Abstract

The invention provides a production method of an embossing device for sealing strips. A slider is arranged on a support plate, a large steering shaft is arranged at the lower end of the slider, and the embossing device is arranged under the large steering shaft; a connecting block is arranged under the large steering shaft, first connecting rods are arranged under the connecting block, a second connecting rod is arranged at the tail end of each first connecting rod, an embossing roller is arranged at the tail end of each second connecting rod, and a notched panel is further arranged in the middle of the connecting block; the first connecting rods and the second connecting rods are arranged in two sets and are symmetric to the center of the notched panel, and a connecting shaft is arrangedbetween each first connecting rod and each second connecting rod. The embossing device is simple in structural connection, the sealing strips are embossed upon being extruded out, processing steps andprocessing time are reduced, and working efficiency is improved; by the design of small steering shafts at upper ends of the corresponding embossing rollers, the embossing rollers are adjusted in position and direction rapidly according to shapes of the sealing strips, and practicability and flexibility are improved.

Description

technical field

[0001] The invention relates to a preparation method of an embossing device for a sealing strip. Background technique

[0002] The automobile door frame sealing strip is a sealing strip inlaid on the seam of the side panel of the door frame. The door frame sealing strip must not only ensure airtightness, but also bear the impact force when the door is closed. Therefore, it must have both elasticity and toughness. It is mainly composed of two parts: a dense rubber matrix and a sponge rubber foam tube. The dense rubber contains a metal skeleton, which plays the role of strengthening, shaping and fixing. The sponge foam tube is soft and elastic, and plays the role of deformation under pressure and rebound after pressure relief. In addition, the lip part of some sealing strips will be compounded with colored rubber or pasted with fabric for decoration. The lip part of the sealing strip generally needs to be pressed with the same pattern as the interior decorat...
