The Assembling Process of the Shot Blasting Machine

The Assembling Process of the Shot Blasting Machine


What is shot blasting equipment?
Generally speaking, shot blasting equipment for workpieces includes shot blasting equipment for of sand removal and finishing such as cutting, repair welding, and relief grinding.

The tumble shot blasting machines, the hook type shot blasting machine, the drum type shot blasting machine, etc., all belong to the shot blasting equipment.

Sand removal of castings mainly is to use the shot blasting machine to remove the oxide skin on surfaces of castings after heat treating so as to meet quality requirements of the castings' surfaces and cavities.

The assembling process of the shot blasting machine
1. Preparations before assembling the shot blasting machine
Firstly, assemblers should study the following details or make clear the following questions carefully before assembling the shot blasting machine. Study the general assembling drawings, process files, technical materials, the structure of the shot blasting machine, the workpieces to be cleaned by the shot blasting machine, the number of the blast wheel, the size of the dust collector, the materials and sizes of the backplate, the functions of the shot blasting machine's parts, the connection methods and relationships among different parts.

Prepare all the detailed drawings of the shot blasting machine's parts. Get all the needed parts from the warehouse according to drawings, and prepare all the needed tools. 

Conduct quality tests for parts that will be assembled, and scraping is needed for parts with special requirements. 

2. The assembling work of the shot blasting machine
The assembling work of the shot blasting machine should be done step by step, and the complex and separate parts such as the blast wheel, the dust collector, the chamber of the shot blasting machine, the elevator of the shot blasting machine, etc. can be assembled firstly. Assemble all the assembled parts into a whole shot blasting machine at last. 

3. Adjustments, inspections and test running of the shot blasting machine
The adjustment of the shot blasting machine: adjust mutual positions of parts, the fit clearance and the tightness degree of junctions so as to make all the parts coordinate with the shot blasting machine

Inspection of the shot blasting machine: inspect the geometric accuracy and the working accuracy of the shot blasting machine, for example, inspecting the liner clearance. Whether each parts of the shot blasting machine are assembled according to drawings should also be inspected.

Test running of the shot blasting machine: test the flexibility, the vibration state, the dust removal effect, the sealing effect, the cleaning efficiency, whether liner plates are welded firmly, and whether all parts of the shot blasting machine are assembled compactly and reasonably, etc.
