Abstract
Description
Technical Field
[0001] This utility model relates to the field of forging furnace technology, specifically a multi-station rapid mold changing mechanism for forging furnaces. Background Technology
[0002] In the forging industry, forging furnaces are crucial production equipment, widely used in metal forming processes. With the continuous development of manufacturing, production process requirements are becoming increasingly stringent, placing higher demands on the efficiency and precision of forging furnaces. Especially in production environments requiring frequent mold changes, mold-changing operations consume a significant portion of production time, directly impacting production efficiency. Therefore, developing an efficient and rapid mold-changing mechanism is of paramount importance.
[0003] Existing die-changing mechanisms in forging furnaces generally suffer from problems such as complex structure, cumbersome operation, and low efficiency. Traditional die-changing mechanisms typically require manual labor or cumbersome mechanical devices to change the die, a process that often takes a long time and is easily affected by the operator's skill level, leading to errors or delays. Furthermore, traditional die-changing systems are structurally complex and difficult to maintain, increasing production costs and potentially disrupting the production process, thus impacting overall production efficiency.
[0004] Especially in multi-station production environments, each station may require different molds for production. Because existing mold-changing mechanisms cannot achieve quick and accurate mold replacement, the equipment must be stopped for adjustments each time a mold is changed, resulting in excessive downtime on the production line. Furthermore, traditional mold-changing methods often fail to consider the collaborative work between workstations, making it difficult to synchronize mold-changing operations, increasing the burden on operators and the difficulty of production line management.
[0005] Therefore, based on the above-mentioned technical problems, it is necessary for those skilled in the art to develop a multi-station rapid die-changing mechanism for forging furnaces. Utility Model Content

[0026] The features and exemplary embodiments of various aspects of this utility model will now be described in detail. To make the objectives, technical solutions, and advantages of this utility model clearer, the following description, in conjunction with the accompanying drawings and specific embodiments, will provide a further detailed description. For those skilled in the art, this utility model can be implemented without some of these specific details. The following description of the embodiments is merely intended to provide a better understanding of this utility model by illustrating examples.
[0027] like Figure 1 , Figure 2 and Figure 3 As shown, this utility model provides a technical solution for a multi-station rapid die-changing mechanism for a forging furnace: it includes a base 1 on which multiple push cylinders 2 are fixed. The output end of each push cylinder 2 is connected to a push rod 21. The push cylinder 2 can be a multi-stroke cylinder so as to drive the push seat 23 to move along the guide limit rod 22, thereby realizing multi-station switching.
[0028] like Figure 2 As shown, guide limit rods 22 are arranged parallel to both sides of push rod 21 to guide the movement of push rod 21. Push seat 23 is fixedly connected to push rod 21 and guide limit rods 22. Push seat 23 is provided with guide bar opening 231 and positioning insertion hole 232. Guide bar opening 231 is a rectangular groove, and the cross-sectional shape of mold base guide bar 24 matches the guide bar opening 231 to ensure stability during sliding.
[0029] The mold base guide bar 24 is slidably installed in the guide bar opening 231, and the mold base guide bar 24 is provided with a positioning slot 241. The positioning pin 25 cooperates with the positioning slot 241 through the positioning insertion hole 232 to realize the quick positioning and locking of the mold base guide bar 24.
[0030] The mold base 3 is mounted on the mold base guide 24, and the mold base 3 has a mold groove 31 for placing the mold. The mold groove 31 is equipped with a quick clamping device (not shown in the figure) for fixing the workpiece. The quick clamping device can be a pneumatic clamp, a hydraulic clamp, or other types of quick clamping mechanism to enable rapid fixing and release of the workpiece.
[0031] Multiple sets of push cylinders 2 are evenly spaced to accommodate multi-station requirements. This distribution ensures the uniformity and synchronization of the mold changing mechanism when switching between different stations.
[0032] In practical applications, when mold replacement is required, the operator can activate the push cylinder 2. The push rod 21 pushes the push base 23 along the guide limit rod 22, moving the mold base guide bar 24 together with the mold base 3 to the designated station. After reaching the designated station, the positioning pin 25 engages with the positioning slot 241 to achieve rapid positioning and locking of the mold base guide bar 24. At this time, the quick clamping device can quickly clamp or release the workpiece, completing the mold change process.
[0033] Compared with existing technologies, this utility model's multi-station rapid die-changing mechanism for forging furnaces achieves rapid and stable switching of the die holder guide bars through the coordination of multiple sets of pushing cylinders and guide limit rods, significantly shortening die-changing time. Simultaneously, the coordinated design of the positioning pins and positioning slots improves the accuracy and efficiency of die changing. The use of multi-stroke cylinders enhances applicability and flexibility, meeting the needs of different workstations. The matching of the rectangular groove design of the guide bar opening with the cross-sectional shape of the die holder guide bars ensures stability during sliding. The rapid clamping device installed within the die groove further improves production efficiency. This utility model has advantages such as simple structure, convenient operation, high die-changing efficiency, and good accuracy, effectively solving the problems existing in current forging furnace die-changing mechanisms and providing strong technical support for production in the forging industry.
