Description

Technical Field

[0001] This utility model relates to the field of pipe bending equipment technology, and in particular to a high-efficiency combined pipe bending machine. Background Technology

[0002] In the field of metal pipe processing, such as the manufacturing of automotive exhaust systems and air conditioning pipes, the conventional process is as follows: first, long pipes are cut to a fixed length; then, the ends of the pipe sections are treated, such as by flaring or shrinking; finally, the treated pipe sections are sent to a pipe bending machine for bending and shaping. Currently, the industry commonly uses automated equipment for this type of production, such as using robotic arms to transfer pipe sections between different workstations.

[0003] However, existing mainstream processes have certain efficiency drawbacks. Specifically, the traditional processing method is as follows: a robotic arm picks up a pipe segment cut to a fixed length, moves it, and places it on a dedicated fixed fixture. The fixture firmly clamps the pipe segment, and then the end-processing device is activated to process the pipe end. After the end processing is completed, the robotic arm needs to pick up the pipe segment again, remove it from the fixed fixture, and then transfer it to the subsequent bending and forming station for placement and bending.

[0004] However, this model results in numerous unnecessary robot arm placement and waiting actions throughout the processing cycle. While the pipe segment is clamped at the port processing station, the robot arm remains idle or waiting, leading to wasted equipment utilization. Simultaneously, frequent gripping and placement increase the overall cycle time, limiting the improvement of the entire production line's takt time and becoming a key issue restricting further increases in production efficiency. Utility Model Content

[0005] This invention overcomes the shortcomings of the prior art and provides a high-efficiency combined pipe bending machine with a compact structure, small footprint, and high working efficiency.

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

[0007] A high-efficiency combined pipe bending machine includes a frame, on which a cutting station and a bending forming station are provided.

[0008] The frame is provided with a gantry frame, and the gantry frame is provided with a gripping device that can move along it; the gripping device includes a clamping mechanism and a lifting mechanism for driving the clamping mechanism to rise and fall; the gantry frame is also provided with a first linear drive mechanism for driving the gripping device to reciprocate between the cutting station and the bending forming station.

[0009] The gantry is also equipped with a pipe end processing device, which is located on the moving path of the clamping mechanism between the cutting station and the bending and forming station. The cut pipe segment is clamped by the clamping mechanism, and its pipe end is processed by the pipe end processing device during the process of being transferred to the bending and forming station.

[0010] Furthermore, the gantry frame is provided with at least one guide column, and a linear rolling bearing that cooperates with the guide column is correspondingly installed on the mounting base plate of the gripping device.

[0011] Furthermore, the pipe end processing device includes a processing head and a second linear drive mechanism that drives the processing head toward or away from the end of the clamped pipe segment.

[0012] Furthermore, the pipe end processing device is a chamfering device, a flaring device, a narrowing device, or a flanging device.

[0013] Furthermore, the cutting station and the bending and forming station are arranged sequentially on the same side of the frame along the moving direction of the gripping device.

[0014] Furthermore, the first linear drive mechanism and / or the second linear drive mechanism are servo motor driven lead screw and nut mechanisms.

[0015] Furthermore, the clamping mechanism is a pneumatic clamp, a hydraulic clamp, or an electric clamp.

[0016] Furthermore, the driving direction of the second linear drive mechanism is perpendicular to the driving direction of the first linear drive mechanism.

[0017] Furthermore, there are two guide posts, which are arranged in parallel and symmetrically on both sides of the movement path of the gripping device.

[0018] Compared with the prior art, the beneficial effects of this utility model are:

[0019] This utility model has a compact structure. By arranging the cutting station, bending and forming station, and pipe end processing device under the same gantry frame, it combines multiple functional modules. It occupies little space, and the cutting station and bending and forming station are arranged in a straight line on the same side of the frame, which helps to optimize the layout. It is highly efficient and improves production efficiency. By integrating the pipe end processing process into the movement path of the pipe segment from cutting to forming and bending, it eliminates the intermediate handling, repositioning, and waiting time required in traditional processes, shortens the production cycle, and realizes efficient and continuous production.

