Description

Technical Field

[0001] This application relates to the technical field of bending machines, and in particular to a scrap collection device for CNC bending machines. Background Technology

[0002] CNC bending machines use equipped molds (general or special molds) to bend cold metal sheets into workpieces of various geometric cross-sectional shapes. One type of CNC bending machine mainly processes strip materials. Its main structure includes a worktable, a material transport structure installed on one side of the worktable, and a bending structure set on the worktable for bending the material.

[0003] In existing technologies, to prevent the bending structure from failing to bend the product, the transport structure is usually set to transport an extra distance after the total length of the product has been transported. This prevents the bending structure from failing to bend the product due to its own precision errors. However, this extra distance also results in a piece of scrap material remaining at the end of the product after bending, which requires further processing by the workers, which is very troublesome. To solve this problem, existing technologies install a cutting machine on the worktable, with a gap between the transport structure and the bending structure. The output end of the cutting machine is aligned with this gap. By setting the cutting machine, if scrap material appears at the end of the product, the cutting machine can be started to cut it, thus eliminating the need for further processing by the workers. However, the cut scrap material falls onto the worktable, and its accumulation over time will affect the transport of the transport structure. Therefore, a scrap material collection device for CNC bending machines is needed. Utility Model Content

[0004] To address the shortcomings of existing technologies, the purpose of this application is to provide a scrap collection device for CNC bending machines, which solves the transportation technology problem in the prior art where the accumulation of cut scraps affects the transportation structure.

[0005] The above-mentioned objective of this application is achieved through the following technical solution: a scrap collection device for a CNC bending machine, comprising a worktable, a transport structure installed on one side of the worktable for transporting materials, a bending structure set on the worktable for bending materials, and a cutting machine installed on the worktable for cutting materials. A gap is left between the transport structure and the bending structure, the output end of the cutting machine is aligned with the gap between the transport structure and the bending structure, and a collection structure for collecting scrap is provided at the gap between the transport structure and the bending structure.

[0006] Furthermore, the collection structure includes a connecting channel extending below the gap between the transport structure and the bending structure on one side of the workbench, a connecting port on the upper surface of the workbench and communicating with the connecting channel, and a collection box inserted into the connecting channel. The connecting port is located at the gap between the transport structure and the bending structure and fills the gap. The opening of the collection box faces the connecting port.

[0007] By adopting the above technical solution, after the cutting machine cuts the scrap, the scrap falls into the collection box through the connection port, thereby preventing the scrap from accumulating in the gap between the transport structure and the bending structure, and preventing the scrap from affecting the operation of the transport structure. Moreover, after the scrap in the collection box is full, the staff can pull out the collection box to collect the scrap inside. After collection, the collection box can be inserted into the connection channel for continued use. This solves the technical problem in the prior art that the accumulation of cut scrap will affect the transport structure, and makes it more convenient for staff to collect scrap.

[0008] Furthermore, the connecting channel is inclinedly opened inside the workbench, and the connecting channel is inclined downward from the inside out. The collection box is an inclined box body used to match the connecting channel. The connecting channel has limiting structures on both sides inside to prevent the collection box from sliding out of the connecting channel.

[0009] Furthermore, the limiting structure includes a compression rubber fixedly disposed on the inner wall of the connecting channel. The compression rubber is elastic and is distributed along the length of the connecting channel, covering the inner wall of the connecting channel.

[0010] While the above technical solution makes it easier for workers to collect scrap materials, during the operation of the bending machine, workers may easily overlook the situation inside the collection box. This can lead to the scrap materials overflowing the collection box and blocking the connection port after a period of time, affecting the transport device. The inclined connection channel and the compression rubber solve this problem. The inclined connection channel causes the collection box inserted into it to move downwards due to gravity. The compression rubber increases the friction between the collection box and the connection channel, preventing the collection box from easily falling out of the connection channel. After collecting a certain amount of scrap materials, the weight of the scrap materials and the weight of the collection box itself causes it to slide downwards against the compression rubber, partially detaching the collection box from the connection channel. This allows workers to easily observe whether the scrap materials inside the collection box are overflowing, enabling them to remove the scrap materials in time and preventing them from overflowing and blocking the connection port. Furthermore, the compression rubber can fill the gap between the collection box and the connection channel, preventing air from flowing into the workbench and oxidizing the components inside.

