Description
Technical field
The present invention relates to metal forming fields, more particularly for the quiet disk of new-energy automotive air-conditioning compressor
Manufacturing process and shaping dies.
Background technique
Scroll compressor has many advantages, such as compact-sized, energy-efficient, micro-shake and low noise and reliable operation, is widely used in
The air-conditioning device of new-energy automobile, scroll plate are the core components of scroll compressor, are divided into Moving plate and quiet disk, forming quality
Quality be directly related to air conditioning for automobiles and can work normally.
The quiet disk of traditional scroll plate does not have outer ring, and the only consistent vortex of height is placed on pedestal, sound disk phase interworking
Conjunction is placed in compression case body.Common processing method has gravitational casting, liquid forging, machining, low pressure casting and back pressure
Squeeze etc..Wherein gravitational casting and liquid forging production efficiency are lower；Not only production efficiency is low for machining, but also material use
Rate is low, higher cost；Low pressure casting is also easy to produce the internal flaws such as stomata, and product rejection rate is high and product mechanical performance is poor；Base
There is good mechanical property, high production efficiency, material benefit in the part that the back pressure extrusion process of flow-controlled forming technology shapes
With rate height, the advantages such as forming defects are few, product rejection rate is low, the technology is widely used in foreign countries, and the country also starts gradually
Using.
For the novel scroll disk of new-energy automobile, quiet dribbling as shown in Figure 4 has with certain altitude and thickness
Quiet disk outer ring 32, the height for being in the vortex 31 at middle part are lower than the height of quiet disk outer ring 32, are passed with the quiet substitution of disk outer ring 32
The compressor housing of system realizes that quiet disk is integrated with compressor housing, can greatly reduce the weight of compressor in this way, more accord with
Close energy-saving and environment-friendly requirement.Since the height and thickness of quiet disk outer ring are all larger than the vortex body portion at middle part, one is squeezed in back pressure
When secondary forming, the vortex metal flow rates at middle part are fast, and quiet disk outer ring metal flow rates are slow, on the one hand lead to quiet disk outer ring
Height be difficult to meet the requirements, on the other hand after vortex Partial Height reaches requirement, metal initially forms overlap at this, leads
It causes finish-forging cavity plate vortex throughhole portions stress increased dramatically, is easy to happen fracture failure, this situation has seriously affected quiet disk
Forming quality and mass production.

As shown in Figure 1, in the present embodiment Preform Die be blocking punch-pin 2 is fixed on using blocking punch-pin retainer plate 3 it is pre-
The bottom surface of upper die holder 1 is forged, blocking cavity plate 4 is placed in blocking cavity plate lasso 5, and blocking cavity plate cushion block 6 is placed in the type chamber of blocking cavity plate 4
In, blocking knockout rod 7 runs through blocking lower die holder 8 and blocking cavity plate cushion block 6.
When blocking shapes, the blank handled well is put into blocking cavity plate 4, is placed on blocking cavity plate cushion block 6, blocking is convex
2 downlink extrusion billet of mould, metal flow up, the anti-outer ring for squeezing out certain altitude, after forming, 2 uplink of blocking punch-pin, in advance
Forging ejector beam 7 ejects upwards under press hydraulic cylinder effect, by the die cavity of pre- forging ejection blocking cavity plate 4.
As shown in Fig. 2, the finish-forging upper mold in the present embodiment in finish-forging die is that finish-forging punch-pin 10 is passed through finish-forging punch-pin
Retainer plate 11 is fixed on the bottom surface of finish-forging upper die holder 9；Running through in finish-forging punch-pin 10 has knockout rod 28, and has expeller 29 can
It is butted on knockout rod 28；Mold is placed in lower die-sleeve 26 under finish-forging in finish-forging die, and die sleeve pressure is provided at the top of lower die-sleeve 26
Plate 27, the finish-forging cavity plate 14 in lower mold are placed in cavity plate lasso 15, and it is logical that the cavity bottom of finish-forging cavity plate 14 is provided with spiral
Hole, the shape of spiral through-hole is consistent with the shape of vortex in the middle part of quiet disk, and finish-forging cavity plate backing plate 16 is located at finish-forging cavity plate 14
With the bottom of finish-forging cavity plate lasso 15；The structure type for the back pressure apparatus being arranged in finish-forging die is: back pressure body 25 is located at eventually
In the cavity bottom spiral through-hole for forging cavity plate 14, the bottom of back pressure body 25 is provided with back pressure mandril 24, and back pressure mandril 24 is through eventually
Forging cavity plate backing plate 16 is placed in the top surface of spring bearer plate 18, and the bottom surface of spring bearer plate 18 is provided with ejector beam 20 in T-shape；Dish-shaped bullet
Spring 23 is placed in spring spool 19, spring bearer plate 18 is arranged at the top of disk spring 23, spring bearer plate 18 is placed in pressing plate lasso
In 17, the bottom of disk spring 23 is provided with spring backing plate 22, spring backing plate 22 is placed on finish-forging lower die holder 21, under finish-forging

To.
When finish-forging shapes, the metal flow rates of intermediate vortex part are greater than the flowing velocity of outer ring metal, when blocking at
The outer ring that shape goes out has certain guiding role, and the flowing velocity of metal can be improved, and reasonable outer ring height makes outer ring and whirlpool
Rotation body portion reaches forming height simultaneously substantially.The blank that blocking is obtained is put into finish-forging cavity plate 14,14 downlink of finish-forging cavity plate
Extrusion blank, since blank diameter is less than the diameter of quiet seat 33 of trying to get to the heart of a matter, a part of metal transverse flow in blank bottom when squeezing
Dynamic forming pedestal 33, a part of metal, which flows downward, shapes vortex body portion and quiet disk outer ring.The metal flow of vortex body portion
Unevenly, middle section metal flow is very fast, takes the lead in contacting back pressure body 25, back pressure body 25 is downward by back pressure mandril 24 after being pressurized
Squeeze spring bearer plate 18,23 forced compression of disk spring, to generate upward back pressure and act on the vortex portion of blank
Point, so that the height of 31 part of vortex is gradually reached unanimity.Finish-forging cavity plate 14 and back pressure body 25 make outer ring form an occlusion type
Chamber, the outer ring guidance metal with certain altitude that blocking obtains flows downward, when the sand off of outer ring, vortex body portion also base
Originally reach predetermined altitude, to guarantee that outer ring and vortex body portion reach object height, and end face is smooth.Forming terminates
Afterwards, finish-forging punch-pin 10 moves upwards, if forging stays on finish-forging punch-pin 10, hydraulic cylinder acts on expeller 29, makes knockout rod 28
It moves downward, forging is released, expeller 29 resets later, and knockout rod 28 returns to initial position in forming next time；If forging
It stays in finish-forging cavity plate 14, finish-forging ejector beam 20 ejects upwards under the action of hydraulic cylinder, passes through spring bearer plate 18 and back pressure body
Forging is ejected finish-forging cavity plate 14 by 25, while disk spring 23 resets, and discharges elastic force.
