Detailed Implementation

[0021] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0022] Please see Figures 1 to 3This utility model provides a technical solution: an automatic stamping equipment for flat strip steel plates, including an equipment body 1, an equipment base 11 and a stamping worktable 12 located on the equipment base 11, a stamping head 13 above the stamping worktable 12, a stamping die installed between the stamping worktable 12 and the stamping head 13, a feeding guide groove 14 on one side of the stamping worktable 12, the feeding guide groove 14 has a groove-shaped cross-section, which is used to guide the steel strip on the steel coil. After the steel strip passes through the stamping die, the stamping head 13 is controlled to descend to complete the stamping of the can lid.

[0023] In this technical solution, a material rack 2 is provided on one side of the equipment base 11. A row of rotating shafts 21 is provided on one side of the material rack 2. The rotating shafts 21 are used to suspend steel strip coils. In use, the roller sleeve in the middle of the steel strip coil is sleeved on the rotating shaft 21. Specifically, a crossbeam 23 is provided on the material rack 2. One end of the crossbeam 23 is fixedly connected to one side of the equipment base 11. A row of rotating shafts 21 is provided on one side of the crossbeam 23. A tensioning roller group 24 is provided on the material rack 2, located below each rotating shaft 21. The function of the tensioning roller group 24 is to press the steel strip coil suspended on each rotating shaft 21 to prevent the steel strip coil from becoming loose.

[0024] In this embodiment, a positioning plate 231 located on one side of the rotating shaft 21 is fixedly connected to the bottom of the crossbeam 23. The tensioning roller assembly 24 includes a slider 241, a support spring 242, and a pressure roller 243. One end of the slider 241 is slidably connected to one side of the positioning plate 231, and the pressure roller 243 is provided on its top. A pad 2311 is fixedly connected to the bottom of the positioning plate 231. A support spring 242 is provided between the pad 2311 and the slider 241. The support spring 242 applies an upward elastic thrust to the slider 241, thereby adjusting the pressure roller 243 to squeeze the bottom of the steel strip coil. In use, a foot pedal 2411 can be welded to the other end of the slider 241. The foot pedal 2411 is a foot pedal part, which is used to control the descent of the pressure roller 243 and facilitate the loading and unloading of the steel strip coil.

[0025] The feed rack 2 is equipped with a switching tube 22 that slides vertically and is located at the free end of the feeding guide groove 14. In practice, a guide shaft can be welded onto the feed rack 2, and a guide sleeve fitted onto the guide shaft can be welded onto the back of the switching tube 22. One side of the switching tube 22 has a through-hole 221, which is a rectangular hole structure used to insert sheet steel bars from the steel bar coil. During use, rollers located on the upper and lower sides of the through-hole 221 can be installed inside the switching tube 22 to reduce the resistance of the steel bars and to level them.

[0026] In this embodiment, baffles 141 located on one side of the switching tube 22 are welded to both the upper and lower sides of the feeding guide groove 14. The baffles 141 serve to block part of the insertion channel 221. A telescopic drive rod 4 is provided at the bottom of one of the baffles 141. The output shaft of the telescopic drive rod 4 is fixedly connected to one end of the switching tube 22. The telescopic drive rod 4 can be an electric push rod, which provides driving force for the switching tube 22 to slide up and down.

[0027] A roller conveyor 3 is installed on the feeding guide trough 14. The function of the roller conveyor 3 is to clamp the steel bar and transport the steel bar towards the stamping worktable 12 when it is running.

[0028] Specifically, the roller conveyor 3 includes a positioning plate 31, a slide block 32, a conveying roller 33, and a control motor 34. The positioning plate 31 is fixedly installed at the bottom of the feeding guide groove 14. There are two slide blocks 32 on both sides of the feeding guide groove 14. One side of the slide block 32 is elastically slidingly engaged with the positioning plate 31. In specific implementation, limit plates can be welded to both ends of the positioning plate 31. A compression spring is installed between the limit plate and the opposite slide block 32. At this time, the slide blocks 32 on both sides of the feeding guide groove 14 have a tendency to move in opposite directions. The control motor 34 is fixedly installed at the bottom of the slide block 32, and its output shaft is fixedly connected to the conveying roller 33. The control motor 34 provides driving force to the rotation of the conveying roller 33. The feeding guide groove 14 has notches 142 on both sides that are adapted to the conveying roller 33, thereby facilitating the conveying roller 33 to squeeze and transmit the steel strips passing through the feeding guide groove 14.

[0029] Furthermore, the conveying roller 33 has a grooved roller structure and the peripheral wall inside the groove is provided with circumferentially evenly distributed resistance-increasing strips 331. The cross-section of the resistance-increasing strips 331 can be a triangular structure, which can increase the friction between the conveying roller 33 and the side wall of the steel strip, and avoid slippage during transmission.

[0030] Working principle: A steel strip roll is placed on each rotating shaft 21. The steel strips from each roll are then inserted into the insertion channel 221 on the switching tube 22. The telescopic drive rod 4 is then controlled to align one insertion channel 221 with the guide groove on the feeding guide rail 14. The corresponding steel strip roll is then manually rotated to allow the steel strip to enter the feeding guide rail 14. The control motor 34 is then started, causing the conveyor roller 33 to rotate. When the steel strip contacts the conveyor roller 33, it is rolled, indicating that the current steel strip roll is in the feeding and docking completed state. After the current steel strip roll is used up, the switching tube 22 is slid to control the steel strips on other steel strip rolls to dock with the conveyor roller 33, following the same operation.

[0031] Furthermore, it should be understood that although this specification describes embodiments, not every embodiment contains only one independent technical solution. This narrative style is merely for clarity. Those skilled in the art should consider the specification as a whole, and the technical solutions in each embodiment can also be appropriately combined to form other embodiments that can be understood by those skilled in the art.
