Description

Aviation sheet spare tailors frock

Technical Field

The utility model relates to an auxiliary assembly of a punching machine, in particular to an aviation sheet cutting tool.

Background

The airplane sheet metal manufacturing technology is an important component of aerospace manufacturing engineering and is one of important manufacturing technologies for realizing structural characteristics of airplanes. The shell of a modern airplane is mainly a sheet metal riveting structure, and statistics shows that sheet metal parts account for about 50% of the number of airplane parts, sheet metal process equipment accounts for 65% of the total-airplane manufacturing process equipment, and the manufacturing workload accounts for 20% of the total-airplane workload.

Most of these sheet metal parts are sheet metal parts, and an anodic oxidation process is usually performed in the production process to improve the corrosion resistance and wear resistance of the parts. The parts need to be hung on the anode in the electrifying process of anodic oxidation, and 4 hanging holes need to be added on the edge of the original specification of the parts because the parts do not have the hanging holes in the production process. Because the required fineness of aviation sheet metal parts is higher, when a suspension hole is removed subsequently, the straightness of a straight line edge needs to be ensured within 0.1mm, and the processing difficulty is higher.

At present, the chinese patent that the publication number is CN210208263U discloses a die-cut mould of sheet metal component hanger auxiliary material, it includes mould and lower mould, it all is equipped with towards the incision to go up mould and lower mould, lower mould dashes the incision and is a flat edge, goes up the mould and dashes the incision and be a level and smooth edge in the notch, goes up the mould and dashes the incision and the die-cut incision counterpunching of lower mould and cuts off the hanger auxiliary material of sheet metal component, the lower mould is equipped with the striker block in lower mould dashes incision both sides, the sheet metal component main part supports the striker block during die-cut.

Although this kind of die-cut mould of sheet metal component hanger auxiliary material can cut high-efficiently, nevertheless need operating personnel to promote the sheet metal component with the hand and make it support and keep off the material piece and press fixed sheet metal component through the hand during shearing, it is dangerous when shearing. When the mental state is poor due to high-intensity operation of an operator, fingers are easily to be too close to the punching opening, so that danger is generated. Therefore, the auxiliary material punching die for the sheet metal part hanger has certain improved space in the aspect of safety.
