[0017] The present invention also provides a method for using the bending and cutting device for processing fitness equipment, comprising the following steps:

[0018] S1. Place the pipe to be processed between two first clamping plates and two second clamping plates.

[0019] S2. The telescopic rod of the electric hydraulic push rod drives the horizontal plate to move downward, and then drives the related components to move synchronously, so that the pipe fitting moves toward the first bending fixture and the second bending fixture under the drive of the conveying plate. When one end of the conveying plate is in contact with the limit baffle, the conveying plate stops moving to complete the initial positioning.

[0020] S3. As the horizontal plate continues to move, the two linked optical axes move downward, so that the side plate drives the first bending fixture and the second bending fixture to move in opposite directions. When the first bending fixture and the second bending fixture move to the surface of the conveying plate and are located between the second clamping plate and the first clamping plate, the extrusion and bending process of the pipe is realized under the action of the outer shape of the adjacent surface of the first bending fixture and the second bending fixture.

[0021] S4.

When the cross plate moves to the initial position, the restriction on the movement of the conveying plate is released, and the conveying plate drives the bent pipe to move and reset under the action of gravity.

[0022] S5. During the extension and retraction of the telescopic end of the electric hydraulic push rod, the relevant parts move together. When specific conditions are met, the pipe cutting process is started. Through the coordinated action of the touch switch, cutting motor, cutting blade, etc., the pipe cutting process on the surface of the conveying plate is realized.

[0023] Compared with the prior art, the invention has the following beneficial effects: the invention has a scientific and reasonable structure and is safe and convenient to use:

[0024] It is beneficial that when the telescopic end of the electric hydraulic push rod is extended, the conveying plate drives the pipe to move between the first bending fixture and the second bending fixture. At the same time, after the pipe moves a certain distance, the first bending fixture and the second bending fixture move toward the direction of the pipe at the same time, and after the pipe is moved to a suitable position, the pipe stops moving. Under the action of the shape of the adjacent surfaces of the first bending fixture and the second bending fixture, the bending process of the pipe is realized. When the telescopic end of the electric hydraulic push rod is retracted, the positions of the first bending fixture and the second bending fixture do not change, thereby ensuring the bending effect of the pipe. At the same time, the conveying plate is equipped with The clamping of the first bending clamp and the second bending clamp does not move, and after the telescopic end of the electric hydraulic push rod moves to the initial position, the first bending clamp and the second bending clamp start to move in the direction away from each other, and after the first bending clamp and the second bending clamp move in the direction away from each other to a suitable position, the conveying plate drives the pipe to move out from the inside of the U-shaped bracket, thereby realizing convenient placement and removal of the pipe, improving the use effect of the device, and being conducive to automatically cutting the end of the pipe when bending the pipe, avoiding the problem of poor cutting effect caused by loose fixation of the pipe during the cutting process.

