Description

Technical Field

[0001] The invention relates to the technical field of welding, and in particular to a stainless steel-carbon steel composite plate assembly welding device. Background Art

[0002] Stainless steel-carbon steel composite plate assembly is a composite material plate formed by combining two different materials, stainless steel and carbon steel, through a welding process. Such a composite plate usually has the advantages of two different materials and is used in application scenarios that require a combination of the characteristics of these two materials.

[0003] During the lifting of stainless steel-carbon steel composite plate groups, it is usually necessary to lift two different slabs onto a welding platform. For example, a stainless steel-carbon steel composite plate assembly welding device disclosed in publication number CN109014515B, however, during the lifting of the stainless steel-carbon steel composite plate group, since the stainless steel and carbon steel slabs have different physical properties and hardness, if the slabs are not effectively fixed and protected, collision and bending between the slabs may occur. In particular, during the lifting process, the fixing method of the traction rope and the contact point of the slabs are prone to uneven force. This bending phenomenon occurs on the slabs. The welding end of the billet is particularly obvious and may affect the subsequent welding quality. Specifically, when lifting, the billet may collide with each other due to uneven tension or excessive swing of the traction rope, which may cause local bending of the billet at the contact point (especially the welding end). The bending of the billet may not only affect its positioning accuracy, but also make the welding seam uneven, resulting in an uneven welding surface, which in turn affects the welding quality and strength. When overlapping the composite plate, if the welding end is bent too much, the weld may be too wide or asymmetrical, resulting in insufficient welding strength or unreliable welding, and the ideal welding effect cannot be achieved. Summary of the invention

[0004] In view of the above-mentioned shortcomings of the prior art, the present invention provides a stainless steel-carbon steel composite plate assembly welding device, which can effectively solve the problem in the prior art that during the lifting process of the stainless steel-carbon steel composite plate groups, collisions or local bending of the contact points caused by the tension of the traction rope may cause the weld to be too wide or asymmetric during subsequent welding.

At the same time, if the curvature of the slab is too large or too small, it will drive the rotating disk to rotate different numbers of times. When the curvature of the slab is too large, the sliding frame that the permanent magnetic hammer block is driven to hit drives the sliding frame to hit the curved part of the slab more frequently, thereby repairing the slab with a relatively large curvature through a relatively large number of impacts. When the curvature of the slab is small, the sliding frame that the permanent magnetic hammer block is driven to hit drives the sliding frame to hit the curved part of the slab less frequently, thereby repairing the slab with a relatively small curvature. In this way, slabs with different curvatures can be repaired, and excessive or insufficient repair can be effectively avoided. BRIEF DESCRIPTION OF THE DRAWINGS

The baffle 432 is slidably connected with the second screw sleeve 431. An oblique slot is provided on one side of the baffle 432.

At this time, the solenoid valve 442 is closed to prevent the gas from flowing, thereby affecting the movement of the slide plate 443. When the extrusion rod 437 contacts the slide plate 443, the slide plate 443 cannot be driven to move, and the slide plate 443 will slide in the block 436 due to resistance.

[0028] Reference Figures 8 to 10 , and also includes a clamping assembly 5, which includes two long plates 501 fixedly installed at the bottom end of the welding box 1, and two pairs of threaded columns 502 are installed with internal threads of the long plates 501, and each pair of threaded columns 502 is rotatably installed with a clamping plate 503 relative to one end.

