[0003] When stamping metal gaskets, the metal gasket to be stamped is usually placed manually in the lower die, and the hydraulic cylinder drives the upper die to move downward to punch a hole in the middle of the metal gasket. Since the metal gasket needs to be removed after stamping, the inner diameter of the lower die is slightly larger than the outer diameter of the metal gasket, which may cause the punched hole to be not in the exact center of the metal gasket, affecting the quality of the finished product. At the same time, the manual placement and removal of the metal gasket consumes a lot of manpower, and the hydraulic cylinder works continuously, that is, the upper die moves back and forth, which requires workers to remove the stamped metal gasket and place a new metal gasket during the upper die moving process.

[0029] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0030] like Figures 1 to 11As shown, the present invention provides a hardware stamping processing device, including a loading mechanism 1, a fixing frame 6, a waste collection bin 11 and a metal gasket 12, the loading mechanism 1 includes a loading platform 101 and a positioning buffer assembly 102, the positioning buffer assembly 102 elastically slides on the top of the loading mechanism 1, and is in an up and down sliding form, the loading platform 101 is supported on the ground by a bracket, the waste collection bin 11 is placed below the loading platform 101 for collecting stamping waste, the metal gasket 12 is stamped on the top of the positioning buffer assembly 102, the fixing frame 6 is placed on the ground and arranged on the outside of the loading platform 101, and also includes an adjusting mechanism 2, the adjusting mechanism 2 is symmetrically arranged at both ends of the bottom of the loading mechanism 1; a limiting mechanism 3, the limiting mechanism 3 slides symmetrically on the loading platform The fixing mechanism 4 is arranged at the bottom of the loading platform 101 and is located on the adjacent side of the adjusting mechanism 2; the connecting air pipe 5 is arranged at the bottom of the loading platform 101 and is used to connect the limiting mechanism 3 and the fixing mechanism 4; the stamping mechanism 7 is arranged just above the positioning buffer assembly 102 and is used to stamp the metal gasket 12; the transmission mechanism 8 is arranged on the inner wall of the fixing frame 6 and is used to push the metal gasket 12 for loading; the feeding mechanism 9 is arranged on one side of the loading platform 101 and is used to store the metal gasket 12 to be processed; the finished product collecting mechanism 10 is arranged on the other side of the loading platform 101 and is used to collect the processed metal gasket 12.

[0031] By placing the metal gasket 12 to be processed inside the feeding mechanism 9, and synchronously driving the transmission mechanism 8 to move through the operation of the stamping mechanism 7, the metal gasket 12 to be processed inside the feeding mechanism 9 moves toward the top of the positioning buffer assembly 102, and the metal gasket 12 to be processed enters the processing station through the extrusion limiting mechanism 3. In the process of extruding the limiting mechanism 3, the adjustment mechanism 2 connected to the bottom of the limiting mechanism 3 can provide a rebound force to the limiting mechanism 3. When the center of the metal gasket 12 passes through the connecting line of the two limiting mechanisms 3 connected to the same adjustment mechanism 2, the two limiting mechanisms 3 move toward each other synchronously, which can squeeze the metal gasket 12, so that the metal gasket 12 quickly reaches the processing station, and is then limited by the two limiting mechanisms 3 on the other side to ensure the stability of the position of the metal gasket 12. At the same time, when the processed metal gasket 12 already exists on the top of the positioning buffer assembly 102, the metal gasket 12 to be processed When the metal gasket 12 moves to the workstation at the top of the positioning buffer assembly 102, it can squeeze the processed metal gasket 12, so that the processed metal gasket 12 moves to the inside of the finished product collecting mechanism 10. Synchronously, when the processed metal gasket 12 moves and its axis passes over the connecting line of the two limiting mechanisms 3 on one side close to the finished product collecting mechanism 10, the two limiting mechanisms 3 on this side move synchronously toward each other, which can quickly make the processed metal gasket 12 leave the workstation, thereby achieving the effect of rapid loading and unloading; and, when the stamping mechanism 7 is working for stamping, the limiting mechanism 3 is compressed along its axial direction. When the limiting mechanism 3 is compressed, the gas can be transported to the inside of the fixing mechanism 4 through the connecting air pipe 5, so that the fixing mechanism 4 stretches along its axial direction, thereby limiting the position of the limiting mechanism 3, ensuring that the metal gasket 12 to be processed can be accurately located at the center of the top of the positioning buffer assembly 102, thereby providing processing accuracy.

