Abstract
Description
Technical Field
[0001] This invention relates to the field of stamping die technology, and more specifically, to a high-speed stamping die for aluminum discs. Background Technology
[0002] Aluminum discs are circular metal materials made from aluminum alloy using stamping dies through a stamping process. When stamping aluminum discs with existing dies, the stamping process often involves applying pressure to one side, resulting in the aluminum disc being subjected to stress on one side. Under these conditions, the stress on one side of the aluminum disc is greater than that on the other side. As the stamping pressure continues to be applied, the uneven stress on the aluminum disc will cause stress diffusion, leading to tearing at the stamping edge and affecting the regularity of the stamping edge.

It should be understood that such data can be interchanged where appropriate for the embodiments of the invention described herein.

[0025] To make the objectives and advantages of the present invention clearer, the present invention will be further described below with reference to embodiments; it should be understood that the specific embodiments described herein are merely for explaining the present invention and are not intended to limit the present invention.
[0026] Please see Figures 1-6 As shown, a high-speed stamping die for aluminum discs includes an upper locking plate 1. A pad 102 is fixedly installed in the middle of the lower surface of the upper locking plate 1. A stamping plate 2 is fixedly installed in the middle of the lower surface of the pad 102. An inverted "T"-shaped positioning post 201 is fixedly installed at each of the four corners of the lower surface of the stamping plate 2. An upper punch 204 is fixedly installed on both sides of the middle of the lower surface of the stamping plate 2. A pressing post 203 is fixedly installed on the lower part of both sides of the outer surface of the stamping plate 2. A pressing plate 3 is movably installed below the stamping plate 2. The other end of the positioning post 201 is movably inserted through the pressing plate 3. The other end of the pressing post 203 is movably inserted into and connected to the pressing plate 3. A compression spring 202 is movably sleeved in the middle of the outer surface of both the positioning post 201 and the pressing post 203.
[0027] It should be noted that by connecting and fixing the upper locking plate 1, the pad plate 102, and the stamping plate 2 together, the assembly of the upper module can be completed. At the same time, the upper locking plate 1 is connected to the stamping equipment by using the assembly hole 101 and the fixing bolt. By setting the positioning column 201 and the compression spring 202, when the stamping plate 2 is close to the stamping table 401 for stamping operation, the positioning column 201 can push the pressing plate 3 to make extrusion contact with the stamping table 401 in advance. Thus, the pressing plate 3 can extrude and fix the aluminum material placed on the stamping table 401 to ensure the stability of the aluminum material stamping aluminum disc.
[0028] Secondly, when the pressing plate 3 is already in contact with the stamping table 401, as the pressing plate 2 continues to move closer to the stamping table 401, the pressing plate 2 will continuously apply pressure to the compression spring 202 sleeved on the outer surface of the positioning post 201. At this time, the compression spring 202 will undergo compression deformation under pressure, and the elastic restoring effect of the compression spring 202 under deformation will further apply pressure to the pressing plate 3, thereby ensuring the stability of the contact between the pressing plate 3 and the stamping table 401.
[0029] Meanwhile, as the stamping plate 2 continues to approach the stamping table 401, it will push the positioning post 201 to align with the positioning hole 402 and extend inward to ensure that the stamping plate 2 can contact the pressing plate 3 in the stamping state. When the stamping plate 2 and the pressing plate 3 are in contact, the upper punch 204 will extend from the inside of the guide sleeve 302 to the outside to form aluminum discs on the aluminum material placed on the stamping table 401.
[0030] The lower surface of the pressing plate 3 has four corner holes 301 in the middle. A guide sleeve 302 is fixedly installed through the middle of the lower surface of the pressing plate 3. Openings are opened on both sides of the lower surface of the guide sleeve 302. The punching end of the upper punch 204 extends into the opening of the guide sleeve 302. The front and rear ends of the lower surface of the pressing plate 3 have storage grooves 303. The front and rear ends of the inner surface of the storage groove 303 are provided with a shaft. The storage groove 303 is hinged to two sets of leveling frames 304 through the outer surface of the shaft. The two sets of leveling frames 304 are arranged in an inverted "V" shape. The inner surface of the two sets of leveling frames 304 is provided with a shaft. The two sets of leveling frames 304 are movably sleeved with a tension spring 305 through the outer surface of the shaft.
