Description

Technical Field

[0001] This utility model relates to the field of hardware stamping die technology, and in particular to a hardware stamping die that is easy to replace. Background Technology

[0002] Hardware parts generally refer to metal fittings and components used in fields such as construction, furniture, and machinery. In modern manufacturing, stamping technology is widely used in the production of hardware parts. During use, when it is necessary to stamp hardware parts of different specifications, it is necessary to replace the hardware stamping die. Therefore, a hardware stamping die that is easy to replace is required.

[0003] To improve stability, traditional metal stamping dies are typically installed and fixed using bolts and nuts. When the die needs to be replaced, multiple bolts and nuts must be removed one by one, and then reinstalled after replacing the die. This process is time-consuming and reduces work efficiency. With frequent die replacements, the bolts and nuts are prone to wear or damage due to repeated operations, and maintaining and replacing these parts also requires additional time and costs. Utility Model Content

[0004] The purpose of this utility model is to address the shortcomings of existing technologies by proposing a hardware stamping die that is easy to replace.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A replaceable stamping die for hardware parts includes a base. Four L-shaped plates are symmetrically fixed at the top center of the base. The inner sidewalls of the four L-shaped plates are provided with the same mounting base. The outer sidewalls of the four L-shaped plates are each provided with a fixing mechanism for fixing the mounting base. A lower die is fixed at the top center of the mounting base. A U-shaped plate is slidably connected to the inner sidewall of the lower die. Two symmetrical inner sidewalls of the mounting base are each provided with a lifting mechanism for lifting the U-shaped plate. A U-shaped frame is fixed at the top center of the base. A connecting plate is provided at the top of the U-shaped frame. An upper die is provided at the bottom of the connecting plate. The top of the upper die is... The device is equipped with a snap-fit ​​mechanism for engaging the upper mold, and a lifting mechanism for raising and lowering the connecting plate is provided on the top of the U-shaped frame. During use, the design of the fixing mechanism and the snap-fit ​​mechanism simplifies the mold installation and replacement process, avoiding the traditional bolt and nut locking method, making mold replacement faster and more efficient. The entire installation and replacement process does not require complicated tools or techniques, reducing the difficulty of operation and improving work efficiency. After stamping, the design of the lifting mechanism allows the stamped hardware to be automatically ejected from the lower mold, making it convenient for workers to pick up, thus improving the practicality of the device.

[0007] As a further embodiment of this utility model, the fixing mechanism includes a sleeve, which is disposed through the outer wall of one of the L-shaped plates of the base. A first circular block is slidably connected to the inner wall of the sleeve. A column is fixed to one end of the first circular block and passes through one end of the sleeve. A connecting rod is fixed to the other end of the first circular block and passes through the other end of the sleeve. A first spring is sleeved on the side wall of the connecting rod. A through hole is opened on the side wall of the L-shaped plate and is adapted to the column. Pulling the four connecting rods causes the four first circular blocks to move along the inner walls of the four sleeves respectively until the four columns are retracted into the four sleeves. At this time, the four first springs are all in a compressed state. Then, the mounting base is placed on the top of the base and placed inside the four L-shaped plates. When the four connecting rods are released, the four first circular blocks are pushed to move in the opposite direction under the reaction of the four compressed first springs, thereby pushing the four columns into the four through holes respectively, thus completing the installation of the lower mold.

[0008] As a further embodiment of this utility model, the snap-fit ​​mechanism includes a rectangular block, which is fixed to the top of the upper mold. A rectangular hole is provided in the middle of the top of the connecting plate, and the rectangular hole is adapted to the upper mold. Rectangular grooves are provided on both symmetrical side walls of the rectangular block, and both rectangular grooves are constricted structures. Second sliders are slidably connected to the inner side walls of the two rectangular grooves. A snap-fit ​​block is fixed to the outer side wall of the two second sliders. A third spring is provided inside the two rectangular grooves. Pressing the two snap-fit ​​blocks causes the two third springs to move closer to each other along the inner side walls of the two rectangular grooves until the two snap-fit ​​blocks are retracted into the two rectangular grooves. At this time, the two third springs are in a compressed state. Then, the rectangular block is inserted into the rectangular hole. When the two snap-fit ​​blocks are both above the connecting plate, the reaction force of the two compressed third springs pushes the two second sliders away from each other until one end of the two snap-fit ​​blocks is outside the two rectangular grooves, thus completing the installation of the upper mold.

