Description

Technical Field

[0001] The utility model relates to the technical field of hardware product processing, in particular to a heat treatment device for processing hardware products. Background Art

[0002] Hardware products are auxiliary and accessory products used in daily life and industrial production. In the early days, they were mostly made of metal materials such as gold, silver, copper, iron, and tin, hence the name. In addition to various metal materials, non-metallic materials such as plastics and glass fibers are also widely used. Generally speaking, the hardware industry is running well, with obvious growth momentum in domestic and foreign sales, rapid growth in imports and exports, and rapid improvement in various economic indicators. Hardware products play an important role in human survival and development.

[0003] Heat treatment is required during the processing of hardware products. According to a heat treatment device for processing hardware products disclosed in patent number CN 218666136U, a heating wire is installed at the top of the inner part of the box, and two fans are installed at the top of the inner part of the box. The fans blow air into the inner part to heat the heating wire to achieve heat treatment of the clamped hardware products. After the heat treatment is completed, the heat-treated workpiece is cooled by the cooperation of a condenser, a water pump and a cooling elbow. However, the box of the existing device can only clamp and fix one hardware product at a time, and can only heat treat one hardware product at a time, so the heat treatment efficiency of the hardware products is extremely low; the existing device The heating tube is installed at the top of the box body, and the fan blows hot air from top to bottom to the upper part of the workpiece, resulting in poor heat treatment effect on the lower part of the hardware product, affecting the heat treatment quality of the hardware product; and the existing device sets the heat treatment and cooling of the hardware product in the box body. After the workpiece is heat treated, the box body is in a high temperature state for a certain period of time, the cooling time of the hardware product is long, and the next hardware product needs to be heated again when heat treated, resulting in a long heating and cooling time, which greatly reduces the heat treatment efficiency of the hardware product. For this reason, we propose a heat treatment device for processing hardware products. Utility Model Content
