Description

Technical Field

[0001] This utility model relates to the technical field of pipe bending welding devices, specifically a high-sealing segmented pipe bending welding assembly. Background Technology

[0002] Segmented pipe bending welding equipment is a device used in industrial pipeline manufacturing to weld and fix bends between straight pipes. Based on the principles of electric arc heating, laser melting, or electron beam melting, it melts and combines the base material with the filler material (such as welding wire or welding powder) to form a continuous weld. Its applications cover multiple industries such as petroleum, chemical, power, shipbuilding, and aerospace, and it is a key device to ensure the safe and reliable operation of industrial pipeline systems.

[0003] Existing pipe bending welding devices, such as the irregular pipe bending welding clamping device disclosed in publication number CN219358481U, have the advantage of being able to weld pipes of various sizes, angles and diameters. However, with this device, the fixed pipe is not easy to automatically rotate and adjust during welding, which makes it difficult to weld the entire circle of pipes together. Therefore, we propose a high-sealing segmented pipe bending welding assembly. Utility Model Content

[0004] This utility model aims to solve one of the technical problems existing in the prior art or related technologies.

[0005] Therefore, the technical solution adopted by this utility model is as follows: A high-sealing segmented pipe bending welding assembly includes: a welding device and a fixing component; the welding device includes a workbench and a control panel fixedly installed on the workbench; the fixing component includes a left fixed arm and a right fixed arm fixedly installed on both sides of the workbench, a left fixed shaft and a right fixed shaft rotatably connected to one side of the left fixed arm and the right fixed arm, driven pulleys fixedly installed on both the left fixed shaft and the right fixed shaft, a left fixed seat and a right fixed seat fixedly installed on one side of the left fixed shaft and the right fixed shaft, and a left positioning groove and a right positioning groove respectively opened in the left fixed seat and the right fixed seat.

[0006] Preferably, a left pressure block and a right pressure block are movably installed on the outer sides of the left positioning groove and the right positioning groove, respectively, and a left connecting plate and a right connecting plate are fixedly installed on the outer ends of the left pressure block and the right pressure block, respectively.

[0007] Preferably, both the left and right connecting plates are fixedly connected with connecting rods, and both the left and right pressure blocks are provided with binding openings, with the connecting rods movably installed in the binding openings.

[0008] Preferably, each of the connecting rods is also movably fitted with a spring at its outer end.

[0009] Preferably, a dual-shaft reducer is also fixedly installed on the workbench, and a drive pulley is fixedly installed at both ends of the dual-shaft reducer. A synchronous belt is also meshed between the drive pulley and the driven pulley.

[0010] Preferably, a left pipe fitting and a right pipe fitting are movably installed in the left positioning groove and the right positioning groove, respectively.

[0011] Preferably, the driving pulley and the driven pulley are the same size.

[0012] By adopting the above technical solution, the beneficial effects achieved by this utility model are as follows: In this invention, the left and right pipe fittings within the left and right fixed seats on the workbench can rotate slowly and synchronously under the transmission of a dual-axis reducer, thereby completing the convenient welding between the left and right pipe fittings during rotation and improving the welding convenience. At the same time, the left and right positioning grooves within the left and right fixed seats, as well as the left and right pressure blocks pressed against the outer ends of the left and right positioning grooves, can accurately position the left and right pipe fittings while also pressing them to ensure the stability during welding, thereby improving the welding quality. Furthermore, the disassembly and assembly of the left and right pipe fittings before and after welding are also relatively convenient. Attached Figure Description

[0015] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to specific embodiments and accompanying drawings. It should be noted that, unless otherwise specified, the embodiments and features of the present utility model can be combined with each other.

[0016] The following describes, with reference to the accompanying drawings, some embodiments of the present invention, providing a high-sealing segmented pipe bending welding assembly.

