Because metal aluminum and aluminum alloys have good mobility and plasticity, and the forging process is forged in a pressure die-casting machine, the aluminum castings can make a variety of more complex shapes, and can also make higher accuracy and Finish, thus greatly reducing the machining amount of castings and the forging allowance of metal aluminum or aluminum alloy, which not only saves electricity, metal materials, but also greatly saves labor costs; and aluminum and aluminum alloys have excellent thermal conductivity , Small specific gravity and high processability. Because it adopts dry blasting and is equipped with a dust removal system, it can be transferred to the next process after blasting and cleaning, eliminating the equipment cost required for scouring and drying after liquid blasting.
After the shot blasting process, the attachments, thin edges, fins, and stains on the surface of the workpiece can be removed, and scratches can be eliminated to make the workpiece appear as the base. After shot blasting, the roughness can reach Ra1.6 ～ 6.3μm, the surface copper elbow area is greatly increased, and the surface dirt is eliminated at the same time. Therefore, when the surface is sprayed with https://www.bronzecast.net/product/air-conditioner-parts-series/elbow/ paint or other coatings, its adhesion is greatly enhanced. After blast cleaning, the surface structure can be improved, the surface stress (tensile stress) can be eliminated, the fatigue strength can be improved, and the surface hardness can be slightly improved.
Shot blasting yields high yield. During the part cooling process, due to uneven wall thickness and inconsistent cooling rate, stress concentration occurs on the surface.It is forbidden to put your hand into the aluminum mold (die) or take materials from it with bare hands.
StartingCheck the emergency stop button should be normal, check the total pressure of the hydraulic system, and the settings of various functional parameters should meet the work requirements.During machine maintenanceThird, other needsThe recycled materials of alloy ingots need to be specially treated to recognize that their chemical composition meets the requirements before they can be reused.After adding hydraulic oil or lubricating oil, wipe out the leaked oil as soon as possible. Because a new type of shot blasting machine is used to throw a projectile with a shooting speed of 50 to 75 m / s at a rate of 110 to 260 kg / min, the cleaning can be completed within minutes.
The process is simple and the investment is saved.Improve surface spray adhesion. Special attention: Do not use water, ordinary fire extinguishing powder, foam, CO2, N2 to extinguish fire.Don’t hit any part of the machine with tools. For magnesium alloy aluminum castings, special attention should be paid to no smoking and drinking water at the work site.
