Description

Technical Field

[0001] This utility model relates to the field of molds, specifically to a punching mechanism for stamping molds. Background Technology

[0002] Stamping dies are special process equipment used in cold stamping to process materials (metal or non-metal) into parts (or semi-finished products). They are called cold stamping dies (commonly known as cold stamping dies). Stamping is a pressure processing method that uses dies mounted on a press to apply pressure to materials at room temperature, causing them to separate or plastically deform, thereby obtaining the desired parts.

[0003] Copper busbars generally refer to copper busbars. Copper busbars are indispensable conductive materials for manufacturing motor windings, high and low voltage electrical appliances, switch contacts, and conductors for power supply and distribution installations.

[0004] The existing copper busbar drilling molds have the following shortcomings:

[0005] The required hole diameter varies depending on the thickness and width of the copper busbar. However, existing copper busbar drilling dies typically only install one type of punch at a time. When a different hole diameter is needed, the previous punch must be removed and replaced with a new one, reducing drilling efficiency.

[0006] Existing copper busbar molds require punch replacements, making it impossible to quickly produce copper busbars of different hole sizes, resulting in poor practicality and flexibility. Utility Model Content

[0007] The purpose of this utility model is to provide a punching mechanism for stamping dies.

[0008] To achieve this objective, the present invention adopts the following technical solution:

[0009] A punching mechanism for a stamping die is provided, comprising a base, wherein the base is horizontally arranged;

[0010] It also includes controllers, molds, drive components, and opening components;

[0011] The controller is fixed to the top of the base by a support rod;

[0012] The mold is located on the top of the base. The mold includes an upper mold and a lower mold. A fixed plate is vertically installed on the top of the base. Two guide rails are symmetrically arranged on the outer wall of the fixed plate. The upper mold is slidably positioned between the two guide rails by two sliders. The lower mold is fixedly installed on the top of the base.

[0013] The drive assembly is located on the outer wall of the upper mold, and the opening assembly is located on the inner wall of the upper mold. The drive assembly and the controller are electrically connected.

[0014] Preferably, the opening assembly includes a rotating rod, a plurality of first punches and a plurality of second punches. The rotating rod is rotatably mounted on the inner wall of the upper die via two rotating shafts. The plurality of first punches and the plurality of second punches are symmetrically arranged on the outer wall of the rotating rod in the circumferential direction, and the diameter of each first punch is smaller than the diameter of one second punch.

[0015] Preferably, the drive assembly includes a stepper motor, a first gear, and a second gear. The stepper motor is fixed on the outer wall of the upper mold, the first gear is fixed on its output end, and the second gear is fixed on the outer wall of one of the rotating shafts. The first gear and the second gear are meshed together, and the stepper motor is electrically connected to the controller.

[0016] Preferably, a cylinder is fixedly installed on the top of the base, and a push plate is fixedly installed between the output end of the cylinder and the outer wall of the upper mold. The cylinder is electrically connected to the controller.

[0017] Preferably, the top of the lower mold is provided with a material groove, and a material outlet is provided through the side of the material groove.

[0021] This utility model designs an opening assembly, namely a rotating rod, several first punches, and several second punches. The first punches and the second punches are arranged symmetrically, and their positions can be quickly changed by the rotating rod to punch copper busbars with different hole diameters, thereby meeting the opening requirements of copper busbars of different specifications and improving the practicality and flexibility of the mechanism.

[0022] This invention, through the design of a drive component, namely a stepper motor, a first gear, and a second gear, enables the rapid interchange of several first punches and several second punches, thereby punching holes of different diameters into copper busbars without the need for frequent disassembly and assembly of punches, thus improving drilling efficiency.

[0023] This utility model features a material inlet that is connected to the material trough. After the copper busbar is drilled, workers can easily and quickly remove the copper busbar from the trough by reaching into the material inlet.

Detailed Implementation

[0032] The technical solution of the present invention will be further described below with reference to the accompanying drawings and specific embodiments.

[0033] The accompanying drawings are for illustrative purposes only and are schematic diagrams, not actual images. They should not be construed as limiting the scope of this patent. To better illustrate the embodiments of the present invention, some parts in the drawings may be omitted, enlarged, or reduced, and do not represent the actual dimensions of the product.

[0034] Reference Figures 1 to 6 As shown, a punching mechanism for a stamping die includes a base 1, which is horizontally positioned.

[0035] It also includes controller 2, mold, drive assembly and opening assembly;

[0036] The controller 2 is fixedly mounted on the top of the base 1 by a support rod;

[0037] The mold is located on the top of the base 1. The mold includes an upper mold 3 and a lower mold 4. A fixed plate 5 is vertically provided on the top of the base 1. Two guide rails 6 are symmetrically arranged on the outer wall of the fixed plate 5. The upper mold 3 is slidably located between the two guide rails 6 by two sliders 7. The lower mold 4 is fixedly located on the top of the base 1.

