[0081] The workpiece pushing mechanism 11 first pushes the blank into the tool clamping mold 10 on the first section of the workpiece displacement mechanism 4 for clamping, at this time, the tool clamping mold 10 on the second section of the workpiece displacement mechanism 4 is loaded by cooperating with the workpiece temporary storage mechanism 12 and the workpiece pushing mechanism 11, and synchronous loading is realized;

[0083] The working principle of the utility model is: when using, first, the blank is placed on the first section of the workpiece displacement mechanism 4, and is clamped by the tool clamping mold 10 correspondingly arranged on the workpiece displacement mechanism 4, the blank is inserted into the positioning groove between the two symmetrical groove molds 103, the swing clamping seat 102 is swung slightly by the clamping cylinder, the other end of the swing clamping seat 102 drives one of the groove molds 103 to move to the other groove mold 103, the blank is clamped by extrusion between the two symmetrical groove molds 103, the blank is moved by the tool clamping mold 10 through the screw thread cooperation between the threaded drive rod 44 and the sliding support 43, first, the horizontal groove is cut on the surface of the blank by the horizontal groove cutting mechanism 5, the cutting depth of the cutting piece 56 on the blank is adjusted through the movable connection between the fixing seat 51 and the sliding support 53, the cutting thickness of the cutting piece 56 on the blank is adjusted through the movable connection between the sliding support 53 and the mounting seat 54, the cutting piece 56 is rotated by the transmission rod 55 driven by the driving motor 57, and the cutting piece 56 is rotated when the blank passes to cut it, then the blank passes through the two symmetrical deburring structures 6 to polish the two ends, the horizontal position of the polishing wheel 65 is adjusted through the movable connection between the connecting seat 61 and the hollow support 62, the height of the polishing wheel 65 is adjusted through the movable connection between the sliding seat 63 and the hollow support 62, the polishing wheel 65 is rotated by the small motor 64, and the two ends of the passing blank are polished to remove the burrs generated by cutting at the ends of the blank;

[0084] After the first section is processed, the tool clamping die 10 is just located between the workpiece pushing mechanism 11 and the workpiece temporary storage mechanism 12 on the side of the material conveying mechanism 7. At this time, the blank is located in the same plane as the rectangular ejector rod 115 and the workpiece positioning groove 123. The ejector cylinder 113 drives the rectangular ejector rod 115 to move, and the rectangular ejector rod 115 pushes the blank from the positioning groove on the inner side of the groove die 103 to the workpiece positioning groove 123. Then the lifting cylinder 76 drives the pneumatic clamping jaw 77 to move downward. At this time, the mechanical jaws of the pneumatic clamping jaw 77 are opened on both sides of the clamping jaw taking groove 124. After the mechanical jaws are closed, the blank is clamped. Then, through the thread cooperation between the drive screw 73 and the moving slider 75, the moving slider 75 drives the lifting cylinder 76 and the pneumatic clamping jaw 77 to move to the upper side of the workpiece temporary storage mechanism 12 on the other side at the same time, and places the blank into the workpiece positioning groove 123. Then the ejector cylinder 113 drives the rectangular ejector rod 115 to push the blank in the workpiece positioning groove 123 into the tool clamping die 10 of the second section for clamping. At the same time, the tool clamping die 10 of the first section is re-clamped with a new blank.

[0085] The threaded drive rod 44 and the sliding bracket 43 on the second section cooperate with each other to drive the tool clamping die 10 and the workpiece to move. When the workpiece moves to the side of the protruding stamping structure 9, the horizontal position of the groove punch 97 is adjusted through the movable connection between the supporting frame 91 and the L-shaped moving plate 92. Then, through the sliding cooperation between the side support plate 93 and the sliding plate 94, the groove punch 97 is close to the groove of the blank. Finally, the stamping cylinder 96 drives the groove punch 97 to move downward, and the blank is deformed through the pressure, so that a protrusion corresponding to the groove punch 97 below is stamped out of the groove of the blank. Then the blank continues to move to the side of the vertical groove cutting mechanism 8. The cutting motor 87 drives the double-saw cutting head 86 to rotate through the belt drive in the protective cover 88. Then, through the sliding connection between the rectangular rail seat 81 and the horizontal sliding seat 82, the displacement cylinder 83 drives the horizontal sliding seat 82 to move, so that the double-saw cutting head 86 approaches the end of the blank, and a connecting groove is formed at the other end of the blank. The workpiece displacement mechanism 4 of the second section drives the blank to complete the processing. At this time, the workpiece displacement mechanism 4 of the first section drives the blank to complete the processing of the horizontal groove cutting mechanism 5 and the deburring structure 6. The blank on the workpiece displacement mechanism 4 of the first section is transferred through the cooperation of the material conveying mechanism 7, the workpiece pushing mechanism 11 and the workpiece temporary storage mechanism 12. The blank on the workpiece displacement mechanism 4 of the second section can be directly taken down. The blanks on the workpiece displacement mechanisms 4 of the two sections complete feeding, processing and discharging at the same time. Through the cooperation of the workpiece displacement mechanisms 4 of the two sections, different blanks are processed at the same time in different processing steps, so that the processing time of the blank is shortened, and the interval time between multiple blanks is shortened, the efficiency of the whole processing process is improved, and the whole process is fully automated, without manual operation, reducing the labor intensity.
