Description

Technical Field

[0001] The invention belongs to the technical field of stamping dies, in particular to a continuously feeding hardware stamping die and a stamping process. Background Art

[0002] The continuous feeding hardware stamping die is a highly efficient and automated production equipment. It adopts a continuous die design and can complete a series of different stamping processes in one stroke of the punch press, such as punching, blanking, bending, trimming, drawing, etc.

[0003] In the prior art, metal materials are continuously fed into a mold through an automatic feeding device. The mold consists of an upper mold and a lower mold. The upper mold moves downward under the action of a punch press to perform punching, bending, drawing and other stamping processes. After completing the processing of one station, the conveyor feeds the material one step further for processing at the next station. This cycle is repeated until the processing of all stations is completed to form the required hardware shape and size.

[0004] There are still some problems in the actual application of the above scheme. Although the existing device can effectively complete the stamping work of metal materials, the machine will cause the surface of the mold to be uneven due to material fatigue, deformation, aging or surface wear during long-term use, thereby generating waste with burrs during the stamping process. The burrs of the waste are irregular protrusions. When the waste moves in the vertical waste trough, it will rub against the inner wall of the waste trough. This friction will slow down the movement speed of the waste or even stop it, resulting in the failure of subsequent waste to pass normally. , which will eventually cause blockage, thereby interrupting the production process and reducing production efficiency. In addition, in a dusty factory environment, the stamping oil applied on the surface of the metal material will remain on the waste after stamping and fall into the waste tank with the waste. These stamping oils will not only adhere to the inner wall of the waste tank, but also mix with dust and impurities in the air to form a viscous mixture. These mixtures will adhere to the inner wall of the waste tank for a long time, which will corrode the inner wall of the waste tank, resulting in rust spots, pits and other damage to the inner wall of the waste tank, thereby reducing the service life of the waste tank.

[0005] To this end, the present invention provides a hardware stamping die and stamping process with continuous feeding. Summary of the invention

[0006] In order to make up for the deficiencies of the prior art, at least one technical problem raised in the background technology is solved.

[0007] The technical solution adopted by the present invention to solve the technical problem is as follows: a continuously feeding hardware stamping die of the present invention comprises a stamping device, a conveyor belt is fixedly arranged on the side of the stamping device, the stamping device comprises a fixed frame, a hydraulic cylinder is fixedly connected to the top of the fixed frame, an upper die is fixedly connected to the output end of the hydraulic cylinder, a lower die is fixedly connected to the lower part of the fixed frame, a waste trough is opened inside the lower die, a waste frame is fixedly connected to the bottom of the lower die, and a lifting and adsorption mechanism is arranged inside the stamping device;

[0008] The lifting and adsorption mechanism includes an electric guide rail fixedly arranged at the bottom of the inner cavity of the waste frame, a displacement rod is slidably arranged above the electric guide rail, and a moving column is fixedly arranged on the top of the displacement rod. The movement of the displacement rod drives the moving column to move synchronously, so as to adsorb the waste stuck in the waste trough, shorten the downtime caused by the blockage of the waste trough, and thus improve the work efficiency.

[0009] Preferably, a first protective shell is fixedly connected inside the electric guide rail, a cylinder is fixedly connected through the top of the first protective shell, a connecting block is fixedly connected to the bottom of the cylinder output end, and a displacement rod is rotatably connected to the upper part of the connecting block.

[0010] Preferably, the electric guide rail removes the remaining mechanisms when the waste chute is unloading normally to avoid the situation where the mechanisms block the unloading, and the cylinder can drive the displacement rod to move synchronously.

[0011] Preferably, a first motor is fixedly connected inside the first protective shell, a first rotating wheel is fixedly connected to an output end of the first motor, a transmission belt is transmission-connected to an outer ring surface of the first rotating wheel, and a second rotating wheel is rotationally connected inside the transmission belt.

