Description

Technical Field

[0001] The invention relates to the technical field of hardware welding, and in particular to a plasma arc welding machine for hardware products and a method thereof. Background Art

[0002] Plasma arc is a high-temperature ion gas flow produced by ion gas being ionized, which is ejected from the nozzle hole and compressed to form a slender arc column. Plasma arc has the characteristics of slender arc column and high energy density. It is widely used in the field of welding. As a welding device, the metal products to be welded need to be fixed during the welding preparation process, and then the welding position is adjusted to ensure the accuracy of the welding position. After welding is completed, the welding power is turned off and wait for cooling.

[0003] However, during the welding preparation process, the welding position cannot be adjusted while the welding is fixed. The welding equipment is too heavy and it is too troublesome to adjust its position. At the same time, the metal products cannot be rotated or flipped during the welding process, and manual processing is usually required. Since the temperature of the equipment is high during the welding process, the operator is easily injured. The natural cooling during the welding work is relatively slow, and the welding joints are prone to cracks and damage, which affects the service life of the equipment. Summary of the invention

[0031] In order to make the above-mentioned objects, features and advantages of the present invention more obvious and easy to understand, the specific implementation methods of the present invention are described in detail below in conjunction with the accompanying drawings.

[0032] In the following description, many specific details are set forth to facilitate a full understanding of the present invention, but the present invention may also be implemented in other ways different from those described herein, and those skilled in the art may make similar generalizations without violating the connotation of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.

[0033] Secondly, the term "one embodiment" or "embodiment" as used herein refers to a specific feature, structure, or characteristic that may be included in at least one implementation of the present invention. The term "in one embodiment" that appears in different places in this specification does not necessarily refer to the same embodiment, nor does it refer to a separate or selective embodiment that is mutually exclusive with other embodiments.

[0034] Secondly, the present invention is described in detail with reference to the schematic diagram. When describing the embodiments of the present invention in detail, for the sake of convenience, the cross-sectional diagrams showing the device structure will not be partially enlarged according to the general scale, and the schematic diagrams are only examples, which should not limit the scope of protection of the present invention. In addition, in actual production, the three-dimensional dimensions of length, width and depth should be included.

[0035] Reference Figures 1 to 10 , which is the first embodiment of the present invention, provides a plasma arc welding method for hardware products. Through the plasma arc welding machine for hardware products and the method thereof, the effects of flipping adjustment, welding joint cooling and cooling liquid control are achieved.

[0036] When the support mechanism 100 is started, it drives the fixing mechanism 200 to fix, avoiding the synchronization problem of the fixing mechanism 200 through multiple driving devices, achieving smooth start and operation, and at the same time, it can also drive the flipping mechanism 300 to flip, ensuring that the workpiece is firmly fixed in the predetermined position during the welding process. When the support mechanism 100 is started, the power is transmitted to the fixing mechanism 200 through the transmission device, so that the clamping device moves quickly to fix the workpiece; When the air suction mechanism 500 is started, the cooling mechanism 400 can be driven to work. The air suction mechanism 500 sucks in the smoke generated during the welding process through the pipeline and collects it to avoid directly throwing harmful gases into the environment to reduce environmental pollution. The cooling mechanism 400 prevents the welding port from being cracked and damaged due to continuous high temperature. The cooling mechanism 400 can be controlled by using the liquid control component 406. When the cooling mechanism 400 does not need to work, the liquid control component 406 can automatically shut off the supply to avoid leakage.

[0037] Reference Figures 5 to 9 , which is a second embodiment of the present invention, provides a flipping mechanism 300, through which the rotation adjustment of the welding part is achieved.

[0038] The flip mechanism 300 includes a first flip plate 301, the bottom of the first flip 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 the second flip plate 302, the right side of the first flip plate 301 is fixedly connected to the transmission assembly 303, the bottom of the plasma arc welding device 105 is fixedly connected to the cooling mechanism 400, the front end of the support block 103 is fixedly connected to the suction mechanism 500, and the top of the processing table 102 is fixedly connected to the linkage mechanism 600.

[0039] The linkage mechanism 600 includes a cushion block 601, the top of the cushion block 601 is fixedly connected to a U-shaped plate 602, the inner cavity of the U-shaped plate 602 is movably connected to a movable rod 603, the top and bottom of the movable rod 603 both penetrate the inner wall and bottom of the U-shaped plate 602, the top of the movable rod 603 is fixedly connected to a first linkage gear 604, the bottom of the inner wall of the U-shaped plate 602 and corresponding to the left side of the first linkage gear 604 is movably connected to a second linkage gear 605 through a rotating shaft, the left side of the inner cavity of the U-shaped plate 602 is movably connected to a first rotating column 606, the right side of the first rotating column 606 penetrates the inner wall of the U-shaped plate 602 and is fixedly connected to a third linkage gear 607, and the right side of the inner cavity of the U-shaped plate 602 is movably connected to the first linkage gear 605. The second rotating column 608 is dynamically connected, and the left side of the second rotating column 608 passes through the inner wall of the U-shaped plate 602 and is fixedly connected with the fourth connecting gear 609. 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. The left side of the first rotating column 606 and the right side of the second rotating column 608 pass through the left and right sides of the U-shaped plate 602 and are fixedly connected with a cross solid rod 610. The top of the cross solid rod 610 is slidably connected with a C-shaped hollow rod 611, and the right side of the C-shaped hollow rod 611 is fixedly connected to the left side of the transmission assembly 303.

