Description

Technical Field

[0001] This utility model relates to the technical field of welding equipment, specifically a welding device for heat exchanger processing. Background Technology

[0002] A heat exchanger is a device that transfers part of the heat from a hot fluid to a cold fluid. It is also called a heat exchanger. Heat exchangers play an important role in chemical, petroleum, power, food and many other industrial productions. In chemical production, heat exchangers can be used as heaters, coolers, condensers, evaporators and reboilers, etc., and are widely used. In the process of manufacturing heat exchangers, welding equipment is required to fix the heat exchange tubes and complete the welding work of the heat exchange tubes.

[0003] Existing welding equipment mostly uses manual methods to fix heat exchanger tubes, which reduces the fixing efficiency. At the same time, there is no buffer mechanism at the fixing point, which can easily cause deformation of the heat exchanger tubes due to improper operation or excessive clamping force, reducing the practicality of the welding equipment. Therefore, there is a need to propose a welding equipment for heat exchanger processing. Summary of the Invention

[0004] The purpose of this invention is to provide a welding device for heat exchanger processing to solve the problems mentioned in the background art.

[0006] The fixing mechanism includes a vertical plate, a first hydraulic push rod, a plate body, rollers, a placement block, a second hydraulic push rod, a connecting plate, a rod body, a clamping plate, a spring, a motor, a first gear, a second gear, and a ring plate.

The output end of the second hydraulic push rod is fixedly connected to the connecting plate. A rod body is movably connected inside the connecting plate. A clamping plate is fixedly connected to the lower end of the rod body. A spring is fixedly connected to the top of the clamping plate.

[0007] Preferably, a motor is fixedly connected to one side of the bearing housing, and a first gear is fixedly connected to the output end of the motor via a coupling.

[0009] Preferably, a bearing is fixedly connected to the upper end of the threaded rod, and the threaded rod is movably connected to the cylinder through the bearing.

[0011] Preferably, the rod penetrates the interior of the connecting plate and extends to both ends of the connecting plate, and the rod is movably connected to the connecting plate.

[0012] Compared with the prior art, the beneficial effects of this utility model are:

[0013] 1. This welding device for heat exchanger processing, in conjunction with a fixing mechanism, involves placing the heat exchange tube on a placement block, then activating a second hydraulic push rod to lower the clamping plate and bring it into contact with the outer wall of the heat exchange tube. Simultaneously, a connecting plate descends, compressing a spring and causing the rod to extend in the reverse direction within the connecting plate, thus providing buffer clamping for the heat exchange tube. The first hydraulic push rod can then move the heat exchange tube towards the welding torch for easier welding. Furthermore, the starting of a motor drives the rotation of a first gear, which, through the meshing of the first and second gears, causes the welding torch to rotate, achieving the welding of the heat exchange tube. This improves the efficiency and protection of the heat exchange tube clamping, while also increasing the welding efficiency, thereby enhancing the practicality of the welding device.

[0014] 2. This welding device for heat exchanger processing, through the setting of the adjustment mechanism, drives the rotation of the threaded rod by rotating the handle during the use of the device, and through the mutual meshing of the threaded rod and the ring plate, drives the height adjustment of the welding torch, thereby improving the welding effect and accuracy of the heat exchange tube, and thus improving the applicability of the welding device to a certain extent.

The vertical plate 301 is fixedly connected to the top of the base plate 1. The first hydraulic push rod 302 is fixedly connected to one side of the vertical plate 301. The output end of the first hydraulic push rod 302 is fixedly connected to the plate 303. There are two plates 303, symmetrically arranged about the vertical axis of the bearing seat 2, facilitating the movement of the two fixed heat exchange tubes and improving the efficiency of welding the heat exchange tubes. The roller 304 is movably connected to the bottom of the plate 303. The placement block 305 is fixedly connected to the inner bottom wall of the plate 303. The upper part of the plate 303 is fixedly connected to the roller 304. A second hydraulic push rod 306 is fixedly connected. A connecting plate 307 is fixedly connected to the output end of the second hydraulic push rod 306. A rod 308 is movably connected inside the connecting plate 307. The rod 308 passes through the interior of the connecting plate 307 and extends to both ends of the connecting plate 307. The rod 308 is movably connected to the connecting plate 307, which facilitates the adjustment of the distance between the clamping plate 309 and the connecting plate 307 as the clamping plate 309 fixes the heat exchange tube, thus facilitating the buffer clamping of the heat exchange tube. The clamping plate 309 is fixedly connected to the lower end of the rod 308. A spring 310 is fixedly connected to the upper part of the clamping plate 309. A motor 311 is fixedly connected to one side of the bearing seat 2. A first gear 312 is fixedly connected to the output end of the motor 311 through a coupling. A second gear 313 is movably connected to the outer wall of the first gear 312. A ring plate 314 is fixedly connected to the inner wall of the second gear 313.

[0023] Please see Figure 1-4 The adjusting mechanism 4 includes a threaded rod 401, a handle 402, and a cylinder 403. The threaded rod 401 is movably connected inside the ring plate 314. A bearing is fixedly connected to the upper end of the threaded rod 401.

The handle 402 is fixedly connected to the lower end of the threaded rod 401, and the cylinder 403 is movably connected to the upper end of the threaded rod 401.

[0024] Working principle: When using the welding device for heat exchanger processing, firstly, place the heat exchange tube in a suitable position on the placement block 305, then activate the second hydraulic push rod 306 to lower the height of the connecting plate 307. At the same time, the clamping plate 309 simultaneously lowers in height and contacts the outer wall of the heat exchange tube. As the connecting plate 307 continues to descend, it compresses the spring 310, causing the rod 308 to extend in the reverse direction inside the connecting plate 307, achieving buffer clamping of the heat exchange tube. Then, activate the first hydraulic push rod 302 to move the position of the plate 303, simultaneously causing the roller 304 at the bottom of the plate 303 to roll on the base plate 1, and moving the heat exchange tube towards the position of the welding torch 5. After the heat exchange tubes are moved to the appropriate positions, the handle 402 is rotated, which drives the threaded rod 401 to rotate. Then, through the meshing of the threaded rod 401 with the internal threaded hole of the ring plate 314, the height of the welding torch 5 is adjusted. Then, the motor 311 is started, which drives the first gear 312 to rotate. Then, through the meshing of the first gear 312 and the second gear 313, the ring plate 314 is rotated, thereby driving the welding torch 5 to move in a circular motion, so as to achieve the welding work between the heat exchange tubes. The first hydraulic push rod 302 is model DTL, the second hydraulic push rod 306 is model DTL, and the motor 311 is model YL90L-2. In this way, the use of the welding device for heat exchanger processing is completed.
