[0009] Compared with the prior art, the present invention has the following beneficial effects:

[0010] 1. When the present invention is used, the present invention is adjusted according to the diameter of the corrugated pipe to be punched as needed, specifically as follows: select a punching inlet pipe of corresponding diameter, and fix the annular connecting plate on the punching inlet pipe to the punching plate by connecting bolts; loosen the first adjusting bolt to move the lower support rod on the first adjusting groove, so that the first concave rotating wheel on the lower support rod is located on the lower end surface of the corrugated pipe, and then tighten the first adjusting bolt to fix the position height of the lower support rod and the first concave rotating wheel on the U-shaped lower support frame; insert the adjusting pin into one of the adjusting pins on the feed positioning push rod The node hole is used to adjust the position of the feed positioning push rod on the rotating connecting head, thereby changing the position of the push plate at the lower end of the feed positioning push rod. When the feed positioning push rod is in the vertical direction, the push plate is located in the groove of the corrugated pipe; by loosening the second adjusting bolt, the upper support rod moves on the second adjusting groove, and the position of the upper support rod on the n-shaped upper support frame is changed, so that the second concave rotating wheel on the upper support rod is located on the upper end surface of the corrugated pipe, and then the second adjusting bolt is tightened to fix the position height of the upper support rod and the second concave rotating wheel on the n-shaped upper support frame, so as to achieve a wide range of application of the corrugated pipe diameter.

[0011] 2. After adjusting the diameter of the corrugated pipe to be punched according to the need, the corrugated pipe to be punched is inserted into the N-shaped upper support frame, the feed positioning plate, the U-shaped lower support frame and the punching plate from right to left in sequence; the second concave rotating wheel on the U-shaped lower support frame is located on the upper end surface of the corrugated pipe; the corrugated pipe passes through the pipe feeding hole on the feed positioning plate, and the pipe feeding hole does not contact the corrugated pipe, and when the feed positioning push rod is located in the vertical direction, the push plate is located at the groove of the corrugated pipe; the first concave rotating wheel on the U-shaped lower support frame is located on the lower end surface of the corrugated pipe; the corrugated pipe passes through the punched holes on the punching plate and enters the pipe.

[0012] 3. Through the operation of the second cylinder, the second cylinder drives the second push rod to extend, and the second push rod drives the upper end of the feed positioning push rod to move leftward via the rotating connector and the latch, and the push plate at the lower end of the feed positioning push rod is located in the groove of the bellows, and the feed positioning push rod rotates counterclockwise around the latch, but the feed positioning push rod rotates to the vertical direction. Under the action of the rotation limit block provided on the upper end face of the left rotating connector of the feed positioning push rod, the feed positioning push rod cannot rotate counterclockwise, and because the push plate is located in the groove of the bellows, the extended second push rod drives the feed positioning push rod to move vertically to the leftward via the rotating connector, the rotating limit block and the latch, and the feed positioning push rod moving vertically to the leftward will move the lower The return spring connected to the right side of the end is stretched, and the lower end of the feed positioning push rod moving vertically to the left drives the push plate to move left, and because the lower end of the push plate is an arc-shaped structure, the push plate is convenient to be located in the groove of the bellows, and the push plate located at the groove of the bellows pushes the bellows to move left, so that the bellows is sent into the punching inlet tube on the punching plate. In the process of the bellows moving to the left, since the second concave rotating wheel on the U-shaped lower supporting frame is located on the upper end surface of the bellows and the first concave rotating wheel on the U-shaped lower supporting frame is located on the lower end surface of the bellows, the second concave rotating wheel and the first concave rotating wheel rotate, reducing the resistance of the bellows to moving left, and the second concave rotating wheels and the first concave rotating wheel can also move The movable bellows plays a limiting role to prevent the bellows from deviating upward or downward; after the bellows moves to the left and is sent into the punching inlet tube on the punching plate, and by adjusting the extension distance of the second push rod, the distance the bellows moves to the left is adjusted, so that the groove of the bellows moving to the left is located on the working surface where 3-6 punching needles are located, and the 3-6 first single-head cylinders on the left side of the punching plate work and extend at the same time, and the 3-6 first single-head cylinders drive the punching needles to extend through the first push rod at the same time, and the punching needles punch holes at the groove of the bellows, and then the 3-6 first single-head cylinders work and shrink at the same time, return to the initial position, and punch a hole in the bellows to form a bellows hole; then the second air cylinder on the feed positioning plate The cylinder contracts when working, and the second cylinder drives the second push rod to contract. The second push rod drives the upper end of the feed positioning push rod to move to the right through the rotating connecting head and the pin. When the pin is located in the adjusting hole, the feed positioning push rod rotates counterclockwise, and the push plate at the lower end of the feed positioning push rod disengages from the groove of the bellows. Under the action of the elastic force of the return spring connected to the right side of the lower end of the feed positioning push rod, the return spring drives the lower end of the feed positioning push rod to move to the right and return to the initial position, and then falls into the new groove of the bellows.
