[0002] Metal cutting is a material removal and forming method in the metal forming process, which still accounts for a large proportion in today's mechanical manufacturing. The tool removes excess metal from the workpiece to be processed and, under the premise of controlling productivity and cost, enables the workpiece to obtain geometric accuracy, dimensional accuracy and surface quality that meet the design and process requirements. The chips or fragments produced by metal cutting need to be crushed and recycled.

[0003] When the existing pulverizer is in use, after the pulverization is completed, it is generally collected directly and enters the next processing step, resulting in the inability to distinguish between qualified products and unqualified products after pulverization. When the metal debris contains debris blocks of unqualified volume, entering the next processing step will cause uneven melting after heating, which will affect the processing effect during recycling and greatly reduce the practicality of the pulverizer.

[0022] Reference Figure 1 , Figure 2 and Figure 3 The metal cutting pulverizer comprises a pulverizing box 1 and a support frame 2. The pulverizing box 1 is mounted on the support frame 2. A feed box 3 is fixed through the top surface of the pulverizing box 1. A feed port 4 is fixed through the bottom surface of the pulverizing box 1. A fan 5 is fixed through the top surface of the feed box 3. A fan with an air outlet downward is arranged inside the fan 5. An air inlet is provided on the top surface of the fan 5. A filter is fixed inside the air inlet. The air outlet at the bottom of the fan 5 is located directly above the pulverizing box 1.

[0023] A separation filter box 6 is provided at the bottom of the discharge port 4, the length inside the separation filter box 6 is equal to the length inside the bottom end of the discharge port 4, the width inside the separation filter box 6 is equal to the width inside the bottom end of the discharge port 4, a handle is fixed to the middle of one end of the separation filter box 6 close to the limit block 9, and a filter screen 7 is fixed to the bottom of the separation filter box 6, support plates 8 are symmetrically provided on both sides of the separation filter box 6, and the tops of the support plates 8 are fixed to the sides of the discharge port 4, and the separation filter box 6 is slidably inserted into the support plates 8 on both sides.

[0024] Specifically, during crushing, the fan inside the fan 5 is turned on, so that the fan runs to blow air downward, so that the fragments can move better toward the crushing blades. At the same time, the crushed debris can quickly pass through the discharge port 4 to the inside of the separation filter box 6, and be filtered through the filter screen 7. After filtering, qualified debris is directly discharged through the filter screen 7, and unqualified debris is collected inside the separation filter box 6.

[0025] As an optimization solution, Figure 3 As shown, the bottom surface of the separation filter box 6 is symmetrically fixed with a limit block 9, and the limit block 9 is located at the outside of the support plate 8 at one end, and a movable limit plate 11 is slidably sleeved on the outside of the limit block 9, and the two movable limit plates 11 are both arranged in a horizontally placed "L" shape, and the distance between the side of the movable limit plate 11 close to the movable side plate 10 and the support plate 8 is equal to the thickness of the limit block 9, and a movable side plate 10 is fixed on the end of the movable limit plate 11 close to the support plate 8, and the two movable side plates 10 are both slidably arranged on the outside of the support plate 8, and a fixed block 12 is slidably sleeved inside the movable side plate 10, and the two fixed blocks 12 are both arranged in a horizontally placed "T" shape, and a sliding groove cooperating with the fixed block 12 is opened inside the movable side plate 10, and the upper and lower ends of the spring 13 are fixed on the side wall of the sliding groove, and the fixed block 12 penetrates to one end of the inner side of the movable side plate 10 and is fixed on the outer surface of the support plate 8, and a spring 13 is fixed between the top surface of the fixed block 12 and the inner top surface of the movable side plate 10.

[0026] Specifically, when it is necessary to clean the unqualified debris inside the separation filter box 6, push the movable side plates 10 on both sides downward so that the movable side plates 10 compress the springs 13. When the movable side plates 10 move downward, they drive the movable limit plates 11 to move downward, so that the limit of the movable limit plates 11 on the limit blocks 9 can be released. After releasing, the separation filter box 6 can be pulled out from the support plate 8 to the limit blocks 9 by pulling the separation filter box 6 from the support plate 8. After pulling it out, pour the unqualified debris into the feed box 3, and then insert the separation filter box 6 into the support plate 8, and loosen the movable side plates 10, so that the movable side plates 10 can pull the movable limit plates 11 to move to the side of the limit blocks 9 under the push of the springs 13.
