Mirror surface rolling tool with internal cooling lubricating function

Abstract

The invention relates to a mirror surface rolling tool with internal cooling lubricating function (also known as a rolling cutter). A position of the rolling tool close to a clamping position is provided with an oil-taking device; the interior of the rolling tool is provided with a flow passage connected with the oil-taking device; an oil outlet of the internal flow passage is arranged on the surface of a mandrel of the rolling tool; the diametrical connection between the oil-taking device and the rolling tool is movably sealing connection so that the oil-taking device does not rotate with the rolling tool. When in work, the rolling tool does rotary movement (or workpieces do rotatory movement) and the workpieces are still (or the rolling tool is still); a lubricating oil or cooling fluid oil delivery pipe is connected with the oil-taking device of the tool; the lubricating oil or cooling fluid reaches the top of a rolling needle of the rolling tool by the internal flow passage and the oil outlet, outflows from the periphery of the rolling needle, and then contacts the surface of the workpieces, thus achieving the effects of lubrication and cooling; the lubricating oil or cooling fluid can also dash out impurities to achieve the purpose of washing. The mirror surface rolling tool can be used on equipments such as lathes, drill presses, milling machines, machining centers and the like, and is widely applied to mechanical workout industries.

Description

technical field [0001] The invention relates to the field of cold machining of metal parts without cutting. In particular, mirror rolling tools (or mirror rolling tools) that can process the surface of metal parts to a mirror surface precision (Ra≤0.1μm) and have internal cooling and lubrication functions. Background technique [0002] At present, in the actual processing of rolling tools that can process mirror surface precision, oil pumps are used on the equipment or operators use tools to pour or smear lubricating oil or coolant on the rolling tools and workpieces from the outside during the processing process. In actual processing, when the rolling tool is in contact with the workpiece, a sealing structure is formed, and oil or coolant cannot enter the processing surface for real-time cooling and lubrication; and when the tool or workpiece is rotated, the centrifugal force will make the The oil or coolant splashes out, causing the oil or coolant to lose its lubricating ...

AI Technical Summary

Problems solved by technology

It is necessary to increase the flow rate of oil or coolant through repeated application or increase the power of the oil pump, which will cause a lot of inconvenience to production. The oil or coolant will cover the actual processing part, so that the operator cannot directly see the processing part of the workpiece Changes in shape and position will affect the processing quality and the improvement of production efficiency, and the amount of oil or coolant used will also double; at the same time, when cleaning and maintaining the rolling tool, the tool must be disassembled or even disassembled to achieve internal cleaning. Purpose

After document retrieval, there is no mirror rolling tool with internal cooling and lubrication function
