Abstract
Description
Technical Field
[0001] This invention belongs to the field of pipe bending manufacturing technology, specifically relating to an integrated pipe bending forming machine. Background Technology
[0002] A pipe bending machine is a mechanical device used to bend metal pipes or tubing. It bends the pipe under hydraulic or mechanical force, through a mold, to achieve the desired angle and shape. Pipe bending machines are mainly used for pipe laying in power construction, railway and highway construction, boilers, bridges, ships, furniture, and decoration.
[0003] The current method of bending metal pipes is not done on the production line. Instead, the bending of metal pipes is completed outside the production line, and the pipes are transported to the production line by material carts. Then, the metal pipes are placed onto the sheet metal shells by manual handling. This manual operation method is not compatible with the automated production of sheet metal shells and restricts the increase of sheet metal shell output.
[0004] To address the existing problems, we propose an integrated pipe bending and forming machine.

Detailed Implementation
[0032] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.
[0033] from Figure 1 , Figure 5 , Figure 6 , Figure 7 and Figure 9 As shown,
[0034] A pipe bending forming integrated machine adopts a PLC control system and includes:
[0035] Base 1, with a first track 11;
[0036] Gantry support 2 is located above base 1;
[0037] The conduit mechanism 3 is located on the base 1. The conduit mechanism 3 includes a conduit conveyor 31, a conduit conveying base 32, a second track 33, and a conduit disc 34. The conduit conveying base 32 can move on the second track 33, and the conduit disc 34 can rotate on the conduit conveying base 32. The conduit disc 34 is provided with a guide wheel 35.
[0038] Specifically, the tube conveyor can be a disc with a groove on its edge. After the tube leaves the tube reel, it is recessed into the groove and conveyed onto the guide disc. Several guide wheels 35 are arranged opposite each other to form a U-shaped channel. After the tube extends out of the tube conveyor and leaves the groove, it enters the U-shaped disc for the tube bending process.
[0039] Specifically, the conduit transfer base 32 moves on the second track 33 using a gear and rack transmission mechanism, a cylinder or hydraulic cylinder drive mechanism, or a screw transmission mechanism.
[0040] The tube winding mechanism 4 includes a tube winding base 41, several stops 42 and a clamp 43, which are disposed on the first track 11. The tube winding base 41 can move on the first track 11. The clamp 43 is driven by a clamp power component to clamp the tube body. The stops 42 are on the tube winding base 41.
[0041] Specifically, the tube-wound base 41 can slide or be fixed on the first track 11. The movement of the tube-wound base 41 on the first track 11 can be achieved by a gear and rack transmission mechanism, a cylinder or hydraulic cylinder drive mechanism, or a screw transmission mechanism.
[0042] Specifically, the clamp 43 includes a first clamp 43 and a second clamp 43, both of which are provided with grooves. The clamp power component drives the first clamp 43 and the second clamp 43 to separate or merge. When the first clamp 43 and the second clamp 43 merge, the tube is clamped in the grooves of the first clamp 43 and the second clamp 43.
[0043] The applicator 5 is equipped with a tube bending robot 50, a film clamping robot 51, a film conveying roller 52, a film pressing component 53, and an adhesive application platform 54 to apply the film to the tube bending mechanism. The applicator 5 can move in the X, Y, and Z axis directions.
[0044] The pipe-cutting mechanism 6 is located on one side of the pipe-winding mechanism 4. The pipe-cutting mechanism 6 includes scissors 61 and a scissor power component 62, which drives the scissors 61 to cut the pipe body. Specifically, there are 4 sets of pipe-winding mechanisms 4, and the pipe-cutting mechanism 6 is located on one side of the outermost pipe-winding mechanism 4.
[0045] like Figure 9 As shown,
[0046] The applicator 5 is provided with an applicator base 5 and a fourth track 56. The gantry support 2 is provided with a third track 21 perpendicular to the first track 11. The third track 21 is the Y-axis. The fourth track 56 is located between the gantry support 2 and the base 1. The applicator base 5 can move on the third track 21. The applicator base 5 is provided with a lifting mechanism 57. The output end of the lifting mechanism 57 is connected to the fourth track 56. The running path of the output end of the lifting mechanism 57 is the Z-axis. The applicator 5 also includes an applicator base 581. The film conveying roller 52 and the film pressing component 53 are both provided on the applicator base 581. The applicator base 581 is also provided with an applicator base 582. The applicator base 582 is provided with a fifth track 59. The robot can move on the fifth track 59. The applicator base 581 is also provided with a sixth track 583. The film robot moves along the sixth track 583.
