Description

Technical Field

[0001] This invention relates to the technical field of metal welding, and in particular to a plasma arc welding machine and method for metal products. Background Technology

[0002] A plasma arc is a high-temperature ionized gas stream generated by ionization of ionized gas. It is ejected from a nozzle orifice and compressed to form a slender arc column. Plasma arcs are characterized by their slender arc column and high energy density, and are widely used in the welding field. As a welding device, during the welding preparation process, the metal products to be welded need to be fixed, and then the welding position needs to be adjusted to ensure the accuracy of the welding position. After welding is completed, the welding power is turned off and the device is allowed to cool down.

[0003] However, during the welding preparation process, the welding position cannot be adjusted simultaneously when the welding is fixed. The welding equipment is too heavy, making it too troublesome to adjust its position. At the same time, it is impossible to rotate or flip the metal products during the welding process, which usually requires manual handling. Because the equipment temperature is high during the welding process, operators are prone to injury. Natural cooling during welding is relatively slow, and cracks and damage are prone to occur at the weld joint, affecting the service life of the equipment. Summary of the Invention

[0040] Many specific details are set forth in the following description in order to provide a full understanding of the invention.

[0043] Example 1

[0044] Reference Figures 1-10 The first embodiment of the present invention provides a plasma arc welding method for hardware products, which achieves the effects of flipping adjustment, weld cooling and cooling liquid control through a plasma arc welding machine and method for hardware products.

[0045] When the support mechanism 100 starts, it drives the fixing mechanism 200 to fix the workpiece, avoiding the synchronization problem that occurs when the fixing mechanism 200 uses multiple drive devices, thus achieving smooth start-up and operation. Simultaneously, it also drives the tilting mechanism 300 to tilt, ensuring the workpiece is firmly fixed in the predetermined position during welding. When the support mechanism 100 starts, it transmits power to the fixing mechanism 200 through a transmission device, causing the clamping device to act quickly and fix the workpiece.

[0046] When the suction mechanism 500 is activated, it can drive the cooling mechanism 400 to work. The suction mechanism 500 sucks in the fumes generated during the welding process through the pipe and collects them, so as to avoid directly throwing harmful gases into the environment and reduce environmental pollution. The cooling mechanism 400 prevents the weld joint from cracking and being damaged due to continuous high temperature.

[0047] The liquid control component 406 can control the cooling mechanism 400. When the cooling mechanism 400 does not need to work, the liquid control component 406 can automatically shut off the supply to avoid leakage.

[0048] Example 2

[0049] Reference Figures 5-9 In the second embodiment of the present invention, a flipping mechanism 300 is provided, which enables the rotational adjustment of the welded parts.

[0050] The flipping mechanism 300 includes a first flipping plate 301, the bottom of the first flipping plate 301 is movably connected to the inner wall of the first C-shaped plate 209, the inner wall of the second C-shaped plate 212 is movably connected to a second flipping plate 302, the right side of the first flipping plate 301 is fixedly connected to a transmission assembly 303, the bottom of the plasma arc welding device 105 is fixedly connected to a cooling mechanism 400, the front end of the support block 103 is fixedly connected to a suction mechanism 500, and the top of the processing table 102 is fixedly connected to a linkage mechanism 600.

