Clamping mechanism of rebar straightening device

Abstract

The invention discloses a clamping mechanism of a rebar straightening device. The clamping mechanism comprises a power cylinder, a drive rod, a left clamping block and a right clamping block. The drive rod is arranged in the direction perpendicular to the length direction of rebars, and a piston rod of the power cylinder is connected to the middle of the drive rod. The left clamping block and the right clamping block are connected to the left end and the right end of the drive rod respectively, the right side face of the left clamping block and the left side face of the right clamping block are opposite and both parallel to the length direction of the rebars, and a rebar clamping region is formed between the right side face of the left clamping block and the left side face of the right clamping block. A left side inclined guide block is arranged in the left side direction of the left clamping block, a right side inclined guide block is arranged in the right side direction of the right clamping block, the interval between the left side inclined guide block and the right side inclined guide block linearly increases or decreases in the length direction of the rebars, and the left clamping block and the right clamping block synchronously move along the left side inclined guide block and the right side inclined guide block respectively. The clamping mechanism can effectively clamp the rebars.

Description

technical field [0001] The invention relates to a clamping mechanism of a steel bar straightening device. Background technique [0002] The main reinforcement of the prefabricated high-strength concrete square pile reinforcement cage is made of HRB400 rebar, which is formed by automatic seam welding, saving time and effort, and the quality is easily guaranteed. In the seam welding production line of the steel cage, it generally needs to go through the process of butt welding-grinding-cutting-roll welding forming. Before carrying out the seam welding forming process, the steel bar needs to be straightened first to ensure that the steel bar can pass through the steel bar piercing of the seam welder smoothly. However, there is no special steel bar straightening device in the prior art. Based on this, the prior art needs further Improve. Contents of the invention [0003] The purpose of the present invention is to provide a clamping mechanism of a steel bar straightening dev...
