Description

Upper die for cutting flange skin

Technical Field

The application relates to the field of flange forging, in particular to an upper die for cutting a flange into skin.

Background

The flange is also called flange plate or flange at present. The flange is a part for connecting the shafts and is used for connecting pipe ends; there are also flanges on the inlet and outlet of the equipment for the connection between two pieces of equipment, such as reducer flanges. The production process of the flange mainly comprises four processes of forging, casting, cutting and rolling, wherein the number of the cast flange and the forged flange is large. The cast flange has the advantages of accurate blank shape and size, small processing amount and low cost, but has casting defects (air holes, cracks and inclusions); the internal structure of the casting is poor in streamline (if the casting is a cutting piece, the streamline is poor); the forged flange generally has lower carbon content than the cast flange and is not easy to rust, the forged piece has good streamline shape and compact structure, and the mechanical property of the forged flange is superior to that of the cast flange. The flange forging process mostly comprises the following process steps: s1: blanking, cutting the steel material into blanks according to the weight; s2: calcining, namely heating the blank to facilitate subsequent forging and pressing; s3: forging, wherein the blank is forged into a blank by a forging press, and the forging comprises the following three steps: s31: preliminary forging, performing preliminary forging on the blank to enable the blank to be close to the shape of a blank; s32: final forging, namely forging and pressing the blank again to ensure that the outer contour of the blank is the same as that of the blank, but the central part of the blank is provided with a connecting skin; s33: cutting the skin, namely cutting the skin of the blank to enable the blank to become a blank; s4: cooling, namely cooling the blank to room temperature; s5: and machining, namely machining the blank into a finished flange.

In view of the above-mentioned related technologies, the inventor thinks that in the process of cutting the skin, the hammer head of the forging press is usually used to cut off the continuous skin at the central part of the blank, but in the process of cutting the continuous skin by the hammer head, the blank is easily dislocated under the pressure of the hammer head, so that the error occurs in the cut skin.
