Abstract
The invention provides a semi-closed type tripod flange blank ejection technique which comprises the following steps of (1) feeding: selecting the specification length and diameter of materials according to forged products; (2) heating: selecting the magnetic pipe, current and heating frequency of a proper medium-frequency induction heating furnace; (3) preparing blanks; (4) preforging: preforging the prepared blank in a preforging die, and controlling the thickness of the forged piece; (5) final forging: controlling the related size of the forged piece according to the requirements of products; (6) shaping: performing punching, trimming and shaping on a hot forged piece through a trimming and punching and shaping combined die at a time; (7) post-processing: conducting shot blasting and inspection to the shaped forged piece, putting in storage to complete the production of the forged piece. According to the semi-closed type tripod flange blank ejection technique, a semi-closed blank ejection die replaces the flattening procedure, the utilization rate of materials can be improved, the filling of the forged piece can be ensured, and reject products can be completely eliminated; in addition, one procedure of the trimming and punching and shaping combined die replaces three procedures of punching, trimming and shaping, the quality of the forged piece can be guaranteed, operators can be reduced, and the energy consumption can be decreased.
Description
Technical field
The present invention relates to a kind of multiway bead forging, be specially the half-closed ejection technique of tripod bead.
Background technology
The tripod bead is forging on truck drive shaft, for vehicles such as Shanghai Volkswagen Tiguan.This product wall is thin and dark, and there are three branch pawls and boss in end, and sub-material is inhomogeneous, and the forging difficulty is larger.When tradition tripod bead is produced, multiplex open type is forged or the closed-die forging base.In open die forging, impressing forging production, the thin-walled depths can't be sufficient, and stock utilization is low, and learies is large; During the enclosed ejection, equipment pressure is large, and between branch pawl mouth, material, burr easily are pressed into forging and cause and scrap.
Summary of the invention
Technical problem solved by the invention is to provide a kind of tripod bead half-closed ejection technique, to solve the problem proposed in the above-mentioned background technology.
Technical problem solved by the invention realizes by the following technical solutions:
The half-closed ejection technique of tripod bead comprises the following steps:
(1) blanking: 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) heating: according to billet size, select magnetic tube, electric current, the heating frequency of suitable Medium Frequency Induction Heating Furnace;
(3) base: initial blank that heating is completed is injected and is semi-enclosedly gone out in mold, initial blank is subject to interior inflow of the downward model cavity of resistance of overlap bridge, then by be molded into and make initial blank grab top to three branches as much as possible flow to form just base, while in this operation, being molded into counterdie, leave gap between upper and lower mould;
(4) blocking: will make base and put into blocker and carry out blocking, and control the thickness of forging;
(5) finish-forging: pre-forging is put into to finisher and carry out finish-forging, according to product requirement, controlled the relevant size of forging;
(6) shaping: after finish-forging finishes, hot forging completes punching, trimming and shaping by edge-cutting and hole-punching shaping compound die is disposable;
(7) post-processed: forging will carry out ball blast, check after completing shaping, and warehouse-in, complete forging production.
beneficial effect
The present invention adopts and semi-enclosedly goes out mold and replace flattening process, has saved raw material 15%, has improved the utilization rate of material, and guarantees that forging fills, and has eliminated waste product; Use replaceable operation chain punching of edge-cutting and hole-punching shaping compound die, trimming and three operations of shaping simultaneously, guarantee the quality of forging, reduce operating personnel, at least two people's operations originally, only need people's operation now, reduces energy consumption.
The accompanying drawing explanation
To be that the tripod bead is half-closed go out the mold exploded view to Fig. 1;
Fig. 2 is the half-closed ejection lower die structure of tripod bead schematic diagram.
In figure: 1-patrix, 2-counterdie, 3-locating slot, 4-play repeated hole, the upper model cavity of 5-, 6, counterdie die cavity, 7-pressing plate groove, 8-jogger hole, 9-push rod groove, 10-overlap bridge, 11-overlap cavity, tri-branch's pawls of 12-.
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.
As shown in Figure 1-2, the half-closed ejection technique of tripod bead comprises the following steps:
(1) blanking: 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) heating: be heated to 1140o ℃-1160 ℃ in Medium Frequency Induction Heating Furnace;
(3) base: initial blank that heating is completed is injected and is semi-enclosedly gone out in mold, initial blank is subject to the interior inflow of the downward model cavity 6 of resistance of overlap bridge 10, then patrix 1 is pressed into and makes initial blank grab the mobile just base that forms in 12 tops to three branches as much as possible, the shut height of upper and lower mould is 3mm;
(4) blocking: will make base and put into blocker and carry out blocking, and control the thickness of forging;
(5) finish-forging: pre-forging is put into to finisher and carry out finish-forging, according to product requirement, controlled the relevant size of forging;
(6) shaping: after finish-forging finishes, hot forging completes punching, trimming and shaping by edge-cutting and hole-punching shaping compound die is disposable;
(7) post-processed: forging will carry out ball blast, check after completing shaping, and warehouse-in, complete forging production.
To those skilled in the art, obviously the invention is not restricted to the details of above-mentioned example embodiment, and in the situation that do not deviate from spirit of the present invention or essential characteristic, can realize the present invention with other concrete form.Therefore, no matter from which point, all should regard embodiment as exemplary, and be nonrestrictive, scope of the present invention is limited by claims rather than above-mentioned explanation, therefore is intended to include in the present invention dropping on the implication that is equal to important document of claim and all changes in scope.
