Description

Technical Field

[0001] This utility model relates to the field of bending machine technology, specifically a bending machine with debris removal function. Background Technology

[0002] In the field of metal processing, bending machines are key equipment for shaping metal sheets, widely used in many industries such as automobile manufacturing, aerospace, and electronic equipment production. With the continuous development of the manufacturing industry, the requirements for metal processing precision and efficiency are increasing. Some problems in the actual operation of bending machines are gradually becoming apparent. During the bending process, metal sheets are subjected to strong external forces, causing plastic deformation of the sheet's internal structure and inevitably producing debris. These debris vary in shape and size, ranging from powder to flakes or blocks. In the working environment of traditional bending machines, this debris is often not cleaned up in a timely and effective manner, accumulating in large quantities on the worktable. When performing the next bending operation, the accumulated debris interferes with the precise positioning of the sheet, leading to deviations in the dimensions of the bent product from design requirements, seriously affecting product accuracy and increasing the defect rate.

[0003] According to the patent application published on the Internet, a bending machine with debris cleaning function (authorization announcement number: CN222519603U) includes "fixed plate, moving parts, rotating parts" to achieve the cleaning work.

[0004] Regarding the above description, the applicant believes the following issues exist:

[0005] This bending machine with debris cleaning function uses a fixed plate, moving parts, and rotating parts to perform the cleaning work. During use, the cleaning plate cleans the debris in the bending groove. However, debris also adheres to the bending head on the machine body during use. This bending machine cannot clean the debris on the bending head, and cleaning the debris with the cleaning plate results in incomplete cleaning, affecting the cleaning effect. Furthermore, it cannot collect the cleaned debris. Therefore, this bending machine needs to be improved. Utility Model Content

[0006] The purpose of this invention is to provide a bending machine with debris removal capabilities to solve the problems mentioned in the background section.

[0007] To achieve the above objectives, the present invention provides the following technical solution: a bending machine with debris cleaning function, comprising a support platform, a cleaning mechanism on the top of the support platform, and a bending mechanism on the top of the cleaning mechanism;

[0008] The cleaning mechanism includes a processing table, which is fixedly connected to the top of a support platform. A bending table is fixedly connected to the top of the processing table. Extension frames are fixedly connected to the front and rear sides of the bending table. A fixed frame is fixedly connected to the bottom of the processing table. A servo motor is fixedly connected to the right side of the fixed frame. A threaded rod is fixedly connected to the left side of the servo motor. A load-bearing frame is threadedly connected to the outer periphery of the threaded rod. The load-bearing frame is slidably connected to the inside of the processing table. A mounting base is fixedly connected to the bottom of the inner side of the load-bearing frame. A first cleaning brush is fixedly connected to the outer periphery of the mounting base and is located inside the bending table. A mounting bracket is fixedly connected to the left side of the load-bearing frame. A second cleaning brush is fixedly connected to the inner side of the mounting bracket and is located at the bottom of the bending mechanism. A base is fixedly connected to the left side of the bottom of the processing table. A storage box is fixedly connected to the top of the base. A sealing door is rotatably connected to the left side of the storage box. A conveyor frame is fixedly connected to the right side of the storage box.

[0009] Preferably, the processing table has a sliding groove inside, and the inner side of the load-bearing frame is slidably connected to the sliding groove, so that the load-bearing frame can move more stably under the action of the sliding groove.

[0010] Preferably, the outer periphery of the first cleaning brush is in contact with the inner side of the bending table, and both the first and second cleaning brushes are made of ceramic fiber material, which facilitates the cleaning of debris generated on the inner side of the bending table under the action of the first cleaning brush after bending.

[0011] Preferably, the threaded rod is rotatably connected to the fixed frame on the left side, and the conveying frame is fixedly connected to the left side of the bending table, so that the load-bearing frame can be moved under the action of the threaded rod.

[0012] Preferably, the fixed frame has a movable groove inside, and the load-bearing frame is slidably connected to the movable groove, so as to further ensure the balance and stability of the movement of the load-bearing frame under the action of the movable groove.

[0013] Preferably, the bending mechanism includes a fixed platform, which is fixedly connected to the rear side of the top of the processing table. A hydraulic cylinder is fixedly connected to the top of the fixed platform, and a bending head is fixedly connected to the bottom of the hydraulic cylinder. The bending head is slidably connected to the inside of the bending table, and a fixing rod is fixedly connected to the top of the bending head. The fixing rod is slidably connected to the inside of the fixed platform.

