[0044] To make the purpose, technical solution and advantages of the present invention clearer, the technical solution of the present invention will be described in detail below. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

The die assembly 3 is arranged on the operating table 1. The die assembly 3 includes a pressing column 31. The pressing column 31 is connected to the output end of the hydraulic press 2. When the hydraulic press 2 is started upward, the hydraulic press 2 drives the pressing column 31 to move upward. When the hydraulic press 2 is started downward, the hydraulic press 2 drives the pressing column 31 to move downward. The bottom of the pressing column 31 is connected to a top die 38. The outer wall of the pressing column 31 is connected to a baffle 32. The outer wall of the pressing column 31 is slidably connected to a movable frame 33. The movable frame 33 is located above the baffle 32. The bottom of the movable frame 33 is connected to two mounting frames 34. The two mounting frames 34 are rotatably connected to rotating shafts 35 respectively. A connecting block 36 is connected between the two rotating shafts 35. The top and bottom surfaces of the connecting block 36 are respectively connected to the upper die 38. 7. The two upper molds 37 are mirror-imaged. A lower mold 39 is installed on the operating table 1. The lower mold 39 is located below the two upper molds 37. Both upper molds 37 are located below the pressure column 31. The pressure column 31 applies downward pressure to the two upper molds 37 and the connecting block 36, so that the upper mold 37 located below is pressed downward. Through cooperation with the lower mold 39, the material on the lower mold 39 is stamped and formed. Two slide seats 310 are installed on the operating table 1. A groove plate 311 is slidably installed on the slide seat 310. A roller 312 is installed on the mounting frame 34. A gear ring 314 is connected to the outer wall of the rotating shaft 35.

One end of the roller 312 away from the mounting frame 34 is connected to the groove plate 31 1, the gear ring 314 meshes with the rack 313 during the movement, and the two rollers 312 slide along the grooves on the two slot plates 311 when they move. When the roller 312 is about to move to the top, the roller 312 slides along the inclined surface above the parallelogram slot, thereby driving the slot plate 311 to move a distance away from the gear ring 314 on the slide seat 310, so that the rack 313 and the gear ring 314 are separated by a distance. When the roller 312 slides downward, the gear ring 314 does not contact the rack 313. When the roller 312 is about to slide to the bottom, the roller 312 slides along the inclined surface below the parallelogram slot, thereby driving the slot plate 311 to reset, so that when the roller 312 slides upward, the gear ring 314 can engage with the rack 313. The connecting block 36 touches the rack 313, so that the connecting block 36 does not rotate when it moves downward, and rotates 180 degrees when it moves upward, so that the upper die 37 that has just been punched is turned over to the top, and the other upper die 37 is turned over to the bottom. The operating table 1 is equipped with a display 320 and a camera 319, and the camera 319 and the display 320 are connected by a signal line. During the turning process of the upper die 37, the camera 319 shoots the upper die 37 and transmits the image data to the display 320. After analysis, the display 320 displays the surface quality data of the upper die 37. When cracks or damage appear inside the upper die 37, the display 320 gives an alarm, and the staff replaces the damaged upper die 37 in time.Four lower guide posts 316 are installed on the lower die 39, and four upper guide posts 315 are installed on the top and bottom surfaces of the connecting block 36 respectively. The outer walls of the four upper guide posts 315 located on the same surface of the connecting block 36 are in contact with the inner walls of the four lower guide posts 316 during movement. When the four upper guide posts 315 located below contact the four lower guide posts 316, the four upper guide posts 315 are respectively sleeved on the outer walls of the four lower guide posts 316, which has the effect of limiting the connection block 36 and the two upper dies 37, thereby preventing the upper dies 37 from shifting during the stamping process; an inner slide block 317 is slidably installed on the inner wall of the connecting block 36, and the inner slide block 317 is installed on the inner wall of the connecting block 36. The top and bottom surfaces of the block 317 are respectively provided with a plurality of punches 318, the plurality of punches 318 on the top surface of the inner slide block 317 are divided into one group, and the plurality of punches 318 on the bottom surface of the inner slide block 317 are divided into another group, the two groups of punches 318 are respectively connected to the inner walls of the two upper molds 37 in a sliding manner, the lower mold 39 is provided with a plurality of punching holes, the plurality of punches 318 in the same group are respectively in contact with the plurality of punching holes on the lower mold 39 during the movement, the plurality of punching holes penetrate the lower mold 39 and the operating table 1, the top mold 38 is in contact with one group of punches 318 during the movement, and when the pressure column 31 is against the upper mold 37 located above, the outer wall of the top mold 38 The top die 38 is fitted with the inner wall of the upper die 37. At this time, the top die 38 is against the multiple punches 318 located above, so that the inner slide block 317 cannot slide in the connecting block 36 temporarily. During the process of the upper die 37 located below stamping the parts, the multiple punches 318 located below apply pressure to the surface of the material, and then cooperate with the multiple punching holes on the lower die 39 to complete the operation of punching holes on the surface of the material. The waste generated by the punching falls to the bottom of the operating table 1 through the punching holes, and the staff regularly cleans the waste. Through the setting of the mold assembly 3, the two upper dies 37 can perform stamping operations alternately to avoid the same upper die 37 from being used for a long time. Repeated operation increases wear and reduces service life. Alternating operation of the two upper molds 37 can also alleviate the increase in the surface temperature of the upper mold 37. During the flipping process of the upper mold 37, the upper mold 37 is monitored in real time through the cooperation of the camera 319 and the display 320. When the upper mold 37 is damaged, it is replaced in time, avoiding the situation where the mold is damaged during continuous operation and the quality of a large number of materials is damaged; through the setting of multiple punches 318, the upper mold 37 can also perform punching operations during the stamping process, reducing the subsequent secondary punching steps, improving work efficiency, and reducing equipment investment costs. ;

