Correction device applicable to shakeproof strip fulcrum and distortion

Abstract

The invention discloses a correction device applicable to shakeproof strip fulcrums and distortion. The correction device comprises a platform bracket, a correction platform, an upper pressing plate,a measuring device, correction handles and a correction fulcrum, wherein the correction platform is arranged at the top of the platform bracket; the correction handles are arranged on a side of the correction platform; the correction handles are used for exerting force to shakeproof strips through the correction fulcrum; the upper pressing plate is arranged on the upper surface of one end part ofthe correction platform; middle spacers are arranged between the upper pressing plate and the correction platform; high-strength bolts are arranged on the upper pressing plate; the high-strength boltsare used for applying a force to the middle spacers; and a measuring device is connected with the upper pressing plate or the correction platform through a magnetic base. By adopting the correction device, distortion deformation caused in the machining process of shakeproof strips can be corrected, manufacturing raw materials can be saved, the working allowance can be greatly reduced, the machining time is shortened, the rejection rate is reduced, and thus the production cost is lowered.

Description

technical field [0001] The invention relates to parts processing technology, more specifically, to a correction device suitable for the fulcrum and twist of an anti-vibration bar. Background technique [0002] The nuclear power passive waste heat removal heat exchanger is the core equipment of the passive core cooling system, which provides emergency core decay heat removal function and plays an important role in the safe operation of the reactor. The waste heat discharge heat exchanger is complex in structure and requires high technical difficulty. The anti-vibration bar (also known as: residual anti-vibration bar) used in the nuclear power passive waste heat removal heat exchanger is a key component of the nuclear power passive waste heat removal heat exchanger. The shape of the anti-vibration bar is thin and rectangular. The size is 1590mm long × 18.67mm wide × 13.7mm wide. The part is a slender part. The straightness requirement is 1mm in total length, but the twisting ...

AI Technical Summary

Problems solved by technology

However, this kind of processing method not only needs to carry out the process test in the early stage to confirm that the margin required for the completion of the anti-vibration bar is sufficient, but also has a long manufacturing cycle; moreover, the processing volume is large, raw materials are wasted, and the processing cost is high.

The anti-vibration bar distortion is affected by the verticality, parallelism, straightness and flatness of the part, the scrap rate of the part is very high, and the distortion of the part is uncontrollable

Therefore, for slender parts of the anti-vibration strip type, machining removal can not meet the technical requirements of the above parts at all
