[0039] It should be noted that, unless otherwise specified, the embodiments and features described in this application can be combined with each other. This application will now be described in detail with reference to the accompanying drawings and embodiments.
[0040] like Figure 1-4 As shown, this application relates to a split-type drilling, chamfering, boring, and forming tool. This split-type drilling, chamfering, boring, and forming tool includes a sub-tool 10; it can achieve good fixing and support effects, and at the same time, it can achieve good cooperation with other components, thereby achieving multiple functional effects.
[0041] Flange 101 is disposed around the sub-blade 10; flange 101 is a ring-shaped or plate-shaped structural member arranged around the sub-blade 10, which can provide support and connection between the sub-blade 10 and other components (such as the mother blade 20); through flange 101, the function of the sub-blade 10 can be expanded, such as fixing other tools or equipment.
[0042] The mother cutter 20 is connected to the flange 101; the mother cutter 20 is a cutting tool connected to the flange 101, usually used to assist in cutting or as a replacement part.
[0043] Two connecting holes 30 are respectively opened through the mother knife 20, and the two connecting holes 30 are arranged opposite to each other; the mother knife 20 has two holes for fixing the mother knife 20 to the flange 101; the opening allows the mother knife 20 to be fixed by a certain connector (such as bolts, pins, etc.); the two connecting holes 30 are arranged opposite to each other, so that they can be symmetrically arranged on the mother knife 20 to ensure balance and stability.
[0044] A connector is connected to the two connecting holes 30. The connector is a component used to pass through the connecting holes 30 of the mother knife 20 and fix the mother knife 20. The connector can be a bolt, screw, etc.
[0045] The female blade 20 is detachably mounted on the flange 101 of the female blade 10 by means of the connector cooperating with the two connecting holes 30.
[0046] Specifically, the connector fixes the female blade 20 to the flange 101 through two connecting holes 30, and the flange 101 surrounds the female blade 10; this allows the female blade 20 to work stably, while maintaining its detachability for easy maintenance and replacement.
[0047] Detachable design: The female knife 20 can be removed from the flange 101 by loosening the connector, which facilitates maintenance and replacement.
[0048] Stability: The fit between the two connecting holes 30 and the connector provides sufficient support to ensure that the mother knife 20 will not loosen during operation.
[0049] Modular structure: Flange 101, as an intermediate structure, allows for the separation and independent design of the mother knife 20 and the daughter knife 10, enhancing flexibility.
[0050] This application can solve the problem of products with many dimensions that cannot be machined in one go. For example, due to small gaps in some positions, grinding wheel interference prevents machining; it also solves the problem of some products, such as those with high requirements for coaxiality of inner holes and outer circles, which need to be machined together.
[0051] As can be seen from the above description, this application achieves the following technical effects:
[0052] In this embodiment, a detachable connection is adopted. By cooperating with the connector and the two connecting holes 30, the mother cutter 20 is detachably mounted on the flange 101 of the daughter cutter 10, achieving the purpose of detachable assembly of the daughter cutter 10 and the mother cutter 20. This achieves the technical effects of easy disassembly and assembly and reduced costs. It also solves the technical problems of existing forming cutters, which require customized special-shaped grinding wheels in the actual tool production process due to the large number of composite machining surfaces, thus increasing costs; and when encountering composite machining such as internal holes and boring holes at the same time, the grinding wheel machining interference often leaves one helpless.

It is understood that this structure of the sub-blade 10 is designed to ensure good tool function.
[0054] Furthermore, the sub-blade portion 102 is provided with a drilling edge 1021. This allows for effective drilling while preventing interference.
[0055] Furthermore, the sub-blade portion 102 is also provided with a first chamfering forming blade 1022. It can be understood that this can achieve a good chamfering forming effect, while also avoiding interference.
[0056] Furthermore, the mother blade 20 includes a mother blade cutting edge 201 and a mother blade shank 202, wherein the mother blade cutting edge 201 is connected to the mother blade shank 202, and the mother blade shank 202 is connected to the flange 101. It is understood that this structure of the mother blade 20 is designed to ensure good cutting tool function.
[0057] Furthermore, a boring blade 2011 is provided on the mother cutting edge 201. It is understood that this enables a good boring effect.
[0058] Furthermore, a second chamfering edge 2012 is also provided on the mother blade 201. It is understood that this can achieve a good chamfering effect while avoiding interference.
[0059] Furthermore, a gap 203 is formed on the mother blade 20 along the first direction and near the connecting hole 30, and the gap 203 is located between the two connecting holes 30. It can be understood that by forming the gap 203, a good assembly effect can be ensured. Here, the first direction is the axial direction of the mother blade.
[0060] Furthermore, the mother blade 20 also has a notch. It can be understood that by providing the notch, the weight of the mother blade can be reduced while preventing interference.
[0061] Furthermore, the flange 101 has an adjustment hole 1011 along its axial direction, and a length adjustment component is provided in the adjustment hole 1011. This allows for length adjustment, thus flexibly adapting to the needs of various application scenarios.
[0062] Furthermore, the sub-cutting edge 102 and the mother cutting edge 201 are made of cemented carbide, while the sub-handle 103 and the mother handle 202 are made of tool steel. This ensures good tool performance.
[0063] This application also has the following beneficial effects:
[0064] 1. The daughter blade 10 and the mother blade 20 can be separated into two independent products, and the daughter blade 10 and the mother blade 20 are manufactured separately, saving the cost of combining them together;
