Description

Technical Field

[0001] The utility model relates to the technical field of core bar correction equipment, in particular to a core bar correction device for casting. Background Art

[0002] The core bone is a metal frame, which is placed in the core during casting to improve the strength and rigidity of the core. In order to assist the core bone to be stably installed in the core during the casting process, a core bone correction device for casting is required.

[0003] During use, traditional casting core bone correction devices mostly place the core bone on the top of the placement table, then manually adjust the bolts, use the auxiliary bracket and the placement table to limit the core bone, and then use the pneumatic telescopic rod to drive the pressure plate to move down, so as to use the pressure plate to hammer and correct the core bone. However, during use of the above-mentioned device, on the one hand, when the traditional device is limiting the core bone, it is difficult to ensure that the two ends of the core bone are clamped and limited during the hammering of the middle section of the core bone, which results in the two ends of the core bone moving to both sides when the middle section of the core bone is hammered and moved downward, which can easily cause the two ends of the core bone to wear against the clamping equipment, thereby affecting the stable use of the core bone.
