Description

Technical Field

[0001] The utility model relates to the technical field of metal surface heat treatment hangers, in particular to a metal surface heat treatment hanger that prevents deformation and bending. Background Art

[0002] Metal surface heat treatment is an important metal processing technology, which is mainly used to improve the surface properties of metal materials. The following are several common surface heat treatment methods: Carburizing: Place the low-carbon steel workpiece in a carburizing medium and heat it to a high temperature and keep it for a certain period of time, so that carbon atoms penetrate into the surface of the steel workpiece to improve its hardness and wear resistance; Induction heating quenching: Use the principle of electromagnetic induction to quickly heat the workpiece surface to the quenching temperature, and then quickly cool it to obtain a high-hardness martensitic structure; Flame quenching: Use a combustible gas flame to quickly heat the workpiece surface, and then cool it to achieve the purpose of surface hardening; Chemical heat treatment: Place the workpiece in a specific medium for heating and insulation, so that the active atoms in the medium penetrate into the surface of the workpiece, thereby changing the chemical composition and structure of the workpiece surface, and then changing its performance. Chemical heat treatment is also called surface quenching because it changes the surface structure of the steel and also changes its chemical composition; resistance heating quenching: a voltage of less than 5 volts is applied to the workpiece through the electrode, a large current flows through the contact point between the electrode and the workpiece, and a large amount of resistance heat is generated, so that the surface of the workpiece is heated to the quenching temperature, and then the electrode is removed, the heat is transferred into the interior of the workpiece and the surface is rapidly cooled; there are also methods such as electrolytic heating quenching and laser heat treatment.

[0003] In the existing metal surface heat treatment hanger, when the metal part is hung on the hanger, the whole metal part is suspended in the air. Therefore, when the metal part is heated, the metal part is extremely easy to deform and bend under the action of gravity, resulting in poor quality, especially thinner metal parts are more prone to deformation.

[0034] The anti-deformation clamping assembly includes a spring 7 detachably mounted on a support rod 8, one end of the spring 7 is fixedly connected to a mounting disk 14, one end of the mounting disk 14 is welded to a clamping plate, the end of the spring 7 away from the clamping plate is welded to a mounting plate 9, and the mounting plate 9 is fixed to the support rod 8 by bolts; the elastic force of the spring 7 is used to drive the clamping plate to clamp the metal part, thereby preventing the metal part from being suspended as a whole, and greatly reducing the deformation amplitude of the metal part when heated.

[0035] The clamping plate is set as a first clamping plate 6, and a first groove 61 is provided on the first clamping plate 6. The inner wall shape of the first groove 61 can be determined according to the surface shape of the heat-treated metal (if the metal part is rod-shaped, the first groove 61 can be arc-shaped).
