R-L longitudinal bending composite vibration special-shaped hole punching system

Abstract

The invention discloses an R-L longitudinal bending composite vibration special-shaped hole punching system. According to the R-L longitudinal bending composite vibration special-shaped hole punchingsystem, an R-L composite vibration disc and a longitudinal bending composite vibration amplitude-change pole are arranged, a plurality of vibration transducers are arranged on an outer ring of the vibration disc, and the transducers are driven by a high-frequency power source to generate vibration; the vibration energy of the multiple transducers is gathered through the R-L composite vibration disc and converted into longitudinal vibration, the longitudinal vibration amplitude is amplified through the longitudinal bending vibration amplitude-change pole, the longitudinal vibration is convertedinto longitudinal bending composite vibration, and the tool head is driven to act the composite vibration on a workpiece. Meanwhile, in combination with the feeding motion of the machine tool platform, the rapid forming of a special-shaped hole is achieved. Due to the fact that the vibration of the high-frequency energy converter can reach a very high frequency, the forming efficiency of the special-shaped hole can be effectively improved. Simultaneously, through the electromechanical control, the main device of the R-L longitudinal bending composite vibration special-shaped hole punching system can generate longitudinal bending alternating vibration rotating around the axis on the premise of no main shaft rotation, a punching tool head with a complex section shape can be normally pushedinto a workpiece in the feeding direction of a machine tool, the machining efficiency is further improved, and the machining difficulty of the complex special-shaped hole is reduced. Therefore, compared with a traditional special-shaped hole rotary punching forming device, the R-L longitudinal bending composite vibration special-shaped hole punching system has the advantages that the structure isgreatly simplified, the adaptability is higher, and the cost is further reduced.

Description

technical field [0001] The invention relates to a mechanical processing technology, in particular to a special-shaped hole forming tool system. Background technique [0002] With the development of manufacturing technology, the use and demand of various parts with special-shaped through holes and blind holes in the manufacturing industry has greatly increased. At present, the methods for processing complex special-shaped holes mainly include: slotting, rotary punching, electric discharge machining, electrolytic machining, etc. However, the slotting process is inefficient, has many burrs, and cannot realize the one-time forming of various complex special-shaped blind holes; the rotary punching process must be carried out on a machine tool with a rotating spindle, and the spindle of a non-special machine tool will be greatly damaged , when processing non-standard special-shaped holes, it is often necessary to use a specially designed linkage tool head for a specific hole, and...
