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.

Embodiment Construction

[0029] Embodiments of the present invention will be described in further detail below in conjunction with the accompanying drawings.

[0030] A typical implementation of the present invention is shown in the accompanying drawings, which is used to realize the die-cutting of the profile cutout of a sealing strip as shown in FIG. 4 , where the plane where the cutout is located is at a certain angle to the horizontal plane.

[0031] Fig. 1 is a three-dimensional structure diagram of the device for punching and punching the rubber sealing strip profile of the present invention. As shown in Figure 1, the device consists of a lower die part, an upper die part and an oblique punching part. The lower mold part is mainly composed of a lower module 13 and a lateral positioning mechanism; the upper mold part is mainly composed of a pressing plate 11, a tool clamping module 18, a guide post 12 and a pressing mechanism.

[0032] The lower module 13 is installed on the working platform 14 ...

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,...