[0053] A conveying plate 69 is arranged in the conveying groove opened on the upper surface of the U-shaped base 1, and the conveying plate 69 is slidably connected to the U-shaped base 1. A limited stopper 67 is fixedly connected to the upper surface of the U-shaped base 1. A bearing plate 619 is fixedly connected to the upper surface of the U-shaped base 1. A rotating shaft 620 is inserted into the rotating groove opened inside the bearing plate 619. The rotating shaft 620 is rotatably connected to the bearing plate 619 through a bearing. A second gear 621 and a first gear 68 are fixedly sleeved on the surface of the rotating shaft 620. The second gear 621 is located between the first gear and the second gear. The second gear 621 is meshed with the gear rod 65 between the wheel 68 and the carrier plate 619. A clearance groove 618 is provided on the upper surface of the U-shaped base 1. The clearance groove 618 is located below the gear rod 65. The setting of the clearance groove 618 facilitates the gear rod 65 to move downward, thereby avoiding the gear rod 65 from being blocked from moving downward, and then driving the conveying plate 69 to move during the movement of the gear rod 65. The upper surface of the conveying plate 69 is equidistantly provided with tooth grooves 610. The first gear 68 is meshed with the conveying plate 69 through the equidistantly arranged tooth grooves 610. The upper surface of the conveying plate 69 is fixedly connected with two first clamping plates 622 and two second clamping plates 623, the gravity of the second counterweight block 611 is greater than the resistance encountered during the movement of the conveying plate 69, and when the second counterweight block 611 drives the first rectangular sliding sleeve 64 to move downward, the first counterweight block 61 can be pulled upward by the pull rope 62, that is, in the absence of external force, the gravity of the second counterweight block 611 itself can drive the first rectangular sliding sleeve 64 to move downward and make the first counterweight block 61 move upward, and The conveying plate 69 is driven to slide on the surface of the U-shaped base 1. When the conveying plate 69 and the limit baffle 67 are in contact with each other, making the conveying plate 69 unable to move, the second rectangular sliding sleeve 616 moves downward to make the second slide plate 614 slide inside the yielding groove 615. At this time, the second counterweight block 611 and the upper surface of the first rectangular sliding sleeve 64 are in contact with each other, thereby avoiding the problem of the conveying plate 69 being blocked from moving and then stuck due to the first bending clamp 47 and the second bending clamp 48 squeezing the pipe during the bending process.

[0054] The present invention also provides a method for using the bending and cutting device for processing fitness equipment, comprising the following steps:

[0055] S1. Place the pipe to be processed between two first clamping plates 622 and two second clamping plates 623.

[0056] S2. The telescopic rod of the electric hydraulic push rod 41 drives the horizontal plate 42 to move downward, and then drives the related components to move synchronously, so that the pipe fitting moves toward the first bending fixture 47 and the second bending fixture 48 under the drive of the conveying plate 69. When one end of the conveying plate 69 is in contact with the limit baffle 67, the conveying plate 69 stops moving to complete the initial positioning.

[0057] S3. As the horizontal plate 42 continues to move, the two linked optical axes 422 move downward, so that the side plate 43 drives the first bending fixture 47 and the second bending fixture 48 to move in opposite directions. When the first bending fixture 47 and the second bending fixture 48 move to the surface of the conveying plate 69 and are located between the second clamping plate 623 and the first clamping plate 622, the extrusion and bending process of the pipe fitting is realized under the action of the outer shape of the adjacent surface of the first bending fixture 47 and the second bending fixture 48.

[0058] S4. When the first bending fixture 47 and the second bending fixture 48 complete the bending process of the pipe, the telescopic end of the electric hydraulic push rod 41 begins to retract, driving the relevant components to reset. When the cross plate 42 moves to the initial position, the restriction on the movement of the conveying plate 69 is released, and under the action of gravity, the conveying plate 69 drives the bent pipe to move and reset.

[0059] S5. During the extension and retraction of the telescopic end of the electric hydraulic push rod 41, the relevant parts move together. When specific conditions are met, the pipe cutting process is started. Through the coordinated action of the touch switch 517, the cutting motor 520, the cutting blade 519, etc., the pipe cutting process on the surface of the conveying plate 69 is realized.

[0060] Working principle: When the bending and cutting device is in use, the device is connected to an external power source, and the pipe to be processed is placed between the two first clamping plates 622 and the two second clamping plates 623, so as to facilitate the movement of the pipe during the bending process;

[0061] The operating controller starts the electric hydraulic push rod 41. The operation of the electric hydraulic push rod 41 drives the horizontal plate 42 to move downward. The movement of the horizontal plate 42 drives the second fixed connecting plate 617 and the two linkage optical axes 422 to move synchronously.

