Description

Technical Field

[0001] This invention relates to a metal composite pipe production equipment, and more specifically, to an automatic processing device and method for the outer port of a metal-clad pipe. Background Technology

[0002] Currently, the market has increasingly higher requirements for the overall quality of composite pipes, metal composite pipes, and stainless steel composite pipes. This not only places strict demands on the manufacturing quality of the products but also on their performance in application. At present, there are still many defects in the production and application of metal composite pipes, especially in the area of ​​installation and connection. If the ends of the composite pipes are not properly treated, it will directly affect the quality of the composite pipes in engineering applications. The common practice now is to manually process the ends of metal composite pipes, which is inefficient and yields poor results. Summary of the Invention

[0003] To overcome the above shortcomings, the present invention provides an automatic processing device and method for the outer port of a metal-clad tube. The processing operation of the outer port of the metal-clad tube is convenient, greatly improving work efficiency and providing good processing results.

[0004] To solve the above-mentioned technical problems, the present invention adopts the following technical solution: an automatic processing device for the outer layer port of a metal-clad tube, comprising a frame and two port processing mechanisms respectively installed on the front and rear sides of the frame. The port processing mechanism includes a movable seat and a positioning chuck for clamping the metal-clad tube. A turntable is installed on the movable seat, and a ring cutter and a peeling chuck are installed on the turntable. The turntable rotates to cause the ring cutter to ring cut the outer layer of the metal-clad tube. The peeling chuck clamps the ring-cut outer layer of the metal-clad tube, and the ring-cut outer layer of the metal-clad tube is removed from the metal-clad tube as the movable seat moves.

[0005] During the cutting operation of the outer coating layer at both ends of the metal-clad tube, the two ends of the metal-clad tube are first clamped and positioned by the positioning chucks of the two-end processing mechanism. Then, the moving seat is moved laterally into position, so that the turntable, circumferential cutting blade, and peeling chuck are in place. The turntable rotates and the circumferential cutting blade moves radially to circumferentially cut the outer layer of the metal-clad tube. After the outer layer of the cladding tube is circumferentially cut, the circumferential cutting blade returns to its original position, and the turntable stops rotating. The peeling chuck moves radially to hold the circumferentially cut outer layer of the metal-clad tube. The moving seat moves in the opposite direction to its original position while the turntable rotates, causing the circumferentially cut outer layer of the metal-clad tube to detach from the metal-clad tube. The peeling chuck returns to its original position, and the positioning chuck also returns to its original position. The entire processing process of the outer layer of the metal-clad tube is convenient to operate, improving work efficiency. Moreover, the rotating circumferential cutting blade produces a clean cut, and the peeling chuck holds the circumferentially cut outer layer of the cladding tube while rotating and pulling it outward, making peeling convenient and reliable, thus ensuring the processing effect of the outer layer of the metal-clad tube. The turntable is driven by a motor to rotate, and the movement of the moving seat can be achieved by a piston cylinder. The movement of the positioning chuck, the ring cutter, and the peeling chuck can also be achieved by a piston cylinder, which greatly improves the automation level of the entire equipment.

[0006] Preferably, a ring-cutting piston cylinder is installed on the turntable corresponding to the ring-cutting blade, and a blade holder is installed on the telescopic rod of the ring-cutting piston cylinder. The ring-cutting blade has a ring structure and is rotatably mounted on the blade holder.

[0007] The telescopic movement of the circumferential cutting piston cylinder enables the radial movement of the circumferential cutting blade. The annular circumferential cutting blade is rotatably mounted on the blade holder. It can rotate when cutting the outer layer of the metal-clad tube, reducing cutting resistance and preventing the circumferential cutting blade from jamming and damaging the metal-clad tube.

[0008] Preferably, the turntable is provided with a sliding groove corresponding to the circumferential piston cylinder, and a radially movable slide block is installed in the sliding groove. The circumferential piston cylinder is fixedly installed on the slide block. An adjusting screw is installed on the turntable, and the slide block is connected to the adjusting screw. The movement of the slide block is achieved by rotating the adjusting screw.

[0009] The slide can move radially within a groove on the turntable, thereby adjusting the installation position of the circumferential piston cylinder. This allows for a wider range of applicable metal-clad pipe diameters, increasing the overall versatility of the device. The slide can be moved by rotating the adjusting screw, making operation convenient and the movement reliable.

[0010] Preferably, the positioning chuck includes a fixed chuck and a movable chuck arranged opposite to each other, the movable chuck is connected to the telescopic rod of the positioning piston cylinder, and the metal-clad tube is clamped between the fixed chuck and the movable chuck.

[0011] When the metal-clad tube is clamped and positioned, the telescopic rod of the positioning piston cylinder moves to bring the movable clamp closer to the fixed clamp, thereby tightly clamping the metal-clad tube between the fixed clamp and the movable clamp, making clamping convenient and reliable.

[0012] Preferably, there are two peeling chucks arranged opposite each other, and the opposite surfaces of the two peeling chucks are V-shaped. Peeling piston cylinders are installed on the turntable corresponding to the peeling chucks, and the peeling chucks and peeling piston cylinders are connected by telescopic rods.

[0013] The V-shaped two-pronged peeling jaws hold the cut-off metal-clad outer layer of the tube reliably. The radial movement of the peeling jaws is achieved through the telescopic movement of the peeling piston cylinder, ensuring precise and reliable movement.