[0011] Furthermore, a limiting device is provided on one side of the connecting channel to prevent the collection box from sliding out of the connecting channel.

[0012] Furthermore, the limiting device includes a pressure sensor fixedly mounted on the bottom surface of the collection box, a support plate fixedly connected to the side of the workbench on one side of the connecting channel, a drive motor mounted on the support plate, and a limiting rod mounted on the output end of the drive motor. The limiting rod extends to the periphery of the output end of the drive motor, and the pressure sensor is electrically connected to the drive motor.

[0013] While the inclined connecting channel and the compression rubber allow workers to quickly retrieve scraps from the collection box, the varying impact force of each piece falling into the box causes some scraps to slip out even before it's full. This leads to misjudgment by workers, causing them to shut down the bending machine to retrieve the box. This necessitates restarting the machine and pushing the box back into the connecting channel, which is inconvenient. The limiting device solves this problem. Workers can then use the limit device to adjust the position of the scraps inside the collection box. When the scrap material in the collection box is about to overflow, the weight adjusts the threshold of the pressure sensor. In the initial state, the limit rod of the limit device blocks the collection box and restricts it within the connecting channel. When the scrap material in the collection box is about to overflow, its weight triggers the pressure sensor, which starts the drive motor. The drive motor rotates, so that the limit rod no longer blocks the collection box. Because of the rubber compression setting, the collection box will not suddenly slide out of the connecting channel, but will slide out of the connecting channel slowly. This way, when the staff sees this, they can judge that the scrap material in the collection box is about to overflow, allowing them to accurately extract the scrap material from the collection box and empty it in time.

[0014] Furthermore, a connection structure is provided between the limiting rod and the output end of the drive motor, and the limiting rod is installed on the output end of the drive motor through the connection structure.

[0015] Furthermore, the connection structure includes a sleeve fixedly connected to the output end of the drive motor, an inner groove opened in the middle of the sleeve, a collar sleeved in the inner groove, a limiting hole opened on the side wall of the inner groove, a receiving groove opened on the side of the limiting rod opposite to the limiting hole, a limiting plate placed in the receiving groove, a limiting post set at the lower end of the limiting plate directly opposite the limiting hole, and a support spring set in the receiving groove for pushing the limiting post into the limiting hole. The limiting plate is fixedly connected to the circumferential surface of the collar.

[0016] By adopting the above technical solution and through the setting of the connection structure, after the staff puts the collection box back into the connection channel, they only need to press the limit plate to make the limit post disengage from the limit hole, then rotate the limit rod to block the collection box and release the limit plate. The support spring pushes against the limit plate to make the limit post insert into the limit hole, which makes it more convenient for the staff to reset the limit device. Moreover, when the output end of the drive motor rotates, the limit rod can be driven to rotate through the sleeve.

[0017] In summary, this application includes at least one of the following beneficial technical effects:

[0018] By designing a collection structure, the scraps cut by the cutting machine fall into the collection box through the connection port, preventing them from accumulating in the gap between the transport and bending structures and affecting the operation of the transport structure. Furthermore, when the collection box overflows, workers can pull it out to collect the scraps. After collection, the collection box can be reconnected to the connection channel for continued use. This solves the technical problem in existing technologies where accumulated scraps can affect the transport structure, and also makes scrap collection more convenient for workers.

[0025] The present application will be further described in detail below with reference to the accompanying drawings.

