Description

Technical Field

[0001] The utility model relates to a double-feeding device and a clutch plate punching machine thereof. Background Art

[0002] In the clutch plate manufacturing industry, automatic stamping machines are a key production equipment. However, existing clutch plate automatic stamping machines face some significant technical challenges in practical application, mainly in terms of feeding efficiency and degree of automation.

[0003] Traditional clutch plate stamping machines typically place a round metal block underneath the press, which then presses down to remove the center of the block, forming a metal ring. There are two main feeding methods: manual and automatic.

[0004] Manually placing metal round blocks is a relatively simple and direct method, requiring operators to continuously place the metal round blocks into the stamping area. However, this method has obvious drawbacks: first, manual operation is inefficient and cannot meet the needs of modern large-scale production; second, long-term repetitive work can easily lead to operator fatigue, increasing the risk of operational errors; finally, the instability of manual operation can affect the consistency of product quality.

[0005] To improve efficiency, some manufacturers have adopted automatic feeding systems. However, existing automatic feeding devices are often complex in design, requiring sophisticated control systems and complex mechanical structures. While this complex automation process reduces manual intervention, it also introduces new challenges: system commissioning and maintenance are complex, equipment failure rates increase, and actual production efficiency remains suboptimal due to the waiting time between each feeding and stamping.

[0006] In addition, whether manual or automatic feeding, the existing system has a common problem: after each stamping is completed, a certain amount of time is required to reload a new metal block and place it under the stamping machine. This process causes interruptions in the production line and limits the improvement of overall production efficiency.

[0007] To address these issues, this application proposes an innovative dual-feeding device and its associated automatic clutch plate stamping machine. The core concept of this design is to achieve a continuous and efficient feeding process through the dual-feeding mechanism. After a single stamping cycle is completed, a new metal round can be quickly fed into the stamping area, significantly reducing waiting time. This approach not only significantly improves production efficiency but also reduces reliance on complex automation systems. Utility Model Content

[0008] The purpose of the utility model is to provide a double-feeding device and a clutch plate punching machine thereof, which can improve production efficiency and reduce program design costs.

[0009] The above technical objectives of the present invention are achieved through the following technical solutions:

[0010] A double feeding device includes: two conveying racks, which are slidably arranged on a workbench, and each conveying rack is provided with a conveying trough and a conveying belt passing through the conveying rack on one side; two connecting plates, respectively connecting the two conveying racks; a frame, whose two ends are respectively fixedly connected to the two connecting plates, and the middle of the frame is hollow; a cam, which is arranged in the frame; a stepping motor, which is fixedly connected to one end of the cam and is used to drive the cam to rotate, thereby driving the frame and the conveying rack to slide back and forth, thereby realizing automatic conveying of metal round blocks.

[0011] The utility model is further configured such that the conveying trough is semicircular or in an arc shape exceeding a semicircle.

[0012] The utility model is further configured such that the sliding distance of the conveying frame driven by the cam is equal to the distance between the center of the installation groove and the center of the conveying groove.

[0013] A clutch plate stamping machine is characterized by comprising: a frame; a workbench arranged in the middle of the frame, with a mounting slot provided in the middle of the workbench; a stamping mechanism arranged directly above the workbench so as to be movable up and down; and the above-mentioned double feeding device arranged on both sides of the workbench.

[0014] The utility model is further configured to include an automatic material receiving device, which includes: an arc-shaped magnet, which is slidably arranged in the installation groove; a driven rod, which is fixedly connected to one side of the arc-shaped magnet; a gear, which is engaged with one side of the driven rod; an active rod, which is engaged with one side of the gear and is staggered with the driven rod; a slider, which is connected to one end of the active rod; and a positioning rod, which is passed through the middle of the slider and is fixedly connected to the frame.

[0015] The utility model is further configured as follows: the slider is fixedly connected to the bracket, and the slider is driven by a hydraulic cylinder to slide longitudinally, driving the stamping mechanism to move up and down, and at the same time driving the active rod, gear, driven rod and arc magnet to move, thereby realizing automatic material collection of the formed metal ring.

[0016] The utility model is further configured such that when the slider moves downward, it drives the active rod to move downward, causing the gear to rotate clockwise, thereby driving the driven rod and the arc-shaped magnet to move along the installation slot toward the middle of the workbench.

