Description

Technical Field

[0001] This invention relates to the field of blade processing technology, specifically to a rotary tiller blade bending device with positioning and anti-deviation function. Background Technology

[0002] Rotary tiller blades are the core working components of agricultural rotary tillage machinery. They are usually made of high-strength and high-toughness materials such as 65Mn spring steel. The cutting edge is quenched to ensure hardness and sharpness. The overall structure is mostly curved blades, chisel-shaped blades, etc. with complex curved surfaces. They are mainly used to break up soil and loosen the surface in tillage operations. The bending precision of the blades directly determines the soil entry angle, soil breaking effect and equipment operation stability during tillage. When the blades of existing rotary tillers are bent, either the blades are clamped too early, causing pre-deformation or interference with feeding, or the blades are clamped too late, which cannot withstand the impact force of the punching. This can easily cause the blades to slip along the tangent of the curved surface, resulting in problems such as deviation in bending angle and incoordination between the cutting edge and the base. Summary of the Invention

[0003] The purpose of this invention is to provide a rotary tiller blade bending device with positioning and anti-deviation function, so as to solve the problems in the prior art where, when bending rotary tiller blades, either the blade is clamped in advance, causing pre-deformation or interference with feeding, or the blade is clamped in a delayed manner, which cannot resist the impact force of the punching, and the blade is prone to slipping along the tangent direction of the curved surface, resulting in bending angle deviation and inconsistent deformation between the cutting edge and the base.

[0004] To achieve the above objectives, the present invention provides the following technical solution: a rotary tiller blade bending device with positioning and anti-deviation function, comprising a stamping device, a power rod, a stamping head, a base, and a fixing block, wherein a positioning component is provided on one side of the stamping device, a lubrication component is provided on one side of the stamping device, and a cooling component is provided on one side of the stamping device. The positioning component includes two sets of bidirectional lead screws rotatably embedded in the fixed block, and both sets of bidirectional lead screws are connected to the limit block through ball nut pairs. The inside of the stamping device is rotatably embedded with a transmission rod, and the outer surface of the transmission rod is fixedly connected with a rotating gear. A gear plate is fixedly connected to one side of the outer surface of the stamping head. The lubrication assembly includes a first liquid cylinder, and a first sliding rod is slidably embedded inside the first liquid cylinder in a vertical direction. A drive plate is fixedly connected to one side of the outer surface of each of the two sets of first sliding rods, and a stamping head is fixedly connected to one side of the outer surface of each drive plate. The first liquid cylinder is connected to a first liquid outlet pipe through a first liquid delivery pipe. The cooling assembly includes a second liquid cylinder, and a second sliding rod is slidably embedded inside the second liquid cylinder in a vertical direction. A pad is fixedly connected to one side of the outer surface of the second sliding rod. A second liquid delivery pipe is fixedly connected to the outer surface of the second liquid cylinder, and a second liquid outlet pipe is fixedly connected to the end of the second liquid delivery pipe away from the second liquid cylinder.

[0005] Preferably, a limiting rod is fixedly connected to one side of the outer surface of both sets of fixed blocks, and the multiple limiting blocks are slidably sleeved on the outer surface of the limiting rod in a horizontal direction.

[0006] Preferably, a second bevel gear is fixedly connected to one side of the outer surface of each of the two sets of bidirectional lead screws, and a first bevel gear is fixedly connected to both sides of the outer surface of the transmission rod. The outer surfaces of the two sets of first bevel gears mesh with the second bevel gears, and the outer surface of the rotating gear meshes with the gear plate.

[0007] Preferably, a first replenishing pipe is fixedly connected to the outer surface of the first liquid cylinder, and a plurality of first liquid outlet heads are provided inside the first liquid outlet pipe.

[0008] Preferably, a first piston is fixedly connected to one side of the outer surface of the first slide rod, and the first piston is slidably embedded inside the first liquid cylinder in a vertical direction.

