Abstract
The invention relates to a bottleneck type shell case which comprises a shell case body and a centerfire chamber holder, wherein the centerfire chamber holder is welded at the bottom inside the shell case; a centerfire hollow chamber is arranged at the lower part of the centerfire chamber holder; the upper part of the centerfire chamber holder is connected to the internal sidewall of the shell case through a connecting seat in a manner of welding; and filling chambers are formed among the centerfire chamber holder, the connecting seat and the shell case body. The bottleneck type shell case is simple in structure, convenient to process; and with the adoption of the bottleneck type shell case, the process is simplified, the integral strength is improved, the weight is reduced, and the practicability is improved.
Description
Technical field
The present invention relates to a kind of shell case, particularly a kind of Bottleneck case.
Background technology
The bullet shell case is main with brass mainly, and brass ductility is good, and is little to the wearing and tearing of rifle, is the optimal material of bullet, but the price of copper is increasingly high now, and a lot of countries are all at the development steel case, in order to the instead of copper shell case.Existing steel case technology prematurity still, its manufacturing procedure is more, and manufacturing process is complicated, and the steel case weight that processes is heavier, can not satisfy the requirement of modernized army.
Summary of the invention
The objective of the invention is to overcome the problem that prior art exists, proposed Bottleneck case a kind of simple in structure, easy to process.
In order to achieve the above object, the technical scheme of the present invention's employing is:
A kind of Bottleneck case; Form by housing and fire in a stove before fuel is added chamber seat; Fire in a stove before fuel is added chamber seat is welded on the housing inside bottom; Seat bottom, fire in a stove before fuel is added chamber is provided with dress fire in a stove before fuel is added cavity, and its technical characterstic is that seat top, said fire in a stove before fuel is added chamber is welded to connect through Connection Block and housing madial wall, forms between fire in a stove before fuel is added chamber seat, Connection Block and the housing and fills the chamber.
Fill highstrenghtpiston or carbide alloy or aluminium in the said filling chamber.
Said case top is the bottleneck shape, and housing bottom is outside grab shape.
Said housing, Connection Block, fire in a stove before fuel is added chamber seat are stainless steel.
Compared with prior art, the beneficial effect that reaches of the present invention is:
The present invention is made up of housing and fire in a stove before fuel is added chamber seat, and fire in a stove before fuel is added chamber seat is welded on the housing inside bottom, and it is simple in structure, and is easy to process, has simplified operation, has improved efficient, has reduced cost; Form between fire in a stove before fuel is added chamber seat, Connection Block and the housing and fill the chamber, fill and fill highstrenghtpiston or carbide alloy or aluminium in the chamber, reduced the weight of shell case when having increased bulk strength, improved the Practical Performance of product.
Description of drawings
Fig. 1 is a structural representation of the present invention.
Among the figure: housing 1, Connection Block 2, fire in a stove before fuel is added chamber seat 3 is filled chamber 4, dress fire in a stove before fuel is added cavity 5, grab 6, bottleneck 7.
The practical implementation method
Below in conjunction with accompanying drawing the present invention is further specified.
Shown in the accompanying drawing, a kind of Bottleneck case is made up of housing 1 and fire in a stove before fuel is added chamber seat 3; Fire in a stove before fuel is added chamber seat is welded on the housing inside bottom, and said case top is bottleneck 7 shapes, and the bottom is outside grab 6 shapes; Seat bottom, fire in a stove before fuel is added chamber is provided with dress fire in a stove before fuel is added cavity 5; Seat top, fire in a stove before fuel is added chamber is welded to connect through Connection Block 2 and shell case madial wall, forms between fire in a stove before fuel is added chamber seat, Connection Block and the housing to fill chamber 4, fills and fills highstrenghtpiston or carbide alloy or aluminium in the chamber.
