Description

Technical Field

[0001] The present invention relates to the technical field of metal stamping processing, and particularly relates to a high-quality metal stamping and forging device and method. Background Art

[0002] Stamping is a forming process that applies external forces to plates, strips, tubes, profiles, etc. by a press and a die, causing plastic deformation or separation to obtain workpieces (stamped parts) with the required shape and size. Stamping and forging belong to plastic processing (or pressure processing) and are collectively called forging and pressing. The blanks for stamping are mainly hot-rolled and cold-rolled steel plates and steel strips.

[0003] After retrieval, the patent with application number 202210313986.2 discloses "a metal sheet stamping and forming process", and this process includes the following steps: Step 1, screening the processing raw materials of the sheet and adding the qualified raw materials into a hot melt machine for hot melt treatment.

[0004] However, in the above patent, when a groove is stamped on a metal sheet, the groove part will deform first, which will cause the two sides of the metal sheet to gradually warp. Due to the lack of a horizontal pulling force on the warped area, when the warped area gradually comes into contact and presses against the upper stamping plate, bending is likely to occur. When stamping the bent part, wrinkles are very likely to occur, thus unable to ensure the high-quality stamping of the metal sheet. Summary of the Invention

[0005] The purpose of the present invention is to solve the problem in the prior art that when a groove is stamped on a metal sheet, the groove part will deform first, which will cause the two sides of the metal sheet to gradually warp. Due to the lack of a horizontal pulling force on the warped area, when the warped area gradually comes into contact and presses against the upper stamping plate, bending is likely to occur. When stamping the bent part, wrinkles are very likely to occur, thus unable to ensure the high-quality stamping of the metal sheet, and to propose a high-quality metal stamping and forging device and method.

[0006] To achieve the above purpose, the present invention adopts the following technical solution:

Spring one is fixedly installed on the outer sides of the guide rods. The upper and lower ends of spring one are fixedly connected to the support frame and the magnetic frame respectively.

[0011] Preferably, a screw rod is threadedly installed on the fixed plate. The lower end of the screw rod is rotatably installed on the L-shaped plate. Gears are fixedly installed on the upper ends of the screw rods. Magnetic racks are engaged with the front ends of the gears.

[0015] Preferably, connecting pipes are provided at the rear ends of the nozzle plates. An airbag is provided at the rear end of the connecting pipe. The upper and lower ends of the airbag are fixedly connected to the fixed plate and the L-shaped plate respectively. And the nozzle plate is internally communicated with the inside of the airbag through the connecting pipe.

[0016] Preferably, spring three is fixedly installed on the upper end of the nozzle plate. The upper end of spring three is fixedly connected to the L-shaped plate.

[0017] Preferably, extrusion plates are fixedly installed at the upper ends of the third connecting rods. An elastic member is provided below the extrusion plates, and the upper end of the elastic member is fixedly connected to the support.

[0018] A method for a high-quality metal stamping and forging device, the specific steps are as follows:

[0019] Step 1: Lower the fixed plate to squeeze the airbag, and the gas is ejected through the connecting pipe and the nozzle plate to uniformly remove and spray the debris and impurities adhering to the L-shaped plate and the fixed plate.

[0020] Step 2: Lower the stamping plate to drive the support frame, guide rod, first spring, magnetic frame, and pressing roller to descend synchronously to press the metal thin plate.

[0021] Step 3: Fix the two ends of the metal thin plate on the L-shaped plate through the fixed plate and the L-shaped plate to provide a pulling force on the two ends of the metal thin plate, ensuring that the two ends of the metal thin plate will not bend and bulge.

[0022] Step 4: Push the shaping plate, the third connecting rod, and the extrusion plate to quickly descend and reset through the fourth spring. The shaping plate is convenient for tamping the stamping plate after mold closing.

