Description

Detailed Description of the Invention The present invention is used in the process of thinning (stretching) and straightening rolled wire, and the thin wire passes through the gaps between a plurality of combined rolls by the advancing force of the thin wire. The present invention relates to an apparatus for processing a continuous convex or concave pattern on the surface of a thin wire using the concave or convex pattern processed on the roll.

In conventional processing equipment of this type, multiple combined rolls are free from each other, and when a pattern is processed into a thin line, each roll rotates freely, and the pattern is placed at a fixed position in the length direction of the thin line. It often happens that the thin wire is not processed at the same position in the length direction, and the cross-sectional area in the length direction of the thin wire is not constant, resulting in variations in mechanical strength along the length of the thin wire. .

In addition, in a device in which the rolls are fixed to each other, the gap formed by the multiple combined rolls through which the thin wire passes is constant, and the pattern is processed only on the thin wire that is the same as the gap or slightly thicker, and the pattern is processed on the processed line. Each time the thickness of the thin wire changes, the roll must be replaced with a roll corresponding to that thickness, and as the convex pattern on the roll surface wears out, the depth of the concave pattern processed into the thin wire becomes shallower. However, in order to process a pattern of a certain depth, it is necessary to replace the rolls, which increases the number of rolls owned and has disadvantages such as a short lifespan of the rolls.

In order to improve these drawbacks, the present invention fixes four rolls, which are arranged on four sides and form gaps between the rolls through which the thin wire to be processed passes, at their respective relative positions by meshing gears. , and each roll is provided with a roll synchronization mechanism such that each roll is interlocked with each other via this gear, and the four rolls are approximately centered on the axis of each gear and the gap formed by the four rolls is freely changed. It is equipped with a roll-down mechanism that rotates in an adjustable manner, making it possible to accurately process concave or convex continuous patterns on thin wires of different thicknesses, and to process patterns with a constant pitch and depth. The purpose of this invention is to provide a high-quality deformed wire processing device that can be used.

Hereinafter, one embodiment of the apparatus of the present invention will be explained based on the drawings.
A gear 2 is concentrically attached to a roll 1 whose outer periphery has been processed into a shape corresponding to the cross section of the fine wire, and which has concave or convex patterns 1' at a constant pitch so as to be in contact with each other from both sides. Each roll 1 integrally attached to the stand body 11 is placed at a position through which the wire passes, and one end of each roll 1 is pivotally supported by a support pin 9 on each side of the stand body 11 to form a substantially triangular U-shape facing each other. A shaft 3 is mounted on the bottom of each individual frame 7, 7..., and the roll rolls 1, 1... are installed at relative positions with a phase angle of 90 degrees, and are separated from the shaft 3 of the roll 1. At the bottom of the frame 7 near the support pin 9 side, there are bevel gears 5 that are adjacent to each other so as to mesh with each other, and a gear 4 that meshes with the gear 2 on the side of the roll 1.
are rotatably mounted concentrically around a shaft 6, and a protruding pin 8 is provided at the tip of this frame 7, and a right angle is formed with the shafts 3 and 6 of the frame 7 as two points and the shaft 6 of the gear as a right angle part. Four similar blocks 10a, 10b, 10c, and 10d are constructed with support pins 9 mounted on the vertices of a triangle or a nearly triangular shape, and the support pins 9 of each frame 7 are attached to the four sides of the stand body 11. Along with pivoting, roll 1
The four rolls 1 are fixed at their respective relative positions by the meshing of the gears 4, 5, 5, etc., which mesh with the gear 2, and the adjacent similar bevel gears 5, 5 that are in phase with each other by 90 degrees, and Each roll 1 has the gears 4, 5,
5 constitutes a roll synchronization mechanism 12 that is interlocked with the roll synchronization mechanism 12.

The stand main body 11 is connected to an opposing stand 15 by a stay bolt 13 and a stay pipe 14, and this stand 15 is provided with cutout grooves 16 on all sides centering on the passage of the processed wire. The support metal 17 of the protruding pin 8 at the tip of the frame 7 fitted into the frame 7 and the support metal inserted into the notch groove 16
A roll-down mechanism 19 is provided which sets the roll 1 at a predetermined position via each frame 7 by attaching a roll-down screw 18 that moves the roll 1 along the frame 7 .

