Because after the forming cutter 23 is replaced differently, the forming part 231 of the forming cutter 23 may be pressed on the die holder 1 at the edge of the blanking port 101 in the punching process, and therefore the movable frame 21 needs to be adjustable to avoid the edge position of the blanking port 101. Specifically, as shown in fig. 4 and 5, the die holder 1 is provided with slide rails 12 at both ends of the blanking opening 101, the bottom of both ends of the movable frame 21 is provided with slide blocks 13, and the two slide blocks 13 are respectively connected to the two slide rails 12 in an adaptive manner to slide, so that the movable frame 21 linearly slides relative to the blanking opening 101, thereby adjusting the position of the forming cutter 23.

With continued reference to fig. 4 and 5, the adjustment assembly 3 includes a first fixed seat 31, a second fixed seat adjustment spring 33, and an adjustment screw 34. The first fixing seat 31 and the second fixing seat 32 are fixed on the die holder 1, and the first fixing seat 31 and the second fixing seat 32 are respectively located at two ends of the moving direction of the moving frame 21, namely, two ends of the sliding rail 12. The adjusting spring 33 is connected between the first fixed seat 31 and the movable frame 21, and the elastic force of the adjusting spring 33 pushes the movable frame 21 against the second fixed seat 32. The second fixed seat 32 is in threaded connection with the adjusting screw 34, the adjusting screw 34 abuts against one side of the movable frame 21, which faces away from the adjusting spring 33, and the adjusting spring 33 and the adjusting screw 34 respectively abut against two sides of the movable frame 21, so that the movable frame 21 can be fixed on the die holder 1. When needing to adjust when removing the position of frame 21, through rotating adjusting screw 34, make adjusting screw 34 press to remove frame 21 or keep away from remove frame 21, thereby the drive remove frame 21 relatively the blanking mouth 101 removes, so that shaping cutter 23 can move to being located in the vertical scope of blanking mouth 101, avoid shaping cutter 23 to die-cut the in-process downwards to press on the surface of die holder 1. Furthermore, the adjusting components 3 are arranged on both sides of the moving frame 21, and the moving frame 21 can be more stably and straightly fixed on the die holder 1 by the limitation of the two adjusting components 3.

As shown in fig. 6, the positioning assembly 4 includes a positioning plate 43, a positioning screw 42 and a positioning seat 41, the positioning seat 41 is fixed on the die holder 1, and the positioning seat 41 is located on a side of the blanking port 101 away from the forming cutter 23. A threaded hole (not shown in the drawings) is formed in the positioning seat 41, the positioning screw 42 penetrates through the threaded hole, so that the positioning screw 42 is in threaded connection with the positioning seat 41, and the positioning piece 43 is fixed at one end of the positioning screw 42 close to the forming cutter 23. Furthermore, a first hand wheel 44 is fixed at one end of the positioning screw 42 far away from the positioning plate 43. During operation, the first hand wheel 44 can be rotated to rotate the positioning screw 42, so as to drive the positioning piece 43 to spirally advance or retreat relative to the positioning seat 41, i.e. to adjust the distance between the positioning piece 43 and the forming cutter 23, when the steel pipe 6 is punched, the end part of the steel pipe 6 pushed by the steel pipe 6 is pressed against the positioning piece 43, which is equivalent to the positioning piece 43 blocking the steel pipe 6 to be punched, and then after the steel pipe 6 is punched by the forming cutter 23, the punching of the steel pipe 6 with the specified length can be realized. Furthermore, the positioning screw 42 may be further connected with a fixing nut 45 through a thread, after the distance adjustment of the positioning piece 43 is completed, the fixing nut 45 is rotated to be tightly clamped on the side surface of the positioning seat 41, so that the positioning screw 42 is completely fixed on the positioning seat 41 and cannot rotate, and thus the stability of the position of the positioning piece 43 relative to the forming cutter 23 can be improved.

As shown in fig. 8, the limiting assembly 5 includes a limiting seat 51 and a limiting screw 52, a penetrating limiting groove 102 is provided on the die holder 1, the limiting groove 102 is located on one side of the blanking port 101, and two ends of the limiting groove 102 of the die holder 1 are connected to the limiting seat 51. Referring to fig. 7 again, the structure of the limiting seat 51 is sequentially provided with a limiting plate 511, a limiting block 512 and a nut support 513 from top to bottom, the limiting block 512 is embedded in the limiting groove 102 in a sliding manner, so that the limiting plate 511 and the nut support 513 are respectively located at the upper end and the lower end of the die holder 1. Bearing seats 53 are fixed on the bottom surface of the die holder 1 outside the two ends of the limiting groove 102, and the two ends of the limiting screw 52 are fixed on the two bearing seats 53, so that the limiting screw 52 is connected to the bottom of the die holder 1 to rotate. Meanwhile, the end faces of the two ends of the limiting screw rod 52 are threads with opposite directions, and the two ends of the limiting screw rod 52 are respectively in threaded connection with the nut supports 513 of the limiting seats 51 connected to the two ends of the limiting groove 102, so that the limiting screw rod 52 can drive the two limiting plates 511 to move towards the center of the die holder 1 or to move towards the two sides of the die holder 1 simultaneously when rotating.

Furthermore, one end of the limiting screw rod 52 extends out of the die holder 1, and a second wheel 54 is fixedly connected to one end of the limiting screw rod 52 extending out of the die holder 1. When the distance between the two limiting plates 511 of the two limiting seats 51 needs to be adjusted, the second wheel 54 can be rotated to rotate the limiting screw 52, so as to drive the two limiting plates 511 of the two limiting seats to move, and after the two limiting plates 511 move to a position where a gap formed between the two limiting plates 511 is slightly larger than the outer size of the steel pipe 6 to be punched, the gap is formed.

Furthermore, the utility model discloses still can dispose one set of control system, this control system can be the PLC controller, is used for control the piston rod 221 of driving cylinder 22 is flexible, makes the utility model discloses form continuous die-cut action in an orderly manner, concrete mode of operation is as follows:

s1: when the steel pipe 6 is punched, the steel pipe 6 to be punched passes through the gap between the two limiting plates 511, so that the two limiting plates 511 limit the steel pipe 6, the steel pipe 6 is prevented from swinging left and right relative to the forming cutter 23, namely the steel pipe 6 is positioned, and then the steel pipe 6 is pushed to the positioning piece 43 after the adjustment is completed;

s2: controlling the piston rod 221 of the driving cylinder 22 to descend to enable the forming cutter 23 to descend to cut the steel pipe 6, and the cut steel pipe 6 falls into the blanking hopper 11 from the blanking port 101 at the moment;

s3: repeating the step S1, pushing the steel pipe 6 to be blanked again until the end of the steel pipe 6 abuts on the positioning piece 43, and repeating the step S2 again, so as to continuously blank the steel pipe 6 with the required length and end structure.

To sum up, the utility model discloses a die-cut mould is removable shaping cutter 23 to in need and die-cut corresponding notched steel pipe need not secondary operation, be favorable to improving production efficiency, simultaneously according to shaping cutter 23 and cut the incision that forms and compare in traditional modes such as polishing, have higher precision, can match the steel pipe that is connected and avoid the butt joint to have the gap, be favorable to improving the holistic aesthetic measure of framework to and mechanism intensity.
