Description

Technical Field

[0001] The invention relates to the technical field of plastic pipe cutting machines, in particular to a plastic pipe cutting machine capable of improving the stability of the pipe. Background Art

[0002] Plastic pipe is a kind of piping material widely used in construction, municipal administration, agriculture, water conservancy, chemical industry and other fields; Plastic pipe is a kind of piping material widely used in construction, municipal administration, agriculture, water conservancy, chemical industry and other fields; Plastic pipe is cut by laser cutting machine, which is a laser processing machine that irradiates the laser beam to the surface of the workpiece and uses the released energy to melt and evaporate the workpiece to achieve the purpose of cutting and engraving.

The unclamped part is easily tilted during cutting due to the influence of the plastic pipe's own gravity, thereby changing the cutting position and causing the cutting position to be uneven; and during cutting, the unclamped plastic pipe end is not supported, which will cause the cutting opening to become larger during cutting, and will also affect the cutting position.

[0016] (1) A plastic pipe cutting machine for improving the stability of pipes described in the present invention has two clamping mechanisms installed on the driving mechanism on the workbench. Before the cutting mechanism cuts the plastic pipe, the plastic pipe can be passed through the two fixed rings, and the cutting point can be placed at the middle position between the two fixed rings. The distance between the two fixed rings can be adjusted by the driving mechanism, thereby adjusting the distance between the clamping point and the cutting point. After determination, the motors on the two fixed plates are started to realize that the two motors rotate to drive a gear to rotate. When one gear rotates, the gear ring drives all the gears to rotate. Since the gear is meshed with the rack, the racks arranged in the circumferential array on the fixed ring move radially at the same time to complete the clamping of the plastic pipe, thereby ensuring the stability during cutting, avoiding the cutting opening from being widened during cutting and the plastic pipe at the cutting end tilting due to its own gravity, thereby affecting the cutting accuracy. During cutting, the fixed ring can be rotated to realize the rotation of the second magnetic ring on the first magnetic ring, and the first magnetic ring attracts the second magnetic ring, thereby increasing the resistance during rotation and cutting, thereby avoiding random rotation during cutting. With the rotation of the second magnetic ring, the clamped plastic pipe can rotate radially, thereby achieving all-round cutting and increasing accuracy.

When the pressure sensor collides with the plastic pipe, the machine stops rising. After the pressure sensor collides with the plastic pipe, the support plate on the connecting rod also collides with the plastic pipe, thereby increasing the support points for the plastic pipe.

When the cutting of the plastic pipe on the clamping mechanism is completed, the two fixing rings are moved away from each other by the driving mechanism. Then, the cut plastic pipe is divided into two sections. The two sections of the plastic pipe move away from each other along with the fixing rings, leaving a larger gap.

The driving mechanism is used to control the two grinding discs to contact the cross-sections of the two plastic pipes. The grinder is started to grind the cut surface to make the cut surface more neat. BRIEF DESCRIPTION OF THE DRAWINGS

[0030] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the present invention is further explained below in conjunction with specific implementation methods.

