Description

Technical Field

[0001] This utility model specifically relates to a drive motor for a punch press. Background Technology

[0002] Stamping equipment, as an important metal forming tool, is widely used in industries such as automobile manufacturing, home appliance production, aerospace, and electronics. The core working principle of traditional stamping equipment is to drive a slide block to move up and down using the rotational inertia of a flywheel, thereby completing the stamping operation on the workpiece. This design relies on the mass and rotational speed of the flywheel to store enough kinetic energy to overcome the material's resistance and achieve the required stamping torque. However, with the continuous development of industrial manufacturing technology, traditional stamping equipment has gradually revealed some significant problems and limitations in practical applications: First, it is bulky and heavy. To obtain sufficient stamping torque, traditional stamping equipment usually 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 scenarios. Second, it lacks control precision. In traditional stamping equipment, the stamping torque directly depends on the mass and rotational speed of the flywheel, making it difficult to precisely adjust key parameters during the stamping process. Traditional equipment struggles to meet the high precision and consistency requirements of modern industrial production.

[0003] This utility model was developed precisely because of the aforementioned shortcomings. Utility Model Content

[0004] The purpose of this invention is to overcome the shortcomings of the existing technology and provide a simpler, more compact, and more precise drive motor for punch presses.

[0005] This utility model is achieved through the following technical solution:

[0006] This utility model provides a drive motor for a punch press, comprising: a frame, on which a rotating component capable of rotating relative to the frame is provided, the rotating component being a magnetic conductor and having a rotor assembly thereon, and a stator assembly on the frame; the rotor assembly comprising a plurality of permanent magnets disposed on the rotating component and distributed circumferentially, the rotating component being a magnetic conductor; and the stator assembly comprising a stator core connected to the frame and distributed circumferentially corresponding to the permanent magnets, and a winding coil wound on the stator core, wherein when the winding coil is energized, it generates an interactive magnetic field with the permanent magnets to drive the rotating component to rotate.

[0007] As described above, the drive motor for the punch press has a stator ring connected to the frame, and the stator core is mounted on the stator ring, with the two forming an integral structure.

[0008] As described above, in the drive motor for a punch press, the permanent magnet is a thin sheet, and the rotating component is provided with an embedding groove for embedding the permanent magnet.

[0009] In the drive motor for the punch press described above, the width of the permanent magnet gradually decreases from near the rotation center to far away from the rotation center.

[0010] The drive motor for the punch press described above has a brake device on the frame that can prevent the rotating parts from rotating.

[0011] As described above, the drive motor for a punch press includes a braking device comprising a brake seat connected to the frame, a brake assembly on the brake seat, and a braking assembly comprising two clamping members located on both sides of a rotating component and slidably connected to the brake seat, a drive device connected to the brake seat and used to push the clamping members closer together to clamp the rotating component, and the braking assembly further comprising two swinging members located on both sides of the rotating component, the middle of the swinging members being rotatably connected to the brake seat, one end of the swinging members being rotatably connected to the drive device and the other end of the drive device being rotatably connected to the clamping members.

[0012] As described above, the drive motor for a punch press has a brake base with multiple brake assemblies distributed circumferentially.

[0014] As described above, the drive motor for a punch press includes a heat dissipation device comprising a heat dissipation shroud located on one side of the rotating component, the heat dissipation shroud forming a heat dissipation cavity, a heat dissipation vent on the heat dissipation shroud connecting the heat dissipation cavity to the outside, and a fan connected to the heat dissipation vent corresponding to the heat dissipation vent.

[0015] As described above, the drive motor for the punch press has a hollowed-out slot on the rotating part, and the hollowed-out slot is located at the position corresponding to the heat dissipation cavity.

[0016] Compared with the prior art, the present invention has the following advantages:

[0017] The drive motor for punch presses of this invention can achieve stable and precise control. By adjusting the working parameters of the coil winding, such as the current variation pattern, frequency and current power, the speed, inertia and torque of the flywheel can be controlled more precisely. It can be applied to stamping equipment to drive the flywheel to rotate. Not only is the structure compact and stable, but this precise control capability also enables the equipment to adapt to a variety of different stamping needs, improving production efficiency and product quality.

[0022] The utility model will be further described below with reference to the accompanying drawings:

[0023] The orientations described in this utility model specification, such as "up," "down," "left," "right," "front," and "back," are based on the orientations in the accompanying drawings and are intended to facilitate the description of the relationships between the various components. They do not indicate the unique or absolute positional relationships between the various components, but are merely one embodiment of the utility model and are not a limitation on its implementation.

[0024] This embodiment describes 1. a drive motor for a punch press, such as... Figure 1 and Figure 2 As shown, it includes a frame 1, on which a rotating component 2 capable of rotating relative to it is provided, the rotating component 2 being a magnetic conductor and having a rotor assembly 300 thereon, and a stator assembly 400 on the frame 1.

