Description

Technical Field

[0001] This utility model relates to the technical field of high-frequency welded pipe units, specifically a traction-displacement type high-frequency welded pipe unit. Background Technology

[0002] The traction-shifting high-frequency welded pipe unit is a device used for short-distance shifting operations. Through the combination design of traction cable and buckle clamp, the device can achieve rapid short-distance shifting and is suitable for position adjustment scenarios in high-frequency welded pipe production.

[0003] To suit short-distance relocation operations and offer strong applicability and practicality, a traction-type high-frequency welded pipe unit (see patent number: 201821355088.9) has been developed. It includes a base, a unit body mounted on the base, two parallel guide holes within the base, and support seats symmetrically positioned at both ends of the guide holes. A guide steel column is fixed between the support seats, and a circular through hole is provided on each support seat. A locking screw communicating with the circular through hole is located on the top of each support seat, and a positioning screw communicating with the guide holes is located on the side of the base. A traction drive motor is fixed to the top of one of the support seats, and a traction winding disc is fixed to the main shaft of the traction drive motor. A traction cable fixing ring is fixed to the center of the symmetrical side of the base, and a traction metal cable is mounted on the traction winding disc. A buckle is fixed to the end of the traction metal cable. This utility model has a reasonable structural design, is convenient to operate, and is stable and reliable in use.

[0004] However, the misalignment of the die center in the existing traction-shifting high-frequency welded pipe mill can easily cause the billet to deviate from the center line during rolling, resulting in deviation. Furthermore, when the deformation angle is greater than 90°, the offset direction of the upper and lower roller die centers is different. When the deformation angle is less than 90°, the offset direction is opposite to that when it is greater than 90°, which results in poor billet operation and reduced utilization. Utility Model Content

[0005] The purpose of this utility model is to provide a traction-displacement type high-frequency welded pipe unit to solve the problem that misalignment of the die center can easily cause the billet to deviate from the center line during the rolling process, resulting in deviation.

[0006] To achieve the above objectives, the present invention provides the following technical solution: a traction-shifting type high-frequency welded pipe unit, including a welded pipe unit operating platform, traction rollers are provided on both sides of the top of the welded pipe unit operating platform, a rotating shaft is provided at the middle position of the bottom of the traction rollers, an inner ring is provided at the bottom end of the outer side of the rotating shaft, and arc-shaped support members are provided at the four corners of the outer side of the inner ring.

[0007] The number of arc-shaped support members is eight, and four arc-shaped support members are grouped together. Two arc-shaped support members are provided with arc-shaped fixing members at their bottoms. Fixing blocks are provided on both sides of the outside of the arc-shaped support members. A toggle rod is threaded to one end of each pair of fixing blocks.

[0008] The outer end of the lever near the fixed block is evenly provided with multiple sets of external threads.

[0009] As a further embodiment of this utility model: the number of fixing blocks is eight, and four fixing blocks form a group. One end of each group of fixing blocks is provided with a threaded hole extending to the other end. The actuating rod is threadedly connected to one group of fixing blocks through the mutual cooperation of the external thread and the threaded hole.

[0010] As a further improvement of this utility model: each of the remaining set of fixed blocks is provided with a miniature bearing at one end near the actuating rod, and the actuating rod is rotatably connected to the remaining set of fixed blocks through the miniature bearing.

[0011] As a further improvement of this utility model, the bottom of each pair of arc-shaped support members is fixedly connected to the top of the welding pipe unit operating table through an arc-shaped fixing member.

[0012] As a further improvement of this utility model, multiple sets of rolling balls are tumbling embedded on the end faces of the arc-shaped support member adjacent to the inner ring.

[0013] As a further improvement of this utility model: an annular pressure groove is provided at the middle position of the outer side of the traction roller, and the cross-section of the pressure groove is arc-shaped. The welded pipe body is pressed on the adjacent side of the two sets of traction rollers.

[0014] Compared with the prior art, the beneficial effects of this utility model are:

[0015] 1. By rotating the actuating lever under the action of the miniature bearing and adjusting the distance between the arc-shaped support and the inner ring connected to the actuating lever by thread, the position of the rotating shaft at the center can be adjusted by adjusting the distance between the outer arc-shaped support and the inner ring. This allows for timely adjustment and tightening of the roll positioning and bearing locking status, thereby correcting misalignment of the die center and preventing the billet from deviating from the center line and causing deviation during rolling. This improves operational stability and increases utilization.

[0016] 2. By setting up arc-shaped fixing parts, the bottom of one set of arc-shaped support parts is fixedly connected to the top of the welding pipe unit operating table through the arc-shaped fixing parts, thereby providing a stable reference point for the rotating shaft and traction roller during adjustment, thus making subsequent left-right and forward-backward adjustments more stable.

[0024] Please see Figures 1-4In this embodiment of the utility model, a traction displacement type high-frequency welded pipe unit includes a welded pipe unit operating platform 1. Traction rollers 101 are provided on both sides of the top of the welded pipe unit operating platform 1. A rotating shaft 102 is provided at the middle position of the bottom of the traction rollers 101. An inner ring 2 is provided at the bottom end of the outer side of the rotating shaft 102. Arc-shaped support members 201 are provided at the four corners of the outer side of the inner ring 2.

[0025] There are eight arc-shaped support members 201, and four arc-shaped support members 201 form a group. Arc-shaped fixing members 202 are provided at the bottom of two arc-shaped support members 201, and fixing blocks 203 are provided on both sides of the outside of the arc-shaped support members 201. A toggle rod 204 is threaded to one end of each pair of fixing blocks 203.

[0026] Among them, the outer end of the toggle lever 204 near the fixed block 203 is evenly provided with multiple sets of external threads.

[0027] Please refer to this carefully. Figures 1 to 4 There are eight fixing blocks 203, and four fixing blocks 203 form a group. One end of each group of fixing blocks 203 is provided with a threaded hole extending to the other end. The actuating rod 204 is threadedly connected to one group of fixing blocks 203 through the mutual cooperation of the external thread and the threaded hole.

[0028] Please refer to this carefully. Figures 1 to 4 Each of the remaining set of fixed blocks 203 is provided with a miniature bearing 205 at one end near the actuating lever 204, and the actuating lever 204 is rotatably connected to the remaining set of fixed blocks 203 through the miniature bearing 205.

[0029] In this embodiment, the lever 204 is set long enough to allow for adjustment operations on the traction roller 101 from the side and below, without being obstructed by the outer diameter of the traction roller 101, thus facilitating operation.

[0030] Please refer to this carefully. Figures 1 to 4 The bottom of each pair of arc-shaped support members 201 is fixedly connected to the top of the welding pipe unit operating table 1 through arc-shaped fasteners 202.

[0031] Please refer to this carefully. Figures 1 to 4 Multiple sets of rolling balls are rolled and embedded on the end faces of the arc-shaped support member 201 and the inner ring 2.

[0032] Please refer to this carefully.
