The bottom of the first connecting plate contacts the plate. During the extrusion process, the pulley will encounter plates of various thicknesses. The first spring can automatically adjust the spacing of the elastic blocks to ensure that the pulley always maintains appropriate contact and extrusion force, thereby improving the extrusion effect and reducing the impact of some water arrows on the plate and the water jet equipment caused by the water arrow passing through the gap between the first connecting plate and the plate.

DETAILED DESCRIPTION

[0023] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the present invention is further described below in conjunction with specific implementation methods.

[0024] like Figures 1 to 3 As shown, a plate cutting device described in an embodiment of the utility model comprises a workbench 1; a water jet device 11 is slidably connected above the workbench 1; the water jet device 11 is moved laterally by a screw nut pair; a first connecting plate 12 is sleeved on the middle of the water jet device 11; the water jet device 11 and the first connecting plate 12 are connected by multiple groups of thin rods; the first connecting plate 12 is arc-shaped; the lower interior of the first connecting plate 12 is hollow; multiple groups of first springs 13 are fixedly connected inside the first connecting plate 12; an elastic block 14 is fixedly connected to the end of the first spring 13; a pulley 15 is rotatably connected to the inner side wall of the elastic block 14; a short rod is rotatably connected between the pulley 15 and the elastic block 14; when working, the plate to be cut is placed on the workbench 1, and the water jet device 11 is turned on to control the movement direction of the water jet device 11 through the screw nut pair and the sliding on the workbench 1, so that the water jet device 11 can cut the plate in all directions. When the water jet device 11 contacts the plate, the water arrows it ejects have extremely strong kinetic energy and impact force, and still have strong impact force after cutting the plate. When the water arrow contacts the first connecting plate 12, due to the arc setting of the first connecting plate 12, the splash distance of the water arrow is reduced, so that the water arrow slides on the inner side wall of the first connecting plate 12, reducing the impact of the water arrow flying out from the top of the first connecting plate 12 on the plate and the workbench 1. The bottom of the first connecting plate 12 contacts the plate. During the extrusion process, the pulley 15 will encounter plates of various thicknesses. The first spring 13 can automatically adjust the spacing of the elastic block 14 to ensure that the pulley 15 always maintains appropriate contact and extrusion force, thereby improving the extrusion effect and reducing the impact of some water arrows on the plate and the water jet device 11 caused by the water arrow passing through the gap between the first connecting plate 12 and the plate. When the water jet device 11 finishes working on the plate, the cutting of the plate to become the outer contour of the charging door is completed.

[0025] like Figure 2As shown, a first fixed net 2 is fixedly connected to the middle of the inner wall of the first connecting plate 12; a plurality of first connecting rods 21 are fixedly connected to the inner wall of the first connecting plate 12; an annular tube 22 is fixedly connected to the end of the first connecting rod 21; adjacent annular tubes 22 are connected by a plurality of pipes; a plurality of slots 23 are provided at the bottom of the annular tube 22; the middle of the annular tube 22 close to the water jet device 11 is connected to a water pump through a conduit; water flows out continuously from the slots 23 in the annular tube 22 by connecting the water pump. When the water jet device 11 is in operation, the ejected water arrows contain corundum. When the water arrows slide down the inner wall of the first connecting plate 12, the corundum contained in the water arrows will adhere to the first fixed net 2, thereby realizing the recycling of resources and reducing the use cost. At the same time, when the ejected water arrows pass through the upper water flow, the water flow will cause a certain resistance to the water arrows, thereby reducing the speed and impact force of the water arrows, reducing the cutting error and workpiece surface damage caused by excessive impact force, and improving the cutting quality and precision.

[0026] like Figure 1 to Figure 2 As shown, the outer wall of the first connecting plate 12 is fixedly connected with multiple groups of articulated frames 3; the middle part of the articulated frame 3 is rotatably connected with a second connecting rod 31; the middle part of the second connecting rod 31 is fixedly connected with a second spring 32; the end of the second spring 32 is fixedly connected to the outer wall of the first connecting plate 12; the end of the second connecting rod 31 is rotatably connected to a universal ball 33; when the water jet equipment 11 is running, the second connecting rod 31 will be connected to the first connecting plate 12 through the second spring 32 to adjust the position of the universal ball 33, and the plate is squeezed through the universal ball 33, thereby reducing the shaking of the plate during cutting and ensuring the integrity and quality of the plate.

[0027] like Figures 1 to 5 As shown, a second fixed net 4 is fixedly connected under the workbench 1; the second fixed net 4 is set in an inclined W shape; when the water jet device 11 completes its work, the water arrows will enter under the workbench 1 by splashing, and the water under the workbench 1 will immerse the second fixed net 4. When the water arrows enter under the workbench 1, they are buffered by water, and the corundum they carry adheres to the second fixed net 4. Moreover, through the W-shaped setting of the second fixed net 4, more corundum will move to the bottom and gather, making collection more convenient.

