[0001] The utility model relates to the technical field of metallurgical industry, in particular to a pressure correction indentation improvement device. Background Art

[0002] Generally, hot-processed steel is prone to deformation such as bending, wavy, and buckling when it cools down. Therefore, a straightening device is needed to straighten it. The steel is placed and fixed on the straightening platform, and the hydraulic device is used to supply sufficient pressure to the straightening head. The driving device drives the straightening head to reciprocate on the steel, continuously squeezing the steel to change its straightness, thereby straightening the deformed steel.

[0003] The following defects or deficiencies exist in the straightening process:

[0004] 1. The existing 1,500-ton pressure straightening machine in the finishing operation area of ​​the special steel division is designed for round steel of 150mm-300mm. When straightening round steel of ≥260mm, indentations will appear on the surface of the steel after straightening due to the design of the hammer head, which requires manual grinding, causing secondary damage to the steel and increasing the labor intensity of employees;

[0005] 2. It is difficult to ensure the straightness of steel during the steel straightening process. Utility Model Content

DETAILED DESCRIPTION

[0025] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.

[0026] Example 1, reference Figure 1-4 , a pressure straightening and indentation improvement device, comprising a workbench 1, a moving seat 2 and a straightening head 3;

[0027] A mounting groove 4 is provided on the top of the workbench 1, a bidirectional screw rod 5 is installed in the mounting groove 4, the moving seat 2 is symmetrically threadedly sleeved outside the bidirectional screw rod 5, and a bearing seat 6 is fixedly connected to the top of the moving seat 2;

[0028] One end of the bidirectional screw rod 5 passes through the mounting slot 4 and is coaxially connected to the output shaft of the servo motor 11. The bidirectional screw rod 5 is symmetrically provided with two sections of threads with different rotation directions along the center line.

[0029] A "U"-shaped groove is provided on the top of the bearing seat 6, and a buffer pad is arranged in the "U"-shaped groove.

[0030] Example 2, reference Figure 1-4 This embodiment is optimized on the basis of embodiment 1, specifically:

[0031] A servo electric cylinder 7 is arranged on one side of the top of the workbench 1, a bracket 8 is slidably arranged on the top of the servo electric cylinder 7, a straightening cylinder 9 is arranged at the bottom of the bracket 8, a mounting plate 10 is fixedly connected to the bottom of the piston rod of the straightening cylinder 9 by bolts, and a straightening head 3 is fixedly connected to the bottom of the mounting plate 10 by bolts;

[0032] The straightening head 3 is a metal hammer head, and the outside of the straightening head 3 is fixedly connected with a nylon sling 12 by screws;

[0033] A slider 13 is slidably connected to the top of the servo electric cylinder 7, and the bracket 8 is fixedly connected to the top of the slider 13;

[0034] A position sensor 14 is provided at one side of the bottom of the mounting plate 10, and the position sensor 14 is an infrared sensor;

[0035] A controller 15 is disposed on one side of the top of the workbench 1 , and the controller 15 is connected to the signal receiving ends of various components through signal lines.

[0036] Working principle: The utility model is a pressure straightening and indentation improvement device. When the user uses the device, the workpiece to be straightened is placed on the supporting seat 6, and the workpiece is pushed to move in another direction. Then the straightening cylinder 9 is started, so that the piston rod of the straightening cylinder 9 drives the mounting plate 10 to move up and down. When the straightening head 3 fixedly connected by bolts at the bottom of the mounting plate 10 is against the surface of the workpiece, if the piston rod continues to move downward, a downward force will be applied to the workpiece, and this force will correct the straightness of the workpiece. The cut nylon sling 12 is installed on the hammer head, folded into two layers, and tightened with screws. When the round steel is straightened, the nylon sling 12 contacts the surface of the steel to straighten the steel. If the nylon sling 12 is damaged or dropped during the straightening process, the machine is stopped immediately for replacement. The straightening force applied to the workpiece is adjusted by controlling the movement distance of the piston rod of the straightening cylinder 9, so as to straighten the workpiece. During the straightening process, the servo electric cylinder 7 can be started according to the straightening requirements to drive the bracket 8 to move, thereby controlling the straightening position and improving the straightening accuracy.

Any technician familiar with the technical field can make equivalent replacements or changes within the technical scope disclosed by the present invention according to the technical scheme and the utility model concept of the present invention, which should be covered by the protection scope of the present invention.
