Description

Technical Field

[0001] The invention belongs to the technical field of wear-resistant plate welding, and in particular relates to a composite wear-resistant plate welding tool. Background Art

[0002] Composite wear-resistant plate, namely bimetallic composite wear-resistant steel plate, is a plate product specially designed for large-area wear conditions. It is an alloy wear-resistant layer formed by surfacing welding on ordinary steel plate, heat-resistant steel plate or stainless steel plate, with a volume fraction of more than 50% Cr7C3 carbide as the main component. Wear-resistant steel plate has high wear resistance, impact resistance, deformability and weldability. It can be directly processed like steel plate by curling, cutting and punching, and processed into engineering parts to meet wear conditions and put into use.

[0003] During welding, the weld area is rapidly heated and expanded, while the surrounding cooler areas restrict this expansion, which generates compressive stress; during cooling, the weld area contracts and is constrained by the surrounding areas, which in turn generates tensile stress. When these stresses exceed the yield strength of the workpiece material, the workpiece will deform. There are many types of deformation, such as shrinkage deformation, which reduces the size of the workpiece; angular deformation, which changes the plane angle of the workpiece; and wave deformation, which causes the surface of the workpiece to be wavy.

[0004] The present invention designs a composite wear-resistant plate welding tool to solve the above problems. Summary of the invention

Fig.13 As shown, the lower end of the mounting shell 503 is provided with a pressure plate outlet 515; Fig.15 , 16 As shown, a plurality of pressure plates 502 are connected end to end through uniformly arranged connecting members 508 and are uniformly slidably installed from top to bottom in the mounting shell 503; a second motor 504 is fixedly installed on the mounting shell 503, and the second motor 504 can control the pressure plates 502 to slide up and down in the mounting shell 503; Figure 8 , 10 As shown in FIG. 11 , an elastic bag 509 is fixedly mounted on each pressure plate 502, and a second water inlet 510 connected to the inside of the elastic bag 509 is opened at both ends of the pressure plate 502; Figure 5 , 6 As shown in , 7, the guide roller 501 is a hexagonal roller, and the guide roller 501 is rotatably mounted on the fixed plate 201; Figure 1 , 2As shown in FIG. 8 , two water tanks 505 are symmetrically installed on the upper side of the support base plate 1, and a first water inlet 507 is opened on the upper side of the water tank 505; Figure 5 , 8 As shown, the pressure plate 502 installed in the mounting shell 503 can be pulled out, and the pulled-out pressure plate 502 can be fixed on the upper side of the two water tanks 505 after bypassing the guide roller 501. When the pressure plate 502 and the water tank 505 are fixed, the first water outlet 507 on the water tank 505 and the corresponding second water outlet 510 on the pressure plate 502 are connected.

[0043] During welding, the composite wear-resistant plate 6 is placed on the supporting base plate 1, and the two ends of the composite wear-resistant plate 6 are fixed by external auxiliary tools; then the pressure plate 502 in the mounting shell 503 is pulled outward, so that its head passes over the guide roller 501 and is fixed to the front end of the two water tanks 505; when the pressure plate 502 is pulled onto the water tank 505, the elastic bag 509 originally located on the lower side of the pressure plate 502 is guided by the guide roller 501 and rotates to the upper side of the pressure plate 502. At this time, the first water inlet between the water tank 505 and the pressure plate 502 507 and the second water inlet 510 will be connected, and the water in the water tank 505 can flow into the elastic bag 509 installed on the pressure plate 502. By filling water into the elastic bag 509, the weight of the upper side of the pressure plate 502 can be increased. The pressure plate 502 and the elastic bag 509 filled with water can apply pressure to the upper side of the composite wear-resistant plate 6 to increase the fixing effect of the composite wear-resistant plate 6. At the same time, the water poured into the elastic bag 509 can cool the composite wear-resistant plate 6 after welding, thereby preventing the composite wear-resistant plate 6 from being deformed due to uneven local heating.

[0044] In the present invention, the elastic bag 509 can shrink under the action of its own elastic force before filling with water or after draining water; after being recovered into the installation shell 503, it does not need to occupy a large space. In addition, when the elastic bag 509 is pulled through the guide roller 501, it is in a contracted state and can pass through the guide roller 501 smoothly without affecting the normal operation of the guide roller 501.

[0045] In a further embodiment, Figure 3 , 4As shown, two traveling brackets 205 are fixedly installed on the lower sides of both ends of the fixed plate 201, and two traveling wheels 204 are rotatably installed on the two traveling brackets 205; a transmission assembly 203 is installed on the fixed plate 201, and the output shaft of the first motor 202 and the rotating shaft of one of the two traveling wheels 204 are connected by transmission through the transmission assembly 203. When the first motor 202 is controlled to work, the first motor 202 will drive the corresponding traveling wheel 204 to rotate, and the rotation of the traveling wheel 204 will drive the fixed plate 201 to move relative to the supporting bottom plate 1; the movement of the fixed plate 201 drives the welding device 3 and the guide roller 501 installed thereon to move, and the movement of the welding device 3 can realize welding feeding.

