Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of mold processing, in particular to a high-precision blanking and stretching integrated mold for an automobile filter. Background Art
[0002] In the prior art, during the actual processing of the automobile filter housing, Figure 1 As shown, the square sheet 100 needs to be cut into blanks 200, and then stretched into a shell 300. Currently, there are two main types of shell blanking and stretching molds. One is to first uniformly blank the sheet through a blanking mold, and then manually place the blanks, and then stretch the shell on another set of stretching molds to perform hexagonal processing. The other type of mold is processed in three steps with a robot. The sheet is blanked in the first step, and then the robot clamps the blanks to the second step for stretching, and the robot clamps the shell to the third step for hexagonal processing. The first processing method requires two sets of molds and manual feeding, which is not efficient. The second processing method has three independent steps, a complex mold frame, and a horizontal layout of the mold, which requires more processing space and a robot, which increases the cost of the mold.