[0031] It should be noted that by setting the mating hole 301, when the pressing plate 3 is pressed down and comes into contact with the stamping table 401, the mating hole 301 is fitted onto the outer surface of the mating pin 403, thereby limiting the pressing plate 3 to ensure that it will not shift during the stamping process of the stamping plate 2, and further improving the pressing stability of the pressing plate 3 relative to the stamping table 401. By setting the guide sleeve 302, the upper punch 204 can be separated from the pressing plate 3 to reduce the frictional resistance when the upper punch 204 passes through the pressing plate 3, and ensure that the stamping of the upper punch 204 is smooth.
[0032] Secondly, when the pressing plate 3 descends near the stamping table 401, the leveling frame 304 set on the lower surface of the pressing plate 3 will first press the plate 3 into contact with the aluminum material placed on the stamping table 401. Since the leveling frame 304 is set in an inverted "V" shape, when the leveling frame 304 contacts the aluminum material, it will unfold to both sides as the pressing plate 3 presses down. During the unfolding process, the aluminum material can be pressed and flattened to ensure that the aluminum material is in a flat state and can be pressed and fixed by the pressing plate 3. When the leveling frame 304 unfolds to both sides, it will stretch and unfold the tension spring 305. When the pressing plate 3 rises away from the stamping table 401, the leveling frame 304 can be lifted synchronously and detached from the contact state with the aluminum material. At this time, the leveling frame 304 will be in a state of no force. Under this condition, the tension spring 305 in the stretched state can use its own restoring elasticity to reset and contract, thereby driving the unfolded leveling frame 304 to reset, so as to facilitate the subsequent leveling of the aluminum material.
[0033] A lower locking plate 4 is provided below the pressing plate 3. The upper locking plate 1 and the lower locking plate 4 have mounting holes 101 spirally opened at the four corners of their upper surfaces. A stamping table 401 is fixedly installed in the middle of the upper surface of the lower locking plate 4. The four corners of the upper surface of the stamping table 401 have positioning holes 402 that match the positioning pins 201. The four corners of the middle of the upper surface of the stamping table 401 have protruding and fixedly installed T-shaped docking pins 403. The middle of the lower surface of the stamping table 401 has a groove. The middle of the upper surface of the stamping table 401 has funnel-shaped stamping holes 404 on both sides.
[0034] It should be noted that the lower locking plate 4 can be fixedly connected to the stamping equipment through the assembly hole 101. It is used for stamping aluminum material into aluminum discs through the stamping table 401. The positioning hole 402 on the stamping table 401 is used for positioning and extending the positioning post 201. When the positioning post 201 extends into the positioning hole 402, the stamping plate 2 can move closer to the pressing plate 3. At the same time, when the pressing plate 3 is in contact with the stamping table 401, the mating pin 403 will be inserted into the mating hole 301 to ensure the tight contact between the pressing plate 3 and the stamping table 401. The stamping hole 404 is provided for stamping aluminum discs from aluminum sheet material.
[0035] The punching hole 404 is connected to the groove in the middle of the lower surface of the punching table 401. The front and rear ends of the middle of the inner surface of the groove are provided with a shaft. The punching table 401 is movably hinged to the outer surface of the shaft and a movable plate 5 is installed. A support block 501 is fixedly installed on the middle of the upper surface of one side of the movable plate 5. A lower punch 502 is fixedly installed on the outer surface of the support block 501. The lower punch 502 is located in the punching hole 404. The middle of the outer surface of the movable plate 5 is inclined. Both sides of the outer surface of the movable plate 5 are parallel. The support block 501 is inclined relative to the movable plate 5. The other side of the movable plate 5 extends to the outside of the punching table 401. An inclined movable groove 503 is opened through the middle of the front end of the movable plate 5 on the outer side.
