Description

Technical Field

[0001] The invention relates to the technical field of cutting equipment, in particular to a metal corrugated pipe cutting and processing device. Background Art

[0002] Metal bellows is a metal pipe product used for connection, displacement compensation and vibration absorption. It is usually made of stainless steel and has the advantages of good corrosion resistance, high temperature resistance and easy installation. It is widely used in technical fields such as pipeline connection, thermal expansion compensators, medium transportation and flexible connectors. Metal bellows often need to be cut to a fixed length during use. However, there are certain problems in the cutting process: 1. During the cutting process of existing cutting equipment, the metal bellows needs to be crimped and fixed, but the metal bellows itself has elastic and retractable characteristics. After the metal bellows is crimped and fixed, it cannot be guaranteed to be in a straight state. The metal bellows after crimping and fixing may be over-stretched or bent, resulting in inaccurate cutting length, resulting in different lengths of metal bellows in different batches.

[0003] 2. Since the metal bellows itself is elastic and retractable, during the cutting process, the saw blade generates radial cutting force on the metal bellows, which can easily cause the bellows to slip, resulting in the problem of skewed cutting.

[0004] 3. Nowadays, the cutting equipment on the market usually cuts a single metal corrugated pipe to a fixed length, which has low work efficiency. At the same time, after cutting, it is necessary to use an automatic feeding mechanism for feeding. When feeding, the feeding timing of the feeding mechanism needs to be manually controlled or controlled by a computer program, which is laborious and costly. Summary of the invention

[0035] See also Figure 1 , Figure 2 , Figure 3 and Figure 4 The self-compensating clamping mechanism 4 includes a fixed clamping component 41 for clamping and fixing the end side of the metal bellows and an automatic compensation component 42 for adaptively compensating and clamping the metal bellows. A number of No. 1 fixed blocks 411 are evenly installed on the top of the No. 2 pad 8, and two No. 1 side blocks 413 are symmetrically installed on the top of the No. 1 fixed block 411. A No. 1 clamping spring 412 is installed at the center of the opposite side of the two No. 1 side blocks 413, and a No. 1 mounting block 415 is installed on the opposite side of the two No. 1 clamping springs 412; a No. 1 clamping arc block 414 is installed on the opposite side of the two No. 1 mounting blocks 415, and the two No. 1 clamping arc blocks 414 clamp and fix the metal bellows together. A number of No. 2 fixed blocks 429 are evenly installed on the top of the No. 1 pad 7, and the No. 2 fixed blocks 429 are evenly installed on the top of the No. 1 pad 7. Two limiting rails 425 are symmetrically installed on the top of the fixed block 429, and sliders 424 are slidably connected to the two limiting rails 425, and No. 2 side blocks 422 are installed on the tops of the two sliders 424, and No. 2 clamping springs 426 are installed at the centers of the opposite sides of the two No. 2 side blocks 422, and No. 2 mounting blocks 427 are installed on the opposite sides of the two No. 2 clamping springs 426, and No. 2 clamping arc blocks 428 are installed on the opposite sides of the two No. 2 mounting blocks 427, and the metal bellows are clamped together between the two No. 2 clamping arc blocks 428, and compensation springs 423 are installed on the left sides of the two No. 2 side blocks 422, and an annular block 421 is installed on the left ends of the two compensation springs 423, and the bottom of the annular block 421 is fixedly connected to the left side of the top of the No. 2 fixed block 429.

[0036] During use of the self-compensating clamping mechanism 4, first pull the No. 2 clamping arc block 428 toward the direction of the No. 2 side block 422, then drive the No. 2 mounting block 427 to move toward the direction of the No. 2 side block 422, and then compress the No. 2 clamping spring 426 to separate the No. 2 clamping arc block 428. At this time, the metal bellows is inserted from the center of the annular block 421, and then passed between the two No. 2 clamping arc blocks 428, and the No. 2 clamping arc block 428 is released. Under the action of the restoring force of the No. 2 clamping spring 426, flexible clamping of the metal bellows is achieved, and then the metal bellows is passed through the feeding mechanism 6 and the limiting and shaping mechanism 5, and then the No. 1 clamping arc block 414 is pulled toward the direction of the No. 1 side block 413, and then the metal bellows is passed between the two No. 1 clamping arc blocks 414. At this time, the No. 1 clamping arc block 414 is released. Under the elastic force of spring 412, the other end of the metal bellows is clamped and fixed. After clamping, when the metal bellows bends, under the elastic force of compensation spring 423, the No. 2 side block 422 is driven to move in the direction of the annular block 421, and then the No. 2 clamping spring 426 is driven to move in the direction of the annular block 421, indirectly driving one end of the metal bellows to move in the direction of the annular block 421, which is beneficial to achieve compensatory straightening of the metal bellows. When the metal bellows is over-stretched, the No. 2 clamping arc block 428 moves in the direction of the No. 1 fixed block 411, indirectly driving the No. 2 side block 422 to move along the limiting track 425 toward the direction of the No. 1 fixed block 411, which is beneficial to achieve automatic compensation of the length of the metal bellows, avoids excessive stretching or bending of the metal bellows, and improves the accuracy of cutting the metal bellows.

