Description

Technical Field

[0001] This utility model relates to the field of automotive radiator technology, specifically to a motherboard molding machine for automotive radiators. Background Technology

[0002] The mainboard of the radiator is one of the most important components in the automotive radiator assembly. Currently, domestic and foreign companies still use a three-stage stamping process using a conventional manual punch press, which includes: first, preliminary shaping of the sheet metal using a punch press; second, processing of the water chamber teeth by pressing; and finally, completing the stretching, flanging, or punching process. This traditional method has the following prominent problems: 1. The mold design is fixed, and it can only produce motherboards of a single specification. When it is necessary to switch product types, the entire mold must be replaced, resulting in low production flexibility and long adjustment cycles.

[0003] 2. Reliance on manual operation, high labor demand, and frequent mold changes increase mold manufacturing and maintenance costs. Furthermore, multiple punch presses placed side-by-side occupy significant space, resulting in high overall equipment investment.

[0004] 3. Sequential processing leads to discontinuous connections between processes, requiring multiple clamping and transfer of boards, resulting in a slow overall production pace. The average forming time for each motherboard is long, making it impossible to meet the demands of mass production.

[0005] 4. Excessive human intervention can easily introduce operational errors, resulting in poor consistency in motherboard dimensions and affecting the sealing and durability of the heatsink assembly.

[0006] 5. During punch press operation, manual feeding and unloading poses a risk of pinching injuries, and there is a lack of automated protection mechanisms.

[0007] 6. The multiple independent punch presses are scattered, resulting in a large equipment footprint and low factory space utilization.

[0008] These defects severely restrict the efficient development of the automotive parts industry, and there is an urgent need for an integrated, adjustable automated device to solve these problems. Utility Model Content