An air inlet is arranged on the oil tank 41. The booster rod 42 is slidably connected to the inner wall of the baffle 32. A spring is arranged between the booster rod 42 and the baffle 32. The bottom surface of the movable frame 33 contacts the top surface of the booster rod 42. The oil pipe 43 is located at the pressure column 3 1, two nozzles 44 are respectively located on the inner wall of the top die 38, the booster rod 42 can compress the hydraulic pressure in the oil tank 41, and the oil tank 41 transports the lubricating oil to the two nozzles 44 through the oil pipe 43 by positive pressure, and the two nozzles 44 spray the lubricating oil onto the upper die 37 below to achieve the lubrication effect; through the setting of the oil spraying assembly 4, the two nozzles 44 can spray the lubricating oil on the upper die 37 before the upper die 37 performs the stamping operation, which plays a role in reducing the stamping friction and cooling, reducing the wear of the upper die 37, and improving the material stamping quality.

[0048] Further, see Fig.10 - Fig.11The dust removal component 5 is used to remove dust from the surface of the material. The dust removal component 5 is arranged on the operating table 1. The dust removal component 5 includes a cylinder 52, which is installed on the operating table 1. A pressing plate 51 is installed on one of the rotating shafts 35. The pressing plate 51 contacts the cylinder 52 when moving. An air intake filter element 53 is installed on the cylinder 52. An air intake pipe 54 is connected to the bottom of the cylinder 52. A pressure cylinder 55 is installed at the bottom of the operating table 1 through a bracket. The end of the air intake pipe 54 away from the cylinder 52 is connected to the pressure cylinder 55. The pressure cylinder 55 is connected to the The operating table 1 is connected with an air outlet pipe 56, and a valve seat 57 is installed on the operating table 1. One end of the air outlet pipe 56 away from the pressure cylinder 55 is connected to one side of the valve seat 57, and the other side of the valve seat 57 is connected to an air outlet pipe 510, and an air outlet is arranged on the air outlet pipe 510. The inner wall of the valve seat 57 is slidably connected with a valve core 58. The air in the pressure cylinder 55 is higher than the normal pressure after being compressed, and the valve core 58 is in a closed state, so that the air in the pressure cylinder 55 cannot be released temporarily, thereby achieving the effect of pressurizing the air. The outer wall of the valve seat 57 is rotatably installed with a bracket. The pry bar 59 has one end hinged to the valve core 58, and the other end of the pry bar 59 is connected to the valve seat 57 through a spring. The two upper guide pillars 315 are in contact with the pry bar 59 during the movement, and one of the upper guide pillars 315 contacts the end of the pry bar 59 away from the valve core 58, so that the pry bar 59 uses the lever principle to tilt the valve core 58, so that the valve core 58 slides a distance away from the valve seat 57. At this time, the valve core 58 is in an open state, and the air in the pressure cylinder 55 is transported to the air outlet through the air outlet pipe 56 and the valve seat 57. Tube 510, the air outlet pipe 510 blows compressed air to the material to be stamped through the air outlet to remove dust and debris on the surface of the material; through the setting of the dust removal component 5, the air outlet pipe 56 can clean the dust and impurities on the surface of the material by blowing compressed air before the material contacts the upper mold 37, and at the same time, it also has a certain cooling effect on the upper mold 37 and the lower mold 39, avoiding dust and impurities from affecting the stamping quality, and also avoiding a large amount of impurities attached to the surface of the upper mold 37 to form oil stains, causing the display 320 to misjudge.

