Description

Technical Field

[0001] The present invention relates to the technical field of bending machines, in particular to a luggage tube bending machine. Background Art

[0002] During the manufacturing process of bags, the sealing strips on the edges of the shells usually need to be formed by bending the tubes to adapt to the designs of bags of different shapes.

[0003] At present, the sealing strips in the industry are generally bent manually, or with a simple machine combined with manual bending. Workers will become tired when bending the pipes for a long time, which makes the bending efficiency of luggage sealing strips low. Summary of the Invention

[0004] In order to improve the problem of low efficiency of workers in bending luggage sealing strips, the present application provides a luggage tube bending machine.

[0005] The present application provides a luggage tube bending machine that adopts the following technical solutions: The top of the piston rod of the motor is fixed with the top of the piston rod, and the top of the piston rod is fixed with the piston rod of the motor.

[0006] By adopting the above technical solution, the pipe fitting is inserted into the bending groove, and then the cylinder one is started, and the piston rod of the cylinder one drives the moving block to move toward the direction close to the rotating shaft, so that the moving block drives the clamping block to move toward the direction close to the rotating shaft, so that the clamping block presses the pipe fitting onto the bending ring, and then the pipe fitting is pressed onto the bending ring through the compacting assembly, and finally the motor is started, so that the output shaft of the motor drives the rotating shaft to rotate, and the rotating shaft drives the bending ring and the connecting plate to rotate at the same time, so that the bending ring and the connecting plate drive the pipe fitting to rotate and bend when they rotate, reducing the number of pipe fittings to bend by staff, thereby improving the bending efficiency of the pipe fittings.

[0007] Preferably, a groove is provided on the outer circumference of the bending ring, the groove is connected to the bending groove, a pressure block is fixed in the groove, and a plug-in groove is provided on the side of the pressure block close to the tightening block, and the plug-in groove is connected to the bending groove.

[0008] By adopting the above technical solution, when the pipe fitting is inserted into the bending groove, the pipe fitting is also inserted into the plug-in groove, and then cylinder one is started, so that the piston rod of cylinder one pushes the moving block to move toward the direction close to the rotating shaft, and the moving block drives the clamping block to move toward the direction close to the rotating shaft, so that the clamping block is pressed against the outer peripheral surface of the bending ring, and at the same time, the clamping block is pressed against the surface of the pressing block, thereby increasing the contact area between the clamping block and the pipe fitting, and then the clamping block presses the pipe fitting into the bending groove.

[0009] Preferably, the moving block includes a sliding block slidably arranged in the installation groove, the top surface of the sliding block is provided with a sliding groove, a slider is slidably arranged in the sliding groove, the pressing block is fixed to the side of the slider close to the rotating shaft, the top surface of the sliding block is fixed with a fixed block, the side of the fixed block is penetrated by a screw, the screw is threadedly connected to the fixed block, and the end of the screw close to the rotating shaft is rotatably installed on the side of the slider away from the rotating shaft.

[0010] By adopting the above technical solution, when the clamping block is used for a long time, the end face of the clamping block close to the rotating shaft will be worn, making it impossible for the clamping block to press the pipe fitting onto the bending ring. By rotating the screw, the screw pushes the slider to move, and the slider drives the clamping block to move toward the direction close to the rotating shaft, thereby making it easier for the clamping block to press the pipe fitting onto the bending ring.

[0011] Preferably, the compacting assembly includes a base arranged on the workbench, a slide rail is provided on the top surface of the base, a slide seat is provided on the upper sliding surface of the slide rail, a clamping block is provided on the end surface of the slide seat close to the rotating shaft, and a cylinder 2 is provided on the base, and the end of the piston rod of the cylinder 2 is fixedly connected to the side of the slide seat away from the rotating shaft.

[0012] By adopting the above technical solution, when the pipe fitting is inserted into the bending groove and is ready to be bent, cylinder two is started, and the piston rod of cylinder two drives the slide to move toward the direction close to the rotating shaft, so that the slide drives the clamping block to move toward the direction close to the rotating shaft, so that the clamping block presses the pipe fitting against the outer circumference of the bending ring. When the bending ring and the connecting plate rotate and drive the pipe fitting to rotate for bending, the possibility of the pipe fitting rotating at the end away from the rotating shaft is reduced, thereby facilitating the bending of the pipe fitting.

