Description

Technical Field

[0001] The invention relates to the technical field of laser cutting equipment, and in particular to a laser cutting device and method for a steel pad used for adjusting the elevation of a continuous beam. Background Art

[0002] The elevation adjustment of the sling of the upper front beam of the continuous beam generally uses the upper parts of two jacks to support the sling pole beam. The upper part of the sling pole beam is a sling pad, which is connected to the sling with a latch. The height of the jack is adjusted to adjust the elevation of the bottom template. However, the jack is prone to failure after long-term and repeated use, and the top of the jack has a small contact surface with the sling pole beam, which can easily cause the jack to become unstable and stress to be concentrated on a certain part of the sling pole beam. In order to ensure the stability and force balance of the lower part of the sling pad, after the jack adjusts the sling elevation, a special steel pad will be placed under the sling pad. After the steel pad is in place, the jack and the pad are removed. Using steel pads for support eliminates construction risks caused by jack failure, instability, and overturning.

[0003] The existing steel pad is a concave structure and is generally processed by laser cutting. During cutting, a whole steel plate is placed on a workbench, and then the laser cutting machine cuts the steel plate into pieces of steel pads. The existing laser cutting machine uses a support plate to support the steel plate. A triangular support point is set on the top of the support plate. Although the contact area with the steel plate is reduced, there is still a situation in which the laser burns the support point during the laser cutting process, resulting in damage to the support plate. When the triangular points on the top of the support plate are damaged, it will affect the stability of the steel plate placement, and then affect the accuracy of laser cutting of the plate; the burned support plate also needs to be replaced. During the replacement process, the laser cutting equipment needs to stop operating, affecting the efficiency of mass production of steel pads. Summary of the invention

[0033] See also Figure 1 , Figure 2 and Figure 3 The alignment mechanism 5 includes a front pushing assembly 51 installed on the workbench 1 for pushing the steel plate forward for alignment. An electric push rod 52 is installed on the front inner wall of the workbench 1 to drive the front pushing assembly 51 to move forward and push the steel plate to move left for alignment. A tension spring 53 is installed on the workbench 1 to pull the front pushing assembly 51 to return to its original position backward.

[0034] See also Figure 1 , Figure 3 and Figure 4 The left and right limiting mechanisms 3 include a triangular block 31 matched with the triangular groove at the top of the support plate 6, and a left limiting component for blocking and limiting the left side of the steel plate is installed on the triangular block 31. A locking rack 34 is installed on the front side of the triangular block 31, and a right limiting component for positioning the right side of the sample 8 and limiting the telescopic length of the electric push rod 52 under the push of the electric push rod 52 is installed on the locking rack 34; the locking rack 34 is made of high-hardness alloy steel material to ensure that it will not deform during movement.

[0035] See also Figure 3 , Figure 4 and Figure 5 The left limit assembly includes a slide groove opened on the top of the triangular block 31 and a baffle 32 slidably installed on the slide groove. A return spring 33 is fixedly connected between the left side of the baffle 32 and the inner wall of the slide groove. A locking rack 34 is slidably installed on the bottom of the baffle 32 up and down. A lifting component 35 guiding the locking rack 34 to move downward is installed on the front side of the triangular block 31.

[0036] See also Figure 5 and Figure 6The lifting component 35 includes a mounting frame 351 fixedly connected to the front side of the triangular block 31, a guide groove 352 with a left end tilted downward is provided on the front inner wall of the mounting frame 351, a slider 353 slidingly matched with the guide groove 352 is fixedly connected to the rear side of the locking rack 34, a connecting rod 354 is fixedly connected to the top of the locking rack 34, and the connecting rod 354 is slidably connected to the baffle 32 up and down, and the front side of the mounting frame 351 is fixedly connected to the front inner wall of the workbench 1 through an elastic telescopic rod.

