Description

Technical Field

[0001] This utility model belongs to the technical field of diamond composite sheet, specifically relating to a split-type diamond mining composite sheet. Background Technology

[0002] Diamond composite sheets are made by sintering diamond micro powder and cemented carbide substrate under ultra-high pressure and high temperature conditions. They have the high hardness, high wear resistance and thermal conductivity of diamond, as well as the strength and impact toughness of cemented carbide. They are ideal materials for manufacturing cutting tools, drilling bits and other wear-resistant tools.

[0003] Existing diamond composite sheet bases and surface cutting blades are sintered as a single piece. When the cutting blades wear out during use, the entire diamond composite sheet needs to be replaced. The installation and disassembly process of the diamond composite sheet is cumbersome and will waste the intact base. Therefore, we propose a split-type diamond composite sheet for mining. Utility Model Content

[0004] The purpose of this invention is to provide a split-type diamond composite sheet to solve the problem mentioned in the background art that the existing diamond composite sheet base and surface blade parts are integrally sintered, and when the blade wears during use, the entire diamond composite sheet needs to be replaced. The installation and disassembly process of the diamond composite sheet is relatively cumbersome, and it will also cause the waste of the intact base.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a split-type diamond composite sheet, comprising a diamond base and a diamond surface layer. The upper surface edge of the diamond surface layer is provided with a wear-resistant arc-shaped chamfer. A plurality of cutting blades are integrally formed at the middle position of the upper surface of the diamond surface layer. These cutting blades are arranged in a circular array on the surface of the diamond surface layer. Both sides of each cutting blade have a cutting bevel. A plurality of external cutting teeth are installed on the upper surface of the diamond surface layer. An assembly post is fixedly installed on the lower surface of the diamond surface layer. An assembly slot for inserting the assembly post is formed on the upper surface of the diamond base. An assembly bolt is threaded onto the diamond base opposite the assembly slot. An assembly thread groove is formed on the surface of the assembly post for screwing the assembly bolt in. An injection cavity is formed on the diamond base. A connecting cavity is formed on the assembly post and communicates with the injection cavity. A conveying cavity is formed on the cutting blade and communicates with the connecting cavity.

[0006] The above-mentioned scheme uses a diamond base and a diamond surface layer in conjunction with assembly posts and assembly bolts. The diamond base and diamond surface layer are designed as separate units. After the assembly posts are inserted into the assembly slots, they are assembled using assembly bolts. When the diamond composite sheet wears during use, only the diamond surface layer can be removed and replaced, while the diamond base layer is retained. This facilitates disassembly and replacement and avoids the cumbersome process of disassembling and assembling the diamond base, which would affect work efficiency. By setting multiple cutting blades in conjunction with multiple external cutting teeth, the cutting blades, with their height decreasing from the center to the outside, achieve efficient cutting from point to surface. Combined with multiple external cutting teeth arranged in a horizontal spiral, multi-point synchronous cutting can be achieved, thereby significantly improving the cutting effect. The inclusion of an injection chamber, a connecting chamber, and a conveying chamber allows for the delivery of cooling water or lubricating oil during operation.

[0007] In a preferred embodiment, a plurality of alignment guides are fixedly installed on the inner wall of the assembly slot on the diamond base, and a plurality of alignment guide grooves are formed on the outer surface of the assembly post, with the alignment guides and alignment guide grooves used in conjunction.

[0008] With the above solution, when the assembly pin is inserted into the assembly slot, the alignment guide groove on the assembly pin is aligned with the alignment guide strip in the assembly slot. The alignment guide strip and the alignment guide groove work together to achieve the alignment and guidance effect of the assembly pin insertion, ensuring that the assembly bolt can be smoothly screwed into the assembly thread groove, thus improving the ease of use of the assembly operation.

[0009] In a preferred embodiment, the bottom end of the assembly plug is provided with a sealing groove, and the inner wall of the sealing groove is embedded with a sealing ring, the lower surface of the sealing ring being in contact with the inner wall of the assembly slot.

[0010] By adopting the above solution, the sealing groove is used in conjunction with the sealing ring to ensure good sealing characteristics between the assembly pin and the diamond base after the assembly pin is inserted into the assembly slot.

[0011] In a preferred embodiment, a recessed groove is formed on the surface of the diamond base opposite the position of the assembly bolt, and the head end of the assembly bolt is located inside the recessed groove.

[0012] By adopting the above solution, the recessed groove is used to accommodate the head end of the assembly bolt, which can prevent the head end of the assembly bolt from being exposed. This ensures both the aesthetics of the overall structure and the ease of tightening the assembly bolt.

[0013] In a preferred embodiment, the cutting blade is specifically triangular in shape, and the height of the upper surface of the cutting blade decreases sequentially from the center of the diamond facet towards the outside.

[0014] By adopting the above method, it can be ensured that the cutting blade can start cutting from the highest point of the center position, improving the cutting effect from point to surface.

[0015] In a preferred embodiment, several of the external cutting teeth are arranged in a horizontal spiral on the upper surface of the diamond surface layer.

[0016] Using the above scheme, multiple external cutting teeth can be arranged in a horizontal spiral, which can perform multi-point synchronous cutting on the cutting surface and improve the cutting effect.

[0017] Compared with the prior art, the beneficial effects of this utility model are:

[0018] This split-type diamond composite cutting tool uses a diamond base and a diamond facet layer, along with assembly posts and bolts. The diamond base and diamond facet layer are designed separately. After the assembly posts are inserted into the assembly slots, they are assembled using the assembly bolts. When the cutting tool wears during use, only the diamond facet layer can be disassembled and replaced, while the diamond base layer is retained. This design facilitates disassembly and replacement and avoids the cumbersome process of disassembling and assembling the diamond base, which could affect work efficiency.

