钢筋切断机设计
摘 要：为实现钢筋切割工作的现代化，国内外研制了不少钢筋切割机。然而在钢筋切割机系列中，对切割Ф40钢筋的切割还是处于一个较为薄弱环节，为了降低切割Ф40钢筋的难度，提高工作效率。本设计采用电动机经一级V带传动和二级齿轮传动减速后,带动曲轴旋转,曲轴推动连杆使滑块和动刀片在机座的滑道中作往复直线运动,使活动刀片和固定刀片相错而切割钢筋。

Design of The Steel Bar Cutting Mac Machine
Abstract: To realize the modernization of the steel bar cutting work, at home and abroad people had developed a lot of steel bar cutting machine. In steel bar cutting machine series, however, of cutting Ф 40 reinforced research is still in the weak link, in order to decrease the difficulty of cutting Ф 40 reinforcement to improve work efficiency. This design uses the motor by a V belt transmission and secondary gear transmission to slowdown. Then, it drives the crank rotate, The crank connected to slide block and moving blades in the slippery way make the back and forth straight line sport, makes the moving blades and the fixed blade shear and cut steel.
