This paper relates to an automatic rebar bending machine for automatically bending aggregates such as rebar and pipes (hereinafter referred to as reinforcing bars) in various construction sites and construction sites. It is a very reasonable improvement, so that it is possible to automatically bend the reinforcing bar required in large quantities in the construction site or construction site, so that it can be used very practically.

Conventionally, a number of rebar bending machines that can be used in various construction sites or construction sites have been drawn out and put into practical use. However, these conventional rebar bending machines are bulky and heavy, so manpower is excessive during transportation and installation, and bending of rebars is by power. Slip phenomenon occurred in the rebar which was hung between the bending roller and the center roller, and the bending position of the rebar was very difficult.

In addition, when one rebar bending angle is different, it is necessary to turn the handle manually to displace the bending angle. Therefore, the bending efficiency of the rebar is extremely low, and the reinforcing bar supported by the central roller and the bending roller is bent and returned to its original position. The city had to be reversed with a separate power source, so the power was excessive, the operating range was high, and the failure rate was high, and the bending radius of the rebar was limited, so it was impossible to bend the relatively large round bars. .

Especially, the scale should not be smoothly discharged during the bending work of the rebar, but the scale should be cleaned. However, in the light of the realistic working conditions, the cleaning work is not performed properly, resulting in excessive load on the rebar bending machine. There was a pedan and when bending the reinforcing bar, the rear of the reinforcing bar between the center roller and the bending roller was drooped by its own weight. Therefore, the manpower is excessive and accordingly, the reinforcing bar bending work takes a lot of effort, and the work efficiency is low.

This proposal was devised to solve all the problems of the conventional rebar bending machine as described above. That is, a compact and lightweight rebar bending machine that can be used as a household 220V single-phase electric machine is easily moved to various construction sites or construction sites. By changing the bending angle or bending radius arbitrarily and easily, it ensures the maximum bending efficiency of the rebar and minimizes the power consumption, thereby contributing to the cost reduction and using the pedestal of the rebar bending machine to fix the rebar and bending It is easy to supply the roller to streamline the bending work of the reinforcing bar, and the gear folding method is adopted to prevent unnecessary operation of the handle for adjusting the bending angle by external force during the bending work of the rebar. To prevent dislocations that are displaced A can be accurately folded to be compliant and which absorbs impact of the group hameuroseo chakseol a buffer material capable of preventing the impact of the return rollers of the bending operation after the bending of the reinforcing reinforcement bending able to extend the service life.

In addition, the upper outer circumference of the air is formed with a projection to prevent the end of the scale falling directly during operation to reduce the occurrence of breakage or failure of the machine, so it can be used reasonably as a rebar bending machine in various construction sites or construction sites It will be described in detail with reference to the accompanying drawings as follows.

The power of the motor 800 is transmitted to the pinion 803 of the shaft 802 via a series of reduction gears 801 to drive the air gear 502, so that the upper center roller 303 and the bending roller 300 and In the configuration of a conventional reinforcing bar bending machine 1, which allows the various reinforcing bars 900 hung on the support 200, the bottom plate 3, the bottom plate 3 is a fixed plate combined with a cushioning material 510 made of urethane or the like ( 509 is fixed to the top of the outer periphery of the air gear 502 fixed to the rotating shaft tube 503 to form a projection 507, the inner end of the T-shaped buffer wall 508 protrudes the air gear 502 The bottom surface of the space portion 511 is formed for the purpose of weight reduction.

And the upper portion of the central shaft tube 500 to which the central shaft 101 of the fixed mold 100 is coupled to the hook rod 108 in the longitudinal direction to the bottom of the central axis 101 of the fixed mold 100 The mouth 103 is caught and the fixing pin 106 is coupled to an outer end side of the central shaft tube 500 of the upper plate 3 so as to be coupled to the bottom recess recess 104 of the fixing mold 100.

In addition, a body tooth 206 is formed in one shaft portion of the upper plate 3, and the reinforcement 900 is grounded to the ground surface 201 by fastening the coupling bolt 205 by the gear 204 of the support 200 and the long hole 9203. Grounding to be bent by the movement of the bending roller 300, and if necessary, remove the coupling bolt 205 from the long hole 203 by turning the direction of the support 200 reversely, the tooth 204 is the body gear 206 By recombining by), the reinforcing bar 900 is hung on the ground rod 202, and a separate auxiliary cover 306 is overlaid on the upper portion of the central axis 101 and the moving shaft 302 to be relatively along the round part 308. Allows bending of large round rebar 900.

