Description

Technical Field

[0001] This utility model relates to the field of CNC bending machine technology, specifically an automatic feeding CNC bending machine. Background Technology

[0002] A CNC bending machine is a machine that uses a digital control system to perform precise bending. It is commonly used for processing metal sheets and is suitable for bending metal sheets of various shapes and sizes. Its applications are wide-ranging, including the automotive manufacturing, aerospace, and construction industries. Compared with traditional bending machines, CNC bending machines are easier to operate, have higher production efficiency, and can effectively reduce human error.

[0003] Patent CN217044096U discloses a CNC synchronous bending machine, including a base plate assembly, support legs, columns, an electrical control cabinet, a PLC controller, and a bending assembly. In this invention, the base plate assembly places the sheet metal on the support plate. The PLC controller controls the telescopic rod to operate, pushing the push plate towards the sheet metal, causing the push plate to contact the sheet metal. The push plate then quickly aligns the bending position of the sheet metal with the bending groove, improving the bending machine's efficiency. The bending assembly, controlled by the PLC controller, pushes the mounting plate and bending plate downwards. The bending plate and bending groove work together to bend the sheet metal placed on the support plate. The structure is simple, operation is convenient and quick, facilitating market promotion and application. The PLC controller, when powered on, controls the telescopic rod and the press to perform the alignment and bending of the sheet metal, achieving automated control and improving the machine's intelligence.

[0004] Based on existing solutions and actual use, current CNC bending machines still have some problems. For example, when bending materials, workers need to feed the materials into the bending machine one by one. During manual feeding, the material placement is inaccurate, which affects the final bending accuracy. Because of manual feeding, the material may slip or shift during the bending process, resulting in deviations in bending angle and position, thus affecting the product processing accuracy. Utility Model Content

[0005] The purpose of this utility model is to provide an automatic feeding CNC bending machine to solve the problems mentioned in the background art, which currently require manual feeding of materials one by one into the bending machine, resulting in inaccurate material placement and affecting the final bending accuracy. At the same time, manual feeding causes material slippage or displacement during the bending process, leading to deviations in bending angle and position.

[0006] To achieve the above objectives, this utility model provides the following technical solution: an automatic feeding CNC bending machine, comprising:

[0007] The base has a bending machine body fixedly installed at its rear end.

A placement platform is slidably connected to the top of the base, and the front end of the placement platform is fixedly connected to the rear end of the connecting rods. The placement platform is provided with a fixing component, and an adjustment component is provided at the rear end of the placement platform.

[0008] Preferably, the conveying assembly includes a connecting block, a synchronous pulley, a belt, and a motor. The connecting block is slidably connected to the side wall of the conveying trough. The synchronous pulleys are rotatably connected to both the front and rear ends inside the conveying trough. The front synchronous pulley and the rear synchronous pulley in the conveying trough are connected together by a belt sleeve. The motor is fixedly installed on the side wall of the conveying trough, and the output end of the motor is fixedly connected to the shaft of the front synchronous pulley in the conveying trough.

[0009] Preferably, the connecting block is fixedly connected to the belt body of the lower conveyor belt in the conveyor trough, and the connecting block is fixedly connected to the sliding plate.

[0010] Preferably, the fixing assembly includes a fixing clamp, a rotating rod, a hinge rod, a guide plate, and an electric push rod. The fixing clamp is slidably connected to both the left and right ends of the top of the placement platform. The rotating rod is rotatably connected to the middle position inside the placement platform, and the left and right ends of the rotating rod are rotatably connected to the hinge rod. The left and right ends of the placement platform are slidably connected to the guide plate. The front and rear ends of the placement platform are fixedly installed with electric push rods, and the output end of the electric push rod is fixedly connected to the right end of the left guide plate in the placement platform.

[0011] Preferably, both the front and rear ends of the bottom of the fixing clamp extend through into the interior of the placement platform, and the end of the fixing clamp located inside the placement platform is fixedly connected to the guide plate. The side wall of the guide plate is rotatably connected to the hinge rod, and the hinge rod and the rotating rod are arranged in a "Z" shaped structure.

The rear end of the sliding rod is fixedly installed with the support plate, and the support plate is set in a corresponding state with the bending machine body. The left and right ends of the top of the placement platform are slidably connected to the bolts, and the bolts are inserted into the through holes on the sliding rod.

[0013] Preferably, the rear end of the top of the placement platform is provided with two sets of sliding grooves, and the rear end of the bottom of the placement platform is provided with threaded holes in an array. The threaded holes at the rear end of the placement platform are arranged symmetrically about the vertical central axis of the placement platform. The threaded holes at the rear end of the placement platform are arranged in a corresponding state with the through holes on the sliding rod body, and the threaded holes at the rear end of the placement platform are connected together with bolts.

