Description

Technical Field

[0001] This invention relates to the field of shear blade processing technology, specifically to a high-speed grinding metallurgical shear blade edge smoothing and cutting device. Background Technology

[0002] Shear blades are the core cutting components of shearing equipment (such as disc shears, flying shears, cross shears, and slitting machines in metallurgical steel rolling mills). They are usually used in pairs, and through the relative movement of the two cutting edges, they achieve the separation and shearing of metal blanks such as plates, strips, and bars. High-speed ground metallurgical shear blades refer to shear blades manufactured using high-performance materials (such as high-speed steel, powder metallurgy high-speed steel, or cemented carbide) and machined through high-speed precision grinding processes. To eliminate microscopic defects on the cutting edge and improve its surface quality, a leveling cutting device is usually used to cut the shear blade. A leveling and cutting device is a specialized piece of equipment or mechanism used for finishing shear blades. It is mainly used to remove minor deformations, burrs, cracks, or uneven areas that occur on the shear blade edge after heat treatment or rough grinding, so that the blade edge achieves high straightness, high smoothness, and flatness. By using a leveling and cutting device, the shear blade edge can be subjected to more uniform force after leveling, making it less prone to stress concentration and premature chipping, which can significantly improve its service life. At the same time, the shearing surface is flatter, the burrs are smaller, and the dimensional accuracy is higher, which is beneficial to improving the shearing quality.

[0003] In existing technologies, when metal cutting is performed using a flat cutting device, the shear blade is usually placed on a platform, clamped, and then moved and fed. Because it is not possible to simultaneously achieve positioning constraints on the shear blade during the feeding process, the operation process is cumbersome and the clamping and positioning time is long, which is not conducive to improving the overall efficiency of shear blade cutting. Therefore, in order to solve the above problems, a high-speed grinding metallurgical shear blade flat cutting device is proposed. Summary of the Invention

[0004] The purpose of this invention is to provide a high-speed grinding metallurgical shear blade edge smoothing cutting device to solve the problem mentioned in the background art, which is that the shear blade cannot be positioned and constrained synchronously during the feeding process, resulting in a cumbersome operation process and long clamping and positioning time, thus hindering the improvement of the overall efficiency of shear blade cutting.

[0005] To achieve the above objectives, the present invention provides the following technical solution: a high-speed grinding and metallurgical shear blade edge smoothing cutting device, comprising a machine base, a frame fixedly connected to the surface of the machine base, and a cutting tool provided at the bottom end of the frame; The surface of the machine tool is provided with a feeding mechanism, which includes a first screw, a moving plate, and a placement platform.

The movable block is movably disposed on the inner side of the placement platform, and the pressure block is fixedly connected to the top of the movable block.

[0006] Preferably, the feeding mechanism further includes a fixed plate, which is fixedly connected to the upper surface of the machine tool, and the first screw is movably connected to the fixed plate. A motor is fixedly installed on the surface of the machine tool, and the first screw is fixedly connected to the output end of the motor. A limit rod is fixedly connected to the inner surface of the fixed plate, and the moving plate is movably connected to the limit rod.

[0007] Preferably, the limiting mechanism further includes a rotating rod, which is movably connected to the inner side of the fixed plate, and a transmission belt is movably connected to the surface of the rotating rod. Both ends of the transmission belt are movably connected to the first screw and the rotating rod through pulleys.

[0008] Preferably, a rotating rod is movably connected to the inner side of the movable plate, and a first helical gear is fixedly connected to the surface of the rotating rod. A first connecting block is fixedly connected to the surface of the rotating rod, and the first connecting block is in two sets and fixed to the rotating rod. Both the rotating rod and the first connecting block are movably located inside the movable plate.

[0009] Preferably, the inner side of the rotating rod is provided with a groove, and the groove is provided in two sets. The end of the first connecting block away from the rotating rod is movable inside the groove, and both the rotating rod and the first helical gear are movable on the rotating rod and the first connecting block.

[0010] Preferably, a fixing block is fixedly connected to the lower surface of the placement platform, and a positive and negative screw is movably connected to the inner side of the fixing block. A second helical gear is fixedly connected to the surface of the positive and negative screw, and a moving block is threadedly connected to the surface of the positive and negative screw.

