Description

TECHNICAL FIELD

[0001] The utility model relates to reinforcing bar processing technical field more specifically, the utility model relates to a kind of wheeled reinforcing bar straightening machine of extensible reinforcing bar. BACKGROUND

[0002] Reinforcing bar refers to steel bar for reinforced concrete and prestressed reinforced concrete, which has a circular cross section, sometimes a square with rounded corners, including plain round reinforcing bar, ribbed reinforcing bar and twisted reinforcing bar. To ensure uniform stress and improve the quality of buildings constructed with reinforcing bars, reinforcing bars are straightened during production. Straightening methods vary, and reinforcing bars can be straightened manually or mechanically. To reduce work pressure and improve work efficiency, straightening machines are generally used to mechanically straighten reinforcing bars.

[0003] However, most existing straightening machines sometimes need to stretch the straightened reinforcing bars during use. During the stretching process, the reinforcing bars are usually processed by stretching wheels. However, existing straightening machines can only stretch reinforcing bars of the same specification, and cannot stretch reinforcing bars of different specifications according to actual needs. When reinforcing bars need to be stretched to different specifications, they need to be fed into matching straightening machines, which increases the processing cost of reinforcing bars. SUMMARY

[0010] In a preferred embodiment, the bottom of the second sliding block is provided with two grooves, and each of the two grooves is internally provided with a movable wheel, and the movable wheel is in contact with the guide groove.

[0011] The technical effects and advantages of the utility model are as follows:

[0012] Through the setting processing mechanism, the reinforcing steel bars can be extended to corresponding specifications according to actual use requirements in the process of extending the reinforcing steel bars by the device, and through such setting, the reinforcing steel bars need not be sent into corresponding processing equipment for extension when the reinforcing steel bars of multiple different specifications need to be extended, but the extension of the reinforcing steel bars can be directly realized by the device, so that the processing cost of the reinforcing steel bars in processing is reduced, and through the reasonable setting of the processing mechanism, the adjusting plate can be moved to cooperate with the straightening wheel for use, and the stability of the adjusting plate in movement can be obviously improved due to the movable guiding setting of the adjusting plate at the upper and lower parts, and through such reasonable setting, the practicability of the device in use is obviously improved.

DETAILED DESCRIPTION

[0018] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0019] As attached Figures 1-4 The illustrated wheel-type rebar straightening machine for extendable rebar includes a mounting plate 1. Several supports 2 are arranged at the bottom of the mounting plate 1, each support 2 being inverted T-shape. Anti-slip pads can be installed at the bottom of the supports 2 to increase friction between the bottom of the supports 2 and the ground, thereby improving the anti-slip effect of the supports 2. The T-shaped arrangement of the supports 2 also ensures stable fabrication of the mounting plate 1. A guide plate 3 is provided on the front side of the mounting plate 1, with a first through hole inside the guide plate 3. Multiple straightening wheels 4 are arranged on one side of the guide plate 3. By opening the first through hole inside the guide plate 3, the rebar can be fed into the device for processing through the first through hole, guided by the guide plate 3, thus improving the ease of rebar feeding. A groove is provided at the bottom of the mounting plate 1, and a processing mechanism is installed inside the groove.

[0020] As attached Figure 2 , 3As shown in Figure 4, the processing mechanism includes a connecting plate 5. Two fixed plates 6 are provided at the bottom of the connecting plate 5, with the bottom of the connecting plate 5 contacting the top of the fixed plates 6 to allow the connecting plate 5 to move freely without restriction. A reinforcing plate 15 is provided at the bottom of both fixed plates 6. A lead screw 7 is provided between the two fixed plates 6, providing a mounting position for the lead screw 7. A first slider 8 is provided on the lead screw 7, with its top connected to the bottom of the connecting plate 5. The connection between the first slider 8 and the lead screw 7 allows the connecting plate 5 to move via the first slider 8 during operation. An adjusting plate 9 is provided at the top of both fixed plates 6, with the top of the fixed plates 6 contacting the bottom of the adjusting plate 9. The front and rear sides of the connecting plate 5 are connected to the front and rear sides of the inner wall of the adjusting plate 9, respectively. The plate 9 is U-shaped, and two shafts 10 are installed inside the adjusting plate 9. Multiple extension wheels 11 are installed on the shafts 10. By installing extension wheels 11 on the shafts 10, the shafts 10 can drive the extension wheels 11 to operate. The extension wheels 11 extend from front to back, and the gears gradually decrease in size. Two second through holes are opened on the rear side of the adjusting plate 9. An extension plate 12 is installed inside each of the two second through holes. The front side of the extension plate 12 is connected to the rear side of the mounting plate 1. The opening of the second through holes allows the extension plate 12 to enter the interior of the adjusting plate 9 and connect with the mounting plate 1. This allows the extension plate 12 to guide the movement of the adjusting plate 9 and improve the stability of the movement of the adjusting plate 9. The two second through holes on the adjusting plate 9 also have two through holes for installing the shafts 10.

[0021] As attached Figure 2 , 3 As shown in Figure 4, a groove is provided at the top of the extension plate 12, and two guide grooves are provided at the bottom of the inner wall of the groove. A second slider 13 is provided inside the groove. The top of the second slider 13 is connected to the bottom of the adjustment plate 9. Two grooves are provided at the bottom of the second slider 13, and movable wheels 14 are provided inside the two grooves. The movable wheels 14 are in contact with the guide grooves. The groove and grooves at the top of the extension plate 12 allow the second slider 13 and the movable wheels 14 to be placed inside the extension plate 12. With the addition of the second slider 13 and the movable wheels 14, the adjustment plate 9 improves its movement stability and guidance with the help of the extension plate 12, while also improving the smoothness of its movement.

[0022] The working principle of this utility model is as follows: When using this device to straighten and extend steel bars, multiple external drive devices and motors are first connected to drive multiple straightening wheels 4, multiple shafts 10, and lead screws 7 to operate. After the external operation is completed, the position of the extension wheel 11 of the corresponding specification is adjusted according to the extension requirements. The corresponding extension wheel 11 is matched with the straightening wheel 4. During adjustment, only the motor matched with the lead screw 7 needs to be started to drive the lead screw 7 to operate. Through the operation of the lead screw 7, the first slider 8 drives the adjustment plate 9 to move through the connecting plate 5. During the movement of the adjustment plate 9, the position of the extension wheel 11 located in the adjustment plate 9 moves synchronously with the movement of the adjustment plate 9. After the corresponding extension wheel 11 moves to the corresponding position, the motor of the lead screw 7 can be turned off. At this time, the steel bar is fed in through the first through hole opened inside the guide plate 3. It can be straightened by the straightening wheel 4 and then sent into the processing mechanism to be extended by the extension wheel 11.
