By providing the tip structure at the front end of the square hole punch, the punching process can be facilitated, and by providing the circular arc surface at the front end of the tip structure, the tip can be prevented from being damaged during the punching process, thereby protecting the punch and extending the service life of the punch.
[0007] Furthermore, in order to facilitate replacement of the punching bottom die, the punching bottom die is detachably connected to the punching die frame.
[0008] Furthermore, the punching bottom die is cylindrical, and the punching bottom die cooperates with the circular hole provided at the lower end of the punching die frame, and a stop screw is provided between the punching bottom die and the punching die frame.
[0009] Furthermore, slide grooves are provided on both sides of the lower portion of the punching die frame. The slide grooves provided on both sides of the punching die frame are used to cooperate with the guide rails, so as to facilitate the use of the die and the punching processing equipment.
[0010] Furthermore, a threaded hole is provided at the front portion of the lower end of the punching die frame. The threaded hole is used to connect a pull rod, so that the die can be dragged and moved by the pull rod.
[0011] The beneficial effects of the present invention are: the present invention has a simple structure, can realize punching on the back of angle steel bars, overcomes the defect that the existing angle steel punching die cannot punch on the back of angle steel bars, can improve the adaptability of the angle steel processing production line, and improves the production efficiency of the production line.

[0025] The present invention will be further described below by way of non-limiting embodiments and in conjunction with the accompanying drawings:
[0026] As shown in the accompanying drawings, a die for punching holes in the back of angle steel bars comprises a punching die frame 1, a punch rod 2, a punch 3 connected to the lower end of the punch rod 2, and a punching die 5. The punching die frame 1 is C-shaped, with a punch rod hole provided at the upper end. The punch rod 2 is movably disposed up and down within the punch rod hole of the punching die frame 1. The punching die 5 is disposed at the lower end of the punching die frame 1 corresponding to the punch rod 2. The upper end of the punching die 5 is V-shaped and can mate with an angle steel workpiece 4 with its opening facing upward. A discharge port 8 is provided at the lower end of the punching die frame 1 corresponding to the punching die 5.
[0027] In this embodiment, the punch 3 is a square hole punch that can be used to punch square holes. To facilitate punching, the front end of the punch 3 is a V-shaped tip structure 3-1. To prevent damage to the tip during the punching process, the front end of the tip structure 3-1 is preferably an arc surface.
[0028] To facilitate mold replacement, the punching die 5 is preferably detachably connected to the punching die frame 1. More preferably, the punching die 5 is cylindrical and fits into the circular hole provided at the lower end of the punching die frame 1. A stop screw 6 is provided between the punching die 5 and the punching die frame 1 for stopping the punching die 5.
[0029] In order to facilitate the cooperation with the angle steel punching equipment, it is preferred to provide slide grooves 9 on both sides of the lower part of the punching die frame 1. The slide grooves 9 can slide with the guide rails provided on the angle steel punching equipment to facilitate the movement of the die and the use of the punching processing equipment. In order to facilitate the movement of the die, a threaded hole is also provided at the front of the lower end of the punching die frame 1. The threaded hole is used to connect with the pull rod 7. The power mechanism can drag the die to move through the pull rod 7.
[0030] When using the present invention to punch angle steel, the angle steel workpiece 4 is placed with its opening facing upward on the V-shaped upper end of the punching die 5. The punching mechanism drives the punch rod 2 and the punch 3 to punch the ribs of the angle steel workpiece 4. The punched material is discharged from the discharge port 8 at the lower end of the punching die frame 1.
[0031] The utility model has a simple structure and can realize punching holes on the back of angle steel bars. It can overcome the defect that the existing angle steel punching mold cannot punch holes on the back of angle steel bars, and can improve the adaptability of the angle steel processing production line and improve the production efficiency of the production line.
[0032] The other parts of this embodiment are all existing technologies and will not be described in detail here.
