A kind of cooling ring and its cutting tool

Abstract

The invention discloses a cooling ring and a cutting tool thereof. The cooling ring includes an annular body. The annular body includes an upper surface, a lower surface, and an inner peripheral surface and an outer peripheral surface connecting the upper surface and the lower surface. The ring-shaped inner groove is opened in the circumferential direction of the ring-shaped body, and more than one cooling hole is opened on the lower surface. The cooling hole communicates with the inner groove. Collective, simple in structure, easy to process and wide in use. A liquid storage chamber for storing coolant is provided on the tool peripheral surface between the cutting part and the clamping part of the cutting tool, and a drainage chamber is provided on the tool peripheral surface of the clamping part. The liquid storage chamber communicates with the drainage groove, and also includes the above-mentioned cooling ring. The cooling ring is installed outside the liquid storage chamber, and the inner peripheral surface cooperates with the liquid storage chamber to form a sealed cavity that communicates with the inner groove. The cooling liquid can pass through the Drainage slots, liquid storage chambers, inner grooves and cooling holes are sprayed to the cutting edge, with good cooling effect, low cost and easy installation and positioning.

Description

technical field [0001] The invention relates to the field of metal cutting, in particular to a cooling ring and a cutting tool thereof. Background technique [0002] The internal cooling tool with its own cooling structure has low cutting temperature and high chip removal efficiency. It not only has long cutting life, but also has good surface quality and high dimensional accuracy. It has a wide application prospect in theory. [0003] However, the internal cooling tools in the prior art usually need to set complex cooling channels inside, and even need to set multiple intersecting cooling channels inside. The cooling channels inside the tool are difficult to manufacture and the cost is high, especially when hard materials are used. The manufactured high-strength cutting tools need to use electric sparks for material removal when machining cooling channels, which results in very low processing efficiency, which increases processing costs and leads to a decline in the cost pe...

Problems solved by technology

[0003] However, the internal cooling tools in the prior art usually need to set complex cooling channels inside, and even need to set multiple intersecting cooling channels inside. The cooling channels inside the tool are difficult to manufacture and the cost is high, especially when hard materials are used. The high-strength tool is manufactured, and the cooling channel needs to be removed by electric sparks, which is very low in processing efficiency and increases the processing cost, resulting in a decrease in the cost performance of the cutting tool

Due to the low cost performance, in the actual cutting process, the application range of cutting tools with internal cooling structure is limited, and it is difficult to be widely used
