Description

Technical Field

[0001] The utility model relates to the field of frame processing cutters, in particular to a multifunctional cutter used for frames. Background Art

[0002] In the processing of an aluminum alloy frame, after cutting the groove, the side wall of the groove needs to be chamfered to avoid sharp burrs, ensure the safety of the product and avoid scratching the staff; at the same time, grooves or inner chamfers need to be set on other surfaces of the frame. Therefore, in actual processing, multiple tools are required for processing or two processes are used for processing. If multiple tools are used for processing, there is a problem of tool changing during processing, and if two processes are used, there is a problem of repositioning and moving the product, and its production efficiency is limited. Utility Model Content

[0003] The main purpose of the utility model is to provide a multifunctional tool for a frame, aiming to improve the structure of the tool so that a single tool can process two stations of the frame, thereby reducing the problem of tool change and improving processing efficiency.

[0004] To achieve the above-mentioned purpose, the utility model proposes a multifunctional tool for a frame, comprising a rod body, a first blade portion arranged at the bottom end of the rod body, and a second blade portion arranged above the first blade portion, a transition portion with a reduced diameter is provided between the first blade portion and the second blade portion, the first blade portion is used for processing fillets or punching, the second blade portion is gradually reduced in diameter from the rod body toward the transition portion, and the second blade portion is used for processing a second chamfer 300.

[0005] In the actual design, the first cutting edge and the second cutting edge are arranged on the tool bar, and the transition portion is recessed between the rod body and the first cutting edge, so that interference caused by the processing of the first cutting edge and the second cutting edge respectively can be avoided, and the processing stability of the two cutting edges is ensured. The first cutting edge and the second cutting edge are arranged on the same tool, and in the actual processing, the steps of tool changing can be reduced, and the processing efficiency and processing stability can be effectively improved;

[0006] This tool is mainly used in PIS dual-spindle CNC machines. The structural processing of the frame product generally requires 12 to 14 tools to complete. By improving some tools, the number can be reduced to 8 to 9 to complete the processing of the entire frame structure (including the stamping part at the bottom of the first blade, the first blade angle, and the second blade); cost saving evaluation: based on a processing cost of 0.8 yuan per minute, each piece can save: 2 yuan (about 3 minutes (including tool change, cutting, position calibration)), based on an order of 100,000 pieces, the total cost savings: 160,000 yuan.
