Description

Technical Field

[0001] The present application relates to the technical field of mechanical processing equipment, and in particular to a semi-automatic adjustable three-roller plate rolling machine. Background Art

[0002] As a common metal sheet processing equipment, three-roller plate rolling machine is widely used in the manufacturing industry to produce various round or arc-shaped workpieces. With the improvement of industrial automation, three-roller plate rolling machine plays an important role in improving production efficiency and reducing labor intensity. Traditional three-roller plate rolling machine mainly relies on manual operation to complete the plate rolling work, while modern three-roller plate rolling machine is gradually developing towards automation and intelligence to meet higher production needs.

[0003] In the existing three-roller plate rolling machines, in order to realize the plate rolling operation, a structure consisting of a fixed upper roller and two lower rollers is usually adopted. In order to adjust the curvature of the rolled plate, a lifting mechanism is generally set on the base to drive the upper roller to move up and down. However, this design has some shortcomings in actual use. For example, when the cylinder needs to be taken out of the machine after the plate rolling is completed, due to the limited space between the lower rollers, personnel are required to lift one end of the upper roller, and then take out the cylinder. This not only increases the labor intensity of the operator, but may also cause safety accidents due to improper operation.

[0004] With regard to the above-mentioned related technologies, the existing three-roller plate rolling machine has inconveniences in the process of taking out the cylinder, especially when the rolled plate has a large diameter or a heavy weight, it is inconvenient for personnel to take out the cylinder. Therefore, how to design a device that can conveniently and quickly take out the rolled cylinder from the three-roller plate rolling machine has become a technical problem that needs to be solved urgently. Summary of the invention

[0005] In order to improve the problem that it is inconvenient for personnel to take out the cylinder, the present application provides a semi-automatic adjustable three-roller plate rolling machine.

[0006] The semi-automatic adjustable three-roller plate rolling machine provided in this application adopts the following technical solution: A semi-automatic adjustable three-roller plate rolling machine, comprising a supporting assembly, a material pressing assembly, a material pushing assembly and a connecting assembly, wherein the supporting assembly comprises a supporting frame, the material pressing assembly comprises two fixed seats, an upper roller, two lower rollers and a driving member, the two fixed seats are respectively connected to the two sides directly opposite to the supporting frame, the two ends of the upper roller are respectively rotatably connected to one of the fixed seats, the upper roller is vertically arranged with the fixed seat, the two lower rollers are both located on the side of the upper roller close to the supporting frame, the heights of the axes of the two lower rollers are flush, the two ends of the lower roller are respectively rotatably connected to one of the fixed seats, a rolling gap is left between the upper roller and the lower roller, the driving member is connected with the fixed seat, and the driving member is connected with the two lower rollers to drive the lower rollers to rotate; The pushing assembly is connected to the fixed seat, and the pushing assembly is used to push the cylinder to move. The connecting assembly includes a closing member, and a circular arc groove is opened on the top of one of the fixed seats for the cylinder to slide through. The fixed seat is divided into a fixed part fixed to the support frame and a connecting part not fixed to the support frame. The closing member includes a closing rod, and the closing rod is located at the circular arc groove. One end of the closing rod is rotatably connected to the fixed part, and the other end is used to support the connecting part. The pushing assembly is connected to the closing rod to drive the closing rod to rotate.

[0007] By adopting the above technical scheme, when it is necessary to use the semi-automatic adjustable three-roller plate rolling machine, first, the plate is moved to the side of the semi-automatic adjustable three-roller plate rolling machine, the driving member drives the lower roller to rotate, and the personnel extends one end of the plate into the coil gap. As the lower roller rotates, the plate can be rolled into a cylinder. Then, the pushing assembly is started, and the pushing assembly pushes the cylinder to move. During this process, the pushing assembly drives the closing rod to rotate, so that the cylinder slides out through the arc groove, and there is no need for personnel to lift one end of the upper roller. The semi-automatic adjustable three-roller plate rolling machine realizes the automation and efficiency of the plate rolling process; specifically, the support assembly provides a solid foundation for the entire equipment, and the setting of the driving member enables the lower roller to rotate stably, thereby realizing the rolling of the plate. The pushing assembly can automatically push the rolled cylinder out of the coil gap, reducing the labor intensity and safety risks of manual operation, and facilitating the improvement of the problem that it is inconvenient for personnel to take out the cylinder. The closing member in the connecting assembly can automatically open the arc groove during the cylinder push-out process, further improving the automation level and work efficiency of the equipment.

