Abstract
Description
Technical Field
[0001] This utility model relates to the field of bending device technology, and in particular to a sheet metal bending device. Background Technology
[0002] Sheet metal processing is a comprehensive cold working process for thin metal sheets (usually less than 6mm), including shearing, punching / cutting / combined cutting, bending, welding, riveting, splicing, and forming (such as car bodies). Its significant characteristic is that the thickness of the same part is consistent. Products processed by sheet metal processing are called sheet metal parts. One type of sheet metal bending device has the following structure:
[0003] 1. Frame: The basic support structure of the bending device, which plays a role in stabilizing the machine body, bearing other components, and ensuring that the equipment remains stable during operation and does not shake.
[0004] 2. Workbench: This is the flat surface on which the material to be processed is placed, providing a stable processing platform;
[0005] 3. Bending mechanism: It is responsible for bending the sheet metal and is the core component for realizing the bending function.
[0006] When the bending device is working, the bending mechanism rotates upward to bend the sheet metal. During this process, the bending plate in the bending mechanism flips over. If the workers are not observant, they may be accidentally hit by the flipped bending plate, resulting in personal injury. Summary of the Invention
[0007] To address the shortcomings of existing technologies, this utility model provides a sheet metal bending device that solves the technical problem that when the bending device is in operation, the bending mechanism rotates upward to bend the sheet metal. During this process, the bending plate in the bending mechanism flips over, which can easily cause personal injury accidents if workers are not observant.
[0008] To achieve the above objectives, this utility model provides the following technical solution:
[0009] A sheet metal bending device includes a housing. A protective plate is provided on the outside of the housing to shield the bending mechanism. A fixing mechanism for mounting the protective plate is provided on the side of the housing near the protective plate. The fixing mechanism includes a mounting base, a moving groove, a mounting block, a limiting shaft, a slot, and a locking block. The mounting base is fixedly mounted on the outside of the housing. The moving groove is located outside the mounting base and is used for sliding of the protective plate. The mounting block is slidably connected inside the moving groove and fixedly mounted on the outside of the protective plate. One end of the limiting shaft is locked inside the moving groove and restricts the lateral movement of the protective plate. The mounting block is slidably connected outside the limiting shaft. The slot is located outside the mounting base, and the locking block is locked inside the slot.
[0010] Preferably, the protective plate is fixedly installed with a handle, which is concave to facilitate operation of the protective plate.
[0011] Preferably, the upper surface of the mounting base is provided with a screw rod, the external thread of which is connected to a nut. The mounting base has an opening on the side corresponding to the screw rod, and the other end of the limiting shaft is connected to the screw rod through the opening, which facilitates the disassembly and assembly of the protective plate.
[0012] Preferably, the mounting base is provided with a spring on the outside, the locking block is fixedly connected to the outside of the spring, and the mounting base is provided with a storage groove on the outside, with the spring fixedly connected to the inside of the storage groove, thereby improving the stability of the locking block installation.
[0013] Preferably, the external fixed connection of the card block is a pull ring, which is located on the side of the card block away from the moving groove, making it easy to pull the card block.
[0014] Compared with the prior art, the present invention has the following beneficial effects:
[0015] 1. Before the sheet metal bending device starts working, push the protective plate upward to cover the bending mechanism. Then push the locking block to move it into the moving groove. At this time, the locking block is located on the lower surface of the mounting block to restrict the downward movement of the mounting block. The protective plate is now installed. The protective plate can surround the bending plate in the bending mechanism to prevent the operator from accidentally contacting it, thus improving the operator's safety and avoiding the risk of personal injury caused by accidental contact with the bending mechanism.
[0016] 2. After the connection between the nut and the screw is released, pull the limit shaft to make the limit shaft drive the screw to release the connection between the opening and the moving groove. At this time, the connection between the limit shaft and the mounting block is released, and the protective plate can be removed. The bending plate is exposed, which makes it easier to repair the bending plate and reduces the difficulty of the work. Attached Figure Description

[0023] This application provides a sheet metal bending device that effectively solves the technical problem that when the bending device is working, the bending mechanism rotates upward to bend the sheet metal. During this process, the bending plate in the bending mechanism flips over, and if the workers are not observant, they are easily hit by the flipped bending plate, which can lead to personal injury accidents. Example
[0024] like Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, the technical solution in this application embodiment effectively solves the technical problem that when the bending device is working, the bending mechanism rotates upward to bend the sheet metal. During this process, the bending plate in the bending mechanism flips over, and if the workers are not observant, they are easily hit by the flipped bending plate, leading to personal injury accidents. The overall idea is as follows:
[0025] To address the problems existing in the prior art, this utility model provides a sheet metal bending device, including a housing 1. A protective plate 2 for shielding the bending mechanism is provided on the outside of the housing 1. The protective plate 2 is composed of a concave plate and a cuboid. A handle 9, which is concave, is fixedly installed on the outside of the protective plate 2. A fixing mechanism for installing the protective plate 2 is provided on the side of the housing 1 near the protective plate 2. The fixing mechanism includes a mounting base 3, a moving groove 4, a limiting shaft 6, a slot 7, and a locking block 8. The mounting base 3 is fixedly installed on the outside of the housing 1, and the moving groove... 4 is opened on the outside of the mounting base 3 and is used for the sliding of the protective plate 2. The mounting block 5 is slidably connected to the inside of the moving groove 4. The mounting block 5 is fixedly installed on the outside of the protective plate 2. One end of the limiting shaft 6 is engaged in the inside of the moving groove 4 and restricts the lateral movement of the protective plate 2. The limiting shaft 6 is composed of a round shaft and a cuboid. The mounting block 5 is slidably connected to the outside of the limiting shaft 6. The slot 7 is opened on the outside of the mounting base 3 and communicates with the inside of the moving groove 4. The locking block 8 is engaged in the inside of the slot 7. The mounting block 5 is located on the upper surface of the locking block 8. The locking block 8 is T-shaped.
