[0002] As a traditional type of lock, mechanical locks are still widely used in modern society. Mechanical locks have irreplaceable advantages compared to electronic locks. Among them, the operation method of mechanical locks is simple, and the unlocking time is short. Usually, only a key is needed to quickly unlock the lock. Secondly, mechanical locks do not require a power supply, so they can be used in various places without being restricted by power supply. Also, due to the simple structure of mechanical locks, their all-mechanical structure makes them highly reliable and able to adapt to various harsh environments. Importantly, mechanical locks do not have electronic components, so they are relatively cheap and widely used.
[0003] A mechanical lock mainly consists of a lock core body, a lock body, and a lock shell. When the lock shell is produced and processed, generally, a steel plate of a specific size is cut from a whole steel plate, and then workers will place the cut steel plate in a mold under a pressure forming device. Then, under the extrusion at the output end of the pressure forming device, the steel plate will be pressure formed into the bent shape of the mechanical lock shell. However, workers need to have a certain degree of proficiency during operation. Otherwise, the placement position may be inaccurate, and then workers need to place it again, which will affect the production efficiency of the pressure forming device. Summary of the Invention

Under the action of the pressure forming device, the lock shell workpiece is pressed into shape, completing the pressure forming operation of the lock shell.
[0015] The beneficial effects of the present invention are as follows: In the present invention, the lock shell workpiece is placed in the workpiece placement assembly, and the transfer mechanism is used to transfer the lock shell workpiece in the workpiece placement assembly to the forming die on the moving base directly below it. The workbench transfers the forming die with the lock shell workpiece placed on it from station one to station two, and under the action of the pressure forming device, the lock shell workpiece is pressed into shape, completing the pressure forming operation of the lock shell. During this process, only the lock shell workpieces need to be stacked in the workpiece placement assembly, and then under the control of the controller, the steps of moving and pressing the lock shell workpiece into shape can be achieved, reducing the steps of manual operation and otherwise there may be inaccurate manual placement situations, ensuring the production efficiency of the pressure forming device.
[0016] With the action of the transfer mechanism and the lifting component, the transfer mechanism can vertically rotate and move the lock shell workpiece when moving it, enabling it to move from the position directly above to the position directly below.

A sliding rod 21 is slidably connected to the spring plate 20. One end of the sliding rod 21 penetrates through the spring plate 20 and extends into the interior of the placement bin 19. A pressing plate 22 is connected to the end of the sliding plate located inside the placement bin 19. A spring 23 is connected between the pressing plate 22 and the spring plate 20, and the spring 23 is sleeved outside the sliding rod 21.
[0035] A feeding channel 24 for accommodating the lateral movement of the lock case is formed between the top of the bottom plate 16 and the bottom of the frame plate 17. The transfer mechanism 6 is arranged at one side position of the feeding channel 24. A first telescopic rod 25 is installed on the first support frame 14, and the first telescopic rod 25 is located at the other side position of the feeding channel 24.

[0036] To solve the problem of transferring the lock case workpiece from the placement bin 19 to the moving base 3; as Figure 7 - Figure 9 shown, the transfer mechanism 6 includes two lifting plates 27 connected to the second support frame 15 and symmetrically arranged, a lifting assembly longitudinally sliding between the two lifting plates 27, and a second telescopic rod 28 for driving the lifting assembly to move.

[0037] To solve the problem that when the sliding block 32 moves, the lock case workpiece can be vertically turned; as Figure 7 - Figure 9 shown, the lifting assembly includes a guide slot 33 opened on one side of the lifting plate 27 and a rotating shaft 34 rotatably connected to the two sliding blocks 32. The guide slot 33 is communicated with the lifting slot 30. The end of the rotating shaft 34 penetrates through the sliding block 32 and extends to the guide slot 33 and is connected with a gear 35. The gear 35 is located on the side of the guide slot 33 away from the lifting slot 30. A rack 36 is fixedly connected to the waist position on the side of the lifting plate 27 close to the gear 35. The rack 36 is movably meshed with the gear 35. A connecting rod 37 is fixedly connected to the side of the gear 35 away from the rotating shaft 34. One end of the connecting rod 37 is connected with a rotating rod 38. The end of the rotating rod 38 is connected with a guide wheel 39.

[0038] The guide slot 33 consists of a vertical slot 330 perpendicular to the first working station 201 and an open slot 331 opened at the waist position of the vertical slot 330. The open slot 331 connects the side wall of the vertical slot 330 with the outside of the lifting plate 27. The end of the rotating shaft 34 and the gear 35 are linearly moved in the guide slot 33 by the drive of the second telescopic rod 28. When the rack 36 is meshed with the gear 35, the rack 36 drives the gear 35 to rotate and drives the guide wheel 39 to vertically turn.
[0039] A connecting base 40 is fixedly connected to the rotating rod 38. A receiving plate 42 is fixedly connected to the connecting base 40 through a connecting rod 41. A plurality of vacuum suction cups 43 are provided on the receiving plate 42.

