Description

Box-type module group knocking-detection die and method for forming Z-shaped ultra-long section by applying same

Technical Field

The invention relates to a box module group knocking detection die and a Z-shaped super-long sheet forming method, in particular to the field of aerial sheet bending forming Z-shaped super-long sheet processing.

Background

At present, the processing of the section bar in the field of aeronautical manufacturing occupies a large proportion, and particularly in the current stage of vigorously developing large airplanes in China, the existing method for the section bar with the small curvature is to use an integral tire to manually knock and repair the section bar. The die has the advantages of large consumption of manufacturing materials, long manufacturing period and high cost. The airplane industry in China is in a development stage at present, the design change amount of a part mechanism is large by searching and advancing, an integral tire knocking detection mold is selected for processing, once a digital-analog is changed, the mold can only be manufactured again, the mold manufacturing cost is wasted, the delivery cycle of airplane parts is delayed, and time and labor are wasted.

Disclosure of Invention

The invention aims to solve the technical problem of providing a box-type module group knock-out detection die and a method for forming a Z-type ultra-long material by applying the same.

In order to solve the above problems, the specific technical scheme of the invention is as follows: a box-type module group knocking detection die is characterized in that a base is connected to the lower surface of a box-type frame, the upper surface of the box-type frame is connected with a platform, a plurality of molding die modules are connected to the platform, and the outer shapes of the molding die modules are consistent with the curvature of a Z-shaped ultra-long material to be processed; a supporting block is arranged on the outer side of the tire molding module in the width direction, a jacking block is arranged on the supporting block, and the jacking block is tightly propped against the side surface of the Z-shaped ultra-long material to be processed; and a pressing plate is arranged on the supporting block and is tightly pressed with the upper surface of the bottom edge of the Z-shaped super-long section to be processed.

And no tyre molding module is arranged at the corresponding position of the Z-shaped super-long material with the curvature close to 0.

The two molding die blocks are symmetrically arranged on the box-type frame in parallel, and the shape curvatures of the two sides are symmetrical.

The method for forming the Z-shaped super-long section by adopting the box-type module group knock-out die comprises the following steps:

1) typical technological procedures are compiled according to engineering data and mould requirements, a module group is cleaned, a detection mould and a section bar are knocked, and labels and mark marks are hung;

2) straightening the Z-shaped ultra-long material to be processed, ensuring straightness and ensuring no bulge and scratch on the surface;

3) installing a Z-shaped ultra-long section to be processed at the side end of a molding bed module, positioning the section through a pressing plate and a jacking block, and ensuring that the shape of the section is attached to a molding bed line;

4) arranging operators with rich experience for construction, starting manual knocking forming from the middle tire molding module, realizing uniform knocking, ensuring uniform stress application by gradually scattering knocking positions, and ensuring smooth transition treatment of the knocking surface of the hammer;

5) and manually marking an outline according to the template after the Z-shaped super-long section is formed, carrying out numerical control milling to ensure the outline dimension, and manually aging to release stress, thereby completing the forming of the Z-shaped super-long section.

This box module group strikes examines mould adopts the type child module of components of a whole that can function independently structure to through clamp plate and kicking block location part, increased mould flexibility, variability, greatly reduced is because of the mould risk of scrapping that the part digifax change leads to, effectual reduction secondary reprocesses frock expense, has shortened the cycle of a large amount of secondary reprocesses frock. The local adjustment is flexible and convenient, and the method is an effective processing mode for bending and forming the section metal plate.

Meanwhile, the method for forming the Z-shaped ultra-long material applies a box-type module group knocking detection die, internal stress is hammered out from the middle to the two sides in an extending mode, and bulging deformation caused by stress superposition generated by knocking of different parts is avoided. The method for forming the knock-check die is simple and feasible, overcomes various difficulties, ensures the profile shape accuracy, effectively reduces the tooling cost and the repeated manufacturing risk brought by digital-analog change, and generates considerable economic benefit.
