Description

Technical Field

[0001] This utility model relates to the field of cold heading mold technology, and in particular to a quick assembly and disassembly structure for cold heading mold. Background Technology

[0002] Cold heading is a minimal or no-cutting machining process. Its principle is to use a mold to apply impact or pressure to a metal billet at room temperature, causing the billet to plastically flow within the mold cavity, filling the mold cavity, and ultimately forming a part with a specific shape, size, and performance.

[0003] Cold heading is commonly used in the production of standard parts such as bolts, nuts, and bearings. Due to the high-frequency impact, the molds wear out quickly, and the multi-variety, small-batch production mode requires frequent switching of product specifications. Traditional bolt connection mold changes take too long, while quick disassembly and assembly structures can shorten the time.

[0004] In the existing technology, a quick assembly and disassembly structure for a cold heading die usually requires manual tightening of bolts and adjustment of die position by wrenches, hammers and other tools to install different types of dies. Such frequent die changes will increase die change time and extend downtime, resulting in reduced production efficiency. Utility Model Content

[0005] To overcome the above shortcomings, this utility model provides a quick assembly and disassembly structure for cold heading dies, aiming to solve the problem in the prior art where operators tighten bolts and adjust die positions one by one using tools such as wrenches and hammers, which leads to increased die change time and extended downtime, resulting in reduced production efficiency.

[0006] To achieve the above objectives, the present invention provides the following technical solution:

[0007] A quick-assembly and disassembly structure for a cold heading die includes a guide block, a push rod slidably connected to the inner wall of the guide block, an mounting block slidably connected to the outer wall of the guide block, a hollow block fixedly connected to the inner wall of the mounting block, a locking block slidably connected to the inner wall of the hollow block, a spring fixedly connected to the inner wall of the locking block, a tilting rod slidably connected to the inner wall of the mounting block, a sliding rod slidably connected to the outer wall of the tilting rod, a fixing block fixedly connected to the inner wall of the sliding rod, a second spring fixedly connected to the outer wall of the fixing block, a second spring fixedly connected to the inner wall of the mounting block, and a sliding rod slidably connected to the inner wall of the guide block.

[0009] Preferably, the inner wall of the fixing base is fixedly connected to a mounting column, and the inner wall of the mounting column is provided with a tension spring.

[0010] Preferably, a fixing plate is fixedly connected to the upper surface of the tension spring, and the outer wall of the fixing plate is slidably connected to the inner wall of the mounting column.

[0024] The technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. 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 skilled in the art without creative effort are within the protection scope of this utility model.

[0025] Reference Figures 1-3This utility model provides an embodiment of a quick-assembly and disassembly structure for a cold heading mold, comprising a guide block 1, a push rod 2 slidably connected to the inner wall of the guide block 1, an mounting block 3 slidably connected to the outer wall of the guide block 1, a hollow block 4 fixedly connected to the inner wall of the mounting block 3, a locking block 6 slidably connected to the inner wall of the hollow block 4, a spring 5 fixedly connected to the inner wall of the locking block 6, and the outer wall of the locking block 6 slidably connected to the inner wall of the push rod 2. An inclined rod 7 slidably connects to the inner wall of the mounting block 3, and the outer wall of the inclined rod 7 slidably connects to the inner wall of the guide block 1. A sliding rod 8 slidably connects to the outer wall of the inclined rod 7, a fixing block 9 fixedly connected to the inner wall of the sliding rod 8, and a spring 10 fixedly connected to the outer wall of the fixing block 9. The outer wall of the spring 10 is fixedly connected to the inner wall of the mounting block 3. A sliding connection is made to the inner wall of the guide block 1. An installation component is provided on the lower surface of the guide block 1. The installation component includes a first mold 11. The upper surface of the first mold 11 is fixedly connected to the lower surface of the guide block 1. A turntable 12 is rotatably connected to the inner wall of the first mold 11. A guide plate 13 is detachably installed on the outer wall of the turntable 12. A centering block 14 is slidably connected to the inner wall of the guide plate 13. A second mold 15 is snapped onto the outer wall of the first mold 11. The upper surface of the second mold 15 is fixedly connected to the lower surface of the installation block 3. A bolt 16 is threadedly connected to the inner wall of the second mold 15. The outer wall of the bolt 16 is slidably connected to the outer wall of the centering block 14. A fixing seat 17 is detachably installed on the outer wall of the first mold 11. The inner wall of the fixing seat 17 is detachably installed on the outer wall of the second mold 15.

[0026] Specifically, by installing the guide plate 13 onto the outer wall of the turntable 12 and the centering block 14 onto the inner wall of the guide plate 13, and by installing the second mold 15 onto the outer wall of the first mold 11, the first mold 11 drives the push rod 2 to install onto the inner wall of the mounting block 3. The mounting block 3 is fixed to the upper surface of the second mold 15, enabling the second mold 15 to achieve a quick installation effect. The guide block 1 slides on the outer wall of the locking block 6, and the locking block 6 slides on the inner wall of the hollow block 4, which is fixed to the inner wall of the mounting block 3. This allows the guide block 1 to slide to the appropriate position, after which the spring 5 pushes the locking block 6 to lock the guide block 1, achieving a self-locking effect. At the same time, the guide block 1 pushes the tilting rod 7 to slide on the inner wall of the mounting block 3, causing the tilting rod 7 to push the sliding rod 8. The sliding mechanism, where the slide rod 8 locks against the outer wall of the guide block 1, compresses the spring 10, providing power for the slide rod 8 to reset. Pushing the push rod 2 will push the slide rod 8 and the locking block 6 to slide synchronously, achieving a quick release of the self-locking effect. By rotating the bolt 16 on the inner wall of the second mold 15 to abut against the centering block 14, the bolt 16 drives the centering block 14 to slide, achieving a quick centering and clamping effect for mold cores of different sizes. After the centering block 14 fixes the mold core, the first mold 11 and the second mold 15 are placed on the inner wall of the fixed seat 17, and the mold core passes through the fixed seat 17, achieving a quick installation effect. The first mold 11 can be quickly installed and disassembled for cold heading molds, shortening mold changing and downtime, thereby improving production efficiency.

