Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0022] The following is combined with Figure 1 —5 Further details of this application are provided.

[0023] A punching die for an aluminum bracket comprises a base 1.

[0024] A mounting frame 2 is fixedly arranged on the base 1, a downward pressure cylinder 3 is fixedly arranged on the mounting frame 2, a mounting seat 4 is fixedly arranged on the output shaft of the downward pressure cylinder 3, an offset block 5 is fixedly arranged on the mounting seat 4, and a yielding groove 6 is opened on the offset block 5.

[0025] A mounting platform 7 is fixedly provided on the base 1, and a clamping device 8 and a punching device 9 are provided on the mounting platform 7; a guide rod 10 is fixedly provided on the mounting seat 4, and a guide block 11 corresponding to the guide rod 10 is fixedly provided on the mounting platform 7, and the guide rod 10 is slidably provided in the guide block 11, and four guide rods 10 are provided; a lateral fixing block 12 is fixedly provided on the mounting platform 7, and two lateral fixing blocks 12 are provided.

[0026] The punching device 9 includes a sliding block 13 and a punch rod 14. The sliding block 13 is slidably set on the mounting table 7, and the punch rod 14 is fixedly set on the sliding block 13. There are multiple punch rods 14. A limit block 15 is fixedly set on the mounting table 7. The limit block 15 is provided with a through hole (not shown in the figure). A connecting rod 16 is slidably set in the through hole. One end of the connecting rod 16 is fixedly set on the sliding block 13, and a stopper 17 is fixedly set on the other end of the connecting rod 16. A reset spring 18 is sleeved on the connecting rod 16, and the reset spring 18 is located between the stopper 17 and the limit block 15. Two sliding blocks 13 are provided.

[0027] The clamping device 8 includes a placement block 19, which is slidably set on the mounting table 7. Two placement blocks 19 are provided, and a placement hole (not shown in the figure) is opened on the placement block 19. The placement holes on the two placement blocks 19 are coaxially arranged, and a push-off spring 20 is placed in the two coaxially arranged placement holes; a pressure sheet spring 21 is fixedly set on the placement block 19, and the pressure sheet spring 21 is pressed against the sliding block 13; a clearance hole 22 is opened on the placement block 19, and the punch rod 14 is slidably set in the clearance hole 22.

[0028] The implementation principle of this embodiment is as follows: when punching the aluminum tube, the aluminum tube is placed on the placement block 19, and then the downward pressure cylinder 3 is driven to work; the output shaft of the downward pressure cylinder 3 drives the mounting seat 4 to move downward, so that the offset block 5 moves in the direction of the sliding block 13 until the offset block 5 contacts the sliding block 13; when the mounting seat 4 continues to move downward, the offset block 5 pushes the two sliding blocks 13 to move in the direction of approaching each other, and at the same time, under the action of the stop block 17, the return spring 18 is compressed and deformed; in the process of the two sliding blocks 13 approaching each other, the two placement blocks 19 are acted on by the compression springs 21 installed on both sides of the sliding blocks 13 to move in the direction of approaching each other, and compress the push-off spring 20 in the placement hole; when the two placement blocks 19 are pressed against each other, The aluminum tube is clamped on the two placement blocks 19; the mounting seat 4 continues to move downward, and the offset block 5 continues to push the two sliding blocks 13 to move in the direction of approaching each other. At this time, the pressure plate spring 21 is forced to undergo compression deformation, and the sliding block 13 moves in the direction of approaching the placement block 19. At this time, the punch rod 14 passes through the clearance hole 22 and punches the aluminum tube; after the punching operation is completed, the output shaft of the downward pressure cylinder 3 is driven to rise, and the reset spring 18 drives the two sliding blocks 13 away from each other when it recovers, first making the pressure plate spring 21 gradually recover, and after the punch rod 14 withdraws from the aluminum tube and the clearance hole 22, the push-off spring 20 recovers and pushes the two placement blocks 19 in the direction of moving away from each other, so that the placement block 19 relaxes its clamping of the aluminum tube and the processed aluminum tube can be removed for the next operation.

[0029] After the aluminum tube is placed on the placement block 19, the downward pressure cylinder 3 is driven to work, and the offset block 5 is pressed against the sliding block 13. The linkage effect of each mechanism enables the aluminum tube placed between the two placement blocks 19 to complete the clamping and punching work, and the neatly arranged adjustment holes are formed in one time, which has the advantage of fast processing speed.
