Description

Technical Field

[0001] The invention relates to the technical field of steel shot, in particular to a portable steel shot testing machine. Background Art

[0002] Steel shot is a spherical particle made of special materials through special heat treatment. Steel shot is widely used for descaling and rust removal of steel workpieces before painting. Centrifugal shot blasting equipment is often used in this case. The spherical shape and low hardness of steel shot will not cause significant wear to the equipment.

[0003] Shot blasting machine refers to a casting equipment that uses high-speed projectiles thrown by a shot blaster to clean or strengthen the surface of castings. The shot blasting machine can simultaneously remove sand, core and clean the castings. In some areas, it is also called sandblasting machine or sandblasting machine.

[0004] After the steel shot is produced, it needs to be tested for performance. The traditional testing method is to put it into use in the equipment in time, and then record the time and number of times it is used when problems occur in the steel shot to determine the service life of the steel shot. This method is time-consuming and easy to cause damage to the equipment. Most of the common testing equipment on the market are large in size, high in cost, and high in operating cost, which invisibly increases the burden on the company. If the steel shot that has not been tested and measured for performance is sold as a commodity, or is put into normal use in the equipment, it will cause unnecessary losses.

[0005] Therefore, designing a testing machine that is small in size, low in cost, convenient in testing, and can perform tests independently of the equipment is exactly the problem that the inventor wants to solve. Summary of the invention