The two output ends of the two-way cylinder 512 are installed with connecting rods 513, and the two connecting rods 513 are installed on the opposite sides of the shaping and limiting components 52; the shaping and limiting component 52 includes a fixing frame 521, the fixing frame 521 is installed on the opposite side of the two connecting rods 513, and the two fixing frames 521 are installed on the opposite sides of the two fixing frames 521. A plurality of arc-shaped limiting clamping plates 523 are installed on the opposite sides of the four mounting rods 522, and a group of arc-shaped limiting clamping plates 523 corresponding to the upper and lower sides are installed. The clamping plates 523 jointly clamp the metal bellows, and a fixed rod 10 is installed on the left side of the connecting rod 513 located at the top, and a No. 1 linkage rod 9 is installed at the bottom of the fixed rod 10, and the bottom of the No. 1 linkage rod 9 passes through the rear side of the top of the workbench 1, and a No. 2 linkage rod 12 is installed on the right side of the connecting rod 513 located at the bottom. A positioning rod 11 is hingedly installed on the top of the workbench 1 on the right side of the fixed clamping assembly 41 through a torsion spring rod, and the top of the positioning rod 11 passes through the top of the workbench 1, and the positioning rod 11 is in contact with the outer wall of one of the metal bellows, and an inclined guide block is installed at the bottom of the positioning rod 11. When the guide block is in close contact with the No. 2 linkage rod 12, the positioning rod 11 is in a vertical state, and a through groove for the positioning rod 11 to rotate is provided on the top of the workbench 1.

[0038] After the two ends of the metal bellows are clamped and fixed by the self-compensating clamping mechanism 4, the limiting and shaping mechanism 5 is used to limit and position the two sides of the metal bellows to be cut. At this time, the output end of the two-way cylinder 512 begins to shrink, and then indirectly drives the arc-shaped limiting clamping plate 523 to move centripetally through the connecting rod 513, the fixing frame 521 and the installation rod 522. The arc-shaped limiting clamping plate 523 is used to limit and clamp the two ends of the metal bellows to be cut symmetrically in the upper and lower directions. The clamping and fixing of the self-compensating clamping mechanism 4 is combined to improve the stability of the clamping and installation of the metal bellows. In addition, the setting of the limiting and shaping mechanism 5 avoids the slippage of the metal bellows.

[0039] See also Figure 1 and Figure 5The multiple cutting mechanisms 3 include slide rails 35, which are provided with two slide rails 35 and are symmetrically installed on the top side wall of the workbench 1.

[0040] After the limiting and shaping mechanism 5 limits and positions the two ends of the metal corrugated tube in the area to be cut, the output end of the driving motor 32 rotates, driving the active sprocket 39 to rotate rapidly, indirectly driving the driven sprocket 36 to rotate, and then driving the cutting saw blade 33 to rotate. At this time, the output end of the hydraulic telescopic rod 31 extends, driving the slide 38 to move along the slide rail 35, and then driving the mounting seat 37 to move along the slide rail 35, and then driving the cutting saw blade 33 to move along the slide rail 35, so that the cutting saw blade 33 is used to cut through the gap between the arc-shaped limiting clamping plates 523, thereby realizing integrated cutting of multiple metal corrugated tubes with high cutting efficiency.