[0040] 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 flip plate 301, the right side of the metal connecting plate 303a is movably connected to the first transmission shaft 303b through a rotating shaft, the right side of the first transmission shaft 303b is movably connected to the metal support plate 303c through 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 through 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, and the second transmission shaft and the first transmission shaft 303b are connected through track transmission.

[0041] The gear assembly 202g includes a first circular plate 202g-1, the top of the first circular plate 202g-1 and the top of the inner wall of the processing table 102 are movably connected via a rotating shaft, the bottom of the first circular plate 202g-1 is fixedly connected to a second interlocking gear 202g-2, the bottom of the movable rod 603 is fixedly connected to a second circular plate 202g-3, and the second circular plate 202g-3 and the first circular plate 202g-1 are connected via a crawler drive.

[0042] 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, which greatly improves the flexibility of welding and can adapt to the welding requirements of workpieces of various complex shapes.

[0043] Specifically, the first interlocking gear 604, the second interlocking gear 605, the third interlocking gear 607 and the fourth interlocking gear 609 mesh with each other to form a stable and precise transmission system. This multi-gear design can ensure the accuracy of the transmission ratio, so that the third interlocking gear 607 and the fourth interlocking gear 609 rotate in the same direction.

[0044] 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 flip plate 301 to achieve control of the flip angle.

[0045] 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 via a rotating shaft, and the second circular plate 202g-3 and the first circular plate 202g-1 are connected via a crawler drive, and can work in conjunction with the fixing mechanism 200, the flipping mechanism 300 and the linkage mechanism 600.

[0046] Furthermore, the workpieces to be welded are placed on the first flip plate 301 and the second flip plate 302 and fixed by the fixing mechanism 200 , and then the first flip plate 301 and the second flip plate 302 that are movably connected can be rotated and adjusted.

[0047] 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, and 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 cross solid rod 610 and the C-shaped hollow rod 611 on both sides to rotate to meet the adjustment requirements of the welding point position during the welding process.

[0048] 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, the first transmission shaft 303b is driven to rotate through the crawler, which transmits power to the first flip plate 301 through the metal connecting plate 303a, thereby realizing the control of flip adjustment.

[0049] Furthermore, the first control gear 202f meshes with the second interlocking gear 202g-2, thereby driving the second interlocking gear 202g-2 to rotate. The rotation of the second interlocking gear 202g-2 drives the first circular plate 202g-1 to rotate and drives the second circular plate 202g-3 through the transmission track, so that the flip adjustment components can be connected to realize the rotation adjustment of the weldment during welding work.

[0050] Reference Figure 3 and 4 , which is the third embodiment of the present invention, provides a cooling mechanism 400, through which the cooling mechanism 400 can achieve the effect of rapid cooling of the welding joint.

[0051] The cooling mechanism 400 includes a fixed block 401, the top of the fixed block 401 is fixedly connected to the bottom of the plasma arc welding device 105, the inner cavity of the fixed block 401 is provided with a liquid inlet pipe 402 and a liquid outlet pipe 403, and the liquid inlet pipe 402 is arranged on the left side of the liquid outlet pipe 403, the front end of the liquid inlet pipe 402 is fixedly connected with a cooling heat pipe 404, a section of the cooling heat pipe 404 away from the liquid inlet pipe 402 is fixed to the front end of the liquid outlet pipe 403, the cooling heat pipe 404 is arranged on the top of the surface of the welding nozzle 106, a liquid storage tank 405 is provided at the bottom of the liquid inlet pipe 402 and the liquid outlet pipe 403, the back end of the liquid storage tank 405 is fixedly connected to the front end of the support block 103, and the inner cavity of the liquid storage tank 405 is provided with a liquid control component 406.

[0052] The liquid control assembly 406 includes a liquid control plate 406a, which is arranged in the inner cavity of the liquid storage tank 405. The back end of the liquid control plate 406a is fixedly connected to a liquid control slider 406b, and the left and right sides of the top of the liquid control slider 406b and the positions corresponding to the liquid inlet pipe 402 and the liquid outlet pipe 403 are fixedly connected to pipe plugs 406c, and the left and right sides of the bottom of the liquid control plate 406a are fixedly connected to a first spring block 406d, the bottom of the first spring block 406d is fixedly connected to a support spring 406e, the bottom of the support spring 406e is fixedly connected to a second spring block 406f, and the bottom of the second spring block 406f is fixedly connected to the top of the processing table 102.

