Description
Technical Field
[0001] The utility model relates to the technical field of metal thermal processing, in particular to an annealing mechanism for printing machine castings. Background Art
[0002] A printing press is a machine that prints text and images. In the manufacturing process of a printing press, most of the required plates are installed by welding or bolting. The required castings need to be heat treated during the processing. The heat treatment of metals is to heat the metal or alloy workpiece to a suitable temperature in a certain medium, keep it at this temperature for a certain period of time, and then cool it at different speeds in different media. The performance of the metal material is controlled by changing its surface or internal microstructure. Annealing mainly refers to a heat treatment process in which the material is exposed to high temperature for a long time and then slowly cooled.
[0003] The utility model of China is disclosed as a metal heat treatment annealing device with the publication number of CN214270957U. The utility model discloses a metal heat treatment annealing device, which includes an annealing structure arranged in an operating box; the annealing structure includes: a temperature detector, a feeding door, an exhaust pipe, an air storage box, an electric control valve, an air delivery pipe, a plurality of flame heads, a cooling component and a placement rack. Through the built-in cooling component, water vapor can be evenly transported to cool the workpiece in all directions. The processing temperature of the workpiece is constantly observed through the built-in temperature detector to prevent the workpiece from being scrapped, thereby effectively solving the technical problems of uneven annealing commonly existing in existing annealing devices, which makes it easy for different parts of the metal to cause stress differences, resulting in its quality being affected, increasing the occurrence of workpiece scrapping, and low annealing efficiency.
[0004] In the process of implementing the utility model, at least the following problems exist in the technology. When using the above-mentioned annealing mechanism for printing machine castings, the device places the heat-treated metal on the upper end of the placement rack, and then uses a flamethrower to heat and anneal the metal. However, this causes one side of the placed metal to be directly heated by the flamethrower, and then the heating temperature of the other side will be lower, so it will cause uneven heating temperatures on both sides of the annealed metal, affecting the quality of metal production. In addition, in the cooling process, water is heated into water vapor to cool the workpiece. Although water vapor can prevent a large amount of water from directly impacting the workpiece, resulting in fine lines in the subsequent quenching of the workpiece, the cooling effect of water vapor is poor and requires a long time. Therefore, an annealing mechanism for printing machine castings is now proposed. Utility Model Content
