DE2332685A1 - Wire forming for saw-tooth steel wires - features radially guided periodically acting tools such as stamping or notching blades - Google Patents

Abstract

The deformation of wires or similar workpieces is for stamping saw-toothed all steel wires, with radially guided, periodically acting tools. The workpiece, which is passed by a stamping- or notching blade, is held for a short time according to the pitch of the required profile, e.g. the toothing. After engagement of the stamping blade, the workpiece is then further transported by the amount of pitch or feed. The feed amount is carried out in an interval less than the notching interval between two subsequent continuously rotating stamping blades.

A punching device R zvx production of Gonzstahl clothing wire D. for reels, take-off rollers or the like parts of carding devices has a punching wheel L with radially protruding notching knives 2 on a shaft 1. When the punching wheel L rotates in the circumferential direction, the latter touch »a raw wire D directed parallel to the punching rod shaft 1 in a vertical notch plane E.

The raw wire D is the feed roller * V according to the arrow t Pulled over a notch 3 hit punch 4. By The short-term notch drilling of the notch or punch knife 2 a recess 5 is cut out of the raw threat D; Respectively two adjacent such recesses 5 form a tooth 6 between them according to FIG. 3 the stepped profile F of the raw drape »D old of a blottstOck 7 as well as recognizing this "edge web 8"

The angle of rotation r ve 18 * (see ♦ w.) Between two notch bars 2 to one (FIG. 2) determines, with the associated speed of rotation of the punching wheel L and others, the lock rhythm for the punching process; Each time after passing through that arching line, one of the notching knives 2 hits the robing wire D. This is pulled at a constant speed by the feed device or the guiding shafts until the selected notch position is in the plane of the notch 2 lies; then rests dr Rohdroht D briefly until dsw Versdwbwalzen V ernetit occur "in T Ugkeit ·
