Description

Technical Field

[0001] This invention relates to the field of stamping equipment technology, and more specifically to a housing stamping device. Background Technology

[0002] During the production process of the generator housing, a stamping device is used to stamp metal sheets into the generator housing. Through a guide structure, the upper mold is driven to descend, and then the metal sheet located on the lower mold is stamped. Furthermore, through the interchangeable upper and lower molds, the factory can stamp the metal sheet into housings of different shapes as needed.

[0003] Chinese invention patent CN116511351B discloses a metal stamping die and its usage method. The invention includes a housing, with a stamping cavity for stamping and a feeding cavity for placing metal sheets respectively opened at both ends of the top of the housing. The above-mentioned prior art enables the metal sheet to fully abut against the abutment table. On the other hand, if there is a metal sheet stuck on the inclined groove at the top of the limiting table, the metal sheet can also be pressed down by the clamping table, thereby enabling the metal sheet to be effectively positioned by the limiting table and the abutment table.

[0004] However, when stamping metal sheets into generator housings, the deformation of the metal sheets generates heat, leading to localized temperature increases. This not only causes the mold to overheat and affect its lifespan, but also causes the stamped metal sheets to soften due to overheating, resulting in springback during subsequent material handling. Therefore, existing technologies spray coolant to cool the metal sheets and molds. However, the thickness of the metal sheets varies in different parts of the generator housing, and different thicknesses require different stamping pressures. These different stamping pressures generate different amounts of heat during the stamping process. This results in a waste of coolant when the heat generated by the metal sheets is relatively low, even when spraying a large amount of coolant. Summary of the Invention

[0026] Compared with the prior art, the above technical scheme of the present application has the following beneficial technical effects: the metal plate for processing into a generator shell is placed on the lower die, when facing a thicker metal plate, the more the piston plate falls, the more air the piston plate compresses, so that the upper die at the bottom end of the piston plate is driven by air pressure to punch the metal plate, and when the piston plate falls, the cooling liquid in the inner cavity of the storage barrel is sucked into the inner cavity of the piston plate one through the inlet pipe, at this time, the L plate contacts the top end of the lower die, and the L plate is driven upward, thereby driving the blocking column in the inner cavity of the control pipe to block the circular pipe.

[0028] At the same time, the runner walks along the surface of the guide plate, the piston plate three is pushed by the movable plate in the inner cavity of the piston cylinder two, a certain amount of cooling liquid in the inner cavity of the piston cylinder two is sprayed from the spray head along the circular pipe and the control pipe to the surface of the metal plate, thereby realizing the determination of the strength or thickness of the metal plate according to the punching force, when the punching force is greater, more cooling liquid is sprayed, and vice versa, thereby avoiding the waste of cooling liquid.

[0029] When the upper die rises after the punching is completed, the rod two enters the curved slot along the straight slot, at this time, the guide plate is reciprocally shaken by the bending of the curved slot, and the lower die is vibrated by the guide plate, thereby shaking off the cooling liquid on the metal plate and the lower die, thereby realizing that when the upper die rises along the guide plate after the spraying is completed, the lower die vibrates, and the cooling liquid on the surface of the lower die is shaken off, thereby avoiding the large amount of residual cooling liquid, thereby affecting the recovery efficiency.

Inside the component, the movable end of the piston assembly moves with the traveling assembly; the guide plate 30 passes through the base frame 1 and is installed on the lower die mechanism, and the rotating wheel 27 is installed on the traveling assembly and moves elastically along the surface of the guide plate 30 through the traveling assembly; during stamping, the more distance the piston plate 13 descends in the inner cavity of the piston cylinder 11, the more coolant enters the inner cavity of the piston cylinder 11. After stamping, a fixed amount of coolant is delivered to the piston assembly. When the stamping assembly moves upward along the rod 5, the switch assembly releases the limit and opens. The rotating wheel 27 drives the piston assembly through the traveling assembly to spray a fixed amount of coolant onto the metal sheet through the switch assembly.

[0047] The elastic element 6 is installed at the bottom of the top plate 4 and its other end is connected to the upper mold 7. The piston assembly is installed inside the upper mold 7.

[0053] Through the setting of the switch assembly, the situation that more cooling liquid enters the piston cylinder 2 18 and directly overflows from the L plate 24 can be avoided.

[0054] The metering assembly includes a storage barrel 10, a driving device 2 12, a piston plate 2 14, an inlet pipe 16 and an outlet pipe 17.

[0056] The inlet pipe 16 is composed of a liquid inlet pipe and a one-way liquid inlet valve, and the outlet pipe 17 is composed of a liquid outlet pipe and a one-way liquid outlet valve.

[0060] In the second embodiment, as shown in the figure, the shell stamping device of the present application comprises a lower die mechanism, a switch unit, a rod two 15, a straight slot 31, a curved slot 32, and a reset slot 33. Figures 1-5 The lower die mechanism is installed in the base frame 1. The straight slot 31 is opened in the guide plate 30. The curved slot 32 is opened in the guide plate 30 and is connected to the upper side of the straight slot 31. The reset slot 33 is opened in the guide plate 30 and is connected to the end of the curved slot 32 close to the top plate 4. The bottom end of the reset slot 33 is connected to the straight slot 31. The rod two 15 is rotatably connected to the top plate 4 and is slidably connected to the reset slot 33. The switch unit is installed at the connection of the straight slot 31, the curved slot 32, and the reset slot 33. When the stamping starts, the top plate 4 descends and drives the rod two 15 to descend along the reset slot 33 and enters the straight slot 31 after passing the switch unit. When the stamping ends, the rod two 15 ascends along the straight slot 31 and ascends along the curved slot 32 due to the blockage of the switch unit, which drives the lower die mechanism at the bottom end of the guide plate 30 to vibrate and drain water. When it ascends to the top end, the guide plate 30 is pressed away by the elastic member of the walking unit, so that the rod two 15 enters the inner cavity of the reset slot 33.

