Description
Technical field:
The utility model relates to the spring production machine tool.
Background technology:
Traditional coiling machine, the helical spring pitch of its manufacturing and diameter are respectively greater than 3 times of steel wire diameter with in less than 30 times of scopes of steel wire diameter.Exceed this scope, spring structure is with destroyed, and elastic force is lost.Yet in life now, often need be at the spring outside the above-mentioned range limit, particularly little line footpath, coarse pitch, large diameter helical spring.When making this spring, need earlier, till being stretched to spring and slightly being out of shape with manpower then by making in the above-mentioned scope.The spring that this method is made, the one, can not restore fully, the 2nd, labor strength is big, the 3rd, and operating efficiency is extremely low.
Summary of the invention:
The purpose of this utility model provides a kind ofly can make the helical spring coiling machine of coarse pitch major diameter.
The utility model comprises motor-driven mechanism, steel wire straightening mechanism, steel wire feed mechanism, steel wire cutting-off mechanism, it is characterized in that steel wire feed mechanism output side is equipped with the radian controlling organization, and propeller pitch control system is equipped with in radian controlling organization top.The radian controlling organization is made up of the guide wheel of angular distribution, has at least a position adjustable in three guide wheels.The steel wire of advancing pressurized by these three guide wheels the time forms radian.The pitch control device has the adjustable regulating block in fenestra, position that passes for steel wire by the centre and constitutes, and its position is higher than the radian controlling organization, and the stamping knife of steel wire cutting-off mechanism is positioned at the regulating block top.Connect on the gear shaft of steel wire feed mechanism by counting scale and near dish week the steel wire length control device that one Hall element is constituted being housed along the position.
The utility model will enter three adjustable guide wheels in position from the steel wire that the steel wire feed mechanism comes out, with the helical spring diameter that form to need, when the distance of guide wheel 18,20 enough greatly the time, spring diameter can be unconventional, realized the diameter of 700mm in the experiment, promptly diameter is greater than 200 times in line footpath.When adjusting the position all around of regulating block 6, pitch also can be unconventional, realized the pitch of 1m in the experiment, be that diameter is greater than 200 times in line footpath, and can be by industrial single board computer control length, guide wheel position, regulating block position, stamping knife device, realize full-automatic operation, production efficiency improves, and has also guaranteed product quality.
Description of drawings:
Fig. 1 is the utility model frame for movement schematic diagram.
Fig. 2 is Figure 1A-A sectional view.
The specific embodiment:
With reference to Fig. 1, Fig. 2, motor driver, steel wire straightening mechanism, feed mechanism, radian controlling organization etc. are housed on the frame 17.Steel wire straightening mechanism is made of straightening frame 27 and jacking block 30, and hollow belt wheel 29 is fixed on the frame axle.Three adjustable jacking blocks 30 that are fixed on the straightening frame 27 squeeze steel wire curved to definite shape.Motor-driven mechanism is made of through belt wheel 26, V belt and belt wheel 29 motor 25, drives straightening frame 27 and does rotation at a high speed, be drawn out straightening frame 27 steel wire 28 linearity.Belt wheel 29, straightening frame 27 and belt wheel 31 are connected into one by hollow shaft, pass for steel wire.The power of steel wire feed mechanism from: belt wheel 31 is installed in straightening frame 27 opposite side axle center, is connected with the belt wheel 22 of reduction box 23 by belt, and reduction box belt wheel 24 is connected with belt wheel 15 belts, and driven gear 13 rotation.By the A-A cutaway view as can be known, gear 13 is by 9 rotations of gear shaft 12 driven gears.Gear 13 also drives pinch roller 32,34 simultaneously and rotates.Upper pressure wheel 35 and lower pressure wheel 33 are separately fixed on gear 9 and the gear shaft 12, and under hold down gag 36 effects, pinch roller 35 and pinch roller 33 are finished the work of sending to of steel wire in rotary course, can guarantee the enough crowded power of sending with two groups of pinch rollers.
The steel wire length controlling organization is made up of counting scale 8, proximity Hall switch 7 and presetting system counter; Counting scale 8 all is connected on the gear shaft 9 with pinch roller 35, and mark 14 is a dividing plate among the figure.8 weeks of counting scale, when pinch roller 35 rotated a circle, counting scale 8 also turned over a week along being evenly equipped with 20 straight pins, and equally distributed straight pin send 20 pulse signals for the presetting system counter through proximity Hall switch 7 on it.Can obtain the steel wire length of sending to when counting scale 8 revolutions are crossed 360 ° of lattice/20=18 ° by the diameter dimension of pinch roller 35.The steel wire length that need make spring by reality can be obtained the number that presets of presetting system counter.Send proximity Hall switch 7 is sent in the process pulse signal to when steel wire and reach this and preset when several, the counter normally-closed contact disconnects, and motor 25 quits work, and steel wire also stops to send to, thereby has effectively controlled the length of sending to of steel wire.
Cutting-off mechanism adopts punch body, and the belt wheel 38 of motor 37 is connected with punch press flywheel 39 by V belt.Clutch lever 4 is in upper limit position when flat, stamping knife 5 does not do to dash the work of cutting.When feed wire reaches setting value, presetting system counter normally-closed contact disconnects, motor 25 promptly quits work, its normally opened contact closure of while, electromagnet 2 is got, electromagnet push rod 3 promotes clutch lever 4 downwards to the lower position, and flywheel 39 promptly makes the stamping knife 5 descending steel wires 28 that block by clutch block.When electromagnetism push rod 3 is descending, its top breaks away from travel switch 1, the travel switch No. of delivering letters 1 resets it for the presetting system counter, electromagnet 2 dead electricity, clutch lever 4 resets under the spring force effect, stamping knife 5 promptly quits work after finishing an impulse stroke, and motor 25 restarts simultaneously, enters the 2nd periodic duty.
The diameter of spring is realized by the radian controlling organization.The radian controlling organization is made of three guide wheels 18,19,20 of angular distribution, and each guide wheel position is adjustable.The steel wire 28 that is straightened is sent through guide pad 21 through feed mechanism and is entered between guide wheel 19 and the guide wheel 18,20.When the needs diameter more greatly, then move on the guide wheel 19, guide wheel 18,20 distance widens, otherwise reduced then.
Pitch regulated piece 6 is installed in stamping knife 5 belows on the frame 16, but it highly is higher than guide wheel 19.Regulating block 6 laterally has the fenestra that passes for steel wire 28.Regulating block 6 positions can all around be adjusted, such as when it when the guide wheel group, pitch increases, on the contrary then pitch is dwindled.
