Description

Technical Field

[0001] The utility model relates to an aluminum material stamping processing device, belonging to the field of aluminum material processing. Background Technique

[0002] The square aluminum tube is a kind of aluminum material. The surface of the square aluminum tube usually needs to be punched. When punching the square aluminum tube, first insert the square aluminum tube into a positioning sleeve with a rectangular cross-section. A mandrel is inserted into the positioning sleeve, and the mandrel supports the inner wall of the square aluminum tube. Thus, during the punching operation, it can prevent the square aluminum tube from deforming due to extrusion. One end of the mandrel in the positioning sleeve is processed with a cavity for accommodating the slug. For a long square aluminum tube that needs to be punched with multiple holes, when punching is completed at one place of the square aluminum tube, restricted by the mandrel and the square aluminum tube together, the punched slug cannot be discharged from the cavity of the mandrel in time, and the slug in the cavity of the mandrel needs to be cleaned after a certain number of punching times. This method affects the processing efficiency of aluminum material stamping. Content of the Utility Model

[0003] Aiming at the deficiencies of the prior art, the purpose of the utility model is to provide an aluminum material stamping processing device to solve the problems put forward in the above background technique. The utility model provides a direct discharge channel for discharging the punched slug, making the aluminum material stamping continuous.

[0004] In order to achieve the above purpose, the utility model is realized by the following technical solutions: an aluminum material stamping processing device, including a positioning sleeve for restricting the position of the square aluminum tube. The cross-section of the positioning sleeve is rectangular. A through hole for the punch to pass through is opened in the middle position of the upper surface of the positioning sleeve. A mandrel for inserting into the square aluminum tube is inserted into the positioning sleeve. There is a gap equal to the wall thickness of the square aluminum tube between the mandrel and the positioning sleeve. A discharge port is opened at the position of the upper surface of the mandrel in the positioning sleeve. The discharge port is aligned with the through hole. A discharge groove is arranged in the mandrel along the length direction of the mandrel. The discharge port is communicated with the discharge groove. The bottom of the discharge groove is an inclined surface. A driving part for driving the slug to move is slidably installed at the lower part in the discharge groove.

[0005] Further, the driving member includes an inclined plate which is slidably installed at the lower part inside the discharge chute. The inclination angle of the inclined plate is the same as that of the inclined surface. One end of the inclined plate away from the positioning sleeve is fixedly connected with an ear plate. A magnet block is installed at the upper part of the surface of the ear plate facing the positioning sleeve. A positioning plate is provided on the side of the magnet block away from the ear plate. The upper end of the positioning plate is fixedly connected with the core rod. An electromagnet which repels the magnet block is installed on the surface of the positioning plate facing the ear plate. A perforation is formed at the lower part of one side surface of the positioning plate. A shaft rod is inserted into the perforation. One end of the shaft rod is fixedly connected with the ear plate. A limiting disc is fixedly connected to the end of the shaft rod away from the ear plate. A spring is arranged between the limiting disc and the positioning plate, and the spring is sleeved on the shaft rod.

[0006] Further, an external thread is processed at the end of the shaft rod away from the limiting disc. The end of the shaft rod processed with the external thread is threadedly connected with a threaded sleeve, and the threaded sleeve is fixedly connected with the ear plate.

[0007] Further, a support frame is fixedly connected to the lower surface of the positioning plate. The cross-section of the support frame is T-shaped, and two small holes are symmetrically formed in the horizontal part of the support frame.

[0008] Further, a baffle is fixedly connected to the end of the inclined plate away from the ear plate, and the end of the baffle away from the inclined plate is inclined upward.

[0009] Further, a U-shaped plate for supporting the square aluminum tube is provided on the side of the positioning sleeve away from the ear plate. Two connecting rods are fixedly connected to the lower part of the surface of the U-shaped plate facing the positioning sleeve, and the other ends of the connecting rods are fixedly connected with the positioning sleeve. First rectangular openings are formed in both vertical parts of the U-shaped plate, and a second rectangular opening is formed in the horizontal part of the U-shaped plate.

