[0002] In the field of hardware stamping and forming, the traditional bending and forming method is progressive step-by-step bending using a stamping die, that is, multiple hardware parts that need to be bent are processed simultaneously on the material strip.

[0040] This embodiment provides Figures 1 to 8 The hardware bending and forming mechanism shown is used for bending and forming hardware, comprising:

[0041] The lower die base 100, the bending die 200 and the extrusion assembly, the bending die 200 and the extrusion assembly are all installed on the lower die base 100, and the extrusion assembly is configured to be able to move in the direction close to or away from the bending die 200 to extrude or release a single hardware part between the bending die 200 and the extrusion assembly; the upper die base 400 and the inserting knife group, the upper die base 400 is installed on the lower die base 100 through a plurality of telescopic parts so that the upper die base 400 can move in the direction close to or away from the lower die base 100; the inserting knife group is installed on the upper die base 400 and can approach or move away from the lower die base 100 with the upper die base 400, and the inserting knife group is configured to drive the extrusion assembly to move in the direction close to the bending die 200 when it approaches the lower die base 100 with the upper die base 400; the ejector pin 600, the ejector pin 600 is installed on the lower die base 100, and is used to separate the formed hardware from the bending die 200.

[0042] When it is necessary to perform bending and forming of hardware with complex shapes, the hardware is first formed to the process before interference occurs, and then the hardware is sheared off for subsequent single-piece bending and forming; when performing single-piece bending and forming, the hardware is placed on the lower die base 100, and the forming mechanism is started to move the upper die base 400 toward the lower die base 100. The insert knife group installed on the upper die base 400 can drive the extrusion assembly to approach the bending die 200 to extrude and bend the hardware; when forming is completed, the upper die base 400 is away from the lower die base 100, and the ejector pin 600 separates the formed hardware from the bending die 200, and the entire hardware forming work is completed.

[0043] In this embodiment, the bending die 200 and the extrusion assembly are used to perform single bending forming on the hardware. The forming method is simple and can realize the bending forming of hardware with complex shapes. When bending and forming a single hardware, there is no need to process a large bending space on the material strip, so that the bending forming of hardware with complex shapes can be realized while the utilization rate of the material strip is high, which is less likely to cause material waste and improves the economy of the production process. The extrusion assembly is driven to move by the inserting knife group, and the driving method is simple and efficient. The formed hardware is separated from the bending die 200 by the ejector pin 600. The separation method is simple and fast, and no external tools are required, which further reduces the production cost.

[0044] Preferably, if Figure 6 As shown, in this embodiment, a plurality of first limit members 101 are further provided on the lower mold base 100 , and the plurality of first limit members 101 are located between the upper mold base 400 and the lower mold base 100 , and are used to limit the minimum distance between the upper mold base 400 and the lower mold base 100 .

[0045] like Figure 1 and Figure 6 As shown, in this embodiment, the extrusion assembly includes a first molding assembly 310 and a second molding assembly 320. A first chute 110 and a second chute 120 are formed on the lower die base 100. The first molding assembly 310 and the second molding assembly 320 are slidably mounted in the first chute 110 and the second chute 120, respectively. The first molding assembly 310 and the second molding assembly 320 can bend the hardware into different shapes to meet production needs. The first chute 110 and the second chute 120 provide movement trajectories for the first molding assembly 310 and the second molding assembly 320, respectively, so that the first molding assembly 310 and the second molding assembly 320 can be installed along the predetermined trajectory and move accurately toward the bending die 200, avoiding errors in the movement process and ensuring the accuracy of the bending forming of the hardware.

[0046] like Figure 1 and Figure 5 As shown, in this embodiment, the blade assembly includes a first blade 510 and a second blade 520. One end of the first blade 510 is configured to be inserted into the first chute 110 to drive the first forming assembly 310 to move along the first chute 110 toward the bending die 200. One end of the second blade 520 is configured to be inserted into the second chute 120 to drive the second forming assembly 320 to move along the second chute 120 toward the bending die 200. The first and second blades 510, 520 can drive the first and second forming assemblies 310, 320 to move toward the bending die 200 synchronously or asynchronously according to production requirements to bend the hardware, thereby improving the flexibility of the hardware bending process. The first and second blades 510, 520 respectively drive the first and second forming assemblies 310, 320, providing a simple driving method and low operational difficulty.

[0047] like Figure 3 As shown, in this embodiment, the first forming assembly 310 includes a first driving member 311 and a first forming block 312, and the first forming block 312 is installed on the first driving member 311; the first driving member 311 is slidably installed in the first slide groove 110, and is configured to drive the first forming block 312 to move in a direction away from the bending die 200 when the first plunger 510 is away from the first slide groove 110; the second forming assembly 320 includes a second driving member 321 and a second forming block 322, and the second forming block 322 is installed on the second driving member 321; the second driving member 321 is slidably installed in the second slide groove 120, and is configured to drive the second forming block 322 to move in a direction away from the bending die 200 when the second plunger 520 is away from the second slide groove 120. The first driving member 311 and the second driving member 321 provide stable driving force for the first forming block 312 and the second forming block 322 respectively. When the first inserting knife 510 is disengaged from the first sliding groove 110, the first forming block 312 and the second forming block 322 can be stably driven away from the bending die 200, thereby relieving the squeezing of the first forming block 312, the second forming block 322 and the bending die 200 on the hardware, thereby facilitating the separation of the hardware from the bending die 200.

