Abstract

The present invention discloses an efficient cutting device for processing vehicle steel rims, which relates to the technical field of vehicle steel rim processing, and comprises a cutting table and a discharge and conveying mechanism for unloading and conveying steel strips, wherein a cutting assembly is arranged on the top of the cutting table. When the present invention is used, the cylinder pushes the upper anti-sway plate to move downward, and by cooperating with the moving gear and the adjusting gear, drives the lower anti-sway plate to move upward, so that the rubber ball contacts the upper and lower surfaces of the steel strip, and at the same time drives the first nozzle to move, maintaining a shorter distance from the steel strip. Through the cooperation of the anti-sway plate and the rubber ball, rigid vertical constraints are formed on the upper and lower surfaces of the cutting portion of the steel strip. At the same time, the first nozzle and the second nozzle spray multiple airflows vertically to the upper and lower surfaces of the steel strip, forming a multi-point airflow flexible constraint. Combined with the rigid vertical constraint, the elastic deformation of the cutting portion is controlled within a very small range, so that the cutting portion can be better maintained in place.

Description

Technical Field

[0001] The present invention relates to the technical field of vehicle steel rim processing, and in particular to a high-efficiency cutting device for vehicle steel rim processing. Background Art

[0002] Vehicle rims, commonly known as wheel hubs, are annular components mounted on vehicle axles, supporting the tires and connecting the wheels to the axles. Typically made of metal, they are a crucial component of the vehicle's travel system. They primarily secure the tires, ensuring a tight fit between the tires and the wheel hub, maintaining vehicle stability during driving, and supporting the vehicle's own weight, as well as the weight of its cargo and passengers, while also withstanding impact forces during driving. The raw materials for rim processing are typically steel plates or strips, which must first be processed into specific sized blanks using intelligent manufacturing equipment, such as cutting equipment, for subsequent forming.

[0003] In the prior art, when cutting the raw steel strip for vehicle rims, a feeding device is generally installed on one side of the cutting device and a discharge conveyor on the other side. The steel strip coil is fed by the feeding device. When the length of the steel strip conveyed by the discharge conveyor reaches the specified length, the feeding device and the discharge conveyor simultaneously pause, and the cut portion of the steel strip is suspended below the cutting blade. During cutting, the instantaneous impact force of the blade causes the steel strip to bend elastically. The stress release at the moment of fracture causes the cut end of the cut steel strip to rebound and shake, which in turn causes the entire steel strip to shake and become unstable, causing the steel strip to deviate and affect subsequent discharge and conveying. The shaking steel strip also increases friction between the steel strip and the discharge conveyor belt, causing increased wear of the conveyor belt and shortening its service life.

[0004] Therefore, we propose an efficient cutting device for vehicle steel rim processing in order to solve the problems raised in the above background technology. Summary of the Invention

[0005] The purpose of the present invention is to provide an efficient cutting device for processing vehicle steel rims, so as to solve the problem proposed in the above-mentioned background technology that when the raw steel strip of the vehicle steel rim is cut, due to the suspended state of the cutting part of the steel strip, the cutting part of the steel strip will produce a large rebound at the moment of breaking, causing the cut steel strip to shake unsteadily, causing the steel strip to deviate, and also increasing the friction between the steel strip and the unloading conveyor belt, resulting in increased wear of the conveyor belt and affecting the service life.

[0017] Compared with the prior art, the present invention has the following beneficial effects:

[0018] 1. When the present invention is used, the cylinder pushes the upper anti-sway plate downward, and through the cooperation of the moving gear and the adjusting gear, drives the lower anti-sway plate upward, so that the rubber ball contacts the upper and lower surfaces of the steel strip, and at the same time drives the first nozzle to move, maintaining a shorter distance from the steel strip. Through the cooperation of the anti-sway plate and the rubber ball, rigid vertical constraints are formed on the upper and lower surfaces of the cutting part of the steel strip. At the same time, the first nozzle and the second nozzle spray multiple airflows vertically to the upper and lower surfaces of the steel strip, forming multi-point flexible airflow constraints. Combined with the rigid vertical constraints, the elastic deformation of the cutting part is controlled within a very small range, so that the cutting part can be better maintained in place, thereby avoiding the shaking of the entire cutting section of the steel strip due to local rebound, which is beneficial to improving its stability in conveying and unloading on the discharge conveying mechanism.

