Abstract

The invention relates to a multi-tool-bit tool for gap groove machining. The tool is a cut-off tool and comprises tool bits and a tool rod. Each tool bit is composed of two or more slice-shaped branched tool bit bodies side by side, wherein a tool groove is formed between the adjacent branched tool bit bodies. The front angle alpha 1 of each branched tool bit body is 30 degrees, the back angle alpha 2 of each branched tool bit body ranges from 5 degrees to 10 degrees, the left drift angle alpha 11 of each branched tool bit body ranges from 92 degrees to 95 degrees, the right drift angle alpha 12 of each branched tool bit body ranges from 92 degrees to 95 degrees, the left auxiliary back angle alpha 21 of each branched tool bit body ranges from 1 degree to 3 degrees, and the right auxiliary back angle alpha 22 of each branched tool bit body ranges from 1 degree to 3 degrees. The front tool face edge of each branched tool bit body is polished into a circular-arc-shaped chip rolling groove. The multi-tool-bit tool is simple in structure and easy to manufacture. By means of the multi-tool-bit tool, the machining efficiency of parallel gap grooves in single small-batch special parts is improved. The multi-tool-bit tool is especially suitable for machining cooling fins on copper and alloy material parts or aluminum and alloy material parts or single small-batch special parts with the gap grooves, wherein the single small-batch special parts are used for other purposes.

Description

Technical field [0001] The invention belongs to the technical field of slit groove processing tools, and particularly relates to a special slit groove processing tool whose material is non-ferrous metals. Background technique [0002] In the existing production process, the design of copper and alloy material parts or aluminum and alloy material parts often requires processing heat dissipation fins or other slots on the parts. When large quantities are required, they usually use customized profiles from professional manufacturers to meet production Due to the high cost of manufacturing molds and long procurement cycle, some single-piece small batches can only adopt sporadic production mode, and some parts cannot meet the requirements of drawings due to special customized profiles. In this case, conventional processing methods mostly use single-head cutting cutters or keyway milling cutters, which are carried out on planers or milling machines according to actual conditions. Sinc...
