Description

Saddle frame for forging conical cylinder

Technical Field

The utility model belongs to the technical field of the forging apparatus technique and specifically relates to relate to forge and use horse, the utility model provides a conical drum forges and uses horse.

Background

The conical cylinder is a transition piece connected between the upper cylinder and the lower cylinder and the seal head in nuclear power steam generator equipment, and the upper diameter and the lower diameter of the conical cylinder are different, and the wall thickness of the conical cylinder is the same. By adopting the method of directly forging the cone, more than 50% of materials can be saved, the production period is shortened, and the structural reliability of the equipment is improved, but because the cone cylinder body is made of special materials and has large size, the angle of the cone cylinder body is difficult to control in the forging process, the larger the diameter of the large end is, the more difficult the diameter of the large end is to control in a plane, the distortion is generated along with the angle, and the processing size is out of tolerance and cannot be repaired until the forged piece is scrapped. Not only delays the delivery period, but also causes great loss to enterprises.

In order to solve the problems, a Chinese patent with the patent number of 200910011181.7 discloses a forming process and a forming device for a straight-edge conical barrel forging of a nuclear power evaporator, wherein a torque correcting block is placed on a base of a horse frame and used in cooperation with a horse bar, the torque correcting block is arranged at a position which ensures that the axis of a forging blank and the axis of the horse bar are always in the same plane and keep a certain angle, and the angle is consistent with the taper of a final part. The distortion block is of a cuboid structure, and the circumferences of the large end and the small end of the cone-shaped cylinder structure are different, so that the axis of the cone-shaped cylinder deflects when the horse is rotated, a screw hole is expanded, and the size of a forged piece cannot be guaranteed. The deflection of the axis of the conical barrel can be corrected by arranging the torque correction block, the axis of the conical barrel and the axis of the bumper are always in the same plane, and the spiral reaming is avoided. In the reaming process of the conical cylinder, the taper of the forging piece is dynamically changed. The inclination angle of the conical cylinder forging in the reaming process can be adjusted by arranging the torque correction block, the taper of the forging is guided to approach to a final target, and the final taper requirement of the forging is guaranteed.

However, the torsion correcting block in the patent is of a cuboid structure, the size of the torsion correcting block is fixed, the torsion correcting blocks with different sizes need to be configured for conical barrels with different specifications, and more materials need to be used for manufacturing the torsion correcting blocks with different sizes, so that the production cost is increased, and the waste of resources is caused; and more straightening blocks are not easy to store and need to be respectively marked with sizes; and the torque correcting block and the horse frame need to be installed, so that when the torque correcting blocks with different sizes are replaced, more time is wasted by installing and detaching the torque correcting blocks, the forging time is prolonged, and the forging efficiency of the conical barrel is reduced.
