[0026] See Figure 1-Figure 3 , Figure 1 This is a structural diagram of the short tube punching equipment for a rotary umbrella in an embodiment. Figure 2 The rotary clamping device, the first punching device and the second punching device in the embodiment are: Figure 3 for Figure 1Enlarged view of part A in the middle. In this example, a rotary umbrella short tube punching device includes a machine 1 and a rotary clamping device 2, a feeding device 3, a first punching device 4, a flipping device 5 and a second punching device 6 arranged on the machine 1. Among them, the rotary clamping device 2 includes a rotary drive mechanism 21, a turntable 22 and a plurality of clamping mechanisms 23. The rotary drive mechanism 21 is arranged at the center of the machine 1, the turntable 22 is driven by the rotary drive mechanism 21, and the clamping mechanisms 23 are arranged circumferentially on the peripheral wall of the turntable 22. The feeding device 3, the first punching device 4, the flipping device 5 and the second punching device 6 are arranged in sequence along the circumference of the turntable 22, and are all opposite to the movement path of the clamping mechanism 23. In this example, the feeding device 3 adopts a vibrating disk.

[0027] During operation, the feeding device 3 transports the short tube to the turntable clamping mechanism 23. The clamping mechanism 23 clamps one end of the short tube and then transports it to the first punching device 4, the flipping device 5 and the second punching device 6 in sequence. During the process, the short tube is always consistent with the radial direction of the turntable 22. When the short tube reaches the first punching device 4, the first punching device 4 punches the upper surface of the short tube. When the short tube reaches the flipping device 5, the flipping device 5 rotates the short tube so that the other surface of the short tube faces upward. When the short tube reaches the second punching device 6, the second punching device 6 punches the upper surface of the rotated short tube, and then the clamping mechanism 23 transports it to the blank area of ​​the machine 1 for unloading, thereby realizing fully automatic stamping of different surfaces of regular hexagonal short tubes, greatly improving production continuity, and thus improving production efficiency.

[0028] See Figure 4 , review Figure 1-Figure 3 , Figure 4 The figure is a schematic diagram of the clamping mechanism structure in the embodiment. Specifically, the clamping mechanism 23 includes a clamping drive 231 and two clamping blocks 232. The clamping drive 231 is fixed to the turntable 22, and the two clamping blocks 232 are mounted on the driving end of the clamping drive 231. The clamping drive 231 drives the two clamping blocks 232 toward or away from each other. In this embodiment, the clamping drive 231 uses parallel pneumatic jaws.

[0029] The sidewalls of each clamping block 232 are provided with a clamping recess 2321. The clamping recesses 2321 of the two clamping blocks 232 face each other. When the two clamping blocks 232 approach each other, a clamping opening 23211 is formed between their clamping recesses 2321. The loading device 3, the first punching device 4, the flipping device 5, and the second punching device 6 are all aligned with the movement path of the clamping openings 23211. That is, when a short tube needs to be clamped, the clamping drive 231 drives the two clamping blocks 231 close to each other, and the clamping openings 23211 formed by their clamping recesses 2321 clamp the two sides of the short tube. In this example, the clamping recess 2321 is a regular hexagon, consistent with the cross-sectional shape of the short tube, preventing the short tube from flipping or deflecting during operation and improving processing stability.

[0030] Review Figure 2-Figure 3 Furthermore, the first punching device 4 includes a first translation mechanism 41 and a punching mechanism 42. The first translation mechanism 41 includes a first translation drive 411 and a first translation plate 412. The first translation drive 411 is provided on the machine 1 along the radial direction of the turntable 22. The first translation plate 412 is driven by the first translation drive 411. The punching mechanism 4 is provided on the first translation plate 412. In this example, the first translation drive 411 is composed of a cylinder, a slider, and a slide rail.

[0031] The punching mechanism 42 includes a die frame 421, a punching drive 422, and a punching head 423. The die frame 421 is mounted on the first translation plate 412, with an overhead 4211 between the die frame 421 and the first translation plate 412. The punching drive 422 is mounted on the top of the die frame 421, with its driving end exposed in the overhead 4211. The punching head 423 is mounted on the driving end of the punching drive 422. When the clamping mechanism 23 delivers the short tube to the punching mechanism 42, the first translation drive 411 drives the first translation plate 412 and drives the die 421 to move toward the clamping mechanism 23, so that the short tube enters the overhead 4211. At this time, the punching head 423 is facing the short tube. Driven by the punching drive 422, the punching head 423 punches a hole toward the upper surface of the short tube. After the punching is completed, the clamping mechanism 23 delivers the short tube to the turning device 5. In this example, the punching drive 422 adopts a gas-liquid booster cylinder.

