Description

Technical Field

[0001] This utility model specifically relates to a cold-pressed mushroom head mechanism for hardware parts, belonging to the field of hardware parts. Background Technology

[0002] The cold-pressed mushroom head mechanism of hardware usually refers to a component with a specific shape and function that is formed by cold working process (i.e., without heating at room temperature or near room temperature).

[0003] Existing cold-pressing mushroom head mechanisms for hardware play a crucial role in industrial production, especially in manufacturing processes requiring precision forming. These mechanisms typically secure the forming mold with bolts to ensure that the mold does not shift or loosen during high-pressure cold pressing operations, thereby guaranteeing that the quality and specifications of the finished product meet expected standards. However, while this method of securing the mold provides the necessary stability, it also presents several challenges.

[0004] First, with frequent changes to the forming mold, the disassembly and installation process becomes particularly cumbersome. Each replacement requires workers to unscrew multiple bolts one by one and then retighten them when installing the new mold, which is not only time-consuming but also inefficient. Furthermore, due to repeated disassembly and assembly, the bolts and their corresponding bolt holes are prone to wear, leading to a gradual weakening of the fixing effect. Over time, the bolts may fail to provide the clamping force originally designed, increasing the risk of mold displacement during use, thus affecting product quality and potentially leading to defective products, reducing the overall product yield. More seriously, as wear intensifies, it may cause safety hazards. For example, a loose mold suddenly shifting during cold pressing could damage machinery or, worse, cause personal injury. Therefore, finding a solution that allows for quick mold replacement while ensuring its stability and safety is crucial. Utility Model Content

[0005] The purpose of this utility model is to address the shortcomings of the existing technology by providing a cold-pressing mushroom head mechanism for hardware parts.

[0006] This utility model achieves the above-mentioned objective through the following technical solution: a cold-pressed mushroom head mechanism for hardware, including an installation cabinet, a detachable molded template connected to the top of the installation cabinet, an extrusion assembly matching the molded template detachably connected to the upper surface of the installation cabinet, multiple fixed columns fixedly connected to the bottom of the molded template, the multiple fixed columns being inserted into the installation cabinet, a plug-in rod rotatably connected inside the installation cabinet, the plug-in rod passing through the multiple fixed columns, and a limiting assembly for limiting the plug-in rod being movably connected inside the installation housing.

[0007] Preferably, the limiting component includes a fixing block with a through hole matching the plug rod. A movable rod is inserted through one side of the mounting shell, with one end of the movable rod inserted into the through hole and the other end passing through the outer wall of the mounting shell. A receiving plate is fixedly connected to the outside of the movable rod, and a limiting plate is nested outside the movable rod. The limiting plate is threaded to the outer wall of the mounting shell, and an elastic element is provided between the limiting plate and the receiving plate.

[0008] Preferably, the extrusion assembly includes a lifting plate located above the mounting shell. Multiple guide columns are inserted inside the lifting plate. The bottom ends of the multiple guide columns are bolted to the upper end face of the mounting shell, and the top ends of the multiple guide columns are fixedly connected to the top plate. A drive component for driving the lifting plate to move up and down is inserted inside the top plate.

[0009] Preferably, the driving component includes a hydraulic cylinder, which is bolted to the top plate and the bottom end of the hydraulic cylinder is bolted to the upper surface of the lifting plate.

[0010] Preferably, the bottom end of the lifting plate is detachably connected to an extrusion template that matches the shaping template, and the extrusion template is located directly above the shaping template.

[0011] Preferably, the plug rod includes a drive shaft, one end of which passes through the side wall of the mounting housing, and the other end of which is rotatably connected to the inner side wall of the mounting housing. An arc-shaped rod is fixedly connected to the outside of the drive shaft.

[0012] Preferably, the multiple fixed posts have slots that match the arc-shaped rod.

[0013] The beneficial effects of this utility model are:

[0014] 1. The design of using plug-in rods to limit the positioning of the template greatly simplifies the template fixing process. Compared with the traditional bolt fixing method, there is no need to tighten or loosen multiple bolts one by one. The initial fixing can be completed simply by inserting the plug-in rod into the preset position. This method is not only easy to operate, but also greatly shortens the time required for each replacement, effectively improving production efficiency.

[0015] 2. By further limiting the insertion rod with the limiting component, it can be prevented from moving freely due to external force during use, ensuring that the shaping template remains highly stable throughout the cold pressing process. This dual protection mechanism effectively avoids mold displacement problems caused by insecure fixing, thereby reducing the possibility of producing defective products and improving the product qualification rate.

[0016] 3. The design of this mechanism includes the function of removing the limiting position of the template by pulling the movable rod and then rotating the plug rod. This makes the disassembly of the template simple and quick. Workers do not need to use extra tools and can easily replace the template in just a few simple steps, which greatly facilitates maintenance and adjustment. This design not only saves labor costs, but also reduces the risk of wear and tear caused by repeated disassembly and assembly, and extends the service life of the equipment.

