Description

Technical Field

[0001] This utility model relates to the technical field of feeding devices, specifically to a feeding device for a molding machine. Background Technology

[0002] The molding machine applies pressure to the mold, and through the mold, it applies external force to the sheet metal, profiles, etc., causing them to undergo plastic deformation or separation, thereby obtaining workpieces of the required shape and size. Ensuring the feeding speed is crucial to ensuring the processing efficiency of the molding machine.

[0003] Chinese Utility Model Patent No. CN216176051U discloses a high-efficiency metal stamping and forming machine with automatic feeding function. The machine includes a worktable, a work frame fixedly connected to the surface of the worktable, a first hydraulic cylinder mounted on the surface of the work frame, a moving plate fixedly connected to the output end of the first hydraulic cylinder, a punch die fixedly connected to the bottom of the moving plate, and a fixed die mounted on the surface of the worktable. This utility model, through the worktable, transmission frame, feeding frame, moving plate, second hydraulic cylinder, transmission plate, fixed frame, friction roller, rotating rod, first motor, second motor, transmission belt, transmission roller, driven rod, and driving rod, enables the device to achieve automatic feeding function. This solves the problem that existing metal stamping and forming machines on the market lack automatic feeding function, requiring manual feeding by workers, which is time-consuming and labor-intensive, affecting work efficiency and hindering rapid product processing and production.

[0004] In the aforementioned high-efficiency metal stamping machine with automatic feeding function, the user opens the cabinet door and places multiple sets of sheet metal on the surface of the transmission plate. The second hydraulic cylinder is activated, causing the transmission plate to move and lift the sheet metal. After the sheet metal on the transmission plate is loaded, the plate needs to be lowered before new sheet metal can be placed on it, and then the feeding process can begin again. This results in poor feeding continuity, leading to a decrease in feeding speed and affecting the equipment's processing efficiency. Therefore, the existing technology suffers from the technical problem of poor feeding continuity. Utility Model Content

[0005] In order to solve the above-mentioned technical problems, the purpose of this utility model is to provide a feeding device for a molding machine, which includes a slide rail, a sliding frame, a first lifting plate, a second lifting plate, a support frame and a lifting frame. The feeding device for the molding machine has the advantage of good feeding continuity.

[0006] To achieve the above-mentioned objectives, the technical solution adopted by this utility model is as follows:

[0007] A feeding device for a molding machine includes a slide rail, a sliding frame, a first lifting plate, a second lifting plate, a support frame, and a lifting frame.

The lower end of the auxiliary pressure wheel is at the same height as the lower end of the drive wheel.

[0012] This setup ensures the reliability of the sheet metal when driven by the drive wheel.

[0013] Preferably, a feeding port is provided on one side of the feeding area, the drive wheel is located at the center of the feeding area near the feeding port, and the auxiliary pressure roller is located at the center of the feeding area away from the feeding port.

[0029] To make the objectives, technical solutions and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the embodiments. However, the scope of protection of this utility model is not limited to the specific embodiments described below.

[0030] refer to Figure 1 and Figure 2 A feeding device for a molding machine includes a slide rail 11, a sliding frame 12, a first lifting plate 13, a second lifting plate 14, a support frame 21, and a lifting frame 22. The sliding frame 12 is slidably connected to the slide rail 11. A first guide rod 15 and a second guide rod 16 are fixedly connected to the sliding frame 12. The first lifting plate 13 and the second lifting plate 14 are slidably connected to the first guide rod 15 and the second guide rod 16, respectively. A connecting rod 17 is provided between the first guide rod 15 and the second guide rod 16. The connecting rod 17 is fixedly connected to the first guide rod 15 and the second guide rod 16, and supports the first guide rod 15 and the second guide rod 16 through the connecting rod 17, thereby improving the structural stability of the first guide rod 15 and the second guide rod 16.

