Overturning device and overturning method for large plate parts

Abstract

The invention belongs to the technical field of machining tool devices, and discloses a large plate part turning device. One end of a first rotary part and one end of a second rotary part are connected to a rotating shaft. Body frames of the two rotary parts are each of a rectangular structure. Beams are arranged below the body frames. The height of the upper surfaces of the beams is smaller than the height of side beams on the peripheries of the frames. The height of the side beams is smaller than the thickness of plate parts. A plurality of lower supports are arranged on the beams. Side supports are arranged on the side beams on at least two opposite sides. The lower supports limit the perpendicular freedom degree of the parts. The side supports limit the horizontal freedom degree of the parts. Hanging lugs are arranged on the outer lateral sides of the two rotary parts respectively and are staggered. The invention further discloses a rotating method using the device. Workpieces are prevented from generating impact, external force and other effects in the turning process, safe, reliable and risk-free turning is implemented, product quality is ensured, and the cost for processing non-conformance terms is reduced.

Description

technical field [0001] The invention belongs to the technical field of machining tooling equipment, in particular to an overturning device and a overturning method for large plate parts. Background technique [0002] In the pressurized water reactor type nuclear reactor, there are many large plate parts, and they are all key parts, so the material and manufacturing costs are relatively high. According to the traditional overturning method, the workpiece will often produce impacts and other phenomena during the overturning process, resulting in deformation and affecting product quality. Especially after the workpiece is finished, the position accuracy of its relevant hole system is very high. If it is turned over in the traditional way, there is a risk of non-conformity items, and the cost of dealing with non-conformity items is very high. In addition, in the blank stage of the workpiece, there is no through hole on the workpiece, so it is difficult to turn over according to...

Problems solved by technology

[0005] In this traditional overturning method, the ropes are bound through the through holes on the workpiece. When the workpiece is overturned, due to the weight of the workpiece itself, it will cause local deformation of the workpiece, especially after the workpiece has been turned over and finished, it will affect the deformation of the workpiece. Precision creates quality risk

In addition, some workpieces have no through holes. If they need to be turned over, they cannot be realized by traditional turning methods.