[0029] The preferred embodiments of the present invention will be described below with reference to the accompanying drawings. It should be understood that the preferred embodiments described herein are for illustration and explanation only and are not intended to limit the present invention.

[0030] like Figures 1 to 4 As shown, this utility model discloses a high-efficiency combined pipe bending machine, including a frame 1 and a gantry frame 2 fixedly mounted on the frame 1. The frame 1 has two workstations: a cutting station A for cutting long pipes to a fixed length and a bending and forming station B for bending straight pipe sections into the desired shape. In this embodiment, the cutting station A and the bending and forming station B are arranged sequentially on the same side of the frame 1 along the same straight line, resulting in a compact overall structure and saving layout space.

[0031] A gantry frame 2 is positioned across the space between cutting station A and bending station B. A first linear drive mechanism 5 is mounted on the gantry frame 2. In this embodiment, the first linear drive mechanism 5 is a servo motor-driven lead screw and nut mechanism, providing high-precision positioning. The first linear drive mechanism 5 drives a gripping device to reciprocate linearly along the gantry frame 2, enabling it to move precisely between cutting station A and bending station B.

[0032] In this embodiment, the gripping device is an important component for realizing the automatic transfer of workpieces. The gripping device includes a mounting base plate, a lifting mechanism 4 that drives the entire gripping device to move in the vertical direction, and a clamping mechanism 3 installed at the moving end of the lifting mechanism 4. The clamping mechanism 3 can be a pneumatic clamp, a hydraulic clamp, or an electric clamp, used to reliably clamp the pipe fittings.

[0033] In addition, to ensure the stability and accuracy of the gripping device during lifting and horizontal movement and to prevent swaying, two guide columns 6 are symmetrically arranged on the gantry 2. The two guide columns 6 are arranged symmetrically on both sides of the movement path of the gripping device. Correspondingly, linear rolling bearings 7 that cooperate with the two guide columns 6 are installed on the mounting base plate of the gripping device. This symmetrical guide layout helps to enhance the stability of the movement.

[0034] The main feature of this design is that a pipe end processing device is installed on the gantry frame 2, along the moving path between the cutting station A and the bending and forming station B. This pipe end processing device includes a second linear drive mechanism 9 and a processing head 8 driven by it. The driving direction of the second linear drive mechanism 9 is perpendicular to the driving direction of the first linear drive mechanism 5. The second linear drive mechanism 9 drives the processing head 8 to move towards the pipe segment on the gripping device to process the end of the pipe segment. In this embodiment, the second linear drive mechanism 9 is a servo motor-driven lead screw and nut mechanism.

[0035] The processing head 8 can be configured as one of the following devices according to actual process requirements: chamfering device, flaring device, necking device, or flanging device.

[0036] The workflow of this utility model is as follows: At the cutting station A, the long pipe is cut into the required pipe segments at a fixed length; the gripping device moves to the cutting station A, descends via the lifting mechanism 4, and is held by the clamping mechanism 3 after cutting; the gripping device rises, and is then driven by the first linear drive mechanism 5 to carry the pipe segments to the bending and forming station B; when the pipe segment is moved to the position of the pipe end processing device, the gripping device can pause briefly, and at the same time, the second linear drive mechanism 9 drives the processing head 8 to move forward to perform predetermined processing on the end of the pipe segment that is passing by; after the pipe end processing is completed, the processing head 8 retracts, and the gripping device continues to transport the pipe segment with the completed end processing to the bending and forming station B; at the bending and forming station B, the gripping device places the pipe segment into the bending mold, and the bending machine completes the bending and forming operation.

[0037] This utility model has a compact structure. By arranging the cutting station A, bending and forming station B, and pipe end processing device under the same gantry frame 2, it achieves the integration of multiple functional modules. It occupies little space, and the cutting station A and bending and forming station B are arranged in a straight line on the same side of the frame, which helps to optimize the layout. It is highly efficient and improves production efficiency. By integrating the pipe end processing process into the path of pipe segment from cutting to forming and bending, it eliminates the intermediate handling, repositioning, and waiting time required in traditional processes, shortens the production cycle, and achieves efficient and continuous production.

[0038] Finally, it should be noted that the above are merely preferred embodiments of the present utility model and are not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. However, any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
