Abstract
The utility model relates to a cut following machine for the spiral welded steel pipe which is an improvement to the prior cut following machine for the spiral welded steel pipe, comprising a vehicle frame, a wheel combination, a pipe clamp, an adjustable lifting base, a cutting gun floater and a back stroke device. The utility model has the advantages of convenient operation, light weight, high quality, accurate motion and rapid operation and can satisfy the requirements of high-speed continuous production.
Description
The utility model is the improvement about spiral welding system steel pipe cutting retinue machine.
In the continuous flow procedure of spiral welding system steel pipe, the steel pipe that is welded into will cut off by certain size, and cuts out groove.Traditional cutting method is: (1) flies milling, and its circumference cut-off velocity generally is no more than 1.2 meters/minute; (2) flame-cutting, its cut-off velocity are generally below 0.7 meter/minute.These two kinds of cutting methods all can not satisfy the requirement of fly-cutting on the spiral welding system pipe production line, especially on ratio-frequency welding helix tube production line, send plate speed and go out pipe speed to reach 5 meters/minute and 3.5 meters/minute respectively, are about 2-3 times of submerged-arc welding helix tube.Present domestic tubulation producer adopts artificial armed follow-up gas cutting to cut off on ratio-frequency welding helix tube production line, this cutting method, and labor strength is big, easily burns, and kerf quality is not high, and yield rate is lower, and pipe end is still needed and is carried out secondary cut, and waste material is many.
Adopt the plasma cutting can reach the requirement of fly-cutting on the spiral welding system pipe production line, otch is bright and clean, and workpiece deformation is little, but must the corresponding cutting of configuration retinue machine.
Domestic tube mill used cutting retinue machine mostly is the tube gripper that flies the milling special use, tube gripper will bear the cutting force that flies to mill, tube gripper clamps by the frictional force between clamp and tube wall, clamp carries out work by air cylinder driven, the physical dimension of each force transmission mechanism is big, the effective rate of utilization of power only accounts for motive 10-15%, the cylinder piston diameter that drives the clamp arm is more than φ 250mm, adopt double-piston, thrust reaches more than 5000 kgfs, therefore tube gripper is bulky, and tube gripper is conducted oneself with dignity about 5000 kilograms.
Also have the special-purpose tube grippers of some gas cuttings, its clamping is still by the frictional force between claw and the steel pipe and realizes, but structure is still complicated, huge.
The purpose of this utility model is to provide a kind of economic, practical, light, reliable thermal cutting retinue machine for using on the spiral welding system pipe production line.
The alleged spiral welding system steel pipe cutting retinue machine of the utility model is by guide rail, vehicle frame, wheel combination, parts such as adjustable lifting pedestal, tube gripper, burning torch flotator, return device are formed, adjustable lifting pedestal, tube gripper, burning torch flotator, return device all are installed on the vehicle frame that channel-section steel is welded into, wheel combination links together by pedestal and the floating type assembling of vehicle frame, wheel support on guide rail, whole retinue machine back and forth movement on guide rail.
Characteristics of the present utility model are: the break bar of tube gripper and balance roller are by cylinder, hyperboloid cam, clamp arm, push rod, driving break bar and balance roller clamp the spiral steel pipe that is welded into, break bar is with its cutting edge wedging pipe outer wall, the balance roller is corresponding with break bar, as auxiliary wheel, balance roller wheel rim is flat blunt, does not wedge steel pipe walls.Adopt the both arms two-wheel to clamp like this and make the steel pipe stress equalization, the retinue machine is not increased multiple carrying.Because break bar wedging tube wall, with this wedging power, screw when making the retinue machine go out to manage with spiral steel pipe is a power, drives the retinue machine and goes out tube side to motion in the guide rail upper edge, after break bar and balance roller clamp steel pipe, can arcing cut, the steel pipe rotation, two-wheeled rolls along the pipe outer wall, and its rolling track is an enclosed planar circle, burning torch is contained on the swivel of burning torch flotator, and burning torch is about to steel pipe and cuts off on circumference.Thereby guarantee that by means of flotator burning torch cuts the distance of chewing end and steel tube surface and keeps constant, the burning torch flotator adopts bidirectional elastic to regulate, and universal wheel is equipped with in the flotator end, and universal wheel is along the tube wall surface automatic guide.For satisfying the cutting of various different-diameter steel pipes, tube gripper is contained on the adjustable lifting pedestal, so that regulate on short transverse.The break bar of tube gripper again can be relative to the vertical direction horizontal adjusting of the center line of Pipe Cutting on bearing separately with the balance roller, and is parallel with the steel pipe center line for guaranteeing the break bar axis of rotation, on the push rod of break bar worm gear is housed, so that levelling.The push rod afterbody of break bar and balance roller is equipped with spring, to regulate clamping force to steel pipe, in addition, when steel pipe when circle or weld flush position are by two-wheeled, by this spring from moving accommodation.The clamping force of tube gripper is leaned on the force amplificatory structure of cam and clamp arm that cylinder thrust is amplified and is obtained.
Cutting finishes, and the retinue machine drives reposition by the return device, circulates next time.
Use the alleged spiral welding system steel pipe cutting retinue machine operation of the utility model convenient, it is accurate, brisk to move, compact conformation, in light weight, maximum clamping force is 60kgf, dolly moves required tractive force less than 10kgf, bevel angle is 30 °-35 °, cut oblique deviation less than 1.5mm, return speed 8-10 rice/minute, complete machine weight is 225kgf, cylinder piston diameter 50mm, this retinue machine is suitable for thermal cutting at random on the production line of spiral welding system steel pipe, for all kinds of steel pipes of wall thickness 8-6mm, the line cutting speed can reach 3-3.8 rice/minute.
The utility model is realized with following technical proposals.
