Abstract
The utility model relates to a device used for clamping a steel pipe during the push bending, in particular to a hydraulic chuck of a push bending machine in order to solve the problem that the steel pipe is clamped by a bolt and a nut manually during the push bending process of the steel pipe, and the clamping is not firm. The hydraulic chuck comprises a frame, a clamping arm is rotatably connected with the frame, a plurality of clamping jaws are arranged on the clamping arm, a clamping arm inclined plane is fixed at the outer side of the clamping arm, a clamping wedge is arranged between the clamping arm inclined plane and the frame, the clamping wedge is arranged on a piston rod of a clamping oil cylinder, the clamping oil cylinder is arranged on the frame, and an upper oil pipe and a lower oil pipe are arranged on the clamping oil cylinder. The hydraulic chuck of the push bending machine has the advantages that the steel pipe can be clamped by great clamping force during the push bending and does not easily loosen, the labor intensity is low, the efficiency is high, and the machining quality of the products can be guaranteed.
Description
Technical field:
The utility model relates to a kind of device that is used to clamp steel pipe when bending that steel pipe is pushed away.
Background technology:
Steel pipe being pushed away when curved, all be to take artificial method with screw bolt and nut steel pipe to be clamped at present, it is fastening inadequately, easily loosening that shortcoming is that manpower holds, and influences the crudy of product, and the labour intensity height.
Summary of the invention:
Technical problem to be solved in the utility model provides and a kind ofly steel pipe can be clamped when curved in that steel pipe is being pushed away, and it is loosening that it is difficult for, and labour intensity low push away the bender hydraulic chuck.
Above-mentioned purpose is achieved in that it comprises frame, jig arm is rotatably connected with frame, several jaws are arranged on the jig arm, the outside of jig arm is fixed with the jig arm inclined-plane, between jig arm inclined-plane and the frame clamping wedge is arranged, clamping wedge is contained on the piston rod of clamping cylinder, and clamping cylinder is contained on the frame, clamping cylinder has last oil pipe and following oil pipe, for being connected with hydraulic system.
Operation principle and advantage: will push away curved steel pipe during work and be fixed on the frame, the primer fluid pressing system, make hydraulic oil enter clamping cylinder from following oil pipe, piston moves upward, and promotes the clamping wedge extruding and clamps the inclined-plane, make the jig arm jaw that steel pipe is clamped, after pushing away curved operation and finishing, hydraulic oil enters clamping cylinder from last oil pipe, and piston moves downward, steel pipe is released, just can take off from frame.Advantage is that steel pipe is pushed away when bending and steel pipe can be clamped with very big clamping force, and it is loosening that it is difficult for, and labour intensity is low, and the efficient height can make the crudy of product be guaranteed.
Description of drawings:
Accompanying drawing is a structural representation of the present utility model, and 9 is steel pipes among the figure.
The specific embodiment:
With reference to accompanying drawing, it comprises frame 1, jig arm 2 is rotatably connected with frame, several jaws 3 are arranged on the jig arm, and the outside of jig arm is fixed with jig arm inclined-plane 4, and clamping wedge 5 is arranged between jig arm inclined-plane and the frame, clamping wedge is contained on the piston rod of clamping cylinder 6, clamping cylinder 6 is contained on the frame, and clamping cylinder has last oil pipe 7 and following oil pipe 8, for being connected with hydraulic system.
