Description

CCB skeleton Z-direction manual correction device

Technical Field

The utility model relates to a processing accessory of an automobile part, in particular to a correction device of a CCB framework.

Background

Part of the CCB die casting is influenced by the structure of the CCB die casting, and x-direction deformation and z-direction deformation can occur in the die casting-demolding process; wherein the definition of x-direction and z-direction is: taking the position of the seat as the reference, and taking the front-back horizontal direction as the x direction; taking the left and right horizontal directions as y directions; the vertical direction is z direction.

Fig. 1 shows an external view of a CCB skeleton when released from mold, and the CCB skeleton is deformed due to:

1. the width of the girder is narrower than the side area, and the girder is deformed due to the pulling of the wider areas at the two sides during die casting, so that the size is out of tolerance;

2. as the solidification and cooling of the runner are slowest, the product can be contracted and pulled by the runner to generate deformation, as shown by an arrow in fig. 1;

3. the continuous cooling of the runner after the die casting ejection can be added to the pulling of the product to increase the deformation of the girder;

4. for large thin-wall die-casting products, the deformation amplitude of die opening and ejection is about 3mm, the unilateral deformation of the die-casting process is controlled within 1mm, and the yield is difficult to improve;

therefore, in the case that the existing technology cannot meet the processing requirements, the qualification rate needs to be ensured through a later calibration procedure.
