Description

Technical Field

[0001] The present invention relates to the technical field of laser cutting, and in particular to a laser tube cutting machine capable of automatically feeding materials. Background Art

[0002] Laser tube cutting machine is a device that uses laser technology to cut metal tubes. The cutting accuracy of laser tube cutting machine is very high. Since laser cutting is a non-contact process, laser cutting basically does not cause deformation of the tube. Laser tube cutting machine is generally equipped with an automatic feeding system, which can deliver the tubes to the cutting area accurately and quickly.

[0003] The cutting process of the laser tube cutting machine is generally to place a whole long tube in the cutting area, and then cut and cut holes in the tube in sections as the tube is delivered, reciprocated and rotated.

[0004] However, due to the different wall thicknesses of the pipes being cut, the pipes need to be positioned during the cutting process in order to drive the pipes to rotate. If holes need to be opened on the side walls of the pipes during the cutting process, the pipes need to be driven to move back and forth. This requires that a certain degree of clamping force be applied to the pipes when they are positioned. This clamping force generally only positions the pipes through friction and does not affect the mutual movement between the pipes and the positioning structure. This clamping force will have a certain impact on the delivery of the pipes. If the pipes are thinner, the fast delivery speed of the pipes will result in a larger impact force between the pipes and the positioning structure. Therefore, the thinner pipes will be subjected to both positioning and delivery forces during the delivery process, which can easily cause the pipes to bend and deform, affecting their subsequent use. Summary of the invention

DETAILED DESCRIPTION

[0032] The technical solution of the present invention is further described below in conjunction with the accompanying drawings.

[0033] When the existing laser tube cutting machine feeds the tubes, due to the different thickness of the tubes and the need to apply a certain degree of clamping force during the movement of the tubes, if the thinner tubes are delivered too fast, the two sides of the tubes will be affected by the fixing force and the delivery force respectively and will be deformed. In addition, when the existing laser tube cutting machine positions the tubes, the tubes of the same diameter often use the same positioning force, which will cause the thinner tubes to be deformed due to excessive clamping force, while the thicker tubes are heavier and easily cause the tubes to slip.

The plate 107 is in transmission cooperation. After the telescopic end of the electric telescopic rod 105 moves forward to contact with the sliding plate 107, the telescopic end of the electric telescopic rod 105 drives the sliding plate 107 to move forward. When the telescopic end of the electric telescopic rod 105 is retracted and reset, the telescopic end of the electric telescopic rod 105 loses contact with the sliding plate 107. An elastic member is fixed between the sliding plate 107 and the sliding frame 104, wherein the elastic member is a spring. The front side of the sliding frame 104 is slidably connected to a second electromagnetic slider 108 electrically connected to the control panel through an electromagnetic slide rail, and a detection rod 108 is slidably connected to the second electromagnetic slider 108 and is slidably connected to the sliding rod 106. 09, the detection rod 109 performs adaptive measurement on the wall thickness of the pipe fitting, the sliding frame 104 is fixedly connected with a sliding rheostat 110 electrically connected to the first electromagnetic slider 101 through a supporting plate, the sliding rheostat 110 is electrically connected to the control panel, the sliding plate 107 is fixedly connected to the sliding piece of the sliding rheostat 110, when the sliding piece of the sliding rheostat 110 moves forward, its internal resistance decreases, so that the flow of current in the first electromagnetic slider 101 becomes larger, when the sliding piece of the sliding rheostat 110 moves backward, its internal resistance increases, so that the flow of current in the first electromagnetic slider 101 becomes smaller, and a positioning component 3 for positioning the pipe fitting is arranged on the base 1.

[0035] See also Figure 1 , Figure 3 and Figure 5-Figure 7The positioning assembly 3 includes a third electromagnetic slider 301 electrically connected to the control panel, an electromagnetic slide rail is arranged on the right side of the base 1, the third electromagnetic slider 301 is slidably connected to the electromagnetic slide rail of the base 1, the third electromagnetic slider 301 is electrically connected to the sliding rheostat 110, when the slider of the sliding rheostat 110 moves forward, its internal resistance decreases, so that the flow of current in the third electromagnetic slider 301 becomes larger, when the slider of the sliding rheostat 110 moves backward, its internal resistance increases, so that the flow of current in the third electromagnetic slider 301 becomes smaller, the third electromagnetic slider 301 is fixedly connected to a motor 302 electrically connected to the control panel, the third electromagnetic slider 301 is fixedly connected to a rotating ring, and the rotating ring of the third electromagnetic slider 301 is rotatably connected to a rotating disk 303, the sliding The center line of the moving frame 104, the axis of the detection rod 109 and the axis of the rotating disk 303 are all located on the same horizontal plane, which is used to measure the wall thickness of the pipe. The output shaft of the motor 302 and the rotating disk 303 are transmitted through a transmission member, wherein the transmission member is composed of two mutually meshing spur gears, one of which is fixedly connected to the rotating disk 303, and the other is fixedly connected to the output shaft of the motor 302. A gear is rotatably connected to the rotating disk 303, and four racks distributed circumferentially and meshing with the gear are slidably connected to the rotating disk 303. An L-shaped rod 304 is fixedly connected to the rack of the rotating disk 303, and a rotating rod 305 is rotatably connected to the L-shaped rod 304, wherein the rotating rod 305 is flexible, and is used to reduce the friction force on its outer surface during the delivery of the pipe.