[0026] The upper surface of the mounting base 3 is provided with a screw 10, and a nut 11 is connected to the external thread of the screw 10. The mounting base 3 has an opening 12 on the side corresponding to the screw 10, and the other end of the limiting shaft 6 is connected to the screw 10 through the opening 12.
[0027] The mounting base 3 has a storage slot 14 on its outside. A spring 13 is fixedly connected inside the storage slot 14, and a locking block 8 is fixedly connected to the outside of the spring 13.
[0028] A pull ring 15 is fixedly connected to the side of the card block 8 away from the moving groove 4. The pull ring 15 is composed of a rope and a ring.
[0029] Protective plate 2: Used to shield internal bending mechanisms and other components when the device is working, preventing operators from accidentally coming into contact with them, improving operator safety, and reducing the risk of personal injury caused by accidental contact with rotating parts;
[0030] Handle 9: It is convenient for operators to grip so as to push the protective plate 2, which improves the flexibility and efficiency of operation and reduces labor intensity;
[0031] Mounting base 3, moving groove 4 and limiting shaft 6: Mounting base 3 is the mounting carrier for fixing other components of the mechanism and provides a support structure for the movement of the protective plate 2. The moving groove 4 is opened outside the mounting base 3. The protective plate 2 slides in the moving groove 4 through the mounting block 5 to realize the up and down movement of the protective plate 2. The limiting shaft 6 prevents the protective plate 2 from moving in the lateral direction and disconnects from the moving groove 4.
[0032] Slot 7 and locking block 8: The movement of the protective plate 2 is restricted by the cooperation of the locking block 8 and the slot 7. The operation is convenient and quick, and can meet the needs of installation and disassembly of the protective plate 2 in different working scenarios.
[0033] Screw 10 and nut 11: After the connection between nut 11 and screw 10 is released, pull the limiting shaft 6 so that the limiting shaft 6 drives the screw 10 to release the connection between the screw 10 and the moving groove 4 through the opening 12. At this time, the connection between the limiting shaft 6 and the mounting block 5 is released, and the protective plate 2 can be removed.
[0034] Spring 13: The elastic force of spring 13 is used to make the locking block 8 automatically move into the moving groove 4 when it is not pulled by external force, so as to fix the protective plate 2. At the same time, the elastic force of spring 13 can ensure the stability of the locking block 8 in fixing the protective plate 2.
[0035] Pull ring 15: It facilitates personnel to pull the locking block 8, overcomes the elastic force of the spring 13, and makes the locking block 8 disengage from the moving groove 4, thus improving the convenience of operation.
[0036] Working principle:
[0037] First, before the sheet metal bending device starts working, hold the pull ring 15 and pull the locking block 8 to disengage the locking block 8 from the inside of the moving groove 4. At this time, the spring 13 is stretched and pushes the protective plate 2 upward to block the bending mechanism. Release the pull ring 15, and under the action of the spring 13, the locking block 8 moves into the inside of the moving groove 4. At this time, the locking block 8 is located on the lower surface of the mounting block 5 to restrict the downward movement of the mounting block 5. At this time, the installation of the protective plate 2 is completed.
[0038] The second step is to hold the pull ring 15 and pull the locking block 8 to disengage the locking block 8 from the inside of the moving groove 4. At this time, the protective plate 2 moves downward under its own weight to expose the bending mechanism, and the bending mechanism can be repaired.
[0039] Finally, it should be noted that the above embodiments are merely examples for clearly illustrating the present invention and are not intended to limit the implementation. Those skilled in the art can make other variations or modifications based on the above description. It is neither necessary nor possible to exhaustively list all possible implementations. However, obvious variations or modifications derived therefrom are still within the protection scope of this invention.