[0048] Preferably, if Figure 5 As shown, in this embodiment, the first limiting hole 3121 and the second limiting hole 3221 are respectively provided on the first forming block 312 and the second forming block 322, and the first limiting block 102 and the second limiting block 103 are provided on the lower mold base 100. The first limiting hole 3121 and the first limiting block 102 cooperate with each other to limit the moving distance of the first forming block 312 on the lower mold base 100, thereby avoiding damage caused by excessive movement of the first forming block 312; the second limiting hole 3221 and the second limiting block 103 cooperate with each other to limit the moving distance of the second forming block 322 on the lower mold base 100, thereby avoiding damage caused by excessive movement of the second forming block 322.

[0049] More preferably, in this embodiment, the first plunger 510 and the second plunger 520 have the same length. When the upper die base 400 approaches the lower die base 100, the first plunger 510 and the second plunger 520 can drive the first forming assembly 310 and the second forming assembly 320 to move synchronously toward the bending die 200; when the upper die base 400 moves away from the lower die base 100, the first plunger 510 and the second plunger 520 can synchronously disengage from the first slide groove 110 and the second slide groove 120, so that the first forming assembly 310 and the second forming assembly 320 can synchronously move away from the bending die 200.

[0050] like Figures 1 to 4As shown, in this embodiment, a positioning member 330 is provided between the first forming assembly 310 and the second forming assembly 320. A positioning slot 130 is formed on the lower die base 100, and the positioning member 330 is slidably mounted within the positioning slot 130. The insert assembly further includes a positioning insert 530, one end of which is configured to be inserted into the positioning slot 130 to drive the positioning member 330 to move within the positioning slot 130 toward the bending die 200, thereby positioning the hardware on the bending die 200. The positioning member 330 can position the hardware on the bending die 200, preventing the hardware from shifting during processing and ensuring the accuracy of hardware processing. The positioning slot 130 provides a precise trajectory for the movement of the positioning member 330, preventing position deviation during movement of the positioning member 330, which could result in inaccurate positioning.

[0051] like Figure 4 and Figure 8 As shown, in this embodiment, a positioning pin 331 is formed on the positioning member 330, a first positioning hole 910 is formed on the hardware, and a second positioning hole 210 is formed on the bending die 200. The positioning pin 331, the first positioning hole 910, and the second positioning hole 210 cooperate with each other to position the hardware on the bending die 200. The cooperation between the positioning pin 331, the first positioning hole 910, and the second positioning hole 210 helps ensure that the hardware always maintains a fixed position during the bending process, is less likely to deviate or wobble, and improves the stability of the bending process.

[0052] Preferably, if Figure 4 As shown, in this embodiment, the positioning member 330 includes a positioning drive member 332 and a positioning head 333. When the positioning insert 530 is disengaged from the positioning slot 130, the positioning drive member 332 can drive the positioning head 333 away from the bending die 200; the positioning pin 331 is formed on the positioning head 333.

[0053] Better, if Figure 4 As shown, in this embodiment, a third limiting hole 3331 is formed on the positioning head 333, and a third limiting block 104 is provided on the lower mold base 100. The third limiting block 104 and the third limiting hole 3331 cooperate with each other to limit the moving distance of the positioning head 333 on the lower mold base 100, thereby avoiding damage caused by excessive movement of the positioning head 333.

[0054] like Figure 3 and Figure 4As shown, in this embodiment, the lower die base 100 is provided with a positioning block 700 and a sensing element 800. The positioning block 700 is used to position the hardware on the lower die base 100 and is controllably connected to the sensing element 800. The sensing element 800 is configured to sense the position of the positioning insert 530 within the positioning slot 130 and control the extension or retraction of the positioning block 700 within the lower die base 100. The positioning block 700 provides precise positioning for the hardware on the lower die base 100, reducing errors caused by inaccurate hardware positioning. The sensing element 800 controls the extension or retraction of the positioning block 700, automating the operation of the positioning block 700, simplifying the process of placing hardware on the lower die base 100, and improving production efficiency.

[0055] Preferably, if Figure 2 As shown, in this embodiment, the lower die base 100 is further provided with a cylinder 105 for driving the positioning block 700 to extend or retract the lower die base 100. The cylinder 105 is respectively controlled and connected with the sensing element 800 and the positioning block 700. When the positioning insert 530 is not inserted into the positioning slide groove 130, the cylinder 105 controls the positioning block 700 to extend out of the lower die base 100 so that the staff can install the hardware on the lower die base 100 through the positioning block 700; the lower die base 100 is also provided with a pin 600 for driving the bent hardware to be ejected from the bending die 200, so that the formed hardware can be separated from the bending die 200.

