Figure 3 It is the left view of the stamping die in the clamped state. Figure 4 yes Figure 3 Schematic diagram of part of the structure. Figure 5 It is the main view of the stamping die in the open state. Figure 6 yes Figure 5 Schematic diagram of part of the structure. Figure 7 It is the left view of the stamping die in the open state. Figure 8 yes Figure 7 Schematic diagram of part of the structure. Among them, Figures 1 to 8 Both up and down directions are height directions. Figure 1 、 Figure 2 、 Figure 5 and Figure 6 The left and right directions are both the second horizontal directions. Figure 3 、 Figure 4 、 Figure 7 and Figure 8 The left and right directions are both the first horizontal directions.

[0055] like Figures 1 to 8As shown, the utility model provides a stamping die, which includes a forming punch 1, a mounting seat 2 and a forming module 3. The forming punch 1 can be raised and lowered in the height direction. The mounting seat 2 and the forming module 3 are both located below the forming punch 1. The forming module 3 includes a module body 31, which is slidably arranged on the mounting seat 2 along the first horizontal direction and has a first working position and a second working position. The forming punch 1 is provided with a forming groove 11 on the first side along the second horizontal direction. The forming groove 11 is located at the bottom of the forming punch 1 along the height direction and passes through the bottom end face of the forming punch 1. The first horizontal direction is perpendicular to the second horizontal direction and is perpendicular to the height direction. The module body 31 is provided with a forming protrusion 311 on the second side along the second horizontal direction, and is recessed with a receiving groove 312. The forming protrusion 311 and the receiving groove 312 are adjacently distributed in the height direction, and the receiving groove 312 is used to receive the strip 100. When the module body 31 is in the first working position, the forming protrusion 311 is opposite to the forming groove 11 in the height direction, so that the forming protrusion 311 can be plugged into the forming groove 11. When the module body 31 is in the second working position, the forming protrusion 311 is spaced apart from the forming punch 1 along the first horizontal direction.

[0056] To bend the strip 100 two or more times in the same clockwise direction, adjust the module body 31 in the first horizontal direction to the first working position so that the forming protrusion 311 is aligned with the forming groove 11 in the height direction. Place the strip 100 on top of the forming protrusion 311, supporting it. Adjust the position of the strip 100 in the first and / or second horizontal directions so that the first area of ​​the strip 100 to be bent is aligned with the forming groove 11. Move the forming punch 1 in the height direction toward the forming protrusion 311. Once the forming punch 1 contacts the strip 100, continue moving the forming punch 1 in the height direction toward the forming protrusion 311, applying downward pressure to the strip 100, until the first area of ​​the strip 100 to be bent is bent.

[0057] Move the forming punch 1 in the height direction away from the forming groove 11, and adjust the second area of ​​the strip 100 to be bent in the second horizontal direction so that it is aligned with the forming groove 11. At this point, the already bent area of ​​the strip 100 is accommodated in the accommodating groove 312. Move the forming punch 1 in the height direction closer to the forming protrusion 311. After the forming punch 1 contacts the strip 100, continue to move the forming punch 1 in the height direction closer to the forming protrusion 311 to apply downward pressure to the strip 100 until the second area of ​​the strip 100 to be bent is bent. This process is repeated repeatedly, so that the strip 100 can be bent multiple times in the same clockwise direction.

[0058] Therefore, the stamping die can be used to bend the strip 100 into a part having one bend, or to bend the strip 100 into a part having at least two bends in the same clockwise direction, thereby effectively improving the versatility of the stamping die and simplifying operation.

[0059] Among them, Figures 1 to 8 As shown, the forming module 3 also includes a translation drive member 32 and a first elastic member 33. One end of the first elastic member 33 is fixedly connected to or abuts the module body 31, and the other end is fixedly connected to or abuts the mounting base 2. The translation drive member 32 can drive the module body 31 to move to the first working position along the first horizontal direction. The elastic restoring force of the first elastic member 33 can drive the module body 31 to move to the second working position along the first horizontal direction. This allows the forming protrusion 311 to face the forming groove 11 in the height direction, so that the forming protrusion 311 can be plugged into the forming groove 11; and the forming protrusion 311 can be spaced apart from the forming punch 1 along the first horizontal direction.