[0017] The utility model is further configured such that when the slider moves upward, the arc-shaped magnet is reset, driving the adsorbed metal ring to move outward and be suspended in the air, so that the metal ring falls under its own gravity.

[0018] In summary, the present invention has the following beneficial effects:

[0019] 1. High degree of automation:

[0020] The coordinated operation of the dual feeding device, the punching mechanism and the automatic receiving device realizes a fully automated process from feeding, punching to receiving. This greatly reduces manual intervention, improves production efficiency and reduces labor costs.

[0021] 2. Improved production efficiency:

[0022] The reciprocating motion of the dual feeder ensures a continuous and stable supply of metal rounds, the rapid up and down movement of the punching mechanism ensures an efficient stamping process, and the reciprocating motion of the automatic receiving device ensures the timely collection of the stamped finished products. This highly coordinated working mode significantly improves production efficiency.

[0023] 3. Product quality assurance:

[0024] The automated process reduces human error and ensures product consistency and quality. In particular, the automatic material collection device uses a curved magnet design that gently collects the stamped products, avoiding product deformation or damage that may occur with traditional material collection methods.

[0025] 4. Improved security:

[0026] Fully automated operation significantly reduces the operator's exposure to the equipment, reducing workplace safety risks. Especially during high-speed stamping, the use of an automatic material collection device eliminates potential safety hazards associated with manual material collection.

[0027] 5. Strong adaptability:

[0028] The semicircular or more than semicircular arc design of the conveying trough and the adjustable stamping mechanism enable the equipment to adapt to the production needs of clutch plates of different sizes and shapes, enhancing the versatility and adaptability of the equipment.

[0029] 6. Easy maintenance:

[0030] Compared to complex pneumatic or hydraulic material collection systems, the mechanical transmission method adopted in this design is simple in structure and easy to maintain and debug. This not only reduces equipment maintenance costs, but also reduces downtime caused by equipment failure.

[0031] 7. Save space:

[0032] The automatic material collection device is integrated into the workbench of the punching machine, eliminating the need for additional material collection equipment, resetting the overall space layout and improving space utilization.

[0033] 8. Environmentally friendly:

[0034] Compared with the pneumatic collecting system, this design does not require compressed air, reduces energy consumption and noise pollution, and is more environmentally friendly.

[0035] 9. Flexible production:

[0036] By adjusting the motion parameters of the double feeding device and the punching force of the punching mechanism, the equipment can adapt to metal materials of different materials and thicknesses to achieve flexible production. BRIEF DESCRIPTION OF THE DRAWINGS

Thus, a feature specified as "first" or "second" may explicitly or implicitly include one or more of the features.

[0044] In the description of this utility model, "plurality" means two or more, unless otherwise clearly defined. In this utility model, unless otherwise clearly defined and defined, the terms "installed," "connected," "connected," "fixed," etc. should be understood in a broad sense. For example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection, an indirect connection through an intermediate medium, or it can be internal communication between two components. For those skilled in the art, the specific meanings of the above terms in this utility model can be understood according to the specific circumstances.

[0045] The present invention will be described in further detail below with reference to the accompanying drawings.

[0046] like Figure 1 As shown, a clutch plate stamping machine includes a frame 1. A workbench 2 is provided in the middle of the frame 1, and a stamping mechanism 3 is located directly above the workbench 2, which can move up and down. This stamping mechanism 3 includes a bracket 4. A hydraulic cylinder 22 drives the bracket 4 up and down, thereby moving the entire stamping mechanism 3 up and down. During the downward movement, the metal round block 5 is pressed, thereby obtaining a metal ring, that is, an integrally formed clutch plate. A mounting groove 6 is provided in the middle of the workbench 2. The metal round block 5 to be stamped can be placed in the mounting groove 6. Example

[0047] like Figure 1 、 Figure 2 As shown, a double feeding device 7 is provided on both sides of the workbench 2, and the double feeding device 7 includes two conveying racks 8 slidably provided on the workbench 2. A conveying trough 9 is provided on one side of the conveying rack 8 and passes through the conveying rack 8. The conveying trough 9 is semicircular or an arc shape exceeding a semicircle.

[0048] A conveyor belt 10 is provided on one side of the conveyor frame 8. The conveyor belt 10 can be driven by a motor to continuously work, and the metal round block 5 to be punched is placed on the conveyor belt 10 for transportation.

