Strengthening principle of shot peening machine
  The shot blasting machine is evolved from the sand blasting machine, which combines all the advantages of the sand blasting machine
It is developed by the R & D team of Kunshan meifrey mechanical equipment Co
, Ltd
combined with advanced technology at home and abroad
The process of shot peening strengthening is that the high-speed projectile flow continuously sprays onto the surface of parts
The ejection of projectile flow is like countless small hammers hitting the metal surface
This makes the metal surface layer produce extremely strong plastic deformation, that is, produce cold work hardening layer, which is called surface strengthening layer
From the stress state, high residual stress is formed in the strengthened layer; From the perspective of microstructure, dislocations with extremely high density (> 1012  1 / cm2) are formed in the strengthening layer, and under the action of subsequent alternating stress or temperature (or both), the dislocations are gradually arranged regularly, forming polygonization, so that smaller sub grains (substructures) are gradually formed in the strengthening layer The compressive stress state and microstructure in the shot peened strengthening layer, which are different from the core (matrix), are two main factors to improve the fatigue strength at room and high temperature and the stress corrosion resistance of parts
The compressive stress and microstructure in the strengthening layer are not fixed
Generally speaking, the residual stress of the parts will gradually relax, and the subgrain will gradually grow, or even recrystallize, in the process of long-term bearing alternating stress at room temperature or high temperature
In general, the disappearance rate of residual stress and the growth rate of subgrain depend on the level of applied alternating stress and temperature
The higher the stress and temperature, the greater the change rate of the above two
Therefore, after a period of use, shot peened parts often need to be shot peened again in order to restore the effect of shot peened strengthening,  
  The form of shot blasting machine is mainly divided into two types: pneumatic shot blasting machine and mechanical centrifugal shot blasting machine

Main structure of shot peening machine
  A complete shot peening machine is generally composed of six systems, namely, structural system, medium power system, pipeline system, dust removal system, control system and auxiliary system

Function of shot peening machine
Workpiece surface strengthening, direct adhesion between workpiece and coating, workpiece surface cleaning, etc

Characteristics of shot peening machine
  Unlike other sand blasting equipment, shot peening machine is a kind of strengthening treatment equipment that enables the projectile to accelerate the ejection and obtain enough kinetic energy to hammer the metal surface
According to the characteristics of the shot peening machine, the shot peening machine is suitable for cleaning the rough surface of forged castings, stamping parts and machined parts, for the pretreatment process before spraying and electroplating, and strengthening the surface of polished parts
The shot peening machine is especially suitable for single piece and small batch production of medium and small parts
The shot peening machine is characterized by air inlet pressure, shot peening pressure display, and pressure reducing valve, which can adjust the shot peening pressure as required
A filter is installed at the compressed air inlet to filter the moisture in the compressed air?? The shot peening machine is equipped with automatic separation and automatic dust removal system
The used shot material is conveyed from the bottom of the machine to the cyclone separator for separation by negative pressure, so as to separate the dust, rust, oxide skin and other impurities produced in the process of shot peening from the good steel shot material
The characteristics of the shot peening machine enable the sand materials that continue to be used by the shot peening machine to be stored in the hopper at the lower part of the separator and recycled
Impurities such as large oxide skin are blocked by the screen at the lower part of the separator
The dust part is transported to the dust box of the shot peening machine for treatment
The dust is collected and the clean air is discharged into the atmosphere

Purpose of shot peening machine
?? Shot peening equipment has been widely used in machinery manufacturing industry, automobile manufacturing industry, heat treatment industry, shipbuilding industry, aviation industry, railway industry, thermal power / wind power industry, mold industry, steel industry, hardware industry, motorcycle parts industry, bearing industry, valve industry, machine repair and many other fields
As a conventional strengthening treatment equipment, shot blasting equipment has a unique processing mechanism and a wide range of processing and application after continuous development, improvement and improvement
Shot blasting equipment is more and more favored by customers in today's surface treatment and surface strengthening industry
