A wire supply servo motor and the like for driving the lamp are separately provided.

Hereinafter, the operation of the spring forming device according to the present invention.

First, when the wire is driven in accordance with the key operation of the control panel unit 150 from the state in which the wire is wound through at least one flag pole 112a provided on the wire stand 112, the servo motor of the wire stand 112 The wire is released to the roller frame unit 116 for spring molding as the wire is released, wherein the wire stand 112 is driven at a predetermined speed according to the on-drive. Of course, the driving speed of the wire stand 112 can be reset to an appropriate speed according to the working environment.

In addition, the wire supplied at a constant speed from the wire stand 112 is provided to the roller frame part 116, which is provided in the roller frame part 116 and at a predetermined speed according to the control setting of the microprocessor 154. The wire is set through the wire supply sleeve 170 formed on the central axis of the front surface of the face plate unit 130 via the wire supply driving gear 116 and the wire supply roller 120 according to the driving force of the predetermined motor to be driven. It is supplied in length and speed.

Subsequently, the wire to be supplied is provided to the face plate unit unit 130 so that a molding process is performed with a spring having a predetermined shape, thereby providing the molded spring.

Here, the spring forming process will be described in more detail.

First, in the state where the wire is supplied on the face plate unit 130 mounted on the main frame panel as described above, the eight wire forming units radially formed on the main frame panel show a sequential driving state. The tool slide 136 provided to such a wire forming unit receives a driving force of a gear 132 that rotates by a driving force of a predetermined servomotor, and is connected to one side of the gear 132. According to the linear reciprocating motion, the supplied wire is formed by bending, coiling, cutting, etc. by the molding units 138a, 138b, and 138c.

That is, when any one of the tool slides bends the wire and returns to its original position while being driven forward to the wire supply sleeve 170 according to the driving of the cam 134, another tool slide (for example, the coiling tool slide) Is driven forward to coil the bent wire. Subsequently, the predetermined position of the coiled wire is cut and supplied by a predetermined tool slide having a cutting edge on the end.

Here, in forming the wire, the shape of the bent portion may be variously manufactured by the end shape of the tool slide 136 provided on the face plate unit 130 or the operation dimension of the control panel. For example, when a user wants to bend the end of the coil spring formed in a round shape, the desired round shape bending process is performed by providing a tool for forming a tool slide accordingly.

Then, the spring forming operation is performed by the above process, where the operator starts the spring forming operation in a state where the tool slide unit 136 is set to an appropriate position, the tool slide unit 136 is a constant detector If the wire is molded according to the initial value set by the sensor sensing operation of the drawing (not shown), but the spring is not formed accurately, the operator can adjust the desired spring shape by adjusting the position of the tool slide 136. You will be provided.

For example, when the spring formed by the key operation or the like is not molded correctly, the worker manually clamps the position of the tool holder 137 by rotating the adjusting bolt 136a provided in the side portion of the tool holder 137 in one direction. The position of the tool slide 136, which is driven forward toward the wire supply sleeve 170, is varied by changing the left / right direction about the reference point (A) of 162, so that the length of the spring can be readjusted. It will be possible.

On the other hand, the spring forming apparatus of the present invention is provided with a drive confirmation window 166 so that the operator can directly check the series of processes for the spring forming described above, the drive confirmation window 166 is the opening and closing cover 164 It is possible to prevent the spring-formed and mounted to be separated from the face plate unit 130. In addition, since the lighting lamp 128 is further mounted on the face plate unit 130 side, the operator can easily manage the equipment even in a low illumination time period through the driving confirmation window 166 by the light of the lighting lamp 128. Fine adjustment of internal parts can be performed safely.

And, the opening and closing cover 164 is configured as a gas shock absorber type, while the operator can easily open and close the process, as shown in Figure 7, the control panel unit 150 in the state equipped with such a gas shock absorber The oil in the oil tank 160 provided in the piston 162 opens and closes the piston valve and drives the piston 162 according to the flow resistance of the oil through the compression / expansion of the piston 162 according to the key operation. The opening and closing cover 164 is opened and closed. Here, the opening and closing cover 164 may be variously configured using air, as well as gas type.

Therefore, the opening and closing cover 164 is conventionally the foreign matter is inserted in the state in which the face plate unit 130 is exposed or the dust is accumulated in accordance with the use for a long time to increase the defective rate of the molded article or often damage the equipment itself On the contrary, the damage to the equipment can be effectively prevented by protecting the site where the wire is actually formed. At this time, when the face plate unit 130 is supplied with a wire and the molding operation is not performed according to the occurrence of an error such as the tool slide 136, the safety switch is automatically switched to the emergency stop mode. Will be prevented.

On the other hand, since the cam lever (124) is mounted on the upper frame portion 110 of the spring forming apparatus, a wire supply roller which is a control device for fixing and supplying the wire when the wire is put on the upper frame 110. Up and down adjustment of the lever (Wire feeding roller lever) 126 can be performed in a one-touch manner.

That is, when the wire supplied from the wire stand 112 is not correctly supplied to the face plate unit 130 from the state in which the wire feed roller lever 126 and the cam lever 124 are engaged with each other, the operator may be configured to use the cam lever ( By operating the 124 to adjust the height of the wire feed roller lever 126, it is possible to supply the wire accurately.

In addition, in order to block the leakage and inflow of oil introduced from the oil tank 160 in the process of opening and closing the opening and closing cover described above, the oil frame 144 is installed in the lower frame part 140 to improve the working environment. In addition, the lower frame portion 140 has a double-plate structure inside so as to distinguish the power line and the signal line in the wire arrangement to facilitate the electrical wiring work, and interference between such power lines and signal lines The noise contrast of the signal can be minimized.

On the other hand, according to the embodiment of the present invention limited to the spring forming apparatus for forming the wire supplied in the state in which the face plate unit 130 is formed in a vertical direction and a plurality of tool slides are mounted on the face plate unit 130 Although the number of other spring forming devices, for example, the number of the wire forming unit is different, or a variety of spring forming devices, such as the face plate unit is designed in the horizontal direction, it is possible to install a series of protective panel members for equipment protection, Even if the modifications other than the contents described in the present invention are projected, it should not be understood individually from the technical idea or the prospect of the present invention, but should fall within the claims appended to the present invention.

As described above, according to the spring forming apparatus of the present invention, in a device for forming a spring to be supplied with wires according to a certain key operation, a protective cover surrounding the equipment is mounted on the outside of the equipment, and the foaming is performed during spring forming. By allowing the operator to observe the process with the naked eye, the safety, operability and merchandise of the equipment can be improved, and the safety accident of the operator can be minimized.
