Problems solved by technology

However, due to the poor affinity between graphite and glass fiber cloth, after repeated forging, the graphite on the glass fiber cloth is easy to fall off, resulting in uneven lubrication and poor surface finish of the mold after forging; in addition, the glass fiber cloth The maximum thickness of graphite can only be 1mm. If the amount of graphite is further increased, the graphite will easily fall off during forging, which will also affect the surface finish of the abrasive tool after forging.

preparation example Construction

[0036] The preparation method of composite fiber cloth comprises the following steps:

[0037] a. Take basalt fiber cloth and graphite powder; wherein, the amount of graphite powder is calculated according to the amount of 110-150 grams of graphite powder needed per square meter of basalt fiber cloth;

[0038] b. Mix the graphite powder taken in step a with water to obtain a graphite emulsion; wherein, the weight ratio of graphite powder to water is 1:15 to 1:20; if the concentration of graphite emulsion is too high, the adhesion will decrease, and graphite is not easy to be evenly coated Cover the surface of fiber cloth; if the concentration is too low, graphite is not easy to coat on the surface of fiber cloth, and the adhesion amount cannot meet the requirements.

[0039] c. The graphite emulsion prepared in step b is evenly attached to the surface of the basalt fiber cloth in step a, and dried to obtain a composite fiber cloth.

[0040] Wherein, the drying is any one of a...

Embodiment 1

[0048] Get basalt fiber cloth, the thickness of basalt fiber cloth is 0.34mm, and the size is based on 100% coverage of the mold cavity surface area; adopt clear water and graphite to prepare graphite emulsion, and the weight ratio of graphite powder to water is 1:15; the obtained The graphite emulsion is evenly attached to both sides of the basalt fiber cloth, so that the graphite powder attached to each square meter of the basalt fiber cloth has a weight of 150 grams; and then dried to obtain the graphite composite basalt fiber cloth.

Embodiment 2

[0061] Get basalt fiber cloth, the thickness of basalt fiber cloth is 0.34mm, and the size is based on 100% coverage of the mold cavity surface area; adopt clear water and graphite to prepare graphite emulsion, and the weight ratio of graphite powder to water is 1:15; the obtained The graphite emulsion is evenly attached to both sides of the basalt fiber cloth, so that the weight of the graphite powder attached to each square meter of the basalt fiber cloth is 130 grams; and then dried to obtain the graphite composite basalt fiber cloth.

Abstract

The invention relates to composite fiber fabric for large-pressing-machine forging and a production method and application of the composite fiber fabric and belongs to pressing machine large forge piece forming forging. The composite fiber fabric is composited by basalt fiber fabric and graphite powder, wherein the graphite powder evenly attaches to two surfaces of the basalt fiber fabric. The composite fiber fabric is small in friction coefficient, good in thermal insulation and lubricating effects, high in pressure resistance, good in softness, high in elongation at high temperature and thelike.

Description

technical field [0001] The invention relates to a composite fiber cloth for large press forging, a preparation method and application thereof, and belongs to the field of forming and forging of large forgings of a press. Background technique [0002] The world's largest 80,000-ton large-scale die forging hydraulic press was put into production in Erzhong, China in 2013. At present, the 80,000-ton large press has undertaken the supporting research and development tasks of large forgings for national key models such as "C919 Large Aircraft", "Dayun Aircraft", "Engine", and "Smoke Turbine". Most of the large forgings undertaken are hard-to-deform alloys with high deformation resistance, which are characterized by large forging dimensions and high quality requirements. The production of forgings directly faces two major problems: firstly, it is difficult to form forgings due to the large deformation resistance; secondly, the stress and strain borne by the die per unit area are ...
