Forming processing method of brick and cement prefabricated part

Abstract

The invention belongs to the technical field of brick manufacturing, and specifically relates to a forming processing method of a brick and cement prefabricated part. The forming processing method comprises the following steps of (1) mixing raw materials: uniformly mixing coal ash, coal gangue, tailing slag, chemical slag and cement so as to obtain a mixture; (2) performing compression molding: performing compression molding on the mixture prepared in the step (1) so as to form a cylindrical prefabricated block; and (3) pressing and slotting: forming an annular anti-skid groove in the surfaceof the prefabricated block prepared in the step (2), wherein the pressing and slotting process in the step (3) is cooperatively performed by a forming processing machine of the brick and cement prefabricated part. According to the forming processing method, the consistent depth of all positions of the anti-skid groove is guaranteed, the raw materials which are accumulated on both sides of the anti-skid groove can be removed, the forming quality of the anti-skid groove is increased, and cracks can be prevented from being generated on the side wall of the cylindrical brick and cement prefabricated block or in the cylindrical brick and cement prefabricated block in the slotting process.

Description

technical field [0001] The invention belongs to the technical field of cement prefabricated parts manufacturing, and in particular relates to a molding and processing method of brick cement prefabricated parts. Background technique [0002] Cement brick refers to a material that uses fly ash, coal gangue, tailings slag, and chemical slag as the main raw materials, uses cement as the coagulant, and does not undergo high-temperature calcination. After the raw material of the brick is pressed into a circular prefabricated part, it is necessary to engrave an annular anti-slip groove on the surface with a metal ring. In the actual processing process, there are the following problems when embossing and slotting the surface of the brick cement prefabricated part: (1) During the embossing process, the feeding amount of the metal ring cannot be guaranteed to be consistent, so that the depth of the anti-skid groove cannot be guaranteed to be consistent. The forming quality of the ant...

Problems solved by technology

[0004] The invention provides a molding and processing method of a brick cement prefabricated part, aiming at solving the following problems existing in embossing and slotting the surface of the brick cement prefabricated part: (1) the progress of each part of the metal ring cannot be guaranteed during the embossing process; The amount of feeding is consistent, so that the depth of the anti-skid groove cannot be guaranteed, which reduces the forming quality of the anti-skid groove; during the process of forming the anti-skid groove on the surface of the metal ring to the brick cement prefabricated part, the extruded raw materials will accumulate on both sides of the anti-skid groove. (2) During the embossing process of the metal ring on the surface of the brick cement prefabricated part, the surface of the brick cement prefabricated part will be subjected to a large extrusion force, and the extrusion force will be transmitted to its interior and side walls, eventually leading to cracks in the side walls or interior of brick cement prefabricated parts
