Description
Technical field
The utility model relates to a kind of water meter case forge dies, and being particularly used for one kind may be mounted at forging machine tool
On, will disposably red copper rod be burnt and strike out the forge die of water meter case with forging machine tool.
Background technique
Water meter is to record the instrument of water consumption by measuring originally water flow, mainly includes water meter case (also referred to as table
Body) with water meter movement and housing, water meter case is generally made of metallic copper, is generally used casting and forming, is preferably used
Forging and forming.Water meter movement is arranged in the cavity of water meter case, the two sides of water meter case be respectively equipped with through the cavity into
Aquaporin and exhalant canal, are connected with waterpipe respectively.
Current market sales of water meter case mainly uses casting technique to form, and casting technique water meter case blank is being cast
Cause the exhausted air quantity generated when type larger, and blank shell wall is also easy to produce spilehole in casting process, two after need to being machined
Secondary infiltration could control part shell wall spilehole, and the whole learies generated by spilehole of blank are more, and this blank shell wall is close
Envelope property and entire shell mechanical strength want difference, have risk of breakage, and the inside and outside sight out-of-flatness of shell under high intensity collision, table
Face is coarse to be not achieved appearance requirement, can also generate certain influence to watermeter flowing rate stationarity after machine-shaping.
The document of few hot forging pressure technique water meter case disposable forge moulding technologies and Tool and Die Technology in the prior art
Report.Only have individual producers at present and water meter case is manufactured using hot Forging Technology and mold, but loses it and be hot-forged pressing element body technology
The detailed literature of step and mold specific structure is reported.Moreover, according to known to applicant in this case, water meter case and its water-in and water-out
Mouth still can not a punching press forming through holes, it is subsequent need to a large amount of machinings carry out water meter case molding.Since water meter case shape is special
Not, and intake-outlet needs core pulling, the mould structure design difficulty of disposable thermal forging and forming is very big, and molding structure design is difficult

The driving box 33 of 31 top of wall, the jumper bar 34 extended downwardly from driving box 33.The utility model water meter case forge die 30 is solid
Dingan County is in work stage 32.Crossbeam 35 is set below mold 30,35 both ends of crossbeam are arranged connecting rod 36 and connect driving box 33,
Driving box 33 drives jumper bar 34, crossbeam 35, connecting rod 36 to synchronize and move up and down.Setting top stick 37 in the middle part of crossbeam 35, top stick 37 have
There is operating position A being aligned with the mandril 7 of a mold 30 and off-position B.Sliding slot 40, top are set in the middle part of crossbeam 35
37 lower end of stick is inserted in sliding slot 40, and can be slided in sliding slot 40, the both ends of sliding slot 40 respectively be top 37 operating position A of stick with
Off-position B.Fluid pressure drive device 38 is additionally provided in the middle part of crossbeam 35.Returning spring 39 is set in top 37 side of stick, pushes up stick
37 when being moved to operating position A by off-position, since it is a non-loaded empty stick, is pulled to by returning spring 39
Operating position.And when pushing up stick and being moved to off-position by operating position, since it has 30 mass loading of mold above, by hydraulic
Driving device 38 drives it to be moved to off-position B by operating position, during which, 39 Tensile of returning spring；Once hydraulic coupling
It disappears, i.e., operating position A is returned to by multiple spring 39.Formed punch 6 is fixedly mounted on the lower end of jumper bar 34.
As shown in figure 9, the utility model water meter case forge die 30 is fixedly mounted in work stage 32, original state
To mold state, die holder 8 is fitted into mould bases 2 in chamber 9, and 8 upper surface of die holder and the upper surface of mould bases 2 are excessively neat, 5 upper surface of mold core
Relatively low because being crushed below fixed ring 22 thickness value of fixed ring 22, mold core 5 forms entire water meter case after merging
15 type chamber 13 and the entire punching 14 poured for formed punch 6；The top stick 37 at 35 middle part of crossbeam is in be aligned with the mandril 7 of mold 30
Operating position A.Red copper rod will be burnt to be put into punching 14, start forging machine tool, formed punch 6 follows jumper bar 34 to pour punching 14,
Red copper rod is burnt under 6 forceful action of formed punch by setting 13 disposal molding of type chamber of entire water meter case 15 into water meter case
15.Subsequent forging machine tool backhaul, formed punch 6 follow jumper bar 34 to reply upwards, and top stick 37 is pulled with crossbeam 35 by connecting rod 36 also same
Step is replied upwards, and the top docking mandril 7 of stick 37 pushes die holder 8 and is moved upward to through the first of chamber 9 through sliding slot 10 along mould bases 2
Die opening state position, the core-pulling slide block 4 being inlaid in 8 notch 18 of die holder also and then run through sliding slot through the second of chamber 9 along mould bases 2
11 are moved upward to die opening state position, and since mould bases 2 is up big and down small through 9 bore of chamber, the side wall through chamber 9 is inclined wall,
The process of moving up is the process that die holder 8 and mold core 5 open, and the process of moving up is mounted on the core pulling stick of 4 inside of core-pulling slide block
20 synchronize to be displaced outwardly and complete core pulling action, and die opening state die holder 8 and the core-pulling slide block 4 being inlaid in 8 notch 18 of die holder are high
Mould bases 2 out, die holder 8 and mold core 5 are in open configuration.At this moment, it is convenient to take out molding 15 workpiece of water meter case.
Take out 15 workpiece of water meter case after, starting fluid pressure drive device 38 by push up stick 37 be moved to off-position, at this moment, top stick 37 with
Mandril 7 cuts little ice, and runs through the first of chamber 9 along mould bases 2 respectively under die holder 8 and its each comfortable Gravitative Loads of core-pulling slide block 4
After initial molding state position is moved downward to through sliding slot 11 through sliding slot 10 and second, fluid pressure drive device 38 is closed,
Hydraulic coupling disappears, and pushes up stick 37 by multiple spring 39 and is returned to operating position A.This completes the one of 15 workpiece of water meter case
The secondary property forging and forming course of work.