[0062] In the process of the second fixed connecting plate 617 moving downward, it drives the second rectangular sliding sleeve 616 to move downward synchronously, and under the action of the gravity of the second counterweight block 611, it drives the first rectangular sliding sleeve 64 to slide downward on the surface of the L-shaped slide plate 63, and the movement of the first rectangular sliding sleeve 64 drives the gear rod 65 to move synchronously, and the movement of the gear rod 65 drives the second gear 621 meshed with it to rotate, and then drives the first gear 68 to rotate through the rotating shaft 620, and the rotation of the first gear 68 drives the conveying plate 69 to slide on the surface of the U-shaped base 1 under the action of the equidistant tooth grooves 610, and the movement of the conveying plate 69 drives the pipe fittings on its surface to move synchronously toward the first bending fixture 47 and the second bending fixture 48, and in the first rectangular sliding sleeve 64, the gear rod 65 moves synchronously, and the gear rod 65 drives the second gear 621 meshed with it to rotate, and then drives the first gear 68 to rotate through the rotating shaft 620, and the rotation of the first gear 68 drives the conveying plate 69 to slide on the surface of the U-shaped base 1 under the action of the equidistant tooth grooves 610, and the movement of the conveying plate 69 drives the pipe fittings on its surface to move synchronously toward the first bending fixture 47 and the second bending fixture 48. During the downward movement of the sliding sleeve 64, the first counterweight 61 is pulled upward by the pull rope 62. When one end of the conveying plate 69 is in contact with the limit stopper 67, the conveying plate 69 cannot move. The conveying plate 69 stops moving, causing the first gear 68 to stop rotating. The second gear 621 stops rotating through the rotating shaft 620, and then the gear rod 65 cannot slide downward, that is, the first rectangular sliding sleeve 64 cannot continue to move. At this time, the cross plate 42 drives the second rectangular sliding sleeve 616 to continue to move downward. Under the blocking effect of the first rectangular sliding sleeve 64, the second counterweight 611 cannot continue to move with the second rectangular sliding sleeve 616, so that the second slide plate 614 slides inside the yielding slot 615.

[0063] During the downward movement of the two linkage optical axes 422, the linkage optical axis 422 slides against the side of the built-in right-angled trapezoidal building block 45 close to the U-shaped bracket 2, and moves from the side of the built-in right-angled trapezoidal building block 45 to the bottom of the built-in right-angled trapezoidal building block 45. Under the restriction of the shape of the built-in mounting groove 46, the linkage optical axis 422 slides against the bottom surface of the built-in right-angled trapezoidal building block 45.

[0064] When the linkage optical axis 422 is in contact with the built-in right-angled trapezoidal building block 45 and slides close to one side of the U-shaped bracket 2, the position of the side plate 43 does not change during this process. When the linkage optical axis 422 moves to the bottom surface of the built-in right-angled trapezoidal building block 45, the two side plates 43 move in the direction close to the U-shaped bracket 2 under the action of the shape of the built-in mounting groove 46 and the inclined surface of the bottom surface of the built-in right-angled trapezoidal building block 45. As the cross plate 42 moves, the side plates 43 continue to move in the direction close to the U-shaped bracket 2. During the movement of the side plates 43, the horizontal slide plate 44 is driven to move synchronously, thereby driving the first bending fixture 47 and the second bending fixture 48 to move in opposite directions. In this process, when the first bending fixture 47 and the second bending fixture 48 move When the first and second bending jigs 47 and 48 move to the surface of the conveying plate 69, the first bending jig 47 and the second bending jig 48 are located between the second clamping plate 623 and the first clamping plate 622, and the conveying plate 69 cannot move due to the obstruction of the limit stopper 67. With the continuous movement of the first and second bending jigs 47 and 48, the extrusion and bending process of the pipe fitting is realized under the action of the shape of the adjacent surface of the first and second bending jigs 47 and 48, and the conveying plate 69 stops moving during the extrusion and bending of the pipe fitting. When the second bending jig 48 and the first bending jig 47 move on the surface of the conveying plate 69 to bend the pipe fitting, the two sides of the first and second bending jigs 47 and 48 are just in contact with the surfaces of the first and second clamping plates 622 and 623.

