The flattening cavity has a pressure-receiving cavity one and a pressure-receiving cavity two arranged vertically and connected to each other, and the opening size of the pressure-receiving cavity one is larger than the opening size of the pressure-receiving cavity two. This utility model uses a combination of a flattening mold and a hydraulic press to perform multiple flattening and cold working hardening, allowing copper that has softened due to high temperatures to harden and strengthen again.

Description

Technical Field

[0001] This utility model relates to the field of mold technology, and in particular to a mold and system for flattening copper materials. Background Technology

[0002] Copper, with its superior thermal conductivity, excellent heat storage capacity, outstanding corrosion resistance, superior processing and welding properties, and good compatibility with coolants, has become the gold standard material for core heat-conducting components such as cold heads and radiators in high-performance liquid cooling systems. It offers the optimal balance of heat dissipation efficiency, system reliability, and long-term durability, despite its relatively high cost and weight. In applications demanding ultimate heat dissipation performance, copper's advantages are irreplaceable.

[0003] Copper materials can achieve excellent metallurgical bonding at the interface (high density, high strength connection) through diffusion welding; however, copper grains will grow significantly under the high temperature and pressure of diffusion welding. The coarse grains will directly lead to severe softening of the material, decreased toughness (increased brittleness), and may reduce fatigue strength and corrosion resistance. Utility Model Content

[0019] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0020] like Figure 1 and Figure 2 As shown, a flattening copper material mold and system includes a flattening cavity, wherein the flattening cavity has a pressure-receiving cavity 3 and a pressure-receiving cavity 4 that are arranged vertically and connected to each other, and the opening size of the pressure-receiving cavity 3 is larger than the opening size of the pressure-receiving cavity 4.

[0021] When in use, product 1 is first placed in the flattening cavity of the flattening mold 2, and then pressure is applied multiple times by a hydraulic press, so that the copper body hardens and strengthens again due to the amount of deformation.

[0022] The second pressure chamber 4 opens from the bottom of the second pressure chamber 3 and extends downward in an inverted stepped shape.

[0023] The opening of the pressure chamber 3 is rectangular.

[0024] The opening of the pressure chamber 24 is rectangular.

[0025] The four corners of the first pressure chamber 3 and the four corners of the second pressure chamber 4 are all chamfered. The purpose of these chamfers is to release stress, enhance structural stability, prevent cracking after stamping, reduce interference between the product edges and mold corners, and create a tool avoidance position. After the stamping process is completed, it is convenient to remove the product.

[0026] The chamfer structure is a rounded chamfer structure.

[0027] The flattened copper material mold has openings 5 ​​on both sides, and the openings 5 ​​extend into the pressure chamber 3.

[0028] A copper flattening mold system includes a copper flattening mold and a lifting block. The lifting block is positioned above the mold and connected to a stamping machine. The descent pressure of the lifting block can be adjusted within the flattening range of 3.0-4.0 MPa. The system is configured as follows: First, the pressure is set to 3.0-3.5 MPa; the product is placed in the flattening mold and the press is activated. Second, the pressure is set to 3.0-3.5 MPa; the product is rotated 180° and placed in the flattening mold, and the press is activated. Third, the pressure is set to 3.5-4.0 MPa; the product is placed in the flattening mold and the press is activated. Fourth, the pressure is set to 3.5-4.0 MPa; the product is rotated 180° and placed in the flattening mold, and the press is activated. The flattening amount is 0.1-0.15 mm for the 3.0-3.5 MPa setting and 0.2-0.25 mm for the 3.5-4.0 MPa setting.
