Abstract
Description
Technical Field
[0001] This utility model relates to the field of CNC machining technology, specifically to a CNC sheet metal bending device. Background Technology
[0002] CNC sheet metal bending is a process that uses CNC devices to bend metal sheets. It is widely used in industries such as machinery manufacturing, automobile manufacturing, aerospace, electronics, and building decoration. CNC sheet metal processing is characterized by high precision, high efficiency, flexibility, and repeatability.
[0003] CNC sheet metal bending includes a worktable, upper die, lower die, CNC system, sensors, and feedback devices. During operation, the sheet metal to be processed is placed on the worktable, and the edge to be bent is moved to the lower die. Hydraulic drive causes the upper die to move downwards, bending the sheet metal. In existing technologies, since the sheet metal often has multiple edges to be bent and quick sheet metal changes are required, manual adjustment of the direction is often used, which is efficient. However, during manual adjustment, the lower die is exposed, posing a risk of hand contact during adjustment. Misoperation in this situation could injure the worker, posing a safety hazard and indicating room for technological improvement. Utility Model Content
[0004] This invention aims to solve the aforementioned technical problem of the risk of hand contact with the lower mold when manually adjusting sheet metal parts, and provides a CNC sheet metal bending device.
[0005] To solve the above-mentioned technical problems, the technical solution provided by this utility model is as follows: a CNC sheet metal bending device, including a mounting part, the mounting part being a groove-shaped structure with an opening at the upper end; a plurality of assembly holes are provided on the inner bottom surface of the mounting part; a lower die is detachably mounted in the mounting part, the top surface of the lower die being flush with the mounting part; further comprising:
[0006] A protective cover is detachably installed above the mounting part. The upper end of the protective cover is fixedly connected to an operating box. The operating box contains a drive assembly. The output end of the drive assembly is connected to an upper mold. The upper mold can extend into the protective cover, the mounting part, and the lower mold.
[0007] Support plate; located at the upper front end of the mounting part, the support plate is provided with symmetrically movable limiting components for limiting the position of the plate.
[0008] Furthermore, a workbench is provided below the mounting part. The workbench is hollow inside and has an opening at the front end, and a storage compartment is slidably arranged inside the opening.
[0009] Furthermore, the protective cover is provided with connecting plate one on both sides and near the lower end, and the mounting part is provided with connecting plate two on both sides and near the upper end.

[0010] Furthermore, the limiting component includes a base plate symmetrically movable on a support plate, an electric push rod on the base plate, a connector at the output end of the electric push rod, an upper support arm rotatably mounted on the connector, and a pressure plate fixedly connected to the end of the upper support arm; a T-shaped piece is provided on the base plate, and an H-plate is hinged between the T-shaped piece and the upper support arm.
[0011] Furthermore, the support plate is provided with a strip groove, and a motor is provided at one end of the support plate. The output end of the motor extends into the strip groove and is provided with a bidirectional screw. Nut blocks are threadedly connected to the outside of the bidirectional screw and near both ends. The upper end of each nut block extends out of the strip groove and is connected to the corresponding base plate.
[0012] The advantages of this utility model compared with the prior art are as follows:
[0013] The lower mold is installed between the mounting part and the protective cover, so that the lower mold is protected. When the plate to be bent is manually placed, it can actively prevent the hand from reaching in, thus improving safety.
[0014] It is equipped with adjustable spacing limit components, which facilitates quick pressing of the board and prevents the board from lifting and injuring the workers' hands due to the large downward force when bending, thus further improving safety.

[0023] Combined with appendix Figure 1 , 2 The mounting part 1 has a groove-shaped structure with an opening at the top. The bottom surface of the mounting part 1 has several assembly holes 2. A lower mold 3 is detachably installed inside the mounting part 1. The lower mold 3 has two assembly holes corresponding to the assembly holes, which makes it easy to install the lower mold 3 in different positions according to the actual size and usage needs, or to adjust the installation position when multiple lower molds 3 are used at the same time. The top surface of the lower mold 3 is flush with the mounting part 1, so that the plate is stable when placed.
[0024] Combined with appendix Figure 1 , 2 It also includes a protective cover 6; it is detachably installed on the top of the mounting part 1. The upper end of the protective cover 6 is fixed to the operating box 7. Specifically, the protective cover 6 has a connecting plate 1 on both sides and near the lower end, and the mounting part 1 has a connecting plate 2 on both sides and near the upper end. The connecting plate 2 is connected to the connecting plate 1 by bolts and nuts. In special cases, such as when it is necessary to install a large lower mold 3, the protective cover 6 and the operating box 7 can be removed to expose the upper end of the mounting part 1 for easy operation.
[0025] In addition, the control box 7 is equipped with a drive assembly, the output end of which is connected to the upper mold 8. The upper mold 8 can extend into the protective cover 6, the mounting part 1, and the lower mold 3 to perform bending operations.
[0026] Combined with appendix Figure 1 , 2 It also includes a support plate 9, located at the upper front of the mounting part 1; the support plate 9 is symmetrically movable with a limiting component for limiting the plate.
