Description

Technical Field

[0001] The utility model relates to the technical field of universal wheel manufacturing, in particular to a universal wheel bracket stamping mechanism. Background Art

[0002] Universal wheels are movable casters, and the bracket on which the casters are installed can rotate 360 ​​degrees horizontally under dynamic or static loads. Universal wheels are widely used in various fields, and the structure of universal wheels also needs to be adjusted according to different usage scenarios.

[0003] Most universal wheel brackets are stamped products. A bracket panel of a suitable shape and size is cut from a steel plate according to the shape of the bracket when it is unfolded. The bracket panel is then placed on the workbench below the punching machine. A forming groove is provided in the stamping base on the workbench. The punching machine uses a punch to press the bracket panel into the forming groove, thereby punching out a qualified universal wheel bracket. However, during the current stamping operation, workers need to manually place the bracket panel on the stamping base, and after the punch is used for stamping, the formed universal wheel bracket is removed and a new bracket panel is placed. This one-place-one-take working mode is inefficient, and workers are prone to stamping injuries when taking the bracket under the punch, which poses a great safety hazard. Utility Model Content

[0009] On the basis of the above solution and as a preferred solution of the above solution: a driving motor for driving the turntable to rotate is provided under the turntable.

[0010] On the basis of the above scheme and as a preferred scheme of the above scheme: the two punches on the punching machine run synchronously and are located directly above the two punching bases on the same side.

[0011] When in use, a bracket panel is placed on each stamping base on the turntable, the roller mounting holes on both sides of the bracket panel are sleeved on the positioning pins, and the bracket panel is placed above the movable seat; then the turntable starts to rotate, and one side is rotated into the stamping area of ​​the stamping machine, and the two punches are positioned opposite to the two stamping bases on this side. Then the stamping machine works, and the two punches are pressed down synchronously. The punches press the bracket panel into the forming groove, and the bracket panel is punched into a universal wheel bracket. Then the punch leaves the universal wheel bracket, and the movable seat is reset upward under the action of the spring to eject the formed universal wheel bracket.

[0012] When the universal wheel bracket on one side is formed, the turntable continues to rotate, allowing the two stamping bases on the next side to enter the stamping area and repeat the above stamping work; at the same time, after the previously stamped universal wheel bracket is moved out of the stamping area, the staff can remove the stamped universal wheel bracket and put in a new bracket panel, waiting to enter the stamping area next time, and so on, to complete the stamping operation of all bracket panels.

[0013] Compared with the prior art, the beneficial effects of the utility model are: a rotatable polygonal turntable is used to switch the bracket panel entering the stamping area, and the staff takes the stamped bracket and places the un-stamped bracket panel outside the stamping area to avoid stamping injuries; and during the taking and placing process, the stamping machine does not stop, and the stamping efficiency is high; two punches are provided on the stamping machine, which can stamp two universal wheel brackets at the same time, greatly improving the production efficiency.