[0060] Preferably, the module body 31 and / or the mounting base 2 are provided with a limiting mounting groove 313, and the first elastic member 33 is positioned within the limiting mounting groove 313. Specifically, when the module body 31 is provided with the limiting mounting groove 313, one end of the first elastic member 33 is fixedly connected to or abuts the inner wall of the limiting mounting groove 313, and the other end is fixedly connected to or abuts the mounting base 2. When the mounting base 2 is provided with the limiting mounting groove 313, one end of the first elastic member 33 is fixedly connected to or abuts the inner wall of the limiting mounting groove 313, and the other end is fixedly connected to or abuts the module body 31. When both the module body 31 and the mounting base 2 are provided with limiting mounting grooves 313, the two ends of the first elastic member 33 are provided in a one-to-one correspondence with the two limiting mounting grooves 313, and the end of the first elastic member 33 is fixedly connected to or abuts the inner wall of the limiting mounting groove 313. This arrangement can limit the location of the first elastic member 33 and enable the module body 31 to smoothly move back and forth between the first working position and the second working position along the first horizontal direction. In this embodiment, if Figure 4 and Figure 8 As shown, the module body 31 is provided with a limiting installation groove 313 as an example.

[0061] Specifically, the translation drive member 32 is a mechanical push rod, an electric push rod or a cylinder, etc. It can drive the module body 31 to move to the first working position along the first horizontal direction. Figure 2 、 Figure 3 、 Figure 7 and Figure 8As shown, the translation drive member 32 is preferably a mechanical push rod. A first inclined surface is provided at a first end of the module body 31 along the first horizontal direction. The mechanical push rod is provided with a second inclined surface 321. The first inclined surface can be in surface contact with the second inclined surface 321. When the first inclined surface and the second inclined surface 321 are in surface contact, a force is applied to the first inclined surface by the second inclined surface 321, thereby driving the module body 31 to move from the second working position to the first working position along the first horizontal direction, while avoiding energy consumption.

[0062] Specifically, if Figure 1 、 Figure 3 、 Figure 5 and Figure 7 As shown, the stamping die also includes a pressure drive mechanism and an upper die assembly 4. One end of the forming punch 1 is fixedly connected to the interior of the upper die assembly 4 along the height direction, while the other end extends out of the upper die assembly 4. The pressure drive mechanism can drive the upper die assembly 4 to rise and fall along the height direction, thereby driving the forming punch 1 to rise and fall along the height direction. The specific structure of the pressure drive mechanism is known in the art and will not be repeated here.

[0063] Alternatively, as Figure 1 、 Figure 3 、 Figure 5 and Figure 7 As shown, the stamping die also includes a stripper plate assembly 5 and a second elastic member 61. The stripper plate assembly 5 is slidably connected to the upper die base assembly 4 along the height direction, and is close to the module body 31 relative to the upper die base assembly 4. One end of the second elastic member 61 is fixedly connected or abuts the upper die base assembly 4, and the other end is fixedly connected or abuts the stripper plate assembly 5. Under the action of external force, the stripper plate assembly 5 can move along the height direction so that the forming punch 1 partially extends out of the stripper plate assembly 5. The elastic restoring force of the second elastic member 61 can drive the stripper plate assembly 5 to move along the height direction so that the forming punch 1 is retracted into the stripper plate assembly 5. It can be understood that when the stripper plate assembly 5 is not subject to external force, it is spaced apart from the upper die base assembly 4 along the height direction.

[0064] When the forming punch 1 punches the strip 100, the pressure drive mechanism drives the upper die base assembly 4 to move downward in the height direction close to the module body 31, and drives the stripper plate assembly 5 to move downward in the height direction close to the module body 31 at the same time. After the stripper plate assembly 5 descends to a certain position in the height direction, the stripper plate assembly 5 moves upward in the height direction under the action of an external force, so that the forming punch 1 partially extends out of the stripper plate assembly 5 to punch the strip 100. During this process, the second elastic member 61 is compressed.

[0065] When the forming punch 1 completes the stamping of the strip 100, the pressure drive mechanism drives the upper die base assembly 4 and the stripper plate assembly 5 to move upward in the height direction away from the module body 31 simultaneously. During this process, the elastic restoring force of the second elastic member 61 is applied to the stripper plate assembly 5 and drives the stripper plate assembly 5 to move downward in the height direction and be spaced apart from the upper die base assembly 4, so that the strip 100 and the forming punch 1 can be separated, preventing the strip 100 from moving away from the module body 31 or the strip 100 from falling along with the forming punch 1, etc., thereby facilitating the disassembly of the processed strip 100; secondly, the elastic restoring force of the second elastic member 61 is applied to the stripper plate assembly 5 and drives the stripper plate assembly 5 to move downward in the height direction and be spaced apart from the upper die base assembly 4, so that the forming punch 1 is located in the stripper plate assembly 5, which can protect the forming punch 1.

