[0002] As an important forging equipment, screw press is widely used in the field of metal forming processing. During the operation of traditional screw press, the running-in effect between its screw pair (including screw and nut) directly affects the operating efficiency and accuracy of the equipment. After installing or replacing key components, early screw presses lacked effective running-in methods and it was difficult to quickly reach the best working state.

[0003] Traditional running-in methods mostly rely on long periods of no-load operation or simple load impact, which is not only time-consuming and labor-intensive, but also unable to accurately control the force and energy parameters during the running-in process, resulting in uneven running-in results. During the running-in process, the stability and safety of the equipment are also difficult to fully guarantee, and problems such as uneven wear of parts and loose connections are prone to occur, which may even cause equipment failures and affect production progress. At the same time, the energy conversion efficiency of traditional screw presses is low and cannot fully realize their working potential.

[0004] In addition, as the manufacturing industry's requirements for metal forming accuracy and efficiency continue to increase, the market is increasingly in need of a device that can quickly, accurately and efficiently run-in a screw press. The device should not only solve the problems of the traditional running-in method, but also have the advantages of simple structure, easy operation, low cost and strong versatility, so that it can be widely used on screw presses of different specifications and models, thereby promoting the further development and upgrading of screw press technology.

[0049] 1. Effective buffering and precise reset

[0050] Effective buffering: The return spring in the buffer unit can effectively absorb and buffer the impact force generated during the running-in process. When the slider drives the upper plate to move downward and contact the impact plate, the return spring is compressed, thereby reducing the impact on the equipment components and protecting the equipment from damage.

[0051] Precise reset: The elastic force of the reset spring ensures that the upper plate can be quickly and accurately reset after each impact. This quick reset helps to maintain the continuity and stability of the running-in process and improve the running-in efficiency.

[0052] 2. Accurate positioning and stable connection

[0053] Precise positioning: The positioning groove on the spring positioning column matches the positioning column on the upper plate to ensure that the upper plate always maintains precise alignment during movement. This precise positioning helps to improve the running-in accuracy and ensure uniform wear of the spiral pair.

[0054] Stable connection: The spring positioning column is installed on the bottom plate to form a stable support structure. This design ensures that the buffer unit will not move or loosen when subjected to impact force, improving the stability of the equipment.

[0055] 3. Simple structure and easy maintenance

[0061] 5. Improve running-in quality and extend equipment life

[0062] Improve running-in quality: Through effective buffering and precise positioning, the buffer unit can ensure that the force of each component is even during the running-in process, reducing the problem of uneven wear caused by uneven force. This helps to improve the running-in quality and extend the service life of the equipment.

[0063] Extend equipment life: The buffering effect of the return spring reduces the direct impact between components, thereby reducing the wear rate of the components. This not only extends the service life of the equipment, but also reduces the cost caused by frequent maintenance and replacement of parts.

[0064] The present invention also relates to a screw press, comprising the screw press force energy running-in device, wherein the upper plate of the screw press force energy running-in device is installed on the upper part of the frame, and the bottom plate is installed on the lower part of the frame.

[0067] The bottom plate is fixedly connected to the frame by bolts, and a lubrication groove is provided on the surface of the bottom plate (3) and is connected to an external lubrication system.

[0068] The pneumatic control system is integrated with a pressure sensor to monitor the striking force of the slider in real time and feed back the force to the speed regulating module of the drive motor.

[0069] The working principle of the present invention is:

[0070] Working principle of the force and energy running-in device of the screw press

[0071] (1) Starting the drive mechanism

[0072] 1. Drive motor starts: The drive motor is connected to the flywheel through a V-belt, and after starting, it drives the flywheel to rotate in the opposite direction. The function of the flywheel is to store and release energy to provide power for the entire system.

[0073] 2. Flywheel and transmission screw linkage: The flywheel is connected to the transmission screw through a spline sleeve. The rotation of the flywheel drives the transmission screw to rotate together. The forward and reverse rotation of the transmission screw will drive the slider to move up and down in a straight line.

