AI Technical Summary
Technical Problem
Traditional broaching tools have difficulty effectively penetrating the cutting edge and chip contact area, especially in deep hole or closed broaching.
Method used
Design a superhard alloy broaching tool with integrated self-cooling groove, including a main heat dissipation mechanism and a secondary heat dissipation mechanism. By setting an oil inlet groove, oil channel, main cavity, branch cavity, main vein and branch vein in the tool body, the coolant flows and is distributed inside the tool to achieve uniform cooling.
Benefits of technology
It improves the penetration and heat dissipation of coolant inside the tool, ensuring effective cooling of the tool in high-temperature environments and improving the efficiency and quality of broaching.

Abstract
The utility model discloses an integrated superhard alloy broaching cutter of self -cooling groove, including main heat dissipation mechanism and auxiliary heat dissipation mechanism, the main heat dissipation mechanism includes cutter body, the oil inlet groove of setting in cutter body top, the oil channel and main cavity of setting in cutter body inside and with oil inlet groove intercommunication, two shunt cavities of setting in cutter body inside, two shunt cavities are located main cavity both sides and with main cavity inside intercommunication. In the utility model, inject cooling liquid in the oil inlet groove position, and cooling liquid flows through oil channel, main cavity and two shunt cavities in proper order, and cooling liquid exchanges heat from cutter body inside heat transfer cutter body surface temperature, then when cooling liquid fills up main cavity, main vein and branch vein cooperate, and cooling liquid is shunted, and thus uniform effect cutter body inner wall, guarantee cooling efficiency.