[0011] Preferably, the movable blocks are in two sets and are movably connected to the positive and negative screws, and a first connecting rod is fixedly connected to the surface of the movable blocks. A first movable groove is opened on the inner side of the movable plate, and the first connecting rod moves inside the first movable groove.

[0012] Preferably, a second connecting rod is fixedly connected to the surface of the first connecting rod, and a third connecting rod is fixedly connected to the surface of the second connecting rod. The limiting block is fixedly connected to the top of the third connecting rod. The first connecting rod is connected to the moving block in two groups, and the second connecting rod, the third connecting rod, and the limiting block are all arranged in two groups. A second movable groove is opened on the inner side of the placement platform, and the third connecting rod moves inside the second movable groove.

[0013] Preferably, the auxiliary mechanism further includes a second connecting block, which is fixedly connected to the top of the movable block, and a sliding groove is provided on the inner side of the movable block. The second connecting blocks are in two sets corresponding to the movable block, and the sliding grooves are in two sets within the movable block.

[0014] Preferably, the end of the second connecting block away from the moving block is movable inside the slide groove, and a third movable groove is provided on the inner side of the placement platform, and the movable block is movable inside the third movable groove.

[0015] Compared with the prior art, the beneficial effects of the present invention are: 1. The operation of the motor drives the first screw to rotate, which in turn moves the moving plate and the placement table. As a result, the position of the shear blade on the placement table changes, which can feed the shear blade and facilitate the movement of the shear blade to the cutting position, so as to realize the metal cutting of the cutting tool.

[0016] 2. By setting up the rotating rod and the rotating arm, in conjunction with the action of the first helical gear, the rotating rod can drive the first helical gear to move along with it during the movement of the moving plate. At the same time, the first helical gear can rotate under the action of the rotating rod and drive the second helical gear. In turn, the forward and reverse screws rotate, which can make the moving block drive the limiting block to move. The movement of the limiting block can achieve the effect of limiting the shear blade, thereby ensuring the stability of the shear blade during cutting and improving the cutting quality.

[0017] 3. By setting up the movable block and the second connecting block in conjunction with the opening of the second connecting block, the movement of the movable block can drive the movable block to move vertically, and the pressure block will rise and fall accordingly. This can achieve the downward pressure of the pressure block on the end of the shear blade away from the cutting edge, thereby preventing the radial runout of the shear blade. This makes the shear blade more stable during the cutting process and can better ensure the cutting quality.

[0018] 4. The shear blade is fed by moving the placement table. The movement of the moving block is achieved by the cooperation of the first and second helical gears, which in turn enables the synchronous movement of the limit block and the pressure block. This achieves the effect of limiting and constraining the shear blade during the feeding process, making the operation process more convenient and saving clamping and positioning time. This improves the overall efficiency of shear blade cutting and facilitates better metal cutting. Attached Figure Description

[0021] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0022] Please see Figure 1-8 One embodiment provided by the present invention: The motor 22 used in this application is a product that can be purchased directly from the market. Its principle and connection method are existing technologies well known to those skilled in the art, so they will not be described in detail here.

[0023] A high-speed grinding and metallurgical shear blade edge smoothing cutting device includes a machine base 1. A frame 11 is fixedly connected to the surface of the machine base 1, and a cutting tool 12 is provided at the bottom end of the frame 11. A feeding mechanism is provided on the surface of the machine base 1. The feeding mechanism includes a first screw 21, a moving plate 23, and a placement table 24. The first screw 21 is movably disposed on the top of the machine base 1, and the moving plate 23 is movably connected to the first screw 21 by a thread. The placement table 24 is fixedly connected to the top of the moving plate 23. A limit mechanism and an auxiliary mechanism are provided on the feeding mechanism. The limit mechanism includes a limit block 314, which is movably disposed on the top of the placement table 24. The auxiliary mechanism includes a movable block 4 and a pressure block 41. The movable block 4 is movably disposed inside the placement table 24, and the pressure block 41 is fixedly connected to the top of the movable block 4. By placing the shear blade on the placement table 24 and cooperating with the setting of the cutting tool 12, the shear blade can be cut, thereby improving the flatness of the shear blade edge.

