Embodiment
At traditional automatic winding machine (after for example successively finishing the coiling of the moulding of preceding wire foot 101 of the described filament of Fig. 3 and wire body 100 on applicant's the LR-RS-V modified model automatic winding machine, the cut-out and the moulding of wire foot 102 after utilization filament pin cutting moulding device of the present utility model is as shown in Figure 4 finished, this device can be installed on for example aforesaid modified model automatic winding machine, to utilize its power and hardware, software resource.Wherein, because back wire foot 102 draws from wire body one end, so back wire foot and wire body parallel axes and to go out the pin direction opposite with preceding wire foot are employing cutting direction and wire body axially parallel.According to embodiment of the present utility model, make a stationary knife 18 and cover half 17 against back wire foot 102 earlier, cut off back wire foots 102 with a moving knife 14 again, moving knife 14 is double do shaping mould will after wire foot 102 bendings and silk pressing pin and moulding.Describe this process in detail below with reference to Fig. 4.
Fig. 4 illustrates the filament pin cutting moulding device structure chart of the utility model one embodiment.As shown in Figure 4, a base that can move forward and backward 1 is housed on the machine works table top, the flat board 2 that placement can horizontally rotate on base 1, but track base 4 moving up and down is installed in the stand 3 of installation move left and right on dull and stereotyped 2 in the side of stand 3.The left and right directions of the moving of the fore-and-aft direction by base 1, dull and stereotyped 2 rotation, stand 3 move and moving up and down of track base 4 can obtain satisfactory service position.
First guide-track groove 5 has been installed on the track base 4, but first slide block 6 of along continuous straight runs slippage has been housed in first guide-track groove 5.Stationary knife 18 and cover half 17 are installed on first slide block 6, with moving of first slide block, 6 left and right directions.Cover half 17 can be parallel to the axial left and right adjusting position of this wire body.
An one top shoe tooth bar 7 and a sliding block tooth bar 8 are arranged among the second guide-track groove 6a in first slide block 6.Top shoe tooth bar 7 is connected with push rod 12 with the upper end of the bell crank lever 11 that can swing, and the end of sliding block tooth bar 8 is equipped with rotating moving knife 14 by bearing pin 13.The gear 16 that is arranged in first slide block, 6 inner chambers and is fixed on the track base bearing pin 15 meshes with top shoe tooth bar 7 and sliding block tooth bar 8 respectively, both is produced oppositely move.
When the bell crank lever in the stand 3 11 is subjected to machine pull bar (figure does not show) pulling, in push rod 12 pushing courses, push down first slide block 6 and top shoe tooth bar 7 by the compression spring 10 between first slide block 6 and bell crank lever 11 earlier, they are moved to the left synchronously.First slide block 6 drive cover half 17 and stationary knife 18 from first direction (from right to left promptly) against back wire foot 102, wherein cover half 17 is against the bending position in wire foot 102 outsides, back, and stationary knife 18 is against the off-position in wire foot 102 outsides, back, shown in Fig. 6 A-6B.After moving a certain distance, there is a stopping means 9 to make first slide block 6 static and top shoe tooth bar 7 continues to move, and drives moving knife 14 by sliding block tooth bar 8 and move.The moving knife downside has specific curved surface 140 (with reference to shown in Figure 5), and this curved surface contacts with strutting piece 19.Moving knife 14 is supported on the moving knife downside by strutting piece 19 (being miniature bearing in the present embodiment) in motion process particular curvature 140 is finished and is risen and translation around bearing pin 13 rotations.Moving knife 14 has blade 141, and in the moving knife motion process, blade 141 can arrive the off-position of wire foot 102 inboards, back and cut off the back wire foot from second direction (promptly from left to right).Moving knife 14 also has a dynamic model boss 142, and dynamic model boss 142 cuts off the bending position of wire foot 102 backs in back from wire foot inboard, second direction arrival back at blade 141, cooperates cover half 17 to make back wire foot 102 in bending position bending laterally.The result is, makes stationary knife 18 and cover half 17 against back wire foot 102, cut off filament with moving knife 14 and with wire foot bending, silk pressing pin and moulding more earlier.
The cover half boss that Fig. 7 illustrates dynamic model boss on the moving knife and cover half fits into the schematic diagram of wire foot moulding behind the portable lighter silk.Wherein cover half 17 has a cover half boss 17a, and cover half boss 17a is made of curved silk face 17b and silk pressing face 17c, and the angle of the two is less than 90 °.Moving knife 14 has dynamic model boss 142, and dynamic model boss 142 is made of curved silk face 14b and silk pressing face 14a, and the angle of the two is less than 90 °.By cooperating of cover half boss 17a and dynamic model boss 142, can make wire foot form the bendings of 90 degree.Mobile cover half 17 can be regulated the distance of head folding silk point with the curved silk face 14b of dynamic model boss 142 of cover half 17, and both leave the slit of at least one filament diameter.
This apparatus structure requires compact, motion quality of fit height such as slide block, guide rail, and the repeated control precision height of movement position, material requirements has good resistance to wear, and each movement parts surface roughness requires high.And adopt a gear can reach the purpose that changes the direction of motion, and have compact conformation, stable transmission function in conjunction with the structural design of two tooth bars.
Because the wire foot size of two-fold footlights silk is all smaller, so the control of size b (with reference to shown in Figure 3) just guarantees by the precision of moving knife width.
Mobile cover half can be regulated the distance of cover half boss head folding silk point and the curved silk of dynamic model boss face, and both leave the slit of at least one filament diameter.
As shown in Figure 7, moulding plays a crucial role the silk pressing face 14a on the dynamic model boss 142 to wire foot with respect to the angle of bending silk face 14b.The difference of the difference of the difference of filament diameter, filament coiling ratio, bending wire foot fillet and the material of filament itself, filament linearity etc. are all influential to the spring back angle after the wire foot moulding.This can solve by the pressure angle angle on the flat board on the rotating base 12 or reconditioning dynamic model boss, the cover half boss.
Filament pin cutting moulding device of the present utility model can make full use of the hardware and software on the existing automatic winding machine, reduce the design work amount, in use, for example utilize actuating force and installation site on this spiral filament forming machine, one step finished and cuts off and bending, thereby change the just difform filament of energy coiling of parts, enlarge the scope of application.And the repeated control precision of the motion cooperation of cut-out shaped device and positioning control accuracy, movement position can both satisfy the long-term continous-stable operation of equipment.In addition, each component locations of cut-out shaped device of the present utility model can be regulated, to guarantee the controllability of wire foot length, bending height, wire foot all directions angle.
Though the utility model discloses as above with preferred embodiment; right its is not in order to limit the utility model; any those skilled in the art; in not breaking away from spirit and scope of the present utility model; when doing a little modification and perfect, therefore protection range of the present utility model is worked as with being as the criterion that claims were defined.
