Description

Technical Field

[0001] The invention relates to the technical field of automatic pipe cutting machines, and more particularly to a fully automatic loading double-chuck laser pipe cutting machine. Background Art

[0002] Laser tube cutting machine is an efficient and precise tube processing equipment, which is widely used in metal processing, automobile manufacturing, aerospace, construction engineering and other fields. In the actual production process, the feeding method of the tube directly affects the production efficiency and processing accuracy. The traditional feeding method usually relies on manual or semi-automatic feeding racks, which have problems such as low feeding efficiency, high labor intensity, uneven placement of tubes, easy stacking or misalignment of tubes, etc., which in turn affects the cutting accuracy and increases the scrap rate. When some automatic or semi-automatic feeding racks need to realize automatic feeding of tubes of different sizes, the feeding racks need to manually adjust multiple positions. Since they are all manually adjusted by a single person, the adjustment accuracy and effect are difficult to guarantee. There is a risk of multiple adjustments and misoperation, which seriously wastes time and affects production progress. It is also easy to make errors and affect production stability.

[0003] Furthermore, the pipe cutting machines in the prior art usually adopt a single chuck structure or the front chuck is moved by a cylinder, which leads to some problems: low cutting accuracy, the cylinder is easy to break, thus affecting the processing efficiency, and the single chuck structure cannot effectively cut the tailings of the pipe, resulting in waste of the pipe.

DETAILED DESCRIPTION

[0062] The present invention will now be described in further detail with reference to the accompanying drawings. These drawings are simplified schematic diagrams, which only illustrate the basic structure of the present invention in a schematic manner, and therefore only show the components related to the present invention.

[0063] Fully automatic loading double chuck laser tube cutting machine, please participate Figure 1 As shown, it includes: a main machine 02 and an automatic feeder 01. The automatic feeder 01 is mainly used to transfer a single pipe 00 and transmit it to the main machine 02; the main machine 02 is mainly used to cut the long pipe into the required length. Figure 1 The automatic loader 01 is connected to the end of the host machine 02.

[0064] See also Figure 2-3 As shown, the automatic feeding machine 01 includes: a material rack 100, a material stretching assembly 200, a material pressing assembly 300 and a material blocking assembly 400.

[0065] Continue reading Figure 2-3As shown, the rack 100 has a ground frame 130. Considering that the rack 100 is used to place the pipes 00, if the pipes are metal pipes, after a certain amount of pipes 00 are stacked on the rack 100, the overall weight is relatively large. Therefore, the ground frame 130 is preferably placed on the ground and made of metal material;

[0066] The ground frame 130 mainly plays a supporting role, and its shape is not limited, and can also be set as follows: Figure 2 Shape shown.

[0067] The material rack 100 is formed with a material waiting area 101, and a plurality of material plates 110 are installed on the material rack 100 and are placed vertically and parallel to each other; specifically, the material waiting area 101 is formed on the ground rack 130, and a plurality of material plates 110 are installed on the ground rack 130 and are placed vertically and parallel to each other, and the material waiting area 101 and the material plates 110 are distributed in the X direction; Figure 2 As shown, in the present embodiment, 7 material plates 110 are provided, and spaces are left between adjacent material plates 110; the number of material plates 110 is set according to needs. If the length of the pipe 00 to be cut is relatively short, the number of material plates 110 can be reduced. If the length of the pipe 00 to be cut is relatively long, the number of material plates 110 can be adaptively increased.

[0068] like Fig. 20 As shown, a material trough 120 is provided on the plurality of material plates 110, and the material trough 120 runs through the front and rear surfaces of the material plates 110, and the material trough 120 has an inclined transmission section 121 and a limiting section 122, and the inclined transmission section 121 is higher than the limiting section 122;

[0069] During loading, the pipe 00 is transported from the waiting area 101 to the inclined transmission section 121. Depending on the length of the inclined transmission section 121, multiple pipes 00 can be arranged in the inclined transmission section 121, and then a single pipe 00 falls into the limiting section 122 under the action of its own gravity in the inclined transmission section 121. The pipe 00 waits in the limiting section 122 to be transmitted to the main machine 02.

