The motor and the chain need to be installed on the sprocket mounting plate. The sprocket mounting plate is made of a stainless steel sheet by bending and punching the stainless steel sheet.

[0003] The existing bending device is manually placed between the lower die and the upper die. After one end of the plate is pressed against the inner positioning plate, the upper die is driven by hydraulic pressure to bend the plate. During the bending process, the plate needs to be held continuously by a human to ensure processing accuracy, which increases labor intensity. Utility Model Content

[0004] In order to overcome the shortcomings of the prior art, the purpose of the utility model is to provide a plate bending auxiliary positioning structure, by pushing the plate to the top of the lower mold, the front end of the plate is against the inner positioning plate, and by adjusting the position of the elastic tightening part, the elastic tightening part presses the plate against the side plate to position the plate. When bending, there is no need for manual continuous holding of the workpiece.

[0005] The technical solution adopted by the utility model is as follows:

[0006] A plate bending auxiliary positioning structure comprises an inner positioning plate, a side plate, an elastic top tightening member and an adjusting mechanism installed on a base, wherein the inner positioning plate is fixedly connected to the base and is located on the inner side of a lower die, the side plates and the elastic top tightening member are both arranged on the outer side of the lower die, the side plates are fixedly installed on the base, the side plates and the elastic top tightening member are located on both sides of the plate, and the movable end of the adjusting mechanism is fixedly connected to the elastic top tightening member for adjusting the distance between the side plates and the elastic top tightening member.

[0007] Compared with the prior art, the beneficial effects of the present invention are:

[0008] 1. By pushing the sheet to the top of the lower die, the front end of the sheet is pressed against the inner positioning plate. By adjusting the position of the elastic top tightening part, the elastic top tightening part presses the sheet against the side plate to position the sheet. When bending, there is no need to hold the workpiece continuously manually.

[0009] 2. Using an elastic top tightening member instead of manual gripping will result in plates of different specifications requiring adjustment of the position of the elastic top tightening member. Therefore, by providing an adjustment mechanism and adjusting the position of the elastic top tightening member, plates of different specifications can be accommodated.

[0010] As a preferred embodiment of the utility model, the adjustment mechanism includes two mounting blocks mounted on the base, a screw rod is rotatably mounted between the two mounting blocks, a slider is screwed on the screw rod, and the lower end surface of the slider is in contact with the upper end surface of the base;

[0011] The elastic tightening member includes a first plate body, a compression spring and two first rod bodies. Two through holes are horizontally opened on the slider. The two first rod bodies are slidably connected to the through holes, and both ends extend out of the through holes. One end of the two first rod bodies is fixedly connected to the first plate body, and the other ends of the two first rod bodies are installed with limit blocks. A compression spring is installed between the first plate body and the slider.

[0012] Beneficial effect: By rotating the screw rod, the sliding movement can be driven, thereby driving the first plate body to move, and the distance between the first plate body and the side plate is adjusted to be smaller than the width of the plate. The plate is inserted between the first plate body and the side plate, so that the elasticity of the compression spring presses the plate tightly, and the movement of the first plate body is guided by setting the first rod body, and the first rod body is prevented from being separated from the through hole by setting a limit block.

[0013] As a preferred embodiment of the utility model, it also includes an auxiliary support plate, which includes a vertical plate and a horizontal plate. The vertical plate is fixedly connected to the upper end surface of the base, the inner wall of the vertical plate is in contact with the slider, and the horizontal plate is fixedly connected to the upper end of the vertical plate. The upper end surface of the horizontal plate and the upper end surface of the lower mold are located in the same horizontal plane, and the lower end surface of the first plate body is in contact with the upper end surface of the horizontal plate.

[0014] Beneficial effect: By setting up an auxiliary support plate, since the upper end surface of the lower mold is often narrower, the horizontal plate can assist the lower mold to support the plate, and at the same time, it can guide the movement of the first plate body. The vertical plate is used to support the horizontal plate, and at the same time, it can limit the movement of the slider.

[0015] As a preferred embodiment of the present invention, the inner side of the first plate body is provided with a chamfer, and when the plate is pushed in, the plate contacts the chamfer, forcing the first plate to move toward the slider.

[0016] Beneficial effect: By setting the chamfer, the plate can be laid flat, and then the plate can be pushed directly toward the inner positioning plate. During the pushing process, the plate squeezes the first plate body through the chamfer. After the plate is completely pushed into the lower die, the elasticity of the compression spring presses the plate tightly.

[0017] As a preferred embodiment of the present invention, the other ends of the two first rods are provided with threads, and the two limit blocks are respectively screwed on the corresponding first rods.

[0018] Beneficial effect: By setting the screw-connected limit block, installation is facilitated and the preload force of the compression spring can be adjusted. BRIEF DESCRIPTION OF THE DRAWINGS