[0019] 2. When the present invention is used, the dual-axis forward and reverse motor is started to drive the rotating rod, the second gear, the chain and the first gear to rotate, and then the inclination plate and the second nozzle are driven to rotate into an inclined state, thereby adjusting the angle of the second nozzle so that it is inclined toward the cutting position of the steel strip, changing the ejection direction of the airflow, and changing the original five vertical airflows into two inclined airflows combined with three inclined airflows. The vertical airflow continues to exert pressure on the steel strip in the vertical direction, maintaining control over the vertical displacement of the steel strip. The three inclined airflows blow toward the cutting position of the steel strip from a specific angle, so that the steel strip returns to a stable state. They can also blow toward the moving cutting knife to accelerate the cooling of the blade and blow away debris.

[0020] 3. When the present invention is in use, the hydraulic mechanism pushes the cutting blade downward to perform cutting. The horn amplifies the transducer's small amplitude to the larger amplitude required by the cutting blade. This vibration is then transmitted to the cutting blade's edge, generating a high-frequency micro-cutting effect, effectively reducing the cutting force of the steel strip and improving the surface quality of the cut. The horn's vibration direction is coupled to the cutting direction of the cutting blade, creating a combined failure mode of "high-frequency micro-shearing + hydraulic main cutting" at the cutting blade, achieving efficient cutting.

[0035] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings.

The two anti-sway plates 402 move relative to each other at the same time, and with the cooperation of the rubber ball 404, a rigid vertical constraint is formed on the cutting end of the steel strip. The two air injection pipes 415 drive the first nozzle 419 to approach the steel strip under the movement of the anti-sway plate 402, and spray high-speed air flow to the upper and lower sides of the steel strip through the first nozzle 419 to form a uniform pneumatic pressure layer. A PLC control system 6 is provided on the front surface of the top of the cutting table 1, and a mounting groove 7 is provided on the front surface of the cutting table 1. An ultrasonic generator 8 is provided on the bottom surface of the mounting groove 7. Both ends of the two air injection pipes 415 are fixedly connected to an elastic hose 416, and one end of the four elastic hoses 416 is fixedly connected to a fixed pipe 417. The four fixed pipes 417 are each longitudinally The two fixed tubes 417 distributed in the direction form a group, and three second connecting tubes 420 are fixedly connected between the two groups of fixed tubes 417. The outer surfaces of the six second connecting tubes 420 are fixedly connected to multiple telescopic hoses 421, and one end of the multiple telescopic hoses 421 is fixedly connected to the second nozzle 422. A center rod 409 is fixedly installed at the center of the front surface and the rear surface of the anti-sway frame 401. The outer surfaces of the two center rods 409 are movably sleeved with adjusting gears 408. The outer surfaces of the two adjusting gears 408 are meshed and connected with two moving rows of teeth 407. The interiors of the four moving rows of teeth 407 are provided with sliding holes 411. The interiors of the four sliding holes 411 are movably embedded with limiting rods 410. The outer surfaces of both sides of the anti-sway frame 401 are provided with moving holes 41 2. Two stabilizing frames 414 are fixedly installed on both sides of the top of the anti-sway frame 401. Three second connecting pipes 420 distributed laterally form a group of six second connecting pipes 420. Two reinforcing plates 423 are fixedly installed on the outer surfaces of the two groups of second connecting pipes 420 away from the second nozzle 422. Multiple mounting holes 413 are opened on the opposite sides of the two anti-sway plates 402. A fixing frame 406 is fixedly installed on the output end of the cylinder 405. The bottom of the fixing frame 406 is fixedly installed on the top of one of the anti-sway plates 402. The outer surfaces of one side of the four movable teeth 407 are respectively fixedly installed on the two side edges of the opposite side of the two anti-sway plates 402. One end of the four limit rods 410 is respectively fixedly installed on the top and bottom of the outer surfaces of both sides of the anti-sway frame 401.The two anti-sway plates 402 are movably embedded in the four movable holes 412 on both sides of their outer surfaces. The four stabilizing frames 414 are fixedly mounted on both sides of the cutting table 1. The four reinforcement plates 423 are fixedly mounted on the top and bottom of the anti-sway frame 401 on their outer surfaces. One end of the multiple first nozzles 419 is fixedly mounted in the multiple mounting holes 413. The outer surfaces of one end of the two air injection pipes 415 are fixedly mounted on opposite sides of the two anti-sway plates 402. The output end of the air cylinder 405 is movably extended through the interior of the anti-sway frame 401.

