Figure 4a is a front view in a state where the processing blade of the spiral machining of the present invention is narrowed, Figure 4b is a plan view according to Figure 4a, the locking groove of the processing blade 32 installed in the center of the body 34 of the spiral steel processing portion 30 As the key 308 flows in the direction of the arrow by the spring 306 of the fixing pin 305 in the state in which the locking part 308a of the key 308 of the control unit 300 is inserted into the 32a. By moving the machining blade 32 in the direction of the arrow, the machining blade 32 in which the outer inclined surfaces are engaged with each other is narrowed, and the key 308 is tapered of the guide jaw 302 of the control key 304. It is shown in the horizontal portion is not supported.

FIG. 5A is a front view of the spiral blade of the present invention in a state where the cutting edge is opened, and FIG. 5B is a plan view according to FIG. 5A, wherein the key 308 is tapered from the guide jaw 302 of the control key 304. When the tapered portion is slid to the finished position, the cutting edge 32, which has been narrowed by engaging the outer surfaces thereof, is shown to be completely opened.

At this time, the tapered guide jaw 302 portion of the control key 304 is to play a significant role to actually determine the angle of inclination of the rebar.

The working relationship of the present invention configured as described above will be described in more detail with reference to the accompanying drawings.

First, after inserting the insertion hole 152 of the guide holder 154 of the fixing portion 15 to the end of the reinforcing bar to process the spiral connection portion and drives the forward and reverse motor 14 by the conventional gear transmission A plurality of fixing pieces 156 that are transmitted with power are tightened to fix the rebar.

When the fixing of the reinforcing bar by the fixing part 15 is completed, the forward and backward levers 18 engaged with the forward and backward rack gears 35a of the support block 35 are rotated on the inside of the upper frame 19. Along with the support frame 20 installed on the guide rod 16, the processing unit 40 is advanced, and at this time, the locking rib 22 formed as one end of the support frame 20 is rotated by the lever 162. The stepped groove 164 is introduced into the step of the processing length adjusting unit 160. That is, as the spiral processing portion 30 forms a spiral in the reinforcing bar as it is drawn in from the outside of the stepped groove 164 of the processing depth adjusting unit 160, stepwise from the outer circumferential surface of the reinforcing bar to step inward. It can be processed.

When the advance of the processing unit 40 is completed as described above, as the drive motor 30a installed in the support frame 20 is driven to rotate the spiral processing unit 30 installed at the tip and the spiral processing unit 30 is rotated. The outer circumferential surface of the rebar is processed by the processing blade 31 of the processing blade 32 installed to flow organically by the control unit 300 to the center of the body 34.

At this time, the machining blade 32 is coupled to the fixing pin 305 in relation to the key 308 is located at the position formed in the horizontal line on the guide jaw 302 of the control key 304 as shown in FIG. The outer peripheral surface of the rebar is machined as the cutting edge 32 acts in the same direction as the arrow direction due to the expansion force that the spring 306 is intended to expand to narrow the plurality of cutting edges 32 on which the outer inclined surfaces abut. Will be done.

As the processing starts, the processing of the spiral connecting portion to be processed is sequentially performed by drawing the processing part 40 sequentially in the stepped groove 164 of the spiral depth adjusting part 160 using the front and rear advance lever 18. It's done.

That is, when the key 308, which was positioned in the horizontal direction of the guide jaw 302 of the control key 304, is positioned at the tapered position of the guide jaw 302, this portion becomes a sharp end of the spiral. When the key 308 is positioned to the end position of the tapered portion while sliding to the tapered surface, the machining blade 32 is gradually opened to form an inclined spiral connection on the rebar. At this time, the tapered portion formed in the guide jaw 302 of the control key 304 is to achieve the actual angle of inclination of the spiral connection of the reinforcing bar.

As described above, when the processing blade 32 of the body 34 is opened, the processing of the spiral connecting portion of the reinforcing bar is completed. At this time, the driving of the driving motor 30a is stopped, and the operator rotates the forward and backward lever 18 again. After reversing the processing unit 40 to the rear, the reinforcing bar fixed to the fixing unit 15 is removed and the unprocessed reinforcing bar may be continuously processed in the above-described order.

On the other hand, if you want to form a long length of the spiral connection in the process of processing the spiral connection as described above, the rack is installed on the support frame 20 by rotating the spiral length control lever 17 in the state of FIG. As the rotary gear installed on the shaft of the spiral length adjusting lever 17 engaged with the gear 24 is rotated, only the spiral processing part 30 is advanced back and forth on the supporting frame 20 and the supporting block 35 to adjust the length of the spiral connecting portion. It can be.

As described above, the present invention can improve the tensile strength by processing the inclined spiral connection part precisely at the connection part of the reinforcing bar as well as the effect of easily processing the spiral connection part in the rebar by directly handling it in the field. To have.

In addition, it is possible to form a precise spiral connection to the rebar, there is no need to import the rebar used by importing from the conventional foreign companies, thereby having the effect of preventing foreign currency loss due to the import of the rebar.