[0036] It should be noted that by opening a groove on the lower surface of the stamping table 401, space can be provided for the installation and movement of the movable plate 5. Since the middle of the outer surface of the movable plate 5 is inclined and both sides of the outer surface of the movable plate 5 are parallel, the other side can be controlled to tilt up while one side of the movable plate 5 is pressed. When the pressing plate 3 contacts the stamping table 401 and the stamping plate 2 moves towards the pressing plate 3, the pressing column 203 will press down synchronously with the stamping plate 2. In this case, the side of the movable plate 5 extending outside the stamping table 401 will be pressed down by the pressing column 203 in the pressed state. At this time, the side of the movable plate 5 with the support block 501 will tilt up, thereby driving the lower punch 502 sleeved on the outer surface of the support block 501 to tilt up synchronously. At the same time, the tilting of the side of the movable plate 5 with the support block 501 is achieved by the pressing column 203 pressing the other side, so the tilting force of the support block 501 is equal to the pressing force of the pressing column 203.
[0037] Since the support block 501 is inclined relative to the movable plate 5, and the middle part of the outer surface of the movable plate 5 is inclined, when the movable plate 5 is tilted and tends to be horizontally parallel, the inclined support block 501 will gradually tend to be vertical relative to the punching hole 404.
[0038] Since the stamping hole 404 and the groove on the stamping table 401 are interconnected, the lower punch 502 located in the stamping hole 404 will tend to be vertical in the longitudinal direction relative to the stamping hole 404 as the support block 501 is raised. In this case, the support block 501 raised to the vertical position can provide support for the stamping part of the aluminum plate, so as to provide reverse stress supply relative to the upper punch 204, thereby maintaining balance with the stamping stress carried by the upper punch 204, so as to avoid the phenomenon of one-sided force on the aluminum disc during stamping. At the same time, the lower punch 502 sleeved on the outer surface of the support block 501 will work with the upper punch 204 to stamp and shear the aluminum disc, thereby avoiding the effect of tearing at the stamping edge of the aluminum disc, thus improving the regularity of the stamping edge of the aluminum disc. The debris generated during the stamping and shearing process can fall into its interior through the stamping hole 404.
[0039] An airbag 6 is fixedly installed at the rear end of the upper surface of the lower locking plate 4. An air inlet is provided at the middle of the front end of the outer surface of the airbag 6. An air inlet one-way valve 602 is fixedly installed on the inner surface of the air inlet of the airbag 6. An exhaust port is provided at the middle of the rear end of the outer surface of the airbag 6. An exhaust one-way valve 601 is fixedly installed on the inner surface of the exhaust port of the airbag 6. A groove communicating with the stamping hole 404 is opened at the lower rear end of the outer surface of the stamping table 401. A slag shovel 603 is fixedly inserted into the inner surface of the groove of the stamping table 401. The slag shovel 603 is connected to the air inlet of the airbag 6. A pressure plate 604 is fixedly installed on the upper surface of the airbag 6. Control rods 605 are fixedly inserted into the lower parts of both sides of the outer surface of the pressure plate 604. The other end of the control rod 605 is slidably inserted into the movable groove 503.
[0040] It should be noted that, since the other end of the control lever 605 is slidably inserted into the movable slot 503, and the movable slot 503 is located on the side of the movable plate 5 extending outward from the stamping table 401, when the side of the movable plate 5 with the movable slot 503 is pressed down by the pressing column 203, the movable slot 503 will drive the control lever 605 to move down synchronously, thereby controlling the pressure plate 604 to press down. When the pressure plate 604 is pressed down, the gas in the airbag 6 can be squeezed out through the exhaust one-way valve 601. At this time, the airbag 6 will be in a negative pressure state. When the movable plate 5 is not pressed by the pressing column 203 on one side of the movable groove 503, the movable groove 503 can be raised, thereby driving the control rod 605 to control the pressure plate 604 to be raised synchronously. The pressure exerted by the pressure plate 604 on the airbag 6 can be released. Since the airbag 6 is made of rubber material and has an elastic reset effect, the airbag 6 can reset and rebound, thereby drawing in external gas through the intake one-way valve 602. The gas flow direction in the airbag 6 can be controlled by setting the intake one-way valve 602 and the exhaust one-way valve 601.