[0037] In this embodiment, during operation, a coil of steel strip is delivered to the loading conveyor mechanism 10 via a feeding device. The strip then passes through the space between two anti-sway plates 402 and arrives at the discharge conveyor mechanism 2. When the length of the steel strip on the discharge conveyor mechanism 2 meets the required length, both the discharge conveyor mechanism 2 and the loading conveyor mechanism 10 automatically pause. The cylinder 405 then activates, pushing the upper anti-sway plate 402 downward via the fixed frame 406, driving the two movable rows of teeth 407 on either side downward. At this point, the two meshing adjustment gears 408 simultaneously rotate, driving the other two movable rows of teeth 407 upward, thereby driving the lower anti-sway plate 402 upward. This causes the upper and lower rows of rubber balls 404 to move relative to each other and contact the upper and lower surfaces of the steel strip. The relative movement of the two anti-sway plates 402 also moves the upper and lower air injection pipes 415, the first connecting pipe 418, and the first nozzle 419, pulling on the corresponding elastic hoses 416 to stretch and expand without affecting the movement of the air injection pipes 415. When cylinder 405 automatically pauses, the upper and lower surfaces of the steel strip contact the rubber ball 404, respectively, and the first nozzle 419 maintains a short distance from the steel strip. One end of each of the two air injection pipes 415 is connected to the air injection equipment via a swivel plate. The anti-sway plate 402 and rubber ball 404 work together to create rigid vertical constraints on the upper and lower surfaces of the cut strip, limiting vertical displacement and preventing the cut end from rebounding during cutting. At the same time, the air injection equipment is activated, and the high-pressure airflow is sequentially delivered to the two air injection pipes 415, the elastic hose 416, and the fixed pipe 417. The high-pressure airflow then enters the first connecting pipe 418 and the second connecting pipe 420, and is blown vertically toward the upper and lower surfaces of the steel strip through the first nozzles 419 distributed vertically. At this time, two vertical high-pressure airflows are formed inside the anti-sway frame 401, forming a uniform pneumatic pressure layer, which is like applying a flexible pressure constraint to the steel strip, further limiting the vertical displacement of the steel strip. The airflow pressure acts vertically on the steel strip, offsetting the elastic contraction stress within the material during cutting and reducing rebound sway after cutting. In addition, the high-pressure airflow in the second connecting pipe 420 enters multiple flexible hoses 421, and is vertically ejected toward the upper and lower surfaces of the steel strip through the second nozzles 422 distributed vertically, forming three vertical airflow pressure constraints closer to the cutting point of the steel strip, which is conducive to improving the constraint effect at the cutting end of the steel strip. The anti-sway assembly 4 creates multiple flexible airflow constraints at the cut section of the steel strip. Combined with rigid vertical constraints, this minimizes elastic deformation at the cut section, effectively maintaining the cut section in place. This prevents local rebound from causing the entire cut section of the steel strip to sway, improving the stability of the strip during transport on the discharge conveyor mechanism 2. Multiple flexible rubber balls 404 are provided, distributing surface pressure on the steel strip to multiple contact points, avoiding surface indentations caused by excessive force applied to a single rigid ball.Then the cutting component 3 is started to cut the constrained steel strip. After cutting, the cutting component 3 is reset, the anti-sway component 4 is reset, and then the discharge conveying mechanism 2 and the feeding conveying mechanism 10 resume work. The cut steel strip is discharged and conveyed through the discharge conveying mechanism 2, which solves the problem that when the raw steel strip of the vehicle steel rim is cut, the steel strip cutting part is in a suspended state, and the steel strip cutting part will produce a large rebound at the moment of breaking, causing the cut steel strip to shake unsteadily, causing the steel strip to deviate, and also increasing the friction between the unloading conveyor belt, resulting in increased wear of the conveyor belt and affecting the service life.