[0012] Preferably, a protrusion that matches the groove on the outer annular surface of the displacement rod is provided inside the second rotating wheel. The rotation of the second rotating wheel can drive the displacement rod to move synchronously, and at the same time drive the magnetic block to move synchronously. At this time, rotating while lifting can better break the stuck state of the inner wall of the waste trough, thereby improving the efficiency of waste removal.

[0013] Preferably, a rotating scraping mechanism for cleaning the inner wall of the waste tank is arranged inside the lifting and adsorption mechanism, and the rotating scraping mechanism includes a second protective shell, and the second protective shell is fixedly connected to the upper part of the first protective shell.

[0014] Preferably, the rotating scraping mechanism also includes a guide groove, which is opened inside the movable column, an inner cavity is opened inside the movable column, a second motor is fixedly connected to the bottom of the inner cavity of the movable column, the output shaft of the second motor is fixedly connected to the rotating column, an annular rotating plate is fixedly connected to the top of the rotating column, an arc-shaped limiting groove is opened inside the annular rotating plate, a guide column is slidably connected inside the arc-shaped limiting groove, a connecting rod is fixedly connected to the bottom of the guide column, a conical scraping rod is fixedly connected to one end of the connecting rod, and the connecting rod slides inside the guide groove.

[0015] Preferably, the second protective shell is provided with a plurality of groups of grooves matching the size of the conical scraper rod. When the conical scraper rod completes its work, it will be inserted back into the grooves in the second protective shell, thereby scraping off the mixture of stamping oil and dust on the conical scraper rod, thereby improving the cleanliness of the conical scraper rod. The second motor can timely adjust the working state of the rotating scraping mechanism to adapt to different working scenarios.

[0016] A stamping process for a hardware stamping die with continuous feeding, specifically:

[0017] Mold preparation and installation: Design and manufacture the mold according to the shape, size and material properties of the hardware. Then install the manufactured mold on the punching machine and debug it to ensure that the mold can work correctly and stably.

[0018] Material preparation and feeding: Select appropriate metal materials according to the requirements of hardware, cut the metal materials into appropriate sizes and shapes, and then continuously feed the cut materials into the mold through the conveyor belt;

[0019] Stamping process: first adjust the parameters of the hydraulic cylinder to meet the stamping requirements of the hardware, then continuously feed the metal material to the top of the lower die through the conveyor belt, and drive the upper die through the hydraulic cylinder to apply pressure to the metal material to press the metal material into the required hardware shape, at this time the waste will fall through the waste chute;

[0020] Finished product inspection and packaging: First, the stamped hardware is inspected to ensure that the product quality meets the design requirements. Secondly, the qualified hardware is packaged for easy transportation and storage.

[0021] The stamping process is specifically as follows: first, the parameters of the hydraulic cylinder are adjusted to meet the stamping requirements of the hardware; secondly, the metal material is continuously fed to the top of the lower die through the conveyor belt, and the upper die is driven by the hydraulic cylinder to apply pressure to the metal material to press the metal material into the required hardware shape. At this time, the waste material will fall through the waste trough, but in the process of falling, the waste material will be stuck due to burrs on the edges. At this time, the electric guide rail is started to send the magnetic block to the bottom of the waste trough. At this time, the cylinder is started, and the connecting block is driven to move upward through its output shaft. At the same time, the connecting block and the displacement rod rotating on the upper part of the connecting block are driven to move synchronously, thereby driving the moving column and the magnetic block to move synchronously. The first motor is started to drive the first rotating wheel to rotate while moving, and the second rotating wheel is driven to rotate through the transmission belt. Since the second rotating wheel is provided with a convex block matched with the groove on the outer ring surface of the displacement rod, the displacement rod is also driven to rotate while the second rotating wheel rotates, and then the moving column and the magnetic block can be driven to rotate synchronously. At this time, the waste material and the inner wall of the waste trough can be loosened by the lifting of the displacement rod. Since the hardware material for stamping is magnetic, the loosened waste material is sucked by the magnetic block at this time. At this time, the displacement rod, the moving column and the magnetic block are driven to move synchronously through the downward movement of the cylinder output end, so that the waste material stuck in the waste trough can be brought out of the waste trough.

