Description

Technical Field

[0001] The invention relates to the field of laser cutting, and in particular to a laser cutting machine for plate processing. Background Art

[0002] Laser cutting uses a focused high-power density laser beam to irradiate the workpiece, causing the irradiated material to quickly melt, vaporize, ablate or reach the ignition point, and at the same time uses a high-speed airflow coaxial with the beam to blow away the molten material, thereby achieving the purpose of cutting the workpiece. Laser cutting replaces the traditional mechanical knife with an invisible beam, and has the characteristics of high precision, fast cutting, no restrictions on cutting patterns, automatic typesetting to save materials, smooth incisions, and low processing costs. The mechanical part of the laser cutter head has no contact with the workpiece and will not scratch the workpiece surface during operation.

[0032] In order to enable those skilled in the art to better understand the technical solution of the present invention, Figure 1-11 , the present invention is further introduced in detail.

[0033] In each embodiment of the present invention, for the convenience of description and understanding, the length direction of the support frame 1 is referred to as the length direction, the direction perpendicular to the length direction on the horizontal plane (that is, the width direction of the support frame 1) is referred to as the width direction, and the gravity direction is referred to as the vertical direction, that is, the length direction, the width direction and the vertical direction constitute a three-dimensional rectangular coordinate system.

[0034] An embodiment of the present invention provides a laser cutting machine for plate processing, including a base, on which a support frame 1 and a laser cutting body 2 are installed, a plurality of support plates 3 are arranged at intervals along the length direction on the support frame 1, and also includes a driving mechanism 4 and a locking mechanism 5. The driving mechanism 4 is used to push the support frame 1 to reciprocate in the vertical direction; the locking mechanism 5 is arranged on the support frame 1, and the locking mechanism 5 locks the support plate 3 based on the downward movement of the support frame 1, and the locking mechanism 5 unlocks the support plate 3 based on the upward movement of the support frame 1.

[0035] Specifically, the base and the support frame 1 are both arranged horizontally, and the laser cutting body 2 is generally a vertically arranged laser emitting mechanism, and the head end of the laser cutting body 2 is facing the support frame 1. When the plate needs to be laser cut, manual or automatic equipment places the plate to be cut horizontally on the support frame 1, and multiple support plates 3 on the support frame 1 support the plate under the plate. At this time, the plate to be cut is arranged horizontally, and then the laser cutting body 2 emits a laser to cut the plate. When the cutting laser cuts the metal plate, the cutting laser will also contact the support plate 3 under the plate. Long-term use can easily cause serious wear of the support plate 3 under the plate, and the support plate 3 needs to be replaced regularly. Among them, the existing support plate 3 is usually installed on the support frame 1 by bolt locking. When replacement is required, the staff needs to remove the bolts one by one to complete the replacement of the support plate 3.

[0036] Obviously, when bolts are used to fix the support plate 3, although the firmness of the support plate 3 during installation can be improved, when the support plate 3 is replaced, the staff needs to remove the fixing bolts one by one, and after the support plate 3 is replaced, the bolts need to be installed one by one, resulting in a decrease in the replacement efficiency of the support plate 3, affecting the laser cutting efficiency of the plate.

[0037] In order to solve the above problems, in this embodiment, a driving mechanism 4 is installed on the laser cutting body 2, and the driving end of the driving mechanism 4 is connected to the support frame 1. The driving mechanism 4 drives the support frame 1 to move along the vertical direction with the support plate 3. The driving mechanism 4 can select multiple hydraulic telescopic rods, and a locking mechanism 5 is also installed on the support frame 1. The locking mechanism 5 is used to lock the support plate 3, that is, to fix the support plate 3 on the support plate 3. When the support plate 3 needs to be replaced, the driving mechanism 4 drives the support frame 1 to move upward with the support plate 3 in the vertical direction. As the support frame 1 moves upward, the locking mechanism 5 releases the fixation of the support plate 3, making it convenient for the staff to remove the support plate 3 that needs to be replaced. After completing the replacement of the support plate 3, the driving mechanism 4 pulls the support frame 1 and moves the support plate 3 downward in the vertical direction. As the support frame 1 moves downward, the locking mechanism 5 fixes the support plate 3 again to complete the replacement of the support plate 3. At this time, the staff does not need to use bolts to fix the support plates 3 one by one, thereby improving the replacement efficiency of the support plates 3 and avoiding the situation where the processing efficiency of the plates is reduced due to the inefficiency of replacing the support plates 3.

