Description

Technical Field

[0001] The utility model relates to the field of hardware stamping processing, in particular to a hardware die with a continuous stamping structure. Background Art

[0002] Metal stamping dies are key tools widely used in industrial production. They apply pressure to metal or non-metallic sheets through the die to separate or shape the materials, thereby manufacturing parts that meet the requirements. Depending on the process and structure, metal stamping dies can be divided into many types, such as blanking dies, bending dies, drawing dies, etc.

[0003] In the process of metal stamping, the metal coil is usually passed through the use of an unwinder and a rewinder, and the servo motor is used to realize the stepping process of the metal coil, so that the external stamping device can perform continuous stamping operations on the metal coil. However, there is a problem in actual use. Specifically, when the metal coil passes through the stamping platform, the front and rear sections may pull the position to be stamped, causing the metal coil to be in a certain bending state. This form reduces the stamping accuracy and convenience of the metal coil. Utility Model Content

[0004] Based on this, the purpose of this utility model is to provide a hardware mold with a continuous stamping structure to solve the technical problem that during traditional stamping of metal coils, the metal coil sheets have certain flexibility, and the metal coils have certain bending before pre-stamping, which leads to reduced stamping accuracy.

[0005] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a hardware mold with a continuous stamping structure, comprising a stamping machine body, a stamping rod, a support platform, and a metal sheet, an upper mold being provided at the bottom of the stamping rod, a lower mold being provided at the top of the support platform, two sets of limiting mechanisms being provided on both sides of the lower mold, the limiting mechanism comprising a slide groove, a mounting frame being engaged and slidably provided inside the slide groove, a limiting plate being provided on the mounting frame through rotation of a rotating shaft, a support rod being provided through rotation of a torsion rotating shaft, and a pressure roller being provided on the other side of the support rod.

[0006] By adopting the above technical solution, the limit plates on both sides of the mold are used to provide firm support for the metal sheet to be stamped, ensuring that the metal sheet will not move or deflect unnecessarily before stamping. At the same time, the torque generated by the torsion shaft drives the pressing roller to perform moderate pressing operations on the metal sheet, which not only further limits the position of the metal sheet, but also ensures a close fit between the metal sheet and the lower mold.

[0007] Furthermore, the mounting frame is bolted to the support platform, and the slide groove is used to adjust the lateral position of the mounting frame.

[0008] By adopting the above technical solution, the stability and firmness of the mounting frame on the support platform are ensured, providing a reliable support foundation for subsequent stamping operations. The bolt connection method also makes the installation and disassembly process relatively simple, which is conducive to equipment maintenance and debugging.

[0009] Furthermore, the transverse surface of the limiting plate is in an arc structure, the metal sheet is in contact with the limiting plate and is in a tangent structure, and the highest point of the limiting plate is in a horizontal structure with the top surface of the lower mold.

[0010] By adopting the above technical solution, the limiting plate can better fit the shape of the metal sheet and provide stable support for the metal sheet. When the metal sheet and the limiting plate are in contact, a tangent structure is formed between them. This structure ensures that the metal sheet can maintain a fixed position before stamping and will not be offset due to external force, thereby improving the stamping accuracy.

[0011] Furthermore, an adjustment groove is provided on the surface of the mounting frame, a fastening handwheel is threadedly connected to the limit plate, and the fastening handwheel passes through the mounting frame through the adjustment groove, for fixing the installation angle of the limit plate.

[0012] By adopting the above technical solution, the existence of the adjustment slot means that the limit plate can not only be adjusted in the horizontal direction, but also can be finely adjusted upwards.

[0013] Furthermore, the pressing roller contacts the metal sheet and forms an adaptive mechanism through the torsion shaft.

[0014] By adopting the above technical solution, it is ensured that the pressing roller can effectively apply pressure to the metal sheet, thereby limiting its position. The pressing effect not only prevents the metal sheet from moving or offsetting before stamping, but also improves the fit between the metal sheet and the lower mold, providing a stable foundation for subsequent stamping operations.

[0015] Furthermore, the two sets of limiting mechanisms on one side of the support platform are mirror-image structures, and the distance between them is adapted to the width of the metal sheet.

[0016] By adopting the above technical solution, the functional consistency of the two sets of limiting mechanisms is ensured, which means that the two sets of limiting mechanisms can limit the two sides of the metal sheet in the same way, thereby improving the uniformity and stability of the limitation.