[0031] The slide rail 11 has a first feeding area 41 and a second feeding area 42 at both ends, which respectively accommodate the first lifting plate 13 and the second lifting plate 14. A loading area 43 is located in the middle of the slide rail 11, and the lifting frame 22 is positioned above the loading area 43. A loading port 44 is located on one side of the loading area 43. When the first lifting plate 13 is located in the loading area 43, the second lifting plate 14 is located in the second feeding area 42; when the second lifting plate 14 is located in the loading area 43, the first lifting plate 13 is located in the first feeding area 41. The sliding frame 12 is equipped with a first hydraulic cylinder and a second hydraulic cylinder. The push rod of the first hydraulic cylinder is connected to the first lifting plate 13. When the first hydraulic cylinder extends and retracts, it drives the first lifting plate 13 to rise and fall. The push rod of the second hydraulic cylinder is connected to the second lifting plate 14. When the second hydraulic cylinder extends and retracts, it drives the second lifting plate 14 to rise and fall.

[0032] The lifting frame 22 is slidably connected to the support frame 21. A cylinder 23 is provided between the lifting frame 22 and the support frame 21. The cylinder 23 is fixedly mounted on the support frame 21. The cylinder 23 has a piston rod 24, which passes through the lifting frame 22. A locking block 25 is fixedly connected to the piston rod 24 and engages with the lifting frame 22. The cylinder 23 is vertically arranged. Gas is introduced into the cylinder 23, which pushes the piston rod 24 to move on the cylinder 23. The piston rod 24 pushes the lifting frame 22 to slide on the support frame 21 through the locking block 25. When the drive wheel 32 needs to contact the plate, the cylinder 23 drives the piston rod 24 to move downward, causing the lifting frame 22 to fall freely without the support of the locking block 25, allowing the drive wheel 32 to contact the plate. When the sliding frame 12 needs to move on the slide rail 11, the cylinder 23 drives the piston rod 24 to move upward, preventing the drive wheel 32 from jamming the first lifting plate 13 and the second lifting plate 14.

[0033] The lifting frame 22 is equipped with a rotating wheel device, which includes a drive shaft 31 and an auxiliary shaft 34. The drive shaft 31 is rotatably connected to the lifting frame 22, and a drive wheel 32 is fixedly connected to the drive shaft 31. The lifting frame 22 is equipped with a rotary drive component 33 connected to the drive shaft 31. The rotary drive component 33 drives the drive wheel 32 to rotate via the drive shaft 31, thus achieving the function of driving the drive wheel 32 to rotate. The auxiliary shaft 34 is rotatably connected to the lifting frame 22 and is parallel to the drive shaft 31. An auxiliary pressure roller 35 is fixedly connected to the auxiliary shaft 34, and the lower end of the auxiliary pressure roller 35 is at the same height as the lower end of the drive wheel 32. When the drive wheel 32 abuts against the plate, the auxiliary pressure roller 35 can also abut against the upper surface of the plate. By having the drive wheel 32 and the auxiliary pressure roller 35 simultaneously provide support at different positions on the upper surface of the plate, the reliability of the plate when driven by the drive wheel 32 is ensured. The drive wheel 32 is located at the center of the feeding area 43, near the feeding port 44, while the auxiliary pressure wheel 35 is located at the center of the feeding area 43, away from the feeding port 44. The drive wheel 32 is positioned on the side of the auxiliary pressure wheel 35 closest to the feeding port 44 to ensure that the sheet metal can be pushed to the feeding port 44 by the drive wheel 32, preventing the drive wheel 32 from failing to reach the feeding port 44 when it is detached from the material. The rotary drive component 33 is a motor, and the motor's output shaft is fixedly connected to the drive shaft 31, enabling the rotary drive component 33 to drive the drive shaft 31 to rotate.