[0049] For further information, see Fig.12 - Fig.13, a fixing component 6 is used to fix the stamping material. The fixing component 6 is arranged on the mold component 3. The fixing component 6 includes four rebound rods 61. The four rebound rods 61 are divided into a group of two. A flat plate 62 is installed on the two rebound rods 61 in the same group. The bottom of the flat plate 62 is connected to a buckle plate 63 through a spring. A connecting rod 64 is connected between the two upper guide columns 315 located on the same surface and on the same side of the connecting block 36. The four connecting rods 64 contact the two flat plates 62 respectively during the movement. A rubber strip is arranged on the buckle plate 63, so that the friction between the buckle plate 63 and the surface of the material is large, so that the two buckle plates 63 can temporarily fix the material to avoid the material from shifting during stamping, thereby affecting the product quality. Through the setting of the fixing component 6, before the material is stamped, the two buckle plates 63 can move downward and buckle the material to temporarily fix the material to avoid the material from shifting during stamping, thereby affecting the stamping effect.

[0050] Example 2

[0051] The automobile part stamping method adopts the automobile part stamping die in Example 1, and further comprises the following steps:

[0052] Step 1: Inspect the two upper molds 37 and the lower mold 39 to confirm that the surface quality of the two upper molds 37 and the lower mold 39 is qualified, and start the camera 319 and the display 320;

[0053] Step 2: Add lubricating oil into the oil tank 41;

[0054] Step 3: Place the material on the lower die 39, and avoid tilting the material when placing it;

[0055] Step 4: Start the hydraulic press 2 downward to perform stamping, and after stamping is completed, start the hydraulic press 2 upward;

[0056] Step 5: During the stamping process, the detection data on the display 320 is observed. When the upper die 37 is damaged, the hydraulic press 2 is turned off and the damaged upper die 37 is replaced.

[0057] Step 6: After the stamping is completed, turn off the display 320, the camera 319 and the hydraulic press 2, and clean and maintain the operating table 1, the hydraulic press 2, the mold assembly 3, the oil injection assembly 4, the dust removal assembly 5 and the fixing assembly 6.

