Production and manufacturing method and device for cement board formed by extrusion hole drawing and embossing

Abstract

The embodiment of the invention discloses a production and manufacturing method for a cement board formed by extrusion hole drawing and embossing. The production and manufacturing method comprises thefollowing steps: machining raw materials are weighed to be preliminarily mixed, the preliminarily-mixed raw materials are kneaded through a kneading machine, after kneading is completed, the raw materials are placed into a mixing mill to be subjected to mixing milling, the raw materials subjected to mixing milling are placed into an extrusion machine, and forming machining of the cement board iscompleted by the extrusion machine in hole-drawing and embossing modes. The production and manufacturing device for the cement board formed by extrusion hole drawing and embossing comprises a die headplaced on the extrusion machine and used for conducting forming machining on the raw materials, and a fixed sleeve penetrating through the die head; and the end, away from the extrusion machine, of the fixed sleeve is provided with a hole-drawing assembly used for conducting hole drawing on the cement board, and an embossing assembly corresponding to the hole-drawing assembly is further arrangedon the die head. Through the arranged hole-drawing assembly, a drawn hole can be supported by a fixing rod to emboss the surface of the cement board when embossing is conducted through the embossing assembly, collapse of the drawn hole can be avoided in the embossing process, and embossing is more convenient.

Description

technical field [0001] Embodiments of the present invention relate to the technical field of cement boards, in particular to a method and device for producing cement boards formed by extrusion and embossing. Background technique [0002] Cement board refers to the board made of cement as the basic material and adhesive, mineral fiber cement and other fibers as reinforcing materials, through pulping, molding, curing and other processes. Cement boards are used in various domestic power plants, Fireproof and flame retardant for cable engineering in chemical companies and other places where electricity costs are intensive Material. [0003] At present, the common production processes of cement boards are mainly the flow method, the copying method, the molding method and the extrusion method, etc. The flow method and the copying method are mainly used to produce flat plates. Although the molding method can press out various patterns, it cannot draw holes. , it can’t achieve the...