[0047] Specifically, the application mechanism 5 has multiple sets, and these multiple sets of application mechanisms 5 can move on the fourth track 56, which is the X-axis. The distance between adjacent application mechanisms 5 can be adjusted. The movement of the application mechanism 5 on the fourth track 56 can be achieved using a gear and rack transmission mechanism, a cylinder or hydraulic cylinder drive mechanism, or a screw transmission mechanism.
[0048] Specifically, both the pipe bending robot 50 and the clamping robot 51 can be grippers. The opening and closing of the pipe bending robot 50 and the clamping robot 51 are controlled by cylinders. The pipe bending robot 50 can be mounted on a base with a slide rail that can slide on the fifth track 59. The movement of the pipe bending robot 50 on the fifth track 59 can be achieved using a rack and pinion mechanism, a cylinder or hydraulic cylinder drive mechanism, or a screw drive mechanism. The movement of the clamping robot 51 on the sixth track 583 can also be achieved using a rack and pinion mechanism, a cylinder or hydraulic cylinder drive mechanism, or a screw drive mechanism.
[0049] Specifically, the film transport rollers 52 are mounted on the second application base 581 and include a first roller, a second roller, a third roller, and a fourth roller. The first roller mounts the film roll, and the second, third, and fourth rollers are arranged to ensure the film is transported in an "S" shaped path. The film pressing component 53 is driven by a cylinder. After the film is pre-applied onto the curved tube by the film transport rollers 52, the cylinder drives the film pressing component 53 to descend and press the film firmly onto the curved tube.
[0050] like Figure 2 and Figure 4As shown, the all-in-one machine includes a first cutting surface 6111 and a second cutting surface 6121, both of which are provided with grooves. The first cutting surface 6111 is on one side of the second cutting surface 6121. The scissors 61 include a first state and a second state. In the first state, the tube body is in the groove of the first cutting surface 6111 and the second cutting surface 6121, and the first cutting surface 6111 and the second cutting surface 6121 are on the same horizontal plane. In the second state, the tube body is broken, and the first cutting surface 6111 and the second cutting surface 6121 are not on the same horizontal plane.
[0051] The scissors 61 include a first blade body 611, a second blade body 612, a pin 613, a first component 614, a second component 615, and a connector 616. The first blade body 611 includes a first blade head and a first blade handle. The second blade body 612 includes a second blade head and a second blade handle. A first blade face 6111 is disposed on the first blade head, and a second blade face 6121 is disposed on the second blade head. The first blade body 611 and the second blade body 612 are rotatably connected around the pin 613. The pin 613 is connected to the base 1. The first component 614 is rotatably connected to the first blade handle, and the second component 615 is rotatably connected to the second blade handle. The end of the first component 614 away from the first blade handle is rotatably connected to the connector 616, and the end of the second component 615 away from the second blade handle is rotatably connected to the connector 616. The output end of the scissors power unit 62 is connected to the connector 616.
[0052] Specifically, the scissors 61 include a first cutting surface 6111 and a second cutting surface 6121. The first cutting surface 6111 and the second cutting surface 6121 are respectively connected to a first handle and a second handle. The scissors power unit 62 drives the first handle and the second handle to perform lever motion so that the first cutting surface 6111 and the second cutting surface 6121 can cut the tube.
[0053] Specifically, because pin 613 is connected to base 1, base 1 is fixed, and scissor power component 62 is driven by cylinder, scissor power component 62 pushes connector 616, first pin 613 and second pin 613 push first cutter handle and second cutter handle, thereby the first cutter head and second cutter head are engaged to achieve cutting of the tube.
[0054] Such as 3 and Figure 8 As shown, the integrated machine also includes a tube expansion mechanism, which is located on the base 1. The tube expansion mechanism can move on the first track 11. The tube expansion mechanism includes a seventh track 71, a support body 72, a support body power component 73, and a tube expansion base 74. The tube expansion base 74 can move on the seventh track 71 to align the support body 72 with the tube body. The support body 72 is located on the tube expansion base 74. The support body 72 power component drives the support body 72 to expand the inner diameter of the tube body. The movement of the tube expansion base 74 on the seventh track 71 can be achieved by a gear and rack transmission mechanism, a cylinder or hydraulic cylinder drive mechanism, or a screw transmission mechanism.
