Description
Technical field
The utility model relates to a kind of mould, is specifically related to a kind of gear ring blank shaping mould.
Background technology
Chinese invention patent ZL200610095226.X, patent name are the technical process that blank processes gear ring blank for automobile synchronizer for " a kind of method of processing automobile synchronized gear ring blank " discloses a kind of with the bar steel, by operations such as blanking, heating, descale, jumping-up, punching, blanking planar end surface, extension forming and shapings, it is 50～78mm that the bar steel are processed into internal diameter, wall thickness is 10～15mm, highly is the finished product gear ring blank of 45～60mm.The present invention will roll over the ring process technology and be applied in the processing of gear ring blank for automobile synchronizer, greatly reduced the manufacturing cost of blank, improved the accuracy of manufacture of blank, improved fabricated part heat treatment performance, reduced follow-up machining allowance, improve production efficiency, prolonged the service life of finished product gear ring.
It is for the ovality that reduces gear ring blank, the circularity that improves inside and outside circle that above-mentioned gear ring blank process increases the shaping step.At present, the employed shaping mould of this technology is a monoblock type, the problem that this monoblock type mould runs in actual production process has: the gear ring blank of different size needs different moulds, and the description of gear ring blank is various, cause the quantity of mould many, monoblock type mould volume is big, and the mould occupation space of not loading onto lathe is big, causes parking space wasteful; When needing to change after the die wear, the monoblock type mould is an integral replacing, has increased die cost; In addition, when mould had local defect to repair, the monoblock type mould was big because of volume, weight is big, was not easy to processing and handled, and maintenance time is long.
The utility model content
Technical problem to be solved in the utility model just provides a kind of parking space and takies the gear ring blank shaping mould little, that cost is low, easy to maintenance.
Technical problem to be solved in the utility model is to realize by such technical scheme, it includes die holder and core rod combination, die cavity is arranged at the top of described die holder, the die cavity bottom is provided with material-dropping hole, the core rod combination is installed in the die cavity of die holder, the core rod combination is provided with die cavity straight down, die cavity that this core rod makes up and the corresponding connection up and down of the material-dropping hole of die holder.
As further improvement of the utility model: above-mentioned core rod combination can comprise die lower cover, core rod and die loam cake, the bottom of core rod places in the end face recess of die lower cover, the bottom surface recess of die loam cake is buckled in the top of core rod, two or more screws pass the die lower cover from the die loam cake, and the core rod combination is fastened on the die cavity bottom surface of die holder.
Occupation mode of the present utility model is: after installing mould on the press machine, red-hot gear ring blank is placed the die cavity top of the utility model core rod combination, start the power set of press machine, drift is moved downward, drift is pushed down gear ring blank, make gear ring blank stressed along die cavity to lower slider, the cylindrical of gear ring blank is subjected to mould intracavity wall extruding to produce distortion, thereby makes the gear ring blank cylindrical consistent with die cavity.The gear ring blank of being pushed down by drift passes die cavity from top to down, in the material-dropping hole of die holder drops product container below lathe, thereby finishes the shaping of gear ring blank.
Because shaping mould is decomposed into die holder and core rod combination two parts, and die holder is the sharing body of all moulds, by changing the specification of core rod combination, can constitute different moulds to adapt to various specification gear ring blank processing, can reduce the parking space of mould like this.Because parts easy to wear are the parts of core rod combination or core rod combination in the mould, more mold exchange only need be changed the parts of core rod combination or core rod combination, greatly reduces the cost of mould.When core rod combination defectiveness needed repairing, the parts that only need hold defective went maintenance, and specific volume is little, in light weight mutually with mold integral for these parts, the convenient repairing.The utlity model has following advantage: parking space takies little, and cost is low, and is easy to maintenance.

Among the figure: 1. die holder; 11. die cavity; 12. material-dropping hole; 2. core rod combination; 21. die lower cover; 21a. end face recess; 22. core rod; 23. die loam cake; 23a. bottom surface recess; 24. die cavity; 3. screw; 4. drift; 5. gear ring blank.
The specific embodiment
The utility model is described in further detail below in conjunction with drawings and Examples:
As shown in Figure 1 and Figure 2, the utility model includes die holder 1 and core rod combination 2, die cavity 11 is arranged at the top of described die holder 1, the die cavity bottom is provided with material-dropping hole 12, core rod combination 2 is installed in the die cavity 11 of die holder 1, core rod combination 2 die cavitys 24 that are provided with straight down, the die cavity 24 of this core rod combination 2 and material-dropping hole corresponding connection about in the of 12 of die holder.
The occupation mode of this mould is as shown in Figure 6: after installing mould on the press machine, red-hot gear ring blank 5 is placed die cavity 24 tops of the utility model core rod combination 2, start the power set of press machine, drift 4 is moved downward, drift 4 is pushed down gear ring blank 5, make gear ring blank 5 stressed along die cavity 24 to lower slider, the cylindrical of gear ring blank 5 is subjected to the extruding of die cavity 24 inwalls to produce distortion, thereby makes gear ring blank 5 cylindricals consistent with die cavity 24.The gear ring blank of being pushed down by drift 5 passes die cavity 24 from top to down, in the material-dropping hole 12 of die holder 1 drops product container below lathe, thereby finishes the shaping of gear ring blank 5.
As Fig. 1, Fig. 3, Fig. 4 and shown in Figure 5, core rod combination 2 comprises die lower cover 21, core rod 22 and die loam cake 23 again, the bottom of core rod 22 places in the end face recess 21a of die lower cover 21, the bottom surface recess 23a of die loam cake 23 is buckled in the top of core rod 22, two or more screws 3 pass die lower cover 21 from die loam cake 22, and core rod combination 2 is fastened on die cavity 11 bottom surfaces of die holder 1.
Like this, because core rod combination 2 further is decomposed into die lower cover 21, core rod 22 and die loam cake 23 3 parts, die lower cover 21 and die loam cake 23 are set model, as the sharing body of this model, under certain model of determining, by changing the specification of core rod 2, just constitute multiple concrete mould specification, realize further reducing the mold storing space, it is low to reduce cost, easy to maintenance.
As Fig. 1, Fig. 4, shown in Figure 5, the outward-dipping formation expansion of die cavity 24 upper inside wall of core rod combination 2 opening is convenient to place gear ring blank when process operation.
Die cavity 11 inwalls of the utility model die holder 1 and core rod make up between 2 outer walls and leave the gap, so that punch press adds man-hour, make up 2 stressed expansions towards periphery to core rod and leave the space, avoid die holder 1 to be hit for a long time and rupture.
