Automatic polishing and derusting system for two sides of U-shaped rib

Abstract

The invention discloses a U-rib double-side automatic polishing and derusting system which comprises a bottom machining base provided with a containing area and a derusting machining area, the containing area is divided into a feeding area and a discharging area, and the containing area of the bottom machining base is provided with a movable rack and a fixed rack; the movable rack and the fixed rack are each provided with a bottom rack base, a feeding stand column, a discharging stand column and a top cross beam frame, and the top cross beam frames are fixedly installed on the tops of the feeding stand columns and the tops of the discharging stand columns. A feeding placing seat corresponding to the feeding area and a discharging placing seat corresponding to the discharging area are further fixedly mounted on the bottom rack seat; the device further comprises a feeding mechanism, a discharging mechanism, a sand blasting and rust removing mechanism, a heavy hammer swing type carrier roller and a transferring and clamping mechanism. The device is high in automation degree, can automatically complete the whole process of feeding, sand blasting and rust removing operation and discharging of a single U-shaped rib, basically does not need manual intervention, well reduces the labor cost, improves the production efficiency, and is small in space occupation of the whole system equipment.

Description

technical field [0001] The invention relates to the technical field of U-shaped rib rust removal, in particular to a U-rib bilateral automatic grinding and rust removal system. Background technique [0002] At present, the method of removing rust on the to-be-welded position of the U-rib generally adopts the laser descaling method. The two ends of the device are arranged with conveying rollers for conveying U-ribs. The length of each conveying roller is basically the same as the length of the U-rib. Usually, the U-rib needs to be moved by the conveying rollers, so that the laser rust removal device can remove all the U-ribs. The welding parts are all polished and derusted. Using this processing method not only has low work efficiency, but also it is difficult to ensure that the primer and rust on each part of the U-rib can be polished and removed, and the edge burrs of the U-rib and the rust at the burr position cannot be removed. The operation effect is often unsatisfactor...

Problems solved by technology

[0002] At present, the method of derusting the position to be welded of the U-rib generally adopts the laser derusting method. During the derusting operation of the U-rib laser derusting device, the laser derusting device is installed at a fixed position. The two ends of the device are arranged to convey the U-ribbed conveying roller table. The length of each conveying roller table is basically the same as the length of the U-ribbed. Usually, the U-rib needs to be moved by the conveying roller table so that the laser derusting device can take all the U-ribbed parts. The welding parts have been polished and derusted. With this processing method, not only is the work efficiency low, it is difficult to ensure that the primer and floating rust on each part of the U rib can be removed by grinding, and it is impossible to remove the burr on the edge of the U rib and the rust on the burr position. The operation effect is often not ideal, and manual secondary operations are required; in addition, the length of the U-rib is generally long, and the maximum length can reach 20 meters. Using the above-mentioned method to process will occupy a large amount of operating space in the workshop, and it is impossible to realize automation. material, blanking
