According to the utility model, different cutting edges are arranged according to rubber materials and metal materials, cutting notch is tidy, less bending or damage and no punching and cutting deformation occur so that the composite punching and cutting machine is suitable for punching and cutting various seal strips having metal materials.
Description
Technical field
The utility model relates to a kind of bright special-shaped sealing strip does not have the compound bicker of distortion.
Background technology
Bright special-shaped sealing strip is composited by rubber and bright stainless steel band and aluminium skeleton.Original sealing strip end angle adopts the saw blade cutting, produces a large amount of saw iron filings, and the burr that very easily scratch surface, and end face produces need be polished, and soft flocks is difficult for cleaning out.Polishing back stainless steel end face easily gets rusty.
The die-cut edge structure of common die cutting device is single, or too frivolous, sharp, loses easily when running into bright stainless steel band and aluminium skeleton; Or too thick and heavy, blunt, when cutting elastomeric material, otch is uneven, is not suitable for die-cut bright special-shaped sealing strip.
The utility model content
The technical problems to be solved in the utility model is how to fill up the above-mentioned blank of prior art, provides a kind of bright special-shaped sealing strip not have the compound bicker of distortion.
For solving the problems of the technologies described above, this bright special-shaped sealing strip do not have the compound bicker of distortion, comprise hydraulic cylinder, die-cut cutter and counterdie, wherein die-cut cutter is fixed on the piston-rod lower end of hydraulic cylinder, counterdie is arranged on die-cut cutter below, sealing strip to be cut contains metallic framework, is placed between counterdie and the die-cut cutter.Described die-cut cutter lower end cutting edge is compound cutting edge, and this compound cutting edge comprises die-cut cutting edge of metal and the die-cut cutting edge of rubber, and wherein the die-cut cutting edge thickness of metal is greater than the die-cut cutting edge thickness of rubber, and the metallic framework in the sealing strip to be cut.
So design, when running into hard metallic framework, die-cut cutter is difficult for losing; When cutting comparatively soft material such as rubber or plastics, otch is neat.
After the shape of the die-cut cutter of appropriate change, also can process arc-shaped sections, this is that saw blade cutting institute is inaccessible.
As optimization, described metallic framework comprises bright stainless steel band and aluminium skeleton.
As optimization, described sealing strip to be cut both sides are respectively equipped with the slip clamp of band back-moving spring, the inboard opposite face of two slip clamps and sealing strip shape to be cut adapt, its lateral wall is that introversion is domatic, described die-cut cutter both sides are respectively equipped with briquetting, this briquetting is fixed on the hydraulic cylinder piston rod lower end by the lead of band support spring, and the briquetting inboard is provided with and the corresponding guide ramp of lateral wall of the clamp that slides, and cooperates with the slip clamp.
So design, during use, when hydraulic cylinder piston rod pressed down, briquetting inwardly squeezed two slip clamps earlier and pushes away, and sealing strip to be cut is clamped from both sides, and die-cut then cutter just contacts with sealing strip to be cut.The otch skeleton, not yielding more.
As optimization, described counterdie is 40～50 ° of acute angles over against the angle of cutting edge on cross section of bright stainless steel band of sealing strip to be cut.So design, good cutting effect.
As optimization, described die-cut cutter the place ahead also is provided with safe light curtain.So design can prevent effectively that foreign matter enters die-cut zone in the die-cut process, causes danger.Safe light curtain and using method thereof are prior art, slightly.
The utility model adopts and at elastomeric material and metal material different cutting edges to be set, and it is neat to have an otch, is difficult for losing, not having the advantage of die-cut distortion.Be fit to the die-cut various sealing strips that contain metal material.
