Description

Technical Field

[0001] The utility model relates to the technical field of workpiece stamping, in particular to a fast and continuous stamping device for small workpieces. Background Art

[0002] Stamping is a production technology that uses the power of conventional or special stamping equipment to directly subject the sheet metal to deformation force in the mold and deform it, thereby obtaining product parts with a certain shape, size and performance. In the existing reduction motor production process, it is necessary to use automatic stamping equipment to stamp small workpieces.

[0003] During the stamping process of small metal workpieces for reduction motors, workers need to install the gear shaft into the stamping tube, and at the same time install the gear disc in the mounting disc, and use the stamping device to stamp and assemble the gear shaft and the gear disc. If there are operational errors or inaccurate transmission in this process, it will cause damage to the workpiece or reduce the precision, thereby affecting the product's qualification rate and stamping efficiency. In addition, manual operation may also cause operational errors due to fatigue and other reasons, which also increases the risk of product failure and the probability of causing accidents, and thus fails to achieve the best use effect of the stamping device.

At the same time, as the stamping seat rises, the gear disk can be inserted into the mounting disk. At this time, one of the second electromagnets under the transmission plate is powered off, and the second electromagnet after being powered off loses its magnetism and falls into the mounting disk.

[0027] When it is necessary to automatically stamp small workpieces, the fixed frame 7 can be driven to move by the setting of the transmission mechanism, so that the fixed frame 7 can be placed between the stamping seat 21 and the stamping plate 17, and as the stamping plate 17 moves downward, the gear shaft 11 can be adsorbed into the clamping hole 26 in the stamping tube 22 by the first electromagnet 27 after being energized. At the same time, as the stamping seat 21 rises, the gear plate 29 can be inserted into the mounting plate 30. At this time, one of the second electromagnets 28 under the transmission plate 8 is powered off, and the second electromagnet 28 after being powered off loses its magnetism and falls into the mounting plate 30, and then the gear shaft 11 is ... The setting of the dynamic mechanism pushes the fixed frame 7 to the end away from the stamping plate 17, so that the toothed disc 29 and the gear shaft 11 can be automatically stamped and assembled. When the small workpiece needs to be automatically stamped again, the transmission plate 8 can be driven to move to the right by the rotation of the second threaded rod 9, so that the gear shaft 11 can be installed inside the stamping tube 22. In this way, the device can be used to automatically stamp and assemble small metal workpieces, which relatively reduces the space for manual operation, thereby reducing the risk of product failure and the probability of causing accidents, and improving the stamping efficiency of small metal workpieces.

[0028] Reference Figure 1 The transmission mechanism includes fixed grooves 2 opened at both ends of the base 1, wherein a fixed rod 3 is fixedly connected to the inside of one of the fixed grooves 2, and a first threaded rod 4 is rotatably connected to the inside of the other fixed groove 2.

Both ends of the top of the bottom plate 5 are fixedly connected to L-shaped support plates 6, and a fixed frame 7 is fixedly connected between the two L-shaped support plates 6.

[0029] The rotation of the first threaded rod 4 can drive the movement of the base plate 5, and the setting of the fixed rod 3 can make the base plate 5 more stable during the movement and less prone to shaking, thereby shortening the distance between the gear shaft 11 and the gear disc 29 and the stamping plate 17, thereby facilitating the stamping assembly of the gear shaft 11 and the gear disc 29, and preventing the stamping plate 17 from accidentally hitting the fixed frame 7 during the falling process.

[0030] Reference Figure 3 The top of the base 1 is fixedly connected with an L-shaped fixing plate 13, the top of the L-shaped fixing plate 13 is fixedly installed with a hydraulic cylinder 14, the bottom end of the piston rod of the hydraulic cylinder 14 is fixedly connected with a lower pressing seat 16, and the bottom end of the lower pressing seat 16 is fixedly connected to the stamping plate 17.

[0031] The extension of the piston rod of the hydraulic cylinder 14 can drive the lower pressing seat 16 to descend, thereby adjusting the height of the punching plate 17 .

[0032] Reference Figure 2A mounting groove 25 is provided inside the base 1 and is located on the stamping seat 21. A cylinder 23 is fixedly installed inside the mounting groove 25. The piston rod of the cylinder 23 is fixedly connected to the stamping seat 21. A first servo motor 10 is fixedly installed outside the fixed frame 7. The output shaft of the first servo motor 10 extends to the inside of the fixed frame 7 and is fixedly connected to the second threaded rod 9.

[0033] By setting the cylinder 23, the height of the mounting plate 30 and the punching seat 21 can be raised, so that the toothed plate 29 can accurately fall into the mounting plate 30, and the rotation of the output shaft of the first servo motor 10 can drive the rotation of the second threaded rod 9.

[0034] Reference Figure 1 , buffer tubes 18 are fixedly connected to both ends of the bottom of the stamping plate 17, and buffer rods 19 are fixedly connected to both ends of the top of the stamping seat 21. The buffer rods 19 are slidably connected to the stamping plate 17 and the buffer tubes 18, and buffer springs 20 are sleeved on the outside of the buffer rods 19.

[0035] The buffer rod 19 , the buffer tube 18 and the buffer spring 20 are used in combination to reduce the downward impact of the buffer plate 17 , thereby avoiding damage to small metal workpieces caused by excessive downward pressure of the punching plate 17 .

[0036] Reference Figure 2 A second servo motor 24 is fixedly installed on the outer side of the base 1, and the output shaft of the second servo motor 24 extends to the inside of the fixing groove 2 and is fixedly connected to the first threaded rod 4. Two limit rods 15 are slidably connected to the inside of the L-shaped fixing plate 13, and the bottom ends of the limit rods 15 are fixedly connected to the lower pressure seat 16.

[0038] Working principle: When it is necessary to automatically stamp a small workpiece, the second servo motor 24 can be started, which can drive the rotation of the first threaded rod 4 and the movement of the base plate 5. Through the setting of the fixed rod 3, the base plate 5 can be made more stable during the movement and less prone to shaking, thereby shortening the distance between the gear shaft 11 and the gear disc 29 and the stamping plate 17, so that it is convenient to stamp and assemble the gear shaft 11 and the gear disc 29, and at the same time, it can prevent the stamping plate 17 from accidentally hitting the fixed frame 7 during the falling process. When the fixed frame 7 is between the stamping seat 21 and the stamping plate 17, the hydraulic cylinder 14 is controlled to start, and as the stamping plate 17 moves downward, the gear shaft 11 can be adsorbed in the clamping hole 26 in the stamping tube 22 through the energized first electromagnet 27. At the same time, the cylinder 23 is started to lift the position of the stamping seat 21. The toothed disc 29 can be inserted into the mounting disc 30. At this time, one of the second electromagnets 28 under the transmission plate 8 is powered off. After being powered off, the second electromagnet 28 loses its magnetism and falls into the mounting disc 30. Then, through the setting of the transmission mechanism, the fixed frame 7 is pushed to the end away from the stamping plate 17, and then the toothed disc 29 and the gear shaft 11 can be stamped and assembled. When it is necessary to automatically stamp the small workpiece again, the transmission plate 8 can be driven to move to the right by the rotation of the second threaded rod 9, so that the gear shaft 11 can be installed inside the stamping tube 22. In this way, the device can be used to realize automatic stamping and assembly of small metal workpieces, which relatively reduces the space for manual operation, thereby reducing the risk of product failure and the probability of causing accidents, and improving the stamping efficiency of small metal workpieces.
