Embodiment Construction

[0040] In order to make the technical means, creative features, goals and effects achieved by the present invention easy to understand, the present invention will be further described below in conjunction with specific illustrations. It should be noted that, in the case of no conflict, the embodiments in the present application and the features in the embodiments can be combined with each other.

[0041] Such as Figure 1 to Figure 11 As shown, a manufacturing process of automobile door and window sealing rubber strips uses a burr removal device, which includes a bottom plate 1, a limit device 2, a traction device 3, a burr removal device 4 and two linkage clamping devices 5. Using the above-mentioned burr removal equipment, the manufacturing process of the sealing rubber strip for automobile doors and windows is as follows:

[0042] S1. Molding: heat-melt particles are sequentially extruded, drawn, cooled and shaped to obtain a molded sealing strip;

[0043]S2. Trimming and...

Abstract

The invention provides a manufacturing process of an automobile door and window sealing rubber strip. A bottom plate, a limiting device, a traction device, a burr removing device and two linkage clamping devices are matched to complete operation; and the manufacturing process can solve the problems that due to the fact that a material of the sealing strip is soft, the middle of the sealing strip is still in a suspended state in the process of tensioning the two ends of the sealing strip for burr removing, when the sealing strip is in contact with a brush, the sealing strip is easily deformed due to extrusion, and the brush is difficult to effectively remove burrs of the deformed sealing strip.

Description

technical field [0001] The invention relates to the technical field of manufacturing sealing rubber strips, in particular to a manufacturing process for automobile door and window sealing rubber strips. Background technique [0002] The sealing strip is a product that seals something so that it is not easy to open, and has the functions of shock absorption, waterproof, sound insulation, heat insulation, dustproof, and fixing. It can be used for automobile doors and windows to prevent water seepage, etc. In the manufacturing process of the sealing strip, after its extrusion molding, its surface needs to be trimmed, and there are still burrs on the surface of the trimmed sealing strip. To solve the problem of burrs, people usually tighten the sealing strip, and then use a special Burr brushes are used to remove burrs, but this method often encounters some problems: [0003] Due to the soft material of the sealing strip, the middle part of the sealing strip is still in a suspe...