[0010] Further, connecting seats are fixedly connected to the lower edges of the two parallel side surfaces of the positioning sleeve, and two fixing holes are formed in the upper surface of the connecting seats.

[0011] Advantages of the utility model:

[0012] 1. Place the square aluminum tube in the U-shaped plate. At this time, the U-shaped plate supports the square aluminum tube. Under the guidance of the U-shaped plate, it is convenient to smoothly insert the square aluminum tube into the gap between the core rod and the positioning sleeve, improving the efficiency of inserting the square aluminum tube into the gap between the core rod and the positioning sleeve.

[0013] 2. After the square aluminum tube is inserted into the gap between the core rod and the positioning sleeve, the punch presses the square aluminum tube through the through port under the drive of the driving device, so that the material head punched from the square aluminum tube is discharged from the discharge port and the discharge chute. There is no need to manually clean the material head actively after stamping a certain number of times, providing a direct discharge channel for discharging the punched material head, making the aluminum material stamping continuous.

[0014] 3. Control the electromagnet to switch between energized and de-energized states. When the electromagnet is energized, it generates magnetism and repels the magnet block. At this time, under the action of the repulsive force, the ear plate moves towards the positioning plate. At this time, the inclined plate slides along the inclined surface at the bottom of the discharge chute. During the movement of the ear plate, the shaft rod is driven to move, and the shaft rod drives the limit disc to squeeze the spring, causing the spring to undergo elastic deformation. When the electromagnet is de-energized, under the action of the spring's resilience force, the inclined plate slides in the reverse direction. By repeating the above operations, the inclined plate slides back and forth in the discharge chute, and the reciprocating inclined plate accelerates the discharge of the stock heads falling into the discharge chute.

[0015] 4. Install an upwardly inclined baffle at one end of the inclined plate away from the ear plate. Thus, under the blocking of the baffle, it is prevented that the stock heads falling into the discharge chute are discharged from the feeding side of the positioning sleeve during the movement of the inclined plate.

[0025] Please refer to Figure 1 , Figure 2 and Figure 6 , the present utility model provides a technical solution: an aluminum material stamping and processing device, including a positioning sleeve 1 for restricting the position of a square aluminum tube. The cross-section of the positioning sleeve 1 is rectangular. A through hole 2 for the punch to pass through is provided in the middle of the upper surface of the positioning sleeve 1. Fixed connection seats 5 are connected to the lower edges of two parallel sides of the positioning sleeve 1. Two fixing holes are provided on the upper surface of the connection seat 5. The connection seat 5 is installed on the stamping table of the stamping machine by bolts to complete the restriction of the position of the positioning sleeve 1.

[0026] Refer to Figure 1 , Figure 2 and Figure 6 , on the side of the positioning sleeve 1 away from the ear plate 11, there is a U-shaped plate 4 for supporting the square aluminum tube. Two connecting rods 3 are fixedly connected to the lower part of the side of the U-shaped plate 4 facing the positioning sleeve 1. The other ends of the connecting rods 3 are fixedly connected to the positioning sleeve 1. The connecting rods 3 play a role in connecting the positioning sleeve 1 and the U-shaped plate 4. First rectangular openings 20 are provided in both vertical parts of the U-shaped plate 4, and a second rectangular opening 21 is provided in the horizontal part of the U-shaped plate 4 to reduce the material consumption of the U-shaped plate 4. The square aluminum tube is placed in the U-shaped plate 4. At this time, the U-shaped plate 4 realizes the support of the square aluminum tube. Under the guidance of the U-shaped plate 4, it is convenient to smoothly insert the square aluminum tube into the gap between the core rod 6 and the positioning sleeve 1, improving the efficiency of inserting the square aluminum tube into the gap between the core rod 6 and the positioning sleeve 1.

