BACKGROUND OF THE INVENTION Field of the Invention [0001] The present invention relates to a knuckle processing apparatus for deformed reinforcing bars for rolling rolls, and more particularly, to a processing apparatus for forming a part corresponding to the section of a deformed reinforcing bar in a mold of a rolling roll for manufacturing a deformed reinforcing bar.

The deformed reinforcing bar is formed by protruding ribs along the longitudinal direction of the reinforcing bar on the surface of the reinforcing bar and a node formed in the vertical or inclined direction to increase the bonding force between the reinforcing bar and the concrete.

The ribs and nodes of the deformed steel bar can be formed by processing grooves of a shape corresponding to the ribs and bars on the inner circumferential surface of the ball formed on the surface of the rolling roll for rolling the steel bars.

The said node is processed by rotating the rolling roll in which the ball was formed along the circumferential direction on the surface, and entering the bite into the inside of the ball to rotate the bite in the direction orthogonal to the rotation axis of the rolling roll.

For reference, Korean Unexamined Utility Model No. 20-1995-0029686 describes a technique for processing a ball mold on the surface of a rolling roll using a lathe.

An object of the present invention is to provide a node processing apparatus of a reinforcing bar for rolled reinforcing bars for rolling rolls, which is capable of precisely processing the node shape by accurately measuring the depth of the node in reworking a ball-shaped node for reuse of a rolling roll. have.

The present invention for achieving the above object,

In addition, the electric wire is connected to both ends of the power source, characterized in that both wires are connected to the rotating surface of the bite holder and the rolling roll via a brush.

In addition, the power source is characterized in that a small capacity power source constituted by a battery.

In addition, the electronic control unit is characterized in that the electronic control unit for controlling the operation of the rotary device of the rolling roll and the tool post on which the bite holder is mounted.

The notification device may include a lamp that is turned on by the electronic control unit and a speaker that generates a notification sound.

In addition, the electronic control unit is characterized in that the forward operation of the tool stand is stopped at the moment when the energization signal is generated.

According to the present invention as described above, it is possible to accurately measure the node depth of the rolled roll to be reused, it is possible to process the new node to the correct depth.

Therefore, the rolling reduction of the upper and lower rolls does not cause a difference, thereby preventing bending of the reinforcing bar when rolling the reinforcing bar, thereby improving productivity.

In addition, it is possible to stop the advancing of the tool bar at the moment when the inner surface of the bite and the node contact, it is possible to prevent the breakage of the bite and the suction formed on the inner surface of the node.

1 is a block diagram of a node processing apparatus of a reinforcing bar for rolling rolls according to the present invention,
Figure 2 is an enlarged view of the main portion of the node processing apparatus of the reinforcing steel bar for rolling rolls according to the present invention.

Hereinafter, with reference to the accompanying drawings, the present invention will be described in detail.

As shown in Figure 1 and 2, the apparatus for processing a portion corresponding to the section of the reinforcing bar (hereinafter referred to as 'node') on the rolling roll is a tool post 10 that can move linearly back and forth and left and right ), A chuck 11 installed and rotated on the upper surface of the tool rest 10, a bite holder 12 fixed to the chuck 11, and a bite inserted radially into the bite holder 12. (13).

In the processing apparatus, the support part 20 is formed on the tool rest 10, and the center 22 is vertically downwardly mounted on the head part 21 of the support part 20. By minimizing the upper end of the bite holder 12 (rotation is possible), vibration is minimized during rotation cutting of the bite 13.

On the other hand, as shown, in front of the tool post 10 is equipped with a rolling roll rotating device 30 that can be rotated in a supported state by mounting a rolling roll 31 to be processed.

Since the rolling roll 31 is to be reused, the shape of the mold 31a and the previously used segment 31b remain before the reworking of the segment (that is, the additional processing).

On the other hand, the present invention includes a power source 50, the anode of which is connected to the bite holder 12 and the rolling roll 31, the bite holder 12, the rolling roll 31 and the power source 50 An electricity supply detecting sensor 60 for detecting whether electricity is supplied to the electric circuit, an electronic control unit 70 for operating the notification device 80 when the electricity supply signal is received from the electricity detecting sensor 60, and the notification device 80. ).

2 is a front view of the bite holder 12 and a plan view of a state in which the bite holder 12 is inserted into the mold 31a of the rolling roll 31 in order to facilitate the understanding of the present invention. One side of the (50), that is, the portion connected to the byte holder 12 is shown as being connected to the front view of the byte holder 12.

Although the power source 50 is indicated as a DC power source, not only a DC power source but also an AC power source may be used.

Since the power source 50 is not a power source for driving the device but a signal generation power capable of detecting the flow of current, the power source 50 is configured to have a weak voltage separately from the driving power source (for example, 1.5 to 6V, That is, it is a power supply that can be configured even with ordinary batteries.)

