Description

Technical Field

[0001] The present invention relates to the technical field of metal stamping, and in particular to a metal stamping forming and forging system and method. Background Art

[0002] Metal stamping is a common metalworking method that uses dies and stamping equipment to apply pressure to sheet metal, transforming it into the desired geometric shape. Metal stamping can mass-produce metal parts with excellent repeatability and is widely used in various industries, including automotive, electronics, aerospace, and telecommunications. Metal stamping encompasses the following key processes: Blanking: Blanking is the stamping process used to separate sheet metal, including operations such as punching, blanking, trimming, and sectioning. Bending: Bending is the stamping process used to bend sheet metal along a bend line into a specific angle or shape. Drawing: Drawing is the stamping process used to transform flat sheet metal into various hollow parts or further modify the shape and size of hollow parts. Partial forming: Partial forming is a stamping process that uses various types of localized deformation to alter the shape of a blank or stamped part. It includes operations such as flanging, bulging, leveling, and shaping. Metal stamping offers high production efficiency and low material consumption, making it suitable for large-scale part manufacturing and amenable to mechanization and automation. Stamping can produce parts with a wide range of sizes and complex shapes, exhibiting high strength and rigidity. In addition, stamping processing has the advantages of saving materials and energy and has low cost.

[0003] At present, when a metal plate is stamped to form an arc shape, during the stamping process, the center part of the metal plate that is in contact with the mold undergoes a large deformation under the extrusion of the mold. If cracks are generated in the center part of the metal plate due to the extrusion of the mold, it is currently impossible to detect cracks in the center part of the metal plate during the stamping process, which affects the quality of the products produced by the stamped metal plate and increases the labor burden of the personnel.

[0022] Compared with the prior art, the present invention provides a metal stamping forming and forging system and method, which has the following beneficial effects:

[0023] 1. This metal stamping forming and forging system, when stamping a metal plate, when the lower surface of the metal plate is completely fitted with the inner surface of the lower die, the bottom of the center part of the metal plate is fitted with the upper surface of the detection plate. Before fitting, the limit plate loses its limiting state on the limit rod.

After the stamping is completed, personnel are required to repair and polish the metal plate, which reduces the burden on personnel and ensures the quality of the metal plate after stamping.

[0025] 3. After the metal plate is stamped, the upper die moves upward in the metal stamping forging system.

The stamped metal plate does not need to be taken out by personnel using other equipment, which makes it easier for personnel to take out the stamped metal plate, reduces the burden on personnel, and improves the efficiency of metal plate stamping.

[0026] The parts not involved in the device are the same as the existing technology or can be implemented by using the existing technology. The present invention can detect cracks at the bottom of the center part of the metal plate when the metal plate is stamped.

DETAILED DESCRIPTION

[0038] The technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

Example

[0040] Reference Figure 1-Figure 3 、 Figure 5-Figure 7A metal stamping and forging system includes a workbench 1, the bottom of which is provided with four legs, the top of which is fixedly connected with a lower die 2, and further includes:

[0041] A cylinder 3 is fixedly connected to the top of the workbench 1, an output end of the cylinder 3 is fixedly connected to an upper mold 4, and a liquid tank 5 is fixedly connected to the bottom of the workbench 1;

[0042] A fixed frame 11 is slidably connected to the workbench 1, and a telescopic rod 12 is fixedly connected to the adjacent side of the fixed frame 11. A clamping spring 13 is provided on the outer wall of the telescopic rod 12. One end of the clamping spring 13 is fixedly connected to a clamping block 14. The front end of the clamping block 14 is inclined. The end of the telescopic rod 12 away from the fixed frame 11 is fixedly connected to the clamping block 14. The end of the clamping spring 13 away from the clamping block 14 is fixedly connected to the fixed frame 11. A lifting spring 28 is fixedly connected to the top of the bottom end of the fixed frame 11;

[0043] A detection plate 15 is fixedly connected to the adjacent side of the fixed frame 11. The bottom of the clamping block 14 is slidably connected to the top of the detection plate 15. The bottom of the detection plate 15 is fixedly connected to a plug tube 16. The bottom of the detection plate 15 is fixedly connected to a push frame 29. The top of the detection plate 15 is provided with a liquid spray hole 24.

[0044] A partition 17 is fixedly connected to the inner wall of the detection plate 15, and a through hole 18 is opened on the partition 17. A push plate 27 is fixedly connected to the top of the workbench 1;

[0045] When in use, first push the metal plate into the top of the lower mold 2, and clamp the metal plate through the clamping block 14 and the clamping spring 13, then start the cylinder 3 to move the upper mold 4 downward. When the upper mold 4 moves downward and fits the metal plate, the upper mold 4 moves downward again, which will push the fixing frame 11 to slide downward through the detection plate 15, so that the lifting spring 28 is stretched until the metal plate is completely in contact with the inner surface of the lower mold 2.