[0023] Compared with the prior art, the beneficial effects of the present invention are:

[0024] 1. In the present invention, start the hydraulic cylinder to drive the stamping plate to descend. The stamping plate cooperates with the groove plate to stamp the metal thin plate, which is convenient for processing the metal thin plate into a groove shape. When the stamping plate descends, it will also drive the support frame to descend synchronously. The support frame drives the guide rod, the first spring, the magnetic frame, and the pressing roller to descend synchronously. The lower end of the pressing roller is lower than the lower end of the stamping plate. Therefore, the pressing roller will first contact the metal thin plate on the groove plate and press the metal thin plate. As the stamping plate continues to descend, the first spring is squeezed, and the pressing roller is convenient for pressing the two sides of the metal thin plate, preventing the two sides of the metal thin plate from warping when stamping the groove of the metal thin plate, and being restricted by the descent of the stamping plate, resulting in the bending of the two sides of the metal thin plate. Thus, the situation of wrinkles appearing on the two sides of the metal thin plate during subsequent stamping is avoided, and the high-quality stamping of the metal thin plate is improved.

[0025] 2. In the present invention, when the magnetic frame descends to the side where the two magnetic racks approach each other, a magnetic repulsive force is generated on the magnetic racks, thereby pushing the two magnetic racks to slide in a direction away from each other. The magnetic racks drive the gear to rotate, and the gear drives the screw rod to rotate on the L-shaped plate. The screw rod drives the two fixed plates to slide and descend on the L-shaped plate, facilitating the fixation of both ends of the metal thin plate on the L-shaped plate. The provided iron blocks facilitate the attraction of the magnetic racks, ensuring that the magnetic racks do not slide naturally and guaranteeing the stable clamping force of the fixed plates. When a groove is stamped in the middle of the metal thin plate, the two sides of the metal thin plate will move towards the middle. At this time, the two L-shaped plates, the first connecting rod, and the connecting plate will move closer to each other, compressing the second spring, facilitating the provision of a pulling force on both ends of the metal thin plate and ensuring that the two ends of the metal thin plate do not bend and bulge, thereby again playing a good role in improving the high-quality stamping of the metal thin plate.

[0026] 3. In the present invention, when the two connecting plates move closer to each other, they will squeeze the limit block, causing the limit block to drive the second connecting rod to slide upward on the cross plate until the connecting plate passes over the lower end of the limit block and the connecting plate separates from the limit block. When reaching the side where the limit blocks approach each other, under the action of gravity, the limit block and the second connecting rod slide downward, and the connecting plate fits with the limit block to limit one end of the connecting plate that moves away from each other. After the metal thin plate is stamped, the worker pushes the two magnetic racks to reset, and further drives the fixed plate to move upward and reset through the gear and the screw rod, releasing the two ends of the metal thin plate. Then, the two second connecting rods and the limit blocks are pulled upward in sequence to separate the limit block from the connecting plate. Under the action of the second spring, the first connecting rod, the connecting plate, and the L-shaped plate are pushed to reset, causing the L-shaped plate to separate from the two ends of the metal thin plate. Since the two L-shaped plates do not separate synchronously when separating, the provided two limit blocks facilitate the effective limitation of the non-detached L-shaped plate and the fixed plate on the other side when one side of the L-shaped plate and the fixed plate are separated from one end of the metal thin plate, preventing the continuous provision of a strong pulling force on one side of the metal thin plate under the action of the second spring, resulting in the deformation and scrapping of the metal thin plate, thereby improving the stamping quality of the metal thin plate.

[0027] 4. In the present invention, when the fixed plate slides and descends on the L-shaped plate, it will also squeeze the airbag, and the gas is ejected through the connecting pipe and the nozzle plate. Moreover, when the fixed plate descends, it will also drive the nozzle plate to slide upward on the L-shaped plate by means of wire rope traction, compressing the third spring, which is beneficial to making the gas ejected from the nozzle plate evenly remove and spray off the debris and impurities adhering to the L-shaped plate and the fixed plate, avoiding the situation where the debris and impurities adhering to the L-shaped plate and the fixed plate cause unstable clamping of the metal thin plate.

[0028] 5. In the present invention, when the stamping plate and the support frame descend, they will also drive the shaping plate, connecting rod three, spring four and the extrusion plate to descend synchronously. The extrusion plate will gradually contact the elastic member and be resisted by the elastic member, driving the extrusion plate, connecting rod three and the shaping plate to hang in the air and slide on the support frame, compressing spring four. When the stamping plate and the groove plate are closed, the pressure of spring four reaches the maximum. At this time, the elastic member will gradually deform until it disengages from the extrusion plate. At this time, under the action of spring four, the shaping plate, connecting rod three and the extrusion plate are pushed to quickly descend and reset. The shaping plate is convenient for tamping the stamping plate after closing the mold, which plays a good auxiliary effect on the shaping of the metal thin plate, and further improves the stamping quality of the metal thin plate.