[0032] Preferably, the first punching device 4 further includes a support mechanism 43, which includes a fixed frame 431 and a support head 432. The fixed frame 431 is fixed on the first translation plate 412 and is located in the overhead 4211. One end of the support head 432 is fixed to the fixed frame 431, and the other end extends toward the rotating clamping device 3 and is aligned with the moving path of the clamping port 23211. The side wall of the support head 432 is provided with a through hole 4321, and the punching head 423 is aligned with the through hole 4231. It is understandable that in the process of the mold frame 421 moving toward the clamping mechanism 23, the support head 432 is inserted into the short tube from one end. When punching, the punching head 423 punches the surface of the short tube and then punches into the through hole 4321. In this way, the support head 432 evenly distributes the force on the short tube to prevent the short tube from being deformed. Preferably, the turntable 22 is provided with a plurality of fixing holes 221, which are arranged on the side wall of the turntable 22 along the circumference of the turntable 22 and are directly opposite to the clamping opening 23211. During operation, the support head 432 passes through the short tube and is inserted into the fixing hole 221, further improving the stability of the support head 432.

[0033] See Figure 5 , review Figure 1 , Figure 5Schematic diagram of the flipping mechanism in the embodiment. Furthermore, the flipping mechanism 5 includes a second translation mechanism 51 and a flipping mechanism 52. The second translation mechanism 51 includes a second translation drive 511 and a translation frame 512. The second translation drive 511 is also mounted on the machine 1 along the radial direction of the turntable 22. The translation frame 512 is mounted on the second translation drive 511. The flipping mechanism 52 is mounted on the translation frame 512 and directly opposite the motion path of the clamping opening 23211. In this embodiment, the second translation drive 511 is also composed of a cylinder, a slide rail, and a slider.

[0034] Specifically, the flip mechanism 52 includes a flip driver 521 and a flip head (not shown). The flip mechanism 521 is mounted on the translation frame 512 and faces the rotary clamping device 2. One end of the flip head (not shown) is mounted on the driving end of the flip driver 521, and the other end is aligned with the motion path of the clamping opening 23211. The flip head (not shown) has a regular hexagonal cross-section. In this example, the flip driver 521 is a servo motor. When the clamping mechanism 23 transports the short tube to a position opposite to the flip head (not shown), the second translation drive 511 drives the translation frame 512 to move toward the clamping mechanism 23, so that the flip head (not shown) is inserted into the short tube from one end of the short tube. At this time, the clamping mechanism 23 releases its grip on the short tube, and the flip drive 521 drives the flip head (not shown) to rotate, thereby driving the short tube to rotate, thereby completing the flipping of the short tube. When the clamping mechanism 23 clamps the short tube again, the second translation mechanism 511 drives the translation frame 512 to reset the flip mechanism 52, and the flip head (not shown) is separated from the short tube. Then, the clamping mechanism 23 transports the short tube to a position opposite to the second punching device 6. In this example, the cross-sectional shape of the support head 432 is consistent with the cross-sectional shape of the flip head (not shown).

[0035] When the clamping mechanism 23 transports the short tube to the second punching device 6, the second punching device 6 punches the short tube again. In this example, the second punching device 6 has the same structure and principle as the first punching device 4, which will not be described in detail here.

[0036] See Figure 6 , review Figure 1 , Figure 6Schematic diagram of the chamfering device structure in the embodiment. Preferably, in this example, a chamfering device 7 is also included. The chamfering device 7 is provided on the machine 1 and is located behind the second punching device 6 along the circumference of the turntable 22. The chamfering device 7 includes a third translation mechanism 71 and a chamfering plate 72. The third translation mechanism 71 is radially installed on the machine 1 along the turntable 22 and faces the rotating clamping device 2. The chamfering plate 72 is installed on the third translation mechanism 71. One side of the chamfering plate 721 is provided. The chamfering hole 721 is directly opposite to the movement path of the clamping port 23211. After the short tube is punched in the second punching device 6, the clamping mechanism 23 transports it to face the chamfering hole 721. Then, under the drive of the third translation mechanism 71, the chamfering plate 72 moves toward one end of the short tube. During the process, the chamfering hole 721 squeezes one end of the short tube to achieve chamfering of one end of the short tube. In this example, the third translation mechanism 71 is also composed of a cylinder, a slide rail, and a slider.

[0037] After the short tube is chamfered in the chamfering device 7, the clamping mechanism 23 transports it to the blank space between the chamfering device 7 and the feeding device 3 on the machine 1 for collection, and then the clamping mechanism 23 returns to the feeding mechanism 23 to continue clamping the short tube, and the above steps are circulated in sequence.

[0038] In summary, in this example, through the cooperation of the rotating clamping device, the loading device, the first punching device, the flipping device, the second punching device and the chamfering device, the fully automatic punching and end chamfering of different surfaces of the regular hexagonal short tube are achieved, which greatly improves the production continuity and thus improves the production efficiency.

Those skilled in the art will readily appreciate that various modifications and variations of the present invention are possible.