[0038] Preferably, in this embodiment, the support frame 1 is in the shape of a rectangular frame, and a plurality of placement grooves 11 are provided on both sides of the support frame 1 along the length direction, and the plurality of placement grooves 11 correspond one-to-one to the plurality of support plates 3, that is, one end of the support plate 3 is used to be placed in one placement groove 11, and the two ends correspond to two placement grooves 11, and a plurality of adjustment grooves 12 are also provided on the support frame 1, and the plurality of adjustment grooves 12 correspond one-to-one to the plurality of placement grooves 11, wherein the locking mechanism 5 includes two transmission rods 51, and the two transmission rods 51 are respectively arranged on both sides of the support frame 1, For any one side, the transmission rod 51 passes through all the placement grooves 11 and adjustment grooves 12 on that side, and a plurality of fixed pressure blocks 52 are fixedly installed on the transmission rod 51. A clamping groove 53 is provided on the side of the fixed pressure block 52 close to the support plate 3. In addition, adjustment gears 54 are provided in the plurality of adjustment grooves 12, and the plurality of adjustment gears 54 are fixedly connected to the transmission rod 51. An adjustment rack 55 is also provided in the adjustment groove 12, and the adjustment rack 55 is meshed with the adjustment gear 54 one by one. One end of the adjustment rack 55 passes through the support frame 1 and is fixedly connected to the base.

[0039] Specifically, in the present embodiment, the support plate 3 includes a support portion 31 located in the middle and connecting portions 32 located on both sides, wherein the support portion 31 is formed integrally by a plurality of triangular irons, which is used to support the workpiece to be laser cut, and the connecting portions 32 are located on both sides of the support portion 31 for connecting with the support frame 1, and the support frame 1 is provided with placement grooves 11 on both sides along the length direction in a one-to-one correspondence, that is, a placement groove 11 is provided on one side, and another relative placement groove 11 is provided on the other side, and the two relative placement grooves 11 are adapted to a support plate 3, and the two relative placement grooves 11 are used to carry the corresponding connecting portions 32 on both sides of the support plate 3, and in the initial state, the fixed pressure block 52 limits the connection portion 32 through the clamping groove 53 to achieve the fixation of the support plate 3, that is, locking.

[0040] The steps for replacing the support plate 3 on the support frame 1 are as follows:

[0041] First, the driving mechanism 4 starts to extend, and the driving mechanism 4 drives the support frame 1 to move upward in the vertical direction. The support frame 1 moves synchronously with the support plate 3. As the support frame 1 moves upward, the support frame 1 gradually moves relative to the adjusting rack 55. The adjusting gear 54 in the support frame 1 meshes with the adjusting rack 55. The adjusting gear 54 drives the transmission rod 51 to rotate. When the transmission rod 51 rotates, it rotates synchronously with the fixed pressure block 52, so that the fixed pressure block 52 gradually moves away from the connecting portion 32 of the support plate 3 and enters a vertical state. The support plate 3 loses the restriction of the fixed pressure block 52, and the support plate 3 is unlocked.

[0042] Then, the staff lifts the support plate 3 to be replaced upwards, and the support plate 3 leaves the placement slot 11. Then, the staff inserts the new support plate 3 into the two opposite placement slots 11 on the support frame 1.

[0043] Finally, the driving mechanism 4 starts to contract, and the driving mechanism 4 drives the support frame 1 to move downward in the vertical direction. The support frame 1 moves synchronously with the support plate 3. As the support frame 1 moves downward, the adjusting gear 54 in the support frame 1 meshes with the adjusting rack 55. The adjusting gear 54 rotates under the action of the adjusting rack 55, and the adjusting gear 54 drives the transmission rod 51 to rotate. When the transmission rod 51 rotates, it rotates synchronously with the fixed pressing block 52, so that the fixed pressing block 52 gradually approaches the connecting portion 32 of the support plate 3. The clamping groove 53 wraps around the connecting portion 32 of the support plate 3, and as the fixed pressure block 52 rotates, the fixed pressure block 52 completely presses the support plate 3 into the placement groove 11. Since the placement groove 11 is adapted to the fixed pressure block 52, when the fixed pressure block 52 is completely inserted into the placement groove 11, the placement groove 11 limits the movement of the fixed pressure block 52 in the length and width directions. In this regard, the support plate 3 restricted by the fixed pressure block 52 also loses its movement in the length and width directions. At this time, the support plate 3 is fixed, and the replacement process of the support plate 3 is completed.

