Description
Technical Field
[0001] This utility model relates to the field of stamping die technology, specifically to a stamping die for producing automobile brake discs. Background Technology
[0002] Stamping dies, also known as stamping presses or presses, are devices used to process materials under pressure. Their working principle is generally that the die drives the opening and closing of the moving die and the fixed die under the action of stamping power to cut, punch, stretch and other processes on the raw material to form stamped parts. Stamping dies are required in the production of automobile brake discs.
[0003] In the process of realizing this utility model, the inventors discovered that:
[0004] Patent document CN213645615U discloses a stamping die for producing automotive brake discs. While this die solves the problem that "existing stamping dies make it difficult to remove brake discs after stamping, resulting in time-consuming and labor-intensive processes, reduced stamping efficiency, and impact on production," it also has some drawbacks. For example, only the lower stamping die has heat sinks for heat dissipation, while the upper stamping die lacks a cooling mechanism. This results in the upper die having a significantly higher temperature than the lower die, leading to uneven thermal expansion, decreased fitting accuracy, and impact on product quality. Furthermore, the upper die, operating at high temperatures for extended periods, is prone to thermal fatigue and wear, shortening its lifespan and increasing maintenance and replacement costs. Excessive upper die temperature can also cause equipment overheating or malfunction, increasing the risk of equipment failure, affecting production safety, and potentially leading to fires or other safety accidents. Finally, excessive upper die temperature can affect the performance of the stamping material, reducing material hardness, resulting in insufficient product strength, and causing surface oxidation, thus impacting product appearance and performance and ultimately its use.
