DETAILED DESCRIPTION

[0020] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0021] An aluminum pipe bending machine, comprising a pipe bending machine body 1, such as Figure 1 , and also includes a base 2 and a lower conveyor belt 4 and an upper conveyor belt 5 for conveying the pipe 3. The base 2 is located at the front side of the pipe bending machine body 1, and two support frames 6 are provided at the top of the base 2. The two support frames 6 are opposite to each other on the left and right. The lower conveyor belt 4 and the upper conveyor belt 5 are both located between the two support frames 6, and the two support frames 6 are fixedly connected to the lower conveyor belt 4 through a mounting plate 7. The upper conveyor belt 5 is located above the lower conveyor belt 4. The two support frames 6 are provided with a pushing member for driving the upper conveyor belt 5 to move vertically up and down, and the pipe 3 is located between the lower conveyor belt 4 and the upper conveyor belt 5.

[0022] like Figure 1 and Figure 2 and Figure 3 When in use, one end of the first pipe 3 is placed on the front end of the lower conveyor belt 4, and then the upper conveyor belt 5 is pushed downward by the pusher until the upper conveyor belt 5 presses the pipe 3 against the lower conveyor belt 4, and then the pipe 3 is conveyed toward the pipe bending machine body 1 by the upper conveyor belt 5 and the lower conveyor belt 4. When conveyed to the pipe bending machine body 1, the pipe 3 is bent by the pipe bending machine body 1; When the end of the first pipe 3 away from the pipe bender body 1 enters between the upper conveyor belt 5 and the lower conveyor belt 4 as the upper conveyor belt 5 and the lower conveyor belt 4 are conveyed, the second pipe 3 is aligned with and in contact with the first pipe 3, and then the second pipe 3 is inserted between the upper conveyor belt 5 and the lower conveyor belt 4 as the upper conveyor belt 5 and the lower conveyor belt 4 work. Then, as the upper conveyor belt 5 and the lower conveyor belt 4 work, the second pipe 3 and the first pipe 3 will approach the pipe bender body 1. When the first pipe 3 is processed, the first pipe 3 is conveyed out from between the upper conveyor belt 5 and the lower conveyor belt 4 through the work of the upper conveyor belt 5 and the lower conveyor belt 4, and the second pipe 3 is conveyed to the pipe bender body 1 for processing. When the first pipe 3 is conveyed out from between the upper conveyor belt 5 and the lower conveyor belt 4, the processed first pipe 3 can be removed. As the upper conveyor belt 5 and the lower conveyor belt 4 convey the second pipe 3 away from the end of the pipe bender body 1, the third pipe 3 is aligned with and in contact with the second pipe 3. Then, as the upper conveyor belt 5 and the lower conveyor belt 4 work, the third pipe 3 is inserted between the upper conveyor belt 5 and the lower conveyor belt 4, and so on. A batch of pipes 3 with the same diameter are conveyed to the pipe bender body 1 for processing one by one, reducing the waiting gap generated during the use of the pipe bender body 1, thereby improving the bending processing efficiency.

[0023] like Figure 2 and Figure 3 and Figure 4 The lower conveyor belt 4 includes two opposite first baffles 8, and two first rollers 9 are rotatably connected between the two first baffles 8, and the two first rollers 9 are connected by a first conveyor belt 10, one of the first baffles 8 is provided with a first motor 12 for driving one of the first rollers 9 to rotate, and one end of the two mounting plates 7 away from the support frame 6 is respectively connected to the two first baffles 8, and a support plate 13 located in the first conveyor belt 10 is horizontally provided between the two first baffles 8, and the top end of the support plate 13 is in contact with the top end of the first conveyor belt 10; The upper conveyor belt 5 includes two opposite second baffles 14, two second rollers 15 are rotatably connected between the two second baffles 14, and the two second rollers 15 are connected by a second conveyor belt 16. The second conveyor belt 16 corresponds to the first conveyor belt 10 up and down, and one of the second baffles 14 is provided with a second motor 17 for driving one of the second rollers 15 to rotate, and the top ends of the two second baffles 14 are connected by an inverted U-shaped connecting plate 18, and the number of the connecting plates 18 is several, and each connecting plate 18 is spaced apart along the length direction of the second baffle 14, and the top ends of each connecting plate 18 are connected by a movable plate 19, and the pushing members on the two support frames 6 are used to push the movable plate 19 to move vertically, and the pipe 3 is located between the first conveyor belt 10 and the second conveyor belt 16.

