Description

Technical Field

[0001] The invention relates to a metal sheet deformation control device, in particular to a arc surface metal sheet welding deformation control device. Background Art

[0002] Welding deformation refers to the changes in shape and size of the workpieces being welded due to the uneven temperature field during welding. It is an inevitable problem in the welding process, and welding deformation is particularly obvious in metal sheets. For metal sheet welding with certain artistic shapes and subsequent grinding and polishing to show artistic effects, traditional welding deformation control methods such as reasonable welding sequence, welding methods and specifications, and accelerated heat dissipation have limited effects, and the anti-deformation setting and hammering weld method in advance are not effective in this type of product. Welding deformation increases the workload of the next grinding and polishing process and affects the overall artistic effect of the product. Summary of the invention

[0003] Purpose of the invention: The purpose of the present invention is to provide a device for controlling arc-shaped metal sheet welding deformation, so as to solve the problem that arc-shaped metal sheet is easily deformed, thus affecting the subsequent processes.

[0004] Technical solution: The arc metal sheet welding deformation control device described in the present invention includes a base, a placement groove is opened on the base, a pad is arranged in the placement groove, an adaptive pressure strip is arranged on the base, a socket is arranged on both sides of the pressure strip, and bolt tensioning devices are arranged on both sides of the base, and the bolt tensioning device is detachably connected to the socket.

[0005] To facilitate movement and reduce weight, the side of the bottom plate is provided with openings and handles.

[0006] It is used to speed up the heat conduction at the weld without affecting the back forming of the weld. The pad is a copper pad. The placement groove is a V-shaped placement groove.

[0007] In order to rigidly fix the panels on both sides of the weld, the pressure strip is a metal pressure strip, and a through hole is opened on the base, and a screw is installed in the through hole.

[0008] Beneficial effects: The present invention is simple to manufacture and easy to operate. It can solve the problem that the welding tooling for large metal wall panels cannot be fixed and is difficult to operate. It can also rigidly fix the weld area and quickly conduct the welding heat, thereby improving work efficiency and effectively reducing welding deformation, reducing the workload of subsequent processes, and improving the artistic effect of the product. By using this device, the workload of subsequent weld correction can be reduced by 30%, and the workload of grinding and polishing can be reduced by 20%, thereby improving labor productivity and saving a lot of labor costs.

[0012] The present invention will be further described below in conjunction with the accompanying drawings.

[0013] like Figure 1-3 As shown, the arc surface metal sheet welding deformation control device includes a base 1, a V-shaped placement groove is provided on the base, an opening and a handle are provided on the side of the base 1, a copper pad 2 is provided in the placement groove, and the copper pad 2 also has a groove adapted to the V-shaped groove, an adapted pressure strip 3 is provided on the base 1, and a holder 7 is provided on both sides of the pressure strip 3, and a through hole is provided on the holder 7, and a bolt tensioning device 4 is provided on both sides of the base 1, and the bolt tensioning device 4 includes a pin seat 8, one end of the pin seat 8 is provided with a through hole and is connected to the holder 7 through a pin 9, and the other end is installed with a screw rod 10 and a nut 11.

[0014] When using the present invention, first complete the assembly of the metal plate 5 to be welded, then combine the steel structure base 1 and the copper pad 2 and install them on the back of the weld to be welded, align the center of the weld with the V-groove of the pad, install the metal strip 3 on the front of the weld 6 to be welded, and insert the bolt fastener 4 from the back of the weld along the two ends of the steel structure bottom plate inwardly to the front of the weld and clamp the strip through the latch, tighten the strip by tightening the nuts at both ends of the base, and tightly fix the position to be welded between the copper pad and the metal strip. Finally, the welding is completed under a reasonable welding method and welding sequence. During the welding process, the weld is always in a compressed state and the welding heat can be quickly conducted out through the copper pad, so as to achieve the purpose of reducing welding deformation. This device is not only suitable for flat welding position welding, but also more suitable for horizontal welding and vertical welding of space assembly wall panels that are not suitable for conventional welding tooling.