[0044] Preferably, an elastic member 6 is further provided at the bottom end of the placement groove 11 , and the elastic member 6 is used to lift the support plate 3 out of the placement groove 11 .

[0045] Specifically, the elastic member 6 can be selectively a lifting spring or a lifting spring. When the support plate 3 is fully inserted into the placement groove 11 under the action of the fixed pressure block 52, the connecting portion 32 of the support plate 3 squeezes the elastic member 6, causing the elastic member 6 to undergo elastic deformation, accumulating elastic potential energy to enhance the stability of the support plate 3. When the fixed pressure block 52 leaves the support plate 3, the fixed pressure block 52 releases the restriction on the support plate 3. At this time, the elastic member 6 releases the accumulated elastic potential energy, and the elastic member 6 lifts the support plate 3 upward, making it convenient for the staff to take the support plate 3 and replace it.

[0046] It should also be noted that, in the present embodiment, in order to facilitate the installation of the support plate 3, the size of the placement groove 11 on the support frame 1 is larger than the size of the connecting portion 32 of the support plate 3. Thus, when the connecting portion 32 of the support plate 3 is inserted into the placement groove 11 on the support frame 1, the support plate 3 is prone to shaking. At this time, a fixed pressure block 52 adapted to the placement groove 11 is provided, and a clamping groove 53 adapted to the connecting portion 32 is provided on the fixed pressure block 52. When the clamping groove 53 wraps the connecting portion 32 of the support plate 3, the clamping groove 53 limits the shaking of the support plate 3. At this time, the fixed pressure block 52 is also inserted into the placement groove 11. The placement groove 11 limits the shaking of the fixed pressure block 52, thereby avoiding the shaking of the support plate 3 in the placement groove 11, thereby ensuring the stability of the support plate 3 when supporting the plate.

[0047] Obviously, in this embodiment, when the locking mechanism 5 is locked or unlocked, all the support plates 3 will be locked or unlocked. However, when replacing the support plates 3, it is not necessarily necessary to replace all the support plates 3. It may be necessary to replace only a part of them or even only a few support plates 3. However, when replacing a small number of support plates 3, the locking mechanism 5 will release the lock on all the support plates 3.

[0048] In order to solve the above problem, in the present embodiment, the adjusting rack 55 is divided into a toothed portion 551 and a fixed portion 552 from top to bottom. The fixed portion 552 is fixedly mounted on the supporting frame 1. The toothed portion 551 and the fixed portion 552 are rotatably connected. A twisting block 7 is fixedly mounted on one end of the toothed portion 551 away from the fixed portion 552. The twisting block 7 is used to rotate the toothed portion 551 so that the toothed portion 551 is misaligned with the adjusting gear 54.

[0049] Specifically, in the initial state, the adjusting gear 54 is meshed with the toothed portion 551 of the adjusting rack 55. When the selected support plate 3 needs to be replaced, the twisting block 7 corresponding to the support plate 3 that does not need to be replaced is manually twisted, and the twisting block 7 rotates synchronously with the toothed portion 551 of the adjusting rack 55. The toothed portion 551 of the adjusting rack 55 is staggered with the adjusting gear 54 (that is, as the adjusting gear 54 moves upward, the toothed portion 551 of the adjusting rack 55 does not mesh). The driving mechanism 4 begins to extend, and the driving mechanism 4 drives the support frame 1 to move upward in the vertical direction. The support frame 1 moves synchronously with the support plate 3. As the support frame 1 moves upward, the support frame 1 gradually moves relative to the adjusting rack 55. However, since the toothed portion 551 of the adjusting rack 55 rotates, the support frame 1 is The adjusting gear 54 cannot adjust the rack 55 to engage, and the adjusting gear 54 cannot drive the transmission rod 51 to rotate. At this time, the fixed pressure block 52 corresponding to the support plate 3 that does not need to be replaced always maintains the locked state of the support plate 3, while the corresponding fixed pressure block 52 on the support plate 3 that needs to be replaced releases the lock of the support plate 3. At this time, the fixed pressure block 52 vertically supports the equipment, which is convenient for the staff to find the support plate 3 to be replaced. After that, the staff will replace the unlocked support plate 3 to complete the replacement operation of the selected support plate 3. Therefore, when replacing the support plate 3, it is only necessary to unlock the corresponding fixed pressure block 52 (the corresponding fixed pressure block 52 here refers to the fixed pressure block 52 of the support plate 3 that needs to be replaced), which reduces the wear of the remaining fixed pressure blocks 52 and thus reduces the maintenance cost of the equipment.

