Detailed Description
The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments.
Referring to fig. 1-2, a cold press molding device for a vitrified grinding wheel comprises a base 1, a mold block 2, a compact 3, a hydraulic cylinder 4 for driving the compact 3 to move up and down, and a feeder (not shown), and is characterized in that: the die block 2 is rotatably mounted on the base 1 through a transmission mechanism, the transmission mechanism comprises a driving motor 51, a worm 52 and a first gear 53 which are mounted on the base 1, the first gear 53 is coaxially connected below the die block 2, and the first gear 53 is rotatably mounted on the base 1; the output end of the driving motor 51 is connected with a second gear 54, the worm 52 is coaxially connected with a third gear 55, the third gear 55 is externally meshed with the second gear 54, and the worm 52 is meshed with the first gear 53; the top of the die block 2 is provided with a circular groove 21, and a fixing column 22 is fixedly arranged at the center of the circular groove 21; the pressing block 3 is located above the die block 2, an orifice aligned with the fixed column 22 is formed in the center of the pressing block 3, the size of the orifice is adaptive to the size of the fixed column 22, when the pressing block 3 is pressed against the die block 2, the fixed column 22 blocks the orifice, the feeding machine is arranged above the pressing block 3, and a discharge hole of the feeding machine is communicated with the orifice. In the embodiment, (1) the first gear 53 drives the die block 2 to synchronously rotate in the circumferential direction, so that the raw material of the ceramic grinding wheel in the circular groove 21 is uniformly paved in the circular groove 21 without manual flattening, and the working efficiency is improved; (2) during cold pressing, the pressing block 3 moves into the circular groove 21 under the action of the hydraulic cylinder 4, and the top of the fixed column 22 is inserted into the orifice to realize plugging of the orifice and avoid interference between the fixed column 22 and the pressing block 3; (3) the dimensions of the pressure piece 3 are adapted to the dimensions of the circular groove 21.
