[0002] The metal part stamping technology is a common means in the metal part processing process, and in the stamping process, the corresponding stamping mode needs to be adjusted according to the toughness of the metal part material and the stress generated during stamping. Some special-shaped materials usually need to be stamped by multiple stamping devices in sections to ensure the forming quality of the metal part. However, this stamping mode requires more devices and more stamping steps, and human intervention may be required during the stamping process, so that integrated forming cannot be achieved. Before stamping the metal part, lubricating oil is usually sprayed on the surface of the die to reduce the friction generated during stamping and improve the durability of the die. However, due to the difference in types of the die, the human spraying method is usually used, and the uniform distribution of the lubricating oil in the die cannot be guaranteed during the spraying process. At the same time, during the stamping process, the die generates heat, and repeated high-strength stamping of the die can cause the heat in the die to be not released in time, thereby easily causing damage to the die.

[0038] S3: With the cooperation of the hydraulic cylinder one 31 driving the upper die 33 and the hydraulic cylinder two 51 driving the lower die 54, the metal plate is gradually pressed into a metal part according to the pre-set stamping times.

[0039] By adopting the above scheme: this way, the special-shaped metal part can be stamped into shape at one time on one device, without using multiple stamping devices for step-by-step stamping, reducing the stamping steps, improving the stamping efficiency of the metal part, and without human intervention during the stamping process.

[0040] As shown in Figure 5 , Figure 6 , Figure 8 and Figure 9 , the metal part stamping and forming device comprises a machine base 1, a control system 2, a stamping mechanism 3, a pushing mechanism 5 and a feeding mechanism 7;

[0041] The control system 2 is arranged on the machine base 1, the stamping mechanism 3 is arranged above the machine base 1, the pushing mechanism 5 is arranged below the machine base 1, and the feeding mechanism 7 is arranged on the front of the machine base 1:

[0042] The stamping mechanism 3 includes a hydraulic cylinder 31, which is mounted on the top of the machine base 1. The output end of the hydraulic cylinder 31 is connected to a connecting frame 32 located inside the machine base 1. The bottom of the connecting frame 32 is fixed with an upper die 33 via bolts. The internal fixed sleeve of the upper die 33 is provided with a set of heat-conducting strips 35. The internal fixed sleeve of the connecting frame 32 is provided with a set of heat-conducting strips 35. The heat-conducting strips 35 abut against the heat-conducting strips 34. The other end of the heat-conducting strips 35 extends to the outside of the connecting frame 32.

[0043] The pushing mechanism 5 includes a second hydraulic cylinder 51, which is installed at the bottom of the base 1. The output end of the second hydraulic cylinder 51 is connected to a mounting bracket 52 located in the base 1. The top of the mounting bracket 52 is connected to a mounting plate 53.

A one-way valve 2 74 is provided inside the circular hole 73. Cotton smears 75 are connected to the upper and lower parts of the inner side of the feeding box 71 and one side of the cotton smears 75 faces the one-way valve 2 74.

An infrared sensor 710 is installed above the front side of the feeding box 71, and an infrared receiver 711 is installed below the front side of the feeding box 71.

[0045] The above scheme is adopted: the metal sheet to be stamped is inserted into the interior of the feed box 71, so that the upper and lower parts of the metal sheet are in contact with the connecting tube 45. When the sheet is inserted, the sheet will block the light source of the infrared sensor 710. At this time, the infrared receiver 711 will not be able to receive infrared. The control system 2 controls the electric telescopic rod 712 to start, driving the fixed block 713 and the double-headed piston 77 to move a section toward the interior of the oil replenishing barrel 76. Then, pressure can be applied to the oil body inside the feed box 71 and the circular hole 73, and the one-way valve 74 can be opened to push the oil body onto the smear cotton 75, so that the smear cotton 75 is soaked with lubricating oil.

[0047] With the above scheme: when the metal plate is completely inserted into the inside of the feeding box 71, due to the gravity of the plate itself, it can slide down to the pouring plate 79 along the inside of the feeding box 71, at the same time, it can be separated from the between the wiping cotton 75, and it can slide down to the lower die 54 along with the pouring plate 79, so as to complete the feeding of the metal plate. The control system 2 drives the one-way valve 3 78 to recover, which can drive the pouring plate 79 to shrink below the feeding box 71, so as to avoid the pouring plate 79 from blocking the stamping mechanism 3.

[0048] As shown in Figure 1 , Figure 2 , Figure 5 and Figure 7 , it further includes four centering mechanisms 8, which are arranged around the four sides of the lower die 54 and are arranged on the machine base 1. The centering mechanism 8 includes an electric telescopic rod 3 81 installed on the machine base 1, and the output end of the electric telescopic rod 3 81 is connected with a push rod 82 close to the lower die 54.

[0049] With the above scheme: due to the operation of the electric telescopic rod 3 81, the push rod 82 can be driven to approach the lower die 54, and at the same time, it can be synchronized to the lower die 54.

