[0035] The present invention will be described in detail below with reference to specific embodiments.
[0036] In this utility model, unless otherwise explicitly specified and limited, when terms such as "set in," "connected," or "linked" appear, these terms should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a direct connection or a connection through one or more intermediate media. Those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances. The directional terms appearing in this utility model are for the purpose of better describing the characteristics of the features and the relationships between them. It should be understood that when the placement direction of this utility model changes, the direction of the characteristics of the features and the relationships between them also changes accordingly. Therefore, directional terms do not constitute an absolute limitation on the characteristics of the features and the relationships between them in space, but only a relative limitation.
[0037] like Figures 1 to 9 As shown, this utility model provides an aluminum alloy tube bending device, including a base 1. A feeding mechanism 3 and a bending mechanism 2 are provided on the base 1. The feeding mechanism 3 is used to push the aluminum alloy tube to the bending mechanism 2, and the bending mechanism 2 is used to bend the aluminum alloy tube. A heating component 4 is also provided on the base 1. The heating component 4 includes an adjusting rod, a spray gun 43 and an adjusting valve. The adjusting rod is installed on the base 1, the spray gun 43 is installed on the adjusting rod, and the adjusting valve is located in the base 1. The adjusting valve is connected to the spray gun 43 through an air pipe.
[0038] With the above design, when the aluminum alloy tube needs to be bent, the spray gun 43 is automatically ignited to heat the area of the aluminum alloy tube that needs to be bent, so that the local temperature rises, reducing the internal stress during bending and preventing cracks from forming; the regulating valve is used to control the gas supply of the spray gun 43 and connects to the gas pipe or gas tank to supply fuel to the spray gun 43. At the same time, the regulating valve is also equipped with a backfire preventer to prevent flame backflow from causing danger.
[0039] In this embodiment, the adjusting rod includes a vertical rod 40, a horizontal rod 42, a longitudinal tensioning seat 41, and a transverse tensioning seat 45. The longitudinal tensioning seat 41 is fixedly installed on the base 1. The vertical rod 40 can slide and rotate in the longitudinal tensioning seat 41. The transverse tensioning seat 45 is fixedly installed at the top of the vertical rod 40. The horizontal rod 42 can slide and rotate in the transverse tensioning seat 45. A spray gun 43 is installed at one end of the horizontal rod 42.
[0040] In this embodiment, locking knobs 44 are provided on the longitudinal tensioning seat 41, the transverse tensioning seat 45, and the crossbar 42.
[0041] Through the above scheme, the adjusting rod can adjust the spatial position of the spray gun 43 to avoid the spray gun 43 interfering with the bending work of the aluminum alloy tube. When it is necessary to adjust the relative position of the spray gun 43, the user only needs to loosen the locking knob 44. At this time, the vertical rod 40 can rotate or slide in the longitudinal tensioning seat 41. Similarly, the horizontal rod 42 can rotate and slide freely in the transverse tensioning seat 45 until the nozzle of the spray gun 43 is aligned with the area to be bent. Then, turn the locking knob 44 to lock the horizontal rod 42 and the vertical rod 40 to prevent the spray gun 43 from shifting during operation and affecting subsequent work. The locking knob 44 on the horizontal rod 42 can adjust the angle of the spray gun 43 so that the flame sprayed by the spray gun 43 can be aligned with the area to be bent of the aluminum alloy tube.
[0042] In this embodiment, the bending mechanism 2 includes a lateral push assembly 6 and a bending assembly 5. The bending assembly 5 includes a bending seat 50, a bending frame 51 and a clamping drive 7. The lateral push assembly 6 includes a lateral movement drive, a forward push drive and a push plate 64.
[0043] The bending seat 50 is mounted on the base 1, and the bending frame 51 is mounted on the bending seat 50. The bending seat 50 can drive the bending frame 51 to rotate. The bending seat 50 is equipped with a power motor, which is dedicated to providing power for the rotation of the bending seat 50. The clamping drive 7 is mounted on the bending frame 51. The lateral drive is mounted on the base 1. The lateral drive is used to drive the forward drive to move closer to or away from the bending seat 50. The forward drive is used to drive the push plate 64 to move closer to or away from the bending seat 50.
