Description

A kind of superelevation scraper plate blanking die

Technical field

The present invention relates to mass transport field and plastics blanking die field, specifically is to being installed in the special-purpose blanking die that plastic scrapers on the chain carries out whole stamping-out.

Background technology

Chain generally is installed on conveying equipment, scraper plate is installed on chain,, move ahead, realize the conveying of material by scraper flight animal material along with the motion of chain.Two kinds of plastic materials of the general employing of scraper plate: a kind of is the high density polyethylene (HDPE) material, and another kind is the ultra-high molecular weight polyethylene material, and the molecular weight of ultra-high molecular weight polyethylene reaches 4,500,000, and the scraper plate of doing with ultrahigh molecular weight polyethylene promptly is called the superelevation scraper plate.Superelevation scraper plate surface smoothness height, anti-wear performance is outstanding, long service life, but because it is mobile poor, can only use sulfidization molding technology to make, its traditional preparation method is: the sheet material that earlier the ultra-high molecular weight polyethylene powder is sulfided into scale with the massive plate vulcanizer, again sheet material is made the scraper plate of corresponding profile with plate shearing machine or wood carving mechanism by certain discharging method, drilling installing hole and remove chain by dead slot on the scraper plate of corresponding profile again with the milling machine milling, obtain superelevation scraper plate as shown in Figure 1, installing hole 31 drillings form among Fig. 1, and chain forms by dead slot 32 millings.More loaded down with trivial details with traditional fabrication method operation, production efficiency is low, and the dimensional uniformity of the superelevation scraper plate of making is poor.

Summary of the invention

Make the defective that superelevation scraper plate dimensional uniformity is poor, operation is loaded down with trivial details, production efficiency is low for overcoming in the prior art, the invention provides a kind of superelevation scraper plate blanking die, can the good superelevation scraper plate of whole stamping-out dimensional uniformity, raise the efficiency.

The technical solution used in the present invention is: comprise part of the upper die and part of the lower die, the part of the upper die has die shank, top plate, sanction material cutter, fixed head, guide pin bushing, towards pin and square drift, the die shank bottom is vertically fixed on horizontally disposed top plate end face, the die shank top connects the slide block of punch press, fixedly mount fixed head under the top plate on the bottom surface, sanction material cutter vertically downward is set on the back plate face of fixed head; Guide pin bushing, all distinguish fixedly connected fixed head bottom surface vertically downward towards pin and square drift, guide pin bushing has 2, towards pin and square drift between two guide pin bushings, towards the appearance and size of pin and the single installing hole consistent size on the superelevation scraper plate, 2 chains on the appearance and size of square drift and the superelevation scraper plate are by the dead slot consistent size; The part of the lower die has guide pillar, die, lower plywood and stripper, the die secured in parallel is on the lower plywood end face, the guide pillar upper end is enclosed within the guide pin bushing and can slides up and down in guide pin bushing, the fixedly connected horizontally disposed die end face in guide pillar lower end, backgauge bar locating slot after having left and right two on the and arranged on left and right sides end face of die, backgauge bar locating slot lays respectively at the inboard of two guide pillars after two, after two, all fixedly install the back backgauge bar of L type in the backgauge bar locating slot, fixed placement stripper above the backgauge bar after two; The leading flank of die has two preceding guide bar locating slots, two preceding guide bars are parallel with die and be fixedly set in respectively in two preceding guide bar locating slots, two preceding guide bars stretch out to the die front portion, and a plurality of holder nails are set between two preceding guide bars, guide bar before vertical connection of holder nail one end.

The present invention is whole blanking die, and the stamping-out finished product is 2 of 1 moulds, has at utmost improved production efficiency, has reduced cost, simultaneously owing to installing hole and finished product profile while stamping-out, has improved the precision of installing hole, has guaranteed dimensional uniformity.