[0065] As the horizontal plate 42 moves downward and the side plate 43 moves toward the direction close to the U-shaped bracket 2, when the bottom surface of the horizontal plate 42 fits against the top of the limiting rod 416, the limiting rod 416 is driven to move downward synchronously with the movement of the horizontal plate 42. At this time, the limiting rod 416 slides inside the second limiting slot 423, and the side plate 43 drives the horizontal slide plate 44 to move synchronously in the direction of the U-shaped bracket 2. At this time, the limiting rod 416 moves downward and slides on the bottom surface of the horizontal plate 42. The limiting rod 416 drives the rectangular plate 414 to move synchronously during its sliding inside the second limiting slot 423, and drives the spring 415 to stretch during the movement of the rectangular plate 414. When the first bending fixture 47 and the second bending fixture 48 complete the bending process of the pipe fitting, , that is, the linkage optical axis 422 at the end of the horizontal plate 42 just moves to the side close to the built-in right-angled trapezoidal building block 45 away from the U-shaped bracket 2, and the limiting rod 416 at this time just moves to the position of the first limiting slot 413, and under the action of the elastic potential energy of the spring 415, the limiting rod 416 slides into the inside of the first limiting slot 413, and the size of the first limiting slot 413 is adapted to the shape of the limiting rod 416, so that the limiting rod 416 can slide inside the first limiting slot 413, and at this time, the telescopic end of the electric hydraulic push rod 41 begins to retract, thereby driving the horizontal plate 42 to move upward, and the horizontal plate 42 drives the linkage optical axis 422 to slide on the side of the built-in right-angled trapezoidal building block 45 away from the U-shaped bracket 2 during the upward movement, and the position of the side plate 43 does not move during this process;

[0066] In the process of the horizontal plate 42 driving the second fixed connecting plate 617 and the second rectangular sliding sleeve 616 to move upward synchronously, when the second rectangular sliding sleeve 616 moves to fit the bottom surface of the second counterweight block 611, the second sliding plate 614 is inserted into the inside of the giving way slot 615, and the movement of the second rectangular sliding sleeve 616 drives the second counterweight block 611 to move upward synchronously until the horizontal plate 42 moves to the initial position and stops, and the distance between the second counterweight block 611 and the first rectangular sliding sleeve 64 is constantly increasing;

[0067] When the side plate 43 moves toward the direction close to the U-shaped bracket 2, the longitudinal sliding sleeve 421 is driven by the first connecting rod 417 to slide upward on the surface of the longitudinal sliding rod 420. When the horizontal plate 42 moves to the initial position, that is, the linkage optical axis 422 moves to the upper surface close to the built-in right-angle trapezoidal building block 45, the side plate 43 is pushed by the first connecting rod 417 to move away from the U-shaped bracket 2 under the action of the gravity of the longitudinal sliding sleeve 421.

[0068] In this process, the movement of the side plate 43 drives the transverse slide plate 44 to move, thereby causing the first bending fixture 47 and the second bending fixture 48 to move away from each other. When the first bending fixture 47 and the second bending fixture 48 slide out from the surfaces of the first clamping plate 622 and the second clamping plate 623, the restriction on the movement of the conveying plate 69 is released, and the first rectangular sliding sleeve 64 is pulled upward by the pull rope 62 under the action of the gravity of the first counterweight block 61, thereby driving the gear rod 65 to move upward, and under the action of the second gear 621, the conveying plate 69 is driven to move in the direction away from the limit baffle 67 until the conveying plate 69 moves to the initial position;

[0069] It is beneficial for the conveying plate 69 to drive the pipe to move between the first bending fixture 47 and the second bending fixture 48 when the telescopic end of the electric hydraulic push rod 41 is extended. At the same time, after the pipe moves a certain distance, the first bending fixture 47 and the second bending fixture 48 move toward the pipe at the same time, and after the pipe moves to a suitable position, the pipe stops moving. Under the action of the shape of the adjacent surface of the first bending fixture 47 and the second bending fixture 48, the bending process of the pipe is realized. When the telescopic end of the electric hydraulic push rod 41 is retracted, the first bending fixture 47 and the second bending fixture 48 are The position does not change, ensuring the bending effect of the pipe fitting, and at the same time, the conveying plate 69 cooperates with the clamping of the first bending fixture 47 and the second bending fixture 48 without moving. After the telescopic end of the electric hydraulic push rod 41 moves to the initial position, the first bending fixture 47 and the second bending fixture 48 begin to move away from each other, and after the first bending fixture 47 and the second bending fixture 48 move to a suitable position in the direction away from each other, the conveying plate 69 drives the pipe fitting to move out from the inside of the U-shaped bracket 2, thereby realizing convenient placement and removal of the pipe fitting, thereby improving the use effect of the device;