[0061] The lower die mechanism comprises an elastic member two 8 and a lower die 9.

[0062] The elastic member two 8 is installed in the inner cavity of the base frame 1 and is connected to the lower die 9 at the other end. The lower die 9 is connected to the guide plate 30.

[0063] A cylindrical block is arranged on the lower die 9. A circular slot is opened in the upper die 7. The metal plate is placed on the lower die 9. The metal plate is stamped into a circular basin-shaped metal with the opening downward through the circular slot of the upper die 7.

[0064] The switch unit comprises an elastic member four 34 and a triangular block 35.

[0065] The switch unit comprises an elastic member four 34 and a triangular block 35.

[0066] The elastic member four 34 is installed in the guide plate 30 and connected to the triangular block 35 at the other end, the triangular block 35 is located at the joint of the straight slot 31, the curved slot 32 and the reset slot 33, the side of the triangular block 35 close to the straight slot 31 forms a straight surface with the straight slot 31 and the curved slot 32, and the other side faces the reset slot 33; when the rod two 15 contacts the triangular block 35 from the reset slot 33, the triangular block 35 is pressed downward along the inclined surface of the triangular block 35, and when the rod two 15 enters the curved slot 32 from the straight slot 31, the rod two 15 will rise linearly without entering the reset slot 33 because the straight slot 31, the curved slot 32 and the triangular block 35 are planar.

[0067] The elastic member one 6, the elastic member two 8, the elastic member three 25 and the elastic member four 34 are all composed of a telescopic rod and a spring two.

[0068] In the present application, the cooling liquid is added to the inner cavity of the storage barrel 10 through the liquid adding pipe at the top end of the storage barrel 10, then the metal plate is placed on the top end of the lower die 9, then the driving device one 2 is started to drive the threaded rod 3 to rotate, the top plate 4 engaged with the threaded rod 3 is driven to descend along the axis direction of the threaded rod 3 and the rod one 5, so that the upper die 7 first contacts the metal plate, and as the top plate 4 descends, the elastic member one 6 is contracted, and then the metal plate is limited by the close pressing of the upper die 7.

[0069] At this time, the runner 27 is located at the bottom end of the inclined surface of the guide plate 30 due to the elasticity of the elastic member three 25, and the piston plate three 28 is located at the side far away from the circular tube 19 at the joint of the discharge pipe 17 and the piston cylinder two 18.

[0070] Then the driving device two 12 is started to drive the piston plate one 13 to descend in the inner cavity of the piston cylinder one 11 to compress the air in the inner cavity of the piston cylinder one 11, when the metal plate is thicker or has higher strength, the driving device two 12 drives the piston plate one 13 to descend in the inner cavity of the piston cylinder one 11 for a longer distance, when the piston plate one 13 descends, the cooling liquid in the inner cavity of the storage barrel 10 is sucked into the inner cavity of the piston cylinder one 11 above the piston plate one 13 along the inlet pipe 16, and at the same time, the upper die 7 at the bottom end of the piston plate two 14 is driven to descend by the high pressure gas generated by the descending of the piston plate one 13, so that the metal plate is stamped by the upper die 7.

[0071] When the stamping is completed, the upper die 7 descends to the bottom end, at this time, the L plate 24 contacts the lower die 9, so as to drive the spray head 23 and the L plate 24 to ascend to block the circular tube 19 by the blocking column 22.

[0072] Next, drive device 212 is started to drive piston plate 13 to rise, no longer compressing the gas, and through the rise of piston plate 13, coolant is transported along discharge pipe 17 to the inner cavity of piston cylinder 218. Then drive device 2 is started to drive threaded rod 3 to rotate, which in turn drives top plate 4 to rise along rod 5. At this time, L plate 24 separates from lower mold 9, and through the elasticity of spring 20, control pipe 21 is driven to descend, so that blocking column 22 separates from round pipe 19.

[0073] When the top plate 4 rises, it drives the rotating wheel 27 to rise along the inclined surface of the guide plate 30, which in turn drives the rotating wheel 27 to move in the direction of the elastic element 25. This causes the piston plate 28 to move in the direction of the circular tube 19 through the movable plate 26, so that the coolant in the inner cavity of the piston cylinder 18 is sprayed out along the circular tube 19 and the spray head 23 to the surface of the metal plate, thereby cooling it.

[0074] When the top plate 4 rises, it drives the second rod 15 to enter the bending groove 32 along the straight groove 31. At this time, the bending of the bending groove 32 causes the guide plate 30 to shake, which in turn causes the lower mold 9 to vibrate. When the lower mold 9 vibrates, it shakes off the coolant from the surface of the metal sheet and the mold surface.

[0075] When the top plate 4 drives the second rod 15 to rise to the top, the elasticity of the third elastic element 25 drives the rotating wheel 27 to push the guide plate 30 away from the third elastic element 25, thereby causing the second rod 15 to enter the inner cavity of the reset groove 33. When stamping again, when the top plate 4 drives the second rod 15 to descend, it will descend along the reset groove 33, thereby avoiding vibration of the lower mold 9 during descent. When the second rod 15 contacts the inclined surface of the triangular block 35, it pushes the triangular block 35 towards the fourth elastic element 34, thereby causing the second rod 15 to return to the straight groove 31 for the next use.

[0076] The embodiments of the present invention have been described in detail above with reference to the accompanying drawings. However, the present invention is not limited thereto. Various changes can be made within the scope of knowledge possessed by those skilled in the art without departing from the spirit of the present invention.
