Description

Technical Field

[0001] This invention relates to a pipe processing technology, and more specifically, to an automatic pipe end face processing device and method. Background Technology

[0002] Currently, the market demands increasingly higher overall quality from composite pipes. The equipment used in the original composite pipe production process employed saw blade cutting and chipless cutting methods, resulting in unsatisfactory appearance quality at the cut edges, failing to meet quality requirements. To improve the appearance quality of the cut edges, end-face treatment is often necessary. However, there is currently no dedicated equipment for pipe end-face treatment, and most methods rely on manual methods, leading to low work efficiency. Furthermore, the quality of pipe end-face treatment is heavily dependent on the workers' skill level, making it difficult to guarantee quality. Summary of the Invention

[0003] To overcome the above shortcomings, the present invention provides an automatic pipe end face processing device and method. The automatic processing of pipe end faces improves work efficiency, ensures the processing quality of pipes, and helps to improve the economic benefits of enterprises.

[0004] To solve the above-mentioned technical problems, the present invention adopts the following technical solution: an automatic pipe end face processing device, comprising a frame for supporting pipes and two pipe processing units arranged opposite to each other on the frame. Each pipe processing unit includes a rotary cutter holder, a lower translation stage, and an upper translation stage movably mounted on the lower translation stage. A lower pushing mechanism for driving the lower translation stage is mounted on the frame. An upper pushing mechanism for driving the upper translation stage is mounted on the lower translation stage. A clamping head for clamping the pipe is mounted on the lower translation stage, and a driver for driving the rotary cutter holder to rotate is mounted on the upper translation stage. A cutting tool is connected to the rotary cutter holder.

[0005] During the pipe end-face finishing process, the pipe, cut in the previous process, is loaded onto the machine frame. The lower push mechanism of the two pipe processing units drives the lower translation stage to move into position towards the pipe. The clamping heads on the two pipe processing units clamp and position both ends of the pipe. The upper push mechanism drives the upper translation stage to move towards the pipe, and the driver rotates the rotary cutter holder. The cutter on the rotary cutter holder engages with the pipe end for finishing. After the pipe end-face finishing is completed, the upper translation stage moves back to its original position, the clamping heads release the pipe, and the lower translation stage moves back to its original position. The pipe is then unloaded from the machine frame. This automated pipe end-face processing improves work efficiency. Furthermore, the precise control of the movement position and distance during the processing ensures the quality of the processed pipe, which is beneficial to improving the company's economic benefits.

[0006] Preferably, the lower-level pushing mechanism includes a lower slider, a lower screw, and a lower motor. The output shaft of the lower motor is connected to the lower screw, the lower screw is threadedly connected to the lower slider, and the lower slider is fastened to the lower-level translation stage.

[0007] The lower motor drives the lower screw to rotate, which in turn drives the lower slider to move, thereby realizing the lateral movement of the lower translation stage.

[0008] Preferably, the upper pushing mechanism includes an upper slider, an upper screw, and an upper motor. The output shaft of the upper motor is connected to the upper screw, the upper screw is threadedly connected to the upper slider, and the upper slider is fastened to the upper translation stage.

[0009] The upper motor drives the upper screw to rotate, which in turn drives the upper slider to move, thereby realizing the lateral movement of the upper translation stage.

[0010] Preferably, the driver includes a drive motor and a rotating shaft. The drive motor is connected to the rotating shaft, which is rotatably mounted on the upper translation stage. The rotating tool holder is mounted on one end of the rotating shaft.

[0011] The drive motor rotates to make the rotating shaft rotate, and the rotating tool holder rotates together with the rotating shaft.

[0012] Preferably, the clamping head includes an upper clamp and a lower clamp. The upper clamp is connected to clamp the extension rod of the piston cylinder, and both the clamping piston cylinder and the lower clamp are securely connected to the lower translation stage.

[0013] The clamping piston cylinder drives the upper chuck to move, thereby clamping and releasing the pipe, ensuring reliable clamping operation.