[0046] In the present invention, since the pulled out pressure plate 502 will be fixed on the water tank 505 after passing around the guide roller 501, the pressure plate 502 at the starting end is fixed, so when the guide roller 501 is driven to move toward the side away from the mounting shell 503, the guide roller 501 will pull the pressure plate 502 in the mounting shell 503 to slide outward, so as to realize the function of successively pulling out the pressure plate 502 in the mounting shell 503 and attaching it to the upper side of the composite wear-resistant plate 6 welded on the two water tanks 505; when the pressure plate 502 is pulled onto the water tank 505, the elastic bag 509 originally located at the lower side of the pressure plate 502 will rotate to the pressure plate 505 after being guided by the guide roller 501. 02 upper side, at this time, the first water inlet 507 and the second water inlet 510 between the water tank 505 and the pressure plate 502 will be connected, and water will be filled into the water tank 505. The water in the water tank 505 can flow into the elastic bag 509 installed on the pressure plate 502. By filling water into the elastic bag 509, the weight of the upper side of the pressure plate 502 can be increased, and the pressure plate 502 and the elastic bag 509 after filling with water can be used to apply pressure on the upper side of the composite wear-resistant plate 6 to increase the fixing effect of the composite wear-resistant plate 6. At the same time, the water poured into the elastic bag 509 can cool down the composite wear-resistant plate 6 after welding, thereby preventing the composite wear-resistant plate 6 from deforming due to uneven local heating.

[0047] In a further embodiment, Figure 8 , 9 As shown, the pressure plate 502 is a metal plate, and a plurality of magnetic blocks 506 are evenly fixedly installed on the upper side of the water tank 505; when the pressure plate 502 falls on the upper side of the water tank 505, the pressure plate 502 will be adsorbed and fixed by the magnetic blocks 506, and at this time, the first water outlet 507 on the water tank 505 and the second water outlet 510 on the pressure plate 502 are aligned with each other.

[0048] In a further embodiment, Figure 3 As shown, a plurality of support strips 4 are evenly laid on the upper side of the support base plate 1 .

[0049] In a further embodiment, Fig.13 ,14 As shown in FIG. 15 , two transmission wheels 513 are respectively installed on both sides of the mounting shell 503, and the two transmission wheels 513 on the same side are connected by a transmission belt 512; two second motors 504 are fixedly installed on the mounting shell 503, and the output shafts of the two second motors 504 correspond to the rotating shafts of the two transmission wheels 513 on the upper side and are connected to each other; Fig.17 , 18 As shown, a plurality of shifting plates 514 are evenly fixedly installed on the conveyor belt 512; the shifting plates 514 cooperate with the pressure plates 502 installed in the mounting shell 503; Fig.12 , 13 As shown, a plurality of electric push rods 511 are evenly and fixedly installed in the installation shell 503 , and the electric push rods 511 are located at the lower side of the pressure plate 502 .

[0050] When the second motor 504 is controlled to work, the second motor 504 will drive the corresponding transmission wheel 513 to rotate, and the rotation of the transmission wheel 513 drives the transmission belt 512 to rotate, and the rotation of the transmission belt 512 drives the dial plate 514 to slide; in the present invention, when the pressure plate 502 is located in the mounting shell 503 and cooperates with the dial plate 514 on the transmission belt 512, the pressure plate 502 corresponds to the dial plate 514 at the same height, that is, one layer of dial plate 514 corresponds to one pressure plate 502; when the pressure plate 502 is pulled out, the second motor 504 is controlled to work so that the side of the transmission belt 512 close to the pressure plate 502 slides downward to ensure that the pressure plate 502 can be pulled out smoothly; when the pressure plate 502 is used up, the water in the water tank 505 is released, and the water in the elastic capsule 509 will flow back into the water tank 505. When the water in all the used elastic capsules 509 is completely released, the second motor 504 is controlled. When the cam 512 is in operation, the second motor 504 drives the corresponding transmission wheel 513 to rotate. The rotation of the transmission wheel 513 drives the transmission belt 512 to rotate. The rotation of the transmission belt 512 drives the side close to the pressure plate 502 to slide upward. The paddle plate 514 drives the corresponding pressure plate 502 to slide upward. The pressure plate 502 in the mounting shell 503 pulls the pressure plate 502 outside the mounting shell 503 through the connecting piece 508, so that it moves one by one into the mounting shell 503. The pressure plate 502 moved into the mounting shell 503 will be pushed upward by the electric push rod 511 to move upward and cooperate with the corresponding paddle plate 514. In the present invention, a sensor is installed on the upper end of the electric push rod 511. The sensor can be used to determine whether the pressure plate 502 is suitable for pushing upward and whether it can cooperate with the corresponding paddle plate 514 after pushing upward. Only when both are met, the electric push rod 511 will push the pressure plate 502 upward.

To make the description concise, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.
