[0035] The punch assembly 9 comprises a fixed punch 10 fixedly installed on the bottom of the mounting plate 4 by bolts, which is in the shape of a long strip extending horizontally and has a V-shaped cross section. When the punch assembly 9 moves downward, the plate material is punched into the bottom of the punching groove 3 by the lower end of the fixed punch 10, and the plate material forms the bending position of the angle steel at the position corresponding to the lower end of the fixed punch 10.

[0036] Two movable punches 11 are symmetrically distributed on the front and rear sides of the fixed punch 10, which are in the shape of a long strip extending in the same direction as the fixed punch 10 and have a triangular cross section with the tip pointing downward. The two movable punches 11 are provided with punching surfaces 12 on the sides away from each other, and the two punching surfaces 12 are in the shape of a V. When the lower end of the fixed punch 10 punches the plate material into the bottom of the punching groove 3, the punching surfaces 12 on the two movable punches 11 cooperate with the inner wall of the punching groove 3 to extrude the two side walls of the angle steel, so that the angle steel is bent in place.

[0037] As shown in Figure 2 , the bottom of the mounting plate 4 at the left and right ends of the punch assembly 9 is respectively provided with a mounting box 13 fixedly installed by bolts, and the left and right ends of the movable punch 11 are respectively provided with a mounting shaft 14 extending along the length direction thereof, one end of the mounting shaft 14 extending into the corresponding mounting box 13 and being rotatably installed with a mounting bracket 15, as shown in Figure 4 , the mounting bracket 15 is in the shape of an L, and the mounting bracket 15 is provided with a plate block one 16 and a plate block two 17 perpendicular to each other, and the mounting shaft 14 is rotatably installed on the plate block one 16 through a bearing; the mounting box 13 is provided with a sliding rod 18 fixedly installed by bolts, which extends horizontally in the length direction perpendicular to the punch assembly 9, and the corresponding two plate block twos 17 are slidingly installed on the sliding rod 18.

The cylinder body of the adjusting cylinder 19 is installed on the outer wall of the mounting box 13 by bolts, the piston rod of the adjusting cylinder 19 extends along the length direction of the sliding rod 18 and extends into the mounting box 13, and the piston rod of the adjusting cylinder 19 is fixedly connected to the corresponding plate block two 17 by bolts; the side wall of the mounting box 13 close to the punch assembly 9 is provided with two strip-shaped holes 20 for the mounting shaft 14 to pass through, and the mounting bracket 15 slides along the sliding rod 18 to drive the mounting shaft 14 to move along the corresponding strip-shaped hole 20.

[0039] A worm 21 is rotatably mounted on the second plate 17 of the mounting frame 15 through a bearing. The worm 21 is arranged parallel to the slide rod 18, and a worm wheel 22 meshing with the worm 21 is fixedly mounted on the end of the corresponding mounting shaft 14. The worm wheel 22 and the mounting shaft 14 can be driven to rotate by the worm 21, thereby adjusting the angle of the movable punch 11; the spiral teeth of the two worms 21 located in the same mounting box 13 are arranged in opposite directions, and the mounting box 13 is provided with an adjustment component for driving the two worms 21 to rotate synchronously.

[0040] During use, the adjustment assembly drives the two worms 21 to rotate synchronously, and the worms 21 drive the corresponding movable punches 11 to rotate a certain angle through the worm gear 22, thereby adjusting the angle between the punching surfaces 12 on the two movable punches 11 to bend the angle steel to different angles. Because the helical teeth of the two worms 21 are arranged in opposite directions, the two movable punches 11 rotate in opposite directions, thereby ensuring that the two movable punches 11 always maintain a symmetrical state after the angle changes.

[0041] The adjustment assembly includes a drive shaft 23 rotatably mounted in the mounting box 13 via a bearing. The drive shaft 23 is coaxially arranged with the two worms 21. Figure 5 As shown, the worm 21 is provided with a guide hole 24 extending along its axial direction, and the guide hole 24 is slidably sleeved on the outer wall of the drive shaft 23; in order to prevent the worm 21 from deflecting relative to the drive shaft 23, a protrusion 25 is integrally formed on the inner wall of the guide hole 24, and the outer wall of the drive shaft 23 is provided with a guide groove 26 extending along its length direction. The protrusion 25 is slidably installed in the guide groove 26, so that the worm 21 can move back and forth with the mounting frame 15; a motor 27 for driving the drive shaft 23 to rotate is also installed on one side of the mounting box 13 by bolts, and one end of the drive shaft 23 is connected to the motor shaft of the motor 27 through a coupling, and the drive shaft 23 is driven to rotate by the motor 27, and then the drive shaft 23 drives the two worms 21 to rotate synchronously, thereby adjusting the angles of the two movable punches 11.