[0014] Preferably, a feeding rack is provided on one side of the frame, and a conveyor belt, a pushing piston cylinder, and a positioning baffle are installed on the feeding rack. The positioning baffle is placed above the conveyor belt to block the pipes. The telescopic rod of the pushing piston cylinder is connected to a push plate, which is used to push the pipes on the conveyor belt.

[0015] When the pipes conveyed by the conveyor belt touch the positioning baffle, the pusher piston cylinder telescopic rod extends outward, and the pusher plate pushes the pipes on the conveyor belt onto the frame, completing the automatic feeding of the pipes. The feeding is convenient and reliable.

[0016] Preferably, a discharge rack is provided on the other side of the frame, and the discharge rack is provided with an inclined support rod, with a vertical rod at the end of the support rod for blocking the pipe.

[0017] After the pipe end is finished, the pipe on the frame slides down onto the unloading rack. The support rods on the unloading rack support the pipe, and the uprights block and limit the pipe.

[0018] Preferably, a pipe support and a liftable pipe discharge lifting seat are installed on the frame. The pipe discharge lifting seat is connected to a lifting piston cylinder. The pipe support supports the pipe, and the pipe discharge lifting seat lifts the pipe upward to realize the unloading of the pipe.

[0019] The pipe is pushed from the conveyor belt onto the frame, where the pipe support supports the pipe. After the pipe end is finished, the pipe lifting seat moves upward to lift the pipe, causing it to slide automatically onto the unloading rack.

[0020] Preferably, the rotary tool holder is provided with a mounting hole, which is connected to a push column that is axially movable. A positioning spring is connected between one end of the push column and the mounting hole, and the other end of the push column is connected to a rotatable positioning column. The positioning column is fitted into the end of the tube.

[0021] Because the pipes are long and many composite pipes are not rigid, their coaxiality is poor after being loaded onto the frame, which would affect machining accuracy if processed directly. In this solution, when the lower-level push mechanism drives the lower-level translation stage to move towards the pipe, the positioning pin is inserted into the pipe end. When the clamping head clamps and positions the pipe, the position of the positioning pin on the pipe is held by the clamping head, preventing deformation of the clamped position and ensuring good coaxiality at the pipe end. The upper-level translation stage moves towards the pipe, causing axial movement between the rotary tool holder and the push pin. The driver drives the rotary tool holder and the push pin to rotate together, and the tool on the rotary tool holder engages with the pipe end for finishing. Because the positioning pin positions the pipe end, the coaxiality at the pipe end is good, which helps improve machining accuracy and thus product quality. After the pipe finishing is completed, the upper-level translation stage moves back to its original position, the clamping head releases the pipe, the lower-level translation stage moves back to its original position, and the positioning pin disengages from the pipe.

[0022] An automatic pipe end face processing method, which uses an automatic pipe end face processing device to perform end face processing on pipes, includes the following steps:

[0023] S1, Load the pipes that have been cut in the previous process onto the frame;

[0024] S2, the lower-level pushing mechanism of the two pipe processing units drives the lower-level translation stage to move into place in the direction of the pipe;

[0025] S3, the clamping heads on the two pipe processing units clamp and position the two ends of the pipe respectively;

[0026] S4, the upper push mechanism drives the upper translation stage to move towards the pipe, the driver drives the rotary tool holder to rotate, and the tool on the rotary tool holder comes into contact with the pipe end to perform flat end processing.

[0027] S5, after the pipe end processing is completed, the upper translation table moves back to its original position in the opposite direction, the clamping head releases the pipe, and the lower translation table moves back to its original position in the opposite direction.

[0028] S6 unloads the pipes from the frame.

[0029] Automated pipe end face processing improves work efficiency. Furthermore, precise control of movement position and distance during processing ensures the quality of pipe processing, which in turn improves the company's economic benefits.

