In order to achieve the purpose, the utility model adopts the following technical scheme:
the punching mechanism comprises a punching seat and a punching head, wherein the front surface of the punching seat is provided with a horizontal cylindrical groove for the end part of the steel pipe to extend into, and the upper end surface and the lower end surface of the punching seat are provided with through punching grooves for punching the end part of the steel pipe to form the arc-shaped notch;
the middle section of the stamping groove is communicated with the end part of the columnar groove, and the stamping groove and the columnar groove are vertically distributed;
the stamping head comprises a cutter holder and a cutter head in a semicircular structure, and the cutter head is arranged on the front surface of the cutter holder;
the punching groove consists of a vertical sliding groove and an arc-shaped groove, and the arc-shaped groove is positioned right in front of the vertical sliding groove;
the tool apron is in sliding fit with the vertical sliding groove, and the tool bit is located in the arc-shaped groove.
Preferably, the transverse section of the vertical chute is a T-shaped structure.
Preferably, the tool bit and the tool apron are integrally formed metal pieces.
Has the advantages that: when the steel pipe punching machine is used, the tool apron is arranged on external lifting equipment, the tool apron is in sliding fit with the vertical sliding groove, the front face of the tool apron close to the bottom is located at the end part of the cylindrical groove, the end part of the steel pipe extends into the cylindrical groove, the end part of the steel pipe is in contact with the front face of the tool apron, the tool bit is located right above the end part of the steel pipe, then the lifting equipment continues to drive the punching head to move downwards, the tool bit punches the side wall of the end part of the steel pipe, two arc-shaped notches which are symmetrically distributed up and down are punched at the end part of the steel pipe, and leftover materials generated by punching fall from the lower end of the punching groove.
The steel pipe punching device is simple in structure, improves punching efficiency and punching quality when the arc-shaped notch at the end part of the steel pipe is punched, and is convenient for blanking leftover materials generated by punching.