[0046] The stamping operation of the metal plate is realized, and during the stamping process, the stability of the metal plate position is guaranteed to prevent the metal plate from being displaced, resulting in the stamped metal plate failing to meet the standards, thereby ensuring the quality of the stamping.

[0047] Reference Figure 1-Figure 3 、 Figure 6 、 Figure 7 , further comprising: a tooth rod 6 fixedly connected to the bottom of the upper mold 4, the outer side wall of the tooth rod 6 meshing with a gear 7, the inner side wall of the gear 7 fixedly connected to a rotating shaft 8, the outer side wall of the rotating shaft 8 fixedly connected to a fan blade 9, the end of the rotating shaft 8 is rotatably connected to a fixed plate 10, and the bottom of the fixed plate 10 is fixedly connected to the top of the workbench 1;

[0048] When the upper mold 4 moves downward, the tooth rod 6 moves downward, driving the gear 7 to rotate, and then driving the fan blade 9 to rotate through the rotating shaft 8, so that the fan blade 9 on one side blows air into the lower mold 2, and the fan blade 9 on the other side exhausts air into the lower mold 2;

[0049] The inner surface of the lower mold 2 is effectively cleaned to prevent impurities from being present on the inner surface of the lower mold 2, which may cause scratches on the lower surface of the metal plate when the metal plate is stamped. After the stamping is completed, personnel are required to repair and polish the metal plate, which reduces the burden on personnel and ensures the quality of the metal plate after stamping.

[0050] Reference Figure 4 、 Figure 7 、 Figure 8 , also includes: a connecting spring 19 fixedly connected to the bottom of the detection plate 15, the bottom of the connecting spring 19 is fixedly connected to the limit plate 20, the limit rod 21 is slidably connected to the limit plate 20, the top of the limit rod 21 is fixedly connected with a push block 22, the outer wall of the partition 17 is slidably connected to the outer wall of the push block 22, the push plate 27 is arranged opposite to the bottom of the limit plate 20, the push block 22 passes through the bottom of the detection plate 15 and is slidably connected to the detection plate 15, the top of the push block 22 is fixedly connected with a detection rod 23, the detection rod 23 is located in the middle position of the spray hole 24, the outer wall of the detection rod 23 is sleeved with a detection spring 25, the top of the detection spring 25 is fixedly connected to the top of the inner wall of the detection plate 15, and the bottom of the detection spring 25 is fixedly connected to the top of the push block 22;

[0051] During the downward movement of the upper mold 4, when the push plate 27 contacts the limit plate 20, the upper mold 4 moves downward again, which will cause the push plate 27 to push the limit plate 20 to move upward, so that the limit plate 20 loses the limit state of the limit rod 21. When the metal plate is stamped, if a crack occurs in the middle of the bottom of the metal plate, the detection rod 23 will enter the crack under the action of the detection spring 25. At this time, the push block 22 will squeeze the indicator between the partitions 17 upward, so that the indicator is sprayed on the crack through the spray hole 24;

[0052] It can mark the cracks in the metal plate, so that personnel can timely observe whether the stamped metal plate has defects, and can also facilitate personnel to repair the stamped metal plate, thus ensuring the quality of metal plate stamping production.

[0053] Reference Figure 1-Figure 3 、 Figure 5 、 Figure 6, also includes: a piston cylinder 32 fixedly connected to the bottom of the workbench 1, the inner wall of the piston cylinder 32 is slidably connected to the piston plate 30, the piston plate 30 passes through the workbench 1 and is slidably connected to the workbench 1, the bottom of the piston plate 30 is fixedly connected to the return spring 31, the bottom of the return spring 31 is fixedly connected to the bottom of the inner wall of the piston cylinder 32, and the outer sides of the piston cylinder 32 are fixedly connected with connecting pipes 26, the connecting pipes 26 pass through the workbench 1 and are fixedly connected to the workbench 1, the end of the connecting pipe 26 away from the piston cylinder 32 is adapted to the plug-in pipe 16, the outer wall of the piston cylinder 32 is fixedly connected to a liquid infusion pipe 33, and the end of the liquid infusion pipe 33 away from the piston cylinder 32 is fixedly connected to the outer wall of the liquid tank 5;

[0054] It should be noted that a liquid level sensor is installed in the piston cylinder 32, and a valve is installed in the liquid filling tube 33. The valve is controlled by the liquid level sensor. When a crack is detected in the bottom center of the stamped metal plate, the indicator is consumed. At this time, the indicator refluxed in the detection plate 15 cannot meet the demand in the piston cylinder 32. The liquid tank 5 will replenish the indicator into the piston cylinder 32 through the liquid filling tube 33. This process is controlled by the sensor to control the valve in the liquid filling tube 33 to perform the liquid filling operation.

