Description
Technical field
The utility model belongs to field of mechanical technique, relates to a kind of mfg. moulding die, and particularly a kind of compressor is with potassium steel balance weight mfg. moulding die.
Background technology
Most compressor of air conditioner generally all is to adopt rolling piston compressor, and the bent axle of rolling piston compressor all is eccentric the design, can cause the vibration of compressor in the running and produce noise.Therefore, generally balance weight all is installed, the imbalance that produces when turning round with bucking-out system at the two ends of compressor drum.
Traditional balance weight all is to adopt brass to process, and the proportion of brass is big, electromagnetic induction is also less, and the balance block structure of making is also comparatively compact.In recent years,, cause making the required cost of balance weight and also increase, thereby lower-cost low magnetic or the potassium steel that do not have magnetic just become the substitution material of making balance weight along with the rising of international copper valency.Its manganese content of potassium steel that hangs down magnetic or do not have magnetic is generally greater than more than 13%, and intensity is higher, adds very easily to produce sclerosis man-hour, and the potassium steel part mostly adopts casting usually, but the precision of casting can't reach the balance weight requirement that compressor of air conditioner is used.Therefore, the mould that is used to make the potassium steel balance weight just becomes the focus of research.
The mould of existing potassium steel balance weight all is to adopt the monoblock type mould.Such mould is poor because of material flowability when making the potassium steel balance weight, can only adopt closed moulding, and the suffered extruding force of mould is bigger, and service life is shorter.In addition, this mould is bigger because of the extruding force that receives, and for the mould that guarantees potassium steel does not ftracture, all is to adopt the mould steel of high strength, high-wearing feature to process, and comparatively heavy, required cost is also higher.
Summary of the invention
The purpose of the utility model is to have the problems referred to above to existing technology, has proposed a kind ofly can offset extruding force, and bearing capacity is good, and the compressor of long service life is with potassium steel balance weight mfg. moulding die.
The purpose of the utility model can realize through following technical proposal: a kind of compressor is with potassium steel balance weight mfg. moulding die; It is characterized in that; This mould comprises the formwork that the cylindrical core rod of profile is outer with being set in core rod; Be provided with between described formwork and the core rod and be arranged with the middle transition cover, be interference fit between described middle transition cover and core rod and middle transition cover and the formwork.
This compressor adopts multilayer architecture with potassium steel balance weight mfg. moulding die, is interference fit between middle transition cover and core rod and middle transition cover and the formwork, thereby can produces erection stress to core rod.During the moulding of potassium steel balance weight; The extruding force major part that during material deformation the core rod inwall is produced can be assembled stress and offset; Thereby improved the bearing capacity of mould widely, also increased substantially the life-span of mould simultaneously, entire die also needn't be made very heavyly.
Above-mentioned compressor with potassium steel balance weight mfg. moulding die in, the intensity of described middle transition cover is lower than the intensity of core rod, the intensity of formwork is lower than the intensity of middle transition cover.This compressor is to adopt multilayer architecture with potassium steel balance weight mfg. moulding die, and core rod is directly directly to contact with high manganese steel material, and the extruding force and the slippage that receive are bigger.Therefore this compressor mainly adopts the mould steel of high strength, high-wearing feature to process with the core rod of potassium steel balance weight mfg. moulding die.And extruding force and slippage that the middle transition cover is born are less relatively; The main not good enough a little mould steel of intensity that adopts is processed; Outmost formwork adopts the general structural alloy steel of intensity to process, thereby has reduced production cost greatly because of its suffered extruding force and slippage minimum.
Above-mentioned compressor with potassium steel balance weight mfg. moulding die in, in described middle transition cover comprises cover and be set in the outer overcoat of cover, between described overcoat and the interior cover and overcoat and formwork and described interior overlap and core rod between be interference fit.Cover and the outer overcoat of interior cover in this compressor comprises with the intermediate sleeve of potassium steel balance weight mfg. moulding die have increased core rod generation erection stress, thereby the also corresponding increase of the extruding force that can offset has improved the bearing capacity of mould.
Above-mentioned compressor with potassium steel balance weight mfg. moulding die in, the magnitude of interference of described interference fit is 0.05mm～0.15mm.The magnitude of interference is in above-mentioned scope, and the effect of interference fit is best, and it is also maximum that core rod is produced erection stress, and the extruding force that can offset is also done greatly, and the bearing capacity of mould is best.
Compared with prior art, this compressor adopts multilayer architecture with potassium steel balance weight mfg. moulding die, can offset most extruding force, and bearing capacity is good, and service life is also longer, and entire die is comparatively light, and production cost is also lower.Simultaneously, this compressor mainly adopts cold extrusion to make the potassium steel balance weight with potassium steel balance weight mfg. moulding die, and the utilization rate of material is higher, and production efficiency is also higher, and the potassium steel balance weight dimensional accuracy of making is high, good rigidly, and intensity is high, and is in light weight.