[0066] Specifically, if Figure 1 and Figure 5 As shown, the upper die base assembly 4 is provided with a first mounting hole extending vertically, the first mounting hole comprising a first through hole and a first threaded hole in communication; a first screw plug 62 is threadedly connected to the first threaded hole; a second elastic member 61 is positioned in the first through hole, one end of the second elastic member 61 abutting against the first screw plug 62, and the other end abutting against the stripper plate assembly 5. The elastic restoring force of the second elastic member 61 can drive the stripper plate assembly 5 to move vertically, allowing the forming punch 1 to be retracted into the stripper plate assembly 5 along the vertical direction.

[0067] Alternatively, as Figure 1 、 Figure 3 、 Figure 5 and Figure 7 As shown, the stamping die also includes a lower die base assembly 7 and a third elastic member 81, and the mounting seat 2 is slidably arranged on the lower die base assembly 7 along the height direction. One end of the third elastic member 81 is fixedly connected or abutted with the mounting seat 2, and the other end is fixedly connected or abutted with the lower die base assembly 7. The mounting seat 2 can abut on the limiting surface 721 of the lower die base assembly 7 along the height direction; when the mounting seat 2 abuts against the limiting surface 721, the upper die base assembly 4 and the lower die base assembly 7 are both pressed against the stripper plate assembly 5, the horizontal receiving surface 3111 of the forming protrusion 311 is flush with the top end surface of the lower die base assembly 7, the forming punch 1 partially extends out of the stripper plate assembly 5, and the horizontal receiving surface 3111 is used to hold the strip 100; the elastic restoring force of the third elastic member 81 can drive the mounting seat 2 away from the limiting surface 721 along the height direction, so that the forming protrusion 311 at least partially extends out of the lower die base assembly 7.

[0068] The pressure drive mechanism drives the upper die base assembly 4 to rise and fall in the height direction, thereby driving the stripper plate assembly 5 to rise and fall in the height direction synchronously; after the stripper plate assembly 5 begins to abut the lower die base assembly 7, the stripper plate assembly 5 applies a reaction force to the second elastic member 61 to drive the second elastic member 61 to elastically deform until the upper die base assembly 4 and the lower die base assembly 7 are both pressed against the stripper plate assembly 5. This arrangement allows the stripper plate assembly 5 and the lower die base assembly 7 to clamp the strip 100 when the mounting base 2 is supported on the limit surface 721, and the forming punch 1 can effectively apply downward pressure to the strip 100 to bend the desired bending area on the strip 100. Secondly, the horizontal receiving surface 3111 of the forming protrusion 311 is flush with the top end surface of the lower die base assembly 7, so that the length of the strip 100 is not limited, that is, a strip 100 of any length can be bent, which can further improve the working performance of the stamping die. It can be understood that the pressure driving mechanism drives the stripper plate assembly 5 along the height direction to apply a force to the mounting seat 2.

[0069] In this embodiment, if Figure 1 、 Figure 3 、 Figure 5 and Figure 7 As shown, the end of the mechanical push rod that is not provided with the second inclined surface 321 is preferably fixedly connected to the stripper plate assembly 5. Preferably, along the height direction, the end portion of the mechanical push rod provided with the second inclined surface 321 extends out of the stripper plate assembly 5. When the stripper plate assembly 5 abuts against the lower die base assembly 7, the second inclined surface 321 pushes the first inclined surface so that the module body 31 is located in the first working position. It can be understood that at this time, the relative position of the stripper plate assembly 5 and the upper die base assembly 4 has not changed, and the stripper plate assembly 5 is not abutting against the upper die base assembly 4.

[0070] After the module body 31 moves to the first working position, it continues to drive the stripper plate assembly 5 along the height direction to approach the mounting seat 2. The stripper plate assembly 5 applies a reaction force to the second elastic member 61 to drive the second elastic member 61 to undergo elastic deformation until the upper die base assembly 4 and the lower die base assembly 7 are both pressed against the stripper plate assembly 5. The stripper plate assembly 5 and the lower die base assembly 7 clamp the strip 100, and the forming punch 1 applies downward pressure to the strip 100 to bend the area on the strip 100 where the desired bending is desired.

[0071] This arrangement enables smooth and continuous progress: pushing the module body 31 along the first horizontal direction to the first working position, and bending the desired bending area on the strip 100 by the forming punch 1. This improves the working performance and efficiency of the stamping die.