[0032] like Figure 5 , Figure 6 As shown, the adjustment mechanism 2 includes a tension spring 201, a first sliding block 202 and a connecting rod 203. The first sliding block 202 is slidably connected to the bottom of the loading platform 101, and the connecting rod 203 is hinged inside the first sliding block 202. The two ends of the tension spring 201 are respectively connected to the tension spring 201 and the first sliding block 202.

[0033] There are two connecting rods 203 and they are distributed up and down. The two connecting rods 203 are respectively hinged on the two limiting mechanisms 3 on the same side, so that the two limiting mechanisms 3 on the same side of the two connecting rods 203 distributed up and down can move toward or away from each other synchronously, so that when the metal gasket 12 moves on the top of the positioning buffer assembly 102, the metal gasket 12 always moves along a straight line that coincides with the center of the top surface of the positioning buffer assembly 102, and then the fixing mechanism 4 squeezes the two limiting mechanisms 3 on the same side respectively located on the two adjusting mechanisms 2, so that the center of the metal gasket 12 overlaps with the center of the positioning buffer assembly 102 in the height direction, thereby realizing the precise positioning of the metal gasket 12.

[0034] like Figure 3 , Figure 6 As shown, the limiting mechanism 3 includes a second sliding block 301, a first connecting tube 302, a positioning tube 303, a first spring 304 and an extrusion tube 305. The second sliding block 301 is slidably connected to the loading platform 101, the first connecting tube 302 is rotatably connected to the middle of the second sliding block 301, the bottom of the second sliding block 301 is hinged to the connecting rod 203, the positioning tube 303 is sleeved on the upper end of the first connecting tube 302, the extrusion tube 305 is sleeved on the upper end of the positioning tube 303, and the first spring 304 is set The punching mechanism 7 is inside the positioning tube 303 and its two ends are respectively connected to the bottom of the inner cavity of the positioning tube 303 and the bottom of the extrusion tube 305, and a ball is arranged on the top of the extrusion tube 305; the punching mechanism 7 includes a hydraulic cylinder 701 and a connecting plate 702, the hydraulic cylinder 701 is installed on the top of the inner side of the fixing frame 6, the connecting plate 702 is fixedly installed on the output shaft of the hydraulic cylinder 701, and a punching head is also installed on the output shaft of the hydraulic cylinder 701, and a sliding groove for the extrusion tube 305 to slide is also opened at the bottom of the connecting plate 702.

[0035] When the hydraulic cylinder 701 is started, it can drive the punch head and the connecting plate 702 to move downward synchronously. During the downward movement, the connecting plate 702 can squeeze the extrusion tube 305, so that the extrusion tube 305 gradually enters the interior of the positioning tube 303, and the ball on the top of the extrusion tube 305 can slide at the bottom of the connecting plate 702, reducing the resistance of the limit mechanism 3 to the horizontal movement. When the punch head contacts the top surface of the metal gasket 12, the telescopic rod formed by the extrusion tube 305 and the positioning tube 303 is compressed to the maximum value. At this time, the metal gasket 12 has also been positioned to the center of the processing station. The punch head continues to move downward, which can squeeze the positioning buffer assembly 102 to move downward into the installation Inside the carrier 101, when the positioning buffer assembly 102 moves down to the maximum value, the top surface of the positioning buffer assembly 102 is coplanar with the top surface of the loading platform 101. Through the design of the positioning buffer assembly 102, it can provide pre-pressure buffering, and at the same time, it can also provide support for the metal gasket 12 to move from the inside of the feeding mechanism 9 to the top of the positioning buffer assembly 102, ensuring that the metal gasket 12 can stably enter the middle of the four positioning tubes 303 when moving. At the same time, the positioning tube 303 is provided with an annular groove that can limit the metal gasket 12, ensuring that the metal gasket 12 will not move in the vertical direction, thereby ensuring the stability of the moving trajectory of the metal gasket 12 when entering the work station.