The buffer protrusion 45 is slidably connected in the buffer groove 44.
[0040] In order to solve the problem that the moving base 3 is unstable in position when placing the lock shell workpiece, a third support frame 48 is provided on one side of the workbench 2. A third telescopic rod 47 is provided on the third support frame 48. A stabilizing groove block 49 is connected to the side of the moving base 3 away from the central axis of the workbench 2. A trapezoidal stabilizing groove is formed on the stabilizing groove block 49. A trapezoidal block 50 that is movably matched with the stabilizing groove is provided at the movable end of the third telescopic rod 47.
[0041] It further includes a controller 46. The first telescopic rod 25, the second telescopic rod 28, the drive motor 10, the third telescopic rod 47, and the pressure forming device 7 are respectively electrically connected to the controller 46.
[0042] When this embodiment is in use, first, several steel workpieces of lock shells are vertically stacked in the placement bin 19. Then, the spring plate 20 is installed and clamped on the upper part of the placement bin 19. Then, under the cooperation and guidance of the spring 23 and the sliding rod 21, the pressing plate 22 on the spring plate 20 will extrude the stacked lock shell workpieces. As a result, the workpiece located below will be in the feeding channel 24. The controller 46 controls the operation of the first telescopic rod 25. The movable end of the first telescopic rod 25 drives the pushing plate 26 to move horizontally. The pushing plate 26 will then move and slide into the feeding channel 24, and then extrude the workpiece located in the feeding channel 24 and push it onto the transfer mechanism 6. Then, the movable end of the first telescopic rod 25 drives the pushing plate 26 to return to the initial position. At this time, under the action of the spring 23, a workpiece will be re-located in the feeding channel 24. By repeating this process, the workpieces in the placement bin 19 can be gradually pushed out to achieve the purpose of feeding one by one.
[0043] When the workpiece is pushed onto the receiving plate 42 of the connecting base 40, the vacuum suction cup 43 will adsorb it, so that its position will not shift during movement. Then, the controller 46 starts the operation of the second telescopic rod 28. The movable end of the second telescopic rod 28 drives the sliding block 32 to move. The sliding block 32 moves downward from the top of the vertical groove 330. When passing through the position of the rack 36, the gear 35 will be driven by the second telescopic rod 28 to mesh with the rack 36. And as the sliding block 32 continues to move, under the action of the rack 36, the gear 35 will drive the rotating shaft 34 to rotate. At this time, the guide wheel 39 is located at the position of the open groove 331. Therefore, when the guide wheel 39 rotates synchronously with the gear 35, the guide wheel 39 will not be restricted. Under the action of the rack 36, the gear 35 will rotate 180°. After the rotating shaft 34 rotates, the side of the receiving plate 42 for placing the workpiece faces the position of the workbench 2 at this time. Then, under the action of the second telescopic rod 28, the receiving plate 42 moves linearly to the position of the lower forming die 4. Then the vacuum suction cup 43 stops working. At this time, the workpiece will be placed into the forming die 4, thus completing the picking and placing of the workpiece. Finally, driven by the drive motor 10, the drive shaft 8 rotates, thereby driving the moving base 3 with the workpiece placed on it to rotate to the output end position of the pressure forming device 7, that is, to transfer from the position of station one 201 to the position of station two 202. Under the action of the pressure forming device 7, the lock shell workpiece is pressed into shape, completing the pressure forming operation of the lock shell.

The production process of the pressure forming device for mechanical locks according to claims 1-9, characterized in that: The production process includes the following steps: S1: When in use, a plurality of steel workpieces for lock shells are first stacked vertically in a placement bin (19), and then a spring plate (20) is mounted and clamped on the upper portion of the placement bin (19). Then, under the guidance of the spring (23) and the sliding rod (21), the pressing plate (22) on the spring plate (20) presses the stacked lock shell workpieces, thereby causing the workpiece located below to be located in the loading channel (24); S2: The controller (46) controls the telescopic rod (25) to operate, and the movable end of the telescopic rod (25) drives the push plate (26) to move horizontally. The push plate (26) then moves and slides into the feeding channel (24), and then squeezes the workpiece in the feeding channel (24) out and pushes it onto the transfer mechanism (6). Then, the movable end of the telescopic rod (25) drives the push plate (26) to return to the initial position. At this time, under the action of the spring (23), the workpiece is relocated in the feeding channel (24). This cycle is repeated, and the workpieces in the placement bin (19) can be gradually pushed out to achieve the purpose of loading one by one. S3: When the workpiece is pushed onto the receiving plate (42) of the connecting base (40), the vacuum suction cup (43) will absorb it so that it will not be offset in position when moving. Then the controller (46) starts the operation of the telescopic rod 2 (28). The movable end of the telescopic rod 2 (28) drives the sliding block (32) to move. The sliding block (32) moves downward from the top of the vertical groove (330). When passing the position where the rack (36) is located, the gear (35) is driven by the telescopic rod 2 (28) to mesh with the rack (36). The gear (35) continues to move with the sliding block (32). Under the action of the rack (36), the gear (35) drives the rotating shaft (34) to rotate. At this time, the guide wheel (39) is located at the position of the open groove (331). Therefore, when the guide wheel (39) rotates synchronously with the gear (35), the guide wheel (39) will not be restricted. S4: Under the action of the rack (36), the gear (35) will rotate (180) degrees. After the rotating shaft (34) rotates, the side of the receiving plate (42) on which the workpiece is placed faces the position of the workbench (2). Then, under the action of the second telescopic rod (28), the receiving plate (42) moves linearly to the position of the molding die (4) below. Then, the vacuum suction cup (43) stops working. At this time, the workpiece is placed in the molding die (4), thereby completing the picking up and placement of the workpiece. S5: Finally, driven by the driving motor (10), the driving shaft (8) rotates, thereby driving the movable base (3) on which the workpiece is placed to rotate to the output end position of the pressure forming device (7), that is, transferring from the position of station one (201) to the position of station two (202). Under the action of the pressure forming device (7), the lock shell workpiece is pressed and formed, thereby completing the pressure forming operation of the lock shell.
