[0016] Preferably, the processing method of the adjustable wire cutting machine frame for automatically recovering waste chips specifically comprises the following steps:

[0017] Step 1: When performing wire cutting on a workpiece, first place the workpiece between two clamping racks, then control the driving screw to rotate clockwise to allow the two clamping racks to approach the two sides of the workpiece, then rotate the adjusting screw clockwise, and the upper and lower first clamping plates clamp the upper and lower surfaces of the workpiece, and then control the positioning screw to allow the second clamping plate to approach one side of the workpiece, use the second clamping plate and one side of the inner wall of the clamping rack to clamp and position the front and rear sides of the workpiece, cooperate with the two first clamping plates to clamp and position the upper and lower sides of the workpiece, and at the same time, the opposite side of the two clamping racks clamp and position the left and right sides of the workpiece;

During the cutting process, the low-temperature liquid nitrogen is passed into the upper protective cover through the air guide pipe by the air guide pump, and the low-temperature nitrogen is sprayed to the cutting area of ​​the cutting molybdenum wire and the workpiece by the nozzle inside the upper protective cover, and the surface of the cutting molybdenum wire and the cutting workpiece is cooled by the low-temperature nitrogen;

[0022] 1. In the present invention, the cutting workpiece is stably clamped by a clamping mechanism, and the cutting workpiece is processed by wire cutting in cooperation with a wire-laying mechanism. In addition, the waste chips generated during the wire cutting process are collected and processed by a protective structure on the wire-laying mechanism, so as to avoid the waste chips generated during the wire cutting process from splashing around and polluting the surrounding environment of the processing frame; and in the process of cutting the cutting workpiece by using the wire-laying mechanism, low-temperature nitrogen is used to cool the surface of the cutting molybdenum wire and the cutting workpiece, so as to effectively reduce the surface temperature of the workpiece, reduce the thermal stress and thermal deformation during the cutting process, and improve the cutting quality and accuracy. Moreover, low-temperature nitrogen is a colorless, odorless, and non-toxic gas, which will not pollute the environment during use, and will not generate waste liquid or waste materials that need to be processed. Compared with the cooling method of coolant or water, low-temperature nitrogen can not only reduce the temperature of the workpiece more quickly, but also the evaporated water generated during the cooling process of low-temperature nitrogen will condense on the surface of the workpiece, so that the cutting process remains dry, avoiding the problems of electric sparks and workpiece corrosion caused by moisture, and significantly improving the cutting quality of the workpiece.

[0023] 2. The present invention controls two protective covers to approach each other through the driving ends of the upper and lower second servo electric cylinders, and utilizes the two protective covers to protect the upper and lower surfaces of the cutting workpiece respectively, and to protect the waste chips generated when the molybdenum wire is cut to the workpiece from splashing, thereby preventing the processing waste chips from splashing around and polluting the processing frame and causing health hazards to the processing personnel. After the cutting process of the workpiece is completed, the processing waste chips are automatically recovered by the upper and lower protective covers, thereby realizing the recycling and reuse of the processing waste chips and avoiding the waste of processing waste chips.

[0024] 3. In the process of cutting, the present invention uses an air pump to pass low-temperature liquid nitrogen through an air pipe into the upper protective cover, and uses a nozzle inside the upper protective cover to spray low-temperature nitrogen toward the cutting area of ​​the molybdenum wire and the workpiece. The surface of the molybdenum wire and the workpiece is cooled by the low-temperature nitrogen, which effectively reduces the surface temperature of the workpiece, reduces thermal stress and thermal deformation during the cutting process, and improves the cutting quality and accuracy. In addition, the waste chips generated during the cutting process are recovered through the upper and lower protective covers, and the waste chips recovered inside the two protective covers are extracted by the extraction pump inside the extraction box in cooperation with the extraction pipe and the guide sleeve, so as to avoid excessive waste chips accumulating inside the protective cover and affecting the cutting quality of the workpiece.

2. A processing method of the adjustable wire cutting machine frame for automatically recovering waste chips according to claim 1, comprising the following steps: Step 1, when performing wire cutting processing on the workpiece, first place the workpiece between the two clamping frames (16), then control the driving screw (17) to rotate clockwise, so that the two clamping frames (16) approach the two sides of the workpiece, then rotate the adjusting screw (24) clockwise, and the upper and lower first clamping plates (23) clamp the upper and lower surfaces of the workpiece, and then control the positioning screw (27) to make the second clamping plate (25) approach one side of the workpiece, use the second clamping plate (25) and one side of the inner wall of the clamping frame (16) to clamp and position the front and rear sides of the workpiece, cooperate with the two first clamping plates (23) to clamp and position the upper and lower sides of the workpiece, and at the same time, the opposite side of the two clamping frames (16) clamp and position the left and right sides of the workpiece; Step 2: When cutting the workpiece, the two protective covers (7) are controlled to move to the upper and lower surfaces of the workpiece respectively, and then move to one side of the workpiece along with the cutting molybdenum wire (3); Step 3, by controlling the movable frame (6) to approach one side of the workpiece, and then controlling the two protective covers (7) to approach the upper and lower surfaces of the workpiece through the driving end of the second servo electric cylinder (8), the upper and lower protective covers (7) are respectively in contact with the upper and lower surfaces of the workpiece, and the cutting area of ​​the workpiece is sealed by the upper and lower protective covers (7), and then the workpiece is cut by the cutting molybdenum wire (3). During the cutting process, low-temperature liquid nitrogen is introduced into the upper protective cover (7) through the air guide pipe by the air guide pump (14), and the low-temperature nitrogen is sprayed toward the cutting area of ​​the cutting molybdenum wire (3) and the workpiece by the nozzle inside the upper protective cover (7), and the surface of the cutting molybdenum wire and the cutting workpiece is cooled by the low-temperature nitrogen; Step 4: The waste chips generated during the cutting process are recovered through the upper and lower protective covers (7), and the waste chips recovered inside the two protective covers (7) are extracted through the extraction pump inside the extraction box (12) in conjunction with the extraction pipe and the guide sleeve (13).