[0055] Specifically, the expansion mechanism moving on the first track 11 can employ one of the following: a rack and pinion transmission mechanism, a cylinder or hydraulic cylinder drive mechanism, or a screw drive mechanism. Similarly, the expansion base 74 moving on the seventh track 71 can also employ one of the following: a rack and pinion transmission mechanism, a cylinder or hydraulic cylinder drive mechanism, or a screw drive mechanism. Through position adjustment of the expansion mechanism, when the support body 72 and the tube body are aligned, under the action of the power component of the support body 72, the support body 72 inserts into the tube body, expanding the inner diameter of the tube body.
[0056] Specifically, the support 72 includes a first support, a second support, and a third support, with the outer diameters of the first, second, and third supports increasing sequentially. The support power component 73 drives the first support to insert into the tube to complete the first expansion of the tube's inner diameter. Similarly, under the drive of the support power component 73, the first support retracts, and the second support is inserted into the tube to complete the second expansion of the tube's inner diameter. Then, the same method is used to complete the third expansion of the tube's inner diameter using the third support.
[0057] like Figure 3 and Figure 8 As shown, the integrated machine also includes a zinc removal mechanism, which is mounted on the base. The zinc removal mechanism can move on the first track 11 under the drive of the first power component of the zinc removal mechanism. The zinc removal mechanism includes a zinc removal base, an eighth track, a gear 81, and a gear power component 82. The zinc removal base can move on the eighth track under the drive of the second power component of the zinc removal mechanism. The gear 81 is positioned to clamp the tube body, and the gear power component 82 drives the positioned gear 81 to rotate to rub the surface of the tube body.
[0058] Specifically, the two gears 81 are surrounded by housings, and the housings are also provided with through holes. The tube can pass through the through holes and then be inserted between the two gears 81.
[0059] Specifically, the zinc removal base and the tube expansion base 74 can be combined into one base, and the seventh track 71 and the eighth track can also be combined into one track. The first power component of the zinc removal mechanism and the first power component of the tube expansion mechanism can be the same power component (zinc removal and tube expansion first power component). The second power component of the zinc removal mechanism and the second power component of the tube expansion mechanism can be the same power component (zinc removal and tube expansion second power component). If the tube end needs to be expanded, the tube expansion mechanism is adjusted to a suitable position by the zinc removal and tube expansion first power component to expand the tube. If the tube end needs to be dezincified, the zinc removal mechanism is adjusted to a suitable position by the zinc removal and tube expansion first power component to dezincify the tube.
[0060] Working principle and usage process of this invention:
[0061] The tube is placed on the tube conveyor and guided into the path formed by the guide wheel 35 and the guide plate 34. The size of the adjacent winding mechanism 4 is adjusted according to the size of the bent tube. The guide mechanism 3 is started, and the tube conveying mechanism 3 pulls the tube along the first track 11. Because the guide plate 34 can rotate on the tube conveying base 32, the guide mechanism 3 can bend the tube according to the set path of the stop 42 on the winding mechanism 4. After the tube is bent, the tube cutting mechanism 6 drives the scissors to cut the tube under the action of the scissor power component 62. Then the applicating mechanism 5 moves on the third track 21, and the tube bending robot 50 moves on the fifth track 59 until the tube bending robot 50 is adjusted to the corresponding position above the bent tube. The tube bending robot 50 picks up the bent tube and puts it on the applicating platform 54. The film robot grips the film and slides it on the sixth track 583. With the cooperation of the rotating film conveying roller 52, the film is adjusted to be above the bend. The film pressing component 53 descends under the drive of the cylinder, pressing the film and applying it to the bend.
[0062] If the cut bend needs to be connected to other pipes, a pipe expansion mechanism or a zinc removal mechanism is used for pretreatment. The pretreatment process is as follows:
[0063] When the tube end is pre-treated using the tube expansion mechanism, the tube expansion base moves on the first track 11 under the drive of the first tube expansion power component, and moves on the seventh track 71 under the drive of the second tube expansion power component. When the support body 72 and the tube body are opposite each other, the support body power component 73 drives the first support body to insert into the tube body to complete the first expansion of the inner diameter of the tube body. Similarly, under the drive of the support body power component 73, the first support body retracts and the second support body inserts into the tube body to complete the second expansion of the inner diameter of the tube body. Then, the same method is used to complete the third expansion of the inner diameter of the tube body using the third support body.
[0064] When the zinc removal mechanism is used to pre-treat the end of the pipe, the second power component of the zinc removal mechanism drives the zinc removal base to move, so that the pipe is inserted into the gear 81. The gear 81 clamps the pipe, and the gear power component 82 drives the gear 81 to rotate to rub the surface of the pipe, thus completing the zinc removal.
