Spring double-layer tray, multicolor paint dipping unit and bogie spring paint dipping production line

Abstract

The invention provides a spring double-layer tray, a multi-color paint dipping unit and a bogie spring paint dipping production line, and belongs to the field of bogie spring production. The spring double-layer tray comprises a feeding unit, a spring preheating unit, a multi-color paint dipping unit, a line changing unit and a paint dipping spring drying unit; a pre-paint-dipping spring is fed to a preset position of a spring double-layer tray through a feeding and discharging mechanical arm and conveyed to a spring preheating unit along with the spring double-layer tray to be heated and dehumidified, paint dipping of a first preset color is achieved in a first paint dipping groove of a multi-color paint dipping unit, paint dipping of a second preset color of a lower layer part of the spring is achieved in a second paint dipping groove, and paint dipping of a second preset color of the spring is achieved. Paint dipping of a third preset color of the remaining springs is achieved in a third paint dipping groove; and the paint-dipped spring enters the paint-dipped spring drying unit to be dried. According to the bogie spring paint dipping production line, during paint dipping, the springs borne on the same tray are subjected to multi-color paint dipping, the production efficiency of spring paint dipping is improved, and meanwhile the bogie assembling efficiency and the efficiency of assembling a whole locomotive are greatly improved.

Description

technical field [0001] The invention belongs to the technical field of rail vehicle bogie spring production, and in particular relates to a spring double-layer tray, a multi-color paint dipping unit and a bogie spring dip paint production line. Background technique [0002] In the bogies of rail vehicles, the bogie springs can attenuate vehicle vibrations and ease impacts during the operation of rolling stock, and balance the weight distribution of rolling stock among the wheelsets. As a key component of the weight bearing capacity of rolling stock, the performance of the bogie spring determines the safety, stability, comfort and low noise of the operation, and plays a key role in the performance of the train. [0003] After the bogie spring is completed, it needs to be sprayed with a top coat, and after drying, it is inspected to pass the inspection and enters the bogie assembly process. Railway freight car bogie springs come in various specifications, and need to be spray...

AI Technical Summary

Problems solved by technology

[0005] Due to the many specifications and models of bogie springs and different spraying colors, the current spring vertical dip coating process can only dip-coat bogie springs of one specification at the same time, and the production efficiency is low
