In the early stages of the development of automatic winding machine, the mechanical structure and ordinary winding machine compared to not much change, but in the cable agencies, over wheel and tension devices and operation to make some changes. With the development of numerical control technology, taking into account its control methods and the use of features, only on the automatic winding machine productivity, precision and life of the proposed higher requirements.
The main body of the winding machine has the following characteristics:
1, as a result of the use of high-performance stepless spindle and stepper drive system, the winding machine's extreme transmission structure is greatly simplified, the transmission is also greatly reduced;
2, in order to adapt to continuous automated processing and improve processing productivity, winding machine mechanical structure has a high static, dynamic stiffness and damping accuracy, and high wear resistance,
3, in order to reduce friction, eliminate transmission gap and get higher winding accuracy, more efficient use of the transmission components, such as ball screw and rolling guide, anti-backlash gear drive;
4, in order to improve working conditions, reduce the auxiliary time, improve operability, improve labor productivity, the use of a quick rod loading and unloading, pneumatic thimble and other auxiliary devices.
So to design and develop a winding machine as a winding machine production units need to consider the points are those? Mainly have the following points:
(A) of the higher body static and dynamic stiffness
Winding machine is in accordance with the NC programming or manual input data provided by the instructions of the automatic winding. As the mechanical structure of the geometric accuracy and deformation of the positioning error in the processing can not be artificially adjusted and compensated, it must be the mechanical parts of the elastic deformation generated to a minimum to ensure the required accuracy. In recent years in the winding machine on the use of steel welded structure of the bed, columns, beams and workstations. Seal casting sand is also conducive to vibration attenuation, to improve the vibration resistance also has good results.
(B) reduce the friction between the movement and eliminate the transmission gap
Winding machine cable displacement mechanism is to ensure the accuracy of equipment, usually also requires a high speed movement. In order for the cable spindles to respond accurately to the commands of the CNC, it is necessary to take appropriate measures. At present, there are obvious differences in friction damping characteristics between sliding guide, rolling guide and hydrostatic guide. The same effect can be achieved by using a ball screw instead of a slide screw in the feed system. At present, winding machine almost without exception, the use of ball screw drive.
(C) to improve the life of the machine tool and precision retention
In order to improve the life and accuracy of the winding machine to maintain, in the design of parts should be fully considered the wear resistance, especially the motor, stepper, spindle components affect the accuracy of the main parts of the wear resistance. In the course of use, should ensure that all parts of a good lubrication.
(4) to reduce the auxiliary time and improve operational performance
To further improve the productivity of the apparatus, it is necessary to take the time of assisting in maximizing the compression. There are already a lot of winding machine with a multi-spindle, multi-row wire frame, etc., in order to improve winding efficiency.
The above points hope that the majority of users of the winding machine on the characteristics of this equipment have an understanding of the pros and cons of evaluation equipment at the time of purchase help.
