Description
Technical Field
[0001] The utility model relates to the technical field of multi-station progressive dies, in particular to a multi-station progressive die with a floating plate material guiding device. Background Art
[0002] A floating plate material guiding device is a device used to guide the flow of materials, usually applied in multi-station progressive dies. Its main function is to ensure the smooth flow of materials in the die, improve production efficiency and product quality. The floating plate material guiding device usually consists of a floating plate, guiding columns, springs, etc. The floating plate can float up and down on the guiding columns and keep in contact with the materials through the action of springs. When the die is working, the floating plate can move up and down with the flow of materials to guide the materials into the next station, thus realizing continuous production.
[0003] Existing multi-station progressive dies complete the processing of multiple processes, such as punching, blanking, bending, stretching, etc. in one die through continuous stamping actions. Feeding ports and discharging ports are respectively provided on the punch and the die. The materials sequentially pass through each station in the die to complete different processing processes. The multi-station progressive die can complete the processing of multiple processes in a short time, greatly improving production efficiency.
[0004] However, most multi-station progressive dies directly perform stamping, which may cause damage to workpieces or dies. Especially when processing brittle materials or workpieces with complex shapes, the impact force can cause cracks or deformations.

[0033] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the protection scope of the present invention.
[0034] Refer to Figure 1 - Figure 3 , an embodiment provided by the present invention: a multi-station progressive die with a floating plate feeding device, including a base 1, a first sliding rod 3 fixedly connected inside the base 1, a cylinder 6 fixedly connected to the top of the base 1, a pressing plate 5 fixedly connected to the output end of the cylinder 6, the pressing plate 5 is slidably connected to the outer wall of the first sliding rod 3, a first spring 4 is sleeved on the outer wall of the first sliding rod 3, one end of the first spring 4 is fixedly connected to the bottom of the pressing plate 5, the other end of the first spring 4 is fixedly connected to the inner wall of the base 1, an upper mold 7 is fixedly connected to the bottom of the pressing plate 5, a lifting plate 8 is slidably connected inside the base 1, a plurality of lower molds 9 are fixedly connected to the top of the lifting plate 8, a plurality of transmission rods 16 are rotatably connected to the bottom of the lower mold 9, a slide block 12 is rotatably connected to one side of the transmission rod 16, a second sliding rod 11 is fixedly connected inside the base 1, the slide block 12 is slidably connected inside the second sliding rod 11, a second rotating block 15 is rotatably connected to the bottom of the lifting plate 8, a damper 14 is fixedly connected to one side of the outer wall of the second rotating block 15, a first rotating block 13 is rotatably connected to one side of the outer wall of the slide block 12, and one side of the outer wall of the first rotating block 13 is fixedly connected to the output end of the damper 14. A second spring 10 is sleeved on the outer wall of the second sliding rod 11, and both ends of the second spring 10 are fixedly connected to one side of the outer wall of the slide block 12;
[0035] Specifically, when performing the stamping operation, the pressing plate 5 can be driven by the air cylinder 6. In this way, the pressing plate 5 can slide smoothly on the surface of the first slide bar 3, and then drive the upper die 7 to press downward. When the upper die 7 presses on the lifting plate 8, the lifting plate 8 will slide downward, and at the same time, transmit the force to the slider 12 through the transmission rod 16. After that, the two sliders 12 will slide relative to each other on the second slide bar 11, so that the forces cancel each other out. During the process of the transmission rod 16 transmitting the force, the damper 14 can not only play a buffering role but also provide support to ensure the stable operation of the entire mechanism. In addition, when the two sliders 12 slide relative to each other, the second spring 10 will play a buffering role to further reduce the impact force and protect the mechanism from damage. Such a design can make the stamping process more stable and efficient, and at the same time extend the service life of the equipment.
[0036] Refer to Figure 4 - Figure 6 On both sides inside the base 1, a motor 18 is fixedly connected. The output end of the motor 18 is fixedly connected with a second gear 20. On both sides inside the base 1, a pair of symmetrically arranged first gears 19 are rotatably connected. The outer wall of the first gear 19 meshes with the outer wall of the second gear 20. The top of the second gear 20 is rotatably connected inside the base 1. On one side of each of the pair of symmetrically arranged first gears 19, a connecting rod 17 is rotatably connected. The outer wall of the connecting rod 17 is fixedly connected with a plurality of bottom columns 21. Inside the bottom column 21, a sliding column 22 is slidably connected. On one side of the outer wall of the sliding column 22, a protection assembly is provided. The protection assembly is used to prevent the workpiece from being scratched during transportation. The protection assembly includes a gasket 23. One side of the outer wall of the gasket 23 is fixedly connected to one side of the outer wall of the sliding column 22. Inside the bottom column 21, a gasket 23 is fixedly connected. One end of the gasket 23 is fixedly connected to the inner wall of the sliding column 22. A third spring 24 is sleeved on the outer wall of the gasket 23. One end of the third spring 24 is fixedly connected to the inner wall of the bottom column 21, and the other end of the third spring 24 is fixedly connected to the inner wall of the sliding column 22;
[0037] Specifically, during the process of guiding the workpiece, the two second gears 20 can be driven to rotate synchronously by the motor 18. Driven by the two second gears 20 at the same time, the connecting rod 17 will perform a reciprocating motion. Thus, the bottom column 21 on the connecting rod 17 can drive the sliding column 22 to clamp towards the central position. With the force of the third spring 24, it can adapt to the change in the movement distance. In this way, the workpiece can be smoothly guided from the previous process to the next process, realizing an efficient production process.
[0038] Refer to Figure 1 And Figure 2 On one side inside the base 1, a discharge pipe 2 is fixedly connected;
[0039] Specifically, a discharge pipe 2 is provided on one side of the base 1, so that when performing the guiding process, the processed workpiece can be automatically taken out, facilitating the independent collection of the workpiece.
[0040] Working principle: When stamping, the pressing plate 5 can be driven by the air cylinder 6, so that the pressing plate 5 can slide on the surface of the first sliding rod 3, thereby driving the upper die 7 to press down. When the upper die 7 presses on the lifting plate 8, the lifting plate 8 can slide downward, and then the force is transmitted to the slider 12 through the transmission rod 16. Then, the two sliders 12 can slide on the second sliding rod 11, so that the two sliders 12 slide relatively to cancel the force. When the transmission rod 16 conducts the force, the damper 14 can be used for buffering and supporting. At the same time, when the two sliders 12 slide relatively, the second spring 10 will be used for buffering. When feeding the workpiece, the two second gears 20 can be driven by the motor 18 to rotate synchronously. Then, under the synchronous drive of the two second gears 20, the connecting rod 17 can reciprocate. Thus, the bottom column 21 on the connecting rod 17 drives the sliding column 22 to clamp towards the center, and the force of the third spring 24 is applied to adapt to the change in the movement distance. Then, the workpiece can be introduced from the previous process to the next process.
[0041] Finally, it should be noted that the above are only the preferred embodiments of the present invention and are not used to limit the present invention. Although the present invention has been described in detail with reference to the foregoing embodiments, for those skilled in the art, they can still modify the technical solutions described in the foregoing embodiments, or perform equivalent replacements for some of the technical features. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
