Description
(1) technical field
The utility model relates to a kind of axle tube extrusion die, belongs to the extrusion die technical field, specifically belongs to a kind of hot-extrusion mold.
(2) background technology
Axle tube is commonly called as spindle nose, is the major part of bearing load on the truck back axle.Early stage axle tube adopts casting usually, carries out following process then, and is not enough because of the blank dense structure of casting, and may also have various casting flaws, and bad mechanical property has been a kind of technology of almost being eliminated fully.
Also have a kind of forging molding, the axle tube size is elongated, and is hollow structure, and difficult forming is more in the forging process, and is difficult to guarantee machining accuracy.
The Forging Technology that adopts is main two kinds at present, and a kind of is to adopt seamless steel pipe upsetting squeeze on horizontal forging and upsetting machine, because material price is higher, causes production cost to improve; Another kind is to adopt the round bar upsetting squeeze, because in this kind processing method, mould structure forms according to the backward extrusion manufactured of formed product, make that the length of extruding drift must be greater than the forging height, thereby cause the slenderness ratio of extruding drift further to increase, the extruding drift very easily produces distortion, damages in the process of reproduction, and service life is low, needs often to change the extruding drift.In other operations of later stage, also need to set up separately operation to remove the gross weight that backward extrusion stays, or set up independent excision termination operation to remove gross weight, not only work flow is long, and stock utilization is low, and the technological process complexity, has a strong impact on production efficiency.
Mainly by improving the structure of forging die, carry out die forging at present, need be heated usually about 1200 ℃ specific to this elongate articles of axle tube, on large pressing machine, extrusion molding, or be forward extrusion, or be backward extrusion.Concerning the forging that we study today, be the backward extrusion technology that adopts.This technology can make forging dense structure, the fatigue resistance height.But because of the forging blank often need to be heated to very high temperature and and to bear moderate finite deformation stress, so Temperature Influence and power are the problems that design die forging structure must be considered to the effect of mould.
In the punching operation of axle tube, extrusion process mould and blank temperature inside all can change, the result shows, blank is subjected to the effect of the huge power of mould in this process, a large amount of heat energy passes on the mould, plastic deformation or fracture will take place in mould under the effect of power and heat energy, can't guarantee normally to carry out.
When hot extrusion, the working environment very severe of mould except will bearing bigger load, also will be subjected to the influence of alternating temperature-changing.Mould can heat up rapidly because of the Workpiece shaping temperature is high, and cool off fully mould this moment is the necessary condition that mould is kept normal service life.
Mainly be by die is lowered the temperature at present, its method is water-cooling channel to be set mould is cooled off in circle stress.But cooling does not also have good method to punch at present, especially in axle tube die forging punching, if not cooling, plug temperature generally can reach 1000 ℃, its hardness can obviously descend, and influenced by alternating temperature-changing, and its internal residual stress strengthens, it is big that fragility becomes, and causes the punch fracture easily and lost efficacy.Even and if not fracture of punch, its work zone also tends to lose efficacy because of jumping-up.
(3) summary of the invention
The utility model ruptures easily in order to overcome punch, the defective that service life is short, and providing a kind of can cool off punch, the axle tube extrusion die that the life-span is long.
The utility model axle tube extrusion die is by the following technical solutions:
The utility model axle tube extrusion die, mainly form by punch and die, wherein punch comprise convex mould base, inlay within it dash the body seat, be anchored on this on the body seat dash body and with this pierce punch that is fastenedly connected towards body, describedly be connected by the swivel nut that connects that has double thread with pierce punch towards body, wherein be provided with through hole in body, pierce punch then is correspondingly provided with the blind hole up to the work zone; Be provided with intake tunnel and exhalant canal in the described punch holder; Towards body, pierce punch with connect in the passage that swivel nut constitutes and be provided with the water pipe that is connected with above-mentioned intake tunnel, this water pipe outer passage then is connected with above-mentioned exhalant canal above-mentioned.
Above-mentioned axle tube extrusion die, the described swivel nut that connects is that external screw thread connects swivel nut, its polished rod segment length less than join with it and described through hole and the unthreaded hole segment length sum of blind hole.
Above-mentioned axle tube extrusion die describedly is provided with 2 or 4 fabrication holes towards body.
Above-mentioned axle tube extrusion die, described die comprises external carbuncle circle and internal stress circle, be provided with cooling-water duct between two circle stresses, wherein external carbuncle circle upper end has the inlet opening that is communicated with this cooling-water duct, and the respective side lower end has the apopore that is connected with this cooling-water duct.
The utility model axle tube extrusion die, its punch has cavity towards body with this towards the pierce punch inside that body is fastenedly connected, and in this cavity cooling water pipe is set, and intakes from cooling water pipe, from cooling water pipe and this cavity clearance water outlet, reached the drift cooling purpose.Experiment showed, that in this case the drift temperature is lower than 200 degree Celsius, though also can be subjected to the influence of alternating temperature-changing, alternation has a narrow range of temperature, and limiting temperature is not high, and is little to the drift actual influence.And the drift temperature is low, and its intensity reduces few, can reach required intensity with materials with smaller.Employing connects swivel nut and connects towards body and drift, is convenient to change the efficient height.And adopt external screw thread to connect swivel nut, its polished rod segment length less than join with it and described through hole and the unthreaded hole segment length sum of blind hole, the body lower surface that dashes just directly contacts cooperation with pierce punch upper surface face, connect the swivel nut screw thread and arrive fastening effect from now on, can not be subjected to excessive shock loading, the screw thread load impacting inefficacy probability that is hit reduces greatly.On body, be provided for loading and unloading towards body, perhaps fastening again or dismounting during pierce punch clamping be convenient to assembling towards the fabrication hole of body.For die, adopt the scheme that cooling-water duct is set in circle stress can be, and die socket can be too not warm, prevents workman's maloperation, scalded skin to the die efficiently radiates heat.