[0051] The linkage mechanism 600 includes a pad 601, a U-shaped plate 602 fixedly connected to the top of the pad 601, a movable rod 603 movably connected to the inner cavity of the U-shaped plate 602, the top and bottom of the movable rod 603 penetrating the inner wall and bottom of the U-shaped plate 602, a first linkage gear 604 fixedly connected to the top of the movable rod 603, a second linkage gear 605 movably connected to the bottom of the inner wall of the U-shaped plate 602 and corresponding to the left side of the first linkage gear 604 via a rotating shaft, a first rotating column 606 movably connected to the left side of the inner cavity of the U-shaped plate 602, a third linkage gear 607 fixedly connected to the right side of the first rotating column 606 penetrating the inner wall of the U-shaped plate 602, and a third linkage gear 607 movably connected to the right side of the inner cavity of the U-shaped plate 602. A second rotating column 608 is dynamically connected. A fourth connecting gear 609 is fixedly connected to the left side of the second rotating column 608 through the inner wall of the U-shaped plate 602. The left and right sides of the second connecting gear 605 are meshed with the bottom of the third connecting gear 607 and the left side of the first connecting gear 604. The bottom of the fourth connecting gear 609 is meshed with the right side of the first connecting gear 604. A cross solid rod 610 is fixedly connected to the left side of the first rotating column 606 and the right side of the second rotating column 608 through the left and right sides of the U-shaped plate 602. A C-shaped hollow rod 611 is slidably connected to the top of the cross solid rod 610. The right side of the C-shaped hollow rod 611 is fixedly connected to the left side of the transmission assembly 303.

[0052] The transmission assembly 303 includes a metal connecting plate 303a. The left side of the metal connecting plate 303a is fixedly connected to the right side of the first tilting plate 301. The right side of the metal connecting plate 303a is movably connected to the first transmission shaft 303b via a rotating shaft. The right side of the first transmission shaft 303b is movably connected to the metal support plate 303c via a rotating shaft. The back end of the left side of the metal support plate 303c is movably connected to the second transmission shaft 303d via a rotating shaft. The left side of the second transmission shaft 303d is fixedly connected to the right side of the C-shaped hollow rod 611. The second transmission shaft and the first transmission shaft 303b are connected by track drive.

[0053] The gear assembly 202g includes a first circular plate 202g-1. The top of the first circular plate 202g-1 is movably connected to the top of the inner wall of the processing table 102 via a rotating shaft. A second meshing gear 202g-2 is fixedly connected to the bottom of the first circular plate 202g-1. A second circular plate 202g-3 is fixedly connected to the bottom of the movable rod 603. The second circular plate 202g-3 and the first circular plate 202g-1 are connected by a track drive.

[0054] Specifically, the first flip plate 301 and the second flip plate 302 can be flipped according to welding requirements, so that the plasma arc welding device 105 can weld the workpiece at different angles. This greatly improves the flexibility of welding and can adapt to the welding requirements of workpieces with various complex shapes.

[0055] Specifically, the first connecting gear 604, the second connecting gear 605, the third connecting gear 607, and the fourth connecting gear 609 mesh with each other to form a stable and precise transmission system. This multi-gear design ensures the accuracy of the transmission ratio, making the third connecting gear 607 and the fourth connecting gear 609 rotate in the same direction.

[0056] Specifically, when the linkage mechanism 600 transmits power to the transmission assembly through the C-shaped hollow rod 611, the transmission assembly 303 can quickly transmit the power to the first flipping plate 301 to achieve control of the flipping angle.

[0057] Specifically, the top of the first circular plate 202g-1 and the top of the inner wall of the processing table 102 are movably connected by a rotating shaft, and the second circular plate 202g-3 and the first circular plate 202g-1 are connected by a track drive, which can work in conjunction with the fixing mechanism 200, the flipping mechanism 300 and the linkage mechanism 600.

[0058] Furthermore, the workpiece to be welded is placed on the first flip plate 301 and the second flip plate 302 and fixed by the fixing mechanism 200. Then, it can be rotated and adjusted by the movable connection of the first flip plate 301 and the second flip plate 302.

[0059] Furthermore, the rotation of the movable rod 603 drives the first connecting gear 604 to rotate, and the rotation of the first gear 604 drives the second connecting gear 605, the third connecting gear 607, and the fourth connecting gear 609 to rotate. The third connecting gear 607 and the fourth connecting gear 609 rotate in the same direction. The rotation of the third connecting gear 607 and the fourth connecting gear 609 drives the solid cross rod 610 and the hollow C-shaped rod 611 on both sides to rotate, so as to meet the adjustment requirements of the welding point position during the welding process.

