Automatic grinding machine for metal plate

Abstract

The invention discloses an automatic grinding machine for a metal plate. The essentials of the technical scheme are that the automatic grinding machine comprises a rack, wherein a conveyor belt for placing a metal plate piece is arranged on the rack; on the rack, a grinding device for grinding the upper surface of the metal plate piece is arranged on the upper part of the metal plate piece; the grinding device comprises a grinding shaft perpendicular to the conveyor belt; a plurality of grinding brushes which can contact the metal plate piece are arranged on the peripheral surface of the grinding shaft in a manner of surrounding the circumference array of the grinding shaft; and a first driving piece for driving the grinding shaft to rotate is arranged on the rack. After the mounting is completed, the grinding shaft is driven by the first driving piece to rotate; because the grinding brushes are arranged in a manner of surrounding the circumference array of the grinding shaft, the grinding brushes rotate in a horizontal direction, so that the grinding brushes can contact the metal plate piece when burrs are removed; due to large contact area of the grinding brushes and the metal plate piece, the grinding efficiency also can be improved; meanwhile, the grinding brushes can be directly driven by a separate grinding shaft to rotate; and therefore, the structure is simple, and the production is very convenient.

Description

technical field [0001] The invention relates to a grinding equipment, more specifically, it relates to a sheet metal automatic grinding machine. Background technique [0002] At present, strip or plate metal workpieces are usually processed by laser cutting or punching, and burrs are often formed on the cutting edge, which must be removed before the workpiece is painted or finished; the traditional deburring process Generally, the burrs are removed by manual brushing. This method often relies on manual use of toothbrushes to rub repeatedly on the surface of the workpiece. This will cause some burrs to be removed effectively, and the work efficiency is low and labor costs are wasted. [0003] Therefore, the utility model whose notification number is CN103624647B provides a kind of deburring machine for sheet metal or machined metal workpieces. Small, while the workpiece conveyor belt does not contact the grinding brush, there is no wear between the workpiece conveyor belt an...

AI Technical Summary

Problems solved by technology

[0004] However, in actual use, the deburring machine in the prior art has a complex structure and a cumbersome working process; and, in use, only a single grinding brush contacts the sheet metal, and the contact area between the grinding brush and the sheet metal is small , low grinding efficiency