[0024] like Figure 2 and Figure 3 and Figure 4, turn on the first motor 12 and the second motor 17 at the same time, the rotating shaft of the first motor 12 will drive one of the first rollers 9 to rotate, and the rotating first roller 9 will drive the other first roller 9 to rotate through the first conveyor belt 10, and the rotating shaft of the second motor 17 will drive one of the second rollers 15 to rotate, and the rotating second roller 15 will drive the other second roller 15 to rotate through the second conveyor belt 16, and the first conveyor belt 10 and the second conveyor belt 16 will transport the pipe 3 between the first conveyor belt 10 and the second conveyor belt 16 to the direction close to the pipe bending machine body 1, the first motor 12 and the second motor 17 are servo motors, and the conveying speed of the first conveyor belt 10 and the second conveyor belt 16 is consistent; Since the top of the support plate 13 contacts the top of the first conveyor belt 10, the first conveyor belt 10 can be supported by the support plate 13, thereby reducing the situation where the pipe 3 squeezes the first conveyor belt 10 and causes the first conveyor belt 10 to bend downward.

[0025] like Figure 2 The two support frames 6 each include a first vertical plate 20 and two second vertical plates 21 arranged on the base 2, the first vertical plate 20 is located between the two second vertical plates 21, the pushing member includes a slide groove 22 vertically opened on one side of the first vertical plate 20 and the two second vertical plates 21, and a slider 23 is vertically slidably connected in the slide groove 22, the three sliders 23 are all fixedly connected to the movable plate 19, the first vertical plate 20 is provided with a first electric cylinder 24 for pushing the slider 23 on the first vertical plate 20 to vertically move, and the mounting plate 7 is arranged on one side of the first vertical plate 20 and the two second vertical plates 21.

[0026] like Figure 2 When it is necessary to drive the upper conveyor belt 5 to move vertically, it is only necessary to open the first electric cylinder 24. The piston rod of the first electric cylinder 24 pushes the slider 23 on the first vertical plate 20 to move vertically. At this time, the upper conveyor belt 5 formed by the movable plate 19, the second baffle plate 14, the second roller 15, the second conveyor belt 16, the connecting plate 18 and the second motor 17 will move vertically following the slider 23 on the first vertical plate 20. When the movable plate 19 moves vertically, the movable plate 19 will drive the slider 23 on the second vertical plate 21 to slide vertically in the slide groove 22. At this time, the cooperation between the slider 23 on the second vertical plate 21 and the slide groove 22 can improve the stability of the upper conveyor belt 5 during vertical movement.

[0027] like Figure 1 and Figure 2 The movable plate 19 is provided with a rotating member for driving the pipe 3 located between the first conveyor belt 10 and the second conveyor belt 16 to rotate. The purpose of this arrangement is to drive the pipe 3 to rotate through the rotating member, so that the pipe bending machine body 1 can bend the pipe 3 multiple times in different directions; After the pipe 3 is bent once by the pipe bender body 1, the pipe 3 is conveyed by the upper conveyor belt 5 and the lower conveyor belt 4 until the next location on the pipe 3 that needs to be bent is conveyed to the pipe bender body 1, and then the pipe 3 is rotated by the rotating member. After rotating to a suitable angle, the pipe 3 is bent for the second time by the pipe bender body 1.

[0028] like Figure 2 and Figure 3 and Figure 4 and Figure 5 The rotating member includes a slideway 25 arranged at the bottom of the moving plate 19 along the width direction of the moving plate 19. The number of the slideways 25 is consistent with the number of the connecting plates 18, and each slideway 25 corresponds to each connecting plate 18. A slide plate 26 is horizontally slidably connected in each slideway 25, and the bottom end of the slide plate 26 is fixedly connected to the top of the connecting plate 18. The moving plate 19 is provided with a driving member for driving each connecting plate 18 to slide horizontally on the moving plate 19 through the cooperation of the slide plate 26 and the slideway 25. The first conveyor belt 10 is provided with a limiting member for limiting the position of the pipe 3 when the pipe 3 rotates. The driving member includes a push plate 27 and a side plate 28 arranged at the bottom end of the movable plate 19. The side plate 28 is located on one side of each connecting plate 18. The push plate 27 is horizontally fixedly connected between two adjacent connecting plates 18, and the push plate 27 corresponds to the side plate 28. The push plate 27 is provided with a second electric cylinder 29, and one end of the piston rod of the second electric cylinder 29 passes through the side plate 28 and is fixedly connected to the push plate 27; The limiting member includes a plurality of limiting plates 30 arranged on the outer side wall of the first conveyor belt 10, and each limiting plate 30 is evenly distributed along the circumference of the first conveyor belt 10, and each limiting plate 30 is provided with an arc-shaped side groove 31 on one side, and the side groove 31 is connected to the side of the limiting plate 30 away from the first conveyor belt 10, and each side groove 31 is provided with a plurality of placement grooves 32 on the arc-shaped groove wall, and each placement groove 32 is evenly distributed along the arc direction of the side groove 31, and a rotating column 33 is rotatably connected between the front and rear side groove walls of each placement groove 32, and the pipe 3 is placed in the side groove 31 of each limiting plate 30 above the first conveyor belt 10 and contacts with the rotating column 33.

