameter, when it is necessary to weld steel skeletons of different diameters, it is necessary to manually adjust the radial position of the welding seat of the longitudinal reinforcement on the faceplate. That is to say: when adjusting, you must loosen the clamping screws on each longitudinal rib welding seat, then move the longitudinal rib welding seat to the required radial position, and then tighten the screws after moving the position. [0003] The above-mentioned manual diameter reduction operation requires complex calculations in advan...

Problems solved by technology

[0003] The above-mentioned manual diameter reduction operation requires complex calculations in advance for different cross-sections of the steel skeleton during manual diameter reduction, and then needs to be equipped with a scale for on-site measurement. The work efficiency is low, the production cost is high, and it is difficult to adapt to the requirements of automated production. need
