Description

Spring forming machine {A spring forming machine}

The present invention relates to a spring forming machine, and more particularly, to a spring forming machine capable of automatically rotating a quill shaft for guiding and supporting the wire forward to bend the wire, which is a material of the spring, into a coil shape.

In general, an elastic body is displaced as much as the load upon receiving a load, and has a characteristic of absorbing and accumulating the work as elastic energy. By using these characteristics and functions, the mechanical element used to select materials and shapes with a large elastic deformation relative to the load and to absorb and accumulate energy is called a spring. The above-mentioned springs include metal springs made of steel or copper alloy, non-metal springs made of rubber or synthetic resin, and fluid springs made of air or oil, and metal springs are coil springs or laminates according to their shapes. It is classified into spring, spiral spring and torsion spring.

Such a spring, in particular, a spring forming machine for manufacturing a coil spring has a plurality of blowers for forming a coil shape by sequentially striking the wire guided by the quill shaft and the quill shaft to guide and support the wire forward. At this time, the quill shaft has a shape in which one side is cut in order to prevent interference when the molding apparatus is hit in sequence.

However, since the conventional spring forming machine is manually operated to rotate the quill shaft toward the forming apparatus to be hit, there is a problem in that labor cost and work speed decrease.

The present invention was devised to solve the conventional problems as described above, the object of the present invention is a housing, and a quill shaft for discharging the wire is disposed in the center portion while being mounted on the front of the housing and a plurality of blowers on the radially outer side of the quill shaft With a molding apparatus disposed and a rotating device mounted inside the housing to selectively rotate the quill shaft, the spring manufacturing process is automatically performed to provide a spring forming machine that can improve work speed and reduce labor costs. It is.

In order to achieve the above object, the present invention,

A housing having a camshaft plate with a camshaft plate formed on its front surface, a molding device in which a quill shaft for discharging wires is disposed in the center portion of the camshaft plate, and a plurality of striking machines are disposed on the radially outer side of the quill shaft, and a rear surface of the camshaft plate. In the spring forming machine having a rotating device mounted to the selective rotation of the quill shaft, and a control device for controlling the molding device and the rotating device,

The rotating device includes a drive motor disposed on an upper side of the cam shaft plate, a first rotating gear disposed under the driving motor and fastened by being rotated by a driving motor and a rotating belt, and a first rotating gear below the first rotating gear. It is to provide a spring forming machine consisting of a second rotary gear which is rotated in engagement with the second rotary gear, and a third rotary gear which is rotated in engagement with the second rotary gear in the lower side of the second rotary gear, and is fixed to the quill shaft to rotate the quill shaft together.

As described above, according to the present invention, a housing, a molding apparatus in which a quill shaft for discharging wires is disposed in the center portion and a plurality of blowers are disposed on the radially outer side of the quill shaft, and mounted inside the housing. And by having a rotary device to selectively rotate the quill shaft, the process of manufacturing the spring is made automatically can improve the working speed and reduce labor costs.

Hereinafter, a spring forming machine according to an embodiment of the present invention will be described with reference to the accompanying drawings.

1 is a perspective view showing a spring forming machine according to the present invention, Figure 2 is an exploded perspective view briefly showing a rotating device mounted on the back of the camshaft plate of Figure 1, and Figure 3 is a cross-sectional view of the combined rotating device of Figure 2 .

1 to 3, a housing 10 having a cam-shape plate 12 having a cam shaft plate 12 formed at a front surface thereof, and a quill shaft for discharging a wire W at a central portion thereof while being mounted on the front surface of the cam shaft plate 12 ( A spring forming machine 100 having a molding device 20 in which a plurality of blowers 24 are disposed and a control device 30 for controlling the molding device 20 are disposed 22 and the radially outer side of the quill shaft 22. In the, further comprises a rotary device 110 mounted on the back of the cam shaft plate 12 to selectively rotate the quill shaft 22. At this time, the quill shaft 22 is a cut surface 26 is formed on one side for closeness and accuracy when a plurality of hitting machine 24 is hit.

The rotating device 110 is disposed inside the housing 10, that is, on the rear surface of the camshaft plate 12. The rotating device 110 includes a driving motor 112, a first rotating gear 118, a rotating belt 122, a second rotating gear 124, and a third rotating gear 126. The drive motor 112 is automatically operated by the control device 30, the drive pulley 116 is integrally mounted to the rotary shaft 114 formed on the drive motor 112. The first rotary gear 118, the second rotary gear 124 and the third rotary gear 126 are sequentially disposed below the driving motor 112. On one side of the first rotary gear 118, the rotary pulley 120 is integrally formed while protruding outward. The rotating belt 122 is fastened to the driving pulley 116 and the rotating pulley 120 to receive the rotational force of the driving motor 112 to the first rotating gear 118. On the other hand, the second rotary gear 124 is rotated while being engaged with the first rotary gear 118 on the lower side of the first rotary gear 118, the third rotary gear 126 is below the second rotary gear 124. It rotates while meshing with the second rotary gear 124. At this time, the third rotary gear 126 is fixed to the quill shaft 22 by a plurality of bolts 128 to rotate the quill shaft 22 together.

Hereinafter, the state of use of the spring forming machine 100 formed as described above will be briefly described.

In the spring forming machine 100 according to the present invention, a wire W, which is a material of the spring S, is transferred to the front of the housing 10 through the quill shaft 22. In order to form such a wire W into a coil shape, a plurality of blowers 24 rotate to strike the wires W being sequentially discharged. At this time, each striking machine 24 has to hit the incision surface 28 formed on one side of the quill shaft 22. Accordingly, the quill shaft 22 must be rotated so that the cut face 28 of the quill shaft 22 faces the striker 26 to be hit. In order to rotate the quill shaft 22 as described above, the driving motor 112 receives the signal from the control device 30 and the first rotating gear 118 fastened to the rotating motor 122 by the rotating belt 122 rotates.
