Description

Technical Field

[0001] The invention relates to the field of automobile sealing strip production equipment, in particular to a punching and buckle installation equipment for automobile sealing strips. Background Art

[0002] Sealing strips are one of the most important parts of automobiles, and are widely used in doors, windows, car bodies and many other parts. They play an extremely important role in sound insulation, dustproofing, and waterproofing. In the processing of sealing strips, it is often necessary to punch holes in the sealing strips, and then install connecting buckles at the punched positions before cutting. However, in the prior art, because the conveying device cannot fix the sealing strips well, the cutting length of the sealing strips is low in precision, resulting in different lengths. Currently, the installation of buckles on sealing strips is mainly done manually by production personnel, and the punching operation is performed separately from the buckle installation operation. As a result, the labor intensity of the staff is high and the production efficiency is relatively low, which limits the degree of automation of punching and buckle installation.

[0003] Therefore, in view of the deficiencies of the prior art, the present invention provides a punching and buckling device for an automobile sealing strip to solve the deficiencies of the prior art. Summary of the invention

[0013] A further preferred solution of the present invention is that a plurality of slide rails with sliders are arranged below the track.

[0014] A further preferred embodiment of the present invention is that the rear section of the track is provided with a cutting assembly.

[0024] The cylinder is tilted and has a waist-shaped slot at the end. The middle cylinder 7 is provided with a snap-in point located in the slot. When the cylinder is working, it will push the middle cylinder 7 to rotate around the central axis through the snap-in point.

[0025] The two screw rods 8 are coaxial with the middle cylinder 7. It is ensured that the screw rods 8 rotate around the central axis and can rotate and move with the buckle.

[0026] A rolling assembly 12 is provided in front of the track 1. The rolling assembly 12 includes rollers arranged in two rows, and the sealing strip 10 passes between the two rows of rollers. Because the sealing strip 10 is placed there in a roll, the rolling assembly 12 is used to regularize the sealing strip 10 so that the sealing strip 10 is straight.

[0027] A punching assembly 13 is provided at the rear side of the track 1. The punching assembly 13 is located at the front end of the track 1. The punching assembly 13 is installed on the ball screw. When the ball screw is working, the punching assembly 13 moves along its axial direction. When the punching assembly 13 is working, a through hole can be punched on the sealing strip 10. The punching assembly 13 of the present invention will keep moving synchronously with the sealing strip 10 and punch holes when the sealing strip 10 moves forward.