[0070] When the telescopic end of the electric hydraulic push rod 41 is extended, its telescopic rod drives the cross plate 42 to move downward, because the linkage optical axis 422 slides against the side of the built-in right-angled trapezoidal building block 45 close to the U-shaped bracket 2, the side plate 43 does not move at this time, so that the longitudinal sliding sleeve 421 does not move, and the movement of the cross plate 42 drives the rectangular pressing plate 512 to move synchronously. When the linkage optical axis 422 moves to a position close to the bottom surface of the built-in right-angled trapezoidal building block 45, the rectangular pressing plate 512 moves to a position flush with the roller 59, and as the cross plate 42 moves, the longitudinal sliding sleeve 421 moves upward, and the movement of the longitudinal sliding sleeve 421 drives the counterweight rod 515 to move upward, thereby The second connecting rod 511 pulls the transverse connecting plate 58 to move toward the direction close to the U-shaped bracket 2. The movement of the transverse connecting plate 58 drives the special-shaped slide plate 51 to slide inside the top extension plate 3, so that the roller 59 moves to the top of the rectangular pressing plate 512. When the special-shaped slide plate 51 moves toward the direction of the U-shaped bracket 2, it drives the L-shaped mounting plate 53 and the cutting motor 520 to move synchronously until the linkage optical axis 422 moves to the side close to the built-in right-angle trapezoidal building block 45 away from the U-shaped bracket 2 so that the side plate 43 stops moving, and then the counterweight rod 515 and the longitudinal sliding sleeve 421 stop moving upward. At this time, the special-shaped slide plate 51 and the cutting auxiliary plate 57 stop moving.

[0071] When the telescopic end of the electric hydraulic push rod 41 retracts and drives the cross plate 42 to move upward, the movement of the cross plate 42 drives the rectangular pressing plate 512 to move upward. Since the position of the side plate 43 does not change at this time, the positions of the cutting auxiliary plate 57 and the special-shaped slide plate 51 do not change. When the rectangular pressing plate 512 contacts the surface of the roller 59, the movement of the rectangular pressing plate 512 drives the cutting auxiliary plate 57 to rotate on the surface of the auxiliary rotating shaft 523, thereby driving the first optical axis 55 to move downward, thereby pushing the L-shaped mounting plate 53 in the mounting groove 54. The first bending fixture 47 and the second bending fixture 48 are in a state of clamping the pipe during the pipe cutting process, thereby ensuring the effect of pipe cutting. When the touch switch 517 is not in contact with the touch plate 518, the cutting motor 520 is operated, thereby driving the cutting blade 519 to rotate. The cutting blade 519 rotates and moves downward, thereby realizing the process of cutting the pipe on the surface of the conveying plate 69.

[0072] When the telescopic end of the electric hydraulic push rod 41 drives the horizontal plate 42 to move to the initial position, the longitudinal sliding sleeve 421 moves downward, and drives the special-shaped slide plate 51 to move away from the U-shaped bracket 2 under the action of the second connecting rod 511. When the roller 59 slides out from the surface of the rectangular pressing plate 512, the L-shaped mounting plate 53 drives the cutting motor 520 to move under the action of the gravity of the square counterweight block 524 and moves to the initial position;

[0073] It is beneficial to automatically cut the end of the pipe when the pipe is bent, avoiding the problem of poor cutting effect caused by loose fixing of the pipe during the cutting process.
