Description

A kind of assembling die of prefabricated annular forging piece cast steel base
Technical field
The utility model relates to a kind of machinery and forges the technical field with casting, and especially relating to a kind of its cross section of making is that the prefabricated component of the annular forging of circle or rectangle is the particular manufacturing craft of cast steel base.
Background technology
Big for its bearing load at present, the cross section that special technical requirement is arranged again is its physical dimension and all bigger annular type machine components of weight of circle or rectangle, all is that the forging that open die forging is made is made through operations such as machineds; All be to be that the hot-rolled square steel of 200-300 millimeter is heated to after the forging temperature with cutting or chopping blanking earlier, subsequently with this blank post bake and the cake of upsetting, punching, also reaming after heating for the third time, shaping again with the length of side; When being the square-section, its forging can be shaped; Can only preform when its forging is the garden tee section; Be not only the forging that circle and annular size are also big, weight is also bigger for its cross section, must carry out four heating could be shaped by finish-forgings, becomes qualified forging.
In these conventional forging process, its positive one side is arranged, like the metallic fiber good directionality, dense internal organization, mechanical performance will improve greatly; But its not enough one side is also arranged, as: add showing tremendous enthusiasm time manyly, its forging stock scaling loss is many, coal-firedly consumes manyly, and equipment dynamic consumption is many, and labor strength is big, and the final production cost is high.
In view of above its not enough one side; People are inquiring into the circular material blank with the bigger annular forging piece of casting process elder generation manufactured size always; It is the cast steel base; Replace or save the part operation in " after square steel is heated to the forging temperature, " operation in the free forging process, use " the once technology of heating and forging and molding (circular, square-section can) " just can produce the method for qualified forging again with cutting or chopping blanking, post bake, rammer cake, punching and three heating preforms; four times heating back finish-forging is shaped.But when in the discussion process, selecting conventional depanning amount of taper for use because of it, the annular inboard of its cast steel base and the lower mold body of mould be stuck can not separate together or on the base substrate section of cast steel base, be prone to crack or scrap in crack and forming.
The utility model content
The task that the utility model will solve provides a kind of assembling die of prefabricated annular forging piece cast steel base, and its structure has in the annular that can make the cast steel base successfully separates with lower mold body, on base substrate, does not crack or the crack simultaneously; Also can form the annular surface of the circular shape of a straight annular surface or a protrusion, also can be to constitute on the mold of the open die forging finish-forging forming technology that an ability carrying out subsequently or isoceles triangle annular skewed surface that can pinpoint protrusion on the mould of machine for rolling ring simultaneously, and the production cost of annular forging piece is reduced significantly in the annular inboard of base substrate in its annular inboard.
The technical scheme of the utility model is following: a kind of assembling die of prefabricated annular forging piece cast steel base, comprise lower mold body and inner ring body, and its lower mold body is the cake shape; An one of which end face is provided with recessed circular cylindrical cavity, and its inner ring body is arranged in the circular cylindrical cavity of lower mold body, and circular cylindrical cavity described with it constitutes an annular cavity; It is characterized in that; The bottom of the circular cylindrical cavity of said lower mold body is provided with recessed step, on said step, is evenly equipped with several pin-and-holes down, and said inner ring body is arranged in the recessed step; Said inner ring body is an annular; Be to constitute by little ring piece and little wedge combinations, the bottom surface of said little ring piece be provided with above-mentioned down pin-and-hole corresponding on pin-and-hole, between pin-and-hole and the following pin-and-hole bearing pin is housed on said.
The inner ring body of a combining structure is set in the die cavity of lower mold body, and this inner ring body is made up of little ring piece and little voussoir, and little ring piece and the little voussoir of forming inner ring body is respectively two, three, also can is four or more; Little ring piece and the contact surface between the little voussoir of forming inner ring body are that matching surface is the plane, still, all form the angle that promptly is set to separately between two matching surfaces on the little ring piece and between two matching surfaces on the little voussoir; The annular outer surface of inner ring body both can be set on promptly as the surface of die cavity straight annular surface, also can be set to recessed circular shape annular surface, can also be set to a recessed isoceles triangle skewed surface; And, when being provided with, need not consider the depanning gradient; Cavity bottom in lower mold body is provided with step, and its step can be confirmed and can be limited the position of inner ring body in the lower mold body die cavity.
When using this mould, as long as the inner ring body of combining structure is placed in the die cavity of lower mold body; And after the casting beginning, can lay down little voussoir; At this moment; Use hand hammer to knock out little voussoir on the inner ring body lightly and just can lay down little voussoir, this moment and just can make inner ring body lose applied external force and free shrink, just avoid the generation in crackle or crack, lay down little ring piece subsequently again or the lower mold body of overturning can be separated the cast steel base of annular forging piece with it.
List ton cost element and the utility model technical scheme that conventional free forging process forges the annular forging below; Earlier prefabricated cast steel base, carry out open die forging (or rolling) finish-forging, the reference table of the ton cost element correspondence comparison of its annular forging again with machine for rolling ring:
Figure BSA00000475840500031
The beneficial effect of the utility model is following: owing to adopt technique scheme, the belt inboard that has just reached its cast steel base can separate with lower mold body, has reached simultaneously on the base substrate of its cast steel base, not crack or the effect in crack; Also formed straight, that circular arc is a recessed or ability pinpoint recessed isoceles triangle annular skewed surface in the open die forging mold simultaneously in the base substrate inboard; Make the Forging Technology of carrying out subsequently simplify greatly; Production cost significantly reduces, and has realized the task of the utility model expection.Its method and structure is all simple.