[0058] With the above structure, the working principle of this case is that the staff places the material on the lower die 39, and when the hydraulic press 2 is started upward, the hydraulic press 2 drives the pressure column 31 to move upward, and when the hydraulic press 2 is started downward, the hydraulic press 2 drives the pressure column 31 to move downward, and when the pressure column 31 moves, it drives the baffle 32 and the top die 38 to move synchronously. When the pressure column 31 moves from top to bottom, since the baffle 32 supports the bottom of the movable frame 33, the pressure column 31 drives the movable frame 33 and the two mounting frames 34 to move downward through the baffle 32, and the two mounting frames 34 are connected. The two rotating shafts 35 drive the connecting block 36 to move downward, and the connecting block 36 drives the two upper molds 37 to move downward. When the four upper guide pillars 315 located below contact the four lower guide pillars 316, the four upper guide pillars 315 are respectively sleeved on the outer walls of the four lower guide pillars 316, which play a role in limiting the connecting block 36 and the two upper molds 37, and preventing the upper molds 37 from shifting during the stamping process. When the upper mold 37 located below contacts the material, the material resists the upper mold 37 located below, so that the two upper molds 37 and the connecting block 36 are in a state of being pressed. The connecting block 36, the two rotating shafts 35, the two mounting frames 34 and the movable frame 33 temporarily stop moving, at which time the pressure column 31 drives the baffle 32 and the top die 38 to continue to move downward, and the baffle 32 is separated from the contact with the movable frame 33. When the pressure column 31 and the top die 38 contact the upper die 37 located above, the pressure column 31 applies downward pressure to the two upper dies 37 and the connecting block 36, so that the upper die 37 located below is pressed downward, and the material on the lower die 39 is stamped and formed by cooperating with the lower die 39; when the pressure column 31 is against the upper When the upper die 37 is in place, the outer wall of the top die 38 fits with the inner wall of the upper die 37. At this time, the top die 38 resists against the multiple punches 318 located above, so that the inner slider 317 cannot slide in the connecting block 36 temporarily. During the process of the upper die 37 located below stamping the parts, the multiple punches 318 located below exert pressure on the surface of the material, and then cooperate with the multiple punching holes on the lower die 39 to complete the punching operation on the surface of the material. The waste generated by the punching falls to the bottom of the operating table 1 through the punching holes, and the staff regularly cleans the waste;After the stamping is completed, the hydraulic press 2 drives the pressure column 31 to move upward, and the pressure column 31 drives the baffle 32 and the top die 38 to move upward. When the baffle 32 contacts the movable frame 33, the baffle 32 lifts the movable frame 33, and the movable frame 33 drives the connecting block 36 to move upward through the two mounting frames 34 and the two rotating shafts 35. In the process of the two rotating shafts 35 moving upward, the two gear rings 314 on the two rotating shafts 35 will contact the two racks 313 respectively. After contacting the racks 313, the gear rings 314 drive the rotating shafts 35 to rotate. When the rotating shaft 35 rotates 180 degrees, the gear rings 314 and the racks 313 are disengaged, so that when the two rotating shafts 35 drive the connecting block 36 to move upward, the two rotating shafts 35 can also drive the connecting block 36 is rotated 180 degrees, so that the upper die 37 that has just been punched is turned over to the top, and the other upper die 37 is turned over to the bottom. In the process of the two movable frames 33 moving upward, the two rollers 312 move synchronously with the movable frames 33. When the two rollers 312 move, they slide along the slide grooves on the two slot plates 311. When the rollers 312 are about to move to the top, the rollers 312 slide along the inclined surface above the parallelogram slide groove, thereby driving the slot plate 311 on the slide seat 310 to move a distance away from the gear ring 314, so that the rack 313 is separated from the gear ring 314 by a distance. When the rollers 312 slide downward, the gear ring 314 does not contact the rack 313. When the rollers 312 are about to slide to the bottom When the roller 312 slides along the inclined surface below the parallelogram slot, the slot plate 311 is reset, so that when the roller 312 slides upward, the toothed ring 314 can contact the rack 313, so that the connection block 36 does not rotate when it moves downward, and the connection block 36 rotates 180 degrees when it moves upward. After the connection block 36 rotates, the inner slider 317 rotates accordingly. After the inner slider 317 rotates with the connection block 36, it slides downward by its own gravity, so that the multiple punches 318 located below protrude from the inner wall of the upper mold 37 located below. During the flipping process of the upper mold 37, the camera 319 shoots the upper mold 37 and transmits the image data to the display 320. After the display 320 analyzes the image, , the surface quality data of the upper mold 37 is displayed. When cracks or damage appear inside the upper mold 37, the display 320 gives an alarm, and the staff replaces the damaged upper mold 37 in time. Through the setting of the mold assembly 3, the two upper molds 37 can perform stamping operations alternately, avoiding the same upper mold 37 from being repeatedly operated for a long time and aggravating wear and reducing the service life. The alternating operation of the two upper molds 37 can also alleviate the increase in the surface temperature of the upper mold 37. During the turning process of the upper mold 37, the upper mold 37 is monitored in real time through the cooperation of the camera 319 and the display 320. When the upper mold 37 is damaged, it is replaced in time, avoiding the situation where the mold is damaged during continuous operation and the quality of a large number of materials is damaged.By setting up multiple punches 318, the upper die 37 can also perform punching operations during the stamping process, reducing the subsequent secondary punching steps, improving work efficiency, and reducing equipment investment costs. ;

