Description
Technical Field
[0001] The utility model belongs to the technical field of forging dies, and particularly relates to a forging die for a wind power gear forging. Background Technique
[0002] When the upper die holder and the lower die holder are respectively installed on the upper template and the lower template, they cannot play a role in limiting and fixing, nor can the upper die holder and the lower die holder be stably and accurately fixed on the upper template and the lower template, which easily causes displacement during the installation of the upper die holder and the lower die holder, affecting the quality of the finished gear forging. A forging die is a die used in the forging process. The raw material undergoes plastic deformation in the forging die under the action of external force to obtain a part with the required shape and size.
[0003] When the forging column and the matching die are respectively installed on the upper template and the lower template, they cannot play a role in limiting and fixing, nor can the matching die and the forging column be stably and accurately fixed on the forging column and the matching die, which easily causes displacement during the installation of the matching die and the forging column, affecting the quality of the finished gear forging. Subsequently, we proposed a forging die for a wind power gear forging. Summary of the Utility Model
[0004] The purpose of the utility model is to provide a forging die for a wind power gear forging. By setting a limiting rod, specifically, the gear to be forged is placed at the center of the matching die, and the forging column is matched with the matching die, thereby avoiding the offset of the die during the forging process. At the same time, the limiting rod arranged at the bottom of the pressing plate cooperates with the spring to assist forging every time the forging is pressed down, ensuring a stable state during the forging process. At the same time, it can also avoid excessive pressure of the second electric push rod during forging, thereby damaging the instrument, and solving the problem that when the forging column and the matching die are respectively installed on the upper template and the lower template, they cannot play a role in limiting and fixing, nor can the matching die and the forging column be stably and accurately fixed on the forging column and the matching die, which easily causes displacement during the installation of the matching die and the forging column, affecting the quality of the finished gear forging.
[0005] To solve the above technical problems, the utility model is realized through the following technical solutions:
[0006] The utility model relates to a forging die for a wind power generation gear forging, which comprises a bearing platform. Four corners of the bottom of the bearing platform are fixedly connected with supporting legs. An electric push rod I is arranged at the center below the bearing platform.

[0011] Furthermore, reserved slots are provided on both the left and right sides of the top of the bearing platform, and a gear slot is provided at the center of the top of the bearing platform. A bearing table is fixedly connected to the top of the first push rod. Specifically, by setting the first push rod, the electric push rod one is started to push the bearing table upward through the first push rod, pushing the bearing table towards the top of the bearing platform, and then the nut two is tightened. Then, the electric push rod one is started again, driving the first push rod to move downward, and driving the bearing table and the adapter mold to move downward together, facilitating the assembly of the adapter mold and also playing a role in assisting demolding after forging, thereby improving production efficiency.
[0012] Furthermore, an adapter mold is slidably connected to the top of the bearing table. An assembly rod two is provided on the right side of the bearing table. The left side of the assembly rod two penetrates the bearing table and extends to the outside. The left side of the assembly rod two penetrates the adapter mold and extends to the outside.

[0014] By setting the limit rod in the utility model, specifically, the raw material to be forged is placed at the center of the adapter mold, and the forging column is adapted to the adapter mold, thus avoiding the offset of the mold during the forging process. At the same time, the spring provided at the bottom of the pressing plate cooperates with the limit rod to press the mold downward smoothly, avoiding offset during the pressing process, thereby ensuring the normal operation of the equipment and reducing the excessive pressure of the electric push rod two during forging, which may damage the instrument.
[0015] By setting the first push rod in the utility model, specifically, the electric push rod one is started to push the bearing table upward through the first push rod, pushing the bearing table towards the top of the bearing platform, and then the nut two is tightened.

[0030] The parts connected by the two limiting rods 323 are the same. The top of the limiting rod 323 on the left side is fixedly connected to the bottom of the pressing plate 32.
