Description

Technical Field

[0001] The present invention relates to the field of cutting processing technology, and in particular to a laser cutting device for workpiece processing. Background Art

[0002] Laser cutting uses a focused laser beam to irradiate the workpiece, causing the material at the irradiated area to quickly melt, vaporize or reach the ignition point, and at the same time use auxiliary airflow to blow away the melted or vaporized material to complete the cutting. Laser cutting can focus into a very small light spot, so that the focus reaches a very high power density. The material is quickly heated to the point of vaporization and evaporates to form a hole. As the beam and the material move linearly relative to each other, a slit is formed.

[0015] Beneficial effects of the present invention:

[0016] 1. When in use, place the steel pipe body to be cut on the receiving rollers. At this time, the weight of the steel pipe body is taken up by the two receiving rollers, and then the auxiliary cutting assembly is moved to the set position (the distance between the auxiliary cutting assembly and the laser cutting head is the cutting length). Then, one end of the steel pipe body is pressed against the auxiliary cutting assembly, and the end of the steel pipe body is clamped by the set auxiliary cutting assembly. Then the laser cutting head works. During this process, the two receiving rollers and the auxiliary cutting assembly drive the steel pipe body to rotate and cooperate to perform the cutting operation. When a single cutting operation is completed, the receiving rollers and the auxiliary cutting assembly stop driving the steel pipe body. At this time, the cut part of the steel pipe body is still cut by the auxiliary cutting assembly. The cutting assembly is clamped, and then the auxiliary cutting assembly moves the cut part of the steel pipe body away from the receiving roller, and then the telescopic end of the electric push rod 1 pushes the engaging claw to move downward, and the cut part of the steel pipe body is clamped by the provided engaging claw, and then under the action of the translation mechanism 1, the receiving slider, the electric push rod 1, the engaging claw and the cut part of the steel pipe body are prompted to move toward the direction close to the blanking slot. When the engaging claw and the cut part of the steel pipe body move above the blanking slot, the engaging claw releases the cut part of the steel pipe body, and the cut part of the steel pipe body is further guided for blanking through the provided blanking slot, which is easy to use.

[0017] 2. When in use, the end of the steel pipe body to be cut is pressed against the pneumatic clamping chuck, and then the end of the steel pipe body is clamped by the pneumatic clamping chuck, so as to receive the end of the steel pipe body to avoid displacement of the part of the steel pipe body to be cut when the steel pipe body is cut again, thereby affecting the cutting accuracy. When in use, the two receiving rollers drive the steel pipe body to be cut to rotate, and the drive box also drives the pneumatic clamping chuck to rotate at the same speed to avoid torque between the steel pipe body and the part to be cut during the cutting process, thereby affecting the cutting accuracy.

[0018] 3. In the initial state, the pusher plate is located away from the laser cutting head to avoid affecting the placement of the steel pipe body to be cut. When the steel pipe body to be cut is placed between the two receiving rollers, the electric guide rail drives the electric slider to move, thereby driving the pusher plate and the extension plate to move close to the end of the steel pipe body. During this process, the pusher plate and the extension plate will contact the end of the steel pipe body and push the steel pipe body to move until the other end of the steel pipe body contacts the pneumatic clamping chuck to complete the positioning of the cutting position. In the process of pushing the steel pipe body to move, the pusher plate will drive the mounting plate and the brush layer to move together. After the brush layer contacts the receiving roller, it will wipe and clean the surface of the receiving roller to avoid excessive dust adhering to the surface of the receiving roller, etc., which affects the drive of the steel pipe body. During this process, the vacuum cleaner works to generate airflow. The dust generated by the brush layer during the cleaning process will be sucked away by the adjacent outer exhaust hood and inner exhaust hood, which is easy to use.