[0009] Preferably, a second replenishing pipe is fixedly connected to the outer surface of the second liquid cylinder, and a plurality of second liquid outlet heads are provided inside the second liquid outlet pipe.

[0010] Preferably, a second piston is fixedly connected to one side of the outer surface of the second slide rod, and the second piston is slidably embedded inside the second liquid cylinder in a vertical direction. A pad is fixedly connected to the side of the second slide rod away from the second piston, and a spring is wound around the outer surface of the second slide rod.

[0011] Preferably, an air cylinder is fixedly connected to one side of the outer surface of the stamping device, a third slide rod is fixedly connected to one side of the outer surface of the stamping head, and a third piston is fixedly connected to one side of the outer surface of the third slide rod. The third piston is slidably embedded in the air cylinder in a vertical direction, and the third slide rod is slidably embedded in the air cylinder in a vertical direction.

[0012] Preferably, a connecting pipe is fixedly connected to one side of the outer surface of the air cylinder, and an air pipe is fixedly connected to one side of the outer surface of the connecting pipe, with multiple air heads provided inside the air pipe.

[0013] Compared with the prior art, the beneficial effects of the present invention are: This invention synchronizes the fixing and positioning process with the stamping process, and the fixing is activated only when the stamping head is about to come into contact with the blade. This avoids interference with the blade positioning caused by premature clamping and prevents the blade from being easily damaged. At the same time, it avoids stamping deviation caused by delayed clamping, and solves the core problems of excessive and insufficient positioning. Meanwhile, the fixing block automatically releases when not stamping, without hindering the loading and unloading of the blade, simplifying manual operation steps, shortening the single processing cycle time, and indirectly improving production efficiency.

[0014] This invention avoids the problem of edge curling and chipping caused by high hardness and brittleness of cutting tools after quenching and localized stress concentration during bending. Lubricant is sprayed at the initial stage of the stamping process, forming a uniform lubricating film before the cutting edge contacts the die. This prevents lubrication failure due to premature evaporation or delayed spraying, maximizing the reduction of the friction coefficient. The lubricant is sprayed around the cutting edge, ensuring sufficient lubrication in the contact area with the die while preventing excessive direct adhesion of lubricant to the working surface, thus minimizing its impact on edge sharpness and subsequent processing. Simultaneously, the lubricating film isolates the cutting tool from direct hard contact with the stamping head and base, reducing the wear rate of the cutting edge. It also reduces the adhesion of metal debris to the surfaces of the stamping head and base, inhibiting built-up edge formation, extending service life, and reducing edge indentation defects.

[0015] This invention initiates the spraying of a mixed cooling liquid when the blade is fully formed at its maximum stroke during stamping. At this point, the temperature in the blade's bending area is highest due to plastic deformation. A second spray nozzle targets the contact area between the stamping head and the blade, rapidly reducing the local temperature and suppressing the unique thermoelastic rebound of the 65Mn steel rotary tiller blade. The mixture of emulsion and alcohol combines efficient cooling with low corrosiveness, preventing a decrease in the hardness of the hardened layer at the cutting edge due to high temperatures. Simultaneously, the volatility of alcohol reduces residual media and lowers the risk of corrosion. During the downward stamping motion, the air cylinder draws in the blade. The nearby hot air is sprayed out in the opposite direction during the reset, which uses the residual heat to help dry the residual mixture and lubricant on the surface of the blade, avoiding corrosion caused by water stains. Taking the initial, middle, end and reset of the stamping action as the time axis, the initial stamping completes the lubrication ground to reduce frictional resistance for subsequent clamping and bending. The middle stamping starts clamping, which further ensures the stable positioning of the blade on the basis of lubrication. The end of the stamping is cooled to suppress the springback of the 65Mn steel blade. The reset stage completes the blowing to clean the residual medium and debris, thereby improving the processing quality. Attached Figure Description

[0018] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, the technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Therefore, the following detailed description of the embodiments of the present invention provided in the accompanying drawings is not intended to limit the scope of the claimed invention, but merely to illustrate selected embodiments of the invention. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without inventive effort are within the scope of protection of the present invention.