[0029] like Figure 2 and Figure 3 and Figure 4 and Figure 5When it is necessary to drive the pipe 3 to rotate, it is only necessary to open the second electric cylinder 29. The piston rod of the second electric cylinder 29 pushes the push plate 27 to drive the connecting plate 18 to move horizontally on the moving plate 19 along the width direction of the moving plate 19. At this time, the connecting plate 18 drives the slide plate 26 to slide in the slideway 25. The two second baffles 14, the two second rollers 15, the second conveyor belt 16 and the second motor 17 move with the connecting plate 18. At this time, the second conveyor belt 16 that contacts the pipe 3 can drive the pipe 3 above the first conveyor belt 10. The limiting plate 30 rotates in the side groove 31, and the rotating column 33 in the groove 32 is placed on the groove wall of the side groove 31, so that the friction resistance between the pipe 3 and the groove wall of the side groove 31 can be reduced, so that the second conveyor belt 16 can drive the pipe 3 to rotate when it moves horizontally. At the same time, because the side groove 31 is arc-shaped, the second conveyor belt 16 conflicts with the pipe 3, so the side groove 31 on the limiting plate 30 can limit the pipe 3 when the pipe 3 rotates, reducing the displacement of the pipe 3 due to the rotation, thereby affecting the pipe bending machine body 1 to process the pipe 3; Because the rotating column 33 is rotatably connected between the front and rear side walls of the placement groove 32, the axis of the rotating column 33 is parallel to the axis of the pipe 3. Therefore, when the first conveyor belt 10 and the second conveyor belt 16 transport the pipe 3, the rotating column 33 will not cause the first conveyor belt 10 and the second conveyor belt 16 to slip when transporting the pipe 3.

[0030] like Figure 3 and Figure 4 A limiting member for limiting the deviation of the second conveyor belt 16 on the second roller 15 is provided between the two second baffles 14, and the limiting member includes a plurality of limiting rollers 34 rotatably connected between the two second baffles 14, and each limiting roller 34 is spaced apart along the length direction of the second baffle 14, and the inner side wall of the second conveyor belt 16 is provided with a limiting groove 35 connected head to tail, and the number of the limiting grooves 35 is several, and each limiting groove 35 is spaced apart on the second conveyor belt 16 along the length direction of the second roller 15, and each limiting roller 34 is coaxially fixedly connected with a plurality of retaining rings 36, and each retaining ring 36 corresponds one by one to each limiting groove 35, and the bottom end of the retaining ring 36 is located in the limiting groove 35.

[0031] like Figure 3 and Figure 4 When the second conveyor belt 16 moves horizontally and drives the pipe 3 to rotate, since the retaining ring 36 on the limiting roller 34 is located in the limiting groove 35, the second conveyor belt 16 can be restricted by the cooperation between the limiting groove 35 and the retaining ring 36 on the limiting roller 34, so that it will not deviate when the second conveyor belt 16 moves horizontally and drives the pipe 3 to rotate.

[0032] like Figure 2 and Figure 6, an inverted U-shaped mounting bracket 37 is provided at the bottom end of one of the second baffles 14, and the bottom end of the mounting bracket 37 is flush with the outer bottom end of the second conveyor belt 16, a T-shaped fixing plate 38 is provided on the first baffle 8 located below the mounting bracket 37, the bottom end of the pipe 3 placed on the rotating column 33 in the side groove 31 is flush with the top end of the fixing plate 38, and a distance sensor 39 for detecting the distance between the fixing plate 38 and the mounting bracket 37 is provided on the inner side wall; When the second conveyor belt 16 contacts the top of the pipe 3, the distance sensor 39 obtains the distance between the mounting frame 37 and the fixed plate 38, and determines the diameter of the pipe 3 according to the distance. The circumference of the pipe 3 is determined according to the diameter of the pipe 3 according to the formula c=πd, and the moving distance of the connecting plate 18 on the movable plate 19 driven by the piston rod of the second electric cylinder 29 to push the push plate 27 is determined according to the circumference of the pipe 3. The rotation angle of the pipe 3 can be determined according to the moving distance. For example, if the distance that the piston rod of the second electric cylinder 29 pushes the connecting plate 18 to move is c, then the pipe 3 rotates 360°. If the distance that the piston rod of the second electric cylinder 29 pushes the connecting plate 18 to move is c / 2, then the pipe 3 rotates 180°. It is simple and convenient to use.

