Description

Technical Field

[0001] The utility model belongs to the technical field of machining tools and relates to a toothed blade, in particular to a special-shaped toothed blade. Background Art

[0002] Insert blades are cutting tools with a layer of high hardness material embedded in the blade base. This design is intended to improve the blade's wear resistance, cutting efficiency and processing accuracy.

[0003] The traditional insert cutter is fixed to the tool holder by bolts and other parts. Usually, multiple processing positions are set. The processing position can be replaced by disassembling the rotating blade, which has the advantages of convenience in use.

[0004] However, during processing, the tool may wear out due to overheating and other conditions, thus affecting the processing accuracy. Although cooling media such as coolant will be sprayed to the blade through an external duct, meaningful processing will produce debris, or the processing position will change, causing the coolant to be misaligned with the cutting processing position. Summary of the invention

[0005] The utility model aims to solve the above problems existing in the prior art and provides a special-shaped insert blade with precise heat dissipation and cooling.

[0006] The purpose of the utility model can be achieved through the following technical solutions: a special-shaped toothed blade, characterized in that it includes a blade body, a plurality of centrally symmetrical cutting positions are provided on the blade body, a mounting hole is provided at the center of the blade body, and mounting surfaces are provided on both sides of the blade body, a plurality of through holes are opened on the mounting surfaces, guide grooves connecting the through holes are provided on the mounting surfaces, a protective cover is provided on the mounting surface, a clamping block for clamping the mounting hole is provided at the center of the protective cover, a guide opening is provided on the protective cover, and the guide opening is provided on the inner side of the processing position.

[0007] In the above-mentioned special-shaped insert blade, a limit strip is provided on the protective cover, and the limit strip is clamped on the top of the guide groove, and a guide hole communicating with the guide opening is provided on the guide groove.

[0008] In the above-mentioned special-shaped insert blade, a pressure block is provided in the guide hole.

[0009] In the above-mentioned special-shaped insert blade, a through groove is provided on the upper side wall of the protective cover.

[0010] In the above-mentioned special-shaped insert blade, both ends of the mounting hole are provided with clamping rings, and the bottom of the clamping block is provided with a clamping convex ring.

[0011] Compared with the prior art, the special-shaped insert blade prevents the cooling water from corroding the mounting bolts by setting a protective cover on the blade mounting surface, and sets a guide management on the blade. By opening a guide groove to guide the water and squeezing and spraying it, the cutting position is centrally cooled, which reduces loss and increases service life. The protective cover has a detachable structure and can be reused, reducing the cost of use. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0018] The following are specific embodiments of the present invention and the accompanying drawings to further describe the technical solution of the present invention, but the present invention is not limited to these embodiments.

[0019] like Figure 1 , 2 As shown in Figures 3, 4 and 5, the special-shaped toothed blade comprises a blade body 4, on which are provided a plurality of centrally symmetrical cutting positions 3, a mounting hole 7 is provided in the center of the blade body 4, and mounting surfaces 6 are provided on both sides of the blade body 4, on which a plurality of through holes 8 are opened, and on the mounting surfaces 6 are guide grooves 5 connected to the through holes 8, a protective cover 2 is provided on the mounting surface 6, a clamping block 10 for clamping the mounting hole 7 is provided in the center of the protective cover 2, and a guide opening 1 is provided on the protective cover 2, and the guide opening 1 is arranged on the inner side of the processing position. After the blade is installed, cooling water flows in from the through hole 8 opposite to the processing position being cut, is guided by the guide groove 5, avoids the mounting hole 7, and prevents corrosion of the mounting bolts, and the coolant is aligned with the cutting position 3 being processed through the guide opening 1, and the cutting position 3 is centrally cooled and flushed, and the through hole 8 at the bottom of the cutting position 3 involved in the processing is blocked by the tool holder, and the water flows to the cutting position 3.

[0020] Preferably, a limit strip 12 is provided on the protective cover 2, and the limit strip 12 is clamped on the top of the guide groove 5. The guide groove 5 is provided with a guide hole 13 connected to the guide opening 1. The limit strip 12 increases the connection strength between the protective cover 2 and the blade body 4 to prevent the protective cover from being detached from the installation due to erosion.

[0021] Preferably, a pressure block 14 is provided in the guide hole 13, and the pressure block 14 pressurizes and guides the water flow to further increase the cooling effect.

[0022] Preferably, a through groove 15 is provided on the upper side wall of the protective cover 2. When disassembling, one side of the protective cover 2 can be opened by prying the through groove 15, which facilitates disassembly and assembly.

[0023] Preferably, both ends of the mounting hole 7 are provided with a clamping ring 9, and the bottom of the clamping block 10 is provided with a clamping convex ring 11. The clamping ring 9 and the clamping convex ring 11 are engaged with each other, so that the mounting cover is installed more firmly.
