BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a bending spinner spacing adjusting device capable of adjusting a bending spinner of a forming part of a wire product molding machine to a desired width from a plate.

Wire product molding machine is capable of manufacturing various kinds of wire products including spring, and is mainly composed of leveling part, power transmission part, bending part and molding part. Double molding part is installed radially around the wire nozzle of plate. It consists of several tools and bending spinners, each of which is configured to bend the wires drawn through the wire nozzle into a given desired shape by selective sliding operation by the cam and the LM guide.

As described above, the bending spinner having the molding part has a rotating shaft 102 having a molding protrusion formed on the fixed shaft 100 having a guide groove at an end thereof, as shown in FIG. It is configured to slide along the slide block of the, and the wire drawn out from the wire nozzle 108 and passed through the guide groove of the fixed shaft 100 is configured to be formed by bending the forming protrusion of the rotating shaft (102).

Accordingly, the bending spinner 110 has a narrow gap between the plate 112 and the gap adjustment cannot be made by itself in the configuration. If it is longer than the distance between the 112 and the bending spinner 110, it is impossible to be formed by contact with the plate, so when forming this type of product, the slide block of the LM guide 106 and the bending spinner 110 are connected at the time of setting. An auxiliary block having a desired thickness is formed between the base block 114 to make a gap between the plate and the bending spinner, and the power of the motor 104 is transmitted by a spline shaft having a universal joint.

However, when the auxiliary block is used to increase the distance between the bending spinner 110 from the plate 112, the weight of the auxiliary block is equal to the distance of the bending spinner 110 from the slide block of the LM guide 106 even though the weight of the auxiliary block is occupied. Since a large unloading load is generated, the sliding operation of the bending spinner 110 by the cam cannot be performed smoothly, and thus, the wire drawn out from the wire nozzle 108 is unstablely coupled in the guide groove of the bending spinner 110. Since it causes defects, it leads to a decrease in productivity and the dimensional change of the product is so severe that precision products cannot be produced.

In particular, the eccentric load generated during the use of the auxiliary block for adjusting the spacing becomes larger as the spacing between the plate 112 and the bending spinner 110 becomes larger, so that the spacing that can be opened is limited and can be molded. Is limited and accordingly, the use value of the equipment is lowered. Furthermore, when molding a product that does not require the interval adjustment through the auxiliary block, the auxiliary block must be removed to prevent product defects and improve quality. Detachable has a lot of problems, such as difficult to be difficult and difficult and also takes a lot of replacement time, so as to further reduce productivity.

SUMMARY OF THE INVENTION In view of the problems with the prior art described above, the present invention provides a simple and large width adjustment of the bending spinner from the plate of the forming part of the wire product molding machine by the power of the motor.

The interval is configured to be adjusted.

The slide base 12 in which the bending spinner 14 is installed above is long before and after, and is horizontally fixed near the wire nozzle 30 of the plate 10. The lead screw 18 and two LM guides are disposed on an upper surface thereof. (22) and (24) are installed side by side and the slide plate 32 is connected between the slide block of the LM guide and the splitting nut of the lead screw, and two LM guides 34 (top) on the upper surface of the slide plate 32 ( 36 is installed side by side and the base block 38 is fixed to the bending block 14 is installed on the slide block of the LM guide, the base block is connected to the cam 40 and the link 42 slide Sliding operation is performed by the cam 40 from the plate 32.

Bending spinner 14 used in the present invention is a general structure consisting of a fixed shaft 44 and a rotating shaft 46, the fixed shaft 44 is a gear having a long guide groove 44a at the end and has in the gear chamber Is rotated in engagement with the rack gear of the air cylinder 48 and the rotating shaft 46 is installed to rotate the fixed shaft 44 to the shaft and the forming projection 46a eccentrically at its end is fixed shaft 44 Protruding to the same height as the guide groove (44a) of the is connected to the motor (16) through the gear in the gear chamber.

In addition, the support base 13, in which the motor 16 is installed, is also long before and after, and is fixed to be perpendicular to the plate 10 as well as the slide base 12, and the lead screw 20 and two on one side thereof. The LM guide 26 is installed side by side, and the slide bracket 49 and the joint bracket are fixed between the split nut of the lead screw and the slide block of the LM guide, and the motor 16 is fixedly installed through the joint bracket.

The bending spinner 14 and the motor 16 are connected to the spline shaft tube 50 and the universal joint. The gear of the universal joint on one side is engaged with the gear of the rotary shaft 46, and the gear of the other universal joint is the motor. The power of the motor 16 is transmitted by being engaged with the gear of 16, but connecting the motor 16 with the other universal joint and the gear is to reduce the installation space. Even if the structure that can transfer the power of the motor to the rotating shaft is all satisfactory.

On the other hand, the lead screw 18 of the bending spinner 14 side and the response screw 20 of the motor 16 side have timing pulleys 54 and 56 connected to their ends, respectively. The motor 52 is fixedly installed between the 56 and the timing belt is configured to rotate at the same time by a single motor.

The wire product molding machine (A) to which the present invention is installed obtains various kinds of wire products by the selective use of several tools 58 and bending spinners 14 of the molding part 10. When the product is to be molded using the cam 40, the base block 38 connecting the cam 40 and the link 42 is connected to the wire nozzle 30 together with the bending spinner 14. The sliding operation is performed so that the guide groove 44a of the fixed shaft 44 is positioned on the same line as the wire nozzle 30, and the motor 16 is maintained in the connection state by the spline shaft tube 50.

When the wire 60 drawn out from the wire nozzle 30 is protruded to the desired length through the guide groove 44a of the fixed shaft 44 at the beginning of the molding operation, the rotation shaft 46 is rotated by the motor 16. The forming protrusion 46a of the rotating shaft bends the wire 60 protruding from the fixed shaft 44.

At this time, the bending spinner 14 is connected to the slide base 12 fixed to the plate 10 through two LM guides 22 and 24 from the slide plate 32 which is reliably connected to the LM guide 34 ( 36 and the sliding block of the LM guides 34 and 36 of the slide plate 32 with the base block 38 therebetween, so that the bending block 14 has a minimum distance. Is a flexible and smooth sliding operation with a minimum load, and thus the wire 60 drawn from the wire nozzle 30 can enter deeply into the guide groove 44a of the fixed shaft 44 without any interference. The bending work can be done precisely without changing the length or malfunction.

In addition, since the bulk of the wire product to be obtained or the length of the bending part is long, the bending part 14 may be in contact with the plate 10 during the molding operation by the bending spinner 14, and thus, the interval of the bending spinner 14 needs to be adjusted. In this case, when power is applied to the motor 52, the slide plate 32 having the bending spinner 14 along the split nut of the lead screw is rotated by the rotation of the lead screws 18 and 20 from the slide base 12. Since the motor 16 slides back and forth along the LM guides 22 and 24 and at the same time, the motor 16 slides back and forth along the LM guides 26 and 28 of the support base 13 so that the gap with the plate 10 is adjusted.