[0033] The use of this device is as follows: The first step is to place one end of the first pipe 3 in the side groove 31 of the limiting plate 30 located at the front end of the first conveyor belt 10 during use.

[0034] In the second step, the first electric cylinder 24 is turned on. The piston rod of the first electric cylinder 24 pushes the slider 23 on the first vertical plate 20 to move vertically downward. At this time, the upper conveyor belt 5 formed by the movable plate 19, the baffle plate, the second roller 15, the second conveyor belt 16, the connecting plate 18 and the second motor 17 will follow the slider 23 on the first vertical plate 20 and move downward until the second conveyor belt 16 presses the pipe 3 against the first conveyor belt 10.

[0035] The third step is to turn on the first motor 12 and the second motor 17. The rotating shaft of the first motor 12 will drive one of the first rollers 9 to rotate. At this time, the rotating first roller 9 will drive the other first roller 9 to rotate through the first conveyor belt 10. The rotating shaft of the second motor 17 will drive one of the second rollers 15 to rotate. At this time, the rotating second roller 15 will drive the other second roller 15 to rotate through the second conveyor belt 16. At this time, the first conveyor belt 10 and the second conveyor belt 16 will transport the pipe 3 between the first conveyor belt 10 and the second conveyor belt 16 toward the direction close to the pipe bending machine body 1.

[0036] In the fourth step, as the first conveyor belt 10 and the second conveyor belt 16 transport the tube 3 toward the direction approaching the tube bender body 1, when the end of the first tube 3 away from the tube bender body 1 enters between the first conveyor belt 10 and the second conveyor belt 16, the second tube 3 is aligned and contacted with the first tube 3, and then as the first conveyor belt 10 and the second conveyor belt 16 work, the second tube 3 is inserted between the first conveyor belt 10 and the second conveyor belt 16. At this time, the second tube 3 located between the first conveyor belt 10 and the second conveyor belt 16 will be located in the side groove 31 of the limit plate 30, and then as the first conveyor belt 10 and the second conveyor belt 16 work, the second tube 3 and the first tube 3 will approach the tube bender body 1.

[0037] In the fifth step, the first pipe 3 is transported to the pipe bending machine body 1 , and the first pipe 3 is bent by the pipe bending machine body 1 .

[0038] Through the fifth step, when the first tube 3 is processed, the first tube 3 is conveyed out from between the first conveyor belt 10 and the second conveyor belt 16 through the operation of the first conveyor belt 10 and the second conveyor belt 16, and the second tube 3 is conveyed to the tube bending machine body 1 for processing. When the first tube 3 is conveyed out from between the first conveyor belt 10 and the second conveyor belt 16, the processed first tube 3 is taken out; When the second tube 3 is transported to the tube bender body 1 for processing, the end of the second tube 3 away from the tube bender body 1 will enter between the first conveyor belt 10 and the second conveyor belt 16. At this time, the third tube 3 is aligned and contacted with the second tube 3. Then, as the first conveyor belt 10 and the second conveyor belt 16 work, the third tube 3 is inserted between the first conveyor belt 10 and the second conveyor belt 16. At this time, the third tube 3 located between the first conveyor belt 10 and the second conveyor belt 16 will be located in the side groove 31 of the limit plate 30, and so on. A batch of tubes 3 with the same diameter are transported to the tube bender body 1 for processing one by one, reducing the waiting gap generated during the use of the tube bender body 1, thereby improving the bending processing efficiency.

[0039] In the fifth step, when the first tube 3 needs to be bent multiple times in different directions, the first tube 3 is bent once by the tube bender body 1, and then the first tube 3 is transported by the first conveyor belt 10 and the second conveyor belt 16 until the next place on the first tube 3 that needs to be bent is transported to the tube bender body 1, and then the piston rod of the second electric cylinder 29 pushes the push plate 27 to drive the connecting plate 18 to move horizontally on the movable plate 19 along the width direction of the movable plate 19, so that the second conveyor belt 16 moves horizontally. At this time, the second conveyor belt 16 that contacts the tube 3 can drive the tube 3 to rotate in the side grooves 31 of each limit plate 30 above the first conveyor belt 10. After the tube 3 rotates to a suitable angle, the tube 3 can be bent for the second time by the tube bender body 1, and so on, until the first tube 3 completes the bending process; When the first tube 3 is completely transported out from between the first conveyor belt 10 and the second conveyor belt 16, the second conveyor belt 16 can be horizontally moved back to its original position by the second electric cylinder 29. When the second conveyor belt 16 moves horizontally to drive the first tube 3 to rotate, the second conveyor belt 16 will also drive the second tube 3 to rotate.