[0072] Specifically, in this embodiment, Figure 1 and Figure 3As shown, when the mounting base 2 is supported on the limiting surface 721, and the upper die assembly 4 and the lower die assembly 7 are both pressed against the stripper plate assembly 5, the stamping die is in a clamped state. Figure 5 and Figure 7 As shown, when the stripper plate assembly 5 is away from the mounting base 2 and the lower die base assembly 7, the stamping die is in an open die state.

[0073] In other embodiments, the translation drive member 32 may also be disposed on the upper die base assembly 4 or the lower die base assembly 7 , so as to drive the module body 31 to move from the second working position to the first working position along the first horizontal direction.

[0074] Specifically, if Figure 1 、 Figure 3 、 Figure 5 and Figure 7 As shown, the lower die assembly 7 is provided with a second mounting hole extending vertically from bottom to top. The second mounting hole comprises a second through-hole and a second threaded hole that are interconnected. The second threaded hole is further away from the mounting base 2 than the second through-hole. A second screw plug 82 is threadedly connected to the second threaded hole. A third elastic member 81 is positioned in the second through-hole, with one end of the third elastic member 81 abutting against the second screw plug 82 and the other end abutting against the mounting base 2. The elastic restoring force of the third elastic member 81 can drive the mounting base 2 vertically away from the limiting surface 721, allowing the molding protrusion 311 to at least partially protrude from the lower die assembly 7.

[0075] Optionally, one of the stripper plate assembly 5 and the lower die base assembly 7 is provided with a positioning groove, and the other is provided with a positioning protrusion. When the stripper plate assembly 5 abuts the lower die base assembly 7 in the height direction, the positioning groove and the positioning protrusion engage with each other. This limits the stripper plate assembly 5 to movement relative to the lower die base assembly 7 only in the height direction, thereby ensuring the quality of the bent parts.

[0076] Among them, Figure 6 As shown, the forming groove 11 includes a first stamping surface 111 and a second stamping surface 112 connected to each other; the forming protrusion 311 includes a horizontal receiving surface 3111 and a forming surface 3112 connected to each other. The horizontal receiving surface 3111 is used to receive the strip 100. The first stamping surface 111 corresponds to the horizontal receiving surface 3111. The second stamping surface 112 corresponds to the forming surface 3112.

[0077] Alternatively, as Figure 6 As shown, the angle between the first stamping surface 111 and the second stamping surface 112 is a right angle, and the angle between the horizontal receiving surface 3111 and the forming surface 3112 is also a right angle. The formed forming groove 11 is a primary forming groove, and the formed forming protrusion 311 is a primary forming protrusion. This enables the strip 100 to be bent into a part having one or at least two right-angled bends in the same clockwise direction.

[0078] Alternatively, as Figure 6 As shown, the angle between the first stamping surface 111 and the second stamping surface 112 is obtuse, and the angle between the horizontal receiving surface 3111 and the forming surface 3112 is also obtuse. The formed forming groove 11 is a pre-formed groove, and the formed forming protrusion 311 is a pre-formed protrusion. This allows the strip 100 to be bent into a part having one or at least two obtuse-angled bends in the same clockwise direction.

[0079] Optionally, there are multiple forming grooves 11 and multiple forming protrusions 311, and the multiple forming grooves 11 and the multiple forming protrusions 311 are arranged in a one-to-one correspondence. The multiple forming grooves 11 include at least a pre-forming groove with an obtuse angle between the first stamping surface 111 and the second stamping surface 112, and a main forming groove with a right angle between the first stamping surface 111 and the second stamping surface 112. The multiple forming protrusions 311 include at least a pre-forming protrusion with an obtuse angle between the horizontal holding surface 3111 and the forming surface 3112, a main forming protrusion with a right angle between the horizontal holding surface 3111 and the forming surface 3112, and an adjustment protrusion with an acute angle between the horizontal holding surface 3111 and the forming surface 3112.

[0080] Specifically, the plurality of molding grooves 11 are divided into multiple groups of molding grooves, each group of molding grooves includes three molding grooves 11. The plurality of molding protrusions 311 are divided into multiple groups of molding protrusions. Each group of molding protrusions includes three molding protrusions 311. The multiple groups of molding grooves and the multiple groups of molding protrusions are arranged in a one-to-one correspondence.

