A dual-purpose machine for straightening and arc adjustment of multiple steel bars on site

Abstract

The invention belongs to the technical field of reinforcing steel bar machining devices and provides a on-site multi-reinforcing steel bar back straightening and arc adjusting dual purpose machine aiming at solving the problems that an existing special reinforcing steel bar back straightening machine can only straighten one reinforcing steel bar one time, the efficiency is low, the arc adjusting is conducted manually, the error is large, the adoption of a special bending machine is high in price, and the cost is increased. The on-site multi-reinforcing steel bar back straightening and arc adjusting dual purpose machine comprises a rack, a power mechanism and a reinforcing steel bar back straightening and arc adjusting mechanism, wherein according to the reinforcing steel bar back straightening and arc adjusting mechanism, a plurality of mutually paralleled transferring rollers are rotationally installed in the horizontal direction of the rack, a plurality of mutually paralleled multi-section groove solid core rolling cylinders are installed in the vertical direction of the rack, and the multi-section groove solid core rolling cylinders slide left and right relative to the rack and can be fixed. Meanwhile, multiple reinforcing steel bars are machined in a batch mode, the production efficiency is improved, the angle of machined reinforcing steel bars are easy to control, and the machining precision is high. The cost is saved. The on-site multi-reinforcing steel bar back straightening and arc adjusting dual purpose machine has the advantages that the mechanical power is low, the machining efficiency is high, the machining quality can be guaranteed, and the economical and practical effects are achieved.

Description

technical field [0001] The invention belongs to the technical field of mechanical processing devices for steel bars, and in particular relates to a dual-purpose machine for straightening and arc adjustment of multiple steel bars on site. Background technique [0002] At present, steel bars have been widely used in the civil engineering industry. When reinforcing some curved concrete structures, such as the second lining of tunnels, the four corners of circular foundation pits, etc., in order to meet the mechanical requirements, it is necessary to process steel bars with a certain curvature. The precision directly affects the quality of the concrete structure, which may cause adverse phenomena such as intrusion, insufficient protective layer, and uneven force. [0003] Before making arc-shaped steel bars on site, the disc-shaped steel bars produced by the steel factory must be straightened. The general method is to place the steel bars in the mold and straighten them by manua...

AI Technical Summary

Problems solved by technology

[0004] In order to solve the problem that the existing special steel bar straightening machine can only straighten one steel bar at a time, the efficiency is low, the arc adjustment after straightening may need to be done manually, and the error is large, and the special bending machine is expensive, which increases the production cost and maintenance To solve the problem of cost, a dual-purpose machine for returning, straightening and arc-adjusting multiple steel bars on site is provided.