[0034] A screw 26 is mounted on the support frame 21. A limit switch 27 located in the loading area 43 is fixedly connected to the lower end of the screw 26, allowing for height positioning of the sheet material. The screw 26 passes through the support frame 21 and is threaded onto two nuts 28, which are engaged with the support frame 21 in opposite directions. Loosening the nuts 28 allows the screw 26 to move vertically on the support frame 21, adjusting the height of the limit switch 27 to accommodate sheets of different thicknesses and improve adaptability. After adjusting the height of the limit switch 27, tightening the two nuts 28 secures the screw 26 to the support frame 21.

[0035] Specific work process:

[0036] The molding machine is set at the feeding port 44. The sliding frame 12 is pushed to move on the slide rail 11. The sliding frame 12 drives the first lifting plate 13 to move into the first feeding area 41. Multiple plates are stacked on the first lifting plate 13 in the first feeding area 41. Then, the sliding frame 12 is pushed to move on the slide rail 11, driving the first lifting plate 13 to move into the feeding area 43. The first lifting plate 13 is driven to move upward, driving the plates on the first lifting plate 13 to move upward. When the plates contact the limit switch 27, the movement stops. At this time, the drive wheel 32 contacts the plates. The motor drives the drive wheel 32 to rotate, causing the drive wheel 32 to push the board through the loading port 44 and out of the loading area 43 through friction. After a board is pushed out of the loading area 43, the limit switch 27 is released from contact with the board, and then the first lifting plate 13 continues to move upward until a board comes into contact with the limit switch 27 again and stops moving. The drive wheel 32 pushes the board out of the loading area 43 again, and the cycle continues until all the boards on the first lifting plate 13 are pushed out, thus realizing the loading function.

[0037] When the first lifting plate 13 is located in the feeding area 43, it can simultaneously place new boards onto the second lifting plate 14 in the second feeding area 42. After all the boards on the first lifting plate 13 are pushed out of the feeding area 43 by the drive wheel 32, the first lifting plate 13 is driven to move downward to the lowest position. Then, the sliding frame 12 can be immediately pushed to move on the slide rail 11, driving the second lifting plate 14 to move into the feeding area 43, and multiple new boards are stacked on the first lifting plate 13 in the first feeding area 41. The second lifting plate 14 is driven to move upward, driving the boards on the second lifting plate 14 to move upward. When the boards contact the limit switch 27, the movement stops, at which point the drive wheel 32 contacts the boards. The motor drives the drive wheel 32 to rotate, causing the drive wheel 32 to push the board through the loading port 44 and out of the loading area 43 through friction. After a board is pushed out of the loading area 43, the limit switch 27 is released from contact with the board, and then the second lifting plate 14 continues to move upward until a board comes into contact with the limit switch 27 again and stops moving. The drive wheel 32 pushes the board out of the loading area 43 again, and the cycle continues until all the boards on the second lifting plate 14 are pushed out.

[0038] When the second lifting plate 14 is located in the feeding area 43, it can simultaneously place new plates on the first lifting plate 13 in the first feeding area 41. After all the plates on the second lifting plate 14 are pushed out of the feeding area 43 by the drive wheel 32, the second lifting plate 14 is driven to move downward to the lowest position. Then, the sliding frame 12 can be pushed to move on the slide rail 11, which will move the first lifting plate 13 into the feeding area 43 and place new plates on the second lifting plate 14 in the second feeding area 42.

[0039] This embodiment has the following advantages:

[0040] While the first lifting plate 13 is feeding materials into the feeding area 43, it can simultaneously place new materials onto the second lifting plate 14. Once the materials on the first lifting plate 13 are exhausted, the system can immediately switch to feeding from the second lifting plate 14. Similarly, while the second lifting plate 14 is feeding materials into the feeding area 43, it can simultaneously place new materials onto the first lifting plate 13. Once the materials on the second lifting plate 14 are exhausted, the system can immediately switch back to feeding from the first lifting plate 13. This cycle repeats continuously, enabling long-term, rapid feeding with good continuity, which is beneficial for feeding speed and ensures the processing efficiency of the molding machine, achieving the advantage of good feeding continuity.