[0014] Preferably, the bottom periphery of the bending head is in contact with the inner side of the second cleaning brush. Two sets of fixing rods are provided, and the two sets of fixing rods are symmetrically located on the top of the bending head, which facilitates the cleaning of debris adhering to the bottom periphery of the bending head due to bending under the action of the second cleaning brush, ensuring the quality of subsequent bending.

[0015] Compared with the prior art, this utility model provides a bending machine with debris removal, which has the following beneficial effects:

[0016] This bending machine with debris removal mechanism, through its cleaning system, allows for bending of sheet metal. The sheet metal is placed on the bending table and the top of the extension frame, and the bending head is engaged to perform the bending operation. The size of the sheet metal must not exceed the outer perimeter of the extension frame. After bending, the sheet metal is removed, and the bending head is moved upwards a certain distance until its bottom outer perimeter contacts the inner side of the second cleaning brush. A servo motor drives the threaded rod to rotate, causing the support frame to move horizontally within the processing table, bringing the outer perimeter of the first cleaning brush into contact with the inner side of the bending table. The inner side of the second cleaning brush contacts the outer periphery of the bottom of the bending head, cleaning the inner side of the bending table and the bottom of the bending head from all angles. This effectively removes debris generated during processing, preventing debris accumulation from affecting bending accuracy. After cleaning, the debris is conveyed to the storage box by the conveyor frame under the action of the first and second cleaning brushes. The second cleaning brush is located to the left of the first cleaning brush. When the second cleaning brush cleans the debris on the outer periphery of the bottom of the bending head, the debris falls onto the inner side of the bending table and continues to be cleaned by the first cleaning brush, ensuring the cleaning effect.

[0017] This bending machine with debris removal mechanism, through its bending mechanism, allows the bending head to slowly descend when the sheet metal to be bent is placed on the bending table and the extension frame, with the part to be bent at the top of the bending table. Before the bending head contacts the sheet metal, external fixing equipment can press the sheet metal until the bending head contacts the sheet metal, at which point the pressing is released. When the bending head contacts the sheet metal, the sheet metal can be bent under the action of the bending table. During the movement of the bending head, the fixing rod will move, further ensuring the balance of the bending head movement and the bending quality. Attached Figure Description

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0027] In this utility model, unless otherwise explicitly specified and limited, the terms "installation," "connection," "joining," and "fixing," etc., should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances.

[0028] This utility model provides the following technical solution: Example 1

[0029] Please see Figure 1-6 This utility model provides a technical solution: a bending machine with debris cleaning function, including a support platform 1, a cleaning mechanism 2 on the top of the support platform 1, and a bending mechanism 3 on the top of the cleaning mechanism 2;

[0030] Cleaning mechanism 2 includes a processing table 21, which is fixedly connected to the top of support platform 1. A bending table 24 is fixedly connected to the top of processing table 21. Extension frames 25 are fixedly connected to the front and rear sides of bending table 24. A fixed frame 22 is fixedly connected to the bottom of processing table 21. A servo motor 23 is fixedly connected to the right side of fixed frame 22. A threaded rod 291 is fixedly connected to the left side of servo motor 23. A load-bearing frame 292 is threadedly connected to the outer periphery of threaded rod 291. The load-bearing frame 292 is slidably connected to the inside of processing table 21. A load-bearing frame 292 is fixedly connected to the bottom of the inner side of the load-bearing frame 292. Mounting base 293, with a first cleaning brush 294 fixedly connected to its periphery. The first cleaning brush 294 is located inside the bending table 24. Mounting frame 295 is fixedly connected to the left side of the load-bearing frame 292. A second cleaning brush 296 is fixedly connected to the inner side of the mounting frame 295. The second cleaning brush 296 is located at the bottom of the bending mechanism 3. Base 29 is fixedly connected to the bottom left side of the processing table 21. Storage box 27 is fixedly connected to the top of the base 29. Sealing door 28 is rotatably connected to the left side of storage box 27. Conveyor frame 26 is fixedly connected to the right side of storage box 27.

[0031] The processing table 21 has a sliding groove inside, and the inner side of the load-bearing frame 292 is slidably connected in the sliding groove, which makes the movement of the load-bearing frame 292 more stable under the action of the sliding groove. The outer side of the first cleaning brush 294 is in contact with the inner side of the bending table 24, and both the first cleaning brush 294 and the second cleaning brush 296 are made of ceramic fiber material, which makes it easy to clean the debris generated on the inner side of the bending table 24 under the action of the first cleaning brush 294 after bending.

