Description

Technical Field

[0001] This application relates to the field of stamping apparatus technology, and in particular to a stamping apparatus for processing aluminum alloy forgings. Background Technology

[0002] Aluminum alloy forgings are widely used in machinery manufacturing, automotive parts and other fields. Stamping is one of the key processes in the processing of aluminum alloy forgings. During the stamping process, due to the shearing of the material along the edge of the die, burrs, flash and local protrusions are inevitably generated at the parting surface and contour edge of the forging. If these residual defects are not removed in time, they will affect the subsequent assembly accuracy and may also scratch the operators during handling and use. Therefore, after the forging is stamped, it must go through a grinding and deburring process before it can enter the next production stage.

[0003] Currently, after aluminum alloy forgings are formed by stamping equipment, burrs and flash are usually generated on their edges and surfaces, requiring further grinding. In existing production methods, stamping and grinding equipment are usually two independent devices, located at different workstations in the workshop. After stamping, operators need to manually move the workpiece from the stamping station to the grinding station, clamp and position it before grinding. After grinding, it needs to be moved to the next process again. There is waiting and turnaround time between the two processes, resulting in a long overall production cycle and low processing efficiency. At the same time, the workpiece is repeatedly clamped and positioned between the stamping and grinding stations, and it is difficult to keep the clamping reference consistent each time, which can easily introduce positioning deviations, causing grinding position offsets or uneven grinding. Moreover, manual handling of forgings also poses risks of bumps and burns, and the labor intensity of operators is high, limiting the capacity improvement of the entire production line.

[0004] In addition, the aluminum shavings and metal dust generated during the grinding process are directly scattered on the workbench and surrounding floor without any simultaneous collection measures. The aluminum shavings are light and have sharp edges, and once scattered, they are easily spread throughout the workshop with the movement of personnel and the vibration of equipment. This not only increases the daily cleaning burden of the workshop, but also poses a safety hazard caused by dust accumulation. When aluminum alloy dust reaches a certain concentration in the air, it may cause a dust explosion when exposed to an open flame. The scattered sharp aluminum shavings may also cut the hands and feet of operators, or mix with the surface of other workpieces to be processed, causing secondary scratches. Some fine dust may also affect respiratory health if inhaled by operators. Summary of the Invention

[0005] To address the aforementioned issues of separate equipment for stamping and grinding processes in traditional aluminum alloy forgings, requiring manual transfer and repeated clamping of workpieces across workstations, resulting in long process turnover times, low processing efficiency, and easy positioning deviations affecting processing quality, as well as significant risks and labor intensity associated with manual operation, and the easy dispersion and diffusion of aluminum dust generated during grinding, leading to a heavy workload for workshop cleaning, poor working environment, and high safety hazards, this application provides a stamping device for processing aluminum alloy forgings.

[0029] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of this application, and not all of the embodiments. Based on the embodiments of this application, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of this application.

[0030] Reference Figure 1-8 This invention provides a stamping device for processing aluminum alloy forgings, including a base 1, a pressure tank 2 above the base 1, an upper mold 3 fixedly connected to the bottom of the pressure tank 2, main hydraulic cylinders 4 vertically mounted at the four corners of the upper mold 3, the bottom ends of the main hydraulic cylinders 4 fixed to the top surface of the base 1, a lower stamping mold 25 positioned directly below the upper mold 3 on the top surface of the base 1, a workpiece pad 101 laid on the top surface of the lower stamping mold 25, a lifting cylinder 26 connected to the bottom of the lower stamping mold 25, a waste collection bin 27 inside the base 1, guide hoods 28 correspondingly mounted on the left and right sides of the lower stamping mold 25, a filter screen 29 inclinedly installed inside the waste collection bin 27, a dust extraction fan 30 mounted on the outside of the base 1, and the dust extraction fan 30 connected to the guide hoods 28 via pipes; the bottom of the upper mold 3... A conveyor rail 7 is arranged on the outer side of the lower stamping die 25. A synchronous belt 10 is mounted on the conveyor rail 7. A servo motor 8 is installed at the corner of the conveyor rail 7. The output end of the servo motor 8 is connected to a rotary table 9. A connecting block 11 is fixedly installed on the synchronous belt 10. A mounting platform 12 is mounted on the upper end of the connecting block 11. A lifting rod 13 is vertically installed through the mounting platform 12. A horizontal moving module 14 is fixedly connected to the lower end of the lifting rod 13. A ball screw 15 is installed inside the horizontal moving module 14. A mounting shell 18 is fixedly installed at the bottom end of the ball screw 15 through a fixing plate 16. A grinding head 24 is detachably installed at the bottom of the mounting shell 18. A main cylinder 23 is mounted on one end of the grinding head 24. A sealing ring 22, a spring 21, a damper 20 and a mounting block 19 are sequentially fitted on the outer side of the main cylinder 23 near the mounting shell 18.

