Abstract

PURPOSE:To prevent the fall of a particle by fixing the abrasive grains having a uniform grain size only on the outside surface of a metal belt on the whole face by an electrodeposition layer. CONSTITUTION:The raw material of a metal plate is cut in the specific width in advance and formed in a cylindrical shape. The cylindrical metal plate is then rolled in a thin sheet like to form a metal belt 1 in a constant width, be repeatedly receiving the rotating push pressure from the in and out of each roll with its locating between an internal pressure roll 4 and external pressure roll 5. A desired metal grinding belt 10 is obtained by fixing the abrasive grains having almost uniform grain size by an electrodeposition means on the outer surface of this metal belt 1.

Description

Detailed Description of the Invention [Industrial Field of Application] The present invention is used for full-scale or partial grinding of metal parts, etc., and involves grinding the surface of the metal belt while rotating an endless metal belt. Metal grinding belt for grinding 611 parts by grain surface and its product Ti h'
1)-2.

[Prior Art] A normal grinding belt is made by using a bonding agent in a fibrous material of atoms, and using the bonding agent, a hard substance such as alumina particles or silicon carbide is mixed all over the abrasive surface to form an abrasive. , was made as a grinding belt.

However, the thickness of a belt made of fiber material is not uniform all over, so it is good when used for rough cutting, but when more precise grinding power is required, The flexibility was a drawback and there was a problem with the ability to add.

In addition, there is a problem with the binding ability of the binder to the fiber material.
Therefore, there was a problem that the particles could not easily fall off.

In addition, connecting fiber materials in an endless manner
Since the continuous viscous parts overlap and there is a difference in local J-noness, the surface of the belt is not necessarily smooth.

Also, lj'l +iL! As mentioned above, belts made of fiber materials are made by applying a binder to the fibers themselves to make them contain iron particles, so each wafer cannot be applied uniformly, and due to the soft nature of the fabric, it is difficult to grind. Differences occurred in degree, and there was a problem with the addition ability.

[Problems to be Solved by the Invention] The present invention attempts to solve the problems of the conventional art in an effective manner.The LI aspect of the present invention is to use a metal plate for the belt, and to reduce the constant 1' pitch of the belt. This method uses a metal grinding heald that holds the surface of the abrasive smoothly.

In addition, instead of using a bonding agent that is easy to use with a J/L difference in the thickness mud method, we use LI:
It is an object of the present invention to provide a method for spreading and fixing hard particles thereto by means of a step.

[Means for Solving the Problems] In order to achieve the target of 1", the metal grinding belt according to the present invention is mechanically pressed from both sides by metal rolls.

In addition, in the method of manufacturing a metal grinding belt, a metal plate material is cut into a predetermined width of a circle 1. '7I shape is formed between the upper part, the inner I-1 roll, and the outer Ff roll, and by reciprocating and receiving two 1111 rolling presses from the inside and outside of the valley roll, it is made into a -C plate shape. 11 - a lower punch extending to form an endless metal heddle of constant width, +i′l;
The abrasive grains having a substantially uniform particle size are fixed to the outer surface of the metal by an electric means 2'1 to the small metal heald surface.

It has an advantage of 1, and the durability is high.

Also, since 117r was fixed to the metal surface by electric <'t IM, that +1! The il Xi force is strong and the powder will not fall off.

In addition, in the method for manufacturing such a metal grinding belt, 1
) 7I Note: The surface of the metal bending belt is curved in 1', and in this 1, the 1' point goes up to Y and the angle of 1°lr becomes Xff.
Since it is mixed and fixed at the same time as 4"t, a belt with a constant length of 1" can be made.The mixing ratio of the P-nos and Kyochi "I-ko" can be adjusted to 1", so The belt can be configured as needed.

[Example] Hereinafter, a metal grinding belt according to the present invention will be explained based on FIG.

As shown in FIG. 1(a), this metal belt 10 is first assembled by joining the joint parts 3 and 1 of the metal toric body 2 using one stage of electron beam, laser beam, and plasma welding tube as flN>). to form a complete ring.

In another example, for example, a long thin plate is wound into a cylindrical shape in an inclined state, and the winding contacts are welded and cut into a predetermined width.

Alternatively, when using an electric resistance welded tube or when using a sealed vibrator, it is similarly welded to the necessary parts and then cut to a predetermined width.