[0031] like Figure 1-Figure 9As shown, a plastic pipe cutting machine for improving the stability of pipes according to the present invention comprises a workbench 1, a cutting mechanism 2 installed on the workbench 1, a grinding mechanism 5, and a driving mechanism 3, wherein a clamping mechanism 4 is installed on the driving mechanism 3, two sets of supporting mechanisms 6 are relatively installed on the driving mechanism 3, and the grinding mechanism 5 is located between the two supporting mechanisms 6; the clamping mechanism 4 comprises two magnetic rings 401, the driving mechanism 3 is relatively fixedly connected with two magnetic rings 401, and the two magnetic rings 401 are relatively slidably connected with two magnetic rings 401. The two magnetic rings 401 and the two magnetic rings 403 are attracted to each other on their opposite surfaces. The opposite surfaces of the two magnetic rings 403 are fixedly connected with a fixing ring 402. The inner walls of the two fixing rings 402 are rotatably connected with a gear ring 405. The inner walls of the two fixing rings 402 are fixedly connected with a plurality of fixing plates 408. The plurality of fixing plates 408 are rotatably connected with a gear 406. The two fixing rings 402 are radially slidably connected with a plurality of racks 404. The racks 404 mesh with the gears 406. The gears 406 are meshed with each other. 06 is meshed with the gear ring 405, and a second motor 409 is installed on one of the fixing plates 408 on the two fixing rings 402, and the output ends of the two second motors 409 are fixedly connected to the two gears 406 respectively; the driving mechanism 3 includes an ash leakage port 306, and the surface of the workbench 1 is provided with an ash leakage port 306, and the inner wall of the workbench 1 is relatively provided with a slide groove 304 connected to the ash leakage port 306, and two slide plates 302 are slidably connected between the two slide grooves 304, and the inner wall of the workbench 1 is rotatably connected with a double slide plate 302. The two slide plates 302 are both threadedly connected to the bidirectional screw rod 305, and two support frames 303 are fixedly connected to the two slide plates 302. The two support frames 303 on the same side are respectively fixedly connected to the two magnetic rings 401. A first motor 301 is installed on the side wall of the workbench 1, and the output end of the first motor 301 is fixedly connected to the bidirectional screw rod 305. A discharge port 307 with an inclined bottom is provided inside the workbench 1, and the discharge port 307 is connected to the ash leakage port 306;When cutting the plastic pipe, the cutting position can be marked by a marking tool, and the plastic pipe can be passed through the inside of the two fixing rings 402 to determine that the cutting point is approximately in the middle position between the two fixing rings 402. The first motor 301 can be started to drive the bidirectional screw rod 305 to rotate. Since the two slides 302 are respectively connected to the two oppositely arranged threaded threads at the bidirectional screw rod 305, the two slides 302 can be driven to move relative to each other after the bidirectional screw rod 305 rotates. After the slides 302 move relative to each other, the two fixing rings 402 will also move relative to each other. The distance between the clamping point and the cutting point can be controlled by adjusting the distance between the two fixing rings 402. After adjusting the distance between the two fixing rings 402, the second motor 409 on the two fixing plates 408 is started at the same time. After the second motor 409 rotates, it drives one of the gears 406 to rotate. Since the gear 406 is meshed with the gear ring 405, the gear 406 driven by the second motor 409 drives the gear ring 405 inside the fixing ring 402. The gears 406 are further driven by the gear ring 405. Since the rack 404 is meshed with the gear 406, when the gears 406 rotate, the racks 404 move radially on the fixed ring 402 to clamp the plastic tube, so as to avoid a large opening at the cutting position during cutting and change the cutting position, and protect the two plastic tubes after cutting from falling and being damaged. When cutting, the magnetic ring 2 403 or the fixed ring 402 can be held, and the magnetic ring 2 403 is rotated in the circumferential direction to realize its rotation outside the magnetic ring 1 401, so as to adjust the cutting position in the circumferential direction, and the magnetic ring 1 401 and the magnetic ring 2 403 can be magnetically attracted to increase the resistance during movement and avoid the magnetic ring 2 403 from rotating randomly during cutting to affect cutting, and the radially sliding rack 404 can clamp and fix plastic tubes of different diameters, and the laser cutting machine body 202 on the mobile frame 201 can be used to cut the marked part of the plastic tube. After cutting, the two slide plates 302 can be driven by the first motor 301 to move back to each other and wait for polishing. ;