[0041] Refer to Figures 1-7, A high-quality metal stamping and forging device, including a base 1, a bracket 2 is fixedly installed at the upper end of the base 1, a groove plate 3 is fixedly installed in the middle of the upper end of the base 1, a stamping plate 4 is arranged above the groove plate 3, a hydraulic cylinder 5 is fixedly installed at the upper end of the stamping plate 4, and the hydraulic cylinder 5 is fixedly installed on the bracket 2; There is also an anti-wrinkle mechanism for preventing wrinkles from appearing during the stamping of metal sheets. The anti-wrinkle mechanism includes pressing rollers 6 arranged symmetrically left and right on the lower side of the stamping plate 4. Magnetic frames 7 are rotatably installed on the outer sides of the pressing rollers 6. Guide rods 8 are fixedly installed in the middle of the upper ends of the magnetic frames 7. L-shaped plates 11 are arranged at the left and right sides of the groove plate 3. Fixed plates 12 are slidably installed at the ends of the L-shaped plates 11 close to each other. The upper ends of the guide rods 8 penetrate and are slidably installed with a support frame 9, and the lower end of the support frame 9 is fixedly installed on the stamping plate 4. Spring one 10 is fixedly installed on the outer sides of the guide rods 8, and the upper and lower ends of the spring one 10 are respectively fixedly connected to the support frame 9 and the magnetic frame 7. Screws 13 are threadedly installed on the fixed plates 12, the lower ends of the screws 13 are rotatably installed on the L-shaped plates 11, gears 14 are fixedly installed at the upper ends of the screws 13, magnetic racks 15 are engaged with the front ends of the gears 14, the lower ends of the magnetic racks 15 are slidably installed on the L-shaped plates 11, and iron blocks 16 are fixedly installed on the inner sides of the left and right ends of the bracket 2 corresponding to the magnetic racks 15. Connecting rods one 17 are fixedly installed at the ends of the L-shaped plates 11 away from each other. The ends of the connecting rods one 17 away from each other penetrate and are slidably installed on the bracket 2. Connecting plates 18 are fixedly installed at the ends of the connecting rods one 17 away from each other. Spring two 19 is sleeved on the outer sides of the connecting rods one 17, and the two ends of the spring two 19 are respectively fixedly connected to the bracket 2 and the connecting plate 18. Limit blocks 20 are arranged on the upper sides of the connecting plates 18. Connecting rods two 21 are fixedly installed at the upper ends of the limit blocks 20. The upper ends of the connecting rods two 21 penetrate and are slidably installed with a cross plate 22, and the cross plate 22 is fixedly installed at the left and right ends of the bracket 2;

