Description

Technical Field

[0001] This invention relates to the field of metal pipe processing technology, specifically to a stainless steel pipe multi-angle bending and forming processing device. Background Technology

[0002] Stainless steel pipes are very common in daily life, such as some metal supports and pipes. Some metal hangers use relatively more stainless steel pipes. The pipes of metal hangers have a certain degree of curvature. When splicing and welding are used in the processing, they are prone to rusting when exposed to moisture. Furthermore, spliced ​​and welded metal supports are prone to breakage at the weld seams when under stress. Therefore, bending is now used to process metal pipes.

[0003] Chinese invention patent CN115971298A discloses a bending device for metal pipe processing, relating to the field of metal pipe processing technology. It includes a chassis and a bending assembly. A bending motor is located in the center of the chassis, and a transmission assembly is located to the right of the bending motor. The bending assembly is positioned on both sides of the transmission assembly. The bending assembly includes a base, a slide rail, a slide groove, a lead screw, an adjusting motor, a column, a slider, a solid rod, a hollow rod, a conveying pipe, a feed pipe, a discharge pipe, a fan, a support column, and ball bearings. The transmission assembly has a base on both sides, with a slide rail on its upper surface. Slide grooves are symmetrically formed on both sides of the slide rail, and a lead screw is rotatably connected within the slide rail. An adjusting motor is fixedly connected to one end of the lead screw, and a column is threadedly connected to the middle of the lead screw. Slide blocks are symmetrically fixedly connected to both sides of the column. This invention allows for bending of metal pipes from the inside, while simultaneously filling the inside with quartz sand to prevent wrinkles on the inner wall.

[0004] In the above structure, quartz sand is injected into the pipe to fill the metal pipe with filler. During bending, the quartz sand can support the inside of the pipe, thus avoiding creases on the inside and outside of the pipe during bending. However, after bending, the quartz sand is prone to sinking into the inner wall of the pipe and may remain inside. Therefore, completely removing the quartz sand from the pipe requires certain procedures, which is cumbersome. Therefore, there is a need for a pipe bending device that can provide filler pipes, prevent creases from forming during bending, and facilitate the discharge of filler from the pipe. Summary of the Invention

[0010] The housing has two placement slots, each holding one of the bending rods. Each placement slot has three guide slots on opposite sides. A pusher housing is located inside each placement slot, positioned opposite to the pusher housing of the other placement slot. Each bending rod has at least three sliding pieces at its lower section, with each sliding piece's sides embedded in a corresponding guide slot. Each sliding piece slides back and forth along the corresponding guide slot in one direction. The surface of each bending rod is connected to the pusher housing, and the pusher housing pushes a top rod, causing each bending rod to reciprocate in one direction.

[0011] The two outlet holes of the upright plate are respectively matched with the bead string and the top plate; the two outlet holes of the upright plate are close to the side of the second clamping plate with a bayonet; the back of the upright plate is provided with a first storage box and a second storage box.

[0029] The embodiments of the present invention will be described below with reference to the accompanying drawings and related examples. The embodiments of the present invention are not limited to the following examples, and the present invention relates to the relevant necessary components in this technical field, which should be regarded as well-known technology in this technical field and can be known and mastered by those skilled in this technical field.

[0030] like Figures 1 to 9 As shown, a stainless steel pipe multi-angle bending forming processing device includes: a base 1, a first clamping plate 2, a second clamping plate 21, a bending unit 3, a vertical plate 4, a bottom plate 5, a bead string 6, and an ejector plate 7. The base 1 is provided with a bottom plate 5, and the first clamping plate 2 and the second clamping plate 21 are respectively provided above the bottom plate 5. The first clamping plate 2 moves horizontally along the bottom plate 5 towards the second clamping plate 21, and the second clamping plate 21 is fixed to the bottom plate 5. The bending unit 3 is provided in front of the base 1, and the vertical plate 4 is provided at the front end of the base 1. The front of the vertical plate 4 is connected to the rear of the bottom plate 5, and the front of the vertical plate 4 is provided with... There are two outlet holes, which are respectively connected to the first end of the bead string 6 and the top plate 7; the bottom plate 5 has a slot at its center and off the second clamping plate 21, and a lifting plate 11 is provided at the slot, which moves up and down along the slot of the bottom plate 5; the bead string 6 is composed of several spheres, and a metal rod connects the several spheres of the bead string 6; the top plate 7 is composed of several plates spliced ​​together; at least two vertically arranged bending rods 31 are installed in the bending unit 3, and the two bending rods 31 extend from the inside to the top of the bending unit 3.

[0031] This invention places a metal pipe between a first clamping plate 2 and a second clamping plate 21. The first clamping plate 2 clamps the metal pipe towards the second clamping plate 21, thus fixing and limiting the metal pipe. One end of the metal pipe is positioned on the front of the upright plate 4. At this time, a string of beads 6 is introduced into the metal pipe, filling it with material. The string of beads 6 extends to the other end of the metal pipe. Then, the ejector plate 7 bends the metal pipe towards the bending unit 3, which has two bending rods 31 for bending the metal pipe.