[0055] When the upper mold 4 moves downward, in the process of pushing the detection plate 15 downward, the push frame 29 will first contact the piston plate 30, and then the push plate 27 will contact the limit plate 20. When the detection plate 15 moves downward again, the push frame 29 will push the piston plate 30 to slide downward along the inner wall of the piston cylinder 32. When the push frame 29 contacts the piston plate 30, the plug-in tube 16 will just be inserted into the connecting tube 26. The downward sliding of the piston plate 30 will squeeze the indicator in the piston cylinder 32 downward, so that the indicator in the piston cylinder 32 passes through the connecting tube 26 into the plug-in tube 16, and then into the detection plate 15, and then enters between the partitions 17 through the through hole 18, until the detection plate 15 enters the bottom of the lower mold 2 so that the upper surface of the detection plate 15 and the inner surface of the lower mold 2 form a flat arc surface;

[0056] Automatic injection of the indicator is achieved, which facilitates the spraying of the indicator when the detection rod 23 detects cracks in the metal plate.

[0057] In the present invention, the working principle when the upper die 4 needs to rise after the stamping is completed is as follows:

[0058] After the stamping is completed, the cylinder 3 is activated in the reverse direction to move the upper die 4 upward. At this time, the upward movement of the upper die 4 causes the detection plate 15 to lose its downward thrust, and then the fixing frame 11 slides upward under the action of the lifting spring 28, pushing the stamped metal plate out of the lower die 2 through the detection plate 15;

[0059] During this process, due to the upward movement of the detection plate 15, the push frame 29 will lose the pushing force on the piston plate 30. At this time, the piston plate 30 will slide upward under the action of the return spring 31, through the connecting tube 26 and the plug tube 16, to extract all the indicators in the detection plate 15 and re-enter the piston cylinder 32, and at the same time, the limit plate 20 will slide downward under the action of the connecting spring 19, and limit the position of the limit rod 21 from the bottom until the plug tube 16 is extracted from the connecting tube 26. At this time, the piston plate 30 cannot slide upward again, and the limit plate 20 has already limited the position of the limit rod 21 until the detection plate 15 completely pushes out the stamped metal plate;

[0060] At the same time, the tooth rod 6 will drive the gear 7 to rotate, and then drive the fan blades 9 to rotate through the rotating shaft 8, so that the fan blades 9 on one side blow air into the lower mold 2, and the fan blades 9 on the other side draw air into the lower mold 2 to clean the inner surface of the lower mold 2.

[0061] Reference Figures 1-8 , a metal stamping forming and forging method, comprising the following steps:

[0062] Step 1: Place the metal plate between the clamping blocks 14 and clamp it with the clamping blocks 14 and the clamping springs 13;

[0063] First, push the metal plate into the top of the lower die 2 and clamp it with the clamping block 14 and the clamping spring 13;

[0064] Step 2: Start the cylinder 3 to move the upper die 4 downward, and punch the metal plate to form the metal plate;

[0065] The cylinder 3 is activated to move the upper mold 4 downward. When the upper mold 4 moves downward to fit the metal plate, the upper mold 4 moves downward again, which will push the fixing frame 11 to slide downward through the detection plate 15, so that the lifting spring 28 is stretched until the metal plate is completely fitted with the inner surface of the lower mold 2.

[0066] When the upper mold 4 moves downward, the tooth rod 6 will move downward, driving the gear 7 to rotate, and then driving the fan blade 9 to rotate through the rotating shaft 8, so that the fan blade 9 on one side blows air into the lower mold 2, and the fan blade 9 on the other side extracts air into the lower mold 2 to clean the inner surface of the lower mold 2;

[0067] When the upper mold 4 moves downward, in the process of pushing the detection plate 15 downward, the push frame 29 will first contact the piston plate 30, and then the push plate 27 will contact the limit plate 20. When the detection plate 15 moves downward again, the push frame 29 will push the piston plate 30 to slide downward along the inner wall of the piston cylinder 32. When the push frame 29 contacts the piston plate 30, the plug-in tube 16 will just be inserted into the connecting tube 26. The downward sliding of the piston plate 30 will squeeze the indicator in the piston cylinder 32 downward, so that the indicator in the piston cylinder 32 passes through the connecting tube 26 into the plug-in tube 16, and then into the detection plate 15, and then enters between the partitions 17 through the through hole 18, until the detection plate 15 enters the bottom of the lower mold 2 so that the upper surface of the detection plate 15 and the inner surface of the lower mold 2 form a flat arc surface;

