What are the advantages of automatic sandblasting machine

2019-06-06

Automatic sandblasting machine is a kind of sandblasting machine which uses compressed air as power to work. It can work automatically without manual operation except for the up and down of workpiece. Let's talk about the advantages of automatic sandblasting machine. 1. The metal parts of the full-automatic sandblasting machine are basically not damaged and the dimensional accuracy will not be changed; 2. The surface of the parts will not be polluted and the spraying materials will not react with the materials of the parts; 3. The full-automatic sandblasting machine can easily handle the groove, concave and other parts that are difficult to contact, and the spraying materials of various sizes can be selected for use; 4. The processing cost is greatly reduced, which is mainly reflected in the sandblasting equipment The improvement of work efficiency can meet all kinds of surface finishing requirements; 5. Low energy consumption and cost saving; simple operation and cost saving.

Operation principle and type of automatic sandblasting machine

The automatic sandblasting machine uses the compressed air as the power to spray the abrasives to the surface of the workpiece to be processed through the high-speed movement of air flow to form a negative pressure in the spray gun. The roughness or shape of the surface of the workpiece embedded or impacted by the abrasives from Shanghai sandblasting machine manufacturer changes, the mechanical properties of the surface of the workpiece are improved, and the hardness of the surface of the workpiece is slightly improved Degree of appearance. Features of the automatic sandblasting machine: 1. The triangular belt is used to transport the workpiece without sand accumulation, and the belt speed can be adjusted by frequency conversion according to the sandblasting process requirements; 2. The viewpoint of each spray gun can be adjusted freely to complete the automatic frequency conversion shaking and fixed-point sandblasting, with strong flexibility; 3. The advanced upper cyclone separation system configuration is selected, with good dust separation effect and high sandblasting efficiency; 4. The PLC electrical advanced system is selected The control system has high degree of automation, good stability and low failure rate; 5. The nozzle uses special high wear-resistant boron carbide data, with long service life; 6. The independent bag type dust removal system, with outstanding dust extraction and ventilation effect; 7. The abrasive wave uses the combination of spiral transportation and power recovery, with stable recovery. It is suitable for sand blasting of flat plate, plate, square body, profile and other special-shaped workpieces, such as flat stainless steel plate, parallel steel plate, glass steel plate, stone material, non stick pot, baking pan, toaster, computer case, function DVD panel, notebook, computer main board, electric iron base plate, decorative parts, sign badge, communication equipment, aluminum plate, profile and other special-shaped parts And so on.


Disadvantages of dry sand blasting

Sand blasting is a key process in the process of die machining, which is driven by compressed air to form a high-speed jet of abrasive solid particles through the spray gun and spray them to the surface of the workpiece at high speed. It changes the surface cleanliness, roughness, mechanical properties and technological characteristics of the workpiece through abrasive impact and cutting. At present, dry sand blasting is widely used for pretreatment, but there are many shortcomings of dry sand blasting: serious dust pollution, harm to human health, easy to attach dust on the surface of workpiece, unable to be directly arranged in the production line, separate and independent sand blasting device increases the production efficiency of the rotating link. In order to solve the above problems, a wet sand blasting device is designed, which can significantly improve the surface roughness and stress distribution of the workpiece, effectively eliminate the dust pollution of dry sand blasting, and can be directly installed in the production line, improve the production efficiency, convenient operation and application economy, which is conducive to the process upgrading and technological innovation of the enterprise, and has high application and promotion value.