[0009] As a further embodiment of this utility model, the lifting mechanism includes two hydraulic push rods, which are symmetrically fixed at both ends of the top of the U-shaped frame. The output ends of both hydraulic push rods are fixed to the connecting plate. The lifting mechanism includes a circular slide groove, which is located inside one end of the lower mold. A through groove is formed on the inner sidewall of one end of the lower mold, and the through groove communicates with the circular slide groove. A second circular block is slidably connected to the inner sidewall of the circular slide groove. A first slider is slidably connected to the sidewall of the through groove. One end of the first slider is fixed to the second circular block, and the other end of the first slider is fixed to the U-shaped plate. A second spring is installed inside the circular slide groove, located below the second circular block. The two hydraulic push rods drive the connecting plate downwards, thereby moving the upper mold downwards. When the upper mold... When the die enters the lower mold, stamping can begin. During stamping, the forming plate is compressed and moves downward along the inner wall of the lower mold. This, combined with the two first sliders, drives the two second circular blocks to move downward along the inner walls of the two circular grooves until the forming plate stops moving, thus completing the stamping process. At this point, both second springs are in a compressed state. After the stamping process is completed, the two hydraulic push rods are driven to move the upper mold upward, causing the upper mold to gradually separate from the lower mold. During the separation process, the pressure on the forming plate gradually decreases. Under the reaction of the two compressed second springs, the two second circular blocks are pushed to move in the opposite direction, which in turn pushes the forming plate upward along the inner wall of the lower mold, ejecting the stamped hardware from the lower mold for easy pickup by workers, thus increasing the practicality of the device.

[0010] The beneficial effects of this utility model are as follows:

[0011] 1. During use, the design of the fixing mechanism and the snap-fit ​​mechanism of this device simplifies the installation and replacement process of the mold, avoiding the traditional bolt and nut locking method, making the mold replacement faster and more efficient. The entire installation and replacement process does not require complicated tools or techniques, reducing the difficulty of operation and improving work efficiency.

[0012] 2. After stamping, the design of the lifting mechanism allows the stamped hardware parts to be automatically ejected from the lower mold, making it convenient for workers to pick them up and improving the practicality of the device. Attached Figure Description

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0024] Reference Figures 1-9A replaceable stamping die for hardware parts includes a base 1. Four L-shaped plates 4 are symmetrically fixed at the top center of the base 1. The inner walls of the four L-shaped plates 4 are provided with the same mounting seat 6. The outer walls of the four L-shaped plates 4 are each provided with a fixing mechanism for fixing the mounting seat 6. A lower die 7 is fixed at the top center of the mounting seat 6. A U-shaped plate 14 is slidably connected to the inner wall of the lower die 7. Two symmetrical inner walls of the mounting seat 6 are each provided with a lifting mechanism for lifting the U-shaped plate 14. A U-shaped frame 2 is fixed at the top center of the base 1. A connecting plate 8 is provided at the top of the U-shaped frame 2. An upper die 20 is provided at the bottom of the connecting plate 8. The top of the upper die 20... The device is equipped with a snap-fit ​​mechanism for snapping onto the upper mold 20, and a lifting mechanism for lifting the connecting plate 8 on the top of the U-shaped frame 2. During use, the design of the fixing mechanism and the snap-fit ​​mechanism simplifies the installation and replacement process of the mold, avoiding the traditional bolt and nut locking method, making the mold replacement faster and more efficient. The entire installation and replacement process does not require complicated tools or techniques, reducing the difficulty of operation and improving work efficiency. After stamping, the design of the lifting mechanism allows the stamped hardware to be automatically ejected from the lower mold 7, making it convenient for workers to pick up, thus improving the practicality of the device.

[0025] In this embodiment, the fixing mechanism includes a sleeve 5, which is disposed through the outer wall of one of the L-shaped plates 4 of the base 1. A first circular block 9 is slidably connected to the inner wall of the sleeve 5. A column 10 is fixed to one end of the first circular block 9 and passes through one end of the sleeve 5. A connecting rod 11 is fixed to the other end of the first circular block 9 and passes through the other end of the sleeve 5. A first spring 12 is sleeved on the side wall of the connecting rod 11. A through hole 13 is opened on the side wall of the L-shaped plate 4 and is adapted to the column 10. Pulling the four connecting rods 11 This causes the four first circular blocks 9 to move along the inner walls of the four sleeves 5 respectively, until the four pillars 10 are retracted into the four sleeves 5 respectively. At this time, the four first springs 12 are all in a compressed state. Then, the mounting seat 6 is placed on top of the base 1, and the mounting seat 6 is placed inside the four L-shaped plates 4. After releasing the four connecting rods 11, under the reaction action of the four compressed first springs 12, the four first circular blocks 9 are pushed to move in the opposite direction, thereby pushing the four pillars 10 into the four through holes 13 respectively, thus completing the installation of the lower mold 7.

[0026] In this embodiment, the locking mechanism includes a rectangular block 22, which is fixed to the top of the upper mold 20. A rectangular hole 21 is provided at the center of the top of the connecting plate 8, and the rectangular hole 21 is adapted to the upper mold 20. Rectangular grooves 23 are provided on both symmetrical side walls of the rectangular block 22, and both rectangular grooves 23 are constricted structures. Second sliders 24 are slidably connected to the inner side walls of both rectangular grooves 23. Locking blocks 25 are fixed to the outer side walls of both second sliders 24. Third springs 26 are provided inside both rectangular grooves 23 to press the two locking blocks 25. The two third springs 26 are brought closer to each other along the inner walls of the two rectangular slides 23 until the two locking blocks 25 are retracted into the two rectangular slides 23. At this time, the two third springs 26 are in a compressed state. Then, the rectangular block 22 is inserted into the rectangular hole 21. When the two locking blocks 25 are both above the connecting plate 8, the two second sliders 24 are pushed away from each other by the reaction of the two compressed third springs 26 until one end of the two locking blocks 25 is located outside the two rectangular slides 23, thus completing the installation of the upper mold 20.

