Description

Technical Field

[0001] This utility model is a connecting device for multi-process processing of pipe products. Background Technology

[0002] The manufacturing process of pipe products typically involves multiple processing steps, such as cutting radius (R), flattening, plugging, and welding. These steps require high-precision, high-efficiency equipment to ensure product quality and production efficiency. However, traditional pipe fitting processing methods rely on manual labor or independent single-machine operation, resulting in low inter-process conveying efficiency, insufficient positioning accuracy, and unstable production cycle, making it difficult to meet the demands of efficient, continuous, and automated production.

[0003] To address the aforementioned issues, a specialized multi-process processing line is needed that can automatically transport, precisely position, and stably transfer pipe fittings. This would reduce manual intervention, improve production efficiency, ensure processing quality, and meet the demands of large-scale automated production. Utility Model Content

[0008] The telescopic cylinder is fixed at one end to the slide rail and connected to the slide plate at the other end. It is used to drive the slide plate to move back and forth on the slide rail to realize the horizontal transfer of the pipe fitting.

[0009] The first lifting cylinder is fixedly connected to the slide plate via a connecting plate, and its telescopic end is connected to the floating joint of the material support frame.

[0010] The material support frame is connected to the first lifting cylinder via a floating joint and is used to support the pipe fittings to be transferred;

[0011] The slide plate is mounted on the slide rail and slides on the slide rail as the telescopic cylinder extends and retracts, providing load transfer support;

[0012] The slider is positioned between the slide rail and the slide plate to allow the slide plate to slide smoothly on the slide rail and reduce frictional resistance.

[0013] A connecting plate is used to connect the slide plate and the first lifting cylinder to ensure that all components move synchronously.

[0014] Positioning blocks, set on the surface of the material support frame, are used to limit the swinging or rolling of the pipe fittings and ensure the stability of the pipe fittings during the transfer process;

[0023] In one possible implementation, the workbench is divided into two surfaces, left and right, according to the equipment arrangement of the connecting process, and the surfaces are connected by a central steel pipe.

[0024] In one possible implementation, multiple sets of fixing blocks for fixing pipe fittings are provided on the two tables, with two fixing blocks in each set, and the fixing blocks are located at the processing position of each working mechanism.

[0027] In one possible implementation, the transmission component includes:

[0028] The unloading mechanism is used to receive the tubular parts conveyed by the transfer components and guide them into the chain conveyor mechanism;

[0029] The chain conveyor mechanism uses a chain drive to arrange the pipes through equally spaced pipe-blocking devices and transport them to the welding station along a set trajectory.

[0030] Transfer agencies, including:

[0031] The second lifting cylinder is installed below the chain conveyor mechanism. It is activated after the number of pipes accumulates to a set number, lifting the pipes as a whole and detaching them from the chain conveyor mechanism.

[0032] The push cylinder, located on the side of the second lifting cylinder, pushes the pipe in the horizontal direction after the pipe is lifted, so that it enters the welding station.

[0045] To enhance understanding of this utility model, the present utility model will be further described in detail below with reference to the embodiments and accompanying drawings. These embodiments are only used to explain the present utility model and do not constitute a limitation on the scope of protection of the present utility model.

[0046] A multi-process processing line device for pipe products includes a transfer assembly 5, a worktable 1, multiple working mechanisms such as a cutting R assembly 2, a flattening assembly 3, a plugging assembly 4, a transmission assembly 6, a welding table 7, and a control system, realizing automated multi-process processing of pipe fittings.

[0047] The workbench 1 of this equipment is divided into two platforms, left and right, according to the equipment layout of the in-line process. They are connected by a steel pipe in the middle to form a stable working platform. The platform is equipped with multiple sets of fixing blocks for fixing the pipes. Each set has two fixing blocks, which are located at the processing position of each working mechanism to ensure the stable positioning of the pipes during processing.

[0048] The transfer assembly 5 is used to move pipe fittings between processes. It includes a slide rail 51, a telescopic cylinder 52, a first lifting cylinder 53, a support frame 54, a sliding plate 55, a slider 56, a connecting plate 57, and a positioning block 58. The slide rail 51 is fixed to the equipment structure, providing linear guidance for the movement of the pipe fittings. One end of the telescopic cylinder 52 is fixed to the slide rail 51, and the other end is connected to the sliding plate 55, which drives the sliding plate 55 to slide on the slide rail, realizing the horizontal transfer of the pipe fittings. The first lifting cylinder 53 is fixedly connected to the sliding plate 55 through the connecting plate 57, and its telescopic end is connected to the floating joint of the support frame 54. The support frame 54 is used to support the pipe fittings to be transferred, and the positioning block 58 restricts the swinging or rolling of the pipe fittings, ensuring the stability of the pipe fittings during the transfer process.

[0049] The component (5) has been divided into two groups, left and right, to ensure stable transmission.

[0050] The pipe fitting is first placed on the support frame 54 and fixed in position by the positioning block 58. The telescopic cylinder 52 drives the slide plate 55 to slide back and forth along the slide rail 51, realizing the horizontal transfer of the pipe fitting. After the slide plate 55 moves to the target position, the first lifting cylinder 53 extends, lifts the pipe fitting through the support frame 54, and sends it to the corresponding processing station. After the current process is completed, the control system drives the transfer assembly 5, so that the pipe fitting enters the cutting, flattening, plugging and welding processes in sequence according to the set process. The welded pipe fitting is transported to the next stage through the transfer assembly 6, thereby realizing the automation of the entire processing flow.

[0051] The number of material support racks 54 matches the number of working mechanisms, and the spacing between the material support racks 54 corresponds to the spacing between the working mechanisms, enabling the pipe fittings to enter each process precisely. The transfer assembly 5 also includes photoelectric sensors to detect the current position of the pipe fittings and to link with the control system to achieve precise transfer.

[0052] After the pipe fittings have completed the aforementioned processing, they are conveyed to the welding station by the transmission assembly 6. The transmission assembly 6 includes a feeding mechanism 61, a chain conveying mechanism 62, and a transfer mechanism 63. The feeding mechanism 61 receives the pipe fittings conveyed by the transfer assembly 5 and guides them into the chain conveying mechanism 62. The chain conveying mechanism 62 uses a chain drive to arrange the pipe fittings using equally spaced pipe-blocking devices and conveys them to the welding station along a set trajectory. The transfer mechanism 63 includes a second lifting cylinder 631, a pushing cylinder 632, and a pallet 633, used to transfer the pipe fittings as a whole after a set number has accumulated, causing them to detach from the chain conveying mechanism and be pushed into the welding station, ensuring stable movement of the pipe fittings.

[0053] The control system is used to control the operation of each component to achieve automated processing of pipe fittings. The control system also includes a human-machine interface that can display the real-time operating status of the transfer component 5 and the transmission component 6, and allows the operator to manually adjust the transfer parameters to adapt to the processing requirements of pipe fittings of different specifications.

[0054] In addition, the upper surfaces of both the positioning block and the fixing block are provided with mounting grooves for limiting the pipe fittings, so as to further improve the fixing accuracy of the pipe fittings and ensure the processing quality.

[0055] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. 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.