[0030] Compared with the prior art, the beneficial effects of the present invention are: (1) Automatic processing of pipe end face improves work efficiency, ensures the processing quality of pipe, and is conducive to improving the economic benefits of enterprises; (2) Good coaxiality of pipe end position is conducive to improving processing accuracy, thereby improving product quality.

[0042] The driver includes a drive motor 33 and a rotating shaft 34. The drive motor is driven by the rotating shaft, which is rotatably mounted on the upper translation stage. A rotary tool holder is mounted on one end of the rotating shaft. The drive motor output shaft and the rotating shaft can be driven by a belt or gear. The clamping head includes an upper clamp 35 and a lower clamp 36, both of which are C-shaped. The upper clamp is connected to the telescopic rod of the clamping piston cylinder 37. Both the clamping piston cylinder and the lower clamp are securely connected to the lower translation stage.

[0043] An automatic pipe end face processing method, which uses an automatic pipe end face processing device to perform end face processing on pipes, includes the following steps:

[0044] S1, load the pipes cut in the previous process onto the frame; during transfer, the pipes are first conveyed on the conveyor belt. After the end of the pipe touches the touch sensor on the positioning baffle, the pusher piston cylinder is activated to complete one extension and retraction movement of the pusher piston cylinder telescopic rod, so that the pusher plate pushes the pipes on the conveyor belt onto the pipe support on the frame for support.

[0045] S2, the lower push mechanism of the two pipe processing units works, the lower motor rotates to drive the lower translation table to move into place in the direction of the pipe;

[0046] S3, the clamping heads on the two pipe processing units clamp and position the two ends of the pipe respectively; the extension rod of the clamping piston cylinder extends to move the upper clamp toward the pipe, and clamps the pipe tightly between the upper clamp and the lower clamp.

[0047] S4, the upper push mechanism works, the upper motor rotates to drive the upper translation stage to move towards the pipe, when the drive motor of the driver works, the rotating shaft rotates, driving the rotating tool holder to rotate, and the tool on the rotating tool holder abuts against the pipe end to perform flat end processing.

[0048] S5, after the pipe end processing is completed, the upper translation table moves back to its original position, the clamping piston cylinder returns to its original position, the clamping head releases the pipe, and the lower translation table moves back to its original position.

[0049] S6 unloads the pipes from the frame; the lifting piston cylinder moves the pipe lifting seat upward, lifting the pipes upward, so that the pipes automatically slide down onto the unloading rack.

[0050] Example 2: An automatic pipe end face processing device (see attached) Figure 4Its structure is similar to that of Embodiment 1, with the main difference being that the rotating tool holder in this embodiment has a mounting hole 38, which is connected to an axially movable push column 39. A positioning spring 40 is connected between one end of the push column and the mounting hole, and a rotatably mounted positioning column 41 is connected to the other end of the push column.

Other structures are the same as in Embodiment 1.

[0051] An automatic pipe end face processing method, the steps of which are similar to those of Embodiment 1, the main difference being that in this embodiment, when the lower-level pushing mechanism drives the lower-level translation stage to move towards the pipe in S2, the positioning pin is inserted into the pipe end, with the outer end of the positioning pin close to the pipe port and retracted inside the pipe. In S3, when the clamping head clamps and positions the pipe, the position of the positioning pin inserted on the pipe is held by the clamping head, making the clamped position less prone to deformation and ensuring good coaxiality of the pipe end. In S4, when the upper-level translation stage moves towards the pipe, the rotating tool holder and the pushing pin move axially, and the driver drives the rotating tool holder and the pushing pin to rotate together. The tool on the rotating tool holder abuts against the pipe port for end face processing. Because the positioning pin positions the pipe end, the coaxiality of the pipe end is good, which helps improve processing accuracy and thus product quality. In S5, after the pipe end face processing is completed, the upper-level translation stage moves back to its original position, the clamping head releases the pipe, the lower-level translation stage moves back to its original position, and the positioning pin disengages from the pipe. The other steps are the same as in Example 1.