[0019] This split-type diamond mining composite sheet uses multiple cutting blades in conjunction with multiple external cutting teeth. The cutting blades, with their height decreasing from the center to the outside, achieve efficient cutting from point to surface. Combined with multiple external cutting teeth arranged in a horizontal spiral, it enables simultaneous cutting at multiple points, thereby significantly improving the cutting effect. The inclusion of an injection chamber, a connecting chamber, and a conveying chamber allows for the delivery of cooling water or lubricating oil during operation. Attached Figure Description

[0026] Please see Figure 1-5 This utility model provides a split-type diamond mining composite sheet, including a diamond base 1 and a diamond surface layer 2. The upper surface edge of the diamond surface layer 2 is provided with a wear-resistant arc-shaped chamfer 3. Several cutting blades 4 are integrally formed in the middle of the upper surface of the diamond surface layer 2. The several cutting blades 4 are arranged in a ring array on the surface of the diamond surface layer 2. Both sides of the cutting blades 4 have cutting bevels 5. Several external cutting teeth 6 are installed on the upper surface of the diamond surface layer 2. An assembly post 7 is fixedly installed on the lower surface of the diamond surface layer 2. An assembly slot for inserting the assembly post 7 is opened on the upper surface of the diamond base 1. An assembly bolt 8 is threaded on the diamond base 1 opposite to the assembly slot. An assembly thread groove for screwing the assembly bolt 8 is opened on the surface of the assembly post 7. An injection cavity 9 is opened on the diamond base 1. A connecting cavity 10 connected to the injection cavity 9 is opened on the assembly post 7. A conveying cavity 11 connected to the connecting cavity 10 is opened on the cutting blades 4.

[0027] The diamond base 1 and diamond surface layer 2 are designed to be used in conjunction with assembly pins 7 and assembly bolts 8. The diamond base 1 and diamond surface layer 2 are designed as separate parts. After the assembly pins 7 are inserted into the assembly slots, they are assembled using the assembly bolts 8. When the diamond composite sheet wears during use, only the diamond surface layer 2 can be removed and replaced, while the diamond base layer is retained. This design facilitates disassembly and replacement and avoids the tedious disassembly and assembly of the diamond base 1, which would affect work efficiency. Multiple cutting blades 4 are used in conjunction with multiple external cutting teeth 6. The cutting blades 4, whose height decreases from the center to the outside, achieve efficient cutting from point to surface. In conjunction with multiple external cutting teeth 6 arranged in a horizontal spiral, multi-point synchronous cutting is achieved, thereby greatly improving the cutting effect.

[0028] Several alignment guides 12 are fixedly installed on the inner wall of the assembly slot on the diamond base 1. Several alignment guide grooves are opened on the outer surface of the assembly pin 7. The alignment guides 12 and the alignment guide grooves work together. When the assembly pin 7 is inserted into the assembly slot, the alignment guide groove on the assembly pin 7 is inserted directly into the alignment guide 12 in the assembly slot. The alignment guides 12 and the alignment guide grooves work together to achieve the alignment and guidance effect of inserting the assembly pin 7, ensuring that the assembly bolt 8 can be smoothly screwed into the assembly thread groove, improving the convenience of assembly operation.

[0029] The bottom end of the assembly insert 7 is provided with a sealing groove, and the inner wall of the sealing groove is embedded with a sealing ring 13. The lower surface of the sealing ring 13 fits against the inner wall of the assembly slot. The sealing groove is designed in conjunction with the sealing ring 13 to ensure good sealing characteristics between the assembly insert 7 and the diamond base 1 after the assembly insert 7 is inserted into the assembly slot.

[0030] A recessed groove is provided on the surface of the diamond base 1 at the position of the assembly bolt 8. The head of the assembly bolt 8 is located inside the recessed groove. The recessed groove is used to accommodate the head of the assembly bolt 8, which can prevent the head of the assembly bolt 8 from being exposed. This ensures the overall aesthetics of the structure and facilitates the tightening operation of the assembly bolt 8.

[0031] The cutting blade 4 is specifically triangular in shape, and the height of the upper surface of the cutting blade 4 decreases gradually from the center of the diamond surface layer 2 outwards. This ensures that the cutting blade 4 can start cutting from the highest point in the center, improving the cutting effect from point to surface.

[0032] Several external cutting teeth 6 are arranged in a horizontal spiral on the upper surface of the diamond surface layer 2. The arrangement of multiple external cutting teeth 6 in a horizontal spiral allows for multi-point synchronous cutting of the cutting surface, improving the cutting effect.

[0033] During use, multiple cutting blades 4, with their height decreasing sequentially from the center outwards, achieve efficient point-to-surface cutting while working on the diamond composite sheet. Combined with multiple horizontally spirally arranged external cutting teeth 6, multi-point synchronous cutting is achieved, significantly improving the cutting effect. When the blade body wears out and needs replacement, only the diamond surface layer 2 needs to be removed and replaced. During removal, the assembly bolt 8 is turned off, unlocking the assembly pin 7 and diamond base 1. The diamond surface layer 2 is then pulled upwards, causing the assembly pin 7 to disengage from the assembly slot, completing the removal. The new diamond surface layer 2 is then inserted through the assembly pin 7 into the assembly slot. During insertion, the alignment guide groove on the assembly pin 7 is aligned with the alignment guide strip 12 in the assembly slot, ensuring that the assembly bolt 8, when fully inserted, enters the assembly thread groove, thus completing the replacement and locking of the diamond surface layer 2. The inlet cavity 9, connecting cavity 10, and conveying cavity 11 allow for the delivery of cooling water or lubricating oil during operation.
