Description

Technical Field

[0001] This invention belongs to the field of grinding roller brush technology, and particularly relates to a grinding roller brush for beryllium bronze plate and foil materials. Background Technology

[0002] Among many copper processing products, beryllium copper sheet and strip is a high value-added product. It is the only copper alloy that combines mechanical, physical, chemical and corrosion resistance well. After solution treatment and aging heat treatment, it has high strength limit, elastic limit, yield limit and fatigue limit comparable to special steel. It also has high electrical conductivity, thermal conductivity, high hardness and wear resistance, and excellent creep resistance.

[0003] Due to the high reactivity of beryllium, the oxide film formed in existing technologies differs significantly from that of ordinary copper alloys. The oxide film on beryllium bronze has a dense and complex structure, with different oxides intertwined, requiring high-powered microscopy for detailed observation. In production practice, it has been found that the beryllium bronze oxide film is difficult to clean. Manufacturers often use non-woven fabric grinding rollers, increasing the cutting force by applying pressure to remove the dense and complex oxide film. However, under high pressure, the grinding rollers are prone to breakage at the root due to insufficient heat dissipation, severely impacting production progress and significantly increasing production costs. Summary of the Invention

[0004] To address the aforementioned technical issues, a beryllium bronze plate and foil grinding roller brush is proposed.

[0005] The present invention proposes a grinding roller brush for beryllium bronze plate and foil materials, comprising a brush barrel and brush blades; wherein:

[0006] The brush bucket is a high-strength bakelite bucket with heat dissipation holes evenly arranged along its length and circumference.

[0007] The brush is a non-woven fabric sheet containing high-cutting-force abrasive, and the non-woven fabric sheet contains angular and uniformly sized granular material for removing the oxide film from the surface structure of beryllium bronze plate foil.

[0008] The brush blades are fixed to the outer wall of the brush bucket with high-strength heat-resistant adhesive, and the brush blades are evenly distributed radially.

[0009] When the grinding roller is in operation, the heat at the connection between the brush barrel and the brush blade is dissipated through the heat dissipation holes.

[0010] According to the beryllium bronze plate and foil grinding roller brush of the present invention, heat dissipation holes with a diameter of 8-15mm are uniformly drilled on the outer wall of the brush barrel using a vertical drilling machine.

[0011] The beryllium bronze plate and foil grinding roller brush according to the present invention, wherein the granular material is one of alumina particles, silicon carbide particles or diamond particles.

[0012] According to the beryllium bronze plate and foil grinding roller brush of the present invention, the length of the brush blade is the same as the axial length of the brush barrel, and the width of the brush blade is 1 / 3 or 2 / 5 of the radius of the brush barrel.

[0013] According to the beryllium bronze plate, strip, and foil grinding roller brush of the present invention, in the working state, the contact mode between the brush blade and the strip surface of the beryllium bronze plate, strip, and foil is line contact.

[0014] This invention proposes a grinding roller brush for beryllium bronze plates, strips, and foils. The outer wall of the brush barrel has uniformly distributed through-holes. When the roller brush operates under high pressure, the heat at the connection between the brush blade and the brush barrel is dissipated through the heat dissipation holes on the outer wall of the brush barrel, effectively improving the service life of the roller brush. The brush blades are radially mounted on the outer wall of the brush barrel. When the brush barrel is working, the contact between the brush blades and the strip surface is line contact, effectively ensuring uniformity of the strip surface and improving product quality. The brush blades are made of non-woven fabric containing high-cutting-force abrasive, which can remove the fine and complex oxide film on the surface of beryllium bronze, improving production efficiency and ensuring product quality.

Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0021] This invention proposes a grinding roller brush for beryllium bronze plates and foils. For example... Figure 1 As shown, the grinding roller brush includes a brush barrel and brush blades; wherein: the brush barrel is a high-strength bakelite barrel with heat dissipation holes evenly arranged in its length and circumference; the brush blades are non-woven fabric sheets containing high-cutting-force abrasive, the non-woven fabric sheets containing angular and uniformly sized granular materials, used to remove the oxide film from the surface structure of beryllium bronze plate foil; the brush blades are fixed to the outer wall of the brush barrel with high-strength heat-resistant adhesive, and the brush blades are evenly distributed radially. In the working state, the heat at the connection between the brush barrel and the brush blades is dissipated through the heat dissipation holes.

[0022] Specifically, the beryllium bronze plate and foil nonwoven fabric roller brush with good heat dissipation proposed in this invention mainly consists of a brush barrel and brush blades. The brush barrel uses a high-strength bakelite barrel as the base to support the brush blades, which are made of nonwoven fabric containing high-cutting-force abrasive. The high-strength brush barrel has several heat dissipation holes evenly distributed in a crisscross pattern along its length and circumference. The brush blades contain sharp-edged, uniformly sized alumina, silicon carbide, or diamond particles. The length of the brush blades is the same as the axial length of the brush barrel, and the width is 1 / 3 to 2 / 5 of the roller brush radius. The brush blades are coated with high-strength, heat-resistant adhesive in a radial, evenly distributed pattern on the outer wall of the brush barrel.

[0023] like Figure 2 As shown, the length of the non-woven fabric containing high-strength abrasive is L, and the width is B, where B is equal to 1 / 3 to 2 / 5 of the radius of the brush barrel (roller brush). It is shown that high-strength, high-temperature resistant adhesive is used to bond it to the brush barrel.

[0024] According to the beryllium bronze plate and foil grinding roller brush of the present invention, the brush blade (such as...) Figure 3 The length of the brush blade is the same as the axial length of the brush bucket, and the width of the brush blade is 1 / 3 or 2 / 5 of the radius of the brush bucket.

[0025] According to the beryllium bronze plate and foil grinding roller brush of the present invention, heat dissipation holes with a diameter of 8-15mm are uniformly drilled on the outer wall of the brush barrel using a vertical drilling machine.

[0026] The beryllium bronze plate and foil grinding roller brush according to the present invention, wherein the granular material is one of alumina particles, silicon carbide particles or diamond particles.

[0027] like Figure 4 As shown, the brush bucket is made of high-strength bakelite in one piece, and is cut to the required length L according to the width of the strip. A vertical drilling machine is used to drill through holes with a diameter of 8-15mm evenly on the outer wall of the brush bucket.

[0028] According to the beryllium bronze plate, strip, and foil grinding roller brush of the present invention, in the working state, the contact mode between the brush blade and the strip surface of the beryllium bronze plate, strip, and foil is line contact.

[0029] The brush barrel (roller brush) obtained by this invention has a reasonable structural design. The perforated inner barrel design effectively improves the timely heat dissipation of the brush roller under high pressure and high speed. The brush blade contains sharp-edged, uniformly sized alumina, silicon carbide, or diamond particles. In summary, this roller brush has the advantages of good heat dissipation, strong cutting force, and long service life.

[0030] This invention proposes a grinding roller brush for beryllium bronze plates, strips, and foils. The outer wall of the brush barrel has uniformly distributed through-holes. When the roller brush operates under high pressure, the heat at the connection between the brush blade and the brush barrel is dissipated through the heat dissipation holes on the outer wall of the brush barrel, effectively improving the service life of the roller brush. The brush blades are radially mounted on the outer wall of the brush barrel. When the brush barrel is working, the contact between the brush blades and the strip surface is line contact, effectively ensuring uniformity of the strip surface and improving product quality. The brush blades are made of non-woven fabric containing high-cutting-force abrasive, which can remove the fine and complex oxide film on the surface of beryllium bronze, improving production efficiency and ensuring product quality.