[0036] like Figures 6 to 9As shown, the fixing mechanism 4 includes a fixing tube 401, a gas injection assembly 402, a connecting frame 403, a sliding plate 404, a fixing assembly 405, a fourth spring 406 and a squeezing column 407. The fixing tube 401 is fixedly installed at the bottom of the loading platform 101, the gas injection assembly 402 is sleeved inside the fixing tube 401, the connecting frame 403 is fixedly installed at one end of the gas injection assembly 402 protruding from the fixing tube 401, and the end of the connecting frame 403 away from the gas injection assembly 402 is slidably connected to the sliding plate 404 through the fixing assembly 405. One end of the fourth spring 406 is connected to The inner wall of the sliding plate 404 and the other end are connected to the inner wall of the connecting frame 403, the extrusion column 407 is installed on the end of the sliding plate 404 close to the gas injection component 402, the connecting air pipe 5 is connected to the fixed pipe 401 and the first connecting pipe 302, and the connecting air pipe 5 is made of rubber; the gas injection component 402 includes a sliding pipe 4021, a positioning frame 4022, a second spring 4023 and a sealing block 4024, the sliding pipe 4021 is sleeved with the fixed pipe 401 and fixedly connected with the connecting frame 403, the positioning frame 4022 is installed inside the sliding pipe 4021, and the positioning frame The second spring 4023 is used to elastically seal one end of the sliding tube 4021. The second spring 4023 connects the positioning frame 4022 and the sealing block 4024. The fixing assembly 405 includes a positioning pin 4051, a third spring 4052 and an extrusion block 4053. The positioning pin 4051 is slidably arranged inside the sliding plate 404 along the length direction of the sliding plate 404. The third spring 4052 is arranged inside the sliding plate 404 and pushes the positioning pin 4051 to connect the connecting frame 403 and the sliding plate 404 through elastic force. The position of the plate 404 is locked, the extrusion block 4053 is slidably connected to the inside of the sliding plate 404 and is located in the sliding direction of the first connecting tube 302 on the loading platform 101, and a through groove is opened in the middle of the positioning pin 4051 to allow the extrusion block 4053 to enter, and the contact surface between the extrusion block 4053 and the positioning pin 4051 is an inclined surface. When the extrusion block 4053 moves along its length direction and enters the through groove in the middle of the positioning pin 4051, the positioning pin 4051 is squeezed by the inclined surface to move to release the lock between the connecting frame 403 and the sliding plate 404.

[0037] During the downward movement of the connecting plate 702, the telescopic rod formed by the extrusion tube 305 and the positioning tube 303 is compressed, and the internal gas is injected into the fixed tube 401 through the connecting gas pipe 5. Since the fourth spring 406 generates elastic force on the sliding plate 404, the extrusion column 407 does not contact the sealing block 4024, that is, the end of the gas injection component 402 close to the connecting frame 403 is sealed. At this time, the injected gas can push the gas injection component 402 to move out of the fixed tube 401 along its axial direction. During the movement, the extrusion block 4053 first contacts the first connecting tube 302. Since the fixing component 405 is provided with two corresponding limiting mechanisms 3 on the same side of the two adjusting mechanisms 2, only when the connecting line of the two limiting mechanisms 3 on the same side of the two adjusting mechanisms 2 is parallel to the long side of the sliding plate 404, the two extrusion blocks 4053 are both pushed, and the extrusion blocks 4 053 drives the positioning pin 4051 to move, and the two positioning pins 4051 are separated from the connecting frame 403. At this time, under the condition that the gas continues to be injected, the sliding plate 404 moves toward the inside of the connecting frame 403, and the extrusion column 407 gradually contacts and squeezes the sealing block 4024, thereby compressing the second spring 4023. The gas is now discharged into the inside of the connecting frame 403 through the fixed tube 401 and discharged through the exhaust holes on the surface of the connecting frame 403 to prevent excessive extrusion; and when the connecting plate 702 moves upward and the limiting mechanism 3 is extended as a whole, the elastic force of the second spring 4023 pushes the sealing block 4024 to seal the port of the sliding tube 4021, and a negative pressure is formed inside the fixed tube 401, causing the gas injection component 402 to gradually retreat into the fixed tube 401. The elastic force provided by the second spring 4023 is sufficient to counteract the pulling force formed by the negative pressure, thereby ensuring that one end of the sliding tube 4021 is in a sealed state.

