Four core advantages of automatic spinning machine

Generally speaking, light-duty automatic spinning machines (including ordinary spinning machines and powerful spinning machines) have similar structural advantages to ordinary lathes. However, in order to meet the requirements of the above spinning process, large-scale spinning machines, especially large-scale powerful automatic spinning machines, usually have the following 11 core advantages.

  1. The bed, main shaft and transmission system, rotary wheel frame, tailstock and other parts of the automatic spinning machine should have sufficient rigidity, and also have a relatively bulky worktable, thicker guide rails, and thick-walled load-bearing brackets and box etc.
  2. The horizontal and vertical feeding mechanisms of the rotary wheel frame are mostly driven by hydraulic transmission or combined mechanical and hydraulic drive to generate sufficient spinning force and balance the stepless speed regulation to meet the process requirements.
  3. Ordinary automatic spinning machines mostly use one spinning wheel but multiple auxiliary forming wheels (flanging wheels, curling wheels, etc.). The number of rotary wheels or rotary wheel frames of the powerful automatic spinning machine is mostly 2 to 3 (the general type is 2 to 3 cylindrical part spinning machines) and is symmetrically arranged relative to the axis of the main shaft to balance the spinning When the radial force reduces the bending deflection, yaw and vibration of the spindle and the core mold, it provides a prerequisite for improving the accuracy of the spinning part. This accordingly requires the rotary wheel to have a high lateral (such as a special spinning machine for cylindrical parts) or longitudinal (such as a general-purpose automatic spinning machine) synchronous feed accuracy. However, a rotary wheel is used for light and powerful automatic spinning machines.
  4. The main shaft has sufficient transmission torque and power. According to specific process requirements, it can meet constant torque or constant power regulation. In addition, it is better to make the spindle speed and the longitudinal feed speed of the rotary wheel to be stepless speed regulation, on the one hand, it can meet the arbitrary selection requirements of the spinning process; Possibility of constant feed.
