Description

Technical Field

[0001] This utility model relates to the field of process equipment technology, and in particular to a pyrotechnic injection shaping tool. Background Technology

[0002] The propellant forming of a certain pyrotechnic product employs a shell-casting process, where liquid propellant is poured into a shell and solidifies. Due to the high viscosity of the liquid propellant, after solidification, propellant often accumulates at the injection port, resulting in uneven propellant surface flatness, thus affecting subsequent assembly of the casing. In the past, during research and production, operators relied on experience, using a non-ferrous metal scraper to scrape and shape the injection port end face. This method was not adhering well to the propellant surface, was laborious, and posed a risk of damaging the propellant surface. Therefore, a specialized tool for propellant surface shaping is needed to address unevenness at the injection port end face. Since the pyrotechnic product being processed is a flammable and explosive hazardous material, to ensure safety during the shaping process, tools handling the propellant must not be made of ferrous metals to eliminate the risk of impact sparks. If low-density non-ferrous metals are used, their lighter weight results in poor contact between the tool's working surface and the propellant surface, leading to unilateral force application and localized over-cutting of the propellant. Utility Model Content

It employs multiple asymmetrical double-angled blades, allowing operators to quickly smooth the gunpowder surface. Specifically, it is a gunpowder injection shaping tool for pyrotechnic products.

[0005] A pyrotechnic propellant shaping tool includes a tool mounting body, on the bottom of which a plurality of shaping blades are fixedly mounted, wherein the two sides of the shaping blades are asymmetrical double-angled blades.

[0006] As a further improvement to the above technical solution:

[0007] An optimized version of the above technical solution is that the blade is made of aluminum.

[0008] An optimized version of the above technical solution is that a plurality of the shaping cutting edges are distributed in a circumferential array on the lower surface of the tool mounting body.

[0009] An optimized version of the above technical solution is that the tool mounting body includes a tool body for mounting the shaping blade, a connecting body disposed on the upper surface of the tool body, and a handle disposed on the connecting body.

[0010] An optimized version of the above technical solution is that the handle and the connecting body are made of ferrous metal, and the blade body is made of aluminum.

[0017] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0018] In the description of this utility model, unless otherwise stated, "a plurality of" means two or more; the terms "upper," "lower," "left," "right," "inner," "outer," "front end," "rear end," "head," "tail," etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings, and are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this utility model. In addition, the terms "first," "second," "third," etc., are used for descriptive purposes only and should not be construed as indicating or implying relative importance.

[0019] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "connected" and "linked" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0020] As attached Figure 1 To be continued Figure 3 As shown, the technical solution of this embodiment mainly includes two parts: 1. The mounting part of the shaping blade 1; 2. The shaping blade 1;

[0021] I. Installation of the shaping blade 1

[0022] The mounting part of the shaping blade 1 is mainly for mounting the shaping blade 1 and for easy handling by users. Its structure is mainly composed of the connecting body 3 and the blade body 2 assembled together by screws. In order to ensure that the working surface of the shaping blade 1 is in close contact with the gunpowder surface during use, the connecting body 3 is made of heavy ferrous metal. Thus, during the shaping process, the working surface of the shaping blade 1 is kept in close contact with the gunpowder surface by the weight of the connecting body 3 and the blade body 2, preventing the tool from being subjected to force on one side and causing local over-cutting of the gunpowder, thereby ensuring the flatness of the gunpowder surface after shaping.

[0023] To make it easier for users to hold, a handle 4 is inserted into the upper end of the connector 3. To increase the weight, the handle 4 can also be made of black metal.

[0024] II. Shaping Blade 1

[0025] Six shaping blades 1 are fixedly arranged in a circumferential array on the lower end face of the blade body 2. The number of shaping blades 1 can be appropriately increased or decreased. The shaping blades 1 are asymmetrical double-angled blades. Through scraping with this asymmetrical double-angled blade shape, the front and rear angles of the blade can be changed at any time according to the working direction and the shape of the drug surface. That is, when the cutting resistance is high during forward rotation, the blade can be manually rotated in the opposite direction for cutting, making the operation smoother and more adaptable to complex drug surface shapes with varying slopes and accumulation heights after curing. The tool structure of the shaping blades 1 makes the force distribution during processing more balanced. A single reciprocating rotation of this blade is equivalent to multiple feeds of a conventional tool, improving work efficiency. The shape and multi-blade structure of the shaping blades 1 allow them to more easily handle different complex drug surface conditions during processing, providing more stable scraping and shaping.

[0026] The blade body 2 and the shaping blade 1 are the parts that come into contact with the medicine surface. They are made of aluminum to ensure the safety of the operation process.

[0027] The method of using this technical solution is as follows:

[0028] During operation, the operator holds the handle 4 with both hands, places the shaping blade 1 into the injection port of the pyrotechnic item, and keeps the blade body 2 close to the pyrotechnic surface. The operator rotates the blade clockwise and counterclockwise repeatedly while moving it over the pyrotechnic surface to smooth it.

[0029] The above are merely preferred embodiments of this utility model, but the scope of protection of this utility model is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in this utility model, based on the technical solution and inventive concept of this utility model, should be included within the scope of protection of this utility model.
