Embodiment Construction
[0007] The present invention is further illustrated below by specific examples.
[0008] Such as figure 1 As shown, the method for cutting the metal explosion-proof belt of the silent and dust-free display of the present invention adopts a pneumatic compression CRT device, a hydraulically driven custom-made cutting tool cuts off the metal explosion-proof of the CRT and includes the following steps:
[0009] Step 1: The CRT to be cut is manually placed between the platforms; the automatic clamping device positions it to ensure cutting stability.
[0010] Open the pneumatic compression driving device 5, the air source: 0.8MPa. Make the CRT be compressed and fixed and close to the hydraulically driven cutter;
[0011] Step 2: The hydraulically driven cutting device starts to move towards the metal explosion-proof belt of the CRT under the control of the set program;
[0012] Step 3: The positioning insert 3 is first inserted between the metal explosion-proof belt and the CRT ...

In the process of disassembling, processing and utilizing waste televisions, screen and cone separation and fluorescent powder removing must be carried out on a cathode-ray tube, and leaded cone glass and screen glass are separated to be utilized respectively. When the cathode-ray tube is manufactured, in terms of safety, explosion-proof reinforcing is carried out on the screen glass through a metal belt. At present, a handheld grinding machine is used for carrying out cutting at home and abroad, and consequently, noise is big, and safety is poor. According to a method, a special hydraulic cutting device is utilized for cutting the explosion-proof belt, and the problem that the noise pollution and the potential safety hazard exist in the industry for a long term is solved. The method is applied to a metal packaging belt to be cut.
Description
Technical field [0001] The present invention involves a metal cutting method tightly on an object, especially the cutting method of cathode radio -anti -explosion band during the disassembly of waste TV. Background technique [0002] During the recycling, disassembly, and utilization of electronic waste, the number of disassembly of waste televisions is the largest, and about 90%of the recycling volume of TVs, refrigerators, air conditioners, computers, and washing machines in Chinese TVs.Therefore, technical equipment for disassembly and utilization of abandoned TVs has been developed at home and abroad.During the disassembly of the waste TV, in order to prevent environmental pollution, the cathode ray tube in the TV must first cut off the explosion -proof band on the CRT CRT.Due to the special position of the special structure and explosion -proof band on the cathode tube CRT, the cathode tube CRT CRT currently uses a handheld sand -holding wheel to cut the explosion -proof zon...