[0013] Preferably, a compacting block that cooperates with the pressing block is fixed on the top surface of the workbench, and the end face of the compacting block close to the rotating shaft is in contact with the outer peripheral surface of the bending ring. A slot for inserting pipes is provided on the side of the compacting block close to the pressing block, and the slot is connected to the bending groove.

[0014] By adopting the above technical solution, when the pipe fitting is inserted into the bending groove, the pipe fitting is also inserted into the notch. When cylinder two is started, the piston rod of cylinder two drives the slide to move toward the direction close to the rotating shaft, and the clamping block and the opposite side of the compacting block abut against each other, so that the pipe fitting is clamped between the compacting block and the clamping block, thereby making it easier to reduce the possibility of swinging of the end of the pipe fitting away from the rotating shaft when bending the pipe fitting.

[0015] Preferably, a movable groove is provided on the end face of the slide close to the rotating shaft, and the movable groove passes through the two end faces of the slide. A mounting block is slidingly arranged in the movable groove, and the clamping block is fixed to the side face of the mounting block close to the rotating shaft. Cylinder three is fixed to the side face of the slide, and the end of the output shaft of cylinder three is fixedly connected to the end face of the mounting block.

[0016] By adopting the above technical solution, when the bending ring and the clamping block rotate simultaneously to bend the pipe fitting, cylinder three is started, and the piston rod of cylinder three pushes the mounting block to move, so that the mounting block drives the clamping block to move toward the direction close to the clamping block, so that when the pipe fitting is bent, the clamping block continuously presses the pipe fitting in the bending groove, thereby improving the bending efficiency of the pipe fitting.

[0017] Preferably, guide rails are fixed on both sides of the top surface of the workbench, and a movable seat is slidably provided on the two guide rails, and a side plate is fixed on the side of the movable seat close to the rotating shaft, and a movable plate is provided on one side of the side plate, and a clamping block 1 is fixed on the side of the side plate close to the movable plate, and a clamping block 2 is fixed on the side of the movable plate close to the side plate, and a cylinder 4 is fixed on the side of the side plate away from the movable plate, and the piston rod of the cylinder 4 passes through the side plate and is fixed to the side of the movable plate close to the side plate, and the piston rod of the cylinder 4 is slidably connected to the side plate.

[0018] By adopting the above technical solution, when the pipe needs to be bent, the pipe is inserted into the bending groove, and the end of the pipe away from the rotating shaft is located between the clamping block 1 and the clamping block 2. Then, the cylinder 4 is started, so that the piston rod of the cylinder 4 drives the movable plate to move toward the direction close to the side plate, and the movable plate drives the clamping block 2 to move toward the direction close to the clamping block 1, so that the end of the pipe away from the rotating shaft is clamped between the clamping block 1 and the clamping block 2. When the pipe is bent, it is convenient to move the movable seat, so that the movable seat drives the pipe to move forward.

[0019] Preferably, two telescopic rods are fixed between the side plate and the movable plate, and the two telescopic rods are respectively located on both sides of the four-piston rod of the cylinder.

[0020] By adopting the above technical solution, a telescopic rod is set between the side plate and the movable plate. When the piston rod of the cylinder four drives the movable plate to move toward the direction close to the side plate, the movement of the movable plate is made more stable.

[0021] Preferably, a positioning groove is provided on an end surface of the clamping block close to the rotating shaft.

[0022] By adopting the above technical solution, a positioning groove is provided on the clamping block 1, thereby facilitating rapid positioning of the pipe fitting when the pipe fitting is clamped between the clamping block 1 and the clamping block 2.

[0023] In summary, this application includes at least one of the following beneficial technical effects: 1. Insert the pipe into the bending groove, and then start the cylinder 1. The piston rod of the cylinder 1 drives the moving block to move toward the direction close to the rotating shaft, so that the moving block drives the pressing block to move toward the direction close to the rotating shaft, so that the pressing block presses the pipe against the bending ring. Then, the pipe is pressed against the bending ring through the compacting assembly. Finally, start the motor so that the output shaft of the motor drives the rotating shaft to rotate. The rotating shaft drives the bending ring and the connecting plate to rotate at the same time. As a result, the bending ring and the connecting plate rotate and drive the pipe to rotate and bend, reducing the number of workers bending the pipes, thereby improving the bending efficiency of the pipes. 2. When the pipe fitting is inserted into the bending groove, the pipe fitting is also inserted into the plug-in groove, and then the cylinder 1 is started, so that the piston rod of the cylinder 1 pushes the moving block to move toward the direction close to the rotating shaft, and the moving block drives the pressing block to move toward the direction close to the rotating shaft, so that the pressing block presses against the outer circumference of the bending ring and the surface of the pressing block at the same time, thereby increasing the contact area between the pressing block and the pipe fitting, and then the pressing block presses the pipe fitting into the bending groove; 3. When the pipe is inserted into the bending groove and is ready to be bent, start cylinder 2. The piston rod of cylinder 2 drives the slide to move toward the direction close to the rotating shaft, so that the slide drives the clamping block to move toward the direction close to the rotating shaft, so that the clamping block presses the pipe against the outer circumference of the bending ring. When the bending ring and the connecting plate rotate and drive the pipe to rotate for bending, the possibility of the pipe end away from the rotating shaft rotating is reduced, thereby facilitating the bending of the pipe.