[0037] See also Figure 3 , Figure 4 , Figure 5 and Figure 6 Before cutting the steel plate, the template 8 is first placed on the support plate 6 between the left limit assembly and the right limit assembly. The front side of the template 8 is in contact with the front inner wall of the workbench 1, and the right limit assembly is pushed to the left by the electric push rod 52. When the right limit assembly is aligned with the right side of the template 8, the electric push rod 52 pushes the right limit assembly and the template 8 to move to the left together. When the left side of the template 8 conflicts with the right side of the baffle 32, the template 8 will push the baffle 32 to move to the left. Since the triangular block 31 is the same size as the triangular groove at the top of the support plate 6, the range of movement of the baffle 32 to the left is always within the range of the triangular groove, so that the left side of the template 8 is always above the triangular groove, thereby staggering the left side of the template 8 with the triangular support point at the top of the support plate 6, avoiding laser melting of the triangular support point at the top of the support plate 6 during cutting.

[0038] When the template 8 collides with the baffle 32 and pushes the baffle 32 to move to the left, the baffle 32 will drive the connecting rod 354 to move to the left, and the connecting rod 354 will drive the locking rack 34 to move to the left. During the movement of the locking rack 34 to the left, the guide groove 352 is used to guide the slider 353, so that the locking rack 34 moves to the left and downward at the same time, and the locking rack 34 is used to trigger the right limit assembly to position the right side of the template 8.

[0039] See also Figure 3 , Figure 4 , Figure 7 and Figure 8 The right-side limiting assembly includes a movable sleeve 36 slidably mounted on the inner wall of the front side of the workbench 1, and a telescopic sleeve 37 is slidably mounted on the rear side of the movable sleeve 36. A compression spring is fixedly connected between the front end of the telescopic sleeve 37 and the inner wall of the movable sleeve 36. A through groove is opened on the telescopic sleeve 37 for the chain rack 34 to move up and down and left and right. The right end of the chain rack 34 passes through the telescopic sleeve 37 from the through groove, and a locking component 38 is installed inside the telescopic sleeve 37 to lock the telescopic sleeve 37 and the chain rack 34.

[0040] See also Figure 7 and Figure 8The locking component 38 includes an insertion rod 381 slidably installed on the rear side of the telescopic sleeve 37, a return spring 382 is fixedly connected between the front end of the insertion rod 381 and the inner wall of the telescopic sleeve 37, a groove matching the locking rack 34 is provided at the bottom of the insertion rod 381, and a limit block 383 engaging with the locking rack 34 is fixedly connected to the bottom of the front end of the insertion rod 381.

[0041] See also Figures 3 to 8 In the initial state, the locking rack 34 is clamped in the groove at the bottom of the insertion rod 381, and the return spring 2 382 is in a compressed state. The locking rack 34 is used to limit the insertion rod 381 to prevent the insertion rod 381 from extending to the right to the outside of the telescopic sleeve 37 and affecting the left and right movement of the telescopic sleeve 37. At this time, the right end of the telescopic sleeve 37 conflicts with the front side of the frontmost support plate 6.

[0042] When the telescopic end of the electric push rod 52 extends to the left, the electric push rod 1 52 will first push the movable sleeve 36 to move to the left. When the movable sleeve 36 moves to align with the right side of the template 8, the electric push rod 1 52 will drive the template 8 and the movable sleeve 36 to move to the left together. When the left side of the template 8 conflicts with the baffle 32 and pushes the baffle 32 to move to the left, the interlocking rack 34 will move downward and separate from the groove. At this time, the insertion rod 381 will have a tendency to move backward driven by the rebound force of the return spring 2 382. If the right side of the template 8 is just above the triangular groove at the top of the support plate 6, the insertion rod 381 will pop outward under the push of the return spring 2 382, ​​and the insertion rod 381 will drive the limit block 383 to move backward, so that the limit block 383 engages with the interlocking rack 34, thereby limiting the telescopic sleeve 37 from continuing to move to the left, thereby positioning the right side of the template 8.