[0014] Compared with the prior art, the beneficial effects of this utility model are as follows: This automatic feeding CNC bending machine can automatically transport materials through the sliding of the placement table and ensure the stability of the materials during the processing. This not only reduces manual intervention but also reduces the impact of human factors on bending accuracy. The fixed clamp can fix the materials, which can effectively prevent the materials from slipping or moving during the processing and avoid deviations in bending angle and position due to material movement. At the same time, by adjusting the distance between the support plate and the placement table, it can adapt to various bending angles and material thicknesses, thereby meeting diverse bending needs.

[0015] 1. The conveying trough, connecting block, synchronous pulley, belt, motor, sliding plate, connecting rod, and placement table are connected by a belt sleeve between the front and rear synchronous pulleys in the conveying trough. The output end of the motor is fixedly connected to the shaft of the front synchronous pulley in the conveying trough, thereby driving the belt to rotate. The connecting block is fixedly connected to the belt body and the sliding plate respectively. The forward and reverse rotation of the motor can adjust the connecting block to slide back and forth on the side wall of the conveying trough. The sliding plate is fixedly connected to the placement table by the connecting rod. The sliding of the connecting block causes the sliding plate and the placement table to slide on the top of the base, thereby conveying the material to the bending point of the bending machine body. The sliding of the placement table can automatically convey the material, reduce manual intervention, ensure the stability of the material during processing, reduce the impact of human factors on bending accuracy, and thus ensure consistent bending results.

[0016] 2. The device is equipped with a placement platform, a fixed clamping plate, a rotating rod, a hinge rod, a guide plate, and an electric push rod. The output end of the electric push rod is fixedly connected to the right end of the left guide plate in the placement platform. The rotating rod and the hinge rod are combined to form a "Z" shape. The side wall of the guide plate is rotatably connected to the hinge rod, and the guide plate is fixedly connected to the fixed clamping plate located inside the placement platform. By operating the electric push rod, the fixed clamping plate can be driven to slide in the opposite direction through the cooperation between the rotating rod and the hinge rod. The sliding of the fixed clamping plate can fix the material, effectively preventing the material from slipping or moving during processing. This avoids bending angle and position deviations caused by material movement, thereby improving processing stability.

[0017] 3. The system includes a placement platform, a sliding rod, a support plate, and bolts. The support plate is fixedly installed on the rear end of the sliding rod, which is slidably connected to the rear end of the placement platform. The sliding rod has a through hole that corresponds to a threaded hole at the bottom rear end of the placement platform, and the bolts are also inserted into the through hole of the sliding rod. This allows the bolts to slide on the placement platform, and the bolts, through the sliding rod, cause the support plate to extend and retract. Tightening the bolts in the through hole connects them to the threaded hole in the placement platform, thus fixing the position of the support plate. Adjusting the support plate allows for adjustment of the gap between it and the placement platform, accommodating various bending angles and material thicknesses. Adjusting the support plate also ensures a consistent bending effect, meeting diverse bending requirements. Attached Figure Description

[0028] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. 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.

[0029] Please see Figure 1-9 This utility model provides a technical solution: an automatic feeding CNC bending machine, comprising: a base 1, a bending machine body 2, a conveying groove 3, a connecting block 4, a synchronous pulley 5, a belt 6, a motor 7, a sliding plate 8, a connecting rod 9, a placement table 10, a fixed clamping plate 11, a rotating rod 12, a hinge rod 13, a guide plate 14, an electric push rod 15, a sliding rod 16, a support plate 17, and bolts 18.

[0030] Example 1; First, as shown in the attached document... Figure 3 Appendix Figure 4 Appendix Figure 7 Appendix Figure 8 and attached Figure 9 As shown, when the sheet metal is bent by the bending machine body 2, the distance between the support plate 17 and the placement platform 10 is first adjusted according to the actual bending requirements. Since the placement platform 10 is slidably connected to the top of the base 1, sliding rods 16 are slidably connected to both the left and right ends of the rear end of the placement platform 10, and the rear end of the sliding rod 16 is fixedly connected to the support plate 17. At the same time, bolts 18 are slidably connected to both the left and right ends of the top of the placement platform 10. Through holes are opened on the rod body of the sliding rod 16, and the rod body of the bolt 18 is inserted into the through holes on the rod body of the sliding rod 16. Thus, the support plate 17 is pulled according to the actual situation, thereby moving the placement platform 10 and the support plate 17 together. After adjusting the spacing between the plates 17 to a suitable position, threaded holes are arrayed at the rear end of the bottom of the placement platform 10, and the threaded holes at the bottom of the placement platform 10 correspond to the through holes on the sliding rod 16. After adjusting the spacing between the placement platform 10 and the support plate 17, the bolt 18 is rotated to connect the bolt 18 with the threaded holes at the bottom of the placement platform 10, thereby fixing the sliding rod 16 and the position of the support plate 17. This adjusts the spacing between the support plate 17 and the placement platform 10 to a suitable level, allowing for the adaptation to various bending angles and material thicknesses. The adjustment of the support plate 17 can ensure a consistent bending effect.

