Fast assembly press grinding plate for sander and manufacturing method thereof

Abstract

The invention discloses a fast assembly press grinding plate for a sander and a manufacturing method thereof, and relates to an abrasive belt press grinding plate of sanding machinery and the manufacturing method thereof. The press grinding plate is formed through bonding and compounding a substrate, a cushion and graphite cloth, wherein rabbets are formed in the two side edges of the substrate; the rabbets can be in fit and socket connection with rabbet grooves of a press grinding plate base; the substrate can be a wood fiber plate, wood-plastic plate, plastic plate, acrylic plate or composite plate; the cushion can be a wool felt pad, needle-punched nonwoven felt pad, artificial leather pad, resin foaming sheet or compressed sponge pad; and the graphite cloth is formed through coating the surface of canvas with a mixed coating of graphite and an adhesive. The manufacturing method comprises the sequential steps of manufacturing the substrate, the elastic cushion and the graphite cloth; bonding and compounding the elastic cushion with the substrate; and bonding and compounding the graphite cloth with the elastic cushion bonded with the substrate. The fast assembly press grinding plate has the beneficial effects that the substrate and the elastic cushion can be made from various different materials, the fast assembly press grinding plate can better meet the processing requirement of different processing parts, pull-insert type quick assembly can be achieved, changing and utilization are convenient, novel graphite cloth is adopted, the lubricating and abrasion performance is better, the fast assembly press grinding plate can be manufactured in batches by professional manufacturers, cost is low.

Description

[0001] Technical field: [0002] The invention relates to woodworking machinery, mainly to a sanding machine for sanding and planing wood products or other metal products, and in particular to a grinding plate for pressing and grinding abrasive belts matched with a sanding machine and a manufacturing method thereof. [0003] Background technique: [0004] In the prior art, a grinding plate for a sanding machine adopts a grinding block, which is to bond an elastic cushion to the bottom of the cuboid block, then wrap graphite cloth outside, and fix it to the two side walls of the cuboid block with nails or bolts. On the top, the graphite coating wrapped with graphite cloth faces down, and is pressed on the cuboid grinding block through the pressure member. The grinding block wrapped with graphite cloth is pressed on the back of the fast-moving grinding belt, and its function is to apply Press the abrasive belt so that the abrasive grain surface of the abrasive belt is tightly pre...

AI Technical Summary

Problems solved by technology

[0005] There are three defects in the film pressing block of the prior art. One is that it is troublesome to make and it is inconvenient to use a variety of different materials to make it, so it has poor grinding compatibility with workpieces of different materials. Quick installation and quick replacement. It would be wasteful to throw away the entire grinding block and replace it with a new one. Third, the graphite cloth coating is only a layer of natural flake graphite, which has good lubricity but is not wear-resistant and has a short service life.
