Problems solved by technology

[0002] The various polishing wheels currently produced have the following defects: ①Low polishing efficiency, such as hemp wheels (several layers of sisal are sewn together, and only the end face participates in grinding)
There is following shortcoming in the sisal fiber buffing wheel prepared with this kind of method: one, because the sisal fiber length used has only 4-12cm, thereby buffing wheel comes off easily in use sisal fiber, makes the service life of buffing wheel shortening; 2. Due to the limitation of needle punching density, it is impossible to ensure that any part of the polishing wheel can be tightly bonded, which will also affect the use effect of the polishing wheel
The polishing wheel produced by this method is molded and has no porous material, so the whole structure is very dense and has no gaps, which will easily cause the surface temperature of the grinding wheel to rise during the entire grinding process. The workpiece to be ground will also have a large surface temperature rise, which will cause stress concentration and may contaminate the surface of the workpiece to be ground

Embodiment 1

[0027] Example 1 (to explore the relationship between the mixing mass ratio of phenolic resin and natural fiber rope and the polishing effect).

[0028] Recipe 1:

[0029]

[0030] Sample making

[0031] 1.1 Process route

[0032] 1.2.1 Glue on the hemp rope: Roll and coat a circle of glue on the processed sisal fiber rope (: 65% modified liquid phenolic resin solution, filler: 35%, glue solid content: 75-77% , the amount of glue is: 0.7-0.8g per gram of sisal fiber rope), and then baked at 70±2°C for 30min.

[0033] 1.2.2 Wrap the glued hemp rope on the mold according to the established route, then put it into the mold cavity, press and shape it, and bake it at 120°C for 4-6 hours (the flat grinding wheel is cured for 4 hours, and the circular grinding wheel is cured for 6 hours) , slowly lowered to room temperature and then out of the oven, unmoulded.

[0034] 1.3 The production pattern of this test is: flat polishing wheel: the outer diameter is 4 inches (101.6-103mm...

Abstract

The invention discloses a polishing wheel containing fiber ropes. A polishing disk of the polishing wheel is composed of the fiber ropes, and the fiber ropes are bound by binder. By regulating the proportion between the fibers and the binder, the polishing effect and grinding efficiency of the polishing wheel can be controlled.

Description

technical field [0001] The invention relates to a polishing wheel containing a fiber rope, which belongs to the field of abrasive tools. Background technique [0002] The various polishing wheels currently produced have the following defects: 1. The polishing efficiency is low, such as hemp wheels (several layers of sisal are sewn together, and only the end faces participate in grinding). Chinese patent CN1238254A discloses a sisal fiber polishing wheel, and discloses that its preparation method is: using a needle loom to make sisal short fibers into felt-like blanks, and then laminating 2-4 layers of sisal felt-like blanks , Sewn into a sisal fiber polishing wheel. There is following shortcoming in the sisal fiber buffing wheel prepared with this kind of method: one, because the sisal fiber length used has only 4-12cm, thereby buffing wheel comes off easily in use sisal fiber, makes the service life of buffing wheel 2. Due to the limitation of needle punching density, it ...
