DETAILED DESCRIPTION

[0020] The present invention is further described in detail below in conjunction with the accompanying drawings and embodiments, wherein the same components are represented by the same reference numerals.

[0021] like Figure 1-4 As shown, an 80kw laser cutting machine tool includes a frame 1, on which an installation space 2 is formed. The frame 1 is formed by connecting the ends of multiple beams and columns to form a rectangular installation space 2.

[0022] Preferably, a support unit 3 is further included, and the support unit 3 is installed in the installation space 2. The support unit 3 includes a plurality of installation plates 4 arranged in sequence, and the installation plates 4 are provided with a plurality of installation positions 5 along the length direction, and the installation plates 4 are provided with installation cavities 6 corresponding to the installation positions 5.

[0023] Preferably, a support sheet 7 is also included, the upper end of the support sheet 7 is used to support the workpiece, the lower end of the support sheet 7 forms a connecting end 8 which is plugged into the mounting cavity 6, a connecting unit 9 is provided in the mounting cavity 6, the connecting unit 9 is respectively connected to the mounting cavity 6 and the connecting end 8, and the connecting unit 9 is used to drive the support sheet 7 to move toward the mounting sheet 4 after being heated, so as to form a processing gap 10 between the upper end of the support sheet 7 and the workpiece.

[0024] When in use, multiple support sheets 7 are sequentially plugged into the installation cavity 6, and at the same time, the connecting unit 9 is respectively connected to the installation cavity 6 and the connecting end 8, and the workpiece is further moved to the installation space 2, and the support is completed by the upper end of the support sheet 7. During the processing, the laser directly irradiates the surface of the workpiece, causing the surface temperature of the workpiece to rise sharply, thereby quickly transferring the temperature along the support sheet 7 to the connecting unit 9. After being heated, the connecting unit 9 drives the support sheet 7 to move, thereby forming a processing gap 10 to avoid welding between the support sheet 7 and the workpiece at the processing position.

[0025] At the same time, since the workpiece transfers heat to the connecting unit 9 through the supporting sheet 7, the heat can be greatly reduced, thereby avoiding movement failure caused by overheating of the connecting unit 9.

[0026] Preferably, the connecting unit 9 includes a first magnetic member 11, a second magnetic member 12 and a spring 13, the connecting end 8 is provided with a limit plate 14, the mounting cavity 6 is provided with a limit surface 15 corresponding to the limit plate 14, the limit surface 15 is used to contact the limit plate 14 to limit the connecting end 8 to move only within the mounting cavity 6, the two ends of the spring 13 are respectively connected to the limit plate 14 and the mounting cavity 6 and are used to drive the limit plate 14 to move toward the bottom of the mounting cavity 6, the first magnetic member 11 and the second magnetic member 12 are respectively provided corresponding to the limit surface 15 and the limit plate 14, the first magnetic member 11 is used to magnetically connect the second magnetic member 12, so that the limit plate 14 contacts the limit surface 15, and the spring 13 is pulled to obtain elastic force.

[0027] In the initial state, the first magnetic member 11 and the second magnetic member 12 are magnetically connected to each other. At this time, the spring 13 is pulled to obtain elastic force. When the laser processes the workpiece, due to the contact between the limit plate 14 and the limit surface 15, the temperature of both will rise rapidly, so that the magnetic force of the first magnetic member 11 and the second magnetic member 12 is greatly reduced, so that the second magnetic member 12 and the first magnetic member 11 are separated from each other under the drive of the spring 13, that is, the support plate 7 is driven to move to complete the retraction of the support plate 7. At the same time, after the limit plate 14 and the limit surface 15 are cooled, the magnetic force of the first magnetic member 11 and the second magnetic member 12 is restored, so that the magnetic force of the two is used to complete the retraction, thereby realizing the reset of the support plate 7.

[0028] At the same time, the magnetic force and the spring 13 can be used to drive the limit plate 14 to move quickly, so that the position of the limit plate 14 is more fixed, thereby avoiding the diagonal support of multiple support sheets 7 in sequence, thereby improving the support stability.

[0029] At the same time, by setting the first magnetic member and the second magnetic member 12 , the position of the limiting plate 14 and the position of the limiting plate 14 can be positioned by adsorption of the two, thereby improving the accuracy of the position of the supporting plate 7 after movement.

[0030] Preferably, a fan unit is also included. The fan unit is a prior art and will not be described in detail here. A connecting passage 16 is provided in the mounting plate 4. The mounting cavity 6 and the connecting passage 16 are arranged up and down. The connecting passage 16 is used to connect multiple mounting cavities 6 in sequence. The fan unit is connected to the connecting passage 16 through a pipeline and is used to supply air to the connecting passage 16. An air outlet 17 is provided on the side of the mounting plate 4 corresponding to the mounting cavity 6.

[0031] The fan unit cooperates with the connecting passage 16 to achieve simultaneous cooling of the plurality of mounting cavities 6 , thereby accelerating the return speed of the support sheet 7 .

[0032] Preferably, a cooling cavity 18 is formed in the support plate 7, and the cooling cavity 18 includes limiting edges 19 vertically arranged on both sides. A cooling member 20 that matches the shape of the cooling cavity 18 is provided in the installation cavity 6, and the two sides of the cooling member 20 are respectively slidably limited by the two limiting edges 19. When the first magnetic member 11 and the second magnetic member 12 are separated from each other, the spring 13 drives the support plate 7 to move so that the cooling member 20 and the cooling cavity 18 fit each other.

[0033] When the spring 13 drives the support plate 7 to move toward the mounting plate 4 , the cooling member 20 can fit into the cooling cavity 18 , so that the support plate 7 can be quickly cooled by the cooling member 20 , thereby increasing the return speed of the support plate 7 .

[0034] At the same time, the setting of the limiting edge 19 can cooperate with the spring 13 to limit the movement of the support piece 7, thereby improving the stability of the movement of the support piece 7.

[0035] Preferably, the cooling member 20 includes two symmetrically arranged plates 21 , a cooling zone 22 is formed between the two plates 21 , and the mounting cavity 6 is provided with a connecting hole 23 corresponding to the cooling zone 22 and is connected with the connecting passage 16 through the connecting hole 23 .

[0036] Specifically, the sheet body 21 is made of ceramic material.

[0037] The setting of the cooling zone 22 can cooperate with the sheet body 21 to improve the cooling and heat dissipation effect of the support sheet 7. At the same time, the support sheet 7 and the sheet body 21 can be cooled simultaneously through the airflow, and the contact range of the airflow can be maximized to improve the cooling effect.

[0038] Preferably, a receiving cavity 24 is provided at the bottom of the installation cavity 6 corresponding to the spring 13, the spring 13 is located in the receiving cavity 24, an annular cooling surface 25 is formed at the upper end of the receiving cavity 24, and a heat conducting surface 26 connected to the connecting passage 16 is provided at the bottom of the installation plate 4, and the spring 13 is used to drive the limit plate 14 to resist the cooling.

[0039] The provision of the cooling surface 25 can cool the second magnetic member 12 after the support sheet 7 moves, so as to accelerate the magnetic recovery of the second magnetic member 12 . At the same time, the cooling effect of the cooling surface 25 is achieved by the heat conducting surface 26 and the connecting passage 16 .

[0040] Preferably, the mounting piece 4 is provided with a contact plate 27 corresponding to the mounting position 5 , the limiting surface 15 is a side surface of the contact plate 27 , both ends of the contact plate 27 are connected to the mounting piece 4 by bolts, and the contact plate 27 is provided with a through hole corresponding to the support piece 7 .
