Problems solved by technology

The binder and glass powder are easy to form bubbles formed by carbon dioxide, water vapor, etc. released at high temperature, making it impossible to form a continuous, uniform, and dense lubricating layer on the surface of the forging, so it cannot exert the proper lubricating effect and affect the forging. The surface quality of the product has relatively high requirements for the adhesive

Embodiment 1

[0038] Get a piece of glass fiber cloth 3500x1000x2mm; adopt clear water to configure graphite mass concentration as 10L of graphite lubricant solution of 16%, the prepared graphite lubricant solution is evenly sprayed on the front of the glass fiber cloth with a spray gun, and naturally air-dried to obtain lubricating and The graphite-coated side of the forging cloth for thermal insulation is as follows: image 3 As shown in A, the other side not coated with graphite is as image 3 Shown in B.

[0039] from image 3 It can be seen that the graphite layer is uniformly attached to one surface of the glass fiber cloth. The thickness of the graphite layer is 0.8 mm.

[0040] The prepared forging cloth with lubricating and thermal insulation functions according to figure 2 The structure shown is installed for forging aircraft flanges, a large projected surface forging with high rib and thin web structure, the pressure during forging is 780MN, and the underpressure is 5mm (loa...

Abstract

The invention relates to a forging fabric, in particular to a forging fabric having heat preservation and lubricating effects, and belongs to the technical field of forging and pressing. The forging fabric having the lubricating and heat preservation effects is composed of a fiber layer and a graphite layer which is uniformly attached to any plane of the fiber layer. According to the forging fabric, starting from a key control point for reducing deformation resistance during forging, the fabric having lubricating and heat preservation functions at the same time is designed. The fabric takes afiber cloth as a heat insulating material, the influence of hard particles after the compression of heat insulating cotton is eliminated, at the same time the concentration of a graphite lubricant isimproved to 13% to 18%, and graphite can be uniformly attached to the fiber. A method for application of the forging fabric having the heat preservation and lubricating effects comprises causing one side of the forging fabric with the graphite lubricant to be in contact with a die to reduce friction, and causing the other side of the forging fabric to be in contact with a forge piece to prevent temperature loss.

Description

technical field [0001] The invention relates to a forging cloth, in particular to a forging cloth with thermal insulation and lubricating functions, and belongs to the technical field of forging. Background technique [0002] During the forging process, the forging needs to overcome the flow stress of the material itself to deform, fill the cavity, and obtain the desired shape of the product. In order to reduce the pressure during molding, lubricants are required, and the use of lubricants can also effectively improve the life of the mold. [0003] In addition, heat preservation is required during the forging process. Insulation cotton is usually used for heat preservation. The traditional heat preservation measure is to simply use heat preservation cotton. Hard particles, this kind of particles not only have no lubricating effect, but increase the friction and make the molding pressure rise sharply. [0004] The existing method of using a lubricant to reduce the pressure ...
