Problems solved by technology

However, the wool of deep-drawn parts is usually in a regular shape such as a rectangle or a circle, and it is difficult to carry out accurate drawing of curved surface structural parts. Because of the implementation of the flat wrinkle function of the blank holder ring, the distribution of the blank holder force on the edge tends to be uniform; especially in the design of special-shaped thin plate structural parts, it is difficult to effectively calculate the blank holder force and punching force, and improper proportioning may easily cause forming defects in parts. For blank holder Force regulation requires a lot of experimentation and exploration

Embodiment Construction

[0019] The present invention will be further described below through specific examples.

[0020] Material selection: choose 316 stainless steel plate as the blank, calculate the size according to the size of the steel cylinder, and then use a cutting machine to cut the blank into circular plates according to the calculated target size;

[0021] Solution treatment: solution treatment is carried out on the cut circular plate, and the temperature is kept at 1850-2050°F for 30 minutes or more, and then cooled rapidly;

[0022] Grinding: Grinding the surface to remove the burrs;

[0023] Deep drawing: The polished blank is subjected to the first cold drawing, and then the above solid solution treatment step is carried out after the first cold drawing, and then the second cold drawing is carried out, and the blank after the second cold drawing is subjected to the second cold drawing. Three times of hot drawing and shaping, and pressure-holding treatment during the third hot drawing...

Abstract

The invention discloses a deep-drawing production technique for stainless steel shuttle-shaped artware. The deep-drawing production technique for the stainless steel shuttle-shaped artware comprises the steps of material selection, solid solution treatment, polishing, deep drawing, cutting, cleaning, primer spraying, surface paint spraying and the like. First-time cold deep drawing is conducted on a polished blank, the step of solid solution treatment is conducted after first-time cold deep drawing, then second-time cold deep drawing is conducted, third-time hot deep-drawing correction is conducted on the blank subjected to second-time cold deep-drawing, pressure maintaining treatment is conducted during third-time hot deep drawing correction, and thus the production efficiency and attractiveness degree of the shuttle-shaped artware are effectively improved.

Description

technical field [0001] The invention relates to the field of deep-drawing in thermoforming, and specifically relates to a deep-drawing production process for stainless steel shuttle-shaped handicrafts. Background technique [0002] At present, in the thermoforming process, for special-shaped thin plate structural parts, deep drawing forming or stamping without blank holder is generally adopted. However, the wool of deep-drawn parts is usually in a regular shape such as a rectangle or a circle, and it is difficult to carry out accurate drawing of curved surface structural parts. Because of the implementation of the flat wrinkle function of the blank holder ring, the distribution of the blank holder force on the edge tends to be uniform; especially in the design of special-shaped thin plate structural parts, it is difficult to effectively calculate the blank holder force and punching force, and improper proportioning may easily cause forming defects in parts. For blank holder ...
