Description

Technical Field

[0001] The present invention relates to the technical field of plasma welding, and particularly relates to a plasma welding device for additive surfacing on the surface of an automotive mold. Background Art

[0002] Performing plasma surfacing additive on the surface of an automotive mold can achieve the repair and strengthening of the surface of the automotive mold. It mainly uses the plasma arc as a heat source to quickly heat the alloy powder and the surface of the automotive mold to a molten state, and then mix, diffuse, react, and solidify. While moving with the plasma beam, it self-excites and cools to form a high-hardness metal layer on the mold surface. In the prior art, when performing plasma surfacing additive on the surface of an automotive mold, it is usually manually operated, with low efficiency, large workload, and it may also cause harm to the operator when operated improperly.

[0038] When the position adjustment component is working: the output shaft of the motor four 602 drives the lead screw three 603 to rotate. When the lead screw three 603 rotates, it drives the sliding carriage 601 to move. When the sliding carriage 601 moves, it drives the material injection component and the fixed frame two 606 to move, and the fixed frame two 606 drives the slider two 607 to move; the output shaft of the motor five 605 drives the lead screw four 608 to rotate.

When the slider two 607 moves, it drives the angle adjustment component and the cleaning component to move, and the angle adjustment component drives the plasma welding torch 301, so that the position of the slider two 607 in two directions can be changed.

[0039] When the first angle adjustment unit is working: the output shaft of the motor one 306 drives the lead screw one 326 to rotate. When the lead screw one 326 rotates, it drives the slide base one 305 to move. When the slide base one 305 moves, it drives the gear one 314 to rotate through the rack 313.

[0042] When the trajectory adjustment mechanism is working: the output shaft of the motor three 402 drives the lead screw two 404 to rotate. When the lead screw two 404 rotates, it drives the lifting frame 407 to move. The lifting frame 407 drives the electric cylinder 401 to move through the support block four 406. When the moving trajectory of the plasma welding torch 301 needs to be arc-shaped, the electric cylinder 401 in a set of trajectory adjustment mechanisms drives the track plate one 408 to lift, and the piston rod of the electric cylinder 401 drives the track plate one 408 to move horizontally. When the moving trajectory of the plasma welding torch 301 needs to be parallel, the electric cylinder 401 in another set of trajectory adjustment mechanisms drives the track plate two 409 to move, and the piston rod of the electric cylinder 401 drives the track plate two 409 to move horizontally.

[0043] When the support unit is working: When the movement trajectory of the plasma welding torch 301 needs to be an arc, the connecting frame 309 moves driven by the movement adjustment component. The connecting frame 309 drives the support rod 307 to move in the arc-shaped groove in the first track plate 408. When the support rod 307 moves, the second telescopic rod 311 slides in the first telescopic rod 310, and the second telescopic rod 311 is compressed or expanded, so that the plasma welding torch 301 moves along the trajectory of the arc-shaped groove; When the movement trajectory of the plasma welding torch 301 needs to be parallel, the connecting frame 309 moves driven by the movement adjustment component. The connecting frame 309 drives the support rod 307 to move in the straight groove of the second track plate 409, so that the plasma welding torch 301 moves along the trajectory of the straight groove.

[0044] When the cleaning component is working: The position adjustment component drives the second support plate 501 to move through the connecting frame 309. The second support plate 501 drives the blower 502 and the cleaning nozzle 503 to move. The cleaning liquid is sprayed through the cleaning nozzle 503, and the mold is dried by the blower 502.

[0045] The working principle of the present invention is as follows: Place the automotive mold to be welded on the first support plate 202. The piston rod of the hydraulic cylinder 201 drives the first support plate 202 to move. The first support plate 202 drives the automotive mold to move to the required position where the first support plate 202 moves. The driving wheel 102 drives the support frame 101 to move, and the surface of the automotive mold is cleaned by the cleaning component; After the cleaning is completed, the driving wheel 102 drives the support frame 101 back to the required position. Place an inductor corresponding to the sensor 303 at the position where the automotive mold needs to be welded. Adjust the angle of the plasma welding torch 301 through the first angle adjustment unit and the second angle adjustment unit. When the sensor 303 corresponds to the inductor, it means that the angle adjustment is completed. At this time, record the corresponding rotation angles respectively through the first pointer 318 and the second pointer 324, so as to facilitate plasma welding of the positions that need to be cladded and added on the surfaces of the same automotive molds in batches.

[0046] When the required welding trajectory is an arc trajectory, replace the first track plate 408 with the corresponding arc angle according to the trajectory. Drive the first track plate 408 to move through a set of trajectory adjustment mechanisms, so that the support rod 307 is inserted into the arc-shaped groove on the first track plate 408. Drive the second track plate 409 to move through another set of trajectory adjustment mechanisms, so that the second track plate 409 moves away from the support rod 307; When the required welding trajectory is a parallel trajectory, drive the second track plate 409 to move through a set of trajectory adjustment mechanisms, so that the support rod 307 is inserted into the straight groove on the second track plate 409. Drive the first track plate 408 to move through another set of trajectory adjustment mechanisms, so that the first track plate 408 moves away from the support rod 307.

[0047] Drive the support unit to move through the position adjustment component. The support unit drives the plasma welding torch 301 to move through the first angle adjustment unit and the second angle adjustment unit. Inject materials from the feeding tank 702, and separate the materials with larger sizes through the material distribution plate 704, which can prevent the problem of blocking the welding head due to larger sizes and also prevent the problem of affecting the welding effect due to larger sizes. The materials enter the plasma welding torch 301 through the injection pipe, and the surface of the automotive mold is subjected to cladding additive welding through the plasma welding torch 301.