[0050] It should also be noted that when the plate being cut is thin, as the laser cuts the plate, the plate is likely to cut off the support plate 3 below, and in severe cases, even a section of the middle of the support plate 3 may be cut off. Under the action of gravity, the cut support plate 3 is separated from the main body of the support plate 3 and falls to the bottom. At this time, the plate above the fallen support plate 3 will also lose support. If the plate is small in size, it is also easy to separate from the rest of the plates and fall to the bottom of the support plate 3, affecting the subsequent removal.

[0051] In order to solve the above problem, in another embodiment of the present invention, the fixed pressure block 52 includes an inner push section 521 and a connecting section 522, the connecting section 522 is fixedly connected to the transmission rod 51, and a recessed groove 523 is provided at the end of the connecting section 522 away from the transmission rod 51, the inner push section 521 is slidably installed in the recessed groove 523, and the inner push section 521 and the recessed groove 523 are connected by an inner push spring 524, wherein the clamping groove 53 on the fixed pressure block 52 is inclined at one end away from the support plate 3, and a maintaining block 56 is also provided on the transmission rod 51, and a maintaining cylinder 58 is sleeved on the outer side of the maintaining block 56, the maintaining cylinder 58 is fixedly installed on the transmission rod 51, the maintaining block 56 is slidably installed in the maintaining cylinder 58, and the maintaining block 56 and the transmission rod 51 are connected by a maintaining spring 57.

[0052] Specifically, the placement groove 11 below the maintenance block 56 is arc-shaped. In the initial state, that is, when the support plate 3 is in the locked state, the end of the maintenance block 56 abuts against the arc-shaped groove wall of the placement groove 11. At this time, the maintenance spring 57 connected to the maintenance block 56 is in a compressed state, and the maintenance spring 57 accumulates elastic potential energy.

[0053] When the fixed pressure block 52 locks the support plate 3, as the fixed pressure block 52 gradually approaches the support plate 3, the support plate 3 squeezes the inclined section on the clamping groove 53 on the fixed pressure block 52 to force the inner push section 521 to move, so that the inner push spring 524 connecting the fixed pressure block 52 contracts and accumulates elastic potential energy. When the connecting parts 32 on both sides of the support plate 3 are pressed by the corresponding fixed pressure blocks 52, the elastic potential energy accumulated by the inner push spring 524 tends to be released when the fixed pressure block 52 presses the plate support plate 3, and the inner push spring 524 drives the corresponding fixed pressure blocks 52 to squeeze the support plate 3 inwardly along the width direction. Even if the support plate 3 is disconnected from the middle, or even if a section of the plate in the middle of the support plate 3 needs to be separated from the main body of the support plate 3, the extrusion force applied inwardly by the two fixed pressure blocks 52 along the width direction can maintain the integrity of the support plate 3, thereby reducing the probability of the cut support plate 3 being disconnected from the middle.

[0054] When the support plate 3 needs to be replaced, the driving mechanism 4 begins to extend, and the driving mechanism 4 drives the support frame 1 to move upward in the vertical direction, and the support frame 1 moves synchronously with the support plate 3. As the support frame 1 moves upward, the support frame 1 gradually moves relative to the adjustment rack 55, and the adjustment gear 54 in the support frame 1 meshes with the adjustment rack 55. The adjustment gear 54 drives the transmission rod 51 to rotate. When the transmission rod 51 rotates, it rotates synchronously with the fixed pressure block 52, so that the fixed pressure block 52 gradually moves away from the connecting portion 32 of the support plate 3, and the support plate 3 is rotated. 3 loses the restriction of the fixed pressing block 52, and the support plate 3 is unlocked. However, with the rotation of the transmission rod 51, the maintaining block 56 on the transmission rod 51 abuts against the side wall of the support plate 3. At this time, the maintaining spring 57 releases the accumulated elastic potential energy. Even if the support plate 3 loses the restriction of the fixed pressing block 52, the maintaining blocks 56 located at both ends of the support plate 3 still press the support plate 3 inward along the width direction to maintain the integrity of the support plate 3, thereby avoiding the situation that the cut support plate 3 is disconnected from the middle, causing the damaged plate parts processed on the support plate 3 to fall together.

[0055] The above description is only by way of illustration of certain exemplary embodiments of the present invention. It is undoubted that those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
