Description

Technical Field

[0001] The utility model relates to the field of design and manufacture of automobile parts processing equipment, and more specifically, it relates to an external pressure strip anti-deformation skeleton punching tool. Background Art

[0002] The outer molding is one of the important parts for sealing automobile doors and windows, and is also one of the important decorative parts on the automobile. In the actual production of the outer molding, it is usually necessary to process a cut at the end of its frame after the outer molding is formed to meet the requirements of assembly and connection when the outer molding is used.

[0003] At present, the processing of skeleton incisions is generally formed by punching and cutting tools, which has many advantages such as simple operation, high efficiency, suitability for mass production and easy automation. In order to ensure stability during punching, a limiting device is usually required to limit the position of the skeleton. However, this will require pre-adjusting the position of the skeleton each time the punching and cutting process is performed, and the punching tool can only be lowered for punching and cutting after the limiting device completes the position restriction of the skeleton. After the punching and cutting is completed, the punching tool needs to be retracted first, and then the limiting device is retracted and the skeleton that has been punched and cut is taken out before subsequent punching and cutting work can be carried out. This leads to low efficiency of the punching and cutting work. Utility Model Content
