Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of laser cutting equipment, in particular to a steel pad laser cutting equipment for continuous beam elevation adjustment and a method thereof. BACKGROUND

[0002] The elevation adjustment of the front upper cross beam sling of the continuous beam generally uses two jacks to press against the sling pole beam from the top, the upper part of the sling pole beam is a sling pad seat, the pad seat is connected with the sling by using a latch, and the height of the jack is adjusted to realize the elevation adjustment of the bottom formwork. However, the jack is prone to failure after long-term repeated use, and the contact area between the top of the jack and the sling pole beam is small, which is easy to cause the instability of the jack and the stress concentration in a certain part of the sling pole beam. In order to ensure the stability and stress balance of the lower part of the sling pad seat, a special steel pad is placed under the sling pad seat after the sling elevation is adjusted by the jack, and the jack and the pad beam are removed after the steel pad is placed in place. The use of the steel pad for supporting eliminates the construction risks caused by the failure, instability and overturning of the jack.

[0003] The existing steel pad is of a concave structure and is generally processed by laser cutting. During cutting, a whole steel plate is placed on the workbench, and then the laser cutting machine cuts the steel plate into a plurality of steel pads. The existing laser cutting machine uses a support plate to support the steel plate, and the top of the support plate is provided with a triangular support point. Although the contact area with the steel plate is reduced, the support point is still melted by laser during the laser cutting process, resulting in damage to the support plate. When the triangular point at the top of the support plate is damaged, the stability of the steel plate is affected, and the precision of the plate laser cutting is affected. The melted support plate also needs to be replaced, and the laser cutting equipment needs to be stopped during the replacement process, which affects the efficiency of the batch production of the steel pad.

[0041] Please refer to Figure 3 to Figure 8 In the initial state, the interlocking rack 34 is clamped in the groove at the bottom of the insertion rod 381, the reset spring 382 is in the compressed state, the insertion rod 381 is limited by the interlocking rack 34, so as to avoid the insertion rod 381 extending to the outside of the telescopic sleeve 37 to the right and affecting the left and right movement of the telescopic sleeve 37, and at this time, the right end of the telescopic sleeve 37 abuts against the front side of the frontmost supporting plate 6.

[0042] When the telescopic end of the electric push rod 52 is extended to the left, the electric push rod 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 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 abuts against 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 under the driving force of the reset spring 382, if the right side of the template 8 is just above the triangular groove on the top of the supporting plate 6, the insertion rod 381 will be pushed out by the reset spring 382, the insertion rod 381 drives the limiting block 383 to move backward, so that the limiting block 383 is engaged with the interlocking rack 34, thereby limiting the telescopic sleeve 37 from continuing to move to the left and positioning the right side of the template 8.

[0043] If the right side of the template 8 is just above the triangular supporting point on the top of the supporting plate 6, at this time, the insertion rod 381 will be blocked by the triangular supporting point and cannot be pushed out backward, the electric push rod 52 can push the movable sleeve 36 to continue to move to the left by a distance, until the right side of the template 8 is disengaged from the triangular supporting point, at this time, the insertion rod 381 is no longer blocked by the triangular supporting point and is pushed out backward, so that the limiting block 383 is engaged with the interlocking rack 34 and limits the telescopic sleeve 37, thereby positioning the right side of the template 8.

[0044] Please refer to Figure 1 、 Figure 2 、 Figure 9 and Figure 10The front and rear limiting mechanism 4 comprises a telescopic stop rod 41 slidably mounted on the right inner wall of the workbench 1, the telescopic end of the telescopic stop rod 41 is of an L-shaped structure with an inclined bottom, an L-shaped top rod 42 is slidably mounted on the fixed section of the telescopic stop rod 41 and the vertical section of the L-shaped top rod 42 is located on the front side of the telescopic stop rod 41, a bolt is threadedly mounted on the telescopic stop rod 41 to lock the telescopic stop rod 41 and the L-shaped top rod 42, the top of the L-shaped top rod 42 is provided with a scale line, the right end of the fixed section of the telescopic stop rod 41 is provided with a positioning assembly 43 for locking the telescopic stop rod 41 and the workbench 1, and the front end of the L-shaped top rod 42 is provided with a clamping assembly 44 for clamping and fixing the support plate 6.