Each roll 1 is positioned between the support pin 9 of the respective frame 7 and the frame tip protruding pin 8,
By operating the frame protruding pin 8 with the reduction screw 18, it is rotated about the support pin 9 as a fulcrum, and the gap 20 formed between the rolls 1 can be changed to an arbitrary size.

Furthermore, when the roll 1 is rotated around the support pin 9, the bevel gears 5 and 5 also move at the same time, but the roll 1
The positional relationship between the support pin 9 and the bevel gear 5 is arranged as shown in FIG. This can be handled by minimizing the increase/decrease in the backlash of the bevel gears 5, 5 due to movement.

Further, it is desirable that all four rolls 1 have the same diameter, but rolls with different diameters can be used within the range of crushing of the bevel gear 5.

The apparatus for processing irregularly shaped wires of the present invention has the above-mentioned configuration, in which the thin wire a to be processed is supplied from the direction of the arrow in FIG. Due to the advancing force of the thin wire, the thin wire passes through gaps 20 of a preset size formed by four rolls 1 facing each other vertically and horizontally. When the thin wire a passes in contact with the rolls 1, each of the four rolls 1 is rotated, and all the rolls 1 are rotated by the mutually meshing bevel gears 5, 5 and gears 4, 2. Since it is rotated in sync, 4
A concave or convex pattern 1' processed at a constant pitch on the outer circumferential surface of the rolls 1, 1... is a convex or concave pattern b opposite to the pattern on the thin line a, as shown in enlarged detail in Fig. 6. As shown in the figure, the thin wire is continuously processed and formed at a constant pitch in the length direction. In this case, each roll 1 meshes with each gear 2 and a gear 4 arranged at intervals in the length direction of the wire material to be processed, and is coaxial with the gear 4.
These gears 2 and 4 and bevel gears 5, 5 are fixed at their respective relative positions at a 90 degree phase angle due to the meshing of the adjacent bevel gears 5, 5...
Since the rolls are rotated in synchronization through the meshing of the rolls, a constant phase shift of the pattern pitches provided on each roll is maintained without causing any play in the rolls 1 or slips with the thin wire. As shown in Figure 6, the irregularly shaped parts (concave pattern parts) on adjacent irregularly shaped lines (in the axial direction) on the surface of the thin wire formed by the roll are shifted in the same direction by P/4 of the irregularly shaped pitch P on the irregularly shaped line. A deformed wire is manufactured by continuously forming four concave patterns in the longitudinal direction of the thin wire surface.

The pattern processed into the thin wire a, for example, a concave pattern, always has a constant pitch in the longitudinal direction of the thin wire by the roll tuning mechanism 12, and its depth becomes shallow due to wear of the roll 1, but the roll lowering mechanism 19 By pushing forward the rolling down screw 18, the roll 1 is rotated through the frame 7 about the support pin 9 and rolled down, and can be maintained at a desired constant depth.

Further, due to the operation of the reduction screw 18,
Each roll 1 is rotated through the frame 7 with the support pin 9 as a fulcrum, and the gap 20 formed between the rolls 1 can be arbitrarily adjusted to match the thickness of the thin wire. At this time, the bevel gears 5, 5 also move at the same time. However, as shown in Fig. 4, the positional relationship between the roll 1, support pin 9, and bevel gear 5 is made into a right-angled triangle or a shape close to a right-angled triangle, and the bevel gear is placed at the right angle part, so that the gap formed by the rolls is Mutual bevel gears 5, 5, 5, 5 due to two-dimensional movement of bevel gears 5, 5 that occurs when changing
Since it is designed to minimize the increase or decrease in the crushing of the bevel gears, it is possible to adjust the gap formed by each of the four rolls without causing problems with the mutual meshing of the bevel gears. (4~10mm
φ), a convex or concave pattern b can be continuously formed in a predetermined arrangement in the length direction of the thin wire.

