A grinding wheel with an L-shaped corrugated cutter head

Abstract

This paper proposes an L-shaped corrugated cutting head grinding wheel. The grinding wheel body surface is provided with a corrugated cutting head, which includes longitudinal cutting edges and transverse cutting edges. The transverse cutting edges are equidistantly connected to the wheel body surface in a transverse circumference, and one side of each transverse cutting edge is flush with the outer circle of the wheel body. Each transverse cutting edge has a longitudinal cutting edge at one end, which is longitudinally inclined and connected to the wheel body surface. One end of the longitudinal cutting edge is connected to one end of the transverse cutting edge. Chip guide grooves are provided on the wheel body surface at the included angle between the longitudinal cutting edge and the transverse cutting edge. The surfaces of both the longitudinal cutting edge and the transverse cutting edge are provided with corrugated grooves, which are inclined corrugated grooves. By changing the originally transversely parallel corrugated cutting edges to a combination of longitudinal and transverse cutting edges, the cutting efficiency of the grinding wheel can be improved by using a specific cutting edge angle. At the same time, the area of ​​the chip guide grooves on the grinding wheel surface can be increased as much as possible, thereby increasing the chip guiding efficiency of the grinding wheel.

Description

Technical Field

[0001] This article belongs to the technical field of corrugated tool head grinding wheels, specifically relating to a grinding wheel for an L-shaped corrugated tool head. Background Technology

[0002] With the development of superhard abrasive tool technology, especially sintered diamond grinding tools, the materials processing industry has placed higher demands on the performance parameters of sintered diamond tools. For cup-shaped diamond sintered grinding wheels, energy consumption during operation is a major concern in the context of promoting energy conservation and environmental protection. The weight of the grinding wheel is a significant influencing factor; the heavier the wheel, the higher the energy consumption required for high-speed rotation and the greater the performance degradation on supporting equipment. Therefore, designing a weight-reducing grinding wheel is becoming increasingly important. Furthermore, during dry grinding, if grinding chips cannot be quickly discharged from the grinding zone, it will significantly affect the grinding wheel's efficiency, and in severe cases, cause wear-resistant agglomeration, burning, and eventual scrapping of the grinding wheel.

[0003] However, the existing optimized grinding wheels all have the cutter heads arranged in a ring at equal intervals on the surface of the grinding wheel. The cutter head support ensures the discharge of cutting waste through the gap, and the cutter head is arc-shaped with the center of the cutter head facing the inside of the grinding wheel.

[0004] While this type of grinding wheel ensures lightweight design and significantly enhances chip removal efficiency, its cutting efficiency is greatly reduced due to the change in the shape of the cutting head. Therefore, optimizing the structure of the cutting head on the surface of the grinding wheel is essential. Summary of the Invention

[0005] This paper proposes an L-shaped corrugated cutting head grinding wheel. The grinding wheel body surface is provided with a corrugated cutting head, which includes longitudinal cutting edges and transverse cutting edges. The transverse cutting edges are equidistantly connected to the wheel body surface in a transverse circumference, and one side of each transverse cutting edge is flush with the outer circle of the wheel body. Each transverse cutting edge has a longitudinal cutting edge at one end, which is longitudinally inclined and connected to the wheel body surface. One end of the longitudinal cutting edge is connected to one end of the transverse cutting edge. Chip guide grooves are provided on the wheel body surface at the included angle between the longitudinal cutting edge and the transverse cutting edge. The surfaces of both the longitudinal cutting edge and the transverse cutting edge are provided with corrugated grooves, which are inclined corrugated grooves. By changing the originally transversely parallel corrugated cutting edges to a combination of longitudinal and transverse cutting edges, the cutting efficiency of the grinding wheel can be improved by using a specific cutting edge angle. At the same time, the area of ​​the chip guide grooves on the grinding wheel surface can be increased as much as possible, thereby increasing the chip guiding efficiency of the grinding wheel.

[0006] The wheel body is disc-shaped, with a mounting platform recessed in the middle. The mounting platform has a mounting screw hole at its center and several lightweight holes on its outer surface. The wheel shape ensures that the grinding wheel can work effectively, and the threaded hole allows for convenient and quick installation with the spindle. The lightweight holes are designed to reduce the weight of the grinding wheel and thus reduce energy loss during rotation.

[0007] The longitudinal blade is shaped like an arc-shaped key, and its surface has several parallel corrugated grooves. The inclination of the corrugated grooves on the longitudinal blade surface is opposite to the rotation direction of the grinding wheel. The transverse blade is also shaped like an arc-shaped key, and its surface has several parallel corrugated grooves. The inclination of the corrugated grooves on the transverse blade surface is the same as the rotation direction of the grinding wheel. The corrugated grooves are inverted trapezoidal in shape. Different blade directions are adapted to different corrugated groove directions, which better adapts to the rotation direction of the grinding wheel and improves grinding efficiency, thereby reducing energy consumption.

[0008] The chip guide groove has an irregular shape. One end of the chip guide groove is aligned with one end of the horizontal blade, and the other end of the chip guide groove is aligned with one end of the vertical blade. The chip guide groove is set through the surface of the wheel body. The L-shaped blade is adapted to maximize the area of ​​the chip guide groove while ensuring the strength and rigidity of the grinding wheel, thereby improving the chip discharge efficiency and reducing the risk of sintering.

[0009] Beneficial effects:

[0010] By changing the original horizontally parallel corrugated blades to a combination of vertical and horizontal blades, not only can the cutting efficiency of the grinding wheel be improved by using a specific blade angle, but the area of ​​the chip guide groove on the surface of the grinding wheel can also be increased. This maximizes the area of ​​the chip guide groove, thereby improving the chip guiding efficiency of the grinding wheel.

[0011] The wheel-shaped body ensures that the grinding wheel can work effectively, and the threaded hole allows for convenient and quick installation with the spindle, while the lightweight hole is designed to further reduce the weight of the grinding wheel and thus reduce the energy loss during rotation.

[0012] Different oriented cutting heads are adapted to different oriented corrugated grooves, which can better adapt to the rotation of the grinding wheel and improve grinding efficiency, thereby reducing energy consumption.

[0013] The L-shaped blades are designed to maximize the area of ​​the chip guide groove while ensuring the strength and rigidity of the grinding wheel, thereby improving the chip discharge efficiency and reducing the risk of sintering. Attached Figure Description

The corrugated groove on the longitudinal blade 2 is inclined to the left, and the corrugated groove on the transverse blade 3 is inclined to the right. When the length of the longitudinal blade 2 is greater than the width of the grinding wheel plane, the chip guide groove 4 cooperates with the longitudinal blade 2 and the transverse blade 3 to form a triangle, thereby increasing the area of ​​the chip guide groove 4.