Detailed Implementation

[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0025] Please see Figures 1-6As shown, a cold-pressed mushroom head mechanism for hardware includes an installation cabinet 1. A shaping template 2 is detachably connected to the top of the installation cabinet 1. An extrusion assembly 3 matching the shaping template 2 is detachably connected to the upper surface of the installation cabinet 1. Multiple fixing posts 4 are fixedly connected to the bottom of the shaping template 2. The multiple fixing posts 4 are inserted into the installation cabinet 1. A plug-in rod 5 is rotatably connected inside the installation cabinet 1. The plug-in rod 5 passes through the multiple fixing posts 4. A limiting assembly 6 for limiting the plug-in rod 5 is movably connected inside the installation housing.

[0026] It should be noted that when installing the template 2, firstly, the fixing post 4 at the bottom of the template 2 is inserted into the installation cabinet 1 from the top of the installation cabinet 1. Then, the plug rod 5 is rotated so that the plug rod 5 passes through multiple fixing posts 4 in sequence, thereby limiting the multiple fixing posts 4 and thus limiting the template 2. At the same time, the plug rod 5 is rotated further so that the limiting component 6 limits the plug rod 5, thereby preventing the plug rod 5 from moving freely and losing its limiting effect on the multiple fixing posts 4.

[0027] The limiting component 6 includes a fixing block 61, which has a through hole 62 that matches the plug-in rod 5. A movable rod 63 is inserted through one side of the mounting shell. One end of the movable rod 63 is inserted into the through hole 62, and the other end of the movable rod 63 passes through the outer wall of the mounting shell. A receiving plate 64 is fixedly connected to the outside of the movable rod 63. A limiting plate 65 is also nested outside the movable rod 63. The limiting plate 65 is threaded to the outer wall of the mounting shell. An elastic element 66 is provided between the limiting plate 65 and the receiving plate 64.

[0028] It should be noted that the plug rod 5 includes a drive shaft 51, one end of which passes through the side wall of the mounting housing, and the other end of which is rotatably connected to the inner side wall of the mounting housing. An arc-shaped rod 52 is fixedly connected to the outside of the drive shaft 51, and an insertion hole matching the movable rod 63 is opened in the arc-shaped rod 52.

[0029] The side wall of the movable rod 63 adjacent to the plug rod 5 is an inclined side wall. When the plug rod 5 is inserted into the through hole 62, the plug rod 5 applies a pressing force perpendicular to the inclined side wall of the movable rod 63. Under the limitation of the movable rod 63 by the mounting cabinet 1, the movable rod 63 slides to the outside of the mounting cabinet 1. At the same time, the receiving plate 64 presses the elastic element 66 until the movable rod 63 is inserted into the insertion hole of the arc rod 52 under the action of the elastic potential energy of the elastic element 66.

[0030] When it is necessary to replace the template 2, first pull the movable rod 63. The movable rod 63 applies a force to the elastic element 66, compressing the elastic element 66 and pulling the movable rod 63 out of the insertion hole of the arc rod 52. At this time, rotate the drive shaft 51, which drives the arc rod 52 to rotate, pulling the arc rod 52 out of the multiple fixed posts 4. Then the template 2 can be pulled out and replaced.

[0031] The extrusion assembly 3 includes a lifting plate 31, which is located above the mounting shell. Multiple guide posts 32 are inserted inside the lifting plate 31. The bottom ends of the multiple guide posts 32 are bolted to the upper end face of the mounting shell, and the top ends of the multiple guide posts 32 are fixedly connected to the top plate 33. A driving component for driving the lifting plate 31 to rise and fall is inserted inside the top plate 33.

[0032] It should be noted that the bottom end of the lifting plate 31 is detachably connected to an extrusion plate 35 that matches the shaping plate 2, and the extrusion plate 35 is located directly above the shaping plate 2;

[0033] The lifting plate 31 is driven to descend by the driving component, so that the lifting plate 31 drives the extrusion template 35 to dock with the shaping template 2, thereby extruding and shaping the hardware.

[0034] The driving component includes a hydraulic cylinder 34, which is bolted to the top plate 33, and the bottom end of the hydraulic cylinder 34 is bolted to the upper end face of the lifting plate 31.

[0035] Multiple fixed posts 4 have slots 7 that match the arc-shaped rod 52.

[0036] Working principle: When installing the template 2, firstly, the fixed column 4 at the bottom of the template 2 is inserted into the installation cabinet 1 from the top of the installation cabinet 1. Then, the plug rod 5 is rotated so that the plug rod 5 passes through multiple fixed columns 4 in sequence, thereby limiting the multiple fixed columns 4 and thus limiting the template 2. At the same time, the plug rod 5 is rotated again so that it is inserted into the through hole 62. The plug rod 5 applies a pressing force perpendicular to the inclined side wall of the movable rod 63. Under the limitation of the movable rod 63 by the installation cabinet 1, the movable rod 63 slides outward from the installation cabinet 1. At the same time, the receiving plate 64 presses the elastic element 66 until the movable rod 63 is inserted into the insertion hole of the arc rod 52 under the action of the elastic potential energy of the elastic element 66, thereby limiting the arc rod 52 by the limiting component 6.

[0037] When it is necessary to replace the template 2, first pull the movable rod 63. The movable rod 63 applies a force to the elastic element 66, compressing the elastic element 66 and pulling the movable rod 63 out of the insertion hole of the arc rod 52. At this time, rotate the drive shaft 51, which drives the arc rod 52 to rotate, pulling the arc rod 52 out of the multiple fixed posts 4. Then the template 2 can be pulled out and replaced.
