Abstract
Description
Technical Field
[0001] This utility model relates to the field of stamping equipment technology, specifically to a high-rigidity automatic cutting machine. Background Technology
[0002] Patent CN116274819A discloses a precision forging machine with a novel worm gear and electronic mold height. The machine includes a frame, a motor mounted on the top of the frame, a flywheel mounted on the side of the frame, an eccentric shaft rotatably connected to the frame, a clutch between one end of the eccentric shaft and the flywheel, a connecting rod connected to the middle of the eccentric shaft, a slider mounted below the connecting rod, and a slider spindle between the connecting rod and the slider. The structure, driven by the flywheel and the eccentric shaft, achieves reciprocating stamping action. The disadvantages of this structure are as follows:
[0003] 1) Generally, flywheels or flywheels in combination with gears are used to transmit and convert kinetic energy. If only gear sets are used for kinetic energy conversion, the installation space and gear ratio are also limited.
[0004] 2) When the kinetic energy demand is high, the strength requirements of the parts also increase, and the size of the parts and the installation space also increase accordingly, resulting in a large space occupation. Utility Model Content

[0009] A transmission unit that is connected to the power unit, the transmission unit including an eccentric shaft;
[0010] The swing arm is connected to the transmission unit and performs a reciprocating swing motion under the drive of the eccentric shaft.
[0011] The movable part is rotatably connected to the swing arm, and the movable part can make vertical lifting and lowering movements within the frame under the drive of the swing arm.

[0027] The embodiments of the present utility model will now be described in detail with reference to the accompanying drawings. To make the objectives, technical solutions and advantages of the embodiments of the present utility model clearer, the technical solutions of the embodiments of the present utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are some embodiments of the present utility model, but not all embodiments.
[0028] Therefore, the following detailed description of the embodiments of the present invention provided in conjunction with the accompanying drawings is not intended to limit the scope of the claimed invention, but merely to illustrate selected embodiments of the invention. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without inventive effort are within the scope of protection of the present invention.
[0029] like Figures 1-6 As shown, the high-rigidity automatic cutting machine in this embodiment is mainly composed of a frame 1, a power unit mounted on the frame 1, a transmission unit connected to the power unit, a swing arm connected to the transmission unit, and a movable part rotatably connected to the swing arm. The power unit is used to output power. The swing arm makes a reciprocating swinging motion under the drive of the eccentric shaft 9. The movable part can make a vertical lifting motion within the frame 1 under the drive of the swing arm to realize the stamping action. The gear ratio is combined with the lever structure. The two mechanisms cooperate with each other and are used in the transmission structure of the equipment to enable the equipment to achieve the required kinetic energy.
[0030] Specifically, the power unit includes a motor 2, a transmission belt 3, and a flywheel 4. The motor 2 and the flywheel 4 are connected by the transmission belt 3. The motor 2 is located above the frame 1, and the flywheel 4 is located on one side of the frame 1.
[0031] Furthermore, the transmission unit includes an eccentric shaft 9, a first transmission unit 5, a second transmission unit 6, and a third transmission unit 8. The first transmission unit 5 is connected to the flywheel 4 and is in transmission cooperation with the second transmission unit 6. The second transmission unit 6 is in transmission cooperation with the third transmission unit 8. The third transmission unit 8 is connected to the eccentric shaft 9.
[0032] The first transmission unit 5 includes a first shaft connected to the flywheel 4 and a first gear mounted on the first shaft. The second transmission unit 6 includes a second shaft and a second gear and a third gear 7 mounted on the second shaft. The third transmission unit 8 meshes with the third gear 7. The second gear meshes with the first gear. The first shaft and the second shaft are arranged in parallel. The third gear 7 is smaller than the second gear, and the first gear is also smaller than the second gear. Kinetic energy is converted and transmitted through the gear ratio.
[0033] Furthermore, the swing arm includes a lower swing arm 11 connected to the eccentric shaft 9 and an upper swing arm 10 rotatably connected to the frame 1. The upper swing arm 10 and the lower swing arm 11 are connected by transmission and can both swing. Here, the swing arm is driven by the eccentric shaft 9. The movement of the upper swing arm 10 and the lower swing arm 11 generates displacement, which drives the moving part to move. The upper swing arm 10 and the lower swing arm 11 are conventionally connected by a shaft and a cover plate. When the eccentric shaft rotates, it drives the lower swing arm 11 to swing and slide with the upper swing arm 10, and pushes the upper swing arm 10 to generate actuation. The upper swing arm 10 is connected to the frame as a fulcrum. When the lower swing arm 11 pushes the upper swing arm 10, the rear end swings at a certain angle, causing the front end of the upper swing arm 10 to swing synchronously.
[0034] Furthermore, the movable part includes a connecting rod 13 and a slider 14. One end of the connecting rod 13 is rotatably connected to the upper swing arm 10, and the other end of the connecting rod 13 is rotatably connected to the lower swing arm 11. The movable part is restricted to vertical lifting and lowering movement within the space of the frame 1.
[0035] It should be noted that the aforementioned components that require rotational movement are connected to the frame 1 via a shaft structure.
[0036] All descriptions herein may be presented in any suitable order.

Of course, variations of these preferred embodiments will be readily apparent to those skilled in the art. The inventors intend that those skilled in the art may use these variations as appropriate, and the inventors indicate that the utility model can be implemented in other ways than those specifically described herein.
