[0028] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0029] See also Figures 1 to 6 , the utility model provides a technical solution:

[0030] A material guide device for a steel bar straightening machine comprises a fixed plate 1 and mounting plates 2 fixedly connected to both sides of the fixed plate 1, threaded mounting holes are provided on the mounting plates 2, a material guide cylinder 3 is fixedly connected to the front end surface of the fixed plate 1, and a feed groove is provided in the material guide cylinder 3 and the mounting plate 2;

[0031] The front end opening of the guide cylinder 3 is provided with an adjusting mechanism 4 at equal distances in a ring shape;

[0032] The adjusting mechanism 4 includes a roller 47 that wraps around the outside of the steel bar to limit the position, and a buffer connected to the guide tube 3 is arranged outside the roller 47;

[0033] The outside of the material guiding cylinder 3 is provided with a driving member for adjusting the length of the buffer member.

[0034] The roller 47 has a groove on its outside, and the roller 47 fits against the surface of the steel bar through the groove.

[0035] Specifically, Figure 5 As shown, the buffer member includes a rectangular sleeve 45, and an ear plate 48 is symmetrically fixed to the lower end of the rectangular sleeve 45, the roller 47 is located between the two ear plates 48 and is rotatably connected to the ear plate 48, the upper side of the rectangular sleeve 45 is movably connected to a buffer rod 44, the lower end of the buffer rod 44 extends into the rectangular sleeve 45 through the upper end opening of the rectangular sleeve 45, a buffer spring 46 is arranged between the inside of the rectangular sleeve 45 and the bottom of the buffer rod 44, and the rectangular sleeve 45, the buffer rod 44 and the buffer spring 46 together constitute a buffer member.

[0036] By adopting the above technical solution, the roller 47 is wrapped and fitted on the surface of the steel bar to be straightened passing through the guide tube 3 through the groove, so as to limit the steel bar feeding process, and during the steel bar feeding process, as the bending curvature of the steel bar changes, the roller 47 will be squeezed, and the rectangular sleeve 45 will be further squeezed to cooperate with the telescopic rod, and the buffer spring 46 will be used to buffer the impact force, thereby reducing the tail swinging range during the steel bar feeding process and reducing the safety hazards of the steel bar straightening process.

[0037] Specifically, Figure 4 As shown, the driving member includes an outer driving ring 41 rotatably connected to the outside of the material guide cylinder 3, the top of the buffer rod 44 passes through the material guide cylinder 3 and extends to the outside of the material guide cylinder 3, and is located between the material guide cylinder 3 and the outer driving ring 41, and the top of the buffer rod 44 is integrally connected with a spherical end 43, and an arc-shaped extrusion block 42 is fixed at a position corresponding to the spherical end 43 inside the outer driving ring 41, and the arc-shaped extrusion block 42 is designed in a triangular structure.

[0038] By adopting the above technical solution, due to the need for processing steel bars of different diameters, it is necessary to keep the roller 47 able to completely fit the surface of the steel bar through the groove, so it is necessary to adjust the position of the roller 47 in the material guide barrel 3. Therefore, the user can rotate the outer drive ring 41, and use the arc-shaped extrusion block 42 with a triangular structure in the outer drive ring 41 to tilt the arc surface to squeeze the spherical end 43, and then drive the spherical end 43 to move, and further drive the buffer rod 44 and the rectangular sleeve 45 to move, and then allow the roller 47 to fit and wrap around the surface of the steel bar through the groove.

[0039] Specifically, Figure 6 As shown, the outer surface of the material guide cylinder 3 is sleeved with a nut ring 5 at the rear side of the outer driving ring 41 , and the material guide cylinder 3 is threadedly connected and fixed to the outer driving ring 41 through the nut ring 5 .

[0040] By adopting the above technical solution, after the rotation adjustment of the outer driving ring 41 is completed, the position of the outer driving ring 41 needs to be fixed. Therefore, the user fixes the outer driving ring 41 by screwing the nut ring 5 and threading the nut ring 5 with the outer driving ring 41 and the guide barrel 3.

[0041] Specifically, Figure 5 As shown, a high temperature resistant rubber pad is sleeved and fixed in the groove on the outer surface of the roller 47 .

[0042] By adopting the above technical solution, the feeding displacement of the steel bar is constantly in contact with the roller 47, and long-term work will easily cause wear of the roller 47 and the generation of noise. Therefore, by sleeved a high-temperature resistant rubber pad in the outer groove of the roller 47, noise reduction is achieved and the contact between the steel bar and the roller 47 is avoided. Subsequent users only need to replace the high-temperature resistant rubber pad.

[0043] Working principle: Due to the need to process steel bars of different diameters, it is necessary to keep the roller 47 able to completely fit the surface of the steel bar through the groove, so it is necessary to adjust the position of the roller 47 in the guide barrel 3. Therefore, the user can rotate the outer drive ring 41, and use the arc-shaped extrusion block 42 with a triangular structure in the outer drive ring 41 to squeeze the spherical end 43 with the inclined arc surface, and then drive the spherical end 43 to move, and further drive the buffer rod 44 and the rectangular sleeve 45 to move, and then make the roller 47 fit and wrap around the surface of the steel bar through the groove. The roller 47 is wrapped and fit on the surface of the steel bar to be straightened after passing through the guide barrel 3 through the groove. The surface limits the steel bar feeding process, and during the steel bar feeding process, as the bending curvature of the steel bar changes, the roller 47 will be squeezed, and the rectangular sleeve 45 will be further squeezed to cooperate with the telescopic rod, and the buffer spring 46 will be used to buffer the impact force, thereby reducing the tail swing range during the steel bar feeding process and reducing the safety hazards of steel bar straightening processing. The feeding displacement of the steel bar is constantly in contact with the roller 47, and long-term work can easily cause wear of the roller 47 and the generation of noise. Therefore, a high-temperature resistant rubber pad is sleeved in the outer groove of the roller 47 to achieve noise reduction and avoid contact between the steel bar and the roller 47. Subsequent users only need to replace the high-temperature resistant rubber pad.

[0044] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of the utility model, rather than to limit it. Although the utility model has been described in detail with reference to the aforementioned embodiments, ordinary technicians in this field should understand that they can still modify the technical solutions recorded in the aforementioned embodiments, or replace some or all of the technical features therein with equivalents. However, these modifications or replacements do not make the essence of the corresponding technical solution deviate from the scope of the technical solution of the embodiments of the utility model.
