Description

Rebar Bender {re-bar bander}

The present invention relates to a bending machine, and more particularly to a rebar bending machine for bending the rebar.

In general, the bending machine has a bearing (not shown) having a bearing inside the motor (not shown) and the rotating shaft 2 is installed therein as shown in FIG. 1, and a rotating shaft 2 Rotating plate (3) is coupled to the upper case 1 is installed on the upper case 1 and a plurality of coupling holes (3a) is formed on the upper surface and a plurality of small holes (3b) around the end is fastened to this operation pin (not shown) And a bending roller 4 coupled to the coupling hole 3a formed on the upper surface of the rotating plate 3, a guide roller 5 coupled to the rotating shaft 2 and installed on the rotating plate 3, and the rotating plate 3. It consists of a fixed block (6) provided on both sides of the feed roller (7) provided on the left side of the fixed block (6), a plurality of sensors (8) are installed around the rotating plate (3).

The conventional bending machine has a bending roller 4 in the coupling hole 3a of the upper rotating plate 3 of the case 1 coupled to the rotating shaft 2 rotated by a motor (not shown) inside the case 1. When the rotating plate 3 is rotated to be coupled, the bending roller 4 pushes one side of the reinforcing bar 9 introduced into the front thereof in the rotation direction of the rotating plate 3 to bend the reinforcing bar 9.

However, since the rotating plate 3 and the guide roller 5 are rotated as the rotating shaft 2 is rotated when the reinforcing bar 9 is bent, the bending roller 4 is rotated and the rotating plate 3 is rotated when the rotating plate 3 is rotated. The bending roller 4 coupled to the coupling hole 3a pushes one end of the reinforcing bar 9, at which time the rotational force of the guide roller 5 and the force of the bending roller 4 pushing the reinforcing bar 9 are applied. As a result, the reinforcing bar 9 comes out in the rotational direction of the rotating plate 3, thereby causing an error in the bending angle to bend the first reinforcing bar 9.

In addition, the bending radius of the reinforcing bar 9 could not be reduced because the reinforcing bar 9 was bent to a relatively large radius as much as the diameter of the guide roller 5 on the upper side of the rotating plate 3 when bending the reinforcing bar 9.

An object of the present invention for solving the above problems is to provide a reinforcing bar bending machine to prevent the error when bending the reinforcing bar, and to reduce the bending radius.

The present invention rebar bending machine for achieving the above object is provided with a rotating shaft and a rotating plate rotated by a motor inside the case, a guide roller coupled to the rotating shaft, and a bending roller coupled on the rotating plate, the guide roller And a reinforcing bar bending machine for bending reinforcing bars located between the rollers and the bending rollers, the splitting pins being fixedly installed at the center of the upper part of the rotating plate and having a split groove formed at the center of the reinforcing bars; A tripod installed on a fixed block on one side of the rotating plate, and having coupling holes formed at both ends thereof, and the other end fixing the split pin; It is characterized in that it is further provided with a fixed roller coupled to one side coupling hole of one end of the tripod to support the rebar.

Therefore, the reinforcing bar is bent in a state of being fixed to the tripod, the fixed roller, the split groove of the split pin, so the reinforcing bar is not separated or twisted in the rotational direction to prevent an error in the bending angle. After being fixed and supported in the fitted state, since the revolving plate and the bending roller are rotated to bend the rebar, the bending radius of the rebar can be minimized.

Specific features and advantages of the present invention will become more apparent from the following description with reference to the accompanying drawings.

Figure 2 is a plan view showing the present invention rebar bending machine, Figure 3 is a front view of Figure 2, the motor housing 11 is provided on one side inside the case 10, the bearing housing 13 having a bearing in the center thereof Is provided. Here, the motor shaft (11a) is coupled to the electric gear 12 and the bearing housing 13 is coupled to the bearing housing 13, the rotating shaft 15 is coupled to the bearing housing 13, the electric gear 12 And the interlocking gear 14 are connected to the shaft 16.

The upper part of the case 10 is provided with a rotating plate 17 which is coupled to the rotating shaft 15 and rotated, the rotating shaft 15 is coupled to a part of the lower side of the coupling hole 7a of the rotating plate 17, and the rotating plate 17. A plurality of coupling holes (17a) is formed on the upper surface of the coupling hole (17a) is coupled to the bending roller 18 for pushing and bending the reinforcing bar when the rotating plate 17 is rotated, and around the end of the rotating plate (17) A plurality of small holes 17b are formed to fasten the operation pins (not shown), and a plurality of sensors 19 are provided around the rotary plate 17 so that the operating pins contact the sensors 19 when the rotary plate 17 rotates. To stop the rotating plate 17.

This is when the reinforcing bar 26 is bent at a predetermined angle so that the reinforcing bar 26 has an acute angle or an obtuse angle when the operating pin is in contact with the sensor 19 to operate the motor 11. This stops the rotating plate 17 to bend the reinforcing bar 26 by a predetermined angle.

On both sides of the rotating plate 17, a fixed block 20 having a plurality of coupling holes 20a formed thereon is installed, and a feed roller 21 for transferring the reinforcing bars 26 is provided on the left side of the fixed block 20. It is provided.