[0036] See also Figure 4 , Figure 6 and Figure 7 A first hydraulic telescopic rod 5 is fixedly connected to the front side of the sliding plate 107, and the telescopic end of the first hydraulic telescopic rod 5 is fixedly connected to the sliding frame 104. The elastic force of the elastic member on the sliding plate 107 is greater than the resistance of the telescopic end of the first hydraulic telescopic rod 5 when it moves, and is used to ensure that the telescopic end of the first hydraulic telescopic rod 5 does not shrink when the telescopic end of the first hydraulic telescopic rod 5 is actively pressurized, so that the first hydraulic telescopic rod 5 moves backward as a whole. A rotating shell 501 connected to the first hydraulic telescopic rod 5 is rotatably connected to the rotating disk 303, and a second hydraulic telescopic rod 502 connected to the rotating shell 501 is fixedly connected to the rotating disk 303. The second hydraulic telescopic rod 502 is an arc-shaped telescopic rod, and the axis of the rotation trajectory of the telescopic end of the second hydraulic telescopic rod 502 is aligned with the axis of the rotating disk 303, and the telescopic end of the second hydraulic telescopic rod 502 is fixedly connected to the gear of the rotating disk 303.

[0037] See also Figure 3 and Figure 8A third hydraulic telescopic rod 6 is fixedly connected to the fixed frame 103, and the telescopic end of the third hydraulic telescopic rod 6 is fixedly connected to the sliding frame 104. A fourth hydraulic telescopic rod 601 connected to the third hydraulic telescopic rod 6 is fixedly connected to the middle of the upper side of the base 1, and the telescopic end of the fourth hydraulic telescopic rod 601 is fixedly connected to the first connecting rod 602. The fourth hydraulic telescopic rod 601 is located in the middle of the first connecting rod 602. A plurality of adjusting rods 603 distributed in a linear array are fixedly connected to the first connecting rod 602. The first connecting rod 602 is used to drive the plurality of adjusting rods 603 to move up and down synchronously, thereby adjusting the height position of the support block 604. The lower side of the adjusting rod 603 slides in the base 1, and the upper side of the adjusting rod 603 is fixedly connected to an arc-shaped support block 604, and the support block 604 is used to support the pipe fitting.

[0038] When the operator needs to use the device to perform laser cutting on a pipe fitting, the operator places the pipe fitting on the support block 604 which is distributed in a straight line through the external automatic loading device, and then the operator controls to open the first electromagnetic slide block 101 (the first electromagnetic slide block 101 is initially located at the far left), so that the first electromagnetic slide block 101 pushes the pipe fitting to move to the right (the initial state of the electric telescopic rod 105 is extended, and the electric telescopic rod 105 drives the detection rod 109 to move forward through the sliding plate 107 and the sliding rod 106, and at the same time, the sliding plate 107 drives the sliding frame 104 to move forward through the first hydraulic telescopic rod 5, and the first hydraulic telescopic rod The telescopic end of the first hydraulic telescopic rod 5 is affected by the thrust of the rear sliding plate 107 and the resistance of the front sliding frame 104. The telescopic end of the first hydraulic telescopic rod 5 contracts, and the circumferentially distributed rotating rods 305 are in a circumferentially open state, so that the pipe fitting can pass between the circumferentially distributed rotating rods 305. After the telescopic end of the first hydraulic telescopic rod 5 is reset, the circumferentially distributed rotating rods 305 are in a gathered state, positioning the pipe fitting and giving it a certain degree of slight clamping force). During the movement to the right, the pipe fitting squeezes the inclined surface on the sliding frame 104, causing the sliding frame 104 to move backward, and the pipe wall of the pipe fitting is gradually inserted between the sliding frame 104 and the detection rod 109.

