In the operation of a numerical control bending machine, positioning is a crucial step, which ensures that the workpiece can be accurately placed on the workbench of the machine tool and aligned with the reference point or working point of the workbench to ensure processing accuracy and consistency.

[0003] After long-term use of the existing quick magnetic adsorption processing and positioning device for long strip workpieces of a bending machine, a large amount of metal debris and dust splashed when the bending machine bends the workpiece will accumulate in its gaps, which will affect the magnetic force intensity of the device. However, the device does not have a cleaning mechanism, and manual cleaning is still required later with low efficiency, resulting in a low practicality of the device.

[0009] Preferably, an extension plate is fixedly installed at the bottom of the machine body.

One end of the output shaft of the rotating motor is coaxially and fixedly connected with a second spur gear, and the second spur gear meshes with the first spur gear.

[0010] Preferably, the connecting frame is rotatably connected with a rotating block. The rotating block is attached with a limiting block, and one end of the limiting block penetrates through the rotating block. One end of the limiting block is rotatably connected with a cleaning brush.

[0013] Preferably, the number of the screwing parts is two.

[0014] Compared with the prior art, the utility model has the following beneficial effects:

[0015] 1. For the quick magnetic adsorption processing and positioning device of long strip workpieces of the bending machine, through the arrangement of the cleaning component, during use, the rotating plate is driven to rotate by the action of an external power source. During the rotation process, since both ends of the connecting arm rod are rotatably connected with the rotating plate and the connecting shaft respectively, the rotational movement of the rotating plate will be converted into their contraction actions through the connecting arm rod. As the connecting arm rod contracts, the two connecting shafts will approach each other, and at the same time drive the sliding blocks on their tops to move along the preset track on the inner wall of the machine body towards the central position of the machine body. During this process, the sliding blocks not only move along the track, but also they carry the cleaning brushes. Therefore, as the sliding blocks move, the cleaning brushes will also move simultaneously. Since the cleaning brushes are installed at both ends of the machine body, their moving paths can just cover the gap areas on the top of the machine body, so as to realize the cleaning of the metal debris and dust accumulated therein.

[0016] 2. The quick magnetic adsorption processing and positioning device for long workpieces of the bending machine, through the setting of the collection component, when in use, when the cleaning brush cleans the metal chips and dust accumulated in the gaps at the top of the machine body, the rotating motor started simultaneously drives the second spur gear fixedly connected coaxially with its output shaft to rotate. The rotation of the second spur gear will cause a linkage with the two first spur gears meshing with it, causing the first spur gears to also start rotating. Since the first spur gear is fixedly connected coaxially with the rotating shaft, the rotating shaft will rotate with the rotation of the first spur gear. As the rotating shaft rotates, the fan blades installed at one end of it start to rotate. The rotation of the fan blades will generate suction inside the fixed frame, forming a local air flow. The function of this air flow is to attract and guide the metal chips and dust swept to the center of the machine body by the cleaning brush through the notch at the top of the machine body where the fixed frame is located into the fixed frame. Once the metal chips and dust are sucked into the fixed frame, they will fall into the collection frame below due to the action of gravity. The collection frame is designed to accommodate these cleaned metal chips and dust, facilitating subsequent unified collection and processing. BRIEF DESCRIPTION OF THE DRAWINGS

One end of the sliding block 2 is fixedly connected with a connecting frame 3. A cleaning brush 4 is arranged on the inner wall of the connecting frame 3. One end of the cleaning brush 4 is provided with another connecting frame 3. The other connecting frame 3 is slidably connected with the machine body 1. Through this automatic cleaning process, the gap area on the top of the machine body 1 is kept clean, thus ensuring the accuracy of processing and positioning and the long-term stable operation of the equipment.

