Problems solved by technology

[0002] Usually, box parts with small rounded corners are formed by concave-convex die forming, hydroforming and other forming methods. For materials with room temperature formability, small rounded corner parts cannot be formed, and they are prone to breakage, and the mold with small rounded corners has poor processability and difficulty in processing.

Embodiment Construction

[0015] like figure 1 and figure 2 As shown, there are small rounded corners of R2 around the box parts. It is very difficult to make the overall concave-convex mold of such box parts, and the mold is easy to break.

[0016] like image 3 As shown, make as figure 1 and figure 2 The mold making process of the small rounded corner box parts shown includes the following steps:

[0017] 1) Process the split mold: Divide the mold into the base, the cover plate and the upper mold and process them separately. The cavity formed by it is the shape of the part to be processed. The upper mold adopts ordinary milling and grinding technology, and the upper and lower surfaces are parallel. The thickness is 0.05mm; the base is a hexahedron, using common milling and grinding technology, the parallelism of the upper and lower surfaces is 0.05mm;

[0018] 2) Drill air holes leading to the cavity on the upper template, which are used to connect high-purity argon gas, and form the sheet by ...

Abstract

The invention relates to a die manufacturing process for small round corner box type parts, and the method comprises the following steps: 1) processing a split die: dividing the die into a base, a sleeve plate and an upper die for processing respectively, wherein a formed cavity is in the shape of the parts to be processed; 2) drilling an air hole which is communicated with the cavity on an upperdie plate; 3) placing the base, the sleeve plate and the upper die at the center of a platform of a superplastic forming machine from bottom to top; 4) connecting with a pipeline and a temperature-measuring thermocouple, performing aeration and heating-up, and forming; and 5) drawing out of the die and forming after cooling to 100 DEG C. The process adopts a design method of the split die and further adopts a superplastic forming process, thereby enabling the die for the small round corner box type parts to be easy to process and achieving a good small round corner effect.

Description

technical field [0001] The invention relates to a mold manufacturing process for small rounded corner box parts, which is used for processing molds for parts with thin box walls and small rounded corners. Background technique [0002] Usually, box parts with small rounded corners are formed by concave-convex die forming, hydroforming and other forming methods. For materials with room temperature formability, small rounded corner parts cannot be formed, and they are prone to breakage, and the mold with small rounded corners has poor processability and difficult processing. big. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide a mold manufacturing process for small rounded box parts. Processing, and the effect of small rounded corners is good. [0004] In order to solve the above problems, the specific technical solution of the present invention is as follows: a mold manufacturing process for small rounded box par...
