Description

Technical Field

[0001] This utility model relates to a linkage stamping device, belonging to the technical field of processing equipment. Background Technology

[0002] In automobile manufacturing production lines, many assembly processes require the use of stamping equipment. Existing stamping equipment typically has a fixed lower die, requiring manual loading and unloading of workpieces. This results in low automation levels and hinders the realization of automated continuous production. Utility Model Content

[0003] In view of the above-mentioned defects in the existing technology, the present invention provides a linkage stamping device with simple structure, which can significantly shorten the tooling assembly and disassembly time and facilitate automated production.

[0004] This utility model is achieved through the following technical solution: a linkage stamping device, characterized in that it includes a base, a frame mounted on the base, a hydraulic cylinder, a transmission component, a worktable, and a swing arm mechanism. A guide rail is provided on the upper part of the base at the front of the frame. The worktable is slidably mounted on the guide rail, and a lower die is fixed on the upper part of the worktable. The transmission component includes a crank arm, a crank arm rod, a connecting rod, and a guide fixing plate. The guide fixing plate is slidably mounted on two vertical guide columns, which are respectively fixed on both sides of the guide rail. The lower end of the connecting rod is fixedly connected to the upper part of the guide fixing plate. One end of the crank arm rod is hinged to the crank arm via a pin, and the other end of the crank arm rod is hinged to the upper end of the connecting rod. The upper end of the hydraulic cylinder is hinged to the hydraulic cylinder fixing seat via a pin. The lower end of the hydraulic cylinder is hinged to one end of the crank arm via a pin, and the other end of the crank arm is hinged to a slider. The slider slides in cooperation with the guide groove on the frame. The upper mold is fixed to the lower part of the guide fixing plate. There are two swing arm mechanisms, which are respectively set on the rear sides of the worktable. The swing arm mechanism includes a swing arm seat fixed on the base and a swing arm with two support arms rotatably set on the swing arm seat via a connecting rod shaft. The two support arms of the swing arm are set in an angle. One of the support arms of the swing arm is connected to the rear of the worktable, and the other support arm of the swing arm is equipped with a roller. Two vertical pressure rods are connected to the two swing arms on the guide fixing plate. The lower end of the pressure rod can contact the roller on the swing arm. A return spring connected to the swing arm is set on the connecting rod shaft.

[0005] The working principle of this utility model is as follows: The hydraulic cylinder provides power. When the cylinder rod extends, it pushes the connecting rod, guide fixing plate, and upper die downwards along the guide column via the crank arm and crank arm rod. As the guide fixing plate descends, it drives the pressure rod downwards simultaneously. The pressure rod compresses the swing arm mechanism, causing it to rotate and synchronously move the worktable backwards along the guide rail. This aligns the lower die on the worktable with the upper die below the guide fixing plate, achieving a pressing or stamping action. When the hydraulic cylinder rod retracts, the crank arm and crank arm rod pull the connecting rod, guide fixing plate, and upper die upwards along the guide column. Simultaneously, the pressure rod moves upwards, and the swing arm resets under the action of the return spring, driving the worktable forward along the guide rail, allowing the pressed workpiece to be removed from the mold, achieving rapid disassembly.

[0006] Furthermore, to ensure reliable contact between the pressure bar and the swing arm when the pressure bar is pressed down, an L-shaped pressure foot is provided at the lower end of the pressure bar.

[0007] The beneficial effects of this utility model are as follows: This utility model has a simple structure. Through the linkage of the transmission components and the swing arm mechanism, it can easily clamp or loosen the tooling, enabling rapid installation and disassembly of the tooling, saving time and effort. It can achieve automatic continuous stamping, improving production efficiency. Furthermore, the workpiece is reliably fixed during clamping, effectively preventing workpiece displacement or loosening during processing. After stamping, the worktable in this utility model can move forward synchronously along the guide rail through the reset of the swing arm, thus creating distance from the upper die. This structural design facilitates the configuration of robotic arms or robotic hands for automated loading and unloading. When the worktable moves out of the stamping area after stamping, the configured robotic arms or robotic hands can automatically unload and load the workpiece, enabling intelligent stamping and forming operations within the same cycle time, greatly improving production efficiency.

