Description

Technical Field

[0001] The utility model relates to the technical field of clamps, in particular to a clamping device capable of adjusting a bending machine die. Background Art

[0002] The bending machine uses a mold to process metal sheets. Usually, the lower mold is connected to the surface of the bending machine through a slot. However, during the bending process, the lower mold needs to be clamped to prevent the lower mold from sliding when the upper mold squeezes the lower mold. However, the existing clamp cannot adjust its clamping position due to its fixed structure. However, the length of the lower mold varies according to the length of the sheet. If the clamp cannot be adjusted, it cannot clamp lower molds of different lengths, which limits the use of the bending machine.

[0003] Therefore, in order to solve the defect that the lower die clamp of the bending machine cannot be adjusted, it is necessary to propose a clamping device for an adjustable bending machine die. Utility Model Content

DETAILED DESCRIPTION

[0020] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0021] See also Figure 1-Figure 2 A clamping device for an adjustable bending machine mold includes a machine body 1, a bottom mold base 2 and a lower mold 3. The bottom mold base 2 is welded to the workbench surface of the machine body 1. A slot 21 is provided on the upper surface of the bottom mold base 2. The lower mold 3 is connected to the slot 21 by a clamping block 31.

[0022] The lower die 3 is connected to the card slot 21 by means of the card block 31 , so that the lower die 3 can be easily replaced, and the lower die 3 of different lengths can be installed according to the length of the plate.

[0023] To solve the technical problem of how to adjust the clamping position, please refer to Figure 2-Figure 3 , this embodiment provides the following technical solutions:

[0024] A bidirectional screw rod 22 is movably installed in the bottom mold base 2. There are two bidirectional screw rods 22 and they are symmetrically arranged with respect to the lower mold 3. One end of the bidirectional screw rod 22 is fixedly connected to a motor 23. The bidirectional screw rod 22 is symmetrically threaded with a clamp 24 on the front and back of the bidirectional screw rod. The clamp 24 includes a positioning plate 241, and the positioning plate 241 is threadedly connected to the bidirectional screw rod 22 through a moving block 242.

[0025] A moving groove is provided on the upper surface of the bottom mold base 2 , and the moving block 242 is slidably connected with the moving groove, so that when the bidirectional screw rod 22 rotates, the moving block 242 can translate stably.

[0026] Specifically, the motor 23 is started, and the motor 23 drives the bidirectional screw 22 to rotate. Since the moving block 242 is threadedly connected to the bidirectional screw 22, and the moving block 242 is slidingly connected to the moving groove, the moving block 242 can drive the clamp 24 to translate in the direction of the lower mold 3, thereby adjusting the clamping position.

[0027] To solve the technical problem of how the clamp can clamp the lower molds of different lengths, please refer to Figure 4 , this embodiment provides the following technical solutions:

[0028] The clamp 24 includes a positioning plate 241, a support plate 243 is welded to the outer side of the positioning plate 241, a screw 248 is threadedly connected to the support plate 243, one end of the screw 248 located outside the support plate 243 is fixedly connected to a handle 249, and one end of the screw 248 located inside the support plate 243 is movably connected to a clamping plate 245, a limiting plate 246 is welded to the clamping plate 245, a sliding groove 244 is opened on the upper surface of the positioning plate 241, and the clamping plate 245 is slidably connected to the sliding groove 244 through a slider 247.

[0029] Among them, when the lower mold 3 is clamped, the limit plate 246 is moved to the outermost end to facilitate pushing the clamping block 31 from the side end of the clamping slot 21. When adjusting the clamping position, the limit plate 246 needs to be moved to the outer end to facilitate the movement of the clamp 24 so that the limit plate 246 can fit with the front and rear ends of the lower mold 3.

[0030] Specifically, when the limit plate 246 moves to the front and rear ends of the lower mold 3 and fits together, the motor 23 is turned off and the handle 249 is turned. The handle 249 drives the screw 248 to rotate. The screw 248 can push the clamping plate 245 and drive the slider 247 to move in the slide groove 244 until the clamping plate 245 fits together with the left and right ends of the lower mold 3, thereby clamping lower molds 3 of different lengths. The limit plate 246 can prevent the lower mold 3 from sliding forward and backward, and the clamping plate 245 can prevent the lower mold 3 from shaking left and right, thereby improving the stability of the installation of the lower mold 3.

[0031] Working principle: When using the clamping device of the adjustable bending machine mold, first engage the lower mold 3 in the slot 21, then rotate the screw 248 to move the limit plate 246 outward, then start the motor 23, the motor 23 drives the bidirectional screw 22 to rotate, so that the front and rear clamps 24 move toward the lower mold 3 until the limit plate 246 fits with the front and rear ends of the lower mold 3, turn off the motor 23, and then rotate the screw 248, the screw 248 pushes the clamping plate 245 movably connected thereto, until the clamping plate 245 fits with the left and right ends of the lower mold 3, thereby clamping lower molds 3 of different lengths.