Meanwhile, at one end of the rotating shaft tube 503, the chain 600 connected to the chain connecting pin 601 is wound on the roller 602 built on the base 2, and connected to the connecting pieces 603 and 604 connected to the spring 605. By the elastic adjustment bolt 606 coupled to the support 207 of the base (2) to adjust the tension of the spring 605 and the end of the helical gear 504 built on the central shaft pipe 500 The proximity switch 512 is installed to control the rotation of the standby gear 502, and the other end of the shaft 701 of the one-point bending handle 10 while sliding the helical gear 505 acting on the one-point bending handle 10 Closed end where the one-point bending handle 10 is arbitrarily operated by installing the gear 700 and the clasp 702 to be grounded to the same type tooth 209 grounded on the base 2 while being installed in the spring 703. To prevent.

In addition, a limit switch 208 is installed on the side base 2 of the air gear 502 built on the bottom surface of the upper plate 3 to control the rotation angle of the air gear 502, thereby preventing overload of the iron bending machine 1. By reducing the occurrence rate of the failure by combining a separate scrap discharge pipe 506 on the bottom of the air 502, the scrap generated when bending the reinforcement (900) falls to the bottom to fall naturally according to the rotation of the air 502 The various control boxes inside the base (2) are made of aluminum casting for weight reduction.

And both ends of the pedestal 4 of the reinforcing bar bending machine 1 is formed with a bearing portion 401, respectively, to build a conventional unit conveyor roller 403 to be used for the reinforcement settle supply and reducer 801 and A clutch 809 is installed on the bottom of the motor 800 to control the power of the motor 800, and the bending angle is controlled by the one-point bending handle 10 and the two-point bending handle 11 on the front control panel. By connecting the 1.2 point foot switch (12) (13) that can be adjusted to be able to bend the two angles of the rebar.

This proposal as described above is to be used to supply the construction materials by bending at a certain angle of rebar (900) or pipe (901) used in large quantities in various construction sites, construction sites, etc. First, the rebar (900) In the case of bending, push the one-point bending handle 10 attached to the control panel in the front to the inside of the base 2, and when the gear 700 of the shaft bar 701 grounded at the base 209 is separated, the inner spring When the 703 is compressed and the handle 10 is released by turning the one-point bending handle 10 by a desired angle, the two helical gears 504 are restrained by the restoring force of the spring 703 installed on the latch 702 and the shaft 701. Since 505 is rotated to each other, it is possible to adjust the bending angle of the desired reinforcement (900).

When the bending angle of the desired reinforcement (900) is adjusted as described above, the bending roller (300) and the support (200) when the reinforcement (900) is hung in the hanging groove (102) of the fixed mold (100) and the central axis (101). When the reinforcement 900 is hung on the ground surface 201 of FIG. 1 and the one-point foot switch 12 is operated, the power drives the motor 800 to pass through the series of reducers 801 to pinion 803 of the shaft 802. Driving the ground gear 502 grounded to the pinion 803, the spring 605 connected to the chain 600 on one side is extended, and the bending of the moving shaft 302 installed on the gear 502 is extended. As the roller 300 moves along the moving groove 301, the fixed mold 100, the bending roller 300, and the reinforcing steel 900 hung on the ground surface 201 of the support 200 are bent at an angle. Once the desired angle is bent and adjusted with the one-point bending handle 10, the control is made by the proximity switch 512. The root 900 is bent and continuously the standby gear 502 has to be moved to its original position. At this time, under the control of the proximity switch 512 without a separate power source, the clutch 809 at the bottom of the reducer 801 operates to power Since the intermittent chain is connected to the chain connecting pin 601 of the rotating shaft plate 503 arranged in the air gear 502, the chain 600 is installed in the spring 605, and the roller 600 is pulled back to its original position by the restoring force of the spring 605. Since it is pulled backward in the state wound around 602, the end gear 502 fixed to the rotary shaft tube 503 is to be returned to its original position with respect to the central shaft tube 500.