An auxiliary cutting component is provided on the workbench 100, and an L-shaped mounting frame 104 is fixed to the upper end surface of the workbench 100. The upper end surface of the L-shaped mounting frame 104 is provided with a sliding groove 105. A receiving slider 106 is slidingly provided in the sliding groove 105, and an electric push rod 107 is fixedly provided on the upper end surface of the receiving slider 106. The end of the telescopic end of the electric push rod 107 is detachably provided with an engaging claw 108, and the engaging claw 108 is a prior art. A blanking groove 109 is provided on one side of the upper end surface of the workbench 100, and a translation mechanism 1 used in conjunction with the receiving slider 106 is provided on the L-shaped mounting frame 104, and a pushing assembly is provided on the workbench 100.

[0034] The specifications and models of the engaging clamping jaws 108 can be replaced. The specific installation method between the electric push rod 107 and the engaging clamping jaws 108 is a prior art and is not limited here.

[0035] When in use, the steel pipe body 600 to be cut is placed on the receiving roller 101. At this time, the weight of the steel pipe body 600 is borne by the two receiving rollers 101, and then the auxiliary cutting assembly is moved to the set position (the distance between the auxiliary cutting assembly and the laser cutting head 103 is the cutting length). Then, one end of the steel pipe body 600 is pressed against the auxiliary cutting assembly, and the end of the steel pipe body 600 is clamped by the set auxiliary cutting assembly. Then the laser cutting head 103 works. During this process, the two receiving rollers 101 and the auxiliary cutting assembly drive the steel pipe body 600 to rotate and cooperate to perform the cutting operation. When a single cutting operation is completed, the receiving rollers 101 and the auxiliary cutting assembly stop driving the steel pipe body 600. At this time, the cut part of the steel pipe body 600 is still clamped by the auxiliary cutting assembly, and then The rear auxiliary cutting assembly moves the cut part of the steel pipe body 600 away from the receiving roller 101, and then the telescopic end of the electric push rod 107 pushes the engaging jaw 108 to move downward, and the cut part of the steel pipe body 600 is clamped by the provided engaging jaw 108, and then under the action of the translation mechanism 1, the receiving slider 106, the electric push rod 107, the engaging jaw 108 and the cut part of the steel pipe body 600 are prompted to move in the direction close to the blanking groove 109. When the engaging jaw 108 and the cut part of the steel pipe body 600 move above the blanking groove 109, the engaging jaw 108 releases the cut part of the steel pipe body 600, and the cut part of the steel pipe body 600 is further guided for blanking through the provided blanking groove 109, which is convenient to use.

[0036] Then the telescopic end of the electric push rod 107 contracts, driving the engaging claw 108 to move upward, and then under the action of the translation mechanism 1, the receiving slider 106, the electric push rod 107, and the engaging claw 108 are prompted to move and reset. In this process, as needed, the auxiliary cutting component, the laser cutting head 103, the two receiving rollers 101 and the pushing component can be cooperated to continue cutting the remaining steel pipe body 600.

[0037] Two limiting sliding grooves are symmetrically provided on the inner wall of the sliding through groove 105 , and a limiting sliding block 110 is slidably provided in each limiting sliding groove. The limiting sliding block 110 is fixed to one side of the receiving sliding block 106 .

[0038] The cooperation between the limit slider 110 and the limit slot is used to limit and guide the translation of the limit slider 110 .

[0039] The first translation mechanism includes an electric push rod 111 fixed to the upper end surface of the L-shaped mounting frame 104 , a connecting block 112 is fixed to the upper end surface of the receiving slider 106 , and the end of the telescopic end of the electric push rod 111 is fixedly connected to the connecting block 112 .

[0040] By setting the second electric push rod 111, when the telescopic end of the second electric push rod 111 is extended, the driving connecting block 112, the receiving slider 106, the first electric push rod 107, and the engaging clamping claw 108 are translated close to the blanking groove 109.