[0029] The working principle of the present invention is as follows: The stainless steel-carbon steel composite plate assembly (hereinafter referred to as the plate) is placed on the inner bottom end of the welding box 1, and the threaded column 502 is twisted to drive the clamping plate 503 to move relatively to clamp and fix the plate (in this process, welding materials are added to fill the weld between the plate blanks as a transition layer to effectively reduce the thermal expansion difference between the two materials). The moving head 401 is driven to move by driving the linear drive device 2. When the moving head 401 moves, it will drive the vertical rod 402, the U-shaped frame 403 and the bearing plate 404 to move together. When the bearing plate 404 moves, it will drive the moving plate 407 and the contact wheel 408 to move together. The moving plate 407 and the contact wheel 408 will move on the plate blank. When one of the slabs has a bent portion, the bent portion will contact the contact wheel 408 and drive the moving plate 407 and the screw 409 to move. The moving moving plate 407 will slide on the outer wall of the first slide bar 405 and compress the first spring 406. When moving, the screw 409 will be threadedly connected with the first screw sleeve 411 and drive the first screw sleeve 411 to rotate (the screw 409 and the first screw sleeve 411 are non-self-locking threaded connection). The rotating first screw sleeve 411 will drive the rotating disk 412 to rotate, and the rotating rotating disk 412 will drive the staggered negative electrical contacts 413 to contact the connector 415 in turn (the negative electrical contacts 413 are connected to the connector 415 in turn). The positive contacts are distributed as positive contact → negative contact → positive contact → negative contact, and are arranged in a circle on the rotating disk 412. When one of the positive contacts contacts the connector 415 and is energized, the other connector 415 is connected to the negative contact and energized. The energized connector 415 transmits the current to the conductive block, and the conductive block transmits the current to the electromagnetic field regulator by sliding with the connecting contact 418. The electromagnetic field regulator then transmits the current to the electromagnet, causing the electromagnet to generate magnetism (when the connector 415 continuously switches the positive and negative poles with the negative contact 413 to be energized, the current transmitted to the electromagnet will change the magnetic pole of the electromagnet, and the magnetic pole of the electromagnet will The electromagnet will attract the permanent magnetic hammer block 430 to slide in the installation barrel 426 while continuously converting the magnetic pole. The north pole of the magnetic pole will attract the permanent magnetic hammer block 430 to approach the electromagnet and compress the fourth spring 429. The south pole of the magnetic pole will repel the permanent magnetic hammer block 430 and the repulsive force generated in conjunction with the compressed fourth spring 429 will push the permanent magnetic hammer block 430 to hit the sliding frame 423. The hit sliding frame 423 will slide in the sliding box 420 to stretch the third spring 422 and drive the extrusion plate 424 to hit the bending part of the slab to repair the slab. At the same time, the coil 427 after the current flow direction is changed will make the alarm device sound an alarm. It should be noted that, in the process of connecting the electric contact 418 to transmit current to the coil 427 to make the iron core generate magnetism, the positive and negative poles of the connected power supply are constantly changing, causing the magnetic poles of the electromagnet to change continuously. In the process of the positive and negative poles of the electromagnet constantly changing, the electromagnetic field regulator can adjust the flow of current in real time, steadily control the intensity and direction of the magnetic field, and thus reduce the instability of magnetic force conversion. At the same time, if the curvature of the slab is too large or too small, it will drive the rotating disk 412 to rotate at different numbers. When the curvature of the slab is relatively large, the number of rotations of the rotating disk 412 per unit time is relatively large, and the positive and negative poles of the negative electric contact 413 are in contact with the connector 415. At the same time, the frequency of continuously switching the current flow direction increases, and the switching of the positive and negative poles of the magnetism generated by the electromagnet will also increase, and the sliding frame 423 driven to hit the permanent magnetic hammer block 430 drives the sliding frame 423 to hit the bending part of the slab more frequently, so that the slab with a relatively large curvature can be repaired through a relatively large number of impacts. In summary, when the curvature of the slab is small, the sliding frame 423 driven to hit the permanent magnetic hammer block 430 drives the sliding frame 423 to hit the bending part of the slab less frequently, so as to repair the slab with a relatively small curvature. In this way, slabs with different curvatures can be repaired, and over-repair or under-repair can be effectively avoided. For slabs of different thicknesses, a plugging plate is added between the moving plate 407 and the carrying plate 404 in advance to increase the distance between the moving plates 407 so as to adapt to the width between the slabs. When repairing the curvature of the slab, the slab is repaired by reciprocatingly driving the repairing assembly 4. When the slab is not bent and the current flow direction input to the coil 427 is not changed so that the alarm stops, it can be determined that the slab repair is completed. After the repair of the slab is completed, the repair component 4 is driven to return to its original position by the linear drive device 2, and the solenoid valve 442 is controlled by the controller to be closed, so that the air in the buffer box 441 cannot be discharged to the outside to form a closed space. After the moving head 401 is driven to the original position, the extrusion rod 437 will contact the slide plate 443, and the slide plate 443 cannot move in the buffer box 441 because the solenoid valve 442 is closed. The extrusion rod 437 is resisted by the slide plate 443 and slides in the block 436. The linkage block 438 compresses the sixth spring 440, and the sliding of the extrusion rod 437 in the block 436 drives the extrusion block 439 to contact the inclined groove. The baffle plate 432 is squeezed to slide in the inner groove and disengage from the second screw sleeve 431, and the second partition plate 434 compresses the fifth spring 435. By opening the screw clutch, the linear drive device 2 drives the moving frame 301 to move, and the moving frame 301 drives the carrying frame 302, the welding machine 303 and the welding head 304 to move. When the linear drive device 2 is driven, the driving screw in the linear drive device 2 drives the second screw sleeve 431 to rotate, and the second screw sleeve 431 is not limited by the baffle plate 432 at this time and can only rotate in the empty groove and cannot drive the moving head 401 to move. During the movement of the carrying frame 302, the external plate 3 05 and the straight plate 306 move, the straight plate 306 will be slidably connected with the inner wall of the adapter box 416, the straight plate 306 will squeeze the slider 417 and compress the second spring 419, and the conductive head 307 will slide and contact with the connecting electrical contact 418 provided in the adapter box 416 to energize, the straight plate 306 pushes the adapter box 416 to move, and the adapter box 416 drives the repair component 4 to move, after the repair component 4 moves, the compressed sixth spring 440 will drive the extrusion rod 437 and the extrusion block 439 to return to the square groove, and the compressed fifth spring 435 will be slidably connected with the second screw sleeve 431 again, and the linear drive device 2 drives the welding component 3 to move During the movement, the repair component 4 is also driven synchronously, and the conductive head 307 replaces the conductive block to energize the connecting electric contact 418. During the process of the welding component 3 and the repair component 4 being synchronously driven by the linear drive device 2 to move, the welding component 3 welds the welds between the slabs through the welding head 304. During the process of the conductive head 307 replacing the conductive block to energize the connecting electric contact 418, the magnetic force generated by the electromagnet will always repel the permanent magnet hammer block 430, allowing the permanent magnet hammer block 430 to squeeze the sliding frame 423 and the extrusion plate 424 to squeeze the slab, so that the slabs become tight with the filling material, so that after welding, the slabs will become tighter.
