(4) description of drawings: Fig. 1 is a schematic top plan view of the present utility model, and Fig. 2 is a front elevational schematic.

(5) specific embodiment: describe details of the present utility model and working condition in detail below in conjunction with Fig. 1, Fig. 2.Upward load onto a bent axle (8) with bearing block at lathe bed (62), connecting rod (38) is housed on the bent axle, connecting rod is connected with slide block (40) by cruciform joint (39), and slide block is connected with the drift that is equipped with mould (41).Be equipped with clothes hanger on the drift and need diastrophic mould.One end of bent axle is equipped with bevel gear (9) and goes up bevel gear (10) engagement with another axle (11), edge cam (12) is equipped with in this centre, the axle other end is equipped with bevel gear (13), this bevel gear again with bevel gear (14) engagement of another axle on (15), this a end is equipped with eccentric wheel (17), connecting rod (18) is housed on the eccentric wheel, and connecting rod is connected with the cutoff tool piece (37) of tool rest (36) lining by joint (35).The other end of these (15) is equipped with the large bevel gear (16) that there is the umbrella tooth part, and it is exactly not all to be that tooth is arranged on this bevel gear that there is the umbrella tooth part, but the centre has one section not have tooth.Large bevel gear (16) again with small bevel gear (19) engagement of another axle on (20), there are all cams (21) in a garden and an eccentric wheel (22) in this centre, car band (23) extremely is housed on the eccentric wheel, returnning (26) and pull bar (30) are equipped with in the termination of this axle (20), pull bar is connected with the slide block (32) of slide (31) lining, and feed cylinder (33) is housed on the slide block.Feed cylinder (33) is that feeding is used, also fix a fixedly feed cylinder (34) on the lathe bed (62), when feed cylinder (33) blocks material and send forward, fixedly feed cylinder (34) is decontroled, when feed cylinder (33) when returning, feed cylinder (34) blocks material and can not fall back, this feeding campaign all is to be passed by the umbrella tooth on the bent axle (8) to come, the intermittent motion of feeding is to have tooth to cause because gamp tooth (16) is gone up the part, do not have the place of tooth and the cone pinion (19) on the axle (20) just not to mesh to large bevel gear, axle (20) just should not rotate, just not feeding yet, do the pause in gap, this will say with the back that clothes hanger need be shaped needs the time relevant.Simultaneously, axle fix on (20) one garden week cam (a 21) and eccentric wheel (22), car band (23) extremely also is housed on the eccentric wheel, this all is to be exactly to stop in order to make axle (20) stop, and changes to transfer setly, prevents that just inertia from making (20) rotation.The other end of bent axle (8) is equipped with a sprocket wheel (5), and chain (6) is arranged on the sprocket wheel, chain be fixed on workbench (63) on power transmission shaft (48) on sprocket wheel (7) be connected.The power resources of bent axle (8) are in motor (1) and belt pulley (2), belt (3) and drive the belt pulley (4) on the bent axle and bent axle is rotated.Fix two sector gears (49) and rack shaft (45) engagement on the power transmission shaft (48), gear (43) is equipped with in the upper end of axle (45), the axial location of gear (43) is fixed, the upper end of axle (45) and the hole of gear (43) are loose fit, gear (43) is gone up the decentre position and is fixed a short pin (44), sprocket wheel (50) is equipped with in the centre of power transmission shaft (48), sprocket wheel (52) on sprocket wheel has chain (51) and is fixed on workbench on the axle (57) is connected, two sector gears (58) and the engagement of slidably two-sided tooth bar (46) on workbench are housed again on the axle (57), the another side tooth of two-sided tooth bar and gear (43) engagement, the back of two-sided tooth bar (46) and rack shaft (45) with below the spring (47) that pulls down backward is housed, (59), gear (53) and third wheel (54) engagement are housed on the axle (57), third wheel meshes with gear (55) again, be equipped with on the gear (55) and pull out material bar (56), spring (64) also is housed on the workbench (63), (65) mobile device.Owing to sector gear is housed on the power transmission shaft (48) and rack shaft is meshing, when therefore rack shaft and sector gear mesh, rack shaft just rises, retract by spring (59) when not meshing, the upper end of axle (45) and the hole of gear (43) are loose fit, so gear can rotate at axle head, the hole of gear (43) can be stretched out in the upper end of axle (45), add cog (43) and upward fix a short pin (44) in the decentre position, when material (66) has arrived between short pin and spool (45), and when axle (45) just in time stretches out gear (43), just can make material winding.Gear (43) is to be driven by two-sided tooth bar (46), and two-sided tooth bar has sector gear (58) to drive again, and the back of tooth bar is drawn spring (47) again, and tooth bar is resetted, and in the process that tooth bar resets gear (43) is also resetted.From top situation, the place of sector gear drive work is arranged, all be gap work, also all repeat work, this intermittent motion with the feeding of preceding said mistake all matches.The lever (27) of double headed roller contact is housed on the face of edge cam (12), a contact contacts with cam (12), another contacts with the driving belt (60) of straightener (61), lever is supported by the fulcrum (28) that is fixed on the lathe bed (62), and lever one end has the spring (29) that is fixed on the lathe bed to hold.The straightener intermittent motion is named by this cover mechanism, and when cam jack-up lever, the contact that contacts with belt just leaves belt, and straightener is with regard to stop motion, and when cam put down lever, contact just compressed belt, and straightener is work just.The end face of large bevel gear (16) has cam surface, and cam surface contacts with the contact of rocking bar (25), and the other end of rocking bar has contact equally, and contact contacts with the garden side face of garden week cam (21), all is equipped with coil tension spring (24) on two contact of rocking bar.This cover mechanism is used for killing automobile-used.Drift (41) is equipped with formpiston, and workbench is equipped with former on (63).Material (66) is with regard to the steel wire in garden.The utility model is explained as can be seen by above-mentioned, and the steel clothes hanger can once be made success, and whole clothes hanger has only a pad, therefore simplify technology widely, improved production efficiency, saved raw material, economize man-hour, reduced product cost significantly.
