[0034] The present invention is further described in detail below in conjunction with the accompanying drawings and specific embodiments: Figure 1-Figure 10 A forging device for a lock box for a mechanical lock and a production process thereof, wherein the forging device comprises an upper die 1 and a lower die 2, wherein the forging device comprises a workbench 3, and a plurality of protrusions 4 are arranged on the surface of the workbench 3.

[0035] The protrusion 4 forms a complete square shape, and the lower mold 2 is placed in the protrusion 4. At the same time, a plurality of clamping components are arranged on the protrusion 4. The clamping components include a moving rod 5 and a clamping block 6. The moving rod 5 is slidably connected to the protrusion 4 on the opposite side, and the clamping block 6 is connected to the moving rod 5.

[0036] The moving rod 5 can be selected to use a screw rod, and the clamping block 6 slides on the other two groups of protrusions 4 without clamping components. When the clamping components clamp the lower mold 2, the clamping block 6 fits with the lower mold 2.

[0037] Generally, during the processing, the alloy plate workpiece is placed on the lower die 2. After the upper die 1 moves toward the lower die 2, the workpiece is formed in the lower die 2. Therefore, in general, the area of ​​the plate is larger than that of the lower die 2.

[0038] In order to facilitate the rapid imprinting of the brand logo on the formed box body, on some alloy metals, a common method is to set a universal imprinting part 11, then cover the surface of the box body with the imprinting part 11, and imprint it on the surface of the box body by pressing, thereby forming the brand logo.

[0039] At the same time, a through hole 31 is provided in the lower mold 2 at a suitable position, and the through hole 31 is used for the entry and exit of the engraved part 11. In order to facilitate the use of the engraved part 11, a control component is provided inside the workbench 3, and the control component includes a cylinder body 13, a control piston 14, a control tube 15 and a shunt tube. Specifically, the cylinder body 13 is sealed and movably connected with the control piston 14, and the control piston 14 is sealed and slidably connected to the cylinder body 13. The engraved part 11 is set on the top of the control block. After the control piston 14 in the cylinder body 13 moves, the engraved part 11 moves accordingly.

[0040] Furthermore, in order to facilitate the box body to be separated from the lower mold 2, a control spring 16 is arranged between the engraved part 11 and the control tube 15. Specifically, the engraved part 11 also includes a connecting head 17, and the connecting head 17 can be embedded in the top of the control tube 15. A moving tube 25 is arranged inside the control rod. The connecting head 17 is placed in coordination with the moving tube 25. A sealing ring 18 is arranged at the bottom of the moving tube 25, and the control spring 16 is arranged between the moving tube 25 and the sealing ring 18. When the control spring 16 is in a stationary state, the engraved part 11 is arranged slightly higher than the control tube 15.

[0041] When the control tube 15 moves, the engraving member 11 contacts the workpiece first, until the engraving member 11 overcomes the deformation of the control spring 16 and the engraving member 11 completely presses against the control tube 15 and engraves the workpiece.

[0042] After the upper mold 1 leaves the lower mold 2, under the action of the control spring 16, the engraving part 11 moves downward to separate from the mold. However, when some workpieces are too heavy and the control spring 16 cannot move, nitrogen can be flushed into the workpiece and the lower mold 2. After the nitrogen enters, a thin air cushion will be formed between the lower mold 2 and the workpiece. The air cushion can generate a certain pressure to separate the workpiece from the mold surface.

[0043] At the same time, in order to save costs, the volume of nitrogen filled is selected according to the weight of the workpiece. Therefore, a measuring component is set on the clamping block 6, wherein the measuring component includes a measuring rod 7 and a measuring tube 8, the measuring rod 7 slides in the measuring tube 8, a first piston 9 is set in the measuring tube 8, the first piston 9 seals and slides in the measuring tube 8, and a first spring 10 is set between the first piston 9 and the top of the measuring tube 8, and a plurality of one-way valves are set at the bottom of the measuring tube 8 for gas exchange.

[0044] Specifically, a first inlet check valve 19 and a first outlet check valve 20 are arranged at the bottom of the measuring tube 8, and the first inlet check valve 19 is connected to the inflation chamber through a hose. At the same time, the first outlet check valve 20 is connected to the control tube 15 through a hose. In practice, four groups of measuring components are arranged on the two clamping blocks 6, and the first inlet check valves 19 are connected to the inflation chamber 21 through hoses of various lengths to provide continuous air supply.