[0024] Furthermore, the feeding mechanism also includes a fixed plate 2, which is fixedly connected to the upper surface of the machine base 1. The first screw 21 is movably connected to the fixed plate 2. A motor 22 is fixedly installed on the surface of the machine base 1, and the first screw 21 is fixedly connected to the output end of the motor 22. A limit rod 25 is fixedly connected to the inner surface of the fixed plate 2, and a moving plate 23 is movably connected to the limit rod 25. The operation of the motor 22 drives the first screw 21 to rotate. With the setting of the limit rod 25, the moving plate 23 can drive the placement platform 24 to move, thereby realizing the feeding of the shear blade and facilitating the movement of the shear blade to the underside of the cutting tool 12 for cutting.

[0025] Furthermore, the limiting mechanism also includes a rotating rod 3, which is movably connected to the inner side of the fixed plate 2. A transmission belt 31 is movably connected to the surface of the rotating rod 3. Both ends of the transmission belt 31 are movably connected to the first screw 21 and the rotating rod 3 through pulleys. Through the setting of the transmission belt 31, the rotation of the first screw 21 can drive the transmission belt 31, thereby enabling the transmission of the rotating rod 3. The rotation of the rotating rod 3 can drive the first helical gear 33 to rotate and drive the second helical gear 38, thereby enabling the transmission of the positive and negative screws 37. This achieves the effect that the moving block 39 moves under the action of the positive and negative screws 37 and drives the limiting block 314 to move accordingly. This allows the shear blade to be clamped and fixed simultaneously during the feeding process, thereby ensuring the stability of the shear blade during the cutting process.

[0026] Furthermore, a rotating rod 32 is movably connected to the inner side of the movable plate 23, and a first helical gear 33 is fixedly connected to the surface of the rotating rod 32. A first connecting block 34 is fixedly connected to the surface of the rotating rod 3, and the first connecting block 34 is fixed to the rotating rod 3 in two sets. Both the rotating rod 3 and the first connecting block 34 are movably located inside the movable plate 23. Through the setting of the first connecting block 34 and the opening of the groove 35, when the movable plate 23 moves, the rotating rod 32 can drive the first helical gear 33 to move accordingly under the action of the movable plate 23, thereby changing the position of the first helical gear 33. When the rotating rod 3 rotates, the rotating rod 32 can drive the first helical gear 33 to rotate under the action of the first connecting block 34 and the groove 35, thereby ensuring the transmission of the first helical gear 33 to the second helical gear 38.

[0027] Furthermore, a groove 35 is provided on the inner side of the rotating rod 32, and the groove 35 is provided in two sets. The end of the first connecting block 34 away from the rotating rod 3 is movable on the inner side of the groove 35. The rotating rod 32 and the first helical gear 33 are both movable on the rotating rod 3 and the first connecting block 34. Through the arrangement of the rotating rod 32 and the first helical gear 33, the rotating rod 32 drives the first helical gear 33 to rotate under the action of the rotating rod 3, which can realize the transmission of the first helical gear 33 to the second helical gear 38. In this way, the positive and negative screws 37 can rotate and drive the moving block 39 to move.

[0028] Furthermore, a fixing block 36 is fixedly connected to the lower surface of the placement platform 24, and a positive and negative screw 37 is movably connected to the inner side of the fixing block 36. A second helical gear 38 is fixedly connected to the surface of the positive and negative screw 37, and a moving block 39 is threadedly connected to the surface of the positive and negative screw 37. By rotating the positive and negative screw 37, the moving block 39 can be moved, and the first connecting rod 310 can move accordingly under the action of the moving block 39. This enables the second connecting rod 312 to drive the third connecting rod 313 and the limiting block 314 to move, thereby achieving the effect of limiting the cutting blade by the limiting block 314, which helps to ensure the stability of the cutting blade and thus improves the cutting quality.

[0029] Furthermore, the movable block 39 is movably connected to the positive and negative screws 37 in two sets, and the surface of the movable block 39 is fixedly connected to the first connecting rod 310. The inner side of the movable plate 23 is provided with a first movable groove 311, and the first connecting rod 310 moves inside the first movable groove 311. By opening the first movable groove 311, the first connecting rod 310 can be limited, so the movable block 39 is not easy to deviate under the action of the positive and negative screws 37, which can ensure that the movable block 39 drives the first connecting rod 310 to move stably, thereby ensuring the movement of the limiting block 314.