[0039] During the process of the pipe fitting moving along the inclined surface of the sliding frame 104, the control panel controls the telescopic end of the electric telescopic rod 105 to retract and reset, and the elastic part of the sliding plate 107 pops out and drives it to gradually reset. Since the pipe wall is inserted between the sliding frame 104 and the detection rod 109, the relative position of the detection rod 109 and the sliding frame 104 cannot be completely reset to the initial state, resulting in the sliding rod 106 being unable to drive the elastic part of the sliding plate 107 to completely reset during the reset process, until the telescopic end of the electric telescopic rod 105 moves to the position aligned with the sliding plate 107. After losing contact, the detection rod 109 moves to be close to the inner wall of the pipe, and the elastic part of the sliding frame 104 drives it to be close to the outer wall of the pipe. Due to the influence of the thickness of the pipe wall, the elastic part of the sliding plate 107 cannot be completely reset, and the elastic force of the elastic part on the sliding plate 107 is greater than the resistance of the sliding piece on the sliding rheostat 110 when moving. Therefore, the sliding plate 107 and the sliding frame 104 jointly drive the telescopic end of the first hydraulic telescopic rod 5 to retract. At the same time, the position of the sliding plate 107 changes and synchronously drives the sliding piece of the sliding rheostat 110 to move.

[0040] When the slider on the sliding rheostat 110 moves, the greater the distance between the sliding frame 104 and the detection rod 109, the greater the distance the slider of the sliding rheostat 110 moves forward, thereby making the resistance of the sliding rheostat 110 smaller, and the current flow rate flowing in the first electromagnetic slider 101 larger, so that the first electromagnetic slider 101 drives the pipe to advance to the right faster, and the current flow rate in the third electromagnetic slider 301 is larger, and the movement speed of the third electromagnetic slider 301 will also become faster, thereby changing the feeding speed of the pipe. The feeding speed of the pipe is adaptively adjusted according to the thickness of the pipe wall to avoid the pipe being pushed and deformed due to the thin pipe and the feeding speed is too fast, and at the same time prevent the pipe from being too thick and causing insufficient feeding force, thereby affecting the cutting efficiency.

[0041] When the telescopic end of the first hydraulic telescopic rod 5 is retracted, the first hydraulic telescopic rod 5 squeezes the internal liquid into the rotating shell 501 through the conduit, and then the liquid in the rotating shell 501 is transported to the second hydraulic telescopic rod 502, so that the telescopic end of the second hydraulic telescopic rod 502 is retracted and drives the gear of the rotating disk 303 to rotate, the gear of the rotating disk 303 rotates and synchronously drives the circumferentially distributed racks to move, the rack of the rotating disk 303 drives the adjacent L-shaped rod 304 to move, and the L-shaped rod 304 drives the adjacent rotating rod 305 to move, and the slight clamping force on the pipe is relaxed (in the process of the pipe passing through the rotating rod 305, the telescopic end of the first hydraulic telescopic rod 5 is in a retracted state, so the rotating rod 305 does not position the pipe, and when the sliding plate 107 gradually begins to recover, the pipe is not positioned. After the pipe is in position, the telescopic end of the first hydraulic telescopic rod 5 gradually extends out, so the rotating rod 305 positions and clamps the pipe). The telescopic amount of the telescopic end of the first hydraulic telescopic rod 5 is different for different pipe wall thicknesses, so that the first hydraulic telescopic rod 5 drives the adjacent rotating rods 305 to move by the rotating housing 501, the second hydraulic telescopic rod 502, the gear of the rotating disk 303, the rack of the rotating disk 303 and the adjacent L-shaped rods 304 to change the distance. The thinner the pipe, the looser the clamping of the circumferentially distributed rotating rods 305 on the pipe, so as to avoid the pipe being damaged due to excessive clamping force due to thin pipe walls, and at the same time prevent the pipe from being damaged due to insufficient clamping force when the pipe is thick, so as to prevent the pipe from moving downward under the influence of gravity, thereby causing the positioning and clamping of the pipe to fail and slip during the cutting process, thereby affecting the cutting effect.

[0042] During the movement of the sliding frame 104, the sliding frame 104 drives the telescopic end of the third hydraulic telescopic rod 6 to move. The larger the diameter of the outer wall of the pipe fitting, the farther the telescopic end of the third hydraulic telescopic rod 6 moves to the right, and the longer the telescopic end of the third hydraulic telescopic rod 6 contracts. As a result, the telescopic end of the fourth hydraulic telescopic rod 601 contracts a longer distance, and the first connecting rod 602 drives the adjusting rod 603 distributed in a straight line thereon to move downward a longer distance, so the height of the support block 604 is lowered to accommodate the placement of pipe fittings of different diameters.