[0025] Among them; a fixed frame 6 is fixedly installed at the bottom of the machine body 1. A grid partition plate 11 is fixedly installed inside the fixed frame 6. Both sides of one end of the fixed frame 6 are rotatably connected with rotating shafts 8. Both rotating shafts 8 are coaxially fixedly connected with a first spur gear 9. One end of both rotating shafts 8 is fixedly installed with a fan blade 10. A collection box 7 is arranged inside the fixed frame 6. A filter screen 12 is fixedly installed at one end of the collection box 7. The filter screen 12 can effectively prevent the metal debris and dust collected in the collection box 7 from passing through the grid partition plate 11, thereby causing damage to the first spur gear and the second spur gear.

[0026] Among them; a rotating plate 13 is rotatably connected to the bottom of the fixed frame 6. Both ends of the rotating plate 13 are rotatably connected with connecting arm rods 14. One end of the connecting arm rod 14 is rotatably connected with a connecting shaft 15. One end of the connecting shaft 15 is fixedly connected with the connecting plate 5.

[0027] Among them; an extension plate 16 is fixedly installed at the bottom of the machine body 1. The extension plate 16 is fixedly connected with a rotating motor 17. And the output shaft of the rotating motor 17 penetrates through one end of the fixed frame 6. One end of the output shaft of the rotating motor 17 is coaxially fixedly connected with a second spur gear 18. The second spur gear 18 meshes with the first spur gear 9.

[0028] Among them; a rotating block 19 is rotatably connected to the connecting frame 3. The rotating block 19 fits with a limiting block 22. And one end of the limiting block 22 penetrates through the rotating block 19. One end of the limiting block 22 is rotatably connected with the cleaning brush 4.

[0029] Among them; an electromagnetic chuck 20 is arranged on the top of the machine body 1. The machine body 1 is fixedly connected with a screw connection member 21.

[0030] Among them; the material of the bristles of the cleaning brush 4 is nylon.

[0031] Among them, the number of the screwed parts 21 is two.

[0032] Working principle: When in use and when the device needs to be cleaned, first, the external power source drives the rotating plate 13 to start rotating. During the rotation, since both ends of the connecting arm rod 14 are rotatably connected to the rotating plate 13 and the connecting shaft 15 respectively, the rotational movement of the rotating plate 13 will be converted into their contraction actions through the connecting arm rod 14. As the connecting arm rod 14 contracts, the two connecting shafts 15 will move closer to each other, and at the same time drive the sliding blocks 2 on their tops to move along the preset track on the inner wall of the machine body 1 towards the central position of the machine body. During this process, the sliding blocks 2 not only move along the track, but also they carry the cleaning brushes 4. Therefore, as the sliding blocks 2 move, the cleaning brushes 4 will also move simultaneously. Since the cleaning brushes 4 are installed at both ends of the machine body 1, their moving paths can just cover the gap area at the top of the machine body 1, so as to clean the metal debris and dust accumulated therein and sweep them to the center of the machine body 1. At the same time, when the cleaning brushes 4 clean the metal debris and dust accumulated in the gaps at the top of the machine body 1, the rotating motor 17 started simultaneously drives the spur gear two 18 fixedly connected coaxially with its output shaft to rotate through its output shaft. The rotation of the spur gear two 18 will generate a linkage with the two spur gears one 9 meshing with it, so that the spur gears one 9 also start to rotate. Since the spur gears one 9 are fixedly connected coaxially with the rotating shaft 8, the rotating shaft 8 will rotate with the rotation of the spur gears one 9. As the rotating shaft 8 rotates, the fan blades 10 installed at one end of it start to rotate. The rotation of the fan blades 10 will generate a suction force inside the fixed frame 6, forming a local air flow. The function of this air flow is to attract and guide the metal debris and dust swept to the center of the machine body 1 by the cleaning brushes 4 through the notch at the top of the machine body 1 where the fixed frame 6 is located into the fixed frame 6. Once the metal debris and dust are sucked into the fixed frame 6, they will fall into the collection box 7 below due to the action of gravity. The collection box 7 is designed to accommodate these cleaned metal debris and dust, which is convenient for subsequent unified collection and processing.
