The punching mechanism 2 comprises a positioning plate 21 fixed to the vertical body of the frame 1, the positioning plate 21 is arranged horizontally, and a vertical reinforcing plate 22 is fixed to the frame 1 below the positioning plate 21, and the upper end of the reinforcing plate 22 is fixed to the lower surface of the positioning plate 21. A punching cylinder 23 is installed on the frame 1 above the positioning plate 21, and an upper mold 24 is fixed on the output shaft of the punching cylinder 23. A lower mold 25 is fixed on the frame 1 below the positioning plate 21, so that the positioning plate 21 and the reinforcing plate 22 form a right-angle structure, and a distance is left between the lower surface of the positioning plate 21 and the upper surface of the lower mold 25 for the angle steel to pass through, and at the same time, a distance is left between the side wall of the reinforcing plate 22 and the side wall of the lower mold 25 for the angle steel to pass through, so that the angle steel can smoothly pass through the L-shaped space formed by the positioning plate 21, the reinforcing plate 22 and the lower mold 25.

[0026] The upper die 24 and the lower die 25 are arranged in a matching manner. In this embodiment, the upper die 24 is provided with two punches, and the lower die 25 is provided with two punch holes. The punches of the upper die 24 can be inserted through the positioning plate 21 and inserted into the punch holes of the lower die 25. At the same time, the punch holes of the lower die 25 are opened longitudinally. In other embodiments, the upper die 24 and the lower die 25 with the appropriate number of punch holes can be selected according to the number of punch holes required.

[0027] Reference Figure 3 and Figure 4The shearing mechanism 3 includes a mounting plate 31 vertically fixed to the discharge end of the frame 1. The mounting plate 31 is composed of two vertical plates fixed by a plurality of bolts, and a mounting space is left between the two vertical plates. A shearing movable knife 32 is rotatably connected in the mounting plate 31 through a bearing. A shearing fixed knife 33 is fixed to the side wall of the mounting plate 31 below the shearing movable knife 32. At the same time, the shearing movable knife 32 and the shearing fixed knife 33 are not in the same vertical plane. The shearing movable knife 32 is arranged on the inner wall of the mounting plate 31 away from the frame 1, and the shearing fixed knife 33 is arranged on the inner wall of the mounting plate 31 close to the frame 1. A mounting opening 311 is opened horizontally through the upper end of the mounting plate 31. A shearing cylinder 34 is hinged on the inner wall of the upper side of the mounting opening 311. One end of the shearing movable knife 32 is located in the mounting opening 311. The output shaft of the shearing cylinder 34 faces downward and is hinged to one end of the shearing movable knife 32. At the same time, a shearing opening 35 for angle steel to pass through is opened horizontally through the mounting plate 31.

[0028] Reference Figure 4 , wherein the edge of the shearing movable knife 32 facing the shearing fixed knife 33 is set at an L-shaped right angle. In this embodiment, the shearing movable knife 32 is set in an L-shaped manner, and the shearing fixed knife 33 is set at an L-shaped right angle towards the edge of the shearing movable knife 32. In this embodiment, the shearing fixed knife 33 is set in a rectangular shape. In the initial state, an L-shaped space for the angle steel to pass through is formed between the shearing fixed knife 33 and the shearing movable knife 32, so that one end of the shearing movable knife 32 is driven to rotate downward by the shearing cylinder 34, and the angle steel is sheared by the shearing force between the shearing movable knife 32 and the shearing fixed knife 33, so that the cut angle steel falls from the shearing opening 35.

[0029] Reference Figure 3 In order to facilitate the adjustment of the shearing length of the angle steel, a horizontal extension plate 4 is welded to the outer wall of the mounting plate 31 away from the frame 1, and a plurality of limit blocks 41 are hinged on the upper surface of the extension plate 4. The limit blocks 41 are arranged along the feeding direction of the angle steel, and the limit blocks 41 are arranged in an L-shape, so that the end of the limit block 41 can abut against the end of the angle steel extending from the shearing opening 35, and then the limit block 41 at a suitable position can be selected according to the required shearing length to abut the end of the angle steel.

[0030] Reference Figure 1 and Figure 2, an auxiliary frame 5 for assisting the feeding of angle steel is provided on one side of the feeding end of the frame 1, and the auxiliary frame 5 is rotatably connected to a plurality of auxiliary wheels 51 through a bearing, and the plurality of auxiliary wheels 51 are arranged and distributed along the feeding direction of the angle steel. The auxiliary frame 5 is located below the auxiliary wheel 51 and is rotatably connected to a plurality of guide wheels 52, and the plurality of guide wheels 52 are arranged along the feeding direction of the angle steel, and the cross section of the guide wheel 52 is V-shaped. In this way, the right-angled side wall of the angle steel can be abutted against the auxiliary wheel 51, and at the same time, the side edge of the angle steel can abut against the V-shaped groove of the guide wheel 52. The operator can push the angle steel to feed, and with the cooperation of the auxiliary wheel 51 and the guide wheel 52, the angle steel can more smoothly enter the L-shaped space formed by the positioning plate 21, the reinforcing plate 22 and the lower die 25 to perform the punching operation.

[0031] Reference Figure 1 and Figure 2 In order to improve the feeding efficiency, a placement rack 6 for placing the angle steels to be processed is fixed on one side of the auxiliary rack 5 close to the auxiliary wheel 51 along its width direction, so that the operator can place a certain number of angle steels to be processed on the placement rack 6 in advance, which is convenient for the operator to take and feed.

[0032] Reference Figure 1 Since a lot of waste will be generated during the punching process, in order to facilitate collection and cleaning, the frame 1 is provided with a feed opening (not marked in the figure) below the lower die 25, and the feed opening is connected to the punching hole of the lower die 25. It should be noted that the size of the feed opening is smaller than that of the lower die 25. The frame 1 is fixed with an inclined feed plate 7 below the feed opening, and a collection bucket 8 for collecting waste is placed below the feed plate 7, so that the waste punched out can slide along the feed plate 7 into the collection bucket 8 for easy cleaning.