[0074] (2) Movement of the slider

[0075] 1. Up and down movement of the slider: A nut that matches the transmission screw is fixed inside the slider. When the transmission screw rotates, the nut drives the slider to make linear motion in the vertical direction. The up and down movement of the slider is precisely guided by the guide connection unit to ensure the stability and linearity of the movement.

[0076] 2. Function of the guide connection unit: The screw of the connection bolt passes through the bottom plate, impact plate and upper plate in sequence to ensure the precise alignment between the upper plate, impact plate and bottom plate. The bottom plate through hole on the bottom plate and the stepped hole on the impact plate reduce the friction between the bolt head and the bottom plate and impact plate. The sliding hole on the upper plate cooperates with the end of the threaded rod to further reduce the friction between the threaded rod and the upper plate.

[0077] (3) Function of the buffer unit

[0078] 1. Buffering impact force: When the slider drives the upper plate to move downward and contacts the impact plate, the return spring is compressed, effectively absorbing and buffering the impact force generated during the running-in process, protecting the equipment from damage.

[0079] 2. Accurate reset: The elastic force of the reset spring ensures that the upper plate can be quickly and accurately reset after each impact. This quick reset helps to maintain the continuity and stability of the running-in process and improve the running-in efficiency.

[0080] 3. Precise positioning: The positioning groove on the spring positioning column cooperates with the positioning rod on the upper plate to ensure that the upper plate always maintains precise alignment during movement. This precise positioning helps to improve the accuracy of running-in and ensure uniform wear of the spiral pair.

[0081] (4) Application of pneumatic control system

[0082] 1. Return of the slider: The pneumatic control system includes a cylinder and a solenoid valve. When the slider needs to return, the cylinder pushes the friction plate to rotate clockwise through the air intake, so that the slider can quickly return to the top dead center position.

[0083] 2. Feedback from pressure sensor: The pneumatic control system is integrated with a pressure sensor to monitor the impact force of the slider in real time and feed the data back to the speed control module of the drive motor. The speed control module adjusts the speed of the drive motor according to the feedback data to ensure that the impact force of the slider remains within the optimal range.

[0084] (5) Lubrication system support

[0085] 1. Function of lubrication groove: The bottom plate is fixedly connected to the frame by bolts, and a lubrication groove is provided on the surface of the bottom plate, which is connected to the external lubrication system. The lubrication groove ensures good lubrication between the moving parts, reduces friction and wear, and increases the service life of the equipment.

[0086] (6) Overall running-in process

[0087] 1. Start of the running-in process: After the drive motor is started, the flywheel begins to rotate, storing and releasing energy. The transmission screw is linked to the flywheel through the spline sleeve, driving the slider to move up and down in a straight line.

[0088] 2. The running-in process: The slider drives the upper plate to move downward and contact the impact plate to complete a strike. The reset spring in the buffer unit absorbs the impact force and protects the equipment. The upper plate quickly resets after each impact to ensure the continuity of the running-in process.

[0089] 3. Control of the running-in process: The pneumatic control system monitors the impact force of the slider in real time through the pressure sensor and feeds back to the speed control module of the drive motor to ensure that the impact force remains within the optimal range. The lubrication system provides continuous lubrication through the lubrication groove to reduce friction and wear between components.

[0090] (7) Completion of the running-in process

[0091] 1. End of the running-in process: When the running-in of the spiral pair reaches the expected effect, the drive motor stops working, the flywheel stops rotating, the transmission screw stops rotating, and the slider stops moving. The buffer unit and the guide connection unit ensure that the positions of the various components of the equipment are accurate and the equipment is stable when it is stopped.

[0092] 2. Equipment maintenance: After the running-in process is completed, the equipment can be maintained and inspected. The guide connection unit and the buffer unit have a simple structure, which is easy to disassemble and replace parts, ensuring the long-term stable operation of the equipment.

[0093] Through the above working principle, the screw press force energy running-in device can effectively improve the running-in accuracy and efficiency, reduce the wear of components, extend the service life of the equipment, and ensure that the screw press operates in the best condition.
