Description

Technical Field

[0001] This utility model belongs to the field of pipe bending equipment technology, and in particular relates to a continuous pipe bending device for processing automotive metal pipes. Background Technology

[0002] Automotive metal pipes are metal pipes used in automobile manufacturing. They are mainly used to transport fluids such as fuel, brake fluid, and refrigerant, or as structural support components. To adapt to the complex space inside a car, they are often bent during production using a pipe bending machine to achieve compact installation.

[0003] Currently, when bending metal pipes, the bent portion is suspended externally, while the unbent portion continues the bending process. This results in uneven stress distribution on the pipe, especially near the bending point, creating stress concentration areas and potentially causing material cracking or plastic deformation.

[0004] To address the aforementioned problems, this application proposes a continuous bending device for processing automotive metal tubes. Utility Model Content

[0005] The purpose of this invention is to provide a continuous bending device for processing automotive metal tubes, which solves the problems mentioned in the background art.

[0006] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution:

[0007] This utility model is a continuous bending device for processing automotive metal tubes, including a bending machine and a bending section in front of it.

[0008] The pipe bending machine is provided with a metal pipe support group in front, which includes a ring sleeve located on the left front of the bending part and sleeved on the outside of the metal pipe. The pipe bending machine is provided with a base in front, and a connecting rod support ring sleeve is rotatably installed on it.

[0009] A support plate is fixedly installed above the base, and a first elastic telescopic rod and a second elastic telescopic rod are provided on the left side in front and behind, which apply tension to the connecting rod in sequence.

[0010] Furthermore, the upper end of the connecting rod is rotatably mounted on the bearing seat at the bottom of the ring sleeve, and the bottom of the connecting rod is fixedly connected to a support plate, which is rotatably mounted in the positioning groove between the support plate and the base.

[0011] Furthermore, a forward-extending side plate is fixedly connected to the left side of the support plate, and an angled positioning link is formed between the side plate and the support plate.

[0012] Furthermore, a fixing rod coaxial with the bend is fixedly installed above the support plate along the axis.

[0013] Furthermore, a first positioning rod is rotatably installed inside the front end of the side plate, and one side is fixedly connected to a first elastic telescopic rod.

[0014] Furthermore, a second positioning rod is rotatably installed on the upper left side of the support plate, and one side is fixedly connected to the second elastic telescopic rod.

[0015] Furthermore, an outer ring seat is fixedly installed on the outer side of the lower end of the connecting rod, and the interior is divided into upper and lower annular grooves for rotatably installing the annular mechanism at the ends of the first elastic telescopic rod and the second elastic telescopic rod.

[0016] This utility model has the following beneficial effects:

[0017] This invention involves placing a ring sleeve around the outside of the pipe near the bend, so that during bending operations, the support disc moves with the bend of the pipe, achieving real-time support at different positions. This ensures uniform stress on the pipe and avoids stress concentration that could cause cracking.

[0018] This utility model utilizes the bidirectional arrangement of the first and second elastic telescopic rods, which can sequentially drive the connecting rod to reset after the pipe bending operation, thereby moving it to the initial position without manual relocation, and automatically adapting to continuous support operations for continuous pipe bending.

[0019] Of course, any product implementing this utility model does not necessarily need to achieve all of the advantages described above at the same time. Attached Figure Description

[0036] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0037] In the description of this utility model, it should be understood that the terms "opening", "upper", "lower", "thickness", "top", "middle", "length", "inner", "around" and other terms indicating orientation or positional relationship are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the components or elements referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this utility model.

[0038] Please see Figure 1-5 As shown, this utility model is a continuous bending device for processing automotive metal tubes, including a bending machine 110 and a bending section 120 in front of it.

[0039] The pipe bending machine 110 has a metal pipe support group in front, which includes a ring 230 located on the left side in front of the bending section 120 and sleeved on the outside of the metal pipe. The pipe bending machine 110 has a base 210 in front, and a connecting rod 220 is rotatably installed on it to support the ring 230, so that the ring 230 automatically adapts to the orientation during the bending process of the metal pipe, achieving the effect of real-time support.

