The invention discloses valve deck forging molds, it is characterised in that: including main mould, pad mould and split pattern, main mould has a upper and lower mould chamber, and the split pattern is movably arranged at upper cavity, and by the module composition of several fissions, the pad mould is independently arranged split pattern in the bottom of main mould；When being forged to valve deck, the fixed length bar that outer diameter is slightly less than seperated cavity hole is put into valve deck forging mold, jumping-up is carried out to the upper end of fixed length bar first, it deforms bar upper end and fills up upper cavity, then valve deck forging mold is subjected to 180 degree steering, and removing pad mould keeps bar lower end exposed, then jumping-up is carried out to the lower end of bar, it deforms bar lower end and fills up lower mode cavity, the bar of both ends jumping-up and intermediate punching is finally exited into main mould, and split pattern is removed, then valve deck forging forms.The present invention can directly forge the U-type groove among valve deck, reduce forge weight and material loss, high production efficiency, scrappage is low, and saves subsequent machining cost.
Description
Technical field
The present invention relates to a kind of valve deck forging molds.
Background technique
For ball valve valve deck, generally by open die forging mode molded blank, the centre of valve deck has U-type groove, which wants
It is completed by machining, so the forge weight before processing is big, material loss is also big, while will increase processing cost；U-type groove
Also the rolling ring technique by ring rolls completes, this needs the configuration of rolling ring equipment and rolling ring mold, at high cost and uncomfortable
Small dimension valve deck is closed, moreover, rolling ring production efficiency is low, and product rejection rate is high, and workpiece will be warmed to when rolling ring
Very high temperature, energy loss are big.
Summary of the invention
In view of the deficiencies of the prior art, the purpose of the invention is to provide one kind can directly forge it is U-shaped among valve deck
Slot reduces forge weight and material loss, the valve deck forging mold of high production efficiency.
In order to solve the above technical problems, the present invention adopts the following technical scheme that complete:
Valve deck forging mold, it is characterised in that: including main mould, pad mould and split pattern, main mould has upper and lower mould chamber, the chamber of upper cavity
Pore size is greater than the lumen pore size of lower mode cavity, and the split pattern is movably arranged at upper cavity, split pattern by several fissions module structure
At the seperated cavity hole less than lower mode cavity lumen pore size, the bottom of split pattern and upper mold are crossed between the module of each fission jointly
The bottom of chamber of chamber is in contact, and the pad mould is independently arranged in the bottom of main mould；When being forged to valve deck, outer diameter is slightly less than point
The fixed length bar of body cavity hole is put into valve deck forging mold, carries out jumping-up to the upper end of fixed length bar first, becomes bar upper end
Shape simultaneously fills up upper cavity, and valve deck forging mold is then carried out 180 degree steering, and removing pad mould keeps bar lower end exposed, then
Jumping-up is carried out to the lower end of bar, bar lower end is deformed and fills up lower mode cavity, followed by making valve to being punched out among bar
The bar of both ends jumping-up and intermediate punching is finally exited main mould, and removes split pattern by hole forming in covering, then valve deck forging at
Type.
After adopting the above technical scheme, the present invention can directly forge the U-type groove among valve deck, concrete operating principle is: will
The fixed length bar that outer diameter is slightly less than seperated cavity hole is put into valve deck forging mold, carries out jumping-up to the upper end of fixed length bar first,
It deforms bar upper end and fills up upper cavity, bar upper surface is slightly higher than upper cavity, and valve deck forging mold is then carried out 180 degree
It turns to, and removing pad mould keeps bar lower end exposed, then carries out jumping-up to the lower end of bar, bar lower end is made to deform and fill up down
Die cavity, bar lower end surface are slightly higher than lower mode cavity, followed by hole forming in valve deck is made to being punched out among bar, finally by both ends
The jumping-up and bar for going out inner hole exits main mould, and split pattern is removed, the then valve deck forging molding of Intermediate Gray U-type groove.Due to
The U-type groove among valve deck is directly forged, so reducing forge weight and material loss, high production efficiency, scrappage is low, and saves
Subsequent machining cost is applicable in the valve deck forging molding of small dimension valve deck and small batch.
Preferably, seperated module composition of the split pattern by three pieces of identical sizes.
Attached drawing is said
The present invention has following attached drawing:
Fig. 1 is the structural diagram of the present invention,
Fig. 2 is the top-direction view of Fig. 1,
Fig. 3 is the forging technology flow chart of valve deck.
Specific embodiment
As shown in Figure 1, 2, valve deck forging mold of the invention, including main mould 1, pad mould 3 and split pattern 2, main mould 1 have upper
Lower mode cavity, the lumen pore size of upper cavity 11 are greater than the lumen pore size of lower mode cavity 12, and the split pattern 2 is movably arranged at upper cavity 11,
Split pattern 2 is crossed jointly less than 12 chamber of lower mode cavity between the module of each fission by three pieces of seperated module compositions of identical size
The bottom of the seperated cavity hole 21 of pore size, split pattern 2 is in contact with the bottom of chamber of upper cavity 11, and the pad mould 3 is at the bottom of main mould 1
Portion is independently arranged；The lumen pore size of upper cavity 11 is identical as the excircle dimension of part in forged valve deck U-type groove, upper cavity 11
Height is slightly less than the height dimension of part in forged valve deck U-type groove, the lumen pore size of lower mode cavity 12 with the difference in height of split pattern 2
Identical as the excircle dimension of part under forged valve deck U-type groove, 12 height of lower mode cavity is slightly less than part under forged valve deck U-type groove
Height dimension, the height dimension of split pattern 2 is equal to the height of forged valve deck U-type groove, and the aperture of seperated cavity hole 21 is equal to
The groover rot diameter of forged valve deck U-type groove.
As shown in figure 3, valve deck forging mold of the invention, when forging to valve deck, process is as follows: a step, will be outer
The fixed length bar that diameter is slightly less than seperated cavity hole 1-2mm is put into valve deck forging mold；B step carries out the upper end of fixed length bar
Jumping-up deforms bar upper end and fills up upper cavity, and bar upper surface is slightly higher than upper cavity；Step c, by valve deck forging mold into
Row 180 degree turns to, and removing pad mould keeps bar lower end exposed；Step d carries out jumping-up to the lower end of bar, becomes bar lower end
Shape simultaneously fills up lower mode cavity, and bar lower end surface is slightly higher than lower mode cavity；Step e makes hole forming in valve deck to being punched out among bar；
F step, by both ends jumping-up and the bar of going out inner hole exits main mould, and removes split pattern, then the valve deck forging of Intermediate Gray U-type groove
Part molding.
