Terminal cutting machine - drive system
Abstract:
In this paper,Is developed in this paper, terminal cutting machine, cutting machine transmission system for the terminal bending system. Including bending and cutting terminal connection between small sheet. Need to complete the design of the contents are: the terminal of the cutting machine transmission system, bending, cutting work station.
 The equipment of terminal cutting is a integration of electrical automation equipment automatic including feeding, bending, CARRY cutting and cutting into seven terminals machine. It is mainly Compose of feeding and cutting machine, power and electronic control components. The author design the motion control part of cutting machine and design the structural. The motion Control design use pneumatic drive and the rational timing diagram; Structural design need to consider feeding mechanical structure, length of feeding control, cutting tool design, achieve shear mechanical structure design and so on. The coordination and synchronization of the cutting machine feeding, bending and cutting is the core technology, The remaining part require synchronization, ultimately leading to the various parts work together. In structure design, analysis the principle of feed mechanism used in the allocation of materials and the feeding STOP position on the use of block allocation spacing screw. Cutting Tool structure should be reasonable and should have sufficient strength and stiffness.
After the different sports scheme and design of components of qualitative analysis and comparison to determine the terminal of the cutting machine drive system design scheme is: cooperate with sensor and PLC controller in mechanical transmission terminal of high-speed machining. Coming from motor drive power through coupling, bearing is passed to the CAM, again by CAM driven roller bending and cutting tool, the induction bending work station by sensors work process, and outgoing signal to controller, cutter feeding and cutting. Compared with the present domestic same type machining center, has a compact structure, small space dimension, and high production efficiency etc. 端子裁切机传动机构设计+CAD图纸:http://www.751com.cn/jixie/lunwen_13369.html
