Fine blanking machine upper die with adjusting device

Abstract

The invention relates to a fine blanking machine upper die with an adjusting device. The fine blanking machine upper die comprises an upper die body. The upper die body comprises an upper die plate and an upper die device. The upper die adjusting device is arranged in a manner of being connected with the upper die plate and comprises an upper die lifting device and an upper die balance locking device. The upper die lifting device comprises a nut sleeve in threaded connection with the outer wall of the upper die plate. A gear disc is fixedly connected with the nut sleeve. A small gear is in engaged connection with the gear disc. The small gear is mounted at the output end of a downwards-arranged lifting drive motor connected with the top of a fine blanking machine body. The upper die balance locking device comprises a balance locking oil cylinder mounted at the top of the fine blanking machine body, the balance locking oil cylinder is arranged downwards, and a piston rod of the balancelocking oil cylinder is fixedly connected with the center portion of the upper die plate. The fine blanking machine upper die is simple and practical in structure improvement, adjusting operation is convenient, the machining precision is guaranteed, and the good actual use and popularization value is achieved.

Description

technical field [0001] The invention relates to the technical field of stamping machinery and equipment, in particular to an upper mold of a fine blanking machine with an adjustment device. Background technique [0002] With the development of production technology, the shape of fine blanking parts is becoming more and more complex. The fine blanking composite process has become the development and extension of the fine blanking process. However, when the plate is composite fine blanked, the life of the mold is usually low, and the mechanical structure and process parameters need to be optimized. To improve the life of the die; the upper die of the traditional fine blanking machine is fixed, and the lower die moves upward under the drive of the slider to realize the stamping process. For different workpieces, since the heights of different workpieces are not the same, it is obviously impossible to meet the machining accuracy requirements simply by moving the lower die. There...

For different workpieces, since the heights of different workpieces are not the same, it is obviously impossible to meet the machining accuracy requirements simply by moving the lower die. Therefore, in the development process of fine blanking machine tools, improving its structure to improve machining accuracy has become inevitable