FIG. 5 shows a modification of a part of the present invention and four rolls 1.
This shows another embodiment in which the roll 1 is mounted as a drive type, and a bearing stand 22 is provided on one side of the support pin center of one of the frames 7 on which the roll 1 is mounted, and a chain rotated by a motor 23 is attached to the bearing stand. The chain 25 is connected to the chain wheel 24 by supporting the wheel 24 and extending the shafts 6 of the gear 4 and bevel gears 5 and 5 on the same frame 7 to one side.
A chain wheel 26 is provided to drive and rotate a set of gears 4 and bevel gears 5, 5. The operation is the same as described above, except that all the rolls are driven from the gear shaft 6 through the mutually meshing gear 4 and the bevel gears 5, 5 to apply advancing force to the thin wire. A thin wire is clamped and pressed by the rolls 1, and a convex or concave pattern opposite to the concave or convex pattern processed on the outer peripheral surface of the roll is arranged on the surface of the thin wire, for example, a concave pattern b. This method allows the thin wire to run while being accurately processed and formed at a constant pitch without overlapping the thin wire at the same cross-sectional location, and it is possible to manufacture irregularly shaped wires in the same way as described above.

In the above example, the manufacturing of a deformed wire in which four consecutive convex or concave patterns are processed on the surface of a thin wire was explained. By using a roll that has been processed, it is possible to manufacture a deformed wire in which one to a maximum of four convex or concave patterns are continuously processed in the longitudinal direction on the surface of the fine wire.

As explained above, according to the device of the present invention,
The gap through which the thin wire passes is formed using a plurality of combined rolls, but unlike conventional rolls where the rolls are free from each other and rotate freely due to the frictional force with the thin wire, a concave shape is formed on the outer peripheral surface. Alternatively, each roll having a convex pattern processed thereon may be placed in a position different from the roll arrangement, with a gear provided on the side of each roll, a gear meshing with this gear, and a bevel gear adjacent to each other on all sides being concentric. Since a roll synchronization mechanism is provided that is fixed at a relative position via an installed gear device and interlocks with each other via these gears, there is no play between the rolls or out of phase with each other, and the rolls are It is possible to continuously form a convex or concave pattern, for example, a convex or concave pattern at a constant pitch on the surface of the thin wire, which is the opposite of the processed pattern, and to define one to four convex or concave patterns in the longitudinal direction of the fine wire surface. Therefore, the processed part of the thin wire is constant in any cross section in the longitudinal direction of the thin wire, and the mechanical strength in the longitudinal direction of the thin wire is It is possible to manufacture deformed wires of good quality without certain variations.

In addition, each roll used to process patterns on fine wire is attached to a frame that is rotatably attached to the four sides of the stand body with support pins around the wire to be processed, and a roll-down mechanism that moves the tip of the frame in a radial direction.
By rotating each roll using the support pin as a fulcrum, the wire passing gap formed by each roll can be expanded or reduced, and at this time, the adjacent bevel gears on all four sides are also rotated using the support pin as a fulcrum. At the same time, since the bevel gear is installed close to the fulcrum side, it is possible to keep the fluctuation of the interlocking bevel gear to a minimum, and even when changing the wire diameter, smooth gear transmission is possible, and the wire material to be processed is The range that can accommodate changes in the size of the roll can be expanded, and unlike conventional devices that adjust the roll gap by moving the rolls forward and backward vertically and horizontally, the bumps are large, causing damage to gears, and the adjustment range of the roll gap is narrow. In comparison, there is a great effect that uneven patterns can be easily formed on several kinds of thin wires of different thicknesses using the same roll by using the advancing force of the wire rod or the drive of the rolls. In addition, even if the depth of the processed pattern (or the height of the convex portion) becomes shallow as the pattern on the roll surface wears, it can be easily adjusted and a pattern of a constant depth can always be added, so it is possible to add a pattern with a constant depth. The disadvantage of having to replace the roll each time the wire diameter changes or the roll pattern wears out is improved, the roll life can be increased, and the number of rolls to be owned can be reduced, resulting in economic efficiency and processing. It has excellent characteristics in terms of performance and quality improvement.
