The present invention relates to a steel wire bending machine that can be used in a variety of products by cutting a number of wires to a certain length, in particular, by bending in the X direction and Y direction at the same time by bending in the Z direction The present invention relates to a jet (Z) type automatic wire bending machine that can easily cut and bend the wire in the X, Y, and Z directions.

Conventionally, the wire supplied from one side is converted into a linear motion from a rotational movement to reciprocate a certain distance so that the wire is bundled and supplied, but this is to supply a wire that bundles the wire when using different wires of different thicknesses. We had to exchange wealth.

Therefore, it is necessary to provide the supply part according to the thickness of various wires, and if the supply part is used for a long time, the supply part is worn out and cannot be used. Therefore, it is necessary to purchase a new supply. There were disadvantages such as economic burden.

And the slide plate of each mold part is in contact with the main body, and both sides of the slide plate is formed in a trapezoidal shape which is diagonal, and the slide plate is always in contact with the main body by fixing it so as to be slidable by the fixing part at both sides. It has been formed.

Therefore, when foreign matter is caught between the slide plate and the main body, the slide plate is prevented from operating the slide. Thus, the foreign matter interferes the slide operation of the slide plate, which causes the defect of the product. If foreign matter gets stuck between the plate and the main body, the mold part must be disassembled to remove it, and the parts contacting the main body and the slide plate are easily worn by the foreign material, which increases the play flow of the slide plate. This is because there was a problem such as having to repair the slide plate and the body.

In addition, the existing wire automatic bending machine can be bent only in the X and Y directions in performing multiple bending of the supplied iron wire in a state of opening a square or circle or one side of a certain shape, so that the bent product is made of flat products only. In order to bend a product that is bent in a plane in the Z direction, which is a three-dimensional rectangular direction, as described above, a separate bending machine must be used to bend, so two bending machines are required to produce a single product. As described above, since the product is produced using two bending machines, the production speed of the product is slow and the unit price of the product increases.

The present invention has been made in view of the above problems, and it is possible to supply iron wires of various thicknesses by adjusting the gap between the upper and lower rollers to match the thickness of the cutting wire by turning the adjusting handle regardless of the thickness of the iron wire supplied. Then, the slide plate of the mold part is formed into diamond shape, and it is installed to maintain a constant gap between the main body and the slide plate, and a separate fixed stand is installed outside the support for fixing the slide plate to reduce the flow gap of the slide plate. It can be adjusted to reduce the occurrence of defective products due to the flow gap of the slide plate, and the upper mold part installed in the X, Y direction and the back side, the left and right mold part and the back mold part slide in a flat manner. By installing a separate front mold on the front of the bending machine to bend the steel wire The main purpose is to be able to bend in the Z direction of each direction to be able to bend the wire in the X, Y, Z direction in a single operation as described in more detail on the basis of the accompanying drawings as follows.

Looking at the operation and effects of the subject innovation constituted as follows.

As shown in FIGS. 1 to 10, when power is applied to the motor 61, the motor 61 is driven, and the driving force of the motor 61 is connected between the pulleys 63 and 66. The driving force is transmitted to the transmission 67 by the V-belt 64, and the driving force transmitted to the transmission 67 is a four-step rotation ratio of the driving force output to the output shaft 69 due to the operation of the shift lever 68. The speed of the work can be adjusted at will by the user.

The driving force output to the output shaft 69 of the transmission 67 transmits the driving force to the drive shaft 81 by the chain 72 connecting the sprocket 71 and the sprocket 73 of the drive shaft 81, and the drive shaft 81. The driving force transmitted to the 81 is transmitted to the standby gear 82 by the small gear 83 installed in the driving shaft 81, and the driving force is bitten by the peripheral edge of the standby gear 82 and the interlocking shafts 84 and 86. Since the small gears 85 and 87 installed on the driving shaft are driven in the same ratio as the rotation ratio of the small gear 83 installed on the driving shaft 81, the fixed gears are fixed to one side of the driving shaft 81 and the interlocking shafts 84 and 86. As the cams 55, 56, 57 rotate, the support pins 122 are fixed to the lower portions of the upper mold part 3 and the slide plates 37 of the left and right mold parts 4 and 5. The slide plate 37 slides forward in contact with the roller 121, and the advanced slide plate 37 is retracted by the holding force of the tension springs 105, 106, and 107.

