Description

Technical Field

[0001] The utility model relates to the technical field of cutting processing, in particular to a novel multi-blade and multi-station forming tool. Background Art

[0002] In the Figure 6 The blank of the part shown is processed into Figure 7 The manufacturing process for the part shown above often requires the use of multiple cutting tools due to the unique structure of the part. However, frequent tool changes reduce cutting efficiency and increase tool costs. Furthermore, alloy forming tools suffer from poor edge durability during high-intensity, continuous machining, significantly increasing production costs. Therefore, the design of a new multi-blade, multi-station forming tool is urgently needed. Utility Model Content

[0003] The main purpose of the utility model is to provide a novel multi-blade and multi-station forming tool for solving the problems mentioned in the background technology.

[0004] In order to achieve the above purpose, the technical solution adopted by the utility model is as follows:

[0005] A novel multi-blade, multi-station forming tool comprises a toolholder with a cutting blade mounted on one end. The cutting blade is triangular in shape, with CBN composite plates on three sides. The cutting blade has an arc-shaped tip, flanked by a first cutting edge and a second cutting edge. The first cutting edge comprises a first and a second intersecting plane, with a circular arc transition between them. The CBN composite plate supports the first and second cutting edges and the cutting blade tip. A clearance angle is provided below the cutting blade tip.

[0006] Furthermore, the arc radius of the cutting edge of the cutting blade is 0.3 mm.

[0007] Furthermore, the included angle between the clearance angle and the plumb line is 11°.

[0008] Furthermore, the cutting blade is made of cemented carbide.

[0009] This utility model also includes other components that enable the normal use of the new multi-blade, multi-station forming tool. These devices or components all utilize conventional technologies in the art. Furthermore, devices and components not otherwise specified in this utility model, such as the tool handles described herein, all utilize conventional technologies in the art. During implementation, appropriate device or component models can be selected based on the specific work scenario.

[0010] The working principle of this utility model is that the cutting tool is equipped with a first cutting edge, a second cutting edge, and a cutting tip to meet the processing requirements of different positions on the part blank, reducing the frequency of tool changes and improving work efficiency. In addition, the use of CBN composite sheets as the carrier of the first cutting edge, the second cutting edge, and the cutting tip makes the cutting tool more durable and significantly reduces production costs due to the advantages of CBN composite sheets such as high wear resistance, good heat dissipation, high hardness, excellent impact resistance, and stable chemical properties.

[0011] Compared with the prior art, the present invention has the following beneficial effects: 1. It reduces the frequency of tool changes and improves work efficiency. 2. The cutting tool is more durable and significantly reduces production costs. BRIEF DESCRIPTION OF THE DRAWINGS

[0020] The present invention will be described in further detail below with reference to the accompanying drawings and specific implementation methods.

[0021] Example:

[0022] like Figures 1 to 7As shown, a novel multi-blade, multi-station forming tool includes a shank 6, with a cutting blade 4 mounted on one end. The cutting blade 4 is triangular in shape, with CBN composite plates 3 positioned on three sides. The cutting blade 4 has an arc-shaped tip 1, with a first cutting edge 2 and a second cutting edge 7 positioned on either side. The first cutting edge 2 is formed by a first plane 21 and a second plane 22 intersecting each other, with a circular arc transition between the first and second planes 21 and 22. The CBN composite plate 3 supports the first and second cutting edges 2 and 7, as well as the cutting blade tip 1. A clearance angle 5 is provided below the cutting blade tip 1.

[0023] Specifically, the arc radius of the blade tip 1 of the cutting blade 4 is 0.3 mm, the included angle between the clearance angle 5 and the vertical line is 11 degrees, and the material of the cutting blade 4 is cemented carbide.

[0024] The working principle of the novel multi-blade multi-station forming tool of the utility model is: a first cutting edge 2, a second cutting edge 7 and a tool tip 1 are arranged on a cutting tool 4 to meet the processing requirements of different positions of a part blank 8, reduce the frequency of tool change and improve work efficiency.

[0025] Specifically, refer to Figures 3-5 , Figure 3 is the working state of the first cutting edge 2 of the cutting tool 4, Figure 4 The tip 1 of the cutting blade 4 is performing straight cutting. Figure 5 This is the working state of the second cutting edge 7 of the cutting tool 4.

[0026] In addition, the CBN composite sheet 3 is used as a carrier for the first cutting edge 2, the second cutting edge 7 and the tip 1. Due to the advantages of the CBN composite sheet 3, such as high wear resistance, good heat dissipation, high hardness, excellent impact resistance and stable chemical properties, the cutting blade 4 is made more durable and the production cost is greatly reduced.