[0070] The tube 00 is sent from the material waiting area 101 to the material tank 120 through the stretch material assembly 200; Figure 2-3 As shown, the material assembly 200 acts on the material waiting area 101 , and the material assembly 200 includes: a material bandage 210 , a belt winding wheel 220 , a winding wheel 230 and a material bandage motor 240 .

[0071] The belt winding wheel 220 is arranged close to the feed port 123 of the material trough 120, and is correspondingly located at the front of the material plate 110; the winding wheel 230 can be installed on the material plate 110, or can be installed on the ground frame 130, and the winding wheel 230 is located below the belt winding wheel 220;

[0072] During installation, the first end of the bandage 210 is fixed to the rack 100 and is located higher than the belt winding wheel 220. After the bandage 210 passes around the belt winding wheel 220, the second end of the bandage 210 is connected to the winding wheel 230.

[0073] The tube 00 is placed between the beginning of the bandage 210 and the belt winding wheel 220 , and the tube 00 is supported on the bandage 210 .

[0074] The bandage motor 240 drives the winding wheel 230 to rotate forward to wind up the bandage tape 210, so that the position of the tube placed on the bandage tape 210 rises and enters the material trough 120; specifically, since the winding wheel 220 is close to the feed port 123 of the material trough 120, when winding, the rotation direction of the winding wheel 220 and the movement direction of the bandage tape 210 are both to feed the tube 00 into the feed port 123. After the tube 00 enters the feed port 123, it moves in the inclined transmission section 121 by gravity.

[0075] The material bandage components 200 are arranged in multiple groups along the arrangement direction of the material plate 110. The number of material bandage components 200 can be set according to the length of the tube 00 that the equipment needs to cut. In this embodiment, four groups of material bandage components 200 are arranged, and the four groups of material bandage components 200 provide strong support for the tube 00. The position of the winding wheel 230 is lower than the position of the winding wheel 220. During the winding process of the bandage tape 210, the tube is fed into the material slot 120 by the movement of the bandage tape 210.

[0076] Since there are multiple groups of stretching assemblies 200 , the winding wheels 230 in each group of stretching assemblies 200 may be controlled and operated by a stretching motor 240 , or the winding wheels 230 of multiple groups of stretching assemblies 200 may be controlled and operated by the same stretching motor 240 .

[0077] like Fig.11 and Fig.12 As shown, in this embodiment, the winding wheels 230 of the four groups of stretch material assemblies 200 are controlled to rotate by the same stretch material motor 240, which can realize the synchronous rotation of the winding wheels 230 and the synchronous winding of the bandage belt 210, ensuring that the tubes 00 rise in parallel, and preventing the tubes 00 from rising non-parallel due to asynchrony, such as the front end of the tube 00 is high and the rear end is low, etc., ensuring that the tubes 00 can be correctly fed into the feed port 123 of the multiple material plates 110.

[0078] In this embodiment, a first guide rod 250 is horizontally arranged on the multiple material plates 110, and the winding wheel 230 is fixed on the first guide rod 250; the stretching motor 240 is installed on the ground frame 130, and a sprocket is installed on the first guide rod 250. A sprocket is also installed on the stretching motor 240, and the two sprockets are connected by a chain, so that the stretching motor 240 drives the first guide rod 250 to rotate, and finally the winding wheel 230 rotates.

[0079] Optionally, the sprocket and chain mentioned above can be replaced by a transmission wheel and a belt.

[0080] Furthermore, the stretching motor 240 is a motor that can rotate forward and reverse.

[0081] After the pipe 00 is fed into the material trough 120 , in order to ensure that only one pipe 00 falls into the limiting section 122 each time, a material pressing assembly 300 and a material blocking assembly 400 are provided.

[0082] The material pressing assembly 300 can be installed on the material plate 110 or the ground frame 130, as long as it can be used in conjunction with the material trough 120; Figure 4-5 and Fig. 9 As shown, the pressing assembly 300 is installed on the material plate 110. Specifically, the pressing assembly 300 includes: a slide plate 310, a pressing plate 330 and a pressing plate cylinder 340; the slide plate 310 is driven by a slide plate motor 320, and the slide plate motor 320 drives the slide plate 310 to move in the width direction of the inclined transmission section 121, so that the pipes are transmitted in a single row in the inclined transmission section 121; the pressing plate 330 is driven by the pressing plate cylinder 340 to press the pipes in the inclined transmission section 121;

[0083] Specifically, the material plate 110 is provided with a first slide rail 111, the slide plate 310 is installed on the first slide rail 111, the pressing plate cylinder 340 is installed on the slide plate 310, and the pressing plate 330 is provided at the output end of the pressing plate cylinder 340, and the moving directions of the slide plate 310 and the pressing plate 330 are parallel.

