Abstract

The invention relates to a self coiling method for an ultra-long protecting sleeve spring which leads a spring steel wire into an automatic spring coiling machine through an aligning mechanism, a rolling wheel and a guiding plate to bend and coil to make into a spiral spring ring; the spring ring that is coiled extends outward rotatably along a V-shaped slot orbit arranged in a discharge port of the automatic spring coiling machine and is driven by a plurality of pairs of rolling wheels mounted on the V-shaped slot orbit to rotate deasil along the rolling wheels or two operating workers stand at two sides of the V-shaped orbit and use hand to deasil turnover the spring that is coiled ceaselessly until the protecting sleeve spring is finished to be coiled. The coiled spring of the invention has higher automation and manufacture quality of the protecting sleeve spring, uniform node distance of the spring and higher precision on the physical dimension of the spring; compared with the adopting a manual coiling by a latch, the invention can save massive spring coiling clampers and special tools as well as greatly save the working intensity of workers.

Description

A kind of automatically coiling method of overlength sheath spring
Technical field:
The present invention relates to the spring manufacturing process technology.
Background technology:
The helical spring manufacturing generally is divided into mandrel wind spring and no mandrel wind spring, the characteristics that the manufacturing of mandrel wind spring is arranged are that mandrel is contained on the chuck of lathe spindle, rotate with main shaft, main shaft makes pay-off move left and right on lathe bed of spring material by change gear and feeding leading screw, and spring material is tightly rolled into spring on mandrel.No mandrel wind spring manufacturing process then is to realize by automatic spring wind-, after spring steel wire is drawn from the charging tray frame, enter winding mechanism through aligning mechanism, running roller, guide plate, steel wire is lived by two coiling mastheads that are mutually 60 ° respectively, make the spiral circumferential running around the mandrel cutter, bending is wound into helical coil.And overlength spiral sheath spring, because spring length is more than 3 meters even above 3 meters, employing has the mandrel wind spring, wind spring mandrel overlength then, with high costs, be difficult to find suitable lathe, be not applicable to continuously the spring part of making in enormous quantities and there is mandrel around the automatic spring wind-of spring, automatic spring wind-has function of automatically cutting off, can independently finish the manufacturing of spring part, because in automatic wind spring process, along with sending constantly into of steel wire, the part moulding helical spring that coiling is good need constantly turn clockwise, and this is unlikely basically at automatic winding more than 0.5 meter to spring length.
Summary of the invention:
In order to overcome coiling overlength spiral sheath spring with mandrel coiling cost height is arranged, shortcoming such as mandrel is long, the present invention proposes overlength spiral sheath spring and adopts automatic spring wind-to roll a kind of new method.
Patent of the present invention solves technical scheme that its technical problem adopts:
At the discharging opening of automatic spring wind-spring the V-shape groove track of 5 °-15 ° of one horizontal tilts is installed, near discharge port end end height, the other end is then low.(as: the internal diameter of sheath spring after torsion machine is adjusted the various machined parameters of spiral sheath spring automatically, pitch), begin to carry out the coiling of overlength sheath spring, earlier spring steel wire is drawn from the charging tray frame, along with steel wire passes through automatic torsion machine aligning mechanism, running roller, guide plate, winding mechanism is lived by the coiling masthead without a break, make the spiral circular motion around the mandrel cutter, coiling goes out sheath spring is partly also made same frequency and speed along with this axial line of mandrel power circular motion, carrying out along with the sheath spring winding process, the sheath spring that is gone out by coiling is rotating along the V-shape groove track and is stretching out, several pair rollers are installed on the V-shape groove track, roller is by driven by motor, utilize the frictional force between roller and the sheath spring to drive, make the sheath spring that winds up along with roller turns clockwise.Two operators that perhaps stand in V-shape groove track both sides overturn along the sheath spring that is gone out by coiling clockwise with hand without a break, finish until this sheath spring coiling.
The invention has the beneficial effects as follows: the automation of coiling spring, the sheath spring workmanship is higher, and the spring pitch is even, the spring geometric accuracy is higher, relatively adopt the artificial coiling of lathe, can save in a large number, greatly alleviate working strength of workers around spring anchor clamps and specific purpose tool.
Description of drawings:
Fig. 1 is that the whole coiling system that realizes this winding method gets structural representation;
Fig. 2 is the location diagram of automatic spring wind-and V-shape groove track;
Fig. 3 is the schematic cross-section of V-shape groove track.
Among the figure: 1. alignment roller, 2. steel wire, 3. feeding running roller, 4. guide wire frid, 5. wind spring bar, 6. mandrel cutter, 7. pitch pawl, 8. cutoff tool, 9, V-shape groove track, 10 automatic torsion machines, 11, roller
The specific embodiment
Below in conjunction with accompanying drawing and example patent of the present invention is further specified.
Referring to Fig. 1, Fig. 2 box Fig. 3,2 millimeters steel wires of ¢ are installed on automatic torsion machine (model: Z53-8) on the bin, after piercing into alignment roller set and feeding roller wheels and guide wire frid, that adjusts spring lays out external diameter and pitch, as undesirable, the various parameters of or else disconnected adjustment go out qualified sheath spring test agent until coiling, through after the assay was approved, can begin normal sheath spring coiling.Steel wire 2 is earlier through after 1 alignment of alignment roller, drive through guide wire frid 4 by 3 rotations of feeding running roller, forced to be bent into circular arc by wind spring bar 5, steel wire 2 is made the spiral circumferential running by two wind spring bars 5 that are mutually 60 ° around mandrel cutter 6, and bending is wound into helical coil.The size of sheath spring pitch is to be controlled by pitch pawl 7, pitch pawl 7 moves vertically, presses the sheath spring pitch size and adjusts the position, and cutoff tool 8 and mandrel cutter 6 are after the sheath spring coiling finishes, volume heart linkage by cam control drives, and cuts off sheath spring steel wire 2.The sheath spring that goes out of coiling is carrying out spiral circle Zhou Xuanzhuan continually, rotating along the V-shape groove track 9 that is arranged on automatic torsion machine 10 discharging openings and to stretch out, and by several pair rollers 11 drives that are installed on the V-shape groove track, utilize the frictional force between roller 11 and the turn, make the sheath spring that winds up along with roller turns clockwise, finish until the sheath spring coiling.
Another kind of mode is two operators that stand in V-shape groove track 9 both sides, is overturn clockwise and moves along the sheath spring that is gone out by coiling with hand without a break by the workman, finishes until the sheath spring coiling.
Take out sheath spring at last, ¢ 9 hooks with the manual manufacture two ends, the sheath spring string that coiling is good hangs on the steel bar more than 4 meters, sheath spring is put into net belt type tempering electric furnace together with steel bar carry out qualitative tempering, 220 ℃ ± 10 ℃ of temperatures, tempering time 3H, the sheath spring air cooling of coming out of the stove after the tempering, sheath spring carries out middle temperature phosphating, and dipping lacquer is handled.
Stretching out automatically of turn for convenience, when V-shape groove track 9 is set, with its by automatic spring wind-discharging opening near-end to far-end 5 °-15 ° of horizontal tilts from high to low.