[0042] During operation, the molten liquid metal after melting is cooled and formed in a mold to obtain a metal sheet. Then, the metal sheet is placed on the groove plate 3. The hydraulic cylinder 5 is started to drive the stamping plate 4 to descend. The stamping plate 4 and the groove plate 3 cooperate to stamp the metal sheet, facilitating the processing of the groove shape on the metal sheet. When the stamping plate 4 descends, it will also drive the support frame 9 to descend synchronously. The support frame 9 drives the guide rod 8, the first spring 10, the magnetic frame 7, and the pressing roller 6 to descend synchronously. The lower end of the pressing roller 6 is lower than the lower end of the stamping plate 4. Therefore, the pressing roller 6 will first contact the metal sheet on the groove plate 3 and press the metal sheet. As the stamping plate 4 continues to descend, the first spring 10 is compressed, and the pressing roller 6 is convenient for pressing both sides of the metal sheet, preventing the two sides of the metal sheet from warping when the groove is stamped on the metal sheet and being restricted by the descent of the stamping plate 4, resulting in the bending of both sides of the metal sheet, thereby avoiding the occurrence of wrinkles on both sides of the metal sheet during subsequent stamping, and further improving the high-quality stamping of the metal sheet. When the magnetic frame 7 descends to one side where the two magnetic racks 15 approach each other, a magnetic repulsive force is generated on the magnetic racks 15, thereby pushing the two magnetic racks 15 to slide in a direction away from each other. The magnetic racks 15 drive the gear 14 to rotate. The gear 14 drives the screw 13 to rotate on the L-shaped plate 11. The screw 13 drives the two fixing plates 12 to slide and descend on the L-shaped plate 11, facilitating the fixation of both ends of the metal sheet on the L-shaped plate 11. The provided iron block 16 is convenient for attracting the magnetic racks 15, ensuring that the magnetic racks 15 will not slide naturally and guaranteeing the stable clamping force of the fixing plates 12. When a groove is stamped in the middle of the metal sheet, the two sides of the metal sheet will move centrally towards the middle. At this time, the two L-shaped plates 11, the first connecting rod 17, and the connecting plate 18 will move towards each other, compressing the second spring 19, facilitating the provision of a pulling force on both ends of the metal sheet, ensuring that both ends of the metal sheet will not bend and bulge, thereby further playing a good role in improving the high-quality stamping of the metal sheet. When the two connecting plates 18 move towards each other, they will squeeze the limiting block 20, causing the limiting block 20 to drive the second connecting rod 21 to slide upward on the cross plate 22 until the connecting plate 18 passes below the lower end of the limiting block 20. The connecting plate 18 and the limiting block 20 are separated from each other. When reaching one side where the limiting blocks 20 approach each other, under the action of gravity, the limiting block 20 and the second connecting rod 21 slide downward, and the connecting plate 18 and the limiting block 20 are mutually attached, limiting one end of the connecting plate 18 away from each other. After the metal sheet is stamped, the staff pushes the two magnetic racks 15 to reset. Furthermore, it will also drive the fixing plates 12 to move upward and reset through the gear 14 and the screw 13, releasing both ends of the metal sheet. Then, the two second connecting rods 21 and the limiting blocks 20 are pulled upward in sequence, separating the limiting blocks 20 from the connecting plates 18. Under the action of the second spring 19, the first connecting rod 17, the connecting plate 18, and the L-shaped plate 11 are pushed to reset, causing the L-shaped plate 11 to separate from both ends of the metal sheet. Since the two L-shaped plates 11 do not separate synchronously when separating,Therefore, by providing the limiting blocks 20 on both sides, when separating the L-shaped plate 11 and the fixing plate 12 on one side from one end of the metal thin plate, it is convenient to effectively limit the L-shaped plate 11 and the fixing plate 12 on the other side that have not been disassembled, preventing a strong pulling force from being continuously applied to one side of the metal thin plate under the action of the second spring 19, resulting in deformation and scrapping of the metal thin plate, thereby improving the stamping quality of the metal thin plate.

[0043] As an embodiment of the present invention, an auxiliary mechanism is further provided for assisting in removing residual debris on the L-shaped plate 11 and assisting in tamping and forming after the stamping plate 4 is stamped. The auxiliary mechanism includes a nozzle plate 23 slidably mounted at the front end of the L-shaped plate 11, and a shaping plate 29 that is disposed in a left-right symmetric manner and is fitted and abutted against the upper end of the stamping plate 4. Link rods three 30 are fixedly mounted on the upper ends of the shaping plates 29. Springs four 31 are sleeved on the outer sides of the link rods three 30. Connecting pipes 24 are provided at the rear ends of the nozzle plates 23. An airbag 25 is provided at the rear end of the connecting pipe 24. The upper and lower ends of the airbag 25 are fixedly connected to the fixing plate 12 and the L-shaped plate 11 respectively, and the nozzle plate 23 is internally communicated with the inside of the airbag 25 through the connecting pipe 24. A spring three 26 is fixedly mounted on the upper end of the nozzle plate 23. The upper end of the spring three 26 is fixedly connected to the L-shaped plate 11. A steel wire rope 27 is fixedly mounted on the upper end of the nozzle plate 23. The other end of the steel wire rope 27 is fixedly connected to the fixing plate 12. A pulley 28 is fixedly mounted on the L-shaped plate 11 corresponding to the steel wire rope 27. Pressing plates 32 are fixedly mounted on the upper ends of the link rods three 30. An elastic member 33 is provided below the pressing plate 32. The upper end of the elastic member 33 is fixedly connected to the bracket 2;

