Abstract
The invention relates to a device for clamping a steel tube when bending push to the steel tube is performed, in particular to a hydraulic clamping head for a bending push machine. The hydraulic clamping head mainly solves the problem that the steel tube is not clamped firmly enough due to the fact that workers clamp the steel tube through bolts and nuts when the bending push to the steel tube is performed at present. The hydraulic clamping head comprises a frame, wherein a clamping arm is rotatably connected with the frame, a plurality of clamping claws are arranged on the clamping arm, a clamping arm inclined surface is fixed on the outer side of the clamping arm, a clamping wedge is arranged between the clamping arm inclined surface and the frame and installed on a piston rod of a clamping oil cylinder which is installed on the frame and provided with an oil feeding pipe and an oil discharging pipe. The hydraulic clamping head for the bending push machine has the advantages that the steel tube can be clamped with large clamping force when the bending push to the steel tube is performed so that the steel tube cannot loose easily; and the hydraulic clamping head for the bending push machine is low in labor strength, high in efficiency and capable of enabling processing quality of products to be ensured.
Description
Technical field:
The present invention 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 that shortcoming is that manpower holds, and is prone to looseningly, influence the crudy of product and labour intensity height.
Summary of the invention:
Technical problem to be solved by this invention provides and a kind ofly can steel pipe 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, and jig arm is rotatably connected with frame, and 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, supplies to be 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 makes hydraulic oil get into clamping cylinder from following oil pipe; Piston moves upward, and promotes the clamping wedge extruding and clamps the inclined-plane, makes the jig arm jaw that steel pipe is clamped; After pushing away curved operation completion, hydraulic oil gets into 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 can steel pipe be clamped with very big clamping force, and it is loosening that it is difficult for, and labour intensity is low, and efficient is high, and the crudy of product is guaranteed.
Description of drawings:
Accompanying drawing is a structural representation of the present invention, and 9 is steel pipes among the figure.
The specific embodiment:
With reference to accompanying drawing, it comprises frame 1, and 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, supplies to be connected with hydraulic system.