[0081] Specifically, if Figure 2 、 Figure 4 、 Figure 6 and Figure 8 As shown, each set of forming grooves includes three forming grooves 11, one pre-forming groove, and two main forming grooves. Each set of forming protrusions includes three forming protrusions 311, one pre-forming protrusion, one main forming protrusion, and one adjustment protrusion. The pre-forming groove corresponds to the pre-forming protrusion, one main forming groove corresponds to the main forming protrusion, and the other main forming groove corresponds to the adjustment protrusion. When bending the strip 100, the pre-forming groove and the pre-forming protrusions first bend the area of ​​the strip 100 where it is intended to be bent at a right angle to form an obtuse angle. Then, one main forming groove and the main forming protrusion bend the obtuse angle of the strip 100 to a right angle. The other main forming groove and the adjustment protrusion then fine-tune the right-angle bend of the strip 100 to form the desired right-angle bend structure. This effectively improves the precision and quality of the bent parts. It is understood that the three forming grooves 11 and the three forming protrusions 311 operate synchronously, further improving the efficiency of the stamping die. Specifically, if Figure 2 、 Figure 4 、 Figure 6 and Figure 8As shown, a group of forming grooves and a group of forming protrusions are set as an example.

[0082] Specifically, the process of using a pre-formed groove and a pre-formed protrusion to bend the area on the strip 100 that is expected to be bent at a right angle into an obtuse angle, the process of using one of the main forming grooves and the main forming protrusion to bend the obtuse-angled bend on the strip 100 into a right angle, and the process of using another main forming groove and an adjustment protrusion to fine-tune the right-angled bend on the strip 100 are similar, so they will not be repeated here.

[0083] It is understood that the preformed grooves and preformed protrusions can also be used to bend the strip 100 separately. The strip 100 is bent to form a part having one or at least two obtuse bends in the same clockwise direction, further improving the versatility of the stamping die.

[0084] Preferably, if Figure 4 and Figure 8 As shown, the mounting base 2 is provided with a guide groove 21 extending along a first horizontal direction. The guide groove 21 is flush with the horizontal receiving surface 3111 of the formed protrusion 311 in the height direction. The horizontal receiving surface 3111 is used to receive the strip 100. The guide groove 21 is used to guide the strip 100 to move along the first horizontal direction. This allows the strip 100 to be quickly, efficiently, and accurately moved along the first horizontal direction to a desired position, and can limit the movement of the strip 100 to only along the first horizontal direction.

[0085] Among them, in this embodiment, Figure 1 、 Figure 3 、 Figure 5 and Figure 8 As shown, the exemplary upper die base assembly 4 includes an upper die base body 41, an upper pad 42, and an upper mold plate 43 connected in sequence from top to bottom along the height direction. One end of the forming punch 1 along the height direction is fixedly connected to the connection between the upper pad 42 and the upper mold plate 43. The first threaded hole is located at the end of the upper die base body 41 away from the upper pad 42 along the height direction. The first through hole passes through the pad 42 and the upper mold plate 43 along the height direction, and partially extends to the upper die base body 41 to communicate with the first threaded hole. Among them, the specific structure of the upper die base body 41, the upper pad 42, and the upper mold plate 43 belongs to the prior art and will not be repeated here.

[0086] Among them, in this embodiment, Figure 1 、 Figure 3 、 Figure 5 and Figure 8As shown, the stripper plate assembly 5 includes a stripper plate body 51 and a stripper cover plate 52. In the height direction, the stripper cover plate 52 is located between the stripper plate body 51 and the upper template 43. The end of the mechanical push rod that is not provided with the second inclined surface 321 is fixedly connected to the connection between the stripper plate body 51 and the stripper cover plate 52. Among them, the specific structure of the stripper plate body 51 and the stripper cover plate 52 belongs to the prior art and will not be repeated here.

[0087] Among them, in this embodiment, Figure 1 、 Figure 3 、 Figure 5 and Figure 8 As shown, the exemplary lower die base assembly 7 includes a lower die base body 71, a lower pad 72, and a lower mold plate 73 connected sequentially from bottom to top along the height direction. The upper end surface of the lower pad 72 along the height direction forms a limit surface 721. The second threaded hole is located at the end of the lower die base body 71 away from the lower pad 72 along the height direction. The second through hole passes through the lower pad 72 and the lower mold plate 73 along the height direction and partially extends into the lower die base body 71 to communicate with the second threaded hole. The specific structure of the lower die base body 71, the lower pad 72, and the lower mold plate 73 belongs to the prior art and will not be repeated here.