[0031] The equipment base 1 supports the overall structure. The workpiece pad 101 is placed on the top surface of the lower stamping die 25 to place the forging to be processed. The lifting cylinder 26 pushes the lower stamping die 25 up to bring the workpiece closer to the upper die 3. The pressure tank 2 outputs pressure through the upper die 3 to complete the stamping. The main hydraulic cylinder 4 plays a vertical guiding and supporting role when the upper die 3 is raised and lowered. After the stamping is completed, the lifting cylinder 26 drives the lower stamping die 25 down to the grinding height. The servo motor 8 drives the rotary table 9 to rotate. The rotary table 9 drives the synchronous belt 10 to move cyclically along the conveyor guide rail 7. The synchronous belt 10 drives the connecting block 11 and the mounting table 12 to move along the circular track to send the grinding head 24 above the workpiece. The lifting rod 13 descends along the mounting table 12 to bring the grinding head 24 close to the surface of the workpiece. The ball screw 15 moves laterally inside the horizontal moving module 14. The fixed plate 16 moves with the ball screw. The ball screw 15 moves and drives the mounting housing 18 and the grinding head 24 to reciprocate laterally to complete the grinding. During the grinding process, the main cylinder 23 retracts backward with the grinding head 24 under force, and the compression spring 21 generates a rebound force. The damper 20 adopts the RB-2430 type hydraulic damper, which consumes vibration energy by generating resistance through the internal hydraulic oil flowing through the small hole. Together with the spring 21, it automatically adjusts the grinding pressure according to the height of the workpiece surface. The sealing ring 22 moves with the main cylinder 23 to block the debris from entering the mating gap. The mounting block 19 provides a reference surface for the damper 20 to bear force. The metal debris generated by grinding is drawn into the waste collection bin 27 by the dust extraction fan 30 forming a negative pressure in the waste collection bin 27 through the opening of the guide hood 28 and enters the waste collection bin 27. The inclined filter screen 29 blocks the debris and causes it to slide down and accumulate along the inclined surface. The filtered air is discharged by the dust extraction fan 30.

[0032] Stamping and grinding are completed sequentially at the same workstation, which can shorten the processing time by eliminating the need for manual handling of workpieces. The surrounding conveyor rails 7, together with the laterally moving ball screws 15, enable the grinding head 24 to cover the entire surface of the workpiece. The floating structure composed of springs 21 and dampers 20 avoids hard pressure damage to the workpiece or accelerated wear of the grinding head 24. The negative pressure diversion and collection system enables the metal chips to be collected in a directional manner, preventing them from scattering and polluting the environment.

[0033] In a preferred embodiment, the pressurized tank 2 is fixedly mounted on the top surface of the upper mold 3 by a bracket. The top surface of the equipment base 1 is also equipped with an auxiliary hydraulic cylinder 5. The top of the auxiliary hydraulic cylinder 5 abuts against the bottom edge of the upper mold 3. Multiple sets of auxiliary hydraulic cylinders 5 are evenly spaced along the outer periphery of the upper mold 3.

