Abstract
The utility model disclose a clamping device for round-section pipe materials, which is characterized in that a fixed frame (1) and a slideway disk (2) are concentric and relatively fixed; 3 to 7 radial direction slideways are evenly distributed on the axial end face of the slideway disk (2); a clamping slide block (3) which slides along the slideway is mounted on each slideway; a saw-tooth jack catches are formed at the inner ends of the clamping slide blocks (3); a roller (4) is arranged at the outer end of each clamping slide block (3); and an inner cam disk (5) which can rotate around the center of the fixed frame (1) is further arranged thereon. The clamping device drives the 3 to 7 jack catches to clamp a steel pipe by an inner cam, thereby dispensing with a complex multi-rod mechanism, increasing jack catches, and achieving the purposes that the structure of the clamping device is simple, and the clamping concentricity is reliable; the clamping strength is high and the clamped steel pipe can not deform.
Description
Technical field
The utility model relates to a kind of circular cross-section tubing gripping mechanism, particularly relates to a kind of clamping body that is used for fixing tubing when the tubing of slitting mill incising circular cross section.
Background technology
At present, on high-frequency straight welded pipe production line, adopt slitting mill cutting scale tubing more and more.Must be fixing when the slitting mill incising pipes to the tubing chucking, require captured tubing center pivot necessary and slitting mill coaxial simultaneously.Present widely used gripping mechanism all is to promote multi-bar linkage by hydraulic cylinder, make two claws from about or the mode of subtend chucking tubing up and down.Be called " novel steel tube gripping mechanism " as the disclosed name of Chinese patent CN2808438Y.In actual production, off-centre easily takes place with such chucking mode, cause the phenomenon that can't cut steel pipe (otch local adhesion and do not disconnect) to take place, roll blade also damages easily simultaneously.In addition, owing to be two claw chucking steel pipes, when increasing clamping force, steel pipe is gone out waste product by the card distortion easily.
Summary of the invention
In order to overcome the prior art above shortcomings, the utility model provides a kind of circular cross-section tubing gripping mechanism, and it is to promote the device that 3-7 claw tightens steel pipe simultaneously by a rotatable cam ring.This apparatus structure is simple, concentric reliably, clamping force is big and steel pipe can be by the card distortion.
The technical scheme that realizes above-mentioned purpose is: described circular cross-section tubing gripping mechanism has a fixed frame and fixedly mounts its sliding way disk with one heart, the individual radially slideway of uniform 3-7 on the axial end of slideway disk, installing one on each slideway can be along the chucking slide block of this slideway slip, the inner of chucking slide block is processed with the sawtooth claw and is used to tighten steel pipe, and its outer end is provided with a roller.Installing one on fixed frame simultaneously can be around the cam ring disk of its center rotation, the identical cam curved surface of the uniform 3-7 section of the radially inner side of this cam ring disk.Every section cam curved surface all is to be connected to form by involute surface and arc surface slyness, and each section cam curved surface joins end to end on same circumference, forms the convex wheel face of a sealing.The chucking slide block is close on the cam ring curved surface roller by spring reset.Fix a hinge in the outside of cam ring disk, link to each other with hydraulic cylinder by hinge, the hydraulic cylinder action can make the cam ring disk rotate.When the piston rod of hydraulic cylinder stretches out, promote the cam ring disk and rotate counterclockwise, the cam ring curved surface compressing roller on it make chucking slide block compression spring and along the slideway on the slideway disk to central motion, make 3-7 claw that tightens on the slide block tighten steel pipe simultaneously.When the piston rod of hydraulic cylinder was withdrawn, pulling cam ring disk clockwise rotated, and was resetted by spring promotion chucking slide block and unclamped steel pipe, and having finished once, chucking circulates.
The beneficial effects of the utility model are: because of design can promote 3-7 claw chucking steel pipe simultaneously by a cam ring, saved complicated multi-bar linkage and increased claw.Realized that gripping mechanism is simple in structure, chucking is reliable with one heart, clamping force is big and steel pipe can be by the purpose of card distortion.
