Bent pipe sanding machine

Abstract

The invention provides a bent pipe sanding machine which comprises a machine frame, a motor fixing frame, a motor, a retainer plate fixing seat, a retainer plate, a sanding wheel, a dust collection pipe, a control box, a disc, a dustproof disc, a fixed gear, a gear fixing disc, a bearing, an outer snap spring, a snap spring check ring, abrasive belt power wheels, a driven gear shaft, abrasive belt distance deviation preventing wheels, an abrasive belt gap adjusting component, abrasive belt tightness deviation preventing wheels, an abrasive belt tightness adjusting component and abrasive belts. The abrasive belt gap adjusting component can adjust the gap between the two abrasive belts so that the abrasive belts can be used for sanding and polishing bent pipes of different sizes. V-shaped grooves are formed in the circumference of the curved surface of each abrasive belt deviation preventing wheel and achieve the functions of deviation prevention, sliding prevention and falling prevention for the abrasive belts. The problem that in traditional bent pipe polishing operation, a whole bent pipe can only be sanded and polished by continuously changing the polished face of the bent pipe is solved, the production cycle is shortened, work efficiency is greatly improved, labor cost is lowered, and the rate of finished products is high.

Description

technical field [0001] The invention relates to a bent pipe sand passing machine. Background technique [0002] The traditional polishing process for elbows is generally done by hand on one side. Manual operation has low work efficiency, poor polishing accuracy, poor processing effect, and high labor costs. Later, some semi-automatic polishing machinery and equipment appeared on the market, but whether it is traditional manual polishing or polishing of the elbow with polishing equipment, it is necessary to continuously change the polishing surface of the elbow to complete the polishing of the elbow. Polishing operation, this operation method of constantly changing the polished surface can easily cause uneven local polishing of the elbow, or inconsistent polishing degrees of each polished surface of the elbow, resulting in low yield and long processing cycle. Moreover, the polishing machinery and equipment in the current price range do not have the functions of anti-offset, ...

[0002] The traditional polishing process for elbows is generally done by hand on one side. Manual operation has low work efficiency, poor polishing accuracy, poor processing effect, and high labor costs.

Later, some semi-automatic polishing machinery and equipment appeared on the market, but whether it is traditional manual polishing or polishing of the elbow with polishing equipment, it is necessary to continuously change the polishing surface of the elbow to complete the polishing of the elbow. Polishing operation, this operation method of constantly changing the polished surface can easily cause uneven local polishing of the elbow, or inconsistent polishing degrees of each polished surface of the elbow, resulting in low yield and long processing cycle

Moreover, the polishing machinery and equipment in the current price range do not have the functions of anti-offset, anti-skid, and anti-falling, and the processing accuracy is poor.
