Abstract
The invention discloses a loose tooling forging technology of an I-shaped forge piece with holes. The loose tooling forging technology comprises the following steps of: (1) manufacturing a blank with the first fire, to be specific, drawing out the blank through great pressure, forging the blank with a loose tooling, firstly upsetting a large flange at one end of the blank in a preforging mold and upsetting a large flange at the other end of the flange in a forming mold, removing an external mold sleeve, opening two inner inserts, taking out a forging blank, punching and chambering outside the mold, and leaving 0.5 degree-1 degree inclination on the preforging mold and circular beads on steps; and (2) forming with the second fire, to be specific, putting the forging blank on upper and lower flat anvils, forming in the forming mold, and punching and chambering the loose tooling outside the mold after filling a supporting mold. The loose tooling forging technology has the beneficial effects that loose tooling forging technology has no strict requirements on the technique of workers, is simple and convenient to operate and is high in production efficiency; the design of the loose tooling is simple; the production efficiency is improved; the labor intensity is reduced; the size of forge pieces is controlled by using the mold; the percent of pass is greatly increased; and the loose tooling forging technology is suitable for producing the forge pieces with certain blanks.
Description
Technical field
The present invention relates to Forging Technology, be specifically related to the fetal membrane Forging Technology of work shape forging with holes.
Background technology
Traditional large-sized flange forging generally utilizes monoblock type loose tool to carry out forging, for oil, chemical industry
Industry needs the big specification flange forge piece used, in order to meet flange forge piece dimensional requirement and ensure
The intensity of loose tool, the loose tool wall thickness of large-sized flange forging is very big, quality is big, makes the manufacturing cost of flange forge piece
High；The quantity how reducing large-scale loose tool in the design and production of loose tool, the flange making full use of in stock
Loose tool, the cost of reduction flange forge piece are the difficult problems faced in modern forging enterprise, rely on artificial mode,
Use conventional methods and carry out the loose tool manufacture of large-sized flange forging and cannot solve an above-mentioned difficult problem.
Summary of the invention
For solving technical problem described in background technology, the present invention by the following technical solutions: the forging with holes of work shape
The fetal membrane Forging Technology of part, it comprises the following steps:
1) the first fire preparing base: weight pulling blank, available fetal membrane forges, first by blank jumping-up in blocker
One end large flange, and jumping-up other end large flange in mould, remove outer die casing, insert in opening two,
Take out forging stock, the outer punching reaming of mould, blocker to leave the gradient of 0.5 °-1 °, leaves fillet at step,
Convenient torr mould initial forging temperature controls at 1000-1300 DEG C；Final forging temperature controls at 700-900 DEG C；
2) the second pyrogene type: be placed on upper and lower flat anvil, in-molded in molding, completely rush outside mould after torr mould
Hole, reaming fetal membrane size, initial forging temperature controls at 1000-1200 DEG C, and final forging temperature controls at 700-900 DEG C；
3) put in storage through the conformance with standard regulation that examines the forged pieces.
In step 1) in shaping mould include outer die casing and interior insert two parts and constitute, outer die casing inwall leaves
The gradient of 3 °, interior insert divides equally two parts in axial location, and for being open, inwall need not stay gradient,
Outer wall coincide with outer die casing, stays the gradient of about 3 °.
The invention has the beneficial effects as follows: this technique is less demanding to workman's technology, easy and simple to handle, production efficiency
High；Fetal membrane design is simple, raising production efficiency, reduction labor intensity, forging's block dimension mould control, greatly
Improve greatly qualification rate, the forging being suitable for certain blank produces.