[0044] During operation, when the fixing plate 12 slides down on the L-shaped plate 11, it will also squeeze the airbag 25, and the gas will be ejected through the connecting pipe 24 and the nozzle plate 23. When the fixing plate 12 descends, it will also pull the nozzle plate 23 to slide up on the L-shaped plate 11 through the steel wire rope 27, compressing the third spring 26, which is beneficial to making the gas ejected by the nozzle plate 23 evenly remove and spray down the debris and impurities adhering to the L-shaped plate 11 and the fixing plate 12, avoiding the situation that the debris and impurities adhering to the L-shaped plate 11 and the fixing plate 12 cause unstable clamping of the metal sheet. When the stamping plate 4 and the support frame 9 descend, they will also drive the shaping plate 29, the third connecting rod 30, the fourth spring 31 and the pressing plate 32 to descend synchronously. The pressing plate 32 will gradually contact the elastic member 33 and be resisted by the elastic member 33, driving the pressing plate 32, the third connecting rod 30 and the shaping plate 29 to hang in the air and slide on the support frame 9, compressing the fourth spring 31. When the stamping plate 4 is closed with the groove plate 3, the pressure of the fourth spring 31 reaches the maximum. At this time, the elastic member 33 will gradually deform until it disengages from the pressing plate 32. At this time, under the action of the fourth spring 31, the shaping plate 29, the third connecting rod 30 and the pressing plate 32 are pushed to quickly descend and reset. The shaping plate 29 is convenient for tamping the stamping plate 4 after closing the mold, which plays a good auxiliary effect on the shaping of the metal sheet, and further improves the stamping quality of the metal sheet.

[0045] A method for a high-quality metal stamping and forming forging device is as follows:

[0046] Step 1: By lowering the fixing plate 12, the airbag 25 is squeezed, and the gas is ejected through the connecting pipe 24 and the nozzle plate 23 to evenly remove and spray down the debris and impurities adhering to the L-shaped plate 11 and the fixing plate 12;

[0047] Step 2: By lowering the stamping plate 4, the support frame 9, the guide rod 8, the first spring 10, the magnetic frame 7 and the pressing roller 6 are driven to descend synchronously to press the metal sheet;

[0048] Step 3: The two ends of the metal sheet are fixed on the L-shaped plate 11 by the fixing plate 12 and the L-shaped plate 11, providing a pulling force on the two ends of the metal sheet to ensure that the two ends of the metal sheet will not bend and bulge;

[0049] Step 4: The shaping plate 29, the third connecting rod 30 and the pressing plate 32 are pushed to quickly descend and reset by the fourth spring 31, and the shaping plate 29 is convenient for tamping the stamping plate 4 after closing the mold.

[0050] Working principle:

