Description

Technical Field

[0001] The present invention relates to the technical field of process equipment, and particularly to an injection and shaping tool for initiating explosive devices and a shaping method thereof. Background Art

[0002] The gunpowder forming of a certain initiating explosive device adopts a process technology of casting with a shell, that is, a method of pouring liquid medicine into a shell for solidification. Due to the high viscosity of the liquid medicine, there are often phenomena such as the accumulation of medicine bodies at the injection port and poor flatness of the medicine surface after solidification, which affects the subsequent assembly of the charging shell. In previous scientific research and production, operators relied on work experience and used non-ferrous metal scrapers to scrape and shape the end face of the pouring port. It did not fit the medicine surface and the operation was laborious, and there was a risk of damaging the medicine surface. Therefore, a special tool for shaping the medicine surface is needed to deal with the uneven injection end face. Since the processed initiating explosive devices are flammable and explosive dangerous goods, to ensure the safety of the shaping process, tools in contact with gunpowder shall not use ferrous metals to eliminate the danger sources that can generate impact sparks. For example, non-ferrous metals with low density are used. Due to their light weight, the fit between the working surface of the tool and the gunpowder surface is not high, and the tool is prone to unilateral force during operation, resulting in local over-cutting of the medicine body. Summary of the Invention

[0003] In view of this, the present invention provides an assembled gunpowder forming medicine surface shaping tool, which not only ensures safety but also ensures weight for convenient operation by operators. It adopts multiple asymmetric double-angle cutting edges, and operators can quickly scrape the medicine surface flat. Specifically, it is an injection and shaping tool for initiating explosive devices and a shaping method thereof.

[0004] In order to achieve the above object, the present invention adopts the following technical solutions:

[0005] An injection and shaping tool for initiating explosive devices includes a tool mounting body, and a plurality of shaping cutting edges are fixedly installed at the bottom of the tool mounting body. The two sides of the shaping cutting edges are asymmetric double-angle cutting edges.

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

[0007] As an optimized solution of the above technical solution, the cutting edges are made of aluminum.

[0008] As an optimized solution of the above technical solution, a plurality of the shaping cutting edges are circumferentially and arrayedly distributed on the lower surface of the tool mounting body.

[0009] As an optimized solution of the above technical solution, the tool mounting body includes a tool body for installing the shaping cutting edges, a connecting body arranged on the upper surface of the tool body, and a handle arranged on the connecting body.

[0010] As an optimized solution of the above technical solution, the handle and the connecting body are made of ferrous metal material, and the tool body is made of aluminum.

[0011] The present invention also provides a shaping method for a shaping tool for filling and shaping explosive devices, comprising the following steps:

[0012] Step1. Align the shaping blade of the filling and shaping tool with the filling port of the explosive device and place it in;

[0013] Step2. Rotate the tool mounting body, thereby driving the rotation of the shaping blade. During the shaping process, when the forward rotation cutting resistance is large, manual reverse rotation cutting can be performed until the shaping of the drug surface morphology of the filling port is completed;

[0014] Step3. Repeat Step1 to Step2.

[0015] Compared with the existing technology, the beneficial effects of the present invention are:

[0016] The filling and shaping tool provided by the present invention has a simple structure, which is suitable for workers to operate in terms of tool weight and ensures safety. The structural characteristics of multiple blades and asymmetric double-angle blades can better adapt to the drug surface morphology in different complex situations, resulting in high shaping accuracy, easily completing the work of scraping the drug surface flat, improving both production quality and efficiency, and conforming to the principle of lean production.

[0021] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all of the embodiments.

[0022] In the description of the present invention, unless otherwise specified, "a plurality of" means two or more; the orientation or positional relationship indicated by terms such as "upper", "lower", "left", "right", "inner", "outer", "front end", "rear end", "head", "tail", etc. is based on the orientation or positional relationship shown in the drawings. It is only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be construed as a limitation on the present invention. In addition, terms such as "first", "second", "third", etc. are only used for descriptive purposes and cannot be construed as indicating or implying relative importance.

[0023] In the description of the present invention, it should be noted that, unless otherwise clearly specified and defined, the terms "connected" and "connected" should be understood in a broad sense. For example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be directly connected or indirectly connected through an intermediate medium. For those of ordinary skill in the art, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0024] As shown in the attached Figure 1 to the attached Figure 3 As shown, the technical solution of this embodiment mainly includes two parts: 1. The installation part of the shaping blade 1; 2. The shaping blade 1.

[0025] 1. The installation part of the shaping blade 1

[0026] The installation part of the shaping blade 1 is mainly for installing the shaping blade 1 and facilitating the user to take it. Its structure is mainly a connecting body 3 and a tool body 2 assembled together by screws. In order to make the working surface of the shaping blade 1 close to the powder surface during use, the connecting body 3 is made of a relatively heavy ferrous metal. Thus, during the shaping process, under the self-weight of the connecting body 3 and the tool body 2, the working surface of the shaping blade 1 can be made to closely adhere to the powder surface, preventing the tool from being stressed unilaterally and causing local over-cutting of the medicine body, thereby ensuring the flatness of the powder surface after shaping.

[0027] For the convenience of the user to take it, a handle 4 is inserted at the upper end of the connecting body 3. In order to increase the weight, the handle 4 can also be made of ferrous metal.

[0028] 2. The shaping blade 1

[0029] Six shaping blades 1 are fixedly arranged in a circular array on the lower end face of the tool body 2. The number of shaping blades 1 can be appropriately increased or decreased. At the same time, the shaping blade 1 is an asymmetric double-angle blade. Through the scraping processing of the tool with an asymmetric double-angle blade shape, the front and rear angles of the tool can be changed at any time according to the working direction and the morphology of the medicine surface. That is, when the forward rotation cutting resistance is large during operation, the reverse rotation cutting can be manually performed, making the operation easier and more adaptable to the complex medicine surface shape with different slopes and different stacking heights of the injection end face after solidification. The tool structure of the shaping blade 1 makes the force during the processing more balanced. The single reciprocating rotation cutting of the tool is equivalent to multiple feed processing of an ordinary tool, which improves work efficiency. The characteristics of the shaping blade 1 with this shape and multi-blade structure can more easily cope with the stacked medicine surfaces of different complex conditions during the processing process, providing more stable scraping and shaping.

[0030] The knife body 2 and the shaping blade 1 are the parts that come into contact with the medicine surface and are made of aluminum to ensure the safety of the operation process.

[0031] The method of using this technical solution is:

[0032] During operation, the operator holds the handle 4 with both hands, puts the shaping blade 1 into the injection port of the pyrotechnic product, and presses the knife body 2 against the medicine surface. The operator rotates the knife clockwise and counterclockwise repeatedly while moving on the medicine surface to scrape the medicine surface flat.

[0033] The above are only preferred specific embodiments of the present invention, but the scope of protection of the present invention is not limited thereto. Any technician familiar with this technical field, within the technical scope disclosed by the present invention, who makes equivalent replacements or changes based on the technical solutions and inventive concepts of the present invention, should be covered by the scope of protection of the present invention.
