Description

Technical Field

[0001] The present invention relates to the technical field of engine cylinder head forging, and particularly to an engine cylinder head forging and processing device for automobile parts processing. Background Technique

[0002] Forging and pressing is the combination of forging and stamping. It is a forming processing method that uses forging and pressing machinery to apply pressure to metal blanks, causing them to undergo plastic deformation, so as to obtain workpieces with the required shapes and dimensions. Forging and pressing applies pressure to the blanks through the hammer heads, anvil blocks, punches of forging and pressing machinery or through dies, causing them to undergo plastic deformation, so as to obtain workpieces with the required shapes and dimensions. During the forging process, the overall blank undergoes obvious plastic deformation and has a large amount of plastic flow. Forging and pressing, rolling, drawing, etc. in the metallurgical industry all belong to plastic processing, but forging and pressing are mainly used for producing metal workpieces;

The arc block 15 can slide inside the circular ring groove 13, so that the clamping component 5 can rotate around the forging press 2 inside the circular ring groove 13, so as to adjust the angle when the clamping component 5 flips the automobile engine cylinder head. The moving frame 18 can slide inside the through-hole plate 17, and the clamping component 5 can adjust the distance from the forging press 2 through the moving frame 18, so that the operator can better use the clamping component 5 to flip the automobile engine cylinder head. The sliding connection between the arc block 15 and the inner wall of the circular ring groove 13 supports the clamping component 5, and the operator can reduce the force when using the clamping component 5 to clamp the automobile engine cylinder head.