[0027] Refer to Figures 1 - 4 , a core rod 6 for inserting into the square aluminum tube is inserted into the positioning sleeve 1. There is a gap between the core rod 6 and the positioning sleeve 1 that is the same as the wall thickness of the square aluminum tube. A discharge port 16 is provided at the position of the upper surface of the core rod 6 inside the positioning sleeve 1. The discharge port 16 is aligned with the through hole 2. A discharge groove 17 arranged along the length direction of the core rod 6 is provided inside the core rod 6. The discharge port 16 is communicated with the discharge groove 17. The bottom of the discharge groove 17 is an inclined surface. After the square aluminum tube is inserted into the gap between the core rod 6 and the positioning sleeve 1, the punch punches the square aluminum tube through the through hole 2 under the drive of the driving device, so that the cut-off material head on the square aluminum tube is discharged from the discharge port 16 and the discharge groove 17, without the need to manually clean the material head actively after stamping a certain number of times, providing a direct discharge channel for discharging the cut-off material head, making the aluminum material stamping continuous.

[0028] Refer to Figures 1 - 5, a sloping plate 12 is slidably installed at the lower position inside the discharging chute 17. The inclination angle of the sloping plate 12 is the same as that of the inclined surface. One end of the sloping plate 12 far from the positioning sleeve 1 is fixedly connected with an ear plate 11. A magnet block 13 is installed at the upper position on the side of the ear plate 11 facing the positioning sleeve 1. A positioning plate 9 is provided on the side of the magnet block 13 away from the ear plate 11. The upper end of the positioning plate 9 is fixedly connected with the core rod 6. An electromagnet 18 that repels the magnet block 13 is installed on the side of the positioning plate 9 facing the ear plate 11. A perforation is opened at the lower position on one side surface of the positioning plate 9. A shaft rod 10 is inserted into the perforation. An external thread is processed at one end of the shaft rod 10 far from the limiting disc 7. A threaded sleeve 19 is threadedly connected to the end of the shaft rod 10 processed with the external thread, so that the threaded sleeve 19 is fixedly connected with the ear plate 11, completing the connection and fixation of one end of the shaft rod 10 with the ear plate 11. A limiting disc 7 is fixedly connected to the end of the shaft rod 10 far from the ear plate 11. A spring 8 is provided between the limiting disc 7 and the positioning plate 9. The spring 8 is sleeved on the shaft rod 10. A support frame 14 is fixedly connected to the lower surface of the positioning plate 9. The cross-section of the support frame 14 is T-shaped. Two small holes are symmetrically opened on the horizontal part of the support frame 14. The support frame 14 is installed at the required position of the stamping machine by using bolts, completing the limitation of the position of the core rod 6. The PLC controller is used to control the electromagnet 18 to switch between energization and de-energization. When the electromagnet 18 is energized, it generates magnetism and repels the magnet block 13. At this time, under the action of the repulsive force, the ear plate 11 moves towards the positioning plate 9. At this time, the sloping plate 12 slides along the inclined surface at the bottom of the discharging chute 17. The ear plate 11 drives the shaft rod 10 to move during the movement process. The shaft rod 10 drives the limiting disc 7 to squeeze the spring 8, causing the spring 8 to generate elastic deformation. When the electromagnet 18 is de-energized, under the action of the restoring force of the spring 8, the sloping plate 12 slides in the reverse direction. By repeating the above operations, the sloping plate 12 slides back and forth in the discharging chute 17, and the sloping plate 12 that slides back and forth accelerates the discharge of the stock heads falling into the discharging chute 17.

[0029] Refer to Figure 2 and Figure 5 , a baffle 15 is fixedly connected to one end of the sloping plate 12 far from the ear plate 11. One end of the baffle 15 far from the sloping plate 12 is inclined upward. By installing the upward-inclined baffle 15 at one end of the sloping plate 12 far from the ear plate 11, further under the block of the baffle 15, it is prevented that the stock heads falling into the discharging chute 17 are discharged from the feeding side of the positioning sleeve 1 during the movement of the sloping plate 12.
