Problems solved by technology
[0003] The tooling equipment for forming the arc (angle) of automobile sealing strips in the automobile market is a two-dimensional stretch bending equipment, because the arc of the car door is not only two-dimensional deformation, but many are three-dimensional deformation, that is, the outer water cuts in the horizontal direction and vertical Both directions are deformed, so the existing outer water cut cannot fully match the exterior decorative bright strips and door arcs during the car loading process
Therefore, the door seal obtained by the existing tooling equipment for producing the door seal cannot completely match the door, which affects the waterproof, gas-proof, dust-proof, noise reduction and other functions of the car.

Abstract
An external pressing strip bending device is characterized by comprising a rack, a downward pressing forming mechanism, a material squeezing mechanism and a tensioning mechanism; three-dimensional bending of a seal strip is decomposed into two two-dimensiaonl bending steps, the three-dimensional seal strip is obtained through bending one-time forming, and due to the fact that a metal framework isarranged in the seal strip, if no external force exits, the formed seal strip cannot deform. According to the device, the seal strip is bent and is not traditionally bent in a pulled manner, product excessive stretching and deforming of the product due to pulling and bending of the seal strip can be avoided, the original performance requirement of the seal strip is reserved better, the vehicle door radian is simulated, assembling and sealing properties of the car seal strip can be provided, and the device is convenient to operate and good in forming effect.
Description
technical field [0001] The invention relates to an external pressure bar bending device. Background technique [0002] The outer water-cut sealing strip of the automobile door (hereinafter referred to as the outer water-cut) is an auto part with both functional requirements and appearance requirements. It is installed on the outside of the door and window to realize the sealing and decoration between the door and the window glass. as functional parts. It has: waterproof, gas-proof, dust-proof, noise reduction and other functions; as a decorative part, it has the function of decorating the exposed door sheet metal along the curved arc of the door sheet metal, ensuring the overall streamline of the vehicle, and through the different appearance surfaces. The choice of material, brightness and color provides different decorative styles. [0003] The tooling equipment for forming the radian (angle) of the automobile sealing strip in the automobile market is a two-dimensional be...