[0022] The beneficial effects of the present invention are as follows:

[0023] The first motor is started by the displacement rod while moving upward, and the first rotating wheel fixed with the output shaft of the first motor rotates synchronously at this time, and drives the transmission belt to transmit while rotating, thereby driving the second rotating wheel to rotate. Since a convex block matched with the groove on the outer ring surface of the displacement rod is provided in the middle part of the second rotating wheel, the displacement rod can be driven to rotate synchronously while the second rotating wheel rotates. At this time, the movable column fixed on the top of the displacement rod will also rise while rotating, thereby driving the magnetic block to move synchronously, and the stuck state of the inner wall of the waste trough and the waste can be better broken by jacking and rotating. Since the waste is a magnetic hardware material, when the waste is not stuck with the waste trough, the waste is adsorbed by the magnetic block and taken out by the downward movement of the cylinder, thereby shortening the downtime caused by the blockage of the waste trough, thereby improving the work efficiency.

[0024] 2. When the present invention enters the waste trough through the moving column, the second motor is started. At this time, the rotating column fixed to the output shaft of the second motor will also rotate, and at the same time drive the annular rotating plate to move synchronously. When the annular rotating plate rotates, it will drive the arc limit groove provided on the annular rotating plate to move synchronously. At this time, the multiple groups of guide columns sliding in the arc limit groove will diffuse outward along the guide of the arc limit groove, thereby driving the connecting rod fixed to the guide column to diffuse outward along the guide of the guide groove, and at the same time drive the conical scraper rod to move in the direction away from the moving column. When the conical scraper rod is in contact with the inner wall of the waste trough, the lifting and adsorption mechanism will drive the rotating scraping mechanism to rotate synchronously, thereby being able to scrape off the mixture of stamping oil and dust attached to the inner wall of the waste trough, thereby reducing the risk of corrosion of the waste trough and extending the service life of the waste trough. At the same time, it can also avoid the situation where the waste cannot fall due to the mixture of stamping oil and dust adhering to the inner wall of the waste trough, thereby further improving the overall working efficiency of the stamping machine.

[0038] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the present invention is further explained below in conjunction with specific implementation methods.

[0039] Embodiment 1

[0040] like Figures 1 to 8 As shown, one embodiment of the present invention is:

[0041] A continuously feeding hardware stamping die, comprising a stamping device 2, a conveyor belt 1 is fixedly arranged on the side of the stamping device 2, the stamping device 2 comprises a fixed frame 201, a hydraulic cylinder 202 is fixedly connected to the top of the fixed frame 201, an upper die 203 is fixedly connected to the output end of the hydraulic cylinder 202, a lower die 204 is fixedly connected to the lower part of the fixed frame 201, a waste trough 205 is opened inside the lower die 204, a waste frame 206 is fixedly connected to the bottom of the lower die 204, and a lifting and adsorption mechanism 3 is arranged inside the stamping device 2;

[0042] The lifting and adsorption mechanism 3 includes an electric guide rail 309 fixedly arranged at the bottom of the inner cavity of the waste frame 206, a displacement rod 304 is slidably arranged above the electric guide rail 309, and a moving column 310 is fixedly arranged on the top of the displacement rod 304. The movement of the displacement rod 304 drives the moving column 310 to move synchronously, so as to adsorb the waste stuck in the waste trough 205, shorten the downtime caused by the blockage of the waste trough 205, and thus improve the work efficiency.

[0043] Specifically, although the existing device can effectively complete the stamping work of metal materials, the machine will cause the surface of the mold to be uneven due to material fatigue, deformation, aging or surface wear during long-term use, thereby generating waste with burrs during the stamping process. The burrs of the waste are irregular protrusions. When the waste moves in the waste trough 205, it will rub against the inner wall of the waste trough 205. This friction will slow down the movement speed of the waste or even stop it, so that the subsequent waste cannot pass normally, and finally cause blockage, which will interrupt the production process and reduce production efficiency.

