[0022] 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.

[0023] like Figures 1 to 3 As shown, a knife edge deformation correction device includes a placement platform 4 capable of horizontal displacement and an adjustment plate 13 disposed above the placement platform 4. A correction clamp 12 is disposed at the bottom of the adjustment plate 13, and the adjustment plate 13 is connected to the placement platform 4 through a positioning component.

[0024] It also includes two support plates 1, which are set on the mirror sides of the placement platform 4, and support frames 2 are fixed on the opposite sides of the two support plates 1. A hydraulic rod I9 and an alignment component are fixed on the top of the support frame 2. A lifting plate 10 is set above the support frame 2 and is slidably connected to the support plate 1 via a slide rail. The hydraulic rod I9 and the alignment component are both connected to the lifting plate 10. The lifting plate 10 is provided with a plug-in component that can be inserted into the adjustment plate 13 to drive the adjustment plate 13 to move up and down.

[0025] In use, the blade is placed on the placement table 4, and then the placement table 4 is moved between the two support plates 1 so that the insertion component can be inserted into the adjusting plate 13. After the insertion component is inserted into the adjusting plate 13, the hydraulic rod I9 works and drives the lifting plate 10 to move down. The lifting plate 10 drives the adjusting plate 13 to move down through the insertion component. During the downward movement of the lifting plate 10, the lifting plate 10 drives the alignment component to work. The alignment component pushes the blade to move so that the blade is vertically aligned with the straightening fixture 12. Then the lifting plate 10 continues to move down and drives the straightening fixture 12 to press the blade. At this time, the positioning component positions the adjusting plate 13 to ensure that the straightening fixture 12 clamps the blade edge. Then the insertion component is disengaged from the adjusting plate 13, the personnel push out the placement table 4, and put the placement table 4 into the tempering equipment for heating and straightening.

[0026] The threaded rod 11, adjusting plate 13, placement platform 4, and other components that need to be placed in the tempering equipment are all made of high-temperature resistant materials and will not deform during blade tempering. The materials include heat-resistant austenitic stainless steel, etc.

[0027] In this embodiment, the alignment assembly includes a cylinder 3, a pressure rod 17, an overflow valve 7, and a one-way valve 8. The cylinder 3, the pressure rod 17, the overflow valve 7, and the one-way valve 8 are all fixed on the support frame 2, and the top of the pressure rod 17 is fixed to the lifting plate 10.

[0028] The pressure rod 17 connects the overflow valve 7, the one-way valve 8 and the cylinder 3. The pressure rod 17 includes a cylinder body, a piston that is slidably connected to the cylinder body, and a rod body that is fixed to the piston. The cylinder body is fixed on the support frame 2, and the rod body is fixed to the lifting plate 10.

[0029] The one-way valve 8 is a spring one-way valve 8. When the piston of the pressure rod 17 moves upward, the cylinder 3 first resets. When the output rod of the cylinder 3 resets, the negative pressure generated when the piston continues to move can drive the one-way valve 8 to open. The spring one-way valve 8 is existing technology.

[0030] Preferably, the one-way valve 8 can also be replaced by an electrically controlled valve, such as a solenoid valve. When the one-way valve 8 is replaced by a solenoid valve, a corresponding distance sensor is installed on the lifting plate 10. When the output end of the hydraulic rod I9 extends and the height of the lifting plate 10 reaches the set height, the solenoid valve opens and stops after the output end of the hydraulic rod I9 stops extending. The linkage control between the solenoid valve, the distance sensor and the hydraulic rod I9 can be achieved by a PLC controller.

[0031] When in use, when the lifting plate 10 moves down, the piston moves down with the lifting plate 10 and generates high-pressure gas which is input into the cylinder 3. The cylinder 3 extends and pushes the blade to align with the straightening fixture 12. When the output end of the cylinder 3 is fully extended, the gas in the cylinder is discharged through the overflow valve 7.

[0032] When the lifting plate 10 moves upward and resets, the piston moves upward, causing the cylinder to generate negative pressure and driving the output end of the cylinder 3 to reset. After the output end of the cylinder 3 resets, the spring check valve 8 opens and allows gas to enter the cylinder 3.

[0033] In this embodiment, a sliding plate 6 is provided at the bottom of the placement platform 4. The sliding plate 6 is slidably connected to a movable plate 5 via a slide rail. The bottom of the movable plate 5 is fixed with a movable wheel. Some ball bearings can also be provided between the sliding plate 6 and the movable plate 5 to increase support.

[0034] In use, the displacement of the placement platform 4 is adjusted by the translation plate 6 and the moving plate 5.

[0035] In this embodiment, a hydraulic rod III21 is fixed inside the support frame 2, and an abutment block that can abut against the placement platform 4 is fixed at the output end of the hydraulic rod III21.

[0036] In use, the hydraulic rod II121 and the abutment block push the placement platform 4 to move, and the placement platform 4 and the threaded rod 11 drive the adjustment plate 13 to move so that the plug-in assembly can be plugged into the adjustment plate 13.

[0037] In this embodiment, the positioning component includes a plurality of threaded rods 11 fixed on the placement platform 4, and the adjusting plate 13 has holes for the threaded rods 11 to pass through. A nut is provided at one end of the threaded rod 11 that passes through the adjusting plate 13.

[0038] In use, the adjusting plate 13 presses the blade edge with the straightening component, and the adjusting plate 13 is positioned by the nut to ensure clamping.

[0039] In this embodiment, the plug-in assembly includes a hydraulic rod II19 fixed inside the lifting plate 10, and a plug-in plate 18 plugged into the lifting plate 10 is fixed to the hydraulic rod II19. The adjusting plate 13 has a plug-in hole for the plug-in plate 18 to be plugged into.

[0040] During use, the hydraulic rod II19 drives the plug plate 18 to be inserted into the plug hole, ensuring that the adjusting plate 13 moves with the lifting plate 10.

[0041] In this embodiment, the adjusting plate 13 is rotatably connected to the threaded fixing rod 15 via the bearing. The threaded fixing rod 15 is detachably fixed to the handwheel 16 via the polygonal column and polygonal hole. Multiple positioning pins 14 are fixed at the bottom of the adjusting plate 13. The straightening fixture 12 has pin holes for the positioning pins 14 to be inserted. The threaded fixing rod 15 is threadedly connected to the straightening fixture 12.

[0042] When it is necessary to replace the straightening clamp 12, rotate the threaded fixing rod 15 by handwheel 16 to remove the straightening clamp 12, then insert the pin hole of the other straightening clamp 12 into the positioning pin 14, and then rotate the threaded fixing rod 15 by handwheel 16.

[0043] Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features; any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