[0019] See Figures 1 to 7 As shown, this invention provides a rotary tiller blade bending device with positioning and anti-deviation function, including a stamping device 1, a power rod 101, a stamping head 102, a base 103, and a fixing block 104. A positioning component, a lubrication component, and a cooling component are provided on one side of the stamping device 1. The positioning component includes two sets of bidirectional lead screws 2 rotatably embedded in the fixing block 104, and both sets of bidirectional lead screws 2 are connected to a limit block 201 via ball nut pairs. A transmission rod 301 is rotatably embedded inside the stamping device 1, and the transmission rod 301 is externally... A rotating gear 3 is fixedly connected to the surface, and a gear plate 304 is fixedly connected to one side of the outer surface of the punch head 102; a limit rod 202 is fixedly connected to one side of the outer surface of each of the two sets of fixed blocks 104, and multiple limit blocks 201 are slidably sleeved on the outer surface of the limit rod 202 in the horizontal direction; a second bevel gear 303 is fixedly connected to one side of the outer surface of each of the two sets of bidirectional lead screws 2, and a first bevel gear 302 is fixedly connected to both sides of the outer surface of the transmission rod 301, and the outer surfaces of the two sets of first bevel gears 302 mesh with the second bevel gears 303; the outer surface of the rotating gear 3 meshes with the gear plate 304. See Figures 1 to 5As shown, the blade is placed on the surface of the base 103, with both ends of the blade inserted into the fixing block 201. The power rod 101 is activated, driving the punch head 102 to punch the blade. When the punch head 102 is about to contact the blade, it drives the gear plate 304 to contact the rotating gear 3. The movement of the gear plate 304 causes the rotating gear 3 to rotate. The rotation of the rotating gear 3, through the transmission rod 301, drives multiple first bevel gears 302 to rotate. These first bevel gears 302 drive the meshing second bevel gears 303 to rotate. The rotation of the second bevel gears 303 then drives the connected bidirectional lead screw 2 to rotate. The rotation of the bidirectional lead screw 2 drives multiple fixing blocks 201 to move in alignment, thereby fixing the blade. The blade is only fixed when it is about to be stamped. Through the above technical solution, the fixing and positioning are synchronized with the stamping process. The fixing is only started when the stamping head 102 is about to come into contact with the blade, avoiding interference with the blade positioning caused by premature clamping and the blade being prone to breakage. At the same time, it avoids stamping deviation caused by delayed clamping, solving the core problems of excessive and insufficient limiting. Meanwhile, the fixing blocks 201 automatically release when not stamping, without hindering the loading and unloading of the blade, simplifying manual operation steps, shortening the single processing cycle time, and indirectly improving production efficiency.

