Embodiment Construction

[0030] Below in conjunction with Fig. 1-Fig. 4, the present invention is described in further detail as follows:

[0031] A multi-cutting-edge combined cutting tool includes a cutter bar 2, and more than one blade mounting mechanism is arranged at the front end of the cutter rod 2, and blades 1 are respectively arranged on the blade mounting mechanism.

[0032] The blade mounting mechanism is as follows: a blade mounting groove 8 is set at the front end of the knife bar 2, a groove 9 is established behind the blade mounting groove 8, a knife pad 3 is placed at the bottom of the blade mounting groove 8, and a blade 1 is arranged on the knife pad 3. The bottom of the T-shaped pressing plate 5 is embedded in the groove 9 , the front end of the T-shaped pressing plate 5 presses the blade 1 tightly, and the pressing plate screw 7 fixes the T-shaped pressing plate 5 on the cutter bar 2 .

[0033] In order to achieve linkage between the T-shaped pressure plate 5 and the pressure plat...

Abstract

The combined cutting tool with several cutting edges includes one cutter bar, and several cutting blade mounting mechanisms with separately mounted blades in the same or different entering angles. On the one hand, the combined cutting tool with several cutting edges can cut with its multiple cutting edges in doubled cutting depth, increased feed and doubled cutting efficiency. On the other hand, the present invention has flexible machining form, convenient operation, changeable number of cutting edges and adjustable entering angles. In addition, the cutting blades may be made of different materials, cubic boron nitride, diamond, hard alloy, etc. selected based on the machining requirement, machining cost and other factors.

Description

technical field [0001] The invention relates to a cutting tool, in particular to a multi-edge combined cutting tool. Background technique [0002] Ordinary cutting tools generally have a blade mounting mechanism and a cutting edge. With the development of modern metal rolling technology, a large number of high-hardness materials such as high-nickel-chromium, high-chromium-iron, and cast high-speed steel are widely used, which limits the application range and cutting efficiency of ordinary single-edged tools, especially in heavy-duty In the field of cutting processing, machine tools for heavy-duty cutting generally have good rigidity and high power. Due to the small size of the blade and few cutting edges, the choice of cutting depth is limited, so that the resources of high power and high rigidity of the machine tool cannot be used. Low cutting efficiency in heavy-duty machining applications of high-hardness materials such as high-nickel-chromium, high-chromium-iron, and ca...
