Two-site polishing machine

Abstract

The two-site polishing machine includes frame, polishing plate and driving mechanism. The polishing plate is set on the frame and driven with the driving mechanism, and surface of the polishing plate includes outer layer of fibrous fabric. The polishing machine has two polishing plates, including one planar plate and one convex plate. The present invention makes it possible for the user to use the planar plate and the convex plate alternately in polishing plane, convex surface and concave surface of the product in high work efficiency.

Description

technical field [0001] The invention relates to metal product processing equipment, in particular to a metal product polishing machine. Background technique [0002] For a long time, the polishing of metal products, especially stainless steel products, has been polished by using flat discs or cam discs that are directly installed on the motor and made of hemp fiber or cloth. The specific operation method is: the motor is installed horizontally; the metal product is held in hand, the flat or convex surface of the product is polished with the cylindrical surface of the flat wheel, and the concave surface of the product is polished with the end surface of the cam disc; no polishing agent is added during polishing, which belongs to "dry" throw". There are currently three types of polishing machines, one is a flat disc polishing machine, the other is a cam disc polishing machine, and the other is a polishing machine with replaceable polishing discs. [0003] The above-mentioned...

AI Technical Summary

Problems solved by technology

[0004] 1. It is impossible to frequently and alternately use the flat disc and the cam disc to polish the flat, convex and concave surfaces of the product surface, and the work efficiency is low

[0005] 2. Since the polishing disc made of hemp fiber or cloth does not have enough elasticity, when it is in contact with the surface of the product, the contact surface between the two is very small

However, since the product is hand-held, it is impossible to avoid deviations, so the product will inevitably have under-polishing or missed polishing, and it needs to be re-polished afterwards, which will affect the polishing quality and work efficiency.

At the same time, the contact trace range between the polishing disc without sufficient elasticity and the surface of the product is very narrow, so even if there is no back-polishing, the polishing efficiency is not high

[0006] 3. The hemp fiber or cloth is relatively hard and not soft enough. The polishing wheel made of this kind of material will directly contact the surface of the product for polishing without adding any polishing agent, which will inevitably leave quite obvious lines on the surface of the product. Therefore, the brightness of the polished surface is poor, and the polishing effect is not good

[0007] 4. "Dry throwing" will also produce a lot of noise, serious dust pollution, and poor polishing working environment

[0008] In addition, although chemical polishing can polish the inner and outer surfaces of metal products at the same time, strong acids such as nitric acid and hydrochloric acid must be used in the chemical polishing solution.

The strong acids used are volatile, which not only pollutes the air and affects the health of on-site operators, but also the composition of the chemical liquid is easy to change, which affects the quality of polishing. Therefore, the chemical liquid needs to be accurately measured and adjusted frequently; more environmental pollution
