Description

Technical Field

[0001] This utility model relates to the field of servo press technology, and in particular to a pressure control device for a precision servo press with multi-sensor feedback. Background Technology

[0002] A servo press is an intelligent pressure device that uses a servo motor drive control system. The servo press is programmable and can arbitrarily set the slider stroke, speed, pressure and multi-segment composite pressing curves through a PLC or industrial panel PC. It supports precise stopping at a set position at a constant speed, stopping when the pressure reaches the preset pressure value, and precise control of the pressing depth. The servo press has technical features such as high precision and closed-loop control, high efficiency and energy saving, and functional integration.

[0003] Servo presses offer high control precision through their drive structure. For example, a novel precision servo press body (Chinese Patent Publication No. CN219467098U) utilizes a servo motor and multi-stage reduction gears to address diameter differences, avoiding excessively long transmission chains while ensuring effective force amplification. This device boasts efficient space utilization, a compact structure, and a smaller body, making it suitable for various applications. However, while this optimization of the servo press's drive structure enhances output force and control precision, it lacks targeted monitoring and feedback control during the pressing process, thus compromising the overall working accuracy. Particularly concerning is the uneven material distribution caused by the servo press's single-point pressing mechanism during the mutual compression of two plates, leading to reduced overall precision.

The eight circular multi-layer stacked piezoelectric ceramic units 4 are evenly distributed with the drive end of the power body 1 as the center. A dustproof cloth 14 is provided between the fine-tuning drive base plate 2 and the extrusion base plate 6.

[0021] As a preferred embodiment, the support structure further includes: a body support 8, a heightening support 9, and a platform base 10; the body support 8 is installed on the rear wall of the power unit 1, the heightening support 9 is installed on the rear wall of the body support 8, the platform base 10 is installed on the lower wall of the heightening support 9, and four stable heightening feet 15 are installed on the lower wall of the platform base 10, and the platform base 10 is provided with four anti-scratching rounded corners.

[0023] Working Principle: When using this device, the operator first connects an external AC power supply to provide energy to the electrical equipment within, including the power unit 1, eight circular multilayer stacked piezoelectric ceramic units 4, eight fine-tuning pressure sensors 5, and four platform pressure sensors 12. Simultaneously, the operator connects a matching controller to these electrical devices, providing control and operational logic. A computer is also connected to the controller to provide computing power for the circular multilayer stacked piezoelectric ceramic units 4 and to store data for the various electrical devices.

[0024] The operator places the material to be compressed on the upper wall of the platform support plate 13. At this time, the four platform pressure sensors 12 are compressed by the gravity of the material, and the four platform pressure sensors 12 transmit the change data back to the controller.

[0025] A dustproof cloth 14 is provided between the fine-tuning drive base plate 2 and the extrusion base plate 6 to effectively ensure the sealing between the two and ensure the precision of the electronic components.

[0026] Next, the operator starts the power unit 1 to begin operation, while the eight circular multi-layer stacked piezoelectric ceramic units 4 reset to their original lengths. The drive end of the power unit 1 extends, causing the fine-tuning drive base plate 2 to move downwards. The fine-tuning drive base plate 2, the spherical universal support column 3, and the extrusion base plate 6 move downwards until the extrusion base plate 6 contacts the material. When the extrusion base plate 6 extrudes the material, the force feedback from the extrusion valve acts on the eight fine-tuning pressure sensors 5. Due to the uneven surface of the material, the extrusion base plate 6 can swing around the spherical universal support column 3. As extrusion continues, the eight fine-tuning pressure sensors 5 receive different forces. These eight fine-tuning pressure sensors 5 are bidirectional pressure sensors, capable of detecting both pressure and tension. The device can then provide feedback based on the data detected by the fine-tuning pressure sensors 5. When a fine-tuning pressure sensor 5 detects pressure, the corresponding circular multi-layer stacked piezoelectric ceramic unit 4 extends until all eight fine-tuning pressure sensors 5 detect the same data. This achieves precise control of the precision servo press.

Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
