Description

Technical Field

[0001] The utility model relates to the technical field of precision parts punching and cutting, in particular to a follow-up ejection type precision parts punching machine punching and cutting mechanism. Background Art

[0002] The metal parts processing technology mainly includes: cutting, bending, deep drawing, stamping and forging. Among them, stamping, also known as blanking, is a stamping process that uses a mold to separate the sheet material. After the mold completes the blanking of the sheet material, the movement of the material belt is used to achieve the purpose of automatic loading. For blanking that does not require shaping, there is no need to consider the unloading after the blanking is completed. The workpiece will automatically leak downward through the material hole. However, for shaping blanking, it is necessary to remove the product from the lower die after the product is formed. However, due to the setting of the blanking mechanism and the obstruction of the material belt, it is not convenient to separate the formed product from the lower die, which greatly affects the overall blanking efficiency.

[0030] Embodiment 1: This embodiment discloses: a base 1, a hydraulic rod 2 is fixedly installed on the upper end of the base 1, and an upper die 3 is fixedly connected to the lower end of the hydraulic rod 2, and a clearance hole 4 is opened on the lower surface of the upper die 3, a lower die 5 is fixedly arranged on the lower end of the base 1, and a positioning column 6 is fixedly arranged on the upper surface of the lower die 5, and a follow-up mechanism is arranged inside the base 1, and the automatic ejection of the punched and cut molding material is realized through the displacement of the upper die 3;

[0031] The follow-up mechanism includes: a sliding column 7, which is slidably mounted on the lower surface of the lower mold 5, and a stripping module 8 is fixedly arranged on the upper end of the sliding column 7, a sliding sliding plate 9 is mounted on the outer surface of the lower end of the base 1, and an extrusion groove 10 is opened on the upper surface of the sliding plate 9, a rotating guide wheel 11 is mounted on the inner surface of the middle section of the base 1, a sliding unlocking block 12 is mounted on the inner surface of the upper end of the base 1, and a guide rope 13 is connected between the lower surface of the unlocking block 12 and the side surface of the sliding plate 9, and a contact rod 14 is fixedly arranged on the outer surface of the unlocking block 12 facing the upper mold 3;

[0032] A spring is connected between the sliding column 7 and the lower die 5, a spring is connected between the sliding plate 9 and the base 1, the longitudinal section of the extrusion groove 10 is a right-angle trapezoid, and the inclined surface of the extrusion groove 10 is arranged toward the lower end of the sliding column 7;

[0033] The guide rope 13 passes through the two guide wheels 11 from both sides, a spring is connected between the unlocking block 12 and the base 1, and one end of the contact rod 14 is located between the upper surface of the upper mold 3 and the inner top surface of the upper end of the base 1;

[0034] During punching, the hydraulic rod 2 installed on the upper end of the base 1 starts to drive the upper die 3 to slide down and punch the sheet through the cooperation with the cavity of the lower die 5. At this time, the sheet is separated from the material strip until the upper die 3 and the lower die 5 are accurately molded through the cooperation of the makeshift hole 4 and the positioning column 6, and the sheet is formed through the cavity of the upper die 3 and the lower die 5. Then the hydraulic rod 2 installed on the upper end of the base 1 starts to drive the upper die 3 to slide up. During the upward movement, the upper die 3 drives the unlocking block 12 to slide up by squeezing the contact rod 14. The unlocking block 12 pulls the sliding plate 9 through the guide rope 13 under the action of the guide wheel 11. The sliding plate 9 slides through the inclined surface of the extrusion groove 10 to squeeze the lower end of the sliding column 7, so that the sliding column 7 drives the stripping module 8 to slide up and eject the product out of the lower die 5.

[0038] When punching is required, the operator pushes the locking rods 16 on both sides to slide with both hands at the same time, so that the locking rods 16 on both sides can slide out of the sliding range of the limit block 15, and then the operator steps on the starting switch to start the hydraulic rod 2, thereby preventing the locking rod 16 from blocking the limit block 15 from sliding down when the hydraulic rod 2 is started. When the upper mold 3 slides up, the limit block 15 squeezes the inclined surface of the locking rod 16, so that the locking rod 16 slides horizontally to pass the limit block 15, so that the upper mold 3 can slide back to its original position.
