Description

Technical Field

[0001] The utility model relates to the technical field of cold bending forming machines for automobile seat skeletons, and more specifically, it relates to a cold bending forming machine for automobile seat skeletons. Background Art

[0002] Under the current technical conditions, there are certain limitations in the use of cold bending forming machines for automobile seat skeletons. Specifically, since steel pipes of different models and sizes require adjustment of the specific bending positions during bending, this requires the forming equipment to have high flexibility and adjustability. However, the existing cold bending forming machines for automobile seat skeletons often cannot conveniently and quickly adjust the position of the forming sleeve. This means that when switching to producing steel pipes of different specifications, operators need to spend a lot of time and effort on equipment adjustment, which not only reduces production efficiency but also increases labor costs.

[0003] Furthermore, this technical defect has a significant impact on the practicality of the equipment. In actual production, due to the inability to quickly adjust the position of the forming sleeve to meet the bending requirements of various steel pipes, operators have to take more cumbersome steps to complete the adjustment work. This not only prolongs the production preparation time but also may lead to unstable product quality due to improper adjustment. Summary of the Utility Model