[0020] The lubrication assembly includes a first liquid cylinder 4, and a first slide rod 405 is slidably embedded in the interior of the first liquid cylinder 4 in a vertical direction. A drive plate 407 is fixedly connected to one side of the outer surface of each of the two sets of first slide rods 405, and a stamping head 102 is fixedly connected to one side of the outer surface of the drive plate 407. The first liquid cylinder 4 is connected to a first outlet pipe 402 through a first liquid delivery pipe 401. A first replenishment pipe 404 is fixedly connected to the outer surface of the first liquid cylinder 4. A plurality of first outlet heads 403 are provided inside the first outlet pipe 402. A first piston 406 is fixedly connected to one side of the outer surface of the first slide rod 405, and the first piston 406 is slidably embedded in the interior of the first liquid cylinder 4 in a vertical direction. See Figures 1 to 6As shown, the operator adds an oily extreme pressure lubricant containing molybdenum sulfide into the first liquid cylinder 4 beforehand through the first replenishment pipe 404. When the stamping head 102 is opened for stamping, the stamping head 102 drives the first slide rod 405 and the first piston 406 to slide inside the first liquid cylinder 4 via the drive plate 407. The first piston 406 squeezes out the lubricant inside the first liquid cylinder 4 through the first delivery pipe 401, and then delivers it to the first outlet pipe 402 through the first delivery pipe 401. The lubricant is sprayed out through multiple first outlet nozzles 403, and the multiple first outlet nozzles 403 are directed towards the cutting edge of the blade. Through the above technical solution, the high hardness and brittleness of the tool after quenching are avoided, preventing local bending during punching. Stress concentration can lead to edge curling and chipping of the cutting edge. Lubrication spraying at the initial stage of the stamping process forms a uniform lubricating film before the cutting edge contacts the die, preventing lubrication failure caused by premature evaporation or delayed spraying. This minimizes the coefficient of friction. The lubricant is sprayed around the cutting edge, ensuring sufficient lubrication in the contact area between the cutting edge and the die, while preventing excessive lubricant from adhering directly to the working surface of the cutting edge, thus reducing the impact on the sharpness of the cutting edge and subsequent processing. At the same time, the lubricating film can isolate the blade from direct hard contact with the stamping head 102 and the base 103, reducing the wear rate of the cutting edge. It also reduces the adhesion of metal debris to the surfaces of the stamping head 102 and the base 103, inhibits the formation of built-up edge, extends service life, and reduces cutting edge indentation defects.

[0021] The cooling assembly includes a second liquid cylinder 5, and a second slide rod 505 is vertically slidably embedded inside the second liquid cylinder 5. A pad 507 is fixedly connected to one side of the outer surface of the second slide rod 505. A second liquid delivery pipe 501 is fixedly connected to the outer surface of the second liquid cylinder 5, and a second liquid outlet pipe 502 is fixedly connected to the end of the second liquid delivery pipe 501 away from the second liquid cylinder 5. A second liquid replenishment pipe 504 is fixedly connected to the outer surface of the second liquid cylinder 5, and multiple second liquid outlet heads 503 are provided inside the second liquid outlet pipe 502. A second piston 506 is fixedly connected to one side of the outer surface of the second slide rod 505, and the second piston 506 is vertically slidably embedded inside the second liquid cylinder 5. A pad 507 is fixedly connected to the side away from the second piston 506, and a spring 508 is wound around the outer surface of the second slide rod 505; an air cylinder 6 is fixedly connected to one side of the outer surface of the stamping device 1, a third slide rod 601 is fixedly connected to one side of the outer surface of the stamping head 102, and a third piston 602 is fixedly connected to one side of the outer surface of the third slide rod 601. The third piston 602 is vertically slidably embedded inside the air cylinder 6, and the third slide rod 601 is vertically slidably embedded inside the air cylinder 6; a connecting pipe 603 is fixedly connected to one side of the outer surface of the air cylinder 6, and an air pipe 604 is fixedly connected to one side of the outer surface of the connecting pipe 603. Multiple air heads 605 are provided inside the air pipe 604. See Figures 1 to 7As shown, the operator adds the emulsion and alcohol mixture into the second liquid cylinder 5 beforehand through the second replenishment pipe 504. After the punch head 102 deforms the blade, the drive plate 407 contacts the pad 507, pushing the pad 507 and the second slide rod 505 to move. The second slide rod 505 drives the second piston 506 to move inside the second liquid cylinder 5, thereby squeezing out the mixture inside the second liquid cylinder 5 through the second delivery pipe 501. The mixture then passes through the second outlet pipe 502 and the second outlet head 5. 03. The gas is extruded and sprayed onto the contact position between the blade and the punch head 102. When the punch head 102 starts to move, it drives the third slide rod 601 and the third piston 602 to move. At this time, the air cylinder 6 draws external gas through the connecting pipe 603 and multiple air heads 605. When the punching is completed and the punch head 102 returns to its original position, the gas inside the air cylinder 6 is extruded by the third piston 602, and the extracted gas is extruded again through the air heads 605. The extruded gas is then blown onto the blade surface again through the air heads 605. The described technical solution involves spraying a mixed cooling liquid when the blade is fully formed at its maximum stroke. At this point, the temperature in the blade bending area is highest due to plastic deformation. The second liquid outlet 503 sprays onto the contact area between the stamping head 102 and the blade, rapidly reducing the local temperature and suppressing the unique thermoelastic rebound of the 65Mn steel rotary tiller blade. The mixture of emulsion and alcohol combines efficient cooling with low corrosiveness, preventing a decrease in the hardness of the quenched layer at the cutting edge due to high temperatures. Simultaneously, the volatility of alcohol reduces residual media and lowers the risk of corrosion. During the downward stamping process, the air cylinder... 6. Hot air is drawn in from near the blade and sprayed out in the opposite direction during resetting. This utilizes residual heat to help dry the residual mixture and lubricant on the blade surface, preventing rust caused by water residue. The stamping process is structured around the initial, middle, and final stages, with resetting as the timeline. Lubrication is laid at the beginning of stamping to reduce frictional resistance during subsequent clamping and bending. Clamping is initiated during the middle stage of stamping to further ensure stable blade positioning based on lubrication. Cooling is implemented at the end of stamping to suppress the springback of the 65Mn steel blade. The resetting stage involves blowing to remove residual media and debris, thereby improving machining quality.