[0030] Furthermore, a second connecting rod 312 is fixedly connected to the surface of the first connecting rod 310, and a third connecting rod 313 is fixedly connected to the surface of the second connecting rod 312. A limiting block 314 is fixedly connected to the top of the third connecting rod 313. The first connecting rod 310 is connected to the moving block 39 in two sets, and the second connecting rod 312, the third connecting rod 313, and the limiting block 314 are all arranged in two sets. A second movable groove 315 is opened on the inner side of the placement platform 24, and the third connecting rod 313 moves inside the second movable groove 315. Through the arrangement of the second connecting rod 312 and the third connecting rod 313, the limiting block 314 can move under the action of the first connecting rod 310, thereby facilitating the limiting of both sides of the shear blade through the movement of the limiting block 314, making it less likely for the shear blade to shift during cutting, thus enabling better cutting.

[0031] Furthermore, the auxiliary mechanism also includes a second connecting block 42, which is fixedly connected to the top of the movable block 39. A sliding groove 43 is provided on the inner side of the movable block 4. The second connecting blocks 42 are arranged in two sets corresponding to the movable block 39, and the sliding grooves 43 are arranged in two sets within the movable block 4. With the arrangement of the second connecting blocks 42 and the opening of the sliding grooves 43, the second connecting blocks 42 move along with the movable block 39 during its movement. They can move within the sliding grooves 43, thereby enabling the movable block 4 to drive the pressure block 41 to move vertically. The vertical movement of the pressure block 41 and the pressing of the shear blade can prevent the shear blade from radially jumping during the cutting process, thus facilitating better cutting of the shear blade.

[0032] Furthermore, the end of the second connecting block 42 away from the moving block 39 is movable inside the slide groove 43. The inner side of the placement platform 24 is provided with a third movable groove 44, and the movable block 4 is movable inside the third movable groove 44. The opening of the third movable groove 44 facilitates the vertical movement of the movable block 4 under the action of the moving block 39, thereby driving the pressure block 41 to move vertically as well, so that the pressure block 41 can descend and press down on the end of the shear blade away from the blade edge.

[0033] Working principle: When in use, the motor 22 is electrically connected to an external power source. The operator starts the motor 22 by pressing the switch. The motor 22 drives the first screw 21 to rotate. The moving plate 23 is limited by the limiting rod 25 and moves on the machine base 1 under the action of the first screw 21 and moves on the surface of the limiting rod 25. As a result, the placement table 24 moves accordingly, realizing the feeding of the shear blade on the placement table 24, so that the shear blade can move to the cutting position. When the first screw 21 rotates, the transmission belt 31 moves under the action of the first screw 21 and drives the rotating rod 3. The first connecting block 34 rotates under the action of the rotating rod 3. The rotating rod 32 rotates under the action of the first connecting block 34 and the groove 35 and moves inside the moving plate 23. Then the first helical gear 33 rotates and drives the second helical gear 38. The positive and negative screws 37 rotate under the action of the second helical gear 38, so that the moving block 39 moves under the action of the positive and negative screws 37 and drives the first connecting rod 310 to move. At the same time, the first connecting rod 310 moves inside the first movable groove 311. The second connecting rod 312 moves under the action of the first movable groove 311 and causes the third connecting rod 313 to drive the limiting block 314 to move. At the same time, the third connecting rod 313 moves inside the second movable groove 315. Thus, during the feeding of the shear blade, the limiting block 314 moves synchronously to limit the shear blade. When the moving block 39 moves, the second connecting block 42 moves accordingly and slides inside the slide groove 43. Then, under the action of the moving block 39, the movable block 4 moves vertically inside the third movable groove 44 and drives the pressure block 41 to rise and fall. This allows the pressure block 41 to press down on the end of the shear blade away from the cutting edge. Thus, while feeding, the limiting block 314 limits the shear blade, and the pressure block 41 can also press the shear blade at the same time, thereby preventing the shear blade from radially jumping.

[0034] The above are merely preferred embodiments of the present invention and are not intended to limit the present invention in any way. Those skilled in the art can readily implement the present invention based on the accompanying drawings and the description above. However, any modifications, alterations, or variations made by those skilled in the art without departing from the scope of the present invention, using the disclosed technical content, are equivalent embodiments of the present invention. Furthermore, any modifications, alterations, or variations made to the above embodiments based on the essential technology of the present invention are still within the protection scope of the present invention.
