Abstract
A kind of hot extrusion instead squeezes drift cooling device, squeezes drift for heat of cooling extruding is anti-.Anti-blind hole of squeezing drift heart portion leads to anti-crowded ram bottom, and plug is equipped with at blind hole oral area internal thread place; The anti-drift that squeezes has drainage hole, through with blind hole respectively; Inlet opening is built with adpting flange, and adpting flange is connected with flexible pipe one end, and the flexible pipe other end leads to anti-crowded ram bottom, and inlet opening oral area is rotary with the joint one with through hole, and joint one press joining method is blue, and joint one is connected with water inlet pipe; Osculum oral area is rotary with the joint two with through hole, and joint two is connected with drainpipe; Water inlet pipe, joint one, adpting flange, flexible pipe composition water inlet cooling device; Blind hole, osculum, joint two, drainpipe composition drainage cooling device.The utility model, by cooling back installation, makes cooling water in drift inner loop, is taken away in time by drift top layer heat, reduce drift skin temperature, high life, alleviate labor strength, improve product endoporus Forming Quality.
Description
Technical field
The utility model relates to machinery manufacturing technology field, and specifically the cooling device of drift is instead squeezed in a kind of hot extrusion for hub axle tube punching.
Background technology
In the manufacturing process of hub axle tube, the important component part that drift is mould is instead squeezed in hot extrusion, anti-crowded drift is longer for time of contact with about 1000 DEG C of metal stocks, anti-drift skin temperature of squeezing sharply rises to 400 ~ 600 DEG C, if cooling not in time will more than 650 DEG C, hardness reduces, and causes that counter to squeeze drift weak.In the anti-extrusion forming process of hub axle tube hot extrusion, because the flowing of metal plastic deformation fierceness and the anti-drift that squeezes form strong friction, the anti-drift that squeezes is caused to bear very large extruding force and hot friction.Anti-also bear tension and occlusion cementation power when squeezing the drift demoulding, instead squeeze after drift only has and depart from completely with workpiece, water spray ring water-spraying control could be used.Through heating and cooling repeatedly, make instead to squeeze drift top layer Swelling and contraction repeatedly, because of internal layer and outer breathing inconsistent, form thermal stress, mechanical stress, even occur structural stress, multiple Stress superposition causes instead squeezing the damages such as drift fracture, cracking, heat fatigue be full of cracks, cause production cost high, labor strength is large, and production efficiency is low, and hub axle tube endoporus quality not easily ensures.
Summary of the invention
For overcoming the deficiencies in the prior art, goal of the invention of the present utility model is to provide a kind of hot extrusion instead to squeeze drift cooling device, by instead squeezing in hot extrusion, the water flowing cooling of drift inside is anti-squeezes drift, to cool anti-crowded drift top layer in time, ensures that anti-drift skin temperature of squeezing does not raise.
To achieve these goals, the heart portion that the utility model instead squeezes drift has blind hole, and blind hole leads to the anti-bottom squeezing drift, and the oral area of blind hole is with internal thread, and plug is equipped with at internal thread place; Anti-guide table of squeezing drift has inlet opening and osculum, and inlet opening and osculum are through with blind hole respectively; Inlet opening is built with adpting flange, and adpting flange is connected with one end of flexible pipe, and the other end of flexible pipe leads to the anti-bottom squeezing drift, and the oral area of inlet opening is rotary with joint one, and joint one is with through hole, and joint one press joining method is blue, and joint one is connected with water inlet pipe; The oral area of osculum is rotary with joint two, and joint two is with through hole, and joint two is connected with drainpipe; Described water inlet pipe, joint one, adpting flange, flexible pipe composition water inlet cooling device; Blind hole, osculum, joint two, drainpipe composition drainage cooling device.
The utility model squeezes drift cooling back installation by anti-, makes cooling water squeeze drift inner loop anti-, takes away instead squeezing drift top layer heat in time, instead squeezes drift skin temperature to reduce, and improves hot extrusion and instead squeezes drift service life.
The utility model compared with prior art, has the following advantages:
1, operating personnel do not need repeatedly to cool anti-crowded drift, automatically cool anti-crowded drift, alleviate the labour intensity of workman by cooling back installation.
2, instead squeeze drift by cooling back installation cooling, anti-drift temperature of squeezing is low, can not reduce anti-crowded punch head surface hardness, can not affect the wearability of punch head surface.
3, anti-crowded drift internal layer and skin temperature are more or less the same, and skin temperature is not high, and heat fatigue can not be caused to damage, and substantially increase anti-service life of squeezing drift.
4, anti-drift skin temperature of squeezing is low, not easy fracture, cracking, distortion and aging, raising is anti-squeeze drift service life while also improve product endoporus Forming Quality.

Fig. 1 is structure diagram of the present utility model.
Detailed description of the invention
As shown in Figure 1, the heart portion that the utility model instead squeezes drift 1 has blind hole 2, and blind hole 2 leads to the anti-bottom squeezing drift 1, and the oral area of blind hole 2 is with internal thread, and plug 6 is equipped with at internal thread place; Anti-guide table of squeezing drift 1 has inlet opening 4 and osculum 5, and inlet opening 4 and osculum 5 are through with blind hole 2 respectively; Inlet opening 4 is built with adpting flange 9, and adpting flange 9 is connected with one end of flexible pipe 3, and the other end of flexible pipe 3 leads to the anti-bottom squeezing drift 1, the oral area of inlet opening 4 is rotary with joint 1, joint 1 with through hole, joint 1 press joining method orchid 9, joint 1 is connected with water inlet pipe; The oral area of osculum 5 is rotary with joint 28, and joint 28 is with through hole, and joint 28 is connected with drainpipe; Described water inlet pipe, joint 1, adpting flange 9, flexible pipe 3 composition water inlet cooling device; Blind hole 2, osculum 5, joint 28, drainpipe composition drainage cooling device.
The utility model is by the anti-drift cooling-cycle device that squeezes of the compositions such as water inlet pipe, inlet opening 4, joint 1, adpting flange 9, flexible pipe 3, blind hole 2, osculum 5, joint 8, drainpipe, make cooling water in anti-inner loop cooling of squeezing drift 1, the top layer heat instead squeezing drift 1 is taken away in time, reduce anti-skin temperature of squeezing drift 1, thus improve the service life that drift 1 is instead squeezed in hot extrusion.
