Description

Technical Field

[0001] The invention relates to a surface treatment tool for an aerospace gas path system, in particular to a curved surface combined printing tool. Background Art

[0002] A certain type of missile needs to use a high-pressure gas cylinder to provide gas source, and the outer surface of the gas cylinder needs to be specially marked. The existing printing method is manual filling, and the bonding strength and appearance quality are poor. At present, the commonly used inkjet tools include adhesive molds, plastic molds, copper molds, screens, etc. They are mainly used for printing repetitive and batch words, and there is no variable word surface printing tooling. Summary of the invention

[0003] In view of the problems existing in the above-mentioned prior art, the present invention provides a detachable curved surface combined printing tooling, which realizes variable digital spray molding through modular design, thereby solving the problem that the marking area of ​​the gas cylinder can only be filled in manually at this stage.

[0004] The technical solution of the present invention is as follows:

[0005] A curved surface combined printing tool comprises a fixed character mold body, a mold body, a character piece, a pressure plate, a baffle and a handle. The mold body is an arc-shaped structure, baffles are respectively arranged at both ends of the arc-shaped mold body, handles are respectively arranged at the upper and lower parts of the arc-shaped mold body, a fixed character mold body is arranged on one side of the arc-shaped mold body, a stepped groove is arranged on the other side of the arc-shaped mold body, the character piece is embedded in the stepped groove, and the outer surface of the stepped groove is fastened to the pressure plate.

[0006] The mold body is made of LF1 aluminum alloy. The stepped grooves are arranged in multiple rows horizontally, and barriers are arranged between each row of stepped grooves. Bolt holes are processed around the stepped grooves to fasten the pressure plate.

[0007] The fixed character mold body is a leaking mold with a fixed character shape; the fixed character mold body is made of H62 copper alloy with a thickness of 0.5mm.

[0008] The shape of the main body of the character piece matches the shape of the stepped groove. Both ends of the main body of the character piece are provided with mounting inserts, which are inserted between the mold body and the pressing plate and fastened by bolts.

[0009] The character sheet is made of H62 copper alloy with a thickness of 1.5, and the surface of the character sheet is provided with a character mold to be marked.

[0010] The main body of the pressing plate is in the shape of a rectangular strip, the width of which matches the partition width of the stepped groove, mounting ears are arranged at both ends of the main body of the pressing plate, bolt holes are arranged on the mounting ears, and the pressing plate is fastened to the mold body by bolts.

[0011] The pressing plate is made of 2.5mm wide 45# steel.

[0012] The baffle is L-shaped and is fastened to the mold body by bolts.

[0013] The positive effects of the present invention are as follows:

[0014] The mold body mainly plays the role of forming and fixing the letter pieces. The combined letter pieces are attached to the stepped groove of the mold body through the pressing plate. The fixed letter mold body is a pre-processed leak mold, and the fixed and unchanging letters are sprayed onto the surface of the bottle body through the fixed letter mold body in advance. Through the cooperation of the two, the efficient spraying of the fixed letter part is improved, and the real-time adjustment of the variable letter part is solved, and the problems of neat handwriting and low efficiency of manual filling are solved. Through the comparison of the actual spraying, the marking quality meets the design requirements. Through the tooling design, not only the problem of the limitation of cylindrical surface marking is effectively solved, but also a new process method of combined printing tooling is opened up. It is of great value to the curved surface printing technology. BRIEF DESCRIPTION OF THE DRAWINGS

[0028] As shown in the figure, a curved surface combination printing tool comprises a fixed character mold body, a mold body, a character piece, a pressure plate, a baffle and a handle. The mold body is an arc-shaped structure, baffles are respectively arranged at both ends of the arc-shaped mold body, and handles are respectively arranged at the upper and lower parts of the arc-shaped mold body. The arrangement of the handle facilitates the fixation and mold separation of the curved surface combination printing tool and the coated workpiece. The root of the handle is an M8 threaded column and is fixed to the mold body by threads. A fixed character mold body is arranged on one side of the arc-shaped mold body, and a stepped groove is arranged on the other side of the arc-shaped mold body. The character piece is embedded in the stepped groove, and the outer surface of the stepped groove is fastened to the pressure plate.

[0029] The mold body is made of LF1 aluminum alloy. The stepped grooves are arranged in multiple rows horizontally, and barriers are arranged between each row of stepped grooves. Bolt holes are processed around the stepped grooves to fasten the pressure plate.

[0030] The fixed character mold body is a leaking mold with a fixed character shape; the fixed character mold body is made of H62 copper alloy with a thickness of 0.5mm and good formability.

[0031] The shape of the main body of the word sheet matches the shape of the stepped groove. Both ends of the main body of the word sheet are provided with mounting inserts, which are inserted between the mold body and the pressure plate and fastened by bolts. The word sheet needs to be easy to process and easy to etch. Considering that the thickness has a great influence on etching, the strength of the word sheet that is too thin cannot be guaranteed, and the etching difficulty is increased if it is too thick. In addition, the thickness of the word sheet will also affect the effect of spraying. It has been verified that the word sheet uses 1.5 thick H62 copper alloy, and the surface of the word sheet is provided with a mold for the word to be marked.

[0032] The main body of the pressing plate is in the shape of a rectangular strip, the width of which matches the partition width of the stepped groove, mounting ears are arranged at both ends of the main body of the pressing plate, bolt holes are arranged on the mounting ears, and the pressing plate is fastened to the mold body by bolts.

[0033] The design of the pressing plate needs to ensure that it does not interfere with the leakage part of the letter piece and can achieve effective pressing. Combined with the printing area of ​​the letter mold, the width of the pressing plate is designed to be 2.5, and the material is 45 steel, which is bluing treated.

[0034] The baffle is L-shaped and is fastened to the mold body by bolts to ensure that the non-spraying area is not contaminated during the spraying process.