[0060] Furthermore, the C-shaped hollow rod 611, connected to the transmission assembly 303, begins to move under the action of the linkage mechanism 600. Since the left side of the second transmission shaft 303d is fixedly connected to the C-shaped hollow rod 611, the C-shaped hollow rod 611 drives the second transmission shaft 303d to rotate. After the second transmission shaft 303d rotates, it drives the first transmission shaft 303b to rotate through the track. The first transmission shaft 303b transmits power to the first tilting plate 301 through the metal connecting plate 303a, thereby realizing the control of tilting adjustment.

[0061] Furthermore, the first control gear 202f meshes with the second engagement gear 202g-2, thereby driving the second engagement gear 202g-2 to rotate. The rotation of the second engagement gear 202g-2 drives the first circular plate 202g-1 to rotate, and through the transmission track, drives the second circular plate 202g-3. This enables the connection of the tilting and adjusting components, realizing the rotational adjustment of the welded parts during the welding process.

[0062] Example 3

[0063] Reference Figure 3 and 4 In the third embodiment of the present invention, a cooling mechanism 400 is provided, which achieves the effect of rapid cooling of the weld joint.

[0064] The cooling mechanism 400 includes a fixing block 401. The top of the fixing block 401 is fixedly connected to the bottom of the plasma arc welding device 105. The inner cavity of the fixing block 401 is provided with an inlet pipe 402 and an outlet pipe 403. The inlet pipe 402 is located on the left side of the outlet pipe 403. A cooling heat pipe 404 is fixedly connected to the front end of the inlet pipe 402. A section of the cooling heat pipe 404 away from the inlet pipe 402 is fixed to the front end of the outlet pipe 403. The cooling heat pipe 404 is located on the top of the surface of the welding nozzle 106. A liquid storage tank 405 is provided at the bottom of the inlet pipe 402 and the outlet pipe 403. The back end of the liquid storage tank 405 is fixedly connected to the front end of the support block 103. A liquid control component 406 is provided in the inner cavity of the liquid storage tank 405.

[0065] The liquid control assembly 406 includes a liquid control plate 406a, which is disposed in the inner cavity of the liquid storage tank 405. A liquid control slider 406b is fixedly connected to the back end of the liquid control plate 406a. A pipe plug 406c is fixedly connected to the left and right sides of the top of the liquid control slider 406b, corresponding to the positions of the inlet pipe 402 and the outlet pipe 403. A first spring block 406d is fixedly connected to the left and right sides of the bottom of the liquid control plate 406a. A support spring 406e is fixedly connected to the bottom of the first spring block 406d. A second spring block 406f is fixedly connected to the bottom of the support spring 406e. The bottom of the second spring block 406f is fixedly connected to the top of the processing table 102.

[0066] Specifically, the inlet pipe 402 is responsible for introducing coolant into the cooling heat pipe 404, while the outlet pipe sends the coolant that has absorbed heat back to the storage tank 405, forming a circulation flow to achieve continuous cooling, effectively reducing the temperature of the welding nozzle, preventing damage to the welding nozzle due to high temperature, and extending its service life.

[0067] Specifically, the inlet pipe 402 and outlet pipe 403 can be adjusted according to the welding process. They are controlled by the liquid control plate 406a. When the liquid control plate 406a is under pressure, the inlet pipe 402 and outlet pipe 403 can flow to cool the welding nozzle 106.

[0068] Furthermore, coolant flows from the reservoir 405 into the cooling heat pipe 404 through the inlet pipe 402. Since the cooling heat pipe 404 is located on the top of the welding nozzle 106, it can quickly absorb the heat generated by the welding nozzle. The coolant that has absorbed the heat then flows back to the reservoir 405 through the outlet pipe 403, ensuring that the welding nozzle will not crack or be damaged.

[0069] Furthermore, the welded component presses down on the lower liquid control plate 406a, causing the liquid control slider 406b and the pipe plug 406c to move synchronously, opening the channels of the liquid inlet pipe 402 and the liquid outlet pipe 403 to allow flow. When the welding work is finished and the welded component is removed, the support spring 406e automatically resets and blocks the flow hole to prevent leakage when not in operation, thus avoiding unnecessary consumption of coolant.

