DETAILED DESCRIPTION

[0026] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0027] See also Figure 1-5The utility model provides a technical solution: an anti-splash positioning platform, comprising: two groups of positioning components 3 for crimping and positioning cutting materials, a transmission platform 2 for adjusting the spacing between the two groups of positioning components 3 is provided at the bottom of the positioning component 3, and an adsorption component 1 for preventing metal sparks from splashing is provided at the bottom of the transmission platform 2.

A slot 12 is opened on the top of the adsorption box 13, and the slot wall of the slot 12 is slidably connected to the outside of the filter screen 11.

[0029] Furthermore, during the cutting process, the exhaust fan 14 remains in working condition. Under the action of the exhaust fan 14, a negative pressure is formed in the collection box 15, so that after the metal material is cut through, the generated metal sparks and metal particles will be ejected from the back of the material and passed through the strip through hole 26 and sucked into the collection box 15, thereby avoiding the splashing of metal sparks and making the operation of the staff safer. The metal particles will be filtered by the filter screen 11 and remain in the collection box 15 to avoid being discharged by the exhaust fan 14. At the same time, the filter screen 11 can be pulled out from the slot 12, making it more convenient to clean and replace the filter screen 11.

[0030] The transmission platform 2 includes: a carrier plate 21, the bottom of which is connected to the top of the collection box 15 by screws, and a limiting slide groove 24 is provided in the middle of the top of the carrier plate 21. The groove wall of the limiting slide groove 24 is slidably connected to the sides of the two groups of moving sliders 23, the insides of the two groups of moving sliders 23 are both threadedly connected to the outsides of the left and right screw rods 25, one end of the left and right screw rods 25 is connected to the output shaft of the driving motor 1 22 through a coupling, and the outside of the driving motor 1 22 is fixedly connected to the side of the carrier plate 21. A plurality of groups of strip through holes 26 are evenly provided on the top of the carrier plate 21, and the strip through holes 26 are located on both sides of the limiting slide groove 24.

[0031] Furthermore, the drive motor 22 is started, and the drive motor 22 drives the left and right rotating screws 25 to rotate. The left and right rotating screws 25 drive the two groups of movable sliders 23 to move closer to or away from each other. The two groups of movable sliders 23 in turn drive the two groups of positioning components 3 to move closer to or away from each other, thereby changing the spacing between the two groups of positioning components 3, and adjusting the two groups of positioning components 3 to a suitable spacing according to the size of the metal material.

[0032] The positioning assembly 3 includes: a right-angle support plate 34, the bottom of which is fixedly connected to the top of the moving slider 23, and the center of the top of the right-angle support plate 34 is threadedly connected to the side of the screw rod 31. The bottom end of the screw rod 31 is connected to the output shaft of the second driving motor 35 through a coupling, the outside of the second driving motor 35 is fixedly connected to the top of the lifting plate 37, and the top of the lifting plate 37 is fixedly connected to the bottom of the four groups of guide rods 33. The sides of the four groups of guide rods 33 are slidably inserted into the four corners of the top of the right-angle support plate 34, and the tops of the four groups of guide rods 33 are respectively fixedly connected to the bottom of the limit block 32. The inner sides of the two ends of the lifting plate 37 are slidably sleeved on the sides of the sliding column 38, the top of the sliding column 38 is fixedly connected to the bottom of the limit plate 36, and the bottom of the sliding column 38 is fixedly connected to the top of the crimping plate 310. The side of the sliding column 38 is slidably inserted into the inner circle of the spring 39 , and both ends of the spring 39 are supported between the lifting plate 37 and the crimping plate 310 .

[0033] Furthermore, the metal material to be cut is placed on the loading plate 21 and then the drive motor 2 35 is started. The drive motor 2 35 drives the screw rod 31 to rotate clockwise, so that the screw rod 31 moves downward. The screw rod 31 pushes the drive motor 2 35 downward, and the drive motor 2 35 drives the lifting plate 37 downward. The lifting plate 37 compresses the spring 39. Under the elastic force of the spring 39, the crimping plate 310 is pressed on the metal material to crimp and position the metal material to avoid displacement of the metal material during the cutting process.

[0034] Furthermore, the downward movement of the screw rod 31 is controlled by controlling the number of clockwise rotations of the drive motor 2 35 to drive the screw rod 31, thereby changing the compression amount of the spring 39 by the lifting plate 37. The compression amount of the spring 39 is different, and the pressure of the crimping plate 310 on the metal material is also different. In this way, the pressure of the crimping plate 310 on the metal material can be adjusted according to the metal material of different thickness and material, thereby improving the applicability of the equipment.

[0035] A plasma cutting device includes a spatter-proof positioning platform.

[0036] Working principle: When in use, first adjust the two groups of positioning components 3 to a suitable spacing according to the size of the metal material, start the drive motor 22, the drive motor 22 drives the left and right rotating screws 25 to rotate, the left and right rotating screws 25 drive the two groups of moving sliders 23 to move closer to or away from each other, and the two groups of moving sliders 23 drive the two groups of positioning components 3 to move closer to or away from each other, thereby changing the spacing between the two groups of positioning components 3.

[0037] Then, the metal material to be cut is placed on the loading plate 21 and then the driving motor 2 35 is started. The driving motor 2 35 drives the screw rod 31 to rotate clockwise, so that the screw rod 31 moves downward, and the screw rod 31 pushes the driving motor 2 35 downward. The driving motor 2 35 drives the lifting plate 37 to move downward, and the lifting plate 37 compresses the spring 39. Under the elastic force of the spring 39, the crimping plate 310 is pressed on the metal material to crimp and position the metal material to avoid the metal material from shifting during the cutting process; the downward movement of the screw rod 31 is controlled by controlling the number of clockwise rotations of the screw rod 31 driven by the driving motor 2 35, thereby changing the compression amount of the spring 39 by the lifting plate 37. The compression amount of the spring 39 is different, and the pressure of the crimping plate 310 on the metal material is also different. In this way, the pressure of the crimping plate 310 on the metal material can be adjusted according to the metal materials of different thicknesses and materials, thereby improving the applicability of the equipment.

[0038] During the cutting process, the exhaust fan 14 keeps working. Under the action of the exhaust fan 14, the collection box 15 forms a negative pressure, so that after the metal material is cut through, the generated metal sparks and metal particles will be ejected from the back of the material and passed through the strip through hole 26 and sucked into the collection box 15, avoiding the splashing of metal sparks and making the operation of the staff safer. The metal particles will be filtered by the filter screen 11 and remain in the collection box 15 to avoid being discharged by the exhaust fan 14. At the same time, the filter screen 11 can be pulled out from the slot 12, making it more convenient to clean and replace the filter screen 11.