At this time, when the restoring force of the spring 605 is excessively generated, the contraction wall 508 protruding from the upper portion of the air gear 502 hits the shock absorbing material 510 of the fixed plate 509 fixed to the upper plate 3. This is absorbed as much as possible and the lower central axis 101 of the fixed mold 100 is formed in the concave indentation 103 to prevent the phenomenon of free rotation by hanging on the locking rod 108 and the locking groove of the fixed mold (100) 102) Since the recessed grooves 105 recessed at both ends are prevented from being pulled by the rebar 900 according to the movement of the bending roller 300 when the rebar 900 is bent, the bending position or angle of the rebar 900 is adjusted. The fixed pin 106 that is precisely controlled and fixed to the outer end of the central shaft 101 is fixed by coinciding with the recessed grooves 104 on both sides of the bottom surface of the fixing mold 100, thereby being firmly fixed during bending of the rebar 900. .

On the other hand, when the original position restoring force of the air gear 502 decreases during the use of the reinforcing bar bending machine 1 of the present invention, the support 207 is tightened by tightening the elastic adjustment bolt 606 inserted into the support 207 of the base 2. When the elasticity of the spring 605 is increased by decreasing the elastic force of the spring 605 during use, it is possible to always maintain the correct tension.

In the case of bending at two angles in one of the reinforcing bar 900 during operation, the small angle is operated as the one-point bending handle 10 as described above, and in the case of adjusting the two points of the large angle, the two-point bending handle on the side ( 11) After adjusting the time corresponding to a certain angle by operating the (timer handle), the reinforcement 900 is hung on the fixed mold 100 of the central axis 101, and the one-point foot switch 12 is operated to make a small angle. By bending and continuously locking the reinforcement 900 in the fixed mold 100 of the desired groove 102 at the desired position and operating the two-point foot switch 13, the standby gear 502 is rotated as described above up to one point. When the bending is reached and the position is reached, the proximity switch 512 is intermittent, and from this time, the timer is operated to rotate until a predetermined time elapses, bending the reinforcement 900 to 2 points, and setting the desired angle. Bending When the timer is controlled to return to the home position, as described above, the chain 600 and the spring 605 connected to the rotary shaft tube 503 return by the bending roller 300 of the standby gear 502. The return is made to the circular motion along the groove 301 bar is a bending operation of the reinforcement 900 in a series of processes.

In particular, the circumferential edge of the air gear 502 in the present draft is formed with a projection 507, the scale falling during the bending work of the reinforcement 900 is gathered into the moving groove 301 inside the bottom of the top plate (3) The inside of the protrusion 507 of the 502 is dropped into the scrap discharge pipe 506 coupled to the bottom of the air fish 502, so that the upper part of the standby fish 502 is always kept clean and the scrap discharge pipe 506 is large. Since it is fixed to the gear 502, the scrap discharge pipe 506 moves according to the rotation of the standby gear 502, so that the scrap is scattered in the lower part of the base 2 instead of only gathering a predetermined place, so that the rebar bending machine 1 is scraped. This prevents excessive closing of the load and extends its service life.In particular, during bending of the rebar 900, accurate control is not performed according to the proximity switch 512 or timer setting. Gear 502 is excessively rotated As the moving shaft 302 of the bending roller 300 travels along the moving groove 301 and hits the end of the moving groove 301, the machine may be damaged. In order to control the rotation, the limit switch 208 is installed at the lower proper position of the upper plate 3 so that when the standby gear 502 is not controlled by the proximity switch 512 or the timer, the control as the limit switch 208 is performed. By doing so, there is an effect such as reducing the failure rate of the rebar bending machine (1).

In addition, the excessive force is applied to the bending roller 300 to prevent the bending roller 300 is naturally separated from the moving shaft 302 by fastening a separate snap ring 305 in the interior of the bending roller 300 The closed end is prevented and the center roller 303 can be replaced and inserted instead of the fixed mold 100. In this case, the bar 901 is mainly used when bending the pipe 901 as well as the rebar 900. When bending of the rollers 901, while maintaining the original state while the pipe 901 maintains its original state by arranging the concave portion 304 conforming to the standard of the pipe 901 at the center outer circumference of the bending roller 300 of the central roller 303 Along the convex portion 304 of the 303, the bending is very easy and accurate.

On the other hand, various control boxes inside the rebar bending machine (1) of this paper can be molded with aluminum casting to reduce the weight, so that the rebar bending machine (1) of this paper can be transported as two people. In addition to savings, manufacturing costs can be reduced.