[0084] like Fig.21 As shown, the pressing assembly 300 is installed on the material plate 110. Fig.21 The back side of the center plate 110 is therefore shown with a dotted line.

[0085] Fig.21 The fixed width of the middle material trough 120 is H, so the material trough 120 can allow pipes 00 with a diameter ≤H to pass through; in this embodiment, the diameter of the pipe 00 is D, D<H, so multiple pipes 00 are on the inclined transmission section 121, and the pressure plate 330 moves in the K2 direction to press the pipes 00 on the inclined transmission section 121.

[0086] Since the width H of the trough 120 is fixed, the device can automatically load and transport pipes 00 of various sizes with diameters less than H. In the production process, the diameter D of a batch of pipes that may need to be cut may be less than half of H. Then, during transportation, two pipes 00 may be stacked together in the width direction of the trough 120, that is, two rows of pipes 00 will be transported on the trough 120 at the same time. Fig.21There is a row of pipes 00 in the middle, and another row is stacked in the direction of K1 to form two rows of pipes. This will make it inconvenient for the subsequent single pipe 00 to fall into the limiting section 122. Therefore, the slide plate 310 plays a role in adjusting the width of the material trough 120.

[0087] The slide motor 320 drives the slide 310 to move in the direction K2 to reduce the width of the material passing through the trough 120 so that only one row of pipes can be transported in the trough 120 .

[0088] like Figure 5 As shown, the pressing plate cylinder 340 drives the pressing plate 330 to move, and the moving directions of the pressing plate 330 and the slide plate 310 are the same. The pressing plate 330 presses on the pipe 00 and presses the pipe 00 on the inclined transmission section 121.

[0089] Furthermore, the pressing plate 330 moves downward and presses on the tube 00. In order to prevent the tube 00 from being bent, a support plate 350 is provided on the material plate 110 corresponding to the pressing plate 330. The support plate 350 is parallel to the inclined transmission section 121. In the length direction of the tube, the tube is supported by the inclined transmission section 121 and the support plate 350 at the same time. The pressing plate 330 moves toward the support plate 350 to press the tube, and at the same time, the tube is pressed against the inclined transmission section 121.

[0090] Furthermore, the material blocking assembly 400 can be installed on the base frame 130 or on the material plate 110. In this embodiment, the material blocking assembly 400 is placed on the material plate 110. Figure 7 , Figure 8 and Fig.10 As shown, the material blocking assembly 400 includes: a baffle 410 and a baffle cylinder 420 . The baffle cylinder 420 drives the baffle 410 to move to a blocking position so that the pipes in the inclined transmission section 121 cannot fall into the limiting section 122 .

[0091] Continue as Fig.10 and Fig.21 As shown, the material blocking assembly 400 is installed on the front side of the material plate 110, and the material blocking assembly 400 is close to the lower side of the material trough 120, while the material pressing assembly 300 is close to the upper side of the material trough 120; Fig.21 In this case, the baffle 410 is in the blocking position, which blocks the pipe 00 from falling into the limiting section 122. If the baffle 410 moves in the direction of K2 driven by the baffle cylinder 420, one of the pipes that is not pressed by the pressing plate 330 falls into the limiting section 122 under the action of its own gravity.

[0092] like Fig.21As shown, the blocking position of the baffle 410 is separated from the pressing position of the pressing plate 330 by a distance of a pipe diameter D, so that a pipe 001 is kept at the lower end of the inclined transmission section 121 and is not pressed against the inclined transmission section 121; therefore, the baffle 410 moves in the direction of K2 under the drive of the baffle cylinder 420, and the pipe 001 can fall into the limiting section 122 under the action of its own gravity;

[0093] When the pipe 001 falls, the baffle 410 moves in the direction of K1 under the drive of the baffle cylinder 420 and returns to the blocking position. Then, the pressing plate 330 moves in the direction of K1 under the drive of the pressing plate cylinder 340 and no longer presses on the pipe. The pipe in the inclined transmission section 121 moves tiltedly under the action of gravity and moves until the pipe 002 is blocked by the baffle 410; then the pressing plate 330 moves in the direction of K2 under the drive of the pressing plate cylinder 340 and presses on the pipe again, so that the pipe is pressed on the inclined transmission section 121. At this time, the pipe 002 is kept from being pressed. When the pipe in the limit section 122 is transmitted to the main machine 02 for cutting, at an appropriate time, the baffle 410 moves in the direction of K2 under the drive of the baffle cylinder 420, and the pipe 002 can fall into the limit section 122 under the action of its own gravity; in this cycle, automatic loading of a single pipe is carried out.