The rollers 88 of the arms 89 are contacted by the protrusions 159 while the cams 59 fixed to the rear side of the interlocking shaft 84 are rotated so that the arm ( 89 is rotated to the left and right to retract the slide rod 94 of the back mold 7 and the retracted slide rod 94 is advanced by the holding force of the compression spring 97, the drive shaft The fixed plate 109 fixed to the rear side of the 81 is rotated to transmit the driving force of the driving plate 109 by the rod 115 so that the transferred power is transferred to the sector gear 117. The interlocking gear 21, which is geared to the upper portion of the sector gear 116 while rotating left and right around the hinge shaft 118, performs forward and reverse rotation as much as left and right rotation of the sector gear 116. Will repeat.

At this time, the power is transmitted to the one-way clutch 22 only when the interlocking gear 21 performs forward rotation, and when the interlocking gear 21 reverses, power is not transmitted to the one-way clutch 22. The drive shaft 23, the drive gear 25, and the drive roller 27 fixed to the clutch 22 only intermittently rotate forward, and the interlocking gear 26 engaged with the drive gear 25 is driven. Since the reverse rotation is performed at the same ratio as the gear 25, the interlocking shaft 24 and the interlocking roller 28 also perform the same rotation as the interlocking gear 26.

The sprockets 73 installed on the drive shaft 81 and the sprockets 76 of the connecting shaft 77 are connected and installed by the chain 75 to transfer the driving force transmitted to the drive shaft 81 to the connecting shaft 77. Then, the driving force is transmitted as the bevel gear 78 to the interlocking shaft 79 provided on one side, and the roller 121 mounted on the lower side of the slide plate 37 of the front mold part 6 is cam ( The slide plate 37 is advanced in contact with 58) so that the retraction of the slide plate 37 is retracted by the holding force of the tension spring 108.

In this way, the driving force of the motor 61 is transmitted to each of the cams 55, 56, 57, 58, and 59 so that the upper mold part 3, the left and right mold parts 4 and 5, and the front mold part 6 are provided. ) And back mold portion (6) to transfer power to allow the slide plate 37 and the slide rod 94 to move forward and backward, the drive roller 27 and the interlocking roller (28) of the supply unit (28) By transmitting the interstitial driving force to), it is possible to obtain a constant driving force at all times and at the same time to operate smoothly.

The bending machine 100 for transmitting and operating the accurate driving force as described above will be described in more detail as follows.

The rotational force input from the input shaft 65 changes by a reduction ratio of 4 units due to the operation of the shift lever 68 of the transmission 67 receiving the driving force of the motor 61, and is output to the output shaft 69. At the same time as this deceleration, the rotational force of 4 units can be obtained.

The position of the hinge shaft 114 is fixed by sliding the adjustment plate 111 fixed as the fixing bolt 113 to the fixing plate 109 fixed to the rear side of the drive shaft 81. Since the radius of rotation increases when the distance from the center of the position (109) increases, the distance that the sector gear 116 rotates left and right also increases, so that the rotational force of the driving roller 27 and the interlocking roller 28 increases. The moving length of the iron wire 132 can be adjusted, and the guide 103 slides left and right on the long hole 130 formed on the front support plate 119, thereby fixing it as a fixing bolt 131. 132) it is possible to adjust the position to be cut.

In this way, both sides of the slide plate 37 receiving the driving force are formed in a diamond shape, and the triangular slide grooves 35 and 47 formed on one side of the supports 34 and 46 supporting both sides of the slide plate 37. Since the center position is located in the upper center, the bottom portion of the slide plate 37 is separated by a predetermined distance from the front support plate 119 or the bottom plate 124, so that the slide plate 37 and the front support plate 119 or the bottom plate 124. Fixing bolts for fixing the support plates 34 and 46 for minimizing wear of the slide plate 37 and minimizing abrasion of the slide plate 37, even if foreign matter is caught between them. In the state of loosening (54) slightly, turn the adjusting bolt 53 to advance and retract the supports 34 and 46 to minimize the clearance that the slide plate 37 flows to the left and right. To minimize the occurrence of the slide plate (3 7) by turning the adjusting bolt 53 is screwed to the adjusting plate 43 fixed to the upper rear side of the upper back side to allow the various molds to be fixed to the fixing groove 38 to move forward or backward to the correct position. Adjust the mold to work.

The straightening unit 1 is fixed to the upper portion of the slide plate 16 because the slide plate 16 is moved forward or backward by turning the lever 18 forward or reverse when the wires 132 have different thicknesses. The roller 17 is also moved forward or backward to adjust the distance with the roller 17 is fixed to the upper portion of the fixed plate 115 to adjust the thickness of the iron wire 132 supplied evenly to the wire 132 You can unfold it.
