Preparation method of NiFeBMo-based opening and closing locker multilayer composite structure material

Abstract

The invention discloses a preparation method of a NiFeBMo-based opening and closing locker multilayer composite structure material. The NiFeBMo-based opening and closing locker multilayer composite structure material is prepared from NiFeBMo matrix alloy, an anti-wear agent, a heat conduction agent, a reinforcing agent and a curing agent as raw materials through the steps of structural design andcomponent calculation of all layers, matching preparation, vibration mixing, dry hot-press molding, curing heat treatment, overlaying sintering and machining of all layers. The NiFeBMo-based opening and closing locker multilayer composite structure material has the advantages that all layers are different in component and thickness, and the component difference is large; the material shows the gradient distribution trend, the relative use amount of the material is reduced, and the friction and wear performance of the material is remarkably enhanced. Meanwhile, the preparation method is simple,the preparation technology is easy to control, efficiency is high, technological parameters are stable, operation is easy to control, all layers of structures of a prepared opening and closing lockercan be freely divided and repaired, the mechanical performance is stable, and the service life is long.

Description

technical field [0001] The invention belongs to the technical field of material synthesis for mechanical parts, and in particular relates to a method for preparing a NiFeBMo-based multi-layer composite structure material for an opening and closing locker. Background technique [0002] The opening and closing locker device commonly used in mechanical structural equipment is a locking mechanism that is mainly composed of a machine base, a support frame and a rotating frame and can realize quick opening and closing operations. It is mainly used for disassembling, locking and fixing mechanical parts and equipment debugging, and can maintain a balanced pressure in the long-term opening and closing process (Jiangsu Huaguang Shuangshun Machinery Manufacturing Co., Ltd., an opening and closing locker device, CN0820645579.0; Langfu Fastening Technology Co., Ltd., An opening and closing locking device, CN0321869421.3). However, the locking device usually bears relatively large pressu...

Problems solved by technology

However, the locking device usually bears a large pressure during the working process. During the long-term opening and closing process, the opening and closing locking device is prone to friction and wear, which reduces the locking pressure and loses the pressure balance.

At the same time, during the opening and closing process, the friction will generate high surface temperature, which will easily cause surface friction cracking of the opening and closing locker, reduce the use efficiency, and shorten the service life (Quan Bing, reliability analysis of packer locking device based on finite element method, Neijiang Science and Technology, Issue 3, 2018)