[0038] The drive assembly is located on the outer wall of the upper mold 3, and the opening assembly is located on the inner wall of the upper mold 3. The drive assembly and the controller 2 are electrically connected.

[0039] Reference Figures 1 to 6 As shown, the punching assembly includes a rotating rod 8, several first punches 9, and several second punches 10. The rotating rod 8 is rotatably mounted on the inner wall of the upper die 3 via two rotating shafts 11. The several first punches 9 and several second punches 10 are symmetrically arranged on the outer wall of the rotating rod 8 in the circumferential direction, and the diameter of each first punch 9 is smaller than the diameter of one second punch 10. The axial directions of each first punch 9 and each second punch 10 are consistent, thereby ensuring that the hole spacing punched on the copper busbar is the same regardless of whether it is punched by several first punches 9 or several second punches 10, which is beneficial to improving the punching quality. In addition, each first punch 9 and each second punch 10 is threadedly connected to the rotating rod 8, so that when a certain first punch 9 or second punch 10 is damaged, it is convenient to replace it quickly without discarding the entire punching mechanism, which helps to reduce the cost of use.

[0040] Reference Figures 1 to 6 As shown, the drive assembly includes a stepper motor 12, a first gear 13, and a second gear 14. The stepper motor 12 is fixedly mounted on the outer wall of the upper mold 3, the first gear 13 is fixedly mounted on its output end, and the second gear 14 is fixedly mounted on the outer wall of one of the rotating shafts 11. The first gear 13 and the second gear 14 are meshed together. The stepper motor 12 is electrically connected to the controller 2. Due to the different specifications of the copper busbars, i.e., their thickness and width vary, holes of different diameters need to be drilled. When encountering a copper busbar with a smaller thickness and width, the controller 2 starts the stepper motor, thereby driving the first gear 13 through its output end. When gear 13 rotates clockwise, the first gear 13 and the second gear 14 mesh together, and the diameter of the first gear 13 is smaller than the diameter of the second gear 14. The rotating rod 8 is rotatably connected to the upper mold 3 through two rotating shafts 11, and the second gear 14 is fixedly connected to one of the rotating shafts 11. This causes the rotating rod 8 to rotate 180 degrees counterclockwise, which in turn drives the positions of several first punches 9 and several second punches 10 to be interchanged, making it easier to punch several smaller holes. This allows the mechanism to punch holes of different diameters, thereby meeting different punching requirements and improving the flexibility and practicality of the mechanism.

[0041] Reference Figures 1 to 6As shown, a cylinder 15 is fixedly installed on the top of the base 1. A push plate 16 is fixed between the output end of the cylinder 15 and the outer wall of the upper mold 3. The cylinder 15 is electrically connected to the controller 2. When copper is discharged into the material trough 17, the controller 2 starts the cylinder 15, thereby causing its output end to retract. Since its output end is fixedly connected to the upper mold 3 through the push plate 16, the upper mold 3 and the fixed plate 5 are slidably connected through two guide rails 6 and two sliders 7. Then, the push plate 16 drives the upper mold 3 to descend vertically, that is, drives the upper mold 3 to move closer to the lower mold 4 until the upper mold 3 and the lower mold 4 are tightly closed.

[0042] Reference Figures 1 to 6 As shown, the top of the lower mold 4 is provided with a material groove 17, and a material outlet 18 is provided through the side of the material groove 17. When the copper busbar is punched, the copper busbar is first placed horizontally into the inside of the material groove 17. Preferably, the material groove 17 is designed to be the same size as the copper busbar. After the copper busbar is punched, the stamped copper busbar is taken out through the material outlet 18. The material outlet 18 makes it easy for a person to reach into the material groove 17 to pull up the copper busbar, thereby improving the material feeding efficiency.

[0043] Reference Figures 1 to 6 As shown, four guide rods 19 are fixedly provided at the four corners of the bottom of the upper mold 3, and four insertion holes 20 are provided at the four corners of the top of the lower mold 4. Each guide rod 19 is inserted into one insertion hole 20. During the process of the upper mold 3 approaching the lower mold 4, the four guide rods 19 are vertically inserted into the four insertion holes 20. The two are inserted and cooperated to play a guiding and limiting role, improve the accuracy of the docking between the upper mold 3 and the lower mold 4, thereby improving the stamping effect and thus improving the punching effect.

[0044] Reference Figures 1 to 6 As shown, the inner wall of the upper mold 3 is provided with a relief groove 21 for a plurality of first punches 9 and a plurality of second punches 10 to rotate. The relief groove 21 provides relief space when the plurality of first punches 9 and the plurality of second punches 10 rotate, preventing them from colliding with the upper mold 3 during rotation and damaging the mold, thus playing a protective role.