Both ends of the power source 50 are connected to the bite holder 12 side and the rolling roll 31 side, respectively.

Since the bite holder 12 and the rolling roll 31 are both rotating bodies, brushes 41 and 42 are provided at the ends of the connection wires so that the bite holder 12 and the rolling roll 31 are rotated. It is configured to maintain state.

As shown, the bite holder 12 side brush 41 may be installed such that the bite holder 12 is in contact with the side of the fixed chuck 11, and the rolling roll 31 side brush 42 ) May be installed to contact the side end surface or the circumferential surface of the rolling roll (31).

The energization detecting sensor 60 is installed on a wire connected to the power source 50, detects when a current flows in the wire, generates an energization signal, and transmits it to the electronic control unit 70.

The electronic control unit 70 is to operate the notification device 80 when the energization signal is input from the energization detection sensor 60, may be configured as a separate device, but the electronic control unit of the node processing device It is desirable to share.

The notification device 80 is operated and controlled by the electronic control unit 70 and includes an electric circuit including a power supply 50, a bite holder 12, and a rolling roll 31 having a lamp and a speaker. When the lamp is turned on and a notification sound is generated through the speaker so that the operator can recognize the energized state.

The operation and effects of the present invention will now be described.

In order to rework the node 31b in the mold 31a of the rolling roll 31, it is necessary to accurately know the depth of the previously formed, that is, the previously used node 31b.

Only by knowing the depth of the remaining nodes 31b after using it previously can you know how much more processing should be carried out to form the new nodes 31b, which will allow you to process the new nodes 31b to the correct depth. Because.

That is, the present invention is to reduce the amount of processing for forming a new node by forming a new node by performing additional processing to the existing node when reusing the rolling roll 31.

First, the tool holder 10 is operated to move the bite holder 12 to a position coinciding with the center (CC line) of the ball 31a, and then the bite holder 12 is advanced to the ball 31a. Inside).

Once the bite holder 12 has entered the ball 31a, in particular from the time when the bite 13 has entered the bar 31b and the end position of the bite 13 is not observed visually. Fine control of the operation of the tool post 10 allows the bite holder 12 to more precisely advance the bite 13 into the inside of the segment 31b.

If the advancing continues, the bite 13 eventually comes into contact with the inner wall surface of the node 31b. At this moment, the electric circuit including the power source 50, the bite holder 12, and the rolling roll 31 Is formed. That is, current of the power source 50 flows through the bite holder 12 and the rolling roll 31.

When the current flows in the electric circuit including the bite holder 12 and the rolling roll 31 as described above, the conduction detection sensor 60 detects this to generate an conduction signal, the electronic control unit received the conduction signal 70 operates the lamp and the speaker to notify the operator and stores the measured depth of the node 31b in the storage device.

The reference position of the byte holder 12 is set in advance in the electronic control unit 70, and the node 31b is moved by the distance that the byte holder 12 has moved from the reference position to the time point at which the energization signal is generated. Can calculate the current depth of.

That is, since the distance from the reference point to the inner wall of the current node can be known, it is possible to know exactly how much further processing is required for forming a new node.

Therefore, even if the degree of wear of the node is different for each rolling roll to be recycled, it is possible to accurately measure the depth of the current node to the precise additional processing to the depth of the node to be molded.

Therefore, the nodes of the upper rolling roll and the lower rolling roll can be processed to the same depth.

Therefore, the rolling reduction amount of the upper rolling roll and the lower rolling roll is the same when rolling the rebar, thereby preventing the rebar from bending upward or downward while exiting between the upper and lower rolling rolls, and proceeds straight to the temp core. It can be inserted.

Therefore, productivity can be improved by being able to prevent operation stop during the progress of the rebar rolling process.

In addition, the moment the energization signal is generated, the electronic control unit 70 can stop the forward operation of the tool post 10. That is, the advance of the tool post 10 can be stopped by a method other than manual operation by the operator. Therefore, since the advance of the tool post 10 does not progress excessively, the damage of the bite 13 and the damage of the inner surface of the node 31b can be prevented.

On the other hand, if the notification device 80 does not exist, since visual observation is impossible after the end of the bite 13 enters the inside of the node 31b, the advance control of the bite holder 12 may be accurately performed. Since the bite 13 collides with the inner wall surface of the node 31b due to excessive advancement, the bite 13 is broken and a scratch is generated on the inner surface of the node 31b. Since the contact moment between the inner surface of the 31b and the bite 13 can be accurately known, it is possible to prevent the excessive advance of the bite 13, thereby preventing the breakage of the bite 13 and the occurrence of scratches on the inner surface of the bite 31b. Can be.
