Sealing strip breaking machine with double steel belt door strip

Abstract

The invention relates to the technical field of manufacturing of automobile sealing strip production equipment, in particular to a breaking machine for a door strip type sealing rubber strip containing double reinforced steel belts. Fatigue sets are arranged on the upper side in a breaking box on a rack. Each fatigue set internally comprises an upper column of driving wheels and a lower column of driving wheels, wherein the upper column of driving wheels and the lower column of adjacent driving wheels are arranged in a staggered manner. A breaking set is arranged on the lower side in the breaking box and comprises an upper column of breaking wheels and a lower column of breaking wheels, wherein the upper column of breaking wheels and the lower column of adjacent breaking wheels are arranged in a staggered manner. A transition set is arranged on the position, located on one side of the breaking set, of the lower side in the breaking box and comprises a transition wheel, an upper column of driving wheels and a lower column of driving wheels. At least one driving wheel is arranged in each column. The outer diameter surface of the driving wheels and the outer diameter surface of the transition wheel are cylindrical. Driving breaking wheels are sheet-shaped or cake-shaped breaking wheels. Each driven breaking wheel is characterized in that an annular V-shaped groove or a rectangular groove or a polygonal groove is formed in the outer cylindrical face. The breaking machine for the door strip type sealing rubber strip containing the double reinforced steel belts has the beneficial effects that the steel belts in the sealing strip can be stably broken, the breaking effect is extremely good, and stability is high.

Description

technical field [0001] The invention relates to the technical field of manufacturing equipment for automobile sealing strips, in particular to a breaking machine for sealing strips containing double-bar steel belt door strips. Background technique [0002] Rubber sealing strip is a sealing strip made of rubber. It is widely used in the fields of automobile doors and windows, and plays the role of dustproof, sound insulation, shock absorption and sealing. This kind of tooling is mainly suitable for the production of door strips, door The strip-type automotive weather strip is installed around the door sheet metal, that is, it is stuck on the sheet metal. The purpose of installing a steel strip in the automobile sealing strip is to enhance the strength of the sealing strip, and to enhance the clamping force and pull-out force of the assembly of the sealing strip, that is, the assembly on the sheet metal. The purpose of breaking is to make the inner steel belt of the sealing s...

AI Technical Summary

Problems solved by technology

The primary defect of this kind of breaking machine is that the equipment is too long and the floor area is too large, which makes it impossible to place in a small site. The too long equipment also leads to the wasted length of the ends of the sealing strip during the breaking process. For For the manufacturer, the economic cost is relatively large, and the equipment is too long, which makes it too long for the operator to wind the sealing strip on the breaking wheel in sequence; in addition, the breaking effect of this breaking machine is poor, due to fatigue and breaking If the rotating speed of the group is set constant, then in the process of transmission, the cooperation and breaking effect of the fatigue group and the interrupting group is relatively poor, which often makes the length of the interrupted steel belt in the sealing strip different, and the length of each steel belt The length is also relatively long, resulting in poor use of the sealing strip
