A moving block 2 17 is arranged on the other end of the threaded rod 13, a height adjustment rod 2 18 is installed through the center of the moving block 2 17, and a moving frame 2 16 is sleeved on the outer side of the moving block 2 17.

In this embodiment, the upper mold 2 is fixed inside the upper mold base 3 by fasteners, and the movement of the upper mold 2 is controlled by the lifting and lowering of the stamping mechanism 4. The material enters between the upper mold 2 and the lower mold 1 from the left side of the mold and fits the lower mold 1, and passes through the bottom of the threaded rod 13. After the material is fixed, stamping can begin. The stamping mechanism 4 drives the upper mold 2 and the lower mold 1 to fit together to complete the stamping. After lifting, the micro motor 15 is started, driving the threaded rod 13 to rotate, and the threads on the threaded rod 13 are engaged with the threads in the threaded hole passing through the center of the tool holder 14, thereby driving the tool holder 14 to move on the threaded rod 13. The blade at the bottom of the tool holder 14 contacts the material to complete the cutting, which is convenient for the operator to directly take away the finished material. The lateral adjustment rod 9 is rotated and inserted into the bottom of the movable frame 10 inside the lateral adjustment mechanism 8. The thread of the lateral adjustment rod 9 is engaged with the thread on the threaded hole at the bottom of the movable frame 10 to push the movable frame 10 to move forward or backward in the lateral adjustment mechanism 8. The movable frame 10 drives the movable block 11 to move through the height adjustment rod 12, thereby driving the threaded rod 13 and the knife seat 14 on the threaded rod 13 to move, thereby adjusting the lateral position of the knife seat 14, so that the device can adapt to molds of different sizes to change the cutting position of the device. At the same time, the height adjustment rod 12 and the height adjustment rod 2 18 are rotated, and the threads on the two height adjustment rods are engaged with the threaded holes passing through the tops of the two movable blocks, so that the two movable blocks can move up and down in the corresponding movable frame. The movable block drives the threaded rod 13 to move up and down, thereby changing the vertical distance between the knife seat 14 and the material, so that the device can adapt to the cutting edges of materials of different thicknesses.

Among them, a locking rod 6 is inserted into the outer side of the lower die base 5 .

In this embodiment, the locking rod 6 passes through the threaded hole opened on the side of the lower mold base 5 through the surface thread. The four surfaces around the lower mold base 5 are provided with threaded holes and the locking rod 6 is rotatably installed. The locking rod 6 passes through the lower mold base 5 and is inserted into the hole on the side of the lower mold 1. The lower mold 1 is supported by a total of eight locking rods 6, and the lower mold 1 is fixed by threaded cooperation. Corresponding to lower molds 1 of different sizes, the locking rod 6 can be used to fix them at the center position of the lower mold base 5.

A positioning rod 20 is disposed at the bottom of the threaded rod 13 .

In this embodiment, the positioning rod 20 passes through the tool holder 14 just like the threaded rod 13. Both ends of the positioning rod 20 are fixedly connected to the moving block 11 and the moving block 2 16, and the positioning rod 20 does not rotate. In this way, when the threaded rod 13 rotates, the positioning rod 20 is fixed to ensure that the tool holder 14 does not rotate with the threaded rod 13 due to the thread. The bottom of the tool holder 14 is always facing downward, so that the thread in the threaded hole and the thread on the threaded rod 13 are engaged to push the tool holder 14 to move left or right.

Among them, a moving groove 19 is opened at the top of the back base 7, and a roller is arranged at the bottom of the moving frame 16.

In this embodiment, when the lateral adjustment rod 9 is rotated, the moving frame 10 moves through the threaded rod 13 to drive the moving frame 2 16 to move. Through the friction between the roller and the moving groove 19, the rolling friction of the roller is small, which prevents the moving frame 2 16 from being misaligned when following the moving frame 10, causing the cutting line to be not straight. At the same time, the movement of the roller in the moving groove 19 further limits the misalignment of the moving frame 2 16.

Wherein, a gap is provided on the left side of the upper die seat 3 .

In this embodiment, the notch prevents the upper die seat 3 and the threaded rod 13 from colliding when the upper die 2 and the lower die 1 are fitted together. The base 7 is arranged on the outside of the lower die seat 5. The misalignment of the notch ensures that the upper die seat 3 will never touch the entire trimming structure during the stamping process.

Among them, the blade cuts the stamping material entering the die from the left side.

In this embodiment, the material is pushed from the bottom of the blade into between the lower mold 1 and the upper mold 2, the stamping mechanism 4 drives the upper mold 2 to press the material down, and closes with the lower mold 1 to complete the stamping, and the stamping mechanism 4 lifts the upper mold 2. At this time, the micro motor 15 rotates to drive the threaded rod 13 to rotate, thereby pushing the knife seat 14 to cut on the material, cutting the material to complete the trimming, and the operator takes away the finished product, and the left material continues to be pushed to the surface of the lower mold 1 to continue stamping.

Working principle: first push the material from the left side of the mold into the space between the upper and lower molds and cover the entire lower mold 1. The operator holds the height adjustment rod 12 and the height adjustment rod 2 18 at the same time and rotates them. The thread on the height adjustment rod 12 engages with the threaded hole of the moving block 11, driving the moving block 11 to move up and down. Similarly, the thread on the height adjustment rod 2 18 engages with the threaded hole of the moving block 2 17, driving the moving block 11 to move up and down, and then driving the threaded rod 13 between the moving block 11 and the moving block 2 17 to move up and down, so that the vertical distance between the knife seat 14 on the threaded rod 13 and the material changes, until the blade fits the material, and then rotate the lateral adjustment rod 9, and the thread on the lateral adjustment rod 9 engages with the threaded hole at the bottom of the moving frame 10 to make the moving frame 10 move back and forth on the lateral adjustment rod 9, and the threaded rod 13 is driven by the height adjustment rod 12, and then the moving frame 2 16 is driven to move, because the roller at the bottom of the moving frame 2 16 is on the moving The movable groove 19 rotates, and the friction between the movable frame 2 16 and the base 7 is small, so that the movable frame 2 16 moves with the movable frame 1 10, and the positions of the movable frame 1 10 and the movable frame 2 16 are always kept parallel, and the threaded rod 13 and the mold are kept vertical, so that the cutting knife line is also kept vertical, and the movement of the movable frame 10 and the movable frame 2 16 drives the threaded rod 13, and then drives the knife seat 14 to adjust the longitudinal cutting position on the surface of the material. After the two positions are adjusted, the stamping mechanism 4 is started, and the stamping mechanism 4 drives the upper mold 2 to move downward, fit the lower mold 1, and complete the stamping of the material, then lift the upper mold 2, and the micro motor 15 is started, driving the threaded rod 13 to rotate, and the thread on the threaded rod 13 is engaged with the thread on the central threaded hole of the knife seat 14, so that the knife seat 14 moves on the threaded rod 13, and the material is cut by the blade at the bottom of the knife seat 14 to complete the trimming. The operator takes the finished product away and continues to push the raw material into the stamping process, and the cycle is repeated.
