The push-pull operation door can facilitate the operator to adjust the sheet 32 on the workbench, etc. Closing the door stop protection 7 during the cutting of the sheet 32 can also ensure the safety of the operator.

[0036] Further, as Figure 2As shown in the figure, there are multiple lower slot plates 9 and multiple upper slot plates 10 arranged on the workbench. Each lower slot plate 9 is provided with a T-shaped slot along the axial direction, and each upper slot plate 10 is also provided with a T-shaped slot along the axial direction. The upper slot plate 10 is located above the lower slot plate 9. Both the lower slot plate 9 and the upper slot plate 10 are made of aluminum alloy. The axis of the lower slot plate 9 is parallel to the axis in the width direction of the workbench, and multiple lower slot plates 9 are evenly arranged along the length direction of the workbench. The axis of the upper slot plate 10 is parallel to the axis in the length direction of the workbench, and the upper slot plate 10 can adjust its position on the workbench according to the size of the plate 32. The T-shaped slot on the upper slot plate 10 serves as the cutting slot in the length direction of the plate 32, and the T-shaped slot on the lower slot plate 9 serves as the cutting slot in the width direction of the plate 32. The cutting mechanism 5 is used to cut the length direction of the plate 32 and slice the width direction of the plate 32. The lifting mechanism 4 is used to control the cutting depth of the cutting mechanism 5. A clamping mechanism 31 is arranged on the workbench. The clamping mechanism 31 has a pressing plate, and the clamping mechanism 31 can fix the plate 32 on the workbench through the pressing plate. A plastic plate is arranged between the pressing plate and the plate 32. Preferably, there are 11 lower slot plates 9.

[0037] In an embodiment of the present invention, the upper slot plates 10 are arranged on the lower slot plates 9 in a matrix form. Multiple upper slot plates 10 form a column of upper slot plates 10 along the width direction of the plate 32, and multiple columns of upper slot plates 10 are arranged in sequence along the length direction of the plate 32. The gap between two adjacent columns of upper slot plates 10 is aligned with the T-shaped slot on the lower slot plate 9.

[0038] Furthermore, it further includes a PLC controller 11. The cross beam 2, the moving frame 3, the lifting mechanism 4, and the cutting mechanism 5 are all driven by motors. The PLC controller 11 can control the cross beam 2, the moving frame 3, the lifting mechanism 4, and the cutting mechanism 5 respectively through the motors.

[0039] Furthermore, as Figure 3 shown, it further includes a water tank 12 and a water inlet pipe 13. The water tank 12 is arranged below the workbench. The water tank 12 is provided with a water pump 14. One end of the water inlet pipe 13 is connected to the water pump 14, and the other end of the water inlet pipe 13 is installed at the position of the cutting mechanism 5. A drain port is arranged on the workbench. The drain port is located above one end of the water tank 12. The water tank 12 is a stepped sewage recovery water tank, as Figure 5As shown in the figure, there are three vertical partitions in the water tank 12. From one end to the other end of the water tank 12, the three partitions are the first partition 15, the second partition 16, and the third partition 17 in sequence. The three partitions divide the water tank 12 into the first water tank 18, the second water tank 19, the third water tank 20, and the fourth water tank 21 in sequence. The water pump 14 is arranged in the fourth water tank 21. The height of the first partition 15 is the same as that of the second partition 16, and the height of the third partition 17 is higher than that of the second partition 16. When the cutting mechanism 5 cuts the sheet 32, the water inlet pipe 13 pumps the water in the fourth water tank 21 to the position of the main shaft 23 under the action of the water pump 14, and cools the cutting blade 24 of the cutting mechanism 5. The water falling on the workbench flows into the first water tank 18 of the water tank 12 through the drain port, and then the water flows over the first partition 15, the second partition 16, and the third partition 17 in sequence and then flows into the fourth water tank 21, realizing the circulating diversion of the cooling water. The sewage generated by cutting the sheet 32 is filtered by the first water tank 18, the second water tank 19, and the third water tank 20 and then recycled.

[0040] Further, as Figure 4 shown, the cutting mechanism 5 includes a main shaft box 22, a main shaft 23, and a cutting blade 24. One end of the main shaft 23 is installed in the main shaft box 22 through a bearing gland 25 and a bearing 26, and the cutting blade 24 is installed at the other end of the main shaft 23 through a cutting blade gland 27 and a left-handed nut 28; the bearing 26 is a 6207 bearing 26, and the outer diameter of the main shaft box 22 is 84 mm.

[0041] Further, it further includes a rotating mechanism, and the rotating mechanism can drive the cutting mechanism 5 to rotate, so that the cutting mechanism 5 can cut the sheet 32 along the length direction and the width direction of the sheet 32 respectively.

[0042] Further, the cutting blade 24 is an ultra-thin resin diamond cutting grinding wheel. The diameter of the cutting blade 24 is 158 mm, the inner hole diameter is 32 mm, and the thickness is 1 mm. When the thickness of the cutting blade 24 exceeds 1 mm, the cutting force is relatively large, which will cause chipping and corner breakage of the sheet 32 made of tungsten molybdenum material, and cause relatively large waste of the material. The cutting blade 24 adopts the ultra-thin resin diamond cutting grinding wheel with the above parameters, which not only reduces material waste, but also reduces cutting resistance, and effectively reduces the phenomenon of material chipping.

