Abstract
A fireworks is composed of internal shell consisting of two hollow semi-balls, external shell consisting of two hollow semi-balls, and is prepared through filling explosive in the internal shell, die pressing to form a whole, coating adhesive on its surface, and adhering the external shell to it. Its advantages are simple structure, high safety, quality and accuracy,and easy manufacture.
Description
The invention discloses a kind of display shell and manufacture method thereof.
Traditional display shell manufacturing process is that gunpowder is filled in the mold pressing inner casing, paste several layers paper repeatedly on the inner casing surface then, every stickup one deck, after all must waiting it to dry, paste other one deck again, each layer pasted and the dry cycle is more than 10 hours at least, for the bigger display shell of diameter, it is pasted the number of plies and reaches the 30-40 layer, and therefore, its production cycle is quite long, and when pasting, be that the band medicine is pasted, the security of operation is lower, and operator's personal safety does not have guarantee, thereby, be necessary the production technology and the shell mechanism of existing display shell are improved,, improve the security and the production efficiency of operation to improve operator's work situation.
The objective of the invention is to overcome the deficiency of prior art and provide a kind of simple in structure, processing and manufacturing is easy, processing safety height, display shell that production efficiency is high and manufacture method thereof.
The present invention adopts following proposal to realize: the molded case that the mold pressing inner casing that it is made up of two hollow hemisphere and two hollow hemisphere are formed constitutes, be filled with explosive in the mold pressing inner casing and be a spheroid by the mould pressing, outer surface of spheroid is coated with adhesive, and two hollow molded cases are wrapped in the inner casing spherome surface.
Manufacture method of the present invention is to fill up gunpowder in the inner casing of compression molding, is a spheroid by moulding press with two inner casing pressings, at the outer surface of spheroid coated with adhesive, the shell of two compression moldings is wrapped this spheroid, then, be a spheroid by moulding press with the shell pressing and make inside and outside shell be bonded as one.
Concrete structure of the present invention describes in detail below in conjunction with accompanying drawing:
Accompanying drawing is master's cutaway view of the present invention.
See accompanying drawing, the present invention is made up of explosive 1, inner casing 2,3, shell 4,5, and described explosive 1 is loaded in inner casing 2,3 and is a spheroid by the mould pressing, and its outer surface is coated with adhesive, and shell 4,5 is wrapped in the outer surface of inner casing 2,3.
Manufacture method of the present invention is sketched in following: earlier with inside and outside shell compression molding, in inner casing, fill up explosive and it is pressed into a spheroid by mould, apply one deck adhesive at outer surface of spheroid, then shell is wrapped in the inner casing surface and shell is compressed, shell and inner casing are bonded as one by mould.
The present invention can simplify the production technology of display shell effectively owing to adopt said structure and production technology, shortens the production cycle of display shell, improves the security of display shell manufacture process; Improve operator's working condition, and, can effectively improve the accuracy of manufacture of display shell because inside and outside shell all adopts die press technology for forming, housing diameter is able to effective assurance, reduce card thorax when setting off, the generation of thorax phenomenon partially improves reliability and security that display shell is seted off.
In sum, the present invention is simple in structure, and processing and manufacturing is easy, produce and safe to use, with short production cycle, can effectively improve the accuracy of manufacture and the quality of display shell, reduce the generation of security incident, can realize industrialized production, be suitable for renewal product as existing display shell.