[0026] Example, refer to Figure 1 , Figure 2 The scrap collection device for a CNC bending machine includes a worktable 1, a transport structure 10 installed on one side of the worktable 1 for transporting materials, a bending structure 11 installed on the worktable 1 for bending materials, and a cutting machine 12 installed on the worktable 1 for cutting materials. A gap exists between the transport structure 10 and the bending structure 11. The output end of the cutting machine 12 is aligned with the gap between the transport structure 10 and the bending structure 11. Notably, a scrap collection structure 2 is specifically provided at this gap between the transport structure 10 and the bending structure 11. This collection structure 2 consists of several parts. First, a connecting channel 20 extends from one side of the worktable 1 to below the gap, providing a channel for scrap collection. Second, connection ports communicating with the connecting channel 20 are opened on the upper surface of the worktable 1. These connection ports are distributed throughout the entire gap area, ensuring that scrap can fall smoothly.

[0027] Furthermore, a collection box 21 is inserted into the connecting channel 20, with the opening of the collection box 21 facing the connecting port. When the cutting machine 12 cuts the scrap, the waste material will immediately fall into the collection box 21 through the connecting port. This design not only effectively prevents the scrap from accumulating in the gap between the transport structure 10 and the bending structure 11, thus avoiding the impact of the scrap on the operation of the transport structure 10, but also makes the collection of scrap extremely convenient.

[0028] When the scrap material in the collection box 21 reaches its overflowing state, the staff can easily pull out the collection box 21 to recycle the scrap material. After recycling, the collection box 21 can be inserted back into the connecting channel 20 for continued use. This process is not only efficient but also greatly reduces the labor intensity of the staff, making the recycling and processing of scrap material more convenient and faster.

[0029] In summary, the collection structure 2 not only solves the technical problem that the accumulation of cut scraps in the prior art affects the transportation of the transport structure 10, but also makes the collection and processing of scraps simpler and more efficient through its ingenious design, bringing great convenience to the use of CNC bending machines.

[0030] Although the collection structure 2 makes it easier for workers to collect scrap materials, during the operation of the bending machine, workers can easily overlook the situation inside the collection box 21. This causes the scrap materials inside the collection box 21 to overflow and block the connection port after a period of time, affecting the subsequent transport device. To solve this technical problem, in this embodiment, the connection channel 20 is inclined inside the workbench 1, and the connection channel 20 is inclined downward from the inside out. The collection box 21 is an inclined box body to match the connection channel 20. The inside of the connection channel 20 is provided with limiting structures on both sides to prevent the collection box 21 from sliding out of the connection channel 20. The limiting structures include compression rubber 3 fixedly installed on the inner wall of the connection channel 20. The compression rubber 3 is elastic and is distributed along the length of the connection channel 20 to cover the inner wall of the connection channel 20. The inclined connection channel 20... The pressure of the rubber 3 causes the collection box 21, which is inserted into the connecting channel 20, to move downwards due to gravity. The pressure of the rubber 3 increases the friction between the collection box 21 and the connecting channel 20, preventing the collection box 21 from easily falling out of the connecting channel 20. After a certain amount of scrap is collected inside the collection box 21, the weight of the scrap and the weight of the collection box 21 itself causes the collection box 21 to slide downwards against the pressure of the rubber 3, thus causing the collection box 21 to partially detach from the connecting channel 20. This allows the operator to easily observe whether the scrap inside the collection box 21 has overflowed, enabling the operator to remove the scrap in time, thereby preventing the scrap from overflowing and blocking the connection port. In addition, the pressure of the rubber 3 can also fill the gap between the collection box 21 and the connecting channel 20, preventing air from flowing into the workbench 1 and oxidizing the components inside the workbench 1.

