Description

Technical Field

[0001] This utility model relates to the field of lock beam bending technology, specifically a multi-station bending and forming machine for padlock lock beams. Background Technology

[0002] The earliest copper spring locks in China appeared in the Han Dynasty, while Western all-metal padlocks were invented between 870 and 900 AD. By the Roman period, barbed spring padlocks had appeared, which were locked by a bolt and a spring and could only be opened by pressing the spring with a key, demonstrating the combination of early mechanical structure and safety design.

[0003] Before assembling a padlock, the lock beam needs to be bent. Currently, common lock beam production equipment involves manually feeding one end of an iron bar between a fixed block and a rotating block. The rotating block then bends the iron bar into a lock beam shape by rotating around the fixed block. This type of lock beam bending operation requires long hours of manual work, resulting in high labor intensity and fatigue for the workers, thus reducing work efficiency. Therefore, a multi-station padlock lock beam bending and forming machine is proposed. Utility Model Content

[0004] The purpose of this invention is to provide a multi-station bending and forming machine for padlock beams to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: It includes a workbench, a support frame connected to the top of the workbench, a conveyor box connected to the top of the support frame, a motor connected to one side of the conveyor box, the output end of the motor extending into the conveyor box and connected to a feeding roller, four feeding grooves on the surface of the feeding roller, a storage box connected to the top of the conveyor box, a feed inlet on the top of the storage box, hollow plates connected to both sides of the conveyor box, and discharge outlets corresponding to the hollow plates on both sides of the conveyor box, bending mechanisms connected to both sides of the top of the workbench, receiving grooves on both sides of the top of the workbench, bending grooves at the bottom of the receiving grooves, limiting grooves on both sides of the bending grooves, two rigid springs connected to the bottom of the bending grooves, top plates connected to the tops of the rigid springs and slidably disposed within the limiting grooves, and through holes on both sides of the receiving grooves at the top of the workbench.

[0015] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0016] Please see Figures 1-6This utility model provides a technical solution, including a workbench 1, a support frame 2 connected to the top of the workbench 1, a conveyor box 3 connected to the top of the support frame 2, a motor 4 connected to one side of the conveyor box 3, the output end of the motor 4 extending into the conveyor box 3 and connected to a feeding roller 5, the surface of the feeding roller 5 having four feeding grooves 6, a storage box 7 connected to the top of the conveyor box 3, a feeding port 8 at the top of the storage box 7, and hollow plates 9 connected to both sides of the conveyor box 3, with corresponding hollow plates 9 on both sides of the conveyor box 3. Each workbench 1 has a discharge port 10. Bending mechanisms 11 are connected to both sides of the top of the workbench 1. Material receiving grooves 12 are provided on both sides of the top of the workbench 1. Bending grooves 13 are provided at the bottom of the material receiving grooves 12. Restricting grooves 14 are provided on both sides of the inside of the bending grooves 13. Two high-strength springs 15 are connected to the bottom of the inside of the bending grooves 13. Top plates 16 are connected to the top of the high-strength springs 15 and are slidably disposed inside the restricting grooves 14. Through holes 17 are provided on both sides of the material receiving grooves 12 at the top of the workbench 1.

[0017] The bending mechanism 11 includes a gantry frame 111 connected to the top of the workbench 1. A hydraulic cylinder 112 is connected to the top of the gantry frame 111. The output end of the hydraulic cylinder 112 passes through the top of the gantry frame 111 and is connected to a slide plate 113. A connecting column 114 is connected to the bottom of the slide plate 113. A mounting base 115 is connected to the bottom of the connecting column 114. A punching head 116 is connected inside the mounting base 115. Guide grooves 117 are provided on both sides of the gantry frame 111 corresponding to the slide plate 113. The top of the gantry frame 111 has guide grooves 117 on both sides. Guide rods 118 are connected to both the gantry frame 111 and the worktable 1, with one end of the guide rod 118 passing through the gantry frame 111 and the worktable 1, and connected inside the through hole 17. A stabilizing spring 119 is connected between the top of the worktable 1 and the bottom of the gantry frame 111, and the stabilizing spring 119 is sleeved on the surface of the guide rod 118. Its function is to prevent the slide from shifting or shaking during the movement, thereby ensuring that the stamping head can accurately align with the part to be bent during the bending process, which greatly improves the accuracy of the bending process and ensures the consistency of product size and shape.

