Embodiment Construction
[0024] The present invention will be further described in detail below in conjunction with the accompanying drawings and examples. The following examples are explanations of the present invention and the present invention is not limited to the following examples.
[0025] Example.
[0026] see Figure 2 to Figure 4 , the water-cooled roller table used in the heating device of the iron mold sand-coated production line in this embodiment mainly includes a roller table frame 1, a side roller body 2, a wheel shaft 3, a bearing 4, a bearing sleeve 5, a shaft sleeve 6, an end cover 7, a card Spring 8, sleeve 9, fire-stop ring 10, fire-stop groove 11 and cooling water 12.
[0027] In this embodiment, the side roller body 2 and the wheel shaft 3 are connected as a whole, the bearing 4 is installed on the wheel shaft 3, the bearing sleeve 5 is fixedly welded in the hollow rectangular tube roller frame 1, and the shaft sleeve 6 is socketed with the wheel shaft 3. The end cover 7 is fi...

The invention relates to a water-cooling roller bed for a heating device of an iron mold sand coating production line and belongs to the field of machines. The water-cooling roller bed comprises a side roller wheel body, a wheel shaft, bearings, a roller bed frame, a bearing sleeve, a shaft sleeve, an end cover, a snap spring and a sleeve. The side roller wheel body and the wheel shaft are connected into a whole, and the bearings are installed on the wheel shaft. The bearing sleeve is fixed in the roller bed frame, and the shaft sleeve is connected with the wheel shaft in a sleeving mode. The end cover is fixed to the wheel shaft, and a check ring of the snap ring is placed in a groove of the inner ring of the sleeve. The water-cooling roller bed is reasonable in structure and protected against the situation that an iron mold is heated by flames and consequently a roller wheel gets stuck and cannot rotate by being heated, and normal conveying of a roller line is guaranteed.
Description
technical field [0001] The invention relates to a water-cooled roller table, in particular to a water-cooled roller table used for a heating device of an iron mold sand-coated production line, which belongs to the field of machinery. Background technique [0002] Iron mold sand-coated casting is one of the special castings. The mold is formed by covering the inner cavity of the metal mold with a thin layer of coated sand. In the production of iron sand-covered casting, heat-cured phenolic resin sand is generally used, which generally requires a temperature of about 200°C. Therefore, both the model and the iron mold need to be heated during sand-covered molding. The heating of the model is generally electric heating, and the iron mold is generally The iron mold is heated by using the residual heat of molten iron poured into the iron mold. [0003] For some smaller or thinner castings, the waste heat generated by pouring molten iron in the iron mold may not be enough to heat ...
