Abstract
The invention provides a longitudinal die locking structure of a large forging die. The longitudinal die locking structure can effectively prevent forge piece malposition in the die forging process due to movement of longitudinal lateral force and facilitate die release after forging. The longitudinal die locking structure comprises the die and a die seat, wherein the die is installed in the die seat. The longitudinal die locking structure is characterized by further comprising a jack, the jack is installed on the longitudinal outer side of the die seat, and an ejecting rod of the jack penetrates through the die seat along the longitudinal direction. When the die is longitudinally locked, the end face of an ejecting block of the end portion of the ejecting rod is flush with a longitudinal inner wall of the die seat, and a steel tape is filled between a longitudinal outer side wall of the die and the longitudinal inner wall of the die seat.
Description
Technical field
The present invention relates to the mounting technique field of large-scale forging die, be specially the longitudinal locking mechanism of mould of large-scale forging die.
Background technology
The longitudinal retaining mechanism of mould of existing large-scale forging die passes through push rod, hollow jackscrew and spring carry out flexible fastening to the mould be installed in die holder, see Fig. 1, thread bush 9 is threaded with die holder 4 by its external screw thread, and be threaded with hollow jackscrew 10 by its internal thread, hollow jackscrew and spring are all set in push rod outside, the end of push rod is provided with jacking block, hollow jackscrew is by spring pressure, there is spring 11 by push rod 12 through hollow jackscrew 10 and nut 13 pretension, push rod 12 locking die 6 is made by the hollow jackscrew 10 of turn, although this mechanism ensure that screw thread is not fragile, but there is mould and cause forging to misplace because of the play of longitudinal side force in forging process in it, and cause the phenomenon of carving iron locking mould, cannot the demoulding after causing forging.
Summary of the invention
For the problems referred to above, the invention provides the longitudinal locking mechanism of mould of large-scale forging die, it can effectively prevent from mould in forging process because of the play of longitudinal side force causing forging misplace, and is convenient to the demoulding after forging.
Its technical scheme is such, it comprises mould and die holder, described mould is installed in described die holder, it is characterized in that: it also comprises jack, described jack is installed on described die holder longitudinally outside, the push rod of described jack is longitudinally through described die holder, and when described mould is longitudinally locked, the end face of jacking block of described push rod end flushes with longitudinal inwall of described die holder, fills in steel band is housed between longitudinal lateral wall of described mould and longitudinal inwall of described die holder.
It is further characterized in that:
The jacking block of described push rod end is spacing by the limiting stand terrace of described die holder, and its end face is flushed with longitudinal inwall of described die holder;
Longitudinal lateral wall of described die holder is provided with jack bracket, and described jack is installed in described jack bracket.
Adopt the longitudinal locking mechanism of mould of the present invention, the jack being positioned at the longitudinal outside of die holder promotes push rod and is pushed into by mould and is close to the datum level of die holder longitudinal medial, then jack drives push rod retraction until the jacking block of push rod is by step confined planes longitudinal spacing, then jam-pack steel band between mould and die holder, namely the longitudinal direction locking of mould is completed, its beneficial effect is: it is by jack, steel band is by mould longitudinally locking, whole locking mechanism is made to be rigid fixation structure, structure is simple, easy to operate, thus can prevent mould from forging process, causing forging to misplace because of the play of longitudinal side force, it effectively can control the longitudinal magnitude of misalignment of forging within 1mm, and effectively can avoid the phenomenon of carving iron locking mould, ensure the smooth demoulding of the rear forging of forging.
Accompanying drawing explanation
Fig. 1 is the longitudinal locking mechanism schematic diagram of existing mold;
Fig. 2 is the longitudinal locking mechanism schematic diagram of mould of the present invention.
Detailed description of the invention
See Fig. 2, structure of the present invention comprises mould 6, die holder 4, jack 2, mould 6 is installed in die holder 4, jack 2 is installed on die holder 4 longitudinally outside, the push rod 3 of jack 2 is longitudinally through die holder 4, when mould 6 is longitudinally locked, the end face of jacking block 7 of push rod 3 end flushes with longitudinal inwall of die holder 4, while longitudinal lateral wall of mould 6 and the longitudinal inwall of die holder 4 between fill in steel band 5 be housed.Wherein, the jacking block 7 of push rod 3 end is spacing by the limiting stand terrace 8 of die holder 4, and jacking block 7 end face is flushed with longitudinal inwall of die holder 4, and the push rod 3 of jack 2 is by step confined planes 8 longitudinal spacing; Longitudinal lateral wall of die holder 4 is provided with jack bracket 1, and jack 2 is installed in jack bracket 1.