[0038] Example 2: Figure 7-Figure 8 and Figure 10-11 As shown, two inclination assemblies 5 are provided, and the two inclination assemblies 5 each include three inclination plates 501, and the front and rear surfaces of the six inclination plates 501 are fixedly installed with limit shafts 502, and one end of the plurality of limit shafts 502 is fixedly installed with a first gear 503, and each three adjacent first gears 503 of the plurality of first gears 503 form a group, and the outer surfaces of the four groups of first gears 503 are meshed with chains 504, and the interiors of the four chains 504 are meshed with second gears 505, and the top and bottom of the anti-sway frame 401 are fixedly installed with mounting brackets 506, and the interiors of the two mounting brackets 506 are fixedly installed with dual-axis forward and reverse motors 507, and the two output ends of the two dual-axis forward and reverse motors 507 are fixedly installed with rotating rods 508, and one end of the four rotating rods 508 is fixedly connected to the outer surface of one side of the four second gears 505 respectively. Then, three adjacent limit shafts 502 form a group, and the outer surfaces of the four groups of limit shafts 502 are movably sleeved with support frames 510. The outer surfaces of the four support frames 510 are respectively fixedly installed on both sides of the top and bottom of the anti-sway frame 401. The outer surfaces of the four rotating rods 508 are movably sleeved with two support plates 509. The eight support plates 509 are each longitudinally distributed with four support plates 509 forming a group. The outer surfaces of the two groups of support plates 509 are respectively fixedly installed on the bottom of the top of the anti-sway frame 401. The multiple second nozzles 422 are each longitudinally distributed with multiple second nozzles 422 forming a group. The outer surfaces of the six groups of second nozzles 422 are respectively fixedly installed on the inside of the six tilt plates 501. A storage slot 9 is opened on one side of the inner bottom surface of the cutting table 1, and the outer surface of one tilt component 5 is located inside the storage slot 9.

[0039] In this embodiment, when in use, the two dual-axis forward and reverse motors 507 are started to drive the corresponding rotating rod 508 and the second gear 505 to rotate together, and drive the chain 504 and the multiple first gears 503 to rotate. Under the support of the support frame 510, the limit shaft 502 is driven to rotate, so that the tilt plate 501 connected thereto rotates. At this time, the tilt plate 501 gradually rotates from a horizontal state to an inclined state, so that the upper and lower six groups of second nozzles 422 all rotate together, from a vertical state to an inclined state. Driven by the dual-axis forward and reverse motor 507, the angle of the second nozzle 422 is adjusted to tilt it toward the cutting position of the steel strip, thereby changing the ejection direction of the airflow. Then the gas injection equipment is started, and the high-pressure airflow is ejected simultaneously through the first nozzle 419 and the second nozzle 422. At this time, the direction of the airflow changes, such as Figure 12 As shown, from Figure 12 The left-hand side of the diagram in the middle becomes the right-hand side, where the original five vertical airflows are replaced by two inclined airflows combined with three inclined airflows. The vertical airflows continue to exert vertical pressure on the steel strip, maintaining control over its vertical displacement. The three inclined airflows blow toward the cutting area of ​​the steel strip from specific angles, generating lateral forces. These lateral forces can balance the lateral swaying tendency of the steel strip caused by uneven force during the cutting process. If the steel strip sways slightly, the lateral force of the inclined airflow can quickly react, applying a reverse force to the cutting area of ​​the steel strip, correcting the swaying direction and restoring the steel strip to a stable state. The inclined airflow can also blow toward the moving cutting blade 304, accelerating blade cooling and blowing away debris.

[0040] Example 3: Figure 1-Figure 5 As shown, the cutting assembly 3 includes a cutting frame 301, a hydraulic mechanism 302 is provided on the top of the cutting frame 301, an isolation damping plate 303 is installed on the bottom of the hydraulic mechanism 302 by bolts, a cutting knife 304 is installed on the bottom of the isolation damping plate 303 by screws, a variable amplitude rod 306 is installed on the outer surface of one side of the cutting knife 304 by bolts, a transducer 307 is installed on one end of the variable amplitude rod 306 by bolts, a slide rail 305 is fixedly installed on the outer surface of one side of the cutting frame 301, a damping slider 308 is movably sleeved on the outer surface of the slide rail 305, and the transducer 307 is installed on the outer surface of one side of the damping slider 308 by bolts, the bottom of the cutting frame 301 is fixedly installed on the top of the cutting table 1, a PLC control system 6 is provided on the front surface of the top of the cutting table 1, a mounting groove 7 is provided on the front surface of the cutting table 1, an ultrasonic generator 8 is provided on the bottom surface of the mounting groove 7, and a loading and conveying mechanism 10 is provided inside the cutting table 1.

