Description

Technical Field

[0001] The invention relates to the technical field of rivet fastener production, in particular to a heat treatment device for manufacturing aviation rivets. Background Art

[0002] A rivet is a nail-shaped object with a cap at one end. It uses its own deformation or interference fit to connect the riveted parts during riveting. There are many types of rivets and they are not restricted by form. Rivets will undergo local deformation after riveting, so they need to be heat treated during the production and processing process to achieve better toughness and higher mechanical strength.

[0003] The heat treatment process of rivets generally includes three processes: heating, heat preservation, and cooling. Sometimes there are only two processes, heating and cooling. These processes are interconnected and cannot be interrupted. Aviation rivets have different sizes. When heat treating smaller rivets, it is usually necessary to use a tray as a carrier to hold the rivets, and use a conveyor belt to transport or directly place the tray containing the rivets in a heat treatment furnace for heat treatment. Due to the simple structure of the tray, the relative positions of the rivets placed in the tray cannot be changed during heat treatment, resulting in different heating uniformity of rivets placed in different positions on the tray, thereby affecting the heat treatment quality of the rivets.