[0038] like Fig.10 As shown, the transmission mechanism 8 includes a first gear 801, a first tooth plate 802, a second gear 803 and a second tooth plate 804. The first gear 801 and the second gear 803 are fixedly connected and the two rotate on the inner side of the fixed frame 6 through the connecting shaft. The first tooth plate 802 is meshed with the first gear 801, and the second tooth plate 804 is meshed with the second gear 803. The first tooth plate 802 and the second tooth plate 804 are both limited by the fixed frame 6 so that they can only move along their length direction. The first tooth plate 802 is fixedly connected to the connecting plate 702; the feeding mechanism 9 includes a storage bin 901 and a feeding push plate 902. The feeding push plate 902 is slidably connected to the inside of the storage bin 901. The feeding push plate 902 is fixedly connected to the second tooth plate 804. When the feeding push plate 902 is driven by the second tooth plate 804 to move into the storage bin 901, it can push the metal gasket 12 of the bottom layer inside the storage bin 901 to the top of the positioning buffer assembly 102.

[0039] When the connecting plate 702 is driven upward by the hydraulic cylinder 701, the connecting plate 702 synchronously drives the first tooth plate 802 to move, the first tooth plate 802 drives the first gear 801 to rotate, and the first gear 801 drives the second gear 803 fixed thereto to rotate, thereby driving the second tooth plate 804 to move, and when the second tooth plate 804 moves, it drives the feeding push plate 902 to move and then pushes out the metal gasket 12 to be processed, thereby realizing automatic replacement of the processed part. It is worth mentioning that when the connecting plate 702 moves upward, the feeding push plate 902 pushes the metal gasket 12 to be processed into the processing position, and the connecting plate 702 When the connecting plate 702 moves downward, the feeding push plate 902 moves back so that the next metal gasket 12 to be processed falls to the same height as the feeding push plate 902, and when the feeding push plate 902 pushes the metal gasket 12 to be processed so that the axis of the metal gasket 12 to be processed passes the connecting line of the two limiting mechanisms 3, under the joint action of the limiting mechanism 3 and the adjusting mechanism 2, the metal gasket 12 to be processed quickly breaks away from the contact with the feeding push plate 902 and enters the area formed by the four limiting mechanisms 3, that is, the feeding push plate 902 does not need to push the metal gasket 12 to be processed completely into the processing station.

[0040] like Fig.11 As shown, the finished product collection mechanism 10 includes a limiting bin 1001, a collection box 1002 and a protection plate 1003. The limiting bin 1001 and the storage bin 901 are respectively arranged on both sides of the loading platform 101. The collection box 1002 is arranged inside the limiting bin 1001 to collect the stamped metal gaskets 12. The protection plate 1003 is arranged on the top of one end of the loading platform 101 located inside the limiting bin 1001.

[0041] When the processed metal gasket 12 is squeezed out of the processing station by the metal gasket 12 to be processed, when the center of the circle of the processed metal gasket 12 passes over the connecting line of the two limiting mechanisms 3 on the side close to the loading platform 101, the two limiting mechanisms 3 on this side cooperate with the adjusting mechanism 2 at the bottom to quickly squeeze the processed metal gasket 12, so that the metal gasket 12 is bounced into the limiting bin 1001, and finally falls into the collecting box 1002 and is collected. The provided protective plate 1003 serves to protect the adjusting mechanism 2 below.

[0042] The working principle and use process of the present invention:

[0043] Before use, first add a plurality of metal gaskets 12 to be processed into the storage bin 901, then start the hydraulic cylinder 701, the hydraulic cylinder 701 drives the connecting plate 702 to move downward, and performs a stamping without a workpiece. When the hydraulic cylinder 701 moves downward to the maximum value, the metal gasket 12 inside the storage bin 901 falls to the same height as the feeding push plate 902. Then, the hydraulic cylinder 701 moves upward to drive the connecting plate 702 to move upward, thereby driving the feeding push plate 902 to move in the direction close to the positioning buffer assembly 102. During the movement of the feeding push plate 902, it can drive the metal gasket inside the storage bin 901 at the bottom. The metal gasket 12 to be processed in the storage bin 901 is pushed by the feeding push plate 902 to gradually contact and squeeze the two first connecting tubes 302 connected to the same adjusting mechanism 2. The two first connecting tubes 302 move synchronously in opposite directions under the squeezing of the metal gasket 12 to be processed. When the center of the circle of the metal gasket 12 to be processed passes over the connecting line of the two first connecting tubes 302 on this side, the two first connecting tubes 302 on this side cooperate with the adjusting mechanism 2 at the bottom to quickly squeeze the metal gasket 12 to be processed, so that the metal gasket 12 is ejected into the area formed by the four first connecting tubes 302.

