Description

Technical Field

[0001] This utility model relates to the field of shear blade processing technology, and in particular to a metallurgical shear blade polishing mechanism. Background Technology

[0002] Metallurgical shear blades are key consumable parts used in the metallurgical industry for shearing metal materials. They are usually installed on shearing machines and are widely used in hot rolling and cold rolling production lines and shearing processing centers in steel plants. During the production and processing of shear blades, the blade edges need to be polished to make them sharper.

[0003] For example, patent number CN220217726U discloses a metallurgical shear blade polishing device. This device, through the setting of an adjustment mechanism, can fix the shear blade body on a movable plate via an anti-slip plate and a first screw. By rotating the worm gear, the worm wheel and the second screw are rotated. The second screw drives the movable block to move, thereby adjusting the tilt angle of the movable plate. The height of the polishing machine is adjusted by an electric push rod, thereby polishing the shear blade body. This avoids the problem of low production efficiency and unstable processing quality caused by workers manually tilting the shear blade body at a certain angle and then contacting it with the polishing wheel when polishing the blade surface.

[0004] For example, patent number CN222078766U discloses a grinding machine for processing irregularly shaped metallurgical shear blades. A servo motor drives a first mounting shaft to rotate, which in turn drives a mounting plate, a first electric telescopic rod, a connecting plate, and a grinding machine to rotate to the required grinding angle. Then, the first electric telescopic rod drives the connecting plate and the grinding machine to move, so that the grinding disc on the grinding machine comes into contact with the cutting tool. The grinding machine then performs grinding, while simultaneously moving back and forth, thereby achieving multi-angle automatic grinding of cutting blades of any length. This greatly improves the applicability of grinding irregularly shaped metallurgical shear blades and also increases the grinding efficiency.

[0005] While existing metallurgical shear blade polishing mechanisms incorporate tilt adjustment structures to allow the polishing wheel to adapt and fit the shear blade's geometric angle, in actual operation, angle adjustment requires multiple trial grindings to verify the blade's fit. This process is not only cumbersome and inefficient, but also prone to angle errors due to human judgment deviations or improper adjustments. These errors affect the uniformity of the contact surface between the polishing wheel and the blade, leading to decreased polishing accuracy and impacting the shear blade's lifespan and cutting performance.

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.

[0025] Please see Figures 1-5 This utility model provides an embodiment of a metallurgical shear blade polishing mechanism, comprising a base 1, a clamping mechanism 2 and a drive frame 3 at the upper end of the base 1, a movable frame 4 on the left side of the drive frame 3, a slide rod 5 fixedly installed at the left end of the movable frame 4, a friction plate 6 on the side of the slide rod 5, a lifting seat 7 on the left side of the slide rod 5, a bidirectional lead screw 8 inside the lifting seat 7, a groove 9 on the surface of the lifting seat 7, a friction block 10 inside the groove 9, an adjusting seat 11 on the left side of the movable frame 4, a polishing machine body 12 fixedly installed on the right side of the adjusting seat 11, insertion frames 13 on the front and rear sides of the adjusting seat 11, a connecting rod 14 hinged to the upper right end of the insertion frame 13, a connecting rod 2 15 hinged to the lower right end of the insertion frame 13, a distance sensor 16 fixedly installed on the surface of the adjusting seat 11, a partition 17 on the left side of the adjusting seat 11, and an insertion frame 18 on the right side of the partition 17.

[0026] Please see Figures 1-5In this embodiment, the clamping mechanism 2 includes a drive seat 201. The surfaces of the drive seat 201 and the base 1 are slidably connected by a slide rail. An electric push rod 1 for driving the drive seat 201 to move left and right is fixedly installed on the left side of the upper end of the base 1. A clamping seat 202 is provided above the drive seat 201. An electric push rod 202 for driving the clamping seat 202 to rise and fall is fixedly installed between the drive seat 201 and the clamping seat 202. The drive frame 3 includes a drive screw 301 and a guide rod 302 arranged parallel to the drive screw 301. The side of the drive frame 3... A motor for driving the drive screw 301 to rotate is fixedly installed. The moving frame 4 is threadedly connected to the drive screw 301 and slidably connected to the guide rod 302. A sliding sleeve 701 is fixedly installed on the front side of the lifting seat 7. The sliding sleeve 701 is slidably connected to the outer side of the sliding rod 5. A bidirectional screw 8 is arranged through the lifting seat 7 from front to back and is rotatably connected to the lifting seat 7. Knobs 801 are fixedly installed at both ends of the bidirectional screw 8 extending to the outer side of the lifting seat 7. Two sliding grooves 9 are symmetrically arranged from front to back about the lifting seat 7. The bidirectional screw 8 extends into the sliding grooves 9. The inner side is threadedly connected to the friction block 10. The right end of the friction block 10 is slidably connected to the inner side of the slide groove 9. The left end of the friction block 10 extends to the outer side of the slide groove 9 and is fixedly installed with a friction plate. The friction plate and the friction plate 6 are tightly fitted together. The friction plate 6 and the moving frame 4 are fixedly connected. The shear blade to be polished is fixed on the clamping seat 202 of the clamping mechanism 2. The drive seat 201 is driven to move left and right by the electric push rod one, and the clamping seat 202 is driven to move up and down by the electric push rod two. The position of the shear blade edge is adjusted. The bidirectional lead screw 8 is rotated by rotating the knob 801. The two friction blocks 10 slide along the slide groove 9, causing them to disengage from the friction plate 6, thus releasing the locking of the lifting seat 7. This allows the lifting seat 7 to slide freely up and down along the slide rod 5. By adjusting the height of the lifting seat 7, the connecting rod 14 and the connecting rod 2 15 work together to drive the adjusting seat 11 to move until the partition 17 is completely in contact with the cutting edge of the shear blade, thereby calibrating the tilt angle of the polishing wheel 121. After calibration, the knob 801 is rotated in the opposite direction to drive the two friction blocks 10 to re-engage tightly with the friction plate 6, thereby locking the lifting seat 7 to fix the tilt angle of the polishing wheel.