[0041] In this embodiment, after the anti-sway assembly 4 constrains the steel strip cutting area, the hydraulic mechanism 302 is activated, pushing the isolation damping plate 303 downward, thereby causing the cutting blade 304 to move downward and cut the steel strip. During cutting, the ultrasonic generator 8 is activated, and the transducer 307 converts the high-frequency signal into ultrasonic vibrations, and efficiently transmits the vibration energy to the horn 306. The horn 306 amplifies the small amplitude of the transducer 307 to the large amplitude required by the cutting blade 304. The vibration is then transmitted to the blade of the cutting blade 304, generating a high-frequency micro-cutting effect, reducing the material's resistance to plastic deformation, effectively reducing the steel strip cutting force, and simultaneously reducing energy consumption. A cavitation effect is generated between the cutting edge and the material, preventing adhesion, which is beneficial for improving the cutting surface quality.

[0042] Furthermore, the transducer 307 is axially connected to the amplitude transformer 306, which is beneficial to improving the stability of the resonance system and minimizing energy loss; the amplitude transformer 306 is vertically distributed to the cutting knife 304, so that the vibration direction of the amplitude transformer 306 is coupled at 90 degrees to the cutting direction of the cutting knife 304, and the lateral vibration of the amplitude transformer 306 is converted into shear stress of the cutting knife 304, avoiding axial bending load, and forming a composite failure mode of "high-frequency micro-shear + hydraulic main cutting" at the blade of the cutting knife 304. Compared with axial coupling, the chip shape changes from continuous strip to debris, which is beneficial to improving chip removal efficiency.

[0043] The mechanism achieves the following effects and operates as follows: a coil of steel strip is delivered to the loading conveyor 10 via a feeding device. The strip then passes through the space between two anti-sway plates 402 and onto the discharge conveyor 2. When the strip reaches the required length on the discharge conveyor 2, both the discharge conveyor 2 and the loading conveyor 10 automatically pause. The cylinder 405 then activates, pushing the upper anti-sway plate 402 downward via the fixed frame 406, which in turn drives the two movable rows of teeth 407 downward. The two meshing adjustment gears 408 simultaneously rotate, driving the other two movable rows of teeth 407 upward, which in turn drives the lower anti-sway plate 402 upward, causing the upper and lower rows of rubber balls 404 to move relative to each other and contact the upper and lower surfaces of the steel strip. As the two anti-sway plates 402 move relative to each other, they also move the upper and lower air injection pipes 415, the first connecting pipe 418, and the first nozzle 419, pulling on the corresponding elastic hoses 416 to stretch and expand. Simultaneously, the gas injection equipment is activated, sequentially delivering high-pressure airflow to two gas injection pipes 415, an elastic hose 416, and a fixed pipe 417. The high-pressure airflow then enters a first connecting pipe 418 and a second connecting pipe 420, where it is blown vertically toward the upper and lower surfaces of the steel strip through vertically distributed first nozzles 419. Furthermore, the high-pressure airflow in the second connecting pipe 420 enters multiple telescopic hoses 421, where it is ejected vertically toward the upper and lower surfaces of the steel strip through vertically distributed second nozzles 422, creating three vertical airflow pressure constraints closer to the cutting point of the steel strip. The hydraulic mechanism 302 is activated, pushing the isolation damping plate 303 downward, causing the cutting blade 304 to move downward and cut the steel strip. During cutting, ultrasonic generator 8 is activated, and transducer 307 converts the high-frequency signal into ultrasonic vibrations, efficiently transmitting the vibration energy to horn 306. Horn 306 amplifies the small amplitude of transducer 307 to the large amplitude required by cutting blade 304. The vibration is then transmitted to the blade of cutting blade 304, producing a high-frequency micro-cutting effect. After cutting, cutting assembly 3 and anti-sway assembly 4 are reset, and then discharge conveyor mechanism 2 and loading conveyor mechanism 10 resume operation. The cut steel strip is discharged and conveyed through discharge conveyor mechanism 2. The dual-axis forward and reverse motor 507 is activated, driving the rotating rod 508 and the second gear 505 to rotate together, and driving the chain 504 and multiple first gears 503 to rotate. This in turn drives the limit shaft 502 and the tilt plate 501 to rotate, causing the six upper and lower second nozzle groups 422 to rotate together into an inclined state, transforming the original five vertical airflows into two inclined airflows combined with three inclined airflows.

[0044] Among them, the discharge conveying mechanism 2, hydraulic mechanism 302, amplitude rod 306, transducer 307, cylinder 405, dual-axis forward and reverse motor 507, ultrasonic generator 8, feeding conveying mechanism 10 and PLC control system 6 are all existing technologies, and their components and usage principles are all public technologies, so no further explanation will be given here.
