JPS5829172B2 - Wire rod scale peeling device using tensile force - Google Patents

Description

DETAILED DESCRIPTION OF THE INVENTION The present invention continuously scales the scale of the wire rod, for example, by applying a cyclically varying tensile force to the wire rod in a predetermined section during the feeding process of the wire rod. (This relates to a wire rod scale peeling device that uses tensile force to cause peeling.)

Conventionally, methods for removing scale from wire rods include pickling using hydrochloric acid or sulfuric acid solution, the so-called bending method in which the wire rod is bent by passing it between a plurality of vertically displaced rollers, or A shot blasting method in which steel balls, glass beads, etc. are radiated onto the wire externally,
Alternatively, there are methods that use a combination of these, but in the first method, the waste liquid after use may cause pollution, and in reality, it is difficult to remove scale sufficiently with methods other than the second.

The present invention aims to provide an efficient scale removal device that eliminates the drawbacks of conventional scale removal.

The present invention will be explained according to Embodiment 0 shown in FIGS. 1 to 4C.

In FIG. 1, 3 and 1 indicate the payoff stand.

The wire rod W from the payoff stand 1 is fed in the direction of the arrow by the feed roller 2 while maintaining a predetermined tension state.
It is wound up by a winding machine 8.

In front of the feed roller 2 in the feed direction is a rotating body 3 configured to feed the wire in a state where the wire is wound one or more turns around a predetermined peripheral surface of the wire winding section. A rotating mechanism 5 is disposed in front, and a rotating body 7 having the same structure as the rotating body 3 is disposed in front of the rotating mechanism 5 in the feeding direction.

As the rotating body 3.7, for example, a known cab stern as shown in FIG. 1 can be used.

The cab stern 3 includes a wire rod winding section 31 having a tapered outer peripheral surface and a wire rod guide 32 provided at a position facing a predetermined outer peripheral surface of the winding section 31.

The take-up part 31 self-rotates in accordance with the rotation of a rotating shaft 33 pivotally connected thereto.

The cab stern 7 also has exactly the same configuration as the cab stern 3.

The rotating mechanism 5 is as shown in Fig. 1←Yohi Fig. 2.
For example, a known planetary gear system can be used.

That is, the planetary gear 53 is configured to rotate and revolve between the inner south gear 51 and the sun gear 52, and the rotation center C of the sun gear 52 is eccentric from the wire feed direction line, and the rotation of the planetary gear 53 is A rotation guide 531 consisting of a through hole is provided at the center of the shaft, and the wire W is passed through the rotation guide 531. By rotating the sun gear 52 in a predetermined direction, the planetary gear 53 rotates eight times, and the kite rotates. 531 and revolves around the rotation center C of the sun gear 52.

In other words, 54 is a connecting member that rotatably connects the respective rotating shafts of the sun gear 52 and the planetary gear 53.

In such a configuration, in order to feed the wire W at a predetermined speed by the feed roller 27 rotor 3, rotation mechanism 5, and rotor 7, each is set to rotate at a predetermined rotation speed.

The wire from the payoff stand 1 is passed through the feed roller 2 and wound one or more turns around the tapered wire winding part 31 of the rotating body 3 by the wire guide 32, and then is wound as the rotating body 3 rotates by itself. , guided by the wire guide 34 and sent to the rotation mechanism 5.

After passing through the rotating guide 53, the wire W passes through the wire guide 72 and is wound into a chi-shaped wire winding 71 of the rotating body 7.
After being wound one or more times around the body, it is wound up by a winding machine 8 as the rotating body 7 rotates by itself.

The sun gear 5 of the rotating mechanism 5 is used for the wire feeding process.
20, the rotation guide 531 rotates on its own axis and rotates about the rotation center C of the sun gear 52 in a plane perpendicular to the wire feeding direction.

As a result, a bowing force that cyclically changes depending on the position of the rotating guide 53 with respect to the wire feeding direction line is applied to the wire between the rotating bodies 3 and 7.

As mentioned above, the wire rod feeding process Kt, -, the wire rod W
The wire rod guides 32 and 72 are configured to send the predetermined external material of the rotating bodies 3 and 7 in one or more wound state, so that the rotating guide 5
3 rotates, the rotating body 3 and the rotating mechanism 52 rotate
The rotating body 5 applies a cyclically varying tensile force to the i-wire between the I-wire and the rotating body 7, and the scale of the wire is effectively peeled off.

Although it has peeled off, the fine scale that remains on the surface of the wire rod W is also removed during the wire feeding process using a fine scale removal device 4 consisting of a rotating flan or a known gas or liquid injector. be done.

In this way, the wire rod is wound up by the winder 8 after the scale has been sufficiently removed.

A second embodiment of the invention is shown in FIG.

This embodiment is arranged between a plurality of adjacent feed rollers 2 and a rotating body 7 having the same configuration as the rotating body 7 shown in FIG. 1, and having the same configuration as the rotating body 3 shown in FIG. As shown in FIGS. 4a and 4b, the rotating body 3 is continuously displaced by a predetermined amount in the wire feeding direction or perpendicular to the wire feeding direction using a reciprocating mechanism such as cylinder mechanisms S and S. This is an example in which a saw-shaped cyclically changing tensile force is applied to the wire between the feed roller 2 and the rotating body 7.

Although not shown in FIG. 3, a wire guide having the same structure as the wire guide 34 shown in FIG. 1 is arranged in front of the rotating body 3 in the feeding direction.

Further, as shown in FIG. 4C, a similar tensile force can be obtained by a continuous circular motion resulting from a composite motion of the wire feeding direction and a direction perpendicular to the wire feeding direction.

As can be seen in the above-mentioned actual flowcharts, according to the present invention, it is possible to effectively remove scale from wire rods.

The following are some of the results of experiments conducted by the inventor regarding the present invention.

(1) Test wire diameter: 10 mm, 10 types, 533C (2) According to the present invention, a tensile force of 1 was applied to the wire, and the peeling status of the scale was investigated with respect to the total amount of strain (elastic strain + plastic strain).

As is clear from the above experimental results, according to the present invention,
Compared to the conventional mechanical peeling method, it is possible to remove scale very efficiently, and unlike the 19 pickling method, it is possible to remove scale without causing any pollution problems.
