Its versatility and high production efficiency make it suitable for a wide range of applications, including cutting, punching, blanking, bending, riveting, and forming. It applies strong pressure to metal blanks, causing them to plastically deform and fracture, ultimately creating parts. A press provides the pressure required for product processing and typically consists of a pressure head and a lifting mechanism that raises and lowers the pressure head.

[0003] The applicant's previous patent application, with publication number CN209426248U, disclosed an ultra-quiet press. During the actual production of the machine, the applicant discovered that its guiding function was poor and the stepping effect was inaccurate during the manufacturing process. Therefore, on this basis, the applicant improved the guiding structure therein and proposed the technical solution of the present application. Utility Model Content

[0004] The purpose of the utility model is to provide a servo press in order to overcome the shortcomings and deficiencies of the prior art.

[0005] A servo press includes a base, on which a lifting component is provided. The lifting component includes a column and a base that is lifted and lowered on the column. The base is provided with a motor, the motor is connected to a drive shaft, the drive shaft extends to the outside of the base and is fixedly sleeved with a balance plate. First guide columns are provided on both sides of the balance plate, and the other end of the first guide column extends into the base and is slidably connected thereto. The arrangement of the balance plate and the first guide column achieves significant improvements in stability, guiding accuracy, balance, and work efficiency, and enhances structural stability. By providing the combination of the column and the base in the lifting component, a more solid support structure is provided, which can effectively withstand large pressure loads and improve overall mechanical stability. The first guide column enables the lifting and lowering movement of the pressure head to be carried out with less friction and resistance, thereby improving the accuracy of the guidance and ensuring that each stamping or forming operation achieves the desired effect. The design of the balance plate enables the press to better distribute its weight and force generated during operation, reduce tilting or shaking problems caused by lifting and lowering movement, and achieve more stable operation. The simple design and clear structure make daily maintenance and adjustment more convenient, help reduce equipment failure rate, and thus improve production efficiency.

[0006] Preferably, a first connecting hole is provided at the bottom of the base, a mounting block is provided above the first connecting hole, a second connecting hole corresponding to the first connecting hole is provided on the mounting block, and the end of the first guide column passes through the first connecting hole and is slidably connected to the second connecting hole. Through this connection method, the guiding performance, stability, maintainability and other aspects of the servo press are significantly improved. The first guide column is slidably connected through the first connecting hole and the second connecting hole to form a stable guiding structure, ensuring that the guide column maintains a good centering state when the press is operating, thereby achieving more precise lifting and positioning effects. The setting of the mounting block makes the connection between the guide column and the base more stable, and can effectively resist vibrations and impacts that may occur during operation, thereby improving the stability and safety of the entire machine.

[0007] Furthermore, sliding sleeves are provided on both sides of the base, and the base is slidably connected to the column through the sliding sleeves. The base is slidably connected to the column through the sliding sleeves, so that the longitudinal movement of the base can be realized, thereby increasing the flexibility of the equipment in different processing methods and material processing, and adapting to various process requirements. The design of the sliding sleeve can effectively reduce friction resistance and reduce wear during movement, thereby extending the service life of the guide assembly and other related structures and reducing maintenance costs.

[0008] Furthermore, a guide hole is provided on the sliding sleeve, a fixed plate is provided on the top of the column, a second guide column is fixedly provided on the fixed plate, and the other end of the second guide column extends into the guide hole and is slidably connected thereto.

The combination of the fixed plate and the second guide column makes the guiding structure less likely to deform and provides a more stable support. Through the design of the fixed plate and the second guide column, the distribution of force inside the machine can be improved, so that the lifting components can obtain more uniform force during the movement, thereby improving the stamping efficiency and forming accuracy.

[0012] Furthermore, the motor is a servo motor. Driven by the servo motor, precise control of the lifting and lowering action of the press can be achieved. This is particularly important for production and manufacturing that requires high-precision operations, and can ensure the stability of the processing process and the consistency of the product.

[0013] Preferably, the base is also provided with a panel for controlling the movement of the lifting components. The panel allows the operator to control and adjust the equipment more conveniently during operation, improves the convenience of operation, and enhances the user experience. Through the control buttons or switches on the panel, the operator can quickly stop or adjust the movement of the lifting components, so as to take quick measures in the event of an abnormality to ensure the safety of the staff.

[0014] The beneficial effects of the present invention are as follows: the arrangement of the balance plate and the first guide column has achieved significant improvements in stability, guiding accuracy, balance and work efficiency, and the structural stability is enhanced. By establishing a combination of a column and a base in the lifting component, a more solid support structure is provided, which can effectively withstand a larger pressure load and improve the overall mechanical stability.
