Technical Field
[0001] This utility model relates to the field of sheet metal processing technology, specifically to a sheet metal processing and cutting device for subway electromagnetic shielding doors. Background Technology
[0002] With the rapid development of urban rail transit, subways have become an important mode of transportation for people's daily travel. Subway electromagnetic shielding doors play a crucial role in ensuring passenger safety, improving subway operating efficiency, and reducing energy consumption. Electromagnetic shielding doors effectively prevent people and objects from accidentally falling into the track area, while reducing air convection between the platform and the tracks, lowering the energy consumption of the air conditioning system, and reducing the impact of noise and dust on the platform environment. Electromagnetic shielding doors are typically made of sheet metal, and sheet metal processing is a key step in their manufacturing process. The cutting process is an important step in cutting the raw metal sheet into specific shapes and sizes according to design requirements.
[0003] Existing sheet metal processing and cutting equipment for subway electromagnetic shielding doors has some shortcomings. On the one hand, traditional equipment may simply place the material on the cutting table without effective fixing measures, making it prone to displacement during the cutting process. While some equipment has fixing mechanisms to secure the sheet metal parts, they lack the ability to correct the parts, resulting in inaccurate placement and potentially preventing precise cutting to the required shape. On the other hand, traditional cutting equipment may have poor dust extraction, causing harmful gases and dust generated during cutting to permeate the working environment. Additionally, replacing filter components may be inconvenient. Utility Model Content

For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances.
[0026] Example 1:
[0027] Please see Figure 1-3 This utility model provides a technical solution: a sheet metal processing and cutting device for subway electromagnetic shielding doors, including a cutting table 1, a support frame 2 on the top of the cutting table 1, a laser cutting group 3 extending from the bottom inside the support frame 2, a fixing and correction mechanism 4 inside the cutting table 1, and a dust suction and filtering mechanism 5 on the top of the support frame 2.
[0028] The fixed correction mechanism 4 includes a fixing component 41 and a correction component 42. The fixing component 41 is disposed inside the cutting table 1, and the correction component 42 is disposed on the top of the cutting table 1.
[0029] Furthermore, the fixing component 41 includes a fixing motor 411, which is disposed on the inner wall of the bottom of the cutting table 1. A rotating rod 412 is fixedly connected to the output end of the fixing motor 411. A connecting rod 413 is rotatably connected to the top of the rotating rod 412. A fixing frame 414 is rotatably connected to the end of the connecting rod 413 away from the rotating rod 412. When the fixing motor 411 is started, the rotating rod 412 can be rotated, which in turn drives the connecting rod 413 and the fixing frame 414 to move back and forth.
[0030] Furthermore, there are two connecting rods 413 and fixed frames 414, which are symmetrically distributed on the left and right sides with the fixed motor 411 as the center line. The fixed frames 414 are provided with sliding grooves at the corresponding positions of the cutting table 1, and the fixed frames 414 are slidably connected inside the sliding grooves. The two fixed frames 414 will move back and forth synchronously, so that the material to be cut is always in the middle of the cutting table 1.
[0031] Furthermore, the straightening assembly 42 includes an adjusting lever 421, which is rotatably connected to the back of the fixed frame 414. A first bevel gear 422 is fixedly connected to one end of the adjusting lever 421. A bidirectional spiral rod is rotatably connected between the left and right inner walls of the fixed frame 414. A second bevel gear 424 is fixedly connected to the surface of the bidirectional spiral rod. A straightening frame 425 is threadedly connected to the surface of the bidirectional spiral rod. A right-angle straightener 426 is rotatably connected to the bottom of the straightening frame 425. The rotatable right-angle straightener 426 can straighten the material to be cut that it comes into contact with.
[0032] Furthermore, the first bevel gear 422 and the second bevel gear 424 mesh with each other. There are two straightening frames 425 and right-angle straighteners 426, which are symmetrically distributed on the surface of the bidirectional threaded rod 423 with the adjusting lever 421 as the center. Rotating the adjusting lever 421 can drive the first bevel gear 422 to rotate, thereby driving the second bevel gear 424 and the bidirectional threaded rod 423 to rotate. The bidirectional threaded rod 423 can make the two straighteners move synchronously inward or outward when the bidirectional threaded rod 423 rotates.
[0033] Example 2:
[0034] Please see Figure 4-6 In conjunction with Embodiment 1, the dust collection and filtration mechanism 5 includes a dust collection motor 51, which is located at the bottom of the support frame 2. A sludge collection tank 52 is fixedly connected to the outside of the dust collection motor 51. A dust collection pipe 53 is fixedly connected to the right side of the sludge collection tank 52. A dust collection head 54 is fixedly connected to the end of the dust collection pipe 53 away from the sludge collection tank 52. A filter plate 55 is slidably connected inside the sludge collection tank 52. A fixing rod 56 is fixedly connected inside the filter plate 55. A threaded knob 57 is threadedly connected to the surface of the fixing rod 56. A pressing rod 58 is slidably connected inside the fixing rod 56. A first spring 59 is fixedly connected between the top of the pressing rod 58 and the inner wall of the fixing rod 56. A fixing plate 510 is rotatably connected to the end of the pressing rod 58 near the first spring 59. A second spring 511 is fixedly connected to the inner side of the fixing plate 510 and the surface of the pressing plate. The dust collection head 54 can draw the harmful gases generated by the laser cutting group 3 into the sludge collection tank 52, while the filter plate 55 can filter the harmful substances, which can effectively reduce air pollution.
[0035] Furthermore, a groove is provided at the corresponding position of the fixing plate 510 and the fixing rod 56, and the fixing plate 510 is slidably connected inside the groove. There are four fixing plates 510 and four second springs 511, which are distributed in a circle on the top of the pressing rod 58. Pressing the pressing rod 58 can retract the fixing plate 510, at which time the filter plate 55 can be pulled out, and the threaded knob 57 can fix the filter plate 55.
[0036] In actual operation, when this device is used, the material to be cut is placed on the cutting table 1, the fixed motor 411 is started, and the fixed frame 414 can fix the material left and right. The right angle correctors 426 set on both sides of the fixed frame 414 can straighten the material when in contact with it. When it is necessary to cut materials of different widths, the distance adjustment lever 421 can be rotated to adjust the distance between the right angle correctors 426. After adjusting to the required distance, materials of different widths can be straightened and cut. When the material is straightened and ready to be cut, the laser is started. Cutting assembly 3 cuts the material, then starts the vacuum motor 51. The vacuum motor 51 sucks the harmful gases generated during cutting from the vacuum head 54 to the sludge collection tank 52, and discharges them after being filtered by the filter plate 55. When the filter plate 55 needs to be replaced, simply loosen the threaded knob 57 and press the pressing rod 58. At this time, the fixing plate 510 retracts, and the filter plate 55 can be pulled out. After cleaning the filter plate 55, simply press the pressing rod 58 again to put the filter plate 55 back in place, and then tighten the threaded knob 57 to fix the filter plate 55.
