Apparatus for blanking and processing profile notches of rubber sealing strip

Abstract

This invention discloses a device for blanking and processing rubber sealed strip-type slot; essentially composed by counter die part, upper die part and oblique cutting part. It is characterized in adopting work piece outline of the counter die's surface and its end face's lateral positioning machine to actualize rapid and accurate position for work piece's feeding; the outline of pressing plate and counter die's surface individually furring with upper and lower surfaces of sealing strip to prevent its surface from destroying; pressing device of upper die mainly comprising adjusting screw rod, packing force adjusting nut, spring block, spring guide and connecting block, and being able to adjusting packing force of work piece; using inclined punching guiding block of the oblique cutting part to avoid interference of upper die to oblique punching tool. The invention has the advantages of simple structure, high processing quality and efficiency.

Description

technical field [0001] The invention relates to a rubber sealing strip surface notch punching processing device, which can be used for positioning and compacting the rubber sealing strip profile notch punching processing, and can realize oblique punching processing of the edge notch of an inclined surface, belonging to non-metallic materials The field of mechanical processing technology. Background technique [0002] The sealing strip is one of the important parts of the car, and its sealing performance directly affects the safety and ride comfort of the car, and it is also one of the important decorative parts on the car. After the sealing strip is formed, it needs to be further machined to meet the assembly and connection requirements. As the final process of sealing strip production, the quality of machining is directly related to the final quality of the finished sealing strip, which in turn affects the sealing performance and aesthetics of automobile doors and windows,...

AI Technical Summary

Problems solved by technology

Analyzing the design of the device, it is not difficult to find the following disadvantages: To ensure that the sealing strip is pressed tightly, the sealing strip should be under pressure in the clamp body, which brings great difficulties to the loading of the workpiece and greatly affects the processing. efficiency improvement

At present, there is no relevant literature that provides a suitable pressing force solution for the punching process of the sealing strip, and there is no report on the device used to realize the punching process on the edge of the inclined surface of the sealing strip.
