The upper sidling plate is fixedly installed on an automatic necking pressure machine, and is coaxially provided with the adjusting rod in a threaded meshing manner, the adjusting rod is installed on the upper sliding plate by an upper lock nut and a lower lock nut, the necking die is coaxially installed at the lower end of the adjusting rod, and a cavity of the necking die is shaped like a bowl with opened lower part. the multi-pass necking mould for the thin-wall shaped cylindrical piece has simple structure manufacturing, scientific and reasonable design and convenient installation and use, effectively guarantees the multi-pass necking quality of the thin-wall shaped cylindrical piece, and particularly suitable for necking processing on various thin-wall cylindrical pieces.
Description
Technical field
The utility model belongs to field of machining, relates in particular to a kind of thin-wall special-shaped cylindrical member multi-pass reducing mould.
Background technology
Thin-wall special-shaped cylindrical member is an aluminium material, because its light weight, relative intensity are lower, when multi-pass reducing pressure processing, if mould is bad, very easily causes the workpiece buckling deformation, makes the thin-wall tube-shaped element bottom produce distortion, even scraps; In addition, the height dimension coherence request of thin-wall special-shaped cylindrical member is higher.Especially thin-wall special-shaped cylindrical member exists serious " unstable phenomenon " when carrying out the multi-pass reducing, and the subject matter that overcomes " unstable phenomenon " is exactly the Mould design problem.Existing reducing mould design all can't overcome the problems referred to above.
By retrieval, do not find the open source literature that addresses the above problem yet.
Summary of the invention
The purpose of this utility model is to overcome the deficiencies in the prior art, a kind of thin-wall special-shaped cylindrical member multi-pass reducing mould is provided, this mould structure is made simply, design science is reasonable, easy to use, the life-span is longer, and can effectively improve thin-wall special-shaped cylindrical member in crudy of carrying out the multiple tracks reducing and stability.
The purpose of this utility model is achieved in that
A kind of thin-wall special-shaped cylindrical member multi-pass reducing mould, comprise that slide unit, adjusting lever, die holder, reducing die constitute, upper slide is packed on the automatic reducing forcing press, adjusting lever is installed in the coaxial threaded engagement on upper slide, the locknut location and installation was on upper slide under adjusting lever reached by last locknut, the coaxial installation reducing die in the adjusting lever lower end, the die cavity of this reducing die is that under shed is bowl-shape.
And described locknut down descends the locknut locking by the anti-rotation pressing plate.
And, the described coaxial installation reducing die of lock tube that passes through in the adjusting lever lower end.
Advantage of the present utility model and beneficial effect are:
1, this mould adopts ordinary steel (45
#) material and after machined is made, assembling is installed on the last slide unit of automatic reducing forcing press, during work, under the cooperation of necking machine automatically and special fixture, finishes reducing automatically and operates, and uses when being specially adapted to various thin-wall tube-shaped element automated production.
2, this mould has effectively overcome the workpiece unstable phenomenon when thin-wall tube-shaped element is carried out the reducing of multi-pass pressure, and necking force dropped to minimum, helped improving the qualification rate of workpiece after the reducing of thin-wall tube-shaped element multi-pass, guarantee the thin-wall tube-shaped element bottom smooth, do not have distortion, a height dimension unanimity.
3, the utility model structure fabrication is simple, design science is reasonable, and is easy to install, can guarantee effectively that thin-wall special-shaped cylindrical member carrying out multi-pass reducing quality, be a kind of novel multi-pass reducing mould structure, be specially adapted to various thin-wall tube-shaped elements and carry out reducing and add and use man-hour.
Description of drawings
Fig. 1 is the utility model workpiece blank schematic diagram;
Fig. 2 is the utility model processed workpiece structural representation (Hu Zui analyses and observe);
Fig. 3 is the structure scheme of installation of the utility model mould.
The specific embodiment
The utility model is described in further detail below in conjunction with accompanying drawing and by specific embodiment, and following implementation example is descriptive, is not determinate, can not limit protection domain of the present utility model with this.
The thin-wall special-shaped cylindrical member that the utility model is related is meant by thin-wall special-shaped cylindrical member 1 shown in Figure 1 and is processed into as shown in Figure 2 the shape with kettle mouth 2 and kettle body 3, and present embodiment is to be that example is described with the portable kettle of aluminum.
The described thin-wall special-shaped cylindrical member of present embodiment is meant that the kettle body of kettle is flat special-shaped shape.
A kind of thin-wall special-shaped cylindrical member multi-pass reducing mould is installed on the automatic reducing forcing press, and this forcing press is this area used hydraulic press usually.This mould comprises slide unit 5, adjusting lever 8, die holder 9, reducing die 10, upper slide is packed on the automatic reducing forcing press, adjusting lever is installed in the coaxial threaded engagement on upper slide, adjusting lever is by last locknut 4 and locknut 6 location and installation are on upper slide down, and following locknut is by 7 times locknut lockings of anti-rotation pressing plate; By lock tube 11 coaxial installation reducing dies, the die cavity of this reducing die is that under shed is bowl-shape in the adjusting lever lower end.
The adjusting lever lower end by the structure of the coaxial installation reducing die of lock tube is:
The reducing die upper end is shaped on an annular boss and setting-in is gone in the adjusting lever lower end, the top, upper end of lock tube is contained on the annular boss of reducing die, its outer rim is by screw-threaded engagement mode and the made screw-threaded engagement of adjusting lever lower end inner edge, finishes the coaxial installation of reducing die and adjusting lever thus.
Using method of the present utility model is:
Thin-wall special-shaped cylindrical member workpiece is installed in the reducing die, and the n mold is driven by automatic reducing forcing press, carries out the multistation circulation, and guarantees the positioning accuracy of mould.
Automatically the reducing forcing press up/downlink cycle once, promptly finish n=1 reducing, recycle once, promptly finish n=2 reducing; So circulation when n reducing reaches dimensional requirement, enters the pickup operation until workpiece this moment, finishes the reducing operation of single-piece workpiece.And so forth, but then continuous operation.
Processing step of the present utility model is:
One, calculates definite rational necking coefficient and reducing passage (seeing Table 1).
Two, designing and calculating is determined reducing mold structure parameter and running parameter (seeing Table 2).
Three, by the aforementioned calculation result, design, manufacturing reducing mould (see figure 2).
Table 1 necking coefficient and reducing passage calculation of parameter (example one)
Example: it is 2mm that a wall thickness is arranged, and diameter is the tubular aluminium matter workpiece of Φ 80mm (M=0), requires reducing to Φ 50mm, calculates the necking coefficient m that determines to need to use reducing passage n and each passage
iWith the diameter d after each passage reducing
i
The tabulation of table 1 result of calculation
Table 2: reducing mould working chamber structural design and running parameter (example two)
On connect (example one) application example.According to specified criteria M=0, and establish R=40, α=30 °, according to the mapping of Fig. 2 mould structure (seeing the mapping example for details).Each main structure parameters design result of calculation is as follows among the figure:
Illustrate: the semi-cone angle that preceding 3 passage R curves form is less than α, thus save (4 Δ i, LB ' 1-3) LB ' 1-3, A ' C ' 1-3, HA ' 1-3, ask for.
