Description

Technical Field

[0001] The present invention belongs to the technical field of intelligent numerical control pressure system platforms, and in particular relates to a reciprocating extrusion intelligent numerical control pressure system platform and a method for using the same. Background Art

[0002] Biodegradable zinc alloys require a certain level of plasticity, toughness, and mechanical support during their application. Therefore, they need to be strengthened and toughened. This is achieved through the use of Serve Plastistic Deformation (SPD). SPD can significantly refine the grain size, reducing the internal structure of the material to submicron or even nanoscale levels. This improves both the strength and toughness of the biodegradable zinc alloy. Serve Plastistic Deformation techniques primarily include: uniform cross-section angular extrusion, high-pressure torsion, and reciprocating extrusion (also known as cyclic extrusion compression, CEC). Reciprocating extrusion allows for the desired material refinement by easily adjusting parameters such as the number of extrusion passes, temperature, and rate.

[0003] While the patent applications CN110919006A, entitled "A Controllable Isochannel Angular Extrusion Device and Method for Compressed Metal Powder," and CN110125203A, entitled "Metal Material Movable Reciprocating Extrusion Device Suitable for a Unidirectional Four-Column Hydraulic Press," both mention controlling parameters such as pressure and temperature during the extrusion process, they still suffer from limited mold clamping space, difficulties in mold clamping and adjustment, low control system integration, difficulty in achieving real-time monitoring and control of the extrusion process state, and complex and low-versatility device structures, requiring specialized equipment and hindering industrialization. Existing technologies are unable to achieve coordinated and matched visual monitoring of multiple physical parameters, including pressure, temperature, velocity, and displacement, making it difficult to scientifically understand the state of the biodegradable zinc alloy during the extrusion process and precisely control its formation.

[0062] Example 2

[0063] The reciprocating extrusion intelligent numerical control pressure system platform of the present invention, when used:

[0064] First, the displacement parameters of the mold control platform 3 are set in the PC 5. The platform fine displacement control system 2 raises or lowers the mold control platform 3 to a specified height according to the set parameters, and then moves forward so that the mold control platform 3 extends out of the base to the specified position.