[0008] In a specific possible implementation scheme, the connecting assembly also includes a rotating member and two telescopic members, the fixed seat with the arc groove is provided with a accommodating cavity, the rotating member is located in the accommodating cavity, the rotating member includes a rotating rod, a first gear, a hoisting rod and a rotating wheel, the rotating rod is rotatably connected to the fixed seat, the rotating rod is arranged parallel to the support frame, the rotating axis of the rotating rod is perpendicular to the axis of the lower roller, the first gear is coaxially fixed to the rotating rod, the hoisting rod is rotatably connected to the fixed seat, the hoisting rod is arranged parallel to the rotating rod, the rotating wheel is coaxially fixed to the hoisting rod, the two telescopic members are respectively connected to one side of the rotating wheel, and the two telescopic members are symmetrically arranged along the diameter direction of the rotating wheel perpendicular to the support frame, when the closing rod is rotated to a certain angle, the rotating wheel is not meshed with the first gear, and the cylinder can slide out through the arc groove, the telescopic member is used to fix the rotating wheel and the fixed seat, and the pushing assembly is connected to the rotating rod to drive the rotating rod to rotate; The closing member also includes a fixing rope, one end of which is connected to the closing rod, and the other end of which is passed through the fixing seat, extends into the accommodating cavity, and is connected to the hoisting rod.

[0009] By adopting the above technical scheme, the semi-automatic adjustable three-roller plate rolling machine can push the cylinder through the pushing assembly after the plate rolling is completed, and at the same time drive the closing part to rotate the closing rod, thereby opening the arc groove to facilitate the smooth sliding of the cylinder. The rotating rod, the first gear, the hoisting rod and the rotating wheel in the rotating part work together to ensure that the closing rod is disengaged at an appropriate angle to avoid hindering the sliding out process of the cylinder; the design of the telescopic part enables the rotating wheel to be fixed in a specific position. When the closing rod is rotated to an appropriate angle, the rotating wheel stops rotating. At this time, the pushing assembly continues to push the cylinder to move, ensuring the stability and reliability of the closing rod. The setting of the fixed rope further ensures the consistency of the movement of the closing rod, thereby improving the coordination and safety of the entire system.

[0010] In a specific possible implementation scheme, the pushing assembly includes a power member and a pushing piece, the power member includes a pushing motor and a pushing screw, the housing of the pushing motor is fixed to the fixed seat without the accommodating cavity, the setting direction of the pushing screw is parallel to the axial direction of the lower roller, the pushing screw is close to the rotation gap, the output shaft of the pushing motor is coaxially fixed to one end of the pushing screw through a coupling, the other end of the pushing screw extends into the accommodating cavity, the pushing screw is rotatably connected to the fixed seat, the pushing piece is threadedly connected to the pushing screw, and the pushing piece is used to push the cylinder; The rotating member further comprises a first bevel gear and a second bevel gear, wherein the first bevel gear is coaxially fixed to one end of the pushing screw rod located in the accommodating cavity, and the second bevel gear is coaxially fixed to the rotating rod, and the first bevel gear and the second bevel gear are meshed.

[0011] By adopting the above technical solution, the driving motor drives the pushing screw to rotate, driving the pushing piece to slide back and forth along the length direction of the pushing screw, thereby effectively pushing the cylinder to move, improving the efficiency of cylinder removal, and reducing the labor intensity of operators. At the same time, the meshing design of the first bevel gear and the second bevel gear enables the rotation of the pushing screw to be transmitted to the rotating rod, further driving the closing rod to rotate, realizing the opening and closing of the arc groove, and ensuring the smooth removal of the cylinder.

[0012] In a specific feasible implementation scheme, the telescopic member includes an insertion rod, a sliding rod and a spring, one end of the insertion rod is fixed to a side of the rotating wheel that is not provided with teeth, the insertion rod is arranged from the rotating wheel toward the side away from the rotating wheel, the end of the insertion rod away from the rotating wheel is hollow, one end of the sliding rod is inserted into the end of the insertion rod away from the rotating wheel, the sliding rod is slidably connected to the insertion rod along the length direction of the insertion rod, the spring is located in the insertion rod, one end of the spring is fixed to the sliding rod, and the other end is fixed to the insertion rod, the fixing seat is provided with a guide groove in the accommodating cavity for the sliding rod to slide, the fixing seat is provided with a fixing groove in the accommodating cavity for the sliding rod to be inserted, and the guide groove is connected to the fixing groove.

