Previously, a small seven-roller straightening machine was generally used to straighten the coil (coil) specimens. The roller straightening method caused large deformation of the test specimens and serious work hardening, which had a great impact on the tensile performance experiment. The seven-roller straightening machine can only meet small specifications and cannot cover all specifications of wire rods. The seven-roller straightening machine has a high failure rate, mainly due to steel jamming, gear defects, bearing damage and other failures, which seriously affect the normal production rhythm.

[0030] See also Figure 1 to Figure 2 As shown, the present invention provides a rapid straightening machine, comprising:

[0031] A mounting platform 1, on which a plurality of mounting holes are provided;

[0032] Two mounting plates 2, the two mounting plates 2 are arranged on the mounting platform 1 through bolts and corresponding mounting holes, the two mounting plates 2 are parallel to each other, and a straightening area is formed between the two mounting plates 2;

[0033] A plurality of limit assemblies 3 and a plurality of straightening assemblies 4 are further provided in the straightening area. The limit assemblies 3 and the straightening assemblies 4 are mounted on the mounting plate 2 .

[0034] A lifting mechanism is arranged on the installation platform 1, and a movable end of the lifting mechanism passes through, and the movable end of the lifting mechanism faces the middle of the straightening area.

[0035] It should also be noted that the mounting platform provides a stable foundation for the entire straightening machine. The multiple mounting holes provided on it allow the two mounting plates to be flexibly and stably mounted on the platform by bolts. A straightening area is formed between the two parallel mounting plates, which provides space for the straightening of materials such as steel bars. The limit assembly and the straightening assembly provided in the straightening area act together on the steel bars and other materials to be straightened. The limit assembly is used to limit the range of movement of the material to ensure that it remains stable during the straightening process; while the straightening assembly directly straightens the material to achieve the required straightness;

[0036] The movable end of the lifting mechanism faces the middle of the straightening area, and can locally flatten the steel bars and other materials during operation, thereby achieving the straightening effect. It is set on the installation platform, and acts on the straightening area through the movable end through the platform or a specific opening. Compared with the original seven-roller straightening machine, the fast straightening machine of the present invention adopts a local flattening method, which causes less deformation to the test sample and slight work hardening phenomenon, thus having no effect on its tensile performance experimental operation.

[0037] Exemplarily, a lifting opening is provided on the mounting platform 1, and the lifting mechanism includes a cylinder 201 and a pressure head 202. The cylinder 201 is arranged below the mounting platform 1, and the pressure head 202 is installed at the end of the piston rod of the cylinder 201. The cylinder 201 is used to drive the pressure head 202 to approach or move away from the straightening area.

[0038] Exemplarily, all the limiting components 3 and all the straightening components 4 are located at the same horizontal height.

[0039] It should also be noted that the purpose of setting them at the same height is to ensure that the steel bars can maintain a straight state during the straightening process and improve the straightening effect.

[0040] Exemplarily, the pressing head 202 is cylindrical, a screw hole is provided on the pressing head 202 , and the pressing head 202 is threadedly connected to the piston rod of the cylinder 201 .

[0041] It should also be noted that the purpose of providing the screw holes on the pressure head 202 is to be able to replace the pressure head 202 to match different steel bar specifications and improve adaptability.

[0042] Exemplarily, the mounting plate 2 is a U-shaped plate, and both ends of the mounting plate 2 are respectively fixed on the mounting platform 1 .

[0043] It should also be noted that the purpose of setting a U-shaped plate is to provide space for the activities of the jacking mechanism, while at the same time the straightening effect can be intuitively observed and timely adjustments can be made.

[0044] Exemplarily, the limiting assembly 3 is a limiting bolt, and the limiting bolt is transversely arranged on the upper part of the two mounting plates 2.

[0045] Exemplarily, the straightening assembly 4 is a straightening bolt, which is arranged on the upper part of the two mounting plates 2 and is respectively located on the outside of all the limiting bolts.

[0046] Exemplarily, the limiting bolts and the straightening bolts are rotatably arranged on the upper parts of the two mounting plates 2 .

[0047] It should also be noted that the purpose of the rotation setting is that when the bent steel bar is pushed in, the limit bolt and the straightening bolt can rotate along with it to avoid damage caused by rigid contact.

[0048] Exemplarily, a straightening machine cylinder sleeve 203 is further provided on the installation platform 1 , and the straightening machine cylinder sleeve 203 is sleeved on the outer side of the piston rod of the cylinder 201 .

[0049] It should also be noted that the straightening machine cylinder sleeve 203 provides a solid support for the piston rod and bears the lateral thrust generated by the piston rod during movement. This ensures the stable movement of the piston rod in the cylinder and avoids failures caused by shaking or deviation. At the same time, the straightening machine cylinder sleeve 203 also acts as a track for the piston, guiding it to reciprocate, ensuring the accuracy and reliability of the movement.

[0050] To sum up, a fast straightening machine is adopted according to the present invention. Compared with the original seven-roller straightening machine, the straightening mechanism of the present invention adopts local flattening, which effectively causes small deformation of the test sample, slight work hardening phenomenon, and has no effect on its tensile performance experimental operation; it can cover all specifications and varieties of wire; its failure rate is low, which can effectively ensure positive impact.

[0051] The above embodiments are merely illustrative of the principles and effects of the present invention, and are not intended to limit the present invention. Anyone familiar with the technology may modify or change the above embodiments without violating the spirit and scope of the present invention. Therefore, all equivalent modifications or changes made by a person with ordinary knowledge in the technical field without departing from the spirit and technical ideas disclosed by the present invention should still be covered by the claims of the present invention.
