Technical Field
[0001] The present application relates to the technical field of steel plate welding supports, and in particular to a device for eliminating reverse deformation stress of steel plate welding. Background Art
[0002] Steel plate is a flat sheet of steel formed by pouring molten steel and pressing it after cooling. It is a flat, rectangular sheet that can be directly rolled or cut from wide steel strip. Steel plate is categorized by thickness as follows: thin plate <4 mm (the thinnest is 0.2 mm), medium-thick plate 4-60 mm, and extra-thick plate 60-115 mm. Steel plate is categorized by rolling process into hot-rolled and cold-rolled.
[0003] However, in actual applications, during the welding process of most existing steel plates, the high temperature will cause the welded steel plates to generate stress on the welding surface, causing the entire steel plate to bend and deform to varying degrees, thereby reducing the welding quality of the steel plates and increasing the defective rate, which is not conducive to their promotion and use.
[0004] Therefore, those skilled in the art have provided a device for eliminating the reverse deformation stress of steel plate welding to solve the problems raised in the above background technology. Utility Model Content

[0006] The device for eliminating the reverse deformation stress of steel plate welding provided in the present application adopts the following technical solution: it includes a bracket, and a plurality of support blocks are slidably connected to the inner walls of the front and rear sides of the bracket, and the top sides of the plurality of support blocks and the top side of the bracket are fixedly connected with an arc-shaped support plate, the left side of the bracket is fixedly connected to a motor, the output shaft of the motor is fixedly connected to a screw rod, and the plurality of support blocks are all spirally connected to the screw rod.
[0007] Preferably, two grooves are provided on the bottom sides of the plurality of support blocks, and circular rollers are rotatably mounted on the inner walls of the plurality of grooves, and the lowest points of the plurality of circular rollers are flush with the bottom side of the bracket.
[0008] Preferably, two guide rods are fixedly connected to the inner walls on the left and right sides of the bracket, and the two guide rods both pass through the multiple bracket blocks and form a sliding connection with each other.
[0009] Preferably, two clamping plates are fixedly connected to the left and right sides of the plurality of support blocks, and the plurality of clamping plates form a group of four, and each group of clamping plates contacts the left and right sides of the arc-shaped support plate respectively.
[0010] Preferably, a protective cover is fixedly connected to the left side of the bracket, and the motor is located inside the protective cover.
[0011] In summary, this application has the following beneficial technical effects:
[0012] 1. By setting up an arc-shaped support plate, the steel plate to be welded is placed on the top side of the bracket in contact with the arc-shaped support plate. At this time, due to the flexibility of the steel plate itself, it will be placed in an arc shape in contact with the surface of the arc-shaped support plate under the influence of its own weight. At this time, when welding, the steel plate in the bent state can just offset the stress generated by the high temperature during welding, ensuring that the steel plate remains flat after welding, thereby improving the welding quality and facilitating its promotion and use. At the same time, the output shaft of the motor drives the screw rod to rotate to adjust the position of the arc-shaped support plate, thereby increasing the scope of application.

Furthermore, the technical features described below in the different embodiments of the present invention may be combined with one another as long as they do not conflict with one another.
[0020] The present application discloses a device for eliminating the reverse deformation stress of steel plate welding, referring to Figure 1-3 The top sides of the plurality of support blocks 2 and the top side of the bracket 1 are fixedly connected with an arc-shaped support plate 3. The left side of the bracket 1 is fixedly connected with a motor 4. The output shaft of the motor 4 is fixedly connected with a screw rod 5. The plurality of support blocks 2 are spirally connected with the screw rod 5. By setting the arc-shaped support plate 3, the steel plate to be welded is placed on the top side of the bracket 1 and in contact with the arc-shaped support plate 3. At this time, since the steel plate itself has a certain flexibility, it will be placed in an arc shape with the surface of the arc-shaped support plate 3 under the influence of its own weight. When the welding operation is performed, the steel plate in the bent state can just offset the stress generated during welding, ensuring that the steel plate remains flat after welding, thereby improving the welding quality and facilitating promotion and use. At the same time, when the output shaft of the motor 4 drives the screw rod 5 to rotate, the position of the arc-shaped support plate 3 can be adjusted, thereby increasing the scope of application.
[0021] In the present application, two grooves are provided on the bottom sides of the multiple support blocks 2, and circular rollers 6 are rotatably installed on the inner walls of the multiple grooves, and the lowest points of the multiple circular rollers 6 are flush with the bottom side of the bracket 1; by setting the circular rollers 6, when the support block 2 drives the arc-shaped support plate 3 to move left or right, the rotatability of the circular rollers 6 can effectively improve the smoothness of the movement of the support block 2.
[0022] In the present application, two guide rods 7 are fixedly connected to the inner walls on the left and right sides of the bracket 1. The two guide rods 7 pass through multiple bracket blocks 2 and form a sliding connection with each other. By setting the guide rods 7, when the bracket block 2 moves left or right, the guide rods 7 can be used to limit the bracket block 2 to ensure that the bracket block 2 maintains horizontal movement to avoid offset.
[0023] In the present application, two splints 8 are fixedly connected to the left and right sides of multiple support blocks 2, and the multiple splints 8 are grouped into four and each group of splints 8 is in contact with the left and right sides of the arc-shaped support plate 3 respectively; by setting the splints 8, the splints 8 can be used to improve the stability of the connection between the arc-shaped support plate 3 and the support block 2, thereby preventing the arc-shaped support plate 3 from tilting to one side under heavy pressure when in use.
[0024] In this application, a protective cover 9 is fixedly connected to the left side of the bracket 1, and the motor 4 is located inside the protective cover 9; by setting the protective cover 9, the protective cover 9 can protect the motor 4, thereby increasing the service life of the motor 4 and reducing maintenance costs.
[0025] The standard parts used in this utility model can all be purchased from the market, and special-shaped parts can be customized according to the description in the specification and the drawings. The specific connection methods of each part adopt conventional means such as mature bolts, rivets, welding, etc. in the existing technology. The machinery, parts and equipment all adopt conventional models in the existing technology, and the circuit connection adopts the conventional connection method in the existing technology, which will not be described in detail here.
[0026] The implementation principle of the device for eliminating the reverse deformation stress of steel plate welding in the embodiment of the present application is as follows: when in use, the steel plate to be welded is placed on the top side of the bracket 1 and in contact with the arc-shaped support plate 3. At this time, since the steel plate itself has a certain flexibility, it will be placed in an arc shape in contact with the surface of the arc-shaped support plate 3 under the influence of its own weight. At this time, when the welding operation is carried out, the steel plate in the bent state can just offset the stress generated by the high temperature during welding, ensuring that the steel plate remains flat after welding, thereby improving the welding quality and facilitating its popularization and use. At the same time, the output shaft of the motor 4 drives the spiral rod 5 to rotate to adjust the arc shape. The position of the support plate 3 can improve the scope of application. When the support block 2 drives the arc-shaped support plate 3 to move left or right, the rotatability of the round roller 6 can effectively improve the smoothness of the movement of the support block 2. When the support block 2 moves left or right, the guide rod 7 can be used to limit the support block 2 to ensure that the support block 2 maintains horizontal movement to avoid offset. The splint 8 can improve the stability of the connection between the arc-shaped support plate 3 and the support block 2 to avoid the arc-shaped support plate 3 tilting to one side under heavy pressure when in use. The protective cover 9 can protect the motor 4, thereby increasing the service life of the motor 4 and reducing maintenance costs.
