Movable hydraulic automatic reinforcement cage main reinforcement clamping device

Abstract

The invention discloses a movable hydraulic automatic reinforcement cage main reinforcement clamping device and relates to the field of reinforcement cage automatic production equipment. The problemsthat existing reinforcement cage seam welder main reinforcement clamping devices are insufficient in clamping force, high in workload and low in efficiency are solved. The movable hydraulic automaticreinforcement cage main reinforcement clamping device comprises a clamping body, a hydraulic cylinder of which the outer side of the upper end is fixedly connected with the outer side of the lower endof the clamping body, a pretightening rod which is arranged in the clamping body and fixedly connected with a piston rod of the hydraulic cylinder, a rotation brake screw inserted into the clamping body and fixed to the side face of the upper end of the pretightening rod, a right-angle oil circuit block fixed to the side face of the outer portion of the clamping body, a rotary shaft which extendsinto the right-angle oil circuit block and is fixedly connected with the right-angle oil circuit block, and a hydraulic oil pipeline of which the upper end extends into the right-angle oil circuit block and the rotary shaft, wherein the upper end of the pretightening rod makes contact with a reinforcement cage main reinforcement; the hydraulic cylinder drives the pretightening rod through the piston rod so that the reinforcement cage main reinforcement can be clamped in the clamping body; a hydraulic oil pump is connected with the upper end of the hydraulic oil pipeline; and the lower end ofthe hydraulic oil pipeline communicates with the interior of the hydraulic cylinder through a valve. The movable hydraulic automatic reinforcement cage main reinforcement clamping device is large in clamping force, low in workload and high in efficiency.

Description

technical field [0001] The invention relates to the technical field of steel cage automatic production equipment, in particular to a movable hydraulic automatic steel cage main bar clamping device. Background technique [0002] In the process of steel cage production, it is first necessary to fix the main bars of the steel cage on the rotating disk 3 of the fixed disk system A of the polygonal steel cage roll welding machine. In order to realize the clamping of the main bars of the steel cage, the Chinese patent publication number CN104624874A disclose A "longitudinal bar locker at the end of the steel frame machine", which mainly uses the bolt tightening method to realize the clamping of the main reinforcement of the steel cage. This method requires manual use of a wrench, which is not only labor-intensive but also consumes a lot of working time. It directly leads to a decline in the production rate of the reinforcement cage. In addition, due to the continuous rotation of t...
