A tool head for incremental forming that can be used in both directions

Abstract

The invention relates to the technical field of molding shaping and specifically relates to a bidirectional usable tool head for asymptotic shaping. The tool head is mainly composed of a bidirectional shaping head (1), a rotating shaft (2), a turning-stopping bolt (3), a locking nut (4), a base plate (5), a protecting outer cover (6) and a shaping head support (7), wherein the turning-stopping bolt (3) and the locking nut (4) are used for controlling the rotating of the bidirectional shaping head (1); the shaping head support (7) is designed into the shape in matching contact with any end of the bidirectional shaping head; and the shaping head support (7) is mainly used for supplying a shaping pressure to the bidirectional shaping head (1) during a shaping process and ensuring the stable state of the bidirectional shaping head (1) during the shaping process. During the asymptotic shaping process, the diameter magnitudes of the shaping tool head required by different shaping areas are different according to the shape feature of parts. According to the invention, the traditional complex step of exchanging the shaping tool head is omitted, and a large-diameter shaping tool head and a small-diameter shaping tool head can be randomly switched through a simple step.

Description

technical field [0001] The patent of the present invention relates to a device in the technical field of shaping and forming, in particular to an improvement of a progressive forming tool head for sheet metal. Background technique [0002] Sheet metal forming has always occupied a very important position in the manufacturing industry, and has been widely used in aerospace, shipbuilding, automobile and construction machinery and other fields. Traditional plate forming requires a press and matching molds. The design and manufacturing costs are high, the flexibility is low, and the cycle is long. Mold forming is only suitable for mass production, and there are limitations in material applicability, making it difficult to meet the needs of small batches, multiple varieties and customization. . At the same time, in order to meet the requirements of light weight, integrated structure and integrated structure and function in various industrial fields today, high-performance alloy ...

AI Technical Summary

Problems solved by technology

Due to the complexity of manufacturing parts in today's manufacturing industry, forming tool heads with different diameters are required for different regions of the part during the gradual forming process. The existing technology is to remove the original tool when the tool head needs to be replaced It is relatively primitive and cumbersome to install the required tool head after the head. If forming a part with complex areas, it is necessary to constantly replace the forming head to ensure high-quality forming.

Through literature search to prior art, it is found that there are relatively few inventions and improvements related to progressive forming tool head. The current situation that the forming head is easy to leave scratches on the processed sheet when it is nearly formed, and to improve the forming effect of the sheet, its invention is limited to a forming tool head with a diameter. Due to its manufacturing cost and installation precision, it is not necessary Applicable to the manufacture of tool heads of various diameters