[0031] Example 2; as attached Figure 1 Appendix Figure 2 Appendix Figure 3 Appendix Figure 4 Appendix Figure 5 Appendix Figure 6 and attached Figure 7 As shown, after adjusting the distance between the placement platform 10 and the support plate 17, the plate is placed on top of the placement platform 10 and the support plate 17. Then, the controller controls the operation of two sets of electric push rods 15 inside the placement platform 10. Since the output end of the electric push rod 15 is fixedly connected to the right end of the left guide plate 14 in the placement platform 10, and a rotating rod 12 is rotatably connected to the middle position inside the placement platform 10, and both ends of the rotating rod 12 are rotatably connected to hinge rods 13, and the rotating rod 12 and the hinge rod 13 are arranged in a "Z" shape, and the hinge rod 13 is also rotatably connected to the side wall of the guide plate 14, and is also fixedly clamped at the top left and right ends of the placement platform 10. The lower end of the plate 11 extends through into the interior of the placement platform 10, and the guide plate 14 at one end of the fixed clamping plate 11 inside the placement platform 10 is fixedly connected together. When the electric push rod 15 runs, it can drive the left guide plate 14 in the placement platform 10 to slide inside the placement platform 10. Through the cooperation between the rotating rod 12 and the hinge rod 13, it can drive the two sets of guide plates 14 to slide synchronously, and at the same time drive the two sets of fixed clamping plates 11 to slide in opposite directions, so that the fixed clamping plates 11 at the top left and right ends of the placement platform 10 approach each other and fix the plate on the placement platform 10 and the support plate 17. The fixing of the plate by the fixed clamping plate 11 can prevent the plate from slipping or moving during the processing of the plate, and avoid the bending angle and position deviation caused by the movement of the plate.

[0032] After the plate is fixed above the placement platform 10 and the support plate 17, conveying grooves 3 are fixedly installed on both the left and right ends of the top of the base 1. The controller then controls two sets of motors 7 to rotate synchronously forward or backward. Synchronous pulleys 5 are rotatably connected to both the front and rear ends inside the conveying grooves 3. The front and rear synchronous pulleys 5 in the conveying grooves 3 are connected together by a belt 6. A connecting block 4 is slidably connected to the side wall of the conveying groove 3 and is fixedly connected to the belt body of the lower belt 6 in the conveying groove 3. A sliding plate 8 is slidably connected to the front end of the top of the base 1 and is fixedly connected to the connecting block 4. Connecting rods 9 are fixedly installed on both the left and right ends of the rear end of the sliding plate 8, and the rear end of the connecting rod 9 is fixedly connected to the front end of the placement platform 10. When the controller controls the two sets of motors 7 to run, the output end of the motor 7 is fixedly connected to the shaft of the front synchronous pulley 5 in the conveying groove 3. When the motor 7 is running, it drives the belt 6 to rotate via the synchronous pulley 5. The synchronous pulley 5 and the belt 6 work together to drive the connecting block 4 to slide on the side wall of the conveying trough 3. Then, the connecting block 4 is fixedly connected to the sliding plate 8, and drives the sliding plate 8 to slide on the top of the base 1. At the same time, the connecting rod 9 drives the placement table 10 to slide on the top of the base 1. The placement table 10 also drives the support plate 17 to move. The sliding of the placement table 10 can transport the support plate 17 to the bending point of the bending machine body 2. The gap between the support plate 17 and the placement table 10 is placed at the bending point of the bending machine body 2. At the same time, the plate on the placement table 10 and the support plate 17 is placed below the bending point of the bending machine body 2. The operation of the motor 7 can drive the movement of the placement table 10 and the support plate 17, so that the plate can be automatically conveyed and the plate can be kept stable during the processing. This reduces the influence of human factors on the bending accuracy and ensures a consistent bending effect.