[0025] Among them, such as Figure 3 and Figure 4As shown, the rotor assembly 300 includes several permanent magnets 3 disposed on the rotating member 2 and distributed circumferentially, wherein the rotating member 2 is a magnetic conductor; the stator assembly 400 includes a stator core 41 connected to the frame 1 and distributed circumferentially corresponding to the permanent magnets 3, and a winding coil 42 wound on the stator core 41. When the winding coil is energized, it generates an interactive magnetic field with the permanent magnets 3, which drives the rotating member 2 to rotate. The stator assembly generates a rotating magnetic field through a rotating circuit, and through the interaction of the magnetic field with the rotor assembly, the rotor assembly rotates in the direction of the rotating magnetic field of the stator assembly. The above structure allows for precise control of the rotational torque of the rotating component 2 by controlling the frequency and power of the winding coil 42. This precise and stable control of the rotational law of the rotating component 2 can be applied to control the rotation of the flywheel of the punch press, thereby enabling precise and stable control of the moving speed and impact torque of the punch press's punching slide. This type of motor can be organically integrated into the punch press's base and flywheel, eliminating the need for additional rotor housings, stator supports, and other structures, resulting in a more compact equipment structure.

[0026] In detail, such as Figure 4 As shown, a stator ring 4 is connected to the frame 1, and the stator core 41 is disposed on the stator ring 4, and the two are an integral structure.

[0027] Preferably, in order to achieve better magnetic conductivity between the permanent magnet 3 and the rotating component 2, such as Figure 4 As shown, the permanent magnet 3 is a thin sheet, and the rotating part 2 is provided with an embedding groove 21 for embedding the permanent magnet 3.

[0028] In detail, such as Figure 3 and Figure 4 As shown, the permanent magnet 3 gradually decreases in width from near the rotation center to far away from the rotation center, forming a roughly trapezoidal structure, while the stator core 41 and the winding coil 42 also have matching trapezoidal structures.

[0029] As a preferred option, such as Figure 1 and Figure 2 As shown, the frame 1 is equipped with a brake device 5 that can prevent the rotating part 2 from rotating, thereby facilitating the deceleration and stopping of the rotating part 2.

[0030] As a preferred embodiment of the braking device 5, such as Figure 1 and Figure 2As shown, the braking device 5 includes a brake seat 51 connected to the base 1. The brake seat 51 is equipped with a brake assembly 50. The brake assembly 50 includes two clamping members 52 located on both sides of the rotating member 2 and slidably connected to the brake seat 51, and a driving device 53 connected to the brake seat 51 for pushing the clamping members 52 closer together to clamp the rotating member 2. The driving device 53 pushes the two clamping members 52 closer or further apart, thereby achieving the braking function. In detail, as... Figure 1 and Figure 2 As shown, the brake assembly 50 also includes two swing members 54 located on both sides of the rotating member 2. The middle of each swing member 54 is rotatably connected to the brake seat 51. One end of each swing member 54 is rotatably connected to the drive device 53, and the other end of the drive device 53 is rotatably connected to the clamping member 52. The drive device 53 can be a general cylinder, hydraulic cylinder, or linear motor, etc. One swing member 54 is rotatably connected to the drive device 53 body, and the output shaft of the drive device 53 is rotatably connected to the other drive device 53. Thus, when the drive device 53 extends or retracts its output shaft, it can push the two clamping members 52 closer to or further away from each other. In order to improve braking performance without increasing the volume of a single drive device 53, in this embodiment, the brake seat 51 is provided with multiple brake assemblies 50 distributed circumferentially.

[0031] As a preferred implementation method, such as Figures 3 to 4 As shown, the rotating component 2 is connected to a heat dissipation device 6, which can dissipate heat for the rotating component 2 and the stator assembly, thereby improving the performance and stability of the equipment.

[0032] As a preferred embodiment of the heat dissipation device 6, such as Figures 3 to 4 As shown, the heat dissipation device 6 includes a heat dissipation cover 61 located on one side of the rotating component 2. The heat dissipation cover 61 forms a heat dissipation cavity 60. The heat dissipation cover 61 is provided with a heat dissipation port 62 connecting the heat dissipation cavity 60 to the outside. The heat dissipation cover 61 is connected to a fan 63 that is correspondingly arranged with respect to the heat dissipation port 62. In order to improve the ventilation and heat dissipation effect, preferably, the rotating component 2 is provided with a hollowed-out slot 22, which is located at the corresponding position of the heat dissipation cavity 60.

It should be noted that those skilled in the art can make various modifications and improvements without departing from the structure of this utility model, and these should also be considered within the scope of protection of this utility model.