[0043] If the right side of the sample 8 is just above the triangular support point on the top of the support plate 6, the insertion rod 381 will be blocked by the triangular support point and cannot pop out backwards. The electric push rod 52 can push the movable sleeve 36 to continue to move one end distance to the left until the right side of the sample 8 is offset from the triangular support point. At this time, the insertion rod 381 is no longer blocked by the triangular support point and pops out backwards, so that the limit block 383 is engaged with the interlocking rack 34 and restricts the telescopic sleeve 37, thereby realizing the positioning of the right side of the sample 8.

[0044] See also Figure 1 , Figure 2 , Fig. 9 and Fig.10The front and rear limiting mechanisms 4 include a telescopic lever 41 slidably mounted on the right inner wall of the workbench 1, the telescopic end of the telescopic lever 41 is an L-shaped structure with an inclined bottom, an L-shaped top rod 42 is slidably mounted on the fixed section of the telescopic lever 41, and the vertical section of the L-shaped top rod 42 is located at the front side of the telescopic lever 41, a bolt for locking the telescopic lever 41 and the L-shaped top rod 42 is threadedly mounted on the telescopic lever 41, a scale line is provided on the top of the L-shaped top rod 42, a positioning assembly 43 for locking the telescopic lever 41 and the workbench 1 is installed at the right end of the fixed section of the telescopic lever 41, and a clamping assembly 44 for clamping and fixing the support plate 6 is installed at the front end of the L-shaped top rod 42.

[0045] See also Fig. 9 and Fig.10 The positioning assembly 43 includes a slide seat 431 slidably installed on the top of the workbench 1, the top of the right end of the fixed section of the telescopic gear rod 41 is hinged to the top of the slide seat 431, and a plurality of positioning holes 432 equidistantly distributed on the front side are opened on the right inner wall of the workbench 1. The right end of the fixed section of the telescopic gear rod 41 is fixedly connected with a positioning pin 433 which is plugged into the positioning hole 432. The clamping assembly 44 includes a clamping plate 441 which is rotatably installed on the front side of the vertical section of the L-shaped top rod 42 through a round rod. The distance between the clamping plate 441 and the front side of the vertical section of the L-shaped top rod 42 is equal to the thickness of the support plate 6. The front side of the L-shaped top rod 42 is fixedly connected with a top block 442 located on the left side of the round rod.

[0046] See also Figure 1 , Figure 2 , Fig.11 and Fig.12 The adjusting mechanism 7 comprises a scissor-type telescopic frame 71 which is installed inside the workbench 1 and is symmetrically distributed on the left and right sides. The front end of the scissor-type telescopic frame 71 is fixedly connected to the front inner wall of the workbench 1. A bracket for supporting the scissor-type telescopic frame 71 is fixedly installed inside the workbench 1. The scissor-type telescopic frame 71 is slidably installed on the bracket forward and backward. The scissor-type telescopic frame 71 is composed of a plurality of scissor arms hinged front and back. A mounting seat 72 is fixedly connected to the connecting shaft connecting adjacent scissor arms. The support plate 6 is detachably mounted on the mounting seat 72. An electric push rod 2 73 for pushing the scissor-type telescopic frame 71 to telescope and move is fixedly installed inside the workbench 1. A connecting plate is fixedly connected between the cross axes of the two scissor arms on the rear side. The rear side of the telescopic end of the electric push rod 2 73 is fixedly connected to the middle part of the connecting plate.

