Description

Technical Field

[0001] This utility model relates to the field of punch press technology, specifically a guide device for a high-speed punch press. Background Technology

[0002] A punch press is essentially a stamping press. In national production, stamping technology has become increasingly widely used due to its advantages over traditional machining: saving materials and energy, high efficiency, lower operator skill requirements, and the ability to produce products that cannot be achieved through machining using various molds. Stamping production is primarily for sheet metal. Using molds, it can produce blanking, punching, forming, deep drawing, trimming, fine blanking, shaping, riveting, and extruded parts, among many others, finding wide application in various fields. For example, many components of switches and sockets, cups, cabinets, plates, computer cases, and even missiles and aircraft can be produced using punch presses and molds.

[0003] A search revealed a high-speed punch press slide guide device with Chinese patent application number 202021462299.X, comprising a foot, a worktable, a middle seat, a linear motor assembly, and a slide. The foot is horizontally positioned, the worktable is mounted on the foot, and there are two middle seats, vertically mounted on the foot and located on opposite sides of the worktable. The linear motor assemblies are mounted on the inner sides of the two middle seats. The eight sides of the slide are fixedly connected to the linear motor assemblies and located above the worktable. The linear motor can directly drive the slide to move up and down rapidly to achieve the punching action, and can also directly drive the slide to move up and down slowly to achieve the mold adjustment action. The linear motor can also directly drive the slide to achieve stepless speed regulation and can generate a punching curve with rationalized process, whereas traditional crank-connecting rod punch presses only have one fixed punching curve once the design is completed.

[0004] In the above technical solution, the slide block used for stamping is driven downward by linear motors at the four corners and cooperates with the worktable to complete the stamping. However, the use of multiple motors to drive the slide block results in high equipment cost, inconvenient maintenance and repair, and difficulty in operation due to the synchronous drive of multiple motors. In addition, the stamped workpiece is inconvenient to remove from the stamping cavity on the worktable, making it inconvenient to use. Utility Model Content

[0022] 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.

[0023] Example

[0024] like Figure 1 , Figure 2 , Figure 3 and Figure 4As shown in one embodiment of this utility model, a guide device for a high-speed punch press includes a base 1. Foot seats 2 are fixedly connected to both sides of the lower part of the base 1. A worktable 3 is mounted on the upper part of the base 1, and center seats 5 are provided on both sides. The base 1, foot seats 2, and center seats 5 are stably connected together to form a frame for mounting a punching slide 6 and the worktable 3, allowing for stable cooperation between the two to complete the punching process. The center seats 5 are fixedly connected to the base 1 via a connecting rod 9, ensuring a stable connection between the two. A driving component 7 slidably connected to the connecting rod 9 has a punching slide 6 fixedly connected to its lower part. A worm gear 704 on the driving component 7 is threadedly connected to a screw 8 mounted on the center seat 5 via a threaded sleeve 709. The worm gear 704 is connected to the worm 705 at the end of the transmission shaft 706, and the transmission shaft 706 is connected to the servo motor 707, facilitating the operation of the servo motor 707. Through the cooperation of the transmission shaft 706 and the worm 7005, the worm gear 704 is driven to rotate on the screw 8, driving the entire drive component 7 to slide on the connecting rod 9 on the middle seat 5 with the stamping slide 6, ensuring that the stamping slide 6 can cooperate with the workpiece 3 to complete the stamping process. The worktable 3 is equipped with a material ejection component 4, which facilitates pushing the stamped workpiece from the stamping cavity after stamping, smoothly completing the material ejection operation, facilitating quick retrieval of the stamped workpiece, making it convenient to use, and improving the efficiency and convenience of stamping processing.

[0025] like Figure 1 and Figure 2 As shown, in some embodiments, the unloading assembly 4 includes a movable frame 401, which is slidably disposed in the movable area provided under the workbench 3 and slidably connected to the mounting rod 403. This facilitates the stable installation of the movable frame 401 in the movable area under the workbench 3 using the mounting rod 403, allowing the movable frame 401 to move smoothly in the movable area when driven by external force, thereby performing the subsequent unloading operation. The lower end of the mounting rod 403 is fixedly inserted into the base 1, and the upper end abuts against the workbench 3. A support spring 404 is fitted on the mounting rod 403 between the frame 401 and the base 1 to provide stable and effective support for the movable frame 401, so that it is initially attached to the worktable 3. A top material block 402 is fixedly connected to the upper part of the movable frame 401. The top material block 402 cooperates with the slot provided on the worktable 3. The top material block 402 is used to push out the stamped workpiece in the stamping cavity formed by the slot during use, so that the stamped part can be smoothly ejected, improving the stamping efficiency and making it easy to use.

[0026] like Figure 1 , Figure 3 and Figure 4As shown, in some embodiments, the drive component 7 includes a mounting frame 701, which is slidably connected to the connecting rod 9 through a sliding hole 702, so that the entire drive component 7 can slide smoothly up and down on the connecting rod 9 on the middle seat 5, ensuring stable operation. A push rod 703 is mounted on the lower part of the mounting frame 701, and a sleeve is provided on the mounting frame 701 at the position corresponding to the worm gear 704. The sleeve is rotatably connected to the threaded sleeve 709 on the worm gear 704 through a bearing, so that the worm gear 704 can be smoothly rotated on the mounting frame 701 when driven by the worm 705, ensuring that the worm gear 704 can rotate on the screw 8 during the driving process, thereby achieving stable and effective thread drive.

[0027] The bearing seat 708 mounted on the mounting frame 701 is rotatably connected to the transmission shaft 706, and both ends of the transmission shaft 706 are provided with worm gears 705. The servo motor 707, which is connected to the transmission shaft 706, is fixedly connected to the mounting frame 701. This allows the servo motor 707 to drive the transmission shaft 706 to rotate smoothly on the mounting frame 701 when it is running, thereby rotating the worm gears 705 and transmitting power to the worm wheel 704. The worm wheel 704 then rotates on the mounting frame 701 and the screw 8, achieving stable threaded transmission. This allows the entire drive component 7 to slide on the connecting rod 9 of the middle seat 5 with the stamped slide block 6, ensuring smooth operation.

[0028] During use, the material to be stamped is placed on the worktable 3 and its position is adjusted. Then, the servo motor 707 is turned on, and through the cooperation of the transmission shaft 706 and the worm gear 705, the worm wheel 704 is driven to rotate in the sleeve on the mounting frame 701 and on the screw 8. This causes the driving component 7 to slide along the connecting rod 9 of the middle seat 5, stamping the material on the worktable 3 and completing the stamping process. During stamping, the push rod 703 on the mounting frame 701 will first engage with the moving frame 401. Upon contact, the moving frame 401 slides on the mounting rod 403 and compresses the support spring 404. The moving frame 401 moves down with the top material block 402, forming a cavity for stamping the material on the worktable 3, ensuring the completion of the stamping. Subsequently, when the stamping slider 6 moves up with the driving component 7, the pushing rod 703 separates from the moving frame 401. The support spring 404 drives the moving frame 401 to reset with the top material block 402. During the reset process, the top material block 402 pushes the stamped workpiece onto the worktable 3.

[0029] Finally, it should be noted that the above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