[0053] Specifically, the liquid inlet pipe 402 is responsible for introducing the coolant into the cooling heat pipe 404, and the liquid outlet pipe returns the coolant that has absorbed the heat to the liquid storage tank 405, forming a circulating flow, achieving 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.

[0054] Specifically, it can be adjusted according to welding, and the liquid inlet pipe 402 and the liquid outlet pipe 403 are controlled by the liquid control plate 406a. When the liquid control plate 406a is in a pressed state, the liquid inlet pipe 402 and the liquid outlet pipe 403 can circulate to cool the welding nozzle 106.

[0055] Furthermore, the coolant flows from the liquid storage tank 405 into the cooling heat pipe 404 through the liquid inlet pipe 402. Since the cooling heat pipe 404 is arranged 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 flows back to the liquid storage tank 405 through the liquid outlet pipe 403, ensuring that the welding nozzle will not be cracked or damaged.

[0056] Furthermore, the welding part will press the liquid control plate 406a below to make the liquid control slider 406b and the pipe plug 406c move synchronously, open the channels of the liquid inlet pipe 402 and the liquid outlet pipe 403, and allow them to flow. When the welding work is completed, the welding part is removed and the flow hole is automatically reset by the support spring 406e to avoid leakage when not working, which causes unnecessary consumption of coolant.

[0057] The remaining structure is the same as that of Example 2.

[0058] Reference Figures 1 to 10 , which is the fourth embodiment of the present invention. This embodiment is different from the third embodiment in that: this embodiment provides a plasma arc welding machine for hardware products.

[0059] When preparing for welding, the metal product to be welded is placed in the first flip plate 301, and then the elevator 104 is started to drive the plasma arc welding device 105, the welding nozzle 106, the cooling mechanism 400, the solid plate 210, the hollow plate 211, the second C-shaped plate 212 and the second flip plate 302 to move downward synchronously to fix the welded parts.

[0060] The transmission motor 202a is started to drive 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 at the same time drives the second control gear 202h and the first interlocking gear 202i to rotate. The rotation of the first interlocking gear 202i drives the first tooth plate 205 and the second tooth plate 206 to move towards each other, and at the same time drives the connecting plate 207, the connecting block 208, the first C-type plate 209, the second C-type plate, the first flip plate 301, the second flip plate 302, the metal connecting plate 303a, the first transmission shaft 303b, the metal support plate 303c, the second transmission shaft 303d and the C-type hollow rod 611 to move through the cross solid rod 610, so that the left and right welding parts are clamped toward the middle to avoid large welds during welding.

[0061] When the welded part needs to be rotated, the transmission motor 202a is moved upward a short distance through the small cylinder 201, so that the second control gear 202h and the first interlocking gear 202i are disengaged, and at the same time, the first control gear 202f is moved upward to engage with the second interlocking gear 202g-2, thereby driving the second interlocking gear 202g-2 to rotate. The rotation of the second interlocking gear 202g-2 drives the first circular plate 202g-1 to rotate, and drives the second circular plate 202g-3, the movable rod 603 and the first linkage gear 604 to rotate through the transmission track. The first gear 604 rotates to drive the second connecting gear 605, the third connecting gear 607 and the fourth connecting gear 609 to rotate, and 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 cross solid rod 610 and the C-shaped hollow rod 611 on both sides to rotate, and makes the metal connecting plate 303a and the first flip plate 301 drive the second flip plate 302 to follow the rotation through the first transmission shaft 303b and the second transmission shaft 303d, so as to achieve the purpose of rotating the welded parts.

[0062] During the welding process, unsealed waste will be generated. By starting the internal motor to drive the rotating rod 503 to rotate, the rotating rod 503 will drive the purification fan blades 504 set on the surface to rotate so that the waste enters the ash storage box 501. At the same time, the turbine rod 505 is driven by the transmission shaft to rotate and drive the coolant inside the liquid storage tank 405 to flow. The coolant is circulated and cooled through the liquid pipe 402, the cooling heat pipe 404 and the liquid outlet pipe 403 to avoid continuous high temperature at the welding port, which is prone to cracks and damage. The cooling mechanism 400 will be controlled at the same time. When the welding work is in progress, the welding part will press the liquid control plate 406a below to move it 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, so that the waste can flow. When the welding work is completed, the welding part is removed, and the support spring 406e automatically resets to block the flow hole to avoid leakage when not working, resulting in unnecessary consumption of coolant.

[0063] In summary, when the support mechanism 100 is started, it drives the fixing mechanism 200 to fix, thereby avoiding the synchronization problem caused by the fixing mechanism 200 through multiple driving devices. The flipping mechanism 300 is used for flipping, thereby avoiding 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, absorb the waste and avoid the continuous high temperature at the welding port, which is prone to cracks and damage.
