[0001] This utility model relates to the field of rebar straightening technology, and more specifically, to an automatic traction rebar pre-straightening device. Background Technology
[0002] An automatic traction rebar pre-straightening device is an automated equipment used for pre-processing of rebar. Its core function is to eliminate bending and twisting deformation of rebar during transportation, storage or production through mechanical straightening and automatic traction technology, so as to provide high-quality raw materials for subsequent processing.
[0003] Among the existing publicly available documents, patent publication number CN222970843U discloses an end straightening treatment device for pre-embedded reinforcing bars. This technology involves sliding an adjusting plate left and right along the inside of a limiting sleeve, adjusting it to a suitable position, and then retightening the hand-tightening bolt. The hand-tightening bolt engages with the positioning screw hole, thus defining the position of the adjusting plate and the position of the abutment. The distance between the pusher and the abutment can be adjusted, achieving the function of easily adjusting the operating range and solving the problem that the device lacks the function of easily adjusting the operating range. However, this patent has the following defects.
[0004] The pre-straightening process of steel bars requires the use of a traction device to achieve the traction operation. This requires the hand to be inserted into the bent steel bar, which can easily cause the hand to be squeezed by the traction and compression equipment, resulting in poor safety during the straightening operation.

The positioning cylinder is used to position the inserted reinforcing bar. A protective baffle is fixed on the upper surface of the sleeve plate near its edge line. The protective baffle is used to separate the hand from the straightening roller.
[0006] In a preferred embodiment, a gap is provided between the two straightening rollers, and the output end of the geared motor is fixedly connected to the straightening rollers.
[0007] In a preferred embodiment, the positioning cylinder has an annular cross-sectional shape, and the protective baffle has a concave vertical cross-sectional shape.
[0008] In a preferred embodiment, the positioning cylinder has an opening inside for inserting a reinforcing bar.
[0009] In a preferred embodiment, a fixing strip is installed on one side of the outer wall of the geared motor, and both the geared motor and the support are fixedly connected to the fixing strip.
[0010] In a preferred embodiment, the bottom end of the support bar has two mounting holes, which are symmetrically arranged about the middle of the support sleeve.
[0011] In a preferred embodiment, two positioning sleeves are fixed to one side of the outer wall of the protective baffle, and an insert post is placed inside the positioning sleeve. The positioning sleeve is used to position the insert post. A pressure block is fixed to one end of the insertion post, and a pressure head is fixedly connected to the other end of the insertion post.
[0012] The technical effects and advantages of this utility model are as follows: 1. This utility model uses protective components. The reinforcing bar is inserted into the hole inside the positioning cylinder. At the same time, both hands are guided downward by the protective baffle and placed on the upper surface of the sleeve for limiting protection. The reinforcing bar is inserted into the gap between the two straightening rollers along the positioning cylinder. The straightening rollers pull the reinforcing bar downward. At the same time, the reinforcing bar is pre-straightened from inside the positioning cylinder, which makes the straightening of the reinforcing bar safer. 2. This utility model uses a pressure block to move the insert column upwards, which in turn moves the pressure head downwards. The pressure block then moves the insert column downwards, which in turn moves the pressure head downwards. The pressure head moves downwards along the inner wall of the positioning cylinder, ensuring that all the reinforcing bars are straightened and moved downwards through the gap between the two straightening rollers, making the straightening of the reinforcing bars safer.

[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] like Figure 1 - Figure 4 The present invention relates to an automatic traction rebar pre-straightening device, which is equipped with a protective component. The protective component allows the hands to move downward under the guide of the protective baffle 7 and be limited and protected on the upper surface of the sleeve plate 5. The rebar is inserted into the gap between the two straightening rollers 2 along the positioning cylinder 6, which improves the safety when straightening the rebar. The specific structure of the protective component is as follows.
[0020] In this embodiment, as Figure 1 - Figure 2 As shown, two straightening rollers 2 are rotatably mounted on the inner wall of the support 1. A reduction motor 3 is installed at one end of one of the straightening rollers 2, which drives the straightening roller 2 to rotate. Protective components are installed on the upper surface of the support 1, including: a support bar 4, fixedly installed on the upper surface of the support 1, with a sleeve plate 5 fixedly connected to the top of the support bar 4; a positioning cylinder 6, fixedly located inside the sleeve plate 5, used for positioning the inserted reinforcing bar; and a protective baffle 7 fixed on the upper surface of the sleeve plate 5 near its edge, used to separate the hand from the straightening roller 2. A gap is provided between the two straightening rollers 2, and the output end of the reduction motor 3 is fixedly connected to the straightening roller 2. The positioning cylinder 6 has an annular cross-sectional shape, and the protective baffle 7 has a concave vertical cross-sectional shape.
[0021] In this embodiment, as Figure 2 As shown, the positioning cylinder 6 has a hole 8 inside, which is used to insert a reinforcing bar, so that the reinforcing bar can be inserted into the hole 8 inside the positioning cylinder 6, and the reinforcing bar can be placed for straightening.
[0022] In this embodiment, as Figure 2 As shown, a fixing strip 9 is installed on one side of the outer wall of the geared motor 3. Both the geared motor 3 and the support 1 are fixedly connected to the fixing strip 9 so that the fixing strip 9 can support the geared motor 3 and increase the stability of the geared motor 3.
[0023] In this embodiment, as Figure 3As shown, the bottom end of the support bar 4 has two mounting holes 10. The two mounting holes 10 are symmetrically arranged about the middle of the support 1 so that bolts can be inserted into the mounting holes 10 to ensure the stable use of the support 1.
[0024] When using the automatic traction rebar pre-straightening device of this technology, the support 1 is fixed to the base by inserting bolts into the mounting hole 10. Then, the hands are held on the outer wall of the rebar and inserted into the hole 8 inside the positioning cylinder 6. At the same time, the hands are guided downward by the protective baffle 7, and the sleeve 5 is located on the lower surface of the hands, thus protecting the hands and preventing the hands from being squeezed by the straightening roller 2 when the hands move the rebar downward. At the same time, the rebar is inserted into the gap between the two straightening rollers 2 along the positioning cylinder 6. The support 1 supports the fixing bar 9, and the fixing bar 9 supports the reduction motor 3. The reduction motor 3 drives the straightening roller 2 to rotate, and the straightening roller 2 pulls the rebar downward. At the same time, the rebar is pre-straightened from inside the positioning cylinder 6.
[0025] In this embodiment, as Figure 2 - Figure 4 As shown, two positioning sleeves 11 are fixed on one side of the outer wall of the protective baffle 7. An insert post 12 is placed inside the positioning sleeve 11. The positioning sleeve 11 is used to position the insert post 12. A pressure block 13 is fixed to one end of the insert post 12, and a pressure head 14 is fixedly connected to the other end of the insert post 12.
[0026] When using the automatic traction rebar pre-straightening device of this technology, the hand is held on the outer wall of the pressure block 13. The pressure block 13 drives the insert 12 to move upward. The insert 12 moves upward from the inner wall of the positioning sleeve 11 and moves the pressure head 14 downward. At the same time, the pressure block 13 is pressed down. The pressure block 13 drives the insert 12 to move downward. The insert 12 drives the pressure head 14 to move downward. The pressure head 14 moves downward along the inner wall of the positioning cylinder 6. In this way, the pressure head 14 squeezes the top of the rebar.
[0027] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
