Description

Technical Field

[0001] The invention belongs to the field of welding equipment, and in particular relates to a T-shaped component local deformation correction tool and a use method. Background Art

[0002] Welding is a manufacturing process and technology that joins metals or other thermoplastic materials by heating, high temperature or high pressure. During the welding process, welding stress is generated due to internal stress caused by temperature changes and material phase changes, which will cause deformation of the welded parts. Deformation of the welded parts will cause the welded products to fail to meet the use requirements, etc., so the welding deformation needs to be corrected. Aluminum products are more likely to deform during the production process than steel products, and the deformation is large. The subsequent correction work is more difficult, time-consuming, and labor-intensive. At present, for the welding of aluminum alloy T-shaped components, a rigid fixing method is generally adopted in which a pressure iron is used to press the plate to the construction platform before welding. However, the pressure iron is heavy and it takes a long time for the crane to move the pressure iron, which also increases the difficulty and labor intensity of the workers and is time-consuming. Therefore, in order to avoid the shortcomings of the prior art, it is necessary to improve the prior art. Summary of the invention

[0014] Step 3, raising the jack so that the tensioning device tightens the prepared welding area of ​​the T-shaped component to generate pre-deformation to offset the deformation generated during the welding process, and then performing a welding process on the T-shaped component;

After welding, move the tensioner and gasket to the next area where welding is required, and continue the welding operation. The moving process is simple and easy to operate. The local deformation caused by welding is corrected by the jack, the tooling body, the tensioning device and the gasket.

The local deformation correction tool for the T-type component can also correct the T-type component when deformation occurs after welding. The tensioning device is moved along the tensioning part to the deformation area that needs to be corrected. The jack is raised to drive the tensioning device to lift the deformed part of the T-type component upward to produce pre-deformation. By heating the deformed area of ​​the T-type component, the pre-deformation offsets the deformation caused by the heating process, thereby correcting the deformed area of ​​the T-type component.

[0033] Please also read Figures 2 to 4 Now, the local deformation correction tool for the T-shaped component provided in an embodiment of the present invention is described.

[0034] like Figures 2 to 4 As shown, a local deformation correction tool for a T-shaped component 400 of the present invention is used for constraining and correcting the T-shaped component 400 during welding, and includes a tool body 100, a tensioning device 300 and a gasket 500. The tool body 100 is a plate structure, and the tool body 100 includes a support portion 110 and a tensioning portion 120. A jack 200 is arranged below the support portion 110, and the upper end of the jack 200 is connected to the support portion 110, and the lower end of the jack 200 can be connected to the T-shaped component 400. The upper end of the tensioning device 300 is connected to the upper end surface of the tensioning portion 120, and the lower end of the tensioning device 300 can be connected to the T-shaped component 400. The gasket 500 is arranged between the support portion 110 and the T-shaped component 400, and the gasket 500 can move along the tensioning portion 120.

[0035] The tooling body 100 includes a supporting portion 110 and a tensioning portion 120. By lifting the supporting portion 110 with the jack 200, the tensioning portion 120 connected to the supporting portion 110 can be driven to rise, thereby driving the tensioning device 300 to rise and lift the T-shaped component 400 upward, and pre-deforming the T-shaped component 400 to offset the deformation caused by the welding process; the local deformation caused by welding is corrected by the jack 200, the tooling body 100, the tensioning device 300 and the gasket 500, and there is no need for Figure 1 As shown, 600 iron weights weighing several tons are used for the traditional rigid fixing method. The overall welding process is simple and convenient, which also reduces the difficulty and labor intensity of the workers and shortens the time.

[0036] The tensioning device 300 can be moved along the tensioning portion 120 , or taken out from the tensioning portion 120 and then connected above the area on the tensioning portion 120 that needs to be prepared for welding, so as to facilitate adjustment when welding different positions of the T-shaped component 400 .