[0070] The remaining structure is the same as that in Example 2.

[0071] Example 4

[0072] Reference Figures 1-10 This is the fourth embodiment of the present invention, which differs from the third embodiment in that: this embodiment provides a plasma arc welding machine for hardware products.

[0073] When preparing to perform welding work, the metal products to be welded are placed in the first flip plate 301. Then, the elevator 104 is started to drive the plasma arc welding device 105, welding nozzle 106, cooling mechanism 400, solid plate 210, hollow plate 211, second C-shaped plate 212 and second flip plate 302 to move downwards and fix the welded parts.

[0074] The start-up drive motor 202a drives the first pinion 202b to rotate. The rotation of the first pinion 202b drives the second pinion 202d and the third pinion 202e to rotate, and simultaneously drives the second control gear 202h and the first engaging gear 202i to rotate. The rotation of the first engaging gear 202i drives the first toothed plate 205 and the second toothed plate 206 to move in opposite directions. At the same time, it drives the connecting plate 207, the connecting block 208, the first C-shaped plate 209, the second C-shaped plate, the first flipping plate 301, the second flipping plate 302, the metal connecting plate 303a, the first drive shaft 303b, the metal support plate 303c, the second drive shaft 303d, and the C-shaped hollow rod 611 to move through the cross solid rod 610, so that the left and right welded parts are clamped towards the middle to avoid large weld seams during welding.

[0075] When the welded parts need to be rotated, the small cylinder 201 moves the drive motor 202a upward a short distance, causing the second control gear 202h and the first engaging gear 202i to disengage. Simultaneously, the first control gear 202f moves upward to engage with the second engaging gear 202g-2, thereby driving the second engaging gear 202g-2 to rotate. The rotation of the second engaging gear 202g-2 causes the first circular plate 202g-1 to rotate, which in turn drives the second circular plate 202g-3, the movable rod 603, and the first connecting gear 604 to rotate via the transmission track. The rotation of the first gear 604 drives the second connecting gear 605, the third connecting gear 607, and the fourth connecting gear 609 to rotate. The third connecting gear 607 and the fourth connecting gear 609 rotate in the same direction. The rotation of the third connecting gear 607 and the fourth connecting gear 609 drives the solid cross rod 610 and the hollow C-shaped rod 611 on both sides to rotate. This causes the metal connecting plate 303a and the first flipping plate 301 to drive the second flipping plate 302 to rotate along with the first transmission shaft 303b and the second transmission shaft 303d, thus achieving the purpose of rotating the welded parts.

[0076] During the welding process, non-sealed waste is generated. By starting the internal motor, the rotating rod 503 is rotated, which in turn drives the purification fan blades 504 on the surface to rotate, causing the waste to enter the ash storage box 501. At the same time, the worm gear 505 is rotated through the transmission shaft, causing the coolant inside the liquid storage tank 405 to flow. The coolant circulates and cools through the liquid pipe 402, the cooling heat pipe 404, and the liquid outlet pipe 403, preventing the weld joint from being cracked and damaged due to continuous high temperature. The cooling mechanism 400 is also controlled. When welding is in progress, the welded part will press down on the liquid control plate 406a below, causing it to move through the support spring 406e. The liquid control slider 406b and the pipe plug 406c move synchronously to open the channels of the liquid inlet pipe 402 and the liquid outlet pipe 403, allowing flow. When the welding is finished and the welded part is removed, the support spring 406e automatically resets and blocks the flow hole to prevent leakage when not in operation and unnecessary consumption of coolant.

[0077] In summary, when the support mechanism 100 is started, it drives the fixing mechanism 200 to fix it, avoiding the synchronization problem that occurs when the fixing mechanism 200 is driven by multiple driving devices. The flipping mechanism 300 is used to flip the welding point, which avoids the inability to adjust the position of the welding point in time during the welding work. When the suction mechanism 500 is used, it can drive the cooling mechanism 400 to work, which can absorb waste and prevent the welding joint from cracking and being damaged due to continuous high temperature.
