Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of forming knives, in particular to an internally cooled forming knife. Background Art
[0002] The most common cooling method for metal processing is cutting fluid, but traditional overflow cooling lubricants often encounter their physical limits, so there are tools with internal cooling function that can direct cutting fluid to the processing part, that is, internal cooling tools. The overall internal cooling tool is mostly a drill bit, which has two spirally crossed inner holes, allowing compressed air, oil or cutting fluid to pass through and reach the tool tip, playing a role in cooling the tool and workpiece, and can wash away chips, which is particularly suitable for deep hole high-speed processing.
[0003] In the prior art, the coolant channel inside the internally cooled tool is connected to an external cooling source to achieve liquid supply. However, the existing internally cooled turning tool is limited by its own structure, and the coolant injection angle is relatively fixed and not very flexible. Therefore, we need to provide an internally cooled forming tool. Utility Model Content