[0094] Since different batches of pipes have different diameters, or pipes of different diameters need to be cut according to demand, the blocking position of the above-mentioned baffle plate 410 and the pressing position of the pressing plate 330 are separated by a distance of the pipe diameter D. Here, the distance of the pipe diameter D needs to be adjusted, so the baffle assembly 400 is designed to be movable on the material plate 110.

[0095] Continue as Figure 7 , 8 , 10 and Fig.21 As shown, the material plate 110 is provided with a second slide rail 112, the second slide rail 112 is parallel to the inclined transmission section 121, and the material blocking assembly 400 is installed on the second slide rail 112 through a second slide plate 430;

[0096] The second slide plate 430 is provided with a third slide rail 431, and the baffle plate 410 is installed on the third slide rail 431 and moves in the width direction of the inclined transmission section 121. The blocking assembly 400 is driven by the third driving assembly 440 to move along the second slide rail 112, and then the distance between the blocking position of the baffle plate 410 and the pressing position of the pressing plate 330 is adjusted to adapt to pipes of different diameters, ensuring that one pipe is not pressed each time, so as to facilitate the subsequent falling of the unpressed pipe into the limiting section 122.

[0097] Furthermore, in this embodiment, seven material plates 110 are provided, and at least two of the material plates 110 are provided with a material pressing assembly 300 and a material blocking assembly 400; it is worth noting that on one material plate 110, both the material pressing assembly 300 and the material blocking assembly 400 are provided, and the two are used in combination.

[0098] Optionally, the material pressing assembly 300 and the material blocking assembly 400 may be disposed on all seven material plates 110 , or may be selected at intervals, such as disposing the material pressing assembly 300 and the material blocking assembly 400 on the second, fourth, or sixth material plates 110 .

[0099] Furthermore, the slides 310 on the plurality of press components 300 can be driven by a slide motor 320 to move on the first slide rail 111, or the slides 310 on the plurality of press components 300 can be driven by a slide motor 320 to move simultaneously. Figure 2 As shown, a second guide rod 360 is provided on the multiple material plates 110, and the slide motor 320 is connected to the second guide rod 360 and drives the second guide rod 360 to rotate. The slides 310 of the multiple groups of pressing assemblies 300 are respectively connected to the second guide rod 360 through optical axes and couplings, and the rotation of the second guide rod 360 is switched to the linear movement of the slide 310 along the first slide rail 111, so that the multiple groups of pressing assemblies 300 can operate synchronously.

[0100] Similarly, the multiple groups of material blocking assemblies 400 can be driven along the second slide rail 112 by a driving member respectively, or the multiple groups of material blocking assemblies 400 can be driven to move along the second slide rail 112 by the same third driving assembly 440 .

[0101] Specifically, the third driving assembly 440 includes: a third guide rod 441 horizontally arranged on the plurality of material plates 110, a third transmission gear 442 installed on the third guide rod 441, and a third motor group 443 driving the third guide rod 441 to rotate;

[0102] The second slide plate 430 is provided with a rack 432 parallel to the second slide rail 112, and the rack 432 is meshed with the third transmission gear 442; the material blocking assembly 400 slides along the second slide rail 112 to adjust the distance between the blocking position of the baffle plate 410 and the pressing position of the pressing plate 330 in the length direction of the inclined transmission section 121, that is, according to the different diameters of the pipe, the distance between the blocking position of the pressing plate 330 and the pressing position of the pressing plate is adjusted.

[0103] Furthermore, the automatic loader 01 also includes: a follower component 900.