[0041] See also Figure 1 , Figure 6 and Figure 7The feeding mechanism 6 includes a feeding assembly 61 and a power assembly 62. The feeding assembly 61 includes a mounting frame 615. The mounting frame 615 is mounted at the top center of the workbench 1, and the power assembly 62 is mounted at the bottom of the mounting frame 615. A plurality of center shafts 616 are evenly mounted on the top of the mounting frame 615. The center shaft 616 is rotatably connected to the mounting frame 615. A driven extrusion feeding wheel 611 is mounted on the top of the center shaft 616. A plurality of connecting shafts 613 are evenly mounted on the top of the mounting frame 615. The bottom of the connecting shaft 613 passes through the bottom of the mounting frame 615. The connecting shaft 613 is rotatably connected to the mounting frame 615. An active extrusion feeding wheel 612 is mounted on the top of the connecting shaft 613. The active extrusion feeding wheel 612 is rotatably connected to the driven extrusion feeding wheel 611. The active extrusion loading wheels 611 correspond one to one, and the metal bellows are fitted together between the one-to-one active extrusion loading wheels 612 and the driven extrusion loading wheels 611. A worm gear 614 is installed at the bottom end of the connecting shaft 613. The power component 62 includes a servo motor 621. The servo motor 621 is installed at the bottom rear side of the mounting frame 615. A rotating shaft 625 is installed at the output end of the servo motor 621. A push switch 622 is installed at the bottom of the servo motor 621, and a plurality of worms 623 meshing with the worm gear 614 are sleeved and fixed on the rotating shaft 625. A plurality of bearing ear blocks 624 are evenly sleeved on the rotating shaft 625, and the bearing ear blocks 624 are rotatably connected to the rotating shaft 625, and the bearing ear blocks 624 are installed on the upper surface of the workbench 1.

[0042] When the cutting of the metal bellows is completed, the output end of the two-way cylinder 512 extends, which then drives the output end of the fixed rod 10 to rise, and then drives the output end of the No. 1 linkage rod 9 to rise, and the No. 1 linkage rod 9 presses the push switch 622 on the servo motor 621, and the output end of the servo motor 621 starts to rotate, and then drives the rotating shaft 625 to rotate, and then drives the worm 623 to rotate, and then drives the worm gear 614 to rotate, thereby driving the connecting shaft 613 to rotate, and then drives the active extrusion feeding wheel 612 to rotate. The rotation of the active extrusion feeding wheel 612 drives the metal bellows to move in the direction of the fixed clamping assembly 41, and the metal bellows passes through the limiting shaping mechanism 5, thereby realizing the automatic feeding of the metal bellows. At the same time, the output end of the two-way cylinder 512 drives the No. 2 linkage rod 12 to move downward. After the servo motor 621 rotates for a certain period of time, the No. 2 linkage rod 12 moves down to a position where it does not contact the guide block of the positioning rod 11. At this time, the rear side of the top of the positioning rod 11 is in contact with the metal The side wall of the corrugated tube is fitted. During the feeding process, the metal corrugated tube to be cut pushes the already cut metal corrugated tube out of the fixed clamping assembly 41, thereby realizing the automatic unloading of the cut corrugated tube. When the cut corrugated tube is pushed out from the fixed clamping assembly 41, the top of the positioning rod 11 rotates toward the direction close to the metal bellows under the action of the torsion spring rod, so that the right end of the metal bellows to be cut conflicts with the left end of the positioning rod 11. At this time, the servo motor 621 is powered off, thereby stopping the feeding, ensuring the consistency of the feeding length, which is beneficial to fixed-length cutting. When the feeding is completed, the output end of the two-way cylinder 512 contracts, driving the No. 2 linkage rod 12 to move up, and the No. 2 linkage rod 12 re-extrudes the guide block, so that the positioning rod 11 returns to the vertical state. At the same time, the No. 1 linkage rod 9 moves down to release the extrusion on the press switch 622. The feeding mechanism 6 is linked with the limit shaping mechanism 5 to realize automatic feeding and ensure the fixed length of the feeding. A pressure sensor can be set at the left end of the positioning rod 11, and the pressure sensor is electrically connected to the servo motor 621. When the right end of the metal bellows to be cut collides with the left end of the positioning rod 11, the pressure sensor is squeezed by the metal bellows and sends a signal to the control system, thereby controlling the servo motor 621 to cut off power.

[0043] Working principle: During use, the present invention firstly uses the self-compensating clamping mechanism 4 to clamp and fix the two ends of the metal bellows. At the same time, the automatic compensation component 42 in the self-compensating clamping mechanism 4 automatically compensates for the clamping of the metal bellows, thereby avoiding bending or excessive stretching of the metal bellows during clamping, thereby improving the cutting accuracy. Subsequently, the limiting shaping mechanism 5 is used to clamp and fix the two sides of the metal bellows to be cut, thereby avoiding the metal bellows from slipping during cutting. The setting of the clamping mechanism 4 improves the stability of clamping, and then the multiple cutting mechanisms 3 are used to perform integrated cutting on the multiple metal bellows that have been clamped, with high cutting efficiency. After the cutting is completed, the limiting and shaping mechanism 5 releases the clamping and fixation of the metal bellows. At the same time, the No. 1 linkage rod 9 is linked with the limiting and shaping mechanism 5. The raising of the No. 1 linkage rod 9 realizes the pressing of the press switch 622, thereby opening the feeding mechanism 6, which is conducive to the automatic feeding of the metal bellows through the feeding mechanism 6 and ensures the consistency of the feeding length.
