Description

Technical Field

[0001] This utility model relates to the field of spinning machines, specifically to an adaptive spinning mechanism for spinning machines. Background Technology

[0002] Spinning machines are metal plastic forming machines. An AC servo system is installed on the machine bed. This system's spinning wheel frame has two mutually perpendicular carriages, one longitudinal and one transverse. The transverse and longitudinal feeds utilize precision ball screw pairs, connected sequentially by a servo motor, a synchronous belt drive pair, and the precision ball screw pairs. Precision ball linear guides are located below the carriages. A "copying" mechanism for the mandrel's outline is located above the transverse slide of the spinning wheel frame. However, when spinning polygonal products, the mandrel used is polygonal. In this case, when using pressure rollers to spin the sheet metal, due to the polygonal characteristics, the pressure rollers will reciprocate forward and backward during spinning. This causes variations in the pressure of the pressure rollers on the sheet metal, resulting in an uneven surface on the spun product and affecting product quality.

[0003] To solve the above problems, after searching, a spinning machine with announcement number CN113967686A was found; the article proposes that the output end of the first motor (15) passes through the side wall of the U-shaped plate and is fixed to one end of the rotating shaft, and the upper side wall of the support plate is provided with an automatic adjustment mechanism to ensure that the pressure of the pressure roller is constant.

[0004] When the above-mentioned device spins and forms a workpiece using a pressure roller, the pressure roller makes hard contact with the workpiece when applying pressure. Since the thickness of different workpieces is not consistent, when the pressure roller presses on a thicker workpiece, the pressure roller assembly is subjected to a large force, which is prone to vibration and causes the surface of the pressed workpiece to be uneven. When the pressure roller presses on a thinner workpiece, the pressure roller is subjected to a smaller force, which directly affects the forming quality of the workpiece. Utility Model Content
