Clamping hoop curved tooling and clamping hoop U-shaped forming mold

Abstract

The invention provides a clamping hoop curved tooling and a clamping hoop U-shaped forming mold. The U-shaped forming mold comprises a second upper pressing mold and a second lower pressing mold; the second lower pressing mold is provided with a second forming groove which is used for matching with a curving radius of a neck part of a clamping hoop and extends leftwards and rightwards; the second lower pressing mold is also provided with a limiting structure which is used for stopping and limiting a first blank body in the front-and-back direction to determine a pressing and forming position of the neck part of the clamping hoop; the second upper pressing mold is provided with a second pressing head which is as same as the curving radius of the neck part of the clamping hoop and matches with the second forming groove. The limiting structure and the second forming groove of the clamping hoop U-shaped forming mold and the can determine the curving position of the neck part of the clamping hoop on the basis of ensuring the curving radius of the neck part of the clamping hoop, so that the position precision and processing precision of the clamping hoop are ensured, and the processing efficiency and the processing quality are increased greatly.

Description

Technical field [0001] The present invention involves molding molds, especially a type of card -shaped tooling and card -hoe U -shaped molding mold. Background technique [0002] With the rapid development of the aerospace industry, the level of manufacturing technology of aircraft has improved greatly.During the manufacturing process of the aircraft, many small and light weight connection parts need to be used. Figure 1-2 It is shown that in the process of manufacturing and processing of the aircraft, a large amount of use is needed. However, the production of this card hoop is generally used by handmade light tools for processing. The processing time is consuming and the production efficiency is low.It cannot meet the requirements and improve the waste rate. [0003] like image 3 It is shown in the card hoop body required for the processing card hoop. The card hoop billet 100 consists of four parts, including the front -end card hoop head 101, including the stuck binocular ears...

AI Technical Summary

Problems solved by technology

In the manufacturing process of the aircraft, many small and light connecting parts need to be used. There is a clamp such as Figure 1-2 As shown, it needs to be widely used in the manufacturing process of aircraft. However, the production of this kind of clamp is generally processed by hand light tools, which is time-consuming and has low production efficiency. At the same time, the clamp produced by hand has a lot of precision. Can not meet the requirements, increasing the scrap rate

[0003] like image 3 Shown is the clamp blank required for processing the clamp. The clamp blank 100 is composed of four parts, including the clamp head 101 at the front end, the clamp double ears 102 including the left and right ears, and the clamp neck 103 and the clamp tail 104 located at the rear end, the processing process of the clamp mainly includes three processes, the first process is to bend the ears 102 of the clamp and process the first blank, the structure of the first blank is as follows Figure 4 As shown, the second process is to bend the clamp neck 103 and process it into a second green body, the structure of the second green body is as follows Figure 5 As shown, the third process is to flatten the clamp tail 104 and process it into a finished clamp. The existing second process is generally directly bent by hand, which often has inaccurate bending radius and clamp The parallelism between the head and the tail of the clamp does not meet the requirements, which brings great troubles to subsequent processing and use.