[0044] Synchronously, when the connecting plate 702 moves downward, it can squeeze the squeezing tube 305, so that the telescopic rod formed by the squeezing tube 305 and the positioning tube 303 is compressed, and the gas enters the first connecting tube 302 and is transported to the inside of the fixed tube 401 through the connecting gas pipe 5. Since one end of the sliding tube 4021 is sealed by the cooperation of the sealing block 4024 and the second spring 4023, the gas pushes the gas injection assembly 402 to move out of the fixed tube 401 as a whole, and the connecting frame 403 and the sliding plate 404 connected to the sliding tube 4021 are , the fixing assembly 405 and other structures move synchronously. Since the fixing assembly 405 is provided with two groups corresponding to the two limiting mechanisms 3 on the same side respectively located on the two adjusting mechanisms 2, only when the connecting line of the two limiting mechanisms 3 on the same side respectively located on the two adjusting mechanisms 2 is parallel to the long side of the sliding plate 404, that is, the four limiting mechanisms 3 form a rectangle in the horizontal direction, the two extrusion blocks 4053 are both pushed, the extrusion blocks 4053 drive the positioning pins 4051 to move, and the two positioning pins 4051 are both separated from the connecting frame 40 3. At this time, the metal gasket 12 to be processed is stably located at the center of the processing station, that is, the metal gasket 12 to be processed is located at the center of the top surface of the positioning buffer assembly 102. The hydraulic cylinder 701 continues to move downward. Under the condition that the gas continues to be injected, the sliding plate 404 moves toward the inside of the connecting frame 403, and the squeezing column 407 gradually contacts and squeezes the sealing block 4024, thereby compressing the second spring 4023. At this time, the gas is discharged from the inside of the fixed pipe 401 to the inside of the connecting frame 403 and passes through the surface of the connecting frame 403. The gas is discharged from the exhaust hole to prevent over-extrusion. Synchronously, the punch head gradually contacts and squeezes the metal gasket 12 to be processed, so that the metal gasket 12 to be processed moves down synchronously with the positioning buffer component 102. When the positioning buffer component 102 moves down to the maximum value, the top surface of the positioning buffer component 102 and the loading platform 101 and the bottom surface of the metal gasket 12 to be processed are coplanar, and the punch head continues to move to realize the stamping of the metal gasket 12. Synchronously, at this time, the feeding push plate 902 moves in a direction away from the positioning buffer component 102;

[0045] After stamping, the connecting plate 702 moves upward. At this time, the limiting mechanism 3 is stretched as a whole, and negative pressure is formed inside the fixed tube 401. The elastic force provided by the second spring 4023 is sufficient to resist the tensile force formed by the negative pressure, ensuring that one end of the sliding tube 4021 is in a sealed state. Under the action of the negative pressure, the gas injection component 402 gradually retreats to the inside of the fixed tube 401, and the feeding push plate 902, driven by the connecting plate 702 and the transmission mechanism 8, pushes the next metal gasket 12 to be processed to move in the direction of the positioning buffer component 102, and squeezes the processed metal gasket 12. The processed metal gasket 12 is in the waiting state. The processed metal gasket 12 moves toward the limit bin 1001 under the push. When the center of the circle of the processed metal gasket 12 passes over the connecting line of the two limit mechanisms 3 close to one side of the limit bin 1001, the two limit mechanisms 3 on this side cooperate with the adjusting mechanism 2 at the bottom to quickly extrude the processed metal gasket 12, so that the metal gasket 12 is bounced into the loading platform 101 and finally falls into the collecting box 1002 and is collected. The continuous operation of the hydraulic cylinder 701 can achieve the effect of continuous processing, and it is only necessary to fill the metal gasket 12 to be processed into the storage bin 901.
