Description

Technical Field

[0001] The utility model relates to the technical field of bent pipe processing, in particular to a support structure for a bent pipe spot welder. Background Art

[0002] In order to cool or heat the medium in a pressure vessel, semi-bent pipes are usually wound and welded on the outer shell of the vessel. The manufacturing process is as follows: first, a steel strip is continuously processed on a pipe bender to form a bent semi-pipe, and then the semi-pipe is wound around the cylinder body for several turns. The final butt weld is a continuous spiral circumferential weld.

[0003] In the above processing process, the cylinder body needs to be rotationally supported. Since the bent pipe will be subjected to unstable forces during winding, the cylinder body may fall off the rotational support. Based on this, this solution provides a support structure for a bent pipe spot welder. Summary of the Utility Model

[0004] The purpose of the utility model is to provide a support structure for a bent pipe spot welder, and this solution solves the problem of unstable support during the processing.

[0005] To achieve the above purpose, the utility model provides the following technical solution: A support structure for a bent pipe spot welder has a semi-pipe bender, which is used to bend the semi-pipe so that the semi-pipe fits the cylinder body. It also includes a first support assembly, a second support assembly, and a third support assembly. The third support assembly is used to support both ends of the cylinder body. The first support assembly and the second support assembly are located on both sides of the cylinder body and are both in the same radial cross-section of the cylinder body. The first support assembly and the second support assembly are set to be interlocked. The second support assembly is provided with a multi-axis slide table module, and the semi-pipe bender is installed on the multi-axis slide table module. The first support assembly has a base, on which a support part is hinged. The support part is provided with a lifting module and a rolling body, and the rolling body is installed on the lifting module. The rolling body is in sliding contact with the cylinder body; the base also has a driving component, and the driving component is used to drive the support part to rotate around the hinge point.

[0006] The above technical solution sets the first support assembly, the second support assembly, and the third support assembly. The first support assembly and the second support assembly are respectively located on both sides of the cylinder body, and the third support assembly is used to support both ends of the cylinder body. At the same time, the first support assembly has a support part and a lifting module. The support part can adjust the angle so that the rolling body on the lifting module abuts against the side of the cylinder body. The first support assembly and the second support assembly can move along the axial direction of the cylinder body at the same time, ensuring that when the semi-pipe is wound around the cylinder body, the first support assembly can provide sufficient support force for the cylinder body and improve the stability during the winding process of the semi-pipe.

[0007] The supporting part includes a supporting arm, and the lifting module includes a lifting arm fixedly connected to the supporting arm. A first lead screw is provided on the lifting arm, and a first motor for driving the first lead screw is provided at the top end of the lifting arm.

A supporting frame is connected to the slider plate, and a first nut block adapted to the first lead screw is connected to the supporting frame. The rolling element is a first roller, and a first support for mounting the first roller is connected to the supporting frame.

[0008] In the above technical solution, the supporting part of the supporting arm is adopted, and the lifting arm is connected to the supporting arm. Linear slide rails and linear sliders are used on the lifting arm to fit and connect the first roller. The first roller is used for rolling contact with the side surface of the cylinder body. When the cylinder body winds the half pipe, the first roller can provide support for the side of the cylinder body away from the pipe bender, ensuring the stability of the half pipe during winding.

[0009] A first guiding rod is provided on the supporting frame in a direction perpendicular to the linear slide rail. One end of the first guiding rod is fixedly connected to the first support, and a first cylinder is also installed on the supporting frame. The output end of the first cylinder is fixedly connected to the first support.

[0010] In the above technical solution, the first guiding rod is connected to the first support. The first support can be adjusted to extend or shorten by the first cylinder, and then cooperate with the supporting arm that can rotate, so as to adapt to cylinders of different sizes.

[0014] The driving assembly of the above technical solution has a worm gear screw lift. After starting the worm gear screw lift, the screw of the worm gear screw lift can pull or push the support arm to make a circular motion, thereby completing the support of the first roller on the side of the cylinder.

[0015] The multi-axis slide module is a dual-axis slide module, which includes a first track, a first slide and a second slide. The first track is arranged along the length direction of the cylinder, the first track is coupled to the first slide, and the first slide is coupled to the second slide perpendicular to the length direction of the cylinder.
