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 a Figure 4 The punching process of the profile cutout of the sealing strip shown, the plane where the cutout is located is at a certain angle to the horizontal plane.

[0031] figure 1 It is a three-dimensional structural diagram of the rubber sealing strip surface notch punching processing device of the present invention. Such as figure 1 As shown, the device consists of a lower mold part, an upper mold 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 p...

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,...