[0034] The pressurizing tank 2 is located on the top surface of the upper mold 3 to output the stamping pressure. The auxiliary hydraulic cylinders 5 are evenly arranged along the outer ring of the upper mold 3. When the upper mold 3 is stamping downwards, the piston rod extends to apply an upward supporting force to the bottom edge of the upper mold 3, and together with the main hydraulic cylinder 4, they share the reaction force generated by the stamping.

[0035] Multiple sets of auxiliary hydraulic cylinders 5 evenly distribute the uneven force on the upper mold 3, reduce the skewing and vibration of the upper mold 3 during stamping, and make the mold move up and down more smoothly.

[0036] In a preferred embodiment, the conveying guide rails 7 are connected end to end to form a closed ring frame structure. The top of the conveying guide rails 7 is fixedly suspended on the bottom surface of the upper mold 3 by several support seats 6. The servo motor 8 is fixedly assembled above the support seats 6. The rotary table 9 and the synchronous belt 10 form a meshing transmission cooperation.

[0037] The conveyor rails 7 are connected end to end to form a closed circular path. The support base 6 is located between the bottom surface of the upper mold 3 and the conveyor rails 7 and serves to hang and fix it. The servo motor 8 drives the rotary table 9 to rotate. The rotary table 9 drives the synchronous belt 10 to circulate along the circular guide rail, which drives the connecting block 11 and the mounting table 12 to complete the position switching in the circumferential direction.

[0038] In a preferred embodiment, the lifting rod 13 can perform vertical lifting and lowering movements along the mounting platform 12. The bottom end of the lifting rod 13 is rigidly fixedly connected to the horizontal moving module 14. The horizontal moving module 14 extends and is arranged in the horizontal direction. The ball screw 15 can achieve lateral translation adjustment inside the horizontal moving module 14.

[0039] The lifting rod 13 extends and retracts vertically along the mounting platform 12, driving the horizontal moving module 14 to rise and fall as a whole, thereby lowering and raising the grinding head 24. The ball screw 15 rotates inside the horizontal moving module 14, driving the slider to move laterally, so that the grinding head 24 moves laterally back and forth along the workpiece surface for grinding.

[0040] In a preferred embodiment, a corrugated sheet 17 is provided between the fixing plate 16 and the mounting shell 18. The corrugated sheet 17 is arranged around the outside of the ball screw 15, and the upper and lower ends of the corrugated sheet 17 are fixedly connected to the fixing plate 16 and the mounting shell 18, respectively.

[0041] The corrugated sheet 17 is arranged around the outside of the ball screw 15. When the ball screw 15 drives the mounting housing 18 to move laterally, the corrugated sheet 17 is stretched or compressed accordingly, always covering the opening gap at the bottom of the horizontal moving module 14.

[0042] In a preferred embodiment, the mounting block 19 is fixedly embedded in the inner cavity of the mounting shell 18, one end of the damper 20 is disposed against the mounting block 19, the other end of the damper 20 is attached to one end of the spring 21, the other end of the spring 21 is against the sealing ring 22, and the sealing ring 22 is sleeved on the outer wall of the end of the main body cylinder 23.

[0043] Mounting block 19 is located inside mounting shell 18 to provide a reference surface for damper 20 to bear force. When grinding head 24 contacts workpiece and is under pressure, main cylinder 23 retracts into mounting shell 18, compressing sealing ring 22 and spring 21 in sequence and pushing damper 20. After spring 21 is compressed, it generates a reverse force to keep grinding head 24 pressed against workpiece. Damper 20 adopts RB-2430 type hydraulic damper, which generates resistance by internal hydraulic oil flowing through small holes to consume vibration energy and absorb impact and vibration during grinding. Sealing ring 22 moves back and forth with main cylinder 23 to maintain end sealing.

[0044] In a preferred embodiment, the lifting cylinder 26 is housed inside the equipment base 1. The top of the piston rod of the lifting cylinder 26 is fixedly connected to the center of the bottom surface of the lower stamping die 25. The lower stamping die 25 can move vertically up and down under the drive of the lifting cylinder 26 to achieve mold closing or demolding with the upper die 3.

