Description

A fine-tuning and positioning device for precision forming molds

technical field

The utility model relates to a fine-tuning and positioning device, in particular to a fine-tuning and positioning device applied to precision-formed punch or die inserts.

Background technique

IT product parts generally have the characteristics of ultra-thin material thickness (material thickness below the millimeter level), complex appearance and small size, very high shape and position accuracy (dimensional accuracy is required to be close to the micron level), and huge production batches. Therefore, Precision progressive dies are usually used for precision forming. The precision progressive die can complete various stamping processes such as punching, bending, shaping, and embossing on a pair of dies. There can be dozens of stations, and it is generally assembled from hundreds of parts. For each station of stamping and forming, there must be corresponding forming punches and die inserts. The punches and die inserts are not only responsible for direct forming, but also determine the shape, size and size of the workpiece on the mold. The most critical part of precision. Due to the ultra-thin material thickness of IT product parts and very high dimensional accuracy and shape and position tolerance requirements, various processes such as embossing, bending, deformation adjustment, etc. require precision forming The height of the punch or die insert must retain a certain relative size , adjust with the fine-tuning positioning device. At present, the commonly used positioning adjustment device is composed of a wedge, an adjustment rod, an adjustment screw, a pressure plate, and a fastening screw. The height adjustment of the punch or die insert can be realized under the action of the punch. When adjusting, it is necessary to remove the pressing plate first, screw in or unscrew the adjusting screw, and then install the pressing plate to fix it, which is cumbersome to operate. Moreover, for the forming of some ultra-thin material parts (material thickness t is less than or equal to 0.1mm), such as the embossing process, the adjustment requirement is very small, and it is difficult to meet the process requirements only by adjusting the adjustment screw, and the stability of the device is poor. Therefore, An adjustment device with higher precision is required to meet the needs of precision production. In addition, there are many adjustment device parts in the commonly used mold forming parts, which is not conducive to the standardization of mold design and manufacture.

(2) The adjusting rod in the fine-tuning positioning device of the precision forming mold of the utility model replaces the wedge, adjusting rod and pressing plate parts in the commonly used adjusting device at present, reducing the number of parts, The structure of the device is simplified, and the assembly time is saved. Moreover, by setting two or more screws arranged vertically up and down at one end of the adjusting rod to fix the adjusting rod on the fixed plate, the parts of the adjusting rod are simple in shape and easy to process, and can achieve a better adjustment effect.