[0037] Exemplarily, a reinforcing rib 130 is provided at the connection between the support portion 110 and the tensioning portion 120. The support portion 110 and the tensioning portion 120 are rigidly connected. The jack 200 needs to lift the support portion 110 to drive the tensioning portion 120 to rise. Therefore, the connection between the support portion 110 and the tensioning portion 120 is prone to deformation. Providing the reinforcing rib 130 can increase the strength and rigidity of the connection between the support portion 110 and the tensioning portion 120.

[0038] Exemplarily, the upper end of the support portion 110 protrudes outward to form a support plate 140, and the bottom surface of the support plate 140 abuts against the top end of the jack 200. The outwardly protruding support plate 140 provides the jack 200 with a contact surface for applying pressure. Increasing the contact surface with the jack 200 can also prevent it from falling off when pressure is applied.

[0039] For example, Figure 3 As shown, the tensioning device 300 includes two tensioning plates 310 arranged opposite to each other. The two tensioning plates 310 can move along the tensioning portion 120. The tensioning portion 120 and the T-shaped component 400 are fastened by the two tensioning plates 310 to facilitate movement and disassembly. The two tensioning plates 310 are arranged opposite to each other to maintain force balance.

[0040] Exemplarily, a protruding anti-slip strip 320 is provided at the upper end of the tensioning plate 310, and the bottom surface of the anti-slip strip 320 abuts against the top surface of the tensioning part 120. A positioning groove 330 is opened at the lower end of the tensioning plate 310, and the positioning groove 330 is plugged and matched with the side wing part of the T-shaped component 400 for positioning. The protruding anti-slip strip 320 can increase the contact area abutting against the top of the tensioning part 120. When the tensioning part 120 rises, the contact position between the tensioning part 120 and the anti-slip strip 320 is subjected to greater force, making the tensioning plate 310 easy to fall off. The protruding anti-slip strip 320 can ensure the safety of construction personnel; the protruding part of the T-shaped component 400 is plugged into the positioning groove 330, that is, the side wing part of the T-shaped component 400 is plugged into the positioning groove 330, so as to position the T-shaped component 400 and drive the T-shaped component 400 to be lifted upward when the tensioning plate 310 rises.

[0041] Exemplarily, a mother material anti-damage block 340 protruding outward is also provided on the lower side of the positioning groove 330, and the upper end surface of the mother material anti-damage block 340 can abut against the bottom surface of the side wing part of the T-shaped component 400. The mother material anti-damage block 340 protrudes outward from both sides of the tensioning plate 310 to increase the contact area with the mother material. The mother material anti-damage block 340 contacts the bottom surface of the protruding part of the T-shaped component 400, and the force is large, which can easily cause damage to the mother material, that is, it is easy to cause damage to the T-shaped component 400, thereby increasing the force area of ​​this area and reducing damage to the mother material.

[0042] The present invention also provides a method for using a local deformation correction tool of a T-shaped component 400, wherein the local deformation correction tool of the T-shaped component 400 is used to correct a workpiece before welding, and the method comprises the following steps:

[0043] Step 1: Before welding, the local deformation correction tool of the T-shaped component 400 is placed on the upper surface of the T-shaped component 400, and the jack 200 is arranged on the upper surface of the T-shaped component 400;

[0044] Step 2: Move the tensioning device 300 along the tensioning portion 120 to the area to be welded, connect the upper end of the tensioning device 300 to the tensioning portion 120, connect the lower end of the tensioning device 300 to the T-shaped assembly 400, move the gasket 500 along the tensioning portion 120 to an end away from the support portion 110, and arrange the gasket 500 between the support portion 110 and the T-shaped assembly 400;

[0045] Step three, such as Figure 1 As shown, the jack 200 is raised, so that the tensioning device 300 tensions the prepared welding area 410 of the T-shaped component 400 to generate pre-deformation to offset the deformation generated during the welding process, and then the T-shaped component 400 is subjected to the welding process;

[0046] Step 4: Figure 2 As shown, after welding, the tensioning device 300 is moved to the next area to be welded, and the above steps 2 and 3 are repeated.