[0104] like Figure 4 and Figure 6As shown, the follower assembly 900 is located below the limiting section 122; the follower assembly 900 includes: a first driving member 910, a fourth slide rail 920 installed on the material plate 110 and located below the limiting section 122, and a roller 930 that can move up and down along the fourth slide rail 920. After the pipe falls into the limiting section 122, it is supported by the limiting section 122 and the roller 930 at the same time, which provides stable support for the pipe and ensures cutting accuracy.

[0105] After a single pipe slides to the bottom of the limiting section 122, it is supported by the follower assembly 900 to ensure cutting accuracy. There are 4 groups of follower assemblies 900. The roller 930 has an arc-shaped supporting surface, and the roller 930 contacts the surface of the pipe; the roller 930 can rotate on its own. After the pipe falls into the limiting section 122, when it needs to be transmitted to the main machine 02, the roller 930 is driven by the driving member to move upward along the fourth slide rail 920, so that the pipe leaves the bottom of the limiting section 122. During the transmission of the pipe to the main machine 02, the roller 930 rotates on its own to assist the transmission of the pipe.

[0106] Furthermore, the roller 930 is driven by a driving member to move up and down along the fourth slide rail 920. On the plurality of material plates 110, all of the material plates 110 may be installed with follower assemblies 900, or some of the material plates 110 may be installed with follower assemblies. In this embodiment, there are 4 sets of follower assemblies 900.

[0107] A fourth guide rod 940 is arranged between the multiple material plates 110, and the fourth guide rod 940 is driven to rotate by the first driving component 910; the roller 930 is installed on the fourth slide rail 920 through the sliding frame 931, the fourth guide rod 940 is provided with a transmission gear, and the sliding frame 931 is provided with a rack, and the transmission gear and the rack are meshed. When the fourth guide rod 940 rotates, it drives the transmission gear to rotate, and then the sliding frame 931 moves along the fourth slide rail 920; the first driving component 910 is a forward and reverse motor.

[0108] Furthermore, if Figure 1 , Figure 13-19 As shown, the host 02 includes: a machine platform 500, a front card assembly 600, a rear card assembly 700 and a cutting assembly 800.

[0109] The machine 500 can be a cabinet-type machine, a box-type machine, etc. A Y slide rail 510 is arranged on the panel of the machine 500. The Y slide rail 510 is in the same direction as the transmission direction or length direction of the pipe 00. The front card assembly 600 and the rear card assembly 700 are both assembled on the Y slide rail 510 and can move along the Y slide rail 510. The rear card assembly 700 transmits the pipe to the front card assembly 600, and the cutting assembly 800 is used to cut the pipe.

[0110] The 13 and Fig.15As shown, the front card assembly 600 includes: a front card chuck 610, a front card clamping claw 620 installed on the front card chuck 610, and a front card rotating motor 630 that drives the front card chuck 610 to rotate; the entire front card assembly 600 is driven by a front card driving motor 640 to move along the Y slide rail 510;

[0111] like Fig.13 and Fig.14 As shown, the rear card assembly 700 includes: a rear card chuck 710, a rear card clamping claw 720 installed on the rear card chuck 710, and a rear card rotating motor 730 that drives the rear card chuck 710 to rotate; the entire rear card assembly 700 is driven by a rear card driving motor 740 to move along the Y slide rail 510.

[0112] Specifically, the tube 00 is transferred to the host 02 and passes through the front card chuck 610 and the rear card chuck 710, and the tube 00 can be grasped by the front card clamp 620 and the rear card clamp 720; Fig.14 and Fig.15 As shown, the front clamping jaws 620 and the rear clamping jaws 720 are respectively provided with a plurality of them, and the pipe 00 passes through the center of the front clamping chuck 610 and the rear clamping chuck 710 and is clamped by the front clamping jaws 620 and the rear clamping jaws 720;

[0113] The front clamping jaw 620 and the rear clamping jaw 720 may be commonly used pneumatic clamps or mechanical clamps.

[0114] After the automatic loader 01 has fed the pipe into place, the pipe will fall into the feeder 03, and the feeder 03 will feed the pipe to the main machine 02; the pipe is clamped by the rear clamping claw 720 on the rear clamping chuck 710 on the rear clamping assembly 700, and the rear clamping drive motor 740 drives the rear clamping assembly 700 and the pipe to move along the Y slide rail 510 to achieve movement in the Y-axis direction. After approaching the front clamping assembly 600, the rear clamping claw 720 opens, and the rear clamping assembly 700 retreats to a position close to the feeder 03. The rear clamping assembly 700 moves repeatedly to achieve the effect of feeding the pipe to the front clamping assembly 600. During this process, the front clamping assembly 600 does not move along the Y slide rail 111.