A pressing block 34 is fixed to the side of the slider 33 near the rotating shaft 11. A fixed block 35 is fixed to the top surface of the sliding block 31. A screw 36 is threaded through the side of the fixed block 35 and is threadedly connected to the fixed block 35. The end of the screw 36 closest to the rotating shaft 11 is rotatably mounted on the side of the slider 33 away from the rotating shaft 11. A tilted cylinder 1 37 is fixed to the bottom surface of the mounting block 44. The top end of the piston rod of cylinder 1 37 is fixed to the bottom surface of the moving block 3. The piston rod of cylinder 1 37 can push the sliding block 31 to move tilted upward.

[0032] When the pipe needs to be bent, the pipe is inserted into the plug-in groove 17 and the bending groove 14, and the cylinder 1 37 is started. The piston rod of the cylinder 1 37 pushes the sliding block 31 toward the direction close to the pressing block 16, so that the tightening block 34 presses against the side of the pressing block 16, thereby making the tightening block 34 press the bent pipe into the plug-in groove 17.

[0033] Reference Figure 1 and Figure 2 A base 4 is fixed to the side of the workbench 1, and the base 4 is located on one side of the rotating shaft 11.

[0034] Reference Figure 1 A compacting block 5 is fixed to the top surface of the workbench 1, opposite to the pressing block 45. The end surface of the compacting block 5 near the rotating shaft 11 is in contact with the outer circumference of the bending ring 13. A notch 51 for inserting a pipe is provided on the side of the compacting block 5 near the compacting block 45. The notch 51 is connected to the bending groove 14, and the side opposite the compacting block 45 can be in contact with each other.

[0035] When bending a pipe, the pressing block 34 presses the bent pipe into the insertion groove 17, and then the second cylinder 46 is started. The piston rod of the second cylinder 46 pushes the slide 42 toward the direction close to the compacting block 5, so that the compacting block 45 presses the pipe into the slot 51. Then the motor 12 is started, and the third cylinder 47 is also started, so that the output shaft of the motor 12 drives the rotating shaft 11 to rotate, and the rotating shaft 11 drives the bending ring 13 and the mounting seat 21 to rotate. Since the pressing block 34 presses the pipe into the insertion groove 17, the bending ring 13 rotates and drives the pipe to rotate and bend. When the bending ring 13 rotates, the piston rod of the third cylinder 47 pushes the mounting block 44 to move, so that the mounting block 44 drives the compacting block 45 to move, so that when the pipe is bent, the compacting block 45 presses the bent part of the pipe against the compacting block 5, thereby improving the bending efficiency and bending quality of the pipe.

[0036] Reference Figure 1 and Figure 2 Guide rails 6 are fixed to both sides of the top surface of the workbench 1, and movable seats 61 are slidably mounted on the two guide rails 6. A side plate 62 is fixed to the side of the movable seat 61 near the rotating shaft 11. A movable plate 63 is mounted on one side of the side plate 62, and two telescopic rods 68 are fixed between the side plate 62 and the movable plate 63. A clamping block 1 64 is fixed to the side of the side plate 62 near the movable plate 63. A positioning groove 65 is defined on the end surface of the clamping plate 1 near the rotating shaft 11. The positioning grooves 65 extend through the top and bottom surfaces of the clamping block 1 64 and the side of the clamping block 1 64 near the movable plate 63. A clamping block 2 66 is fixed to the side of the movable plate 63 near the side plate 62. A cylinder four 67 is fixed to the side of the side plate 62 away from the movable plate 63, and two telescopic rods 68 are respectively located on both sides of the piston rod of the cylinder four 67. The piston rod of the cylinder four 67 passes through the side plate 62 and is fixed to the side of the movable plate 63 close to the side plate 62. The piston rod of the cylinder four 67 is slidably connected to the side plate 62.

