Embodiment Construction

[0023] The present invention adopts the frequency conversion axial automatic feeding system driven by the AC motor, see Fig. 3, Fig. 5, Fig. 6, the bar material that is detected as qualified by heating falls in the guide groove of the axial feeding device of the rolling mill, at this moment, the motor and the roll is not running, the control cylinder automatically pushes the material into the two rolls of the rolling mill in the axial direction, and installs a limit block on the lower roll mold. When the bar touches the limit block, the cylinder performs a return action. Start the roll rotation for rolling. Figure 7 shows a comparison diagram of the current and time relationship between the rolling cycle of the present invention and ordinary rolling. It can be seen that the system can not only adjust the speed of the roll as the weight of the rolled piece increases, and improve productivity, but also the motor can start rolling. , the motor does not run before the rolling is c...

Abstract

This invention relates to a wedge cross mill axial automatic feeding system of frequency-changer drive, belonging to controlling device field for plastic forming axial parts, which consisting of frequency-changing control system including switch power cabinet, frequency-changing cabinet and control cabinet; and axial feeding device including left stand (1), adjusting screw (2), socket (3), cylinder (4), right stand (5), external skirt (6), bottom board (8). The advantages of the invention are illuminated in that it can meet need of adjusting speed of mill according to rolled piece weight, improve productivity and the motor belongs to starting roll down, which can meet request of automatic, lot size and energy saving production of large-scale axial wedge cross mill.

Description

technical field [0001] The invention belongs to the field of plastic forming control and equipment for shaft parts, and in particular provides an automatic axial feeding system for a cross wedge rolling mill driven by a frequency conversion motor, which is suitable for automatic axial feeding and feeding of various shaft parts formed by cross wedge rolling. control. Background technique [0002] Cross-wedge rolling is a new forming process for shaft parts. Its principle is that two rolls with wedge-shaped dies rotate in the same direction, driving the rolled piece to rotate in the opposite direction, and roll into shaft parts with various stepped shapes. Compared with the traditional forging method to produce shaft parts, this method has the advantages of significant material saving and high production efficiency, and has been widely used in shaft parts such as automobiles, tractors, and motorcycles. [0003] At present, there are mainly two feeding methods for cross wedge ...