[0032] The present invention can fill the inside of a metal pipe with beads 6, which are required to resist bending deformation during the bending process, in order to eliminate excessive deformation at the bend.

[0033] With the above structure, it should be further explained that the bead string 6 of the present invention can be replaced with a matching bead string 6 of different sizes according to the inner diameter of the pipe.

[0034] Each metal rod of the bead string 6 has blocks at both ends that are larger than the cross-sectional diameter of the metal rod. Each sphere of the bead string 6 has two inlay slots. Each inlay slot is strip-shaped and its diameter is larger than the block. Each inlay slot has a limiting curved surface at its opening. The end of each metal rod with the block is inlaid in an inlay slot and is limited by the limiting curved surface at the opening of the inlay slot, thereby preventing the metal rod from falling off the sphere.

[0035] In the above structure, the spheres of the bead string 6 can be bent together, thus making it easier to store.

[0036] The ejector plate 7 is made of several pieces and is used to push the metal pipes into the bending unit 3.

[0037] like Figure 3 As shown, a lifting motor 12 is installed inside the base 1, and a lifting rod is used to connect the lifting motor 12 to the bottom of the lifting plate 11 above it; a control unit 9 is installed inside the base 1, and the control unit 9 is electrically connected to the lifting motor 12 by means of conduit; the control unit 9 extends to the outside of the base 1 by means of conduit.

[0038] With the above structure, it should be further explained that when facing metal pipes with large cross-sections, the lifting motor 12 drags the lifting plate 11 down to make room for the first clamping plate 2, the second clamping plate 21 and the base 1. This allows the jaws of the first clamping plate 2 and the second clamping plate 21 to reach the top of the metal pipe, thereby achieving clamping and limiting of pipes with different diameters.

[0039] In the above structure, the control unit 9 is a circuit board, which is connected to an external power source, servo motor, or computer.

[0040] like Figure 3 As shown, the first clamping plate 2 has an inwardly recessed slot on the side opposite to the second clamping plate 21; a sliding groove is provided at the bottom of the first clamping plate 2 and at both ends; a push rod 52 is connected to the side of the first clamping plate 2 away from the second clamping plate 21, the push rod 52 is located inside the push motor 51, and the push motor 51 is located on the base plate 5; guide protrusions 53 are provided on the front and rear sides of the top of the base plate 5, and each guide protrusion 53 is located in the sliding groove of the first clamping plate 2.

[0041] With the above structure, it should be further explained that the jaws of the first clamping plate 2 and the second clamping plate 21 are used to engage the metal pipe to prevent the metal pipe from falling off during the bending process.

[0042] In the above structure, the drive motor 51 is electrically connected to the control unit 9 via a conduit.

[0043] The drive motor 51 of the present invention is a gear motor. The side of the drive rod 52 connected to the drive motor 51 is provided with teeth. The teeth of the drive rod 52 are meshed with the gear of the drive motor 51. The drive rod 52 moves in one direction by meshing with the drive motor 51.

[0044] like Figure 1 , Figure 2 and Figure 4As shown, the bending unit 3 includes: two bending rods 31, a pusher housing 32, a housing 33, and guide grooves 34. The section of the two bending rods 31 extending outside the housing 33 is the upper section, and the section of the two bending rods 31 located inside the housing 33 is the lower section. The housing 33 has two placement slots, and each placement slot holds one bending rod 31. Each placement slot has three guide grooves 34 arranged laterally on opposite sides. Each placement slot has a pusher housing 32 located inside it, and is arranged opposite to the pusher housing 32 of the other placement slot. The lower section of each bending rod 31 has at least three sliding pieces 311, and the two sides of each sliding piece 311 are respectively embedded in the corresponding guide grooves 34. Each sliding piece 311 slides back and forth in one direction along the corresponding guide groove 34. The surface of each bending rod 31 is connected to the pusher housing 32, and the pusher housing 32 pushes the top rod, causing each bending rod 31 to move back and forth in one direction.

[0045] With the above structure, it should be further explained that the dimensions of the box 33 are not the same (length, width, and height). Therefore, the length of the box 33 can be increased, and the distance between the two placement slots can also be widened. Thus, the gap between the two bending rods 31 can be adjusted according to the diameter of the metal pipe to avoid the gap between the two bending rods 31 being too narrow. When facing a metal pipe with a large diameter, if the two bending rods 31 are too narrow, it will easily cause compression of the pipe.

[0046] The bending unit 3 of the present invention bends the metal pipe by means of two bending rods 31. The metal pipe is led out from the front end of the first clamping plate 2 and the second clamping plate 21 until it is led out between the two bending rods 31. The two bending rods 31 are staggered and are pushed relative to each other by the pushing machine box 32. Therefore, when the metal pipe is placed between the two bending rods 31, the two bending rods 31 push each other inward until the metal pipe between them is bent.

[0047] In the above structure, the metal pipe is pressurized by two bending rods 31 to bend the pipe. The beaded string 6 inside the pipe acts as a filler and supports the inside of the pipe during the extrusion process, so as to minimize the excessive deformation of the metal pipe caused by bending.