[0043] The present invention also discloses a processing method for the sheet 32, which is implemented by using the above-mentioned automatic cutting equipment for the sheet 32, and includes the following steps:

[0044] Step 1, the workbench presses and holds the sheet 32, places the upper trough plate 10 at a suitable position on the workbench, and presses and holds the sheet 32 to be processed on the workbench by using the clamping mechanism 31.

[0045] Draw the actual finished product size lines on the selected sheet 32 according to the drawing and confirm the surface condition of the sheet 32. After the sheet 32 is pressed on the workbench, use infrared to align the actual finished product size lines on the sheet 32 and level the large surface; the thickness of the sheet 32 is T, 1mm ≤ T ≤ 8mm (such as 1mm, 2mm, 3mm, 4mm, 5mm, 6mm, 7mm, 8mm), the length of the sheet 32 is L, 300mm ≤ L ≤ 1500mm (such as: 300mm, 400mm, 500mm, 600mm, 700mm, 800mm, 900mm, 1000mm, 1100mm, 1200mm, 1300mm, 1400mm, 1500mm), the width of the sheet 32 is W, 300mm ≤ W ≤ 1500mm (such as: 300mm, 500mm, 700mm, 900mm, 1100mm, 1300mm, 1500mm), and the material of the sheet 32 is tungsten, molybdenum or tungsten alloy. Place a plastic sheet between the pressing plate and the sheet 32.

[0046] Step 2, install the cutting disc 24. Install the cutting disc 24 on the main shaft 23 and use the left-handed nut 28 and the cutting disc gland 27 to tightly press the cutting disc 24.

[0047] Step 3, set the cutting parameters. Preset the cutting width, total cutting length, cutting speed, cutting direction, cutting times and other cutting parameters in the PLC controller 11. The cutting parameters are adjustable during the cutting process.

[0048] Step 4, cut the sheet 32. Under the control of the PLC controller 11, use the cutting mechanism 5 to cut the length direction of the sheet 32 and slice the width direction, and the lifting mechanism 4 controls the cutting depth.

[0049] When the cutting mechanism 5 cuts the sheet 32, the rotation speed of the cutting disc 24 is 2700 revolutions per minute - 2900 revolutions per minute (such as: 2700 revolutions per minute, 2750 revolutions per minute, 2800 revolutions per minute, 2850 revolutions per minute, 2900 revolutions per minute). If the rotation speed of the cutting disc 24 is too high, the cutting disc 24 will be severely worn. If the rotation speed is too low, the cutting force will be insufficient and the cutting disc will break or chip. The cutting speed of the cutting mechanism 5 is 0.8mm / s - 1.5mm / s. For sheets 32 with different materials and thicknesses, use the corresponding cutting speed processing parameters. The cutting speed processing parameters are shown in Table 1.

[0050] Table 1 Cutting speed processing parameters

[0051]

[0052] A method for high-speed continuous cutting of tungsten, molybdenum, and tungsten alloy materials with a thickness of less than 8 mm using the sheet material 32 automatic cutting equipment. The cutting mechanism 5 is controlled by a PLC controller 11 to move along the x / y / z axes (the x-axis is the length direction of the sheet material 32, the y-axis is the width direction of the sheet material 32, and the z-axis is the depth direction). By combining parameters such as the rotation of the cutting blade 24 driven by a belt and the cutting feed, high-efficiency processing is achieved. At the same time, by adjusting the processing parameters, the optimal processing state is determined for different materials. Using this processing method, the cutting feed for tungsten sheet materials with a thickness of 1 - 3 mm can reach 60 mm / min, for molybdenum sheet materials it can reach 90 mm / min, and for tungsten alloy sheet materials it can reach 90 mm / min. For tungsten sheet materials with a thickness of 3 - 8 mm, the cutting feed can reach 48 mm / min, for molybdenum sheet materials it can reach 60 mm / min, and for tungsten alloy sheet materials it can reach 60 mm / min. There is no obvious broken edge for tungsten and molybdenum materials. The cutting speed for the same specification and the same material is more than 7 times better than that of the fast wire cutting machine, and the segmentation accuracy is within 0.2 mm. Compared with a sawing machine, the waste material generated is reduced by more than 2 times.

[0053] In an embodiment of the present invention, 1108 products are processed using this cutting equipment. The rough cutting size is 20(+3.5 / +3.8)*671.7(+3.5 / +3.8). The average cutting time for each piece is 10 minutes, and the processing time for 1108 pieces is 184 hours. The efficiency is increased by 7 times. Without considering the wear of the cutting blade 24, the efficiency can be up to more than 18 times faster than that of the fast wire cutting machine. Without considering deformation, the accuracy of the cut finished sheet material 32 with a length within 300 mm can be controlled within 0.2 mm. Compared with a sawing machine, the waste material generated is reduced by more than 2 times.

[0054] From the above description, it can be seen that the above embodiments of the present invention achieve the following technical effects:

[0055] An automatic sheet cutting equipment and processing method, which uses this cutting equipment to cut and segment tungsten, molybdenum, or tungsten alloy sheet materials 32, reduces material waste, effectively reduces the phenomenon of material edge collapse, improves the cutting efficiency, and reduces the cost.