[0041] The auxiliary cutting assembly includes a drive box 200 movably arranged on the upper end surface of the workbench 100, a connecting disk 201 is fixed on one side of the drive box 200, a pneumatic clamping chuck 202 is rotatably arranged on one side of the connecting disk 201, and a translation mechanism 2 is provided on the workbench 100 for use with the drive box 200.

[0042] The driving box 200 , the connecting plate 201 and the pneumatic clamping chuck 202 are all prior art, and the driving box 200 driving the pneumatic clamping chuck 202 to rotate is also prior art.

[0043] When in use, the end of the steel pipe body 600 to be cut is pressed against the pneumatic clamping chuck 202, and then the end of the steel pipe body 600 is clamped by the pneumatic clamping chuck 202, thereby supporting the end of the steel pipe body 600, thereby preventing the part of the steel pipe body 600 that is about to be cut from being displaced when the steel pipe body 600 is cut again, thereby affecting the cutting accuracy.

[0044] During use, the two receiving rollers 101 drive the steel pipe body 600 to be cut to rotate, and the drive box 200 also drives the pneumatic clamping chuck 202 to rotate at the same speed to avoid torque between the steel pipe body 600 and the part to be cut during the cutting process, which affects the cutting accuracy.

[0045] A left side sunken groove 203 is provided on the upper end surface of the workbench 100, and a left side movable seat 204 is slidably arranged in the left side sunken groove 203. A left side screw rod 205 is rotatably arranged on the inner wall of the left side sunken groove 203, and the left side screw rod 205 is threaded through the left side movable seat 204. A working motor 206 used in conjunction with the left side screw rod 205 is provided on one side of the workbench 100, and the drive box 200 is fixed to the upper end surface of the left side movable seat 204.

[0046] By setting up a working motor 206, the left side screw rod 205 can be driven to rotate, thereby driving the left side movable seat 204 to move, thereby driving the drive box 200 to move horizontally for position adjustment and positioning. The movement and positioning of the drive box 200, the connecting disk 201 and the pneumatic clamping chuck 202 are existing technologies.

[0047] A side sliding groove 300 is provided on one side of the vertical mounting frame 102, and a lifting slider 301 is movably arranged in the side sliding groove 300. A vertical screw rod 302 is rotatably arranged in the side sliding groove 300, and the vertical screw rod 302 is threaded through the lifting slider 301. A working motor 2 303 used in conjunction with the vertical screw rod 302 is fixed to the upper end surface of the vertical mounting frame 102, and a connecting arm 304 is fixed to one side of the lifting slider 301, and the laser cutting head 103 is fixed to one side of the connecting arm 304.

[0048] When in use, the second working motor 303 can drive the vertical screw 302 to rotate, thereby driving the lifting slider 301 to move, thereby driving the connecting arm 304 and the laser cutting head 103 to adjust the height position.

[0049] A right side sinking groove 400 is provided on the upper end surface of the workbench 100, and two right side movable seats 401 are symmetrically and movably arranged in the right side sinking groove 400. Two driving seats 402 are fixed on the upper end surface of each right side movable seat 401. Each receiving roller 101 is rotatably set between the corresponding two driving seats 402. A working motor three 403 used in conjunction with the receiving roller 101 is fixed on one side of the driving seat 402, and a translation mechanism three used in conjunction with the two right side movable seats 401 is provided in the right side sinking groove 400.

[0050] When in use, the steel pipe body 600 to be cut is placed between the two receiving rollers 101. When the cutting position of the steel pipe body 600 is determined, the working motor 3 403 drives the corresponding receiving roller 101 to rotate, and the two receiving rollers 101 cooperate to drive the steel pipe body 600 to rotate, causing the steel pipe body 600 to rotate clockwise or counterclockwise, thereby cooperating with the cutting process of the steel pipe body 600.

[0051] By setting up the translation mechanism three, the distance between the two right-side movable seats 401 can be adjusted, thereby adjusting the distance between the two receiving rollers 101, so as to adapt to the use of steel pipe bodies 600 of different diameters. However, although the distance between the two right-side movable seats 401 can be adjusted, it is also fine-tuning, so the applicability of this application solution to steel pipe bodies 600 of different diameters is still limited.

