Embodiment Construction

[0029] refer to Figure 1-Figure 7 . A method for preparing a target for a black box strong impact test, which mainly includes preliminary forming of a half-honeycomb panel, overall shaping of the half-honeycomb panel, superposition and assembly of the half-honeycomb panel and rubber strips, and overall high-temperature curing, wherein:

[0030] The preliminary forming of the semi-honeycomb panel uses a multi-station continuous mold combined with a press, and the feeder feeds the material according to the step distance, and the multi-station is processed and manufactured. According to the feeding direction from left to right, the multi-station includes fixed-distance feeding, single-tooth honeycomb forming, reserved material slippage, local shaping and cutting steps.

[0031] Such as figure 2 , image 3 As shown, fixed-distance feeding: the first processing of semi-honeycomb panel 1, the aluminum coil strip is installed on the feeder, and the feeder sends the aluminum coil...

Abstract

The invention discloses a manufacturing method of a black-box high impact test target. By using the method of the invention, defects that perforated malposition and malformation are generated, a splicing surface is in a point contact state and so on in a routine technology can be effectively avoided. A technical scheme is characterized in that during a die assembly process, molding punch pressure acts on an upper surface of an aluminum roll strip material of station reservation material slippage, an adjustable stock supporting plate (3) opens a die and holds up the reservation material slippage, half cellular holes which are interlacedly and uniformly distributed in a hexagonal perforated mode are formed tooth by tooth and a half cellular board is locally shaped; and then an integral shaping process is conducted and integral shaping of the half cellular board is completed; strip-shaped glue films (2) are spread on a perforated convex surface of the half cellular board (1) and are stacked on a positioning clamp, and cellulars are successively spliced to a needed height; then a spliced aluminum cellular semi-finished product and the positioning clamp are put into a high temperature baking oven so as to carry out integral solidification, a temperature is heated to 170 DEG C to 180 DEG C, heat preservation is performed for 2 hours, the temperature is reduced below 60 DEG C along with the oven and then the semi-finished product and the positioning clamp are taken out so as to realize rigid splicing between upper and low half cellular boards.

Description

technical field [0001] The invention relates to a preparation method of an elastic component target with high specific strength and specific stiffness, in particular to a preparation method of a honeycomb aluminum target for a black box strong impact load test. Background technique [0002] The shape of the metal honeycomb core includes regular hexagon, rhombus, rectangle, equilateral triangle, sinusoidal curve and other shapes, because the regular hexagonal honeycomb is the most widely used because of its low material consumption, simple manufacture and high structural efficiency. The preparation methods of the regular hexagonal honeycomb core mainly include stretching method and forming method. The stretching method is to apply glue strips on the material first, then laminate and glue the materials together, and finally stretch the laminated and glued materials into a honeycomb, and then cut it into the required size and put it into use. The prepared honeycomb core will b...
