Description

Technical Field

[0001] The invention belongs to the technical field of flange forging, and in particular relates to a die used for flange forging. Background Art

[0002] Flange, also known as flange flange or flange, is a part that connects shafts to each other and is used to connect pipe ends. It is also used as a flange on the inlet and outlet of equipment to connect two devices, such as a reducer flange. When the flange needs to be forged, a mold is required.

[0003] The molds currently on the market have the following problems when used:

[0004] 1. When using traditional molds, it is necessary to hammer the metal material into the flange mold through repeated hammering. Due to the strong hammering force, it is easy to hammer the side of the mold, causing the mold to deform, affecting the subsequent use of the mold, and providing poor protection for the surface of the mold body;

[0005] 2. When using traditional molds, operators need to clamp them with pliers, clamp them and place them on the operating table for hammering and forging. Since the molds are made of metal and the sides are relatively smooth, they are prone to slipping during the clamping process, and their anti-slip effect is poor;

[0006] 3. When the traditional mold is used for flange forging, due to the high temperature of the flange material being hammered and forged, high-temperature debris will splash out during the hammering and forging process, which is easy to splash onto the operator, making it unsafe to use. Summary of the invention

[0007] The present invention aims to provide a die for flange forging to solve the technical problems raised in the background technology.

[0008] To achieve the above-mentioned purpose, the specific technical scheme of the present invention is as follows: a mold for flange forging, a protective ring is provided on the surface of the mold body, the bottom of the protective ring is fixedly connected to a rotating plate, the number of the rotating plates is two, a rotating groove is provided on the surface of the mold body, a card slot is provided inside the rotating plate, a card block is fixedly connected to the side of the rotating plate, the rotating plate is inserted into the rotating groove, and the card block is embedded in the card slot.