[0032] Specifically, the support mechanism 6 includes a mounting plate 601, and the opposite sides of the two slide plates 302 are fixedly connected with the mounting plate 601, and the two mounting plates 601 are installed with electric push rods 602, and the two electric push rods 602 are fixedly connected with arc-shaped support blocks 603, and the surfaces of the two support blocks 603 are installed with pressure sensors 604, and the support blocks 603 are co-centered with the fixing ring 402; the support mechanism 6 also includes a connecting rod 605, and the opposite sides of the two support blocks 603 are fixedly connected with two connecting rods 605, and the connecting rods on the same side The two connecting rods 605 are slidably connected with a plurality of support plates 608, the workbench 1 is relatively fixedly connected with two side plates 606, the tops of the two side plates 606 are fixedly connected with protective plates 607 that contact the connecting rods 605, and the surface of the support plates 608 is flush with the surface of the pressure sensor 604; the cutting mechanism 2 includes a moving frame 201, the workbench 1 is equipped with a moving frame 201, and the moving frame 201 is equipped with a laser cutting machine body 202; after the plastic pipe to be cut is clamped by the two sets of racks 404, the two mounting plates 601 can be started The electric push rod 602 of the second electric push rod 602 is extended, and the support block 603 is lifted up, and the pressure sensor 604 on the support block 603 also moves accordingly. When the pressure sensor 604 conflicts with the outer wall of the clamped plastic tube, the pressure sensor 604 can alarm. At this time, the electric push rod 602 can no longer rise. After the pressure sensor 604 conflicts with the outer wall of the plastic tube, further support is provided to the plastic tube. Since the support plate 608 on the connecting rod 605 on the side wall of the support block 603 is flush with the surface of the pressure sensor 604, when the pressure sensor 604 conflicts with the outer wall of the plastic tube, The support plates 608 will also come into conflict with the outer wall of the plastic tube. The multiple support plates 608 can be moved equidistantly to the two connecting rods 605 to support the two plastic tubes after cutting. The support points for the plastic tubes are also increased during cutting, which improves the stability during cutting and prevents the plastic tubes from falling directly after cutting, thereby protecting the plastic tubes. The most important thing is that the support plates 608 and the pressure sensors 604 will move with the movement of the slide plate 302, which means that the plastic tubes can be protected all the time. After clamping and supporting, the laser cutting machine body 202 on the mobile frame 201 is started to cut the cutting points of the plastic tubes.

[0033] Specifically, the grinding mechanism 5 includes a movable plate 501 and a movable groove 502. The movable frame 201 is provided with a movable groove 502, and the movable plate 501 is slidably connected to the movable groove 502. An electric push rod 508 is installed on the workbench 1, and the telescopic end of the electric push rod 508 is fixedly connected to the movable plate 501. The movable plate 501 is located between two fixed rings 402. Two hydraulic cylinders 503 are vertically installed on the movable plate 501. The telescopic ends of the two hydraulic cylinders 503 are fixedly connected to a mounting seat 505. A grinder 506 is installed on the top of the mounting seat 505. Grinding sheets 507 are installed at both ends of the grinder 506. Four limiting rods 504 slidably connected to the mounting seat 505 are fixed in a rectangular array on the movable plate 501. When the plastic pipe clamped by the two sets of racks 404 is cut, the two slide plates 302 can be controlled by the first motor 301 to move back to back. At this time, the two plastic pipes are also The two plastic tubes will move in opposite directions, and a larger space will be generated between the two plastic tubes, but the two plastic tubes are still clamped by the two sets of racks 404. The electric push rod 508 located on the workbench 1 is further started. The electric push rod 508 moves the moving plate 501 on the moving frame 201 to between the two fixed rings 402. When the two grinding discs 507 move to the bottom of the two plastic tubes, the two hydraulic cylinders 503 are started. After the hydraulic cylinders 503 rise, they push the grinder 506 to rise. When the two grinding discs 507 move between the two plastic tubes, the movement of the hydraulic cylinders 503 is stopped when the two grinding discs 507 can cover the cutting surface. The two slide plates 302 are controlled to move relative to each other by the first motor 301 again, so that the cutting surfaces of the two plastic tubes are contacted with the grinding discs 507. The grinder 506 is started to realize that the two grinding discs 507 grind the cutting surfaces of the plastic tubes to increase the flatness of the cutting. The grinding and cutting debris are discharged from the ash leakage port 306 to the inside of the discharge port 307.

