Description

Technical Field

[0001] The invention relates to the field of die forging, in particular to a novel hot die forging socket hydraulic die frame. Background Art

[0002] At present, in the field of die forging, die forging is one of the most important links, and the die frame is a necessary basic equipment. Forging die refers to a tool that can form the blank into a die forging. The forging die is a key process equipment necessary for the production of die forgings. It is a tool that needs to be used in every stroke of the equipment and plays a pivotal role in the production of die forgings. The 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, thereby obtaining parts of the required shape and size. Forging dies can be divided into hot forging dies, warm forging dies and cold forging dies according to the different forging temperatures. Hot forging dies can also be divided into hammer forging dies, screw press forging dies, mechanical press forging dies, flat forging dies and hydraulic press forging dies due to different equipment. It is necessary to design and process the die frame during press die forging. In the forging process, blanking dies, trimming dies, punching dies, correction dies, cold precision dies, etc. are also required. These dies and devices also belong to the category of forging dies.

[0003] However, the existing mold frame uses bolts and pressure plates to fix the mold around, and the bolts need to be tightened manually. The installation is complicated and it is easy to cause mold misalignment due to the tightness of the bolts. In addition, the mold itself has a complex structure and many intermediate cavities, which is inconvenient for both processing and maintenance. Therefore, in order to solve such problems, we proposed a new hot die forging socket hydraulic mold frame. Summary of the invention

[0011] The beneficial effects of the present invention are: 1. The mold is placed in the groove in the middle part of the upper and lower bases, and the left, right and back surfaces of the mold are all in contact with the groove surface of the mold base, avoiding large errors between the mold and the mold base due to installation and connection, effectively solving the problem of mold misalignment, and the mold is clamped and fixed by a hydraulic cylinder. The mold installation can be adjusted by adjusting the control button of the hydraulic cylinder, which can achieve rapid mold change and the device is convenient; 2. The mold is fixed by installing the mold in the middle groove of the mold base to simplify the structure of the mold frame base, facilitate processing and maintenance, and the heat treatment hardness of the entire matrix of the mold base is higher, which increases the wear resistance of the mold base and reduces the number of mold base renovations. This function is practical; 3.