[0115] When the pipe is cut by the cutting assembly 800, the front clamping jaw 620 and the rear clamping jaw 720 can clamp the pipe at the same time to achieve stable and high-precision cutting.

[0116] During the cutting process, the tube 00 rotates, so the front chuck 610 is driven to rotate by the front rotation motor 630 and the rear chuck 710 is driven to rotate by the rear rotation motor 730. The front chuck 610 and the rear chuck 710 rotate synchronously and drive the tube to rotate, and the cutting assembly 800 cuts the tube.

[0117] When the pipe has been cut into multiple sections and the remaining tailings are to be cut, the front card drive motor 640 on the front card assembly 600 is enabled to process the tailings, and the rear card chuck 710 on the rear card assembly 700 releases the pipe and resets it to its original position, that is, the position close to the feeder 03; the front card clamp 620 on the front card assembly 600 will clamp the pipe, and the front card drive motor 640 on the front card assembly 600 drives the front card assembly 600 to move along the Y slide rail 510 close to the cutting assembly 800 to cut the tailings; extremely short tailing cutting is achieved, greatly reducing the waste of tailings.

[0118] Here, both the front card assembly 600 and the rear card assembly 700 adopt servo control, which improves the operating stability of the equipment.

[0119] Furthermore, the cutting assembly 800 is arranged close to the front card assembly 600, and the cutting assembly 800 is installed as a whole on the X slide rail of the machine table 500. The cutting assembly 800 includes: a Z module 810, a rotating motor 820 installed on the Z module 810, and a cutting head 830 connected to the output shaft of the rotating motor 820;

[0120] The X-slide rail and the Y-slide rail 510 are both mounted on the machine platform 500 , and the X-slide rail and the Y-slide rail 510 are perpendicular to each other. The entire cutting assembly 800 is driven by an X-axis motor to move along the X-slide rail.

[0121] During cutting, the cutting assembly 800 is driven by the X-axis motor to move to the cutting position, and the cutting head 830 performs cutting, and the pipe rotates during the cutting process; after the cutting is completed, the cutting assembly 800 is driven by the X-axis motor to move away from the cutting position;

[0122] The rotary motor 820 can drive the cutting head 830 to rotate, and can achieve 45-degree cutting, or can achieve cutting at other angles as required.

[0123] The cutting head 830 may be a laser cutting head, which is commonly used in laser cutting machines and belongs to the prior art, and will not be described in detail here.

[0124] Furthermore, if Fig.16 and Fig.18 As shown, the feeder 03 includes: two groups of symmetrically arranged conveying wheels 031, wherein the first group of conveying wheels 031 is connected to a feeding drive cylinder 032, and the feeding drive cylinder 032 drives the first group of conveying wheels 031 to move toward the second group of conveying wheels 031 to clamp the pipe; the second group of conveying wheels 031 is connected to a feeding drive motor 033, and the feeding drive motor 033 drives the second group of conveying wheels 031 to rotate to transfer the pipe to the rear clamping assembly 700.

[0125] After the single-rod pipe falls into the limiting section 122, it is then pulled up by the follower assembly 900, and the first set of transmission wheels 031 moves toward the second set of transmission wheels 031 to clamp the pipe, and then the second set of transmission wheels 031 turns to the rear clamp assembly 700 to transfer the pipe;

[0126] Optionally, it can be changed so that both sets of transmission wheels 031 are connected to the feeding drive cylinder 032, and the two sets of transmission wheels 031 can rotate synchronously.

[0127] In addition, the present invention should also be equipped with control systems, sensors and other components in the fully automatic loading and double-chuck laser tube cutting machine to cooperate with complete automated loading and cutting. Control systems, sensors and other components are commonly used technologies in automated equipment and will not be elaborated on in detail here.

[0128] The fully automatic loading double-chuck laser tube cutting machine of the present invention can realize automatic loading, feeding and cutting, has precise cutting, and can realize extremely short tail material cutting, thus saving resources and effectively improving production efficiency.
