噴砂設(shè)備可用作對(duì)金屬的銹蝕層、熱處理件表面的殘鹽和氧化層、軋制件表面的氧化層、鍛造件表面的氧化層、焊接件表面的氧化層、鑄件表面的型砂及氧化層、舊機(jī)件表面等進(jìn)行處理。噴砂設(shè)備還可以改變工件表面粗糙度,可以產(chǎn)生亞光或漫反射的工件表面,以達(dá)到光飾加工的目的。所以噴砂設(shè)備被廣泛應(yīng)用于鑄造機(jī)械行業(yè)中。
如何選擇噴砂設(shè)備?要從以下幾個(gè)方面考慮:
1.一般而言,噴砂設(shè)備的效果主要由零件材料及噴砂磨料決定。根據(jù)零件材料的不同,噴砂磨料范圍可從效果強(qiáng)烈的金屬磨料到效果柔和的樹(shù)脂磨料,同時(shí)干噴砂與液體噴砂亦是重點(diǎn)考慮的因素。
2.生產(chǎn)效率確定噴砂設(shè)備種類。根據(jù)加工能力選擇自動(dòng)化噴砂生產(chǎn)線、半自動(dòng)化噴砂設(shè)備、壓入式噴砂機(jī)、吸入式噴砂機(jī)。
3.工件尺寸確定噴砂設(shè)備規(guī)格。根據(jù)工件尺寸選擇機(jī)艙大小,以便有足夠的空間完成處理工作。
4.壓縮空氣要求。根據(jù)噴砂設(shè)備規(guī)格確定空壓機(jī)容量,并留20%余量,以保護(hù)空壓機(jī)使用壽命。

Sandblasting equipment available corrosion layer, heat treatment of surface residual salt and oxide layer, the oxide layer on the surface of the rolling, forging, welding pieces of the oxide layer on the surface of the oxide layer on the surface of the casting surface, sand and the oxide layer, the old mechanical surface treatment. Sandblasting equipment can also change the surface roughness of the workpiece, can produce matte or diffuse to the surface of a workpiece, so as to achieve the purpose of finishing processing. So the sandblasting equipment is widely used in foundry machinery industry.
How to choose the sandblasting equipment? Should from the following several aspects to consider:
1 in general, sandblasting equipment effect parts from the main materials and blasting abrasive decision. According to parts of different materials, abrasive blasting can range from the effects of the strong metal abrasive to the effect of soft resin abrasive, and dry sandblasting and liquid sandblasting is also focused on the factors considered.
2 determine the efficiency of production of sandblasting equipment types. According to choose automated sandblasting processing capacity production line, semi-automatic sandblasting equipment, pressure-in sand blasting machine, suction type blasting machine.
3 workpiece size determine sandblasting equipment specifications. According to the workpiece size choose the cabin size, so that there is enough space to complete processing.
4 compressed air requirement. According to the blasting equipment specifications to determine the air compressor capacity, and left20% margin, in order to protect the service life of the air compressor.