[0051] When the present invention is in use, the molten liquid metal after melting is cooled and formed in a mold to obtain a metal thin plate. Then, the metal thin plate is placed on the groove plate 3, and the hydraulic cylinder 5 is started to drive the stamping plate 4 to descend. The stamping plate 4 and the groove plate 3 cooperate to stamp the metal thin plate, facilitating the processing of the groove shape on the metal thin plate. When the stamping plate 4 descends, it will also drive the support frame 9 to descend synchronously. The support frame 9 drives the guide rod 8, the first spring 10, the magnetic frame 7, and the pressing roller 6 to descend synchronously. The lower end of the pressing roller 6 is lower than the lower end of the stamping plate 4. Therefore, the pressing roller 6 will first contact the metal thin plate on the groove plate 3 and press the metal thin plate. As the stamping plate 4 continues to descend, the first spring 10 is squeezed, and the pressing roller 6 is convenient for pressing both sides of the metal thin plate, preventing the two sides of the metal thin plate from warping when the groove is stamped on the metal thin plate and being restricted by the descent of the stamping plate 4, resulting in the bending of the two sides of the metal thin plate, thereby avoiding the wrinkling of the two sides of the metal thin plate during subsequent stamping, and further improving the high-quality stamping of the metal thin plate. When the magnetic frame 7 descends to the side where the two magnetic racks 15 are close to each other, a magnetic repulsive force is generated on the magnetic racks 15, thereby pushing the two magnetic racks 15 to slide in a mutually separated direction. The magnetic racks 15 drive the gear 14 to rotate, and the gear 14 drives the screw rod 13 to rotate on the L-shaped plate 11. The screw rod 13 drives the two fixed plates 12 to slide and descend on the L-shaped plate 11, facilitating the fixation of the two ends of the metal thin plate on the L-shaped plate 11. The arranged iron block 16 is convenient for attracting the magnetic racks 15, ensuring that the magnetic racks 15 will not slide naturally and guaranteeing the stable clamping force of the fixed plate 12. When the groove is stamped in the middle of the metal thin plate, the two sides of the metal thin plate will move centrally towards the middle. At this time, the two L-shaped plates 11, the first connecting rod 17, and the connecting plate 18 will move towards each other, compressing the second spring 19, facilitating the provision of a pulling force on the two ends of the metal thin plate and ensuring that the two ends of the metal thin plate will not bend and bulge, thereby once again playing a good role in improving the high-quality stamping of the metal thin plate. When the two connecting plates 18 move towards each other, they will squeeze the limiting block 20, causing the limiting block 20 to drive the second connecting rod 21 to slide upward on the cross plate 22 until the connecting plate 18 passes over the lower end of the limiting block 20, and the connecting plate 18 and the limiting block 20 are separated from each other. When reaching the side where the limiting blocks 20 are close to each other, under the action of gravity, the limiting block 20 and the second connecting rod 21 slide downward, and the connecting plate 18 and the limiting block 20 are mutually attached, limiting one end of the connecting plate 18 that is away from each other. After the metal thin plate is stamped, the staff pushes the two magnetic racks 15 to reset, and then will also drive the fixed plate 12 to move upward and reset through the gear 14 and the screw rod 13, releasing the two ends of the metal thin plate. Then, the two second connecting rods 21 and the limiting blocks 20 are successively pulled upward to separate the limiting blocks 20 from the connecting plate 18. Under the action of the second spring 19, the first connecting rod 17, the connecting plate 18, and the L-shaped plate 11 are pushed to reset, causing the L-shaped plate 11 to separate from the two ends of the metal thin plate. Since the two L-shaped plates 11 do not separate synchronously when separating,Therefore, through the arranged limiting blocks 20 on both sides, when separating one side of the L-shaped plate 11 and the fixed plate 12 from one end of the metal thin plate, it is convenient to effectively limit the L-shaped plate 11 and the fixed plate 12 on the other side that have not been disassembled, preventing a strong pulling force from being continuously provided to one side of the metal thin plate under the action of the second spring 19, which may cause deformation and scrapping of the metal thin plate, thereby improving the stamping quality of the metal thin plate. When the fixed plate 12 slides and descends on the L-shaped plate 11, it will also squeeze the airbag 25, and the gas is ejected through the connecting pipe 24 and the nozzle plate 23. Moreover, when the fixed plate 12 descends, it will also traction and pull the nozzle plate 23 to slide and rise on the L-shaped plate 11 through the steel wire rope 27, compressing the third spring 26, which is beneficial to making the gas ejected by the nozzle plate 23 evenly remove and spray off the debris and impurities adhering to the L-shaped plate 11 and the fixed plate 12, avoiding the situation that the debris and impurities adhering to the L-shaped plate 11 and the fixed plate 12 cause unstable clamping of the metal thin plate. When the stamping plate 4 and the support frame 9 descend, they will also drive the shaping plate 29, the third connecting rod 30, the fourth spring 31 and the pressing plate 32 to descend synchronously. The pressing plate 32 will gradually contact the elastic member 33 and be resisted by the elastic member 33, driving the pressing plate 32, the third connecting rod 30 and the shaping plate 29 to be suspended and slide on the support frame 9, compressing the fourth spring 31. When the stamping plate 4 is combined with the groove plate 3, the pressure of the fourth spring 31 reaches the maximum. At this time, the elastic member 33 will gradually deform until it separates from the pressing plate 32. At this time, under the action of the fourth spring 31, the shaping plate 29, the third connecting rod 30 and the pressing plate 32 are pushed to quickly descend and reset. The shaping plate 29 is convenient for tamping the combined stamping plate 4, playing a good auxiliary effect on the shaping of the metal thin plate, and further improving the stamping quality of the metal thin plate.
