Abstract
The utility model discloses a steel pipe rotary device used for the quenching equipment of steel pipes, mainly composed of a motor (3), a speed reducer (4), a driving shaft (5), a chain driving mechanism (6) and a plurality of supporting wheels (2). The two wheels of each group of the supporting wheels (2) are driving wheels, and the connecting surface of the wheels and a steel pipe (1) is an arc-shaped curved surface. The speed of the motor is reduced through the speed reducer (4), and the chain driving mechanism (6) is driven by a drive shaft (5) to drive the two wheels pf the supporting wheels (2) to rotate simultaneously. The steel pipe (1) is drive the rotate through the friction between the wheels and the steel pipe (1), the friction between the steel pipe and the supporting wheel is increased, and the shaft movement during the rotation of the steel pipe is avoided.
Description
The utility model relates to a kind of steel pipe swivel arrangement that is used for the steel pipe quenching apparatus.
At present, the steel pipe swivel arrangement in the domestic and international steel pipe quenching apparatus mainly can be divided into steel pipe active rotation and passive rotation two classes.The steel pipe active rotation can be divided into dual mode again.A kind of is by clamp clamps steel pipe head, drives steel pipe and rotates.Owing to easily cause pipe end to damage with clamp clamps red heat steel pipe head, need be after quenching again the steel pipe of scale crop can adopt this mode.Another kind is with after several places compress on the steel pipe, by the stressed drive steel pipe of pipe end active rotation.This mode steel pipe unbalance stress is easy to generate torsion.The passive rotation of steel pipe mainly is the frictional force that relies between steel pipe supporting-point roller and steel pipe, drives the steel pipe rotation by supporting-point roller.Steel pipe is supported on the array supporting-point roller, and every group of supporting-point roller comprises the wheel that two axis are staggeredly arranged in parallel, and one of them is a motion-work wheel, drives the steel pipe rotation; Another is a driven wheel, only plays a supportive role.Therefore frictional force is little, particularly skidding very easily occurs for little, the lightweight steel pipe of those diameters.In order to increase frictional force, cylinder is adopted on the surface that supporting-point roller contacts with steel pipe, though so frictional force has increased, causes steel pipe to move axially in rotation.
The purpose of this utility model provides and a kind ofly can increase frictional force, and the steel pipe swivel arrangement of the passive rotation of axially movable steel pipe in the time of preventing the steel pipe rotation again is to improve the quenching quality of steel pipe.
The purpose of this utility model is achieved in that
A kind of steel pipe swivel arrangement, mainly form by motor, speed reduction unit, transmission shaft, chain-drive mechanism and array supporting-point roller, every group of supporting-point roller comprises the wheel that two axis are staggeredly arranged in parallel, and two wheels of every group of supporting-point roller are motion-work wheel, and the surface that wheel contacts with steel pipe is an arched surface.
Motor is a stepless speed-regulating motor, by regulating motor speed, can carry out step-less adjustment to the rotating speed of supporting-point roller wheel, and the steel pipe of different size all can be worked under suitable easy rotating speed.
The advantage that the utility model is compared with prior art had is: the wheel that adopts two initiatively arched surfaces is as supporting-point roller, both increased the frictional force between steel pipe and the supporting-point roller, guaranteed the running of steel pipe average rate, moving axially when having avoided the steel pipe rotation again guarantees the homogeneity of quenching, improved the quenching quality of steel pipe, in addition, this device also has the working reliability height, advantage applied widely, to specification is diameter 50～200mm, and the steel pipe between wall thickness 4～20mm is all applicable.
Introduce embodiment of the present utility model below in conjunction with accompanying drawing.
Fig. 1 is the plan structure synoptic diagram of the utility model steel pipe swivel arrangement.
Fig. 2 is the A-A sectional view of Fig. 1.
As shown in Figure 1 and Figure 2, the utility model mainly is made up of motor 3, speed reduction unit 4, main shaft 5, chain-drive mechanism 6 and array supporting-point roller 2.Motor 3 is 0～50HZ stepless speed-regulating motor, drives transmission shaft 5 through speed reduction unit 4 and rotates between 0～200rpm.Every pair of supporting-point roller 2 comprises the wheel that two axis are staggeredly arranged in parallel.Gap 1=50mm between two wheel side planes, wheel diameter is 300mm, the surface that contacts with steel pipe 1 is an arched surface.Chain-drive mechanism 6 passes to two wheels of supporting-point roller 2 by being installed in transmission shaft 5 and 2 liang of wheels of every group of supporting-point roller sprocket wheel on the axle separately respectively simultaneously with the motion of main shaft 5, makes two wheels of every group of supporting-point roller 2 be motion-work wheel.
During work, the steel pipe e Foerderanlage is delivered to the steel pipe 1 of red heat state on this swivel arrangement, supporting by array supporting-point roller 2, starter motor 3, slow down through speed reduction unit 4, two wheels that driven supporting-point roller 2 by transmission shaft 5 drive sprocket transmission rigs 6 rotate simultaneously, frictional force drive steel pipe 1 smooth operation between two wheels by every group of supporting-point roller 2 and the steel pipe 1.Contact for point with steel pipe 1 because supporting-point roller 2 wheel surface are arched surface, thereby can not cause steel pipe 1 to move axially in rotation, the rotating speed of motor 3 can be adjusted at any time, so that require control steel pipe rotating speed according to the specification and the quenching technology of steel pipe 1.
Claims (3)
1. steel pipe swivel arrangement, mainly form by motor, speed reduction unit, transmission shaft, chain-drive mechanism and array supporting-point roller, every group of supporting-point roller comprises the wheel that two axis are staggeredly arranged in parallel, it is characterized in that: two wheels of every group of supporting-point roller (2) are motion-work wheel, and the surface that wheel contacts with steel pipe (1) is an arched surface.
