Embodiment Construction

[0030] Refer to Figure 1-Figure 7 . A preparation method of a black box strong impact test target mainly includes the preliminary forming of the semi-honeycomb panel, the overall shaping of the semi-honeycomb panel, the stacking and assembly of the semi-honeycomb panel and the rubber strip, and the overall high-temperature curing, among which:

[0031] The preliminary forming of the semi-honeycomb panel uses a multi-station continuous mold combined with a press, and the feeder feeds materials according to the step distance, and is manufactured by multi-station processing. According to the feeding direction from left to right, the multi-station includes fixed-distance feeding, single-tooth honeycomb forming, reserved material slippage, partial shaping and cutting steps.

[0032] 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 str...

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 method for preparing an elastic member target with high specific strength and specific rigidity, in particular to a method for preparing a honeycomb aluminum target for a black box strong impact load test. Background technique [0002] The shape of the metal honeycomb core is regular hexagon, rhombus, rectangle, equilateral triangle, sine curve, etc. The regular hexagonal honeycomb is most widely used because it saves materials, is simple to manufacture and has high structural efficiency. The preparation methods of the regular hexagonal honeycomb core currently mainly include the stretching method and the forming method. The stretching method is to first apply a rubber strip on the material, then glue the material together, and finally stretch the laminated and glued material into a honeycomb, and then cut it to the required size before it can be put into use. This method is adopted. The prepared honeycomb core will be affected b...