[0013] By adopting the above technical solution, the telescopic part can effectively control the position of the rotating wheel to ensure the locking and release of the closing rod at a specific angle. Specifically, when the first gear is engaged with the teeth on the rotating wheel, the rotating wheel drives the sliding rod to slide out of the fixed groove. At this time, the spring is in a compressed state. When the first gear is disengaged from the teeth on the rotating wheel, the sliding rod is quickly inserted into the fixed groove under the action of the spring, thereby fixing the rotating wheel. This mechanism ensures that the closing rod can accurately rotate to the specified angle when the arc groove needs to be opened, and can quickly return to its position when the arc groove needs to be closed, thereby improving the safety and reliability of operation.

[0014] In a specific feasible implementation scheme, the closing member also includes a rotating rod, a closing wheel and a torsion spring, the fixed seat is provided with a rotating groove at the arc groove, the rotating groove is located in the fixed part, the rotating rod is located in the rotating groove, the setting direction of the rotating rod is consistent with the setting direction of the hoisting rod, both ends of the rotating rod are rotatably connected to the fixed seat, the closing wheel is coaxially fixed to the rotating rod, the torsion spring is sleeved on one end of the rotating rod, one end of the torsion spring is fixed to the fixed seat, and the other end is fixed to the rotating rod.

[0015] By adopting the above technical solution, the arrangement of the rotating rod, closing wheel and torsion spring in the closing member allows the closing rod to automatically open when the cylinder slides through the arc groove, and automatically close after the cylinder is completely moved out. Specifically, when the pushing assembly drives the closing rod to rotate to a certain angle, the closing wheel disengages from the rotating gear, and the rotating rod maintains a rotating state under the action of the torsion spring, so that the closing rod is in an open position, which facilitates the sliding out of the cylinder. When the cylinder is completely moved out, the torsion spring restores its deformation, drives the closing rod to reset, and the closing wheel re-engages with the rotating gear, so that the closing rod returns to the closed position, ensuring the safety of the cylinder after it slides out.

[0016] In a specific possible implementation manner, the end of the sliding rod away from the insertion rod is configured as a round head.

[0017] By adopting the above technical solution, the friction resistance of the slide bar in the guide groove can be reduced, making it slide more smoothly, while avoiding damage or jamming of the slide bar due to the sharp end during the sliding process, thereby improving the reliability and service life of the device.

[0018] In a specific possible implementation scheme, the pushing member includes a sliding seat and a push plate, the sliding seat is threadedly connected to the pushing screw, the sliding seat slides back and forth on the pushing screw along the length direction of the pushing screw, the push plate is fixed to the top of the sliding seat, the other end of the push plate extends into the rotating gap and the winding gap in turn, and the push plate is used to push the cylinder.

[0019] By adopting the above technical solution, the sliding seat is threadedly connected to the pushing screw and slides back and forth on the pushing screw along its length direction, ensuring that the push plate can accurately control the movement trajectory. The push plate is fixed to the top of the sliding seat, and one end of the push plate extends into the rotating gap and the coil gap in turn, effectively avoiding the push plate from deviating during the pushing process and ensuring the smooth movement of the cylinder. The design of the push plate also increases the friction force with the contact surface of the cylinder, further improving the stability of the pushing process and reducing the safety hazards caused by sliding.

[0020] In a specific possible implementation scheme, the connecting assembly also includes a rotating part, which includes a guide rod, two sprockets, a chain and a rotating gear. The guide rod is located on the side of the closing rod close to the support frame, and the guide rod is arranged parallel to the closing rod. Both ends of the guide rod are rotatably connected to the fixed seat, one of the sprockets is coaxially fixed to the rotating rod, and the other sprocket is coaxially fixed to the guide rod. The chain is wound between the two sprockets, and the rotating gear is coaxially fixed to the guide rod. The rotating gear is close to the closing wheel, and the side wall of the closing wheel is provided with a plurality of teeth meshing with the rotating gear, and the teeth occupy one quarter of the circumference of the closing wheel. When the closing rod rotates a certain angle, the closing wheel does not mesh with the rotating gear.