[0031] Although the inclined connecting channel 20 and the compression rubber 3 allow workers to promptly retrieve scrap materials from the collection box 21, the varying impact force of each piece falling into the box causes some scrap materials to slip out of the connecting channel 20 even when the box is not full. This leads to misjudgment by workers, causing them to shut down the bending machine to retrieve the collection box 21. This necessitates restarting the bending machine and pushing the collection box 21 back into the connecting channel 20, which is very inconvenient. To solve this technical problem, [the following text is missing from the original] Figure 3 , Figure 4 as well as Figure 5In this embodiment, a limiting device 4 is provided on one side of the connecting channel 20 to prevent the collection box 21 from sliding out of the connecting channel 20. The limiting device 4 includes a pressure sensor 40 fixedly installed on the bottom surface of the collection box 21, a support plate 41 fixedly connected to the side of the workbench 1 on one side of the connecting channel 20, a drive motor 42 installed on the support plate 41, and a limiting rod 43 installed on the output end of the drive motor 42. The limiting rod 43 extends to the periphery of the output end of the drive motor 42. The pressure sensor 40 is electrically connected to the drive motor 42. The operator adjusts the threshold of the pressure sensor 40 according to the weight of the scrap material in the collection box 21 when it is almost overflowing. In the initial state, the limiting rod 43 of the positioning device 4 blocks the collection box 21 and restricts it within the connecting channel 20. When the scrap material in the collection box 21 is about to overflow, its weight triggers the pressure sensor 40, which starts the drive motor 42. The drive motor 42 rotates, so that the limiting rod 43 no longer blocks the collection box 21. Because of the setting of the squeezing rubber 3, the collection box 21 will not suddenly slide out of the connecting channel 20, but will slowly slide out of the connecting channel 20. When the staff sees this, they can judge that the scrap material in the collection box 21 is about to overflow, so that the staff can accurately extract the scrap material in the collection box 21 and empty the collection box 21 in time.

[0032] In this embodiment, a connection structure 5 is provided between the limiting rod 43 and the output end of the drive motor 42. The limiting rod 43 is installed on the output end of the drive motor 42 through the connection structure 5. The connection structure 5 includes a sleeve 50 fixedly connected to the output end of the drive motor 42, an inner groove opened in the middle of the sleeve 50, a collar 51 sleeved in the inner groove, a limiting hole 52 opened on the side wall of the inner groove, a receiving groove 53 opened on the side of the limiting rod 43 opposite to the limiting hole 52, a limiting plate 54 placed in the receiving groove 53, a limiting post 55 set at the lower end of the limiting plate 54 facing the limiting hole 52, and a support spring 5 set in the receiving groove 53 for pushing the limiting post 55 into the limiting hole 52. 6. The limiting plate 54 is fixedly connected to the circumference of the collar 51. With the setting of the connecting structure 5, after the worker inserts the collection box 21 back into the connecting channel 20, he only needs to press the limiting plate 54 to make the limiting post 55 disengage from the limiting hole 52, then rotate the limiting rod 43 to block the collection box 21 and then release the limiting plate 54. The support spring 56 pushes against the limiting plate 54 to make the limiting post 55 insert into the limiting hole 52, which makes it more convenient for the worker to reset the limiting device 4. When the output end of the drive motor 42 rotates, it can drive the limiting rod 43 to rotate through the sleeve 50. There are multiple limiting holes 52 in a ring array with the axis of the sleeve 50 as the base point, which makes it easy for the limiting post 55 to be inserted into the limiting hole 52.

[0033] Specific implementation process: After the cutting machine 12 cuts the scrap, the scrap falls into the collection box 21 through the connection port, thereby preventing the scrap from accumulating in the gap between the transport structure 10 and the bending structure 11, and preventing the scrap from affecting the operation of the transport structure 10. When the scrap in the collection box 21 is about to overflow, the weight of the scrap triggers the pressure sensor 40, and the pressure sensor 40 starts the drive motor 42. The drive motor 42 rotates, so that the limit rod 43 no longer blocks the collection box 21. Because of the setting of the squeezing rubber 3, the collection box 21 will not suddenly slide out of the connection channel 20, but slowly slide out of the connection channel 20. When the staff sees this, they can judge that the scrap in the collection box 21 is about to overflow, so that the staff can accurately extract the scrap in the collection box 21 and empty the collection box 21 in time.

[0034] The embodiments described in this specific implementation are preferred embodiments of this application and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
