Description

Technical Field

[0001] The utility model relates to the technical field of gear processing, in particular to a carburizing heater for gear processing. Background Art

[0002] Carburizing heaters are a type of industrial heating equipment specifically designed to perform the carburizing process. Carburizing is a metal surface hardening process that causes the surface layer of low-carbon steel to absorb carbon at a certain temperature, thereby increasing the surface hardness and wear resistance while maintaining the toughness of the internal material.

[0003] According to the patent application number CN202123127712.4, a dust suction pipe is provided on one side of the furnace body, and a baffle is provided between the dust suction pipe and the furnace body. By providing the baffle, the heat inside the furnace body is prevented from being dissipated when the workpiece is infiltrated. After the infiltration is completed, when the temperature inside the furnace body is lowered, the baffle is pulled to one side by the slider, and then the residual dust inside the furnace body is sucked into the dust collecting box by the exhaust fan for easy collection. The workpiece to be carburized is placed on a placing plate, and the rotating shaft is driven by a motor to rotate, so that the workpiece is carburized evenly and the carburizing quality is improved. A filter box is provided on one side of the exhaust pipe to filter the internal gas and protect the surrounding environment.

[0004] In the above patent, the residual dust inside the furnace body is sucked into the dust collecting box by an exhaust fan for collection, but it is difficult to clean the carbon black on the inner wall of the furnace body. The carbon black adheres to the inner wall of the furnace body and is difficult to fall off. If it is not handled in time, it will affect the heating temperature inside the furnace body. Therefore, in response to the above shortcomings, the present utility model makes the following improvements. Utility Model Content

[0005] In view of the deficiencies in the prior art, the utility model provides a carburizing heater for gear processing, which solves the problems mentioned in the background technology.

[0007] The cleaning mechanism includes a threaded rod rotatably arranged inside the mounting plate, and the top of the threaded rod surface is threadedly connected to a sliding sleeve, the surface of the sliding sleeve is fixedly provided with a fixed boss, and the surface of the fixed boss is sleeved with an annular block, a cleaning frame is provided inside the furnace body, and the outer surface of the cleaning frame is fixedly connected to a scraper, and the surface of the annular block is fixedly connected to the inner wall of the cleaning frame through a connecting rod.

[0008] Preferably, a heating shell is provided on the surface of the furnace body.

[0009] Preferably, sealing plates are slidably provided inside the groove and on both sides of the mounting plate, a collecting box is movably provided on the top surface of the bottom plate and below the groove, and scrapers are provided on both sides of the inside of the groove.

[0010] Preferably, electric push rods are rotatably provided on both sides of the heating shell via fixed shafts, and the protruding ends of the electric push rods are rotatably connected to one side of the sealing plate via a connecting shaft.

[0011] Preferably, a storage plate is slidably provided between the two sides of the inner wall of the furnace body, and a through hole adapted to the threaded rod is opened inside the storage plate.

[0012] Preferably, a cover plate is movably provided on the top surface of the furnace body.

[0013] Beneficial effects

[0014] The utility model provides a carburizing heater for gear processing. Compared with the prior art, it has the following advantages:

[0015] (1) The carburizing heater for gear processing can, through the setting of the cleaning mechanism, drive the scraper bar to move downward along the inner wall of the furnace body through the cleaning frame after the gear processing is completed, thereby scraping off the carbon black attached to the inner wall of the furnace body, which is convenient for subsequent unified collection.

[0016] (2) The carburizing heater for gear processing can seal the groove by controlling the relative movement of two sealing plates, thereby preventing heat loss inside the furnace body during gear processing. By controlling the two sealing plates to move away from each other, the groove can be opened when cleaning the furnace body, facilitating the rapid discharge of waste materials.
