the following detailed description will be made with reference to the accompanying drawings in conjunction with embodiments of the present invention.

Detailed Description

The invention will be further described with reference to the following drawings and examples:

as shown in fig. 1 to 3, a casting local deformation rapid shape correction device comprises a portal frame structure composed of a side beam 1 and a cross beam 2, wherein a slidable sliding base 6 is arranged on the cross beam 2, a jack 3 is arranged on the sliding base 6, a correction block 5 is arranged at the bottom of a piston rod of the jack 3, and a support mechanism capable of being adjusted up and down is arranged on the side beam 1.

Furthermore, a top rod 7 is screwed on the sliding base 6, so that the auxiliary fixing effect can be achieved.

Furthermore, the supporting mechanism comprises a supporting block 8 and a screw rod 9, a vertical groove is formed in the side beam 1, the supporting block 8 is arranged in the vertical groove in a sliding mode, the screw rod 9 is connected with the side beam 1 in a threaded mode, and the top of the screw rod 9 is connected with the supporting block 8 in a rotating mode. Supporting shoe 8 at both ends, the school shape piece 5 at middle part constitutes triangle-shaped load structure, the foundry goods both ends are supported on supporting shoe 8, remove the base 6 that slides to foundry goods deformation position, rotatory ejector pin 7 makes ejector pin 7 move down and compress tightly the foundry goods, later start jack 3, with school shape piece 5 pushes down, thereby carry out the school shape to deformation position, of course, also can not set up ejector pin 7, directly utilize jack 3, with school shape piece 5 pushes down, thereby carry out the school shape to deformation position, ejector pin 7 can play the effect of increasing steady.
