Description

Technical Field

[0001] This utility model relates to the technical field of integrated punching and slitting mechanisms, specifically, to an integrated punching and slitting mechanism. Background Technology

[0002] Punch presses, as a common processing equipment, are widely used in sheet metal, hardware, automotive, and electronics industries to complete forming processes such as punching, blanking, bending, and stretching. In the production and processing of sheet or strip materials, punching and slitting are two extremely common and continuous production needs.

[0003] In existing technologies, stamping and slitting are typically accomplished using two separate, independent pieces of equipment. A typical production process involves first slitting the material longitudinally using a high-speed slitting machine to obtain multiple semi-finished products of the required width; then, these slitted semi-finished products are transported to another independent stamping press for forming. Alternatively, the material can be stamped first, followed by slitting.

[0004] This traditional separate production method, although technically mature, requires separate loading, unloading, positioning and other related devices, which results in higher costs, increased equipment space occupation, and low production efficiency. Utility Model Content

[0035] The technical solutions of this utility model will be clearly and completely described below with reference to the embodiments of this utility model. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of this utility model.

[0036] like Figures 1 to 10 As shown, an integrated punching and slitting mechanism is mainly used in a punch press 1. It includes an upper die holder 2 fixedly connected to the slide of the punch press 1, used to install upper templates 3 for processing corresponding products and processes (such as for slitting or punching); and a lower die holder 7 installed on the worktable of the punch press 1, used to install punching templates 5 or steel dies 6 (i.e., lower dies for slitting). The punching template 5 is mainly used for product punching, and the steel die 6 is used for product slitting. In this embodiment, the punching template 5 or steel die 6 for the relevant product can be independently installed on the lower die holder 7. The attached diagram is for illustrative purposes only; in practice, the corresponding die can be replaced according to the specific product. The upper die holder 2 is also equipped with guide pillars 4, which pass through the upper die holder 2 and slide in cooperation with it, further improving the accuracy of the upper die holder 2 and lower die holder 7 during die closing and improving production quality.

[0037] Because integrated slitting and stamping is a highly efficient process, it places extremely high demands on design and manufacturing, requiring stable and reliable mold switching conditions. Therefore, in this embodiment, two sets of upper mold guide grooves 21 are installed on the upper mold frame 2 to assist in the positioning and installation of the upper template 3, and two sets of upper mold baffles 22 are fixedly connected to the upper mold guide grooves 21. This, in conjunction with the upper mold frame 2, ensures precise positioning of the upper template 3 during installation, reducing deviations. By embedding the opposite sides of the upper template 3 into the upper mold guide grooves 21, the two degrees of freedom of the upper template 3 in two directions are first defined. Then, the two sets of upper mold baffles 22 are installed on both sides of the upper template 3, further defining the two degrees of freedom in two directions. The remaining two degrees of freedom are defined by the inner walls of the upper mold frame 2 and the upper mold guide grooves 21. The upper mold baffles 22 are fitted into the upper mold guide grooves 21 and then installed and fixed with fasteners, which is convenient for installation, easy for positioning, and highly accurate.

[0038] Similarly, in this embodiment, two sets of lower mold guide grooves 71 are provided on the lower mold frame 7, and the opposite sides of the stamping template 5 or steel die 6 are respectively embedded in the lower mold guide grooves 71. Since the side of the lower mold frame 7 also needs to be provided with functional structures such as side air blowing structure and observation window, this embodiment preferably provides a precision positioning structure between the steel die 6 and the lower mold guide groove 71, which facilitates high-precision installation of the steel die 6 and makes it easy for the steel die 6 or stamping template 5 to be aligned with the upper template 3.

[0039] The lower mold guide groove 71 and the upper mold channel are both L-shaped mechanisms, which can cooperate with the lower mold frame 7 and the upper mold frame 2 to restrict at least 3 degrees of freedom. They can also be used as slides for easy assembly.

[0040] Specifically, the aforementioned precise positioning structure includes a positioning protrusion 72 located inside the lower mold guide groove 71. Preferably, the positioning protrusion 72 is a triangular prism shape, guided by two angled sides. After positioning and installation in the lower mold guide groove 71, it can be more easily embedded into the side of the steel die 6 or the punching template 5 (as shown in the attached diagram, the side of the steel die 6 has a positioning groove 61) to complete the positioning. The lower mold guide groove 71 has several slotted holes, which are fixedly connected to the lower mold frame 7 by fasteners. After pre-tightening, the installation position can be finely adjusted using the slotted holes to ensure positioning accuracy. To facilitate observation of the assembly of the lower mold guide groove 71 and the steel die 6, an observation port 73 is also provided on the upper part of the positioning protrusion 72 in the lower mold guide groove 71.

