Abstract：Pipe bending machine automatic feeding system is mainly in order to realize the fully automatic machine tool manufacturing process, and used the integrated processing technology, is suitable for the production line of feeding. Obviously save labor force, the production rhythm, stable product quality and reliability are improved obviously, in modern manufacturing industry, the requirement of high precision, stable quality, batch processing speed, using artificial way to work in manufacturing level of processing is very difficult to get promoted, using industrial robots can reduce rejection rate and the product cost, improve the utilization rate of the machine tool and reduce the workers wrong operation risk defective parts, etc., save labor costs. The benefits are also obvious, such as reducing artificial dosage, reducing the loss of machine tools and improving the competitiveness of the enterprise.

The content of this design is to design a set of pipe bender, automatic feeding system for pipe bending machine for automatic feeding, on the basis of the existing pipe bending machine, use the feeding machine for pipe bender automatic feeding, feeding machine with three degrees of freedom model group handling module, the module will finish in process pipe bending processing artifacts into the container. In this paper, we design the material parts, parts, three degrees of freedom and control system. The 3d model of the hopper and its geometric dimensions, the cylinder diameter and the itinerary of the cylinder are designed. The material parts of the material are designed in three dimensions. The three degrees of freedom of the moving module are designed for the grip hand and the linear module of each axis according to the need. The control part of the design is the pneumatic control system, the linear module control system, and the control of the whole working flow of the equipment. Also, a brief introduction to touch screen control.

The automatic feeding system of the bending machine has improved the production efficiency of the pipe bender, and reduced the labor quantity of the workers. And the whole PLC control, the touch screen machine interface, realized the automation production.