[0044] In this embodiment, the lateral movement drive includes a lateral movement cylinder 60, a lateral movement slide rail, and a lateral movement slide plate 61. The forward push drive includes a forward push cylinder 62 and a connecting plate 63. The lateral movement cylinder 60 and the lateral movement slide rail are both mounted on the base 1. The lateral movement cylinder 60 is used to drive the lateral movement slide plate 61 to slide on the lateral movement slide rail. The forward push cylinder 62 is mounted on the lateral movement slide plate 61. The connecting plate 63 can be mounted on the lateral movement slide plate 61. The forward push cylinder 62 is used to push the connecting plate 63 to slide.
[0045] In this embodiment, the push plate 64 includes a base plate 640, a heat insulation layer 641 and a heat-conducting seat 642. The connecting plate 63 is detachably connected to the base plate 640. The heat-conducting seat 642 is installed in the base plate 640, and the heat insulation layer 641 is provided between the heat-conducting seat 642 and the base plate 640.
[0046] In this embodiment, a detachable bending mold 52 is provided on the bending seat 50, and the clamping drive component 7 includes a clamping cylinder 70, a clamping slide 71 and a clamping mold 72. The clamping cylinder 70 is fixedly installed on the bending frame 51 and is used to drive the clamping slide 71 to slide on the bending frame 51. The clamping slide 71 is provided with a detachable clamping mold 72.
[0047] With the above design, when bending of the aluminum alloy tube is required, the bending frame 51 returns to its original position, the clamping cylinder 70 pushes the clamping slide 71 forward, allowing the clamping mold 72 to clamp the aluminum alloy tube onto the bending mold 52. Then, the transverse cylinder 60 is activated, causing the push plate 64 to approach the aluminum alloy tube. After preparation is complete, the bending seat 50 controls the rotation of the bending frame 51 and the bending mold 52, while the forward push cylinder 62 is activated, driving the push plate 64 to extend at a speed matching the bending mold 52, bending and pressing the aluminum alloy tube (e.g., ...). Figure 4 As shown), after bending is completed, the bending seat 50 drives the bending frame 51 to return to its original position. At the same time, the transverse cylinder 60, the forward pushing cylinder 62, and the clamping cylinder 70 retract synchronously. The clamping mold 72 and the push plate 64 are brought back synchronously to avoid interference (as shown). Figure 3 (As shown).
[0048] When bending is required, the spray gun 43 heats the area of the aluminum alloy tube to be bent, and the heat-conducting seat 642 can transfer the temperature to the aluminum alloy tube more evenly, making the aluminum alloy tube heated more evenly; the heat insulation layer 641 between the heat-conducting seat 642 and the base plate 640 can block the heat transfer to the base plate 640, preventing unnecessary waste.
[0049] In this embodiment, the feeding mechanism 3 includes a feeding drive 30, a feeding slide 31, a rotary drive 32, and a clamping seat 33. The feeding drive 30 is mounted on the base 1 and is used to drive the feeding slide 31 to slide on the base 1. The rotary drive 32 is mounted on the feeding slide 31, and the clamping seat 33 is mounted on the rotary drive 32 and is used to drive the clamping seat 33 to rotate.
[0050] Since the feeding mechanism 3 is existing technology and is not an improvement of this embodiment, it is not described in detail in this embodiment.
[0051] The aluminum alloy tube bending equipment provided by this utility model, compared with the prior art, can use the spray gun 43 to spray flames to heat the area of the aluminum alloy tube to be processed when bending operations are required, thereby improving the elongation effect of the aluminum alloy tube and reducing phenomena such as orange peel, wrinkling or cracking that occur during the bending process.
[0052] Where there is no conflict, the above embodiments and features can be combined with each other.
[0053] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit the scope of protection of this utility model. Although this utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solutions of this utility model without departing from the essence and scope of the technical solutions of this utility model.