[0041] During the stamping or slitting process, waste and debris are generated, especially during stamping, where the waste needs to be directly punched to the lower die holder 7. If it remains on the worktable or die of the press 1, it will affect the subsequent production and processing. Therefore, this embodiment provides an air blowing device and a side air blowing structure on one side of the lower die holder 7. Specifically, the air blowing device includes a magnetic base 81, a turning plate 84, a limiting plate 85, and a magnet 82. The magnet 82 is fixed to the magnetic base 81 with fasteners, which allows the magnetic base 81 to be magnetically attached to the part of the lower die holder 7, the steel die 6, or the lower die closest to the part that needs air blowing, depending on the die conditions. The limiting plate 85 is located above the magnet 82 and has an "L"-shaped structure, which facilitates bidirectional positioning during installation and ensures structural stability. The upper air-blowing box 86 is connected to the top of the steering plate 84 through an arc-shaped steering hole. The upper air-blowing box 86 has a hollow structure and a strip-shaped air-blowing hole 87 on one side. By connecting a high-pressure air pipe, high-pressure air is introduced into the upper air-blowing box 86 and then blown from the air-blowing hole onto the surface of the product or mold to clean up waste. The strip-shaped air outlet structure of the air-blowing hole can guide and improve the coverage area of ​​the air blowing, while maintaining the air pressure to ensure the cleaning effect.

[0042] In addition, the side-blowing air structure is mainly used to blow away waste and debris that fall into the lower mold frame 7, so it is installed on the opening side of the lower mold frame 7. The main structure includes a side-blowing air seat 91 and a side-blowing air pressure plate 92. A ventilation groove 93 is opened on the side of the side-blowing air seat 91 facing the lower mold frame 7 for air outlet. The side-blowing air pressure plate 92 covers the ventilation groove 93 and has a strip-shaped air outlet 87 on one side of the side-blowing air groove (this structure is the same as the upper air box 86 in principle). High-pressure air is introduced into the side-blowing air seat 91 by connecting a high-pressure air pipe and exits from the strip-shaped air outlet 87 at the side-blowing air pressure plate 92.

[0043] On the other side of the lower mold frame 7, several magnetic plates 78 in an "L" shape can be set, and magnets 82 are set at their bottom to magnetically attach to the lower mold frame 7. These can be used to temporarily fix baffles, observation glass plates, etc., to improve the flexibility of equipment use.

[0044] Because some products are much larger than the steel die 6 or die template 5 during the stamping or slitting process, additional support plates are used to support the product around its perimeter to ensure stable placement. In this embodiment, several magnetic seats are placed on both sides of the lower die frame 7, i.e., on the worktable of the punch press 1. Each magnetic seat is magnetically attracted to the worktable of the punch press 1 by a magnet 82, which facilitates disassembly and assembly and improves production efficiency.

[0045] The magnetic base has a specific structure consisting of a lower magnetic base 74, an upper magnetic support 75, and a magnetic support block 76. The magnetic support block 76, also known as a magnet 82, is used to magnetically attract the support plate. It is easy to assemble and disassemble and is flexible in use. It is embedded in the upper magnetic support. The lower magnetic base 74 also has a magnet 82 embedded in its bottom. In order to facilitate height adjustment and adapt to different steel die dies 6 and stamping templates 5, a height adjustment rod 751 is provided on the downward side of the upper magnetic support 75, and a height adjustment groove 741 is opened on the upper part of the lower magnetic base 74. The height adjustment rod 751 is embedded in the height adjustment groove 741 and slides in fit. Then, several height positioning holes 742 are opened vertically on the side of the lower magnetic base 74. After the height of the upper magnetic support 75 is adjusted, a positioning screw 77 with a knob is inserted into one of the height positioning holes 742. The end of the positioning screw 77 is pressed against the side wall of the height adjustment rod 751 by a threaded connection to achieve fixation.

[0046] Electronic products, such as FPCs, are relatively sensitive to static electricity, and the high-speed tearing, friction, and extrusion during the stamping or slitting process can generate a large amount of static electricity. Therefore, in order to protect the product, this embodiment additionally provides an ion fan 11 on one side of the upper die frame 2 to eliminate static electricity during stamping and slitting. The ion fan 11 is fixedly connected to the upper die frame 2 or the external punch press 1 through a fan bracket 12.

[0047] The above are merely preferred embodiments of the present utility model and are not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model shall be included within the protection scope of the present utility model.
