The specific embodiment

By illustrated in figures 1 and 2, cold-heading post forming machine, it mainly includes machine main body 1, drive motors 2, bent axle 3, cam 4, dead man 5, retainer bar 6, active sliding block, big push rod 7, little push rod 8, dashes cover 9, drift 10, thimble 11, anchor clamps and charging gear, described bent axle 3 is movably arranged on the machine main body 1, the one end is in transmission connection by belt pulley 12 and drive motors 2, provide power source by drive motors 2 to entire equipment, the other end fixed installation cam 4 of bent axle 3; Described dead man 5 is movably arranged on machine main body 1 outside, the one end contacts with the curved surface of cam 4, the outer end of the other end and retainer bar 6 flexibly connects, the inner end of retainer bar 6 is positioned at machine main body 1, can reset smoothly when working for the ease of dead man 5, back-moving spring 13 is installed at

dead man

5 and 1 of machine main body; Be provided with chute in the described machine main body 1, active sliding block is positioned at this chute, the middle part of bent axle 3 flexibly connects by connecting rod and active sliding block, one end of big push rod 7 contacts with active sliding block, other end overhead is at the leading section of little push rod 8, and the rearward end overhead of little push rod 8 is at the afterbody of drift 10, and drift 10 is nested with in the inside that dashes cover 9, drift 10 and dash between the cover 9 and be provided with back-moving spring 14, thimble 11 is movably arranged in the drift 10; Described anchor clamps mainly are made up of main die sleeve 15, tapered sleeve 16, main mould 17, latch segment 18, gland 19 and charging ram 20, described tapered sleeve 16 is nested with in main die sleeve 15, main mould 17 is nested with in tapered sleeve 16, latch segment 18 the conical surface place of tapered sleeve 16 and and main mould 17 between be provided with spring 21, gland 19 places 16 mouthfuls of places of tapered sleeve, described charging ram 20 is hollow form and is movably arranged in the main mould 17, is provided with back-moving spring 22 between charging ram 20 and the main mould 17; Described charging gear is mainly by vibrating motor 23, vibrating disk 24 and defeated material track 25 are formed, vibrating disk 24 is fixedly mounted on the vibrating motor 23, be provided with the feeding groove 26 of annular in the described vibrating disk 24, one end of defeated material track 25 and this vibrating disk 24 interior feeding grooves 26 dock, the other end is positioned at the top of retainer bar 6, so that retainer bar 6 can be got material in the lower end of defeated material track 25 smoothly, for the rivet that makes machine-shaping can fall smoothly, above described retainer bar 6 leading sections air nozzle 27 is installed, the strength of utilizing gas can be blown off the rivet of machine-shaping smoothly.

During work, driving bent axle by drive motors rotates, bent axle drives the dead man swing by cam on the one hand, dead man drives the retainer bar and moves forward and backward under the driving of cam, when the retainer bar moves backward to end, drop on the retainer bar under rivet on the defeated material track is lucky, when the retainer bar moves forward to the top, thimble is clashed into out just puts on rivet, bent axle slides before and after driving active sliding block on the other hand, when active sliding block during to front slide, thimble will at first be clashed into forward to be promoted, when thimble is through on the rivet, thimble will be pushed forward with drift, up to rivet being pushed forward in the tapered sleeve of anchor clamps, when the gland of anchor clamps is inwardly promoted by drift, being arranged on latch segment in the anchor clamps will inwardly shrink under the effect of the tapered sleeve conical surface rivet is pinned, contact with charging ram up to rivet, when rivet is continued inwardly to promote, rivet will be by the cold-heading post forming under the effect of bent axle motive force, thereby active sliding block is slided backward in chute and is removed thrust then, each parts of anchor clamps discharge rivet under the effect of spring, at this moment drift also resets under the effect of spring, rivet will together withdraw from along with thimble and drift, again return in the drift up to thimble, the rivet of machine-shaping at this moment will fall under the strength effect in nozzle simultaneously automatically owing to losing support force, has so just finished the process of primary production.
