Abstract

PURPOSE:To obtain a working device that works continuous recessed or projected patterns accurately on a fine irregular shape wire, by fixing four rolls that form gaps disposed in four sides and through which a fine wire to be worked passes to respective relative positions by engagement of gears and changing and adjusting the gaps of rolls. CONSTITUTION:A fine wire 1 to be worked is supplid from the direction of the arrow or the opposite direction and passed through gaps 20 having preset sizes and formed by four rolls 1 facing to each other vertically and horizontally. When the fine wire (a) passes through rolls 1, four rolls 1 are rotated. The rotation of all rolls 1 is synchronized by mutually engaging bevel gears 5, 5 and gears 4, 2 and recessed or projected pattern 1' are formed at a fixed pitch by the outer peripheral faces of rolls 1 on the fine wire (a). At this time, phase angles of 90 deg. are fixed at respective relative positions by engagement of gears, and rolls 1 rotate in interlocked states through the gears. Accordingly, an irregular shape wire on which four recessed patterns are continuously formed in the longitudinal direction is manufactured without generating a play in the rolls 1 and a slit with the fine wire (a).

Description

DETAILED DESCRIPTION OF THE INVENTION The present invention is used in the process of thinning (drawing) or straightening a 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 invention relates to an apparatus for processing a concave or concave continuous pattern on the surface of a thin line using a concave or convex pattern processed on a roll.

In the conventional processing device 1t of this type, a plurality of combined rolls are free from each other, and when a pattern is processed into a thin line, each of the rolls rotates freely, and the length direction of the thin line is determined in the 41y direction. It often happens that the thin wire is machined at the same position in the length direction instead of being processed at the same position, 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. was.

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.
Patterns are processed only on thin wires that are the same as the gap or slightly thicker, and each time the thickness of the thin wire to be processed changes, it is necessary to replace the roll with a roll that corresponds to that thickness. As the pattern wears away, the depth of the concave pattern processed into fine lines becomes shallower, and in order to process a pattern of a certain depth, it is necessary to replace the rolls. The life of the roll is short, etc.
There was a ton.

In order to improve these drawbacks, the present invention has seven rolls that are arranged in the same direction and that form gaps between the rolls through which the thin wire to be processed passes, and are fixed at their respective relative positions by meshing traps of gears. In addition, each roll is provided with a four-roll W4 mechanism in which the rolls are interlocked with each other via the gear, and the seven rolls freely form the above-mentioned gap approximately centered on the axis of each gear. It is equipped with a roll-down mechanism that rotates so that the width can be changed and adjusted, making it possible to accurately process concave or white continuous patterns into fine lines of varying thickness, and to maintain a constant pattern pitch and depth. The purpose is to provide a reliable one-shape wire processing equipment that can perform processing.

Hereinafter, one embodiment of the apparatus of the present invention will be described based on the drawings. The inside and outside of the wire are machined into a shape corresponding to the cross section of the thin wire so that the thin wire (a) of the wire to be processed is in contact with the thin wire (a) at a phase angle of 2a degrees. and a concave or convex pattern at a constant pitch on its surface.
A gear (2) is concentrically and integrally attached to the side of the roll with a shaft (3), a gear (4) that meshes with this gear (2), and a similar pond on the left and right of the shaft (3). A shaft (6) that is integrally fixed with a bevel gear (Fi) (5) that meshes with an umbrella # wheel.

A roll-down mechanism (oil is provided) is installed to set the roll (1) at a predetermined position via each frame (7) by attaching a roll-down screw (1 (to)) that moves f4 along 61.

Each roll (1) has a support pin y + of a respective frame (7)

This allows it to be changed to any size.

Also, when the roll (1) is rotated using the support bin (91) as a fulcrum, the umbrella l'4i4tun (5) (5) also moves at the same time, but the roll (support bin (9) and bevel gear (5) The positional relationship between the two is set as shown in Fig. 7, that is, a right triangle or a shape close to a right triangle. This can be handled by minimizing the increase or decrease in backlash of gears (5) and (5).

Although it is desirable that all seven rolls (1) have the same diameter, a diameter of W can be used within the range of the backlash 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 ra) of the wire to be processed is supplied from the direction of the arrow in FIG. Due to the advancing force of the thin wire, the wire passes through a gap (mu) of a preset size formed by a number of rolls (1) facing each other vertically and horizontally.

