Description

Technical Field

[0001] The utility model relates to the technical field of swivel chair support seat processing, and more specifically, to a punching device for swivel chair support seat processing. Background Art

[0002] The swivel chair support seat is an important part of the swivel chair. It is located at the bottom of the chair, bears the weight of the entire chair, and provides stable support. At the same time, the support seat also contains a rotation mechanism, which allows the swivel chair to rotate freely, making it convenient for users to move and turn in different directions. In the processing of the swivel chair support seat, a stamping device is used. The stamping device uses a mold for stamping, which can ensure that the size and shape of each swivel chair support seat meet the design requirements and ensure the accuracy and quality of the swivel chair support seat.

[0003] In the existing technology, the document with the announcement number CN219746120U specifically discloses a highly efficient stamping equipment for processing the support seat of a swivel chair. The device in the document uses the coordinated use of components such as a robotic arm, a support seat stamping machine and a support seat material rack. The robotic arm is used to feed the support seat to be processed of the support seat material rack into the support seat feeding rack, and the support seat is transferred in the support seat stamping machine through the robotic arm to quickly complete the processing of the support seat. The device in the document improves the processing efficiency of the support seat to a certain extent through the robotic arm, but after the robotic arm clamps the support seat, the support seat needs to be placed on the material rack. After stamping, the processed support seat needs to be taken out, and then the support seat needs to be re-clamped for processing, which to a certain extent leads to a longer idle period of the stamping machine. For this reason, we propose a stamping device for processing the support seat of a swivel chair. Utility Model Content
