[0020] Please refer toFigures 1-5 , the present utility model provides a high-efficiency cutting tool for die steel, which includes a tool shank 1. A tool holder 2 is fixedly installed at the end of the tool shank 1. A positioning groove 3 is opened at one end of the tool holder 2 away from the tool shank 1. At the same time, the size of the positioning groove 3 is adapted to that of the tool head 8, and the tool head 8 is clamped inside the positioning groove 3. A cutting edge 7 is opened at the end of the tool head 8, and a through hole 9 is opened in the middle of the tool head 8. At the same time, the size of the through hole 9 is adapted to that of the fixing bolt 11, and a threaded hole 4 is opened on the middle surface of the positioning groove 3. The fixing bolt 11 passes through the through hole 9 on the tool head 8 and is screwed and fixed inside the threaded hole 4.

[0021] As a preferred embodiment, both the positioning groove 3 and the tool head 8 are square, and the thickness of the tool head 8 is equal to the depth of the positioning groove 3.

[0022] As a preferred embodiment, cutting edges 7 are provided at the four corners of the tool head 8, and the cutting edges 7 are arranged directly above the notch 5. At the same time, the notch 5 is opened at the end of the positioning groove 3, and the notch 5 is arc-shaped.

[0023] As can be seen from the above, during use, cutting edges 7 are provided at the four corners of the tool head 8. When a set of cutting edges 7 on it becomes dull and unable to cut after long-term use, at this time, the tool head 8 is disassembled. After the tool head 8 is rotated, the dull cutting edge 7 moves out of the cutting station at the top of the notch 5, and the brand-new cutting edge 7 moves into the cutting station at the top of the notch 5, thereby greatly extending the service life of the entire tool head 8. During long-term continuous cutting processing, there is no need to replace the entire tool head 8 just because a single cutting edge 7 is worn, saving costs; since the service life of the tool head 8 is extended and the replacement frequency of the tool head 8 is reduced, the procurement and maintenance costs of the tool are reduced.

[0024] As a preferred embodiment, a guide seat 10 is fixedly installed on the side wall surface of the tool head 8, and a guide groove 6 is opened on the side wall of the positioning groove 3. At the same time, both the guide groove 6 and the guide seat 10 are dovetail-shaped structures.

[0025] As can be seen from the above, during use, the operator holds the tool head 8 and inserts the guide seat 10 at the end of the tool head 8 into the guide groove 6. At this time, the tool head 8 is clamped inside the positioning groove 3. At this time, the threaded hole 4 and the through hole 9 are in a communicating state, which is convenient for the fixing bolt 11 to pass through the through hole 9 and be screwed and fixed inside the threaded hole 4, completing the rapid positioning and installation work of the tool head 8, reducing the installation time of the tool head 8, reducing the interruption time during production, and thus improving the processing efficiency of the steel die;

[0026] As a preferred embodiment, the sizes of the guide seat 10 and the guide groove 6 are adapted, and the guide seat 10 is inserted into the guide groove 6. At the same time, the depth of the guide groove 6 is equal to the height of the guide seat 10.

[0027] As a preferred embodiment, the cutter head 8 is positioned and installed on the positioning groove 3 through the guide seat 10 and the guide groove 6, and the cutter head 8 is a detachable structure on the positioning groove 3.

[0028] Working principle: When in use, the operator holds the cutter head 8, inserts the guide seat 10 at the end of the cutter head 8 into the inside of the guide groove 6. At this time, the cutter head 8 is clamped inside the positioning groove 3, and the screw hole 4 and the through hole 9 are in a communicating state, facilitating the fixing bolt 11 to pass through the through hole 9 and be screwed and fixed inside the screw hole 4, completing the rapid positioning and installation work of the cutter head 8, which can reduce the installation time of the cutter head 8 and reduce the interruption time during production, thereby improving the processing efficiency of the steel mold; the cutting edges 7 are provided at the four corners of the cutter head 8. When a set of the cutting edges 7 on it becomes dull and cannot perform cutting after long-term use, at this time, the cutter head 8 is disassembled, and after the cutter head 8 is rotated, the dull cutting edges 7 are moved out of the cutting station at the top of the notch 5, and the brand-new cutting edges 7 are moved into the cutting station at the top of the notch 5, thus greatly prolonging the service life of the entire cutter head 8. During long-term continuous cutting processing, there is no need to replace the entire cutter head 8 just because a single cutting edge 7 is worn, saving costs; due to the extended service life of the cutter head 8, the replacement frequency of the cutter head 8 is reduced, and the procurement and maintenance costs of the tool are lowered.
