AI Technical Summary
The folded rotary safety columns of existing hydraulic presses are laborious due to friction of the bore shaft, and the dimensional uncertainty caused by paint rust prevention causes the safety columns to tilt and shake.
Two sets of deep groove ball bearings are added to the rotating shaft, which reduces friction through these bearings, makes the safety column more lightweight when used, and solves the problem of safety column tilt by reducing machining clearance.
The light use of the safety column is achieved, avoiding tilt and shaking due to the gap, making the overall appearance more beautiful.

Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of hydraulic press safety columns, in particular to a rotary folding bearing safety column suitable for a frame type hydraulic press. Background Art
[0002] At present, the conventional foldable rotating safety column of the hydraulic press is used by matching the hole and the shaft. Friction is generated when the hole and the shaft rotate. Since the overall weight is relatively heavy, the friction generated makes it more difficult for people to push the safety column. In addition, since it is necessary to prevent the shaft from rusting and causing the whole to get stuck, the shaft needs to be painted for rust prevention. The thickness of the paint makes it difficult to control the matching size between the hole and the shaft. Sometimes, if the gap is too small, it will not fit in. If the gap is too large, the safety column will be in a tilted state, and the whole will shake when used. In view of the above defects, the utility model provides a rotating foldable bearing safety column suitable for a frame type hydraulic press. By adding two sets of deep groove ball bearings in the rotating shaft, the foldable rotating safety column is lighter to use. At the same time, the tilted state of the safety column caused by the gap generated during processing is solved, making the overall appearance more beautiful. Utility Model Content
