Description

TECHNICAL FIELD

[0001] The utility model relates to punch die field, especially is the vertical row punch die of production VC piece upper cover. BACKGROUND

[0002] Punch die is a kind of process equipment commonly used in industrial production, which processes metal or non-metal materials into parts of required shape by using the cavity and male die inside the die through pressure. Punch die has the advantages of high production efficiency, high material utilization rate and high machining precision, and is widely used in automobile, electronic, home appliance and other industries. With the progress of science and technology and the development of industry, the requirements for punch die are also getting higher and higher, not only to meet the basic processing needs, but also to have high precision, high efficiency, high stability and other characteristics.

[0003] VC vapor chamber is an important component for heat dissipation, widely used in mobile phones, computers, servers, graphics cards, etc., playing a role in heat dissipation. VC vapor chamber is usually composed of an upper cover and an upper cover, both of which are metal sheets, and a vacuum cavity is formed between the upper cover and the upper cover, usually made of copper. Its working principle is based on the gas-liquid phase change principle: when heat acts on one side of the chamber, the working liquid in the cavity absorbs heat and evaporates rapidly, the volume expands rapidly, and the gas phase cooling medium fills the entire cavity rapidly; the steam moves to the cooler area under the action of slight pressure difference, where it condenses into liquid and releases heat; then, the condensed cooling liquid flows back to the heating area through the microstructure capillary channel, completing the cycle. This process is repeated in the cavity, achieving efficient conduction and uniform distribution of heat.

[0004] The existing VC piece upper cover punch die has the following defects:

[0005] 1) Traditional punch die often uses multiple independent stations to complete different processes, which not only increases production cost, but also reduces production efficiency;