[0047] See also Figure 1 , Figure 2 , Fig. 9 , Fig.10 , Fig.11 and Fig.12In the initial state, the clamping plate 441 rotates 270° counterclockwise to the top of the top block 442. When in use, first rotate the telescopic lever 41 upward by a certain angle so that the bottom of the telescopic end of the telescopic lever 41 is flush with the ground of the template 8. At this time, the positioning pin 433 is separated from the positioning hole 432 and the vertical section of the L-shaped top rod 42 is completely moved to the top of the support plate 6. Then the telescopic lever 41 is slid forward to contact the rear side of the template 8. At the same time, the electric push rod 2 73 pushes the scissor-type telescopic frame 71 to extend backward, and the scissor-type telescopic frame 71 is used to drive the support plate 6 to move backward, so that only the number of support plates 6 greater than or equal to three and an odd number is retained at the bottom of the template 8, and the rear side of the template 8 and the support plate 6 below it are in a state of front-to-back staggered. It should be noted that the spacing between adjacent support plates 6 is greater than the width of the central groove of the template 8.

[0048] Then, the telescopic lever 41 is rotated downward to re-insert the positioning pin 433 and the positioning hole 432 together, and the telescopic lever 41 is used to position the rear side of the template 8. Then, the bolts fixing the L-shaped top rod 42 are loosened and the L-shaped top rod 42 is slid forward, so that the distance A from the front side of the vertical section of the L-shaped top rod 42 to the front side of the telescopic section of the telescopic lever 41 is equal to half of the width B of the center groove of the template 8. Then, the electric push rod 2 73 drives the scissor-type telescopic frame 71 to drive the support plate 6 to move backward, so that the support plate 6 near the rear side of the template 8 is The support plate 6 is in conflict with the vertical section of the L-shaped top rod 42. Since the template 8 is a left-right symmetrical structure and the support plates 6 are equidistantly distributed, the middle support plate 6 among the odd-numbered support plates 6 at the bottom of the template 8 will coincide with the mid-vertical plane of the template 8. Since the distance B / 2 between the front and rear side edges of the central groove of the template 8 and the middle support plate 6 is smaller than the spacing between two adjacent support plates 6, the front and rear side edges of the central groove of the template 8 will not coincide with the support plates 6, thereby avoiding the support plates 6 from being burned during the cutting process.

[0049] When the vertical section of the L-shaped top rod 42 collides with the support plate 6, the clamping plate 441 is rotated 270° clockwise so that the clamping plate 441 and the vertical section of the L-shaped top rod 42 can limit the support plate 6 together to prevent the support plate 6 from moving again, thereby improving the accuracy of the positioning of the support plate 6 when supporting the steel plate later.

[0050] See also Figure 1 , Figure 2 and Figure 3 The front pushing assembly 51 includes a movable horizontal frame 511 slidably installed on the top of the workbench 1. The front side of the movable horizontal frame 511 is fixedly connected to a plurality of elastic telescopic rods 512 equidistantly distributed on the left and right sides. The front sides of the plurality of elastic telescopic rods 512 are commonly fixedly connected to a pushing plate 513. Tension springs 53 are fixedly connected between the left and right ends of the rear side of the movable horizontal frame 511 and the top of the workbench 1.

[0051] See also Figure 1 , Figure 2 and Figure 3 The left side of the telescopic section of the electric push rod 52 is fixedly connected with an L-shaped push plate 521, the bottom of the horizontal section of the L-shaped push plate 521 is flush with the top of the support plate 6, the vertical section of the L-shaped push plate 521 faces downward and is located on the right side of the movable sleeve 36, and the left and right ends of the movable cross frame 511 are fixedly connected with a pull rope 522. The top of the workbench 1 is rotatably installed with three fixed pulleys 523 arranged on the left and right. The middle fixed pulley 523 is located just in front of the fixed section of the electric push rod 52, and the other two fixed pulleys 523 are located at two corner positions on the front side of the workbench 1. The right pull rope 522 passes through the rightmost fixed pulley 523 and is fixedly connected to the front side of the L-shaped push plate 521. The left pull rope 522 passes through the two fixed pulleys 523 on the left and is fixedly connected to the front side of the L-shaped push plate 521. The purpose of using the pull rope 522 is to facilitate operation. Compared with the fully automatic driving technology, the use of the pull rope 522 is more convenient.