[0040] A support plate 240 is fixedly installed above the base 210. A first elastic telescopic rod 251 and a second elastic telescopic rod 261, perpendicular to the axis of the connecting rod 220, are installed on the left side in both the front and rear directions. The connecting rod 220 is pulled in sequence. After the metal tube is bent, the first elastic telescopic rod 251 releases the tension first, causing the connecting rod 220 to move to the front of the support plate 240. Then, under the action of the tension of the second elastic telescopic rod 261, the connecting rod 220 changes its direction of movement and moves to the left front of the support plate 240, which is the initial position.

[0041] Preferably, the upper end of the connecting rod 220 is rotatably mounted on the bearing seat 231 at the bottom of the ring sleeve 230, and the bottom of the connecting rod 220 is fixedly connected to the support plate 222. The positioning groove 201 between the support plate 240 and the base 210 is rotatably mounted. Ball bearings 201 are rotatably mounted inside the ring sleeve 230 and at the bottom of the support plate 222 to reduce friction and make the movement of the ring sleeve 230 and the support plate 222 more flexible, thus avoiding jamming.

[0042] Preferably, a forward-extending side plate 242 is fixedly connected to the left side of the support plate 240, and an angle positioning link 220 is formed between the side plate 242 and the support plate 240. The axis of this angle is also the axis of the link 220 in the initial position.

[0043] Preferably, a fixing rod 241 coaxial with the bend section 120 is fixedly installed above the support plate 240 along the axis, which is used to position the installation position of the support plate 240 and the base 210, so that the rotation of the connecting rod 220 is around the axis of the bend section 120.

[0044] Preferably, a first positioning rod 250 is rotatably installed inside the front end of the side plate 242, and one side is fixedly connected to the first elastic telescopic rod 251. When the connecting rod 220 moves to the right side of the support plate 240 during the bending operation, the first elastic telescopic rod 251 generates an oblique pulling force on the connecting rod 220 from right to left front.

[0045] Preferably, a second positioning rod 260 is rotatably mounted on the upper left side of the support plate 240, and one side is fixedly connected to the second elastic telescopic rod 261. When the connecting rod 220 is pulled back to the front of the support plate 240 by the first elastic telescopic rod 251, the pulling force of the second elastic telescopic rod 261 comes into play, applying a right-front to left-rear pulling force to the connecting rod 220 until it moves to the initial position. In addition, the second elastic telescopic rod 261 is a bendable elastic telescopic flexible rod. When the bending angle of the metal tube is too large, the part of the second elastic telescopic rod 261 that passes through the fixed rod 241 will bend, avoiding jamming.

[0046] Preferably, an outer ring seat 221 is fixedly installed on the outer side of the lower end of the connecting rod 220, and the inside is divided into upper and lower annular grooves. The opposite ends of the first elastic telescopic rod 251 and the second elastic telescopic rod 261 are fixedly installed with annular blocks, which are fitted inside the upper and lower annular grooves.

[0047] It is understood that this utility model can provide real-time support to the adjacent bending part of the metal pipe during continuous bending operations, avoiding uneven stress caused by the suspension part, and forming a cycle through self-resetting, which can automatically reset to the vicinity of the part to be bent before bending operations, thus achieving a continuous support effect.

[0048] A specific application of the operation flow of this embodiment is as follows: During pipe bending, the ring 230 located on the left side in front of the bending section 120 is fitted onto the outside of the pipe and supported by the connection between the connecting rod 220 and the support plate 222. Subsequently, when the pipe is bent, the ring 230 is driven to rotate synchronously, while the support plate 222 rotates inside the positioning groove 201, thereby achieving the effect of real-time support for the pipe. Further, after bending and shaping and the clamp is removed, the elasticity of the first elastic telescopic rod 251 is used to apply a pulling force to the connecting rod 220, causing it to move in the opposite direction to the front of the support plate 240. Then, the elasticity of the second elastic telescopic rod 261 is used to pull the connecting rod 220 again to move it back to the initial position, thereby driving the ring 230 to move to the left side in front of the bending section 120 to support the pipe. This arrangement forms a cycle, which is suitable for continuous pipe bending operations.