[0014] Preferably, the turntable is provided with an adjustment groove corresponding to the peeling piston cylinder, and an adjustment seat that is radially movable is installed in the adjustment groove. The peeling piston cylinder is fastened to the adjustment seat. An adjustment screw is installed on the turntable, and the adjustment seat is connected to the adjustment screw. The adjustment screw rotates to move the adjustment seat.

[0015] The adjusting seat can move radially within the adjusting groove on the turntable, thereby adjusting the installation position of the stripping piston cylinder. This allows for a wider range of applicable metal-clad pipe diameters, increasing the overall versatility of the device. The adjusting seat can be moved by rotating the adjusting screw, making operation convenient and reliable.

[0016] Preferably, a positioning support is installed on the turntable corresponding to the circumferential cutting blade, and two positioning wheels for supporting the metal-coated tube are installed on the positioning support.

[0017] When the circumferential cutter cuts the metal-clad tube, the two positioning wheels provide excellent support for the metal-clad tube at the cutting position, ensuring reliable cutting.

[0018] Preferably, a support piston cylinder is installed on the turntable corresponding to the positioning support, and the telescopic rod of the support piston cylinder is connected to the positioning support.

[0019] The radial movement of the positioning support is achieved by supporting the piston cylinder, ensuring smooth and reliable movement.

[0020] Preferably, the turntable has a receiving cavity, the end of the metal-clad tube is placed in the receiving cavity, and an axially movable push rod is installed on the inner wall of the receiving cavity. The push rod abuts against the end of the metal-clad tube. The peeling piston cylinder is fastened to a coil spring seat and a locking seat. A coil spring is installed in the coil spring seat, and a pull rope is connected between the coil spring and the push rod. The pull rope passes through the locking seat, and a movable pressure block is installed on the locking seat. There is a gap between the locking seat and the pressure block for the pull rope to pass through. A positioning spring is installed between the locking seat and the pressure block. An inclined pushing surface is provided at the outer end of the pressure block, and a pushing block is provided in the peeling chuck. The peeling chuck moves towards the metal-clad tube so that the pushing block abuts against the pushing surface, and the pressure block moves towards the pull rope and presses the pull rope between the pressure block and the locking seat.

[0021] In the initial stage, the pull rope is pulled by the spring, causing the push rod to move to the opening of the receiving cavity. During the movement of the moving seat, the push rod comes into contact with the end of the metal-clad tube and is pushed by the metal-clad tube. After the ring cutter completes the cutting of the outer layer of the metal-clad tube, the extension and retraction of the peeling piston cylinder extends outward, driving the peeling chuck to move towards the metal-clad tube. During this process, the push block abuts against the push surface, and the pressure block moves towards the pull rope and presses the pull rope between the pressure block and the locking seat. At this time, the pull rope is not pulled by the spring. In subsequent operations, the push rod and the turntable move synchronously, and the push rod does not obstruct the peeled outer layer of the metal-clad tube, ensuring reliable peeling of the outer layer of the metal-clad tube. After the outer layer of the metal-clad tube is completely peeled off, the peeling clamp moves back to its original position, the pushing block separates from the pushing surface, and the pressure block returns to its original position under the action of the positioning spring, increasing the gap. The pull rope is then pulled by the coil spring. At this point, the push rod abuts against the end of the peeled-off outer layer of the metal-clad tube. The push rod, pulled by the coil spring, pushes the peeled-off outer layer of the metal-clad tube outward from the receiving cavity and falls down. This structural design ensures the reliable falling of the peeled-off outer layer of the metal-clad tube, preventing it from remaining in the receiving cavity and affecting subsequent operations.

[0022] An automatic processing method for the outer port of a metal-clad tube, comprising the following steps: (The method utilizes an automatic processing device for the outer port of the metal-clad tube.)

[0023] S1, the metal-clad tube is cut and falls onto the machine frame after being cut in the previous process;

[0024] S2, After the metal-clad tube is moved into place, the positioning chucks of the two-port processing mechanism clamp and position the two ends of the metal-clad tube.

[0025] S3, the moving seat moves laterally, so that the turntable and the ring cutter move axially into place together;

[0026] S4, the turntable rotates and the circumferential cutting blade moves radially to circumferentially cut the outer layer of the metal-clad tube;

[0027] S5, after the outer layer of the metal-clad tube is circumferentially cut, the circumferential cutting blade returns to its original position and the turntable stops rotating;

[0028] S6, the peeling chuck moves radially to hold the outer layer of the circumferentially cut metal-clad tube, the moving seat moves in the opposite direction to return to its original position, and the turntable rotates, so that the outer layer of the circumferentially cut metal-clad tube is detached from the metal-clad tube.

[0029] S7, peeling chuck return, positioning chuck return.

[0030] The entire process of processing the outer end of the metal-clad tube is convenient and improves work efficiency. Moreover, the rotating circumferential cutter makes a clean cut, and the peeling chuck holds the cut outer layer of the tube while rotating and pulling it outward, making peeling convenient and reliable, thus ensuring the processing effect of the outer end of the metal-clad tube.

[0031] Compared with the prior art, the beneficial effects of the present invention are: (1) the processing operation of the outer port of the metal-coated tube is convenient, which greatly improves the work efficiency and the processing effect is good; (2) the outer layer of the metal-coated tube cut off from the end of the metal-coated tube is easy to peel off and will not remain on the turntable after peeling.