[0045] The lifting cylinder 26 is installed inside the equipment base 1. During the stamping stage, the piston rod extends and pushes the lower stamping die 25 to rise so that the workpiece fits with the upper die 3. After the stamping is completed, the piston rod retracts and drives the lower stamping die 25 to descend, and the workpiece moves down and leaves the upper die 3 to complete the separation.

[0046] In a preferred embodiment, the side of the flow guide 28 facing the lower stamping die 25 is an open structure, the bottom of the flow guide 28 is connected to the internal space of the waste collection bin 27 through a pipe, and the filter screen 29 is obliquely arranged below the pipe outlet of the flow guide 28.

[0047] The opening of the flow guide 28 faces the side of the lower stamping die 25 directly opposite the grinding area. The bottom pipe connects downward to the waste collection bin 27. The filter screen 29 is inclined and located below the pipe outlet. After the debris enters the flow guide 28 with the airflow, it falls along the pipe onto the surface of the filter screen 29. After being blocked, it slides down the inclined mesh surface to the bottom of the waste collection bin 27.

[0048] In a preferred embodiment, the suction pipe of the vacuum cleaner 30 is connected to the interior of the waste collection bin 27. When the vacuum cleaner 30 is working, it can create a negative pressure airflow at the opening of the guide hood 28. Metal shavings generated during the grinding operation can enter the interior of the waste collection bin 27 along the airflow through the guide hood 28 and be intercepted and retained by the filter screen 29, thus completing the shavings collection. The suction pipe of the vacuum cleaner 30 is connected to the waste collection bin 27. During operation, it continuously draws out the air in the bin, creating a negative pressure inside the waste collection bin 27 and the guide hood 28. The inward suction airflow generated at the opening of the guide hood 28 draws in the grinding shavings. After the shavings enter the waste collection bin 27 with the airflow, they are blocked by the filter screen 29 and retained. The air passes through the filter screen 29 and is discharged by the vacuum cleaner 30.

[0049] The lifting cylinder 26 is an Airtac SC63×100 standard cylinder with a diameter of 63mm and a stroke of 100mm. The intake direction is controlled by a two-position five-way solenoid valve to extend and retract the piston rod. A PLC output signal energizes the solenoid valve, causing the lifting cylinder 26 to lift the lower stamping die 25 to complete mold closing. De-energization causes the piston rod to retract, lowering the stamping die 25 and demolding it. The vacuum cleaner 30 is a PF125-1 centrifugal fan with a power of 0.75kW and an air volume of 1200m³ / h. It is controlled by an AC contactor. After the grinding head 24 descends to its final position, the PLC outputs a signal to activate the contactor, starting the vacuum cleaner 30 to begin suction. After grinding, it runs for a 10-second delay before disconnecting to remove residual debris. The lifting rod 13 is a DT500 electric push rod with a thrust of 500N and a stroke of 150mm. It has a built-in DC motor with an encoder, and the PLC controls the motor's forward and reverse rotation via pulse signals. The vertical feed and retraction of the lifting rod 13 are fed back to the PLC by the built-in limit switch. The servo motor 8 is a Delta ECMA-C20604RS servo motor with a power of 400W and an ASD-B2 driver. The PLC sends a positioning command through a pulse plus direction signal. After receiving the pulse, the driver drives the servo motor 8 to rotate the rotary table 9 by a specified angle, so that the synchronous belt 10 transports the grinding head 24 to the target circumferential position. After reaching the target position, the driver feeds back a completion signal to the PLC. The main cylinder 23 has a built-in GDZ-65F air-cooled spindle motor with a power of 1.5kW and a maximum speed of 24,000rpm. The speed is adjusted by a frequency converter. The PLC outputs an analog signal to the frequency converter to set the grinding speed according to the workpiece material. The spindle motor drives the grinding head 24 to rotate to complete the surface grinding. After the lifting rod 13 is raised, the PLC outputs a signal to cut off the frequency converter and stop the main cylinder 23.
