Automatic coating production line for splined hub nylon layer

Abstract

The invention belongs to the technical field of splined hub nylon layer coating, and discloses an automatic coating production line for a splined hub nylon layer. A glue dipping table is fixedly arranged on the left side of a chain conveyor, a wiping table is fixedly arranged on one side of the rear side of the glue dipping table, the chain conveyor is fixedly arranged on the right side of the glue dipping table, heating furnaces are fixedly arranged on the front and rear sides of the upper part of the left end of the chain conveyor, a uniform cooling device is arranged on the right sides of the heating furnaces, a nylon powder dipping table is fixedly arranged at the right end of the chain conveyor, and a PLC control program is fixedly arranged on the rear side of the nylon powder dipping table. According to the automatic coating production line, automatic and intelligent one-time coating of the splined hub nylon layer is achieved, the coating efficiency of the nylon layer of a splined hub is improved, intelligent temperature control over the glue coating layer of the splined hub is achieved, the heating uniformity is improved, the temperature control type uniform cooling of the splined hub glue coating layer is realized, and the forming quality of the splined hub glue coating layer is improved.

Description

technical field [0001] The invention belongs to the technical field of automatic spraying of nylon layers of spline hubs, and in particular relates to an automatic coating production line of nylon layers of spline hubs. Background technique [0002] The main function of coating the inner and outer surfaces of the spline hub is: on the one hand, it avoids the direct contact between the steel parts when the spline shaft and the spline hub are mated, and plays the role of shock absorption and wear resistance; Coating nylon on the outside of the hub can improve the precision of cooperation with the oil seal, and at the same time play a rust-proof function. [0003] In the prior art, the coating of the nylon layer of the spline hub is manually applied. First, the spline hub is manually dipped in glue, and then the spline hub is heated by a heating box, and then dried by natural cooling, and finally dipped in glue. Nylon powder forms a nylon coating, the entire process takes a lo...

[0003] In the prior art, the coating of the nylon layer of the spline hub is manually applied. First, the spline hub is manually dipped in glue, and then the spline hub is heated by a heating box, and then dried by natural cooling, and finally dipped in glue. Nylon powder forms a nylon coating, the entire process takes a long time, the degree of automation is low, and the efficiency of the nylon coating on the spline hub is low; the most important thing is the heating temperature and cooling of the rubber coating on the surface of the spline hub The temperature cannot be controlled, and the spline hub rubber coating layer cannot achieve uniform cooling, resulting in a high defective rate
