Description

Technical Field

[0001] The present invention particularly relates to a novel stamping device. Background Art

[0002] Stamping equipment, as an essential metal forming tool, is widely used in industries such as automotive manufacturing, home appliance production, aerospace, and electronics. The core operating principle of traditional stamping equipment is to use the rotational inertia of a flywheel to drive the slider's upward and downward motion, thereby completing the stamping operation on the workpiece. This design relies on the flywheel's mass and rotational speed to store sufficient kinetic energy to overcome the material's resistance and achieve the required stamping torque. However, with the continuous advancement of industrial manufacturing technology, traditional stamping equipment has gradually exposed some significant problems and limitations in practical applications. First, it is bulky and heavy. To achieve sufficient stamping torque, traditional stamping equipment typically requires a heavy flywheel. This design not only increases the overall weight of the equipment but also makes it difficult to reduce its size, limiting its application in space-constrained or weight-sensitive applications. Second, it suffers from insufficient control accuracy. In traditional stamping equipment, the stamping torque is directly dependent on the flywheel's mass and rotational speed, making it difficult to precisely adjust key parameters in the stamping process (such as stamping force and stamping speed). Traditional equipment struggles to meet the high precision and consistency requirements of modern industrial production.

[0003] The present invention is just produced based on above-mentioned deficiency. Summary of the Invention

[0015] Compared with the prior art, the present invention has the following advantages:

[0016] 1. Precise control: By adjusting the working parameters of the coil winding, such as the current variation law, frequency and current power, the speed, inertia and torque of the flywheel can be controlled more accurately, thereby achieving precise and stable control of the slider seat movement speed and impact torque. This precise control capability enables the equipment to adapt to a variety of different stamping requirements and improve production efficiency and product quality.

[0017] 2.

[0024] The invention will be further described below with reference to the accompanying drawings:

[0025] The directions described in the specification of the present invention, such as "up", "down", "left", "right", "front", "back", etc., are based on the directions in the accompanying drawings and are intended to facilitate the description of the relationship between the various components. They do not indicate the unique or absolute positional relationship between the various components. They are only one of the implementation methods of the invention and are not a limitation on its implementation method.

[0026] This embodiment introduces a new type of stamping equipment, such as Figure 1 and Figure 2As shown, this new stamping equipment includes an organic base 1, and the machine base 1 is provided with a slider seat 2 that can slide up and down relative to it to realize opening and closing of the mold. In detail, the machine base 1 is generally provided with a lower mold seat, and the slider seat 2 is provided with an upper mold seat. The upper mold seat is located above the lower mold seat and is arranged correspondingly up and down. Therefore, when the slider seat 2 slides downward, the upper mold seat and the lower mold seat are closed to realize the stamping function. The machine base 1 is also provided with a flywheel 3 that can rotate relative to it. A linkage structure 4 is provided between the flywheel 3 and the slider seat 2 for driving the latter to slide up and down when the former rotates. A driving structure 5 for driving the flywheel 3 to rotate is provided between the machine base 1 and the flywheel 3. Figure 3 As shown, the drive structure 5 includes a rotor assembly and a stator assembly. The rotor assembly includes a plurality of permanent magnets 51 disposed on the flywheel 3 and distributed circumferentially. The flywheel 3 is a magnetic conductor, that is, the flywheel 3 and the permanent magnets 51 form an outer rotor. The stator assembly includes a stator 52 connected to the base 1, stator teeth 53 distributed circumferentially on the stator 52 and corresponding to the permanent magnets 51, and coil windings 54 wound around the stator teeth 53. When energized, the coil windings 54 generate an interactive magnetic field with the permanent magnets 51 to drive the flywheel 3 to rotate. Specifically, the stator assembly generates a rotating magnetic field through a rotating circuit. The interaction with the magnetic field generated by the rotor assembly causes the rotor assembly to rotate in the direction of the stator assembly's rotating magnetic field. This structure can precisely control the frequency of the coil windings 54 and the operating power of the coil windings 54, thereby precisely and stably controlling the movement speed and impact torque of the slider seat 2.

[0027] As a preferred embodiment of the linkage structure 4, Figure 4 As shown, the linkage structure 4 includes a rotating shaft 41 coaxially connected to the flywheel 3 and a crank member 42 rotatably connected to the slider seat 2. The crank member 42 is provided with a matching hole 43 for the rotating shaft 41 to pass through. The rotating shaft 41 is provided with an eccentric wheel 44 which is located at a corresponding position of the matching hole 21 and is eccentrically arranged. In this way, when the rotating shaft 41 rotates, the eccentric wheel 44 can cooperate with the matching hole 21 to push the slider seat 2 to slide up and down.

[0028] As a preferred embodiment, Figure 1 and Figure 2 As shown, the base 1 is provided with a brake device 6 capable of preventing the flywheel 3 from rotating, thereby facilitating the flywheel 3 to slow down and stop rotating.

[0029] As a preferred embodiment of the brake device 6, Figure 2 and Figure 3As shown, the brake device 6 includes a brake seat 61 connected to the machine base 1, and a brake assembly 60 is provided on the brake seat 61. The brake assembly 60 includes two clamping members 601 located on both sides of the flywheel 3 and slidably connected to the brake seat 61, and a driving device 602 connected to the brake seat 61 and used to push the clamping members 601 to approach each other and thereby clamp the flywheel 3. The driving device 602 pushes the two clamping members 601 to approach or move away from each other, thereby realizing the braking function.

[0030] In detail, Figure 2 and Figure 3 As shown, the brake assembly 60 also includes two swinging members 603 located on either side of the flywheel 3. The middle portion of the swinging member 603 is rotatably connected to the brake seat 61. One end of the swinging member 603 is rotatably connected to the drive device 602, while the other end of the drive device 602 is rotatably connected to the clamping member 601. The drive device 602 can be a conventional pneumatic cylinder, hydraulic cylinder, or linear motor. The drive device 602 body is rotatably connected to one of the swinging members 603, and the output shaft of the drive device 602 is rotatably connected to the other drive device 602. When the output shaft of the drive device 602 is extended or retracted, it can push the two clamping members 601 toward or away from each other. In order to improve braking performance without increasing the size of a single drive device 602, in this embodiment, the brake seat 61 is provided with multiple brake assemblies 60 distributed along the circumference.

[0031] As a preferred embodiment, Figures 1 to 3 As shown, the flywheel 3 is connected to a heat sink 7, which can dissipate heat for the flywheel 3 and the stator assembly, thereby improving the performance and stability of the equipment.

[0032] As a preferred embodiment of the heat dissipation device 7, Figures 1 to 3 As shown, the heat dissipation device 7 includes a heat dissipation cover 71 surrounding the rotating shaft 41. The heat dissipation cover 71 encloses a heat dissipation cavity 700. The heat dissipation cover 71 is provided with a heat dissipation outlet 701 connecting the heat dissipation cavity 700 with the outside. The rotating shaft 41 is connected to a fan 72 corresponding to the heat dissipation outlet 701. To improve the ventilation and heat dissipation effect, as a preferred embodiment, the flywheel 3 is provided with a hollow slot 31, and the hollow slot 31 is located at a position corresponding to the heat dissipation cavity 700.