[0046] Please refer to Figure 1 , Figure 2 , Figure 11 and Figure 12 , the adjusting mechanism 7 comprises scissor-type telescopic frames 71 symmetrically distributed on the left and right sides and mounted in the workbench 1, the front ends of the scissor-type telescopic frames 71 are fixedly connected to the front inner wall of the workbench 1, supports are fixedly mounted in the workbench 1 for supporting the scissor-type telescopic frames 71, the scissor-type telescopic frames 71 are slidably mounted on the supports, the scissor-type telescopic frames 71 are composed of a plurality of scissors arms hingedly connected front to back, mounting seats 72 are fixedly connected to the connecting shafts connecting adjacent scissors arms, the support plate 6 is detachably mounted on the mounting seats 72, and a second electric push rod 73 is fixedly mounted in the workbench 1 for driving the telescopic movement of the scissor-type telescopic frames 71, and a connecting plate is fixedly connected between the intersecting shafts of the last two scissors arms, and the rear side of the telescopic end of the second electric push rod 73 is fixedly connected to the middle part of the connecting plate.

[0047] Please refer to Figure 1 , Figure 2 , Figure 9 , Figure 10 , Figure 11 and Figure 12, the clamping plate 441 is counterclockwise rotated 270° to the top of the top block 442 in the initial state, and in use, the telescopic guide rod 41 is first upward rotated by a certain angle, so that the bottom of the telescopic end of the telescopic guide rod 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 segment of the L-shaped top rod 42 is completely moved above the support plate 6, then the telescopic guide rod 41 is slid forward to abut against the rear side of the template 8, and at the same time, the scissor-type telescopic frame 71 is driven to extend rearward by the electric push rod two 73, the support plate 6 is driven to move rearward by the scissor-type telescopic frame 71, so that the bottom of the template 8 only remains an odd number of support plates 6 which is greater than or equal to three, and the rear side edge of the template 8 and the support plate 6 below it are in a front-rear staggered state. It should be noted that the distance between the adjacent support plates 6 is greater than the width of the central groove of the template 8.

[0052] Please refer to Figure 1 to Figure 12 When positioning, the electric push rod one 52 pushes the L-shaped push plate 521 to move leftward together, the horizontal section of the L-shaped push plate 521 pushes the template 8 to move leftward, and the vertical end of the L-shaped push plate 521 can push the movable sleeve 36 to move leftward, so that the middle part of the movable sleeve 36 and the right side surface of the template 8 remain flush, facilitating positioning of the right side of the template 8, after completing the positioning, the L-shaped push plate 521 is driven by the electric push rod one 52 to move rightward, releasing the clamping of the template 8, and then the telescopic end of the telescopic stop rod 41 is pushed to move rightward, so that the telescopic end of the telescopic stop rod 41 no longer blocks the template 8, and then the template 8 is taken off from the support plate 6.

[0053] Then a steel plate with the same width as the template 8 and needing to be cut is placed on the support plate 6, the front end of the steel plate is located between the baffle 32 and the L-shaped push plate 521, and the rear end is located at the front side of the pushing plate 513, the L-shaped push plate 521 is pushed to move leftward by the electric push rod one 52, so that the L-shaped push plate 521 pushes the steel plate to move leftward for positioning, and when the L-shaped push plate 521 moves leftward, the movable cross frame 511 is pulled to move forward by the pull rope 522, the pushing plate 513 is pushed to move forward by the elastic telescopic rod two 512 through the movable cross frame 511, so that the pushing plate 513 pushes the steel plate to move forward, and the front side of the steel plate abuts against the inner wall of the front side of the workbench 1, for front and rear positioning of the steel plate.

[0054] When the right side of the steel plate is aligned with the middle part of the telescopic sleeve 37 by the L-shaped push plate 521, the vertical section of the L-shaped push plate 521 is in contact with the movable sleeve 36, and the L-shaped push plate 521 cannot continue to move to the left because the telescopic sleeve 37 is locked with the interlocking rack 34 and the plug rod 381 is inserted into the triangular groove at the top of the support plate 6, 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, so that the subsequent laser cutting of the steel plate can avoid melting the support plate 6 by laser, and the service life of the support plate 6 is improved. After the alignment is completed, the electric push rod 1 52 drives the L-shaped push plate 521 to move to the right, and in the process of moving to the right, the pull rope 522 relaxes the forward pulling force of the movable cross frame 511, at this time, the elastic force of the tension spring 53 pushes 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 loosen the clamping of the steel plate, avoiding affecting the subsequent cutting of the steel plate, and finally the laser cutting mechanism 2 cuts the steel plate from front to back according to the required track of cutting the steel pad, and the first piece of steel pad is completely overlapped with the position of the sample plate 8 during positioning.

[0055] The application also provides a cutting method of the continuous beam elevation adjustment steel pad laser cutting equipment, which specifically comprises the following steps: S1: placing the sample plate 8 on the support plate 6 between the left and right limiting assemblies, and the front side of the sample plate 8 is in contact with the inner wall of the front side of the workbench 1.