[0032] The threaded rod 291 is rotatably connected to the fixed frame 22 on the left side, and the conveying frame 26 is fixedly connected to the left side of the bending table 24, so that the load-bearing frame 292 can be moved under the action of the threaded rod 291. The fixed frame 22 has a moving groove inside, and the load-bearing frame 292 is slidably connected to the moving groove, so that the balance and stability of the movement of the load-bearing frame 292 can be further ensured under the action of the moving groove. Example 2

[0033] Please see Figure 1-6 Furthermore, based on Embodiment 1, the bending mechanism 3 further includes a fixed platform 31, which is fixedly connected to the rear top of the processing table 21. A hydraulic cylinder 32 is fixedly connected to the top of the fixed platform 31, and a bending head 34 is fixedly connected to the bottom of the hydraulic cylinder 32. The bending head 34 is slidably connected to the inner side of the bending table 24, and a fixed rod 33 is fixedly connected to the top of the bending head 34. The fixed rod 33 is slidably connected to the inside of the fixed platform 31. The outer periphery of the bottom of the bending head 34 is in contact with the inner side of the second cleaning brush 296. Two sets of fixed rods 33 are provided, and the two sets of fixed rods 33 are symmetrically located on the top of the bending head 34, which facilitates the cleaning of debris attached to the outer periphery of the bottom of the bending head 34 due to bending under the action of the second cleaning brush 296, ensuring the quality of subsequent bending.

[0034] In actual operation, when this device is used, when the sheet material to be bent is placed on the top of the bending table 24 and the extension frame 25, and the part to be bent is on the top of the bending table 24, the bending head 34 can be slowly lowered by the hydraulic cylinder 32. When the bending head 34 is not in contact with the sheet material, the sheet material can be pressed by the external fixing device until the bending head 34 contacts the sheet material, at which point the pressing can be released. When the bending head 34 contacts the sheet material, the sheet material can be bent under the action of the bending table 24. During the movement of the bending head 34, the fixing rod 33 will move, further ensuring the balance of the movement of the bending head 34 and the bending quality.

[0035] After the bending operation is completed, the sheet metal is removed. Under the action of the hydraulic cylinder 32, the bending head 34 can be moved upward a certain distance until the bottom outer edge of the bending head 34 contacts the inner side of the second cleaning brush 296. At this time, the outer edge of the first cleaning brush 294 contacts the inner side of the bending table 24, and the inner side of the second cleaning brush 296 contacts the bottom outer edge of the bending head 34. The inner side of the bending table 24 and the bottom of the bending head 34 are cleaned in all directions. This can remove the debris generated during the processing in time and avoid the accumulation of debris affecting the bending accuracy. The cleaned debris will be transported to the storage box 27 for storage through the conveyor frame 26 under the action of the first cleaning brush 294 and the second cleaning brush 296.

[0036] Furthermore, the second cleaning brush 296 is located to the left of the first cleaning brush 294. When the second cleaning brush 296 cleans the debris on the outer periphery of the bottom of the bending head 34, the debris will fall onto the inner side of the bending table 24 and continue to be cleaned under the action of the first cleaning brush 294, ensuring the cleaning effect. This allows for simultaneous cleaning of the inner side of the bending table 24 and the outer periphery of the bottom of the bending head 34, improving the cleaning effect.

[0037] The first cleaning brush 294 and the second cleaning brush 296 are made of ceramic fiber material. The cleaning brush made of ceramic fiber can withstand friction and scouring at high temperature. At the same time, the surface of ceramic fiber has a certain roughness, which is not conducive to the adhesion of iron filings. The adhesion between iron filings and ceramic fiber is weak. Moreover, ceramic fiber itself is not magnetic and will not have an adsorption effect on iron filings like some metal materials.

[0038] In this case, the bending technology is a structure and usage procedure known to those skilled in the art and is not the focus of this case. This case does not describe the bending process in detail. Furthermore, during use, the servo motor 23 and the hydraulic cylinder 32 can be connected to the same PLC control system to ensure coordinated operation between the devices.

[0039] It should be noted that, in this document, relational terms such as "first" and "second" are used only to distinguish one entity or operation from another, and do not necessarily require or imply any such actual relationship or order between these entities or operations. Furthermore, the terms "comprising," "including," or any other variations thereof are intended to cover non-exclusive inclusion, such that a process, method, article, or apparatus that comprises a list of elements includes not only those elements but also other elements not expressly listed, or elements inherent to such a process, method, article, or apparatus. Without further limitations, an element defined by the phrase "comprising one..." does not exclude the presence of other identical elements in the process, method, article, or apparatus that includes said element.