[0027] In this embodiment, the lifting mechanism includes two hydraulic push rods 3, which are symmetrically fixed at both ends of the top of the U-shaped frame 2. The output ends of the two hydraulic push rods 3 are fixed to the connecting plate 8. The lifting mechanism includes a circular slide groove 16, which is opened inside one end of the lower mold 7. A through groove 15 is opened on the inner side wall of one end of the lower mold 7, and the through groove 15 and the circular slide groove 16 are connected. A second circular block 17 is slidably connected to the inner side wall of the circular slide groove 16. A first slider 19 is slidably connected to the side wall of the through groove 15. One end of the first slider 19 is fixed to the second circular block 17, and the other end of the first slider 19 is fixed to the U-shaped plate 14. A second spring 18 is provided inside the circular slide groove 16, and the second spring 18 is located below the second circular block 17. The two hydraulic push rods 3 drive the connecting plate 8 to move downward, thereby driving the upper mold 20 to move downward. When the upper mold 20 enters the lower mold... When the die is inside the mold 7, stamping can begin. During the stamping process, the forming plate 14 is compressed and moves downward along the inner wall of the lower mold 7. This, along with the two first sliders 19, drives the two second circular blocks 17 to move downward along the inner walls of the two circular grooves 16 until the forming plate 14 stops moving, thus completing the stamping process. At this time, both second springs 18 are in a compressed state. After the stamping process is completed, the two hydraulic push rods 3 drive the upper mold 20 to move upward, causing the upper mold 20 to gradually separate from the lower mold 7. During the separation process, the pressure on the forming plate 14 gradually decreases. Under the reaction of the two compressed second springs 18, the two second circular blocks 17 are pushed to move in the opposite direction, thereby pushing the forming plate 14 upward along the inner wall of the lower mold 7, ejecting the stamped hardware parts out of the lower mold 7 for easy pickup by workers, thus increasing the practicality of the device.

[0028] Working Principle: During the use of this device, when installing the mold, the mounting base 6 is pre-fixed to the lower mold 7 and the connecting plate 8 to the rectangular block 22. When installing the lower mold 7, by pulling the four connecting rods 11, the four first circular blocks 9 move along the inner walls of the four sleeves 5 respectively until the four columns 10 retract into the four sleeves 5. At this time, the four first springs 12 are all in a compressed state. Then, the mounting base 6 is placed on top of the base 1, so that the mounting base 6 is inside the four L-shaped plates 4. When the four connecting rods 11 are released, under the reaction action of the four compressed first springs 12, the four first circular blocks 9 are pushed to move in the opposite direction, thereby pushing... The four uprights 10 are inserted into the four through holes 13 to complete the installation of the lower mold 7. When installing the upper mold 20, first press the two locking blocks 25, causing the two third springs 26 to move closer together along the inner walls of the two rectangular slides 23 until the two locking blocks 25 are retracted into the two rectangular slides 23. At this point, both third springs 26 are compressed. Then, insert the rectangular block 22 into the rectangular hole 21. When both locking blocks 25 are above the connecting plate 8, the reaction force of the two compressed third springs 26 pushes the two second sliders 24 away from each other until one end of each locking block 25 is located in the two rectangular slides 23. The upper mold 20 can be installed outside the shaped slide groove 23. The entire process eliminates the traditional bolt and nut locking method, making operation simple and convenient for installing or replacing the lower mold 7 and the upper mold 20. During stamping, the metal material is placed on top of the lower mold 7, and the two hydraulic push rods 3 drive the connecting plate 8 to move downward, thereby driving the upper mold 20 to move downward. When the upper mold 20 enters the interior of the lower mold 7, the stamping work can be carried out. During the stamping process, the return plate 14 is squeezed and moves downward along the inner wall of the lower mold 7, cooperating with the two first sliders 19 to drive the two second circular blocks 17 to move along the two circular slide grooves 1 respectively. The inner wall of the die 6 moves downward until the forming plate 14 stops moving, thus completing the stamping process. At this time, both second springs 18 are in a compressed state. After the stamping process is completed, the two hydraulic push rods 3 drive the upper mold 20 to move upward, so that the upper mold 20 gradually separates from the lower mold 7. During the separation process, the pressure on the forming plate 14 gradually decreases. Under the reaction of the two compressed second springs 18, the two second circular blocks 17 are pushed to move in the opposite direction, thereby pushing the forming plate 14 to move upward along the inner wall of the lower mold 7, pushing the stamped hardware out of the lower mold 7 for easy picking by workers, thus increasing the practicality of the device.

[0029] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