[0047] The mobile tensioning device 300 and the gasket 500 can correct the local welding deformation of different areas of the T-shaped component 400. The operation is convenient and welding can be performed continuously. Specifically, the pre-deformation is generally 30 mm.

[0048] The present invention also provides a method for using a local deformation correction tool of a T-shaped component 400, wherein the local deformation correction tool of the T-shaped component 400 is used to correct a workpiece after welding, and the method comprises the following steps:

[0049] Step 1: After welding, when the T-shaped component 400 is deformed, the local deformation correction tool of the T-shaped component 400 is placed on the upper surface of the T-shaped component 400, and the jack 200 is set on the upper surface of the T-shaped component 400;

[0050] Step 2: Move the tensioning device 300 along the tensioning portion 120 to the deformed area, connect the upper end of the tensioning device 300 to the tensioning portion 120, connect the lower end of the tensioning device 300 to the T-shaped assembly 400, move the gasket 500 along the tensioning portion 120 to an end away from the supporting portion 110, and arrange the gasket 500 between the supporting portion 110 and the T-shaped assembly 400;

[0051] Step three, raising the jack 200, allowing the tensioning device 300 to tension the deformed area of ​​the T-shaped component 400, generating pre-deformation to offset the deformation generated during the heating process, and then heating and correcting the deformed area of ​​the T-shaped component 400.

[0052] The deformed area is stretched to perform pre-deformation so that the pre-deformation can offset the deformation generated during the heating process, thereby heating and correcting the deformed area of ​​the T-shaped component 400.

[0053] The local deformation correction tool for a T-shaped assembly 400 provided by the present invention has the following beneficial effects compared with the prior art:

[0054] The tooling body 100 of the present invention includes a supporting portion 110 and a tensioning portion 120. The tensioning device 300 connects the tensioning portion 120 and the T-shaped assembly 400. The jack 200 lifts the supporting portion 110 to drive the tensioning portion 120 to rise, so that the tensioning device 300 tensions the area of ​​the T-shaped assembly 400 to be welded, so that the area to be welded is pre-deformed. In this way, the welding deformation caused by the welding stress generated inside the welding area 410 during the welding process will offset the pre-deformation, thereby correcting the local deformation generated during the welding process and avoiding large deformation during welding. The gasket 500 is arranged between the supporting portion 110 and the T-shaped assembly 400. During welding, the welding area 410 of the T-shaped assembly 400 will sink due to deformation caused by the welding stress. The lifting jack 200 drives the tensioning device 300 so that the tensioning device 300 pulls the welding area 410 upward to generate a pre-deformation of upward bending. In this way, the upward pre-deformation after welding can offset the upward deformation generated during the welding process. Downward deformation; the two ends of the welding area 410 of the T-shaped component 400 will bend upward and apply pressure to the gasket 500. The function of the gasket 500 is to increase the force-bearing area to maintain the balance when the pressure is applied. The local deformation caused by welding is corrected by the jack 200, the tooling body 100, the tensioning device 300 and the gasket 500. There is no need for 600 pieces of pressure iron weighing several tons to perform the traditional rigid fixing method. The overall welding process is simple and convenient, which also reduces the difficulty and labor intensity of the workers and shortens the time. The local deformation correction tool of the T-shaped component 400 can also correct the T-shaped component 400 when deformation occurs after welding. The tensioning device 300 is moved along the tensioning part 120 to the deformation area that needs to be corrected. The jack 200 is raised to drive the tensioning device 300 to lift the deformed part of the T-shaped component 400 upward to produce pre-deformation. By heating the deformed area of ​​the T-shaped component 400, the pre-deformation offsets the deformation caused by the heating process, thereby correcting the deformed area of ​​the T-shaped component 400.

[0055] The above is only a preferred embodiment of the present invention. It should be pointed out that for ordinary technicians in this technical field, several improvements and substitutions can be made without departing from the technical principles of the present invention. These improvements and substitutions should also be regarded as the scope of protection of the present invention.