Thin wire (when the river passes along the roll (1), each 9
As the rolls (1) are rotated, all the rolls (1) are rotated in unison with each other by the bevel gear m (5) and the gears (4) and (2) that mesh with each other. Concave or convex patterns (lf is a concave or concave pattern (9) that is the opposite of the pattern on the thin line (a) ) are continuously processed and formed at a constant pitch in the length direction of the thin wire, as shown in the enlarged detailed view of Fig. Since they are fixed in position and rotated in synchrony in conjunction with each other via this mTtL, it is possible to avoid a certain phase shift in the pattern pitch provided on each roll without causing play in each roll (1) or slipping with the thin wire. As shown in FIG. 6, the interfacial portion (II
IJ-shaped pattern parts) are shifted in the same direction by 5-shaped pitch (P/4t of Pi) on the single-breasted wire, and a concave pattern of grooves is continuously processed in the longitudinal direction of the fine wire surface to produce a deformed wire. It is something.

The pattern processed into the thin wire ((1), for example, a concave pattern, is always at a constant pitch in the longitudinal direction of the thin wire due to the roll synchronization mechanism 1121, and the depth of the pattern is determined by the groove roll (1).
However, by pushing forward the roll-down screw 08 of the roll crown (sa9), the roll is rotated around the support pin (9) through the frame (7) and rolled down as desired. can be maintained at a constant depth.

The chain force is transmitted through the chain.
The gear set (4) and the bevel gears (5) (5) are configured to rotate and rotate. The only difference in its operation is that all the rolls are driven through one gear (gear (4) and bevel gear <5) that mesh with each other from 61 (5) to apply a advancing force to the thin wire. Then, the thin wire is pressed by ψ rolls of the same length, and a convex or concave pattern opposite to the concave or convex pattern processed on the outer surface of the roll is arranged on the surface of the fine wire. In this method, for example, the concave pattern (b) is accurately processed and formed on the same cross-sectional area of the thin wire at a constant pitch while the thin wire is run, and irregularly shaped wires can be manufactured in the same manner as described above.

The above example works! 11 Describes the production of irregularly shaped wires with a continuous pattern of convex or concave grooves formed on the surface of the wire.

As explained above, by using a roll processed with a concave or convex constant pitch l^ pattern on the desired roll among the seven σ-rules, it is possible to increase the number of grooves from 7 to the maximum groove in the longitudinal direction of the fine wire surface. It is possible to manufacture irregularly shaped wires with continuous convex or concave patterns.

1. As explained above, according to the device of the present invention, although a plurality of rolls are combined to form a gap through which a thin wire passes, the rolls are free from each other and friction with the thin wire is avoided, unlike in the past. Unlike the rolls that rotate freely due to force,
The rolls, which have concave or convex patterns on their outer circumferential surfaces, are fixed in relative positions via gears, and a synchronization mechanism that interlocks with each other via the gears is provided, so that play in each roll and W phase does not occur mutually, and it is possible to continuously form, for example, a convex or concave pattern on the fine wire surface at a constant pitch, which is opposite to the processed pattern of the roll. It is possible to process and form a convex or concave pattern with the highest grooves in a predetermined arrangement at an even pitch, and therefore the processing M of the thin wire is constant regardless of the cross section in the length direction of the thin wire. Therefore, it is possible to produce a deformed wire with good quality and a constant mechanical slackness in the longitudinal direction of the thin wire.

In addition, each roll has a roll-down mechanism that allows the passage gap of the wire rod formed by each roll to be adjusted, so the same roll can be used to create convex shapes on thin wires of several thicknesses. Alternatively, a concave pattern can be processed by the advancing force of a fine wire or the drive of a roll, and even when the pattern on the roll surface becomes worn, the depth of the processed pattern (or the height of the convex part) becomes shallower. Since the pattern can always be added to a constant depth by adjustment, the disadvantage of having to replace the roll every time the wire diameter changes or the roll pattern wears out is improved, and the life of the roll can be extended. It has features that are excellent in economy, processability, and quality improvement, such as being able to increase the number of rolls and requiring only a small number of rolls.