[0021] By adopting the above technical solution, when the closing rod is rotated to a certain angle, the closing wheel does not mesh with the rotating gear, so that the closing rod can rotate freely, making it easy for the cylinder to slide through the arc groove and be removed smoothly; at the same time, the coordinated use of the guide rod, sprocket, chain and rotating gear can further drive the closing rod to rotate, thereby ensuring the stability and reliability of the closing rod and improving the automation level and work efficiency of the entire device.

[0022] In a specific possible implementation scheme, the closing member also includes two magnets, and the fixing seat is provided with a fitting groove at the connecting portion for placing the closing rod, one of the magnets is fixed in the fitting groove, and the other magnet is fixed to the end of the closing rod away from the closing wheel, and when the closing rod is located in the fitting groove, the two magnets are magnetically attracted to each other.

[0023] By adopting the above technical solution, when the closing rod is located in the fitting groove, the two magnets are attracted to each other, so that the closing rod is firmly fixed in the fitting groove, effectively preventing the closing rod from accidentally loosening due to external vibration or other factors, ensuring the closed state of the arc groove, and improving the safety and reliability of the cylinder sliding out process; at the same time, the attraction force of the magnet also enables the closing rod to be quickly released when it needs to be opened, simplifying the operation process and improving work efficiency.

[0024] In a specific possible implementation mode, the fixing seat is provided with a plurality of balls at the arc groove, and the balls are rotatably connected to the fixing portion.

[0025] By adopting the above technical solution, the friction resistance between the cylinder and the fixed seat is effectively reduced, making the cylinder smoother when sliding out of the arc groove, reducing the labor intensity of operators and improving work efficiency. At the same time, the ball design can also extend the service life of the fixed seat, reduce wear caused by frequent use, and ensure long-term stable operation of the equipment.

[0026] In summary, the present application includes at least one of the following beneficial technical effects: 1. The semi-automatic adjustable three-roller plate rolling machine designed realizes the automation and efficiency of the plate rolling process; specifically, the support assembly provides a solid foundation for the entire equipment, the setting of the drive component enables the lower roller to rotate stably, thereby realizing the rolling of the plate, and the pushing assembly can automatically push the rolled cylinder out of the coil gap, reducing the labor intensity and safety risks of manual operation, and facilitating the improvement of the problem that it is inconvenient for personnel to take out the cylinder. The closing member in the connecting assembly can automatically open the arc groove during the cylinder pushing process, further improving the automation degree and work efficiency of the equipment.

[0027] 2. The semi-automatic adjustable three-roller plate rolling machine is designed with a telescopic part that allows the rotating wheel to be fixed in a specific position. When the closing rod is rotated to an appropriate angle, the rotating wheel stops rotating. At this time, the pushing assembly continues to push the cylinder to ensure the stability and reliability of the closing rod. The setting of the fixed rope further ensures the consistency of the movement of the closing rod and improves the coordination and safety of the entire system.

[0028] 3. The semi-automatic adjustable three-roller plate rolling machine is designed.