[0059] When the baffle 32 is separated from the movable frame 33, the booster rod 42 is ejected by the elastic force of the spring, and the oil tank 41 draws in some air through the air inlet with a check valve. In the process of the baffle 32 moving upward until it contacts the movable frame 33, the movable frame 33 squeezes the booster rod 42, so that the booster rod 42 compresses the hydraulic pressure in the oil tank 41. The oil tank 41 transports the lubricating oil to the two nozzles 44 through the oil pipe 43 through the positive pressure action. The two nozzles 44 spray the lubricating oil onto the upper mold 37 below to achieve a lubrication effect. Through the setting of the oil spray assembly 4, the two nozzles 44 can spray the lubricating oil on the upper mold 37 before the upper mold 37 performs the stamping operation, which plays a role in reducing the stamping friction and cooling, reducing the wear of the upper mold 37, and improving the material stamping quality.

[0060] When the rotating shaft 35 connected to the pressure plate 51 moves, the rotating shaft 35 drives the pressure plate 51 to move synchronously. When the pressure plate 51 moves downward, it will contact the cylinder 52 and squeeze the cylinder 52 downward. After being squeezed, the cylinder 52 will transport the air to the inside of the pressure cylinder 55 through the intake pipe 54. When the pressure plate 51 moves upward, the cylinder 52 automatically resets and draws air in through the intake filter element 53. The air in the pressure cylinder 55 is higher than the normal pressure after compression, and the valve core 58 is in a closed state, so that the air in the pressure cylinder 55 cannot be released temporarily, thereby achieving the effect of pressurizing the air. When the connecting block 36 moves downward, one of the upper guide pillars 315 contacts the end of the pry rod 59 away from the valve core 58, so that the pry rod 59 uses the lever principle to lift the valve core 58, causing the valve core 58 to slide a distance away from the valve seat 57. At this time, the valve core 58 is in an open state. In the start state, the air in the pressure cylinder 55 is transported to the air outlet pipe 510 through the air outlet pipe 56 and the valve seat 57. The air outlet pipe 510 blows the compressed air to the material to be stamped through the air outlet to remove the dust and debris on the surface of the material. After the connecting block 36 moves upward, the upper guide column 315 is separated from the contact with the pry bar 59, so that the pry bar 59 is reset by the elastic force of the spring. When the pry bar 59 is reset, it drives the valve core 58 to reset, so that the valve core 58 is closed again; through the setting of the dust removal component 5, the air outlet pipe 56 can clean the dust and impurities on the surface of the material by blowing compressed air before the material contacts the upper mold 37, and at the same time, it also has a certain cooling effect on the upper mold 37 and the lower mold 39, so as to avoid dust and impurities affecting the stamping quality, and also avoid more impurities attached to the surface of the upper mold 37 to form oil stains, which leads to misjudgment of the display 320.

[0061] After the staff has placed the material, the edge of the material is located below the two gusset plates 63. When the four upper guide pillars 315 located below move downward, they drive the two connecting rods 64 to move downward. During the downward movement of the two connecting rods 64, they contact the two flat plates 62 and drive the two flat plates 62 to move downward. The two flat plates 62 drive the two gusset plates 63 to move downward through the spring, so that the two gusset plates 63 contact the edge of the material and apply pressure to the material. Since the gusset plates 63 are provided with rubber strips, the friction between the gusset plates 63 and the surface of the material is relatively large, thereby achieving the two gusset plates. 63 temporarily fixes the material to prevent the material from shifting during stamping, thereby affecting the product quality. When the two connecting rods 64 move upward, the two connecting rods 64 break away from the contact with the two flat plates 62, and the two rebound rods 61 drive the two flat plates 62 and the two buckle plates 63 to reset through elastic force, and the staff takes out the stamped material; through the setting of the fixing component 6, the two buckle plates 63 can move downward and buckle the material before stamping, so as to temporarily fix the material and prevent the material from shifting during stamping, thereby affecting the stamping effect.
