A kind of preparation method of multi-layer composite structure material of nifebmo-based opening and closing locker

Abstract

The invention discloses a method for preparing a multilayer composite structure material of a NiFeBMo-based opening and closing locker. Using NiFeBMo matrix alloy, anti-wear agent, heat conduction agent, reinforcing agent and curing agent as raw materials, the raw material powder of each layer is passed through each layer Structural design and composition calculation, proportioning preparation, vibration mixing, dry hot pressing, curing heat treatment, superimposed sintering and each layer of machining process are made of NiFeBMo-based multilayer composite structure material for opening and closing locker, which has various The layer has the advantages of different composition, different thickness, and large component difference, and presents a gradient distribution trend, which not only saves the relative amount of materials, but also significantly enhances its friction and wear properties. At the same time, the preparation method of the present invention is simple, the preparation process is easy to control, the efficiency is high, the process parameters are stable, the operation is easy to control, and the structure of each layer of the obtained opening and closing locker can 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)
