Abstract

The utility model relates to an automatic ball cutter for steel wire, belonging to the technical field of steel wire ball forming. The automatic ball cutter for steel wire is mainly characterized in that a main shaft which is driven by a motor is fixed with a cam plate and a rotary head. The cam plate controls a feeder to feed incontinuously and synchronously, the rotary head cut. The structure used in the steel wire ball forming process has the advantages of simultaneous action and welltimed, automatic and accurate proceeding of cutting steel wires with fixed length.

Description

Automatic ball cutter for steel wire

The utility model belongs to steel wire bullet pellet forming technique field

Known in the art according to retrieval, the bullet pellet source that (repairing) ship unit uses the preliminary treatment steel of making is so far being followed a kind of pincers worker always and is carried out platform with equipment after with the wirerope share split and cut the method that shapes.This by the artificial steel wire bullet pellet of shearing, not only time-consuming, and the length inequality, be used for the plate quality after ball blast preliminary treatment steel plate often influences processing.China patent CN1060619A disclosed " low plate cut-to-length control method and device ", adopt the paper drive pulse counter controls to play the cutter point, with computer method of sampling control feed process, with travel switch of cutting motor control counting of cutting into slices, has at random, in real time, automatically and accurately carry out the advantage of cardboard fixed length cutting.Because this device is applicable to sheet material, therefore be unsuitable for the pellet fixed length cutting needs of wire rod.

The purpose of this utility model provides a kind of automatic steel wire cut pill machine with steel wire bullet pellet mass equivalent of fixed length cutting advantage.

Its solution is: this ball cutter supports main shaft and the cam disc that its end is fixed with cam disc by stock support and controls the feed appliance that is provided with on its stock support, and on orifice plate support one end of the supporting spindle main shaft that fixedly extend orifice plate and orifice plate support outer end thereof, adjustable rotary head is set, and further outward extending main shaft is connected with the output shaft of buncher by shaft coupling.

Automatic steel wire cut pill machine according to the such scheme manufacturing, carry out the action of clearance-type feed owing to control feed appliance by the rotation of main shaft drive cam disc, and determine the fixed length cutting amount of its steel wire by distance between rotary head and orifice plate, and be fixed in rotary head and cam disc run-in synchronism all the time on the main shaft, thereby have the production efficiency height, synchronously, in good time, automatically and accurately carry out the advantage of steel wire fixed length cutting.

Accompanying drawing has been described an embodiment of the present utility model.

Fig. 1 is automatic steel wire cut pill machine master TV structure figure of the present utility model.

Fig. 2 is feed appliance 1,6 sectional structure charts of this ball cutter.

As shown in Figure 1, the stock support 2 of this ball cutter is supporting the main shaft 8 that the end is fixed with cam disc 3, cam disc 3 contacts with rolling bearing 4 on the feed appliance 1,6 in rotary course by bead 5 and controls its feed appliance 1,6 that is arranged on the stock support 2 and carry out the autofeed action of clearance-type, and feed appliance 1,6 is uniform six or eight circumferential positions at stock support 2 of center with main shaft 8 center lines.Orifice plate support 10 1 ends at supporting spindle 8 are fixed with orifice plate 11, orifice plate 11 is circular (also can make squarely), for easy accessibility, orifice plate 11 manufactures two half blocks, every is separately fixed on the orifice plate support 10, orifice plate 11 inner rings are fixed with bearing block 13, and main shaft 8 is by 7,12 supportings of the bearing on bearing block 13 and the stock support 2.Orifice plate 11 is by being provided with the coak location and installation, and the via hole on it becomes radial radial arrangement, and the number when making cutting edge contact steel wire 9,14 cuttings of swallow-tail form blade 19 is minimum state, to reduce power consumption.The via diameter of orifice plate 11 is complementary with the steel wire that is cut 9,14 diameters, and orifice plate 11 has certain thickness, the cutting of the 16 pairs of steel wires of adjustable rotary head 9,14 that are provided with on the main shaft 8 that is beneficial to extend orifice plate support 10 outer ends.Rotary head 16 is provided with rectangular slot, and an end of its groove is a swallow-tail form, and cutting blade 19 embeds can be prevented in it going up coming off from this end; The other end is a square, and blade 19 is locked blade 19 by the latch segment 21 and the lock-screw 22 on swallow-tail form inclined-plane.Further the main shaft 8 that extends to rotary head 16 outer ends connects with the output shaft 40 of buncher 24 by shaft coupling 23, when buncher 24 changes, drive main shafts 8 by shaft coupling 23 and rotate, with the blade 19 cutting steel wires of realizing rotary head 16, and drive cam disc 3 control feed appliances 1,6 synchronously and carry steel wires 9,14 to put in place.Orifice plate 11 is adjusted by adjustment screw 17,18 and locking nut 41 with the gap 15 of rotary head 16 and is realized.When needs increased gap 15, adjustment screw 17,18 screwed in shaft coupling 23 certain distance locking nuts 41 rotary head 16 is compressed to shaft coupling 23 directions, and was close to orifice plate 11 by increasing pad adjustment sheet 20 to guarantee blade 19 cutting edges.

Fig. 2 has provided the structure situation of feed appliance 1,6.This feed appliance 1,6 is provided with a pair of

pressing plate

31,38, jump ring sheet 34,39 and the consistent

locking cutting ferrule

32,36 of

interior cover

33,37 specifications by receiver 28, wherein a locking cutting ferrule 36 is fixed in outside and another locking cutting ferrule 32 of receiver 28 by interior cover 37 and supports by tail springs 27 in its fixing guide finger 25,26 and the receiver 28 and form telescopic displacement formula structures, locks cutting ferrule 32 and is controlled by cam disc 3 by the rolling bearing 4 on the guide finger 25 thereby make.The front and rear card reed 34,39 of feed appliance 1,6 can not move backward to front slide, jump ring sheet 34 in the receiver 28 is fixed on the movable interior cover 33 by pressing plate 31 and

screw

29,30, the guide finger 25,26 of interior cover 33 upper ends can slide front and back in the slotted eye on the receiver 28, and guide finger 25,26 can play the effect that compresses jump ring sheet 34 simultaneously.When the rolling bearing 4 on the current guide finger 25 is subjected to bead 5 promotions of cam disc 3, locking cutting ferrule 32 moves backward, at this moment the steel wire rope material by the locking cutting ferrule 36 of front end stuck can not after move, the jump ring sheet 34 of locking cutting ferrule 32 that makes the back on steel wire 9,14 backward slippage be a fixed length, after bead 5 breaks away from rolling bearing 4, locking cutting ferrule 32 clamps steel wires 9,14 and under spring 27 thrusts the sub-thread of steel wire 9,14 is delivered to rotary head 16 endface position and stop, for the rotation cutting of blade 19 performs synchronous preparation.
