Shot Peening Strengthening
Product Description
Shot peening technology
There are three types according to shot blasting application. 1. shot blasting cleaning 2. shot peening 3. shot peening forming shot peening is traditional surface treatment technology, the principle is : by means of impacting of high speed shots on the workpiece, to make it plastic deform in order to produce residue stress, and increase the bent/twist fatigue strength of parts, improve stress corrosion splitting performance. The shot peening is a process of cooling, that is numerous round shots beating on the surface, like a micro hammer beating on the surface to produce small indentation and hollow.
You can imagine, in a pressure stress area, split is hard to form or extend. As almost all the fatigue and stress corrosion occur on the surface or near the surface, thus by shot peening, the lifetime of spare parts can be extended. The residual stress by shot peening must reach half of the tensile strength of part material.
The notable enemy of metal fatigue failure is tensile stress. The production of tensile stress is due to alternate load by exterior or residual stress of production process like welding, grinding. Tensile stress tries to stretch or pull the surface to cause split in the final.

Digital control shot peening machine for automobile industry
The requirement of automobile is low cost, and can keep good performance in a high alternating load. By protecting the surface from damage caused by circulation loading when operating, the surface treatment can improve the performance of parts.
Digital control shot blasting application:
Fatigue- by virtue of implanting a certain amount of extrusion pressure can control effectively of the surface contact and extrusion stress on the surface of parts,
Abrasion- the abrasion will result in fatigue destroy, suitable shot blasting will improve the surface contact and produce extrusion pressure on the surface, thus reduce the abrasion.
Stress corrosion split- reduce the surface stress or reduce it below the limit point and remove the split corrosion by stress.
Shot peening machine for CNC gear
Shanghai Liangshi designs and manufactures for a famous automobile group corporation 3 sets of digital control gear shot peening machine; shot peening process is an important way to increase the gear bent fatigue resistance, to improve gear seizure resistance, extend the gear lifetime. Along with the development of application arrange, the capacity of improving gear fatigue resistance and lifetime has been proven by most enterprises.
Making use of high speed shot flow (strengthened shot blaster supply) impact on the metal surface to create plastic circulation strained layer, thus resulting in the dislocation in the micro structure, and sub-boundary and grain refinement. The reliability and durability is enhanced.
Ceramic shot and steel shot strengthening system equipment
Shanghai Liangshi Group designs and manufactures a set of shot blasting system, the shot blasting system is used in the surface shot blasting treatment of top metal material, and ceramic shot and steel shot blasting treatment.
The Tianjin United States company covers business of every field like aviation, automobile, power generation, petroleum, natural gas, medical and other industries. We can meet the market needs of top-grade metal surface treatment, and good at shot blasting, shot peening, lazer strengthening, professional coating, thermal treatment, chemical treatment.
Automobile Stamping Hot Rolled A column B column shot peening equipment
Shanghai Liangshi Group designs and manufactures automobile hot-formed A-column, B column suspended conveying full automatic shot peening line and coating rust and oil proof line for a Shanghai automobile system corporation. The bumping post, bumper reinforcing beam, car body A column, B column, door frame reinforcing beam is treated by shot blasting to remove rust and strengthened. The full set shot blasting line exceeds present international level and elevate the product competitiveness of the automobile system corporation in the industry.
In the circumstances of high capacity requirement, like automobile spare parts manufacturing industry, strengthened connecting rod, gear, flat spring, coil spring can select shot blasting technology.
Whether shot peening of that making use of compressed air, or making use of blast wheel blade, the process required monitoring of key process parameters and closed type feedback, including media flow and speed. The speed control of media speed is realized by adjusting blast wheel speed in the shot blaster, and adjusting pressure in shot peening equipment.
