DETAILED DESCRIPTION

[0027] Embodiments of the present invention are described in detail below, examples of which are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are intended to be used to explain the present invention, and should not be construed as limiting the present invention.

[0028] First embodiment

[0029] See also Figure 1 and Figure 2 , Figure 1 is a schematic diagram of the overall structure of the first embodiment of the present invention, Figure 2 It is an overall front view of the first embodiment of the present invention.

[0030] The present invention provides a low-ignition-point metal processing center, including a base 1 and a processing host 2, wherein the processing host 2 includes a closed cover 201, a tool magazine 202, a protective plate 204, a brush plate 206, a processing table 203 and a power shaft 205. The above-mentioned solution solves the problem that when the processing material is a flammable material (such as aluminum alloy), a large amount of lightweight and flammable metal debris will be generated due to machine tool processing, and there is a risk of the debris being ignited by the flash combustion phenomenon and causing a fire, which poses a certain safety hazard. It can be understood that when the above-mentioned solution can be used to process metal materials, a small amount of debris will adhere to the tool when processing the material. When the tool is replaced, the debris may be blown away with the tool. When the tool enters the tool magazine 202 for storing the tool, when the amount of debris in the tool magazine 202 increases, the risk of fire will increase. Therefore, the brush plates 206 are respectively provided on the front and rear sides of the opening for the tool to enter and exit the tool magazine 202. When the tool passes through the opening, the brush plate 206 will sweep across the surface of the tool, and can sweep off the trace debris adhering to the surface of the tool to avoid the debris from mixing into the tool magazine 202. This will effectively solve the problem that when the processing material is flammable material (such as aluminum alloy), a large amount of lightweight and flammable metal debris will be generated due to machine tool processing, and there is a risk of the debris being ignited by the flash combustion phenomenon and causing a fire, which poses a certain safety hazard.

[0031] According to this specific embodiment, the closed cover 201 is fixedly connected to the base 1 and is located on the upper outer surface of the base 1. One end of the tool magazine 202 passes through the closed cover 201 and is arranged above the base 1. The other end of the tool magazine 202 is arranged above the closed cover 201. The protective plate 204 is detachably connected to the tool magazine 202 and is located on one side of the tool magazine 202, and the protective plate 204 is arranged below the closed cover 201. The brush plate 206 is fixedly connected to the tool magazine 202 and is located below the tool magazine 202, and the brush plate 206 and the protective plate 204 are arranged vertically. The closed cover 201 is the main functional protective component for protecting the whole, and the tool magazine 202 is a place for storing tools, and the protective plate 204 and the brush plate 206 will be auxiliary components for cleaning metal debris remaining on the tools.

[0032] The processing table 203 is slidably connected to the base 1 and is located above the base 1 . The processing table 203 is disposed inside the closed cover 201 , and is also disposed obliquely below the tool magazine 202 .

[0033] Secondly, one end of the power shaft 205 passes through the closed cover 201 and is arranged above the base 1, and the power shaft 205 is arranged above the processing table 203, and the other end of the power shaft 205 is arranged above the closed cover 201, and the power shaft 205 is arranged on one side of the tool magazine 202.

[0034] When the present invention is used to process metal materials, since the tool will adhere to a trace amount of debris when processing the material, when the tool is replaced, the debris may enter the tool magazine 202 for storing the tool along with the tool. When the amount of debris in the tool magazine 202 increases, the risk of fire will increase. Therefore, the brush plates 206 are respectively provided on the front and rear sides of the opening for the tool to enter and exit the tool magazine 202. When the tool passes through the opening, the brush plate 206 will sweep across the surface of the tool, and can sweep away the trace amount of debris adhered to the surface of the tool to prevent the debris from mixing into the tool magazine 202. This effectively solves the problem that when the processing material is a flammable material (such as aluminum alloy), there is a risk of the debris being ignited by the flash combustion phenomenon and causing a fire, which poses a certain safety hazard.
