Description

A flip-type stainless steel pipe vertical welding tool Technical Field

[0001] The utility model belongs to the technical field of stainless steel pipes, and particularly relates to a turnover type stainless steel pipe vertical welding tool. Background Art

[0002] Stainless steel is the abbreviation of stainless acid-resistant steel. Steel that is resistant to weak corrosive media such as air, steam, and water or has rust resistance is called stainless steel; and steel that is resistant to chemical corrosive media (acid, alkali, salt, etc.) is called acid-resistant steel.

[0003] When welding vertical bends in stainless steel, two straight stainless steel pipes and one vertical stainless steel pipe are required, and then they are positioned and welded. However, the positioning method of traditional welding positioning tooling has poor stability, and single positioning generally only allows for single-side welding. The other side also needs to be repositioned, which is time-consuming, labor-intensive, and inefficient. Utility Model

[0004] In order to solve the above problems existing in the prior art, the utility model provides a flip-type stainless steel pipe vertical welding tool, which has the characteristics of improving stand-in welding efficiency and enhancing positioning effect.

[0005] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a flip-type stainless steel pipe vertical welding tool, comprising a welding table, a flip frame is provided on the welding table, a base plate is fixedly provided at one end of the flip frame, a combination frame is fixedly provided at the other end of the base plate, a straight pipe cylinder is fixedly provided inside the combination frame, a straight pipe clamp is fixedly provided at the output end of the straight pipe cylinder, a straight pipe clamp seat is fixed on the inside of the flip frame, a bending pipe cylinder is also provided inside the combination frame, a bending pipe clamp is fixedly provided at the output end of the bending pipe cylinder, a bending pipe clamp seat is also provided on the inside of the flip frame, a guide plate is fixedly provided on the end of the bending pipe clamp away from the base plate, and a flip assembly is also provided between the welding table and the flip frame.

[0006] As an optimal technical solution for a flip-type stainless steel pipe vertical welding tooling of the utility model, the flip assembly includes a flip seat fixedly mounted on the welding table, a flip shaft fixed at one end of the outer side of the flip frame, and a flip motor fixedly mounted at one end of the welding table.

[0007] As an optimal technical solution for a flip-type stainless steel pipe vertical welding tooling of the utility model, the flip shaft rotates inside the flip seat and is fixedly installed with the output end of the flip motor. The flip motor drives the flip shaft to rotate back and forth through the PLC.

[0008] As an optimal technical solution for a flip-type stainless steel pipe vertical welding tooling of the utility model, the flip frame is vertically arranged, the straight pipe cylinder, straight pipe splint, and straight pipe clamp seat are two groups distributed at the two ends of the inner side of the flip frame, and the bent pipe cylinder, bent pipe splint, and bent pipe clamp seat are a group distributed at the angle of the flip frame.

[0009] As an optimal technical solution for a flip-type stainless steel pipe vertical welding tooling of the utility model, the straight pipe splint and straight pipe clamp seat match the surface contour of the straight pipe, and the bent pipe splint and bent pipe clamp seat match the inner and outer corner contours of the bent pipe.

[0010] As an optimal technical solution of the flip-type stainless steel pipe vertical welding tooling of the utility model, the guide plate squeezes the bent pipe between the guide plate and the bottom plate.

[0011] Compared with the existing technology, the beneficial effects of the present invention are: the present invention adopts a multi-directional cylinder to simultaneously position the straight pipe and the bent pipe, which is highly convenient and can also ensure the stable positioning effect. The bent pipe is also limited in direction at both ends while being positioned, ensuring that the entire bent pipe is in a horizontal state, thereby ensuring welding accuracy. At the same time, a flip assembly is provided, which facilitates welding on the other side of the pipe. It is simple, practical, convenient and efficient. BRIEF DESCRIPTION OF THE DRAWINGS

[0018] The following will be combined with the accompanying drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention. Example

[0019] Please refer to Figures 1-4. The utility model provides the following technical solutions: a flip-type stainless steel pipe vertical welding tool, including a welding table 1, a flip frame 2 is provided on the welding table 1, a base plate 3 is fixedly provided at one end of the flip frame 2, a combination frame 4 is fixedly provided at the other end of the base plate 3, a straight pipe cylinder 5 is fixedly provided inside the combination frame 4, a straight pipe clamp 6 is fixedly provided at the output end of the straight pipe cylinder 5, a straight pipe clamp seat 7 is fixed on the inside of the flip frame 2, a bending cylinder 8 is also provided inside the combination frame 4, a bending clamp 9 is fixedly provided at the output end of the bending cylinder 8, a bending clamp seat 10 is also provided on the inside of the flip frame 2, a guide plate 11 is fixedly provided at the end of the bending clamp 9 away from the base plate 3, and a flip assembly is also provided between the welding table 1 and the flip frame 2.

[0020] Specifically, the flip assembly includes a flip seat 12 fixedly mounted on the welding table 1, a flip shaft 13 fixed at one end of the outer side of the flip frame 2, and a flip motor 14 fixedly mounted at one end of the welding table 1. The flip shaft 13 rotates inside the flip seat 12 and is fixedly mounted to the output end of the flip motor 14. The flip motor 14 drives the flip shaft 13 to rotate back and forth 180° through the PLC. In this embodiment, the flip assembly enhances the convenience of welding.

[0021] Specifically, the turning frame 2 is vertically arranged, and the straight tube cylinder 5, straight tube splint 6, and straight tube clamp seat 7 are distributed in two groups at the two ends of the inner side of the turning frame 2, and the bent tube cylinder 8, bent tube splint 9, and bent tube clamp seat 10 are distributed in a group at the angle of the turning frame 2.

[0022] Specifically, the straight tube splint 6 and the straight tube clamp seat 7 match the surface contour of the straight tube, and the bent tube splint 9 and the bent tube clamp seat 10 match the inner and outer corner contours of the bent tube. In this embodiment, the straight tube splint 6 and the straight tube clamp seat 7 can also move axially after clamping the straight tube, which facilitates docking with the welding end of the bent tube.

[0023] Specifically, the guide plate 11 squeezes the bent pipe between the guide plate 11 and the bottom plate 3. In this embodiment, the bottom plate 3 and the guide plate 11 limit the welding end of the bent pipe to be in a horizontal state, which is convenient for precise docking with the straight pipe, thereby ensuring welding accuracy.

[0024] The working principle and usage process of the utility model are as follows: the bent pipe is leaned against the inner side of the bent pipe clamp seat 10, and the straight pipe is leaned against the inner side of the straight pipe clamp seat 7, and the straight pipe cylinder 5 and the bent pipe cylinder 8 are started at the same time. The telescopic end of the straight pipe cylinder 5 drives the straight pipe clamp plate 6 to clamp the straight pipe, and the telescopic end of the bent pipe cylinder 8 drives the bent pipe clamp plate 9 to clamp the bent pipe. At this time, the position of the straight pipe is adjusted according to the distance between the bent pipe welding end and the straight pipe, and welding can be started when the welding end is completely docked. After the upper end is welded, the flip motor 14 drives the flip shaft 13 to rotate, and the flip shaft 13 drives the flip frame 2 to rotate on the flip seat 12. After flipping 180°, the unwelded end is located at the top, and the unwelded part is welded. After the welding is completed, the flip frame 2 is rotated and reset to break away from the clamping of the cylinder, and then the welded vertical pipe can be removed.

[0025] Finally, it should be noted that the above description is merely a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art will be able to modify the technical solutions described in the aforementioned embodiments or replace some of the technical features therein with equivalents. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principles of the present invention shall be included within the scope of protection of the present invention.