[0012] The present invention will be further described below through non-limiting embodiments and in conjunction with the accompanying drawings:

[0013] As shown in the attached figure, a linkage stamping device includes a base 14, a frame 7, a hydraulic cylinder 23, a transmission component, a worktable 16, and a swing arm mechanism. The frame 7 is mounted on the upper part of the base 14, and a guide rail 15 is provided on the upper part of the base 14 at the front of the frame 7. The worktable 16 is slidably mounted on the guide rail 15, and a lower die 17 is fixed on the upper part of the worktable 16. The transmission component includes a crank arm 22, a crank arm rod 20, a connecting rod 6, and a guide fixing plate 19. The guide fixing plate 19 is slidably mounted on two vertical guide columns 8, which are respectively located on both sides of the guide rail 15 and fixed to the base 14. The connecting rod 6 is vertically mounted on the guide fixing plate 19, and its lower end is fixedly connected to the upper part of the guide fixing plate 19. One end of the crank arm rod 20 is hinged to the crank arm 22 via a crank arm pin II 21, and the other end of the crank arm rod 20 is hinged to the upper end of the connecting rod 6. The upper end of the hydraulic cylinder 23 is hinged to the hydraulic cylinder mounting base 1 via the hydraulic cylinder pin 2. The hydraulic cylinder rod of the hydraulic cylinder 23 is hinged to one end of the crank arm 22 via the crank arm pin I4. The other end of the crank arm 22 is hinged to a slider 25. A fixing plate 5 is provided on the upper part of the frame 7 near the crank arm 22. A guide groove 26 is provided on the fixing plate 5. The slider 25 slides in cooperation with the guide groove 26. An upper mold 18 is fixed to the lower part of the guide fixing plate 19. There are two swing arm mechanisms, which are correspondingly arranged on both sides of the rear of the worktable 16. The swing arm mechanism includes a swing arm seat 10 fixed on the base 14 and a swing arm 11 rotatably mounted on the swing arm seat 10 via a connecting rod shaft 13. The swing arm 11 has two angled support arms. One of the support arms of the swing arm 11 is connected to the rear of the worktable 16, and a roller 12 is provided on the other support arm of the swing arm 11. Two vertical pressure rods 24 are connected to the guide fixing plate 19 corresponding to the two swing arms 11. The lower end of the pressure rod 24 can contact the roller 12 on the swing arm 11. A return spring 9 connected to the swing arm 11 is provided on the connecting rod shaft 13.

[0014] To ensure reliable contact between the pressure rod 24 and the roller 12, it is preferable that the lower end of the pressure rod 24 is provided with an L-shaped pressure foot. The pressure rod 24 can reliably contact the roller 12 through the L-shaped pressure foot.

[0015] When this utility model is in operation, the hydraulic cylinder 23 provides power, and the workpiece to be processed or assembled is placed on the lower die. When the hydraulic cylinder rod 3 extends, it pushes the connecting rod 6, the guide fixing plate 19, and the upper die 18 downward along the guide column 8 through the crank arm 22 and the crank arm rod 20. When the guide fixing plate 19 moves downward, it drives the two pressure rods 24 to move downward at the same time. The pressure rods 24 press down on the swing arm 11 of the swing arm mechanism. While the swing arm 11 rotates, it drives the worktable 16 to move backward along the guide rail 15 (towards the machine frame), so that the lower die 17 on the worktable 16 is aligned with the upper die 18 under the guide fixing plate 19, thereby realizing the pressing or stamping action. When the cylinder rod 3 retracts, the connecting rod 6, guide fixing plate 19, and upper mold 18 can be pulled upward along the guide column 8 by the crank arm 22 and crank arm rod 20. At the same time, the pressure rod 24 moves upward, and the swing arm 11 is reset under the action of the return spring 9 and drives the worktable 16 to move forward along the guide rail 15 to open the distance between the upper and lower molds, so that the pressed workpiece is removed from the mold and the quick disassembly is achieved.

[0016] This utility model has a simple structure, which can significantly shorten the assembly and disassembly time of tooling and improve production efficiency; it has a high degree of automation, which can reduce manual operation, reduce the labor intensity of workers, and at the same time reduce the risks of manual assembly and disassembly, thus improving production safety.

[0017] This invention can be applied to automobile manufacturing, for example, for the rapid clamping and disassembly of tooling fixtures on engine assembly lines and body welding lines, which can improve production efficiency; it can be used in machining, for example, on milling machines, lathes and other machining equipment, to quickly clamp workpieces and improve machining accuracy and efficiency; it can be used in circuit board assembly and other processes, to accurately and quickly clamp tooling, ensuring production quality and efficiency.

[0018] The other parts in this embodiment are all existing technologies and will not be described in detail here.
