Description

Technical Field

[0001] This utility model relates to the field of hot bending technology of steel pipes, and in particular to a rocker arm support adjustment device for a pipe bending machine. Background Technology

[0002] Pipe bending is frequently used in industries such as gas, electricity, and petrochemicals. However, the rocker arm of existing hot bending pipe bending machines has a limited stroke, which can only bend some conventional pipe models. For special pipe models, hot bending cannot be performed directly, and splicing and welding are the only methods to achieve this. This results in low pipe bending efficiency, poor product quality, and the splicing weld is prone to leakage after long-term use, which greatly reduces the service life of the pipe. Summary of the Invention

[0003] The purpose of this utility model is to address the shortcomings of the existing technology by providing a rocker arm support adjustment device for a pipe bending machine.

[0004] To achieve the above objectives, the present invention can adopt the following technical solution: The present invention relates to a pipe bending machine rocker arm support adjustment device, comprising a strip-shaped fixed base, an adjustment track on the fixed base, a sliding seat on the adjustment track that slides along its length, a first fixed shaft vertically mounted on the sliding seat, a first rotating seat with an annular structure coaxially mounted at the lower end of the first fixed shaft, a rotating sleeve mounted on the first fixed shaft above the first rotating seat, the rotating sleeve being connected to the first rotating seat and driven by the first rotating seat to rotate around the first fixed shaft, and a rocker arm clamp for clamping the pipe bending machine rocker arm connected to the rotating sleeve; an auxiliary support is provided at one end of the fixed base facing the adjustment track, the upper surface of the auxiliary support being flush with the upper surface of the sliding seat, a second fixed shaft vertically mounted on the auxiliary support corresponding to the first fixed shaft, and a second rotating seat with the same structure as the first rotating seat coaxially mounted at the lower end of the second fixed shaft.

[0005] Furthermore, the adjustment track is a horizontal slide groove formed on the upper surface of the fixed base. A horizontal lead screw is provided in the horizontal slide groove along the length direction. The horizontal lead screw is screwed through the sliding seat and drives the sliding seat to slide along the horizontal slide groove. A drive motor is provided at one end of the horizontal lead screw to drive its rotation, so as to realize the electric translation of the sliding seat while ensuring that it can slide stably along the horizontal slide groove.

[0006] Furthermore, a first threaded hole is provided at the center of the upper end of the first fixed shaft, and a second threaded hole with the same structure as the first threaded hole is provided at the center of the upper end of the second fixed shaft. A scale for measuring the rotation angle of the rotating sleeve is screwed and fixed to the first threaded hole by a connecting bolt, so as to quickly determine the rotation angle of the rocker arm of the pipe bending machine.

[0007] The advantage of this invention lies in the fact that by setting a first fixed shaft on the sliding seat that can be adjusted along the adjustment track and a second fixed shaft on the auxiliary support, the adjustable position of the center of rotation of the pipe bending machine rocker arm can be increased, thereby improving the adjustment range of the pipe bending machine rocker arm. This not only allows it to be used for hot bending of conventional pipe models, but also for hot bending of special pipe models, avoiding the need for splicing special pipe models, improving work efficiency, and enhancing product quality. Attached Figure Description

[0008] Figure 1 This is a schematic diagram of the structure of this utility model. Detailed Implementation

[0009] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0010] like Figure 1 As shown, the bending machine rocker arm support adjustment device of this utility model includes a fixed base 1, which is a strip-shaped structure. An adjustment track 2 is provided on its upper surface along the length direction. A sliding seat 3 is provided on the adjustment track 2 and can slide along its length direction. To ensure that the sliding seat 3 can slide stably along the adjustment track 2, the adjustment track 2 is specifically a horizontal groove 2.1 opened on the upper surface of the fixed base 1. A horizontal lead screw 2.2 is provided in the horizontal groove 2.1 along the length direction. The horizontal lead screw 2.2 is screwed through the sliding seat 3. One end of the horizontal lead screw 2.2 has a drive motor 2.3 to drive its rotation. The drive motor 2.3 drives the horizontal lead screw 2.2 to rotate, thereby enabling the sliding seat 3, which is installed in the horizontal groove 2.1, to slide along the horizontal groove 2.1, realizing the electric control translational movement of the sliding seat 3 and ensuring the movement stability of the sliding seat 3.

[0011] The upper surface of the sliding seat 3 is horizontal, and a first fixed shaft 4 is vertically arranged on it. A first rotating seat 5 with an annular structure is coaxially arranged at the lower end of the first fixed shaft 4. The first rotating seat 5 is fixed to the outer circumference of the first fixed shaft 4, and its upper surface has a rotation drive end. A rotating sleeve 6 is adapted to be installed on the first fixed shaft 4 above the first rotating seat 5. A rocker arm clamp 7 for clamping the rocker arm 100 of the pipe bending machine is connected to the rotating sleeve 6. When the rotating sleeve 6 is fitted on the first fixed shaft 4, its lower end will be connected to the rotation drive end of the first rotating seat 5, so that the rotating sleeve 6 is driven by the first rotating seat 5 to rotate around the first fixed shaft 4, realizing the rotational movement of the rocker arm 100 of the pipe bending machine clamped by the rocker arm clamp 7, and thus realizing the pipe bending process in conjunction with the hot bending of the pipe bending machine.

[0012] In addition, an auxiliary support 8 is provided at one end of the fixed base 1, facing the adjustment rail 2. The upper surface of the auxiliary support 8 is flush with the upper surface of the sliding seat 3. A second fixed shaft 9 corresponding to the first fixed shaft 4 is vertically arranged on the upper surface of the auxiliary support 8. A second rotating seat 10 with the same structure as the first rotating seat 5 is coaxially arranged at the lower end of the second fixed shaft 9. The rotating sleeve 6 together with the rocker arm clamp 7 can be replaced from the first fixed shaft 4 to the second fixed shaft 9 by hoisting, thereby changing the center position of the rocker arm 100 of the pipe bending machine when rotating, increasing the adjustment range of the rocker arm 100 of the pipe bending machine. It can not only adapt to the hot bending of conventional pipe models, but also match the hot bending of special pipe models, avoiding the splicing of special pipe models, improving the working efficiency of pipe bending, and improving product quality.

[0013] Furthermore, to facilitate the rapid determination of the rotation angle of the pipe bending machine rocker arm 100, a first threaded hole 11 should be opened at the center of the upper end of the first fixed shaft 4. A scale 12 for measuring the rotation angle of the rotating sleeve 6 is screwed and fixed to the first threaded hole 11 by a connecting bolt. The upper surface edge of the scale 12 has angle markings, which not only allows for a direct view of the rotation angle of the pipe bending machine rocker arm 100, but also provides a limiting and anti-disengagement stop for the rotating sleeve 6 fitted on the first fixed shaft 4. Of course, a second threaded hole 13 with the same structure as the first threaded hole 11 can also be opened at the center of the upper end of the second fixed shaft 9. In this case, the scale 12 on the first fixed shaft 4 can be removed and installed on the second fixed shaft 9 at any time.

[0014] It should be noted that all directional indicators (such as up, down, left, right, front, back, etc.) in this utility model embodiment are only used to explain the relative positional relationship and movement of each component in a certain specific posture (as shown in the figure). If the specific posture changes, the directional indicator will also change accordingly.

[0015] Furthermore, in this utility model, descriptions involving "first," "second," etc., are for descriptive purposes only and should not be construed as indicating or implying their relative importance or implicitly specifying the number of technical features indicated. Thus, a feature defined as "first" or "second" may explicitly or implicitly include at least one of that feature.