The support 200 coupled to one side of the upper plate 3 of the present design is the body gear 206 and the tooth 204 of the support 200 is formed in the right and left homogeneous position desired as the coupling bolt 205 in the long hole 203 If you want to change the position of the support 200, if necessary to fix the use of the coupling bolt 205 by appropriately dissociate the support 200 from the body gear 206 to displace the position 180 ° If it is tightened again as the coupling bolt 205, it can be bent by hanging the reinforcement 900 on the ground rod 202. In this case, the auxiliary cover 206 formed separately is the same as the moving shaft 302 of the bending roller 300. After combining the axial rods 107 separately and covering the upper portion of these axial rods 107, 302 can be used in the case of bending in a relatively large round, in this case the reinforcing bar rods 307 on the outer end of the auxiliary cover 306 And a round portion 308 is formed in the axial direction to form a normal rebar 900. When the rods 307 and the support rods 200 are hung on the ground rods 202 and the power is applied as described above, the rebar 900 is bent along the round portion 308 of the auxiliary cover 306 to a desired standard. Since the center shaft tube 500 is a hollow body, the scrap generated during the work falls into the center shaft tube 500 and collects at the lower part of the base, so that the operation of the rebar bending machine 1 due to the scrap or the overload There is an effect such as to prevent the occurrence.

The pedestal 4 of the reinforcing bar bending machine 1 of the present invention functions as the pedestal 4 of the reinforcing bar bending machine 1 as needed, and the reinforcing bar bending machine 1 is supported when the reinforcing bar 900 is bent. Separated from) and placed separately and the pedestal (4) is located on the side of the rebar bending machine (1) to be used for the supply of the reinforcement (900), that is, the rear of the reinforcement (900), which is a relatively long object by its own weight Since the sagging portion is lowered, the pedestal 4 can be hung and used. In this case, since the separate pedestal portions 401 and 402 are formed at both ends of the center of the pedestal 4, the pedestal portions 401 and 402 are provided. ) By laying a conventional unit comb roller (403) to settle the reinforcement (900) and the bending portion in front of the fixed groove 100 of the hanging groove 102 and the bending roller (300) and the support 200 of the ground After hanging on the surface 201, the two footswitches 12 and 13 are selectively operated as described above. By its own rotating force of the combs bear rollers 403 that the road can be bent to be effective, such as made of reinforced magnify the very material supply (900).

In addition, a cap 807 for preventing scrap input is installed in the upper upper plate 3 of the motor 800, and an opening 808 is formed at one side, so that a closed end into which scrap is introduced into the motor 800 during bending of the rebar 900 is formed. In particular, when the motor 800 is replaced after work, it is possible to lift the separated motor 800 through the opening 808 of the cap 807 so that the connection portion between the motor 800 and the reducer 801 When the separate auxiliary panel 804 is assembled as the motor 800 and the assembly bolt 805 and only the bolt 806 coupled to the outer end of the auxiliary panel 804 is disassembled, the motor 800 is opened in the cap 807. Since the collection can be replaced easily through 808, the pinion of the reducer 801, the clutch 809, and the shaft 802 as well as the motor 800 may be replaced at the time of the collection replacement of the motor 800. Closed to 803 is prevented, such as the manpower required to repair and replace the motor 800 compared to the conventional Effects such as to reduce disturbances between and to follow the effects that can greatly improve the work efficiency, especially since there is no need to remove broken when reducer 801 at all.

As described above, the subject of the present invention is composed of a central roller 303 or a fixed mold 100 and a bending roller 300, a driving device, an electric device, a bending angle control device, and the like. Hanging the reinforcement 900 between the rollers 300 and rotating the motor 800, the bending roller 300 is bent while the reinforcement 900 is bent and the bending angle is two bending angles by the angle adjustment device It can be bent at the same time at the same time and the rotation of the bending roller 300 is moved by the gearbox 801 connected to the motor 800 and the clutch gear 502 grounded to the clutch 809 and pinion 803 and the proximity switch In order to control the rotation of the air gear 502 by the 512 and to prevent excessive rotation of the air gear 502 in which the bending roller 300 is built up, a limit switch 208 is installed so that various reinforcement 900 or pipes are installed. 901 can be bent to minimize the incidence of failure It can supply construction aggregates that are used in large quantities in various construction sites or civil engineering sites, minimizing manpower requirements and bending large amounts of aggregates in a short time in a large amount to ensure maximum work efficiency with low labor costs. It is a devised design with great practicality as equipment for various constructions.