[0068] During the downward movement of the upper mold 4, when the push plate 27 contacts the limit plate 20, the upper mold 4 moves downward again, which will cause the push plate 27 to push the limit plate 20 to move upward, so that the limit plate 20 loses the limit state of the limit rod 21. When the metal plate is stamped, if a crack occurs in the middle of the bottom of the metal plate, the detection rod 23 will enter the crack under the action of the detection spring 25. At this time, the push block 22 will squeeze the indicator between the partitions 17 upward, so that the indicator is sprayed on the crack through the spray hole 24;

[0069] Step 3: After the metal plate is stamped, the cylinder 3 is activated to move the upper die 4 upward to its initial position, and the stamped metal plate is removed;

[0070] After the stamping is completed, the cylinder 3 is activated in the reverse direction to move the upper die 4 upward. At this time, the upward movement of the upper die 4 causes the detection plate 15 to lose its downward thrust, and then the fixing frame 11 slides upward under the action of the lifting spring 28, pushing the stamped metal plate out of the lower die 2 through the detection plate 15;

[0071] During this process, due to the upward movement of the detection plate 15, the push frame 29 will lose the pushing force on the piston plate 30. At this time, the piston plate 30 will slide upward under the action of the return spring 31, through the connecting tube 26 and the plug tube 16, to extract all the indicators in the detection plate 15 and re-enter the piston cylinder 32, and at the same time, the limit plate 20 will slide downward under the action of the connecting spring 19, and limit the position of the limit rod 21 from the bottom until the plug tube 16 is extracted from the connecting tube 26. At this time, the piston plate 30 cannot slide upward again, and the limit plate 20 has already limited the position of the limit rod 21 until the detection plate 15 completely pushes out the stamped metal plate;

[0072] At the same time, the tooth rod 6 will drive the gear 7 to rotate, and then drive the fan blades 9 to rotate through the rotating shaft 8, so that the fan blades 9 on one side blow air into the lower mold 2, and the fan blades 9 on the other side draw air into the lower mold 2 to clean the inner surface of the lower mold 2. Example

[0073] Reference Figure 5 、 Figure 9 、 Figure 10 A metal stamping and forging system further includes: a gear compression pump 34 installed inside the fixed plate 10, one end of the gear compression pump 34 is fixedly connected to a thick pipe 35, and the end of the gear compression pump 34 away from the thick pipe 35 is fixedly connected to a thin pipe 36, the thin pipe 36 is wound around the outer wall of the connecting pipe 26 and passes through the lower die 2, the thick pipe 35 passes through the lower die 2, the thick pipe 35 is fixedly connected to one side of the fixed plate 10, and the thin pipe 36 is fixedly connected to the side of the fixed plate 10 away from the thick pipe 35, the gear compression pump 34 is fixedly connected to the end of the rotating shaft 8 and is driven by the rotating shaft 8;

[0074] It should be noted that the thick pipe 35, the thin pipe 36 and the gear compression pump 34 are all filled with refrigerant;

[0075] When the rotating shaft 8 rotates, the gear compression pump 34 is activated, so that the refrigerant in the gear compression pump 34 on one side flows from the thick pipe 35 to the thin pipe 36, and the refrigerant in the gear compression pump 34 on the other side flows from the thin pipe 36 to the thick pipe 35. The refrigerant flowing from the thick pipe 35 to the thin pipe 36 will be heated due to the compression of the gear compression pump 34. At this time, since the thin pipe 36 is wrapped around the connecting pipe 26, the temperature of the indicator flowing through the connecting pipe 26 will be heated. The refrigerant flowing from the thin pipe 36 to the thick pipe 35 will be cooled due to the pressure reduction of the refrigerant by the gear compression pump 34.

[0076] The indicator flowing through the connecting pipe 26 is heated, so that the fluidity of the pigment in the indicator is increased, the activity of the pigment is increased, and the pigment can better show the color when marking, which is convenient for personnel to observe. The refrigerant flowing from the thin pipe 36 to the thick pipe 35 will cool the lower mold 2 to prevent the stamping mold from accumulating a large amount of heat that cannot be dissipated after working for a long time, so that the heat will affect the subsequent material processing and will also conduct the heat to the surface of the material to cause burns to the workers, thereby ensuring the quality of subsequent material processing and providing a certain degree of protection for the workers.
