Description

Technical Field

[0001] The utility model relates to the technical field of expansion machines, in particular to a high-efficiency CNC expansion machine. Background Art

[0002] In the process of coil processing, a CNC expansion machine is usually used to expand the semi-finished coils.

[0003] The CNC expansion machine described in publication number CN214626738U is provided with a support arm, a drive motor, a screw and a lower card plate. The outer side of the semi-finished coil is placed on the lower card plate. The cylinder is turned on to push the lower card plate up, and the semi-finished coil is clamped and fixed by the upper card plate. The drive motor is turned on again to drive the screw rod to rotate, and the internal threaded sleeve moves back to back, thereby pushing the support arm to move back to expand the coil. The anti-slip pads on one side of the lower card plate and the upper card plate can protect the semi-finished coil and prevent the coil surface from being worn when the lower card plate and the upper card plate are clamped to it. However, the existing technology still has defects:

Therefore, it can only expand coils of fixed sizes, and cannot adjust the position of the expansion according to coils of different lengths. The scope of application is relatively small.

[0005] 2. The existing technology requires workers to manually put each set of coils between the upper and lower clamping plates and then expand them, which is time-consuming, labor-intensive and inefficient. Utility Model Content