[0044] Therefore, the present invention solves this problem by setting a certain structure. When it is necessary to stamp the hardware material with magnetism, the hardware material that has completed the previous work is placed on the conveyor belt 1. At this time, the conveyor belt 1 will start and drive the material on its upper part to move toward the waste trough 205 and the upper mold 203. When the hardware material moves to the predetermined position, the hydraulic cylinder 202 fixed on the fixed frame 201 is started. At this time, the output end of the hydraulic cylinder 202 will push the upper mold 203 to move toward the lower mold 204. When the upper mold 203 and the lower mold 204 are against each other, the hardware material will be pressed into the required shape. At this time, the pressed waste will fall into the waste frame 206 through the waste trough 205. However, due to the fatigue, deformation, aging or surface wear of the material during the long-term use of the machine, the mold surface will be uneven, thereby generating waste with burrs during the stamping process. The burrs of the waste are irregular protrusions. When the waste moves in the waste groove 205, it will rub against the inner wall of the waste groove 205. This friction will slow down the movement of the waste or even stop it, so that the subsequent waste cannot pass normally, and finally cause blockage, which will interrupt the production process and reduce production efficiency. Start the electric guide rail 309 to move the lifting and adsorption mechanism 3 to the bottom of the waste trough 205, and drive the movable column 310 fixed to it to move upward through the displacement rod 304 to push the waste stuck inside the waste trough 205, so that the waste and the inner wall of the waste trough 205 are loosened, thereby facilitating the magnetic block 311 to adsorb the waste in the waste trough 205. At this time, the movement of the magnetic block 311 can quickly remove the waste stuck in the waste trough 205, shortening the downtime caused by the blockage of the waste trough 205, thereby improving work efficiency.

[0045] like Figure 3 and Figure 4 As shown, the electric guide rail 309 in this embodiment is fixedly connected to the inside with a first protective shell 301, a cylinder 302 is fixedly connected through the top of the first protective shell 301, a connecting block 303 is fixedly connected to the bottom of the output end of the cylinder 302, and a displacement rod 304 is rotatably connected to the upper part of the connecting block 303.

[0046] Specifically, when material jam occurs inside the waste trough 205, the electric guide rail 309 is started to drive the remaining mechanisms except the electric guide rail 309 to move to the lower part of the waste trough 205. When it moves to the bottom of the waste trough 205, the cylinder 302 is started. At this time, the output shaft of the cylinder 302 will move upward, and at the same time, it will drive the connecting block 303 to move upward synchronously, and then drive the displacement rod 304 to move synchronously. The movement of the displacement rod 304 can drive the mechanism on its top to move upward synchronously.

[0047] like Figure 4 and Figure 5 As shown, in this embodiment, the first protective shell 301 is fixedly connected to the inside with a first motor 305, the output end of the first motor 305 is fixedly connected to a first rotating wheel 306, the outer ring surface of the first rotating wheel 306 is transmission-connected to a transmission belt 307, and the transmission belt 307 is rotationally connected to a second rotating wheel 308 inside.

[0048] Specifically, when the displacement rod 304 is moved upward and the first motor 305 is started, the first rotating wheel 306 fixed to the output shaft of the first motor 305 rotates synchronously, and drives the transmission belt 307 to transmit while rotating, thereby driving the second rotating wheel 308 to rotate. Since a convex block that is adapted to the groove on the outer annular surface of the displacement rod 304 is provided in the middle of the second rotating wheel 308, the displacement rod 304 can be driven to rotate synchronously while the second rotating wheel 308 rotates. The movable column 310 at the top of the displacement rod 304 will also rise and rotate at the same time, thereby driving the magnetic block 311 to move synchronously. The lifting and rotation can better break the stuck state of the inner wall of the waste trough 205 and the waste. Since the waste is a magnetic hardware material, when the waste is not stuck with the waste trough 205, the waste is adsorbed by the magnetic block 311 and taken out by the downward movement of the cylinder 302, thereby shortening the downtime caused by the blockage of the waste trough 205, thereby improving work efficiency.

