Description

Technical Field

[0001] The invention relates to the technical field of grinding wheel production, in particular to a circulating grinding wheel baking device and process. Background Art

[0002] The manufacturing process of traditional grinding wheels is usually divided into the following steps: 1. Batching, weighing the required raw materials according to the formula requirements; 2. Mixing, mixing the abrasive and other materials in order and time according to the process requirements to form the molding material; 3. Molding, using a press and a mold to press the molding material into the required shape of the grinding wheel blank; 4. Drying, which is divided into natural drying under natural environment and artificial baking drying by artificial heating, as well as continuous drying using both; 5. Firing, in this process, the ceramic grinding wheel is called sintering, and the resin grinding wheel is called hardening. vulcanization, the rubber grinding wheel is called vulcanization, the whole process is completed by the temperature changes of heating, constant temperature and cooling in a curve; six, processing, the process of using a lathe or grinder to process the outer circle, plane and aperture of the fired embryo into a finished product, some of which also require filling, sulfurization, wax infiltration, etc.; seven, inspection and stamping, the appearance, size, hardness, balance, strength, etc. of the product must be strictly inspected to ensure that it meets the requirements of the standards, and qualified products must be stamped with the seals required by the standards, and product certificates must be printed by batch; eight, packaging and warehousing, qualified products must be packaged as required, and then stored in the warehouse.

[0003] Among them, the molding process of the grinding wheel usually adopts the pressing molding method. In the molding process of the ceramic grinding wheel, the grinding wheel blank after pressing contains a certain amount of water, and its strength is low. During transportation and reprocessing (such as bonding and blank repair), it is easy to deform or break due to low strength. Therefore, in order to improve the strength of the blank after molding, baking and drying are required. After baking and drying to remove most of the free water in the grinding wheel blank, the blank can shrink less in the subsequent firing process, so that the blank can be quickly heated during the firing stage, and the product will not deform or crack, which can not only ensure the firing quality but also shorten the firing cycle, improve efficiency and reduce energy consumption.

[0004] The patent with announcement number CN115615159B discloses a grinding wheel drying equipment with high space utilization, including a drying box and a placement unit, the four inner corners of the drying box are each provided with a guide rail in a vertical state, the placement unit is arranged on the four guide rails, the placement unit includes a first sliding frame, a second sliding frame and a supporting assembly, the sliding direction of the second sliding frame is perpendicular to the sliding direction of the first sliding frame, the supporting assembly is slidably arranged on the second sliding frame, and a positioning assembly for fixing the first sliding frame is provided on the outer side of the drying box.

However, in the technical solution of the patent, the drying box for the grinding wheel needs to wait for cooling down and taking out the grinding wheel after each drying before the next drying can be carried out, and needs to be heated up again, which is time-consuming, labor-intensive and consumes more energy.