[0052] See also Figures 1 to 12 During positioning, the electric push rod 52 pushes the L-shaped push plate 521 to move to the left together, and the horizontal section of the L-shaped push plate 521 pushes the sample 8 to move to the left. The vertical end of the L-shaped push plate 521 can push the movable sleeve 36 to move to the left, so that the middle part of the movable sleeve 36 and the right side surface of the sample 8 remain flush with each other, which is convenient for positioning the right side of the sample 8. After positioning is completed, the L-shaped push plate 521 is driven to move to the right by the electric push rod 52 to release the clamping of the sample 8, and then the telescopic end of the telescopic gear rod 41 is pushed to move to the right, so that the telescopic end of the telescopic gear rod 41 no longer blocks the sample 8, and then the sample 8 is removed from the support plate 6.

[0053] Afterwards, the steel plate that is the same width as the sample 8 and needs to be cut is placed on the support plate 6, with the front end of the steel plate located between the baffle 32 and the L-shaped push plate 521, and the rear end located in front of the pushing plate 513. The L-shaped push plate 521 is pushed to the left by the electric push rod 1 52, so that the L-shaped push plate 521 pushes the steel plate to move to the left for alignment. When the L-shaped push plate 521 moves to the left, the pull rope 522 pulls the movable cross frame 511 forward, and the movable cross frame 511 pushes the pushing plate 513 forward through the elastic telescopic rod 2 512, so that the pushing plate 513 pushes the steel plate forward, so that the front side of the steel plate is in conflict with the front inner wall of the workbench 1, and the steel plate is aligned front and back.

[0054] When the L-shaped push plate 521 pushes the right side of the steel plate to align with the middle of the telescopic sleeve 37, the vertical section of the L-shaped push plate 521 conflicts with the movable sleeve 36. Since the telescopic sleeve 37 is locked with the interlocking rack 34 and the insertion rod 381 is plugged into the triangular groove at the top of the support plate 6, the L-shaped push plate 521 cannot continue to move to the left. At this time, the steel plate is just clamped between the baffle 32 and the L-shaped push plate 521, and the steel plate is aligned left and right. In this way, when the steel plate is subsequently laser cut, the laser can avoid burning the support plate 6, thereby increasing the service life of the support plate 6. After the alignment is completed, the electric push rod 52 drives the L-shaped push plate 52 to move left. Plate 521 moves to the right. During the movement of the L-shaped push plate 521 to the right, the pull rope 522 relaxes the forward pulling force on the movable cross frame 511. At this time, the rebound force of the tension spring 53 is used to push the movable cross frame 511 to move backward. The movable cross frame 511 drives the elastic telescopic rod 2 512 and the pushing plate 513 to move backward, so that the pushing plate 513 and the L-shaped push plate 521 release the clamping of the steel plate to avoid affecting the subsequent cutting of the steel plate. Finally, the steel plate is cut from front to back by the laser cutting mechanism 2 according to the trajectory required for cutting the steel pad. The first steel pad cut out completely coincides with the position when the template 8 is positioned.

[0055] The present invention also provides a cutting method of a steel pad laser cutting device for adjusting the elevation of a continuous beam, which specifically includes the following steps: S1: placing a template 8 on a support plate 6 between a left-side limiting assembly and a right-side limiting assembly, with the front side of the template 8 in conflict with the front inner wall of the workbench 1.

[0056] S2: The template 8 is clamped and positioned through the cooperation of the left and right limit mechanisms 3, the front and rear limit mechanisms 4, the alignment mechanism 5, and the adjustment mechanism 7.

[0057] S3: The front and rear limiting mechanisms 4 and the alignment mechanism 5 release the clamping of the template 8, and then the template 8 is removed and the steel plate is placed on the support plate 6.

[0058] S4: The steel plate is pushed and aligned by the alignment mechanism 5.

[0059] S5: After the alignment is completed, the alignment mechanism 5 releases the pushing on the steel plate, and finally the laser cutting mechanism 2 performs laser cutting on the steel plate.