[0052] The translation mechanism three includes two right-side screw rods 404 rotatably arranged in the right-side sinking groove 400, each right-side screw rod 404 is threaded through the two right-side movable seats 401, and a working motor four is provided in the workbench 100 for use with the right-side screw rod 404. A plurality of limiting guide rails 405 for use with the right-side movable seat 401 are fixed to the inner bottom of the right-side sinking groove 400.

[0053] The two right-side movable seats 401 can move horizontally on the limiting guide rail 405. Through the provided working motor 4, the right-side screw rod 404 can be driven to rotate, thereby driving the two right-side movable seats 401 away from or towards each other, thereby driving the two receiving rollers 101 away from or towards each other. This part of the content is the existing technology.

[0054] The pushing assembly includes two electric guide rails 500 fixed to the upper end surface of the workbench 100, and an electric slider 501 is slidably arranged in each electric guide rail 500. The upper end surfaces of the two electric sliders 501 are fixed with the same pushing plate 502, and the lower end surface of the pushing plate 502 is fixed with an extension plate 503. The electric guide rails 500 and the electric slider 501 are both existing technologies.

[0055] In the initial state, the pusher plate 502 is located away from the laser cutting head 103 to avoid affecting the placement of the steel pipe body 600 to be cut. When the steel pipe body 600 to be cut is placed between the two receiving rollers 101, the electric guide rail 500 drives the electric slider 501 to move, thereby driving the pusher plate 502 and the extension plate 503 to move together close to the end of the steel pipe body 600. During this process, the pusher plate 502 and the extension plate 503 will contact the end of the steel pipe body 600, pushing the steel pipe body 600 to move until the other end of the steel pipe body 600 contacts the pneumatic clamping chuck 202, completing the positioning of the cutting position. The determination of the cutting position of the steel pipe body 600 is an existing technology.

[0056] Two connecting seats 504 are symmetrically fixed to the lower end surface of the push plate 502, and the lower end surface of each connecting seat 504 is removably provided with a mounting plate 505, and the lower end surface of the mounting plate 505 is fixed with a brush layer 506. Two outer exhaust hoods 507 and two inner exhaust hoods 508 are symmetrically fixed to the lower end surface of the push plate 502, and one side of the outer exhaust hood 507 and the inner exhaust hood 508 are connected to a branch ventilation pipe 509. A vacuum cleaner 510 is fixed to one side of the push plate 502, and the air inlet end of the vacuum cleaner 510 is connected to the main ventilation pipe 511, and each branch ventilation pipe 509 is connected to the main ventilation pipe 511.

[0057] When in use, an outer exhaust hood 507 and an inner exhaust hood 508 form a group, and the outer exhaust hood 507 and the inner exhaust hood 508 are distributed on both sides of the corresponding brush layer 506.

[0058] When the pusher plate 502 pushes the steel pipe body 600 to move, it will drive the mounting plate 505 and the brush layer 506 to move together. After the brush layer 506 contacts the receiving roller 101, it will wipe and clean the surface of the receiving roller 101 to prevent excessive dust from adhering to the surface of the receiving roller 101, which will affect the drive of the steel pipe body 600. During this process, the vacuum cleaner 510 works to generate air flow. The dust generated by the brush layer 506 during the cleaning process will be sucked away by the adjacent outer exhaust hood 507 and the inner exhaust hood 508, which is convenient to use.

