Problems solved by technology

[0005] (1) The cleaning steps are cumbersome and complicated
[0006] (2) The area required for cleaning castings is large
[0007] (3) The cycle of cleaning castings is long
According to years of experience, it takes at least 8 hours for castings of bolsters and side frames to reach the operating temperature under the condition of natural wind cooling, which restricts the increase of production capacity;
[0008] (4) Products are prone to quality problems
After unpacking, the high-temperature castings are stacked together and cooled under natural conditions. The castings are easily deformed and the cooling is uneven.
[0009] (5) The labor intensity of workers is high and there are potential safety hazards
When cleaning castings, it must be turned over several times to remove all the defects of the castings, which greatly increases the labor intensity, and also increases the probability of safety accidents during the turning process

Embodiment Construction

[0044] Below in conjunction with accompanying drawing and specific embodiment the present invention is described in further detail:

[0045] like Figure 1~5The shown truck bolster side frame cooling and cleaning system includes a platform 3, a manipulator 4, a dust removal device 11, a fan 18, and passes through a feeding area 12, a cooling area 13, a casting riser cutting area 7, and a casting defect cleaning area. 8. The accumulation type suspension chain 5 in the shot blasting area 9 and the off-line area 10 also includes an accumulation type suspension chain driver 25, wherein the hook 6 of the accumulation type suspension chain 5 is connected to the accumulation type suspension chain driver. Driven by 25, it can shuttle and move between the feeding area 12, the cooling area 13, the casting riser cutting area 7, the casting defect cleaning area 8, the shot blasting area 9 and the off-line area 10;

[0046] The manipulator 4 is used to transport the truck bolster side fra...

Abstract

The invention relates to a railway wagon swing bolster and side frame cooling and cleaning method and system. The railway wagon swing bolster and side frame cooling and cleaning method and system changes a traditional casting cleaning mode into a mode of hanging and transporting castings through accumulation suspension chains to on-line complete the steps such as casting cooling, casting head cutting, flaw clearing and abrasive blasting and accordingly to achieve clean casting processing. The railway wagon swing bolster and side frame cooling and cleaning method and system has the advantages of simple process, small space occupation, high production efficiency and low labor intensity.

Description

technical field [0001] The invention relates to the technical field of cooling and cleaning systems for large steel castings of railway freight cars, in particular to a cooling and cleaning method and system for railway freight car bolster side frames. technical background [0002] Bolsters and side frames are the key parts of the running part of railway wagons. During the production process of bolsters and side frame castings of railway wagons in my country, the traditional cleaning method of laying the castings on the site is adopted after the bolsters and side frame castings are solidified. [0003] The traditional cleaning method is: after the castings are poured and solidified, shake out the sand on the shakeout machine, then hoist the sand box and castings to the cleaning site together, lift the upper sand box, turn over the lower sand box and castings, and lift the castings and castings respectively. Lower the sand box, arrange the castings neatly, and cool them natur...