[0049] like Figure 6 As shown, the lifting and adsorption mechanism 3 of this embodiment is internally provided with a rotating scraping mechanism 4 for cleaning the inner wall of the waste tank 205 , and the rotating scraping mechanism 4 includes a second protective shell 401 , and the second protective shell 401 is fixedly connected to the upper part of the first protective shell 301 .

[0050] like Figure 7 and Figure 8As shown, the rotating scraping mechanism 4 described in this embodiment also includes a guide groove 402, and the guide groove 402 is opened inside the moving column 310, and an inner cavity is opened inside the moving column 310, and a second motor 403 is fixedly connected to the bottom of the inner cavity of the moving column 310, and the output shaft of the second motor 403 is fixedly connected to a rotating column 404, and an annular rotating plate 405 is fixedly connected to the top of the rotating column 404, and an arc-shaped limiting groove 406 is opened inside the annular rotating plate 405, and a guide column 407 is slidably connected inside the arc-shaped limiting groove 406, and a connecting rod 408 is fixedly connected to the bottom of the guide column 407, and a conical scraper rod 409 is fixedly connected to one end of the connecting rod 408, and the connecting rod 408 slides inside the guide groove 402.

[0051] Specifically, when the moving column 310 enters the waste trough 205, the second motor 403 is started. At this time, the rotating column 404 fixed to the output shaft of the second motor 403 will also rotate, and while rotating, it will drive the annular rotating plate 405 to move synchronously. When the annular rotating plate 405 rotates, it will drive the arc-shaped limiting groove 406 provided on the annular rotating plate 405 to move synchronously. At this time, the multiple groups of guide columns 407 sliding inside the arc-shaped limiting groove 406 will spread outward along the guide of the arc-shaped limiting groove 406, thereby driving the connecting rod 408 fixed to the guide column 407 to spread outward along the guide of the guide groove 402, and at the same time drive the conical scraper rod 409 to move away from the moving column 310. When the conical scraper rod 409 is in contact with the inner wall of the waste trough 205, the lifting and adsorption mechanism 3 will drive the rotating scraping mechanism 4 to rotate synchronously, thereby being able to scrape the material attached to the waste trough 20 5, thereby reducing the risk of the waste tank 205 being corroded and extending the service life of the waste tank 205. At the same time, it can also avoid the situation where the waste cannot fall due to the adhesion of the stamping oil and dust mixture to the inner wall of the waste tank 205, further improving the overall working efficiency of the punching machine. When the lifting and adsorption mechanism 3 completes the adsorption work, it will move downward. When the moving column 310 moves out of the waste tank 205, the second motor 403 will rotate in the opposite direction and drive the conical scraper 409 back to the initial state. At this time, the rotating scraper mechanism 4 will also move downward under the drive of the lifting and adsorption mechanism 3, and stop moving when the moving column 310 is inserted into the second protective shell 401. At this time, the conical scraper 409 will be inserted into the groove opened in the second protective shell 401, so that the dirt on the conical scraper 409 can be cleaned, thereby improving the cleanliness of the conical scraper 409.

[0052] Embodiment 2

[0053] like Figures 1 to 8 As shown in the comparative example 1, another embodiment of the present invention is: a stamping process of a hardware stamping die with continuous feeding, the specific steps include:

[0054] Mold preparation and installation: Design and manufacture the mold according to the shape, size and material properties of the hardware. Then install the manufactured mold on the punching machine and debug it to ensure that the mold can work correctly and stably.

[0055] Material preparation and feeding: Select appropriate metal materials according to the requirements of hardware, and cut the metal materials into appropriate sizes and shapes. Then, the cut materials are continuously fed into the mold through the conveyor belt 1;

[0056] Stamping process: first adjust the parameters of the hydraulic cylinder 202 to meet the stamping requirements of the hardware, then continuously feed the metal material to the top of the lower die 204 through the conveyor belt 1, and drive the upper die 203 through the hydraulic cylinder 202 to apply pressure to the metal material to press the metal material into the required hardware shape, and at this time the waste will fall through the waste chute 205;

[0057] Finished product inspection and packaging: First, the stamped hardware is inspected to ensure that the product quality meets the design requirements. Secondly, the qualified hardware is packaged for easy transportation and storage.

