Magnet seal -- a new technology of shot blasting seal

Writer: admin Time:2022-10-18 08:30:02 Browse:183℃

In the process of development of shot blasting cleaning machine, how to solve the shot blasting machine in the process of blasting tiny splash problem, is notoriously difficult, because of high projectile ejection in blasting, mostly velocity between 75-90 m/S, blow to the workpiece surface and the speed can be reduced after multiple reflection between 15 to 30 m/S, so the crackdown and range is very wide, How to solve the sealing problem of hook type shot blasting machine to prevent projectile splashing has become a difficult problem for many manufacturers and design engineers. Qingdao Friendly Casting Machine Co., Ltd. uses magnets as an important option in part of the equipment seal. Unexpected effects occur during the use of the equipment.

Magnet seal is mainly used for: bed continuous pass type shot blasting machine, claw manipulator type shot blasting machine, hook type shot blasting machine, road shot blasting machine, etc

One, the magnet application in the bed type shot blasting machine摆床03.jpg

With the casting industry in the national requirements of transformation and upgrading, the elimination of backward production capacity, the upgrading of casting line resulting in a good application prospect of bed type shot blasting machine. A lot of problems have been exposed in the use of the swing bed shot blasting machine. Among them, the supporting wheel chamber of the swing bed enters the steel shot, resulting in the inclusion of projectile between the supporting wheel and the guide rail of the swing bed, affecting the service life. Our company uses N52 Ndfeb magnet strong magnet permanent magnet ring on the opposite magnetic pole of the driving roller of the bed body to seal, so that a certain thickness of projectile ring layer is formed between the permanent magnet ring and the sealing plate of the cleaning room, so as to block the channel into the steel ball. The magnetic pole is opposite, the magnetic force offset can effectively solve the problem of the force of the swing bed wheel, and the problem of the inclusion of pellets has achieved good results.

Two, claw manipulator type shot blasting machine magnet application

Claw manipulator type shot blasting machine can carry on the specific Angle and the specific position of the workpiece surface fixed point clearing way, by the production enterprise more and more favor. Due to the requirements of production capacity, most of the two stations or multiple stations in production; The spatter of steel shot will be caused in the working process of the rotary chamber. In our production practice, we install N52 Ndfeb magnet strong magnet strip at the edge of the rotating chamber, so that the stroke between it and the outer chamber is stable. The rear projectile cannot penetrate the flow curtain layer so that it will not splash and escape.

Three, hook type shot blasting machine magnet application

Hook type shot blasting machine is one of the most widely used types in the industry with the largest output. The splash of the projectile in and out of the middle electric hoist channel and the rotating part of the hook is the most feedback problem using the manufacturer. My company in the market research and their own production process, constantly explore the use of various forms and structures. Finally, the combination of flip plate + half moon type magnetic ring sleeve seal is adopted to completely remove the chronic disease in the industry. Half moon magnet ring sleeve is installed in the flip plate hook rotation part, when the hook into the type, the magnet ring sleeve and the formation of a strong magnetic field space, into the steel shot will be absorbed and captured on the magnet ring accumulation. Avoid the phenomenon of escaping and scattering to the surrounding.

Four, the application of magnet in the road shot blasting machine

Road shot blasting machine is high-speed rail, road and bridge industry in the largest output, the most widely used. Shot blasting machine and ground contact part of the projectile splash is the use of the manufacturer's feedback most of the problem. My company in the market research and their own production process, constantly explore the use of various forms and structures. Finally, the edge position of the sealed rubber sheet + is equipped with N52 Ndfeb magnet strong magnet strip, so that the stroke between it and the ground is stable. The rear projectile cannot penetrate the flow curtain layer so that it will not splash and escape.

Q341 turret shot blasting machine is one of the most widely used types with the largest output in the industry. Shot blasting machine rotation part and the chamber body contact parts of the projectile splash is the use of the manufacturer's feedback most of the problem. My company in the market research and their own production process, constantly explore the use of various forms and structures. Finally, the edge position of the sealed rubber sheet + is equipped with N52 Ndfeb magnet strong magnet strip, so that the stroke between it and the ground is stable. The rear projectile cannot penetrate the flow curtain layer so that it will not splash and escape.