[0056] Better, if Figure 2 As shown, in this embodiment, a sensing strip 531 is formed on the positioning blade 530 . The sensing strip 531 extends along the length of the positioning blade 530 , and the length of the sensing strip 531 is less than the length of the positioning blade 530 . The sensing element 800 is configured to sense the position of the sensing strip 531 . The upper die base 400 moves toward the lower die base 100, and the positioning insert 530 is inserted into the positioning slot 130 to cause the positioning member 330 to move toward the bending die 200 and abut against the hardware. Then, the positioning insert 530 continues to move toward the lower die base 100 so that the sensing bar 531 can be sensed by the sensing member 800. When the sensing member 800 senses the sensing bar 531, a signal is sent to cause the cylinder 105 to control the positioning block 700 to retract into the lower die base 100. When the hardware is formed, the upper die base 400 moves away from the lower die base 100, and the positioning insert 530 is disengaged from the positioning slot 130. When the sensing member 800 no longer senses the sensing bar 531, a signal is sent to cause the cylinder 105 to control the positioning block 700 to extend out of the lower die base 100 so that the staff can place the next hardware.

[0057] like Figure 1 and Figure 6As shown, in this embodiment, the extrusion assembly further includes a third forming assembly 340 and a fourth forming assembly 350. A third chute 140 and a fourth chute 150 are formed on the lower die base 100.

The third chute 140 and the fourth chute 150 provide movement trajectories for the third forming assembly 340 and the fourth forming assembly 350, respectively, so that the third forming assembly 340 and the fourth forming assembly 350 can be accurately moved toward the bending die 200 along the predetermined trajectory, avoiding errors in the movement process and ensuring the accuracy of the bending forming of the hardware.

[0058] like Figure 1 As shown, in this embodiment, the blade assembly further includes a third blade 540 and a fourth blade 550. One end of the third blade 540 is configured to be inserted into the third chute 140 to drive the third forming assembly 340 along the third chute 140 toward the bending die 200. One end of the fourth blade 550 is configured to be inserted into the fourth chute 150 to drive the fourth forming assembly 350 along the fourth chute 150 toward the bending die 200. The third and fourth blades 540, 550 can drive the third and fourth forming assemblies 340, 350 toward the bending die 200 synchronously or asynchronously, depending on production requirements, to bend the hardware component, thereby enhancing the flexibility of the hardware bending process. The third and fourth blades 540, 550 drive the third and fourth forming assemblies 340, 350, respectively, providing a simple driving method and low operational difficulty.

[0059] like Figure 5As shown, in this embodiment, the third forming assembly 340 includes a third driving member 341 and a third forming block 342, and the third forming block 342 is installed on the third driving member 341; the third driving member 341 is slidably installed in the third slide groove 140, and is configured to drive the third forming block 342 to move in a direction away from the bending die 200 when the third plunger 540 is away from the third slide groove 140; the fourth forming assembly 350 includes a fourth driving member 351 and a fourth forming block 352, and the fourth forming block 352 is installed on the fourth driving member 351; the fourth driving member 351 is slidably installed in the fourth slide groove 150, and is configured to drive the fourth forming block 352 to move in a direction away from the bending die 200 when the fourth plunger 550 is away from the fourth slide groove 150. The third driving member 341 and the fourth driving member 351 provide stable driving force for the third forming block 342 and the fourth forming block 352 respectively. When the third plunger 540 is disengaged from the third slide groove 140, the third forming block 342 and the fourth forming block 352 can be stably driven away from the bending die 200, thereby relieving the squeezing of the third forming block 342, the fourth forming block 352 and the bending die 200 on the hardware, thereby facilitating the separation of the hardware from the bending die 200.

[0060] Preferably, in this embodiment, the third plunger 540 and the fourth plunger 550 have the same length. When the upper die base 400 approaches the lower die base 100, the third plunger 540 and the fourth plunger 550 can drive the third forming assembly 340 and the fourth forming assembly 350 to move synchronously toward the bending die 200; when the upper die base 400 moves away from the lower die base 100, the third plunger 540 and the fourth plunger 550 can synchronously disengage from the third slide groove 140 and the fourth slide groove 150, so that the third forming assembly 340 and the fourth forming assembly 350 can synchronously move away from the bending die 200.

[0061] Better, if Figure 1 As shown, in this embodiment, the first molding component 310, the positioning member 330 and the second molding component 320 are covered with a first protective plate 360 ​​for protecting the first molding component 310, the positioning component and the second molding component 320 from being hit by external parts; the third molding component 340 and the fourth molding component 350 are respectively covered with a second protective plate 370 and a third protective plate 380 for protecting the third molding component 340 and the fourth molding component 350 from being hit by external parts.