[0027] Please see Figures 2-5In this embodiment, a polishing wheel 121 is provided on the left side of the adjustment seat 11, extending from the output end of the polishing machine body 12. A plug-in frame 13 is symmetrically arranged about the front and rear of the adjustment seat 11 and is fixedly connected to it. The right end of connecting rod 14 is fixedly connected to the moving frame 4, and the right end of connecting rod 15 is hinged to the moving frame 4. A partition plate 17 is arranged parallel to the adjustment seat 11. A gasket is fixedly installed on the left side of the partition plate 17, and the front and rear ends of the right side of the partition plate 17 are fixedly connected to the plug-in frame 18. 8 and the plug-in frame 13 are slidably connected. A handle is fixedly installed on the upper end of the plug-in frame 18. By pulling the handle, the plug-in frame 18 is separated from the plug-in frame 13, the partition 17 is removed, and the obstruction of the polishing wheel 121 is removed. The electric push rod, combined with the distance sensor 16, provides real-time distance feedback and pushes the clamping mechanism 2 to drive the shear blade to smoothly contact the polishing wheel 121. At the same time, it drives the drive screw 301 in the frame 3 to work, driving the moving frame 4 to move back and forth, thereby achieving continuous and uniform polishing of the shear blade edge.

[0028] During operation, the shear blade to be polished is fixed on the clamping seat 202 of the clamping mechanism 2. Electric push rod one drives the drive seat 201 to move left and right, while electric push rod two drives the clamping seat 202 to move up and down, adjusting the position of the shear blade edge. Rotating knob 801 rotates the bidirectional lead screw 8, driving the two friction blocks 10 to slide along the slide groove 9, disengaging them from the friction plate 6 and releasing the locking of the lifting seat 7, allowing it to slide freely up and down along the slide rod 5. Adjusting the height of the lifting seat 7 causes connecting rod one 14 and connecting rod two 15 to work together, moving the adjusting seat 11 until the partition plate 17 is completely in contact with the shear blade edge. The adjustment mechanism calibrates the tilt angle of the polishing wheel 121. After calibration, the knob 801 is rotated in the opposite direction to drive the two friction blocks 10 to re-fit tightly with the friction plate 6, thereby locking the lifting seat 7 to fix the tilt angle of the polishing wheel. Then, the handle is pulled to disengage the plug frame 18 from the plug frame 13, and the partition 17 is removed to remove the obstruction of the polishing wheel 121. The electric push rod, combined with the distance sensor 16, provides real-time distance feedback and pushes the clamping mechanism 2 to drive the shear blade to smoothly contact the polishing wheel 121. At the same time, it drives the drive screw 301 in the frame 3 to work, driving the moving frame 4 to move back and forth, thereby achieving continuous and uniform polishing of the shear blade edge.

[0029] Compared to the prior art (patent number CN220217726U) which uses angle adjustment of the shear blade clamping mechanism, and the prior art (patent number CN222078766U) which uses angle adjustment of the polishing machine, both require multiple trial grindings to verify the blade edge fit during actual operation. This process is not only cumbersome and inefficient, but also prone to angle errors due to human judgment deviations or inadequate adjustments. The polishing mechanism in this application adjusts the position of the lifting seat 7, driving the first connecting rod 14 and the second connecting rod 15 to move the adjusting seat 11, so that the partition 17 fits against the shear blade surface. This achieves rapid alignment of the polishing wheel 121 tilt angle with the geometric angle of the shear blade edge, improving the accuracy of angle adjustment and reducing adjustment errors. After calibration, by rotating the knob 801 in the opposite direction, the friction block 10 is forced to press tightly against the friction plate 6, quickly locking the position of the lifting seat 7. This makes the adjustment process convenient and quick, and eliminates the need for repeated trial grindings and human experience judgment, thus improving polishing efficiency and accuracy.

[0030] Furthermore, any content not described in detail in this specification is existing technology known to those skilled in the art.

[0031] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