[0045] Furthermore, different gases can be placed in the gas filling chamber 21 as required, thus achieving the balance between protecting the demoulding of the workpiece and saving costs.

[0046] At the same time, in a specific operation, the sheet workpiece is placed on each measuring rod 7, and the measuring rod 7 moves according to the weight of the sheet workpiece. After the measuring rod 7 moves, a proper amount of gas can be filled into the control tube 15, and then enters the lower mold 2 through the control tube 15.

[0047] Specifically, the engraved part 11 includes a T-shaped jet channel, and the connecting head 17 is located below the engraved part 11. At the same time, the T-shaped jet channel passes through the engraved part 11 and the connecting head 17. The T-shaped jet channel protrudes from the engraved part 11 and the connecting head 17 to set a partial threaded tube 24. The threaded tube 24 is used to connect the moving tube 25, so as to realize the through connection between the T-shaped jet channel and the moving tube 25.

[0048] At the same time, a sealing plate 27 is connected to the bottom of the sealing ring 18, and the sealing plate 27 is connected to the bottom of the sealing ring 18 through a torsion spring. At the same time, the bottom of the moving tube 25 is located above the sealing plate 27. When the moving tube 25 overcomes the control spring 16 and the rotating plate overcomes the torsion spring and rotates, there is a gap between the sealing plate 27 and the sealing ring 18. At this time, after the first piston 9 moves, the gas in the control tube 15 can be sprayed from the T-shaped jet channel to form an air cushion between the lower mold 2 and the workpiece.

[0049] The T-shaped jet channel includes an inclined plate for gas ejection. Under the action of the inclined plate, the gas is ejected between the lower mold 2 and the workpiece to form an air cushion quickly, which is convenient for the protruding workpiece to be separated. The bottom of the T-shaped jet channel includes a first valve 26. When the first valve 26 is opened, the T-shaped jet channel can exchange gas. The control of the first valve 26 includes a third switch 40. When the third switch 40 is in a pressed state, the first valve 26 is closed.

[0050] The second inlet check valve 22 is arranged below the sealing ring 18 and is connected to the first outlet check valve 20 for collecting gas in each measuring tube 8. At the same time, a top block 28 is arranged on the side of the control piston 14 facing the sealing ring 18, and the top block 28 can make the sealing plate 27 contact with the sealing ring 18.

[0051] In order to start the movement of the control piston 14 and the first piston 9, a shunt pipe is set at the bottom of the cylinder body 13, and the shunt pipe includes a first channel 29 and a second channel 30. The first channel 29 passes through the control tube 15 through a hose seal, and the first channel 29 is connected to the control tube 15. The second channel 30 is set through the cylinder body 13. The second channel 30 on the outside of the rod body is connected to the drive chamber 32 through a hose. The drive source is released or recovered in the drive chamber 32.

[0052] At the same time, the driving source can be hydraulically driven or pneumatically controlled. At the same time, a through hole 31 is set in the second channel 30, and a control component is set on one side of the through hole 31. The control component includes a first electromagnet 34, a second electromagnet 35, a rotating shaft and a baffle 33. The rotating shaft and the baffle 33 are connected in the second channel 30. The first electromagnet 34 is located on one side of the through hole 31, and the second electromagnet 35 is located at the bottom of the second channel 30. The baffle 33 can be used in conjunction with any electromagnet. The outer side of the electromagnet is covered with a sealing material, and sealing can be achieved by contacting with the baffle 33.

[0053] Generally, the first electromagnet 34 is in an unactivated state, the second electromagnet is in an activated state, the baffle 33 is adsorbed on the second electromagnet 35, and the driving source is exchanged through the through hole 31. In order to start the first electromagnet 34, the first electromagnet 34 includes a first switch 38 and a second switch 39. The first switch 38 is arranged in a driving assembly of the forging device. The driving assembly includes a plurality of slide bars 36 and a slide sleeve 37 for moving the upper mold 1. The slide bar 36 slides in the slide sleeve 37, and the first switch 38 is located at the bottom of the slide sleeve 37.

[0054] When the upper mold 1 moves toward the lower mold 2 to press the first switch 38, the first switch 38 is in a pressed state. Conversely, when the upper mold 1 moves away from the lower mold 2, the first switch 38 is in an unpressed state. At the same time, the second switch 39 is set at the top of the control tube 15. When the engraving part 11 is against the control, the second switch 39 will be turned on. After the first switch 38 and the second switch 39 are turned on, the first electromagnet 34 is started, the baffle 33 is blocked by the through hole 31, and the driving source will drive the first piston 9 to move to release the gas. At the same time, an air cushion is formed between the lower mold 2 and the workpiece, and the engraving part 11 disengages and triggers the second switch 39. The top block 28 of the first piston 9 will fix the sealing plate 27.