[0022] Working principle: The blade is placed on the surface of the base 103, and both ends of the blade are inserted into the fixed block 201. By activating the power rod 101, the punch head 102 is driven to punch the blade. When the punch head 102 is about to contact the blade, it drives the gear plate 304 to contact the rotating gear 3. The movement of the gear plate 304 drives the rotating gear 3 to rotate. The rotation of the rotating gear 3 drives multiple first bevel gears 302 to rotate through the transmission rod 301. The multiple first bevel gears 302 drive the meshing second bevel gears 303 to rotate. The rotation of the second bevel gears 303 drives the connected double-acting screw 2 to rotate. The rotation of the double-acting screw 2 drives multiple fixed blocks 201 to move in alignment, thereby fixing the blade. The blade is only fixed when it is about to be punched.

[0023] Workers pre-fill the first liquid cylinder 4 with an oily extreme pressure lubricant containing molybdenum sulfide through the first replenishment pipe 404. When the punch head 102 is turned on for punching, the punch head 102 drives the first slide rod 405 and the first piston 406 to slide inside the first liquid cylinder 4 via the drive plate 407. The first piston 406 squeezes out the lubricant inside the first liquid cylinder 4 through the first delivery pipe 401, and then delivers it to the first outlet pipe 402 through the first delivery pipe 401. The lubricant is sprayed out through multiple first outlet heads 403, and the multiple first outlet heads 403 are directed toward the cutting edge of the blade.

[0024] The staff adds the emulsion and alcohol mixture to the second liquid cylinder 5 in advance through the second replenishment pipe 504. After the punch head 102 deforms the blade, the drive plate 407 contacts the pad 507, pushing the pad 507 and the second slide rod 505 to move. The second slide rod 505 drives the second piston 506 to move inside the second liquid cylinder 5, thereby squeezing out the mixture inside the second liquid cylinder 5 through the second delivery pipe 501. The mixture then passes through the second outlet pipe 502 and the second outlet head 5. 03 The gas is squeezed and sprayed to the contact position between the blade and the punch head 102. When the punch head 102 starts to move, it drives the third slide rod 601 and the third piston 602 to move. At this time, the air cylinder 6 draws external gas through the connecting pipe 603 and multiple air heads 605. When the punching is completed and the punch head 102 is reset, the gas inside the air cylinder 6 is squeezed by the third piston 602, and the extracted gas is squeezed out again through the air head 605. At this time, the squeezed out gas is blown onto the blade surface again through the air head 605.