[0042] A V-shaped mounting groove 28 is provided on the top of the lower die base 2. The mounting groove 28 is in the shape of a transversely extending long strip. Pads 29 are detachably mounted on the inclined front and rear side walls of the mounting groove 28. A V-shaped stamping groove 3 is provided between the two pads 29.

[0043] During use, the angle of the angle steel can be bent according to the needs, and different types of pads 29 can be installed in the installation groove 28 to adjust the angle of the stamping groove 3 between the two pads 29; then the motor 27 drives the drive shaft 23 to rotate, and the angle of the two movable punches 11 is adjusted so that the angle between the stamping surfaces 12 on the two movable punches 11 is consistent with the angle of the stamping groove 3; then the two mounting frames 15 are driven to move closer to or away from each other through the synchronous extension and contraction of the front and rear two adjusting cylinders 19, and then the mounting frames 15 drive the two movable punches 11 closer to or away from each other, so that when the lower end of the fixed punch 10 moves to the bottom of the stamping groove 3, the stamping surfaces 12 on the two movable punches 11 can fit tightly against the front and rear side walls of the stamping groove 3. After completing the above adjustments, the plate is placed on the top of the lower die base 2, and then the angle steel can be stamped and bent.

[0044] like Figures 6 to 8 As shown, in order to facilitate the disassembly and assembly of the pad 29, a slide groove 30 is respectively provided on the front and rear side walls of the mounting groove 28. The cross-section of the slide groove 30 is T-shaped, and the slide groove 30 extends along the inclined direction of the side wall of the mounting groove 28. A slide bar 31 matching the slide groove 30 is welded on the pad 29; in addition, a limiting protrusion 32 is provided at the bottom of the mounting groove 28. The limiting protrusion 32 is a triangle extending along the length direction of the mounting groove 28, and the front and rear sides of the limiting protrusion 32 are respectively provided with limiting surfaces for supporting the lower end of the pad 29.

[0045] The lower die base 2 is provided with mounting holes 33 on the front and rear sides, respectively. The mounting holes 33 extend horizontally from front to back in a direction perpendicular to the mounting slot 28, and one end of the mounting hole 33 is connected to the mounting slot 28. A latch 34 is movably mounted in the mounting hole 33, and the pad 29 is provided with a slot 35 for inserting the latch 34 on the corresponding side. When installing the pad 29, the slide 31 on the pad 29 is inserted into the slide groove 30 on the side wall of the mounting slot 28, and then the pad 29 is slid along the slide groove 30 until the lower end of the pad 29 abuts the limit surface on the limit protrusion 32. The pad 29 is installed in place, and the slot 35 on the pad 29 is moved to align with the corresponding mounting hole 33. Then, the latch 34 is slid along the mounting hole 33 so that one end is inserted into the slot 35, thereby restricting the slide 31 from sliding along the slide groove 30 and preventing the pad 29 from loosening and falling off.

[0046] In order to prevent the pin 34 from accidentally disengaging from the slot 35, a bracket 36 is fixedly installed on the outer wall of the lower mold base 2 opposite to one end of the mounting hole 33. The bracket 36 is U-shaped with the mouth facing the mounting hole 33. A baffle 37 is welded on the pin 34 between the bracket 36 and the outer wall of the lower mold base 2. A spring 38 is sleeved on the pin 34 between the baffle 37 and the bracket 36. One end of the spring 38 abuts the bracket 36 and the other end abuts the baffle 37. The spring 38 gives the pin 34 a push toward the slot 35 to prevent the pin 34 from accidentally disengaging from the slot 35.

[0047] The end of the latch 34 away from the slot 35 extends outside the lower die seat 2 and outside the support 36 and is connected with a pull ring 39. By pulling the pull ring 39, the latch 34 is caused to disengage from the slot 35, and then the cushion block 29 can be removed from the installation slot 28 for replacement.