[0017] In summary, the present invention has the following beneficial effects:

[0018] 1. The utility model uses the limiting plates on both sides to support the metal sheet to be stamped through the limiting mechanism. This operation ensures that the metal sheet can maintain a stable position before stamping and will not move due to external factors. At the same time, the torsion of the torsion shaft causes the pressing roller to press the metal sheet. This step further limits the metal sheet on the lower mold, ensuring that the metal sheet and the lower mold fit closely. Since the top of the limiting plate is horizontally aligned with the top of the lower mold, the metal sheet can be limited to fit the top surface of the lower mold. This effect is conducive to making the metal sheet placed on the lower mold flush with the lower mold, thereby reducing the bending degree of the metal sheet, improving the stamping accuracy of the metal sheet, and ensuring that the stamped product meets the quality requirements;

[0019] 2. The utility model sets a limit mechanism. Before stamping, the user can easily adjust the distance between the two sets of limit mechanisms on one side according to the actual width of the metal sheet through the sliding function of the slide groove, so that the equipment can adapt to metal sheets of different widths, improve the applicability of stamping processing to metal sheets of different specifications, thereby enhancing the flexibility and versatility of the equipment. At the same time, through the setting of the rotating shaft, the user can rotate the limit plate at an angle. After adjusting it into place, the limit plate can be fixed with a tightening handwheel, so that the installation angle of the limit plate can be flexibly adjusted according to different models and types of lower molds, further improving the environmental applicability of the equipment.

For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0028] The following describes an embodiment of the present invention based on its overall structure.

[0029] Example 1:

[0030] A hardware mold with a continuous stamping structure, such as Figures 1-4As shown, it includes a punching machine body 1, a punching rod 2, a support platform 3, and a metal sheet 5. The bottom of the punching rod 2 is provided with an upper mold 402, the top of the support platform 3 is provided with a lower mold 401, and two sets of limiting mechanisms 6 are provided on both sides of the lower mold 401. The limiting mechanism 6 includes a slide 601, and the internal engaging and sliding of the slide 601 is provided with a mounting frame 602. The mounting frame 602 is provided with a limiting plate 603 that is rotated by a rotating shaft 604, and a support rod 607 that is rotated by a torsion rotating shaft 608. A pressing roller 609 is rotatably provided on the other side of the support rod 607. The limiting plates 603 on both sides of the mold are used to firmly support the metal sheet 5 to be punched. The support ensures that the metal sheet 5 will not move or deflect unnecessarily before stamping. At the same time, the torque generated by the torsion shaft 608 drives the pressing roller 609 to perform a moderate pressing operation on the metal sheet 5, which not only further limits the position of the metal sheet 5, but also ensures a close fit between the metal sheet and the lower mold 401. Since the top end of the limiting plate 603 is adjusted to be horizontally aligned with the top of the lower mold 401, the metal sheet 5 can be accurately limited to a position that fits the top surface of the lower mold 401, which promotes the flushness between the metal sheet 5 and the lower mold 401, thereby effectively reducing the degree of bending of the metal sheet 5 during the stamping process.

[0031] See Figure 1 、 Figure 3 The mounting frame 602 is bolted to the support platform 3, and the slide 601 is used to adjust the lateral position of the mounting frame 602, ensuring the stability and firmness of the mounting frame 602 on the support platform 3, providing a reliable support foundation for subsequent stamping operations, and the bolt connection method also makes the installation and disassembly process relatively simple, which is beneficial to the maintenance and debugging of the equipment. At the same time, the slide 601 is used to adjust the lateral position of the mounting frame 602, so that the mounting frame 602 can be flexibly moved laterally within the range of the slide 601 according to actual needs. This adjustability not only meets the stamping requirements of metal sheets 5 of different specifications, but also improves the versatility and adaptability of the equipment.