[0058] The stamping process is specifically as follows: first, the parameters of the hydraulic cylinder 202 are adjusted to meet the stamping requirements of the hardware; secondly, the metal material is continuously fed to the top of the lower die 204 through the conveyor belt 1, and the upper die 203 is driven by the hydraulic cylinder 202 to apply pressure to the metal material to press the metal material into the required hardware shape. At this time, the waste material will fall through the waste trough 205, but in the process of falling, the waste material will be stuck due to burrs on the edges. At this time, the electric guide rail 309 is started to send the magnetic block 311 to the bottom of the waste trough 205. At this time, the cylinder 302 is started, and the connecting block 303 is driven to move upward through its output shaft. At the same time, the connecting block 303 and the displacement rod 304 rotating on the upper part of the connecting block 303 are driven to move synchronously, and then the moving column 310 and the magnetic block 311 can be driven to move synchronously. At the same time, the first motor 305 is started to drive the first rotating wheel 306 to rotate, and the second rotating wheel 308 is driven to rotate through the transmission belt 307. Since the second rotating wheel 308 is provided with a convex block that is compatible with the outer ring surface groove of the displacement rod 304, the displacement rod 304 is also driven to rotate when the second rotating wheel 308 rotates, and then the movable column 310 and the magnetic block 311 can be driven to rotate synchronously. At this time, the waste can be loosened from the inner wall of the waste trough 205 by the lifting of the displacement rod 304. Since the hardware material for stamping is magnetic, the loosened waste is sucked by the magnetic block 311 at this time. At this time, the output end of the cylinder 302 moves downward to drive the displacement rod 304, the movable column 310 and the magnetic block 311 to move synchronously, so that the waste stuck in the waste trough 205 can be brought out of the waste trough 205.

[0059] Working principle: when material jam occurs inside the waste trough 205, the electric guide rail 309 is started to drive the remaining mechanisms except the electric guide rail 309 to move to the lower part of the waste trough 205. When it moves to the bottom of the waste trough 205, the cylinder 302 is started. At this time, the output shaft of the cylinder 302 will move upward, and at the same time, it will drive the connecting block 303 to move upward synchronously, and then drive the displacement rod 304 to move synchronously. The movement of the displacement rod 304 can drive the mechanism on its top to move upward synchronously.

[0060] When the displacement rod 304 starts the first motor 305 while moving upward, the first rotating wheel 306 fixed to the output shaft of the first motor 305 rotates synchronously, and drives the transmission belt 307 to transmit while rotating, thereby driving the second rotating wheel 308 to rotate. Since the middle part of the second rotating wheel 308 is provided with a convex block adapted to the groove on the outer annular surface of the displacement rod 304, the displacement rod 304 can be driven to rotate synchronously while the second rotating wheel 308 rotates. At this time, the moving column 310 fixed on the top of the displacement rod 304 will also rotate while rising, thereby driving the magnetic block 311 to move synchronously. The stuck state of the inner wall of the waste trough 205 and the waste can be better broken by lifting and rotating. Since the waste is a magnetic hardware material, when the waste is not stuck with the waste trough 205, the waste is adsorbed by the magnetic block 311, and the waste is taken out by the downward movement of the cylinder 302, thereby shortening the downtime caused by the blockage of the waste trough 205, thereby improving the work efficiency.

