Abstract

PURPOSE:To simplify and miniaturize a polishing device so that the replacement of abrasive materials, etc. may be easily made, in a process of polishing a steel plate or the like, by pressing a grinding and abrasive material against a running object to be ground and polished while the grinding and abrasive material is compressively formed such that abrasive is adhered to unwoven felt-like fabrics. CONSTITUTION:A suitable number of grinding and abrasive materials (a, a'...) which are formed such that abrasive is adhered to unwoven felt-like fabrics and which are taken off from their respective reels 2, are clamped between compressing and shaping wheels 1, 1a to be compressively formed by the rotation of the wheels, and then are compressed against an object to be ground and polished through guides 4, 4a. With this arrangement, the density of the grinding and abrasive materials (a, a'...) may be adjusted by regulating the clamping force of the compressing and shaping wheels 1, 1a in accordance with the kind of the object to be ground and polished and the condition of grinding and polishing, that is, the density is decreased upon mere washing but is increased upon polishing of a steel plate. Further, compressing and shaping belts 5, 5a may be used, instead of the compressing and shaping wheels.

Description

[Detailed Description of the Invention] The present invention relates to a method for grinding and polishing treated copper, non-punched maple, synthetic resin, stone, wood, etc., and is characterized by being optimal for surface cleaning of the various materials mentioned above. It is.

Conventionally, grinding (hereinafter simply referred to as "polishing 1") and surface cleaning of the above-mentioned various materials has been carried out exclusively using a roll-shaped grinding material (hereinafter simply referred to as "roll-shaped abrasive material 1").

That is, for example, when grinding various machines, etc., a plate or the like is held between a roll-shaped abrasive material and a backup roll provided opposite it, and the roll-shaped grinding material is rotated in the opposite direction to the running direction of the steel mill. However, since fx, there are disadvantages in that it takes time and effort to produce the roll-shaped abrasive material, the roll-shaped abrasive material itself is expensive, and the installation is also sloppy and large. The handling of the exchange, etc. of
, there was a drawback.

First, regarding the roll-shaped abrasive material itself, the roll-shaped abrasive material is generally made of a felt-like nonwoven fabric of a suitable rhinoceros grain coated with a thermosetting resin.
No. 21346, Japanese Patent Publication No. 50-39590).Usage 1: When producing a roll-like fabric using a felt-like non-woven fabric, the felt-like non-woven fabric taken in the form of a sheet is punched into a circle. As a result, the remaining part is completely wasteful and extremely uneconomical.
Thereafter, it was necessary to integrally form a flange onto the shaft, which had been prepared by applying pressure and heating.

According to the present invention, in addition to the above-mentioned punching, the shaft,
It is necessary to prepare flanges, etc.

Next, if we talk about the complexity and size of the equipment, when roll-shaped abrasive material is used, a rotation mechanism, backup roll, shaping device) are inevitably required, and all of these are not integrated into one. However, depending on the application, it may be necessary to provide a large number of abrasive grains, i.e., in the case of roll-shaped abrasive grinding, when grinding a steel plate, etc., and when obtaining the required grinding layer i, etc., in addition to adjusting the abrasive grains,
In some cases, it may be necessary to provide a large number of roll-shaped polishing phases.

According to the present invention, it is not necessary to rotate the abrasive material by δ,
There is no need for the device d for this, and in both cases, there is no need for a large electrician's key for pressurized reverse rotation, and it is also possible to adjust the contact pressure of the abrasive material against the material to be ground. There are many types of devices that can be used freely, polish perfectly even when the abrasive material to be ground is traveling at high speed, and can be made smaller and provided at a lower cost.

Next, we will talk about how to replace the ω1 grinding material. Rolled grinding material 1-111 needs to be rotatably supported on the frame side, and the replacement work when the part 71 is worn out is difficult. Once the line is in place.

In this respect, according to the present invention, the above operations are completely unnecessary.

An embodiment of the present invention will be described in detail below with reference to the drawings.

In Fig. 1, an appropriate number of pieces of abrasive material (α) (cLl(α)) with abrasive particles fixed to the felt-like non-mineral cloth are compressed and shaped. Width (1y1
An example is shown in which polishing is performed by applying pressure to multiple grinding and polishing (61) while performing compression molding using α).

In other words, wind an appropriate number of grinding abrasive materials (α) (α) (α) (α) (α) (α) to obtain the median (required in advance) on each reel (2+). Then, pull it out and hold it in the compression shaping width (11(lα)K) from the guide roller (3) (y), compress it into IIIy shape, pass it through the guide (41(4α)), and apply it to the abrasive material to be ground [b]. It applies pressure.

The above pressurization can be performed continuously while maintaining a constant pressure by applying a rotational force as shown by the arrow to the compression shaping width (1) (1α) in advance.

Note that the compression shaping width (11(lα)) may be in the form of a roll.

Further, it is preferable to provide an excessive coefficient of friction in the drawing of the compression shaping width (ll(lα)).

These can be made by providing unevenness or knurling on the circumferential surface, or by attaching a leaf material such as hard rubber.

With the above-mentioned VC configuration, the density of the clamping width (11 (1α) -m-) can be adjusted according to the Iff of the abrasive material to be ground 1, and if the pressing force is adjusted in conjunction with this, the amount of grinding can be adjusted by 2. Can be adjusted freely.

In other words, for simple cleaning, use abrasive material (α) (α)
(The density of αI------ is YI5', and it is possible to construct it as if it were rounded. On the other hand, when polishing steel plates, etc., it is possible to increase the density and use conventionally available natural stone or artificial stone. It can be made as hard as a grindstone.

Furthermore, it goes without saying that no punching or the like is required as in the conventional roll-shaped polishing phase.

In FIG. 2, an example is shown in which a compression shaping belt (51 (5α)) is used instead of the compression shaping width (11 (lα)).

In this case, the compression shaping is mainly done by maintaining the state of the inner pulley of the upper F for a long time with the compression shaping belt (51 (5a), so that it does not deform on the pressure surface, and in addition, the upper pulley (7
) (7α) to the upper inner gA11 pulley (61 (6α)
), the compression shaping belt (51 (5) is placed above the abrasive material (α) (α) (α>---
- You can get the effect of a smooth guide or compressed vertical shape.

Even in this example, the pressure is adjusted to 51 (5 (L)

As mentioned above, the present invention compresses and molds an abrasive material in which abrasive grains are fixed to a felt-like nonwoven fabric, and pressurizes the traveling abrasive material by lfC, which requires less manufacturing time than conventional roll-shaped abrasive materials. It is possible to greatly reduce the amount of the abrasive, the holder 1 can be made simple and compact, and the handling such as replacing the abrasive can be made easier.
