Description

Technical Field

[0001] The utility model relates to the technical field of machining cutting, in particular to a chip-splitting type inserted blade for horizontal mounting. Background Art

[0002] In the field of machining, the blade is the core component of the cutting tool, and its performance directly affects the machining efficiency and quality. As a common type of blade, the inserted blade for horizontal mounting is widely used in various cutting occasions. However, during the finish milling process, iron chips are generated, and some iron chips are very difficult to break. Eventually, due to the entanglement of the iron chips, a long strip of iron chips is formed, which not only damages the surface of the workpiece but also damages the blade body, affecting the machining accuracy and the blade life. Moreover, after long-term use, the traditional blade is prone to high temperature, affecting the machining accuracy and efficiency, and even may cause the blade to be damaged.

[0003] At present, although there are some blades with a cooling system on the market, most of them have complex designs, high costs, and poor effects on chip handling. Therefore, developing a blade that can not only effectively cool but also properly handle iron chips has become an urgent problem for those skilled in the art. Summary of the Utility Model

DETAILED DESCRIPTION OF THE EMBODIMENTS

[0030] The present utility model will be further described in detail below with reference to the accompanying drawings. The same components are denoted by the same reference numerals. It should be noted that the terms "front", "rear", "left", "right", "upper", "lower", "bottom surface" and "top surface" used in the following description refer to the directions in the drawings, and the terms "inner" and "outer" refer to the directions towards or away from the geometric center of a specific component, respectively.

[0031] The present utility model discloses a chip-splitting type inserted blade, as Figures 1 to 3 shown, which includes a cutter head 1, a fixed shaft 2 is arranged on the cutter head 1, a positioning hole 6 is arranged on the cutter head 1, the fixed shaft 2 is detachably connected to the positioning hole 6, a blade 3 is arranged on the fixed shaft 2, the center of the blade 3 is hollow, a stopper 7 is arranged at the top of the fixed shaft 2, the size of the stopper 7 is larger than the center of the blade 3, and at the same time, the stopper 7 is fixedly connected to the top of the fixed shaft 2, and both the stopper 7 and the fixed shaft 2 are cylindrical, the radius of the stopper 7 is larger than the radius of the fixed shaft 2. After placing the blade 3 on the cutter head 1, then connecting the fixed shaft 2 and the stopper 7 to the positioning hole 6, the stopper 7 can prevent the blade 3 from moving. The edge of the blade 3 is specially provided with cutting teeth 8, and these cutting teeth 8 are made of high-speed steel or cemented carbide, with extremely high hardness and good wear resistance, which can significantly improve the cutting efficiency and the service life of the blade 3. The cutting teeth 8 protrude from the top end of the cutter head 1, facilitating the cutting operation.

[0032] A plurality of cooling channels 4 are arranged on the cutter head 1, and the cooling channels 4 are used to cool down the blade 3. The cooling channels 4 include a first coolant outlet 41 and a second coolant outlet 42. The first coolant outlet 41 is aligned with the whole blade 3 to ensure that the coolant can completely cover the blade 3 to achieve the purpose of overall cooling. The second coolant outlet 42 is specifically for the cutting teeth 8 part for local enhanced cooling, so that the cutting teeth 8 can maintain a lower temperature during high-intensity cutting work and extend the service life. A space 11 for the coolant to impact is arranged between the second coolant outlet 42 and the blade 3, facilitating the buffering of the coolant when it impacts from the coolant outlet to prevent the coolant from counterattacking back to the second coolant outlet 42. A concave surface 10 structure is added to the cutter head 1, and this concave surface 10 is located opposite to the first coolant outlet 41. When the coolant sprays out from the first coolant outlet 41, it will first impact the whole blade 3 and then flow down along the curve of the concave surface 10. The concave surface 10 plays a role in collecting and guiding the coolant, ensuring that the coolant can smoothly flow back to the circulation system and avoiding waste.

[0033] Multiple V-grooves 5 are provided on the blade 3. These V-grooves 5 are located at the outer edge of the blade 3 and are V-shaped. During the cutting process, the V-grooves 5 can guide the iron chips generated by cutting to move along a specific direction, avoiding the accumulation or entanglement of iron chips on the surface of the blade 3. At the same time, the V-grooves 5 can also cut off overly long iron chips, reducing the adverse effects of iron chips on the cutting process and the life of the blade 3. There are protrusions 9 provided on the cutter head 1. These protrusions 9 correspond to the V-grooves 5 one by one, and they can provide additional support for the V-grooves 5 during the machining process, thereby dispersing the impact force received by the blade 3.

[0034] Working principle: A chip-splitting type inserted blade designed by the present utility model, during use, the blade 3 is fixed by the fixed shaft 2 on the cutter head 1, and the workpiece is cut by the cutting teeth 8 on the blade 3. During the cutting process, the coolant flows through the cooling channels 4 and is sprayed onto the blade 3 and the cutting teeth 8 from the first coolant outlet 41 and the second coolant outlet 42 respectively. Through the V-grooves 5 on the blade 3 and the protrusions 9 on the cutter head 1, the flow direction of the coolant and the iron chips is guided, and at the same time, the iron chips generated during the cutting process are cut off. Therefore, through the setting of the V-grooves 5 and the cooling channels 4, the chip-splitting type inserted blade 3 can not only cut off the generated iron chips but also cool the blade 3.

[0035] The above are all the preferred embodiments of this application. The protection scope of this application is not limited thereby. Therefore, all equivalent changes made according to the structure, shape, and principle of this application should be covered within the protection scope of this application.
