[0022] In this embodiment, the pulling mechanism 10 includes a pull rod 13 , two ends of the pull rod 13 are rotatably connected to two rotating shafts 12 , and the two rotating shafts 12 are rotatably connected to two fixing blocks 11 .

[0023] Both ends of the two tie rods 13 are connected to the two fixed blocks 11 through the rotating shaft 12, so that the two tie rods 13 can rotate when the sleeve 5 and the two stamping slide blocks 6 produce relative displacement to adapt to different position angles between the two stamping slide blocks 6 and the sleeve 5.

[0024] In this embodiment, circular holes are formed at both ends of the pull rod 13 , and the two rotating shafts 12 respectively penetrate the circular holes of the pull rod 13 along the axes of the two circular holes of the pull rod 13 .

[0025] The four rotating shafts 12 pass through the circular holes at both ends of the two tie rods 13 respectively, and play the role of fixing the two ends of the two tie rods 13 on the shaft sleeve 5 and the two stamping slide blocks 6 respectively when the two tie rods 13 rotate.

[0026] In this embodiment, the two fixing blocks 11 at one end of the two pull rods 13 are respectively fixedly connected to two sides of the sleeve 5, and the two fixing blocks 11 at the other end of the two pull rods 13 are respectively fixedly connected to the rear of the two stamping slides 6.

[0027] Fixed blocks 11 are provided on both sides of the sleeve 5 and at the rear of the two stamping slide blocks 6 , and are connected via a plurality of rotating shafts 12 and pull rods 13 , so that a linkage effect can be generated between the sleeve 5 and the two stamping slide blocks 6 .

[0028] In this embodiment, two guide rails 7 are also fixedly installed at the bottom of the two stamping slides 6, and sliding grooves are opened on both sides of the top of the base 1 and the bottom of the upper mold 8, and the sliding grooves of the base 1 and the upper mold 8 cooperate with the two guide rails 7 on the two stamping slides 6.

[0029] Guide rails 7 are provided on one side and the bottom of the two stamping slide blocks 6 , so that the two stamping slide blocks 6 can move left and right on the base 1 under the action of the upper die 8 .

[0030] In this embodiment, the sleeve 5 is slidably connected to the fixed shaft 3 , and the inner diameter of the sleeve 5 matches the outer diameter of the fixed shaft 3 .

[0031] The inner diameter of the sleeve 5 matches the outer diameter of the fixed shaft 3 , so that the sleeve 5 can move forward and backward outside the fixed shaft 3 .

[0032] It should be noted that the utility model is an automated metal tube punching device. When in use, the upper die 8 is first raised under the action of the power rod 9 to put the punching device in a standby state. Then, one end of a tube that needs to be punched is aligned with the front of the fixed shaft 3, and the tube is pushed toward the rear of the fixed shaft 3 along the axis of the fixed shaft 3, so that one end of the tube is in contact with the front of the sleeve 5, and the clamping and positioning of the tube is completed. After the tube is placed in the correct position, the power rod 9 provides a downward force to the upper die 8. , so that the upper die 8 is pressed downward. During the process of the upper die 8 being pressed downward, the inclined surface at the bottom of the upper die 8 will apply downward pressure to the inclined surfaces of the two stamping slide blocks 6, and under the action of the inclined contact surface, it is converted into a thrust that makes the two stamping slide blocks 6 converge toward the center, and the two stamping slide blocks 6 will move along a straight line under the limiting action of the two guide rails 7 at the bottom and the slide groove of the base 1, so that the other side of the two stamping slide blocks 6 is pressed into the inside of the pipe, and the pipe is punched and cut to complete the punching.

After the punching is completed, the power rod 9 drives the upper die 8 to move upward, and the two stamping slide blocks 6 also move to both sides under the action of the two guide rails 7 installed on one side and the bottom slide groove of the upper die 8, so that the other side of the two stamping slide blocks 6 is pulled out of the pipe, and The relative distance between the ends of the two pull rods 13 connected to the two stamping slide blocks 6 is increased, thereby shortening the distance between the ends of the two pull rods 13 connected to the bushing 5 and the two stamping slide blocks 6, driving the bushing 5 to move along the axis toward the front of the fixed shaft 3, thereby pushing the pipe to move toward the front of the fixed shaft 3 until the pipe falls off the fixed shaft 3, completing the punching and automatic blanking process of the pipe, eliminating the step of manual material collection, improving processing efficiency, avoiding the safety hazards of manual blanking, and increasing the functionality of the punching device.