[0059] When the present invention is in use, the steel pipe body 600 to be cut is placed on the receiving roller 101. At this time, the weight of the steel pipe body 600 is borne by the two receiving rollers 101, and then the auxiliary cutting assembly is moved to the set position (the distance between the auxiliary cutting assembly and the laser cutting head 103 is the cutting length). Then, one end of the steel pipe body 600 is pressed against the auxiliary cutting assembly, and the end of the steel pipe body 600 is clamped by the set auxiliary cutting assembly. Then the laser cutting head 103 works. During this process, the two receiving rollers 101 and the auxiliary cutting assembly drive the steel pipe body 600 to rotate and cooperate to perform the cutting operation. When a single cutting operation is completed, the receiving rollers 101 and the auxiliary cutting assembly stop driving the steel pipe body 600. At this time, the cut part of the steel pipe body 600 is still clamped by the auxiliary cutting assembly. Then the auxiliary cutting assembly moves the cut portion of the steel pipe body 600 away from the receiving roller 101, and then the telescopic end of the electric push rod 107 pushes the engaging jaws 108 to move downward, and the cut portion of the steel pipe body 600 is clamped by the provided engaging jaws 108. Then, under the action of the translation mechanism 1, the receiving slider 106, the electric push rod 107, the engaging jaws 108 and the cut portion of the steel pipe body 600 are prompted to move in a direction close to the blanking notch 109. When the engaging jaws 108 and the cut portion of the steel pipe body 600 move above the blanking notch 109, the engaging jaws 108 release the cut portion of the steel pipe body 600, and the cut portion of the steel pipe body 600 is further guided for blanking through the provided blanking notch 109, which is convenient to use.

[0060] Then the telescopic end of the electric push rod 107 contracts, driving the clamping claw 108 to move upward, and then under the action of the translation mechanism 1, the receiving slider 106, the electric push rod 107, and the clamping claw 108 are moved and reset. In this process, the auxiliary cutting component, the laser cutting head 103, the two receiving rollers 101 and the pushing component can be used as needed to cooperate to continue cutting the remaining steel pipe body 600;

[0061] When in use, the end of the steel pipe body 600 to be cut is brought into contact with the pneumatic clamping chuck 202, and then the pneumatic clamping chuck 202 clamps the end of the steel pipe body 600, thereby holding the end of the steel pipe body 600, thereby preventing the portion of the steel pipe body 600 that is about to be cut from being displaced when the steel pipe body 600 is cut again, thereby affecting the cutting accuracy;

[0062] During use, the two receiving rollers 101 drive the steel pipe body 600 to be cut to rotate, and the driving box 200 also drives the pneumatic clamping chuck 202 to rotate at the same speed, thereby preventing the generation of torque between the steel pipe body 600 and the part to be cut during the cutting process, which would affect the cutting accuracy.

[0063] In the initial state, the pusher plate 502 is located away from the laser cutting head 103 to avoid affecting the placement of the steel pipe body 600 to be cut. When the steel pipe body 600 to be cut is placed between the two receiving rollers 101, the electric guide rail 500 drives the electric slider 501 to move, thereby driving the pusher plate 502 and the extension plate 503 to move together close to the end of the steel pipe body 600. During this process, the pusher plate 502 and the extension plate 503 will contact the end of the steel pipe body 600, pushing the steel pipe body 600 to move until the other end of the steel pipe body 600 contacts the pneumatic clamping chuck 202, completing the positioning of the cutting position;

[0064] When the pusher plate 502 pushes the steel pipe body 600 to move, it will drive the mounting plate 505 and the brush layer 506 to move together. After the brush layer 506 contacts the receiving roller 101, it will wipe and clean the surface of the receiving roller 101 to prevent excessive dust from adhering to the surface of the receiving roller 101, which will affect the drive of the steel pipe body 600. During this process, the vacuum cleaner 510 works to generate air flow. The dust generated by the brush layer 506 during the cleaning process will be sucked away by the adjacent outer exhaust hood 507 and the inner exhaust hood 508, which is convenient to use.

[0065] The above disclosure is only a preferred embodiment of the present invention. However, the embodiments of the present invention are not limited thereto. Any changes that can be conceived by those skilled in the art should fall within the scope of protection of the present invention.