[0049] Furthermore, the two conveying racks 8 are respectively connected to two connecting plates 11. The two opposite ends of the two connecting plates 11 are fixedly connected to a frame 12. The middle part of the frame 12 is hollow, and a cam 13 is provided inside the frame 12. One end of the cam 13 is fixedly connected to a stepper motor 14. When the stepper motor 14 is working, it can drive the cam 13 in the frame 12 to rotate. When the distal end of the cam 13 contacts the left and right sides of the frame 12, the frame 12 can move under the push of the cam 13. In the process of the stepper motor 14 driving the cam 13 to rotate one circle, the cam 13 drives the conveying racks 8 on both sides to slide back and forth once. The distance of this sliding is exactly the distance between the center of the mounting groove 6 and the center of the conveying groove 9.

[0050] Under the above setting, the staff first places a number of metal round blocks 5 on the conveyor belts 10 on both sides. The initial state is as follows Figure 1 As shown, at this time, the distal end of the cam 13 is facing upwards and the punching mechanism 3 is not pressed down. The conveyor belt 10 is started, so that a metal round block 5 on the conveyor belt 10 enters the conveying groove 9 on one side of the conveyor frame 8. The other metal round blocks 5 are blocked by the metal round blocks 5 that entered earlier and cannot enter the conveying groove 9. The stepper motor 14 is started, driving the cam 13 to rotate 90 degrees clockwise, thereby pushing the frame 12 Figure 1 The frame 12 moves to the right as shown. The movement of the frame 12 drives both conveyor racks 8 to the right, causing the metal block 5 in the left conveyor rack 8 to move to the position of the mounting slot 6, allowing the metal block 5 to enter the mounting slot 6. The stepper motor 14 continues to rotate 90 degrees. At this time, the external spring return mechanism resets the frame 12 and conveyor rack 8. This reset mechanism is conventional and will not be described in detail here.

[0051] After the frame 12 is reset, the punching mechanism 3 presses down, pressing the metal round block 5 into a metal ring. Afterwards, the formed metal ring is removed, and the cam 13 rotates 90 degrees further, causing the frame 12 to move left, so that the right conveyor frame 8 can input the corresponding metal round block 5 into the installation groove 6 for further pressing.

[0052] Under the above setting, after the conveyor rack 8 on one side inputs the metal round block 5 each time, the conveyor rack 8 on the other side has already loaded the metal round block 5. The material collecting mechanism of the metal ring that automatically recycles can realize the overall automatic operation without interruption, improve production efficiency and reduce the complexity of program design. Example

[0053] like Figure 3 、 Figure 4 As shown, an automatic material receiving device 15 is installed on one side of the middle portion of the workbench 2. The automatic material receiving device 15 includes an arc-shaped magnet 16 that slides within the mounting slot 6. A driven rod 17 is fixedly connected to one side of the arc-shaped magnet 16. A gear 18 is meshed with one side of the driven rod 17. A driving rod 19 is meshed with one side of the gear 18. The driving rod 19 and the driven rod 17 are interlaced and do not interfere with each other.

[0054] One end of the active rod 19 is connected to a slider 20. A positioning rod 21 is inserted through the middle of the slider 20. The positioning rod 21 is fixedly connected to the frame 1, wherein the slider 20 is fixedly connected to the bracket 4. The longitudinal sliding movement of the slider 20 driven by the hydraulic cylinder 22 can drive the stamping mechanism 3 to move up and down to complete the stamping operation.

[0055] As mentioned above, when the slider 20 moves downward, it can drive the active rod 19 downward. The downward movement of the active rod 19 drives the gear 18 to rotate clockwise, which in turn drives the driven rod 17 and magnet 16 to move along the mounting groove 6 toward the center of the workbench 2. When the punching mechanism 3 moves downward until the center of the metal block 5 is pressed out of the through hole to form a metal ring, the driven rod 17 drives the magnet 16 to contact the outside of the metal ring, attracting the metal ring.

[0056] When the slider 20 moves upward, the magnet 16 is reset. At this time, the magnet 16 drives the metal ring to move outward, takes the metal ring out of the workbench 2, and makes the metal ring suspended in the air. The metal ring falls under its own gravity, completing the process of automatically recovering the metal ring.

[0057] This specific embodiment is merely an explanation of the present invention and is not a limitation of the present invention. After reading this specification, those skilled in the art may make non-creative modifications to the present embodiment as needed. However, as long as they are within the scope of the claims of the present invention, they are protected by patent law.