[0061] When the moving column 310 enters the waste trough 205, the second motor 403 is started. At this time, the rotating column 404 fixed to the output shaft of the second motor 403 will also rotate, and while rotating, it will drive the annular rotating plate 405 to move synchronously. When the annular rotating plate 405 rotates, it will drive the arc-shaped limiting groove 406 provided on the annular rotating plate 405 to move synchronously. At this time, the multiple groups of guide columns 407 sliding inside the arc-shaped limiting groove 406 will spread outward along the guide of the arc-shaped limiting groove 406, thereby driving the connecting rod 408 fixed to the guide column 407 to spread outward along the guide of the guide groove 402, and at the same time drive the conical scraper rod 409 to move away from the moving column 310. When the conical scraper rod 409 fits against the inner wall of the waste trough 205, the lifting and adsorption mechanism 3 will drive the rotating scraping mechanism 4 to rotate synchronously, thereby being able to scrape the material attached to the waste trough 205. The mixture of stamping oil and dust on the wall can be scraped off, thereby reducing the risk of corrosion of the waste trough 205 and extending the service life of the waste trough 205. At the same time, it can also avoid the situation where the waste cannot fall due to the adhesion of the stamping oil and dust mixture to the inner wall of the waste trough 205, further improving the overall working efficiency of the stamping machine. When the jacking and adsorption mechanism 3 completes the adsorption work, it will move downward. When the moving column 310 moves out of the waste trough 205, the second motor 403 will rotate in the opposite direction and drive the conical scraper rod 409 back to the initial state. At this time, the rotating scraper mechanism 4 will also move downward under the drive of the jacking and adsorption mechanism 3, and stop moving when the moving column 310 is inserted into the second protective shell 401. At this time, the conical scraper rod 409 will be inserted into the groove opened in the second protective shell 401, so that the dirt on the conical scraper rod 409 can be cleaned, thereby improving the cleanliness of the conical scraper rod 409.

Then install the manufactured mold on the punching machine and debug it to ensure that the mold can work correctly and stably. Material preparation and feeding: Select appropriate metal materials according to the requirements of hardware, cut the metal materials into appropriate sizes and shapes, and then continuously feed the cut materials into the mold through a conveyor belt (1); Stamping process: firstly, the parameters of the hydraulic cylinder (202) are adjusted to meet the stamping requirements of the hardware, then the metal material is continuously fed to the top of the lower die (204) through the conveyor belt (1), and the upper die (203) is driven by the hydraulic cylinder (202) to apply pressure to the metal material to press the metal material into the required hardware shape, and at this time, the waste material will fall through the waste chute (205); Finished product inspection and packaging: First, the stamped hardware is inspected to ensure that the product quality meets the design requirements. Secondly, the qualified hardware is packaged for easy transportation and storage.

10. The stamping process of a metal stamping die with continuous feeding according to claim 9, characterized in that: The stamping process is specifically as follows: first, the parameters of the hydraulic cylinder (202) are adjusted to meet the stamping requirements of the hardware, and then the metal material is continuously fed to the top of the lower mold (204) through the conveyor belt (1), and the upper mold (203) is driven by the hydraulic cylinder (202) to apply pressure to the metal material to press the metal material into the required hardware shape. At this time, the waste will fall through the waste trough (205), but in the process of falling, the waste will be stuck due to burrs on the edge. At this time, the electric guide rail (309) is started to send the magnetic block (311) to the bottom of the waste trough (205). At this time, the cylinder (302) is started and the connecting block (303) is driven to move upward through its output shaft. At the same time, the connecting block (303) and the displacement rod (304) rotating on the upper part of the connecting block (303) are driven to move synchronously, thereby driving the moving column (310) and the magnetic block (311) to move synchronously. When the first motor (305) is started, the first rotating wheel (306) is driven to rotate, and the second rotating wheel (308) is driven to rotate through the transmission belt (307). Since the second rotating wheel (308) is provided with a protrusion adapted to the groove on the outer annular surface of the displacement rod (304), the displacement rod (304) is also driven to rotate when the second rotating wheel (308) rotates, thereby driving the moving column (310) and the magnetic block (311) to rotate synchronously. At this time, the waste material and the inner wall of the waste trough (205) can be loosened by lifting the displacement rod (304). Since the hardware material for stamping is magnetic, the loosened waste material is sucked by the magnetic block (311). At this time, the output end of the cylinder (302) moves downward to drive the displacement rod (304), the moving column (310) and the magnetic block (311) to move synchronously, thereby being able to bring the waste material stuck in the waste trough (205) out of the waste trough (205).
