Treatment measures for sandblasting defects of bottle-like workpieces in mobile sandblasting machines

Mobile sandblasting machineWhen sandblasting the inner wall of the workpiece in the bottle, quality problems such as partial drop-shaped pits and irregular protrusions often appear inside the bottle cavity. These problems are not only problems of quality defects. This is mainly due to the following two reasons: one is the uneven sandblasting and other quality defects on the inner wall of the bottle workpiece due to the small mouth of the bottle workpiece; the second is the problem of the structural limitation of the sandblasting box of the mobile sandblasting machine. After research and analysis, Baiyao Automation Company found that in order to solve the two problems appealed, it is necessary to start with the cutting volume of the mobile sandblasting machine. The specific implementation plan is as follows:

One is to improve the nozzle structure. The front end of the nozzle of the mobile sandblasting machine is turned into a closed structure, and then multiple holes are punched in different directions of the pipe wall. When sandblasting bottle-like workpieces, sand particles will be sprayed from the pipe holes in different directions to reduce the amount of cutting; in addition, because the new nozzle of the mobile sandblasting machine is not open directly in front, and there is a gap with the pipe wall hole. A certain distance, after this improvement, can solve the problem of too close to the workpiece during sandblasting, so as to avoid the phenomenon of excessive cutting in the cavity of the bottle workpiece.

The second is to reduce the operator's work intensity. In order to reduce the operating intensity of the operator and enable the operator to flexibly control the bottle workpiece, the mobile sandblasting machine manufacturer has designed a special rotating bracket for the bottle workpiece, so that the parts can rotate freely on the bracket, which greatly reduces The work intensity of the operator. At the same time, the operator can use this bracket to better control the bottle-like workpieces, thereby effectively reducing the problem of the nozzle of the mobile sandblasting machine being too long in one area.

The third is to choose a suitable blasting medium. The mobile sandblasting machine needs to choose a suitable sandblasting medium to reduce the cutting amount of sandblasting. The sandblasting media currently used in the market mainly include white corundum, brown corundum, and quartz sand. Through practical experiments, it is found that although the cutting volume of quartz sand is smaller, the efficiency is too low, while the cutting volume of white corundum is larger. , But it can be improved by other technological means. The important thing is that white corundum, as the sandblasting medium of the mobile sandblasting machine, can greatly improve its sandblasting efficiency and save a lot of sandblasting time.