[0028] like Figure 4 As shown, a third connecting rod 5 is fixedly connected to the outermost iron sheet on the workbench 1; a third spring 51 is sleeved on the middle part of the third connecting rod 5; the end of the third spring 51 is fixedly connected to the first magnet 52; when the plate is placed on the outermost side of the workbench 1 and directly above the third connecting rod 5, the first magnet 52 on the third connecting rod 5 will be attracted to the plate through the third spring 51, and the contact between the third spring 51 and the plate reduces the movement or vibration caused by the impact of the water arrow when the water jet device 11 is running, thereby increasing the stability and accuracy of cutting.

[0029] like Figure 1 and Figure 5 As shown, a plurality of groups of second magnets 6 are fixedly connected to the middle of the second fixed net 4; when the water arrow enters under the workbench 1, the metal chips carried therein are attracted by the second magnet 6 fixed to the middle of the second fixed net 4. By providing the second magnet 6, the mixing of metal chips and corundum is reduced, thereby reducing the difficulty of corundum recovery and processing.

[0030] like Figure 4 As shown, a waterproof cloth 7 is provided in the middle of the third spring 51; when the plate is placed on the workbench 1, the third spring 51 is easy to react with air and water to generate rust, resulting in breakage, thereby causing the first magnet 52 to separate from the third spring 51. By providing the waterproof cloth 7, the breakage of the third spring 51 caused by rust is reduced, resulting in the problem that the plate cannot be fixed any further.

[0031] Working principle: Place the plate to be cut on the workbench 1, turn on the water jet device 11, and control the movement direction of the water jet device 11 through the screw nut pair and the sliding on the workbench 1, so that the water jet device 11 can cut the plate in all directions. When the water jet device 11 contacts the plate, the water arrow sprayed by it has extremely strong kinetic energy and impact force, and still has a strong impact force after cutting the plate. When the water arrow contacts the first connecting plate 12, due to the arc setting of the first connecting plate 12, the splash distance of the water arrow is reduced, so that the water arrow slides on the inner side wall of the first connecting plate 12, reducing the impact on the plate and the workbench 1 caused by the water arrow flying out from the top of the first connecting plate 12. The bottom of the first connecting plate 12 contacts the plate, and the water arrow is squeezed. During the process, the pulley 15 will encounter plates of various thicknesses. The first spring 13 can automatically adjust the spacing of the elastic block 14 to ensure that the pulley 15 always maintains appropriate contact and extrusion force, thereby improving the extrusion effect and reducing the impact of the water arrow on the plate and the water jet device 11 caused by the water arrow passing through the gap between the first connecting plate 12 and the plate. By connecting the water pump, water flows continuously out of the slot 23 in the annular tube 22. When the water jet device 11 is in operation, the ejected water arrow contains corundum. When the water arrow slides down the inner wall of the first connecting plate 12, the corundum contained in the water arrow will adhere to the first fixed net 2, realizing the recycling of resources and reducing the cost of use. At the same time, when the ejected water arrow passes through the upper water flow, the water flow will cause damage to the water arrow. A certain resistance is formed, thereby reducing the speed and impact force of the water arrow, reducing the cutting error and workpiece surface damage caused by excessive impact force, and improving the cutting quality and accuracy. The second connecting rod 31 will be connected to the first connecting plate 12 through the second spring 32 to adjust the position of the universal ball 33, and the plate is squeezed by the universal ball 33, which reduces the shaking of the plate during cutting and ensures the integrity and quality of the plate. When the water jet device 11 completes the work, the water arrow will splash into the bottom of the workbench 1, and the water under the workbench 1 will submerge the second fixed net 4. When the water arrow enters the bottom of the workbench 1, it will be buffered by the water, and the diamond sand it carries will adhere to the second fixed net 4, placing the plate on the outermost side of the workbench 1, and when it is directly above the third connecting rod 5 The first magnet 52 on the third connecting rod 5 will be attracted to the plate through the third spring 51. The contact between the third spring 51 and the plate reduces the movement or vibration caused by the impact of the water arrow when the water jet device 11 is running, thereby increasing the stability and accuracy of cutting. When the water arrow enters under the workbench 1, the metal chips carried therein are attracted by the second magnet 6 fixed to the middle of the second fixed net 4. By setting the second magnet 6, the mixing of metal chips and corundum is reduced, and the difficulty of corundum recovery is reduced. When the plate is placed on the workbench 1, the third spring 51 is easy to react with air and water to generate rust and cause breakage, thereby causing the first magnet 52 to separate from the third spring 51. By setting the waterproof cloth 7, the breakage caused by rust of the third spring 51 is reduced.This causes the panel to be unable to be fixed any further.
