Abstract

The invention discloses a vehicle sealing strip skeleton, and relates to the field of automobile sealing parts. The vehicle sealing strip skeleton comprises a stretching belt, a plurality of bone pieces are arranged symmetrically on the two sides of the stretching belt in an arrayed manner, gaps are arranged between the adjacent bone pieces, the stretching belt is provided with a plurality of middle holes in the length direction, and side holes are formed in the two sides of the part, between every two adjacent middle holes, of the stretching belt. In order to solve the problems that in the prior art, the utilization rate of raw materials is low, the production efficiency is insufficient and the production cost is high, the two sides of the stretching belt are provided with bone strips, the middle holes, the side holes and the gaps are formed through the stretching belt having the stretching effect, waste of the raw materials can be greatly reduced, and the production efficiency of thevehicle sealing strip skeleton can be improved.

Description

technical field [0001] The invention relates to the field of automobile seals, more specifically, it relates to a skeleton of a weather strip for automobiles and a processing technology thereof. Background technique [0002] The sealing strip skeleton is often used in cars and trunks to improve the sealing of the joints of cars and trunks. [0003] For the existing sealing strips for automobiles, most of them are processed by punching raw steel strips, and the processed finished products have a tensile strength of about 400Mpa. [0004] The existing sealing strip products have low raw material utilization rate, insufficient production efficiency, and high production cost, which cannot meet the new national requirements for energy saving, environmental protection and light weight of passenger vehicles. Contents of the invention [0005] In view of the above-mentioned problems in the prior art, the purpose of the present invention is to provide a vehicle sealing strip skele...