[0027] Reference Figure 1 and Figure 4 The inner wall of the fixed base 17 is fixedly connected to the mounting column 18, the inner wall of the mounting column 18 is provided with a tension spring 19, the upper surface of the tension spring 19 is fixedly connected to the fixed plate 20, the outer wall of the fixed plate 20 is slidably connected to the inner wall of the mounting column 18, the inner wall of the fixed plate 20 is fixedly connected to the rotating column 21, the outer wall of the rotating column 21 is slidably connected to the inner wall of the fixed base 17, and the outer wall of the rotating column 21 is slidably connected to the inner wall of the mounting column 18.

[0028] Specifically, by installing the mounting post 18 onto the inner wall of the fixing base 17, the tension spring 19 fixed to the inner wall of the mounting post 18 pulls the fixing plate 20 to slide on the inner wall of the mounting post 18. The fixing plate 20 will drive the rotating post 21 to slide on the inner wall of the mounting post 18, so that the fixing plate 20 and the rotating post 21 can achieve the effect of stable sliding on the inner wall of the mounting post 18. By pulling the rotating post 21 to slide on the inner wall of the fixing base 17, the tension spring 19 will pull the fixing plate 20 after the rotating post 21 drives the fixing plate 20 to slide to the appropriate position, which can achieve the effect of self-locking. After the fixing plate 20 slides to the appropriate position, the mounting post 18 will abut against the fixing plate 20, which can achieve the effect of stable support for the rotating post 21.

[0029] Reference Figure 4A handle 22 is fixedly connected to the outer wall of the rotating column 21. A support block 23 is rotatably connected to the outer wall of the rotating column 21. A gear 24 is rotatably connected to the inner wall of the support block 23. A pressing rod 25 is fixedly connected to the outer wall of the gear 24. The outer wall of the pressing rod 25 is rotatably connected to the inner wall of the fixed seat 17. A pressing plate 26 is fixedly connected to the outer wall of the pressing rod 25. The lower surface of the pressing plate 26 is slidably connected to the upper surface of the centering block 14.

[0030] Specifically, pulling or rotating the handle 22 will cause the rotating column 21 to move synchronously, achieving a stable adjustment effect. The rotating column 21 drives the support block 23 to slide, causing the gear 24 on the inner wall of the support block 23 to rotate synchronously, and the gears 24 on both sides mesh with each other, enabling the pressing rods 25 on both sides to rotate synchronously. The pressing rod 25 rotates on the inner wall of the fixed base 17, causing the pressing rod 25 to drive the pressing plate 26 to rotate synchronously, enabling the pressing plate 26 to quickly fix the first mold 11 and the second mold 15. The pressing rod 25 can be used to quickly remove the mold by pushing, pulling and rotating, achieving precise mold positioning while reducing the difficulty of operation.

[0031] Working principle: When this structure is needed, pulling and turning handle 22 when the cold heading die needs to be changed will cause the support block 23, rotating column 21 and fixed plate 20 to slide synchronously. When the fixed plate 20 rotates to the appropriate position, the tension spring 19 fixed to the inner wall of the mounting column 18 will pull the fixed plate 20 to slide on the inner wall of the mounting column 18, which can achieve the effect of quick adjustment of the support block 23. Pulling the pressing rod 25 will cause the pressing plate 26 to rotate synchronously on the inner wall of the fixed seat 17. The pressing rod 25 rotates on the inner wall of the support block 23, which can cause the pressing rod 25 to drive the gear 24 to rotate synchronously, so that the pressing rods 25 on both sides rotate synchronously. When the pressing plate 26 disengages from the centering block 14 and the first die 11 and the second die 15 are removed, pressing the push rod 2 sliding on the inner wall of the guide block 1 will push the locking block 6 to slide on the inner wall of the hollow block 4 and compress the spring 5 to achieve quick release of the self-locking mechanism. The effect of this structure is that pulling the guide block 1 away from the mounting block 3 and the tilting rod 7 causes the spring 10 to push the fixing block 9 back to its original position while simultaneously driving the sliding rod 8 to slide synchronously. This allows the sliding rod 8 to quickly release its self-locking effect on the guide block 1. By pushing the tilting rod 7 to slide on the inner wall of the mounting block 3, the tilting rod 7 can quickly return to its original position. By removing the second mold 15, the bolt 16 can simultaneously disengage from the centering block 14, achieving the effect of quick assembly and disassembly of the mold core. By installing the guide plate 13 onto the outer wall of the turntable 12, and the turntable 12 rotating on the inner wall of the first mold 11, a stable rotation effect can be achieved. This structure not only enables quick assembly and disassembly of cold heading molds, shortening mold change and downtime, thereby improving production efficiency, but also allows for quick removal of molds by pushing, pulling, and rotating, achieving precise mold positioning while reducing operational difficulty.
