Description

Technical Field

[0001] The utility model relates to the technical field related to metal stamping, in particular to a metal stamping die with a flipping function. Background Art

[0002] In daily processing of hardware, the most important thing is to use stamping dies to realize the processing of the shape of hardware items. This working method refers to a pressure processing method in which a mold installed on a press is used to apply pressure to the material at room temperature to cause separation or plastic deformation, thereby obtaining the required parts. However, existing hardware stamping dies are generally fixed and cannot be flipped. Therefore, after the hardware is stamped and formed, it needs to be manually removed, which is time-consuming and labor-intensive, and there are safety hazards. The patent document with application number CN202223392414.2 in my country discloses a metal stamping die with a flipping function, including a frame and a flipping unit; the frame: a U-shaped frame is provided at the front end of its upper surface, the upper end of the inner cavity of the U-shaped frame is rotatably connected to the lower die through a rotating shaft, a support plate is provided at the rear end of the upper surface of the frame, the rear end of the lower surface of the lower die contacts the upper surface of the support plate, symmetrically distributed guide rods are provided at the four corners of the upper surface of the lower die, an upper die is slidably connected between the four guide rods, and a connecting flange is provided in the middle of the upper surface of the upper die; the flipping unit is arranged on the lower surface of the frame, and the flipping unit is fixedly connected to the outer ends of the rotating shaft corresponding to the left and right ends of the lower die respectively; the device can flip the die, but the flipping angle is limited.

DETAILED DESCRIPTION

[0018] The technical solutions in the embodiments of the present invention will be described clearly and completely 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 of the embodiments.

[0019] Reference Figure 1-3 A metal stamping die with a flipping function is shown, comprising:

[0020] The upper die 1 and the lower die 2 are controlled to move up and down by the existing stamping device. In order to realize the flipping and discharging operation of the lower die 2, a receiving frame 3 is correspondingly arranged on the lower side of the lower die 2. The receiving frame 3 is arranged in a U-shape. Two arc-shaped limit plates 4 are symmetrically fixed on the upper end of the receiving frame 3. The two sides of the lower die 2 are processed to match the shape of the arc-shaped limit plates 4 and the two arc-shaped limit plates 4 are respectively attached to the two sides of the lower die 2 to assist in limiting the position of the lower die 2 without affecting the flipping action of the lower die 2. The front and rear sides of the lower die 2 are coaxially fixed with a rotating shaft 5. Two supporting rods 6 are symmetrically arranged on the front and rear sides of the receiving frame 3. Limit receiving parts corresponding to the rotating shaft 5 are arranged on the upper sides of the two supporting rods 6 to receive the lower die 2, and the lower die 2 can rotate at the same time. In addition, a control component for driving the lower die 2 to flip is arranged on the receiving frame 3, and a support and limiting component for limiting and fixing the lower die 2 is also arranged on the receiving frame 3, which fully guarantees the flippability and limitable stamping functions of the lower die 2.

[0021] In order to realize the support of the lower mold 2 and realize the detachability of the lower mold 2, specifically, the limiting support member includes an arc groove arranged on the support rod 6, and an arc hoop 7 is arranged on the upper side of the support rod 6 corresponding to the arc groove. Both ends of the arc hoop 7 are arranged to be bent and fixedly connected to the support rod 6 by bolts 8.

[0022] In order to realize the flipping of the lower mold 2 and cooperate with the detachable structure of the lower mold 2, specifically, the control component includes an extension frame 9 fixedly arranged on one of the support rods 6, a circular opening is arranged on the extension frame 9, and a driven sprocket 10 corresponding to the position of the circular opening is rotatably arranged on the extension frame 9, a rectangular opening is coaxially arranged in the driven sprocket 10, and a driving short rod 11 is matched in the rectangular opening, and the driving short rod 11 is coaxially fixedly connected to one of the rotating shafts 5, a servo motor 12 is fixedly arranged on the extension frame 9, and a driving sprocket 13 is coaxially fixedly connected to the output end of the servo motor 12, and the driving sprocket 13 is connected to the driven sprocket 10 through a chain. The servo motor 12 can drive the driving sprocket 13 to rotate, and the driving sprocket 13 drives the driven sprocket 10 to rotate through the chain, thereby driving the driving short rod 11 to rotate, and then driving the lower mold 2 to rotate through the rotating shaft 5 to perform a flipping operation.

[0023] The two ends of the two support plates 14 are rotatably connected to the two arc-shaped limit plates 4, and the other ends of the two support plates 14 are rotatably connected to the support frame 3. When the support plates 14 and the arc-shaped limit plates 4 are limited to each other, they are in a horizontal state. When the lower mold 2 needs to be flipped, the two hydraulic telescopic rods 15 are controlled to shorten, the inclination angles of the two support plates 14 are changed, and the restriction of the two support plates 14 on the lower mold 2 is released. When the lower mold 2 needs to be rotated and reset, one of the support plates 14 can be reset to a horizontal state to receive the lower mold 2. After the reception is completed, the other support plate 14 is reset to achieve stable limiting. Because the structure of the hydraulic telescopic rod 15 can play a certain buffering role after being impacted, it can avoid rigid contact.

[0024] In some embodiments, in order to facilitate the discharge of waste generated by stamping and facilitate operation when the workpiece is discharged at an angle, an open opening is provided on the lower side of the receiving frame 3 for the receiving and conveying structure to be installed and entered.

[0025] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes within the technical scope disclosed by the present invention according to the technical scheme and the utility model concept of the present invention, which should be covered by the protection scope of the present invention.
