Description

Technical Field

[0001] The utility model relates to the technical field of heat sink production, in particular to a double-station heat sink riveting die. Background Art

[0002] A heat sink is a device that dissipates heat from heat-prone electronic components in electrical appliances. It is usually made of aluminum alloy, brass, or bronze in the form of plates, sheets, or multiple sheets. Riveting is used in the production process of heat sinks. The rivets are manually placed one by one directly into the rivet holes of the heat sink, and then riveted together using a mold press or a riveting machine.

[0003] For example, a heat sink riveting die with application number CN201210403689.3 and publication date 20130116 comprises: an upper template, a movable jig, a plurality of fixed blocks, a lower template, a lower die base, a lower pad, and a lower support plate. The movable jig is arranged between the lower template and the upper template. The movable jig is provided with a jig rivet hole and a handle. Rivets are placed in the jig rivet holes. The heat sink is located at the top of the movable jig. The rivets pass through the rivet holes in the heat sink. The upper template is pressed down to rivet the rivets to the heat sink. In this way, the heat sink riveting die of the present invention separates the rivet placement and riveting processes, which can be divided into different operations to reduce the problem of rivet omission. The die and machine do not need to be shut down when placing rivets, which greatly improves equipment utilization and operating efficiency.

[0004] Due to the excessive pressure during riveting, the heat sink will be stuck on the riveting machine, which makes it inconvenient for workers to remove the heat sink. Workers need to spend a lot of effort to lift the heat sink, which is time-consuming and labor-intensive, affecting the production efficiency of the riveting machine. Therefore, it is urgent to design a double-station heat sink riveting mold to solve the above problem. Utility Model Content