[0048] The pusher housing 32 of the present invention is an air pump motor. Each air pump pushes each bending rod 31 in one direction to achieve the push of each bending rod 31. The pusher housing 32 is electrically connected to the control unit 9 through a conduit.

[0049] like Figure 1 As shown, the two outlet holes of the upright plate 4 are respectively matched with the bead string 6 and the top plate 7; the two outlet holes of the upright plate 4 are close to the side of the second clamping plate 21 with a bayonet; the back of the upright plate 4 is provided with a first storage box 8 and a second storage box 81.

[0050] With the above structure, it should be further explained that the upright plate 4 is used to support the metal pipe and to limit one end of the bead string 6 and the ejector plate 7, so as to prevent the bead string 6 and the ejector plate 7 from sliding out to the outside and causing refilling.

[0051] A shaft 821 is horizontally arranged inside the first storage box 8. The other end of the shaft 821 extends to the outside of the first storage box 8 and is connected to the rotating motor 82. The shaft 821 is connected to the end of the bead string 6. Several spheres of the bead string 6 are arranged in a straight line and the bead string 6 surrounds the shaft 821.

[0052] A guide plate 822 with a rolled shape is provided on the outside of the shaft 821. The guide plate 822 houses the string of beads 6. When the rotating motor 82 drives the shaft 821 to push the string of beads 6 outward, the string of beads 6 is pushed out along the rolled direction of the guide plate 822. When stored, it is also stored along the rolled direction of the guide plate 822.

[0053] This design prevents the beads from getting tangled when they are rolled up, and also prevents them from hanging down when rolled up, which would result in insufficient storage and make it difficult to pull them out later by rotating the motor 82 to drive the shaft 821.

[0054] With the above structure, it should be further explained that the rotating motor 82 is electrically connected to the control unit 9 via a conduit.

[0055] The rotating motor 82 rotates the winding bead string 6. When the bead string 6 needs to extend into the metal pipe, the rotating motor 82 rotates in the opposite direction to the winding direction.

[0056] After the metal pipe is processed, the bead string 6 is wound up and stored in the first storage box 8 by rotating the motor 82.

[0057] like Figure 5 As shown, a second storage box 81 is provided below the upright plate 4. The second storage box 81 has an opening at the top. The other side of the second storage box 81 is fixed to the base 1. A swing motor 811 is provided inside the second storage box 81. The swing motor 811 is connected to a swing rod 812. The swing rod 812 is placed at a right angle to the swing motor 811. The swing rod 812 reciprocates through the swing motor 811. The end of the swing rod 812 is connected to one end of the top plate 7 and is connected by a bearing.

[0058] With the above structure, it should be further explained that the swing rod 812 reciprocates in one direction through the swing motor 811, and the rotation angle is equal to or less than 200°. Under normal conditions, the swing rod 812 is placed to the right. After the swing motor 811 is started, the swing rod 812 swings to the outward side, thereby pushing the ejector plate 7 connected to the swing rod 812 in the swing direction, so that several ejector plates 7 are successively ejected from the outlet hole.

[0059] like Figure 5 or Figure 8 As shown, there are several ejector plates 7, which are connected by shafts. Each ejector plate 7 is a long strip. The ejector plate 7 connected to the swing rod 812 moves in one direction through the swing motor 811 and the swing rod 812. The other ejector plates 7 move out of the outlet hole of the vertical plate 4 in sequence. The ejector plate 7 located at the outlet hole of the vertical plate 4 is provided with a protrusion, which is placed on the front of the vertical plate 4.

[0060] After adopting the above structure, it should be further explained that the use of long strips for the top plates 7 can prevent left and right swaying after the top plates 7 are spliced ​​together. The top plates 7 are connected by shafts, so the structure can achieve up and down winding, so that the top plates 7 can be wound into the second storage box 81.

[0061] like Figure 5 As shown, a pad is provided above the second storage box 81. The pad is used to support the top plate 7 that is placed on the vertical plate 4 and the upper half, so as to prevent the top plate 7 of the upper half from falling down due to gravity, thereby reducing the possibility of the top plate 7 not being able to exit smoothly.

[0062] The protrusion on the ejector plate 7, which is located at the outlet hole of the vertical plate 4, is used to prevent the ejector plate 7 from falling off from the outlet.

[0063] A discharge motor is installed below the discharge hole of the upright plate 4. A gear is installed on the discharge motor facing downwards from the discharge hole. Each ejector plate 7 has teeth on the side adjacent to the discharge motor. The teeth of the discharge motor mesh with the teeth of the ejector plate 7. When several ejector plates 7 are pushed outwards by the swing motor 811 and the swing rod 812, the discharge motor also pulls the ejector plates 7 in one direction to prevent them from falling down due to lack of support when they are discharged. When the discharge motor pulls out an ejector plate 7, after the ejector plate 7 reaches the bottom plate 5, it then drives the next ejector plate 7 to mesh with the gear of the discharge motor.

[0064] The above description is only a preferred embodiment of the present invention. It should be noted that those skilled in the art can make several improvements and modifications without departing from the principle of the present invention, and these improvements and modifications should also be considered within the scope of protection of the present invention.
