Description

Technical Field

[0001] The utility model relates to the technical field of metal annealing, in particular to an annealing furnace for cold-deformed metal. Background Art

[0002] Cold deformation, also known as cold working, refers to the deformation or processing of metal below the recrystallization temperature, such as cold drawing or cold stamping of steel. Although the deformation of metal below the recrystallization temperature is also in a heated state, it is not hot deformation or hot working. For example, the processing of pure iron at 400°C is still cold working because the lowest recrystallization temperature of pure iron is 450°C. Similarly, although the deformation of metal above the recrystallization temperature does not involve heating the metal or is at room temperature, it is not cold deformation or cold working. For example, the processing of low-melting-point metals such as lead and tin at room temperature is hot working because the lowest recrystallization temperatures of lead and tin are -63°C and -96°C respectively;

[0003] Annealing is a metal heat treatment process, which means heating the metal slowly to a certain temperature, maintaining for a sufficient time, and then cooling at an appropriate speed. Generally speaking, annealing is a heat treatment process for materials, including metal materials and non-metal materials. Moreover, the purposes of annealing of new materials also have similarities and differences with those of traditional metal annealing.

[0004] In the existing technology, there are problems that it is inconvenient to take out steel parts during annealing and a large amount of heat is lost during the annealing process, which will cause workers to be scalded and the taking time to be long when taking steel parts, and finally lead to low annealing efficiency of steel parts. For this reason, we propose an annealing furnace for cold-deformed metal. Content of the Utility Model

[0006] To achieve the above purpose, the utility model provides the following technical solution: An annealing furnace for cold-deformed metal, including a furnace body. An annealing cavity is opened at the upper end of the furnace body. The annealing cavity communicates with two symmetrically arranged chutes opened on the furnace body. A water adding assembly is arranged at the front end of the furnace body. A controller is arranged on the front side of the water adding assembly. A basket lifting mechanism is arranged on the furnace body. A water discharging assembly is arranged at the lower end of the furnace body. The basket lifting mechanism includes mounting frames connected to both sides of the furnace body. A stepping motor is connected inside each mounting frame.

[0013] 1. The furnace body, annealing cavity, sliding groove, basket lifting mechanism, support and controller are provided to complete putting the steel part into the basket body. Next, the controller supplies power to the stepping motor. At this time, the output end of the stepping motor drives the rotating shaft to rotate, thereby driving the rotating disc to rotate. At this time, the rotating disc drives the pull rope to unwind. At this time, the basket body descends. At this time, the slider slides on the guide post. At this time, the steel part in the basket body can perform the annealing action. When the annealing action is completed, the controller can control the stepping motor again.

[0014] 2.
