[0074] Embodiment 2:

[0075] like Figure 1-8 As shown, the product to be pressed is placed on the platform plate 4, the platform plate 4 turns on the vacuum to suck the product, and the product is transported to the bottom of the upper pressing head through the Y-axis driving mechanism 1. The Y-axis driving mechanism 1 and the first Z-axis driving mechanism automatically adjust the position and height of the product.

[0076] The platform plate 4 is adjusted to be parallel to the end face of the lower pressure head 7. The pulse heating system automatically adjusts the temperature of the upper pressure head 18 and the lower pressure head 7 according to the temperature and force requirements for the product during the initial pressing. The downward pressure of the upper pressure head 18 is constantly detected by the pressure sensor 13. The pressure sensor 13 constantly feeds back the force conditions to the system. The system automatically adjusts the downward pressure to perform initial pressing on the product. During the entire initial pressing process, the initial pressing process can be automatically completed without manual operation.

[0077] Embodiment 3:

[0078] The pressure mechanism based on the cylinder multi-stage pressure control system of the present invention uses a pressure sensor 13 to constantly detect the force applied to the product by the upper pressure head 18 when pressing down. The stroke control is composed of a servo motor screw and a cylinder, which is convenient for the upper pressure head to press down the product to control the stroke and force. The buffer material feeding structure and the buffer material receiving structure are placed on the top, with a simple structure. The buffer belt is placed above the main pressure part of the product using a guide wheel structure, which plays a role in: when the product's own characteristics produce surface unevenness, the upper pressure head 18 plays a buffering role on the product when pressing down.

[0079] The lower ram fixing mounting block 6 for installing the lower ram 7 and the upper ram fixing block 16 for installing the upper ram 18 are both made of gold-plated brass. The lower ram 7 and the upper ram 18 are both made of TC4 (titanium alloy). The flatness of the contact surface between the lower ram 7 and the upper ram 18 and the product is 0.002mm. Insulated stone blocks are embedded on the two rams to fix the pulse heating wire, ensuring that the temperature of the pulse heating is better controlled and safely used, so that the accuracy of this press reaches ±15μm.

[0080] The pressure platform component is separated from the lower pressure head 7. The YZ axis of the pressure platform component is adjustable, which is convenient for adjusting the parallelism of the product during the pressure. The pressure platform component adopts a vacuum adsorption structure, the material is 440C, and it has been tempered. The product placement surface reaches 0.005mm, which avoids the accuracy of the pressure being affected and damaged due to design structural defects during the pressure.

[0081] Through the precise design of structural engineers, the pressing mechanism of the present invention can quickly complete the pressing process of the product, and the temperature and force accuracy of the pressing head are well controlled, thereby better realizing the accuracy of the product pressing process.

[0082] The above description is only a preferred embodiment of the present invention, and does not limit the patent scope of the present invention.
