Abstract

The invention provides a device and a process for the surface treatment of parts. The device comprises a transportation unit and a treatment unit, wherein the transportation unit is arranged on the upper side of the treatment unit and used for transporting a preliminarily-machined part into the treatment unit; the treatment unit comprises a cleaning pool, an air furnace, a nitriding furnace, an oxidizing furnace, a cooling chamber, an ultrasonic cleaning device, a polishing machine and an oxidation repairing furnace which are arranged in sequence; a first gas transportation pipeline communicates with a nitriding cavity and used for transporting nitrogen gas into the nitriding cavity; and a second gas transportation pipeline communicates with a cooling cavity and used for transporting protective gas into the cooling cavity. By adoption of the device and the process, the nitrogen gas is injected when the surface of the part is subjected to nitriding treatment in the nitriding furnace, thereby facilitating the flow of a nitriding salt solution in the nitriding furnace, improving the nitriding speed, and reducing the deformation; and the part is cooled in the cooling chamber which is fully filled with the protective gas, so that the surface color of the part is uniform and the deformation is little.

Description

technical field [0001] The technical field of the surface treatment process of mechanical parts involved in the present invention, in particular, relates to a component surface treatment equipment and a component surface treatment process. Background technique [0002] The functions of the car's gearbox include changing the transmission ratio; driving the car in reverse when the engine's rotation direction remains unchanged; using neutral gear to interrupt power transmission so that the engine can be aerodynamic, idle, and neutral with the transmission or perform power transmission. The gearbox mainly includes gears, shafts and pins. Among them, the pin shaft is a kind of standardized fastener, which is an indispensable workpiece for the connection between the gear and the shaft. It can be connected statically, or it can move relative to the connected part. It is mainly used for the hinge of two parts. , forming a hinge connection, reliable work, easy disassembly. [0003]...