[0018] Each of the two hollow plates 9 has a baffle 18 connected to its bottom side, and two L-shaped baffles 24 connected to its top. A receiving trough 12 is positioned between the baffles 18 and L-shaped baffles 24. This arrangement creates a relatively enclosed and clearly defined receiving area. When material is conveyed or falls from the hollow plates, the baffles and L-shaped baffles act as positioning and guiding elements, ensuring the material falls accurately into the receiving trough and preventing it from scattering outside, thus improving the accuracy and efficiency of receiving.

[0019] Two placement holes 19 are opened on one side of each of the two baffles 18. An H-shaped support frame 20 is connected to the bottom of the hollow plate 9 on the other side of the baffle 18. A nozzle 21 is connected inside the placement hole 19. An air pipe 211 is connected to the bottom of the H-shaped support frame 20, and the nozzle 21 is connected to the air pipe 211. A connecting pipe 212 is connected to the middle of each of the two air pipes 211. Its function is to connect the nozzle to an external high-pressure air source and spray the pushed-out lock beam to one side.

[0020] I-shaped reinforcing rods 22 are connected between the support frames 2, and four support legs 23 are connected to the bottom of the worktable 1. The four support legs 23 are arranged in a rectangular shape. Their function is to connect the I-shaped reinforcing rods between the support frames. The I-shaped structure itself has good mechanical properties. Its special cross-sectional shape (combination of upper and lower flanges and web) can provide high bending and torsional strength. The four support legs are arranged in a rectangular shape. This layout conforms to the mechanical principle and can provide uniform and stable support force for the worktable.

[0021] Both sides of the workbench 1 are connected to guide plates 25 on one side of the receiving trough 12. The purpose of the guide plates is to allow the material after bending to slide smoothly down its inclined surface, thus avoiding the accumulation of material near the receiving trough.

[0022] The bending groove 13 is located at the bottom right of the receiving groove 12, and the punching head 116 is horizontally positioned with the bending groove 13. Its function is to reduce the scrap rate caused by positional deviation and ensure the consistency of product quality.

[0023] Working principle: The blank of the locking beam is first placed in the storage box 7 and enters the conveying box 3 through the feed port 8. The motor 4 drives the conveying roller 5 to rotate. The four conveying grooves 6 on the surface of the conveying roller 5 continuously convey the blank from the conveying box 3 to the discharge port 10 of the hollow plate 9 on both sides of the conveying box 3. The blank is guided by the conveying grooves 6 to the discharge port 10. At the hollow plate 9, it is distributed to the receiving grooves 12 on both sides. The hydraulic cylinder 112 pushes the slide plate 113 to move downward. The connecting column 114 at the bottom of the slide plate 113 drives the mounting base 115 and the punch head 116 to move downward. The guide rod 118 and the guide groove 117 ensure the vertical movement accuracy of the punch head 116. The stabilizing spring 119 is used to balance the weight of the slide plate 113 and absorb the impact force to a certain extent. The punch head 116 enters the bending groove 13 to bend the blank. The rigid spring 15 provides sufficient support force, and the top plate 16 slides within the limiting groove 14 to ensure the accuracy and stability of bending. The hydraulic cylinder 112 retracts, and the slide plate 113, connecting column 114, mounting base 115 and stamping head 116 move upward to return to the initial position. At the same time, the rigid spring 15 releases kinetic energy to push the top plate 16, which pushes out the locking beam. The nozzle 21 is connected to an external powerful air source by the air pipe 211 and connecting pipe 212, which blows the pushed-out locking beam to one side, and finally it is smoothly discharged by the guide plate 25.