[0034] When the present invention is in use, first, when cutting the plastic pipe, the cutting position can be marked by a marking tool, and the plastic pipe can be passed through the inside of the two fixed rings 402 to determine that the cutting point is located in the middle position between the two fixed rings 402 (approximately at), and the first motor 301 can be started to drive the bidirectional screw rod 305 to rotate. Since the two slides 302 are respectively connected to the two oppositely arranged threaded threads at the bidirectional screw rod 305, the rotation of the bidirectional screw rod 305 can drive the two slides 302 to move relative to each other. After the slides 302 move relative to each other, the two fixed rings 402 will also move relative to each other. The distance between the clamping point and the cutting point can be controlled by adjusting the distance between the two fixed rings 402. After adjusting the distance between the two fixed rings 402, the second motors 409 on the two fixed plates 408 are started at the same time. After the second motor 409 rotates, it drives one of the gears 406 to rotate. Since the gear 406 is meshed with the gear ring 405, the gear 406 driven by the second motor 409 drives the gear ring 405 in the fixed The inner part of the ring 402 rotates, and further the multiple gears 406 are also driven by the gear ring 405. Since the rack 404 is meshed with the gear 406, when the multiple gears 406 rotate, the multiple racks 404 all move radially on the fixed ring 402 to clamp the plastic tube, so as to avoid a large opening at the cutting position during cutting and change the cutting position, and to protect the two plastic tubes after cutting from falling and being damaged. When cutting, the magnetic ring 403 or the fixed ring 402 can be held, and the magnetic ring 403 can be rotated in the circumferential direction to achieve the effect. The outer side of the magnetic ring 1 401 is rotated to adjust the cutting position in the circumferential direction, and the magnetic ring 1 401 and the magnetic ring 2 403 can be magnetically attracted to increase the resistance during movement and prevent the magnetic ring 2 403 from rotating randomly during cutting to affect the cutting. The radially sliding rack 404 can clamp and fix plastic pipes of different diameters. The laser cutting machine body 202 on the moving frame 201 can cut the marked part of the plastic pipe. After the cutting is completed, the first motor 301 can drive the two slides 302 to move back to each other to wait for grinding.

[0035] Then, after the plastic pipe to be cut is clamped by the two sets of racks 404, the electric push rods 602 on the two mounting plates 601 can be started. After the two electric push rods 602 are extended, the support block 603 is lifted up, and the pressure sensor 604 on the support block 603 also moves accordingly. When the pressure sensor 604 collides with the outer wall of the clamped plastic pipe, the pressure sensor 604 can alarm. At this time, the electric push rod 602 can no longer rise. After the pressure sensor 604 collides with the outer wall of the plastic pipe, further support is provided to the plastic pipe. Since the support plate 608 on the connecting rod 605 of the side wall of the support block 603 is flush with the surface of the pressure sensor 604, when After the pressure sensor 604 contacts the outer wall of the plastic tube, the multiple support plates 608 will also contact the outer wall of the plastic tube. The multiple support plates 608 can be moved equidistantly to the two connecting rods 605, so as to support the two cut plastic tubes. The support points for the plastic tubes are also increased during cutting, which improves the stability during cutting. At the same time, the cut plastic tubes can be prevented from falling directly, and the plastic tubes can be protected. The most important thing is that the support plates 608 and the pressure sensor 604 will move with the movement of the slide plate 302, which means that the plastic tubes can be protected all the time. After the clamping and support are completed, the laser cutting machine body 202 on the mobile frame 201 is started to cut the cutting points of the plastic tubes.

[0036] Finally, when the cutting of the plastic tube clamped by the two sets of racks 404 is completed, the two slide plates 302 can be controlled by the first motor 301 to move in opposite directions. At this time, the two plastic tubes will also move in opposite directions, and a larger space will be generated between the two plastic tubes. However, the two plastic tubes are still clamped by the two sets of racks 404. The electric push rod 508 located on the workbench 1 is further started. The electric push rod 508 moves the moving plate 501 on the moving frame 201 between the two fixed rings 402. When the two grinding discs 507 move to the bottom of the two plastic tubes, the two hydraulic cylinders 50 are started. 3. After the hydraulic cylinder 503 rises, it pushes the grinder 506 to rise. When the two grinding discs 507 move to between the two plastic pipes and ensure that the two grinding discs 507 can cover the cut surface, the movement of the hydraulic cylinder 503 is stopped, and the two slide plates 302 are controlled by the first motor 301 to move relative to each other, so that the cut surfaces of the two plastic pipes are brought into contact with the grinding discs 507. The grinder 506 is started to grind the cut surfaces of the plastic pipes with the two grinding discs 507 to increase the flatness of the cutting. The grinding and cutting debris are discharged from the ash leakage port 306 to the inside of the discharge port 307.