[0032] See Figure 3 、 Figure 4The cross-street surface of the limiting plate 603 is an arc structure, and the metal sheet 5 is in contact with the limiting plate 603 and is in a tangent structure. The highest point of the limiting plate 603 is in a horizontal structure with the top surface of the lower mold 401, so that the limiting plate 603 can better fit the shape of the metal sheet 5 and provide stable support for the metal sheet 5. When the metal sheet 5 is in contact with the limiting plate 603, a tangent structure is formed between them. This structure ensures that the metal sheet 5 can maintain a fixed position before stamping and will not be offset due to external force, thereby improving the stamping accuracy. At the same time, the highest point of the limiting plate 603 is adjusted to a horizontal structure with the top surface of the lower mold 401, ensuring that the metal sheet 5 can remain parallel to the top surface of the lower mold 401 under the support of the limiting plate 603, thereby avoiding errors caused by bending of the metal sheet 5 during the stamping process.

[0033] Example 2:

[0034] See Figure 3 、 Figure 4 An adjusting slot 605 is provided on the surface of the mounting frame 602, and a fastening handwheel 606 is threadedly connected to the limit plate 603, and the fastening handwheel 606 passes through the mounting frame 602 through the adjusting slot 605, and is used to fix the installation angle of the limit plate 603. The existence of the adjusting slot 605 means that the limit plate 603 can not only be adjusted in the horizontal direction, but also can be finely adjusted in the upward direction. At the same time, the fastening handwheel 606 is threadedly connected to the limit plate 603, so that the user can easily fix or adjust the position and angle of the limit plate 603 by rotating the fastening handwheel 606.

[0035] See Figure 3 、 Figure 4 The pressing roller 609 is in contact with the metal sheet 5, and forms an adaptive mechanism through the torsion shaft 608, which ensures that the pressing roller 609 can effectively apply pressure to the metal sheet 5, thereby limiting its position. The pressing effect not only prevents the metal sheet 5 from moving or offsetting before stamping, but also improves the fit between the metal sheet 5 and the lower mold 401, providing a stable foundation for subsequent stamping operations. At the same time, the pressing roller 609 forms an adaptive mechanism through the torsion shaft 608, which means that the pressing roller 609 can be adaptively adjusted according to the thickness and shape of the metal sheet 5 to ensure the optimization of the pressing effect. The torsion provided by the torsion shaft 608 enables the pressing roller 609 to maintain sufficient pressing force while adapting to slight changes in the metal sheet 5, avoiding stamping errors caused by pressing too tightly or too loosely.

[0036] See Figure 1 、 Figure 2The two sets of limiting mechanisms 6 on one side of the support platform 3 are mirror-image structures, and the distance between them is adapted to the width of the metal sheet 5, ensuring the functional consistency of the two sets of limiting mechanisms 6, which means that the two sets of limiting mechanisms 6 can limit the two sides of the metal sheet 5 in the same way, thereby improving the uniformity and stability of the limitation. At the same time, the distance between the two sets of limiting mechanisms 6 is carefully adjusted to match the width of the metal sheet 5, ensuring that the metal sheet 5 can be clamped by the two sets of limiting mechanisms 6 when placed on the support platform 3, and the metal sheet 5 will not be offset due to the large distance, nor will it be squeezed unnecessarily due to the small distance.

[0037] The implementation principle of the present invention is as follows: the metal coil is step-by-step wound by an external unwinder and winder, and the metal sheet 5 is placed on the lower mold 401 at the same time. At this time, the limiting plates 603 on both sides are used to support the metal sheet 5 to be stamped. At the same time, the torsion of the torsion shaft 608 causes the pressing roller 609 to press the metal sheet 5, so that the position of the metal sheet 5 placed on the lower mold 401 can be limited. Since the top end of the limiting plate 603 is horizontally aligned with the top of the lower mold 401, the metal sheet 5 can be limited to fit the top surface of the lower mold 401, which is conducive to making the metal sheet 5 placed on the lower mold 401 flush with the lower mold 401, reducing the bending degree of the metal sheet 5, thereby improving the stamping accuracy of the metal sheet 5;

[0038] Before stamping, the distance between the two sets of limiting mechanisms 6 on one side can be adjusted according to the width of the metal sheet 5 by sliding the slide groove 601, thereby improving the applicability of stamping processing for metal sheets 5 of different widths; the limiting plate 603 is rotated by the rotating shaft 604, and then the angular position of the limiting plate 603 is fixed by the tightening handwheel 606. In this way, the installation angle of the limiting plate 603 can be adjusted according to different models and types of lower molds 401, thereby further improving its environmental applicability.

[0039] Parts not involved in the present invention are the same as those in the prior art or can be implemented by using the prior art, and will not be described in detail here.