In either method, the welded part 3 of the mating part expands and swells as shown in Figure 2.
In order to remove such an enlarged part, as shown in Fig. 3, as shown in Fig. 3, the enlarged part of the weld on the surface is enlarged using external roll 4 and inner LI: roll 5, and the metal belt is removed when opened. Expand the diameter to the required =1-method as 1.

FIG. 4 shows that after the diameter of the metal belt 1 explained in FIG. It is an explanatory diagram of attaching the roll 6 to one end and adding = while enlarging the normal diameter.

Thus, in the process shown in FIG. 4, the metal belt 1 is rolled to a required thickness of about 01 mm to 0.4 mm, and the surface is simultaneously made into a mirror-like finish.

Figure 5 is an explanatory diagram of applying paint 7 to the inner surface of the metal heald l, which was electrodeposited as one culm, and which was made by electrodeposition. .

In this example, since it is used as the grinding metal belt 10, = 11 and 110 rollers are arranged inside, so it is assumed that the sand quality II'i J' is equal to I j4'1. No. Therefore, this can be prevented by applying a coating of paint.

The 6th room is the same as the city uniform, and the train 2'; JM 20 has a matsuki liquid 21 on the river, east. In this case, it is preferable to perform the first copper plating on the 1st and 4th sides of the plate with nickel plating with an fI of 7 and a height of 1. The plating solution may be one commonly used for plating. For example, for copper plating, cuprous cyanide 201H/I, phthorium cyanide 30g/
l, charcoal 1'i! 2 Phthorium lF + a little bit of sodium hydride, bath temperature 40 degrees, dead flow density 0.5 A/dm2
It is said to be a row of beef.

As explained in FIG. 6, the plating liquid 21 contains hard abrasive grains 8 that are sorted into the same particles.

The abrasive grains 8 are about 50 to 100 microns in diameter, and after they are put into the liquid tank 20, they are always emptied (the inside of the liquid is stirred (1') with the feeding vibrator 23.
As a result, i+'i 8 moves γ2 in the port, and current is passed through the anode forest 22 to the metal heald 1, and at the same time it forms a plating layer and contains abrasive grains. The plating operation is rotated from time to time depending on the degree of electrodeposition so that the plating P and J are consistent and uniform.

In addition, 4); Even if a copper pyrophosphate plating solution is used instead of the steel plating solution mentioned in 1, the time is 1 minute.

Next, nickel plating may be instantaneously performed from step 1 of 1); j copper plating. By forming a nickel plating layer, the surface hardness and abrasive grain retention are strong, and the chipping property is improved.

The nickel plating solution is nickel sulfate with a current density of 200 A/dm2 and 3 A/dm2.

FIG. 7 is an explanatory diagram of the metal grinding belt 10 completed as shown in FIG. 6, and when the abrasive material on the back side is peeled off, a layer containing abrasive grains 8 is formed on the entire surface.

FIG. 8 is an enlarged cross-sectional view for explaining the surface shape of the ground metal belt IO. 1) (1) Since the abrasive grains 8 are floating in the liquid, they are attached over the entire surface at appropriate intervals.

Incidentally, since the grinding ratio belt IO is used to grind the object to be ground through synchronous movement, it must be flexible, and the above-mentioned plating ladle! Therefore, it is necessary to prevent the belt 1' from losing its elasticity.

A grinding metal belt is formed by the above-mentioned process, but since a plating layer of a uniform size j', j is formed on the metal surface that has been EV-rolled by the rolls, the abrasive grains contained in it are also contained in this layer. , and the overall accuracy is +t'? It was possible to construct a narrow belt, which enabled highly accurate processing.

In addition, since it is a metal belt, it is not stretched and can be used for long periods of time without any dimensional errors.

[Effects of the Invention] As is clear from the explanation below, according to the ground metal belt of the present invention, the belt can be uniformly and
Since the plate is completed with a uniform thickness, the plating layer electrodeposited on the surface is also formed with a uniform thickness. This allows highly accurate machining.

In addition, according to the method for manufacturing a grinding metal heald, a metal belt is rolled by an inner sand roll and an outer F10 roll, and abrasive grains are mixed into the mirror-like surface by an electrodeposited layer.
Since it is composed of a grinding belt, it does not stretch during use and cause defects, and it also allows for mass production of highly accurate belts with uniform thickness, making it easier to process. Easy and efficient.

Since the abrasive grains are reliably protected by the electrodeposited layer, the durability is much higher.
