Embodiment 1

[0079] A method for producing a composite material stirring wing, comprising the following steps:

[0080] (1) Wax pressing process, using a wax pressing machine to make a wax mold, repairing the flash and burrs of the wax mold, and then assembling the wax mold to the pouring system, and welding the wax mold and the pouring system to form a wax tree;

[0081] (2) In the shell making process, the surface of the wax tree is coated with a coating with silica sol as a binder. When the coating does not flow, the upper layer of sand is sprinkled, and dried and solidified; similarly, the second layer of coating is sprinkled with the upper layer of sand; Starting from the third layer, paint with water glass as the binder, and sprinkle the upper layer of sand, and dry for 3-5 hours after each layer of paint to obtain the coated mold shell;

[0082] (3) Dewaxing process, put the coated mold shell into hot water above 95°C, and melt the wax in it to form a cavity mold shell;

[0083] (4...

Embodiment 2

[0094] A method for producing a composite material stirring wing, comprising the following steps:

[0095] (1) In the process of wax pressing, the prepared wax paste is injected into the wax press machine, and the wax mold is prepared by using the mold; at the same time, the wax mold is prepared with the wax paste to prepare the wax mold of the pouring system. The wax mold is repaired with burrs, and then the wax mold is assembled on the pouring system, and the wax mold and the pouring system are welded to form a wax tree;

[0096] (2) In the shell making process, the surface of the wax tree is coated with a coating with silica sol as a binder. When the coating does not flow, the upper layer of sand is sprinkled, and dried and solidified; similarly, the second layer of coating is sprinkled with the upper layer of sand; From the third layer, paint with water glass as a binder, and sprinkle the upper layer of sand, and dry for 3 hours after each coat of paint to obtain a coated ...

Embodiment 3

[0109] A method for producing a composite material stirring wing, comprising the following steps:

[0110] (1) In the process of wax pressing, the prepared wax paste is injected into the wax press machine, and the wax mold is prepared by using the mold; at the same time, the wax mold is prepared with the wax paste to prepare the wax mold of the pouring system. The wax mold is repaired with burrs, and then the wax mold is assembled on the pouring system, and the wax mold and the pouring system are welded to form a wax tree;

[0111] (2) In the shell making process, the surface of the wax tree is coated with a coating with silica sol as a binder. When the coating does not flow, the upper layer of sand is sprinkled, and dried and solidified; similarly, the second layer of coating is sprinkled with the upper layer of sand; From the third layer, paint with water glass as a binder, and sprinkle the upper layer of sand, and dry for 4 hours after each layer of paint to obtain a coated...

Description

technical field [0001] The invention relates to the technical field of stirring wing materials, in particular to a production method of a composite material stirring wing. Background technique [0002] The stirring wings in the vehicle-mounted bottom mortar mixing and conveying mechanism bear the surface friction and impact fatigue caused by the alternating load of mortar during work. This working condition requires that the stirring wings must have the following functional indicators: (1) The surface hardness is high to adapt to the wear-resistant working environment; (2) The product structure is dense, and the core has appropriate toughness to adapt to the impact of alternating loads. This can overcome the impact fatigue fracture of the product caused by the material brittleness brought about by high hardness. [0003] The main parameters of the existing stirring wings are: unit weight 3.60Kgs / piece; main wall thickness 15mm; outline main dimension 300*200*130mm. The mai...
