A variety of stamping devices are currently available on the market, with common designs consisting of a base, bracket, hydraulic cylinder, and upper and lower dies. These devices, driven by a hydraulic cylinder, enable the upper die base to drive the punch, which then presses the workpiece placed on the lower die.
[0003] However, the bending heads of traditional stamping devices are mostly fixed in design. When stamping and bending workpieces of different shapes and sizes, different stamping heads need to be replaced, which limits their scope of application and processing efficiency and increases maintenance difficulty and cost.

[0018] The following is combined with Figure 1-3 This application is described in further detail.
[0019] The embodiment of the present application discloses a punching device for machining electromechanical parts. Figure 1-3A stamping device for processing electromechanical parts includes a base 1, a bracket 2 is installed on the base 1, a hydraulic cylinder 3 is installed on the bracket 2, an upper die base 5 is installed on the movable end of the hydraulic cylinder 3, and the upper die base 5 includes a tool holder 501 installed on the movable end of the hydraulic cylinder 3, guide sleeves 502 are welded on both sides of the tool holder 501, and a combined punch 6 is installed on the tool holder 501. By controlling the extension and contraction of the hydraulic cylinder 3, the tool holder 501 and the guide sleeve 502 are driven to move along the Z axis, thereby driving the combined punch 6 to complete the stamping operation.
[0020] Reference Figure 3 The combined punch 6 includes a fixed cutter head 601 detachably mounted on the cutter holder 501. For example, the fixed cutter head 601 is provided with a plurality of bolt holes, and bolts 7 are installed inside the bolt holes. The ends of the bolts 7 pass through the cutter holder 501 and are connected with nuts. A plurality of adjustable punches 602 are installed on the outside of the fixed cutter head 601 on the cutter holder 501. The adjustable punches 602 include an adjustable cutter head 6021 slidably mounted inside the cutter holder 501. A suspension rod 6022 is installed on the upper end of the adjustable cutter head 6021. The suspension rod 6022 is connected to the cutter holder 501 in a detachable suspension manner. For example, a through hole is provided on the top of the cutter holder 501. The suspension rod 6022 includes a connecting rod installed in the through hole. One end of the connecting rod is connected to the adjustable cutter head 6021, and the other end is threadedly connected with a nut.
[0021] Reference Figure 3 A positioning hole 8 is provided on the adjustable cutter head 6021, and a positioning unit 603 is installed on the positioning hole 8. The positioning unit 603 can select a quick-release pin of appropriate size and model as needed. A plurality of mounting holes 9 are provided on the tool holder 501. The quick-release pin passes through the positioning hole 8 and the mounting hole 9 to fix the position of the adjustable cutter head 6021 and the fixed cutter head 601.
[0022] Reference Figure 2 A lower die 4 is also installed on the base 1. The lower die 4 includes a mounting plate 401 mounted on the base 1 by bolts. A forming groove 402 is installed on the mounting plate 401. The forming groove 402 cooperates with the combined punch 6 to stamp and bend the workpiece to achieve folding of the workpiece. Two guide rods 403 are also installed on the mounting plate 401. The two guide rods 403 are slidably installed in the corresponding guide sleeves 502. The guide sleeves 502 are guided by the guide rods 403 to prevent the combined punch 6 from moving downward and deflecting.
[0023] The implementation principle of a punching device for machining electromechanical parts in the embodiment of the present application is as follows:
[0024] Adjust the adjustable punch 602 according to the shape and size of the workpiece, remove the corresponding quick-release pin, and release the position lock of the adjustable punch 602 by the quick-release pin, so that it can move up and down when subjected to force without bending the workpiece.
[0025] The stamping device's control system is activated, controlling the expansion and contraction of hydraulic cylinder 3 to drive upper die holder 5 along the Z-axis. This drives tool holder 501 and combination punch 6 downward, while guide sleeve 502 slides along guide rod 403 to ensure stability and precision during the stamping process. When combination punch 6 contacts the workpiece, fixed tool head 601 and adjustable punch 602 work together to stamp and bend the workpiece.
[0026] After the stamping is completed, the hydraulic cylinder 3 is retracted in the opposite direction, driving the upper die base 5 and the combined punch 6 to rise back to the initial position. Take out the processed workpiece and check whether the quality and size of the stamping and bending meet the requirements.
[0027] Finally, a few points should be explained: First, in the description of this application, it should be noted that, unless otherwise specified or limited, the terms "mounted," "connected," and "connected" should be understood in a broad sense, and may refer to mechanical or electrical connections, internal communication between two components, or direct connection. "Up," "down," "left," and "right" are only used to indicate relative positional relationships. When the absolute positions of the objects being described change, the relative positional relationships may also change.
