Description

Technical Field

[0001] The utility model relates to the technical field of supporting blades, in particular to an equipment supporting blade. Background Art

[0002] The blade usually refers to the component on the grinding machine used to support and fix the workpiece. The blade provides a stable foundation to ensure that the workpiece does not move during the grinding process. It can also help to accurately position the workpiece to ensure the accuracy and consistency of grinding. The blade is generally made of cemented carbide in use. Cemented carbide has good wear resistance. However, if cemented carbide is used directly for support, the blade is prone to cracking due to poor toughness and cannot withstand the vibration impact of the workpiece. Utility Model Content

[0003] In order to overcome the above-mentioned shortcomings, the utility model aims to provide a technical solution that can solve the problem of large production tolerance of workpieces when a carbide blade is supported.

[0004] To achieve the above objectives, the present invention provides the following technical solutions: a device supporting a blade, comprising a substrate, above which a support member for supporting a workpiece is provided, wherein the support member is a carbide layer in contact with the workpiece and a high-speed steel layer in contact with the substrate.

[0005] As a further solution of the present invention: the cemented carbide layer is located at the top end of the support member, and the high-speed steel layer is located at the bottom end of the cemented carbide layer.

[0006] As a further solution of the present invention: a connecting piece is provided above the substrate, and the connecting piece is located between the substrate and the supporting piece.

[0007] As a further solution of the present invention: push and pull push and release areas are formed above the base plate and on both sides of the connecting piece.

[0008] As a further solution of the present invention: the surface of the cemented carbide layer and the top of the substrate form an angle α, and the angle α is an acute angle.

[0009] As a further solution of the present invention: the top of the high-speed steel layer forms an angle β with the top of the substrate, the angle β is an acute angle, and the angle β is 30°.

[0010] As a further solution of the present invention: the cemented carbide layer and the high-speed steel layer are connected together by a welding process.

[0011] As a further solution of the present invention: the bottom of the base plate is a flat bottom that can cooperate with the pad.

[0012] As a further solution of the present invention: the angle α is 30°.

[0013] As a further solution of the present invention: the angle β is 30°.

[0014] Compared with the existing technology, the beneficial effect of this technical solution is that the toughness of the entire blade can be increased by combining the material layers in the support member, so that the tungsten steel will not crack due to poor toughness while serving as a supporting material.

[0015] Additional aspects and advantages of the present invention will be given in part in the following description and will become apparent from the following description or learned through practice of the present invention. BRIEF DESCRIPTION OF THE DRAWINGS

[0022] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0023] See also Figure 1-3 A device supports a blade, including a base plate 1, a support member 2 for supporting a workpiece is provided above the base plate 1, the support member 2 is a cemented carbide layer 21 in contact with the workpiece and a high-speed steel layer 22 in contact with the base plate 1. The toughness of the entire blade can be increased by combining the material layers in the support member, so that the tungsten steel will not crack due to poor toughness while serving as a supporting material.

[0024] In some embodiments: the carbide layer 21 is located at the top of the support 2, and the high-speed steel layer 22 is located at the bottom of the carbide layer 21. The carbide layer 21 is tungsten steel, which has good wear resistance. In the process of tungsten steel supporting the workpiece, the workpiece will rotate due to the guide wheel of the grinder. Therefore, the wear resistance of tungsten steel can make tungsten steel have a good service life. At the same time, the high-speed steel layer 22 is white steel, which has good toughness, while tungsten steel has poor toughness. Therefore, when the carbide layer 21 supports the workpiece, the vibration and impact of the workpiece can be transmitted to the high-speed steel layer 22. The high-speed steel layer 22 can withstand the impact by relying on its strong toughness, thereby avoiding the cracking of the blade.

[0025] A connecting member 11 is provided above the substrate 1, and the connecting member 11 is located between the substrate 1 and the support member 2. A push-and-pull area 12 that can be pushed and pulled is formed above the substrate 1 and on both sides of the connecting member 11. The connecting member 11 can fix the connecting support member 2 above the substrate 1, so that the substrate 1 can move with the support member 2, which is convenient for the user to adjust the position of the support member 2. The push-and-pull area 12 formed between the substrate 1 and the connecting member 11 can facilitate the user to pull or push the substrate 1, and can also reduce the volume of the substrate 1, making it easier for the user to move the substrate 1.

[0026] In some embodiments: the surface of the cemented carbide layer and the top of the substrate form an angle α, which is an acute angle and is 30°. The top of the high-speed steel layer 22 forms an angle β with the top of the substrate 1, which is an acute angle and is 30°. The cemented carbide layer 21 and the high-speed steel layer 22 are connected together by a welding process. The bottom of the substrate 1 is a flat bottom that can cooperate with the pad. The 30° angle design between the cemented carbide layer 21 and the high-speed steel layer 22 allows the cemented carbide layer 21 to be welded without having to distinguish the front and back sides during the welding process, and welding can be performed quickly. The connection between the cemented carbide layer 21 and the high-speed steel layer 22 through a welding process can reduce the production cost of the support 2. When the height of the support 2 cannot support the workpiece, the pad can be placed on the bottom of the substrate 1. Because the bottom of the substrate 1 is flat, it can fit well with the pad, thereby increasing the height of the support 2.

Therefore, the embodiments should be considered in all respects as illustrative and non-restrictive, and the scope of the present invention is defined by the appended claims, not the foregoing description, and all variations within the meaning and range of equivalents of the claims are intended to be encompassed within the present invention.
