The debris and impurities generated during the cutting process can be blocked by the protective shell 201 to reduce splashing and facilitate subsequent recycling.

[0034] like Figure 1-Figure 7 As shown, one side of the rotating block 3105 is fixedly connected to a rotating rod, the other end of the rotating rod passes through the mounting plate 3102 and the slide 3101 in sequence and is fixedly connected to a transmission mechanism 3106, the lower end of the surface of the slide 3101 is fixedly connected to a mounting shell 3107 located inside the mounting table 301, the other end of the transmission mechanism 3106 passes through the interior of the mounting shell 3107 and is rotatably connected to the surface of the slide 3101, and the end of the transmission mechanism 3106 away from the mounting plate 3102 is fixedly connected to a second cone wheel 3111.

[0036] The surface of the rotating block 3105 is provided with two symmetrically distributed mounting tubes 3104, the other end of the mounting tube 3104 extends to the inside of the mounting groove, the end of the mounting tube 3104 away from the rotating block 3105 is fixedly connected with a threaded sleeve 3114, the surface of the mounting tube 3104 is provided with a threaded rod 3113, one end of the threaded rod 3113 is threadedly penetrated through the threaded sleeve 3114 and is fixedly connected with an extrusion plate 3115 which is slidably connected to the inner wall of the mounting tube 3104, the side of the extrusion plate 3115 away from the threaded rod 3113 is fixedly connected with a mounting rod 3116, the other end of the mounting rod 3116 penetrates through the mounting tube 3104 and is fixedly connected to the surface of the splint 3112.

[0037] A liquid storage chamber is formed between a side of the extrusion plate 3115 away from the threaded rod 3113 and the interior of the mounting tube 3104 , and the interior of the liquid storage chamber is filled with hydraulic oil.

[0038] Two connecting cavities 3118 are provided inside the mounting plate 3102, and the inner walls of the two connecting cavities 3118 are respectively slidably connected with a first slip ring 3120 and a second slip ring 3119. The surfaces of the first slip ring 3120 and the surfaces of the second slip ring 3119 are both provided with a guide tube 3117, and the other end of the guide tube 3117 is connected to the adjacent liquid storage cavity.

[0039] By rotating the threaded rod 3113, it can gradually pass through the threaded sleeve 3114 and be inserted into the interior of the installation tube 3104. In this process, the extrusion plate 3115 can be driven to move synchronously, thereby driving the installation rod 3116 to adjust the position of the clamping plate 3112 so that it can adapt to the clamping of bars of different specifications. In the process of the movement of the extrusion plate 3115, the hydraulic oil stored in the liquid storage chamber can be squeezed and introduced into the connecting chamber 3118 connected thereto through the guide pipe 3117;

[0041] like Figure 1-Figure 7The auxiliary component 32 shown includes a support frame 3201 fixedly connected to the surface of the mounting platform 301, two symmetrically distributed connecting tubes 3205 are fixedly connected between the inner side of the support frame 3201 and the mounting platform 301, connecting plates 3202 are provided on opposite sides of the two connecting tubes 3205, cleaning blocks 3207 are fixedly connected on opposite sides of the two connecting plates 3202, an adjusting rod 3203 is fixedly connected to the surface of the connecting plate 3202, the other end of the adjusting rod 3203 is slidably connected to the inner wall of the connecting tube 3205, a spring 3204 is fixedly connected to the surface of the adjusting rod 3203, and the other end of the spring 3204 is fixedly connected to the inner wall of the connecting tube 3205.

[0042] The surface of the connecting tube 3205 is connected with a conduit 3206 , and the other ends of the two conduits 3206 are respectively connected with the two connecting cavities 3118 .

[0043] During the adjustment of the splint 3112, the hydraulic oil injected into the connecting cavity 3118 can be introduced into the interior of the connecting cylinder 3205 through the conduit 3206, so that the hydraulic oil can be used to push the adjusting rod 3203 to squeeze the spring 3204. In this process, the position of the connecting plate 3202 can be synchronously adjusted, and the rod can be well cleaned when passing through the cleaning block 3207. The rod will rotate during the movement through the limit assembly 31 to enhance the cleaning effect, so as to facilitate subsequent cutting. After the cutting is completed, the rod can be rotated in the reverse direction during the reverse movement to use the cleaning block 3207 to clean the debris and impurities adhered to its surface.

[0044] like Figure 1-Figure 7 The dust reduction mechanism shown includes a liquid storage tank 2 arranged at the bottom of the workbench 1, the interior of the liquid storage tank 2 is filled with water for dust reduction, a water pump 206 is arranged inside the liquid storage tank 2, the water outlet end of the water pump 206 is connected to a connecting pipe 204, a connecting box 203 is fixedly connected to the surface of the cutting mechanism 202, the other end of the connecting pipe 204 is connected to the connecting box 203, and the bottom of the connecting box 203 is connected to evenly distributed nozzles 207.

[0045] A guide plate 205 is fixedly connected to the inside of the protective shell 201, and a filter screen 209 is fixedly connected to the inner wall of the guide plate 205. A filter chamber is formed between the inner side of the filter screen 209 and the inside of the guide plate 205. A return pipe 208 is connected to the top of the liquid storage tank 2, and the other end of the return pipe 208 is connected to the filter chamber.

[0046] By starting the water pump 206, water can be introduced into the interior of the connecting box 203 through the connecting pipe 204, so that the nozzle 207 can be used to cool and dust the cutting area during the cutting process, thereby reducing the impact of the heat generated during the cutting process on the magnetic core bar material, and at the same time reducing the dust pollution generated during the cutting process. The used dust reduction water can pass through the filter screen 209 along the surface of the guide plate 205 and enter the filter cavity. At the same time, the debris can be intercepted under the action of the filter screen 209, so that the dust reduction water can be used again, thereby reducing the cost of use.

[0047] Working principle: By rotating the threaded rod 3113, it can gradually pass through the threaded sleeve 3114 and be inserted into the interior of the mounting tube 3104. In this process, the extrusion plate 3115 can be driven to move synchronously, thereby driving the mounting rod 3116 to adjust the position of the splint 3112, so that it can adapt to the clamping of rods of different specifications. In the process of the movement of the extrusion plate 3115, the hydraulic oil stored in the liquid storage chamber can be squeezed and introduced into the connecting chamber 3118 connected thereto through the guide tube 3117. In the process of adjusting the splint 3112, the hydraulic oil injected into the connecting chamber 3118 can be introduced into the interior of the connecting tube 3205 through the conduit 3206, so that the hydraulic oil can push the adjusting rod 3203 to squeeze the spring 3204. In this process, the synchronous adjustment of the position of the connecting plate 3202 can be realized, and when the rod passes through the cleaning block 3207, The rod material can be well cleaned, and the rod material will rotate during the movement through the limit assembly 31 to enhance the cleaning effect, so as to facilitate subsequent cutting, and after the cutting is completed, it can rotate in the reverse direction during the reverse movement to use the cleaning block 3207 to clean the debris and impurities adhering to its surface, and in the cutting process, by starting the water pump 206, water can be introduced into the interior of the connecting box 203 through the connecting pipe 204, so that the nozzle 207 can be used to cool and reduce dust at the cutting site during the cutting process, reducing the influence of the heat generated during the cutting process on the magnetic core rod material, and at the same time, it can reduce the dust pollution generated during the cutting process. The dust reduction water after use can pass through the filter screen 209 along the surface of the guide plate 205 and enter the filter cavity. At the same time, under the action of the filter screen 209, the debris can be intercepted, so that the dust reduction water can be used again, reducing the use cost.
