Abstract
The invention discloses a novel closed type blank discharging technology of a thin-wall tendon deep upper opening narrow part. The novel closed type blank discharging technology includes the following steps that firstly, billets are manufactured, and raw bar materials with proper diameters are sawn and cut into the billets as required; secondly, medium frequency induction heating is performed and the billets are heated; thirdly, closed type blank manufacturing is performed, the initial billets undergo billet gathering and flattening forming in a cavity closed type blank discharging die so as to form a prefabricated blank, and resistance used for entirely closing the side wall of the closed die cavity and existing on the peripheries of a lower die and an upper die of the die in the process of forming the prefabricated blank forces the initial billets to fill the die cavity; fourthly, dummying is performed on the prefabricated blank; fifthly, finish forging is performed, the process of finish forging enables a dummying piece to deform continuously, and a qualified finish forging piece is obtained; sixthly, trimming is formed, and hot trimming and shaping are performed after finish forcing is finished. The novel closed type blank discharging technology of the thin-wall tendon deep upper opening narrow part can ensure that the initial billets are sufficient, the performance of the novel closed type blank discharging technology is ensured, and meanwhile the novel closed type blank discharging technology has the advantages of being low in production cost, good in forging quality and the like.
Description
Technical field
The present invention relates to the forging of dark local narrow the class suitable for reading of a kind of thin-walled muscle, be specially dark narrow the novel enclosed ejection technique suitable for reading of thin-walled muscle.
Background technology
The narrow plate class of thin-walled and dark middle place suitable for reading is mainly a kind of connector be used on caravan.Due to this series products thin-walled, base plate is thin, profile is irregular, aborning, the sub-material inequality often occurs, fills the not enough phenomenon of material, make to forge kind and be restricted.
Summary of the invention
Technical problem solved by the invention is to provide a kind of thin-walled muscle dark narrow novel enclosed ejection technique suitable for reading, to solve the problem proposed in the above-mentioned background technology.
Technical problem solved by the invention realizes by the following technical solutions:
Dark narrow the novel enclosed ejection technique suitable for reading of thin-walled muscle comprises the following steps:
(1) blank: according to the selected materials specification length of institute's forging product and diameter, suitable diameter raw material bar is sawed to material on request and block into blank;
(2) Frequency Induction Heating: according to billet size, select magnetic tube, electric current, the heating frequency of suitable Medium Frequency Induction Heating Furnace;
(3) enclosed base: initial blank is formed to prefabricated blank having the die cavity enclosed to go out in mold to gather material and flatten moulding, and in the base forming process, the counterdie of mould and patrix periphery exist the resistance of integrally closed to force initial blank to be full of mold cavity;
(4) blocking: by the pre-forging of prefabricated blank, in the blocker forging process, there is the overlap of integrally closed in pre-forging periphery, and the overlap be closed produces resistance, again forces the pre-forging of prefabricated blank to be full of mold cavity;
(5) finish-forging: pre-forging is put into to finisher and carry out finish-forging, the finish-forging operation makes pre-forging continue distortion, be full of die cavity, obtains qualified finish-forging part;
(6) trimming: finish-forging carries out hot trimming and shaping after finishing, and the excision overlap is controlled forging ' s block dimension simultaneously, makes forging ' s block dimension and precision reach designing requirement.
beneficial effect
Enclosed preforming of the present invention had both had advantages of closed-die forging technique, can forge and be applicable to common forging equipment as open type again, can on the ordinary hot drop press, realize One-time forging, forming process has increased the overlap resistance, initial blank is flowed to die cavity as much as possible, solve sufficient problem, guarantee its performance; There is production cost low, the advantage such as forging quality is good simultaneously.

The specific embodiment
Below in conjunction with the embodiment of the present invention, the technical scheme in the embodiment of the present invention is clearly and completely described, obviously, described embodiment is only the present invention's part embodiment, rather than whole embodiment.Embodiment based in the present invention, those of ordinary skills, not making under the creative work prerequisite the every other embodiment obtained, belong to the scope of protection of the invention.
Embodiment 1
As Figure 1-3, dark narrow the novel enclosed ejection technique suitable for reading of thin-walled muscle comprises the following steps:
(1) blank: according to the selected materials specification length of institute's forging product and diameter, suitable diameter raw material bar is sawed to material on request and block into blank;
(2) Frequency Induction Heating: according to billet size, select magnetic tube, electric current, the heating frequency of suitable Medium Frequency Induction Heating Furnace;
(3) enclosed base: initial blank is gone out in mold to gather material and flatten moulding to form prefabricated blank in the die cavity enclosed, in the base forming process, the counterdie 4 of mould exists the resistance of integrally closed mold cavity sidewall to force initial blank to be full of mold cavity with patrix 1 periphery, enclosed base mould mould structure as shown in Figure 1, comprise patrix 1, counterdie 4 and push rod 5, wherein patrix 1 is provided with patrix drift 2, and counterdie 4 is provided with counterdie die cavity 3; Patrix 1 and counterdie 4 are arranged on respectively on the upper bolster and die shoe of hot die forging press, and the interior push rod of jogger hole 5 is arranged on the bottom of counterdie die cavity 3, when mould is closed, between patrix and counterdie, leave the 0.5mm gap; During the prefabricated blank blocking, pre-forging presses down with patrix 1, produces overlap, and flows to outer rim, when encountering the wall on counterdie die cavity top, stops; While continuing to press down, patrix and counterdie form near closed hollow ring, and the resistance of sealing overlap increases gradually, until initial blank is full of die cavity fully; Base ejects the counterdie die cavity by the interior push rod of jogger hole 5 after finishing;
(4) blocking: prefabricated blank is carried out to blocking, in the blocker forging process, there is the overlap of integrally closed in pre-forging periphery, the overlap of sealing produces resistance, again forces the pre-forging of prefabricated blank to be full of mold cavity, and blocking ejects the counterdie die cavity by push rod by forging after finishing;
(5) finish-forging: the finish-forging operation makes pre-forging continue distortion and obtains qualified finish-forging part;
(6) trimming: finish-forging carries out hot trimming and shaping after finishing, and the excision overlap is controlled forging ' s block dimension simultaneously, makes forging ' s block dimension and precision reach designing requirement.
