Description

Technical Field

[0001] The utility model belongs to the technical field of removing oxide scales, and in particular relates to a mechanism for removing oxide scales from a columnar workpiece after high-temperature heating. Background Art

[0002] The oxide scale produced by metal after high temperature heating will seriously affect the quality of subsequent forging and other processing processes. Therefore, it is necessary to remove the oxide scale to improve the quality of subsequent processing. However, the metal after high temperature heating is difficult to touch, so it is not easy to remove the oxide scale.

[0003] Patent document 112024815A discloses a forging scale removal process and device, the forging scale removal device comprises a frame, an annular tube and a telescopic cylinder arranged on the frame, the two ends of the annular tube are respectively rotatably installed on the frame via a rotating shaft, the annular tube is a hollow structure, an annular cavity is arranged inside the annular tube, a plurality of groups of water outlet holes are arranged at intervals on the left outer edge surface of the annular tube, and the water outlet holes are connected with the annular cavity; a water inlet is respectively arranged on the top and bottom of the right side of the annular tube, the water inlet is connected with the annular cavity, each group of the water inlet is connected with a joint, and each group of the joints is connected with a water pipe; a connecting plate is arranged at the outer end of a group of rotating shafts, the bottom of the connecting plate is vertically connected to the rotating shaft, the end of the telescopic cylinder is rotatably connected to the frame, and the output shaft of the telescopic cylinder is rotatably connected to the top of the connecting plate.

[0004] The above scheme sprays water on the forgings in all directions to cool down and reduce dust during the forging process, so as to achieve the technical effect of removing oxide scale. However, cooling the forgings itself will affect the difficulty of forging and even the final quality of forging. The scheme of spraying water to cool down during the forging process may reduce this effect, but it also limits the conditions of use. It cannot be used in a relatively closed forging environment and is not suitable for use before forging. In addition, spraying water to cool down the forgings can quickly differentiate the oxide scale, but it cannot guarantee that the differentiated oxide scale can be completely separated from the forging. The detached oxide scale generally cannot be properly collected and processed at the forging position, and is prone to secondary attachment. Utility Model Content