[0041] Since the air intake one-way valve 602 is connected to the slag storage shovel 603, and the slag storage shovel 603 is inserted into the groove and connected to the stamping hole 404, when the airbag 6 draws in external gas, it can extract the gas in the stamping hole 404 through the slag storage shovel 603. During the extraction process, the stamping debris in the stamping hole 404 can flow with the airflow into the slag storage shovel 603 for storage. At this time, the debris in the slag storage shovel 603 can be cleaned periodically to achieve the effect of cleaning the stamping debris.
[0042] In use, the upper locking plate 1 and the lower locking plate 4 are first assembled into modules and then fixedly connected to the stamping equipment. After the modules are installed, the aluminum plate is placed through the stamping table 401. The width of the aluminum plate must match the lateral spacing between the mating pins 403. After the aluminum plate is placed, the stamping equipment connected to the upper locking plate 1 is started. At this time, the stamping equipment can control the module set on the upper locking plate 1 to press down. During the pressing process, the pressing plate 3 will first move towards the stamping table 401. When the pressing plate 3 approaches the stamping table 401... At 01, the leveling frame 304 set on the lower surface of the pressing plate 3 will first press the plate 3 into contact with the aluminum material placed on the stamping table 401. Since the leveling frame 304 is set in an inverted "V" shape, when the leveling frame 304 comes into contact with the aluminum material, it will unfold to both sides as the pressing plate 3 presses down. During the unfolding process, the aluminum material can be pressed and flattened to ensure that the aluminum material is in a flat state to accept the pressing and fixing of the pressing plate 3. At this time, as the pressing plate 3 continues to descend, it can fit against the upper surface of the stamping table 401 to press and fix the aluminum material plate.
[0043] Secondly, after the pressing plate 3 contacts the stamping table 401, the stamping equipment connected to the locking plate 1 will control the locking plate 1 to continuously press down. At this time, the stamping plate 2 will press down towards the pressing plate 3. During the pressing process, the upper punch 204 set on the lower surface of the stamping plate 2 will extend from the inside of the guide sleeve 302 to the outside to stamp the aluminum plate fixed on the stamping table 401 into aluminum discs. During the pressing process of the stamping plate 2 pressing down towards the pressing plate 3, the pressing columns 203 set on both sides of the stamping plate 2 will press down synchronously with the stamping plate 2 until... When the stamping plate 2 and the pressing plate 3 come into contact, the pressing column 203 can press the side of the movable plate 5 with the movable groove 503. At this time, the movable plate 5 can control the side with the support block 501 to tilt up, thereby driving the lower punch 502 sleeved on the outer surface of the support block 501 to tilt up synchronously. The support block 501 tilted up to the vertical state provides support for the stamping part of the aluminum plate. At the same time, the lower punch 502 sleeved on the outer surface of the support block 501 and the upper punch 204 will jointly perform upper and lower side stamping and shearing to form the aluminum disc.
[0044] The debris generated during the stamping and shearing process can fall into the interior of the stamping hole 404. When the side of the movable plate 5 with the movable groove 503 is pressed down by the pressing column 203, the movable groove 503 will drive the control rod 605 to move down synchronously, thereby controlling the pressure plate 604 to press down. When the pressure plate 604 is pressed down, the gas in the airbag 6 can be squeezed out through the exhaust one-way valve 601. At this time, the airbag 6 will be in a negative pressure state. When the side of the movable plate 5 with the movable groove 503 is no longer pressed by the pressing column 203, the movable groove 503 can be raised, thereby driving the control rod 605 to control the pressure plate 604 to rise synchronously. The pressure plate 604 presses down on the airbag 6. The pressure is then relieved. Since the airbag 6 is made of rubber and has an elastic restoring effect, the airbag 6 can then return to its original position and rebound, thereby drawing in external gas through the one-way valve 602. Since the one-way valve 602 is connected to the slag shovel 603, and the slag shovel 603 is inserted into the groove and connected to the punching hole 404, when the airbag 6 draws in external gas, it can draw in the gas in the punching hole 404 through the slag shovel 603. During the drawing process, the punching debris in the punching hole 404 can flow with the airflow into the slag shovel 603 for storage. At this time, the debris in the slag shovel 603 can be cleaned periodically to achieve the effect of cleaning the punching debris.
