Description

Tool with chip removal function

The present invention relates to a woodworking tool, especially a tool with chip removal function.

Generally, when processing wood, users usually use different knives to process wood according to different processes and different positions.

However, the tools currently used to process wood on the market usually do not have the function of chip removal. Therefore, during the process of processing, the chips are likely to accumulate between the tool and the wood, resulting in tool wear and overheating of the tool. It is easy to affect the processing schedule because of the need to remove chips in a timely manner.

Therefore, the purpose of the present invention is to provide a tool with chip removal function.

Thus, a tool with chip removal function includes a knife body, a blade unit, and a guide unit.

The knife body extends along an axis and includes a coupling section and a knife section disposed oppositely along the axis. The cutter segment has a surrounding surface around the axis, and a first coupling groove recessed in the surrounding surface. The first coupling groove is opened toward the end opposite to the coupling section along the extending direction of the axis.

The blade unit includes a first main blade. The first main blade is disposed in the first coupling groove, and protrudes from the cutter segment along the extending direction of the axis. The material hardness of the first main edge is harder than the material hardness of the tool segment.

The guiding unit includes at least one first groove disposed around the axis and recessed in the surrounding surface and the first main edge.

The effect of the present invention lies in: by setting the at least one first groove, when the tool with the chip removal function is rotated and an object is processed, the generated chips can be along the tangent direction of the at least one first groove It is far away from the tool with chip evacuation function, so the chip can be prevented from accumulating between the tool with chip evacuation function and the object to affect the processing operation.

Referring to Figures 1, 2, and 3, the new tool with chip removal function is suitable for connecting a processing machine (not shown) and processing an object 1 (see Figure 6). The tool with chip evacuation function includes a knife body 2, a blade unit 3, a guide unit 4, and a positioning ring 5.

The cutter body 2 extends along an axis L, and includes a coupling section 21 and a cutter section 22 disposed oppositely along the axis L. The positioning ring 5 is sleeved outside the combining section 21 and is suitable for connecting to the processing machine. In this embodiment, the positioning ring 5 is fixed outside the coupling section 21 by mechanical compression.

The cutter section 22 has a surrounding surface 221 around the axis L, a first coupling groove 222 recessed in the surrounding surface 221, and a first coupling groove 222 recessed in the surrounding surface 221 and around the axis L A second coupling groove 223 is provided at an angular interval, and a drilling edge groove 224 is recessed on a surface of the cutter section 22 opposite to the coupling section 21. In this embodiment, the drilling edge groove 224 communicates with the first coupling groove 222 and the second coupling groove 223.

The blade unit 3 includes a first main edge 31 disposed in the first coupling groove 222, a second main edge 32 disposed in the second coupling groove 223, and a drill hole disposed in the drilling edge groove 224刀33. The first main edge 31, the second main edge 32 and the drilling edge 33 protrude from the tool segment 22 along the extending direction of the axis L, and the material hardness is harder than the material hardness of the tool segment 22.

Referring to FIGS. 3, 4 and 5, in this embodiment, the outlines of the first main edge 31, the second main edge 32 and the drilling edge 33 perpendicular to the axis L protrude from the surrounding surface 221 perpendicular to the The contour of the axis L.

The extending direction of the profile of the first main edge 31 perpendicular to the axis L intersects the extending direction of the profile of the drilling edge 33 perpendicular to the axis L. The extending direction of the profile of the second main edge 32 perpendicular to the axis L intersects the extending direction of the profile of the drilling edge 33 perpendicular to the axis L. In this embodiment, the drilling edge 33 is perpendicular to the contour of the axis L, the extension direction of the first main edge 31 is perpendicular to the contour of the axis L, and the second main edge 32 is also perpendicular to the The extension direction of the contour of the axis L.

The guide unit 4 includes three first grooves 41 disposed around the axis L and recessed on the surrounding surface 221 and the first main edge 31 and spaced apart from each other along the extending direction of the axis L, and three surround the The axis L is provided and recessed in the surrounding groove 221 and the second main edge 32 and spaced apart from each other in the second groove 42 along the extending direction of the axis L. The first grooves 41 and the second grooves 42 are misaligned with each other along the extending direction of the axis L, and each first groove 41 and each second groove 42 are opened around opposite ends of the axis L .

Each first groove 41 has a first groove area 411 recessed in the surrounding surface 221 and a second groove area 412 recessed in the first main edge 31. The groove width of the first groove region 411 along the extending direction of the axis L is substantially the same as the groove width of the second groove region 412 along the extending direction of the axis L. The shape of each second groove 42 is similar to that of each first groove 41, and the groove width of each second groove 42 formed in the surrounding surface 221 and the groove width formed in the second main edge 32 are substantially The same.

Referring to FIGS. 4, 6 and 7, before processing the object 1 with the tool with chip removal function, the user fixes the tool with chip removal function to the processing machine, and then uses the processing machine to drive the tool to discharge The cutter with a chip function rotates in a rotation direction X about the axis L, and causes the first main edge 31, the second main edge 32, and the drilling edge 33 to cut the surface of the adjacent object 1 to achieve the machining Features. The chips (not shown) generated during the cutting process will be away from the tool with chip removal function along the tangent direction of the first grooves 41 and the second grooves 42 due to inertia It will not accumulate between the tool with chip removal function and the object 1.

It is worth mentioning that, since the groove width of the first groove region 411 of each first trench 41 along the extension direction of the axis L and the groove width of the second groove region 412 along the extension direction of the axis L are substantially The groove width of each second groove 42 formed in the surrounding surface 221 is substantially the same as the groove width formed in the second main edge 32, so that the chips can be made in each first groove 41 and each The second groove 42 moves more smoothly.

In addition, since the first grooves 41 and the second grooves 42 are offset from each other along the extending direction of the axis L, the effect of chip breaking can be achieved, and the continuous accumulation of chips in the first grooves 41 and the Wait for the second groove 42 to increase friction.

It should be particularly noted that in this embodiment, the knife body 2 is connected to the processing machine through the positioning ring 5, however, the fixing method is not limited to this, and in other embodiments, it can also be The shape of the coupling section 21 is changed to match the tool chuck fixed to different types of processing machines.

In summary, by providing the first grooves 41 and the second grooves 42, when the tool with chip removal function is rotated and the object 1 is processed, the generated chips can move along the The tangent directions of the first groove 41 and the second grooves 42 are far away from the tool with chip removal function, so it is possible to avoid the accumulation of the chip between the tool with chip removal function and the object 1 to affect the processing operation, Therefore, it is indeed possible to achieve the purpose of new cost.

However, the above are only examples of the new model. When the scope of the new model cannot be limited by this, any simple equivalent changes and modifications made according to the patent application scope and patent specification content of the new model are still regarded as Within the scope of this new patent.
