Moment-of-force type metal band precision polisher

Abstract

The invention relates to a polisher which is especially designed for using Dupont brush heads. The polisher is characterized in that a moment-of-force type polishing mode is adopted. The polisher is composed of one or more pairs of rotary polishing wheel brushes. Each pair of rotary polishing wheel brushes is composed of the upper surface polishing wheel brush and the lower surface polishing wheel brush, wherein the rotating speed of the upper surface polishing wheel brush and the rotating speed of the lower surface polishing wheel brush are the same, and the upper surface polishing wheel brush and the lower surface polishing wheel brush rotate in the same direction. The number of the selected polishing wheel brush pairs depends on metal materials and the surface oxidation characteristics of the materials. Each polishing wheel brush head is made of Dupont wires and has the advantages of being good in abrasion resistance, good in toughness, small in grinding angle and capable of achieving precision polishing. The self-stability of the polishing wheel brushes is good, the acting force direction of the upper surface polishing wheel brush and the acting force direction of the lower surface polishing wheel brush in each pair of polishing wheel brushes are opposite on a metal band, and no extra traction force or resistance is caused after compensation. When polishing wheels rotate, the brush heads and workpieces make full contact through the resultant moment of force of elastic force, gravity and rotary force, the rotating speeds of the polishing brushes can be adjusted according to polishing work conditions and workpiece materials so as to acquire different moments of force, and on-line continuous precision polishing under automation control can be achieved by grasping the corresponding relations between the rotating speeds and the movements of force.

Description

Technical field: [0001] The invention belongs to the field of metal material preparation and processing, in particular to a torque-type metal belt precision grinding machine. Background technique: [0002] Traditional methods for cleaning the oxide layer on the surface of metal strips include chemical methods, shot blasting methods, mold methods, manual grinding methods, and continuous grinding methods. For iron and steel metal strips, the surface oxide layer is not dense, and the oxide layer is easy to react with acid, and chemical methods can be used; for titanium and aluminum metal strips, the surface oxide layer is thick and dense, and the oxide layer is difficult to react with acid and alkali. For the reaction, multi-pass chemical method or shot blasting plus chemical method can be used; for metal copper strip, the oxide layer is thin and dense, and mold method or grinding method can be used. [0003] The chemical method is strictly restricted by environmental protecti...
