[0020] In order to make the purpose, technical solution and advantages of the present invention more clearly understood, the present invention is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not used to limit the present invention.

[0021] refer to Figure 1-Figure 5A modular unloading mechanism for punching a short pipe with an undercut, as shown, includes a linear module 1, a slide table 2 and a carrier 6. A first cylinder 3 and a mounting seat 4 are arranged on the slide table 2. The piston rod of the first cylinder 3 is fixedly connected to the mounting seat 4. A first adjustment groove 401 is opened at the lower end of the mounting seat 4. A plurality of undercut collets 5 are fixedly connected at the first adjustment groove 401 through a screw. The undercut collets 5 are used for short pipes. The undercut collet 5 includes a cylinder body 501, a slide rod 502 and a stop block 503 slidably connected to the cylinder body 501. The cylinder body 501 can guide the sliding of the slide rod 502 and the stop block 503 to prevent the slide rod 502 and the stop block 503 from shifting during the sliding process. One end of the slide rod 502 extends out of the cylinder body 501 and is provided with a rotating shaft 504. The other end of the slide rod 502 extends into the cylinder body 501 and is fixedly connected to the stop block 503. A first spring 505 is sleeved on the slide rod 502. A second cylinder 7 is arranged on the carrier 6. A support plate 701 is fixedly connected to the piston rod of the second cylinder 7. A second adjustment groove 601 is opened on the side wall of the carrier 6. A plurality of placing seats 8 are fixedly connected at the second adjustment groove 601 through a screw. Elastic insertion plates 9 are arranged above the support plate 701 on both sides of each placing seat 8. A positioning ring 801 is fixedly connected to the placing seat 8. The positioning ring 801 is used for positioning and placing short pipes.

[0022] The slide table 2 is fixedly connected to the moving table of the linear module 1. The mounting seat 4 is slidably connected to the slide table 2. The slide table 2 can guide the sliding of the mounting seat 4 to prevent the mounting seat 4 from shifting during the sliding process. A columnar protrusion is arranged at the upper end of the cylinder body 501. The screw passes through the first adjustment groove 401 and is threadedly connected to the columnar protrusion.

[0023] An inclined surface is arranged at the lower end of the stop block 503. The stop block 503 is used for blocking the undercut part of the short pipe after it is inserted, so as to complete the material taking. The rotating shaft 504 is rotatably connected to the slide rod 502. The first spring 505 is located between the stop block 503 and the cylinder body 501. The first spring 505 is used for resetting the stop block 503.

[0024] A guide post 10 is fixedly connected to the carrier 6 beside the second cylinder 7. The support plate 701 is slidably connected to the guide post 10. The guide post 10 can guide the sliding of the support plate 701 to prevent the support plate 701 from shifting during the sliding process. The placing seat 8 is in a U shape. The support plate 701 is located in the notch of the placing seat 8.

[0025] The elastic plug plate 9 includes an L-shaped plug plate 901 and a second spring 902. The L-shaped plug plate 901 is slidably connected to the placement seat 8. The placement seat 8 can guide the sliding of the L-shaped plug plate 901 to prevent the L-shaped plug plate 901 from deflecting during the sliding process. The second spring 902 is arranged between the L-shaped plug plate 901 and the placement seat 8. The upper end of the L-shaped plug plate 901 is provided with an inclined surface. The end of the sliding rod 502 extending out of the cylinder 501 is provided with a makeshift groove. The L-shaped plug plate 901 is correspondingly arranged with the makeshift groove. When the short tube is unloaded to the positioning ring 801, the makeshift groove makes way for the L-shaped plug plate 901.

[0026] A calibration hole 5011 is opened on the cylinder 501, and a laser emitter 11 is fixedly connected to the side of the placement seat 8. The laser emitter 11 is arranged corresponding to the calibration hole 5011. When the laser emitter 11 is arranged to adjust the position of the placement seat 8, the relative position of the placement seat 8 and its corresponding inverted collet 5 can be quickly calibrated.

[0027] The working principle of the present invention is: before use, the present invention firstly performs the number of short tubes to be processed synchronously by the unloading punching die according to the needs, selects the appropriate position of the corresponding number of inverted collet chucks 5 on the mounting seat 4 and fixes them at the first adjustment groove 401 by means of screws, and the short tubes are in the middle of the inverted collet chucks 5 during unloading, and then selects the same number of placement seats 8 as the inverted collet chucks 5, turns on the laser transmitter 11 switch, slides the placement seat 8 along the second adjustment groove 601 to the appropriate position, aligns the laser spot with the calibration hole 5011, and then fixes the position of the placement seat 8 by means of screws.

[0028] When the present invention is in use, the linear module 1 and the carrier 6 are both fixedly connected to the external frame. When the short tube completes the lateral punching, the piston rod of the first cylinder 3 extends out, and the mounting seat 4 descends. During the descending process, the inverted portion of the upper end of the short tube first pushes the two blocks 503 to the outside of the cylinder 501 until the inverted portion completely passes through the block 503. At this time, under the action of the first spring 505, the block 503 is reset to block the lower part of the inverted portion. Subsequently, when the piston rod of the first cylinder 3 is retracted, the inverted collet 5 lifts the short tube on the punching die, and then the linear module 1 drives the slide 2 and the mounting seat 4 to slide to the unloading station, and then the piston rod of the first cylinder 3 is retracted. The L-shaped insert plate 901 will be lifted up and contacted with the rotating shaft 504 on the sliding rods 502 on both sides of each cylinder 501 during the rising process, and the two sliding rods 502 will be pushed toward the outside of the cylinder 501 through the inclined surface on the L-shaped insert plate 901, so that the short tube is separated from the stopper 503, so that the short tube completely falls into the positioning ring 801, and then the piston rod of the first cylinder 3 is retracted to complete the unloading action. The present invention is suitable for the automatic unloading of different punching and cutting dies, and the unloading is regular. It adopts a modular structure, and the inverted collet chuck 5 and the placement seat 8 are easy to disassemble and assemble.