[0043] When the pipe is fixed, the operator turns on the second electromagnetic slider 108 through the control panel, and the second electromagnetic slider 108 drives the detection rod 109 to move rightward until it loses contact with the pipe. Then the operator turns on the third electromagnetic slider 301 through the control panel, and the third electromagnetic slider 301 drives the rotating disk 303 to move left and right through the rotating ring, and the rotating disk 303 drives the rotating rod 305 to move through the L-shaped rod 304. The circumferentially distributed rotating rods 305 and the limit rods of the first electromagnetic slider 101 synchronously drive the pipe to move left and right. When the pipe moves to the right until its cutting part is located at the lower side of the laser cutter 102, the operator turns on the laser cutter 102 through the control panel, moves the laser cutter 102 up and down to adjust to the required cutting height, and then starts cutting the pipe.

[0044] During the process of cutting the pipe, the operator turns on the motor 302 through the control panel, and the motor 302 drives the rotating disk 303 to rotate through the transmission member. The rotating disk 303 drives the pipe to rotate through the L-shaped rod 304 and the rotating rod 305 to adjust the cutting position.

[0045] After a small section of the pipe is cut off, the operator collects the cut part and then repeats the above cutting steps to cut the pipe. After the operator has finished using the device, the operator controls the first electromagnetic slider 101, the electrically controlled telescopic rod 105, the second electromagnetic slider 108 and the third electromagnetic slider 301 to reset through the control panel, and turns off the first electromagnetic slider 101, the laser cutter 102, the electrically controlled telescopic rod 105, the second electromagnetic slider 108, the sliding rheostat 110 and the third electromagnetic slider 301 through the control panel. Finally, the device is cleaned to facilitate cutting the next pipe.

[0046] After the existing laser tube cutting machine cuts the tube, the cut finished tube and the waste generated during cutting holes fall off and are collected together at the same time, resulting in the need to screen the tube and the waste later. When the waste falls onto the collected tube, it is easy to scratch the surface of the tube, thereby affecting the smoothness of the surface of the tube.

[0047] Example 2: Based on Example 1, please refer to Figure 1 and Fig. 9 , also includes a collecting frame 7, the collecting frame 7 is fixedly connected to the right side of the base 1, and a first guide portion 701 and a second guide portion 702 are arranged in the collecting frame 7, the first guide portion 701 and the second guide portion 702 are both flexible, the first guide portion 701 gradually tilts downward from left to right, and is used to guide the pipe fitting to the second guide portion 702, the inclined surface of the second guide portion 702 gradually tilts downward from right to left, and the second guide portion 702 is used to guide and buffer the pipe fitting, so that the pipe fitting moves to the left along the second guide portion 702 and enters the collecting frame 7.

[0048] See also Fig. 9 and Fig.10 A separation plate 8 is fixedly connected to the right portion of the upper side of the base 1 , and a plurality of separation holes 801 distributed in a linear array are arranged on the separation plate 8 . The separation holes 801 are used to separate and collect the cut small pieces of waste. A collection chamber 802 is arranged near the separation plate 8 on the base 1 .

[0049] See also Fig. 9 and Fig.10A fifth hydraulic telescopic rod 9 is fixedly connected to the fixed frame 103, and the telescopic end of the fifth hydraulic telescopic rod 9 is fixedly connected to the sliding frame 104. A sixth hydraulic telescopic rod 901 connected to the fifth hydraulic telescopic rod 9 is fixedly connected to the position of the base 1 near the separation plate 8, and a second connecting rod 902 is fixedly connected to the telescopic end of the sixth hydraulic telescopic rod 901. A plurality of blocking plates 903 distributed in a linear array and slidably connected to the separation plate 8 are fixedly connected to the second connecting rod 902. The number of the blocking plates 903 is the same as the number of the separation holes 801. The blocking plates 903 are matched with the adjacent separation holes 801 for blocking, and the movement of the blocking plates 903 is used to adjust the opening size of the adjacent separation holes 801.

[0050] After a section of the pipe is cut off, the cut small section of the pipe (the cut small section of the pipe is referred to as the finished pipe in the following text) falls onto the separation plate 8. During the cutting process, various holes will be cut on the finished pipe. The waste generated by the cutting holes will fall into the collection chamber 802 through the separation holes 801, and the finished pipe will fall along the separation plate 8 and the first guide part 701 to the second guide part 702, and then the finished pipe will be collected in the collection frame 7.

