Abstract

PURPOSE:To manufacture a coil having no torsion by inserting and holding a wire to be worked whose cross section is non-circular in the minor axis direction of the cross section by feed rollers, suppling it to a coiling device of a coil pin, a pitch roll, etc., through a guide and bringing the feed roller and the guide to deflection integrally. CONSTITUTION:A wire to be worked (b) is fed to a guide (c) through feed rollers a1-a3. Inserting and holding force of this feed roller is adjusted by an air cylinder. The wire to be worked (b) is fitted into a non-circular through-hole l of the guide (c) and brought to theta deg. deflection angle by the guide (c), supplied to a mandrel (d), bent to a prescribed curvature by coiling pins e1, e2 and a coil B is manufactured. A moving amount corresponding to the curvature of the coiling pin, a supply speed of the feed roller, a moving amount of a pitch roll (h), and a cutting machine (f) are controlled by an NC controller and synchronized. Also, by providing a means for bringing the feed roller and the guide (c) to theta deg. deflection angle, the roller can rotate against a plane. In such a way, a torsion caused by a variance of a cross sectional shape of the wire to be worked, and a torsion caused by a deflection angle of only the guide are prevented, and a service life of the feed roller can be extended.

one or more coiling bins e1, e2 having a mandrel d in a direction penetrating the plane at right angles to the plane A on the mouth side thereof, and arranged parallel to the plane A around the mandrel d;
In a coiling device having a cutting device Hf and a pitch tool h whose pitch applying surface can reciprocate in a direction penetrating the plane A, a non-circular cross-sectional line is used as the applied wire b; The cross-section of the through-hole 1 of the guide C is non-circular corresponding to the cross-sectional shape of the non-circular cross-sectional line, and the guide C is connected to the center of the bit tool h in the plane C through which the workpiece line b passes at right angles.

That is, in order to form a coil spring B having a cross-sectional shape as shown in FIG.
In Figure 1 of Publication No. 38054, the cross section of the sandwiched state between the wire to be processed and the guide groove of the feed roller is as shown in Figure 11.
It is necessary to hold the wire in the long diameter direction of the non-circular cross section, and the contact area between the guide groove of the feed roller and the feed guide and the processed wire is small. For this reason, there is a problem that the workpiece wire is tilted due to variations in the cross-sectional shape of the workpiece wire, causing twisting of the workpiece wire, or that the workpiece wire is similarly twisted due to rotation of the guide. Furthermore, the feeding of the wire to be processed may be impaired, and the frictional force generated between the guide groove of the feed roller and the feed guide becomes large, resulting in a shortened lifespan of the feed roller and the feed guide.

When i1b leaves a guide C having a non-circular through hole 1 corresponding to the cross-sectional shape of the wire b to be processed, the periphery of a mandrel d is provided at the mouth of the guide C in a direction parallel to the plane A. A plurality of coil bins e 1 are arranged perpendicularly to the plane A.
, e 2, the wire is bent to a predetermined curvature, and a coil B is formed in a direction parallel to the plane A. When a predetermined length is reached, the cutting blade q of the cutting device f advances to shear the wire b to be processed. te1
Coil B made in this way
is coiled and the wires are in close contact with each other, so if it is used as a tension coil spring, it can be left as is, but in order to use it as a compression fill spring, it is necessary to change the pitch between the coils. There must be a gap to allow for shrinkage so that there is no adhesion. The pitch tool h shown in FIG. 1 plays this role.The tip of the pitch tool h is above the plane A, and the pitch tool h rises vertically above the plane A. The coil-forming strands are gradually bent in the axial direction of the coil, and the pitch of the coil spring increases, allowing a gap to be provided. The coiling bins e1 and e2 can be adjusted in and out in the direction of the arrow j, and the coil diameter can be adjusted.
Although the movement of is omitted from the illustration, the feed roller a is moved by a cam.
1, a and 2, and by changing the coil diameter by feeding the processed wire b, it is possible to obtain conical, barrel-shaped, and hourglass-shaped coil springs. Further, 1 is a handle for rotating a worm 28, which will be described later, and 2 is a lock lever.

Then, the handle 1 of the worm 28 is rotated. As the handle 1 rotates, the worm 28 also rotates, and the worm wheels 2 and 9 that mesh with the worm 28 rotate, thereby rotating the box body 20. On the top of this box body 20, there are feed ports A1, A2,
Since 3 and the guide C are attached together, the guide C rotates with the same amount of rotation as the amount of rotation of the box body 20, and the guide C has an eccentric angle θ0. After setting the guide C to a predetermined eccentric angle θ0, the air cylinder 45 is pressurized to maintain the eccentric angle θ0 of the box body 2.0,
Further, by locking the lock lever 2 and the lock lever 38, the box body 20 is firmly held and fixed. In this way, the workpiece @b can be sent to the coiling housing via the feed rollers a1, a2, a3 and the guide C in an angled state.

[Effects of the Invention] As detailed above, the present invention is characterized in that the feed roller, the feed roller, and the guide are integrated to sandwich and feed the work piece having a non-circular cross section in the minor axis direction of the cross section. The structure is such that the deflection angle is θ0.

Therefore, it is possible to prevent twisting of the wire to be processed due to variations in the cross-sectional shape of the wire to be processed, or torsion of the wire to be processed due to deviation of the guide alone, and to extend the life of the feeder. Then, it is possible to obtain a coil spring in which the center axis of the wire to be processed is always perpendicular to the center line of the coil.
