Gear preliminary forged piece water-spraying descaling device

Abstract

The invention discloses a device for descaling by spraying water on a preliminary forging of a gear, which belongs to the technical field of gear production. Including the control structure, the circulating water tank, the conveying tunnel on the circulating water tank, the chain conveying structure arranged in the conveying tunnel, the feeding structure arranged at the front end of the chain conveying structure, and the unloading structure arranged at the rear end of the chain conveying structure , at least one spray head arranged in the conveying tunnel, a filtered water tank arranged on the circulating water tank, a high-pressure pump arranged on the circulating water tank and at least one photoelectric sensor arranged on the conveying tunnel, the filtered water tank communicates with the circulating water tank , the filtered water tank is connected to the water inlet of the high-pressure pump through a pipeline, and the water outlet of the high-pressure pump is connected to the sprinkler head through a pipeline with a solenoid valve. The sprinkler head is located directly above the chain plate conveying structure and in front of each sprinkler head Correspondingly, there is a photoelectric sensor below, the photoelectric sensor is flush with the workpiece on the chain plate conveying structure, and the control structure is electrically connected with the photoelectric sensor, high-pressure pump and solenoid valve.

Description

technical field [0001] The invention belongs to the technical field of gear production, and in particular relates to a device for descaling by spraying water on a preliminary forging of a gear. Background technique [0002] At present, the traditional forging process in the gear forging industry is pre-forging-hot trimming-final forging-cold trimming to obtain rough products. After pre-forging, a layer of oxide skin is formed on the surface of the gear, and after final forging, the oxide skin is embedded in the surface of the gear to form oxidation pits. , the tooth surface finish is very poor, which will lead to the loss of tooth profile accuracy in severe cases 。 [0003] In the prior art, it is usually necessary to remove the scale after the pre-forging process, and a rotating iron brush is usually used to remove the scale on the surface of the gear. But the applicant finds that it has the following problems: 1. The irregular shape of the gear is not suitable for steel ...