[0051] During the movement of the sliding frame 104, the larger the diameter of the pipe, the longer the distance that the sliding frame 104 drives the telescopic end of the fifth hydraulic telescopic rod 9 to move backward, and the fifth hydraulic telescopic rod 9 injects its internal hydraulic oil into the sixth hydraulic telescopic rod 901 through the conduit. The telescopic end of the sixth hydraulic telescopic rod 901 drives a number of blocking plates 903 to move through the second connecting rod 902, and the smaller the amount of blocking of adjacent separation holes 801 by the blocking plates 903. Conversely, the smaller the diameter of the pipe, the larger the amount of blocking of adjacent separation holes 801 by the blocking plates 903. The aperture of the separation hole 801 is adjusted to prevent the finished pipe from being too small to leak into the collection chamber 802, and at the same time prevent the waste cut off from being too large when the finished product is too large, thereby causing the separation hole 801 to be stuck by the waste, affecting the separation effect.

[0052] When an existing laser tube cutting machine drills holes in a tube, it moves and rotates the tube to make holes of various shapes. However, since laser cutting generates moving temperature, the cut edge of the metal tube will be heated and melted. The molten metal liquid solidifies again after cooling, resulting in the waste after cutting the hole unable to fall off in time, which in turn makes the finished tube unusable.

[0053] Example 3: Based on Example 2, please refer to Figure 2 and Fig.11, further comprising a slide 10, the slide 10 is slidably connected to the third electromagnetic slider 301, an elastic member is fixedly connected between the slide 10 and the base 1, wherein the elastic member is a compression spring, an impact rod 1001 is slidably connected to the slide 10, a slope is provided at the rear end of the impact rod 1001, and the slope is pressed and matched with the hole of the pipe fitting, during the rotation of the pipe fitting, the hole of the pipe fitting presses the slope of the impact rod 1001, so that the impact rod 1001 moves forward, and the impact rod 1001 and the slide An elastic member is fixed between the frames 10, wherein the elastic member is a tension spring. A first limiting portion 1002 is provided on the slide 10, and four second limiting portions 1003 which are evenly distributed circumferentially and are squeezed and matched with the first limiting portion 1002 are provided on the rotating disk 303. The second limiting portions 1003 and the first limiting portions 1002 are both wedge-shaped, and the contact surface between the second limiting portions 1003 and the first limiting portions 1002 is an inclined side, which is used to squeeze the first limiting portion 1002 to move forward.

[0054] In the process of the rotating disk 303 driving the pipe to rotate (in the initial state, the four second limiting portions 1003 on the rotating disk 303 are evenly distributed in the circumferential direction, and the four second limiting portions 1003 are respectively aligned with the corresponding cutting hole positions, so that the first limiting portion 1002 is aligned with the cutting hole on the front side of the pipe), when it is necessary to open circumferentially distributed holes on the pipe, the rotating disk 303 drives the four second limiting portions 1003 thereon to rotate. When a second limiting portion 1003 rotates to contact with the first limiting portion 1002, the second limiting portion 1003 gradually squeezes the first limiting portion 1002 to move the slide 10 forward, and the elastic member of the slide 10 gradually contracts. When the second limiting portion 1003 rotates to lose contact with the first limiting portion 1002, due to the fact that a second limiting portion 1003 is in contact with the first limiting portion 1002 at this moment, 1003 rotates to the position of the first limit part 1002, so the position of the cut hole on the pipe fitting is also rotated to be aligned with the first limit part 1002, and the elastic part of the slide 10 drives it to reset, and the slide 10 drives the impact rod 1001 on it to impact the hole cut on the pipe fitting to avoid the edge of the waste on it being affected by the high temperature generated by laser cutting after the hole is cut, resulting in melting of the cutting edge, making it impossible for the waste to be separated from the finished pipe fitting after cutting, thereby making the finished pipe fitting unusable, thereby affecting the cutting quality. After the impact rod 1001 impacts the hole cut on the pipe fitting, the rotating disk 303 drives the pipe fitting to rotate, and the pipe fitting squeezes the inclined surface on the impact rod 1001, so that the elastic part of the impact rod 1001 is stretched, and the impact rod 1001 is separated from the hole cut on the pipe fitting.

[0055] The above is only a preferred embodiment of the present invention. It should be pointed out that for ordinary technicians in this technical field, several improvements and modifications can be made without departing from the principle of the present invention. These improvements and modifications should also be regarded as the scope of protection of the present invention.