[0017] Example 1: Combination Figure 1-5 As shown, this utility model provides a high-sealing segmented pipe bending welding assembly, comprising: a welding device 100 and a fixing assembly 200; the welding device 100 includes a workbench 101 and a control panel 102 fixedly installed on the workbench 101; the fixing assembly 200 includes a left fixing arm 201 and a right fixing arm 202 fixedly installed on both sides of the workbench 101, a left fixing shaft 203 and a right fixing shaft 204 rotatably connected to one side of the left fixing arm 201 and the right fixing arm 202, driven pulleys 205 fixedly installed on both the left fixing shaft 203 and the right fixing shaft 204, a left fixing seat 206 and a right fixing seat 207 fixedly installed on one side of the left fixing shaft 203 and the right fixing shaft 204, and left positioning grooves 208 and right positioning grooves 209 respectively opened in the left fixing seat 206 and the right fixing seat 207, and further positioning grooves 208 and 209 respectively on the outer sides of the left positioning grooves 208 and the right positioning grooves 209. A left pressure block 210 and a right pressure block 211 are movably installed. A left connecting plate 212 and a right connecting plate 213 are respectively fixedly installed on the outer ends of the left pressure block 210 and the right pressure block 211. A connecting rod 214 is fixedly connected to both the left connecting plate 212 and the right connecting plate 213. A restraint opening 215 is provided inside both the left pressure block 210 and the right pressure block 211, and the connecting rod 214 is movably installed in the restraint opening 215. The outer ends of the connecting rods 214 are also movably installed... The worktable 101 is equipped with a spring 216 and a dual-shaft reducer 217 is fixedly installed on it. Both ends of the dual-shaft reducer 217 are fixedly installed with drive pulleys 218. The drive pulleys 218 and driven pulleys 205 are also meshed with synchronous belts 219. The left positioning groove 208 and the right positioning groove 209 are respectively movably installed with left pipe fittings 220 and right pipe fittings 221. The drive pulleys 218 and driven pulleys 205 are the same size.

[0018] Specifically, the segmented pipe bending welding device is a piece of equipment used in industrial pipe manufacturing to achieve welding and fixing between bent and straight pipes. The left pipe fitting 220 and right pipe fitting 221 within the left fixed seat 206 and right fixed seat 207 on the workbench 101 can slowly and synchronously rotate under the drive of the dual-shaft reducer 217, thus completing the convenient welding between the left pipe fitting 220 and right pipe fitting 221 during rotation, improving welding convenience. Simultaneously, the left positioning groove 208 and right positioning groove 209 within the left fixed seat 206 and right fixed seat 207, as well as the left pressure block 210 and right pressure block 211 pressing against the outer ends of the left and right positioning grooves 208 and 209, can precisely position and press the left pipe fitting 220 and right pipe fitting 221, ensuring stability during welding, improving the high sealing performance between the left pipe fitting 220 and right pipe fitting 221 after welding, and thus effectively increasing welding quality. Furthermore, the disassembly and assembly of the left pipe fitting 220 and the right pipe fitting 221 before and after welding are relatively convenient. The synchronous belt 219 installed between the driven pulley 205 and the driving pulley 218 is mainly used for the synchronous transmission of the left fixed shaft 203 and the right fixed shaft 204 at both ends, thereby realizing the synchronous rotation of the left fixed seat 206 and the right fixed seat 207, ensuring the welding quality. The left positioning groove 208 and the right positioning groove 209 in the left fixed seat 206 and the right fixed seat 207 are mainly used for the synchronous transmission of the left fixed shaft 203 and the right fixed shaft 204 at both ends, thereby realizing the synchronous rotation of the left fixed seat 206 and the right fixed seat 207, ensuring the welding quality. For positioning and installation before welding the left pipe fitting 220 and the right pipe fitting 221, the left pressure block 210 and the right pressure block 211 are pressed against the left pipe fitting 220 and the right pipe fitting 221 in the left positioning groove 208 and the right positioning groove 209 by the elastic force of the spring 216 on the connecting rod 214, so as to ensure their stability during welding. At the same time, the left pipe fitting 220 and the right pipe fitting 221 can be disassembled and adjusted simply by pulling the left pressure block 210 and the right pressure block 211.

[0019] Working principle and usage process of this utility model: Before welding the left pipe fitting 220 and the right pipe fitting 221, first pull out the left pressure block 210 and the right pressure block 211 on the left fixing seat 206 and the right fixing seat 207 in sequence to position and install the left pipe fitting 220 and the right pipe fitting 221 into the left positioning groove 208 and the right positioning groove 209 respectively. Then, release the left pressure block 210 and the right pressure block 211. Under the elastic force of the rear spring 216, the left pressure block 210 and the right pressure block 211 will press against the left positioning groove 208. The left pressure block 210 and right pressure block 211 in the right positioning groove 209 are pressed and fixed. Finally, the dual-shaft reducer 217 is started so that the driven pulleys 205 on both sides of the upper end can be synchronously driven through the synchronously rotating drive pulleys 218 at both ends. This synchronously rotates the left pressure block 210 and right pressure block 211 in the left fixed seat 206 and right fixed seat 207 to perform automatic and precise rotational welding between the left pressure block 210 and right pressure block 211.