[0037] When bending the pipe fitting, the pipe fitting is passed through the connecting groove 17, the bending groove 14 and the notch 51, and the end of the pipe fitting is inserted into the positioning groove 65 so that the end face of the pipe fitting abuts against the inner side wall of the positioning groove 65. Then, the cylinder four 67 is started, and the piston rod of the cylinder four 67 drives the movable plate 63 to move toward the side plate 62, so that the side plate 62 drives the clamping block 2 66 to move, so that the clamping block 2 66 clamps the pipe fitting in the positioning groove 65. After the pipe fitting is bent, the movable seat 61 is moved toward the direction close to the rotating shaft 11, so that the movable seat 61 drives the pipe fitting to move, thereby facilitating the bending of the next part of the pipe fitting.

[0038] The implementation principle of a luggage tube bending machine in an embodiment of the present application is as follows: when the tube needs to be bent, the initial state of the mounting seat 21 is located on one side of the base 4, and then the tube is passed through the plug-in slot 17, the bending slot 14 and the notch 51, so that the end of the tube away from the rotating shaft 11 is inserted into the positioning slot 65, and then the cylinder four 67 is started, so that the piston rod of the cylinder four 67 drives the movable plate 63 to move toward the direction close to the side plate 62, so that the movable plate 63 drives the clamping block two 66 to move, so that the clamping block two 66 moves toward the direction close to the clamping block one 64, so that the clamping block two 66 clamps the end of the tube in the positioning slot 65. Then start cylinder 1 37 and cylinder 2 46, and the piston rod of cylinder 1 37 pushes the sliding block 31 upward, so that the sliding block 31 drives the clamping block 34 to move toward the direction close to the pressure block 16, and the clamping block 34 is pressed against the side of the pressure block 16, so that the clamping block 34 presses the bent pipe into the plug-in groove 17. At the same time, the piston rod of cylinder 2 46 pushes the base 4 to move toward the direction close to the compacting block 5, so that the clamping block 45 presses the pipe fitting into the groove 51. Then start the motor 12 and cylinder 3 47 at the same time, so that the output shaft of the motor 12 drives the rotating shaft 11 to rotate, and the rotating shaft 11 drives the bending ring 13 and the mounting seat 21 to rotate. Since the bending ring 13 rotates, the clamping block 34 always presses the pipe fitting into the plug-in groove 17, so that the bending ring 13 drives the pipe fitting to rotate and bend when it rotates, reducing the use of manual bending of the pipe fittings, thereby improving the bending efficiency of the pipe fittings. When the bending ring 13 rotates, the piston rod of the cylinder 3 47 pushes the mounting block 44 to move, so that the mounting block 44 drives the pressing block 45 to move, so that when the pipe is bent, the pressing block 45 presses the bending part of the pipe against the compacting block 5, thereby improving the bending efficiency and bending quality of the pipe.

[0039] When one of the pipe fittings is bent, cylinder 1 37 , cylinder 2 46 and cylinder 3 47 are started, so that the piston rod of cylinder 1 37 drives the sliding block 31 to move downward, and the sliding block 31 drives the tightening block 34 to move downward, so that the top surface of the tightening block 34 moves to the bottom of the bending groove 14 , and the piston rod of cylinder 2 46 drives the base 4 to move in the direction away from the rotating shaft 11, so that the pressing block 45 disengages from the compacting block 5 , and the piston rod of cylinder 3 47 drives the mounting block 44 to move into the moving groove 43 , and then moves the moving seat 61 so that the moving seat 61 drives the pipe fitting to move forward, so that the bending part of the pipe fitting disengages from the bending groove 14 , and then starts the motor 12 again, so that the output shaft of the motor 12 drives the rotating shaft 11 to rotate in the opposite direction, and the rotating shaft 11 drives the bending ring 13 and the mounting seat 21 to move, so that the mounting seat 21 moves to one side of the base 4, thereby facilitating the bending of the next part of the pipe fitting.

[0040] The above are all preferred embodiments of the present application, and are not intended to limit the scope of protection of the present application. Therefore, any equivalent changes made based on the structure, shape, and principle of the present application should be included in the scope of protection of the present application.
