Description

Technical Field

[0001] The utility model relates to the field of metal forming, in particular to a device for rapid bending of plate-shaped metal. Background Art

[0002] Sheet metal parts forming is to make the stress in the deformation area of ​​the sheet metal exceed the yield point to produce permanent deformation. If the local stress exceeds the strength limit, the sheet metal will break. The sheet metal plastic deformation theory is the theoretical basis of sheet metal forming work. Sheet metal bending equipment is needed in the sheet metal forming process.

[0003] The utility model patent with publication number CN 221184257 U in the prior art proposes a device for rapid sheet metal bending. This device solves the problem that most existing bending devices on the market do not have the function of limiting the width of the sheet metal, requiring the user to manually support the bending process. It also solves the problem that the limiting mechanism does not have the function of limiting the thickness of the sheet metal.

[0004] However, the bending effect of its bending device is single, and it can only realize bending operations of one shape or size. It cannot realize the convenient replacement capability of the upper and lower mold bases. When different bending requirements arise, it is necessary to switch equipment, which is troublesome and inefficient. At the same time, it requires manual pre-operation when limiting the metal, and cannot be operated synchronously during the bending process, which will also reduce the bending efficiency of the metal plate. Therefore, we need to upgrade and transform the existing technology to overcome its existing problems and shortcomings. Utility Model Content

[0024] like Figure 1 -4, the present embodiment provides a device for rapid bending forming of plate metal, including a device body 1, which contains a workbench 2, a mounting seat 5, an adjustment component 8 and a limit component 9. An upper bracket 3 is provided at the upper end of the workbench 2, and a telescopic rod 4 is provided at the center of the upper bracket 3. A guide hole 31 is provided at the lower end of the upper bracket 3, the mounting seat 5 is connected to the lower end of the telescopic rod 4, and an upper die base 6 is installed at the lower end of the mounting seat 5.

[0025] Preferably, the adjustment assembly 8 includes an articulated seat 81 and an inserting slot 85, a threaded rod 82 and a guide rod 84 are rotatably provided on the inner side of the articulated seat 81, the outer end of the threaded rod 82 is connected to a motor 83, the articulated seat 81 is fixed on the workbench 2, the threaded rod 82 is threaded through one side of the lower end of the upper bracket 3, the guide rod 84 is movable through the guide hole 31 on the other side of the upper bracket 3, a plug-in block 87 is inserted in the inserting slot 85, and a fixing hole 86 is correspondingly provided in the inserting slot 85 and the inserting block 87, and a fixing bolt 88 is installed in the fixing hole 86, and a nut 89 is installed at the outer end of the fixing bolt 88. The inserting slot 85 is provided on the mounting seat 5 and two groups are symmetrically provided. The inserting block 87 is fixed to the top of the upper die base 6, and two groups of fixing holes 86 are provided and correspond to the fixing bolts 88.

[0026] The upper bracket 3 is driven to move forward and backward by the cooperation of the threaded rod 82 and the guide rod 84, the upper mold base 6 is installed by the cooperation of the plug-in slot 85 and the plug-in block 87, and the upper mold base 6 is limited by the cooperation of the fixing hole 86 and the fixing bolt 88, so as to facilitate the quick switching of the upper mold base 6 and the movement of the position of the upper mold base 6 and make it match with the lower mold base 7.

[0027] Preferably, the limiting assembly 9 includes a side plate 91, a movable shaft 92 movably passing through the side plate 91, a pressure plate 93 is provided at the lower end of the movable shaft 92, a spring 94 is provided between the pressure plate 93 and the side plate 91, the side plate 91 is fixed to the side of the mounting seat 5, the spring 94 is movably sleeved on the outside of the movable shaft 92, a limiting plate 95 is provided on the top of the movable shaft 92, and the limiting plate 95 is located at the upper end of the side plate 91;

[0028] The spring 94 and the pressure plate 93 cooperate to control the elastic expansion and contraction of the movable shaft 92, thereby facilitating the compression and positioning of the metal to be bent, thereby preventing sliding and offsetting during bending. The bending efficiency is improved without the need for manual pre-positioning of the metal.

[0029] The principle and process of use of the utility model: when using it, you can first place the sheet metal on the lower die seat 7, drive the telescopic rod 4 to work, the telescopic rod 4 drives the mounting seat 5 and the upper die seat 6 to descend, and the upper die seat 6 cooperates with the lower die seat 7 to bend the metal. During the descent of the upper die seat 6, the pressing plate 93 contacts the metal first, and the pressing plate 93 pushes the movable shaft 92 to rise and squeezes the spring 94 to contract. The spring 94 exerts an elastic force on the metal and presses it tightly on the workbench 2. As the upper die seat 6 moves downward, the pressing effect becomes more obvious, which can effectively keep the metal stable during bending. To prevent it from sliding and offsetting, when facing different bending shape requirements, the motor 83 can be controlled to work, and the motor 83 drives the threaded rod 82 to drive the upper bracket 3 to move and make the mounting base 5 located directly above the required lower die base 7. Then the original upper die base 6 is disassembled and replaced with the corresponding upper die base 6, and the upper die base 6 is plugged into the plug slot 85 through the plug-in block 87. Use the fixing bolt 88 and plug it into the fixing hole 86, and fix the nut 89 at the other end of the fixing bolt 88. At this time, the new die base can be used to continue the bending operation, which effectively improves the practicality of the device.