The setting direction of the rotating rod 431 is consistent with the setting direction of the hoisting rod 415. Both ends of the rotating rod 431 are rotatably connected to the fixed seat 21. The closing wheel 432 is coaxially welded to the rotating rod 431. One end of the closing rod 433 is welded to the outer side of the closing wheel 432, and the other end is close to the connecting part. The fixed seat 21 is provided with a fitting groove 218 for placing the closing rod 433 at the connecting part, and one of the magnets 434 is fixedly connected to the fitting groove 218 by a screw, and the other magnet 434 is fixedly connected to the closing rod 433 by a screw away from the closing rod 433. At one end of the closing wheel 432, when the closing rod 433 is located in the fitting groove 218, the two magnets 434 are attracted to each other, and the closing rod 433 supports the connection part. The torsion spring 435 is sleeved on one end of the rotating rod 431. One end of the torsion spring 435 is welded to the fixing seat 21, and the other end is welded to the rotating rod 431. One end of the fixing rope 436 is fixedly connected to the closing rod 433 by binding, and the other end is passed through the pulley 437 and extends into the accommodating cavity 212 and is fixedly connected to the hoisting rod 415 by binding. The pulley 437 is fixedly connected to the fixing seat 21 by screws. When the hoisting rod 415 rotates, the fixing rope 436 can be wound around the hoisting rod 415. In this way, the closing rod 433 is pulled to rotate toward the side away from the fixed seat 21. When the closing rod 433 rotates a specified angle, such as 90 degrees, the specific angle is determined according to design requirements, so that the cylinder can slide through the arc groove 215. At this time, the torsion spring 435 has elastic potential energy, and the sliding rod 422 extends into the fixed groove 214 to fix the rotating wheel 416, thereby stopping the rotation of the winch rod 415; conversely, the first gear 414 reverses to drive the rotating wheel 416 to rotate, and the torsion spring 435 restores its deformation, so that the closing rod 433 is located in the fitting groove 218. At this time, the sliding rod 422 located on the other side of the rotating wheel 416 is inserted into the fixed groove 214.

[0050] Reference Figure 7The connecting assembly 4 also includes a rotating member 44, which includes a guide rod 441, two sprocket wheels 442, a chain 443 and a rotating gear 444. The guide rod 441 is located on the side of the closing rod 433 close to the support frame 11. The guide rod 441 is arranged parallel to the closing rod 433. Both ends of the guide rod 441 are rotatably connected to the fixed seat 21. One of the sprocket wheels 442 is coaxially welded to the rotating rod 412, and the other sprocket wheel 442 is coaxially welded to the guide rod 441. The chain 443 is wound around the two sprocket wheels 442. The rotating gear 444 is coaxially welded to the guide rod 441, and the rotating gear 444 is close to the closing rod 433. The closing wheel 432 has a plurality of teeth meshing with the rotating gear 444 on its side wall, and the teeth occupy one quarter of the circumference of the closing wheel 432. When the closing rod 433 rotates a specified angle, the closing wheel 432 does not mesh with the rotating gear 444. When a person removes the cylinder, the screw rod 312 is pushed to drive the first gear 414 to rotate, and the first gear 414 drives the rotating rod 412 to rotate, which enables the sprocket 442 to drive the guide rod 441 to rotate. At this time, the rotating gear 444 is meshed with the closing wheel 432, and the first gear 414 drives the closing wheel 432 to rotate, so that the hoisting rod 415 rotates, which facilitates driving the closing rod 433 to rotate.

[0051] The implementation principle of a semi-automatic adjustable three-roller plate rolling machine in an embodiment of the present application is as follows: when the semi-automatic adjustable three-roller plate rolling machine is needed, first, the plate is moved to the side of the semi-automatic adjustable three-roller plate rolling machine, and the lifting member 25 in the pressing assembly 2 is started. According to the design requirements, the lifting member 25 adjusts the upper roller 22 to a suitable position, and then starts the driving member 24, and the driving member 24 drives the lower roller 23 to rotate. The personnel extends one end of the plate into the rolling gap, and as the lower roller 23 rotates, the plate can be rolled into a cylinder; when the cylinder needs to be removed, the personnel starts the power member 31, and the power member 31 drives the push plate 322 to move, and the push plate 322 can push the cylinder to move. During the movement of the power member 31, the power member 31 drives the closing member 43 in the connecting assembly 4 to open the arc groove 215, so that the cylinder slides through the arc groove 215 until the cylinder is separated from the upper roller 22, and the personnel removes the cylinder.

[0052] When the power part 31 is started, the pushing motor 311 drives the pushing screw 312 to rotate, which can drive the pushing plate 322 to push the cylinder to move. At this time, the first bevel gear 411 rotates with the pushing screw 312, which can drive the rotating rod 412 to rotate. At the same time, the sprocket 442 and the first gear 414 both rotate with the rotating rod 412. The first gear 414 drives the hoisting rod 415 to rotate, which can pull the closing rod 433 to rotate. The sprocket 442 drives the rotating gear 444 to rotate through the guide rod 441, which can drive the closing wheel 432 to rotate, thereby rotating the closing rod 433.

[0053] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereto. Therefore, any equivalent changes made according to the structure, shape, and principle of the present application should be included in the protection scope of the present application.