[0055] At the same time, the third switch 40 is arranged on the adjacent side of the first switch 38, and is also controlled by the slide bar 36 to be in a pressed state. In the prior art, the first switch 38 is a normally closed type, and the pressed state is closed, the second switch 39 is a normally open type, and the pressed state is open, and the third switch 40 is a normally closed type, and the pressed state is closed.

[0056] Since the positions of the engraving holes 12 of different lower molds 2 are different, a moving component is set in the workbench 3, and the moving component includes a plurality of first track units and a second track unit. The first track unit includes two guide rails 42, and the guide rails 42 are matched and arranged on both sides below the workbench 3, and the guide rails 42 are horizontally arranged inside the workbench 3.

[0057] The second track unit includes a servo motor 46, a screw rod 44 and a guide rod 45. The screw rod 44 is rotatably connected between the sliders 43. At the same time, a slider 43 is set on the guide rail 42. The sliders 43 are connected by a plurality of guide rods 45. When any slider 43 is running, the two groups of sliders 43 will move synchronously.

[0058] Furthermore, the screw rod 44 is located between the guide rods 45, and the bottom of the cylinder body 13 is matched and connected to the screw rod 44 and the guide rod 45. Specifically, the bottom of the cylinder body 13 slides on the guide rail 42, and the screw rod 44 is matched and connected to the bottom of the cylinder body 13, so that when the screw rod 44 rotates, the cylinder body 13 can automatically slide on the guide rod 45.

[0059] In order to drive the screw rod 44 , generally, the screw rod 44 is connected to a servo motor 46 . In this embodiment, a notch is provided on the workbench 3 to match the servo motor 46 for the movement of the servo motor 46 .

[0060] Meanwhile, the hose in this embodiment is made of a flexible material and is provided with a margin when provided, so as to appropriately adapt to the movement of various components, and the driving source is pneumatically controlled.

[0061] Working principle: The lower die 2 and the upper die 1 are installed at the corresponding positions of the forging device, wherein the lower die 2 is arranged in the protrusion of the workbench 3 through the clamping assembly, and the measuring assembly on the clamping block 6 is used in cooperation, and the plate workpiece is placed on the measuring rod 7. According to the weight of the workpiece, the measuring rod 7 overcomes the movement of the measuring spring to realize that the gas of the corresponding weight enters the control assembly through the hose;

[0062] The lower die 2 moves, and the plate workpiece is processed into a box body workpiece. At this time, in order to facilitate the engraving of the brand logo, the engraved part 11 is moved to a position matching the engraved hole 12 of the lower die 2 through the driving assembly. After the upper die 1 and the lower die 2 are closed, the workpiece is processed. At this time, when the first switch 38 and the third switch 40 are both pressed, the drive chamber 32 is started, and the drive source enters the cylinder 13 through the through hole 31. The control piston 14 moves the control tube 15 in the cylinder 13. Since the first switch 38 is in a pressed state, the first valve 26 at the bottom of the T-shaped jet channel is closed;

[0063] After the upper die 1 leaves the lower die 2, the box body workpiece located in the lower die 2 needs to be separated. After the upper die 1 leaves the lower die 2, the box body workpiece can be ejected by using the control spring 16, or the drive chamber 32 can be started to eject the workpiece;

[0064] At the same time, if the workpiece is difficult to eject due to the low air pressure between the lower mold 2 and the workpiece, or the workpiece is damaged after forced ejection, the first switch 38 and the third switch 40 are in a non-pressed state, but the second switch 39 is in a pressed state, the first electromagnet 34 is started, and the baffle 33 rotates toward the first electromagnet 34. At the same time, when the third switch 40 is not pressed, the first valve 26 is opened, and after the drive chamber 32 is started, the gas is sprayed toward the lower mold 2 and the workpiece through the first valve 26 and the T-shaped jet channel, forming an air cushion while increasing the pressure, and smoothly driving the workpiece to separate from the lower mold 2.

[0065] The above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit the same. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art should understand that the technical solutions described in the aforementioned embodiments may still be modified, or some of the technical features may be replaced by equivalents. However, these modifications or replacements do not deviate the essence of the corresponding technical solutions from the spirit and scope of the technical solutions of the embodiments of the present invention.