[0051] With the above scheme: the control system 2 controls the electric telescopic rod 1 712 to drive the fixed block 713 and the double-headed piston 77 to reset and move. Due to the pushing movement of the double-headed piston 77, the one-way valve 3 78 can be pressed, so that the one-way valve 3 78 is opened, and the lubricating oil in the oil pipe 72 can flow into the oil supplement tank 76 through the double-headed piston 77, so as to realize the automatic oil supplement of the oil supplement tank 76 and the inside of the feeding box 71.

[0061] In use, the operator will need to insert the metal plate to be punched into the inside of the feed box 71, so that the upper and lower metal plate is in contact with the connecting pipe 45, when the plate is inserted, the plate will block the light source of the infrared sensor 710, at this time the infrared receiver 711 will not be able to receive infrared, at this time it will be determined that the plate is located between the wiping cotton 75, the control system 2 controls the electric telescopic rod 712 to start, drives the fixed block 713 and the double-headed piston 77 to move into the inside of the oil tank 76, then the oil body inside the feed box 71 and the circular hole 73 can be pressed, and the one-way valve 74 is opened, the oil body is pushed to the wiping cotton 75, so that the wiping cotton 75 is wetted with lubricating oil, at this time, as the operator pushes the plate, the surface of the plate can be uniformly contacted with the wiping cotton 75 and evenly coated with lubricating oil by the wiping cotton 75, when the metal plate is completely inserted into the inside of the feed box 71, due to the gravity of the plate itself, it can slide along the inside of the feed box 71 to the discharge plate 79, at the same time, it is separated from the wiping cotton 75 and slides down with the discharge plate 79 to the lower die 54, thereby completing the coating of the metal plate with lubricating oil and feeding, so that the lubricating oil can be evenly coated on the surface of the metal plate.

[0062] In the process of punching, the control system 2 drives the one-way valve 78 to recover, which can drive the discharge plate 79 to shrink below the feed box 71, at the same time, the electric telescopic rod 81 drives the push rod 82 to approach the lower die 54, and synchronously approaches the lower die 54, which can push the plate on the lower die 54 to the center, then the push rod 82 is retracted, and the plate is punched by the cooperation of the punching mechanism 3 and the lifting mechanism 5.

[0063] In the stamping process, the heat generated by the upper die 33 and the lower die 54 will be conducted to the heat conduction bar one 34 and the heat conduction bar four 56 through the heat conduction bar two 35 and the heat conduction bar three 55. Due to the downward stamping of the upper die 33, the cooling box one 61, the connecting pipe one 45, the connecting block 49 and the piston assembly 47 can be driven downward by the connecting frame 32. Due to the downward movement of the piston assembly 47, the spring 410 can be compressed. Due to the elastic recovery of the spring 410, the piston assembly 47 can be pushed downward and the oil below the piston assembly 47 in the oil supply barrel 41 can be extruded to enter the inside of the connecting pipe one 45 through the oil inlet nozzle 46, then enter the inside of the cooling box one 61 through the connecting pipe one 45, then enter the inside of the cooling box two 64 through the fixed pipe 62 and the sleeve pipe 63, and then contact with the heat conduction bar one 34 and the heat conduction bar four 56 to take away the heat on the heat conduction bar one 34 and the heat conduction bar four 56. The original lubricating oil in the cooling box one 61 and the cooling box two 64 is sent back to the inside of the middle oil storage barrel 42 through the connecting pipe two 65 and the movable pipe 66 again to form a circulation, which can achieve the effect of rapid cooling of the upper die 33 and the lower die 54, so that the oil in the cooling box one 61 and the cooling box two 64 can flow and be cooled by the lubricating oil, and the lubricating oil is heated to avoid solidification for a long time. When the piston assembly 47 descends, the inside of the oil storage barrel 42 can produce negative pressure and open the one-way air valve 44 to enter air for pressure compensation. When the oil carrying heat is pressed into the inside of the connecting pipe two 65 and the movable pipe 66 with larger diameter, the oil can be dispersed and elongated, so that the thickness of the oil in the connecting pipe two 65 and the movable pipe 66 is thin, and the temperature of the outside is conducted to the oil through the movable pipe 66 and the connecting pipe two 65 to cool the oil.

[0064] When the upper die 33 rises, the cooling box one 61 drives the connecting pipe one 45 and the piston assembly 47 to rise, and the one-way valve one 48 is affected by the positive pressure to open. When the piston assembly 47 rises, the oil above the piston assembly 47 can flow to the lower part of the piston assembly 47 in the oil supply barrel 41 through the piston assembly 47 to achieve the effect of oil supplement.

[0065] When the stamping is finished, the control system 2 controls the electric telescopic rod one 712 to drive the fixed block 713 and the double-headed piston 77 to reset and move. Due to the pushing movement of the double-headed piston 77, the one-way valve three 78 can be pressed to open, so that the lubricating oil in the oil pipe 72 can flow into the inside of the oil supplement barrel 76 through the double-headed piston 77 to achieve the automatic oil supplement of the inside of the oil supplement barrel 76 and the inside of the feeding box 71.
