Kunshan shot blasting machine is a device that uses the component of shot blaster to throw the shot at high speed, so as to achieve the purpose of cleaning or strengthening its surface. Generally speaking, this kind of equipment can be used for core removal, cleaning and sand dropping at the same time. In many places, this equipment is called sandblasting machine or sanding machine. Now, Kunshan huaguanshen sandblasting machine will explain it What are the main functions and application fields of shot blasting machine.
1、 Main functions
It can remove the oxide scale or sticky sand on the surface of cast steel and cast iron to clean the surface of the casting, and it is also a necessary step for the quality inspection of castings. The casing of large steam turbine should be shot blasted before flaw detection, so as to ensure reliable results. The hook type shot blasting machine is divided into single hook and double hook. The hook type shot blasting machine loads workpieces alternately into shot blasting cleaning room by two hooks. The shot blaster is used to throw 0.2 ~ 0.8 projectiles to the surface of the workpiece, which makes the surface of the workpiece reach a certain roughness, makes the workpiece beautiful, or changes the compressive stress of the workpiece, and improves the service life. For castings, shot blasting is a necessary process to find the surface defects such as peeling and subcutaneous blowholes. The quality of castings can be guaranteed by shot blasting.
In the modern theory of metal strength, as long as the density of metal internal dislocation is increased, the strength of metal can be improved, and the use of shot blasting machine to blast metal can enhance its dislocation structure, which can help to improve the strength of metal. This method is very effective for those hardening metals that can not use phase transformation.
Shot blasting can form a compressive stress on the surface of the casting, which can enhance the tensile strength, corrosion resistance and fatigue strength of the casting. It can also correct the twisted thin-walled castings. It can replace the ordinary cold and hot forming process to process large thin-walled castings, avoid the residual tensile stress and obtain beneficial compressive stress.
2、 Field of application
1. It can be used in the manufacture of bearings. Generally speaking, the surface of bearings is required to be smooth, and the burr and impurities can be removed by shot blasting. Shot blasting machine is different from shot peening machine in that it is used to reduce the fatigue life of parts, increase different surface stress, increase the strength of components, or prevent fretting. According to the theory of modern metal strength, increasing the dislocation density of metal is the main direction of improving metal strength. Practice has proved that shot blasting is an effective method to increase dislocation structure of metal.
2. It can be used in shipbuilding. Most of the steel plates used in shipbuilding have rust, so shot blasting can be used to remove rust.
3. It can be used in automobile manufacturing. Many steel plates and castings used in automobiles require polishing, but they also need to be able to maintain the original shape and strength of the plates. Shot blasting can be used to polish without physical damage. The diaphragm, or parts that may affect the appearance of the parts, can be removed by shot blasting. The shot blasting machine can also remove the pollutants on the surface of a partial coating, and provide a surface profile to increase the adhesion of the coating, so as to strengthen the workpiece.
4. It can be used in the manufacture of hardware products. It can meet the requirements of smoothness, smoothness and cleanness of hardware by shot blasting.
5. Can be used in the field of electroplating, electroplating requirements and hardware requirements are similar, of course, can also be used for processing.
6. It can be used in the field of motorcycle accessories manufacturing, usually using roller type equipment to complete shot blasting operation.
In addition to the above, the shot blasting machine can also be used in the field of steel plate manufacturing to deal with the burr and other problems of newly discharged steel plate, and also can be used in the field of valve manufacturing to grind and polish the castings of valves, so as to meet the requirements of product quality.
