KNNJOO Hanging Chain Shot Blasting Equipment for Brakes Cleaning
Hanging Chain Shot Blasting Equipment Description
Suitable for shot blasting of large quantities of small and medium workpieces. The workpiece can run continuously or step by step along with the hoisting chain, or adopt advanced accumulation and push catenary conveying work, so that the workpiece is in a stopped state in the loading and unloading and shot blasting areas to realize the fixed-point loading and unloading and the fixed-point shot blasting process. The hoisting weight is 50-2000kg, and the production efficiency is high, the operation is reliable, and the cleaning effect is especially good for the surface and inner cavity of the workpiece, such as the engine cylinder head, the motor shell, etc. It is an ideal choice for industries such as automobiles, tractors, diesel engines, motors, and valves. The catenary shot blasting machine can be divided into continuous type, stepping type and accumulation type according to its hanging chain movement mode. According to the chain arrangement, it can be divided into single stroke, double stroke and multi stroke.

Application
The catenary shot blasting machine is a double-stroke catenary continuous shot blasting equipment, which has static loading and unloading of workpieces, automatic and fast conveying and positioning, and rotating shot blasting of workpieces. The whole machine is controlled by conventional electrical appliances, and the conveying track of the workpiece is continuously variable. It is suitable for all-round shot blasting cleaning of large batches, cast steel, cast iron, and welded parts, and is used for various types of hanging workpieces. Through shot blasting, not only can the rust on the surface of the workpiece be removed, and the welding slag on the structure can be cleaned, but also the welding stress of the workpiece can be eliminated, the fatigue strength of the workpiece can be improved, and the paint film adhesion of the workpiece can be increased. The purpose of improving the surface and internal quality of the entire workpiece. It is widely used in metallurgy, petroleum, chemical, machinery and other industries.
Workpiece strengthening
According to modern metal strength theory, increasing the dislocation density inside the metal is the main direction to improve the strength of the metal. Practice has proved that shot blasting is an effective process method to increase the metal dislocation structure. This is of great significance to some metals that cannot be hardened by phase transformation (such as martensitic quenching, etc.) or require further strengthening on the basis of transformation hardening. Aviation, aerospace industry, automobiles, tractors and other parts require lighter weight, but the reliability requirements are getting higher and higher. An important process measure is to use shot blasting to improve the strength and fatigue strength of components.
