Description

Bellows under a kind of quenching unit

Technical field

This utility model relates to shape press quenching device, the leeward of a kind of aluminium section bar press quenching device Case.

Background technology

Along with aluminium section bar is used widely the quality to aluminium section bar, mechanical property in the fields such as industry, transportation Requiring more and more higher, existing water hardening, air-blast quenching equipment can only unilaterally carry out online water hardening or air-cooled quench Fire, it is impossible to meet online extruding different aluminum section bar and carry out the requirement of different Cooling Quenching mode.At present, it is common to use water-cooled quench Fire mode be " cross water-cooled " or the mode that sprays is carried out, and there is intensity of cooling not high enough, it is impossible to enough wash high temperature aluminum section bar table open The water smoke that face is formed, thus reduce quenching quality, in addition during spray quenching, its hydraulic pressure is all either manually or automatically to carry out Entirety is heightened or entirety is turned down, it is impossible to enough realizes the hydraulic demand of the aluminium section bar different parts of asymmetric, then causes cold The most uniform, cold deformation is more serious；The air-blast quenching mode commonly used is, sets in the both sides up and down of aluminium section bar conveyer device Putting air cooling equipment, the left and right sides of aluminium section bar can cause inhomogeneous cooling even then, and the situation of cold deformation is more serious.Prior art In, the quenching unit of section bar has the disadvantage in that quenching unit is not provided that sufficiently large rate of cooling scope, it is impossible to according to not Different rate of cooling is selected with alloy and section bar wall thickness；The bad adaptability of quenching unit, due to section bar cross section the most all Being asymmetric, wall thickness is not uniform, therefore when section bar quenches, needs the wall thickness according to section bar to regulate quenching cooling speed Degree；But existing section bar quenching unit, it can not carry out rate of cooling size according to the situation in section bar different parts cross section Regulation, quenching can often occur that the local of heavy wall cools down slow, the fast cooling problem in place of thin-walled, cause section bar deformation and performance Uneven；Quenching unit operability is poor, workman's practical operation difficulty, poor accuracy, and time-consumingly, it is impossible to meet use demand.

Utility model content

The purpose of this utility model is to provide a kind of quenching unit making aluminium section bar can uniformly cool down in quenching process Lower bellows.

For achieving the above object, the technical solution of the utility model is:

Bellows under a kind of quenching unit, including leeward box main body, lower bellows fixture, water retaining cover, YE, wind Door, air port, bottom, bottom spray system, bottom spraying system.All bottoms spray system, the equal position of spraying system water inlet pipe, bottom In the inside of leeward box main body, shower nozzle is arranged with air port dislocation, makes whole quenching system cooling source be evenly distributed.Bottom time air-cooled The air quantity that air feed unit provides will enter leeward box main body again after air door through air supply line and be evenly distributed to each air port.Often The big I of row tuyere air volume is set by touch screen diagram orientation, air port and numerical monitor (percentage ratio), control system after setting The regulation of air quantity is realized by driving YE to rotate air door.For preventing cooling water to be spread across on YE, in leeward Box main body lower periphery has welded water retaining cover.Water retaining cover and leeward box main body full weld, YE is positioned at inside water retaining cover, cold But water can only flow to water tank from the outer of water retaining cover and prevents YE from damaging.All of bottom spray system in bellows, under Portion's spraying system each column all divides multistage (at least 2 sections) each column, the flow of every section can regulate each water supply line by control system Regulation valve regulates, and can realize multistage order keying by control system, to adapt to different-alloy and the quenching of cross section section bar Need, reach different progressive refrigerating modes.Air door respectively enters with air supply line, all bottoms spray system, bottom spraying system The lifting of the convenient lower bellows that are flexible coupling all is used between water pipe and regulation valve.Lower bellows are fixed on entirely through lower bellows fixture On section bar transporter, realized the lifting of lower bellows by section bar conveyor elevator structure, adapt to quenching of different size section bar Fire needs.

The major advantage of lower bellows in quenching unit: the air quantity that bottom air feed unit provides is delivered to each air port uniformly Place, makes aluminium section bar uniformly to cool down.Need to be adjusted by touch screen diagram orientation, air port and numerical monitor (percentage ratio) according to quenching The size of whole each column tuyere air volume, to adapt to the quenching needs of different-alloy and cross section section bar.Air port is adjusted by oscilaltion Position, adapt to different size section bar quenching needs.

Detailed description of the invention

In conjunction with Fig. 1, describe detailed description of the invention of the present utility model in detail, but claim is not limited in any way.

Bellows under a kind of quenching unit, including leeward box main body 1, lower bellows fixture 2, water retaining cover 3, YE 4, Air door 5, air port, bottom 6, bottom spray system 7, bottom spraying system 8.All bottoms spray system 7, bottom spraying system 8 enter Water pipe is respectively positioned on the inside of leeward box main body 1, and shower nozzle is arranged with air port dislocation, made whole quenching system cooling source be evenly distributed. The air quantity that time air-cooled, air feed unit in bottom provides will enter leeward box main body 1 again after air door 5 through air supply line and uniformly divide Cloth is to each air port.The big I of each column tuyere air volume is set by touch screen diagram orientation, air port and numerical monitor (percentage ratio), After setting, control system will drive YE 4 to rotate air door 5 to realize the regulation of air quantity.For preventing cooling water to be spread across electronic On executor 4, weld water retaining cover 3 in leeward box main body 1 lower periphery.Water retaining cover 3 and leeward box main body 1 full weld, electronic hold It is internal that row device 4 is positioned at water retaining cover 3, and cooling water can only flow to water tank and prevent YE 4 from damaging from the outer of water retaining cover 3.Wind In case, all of bottom spray system 7, bottom spraying system 8 each column all divide multistage (at least 2 sections) each column, the flow of every section to lead to The regulation valve crossing the control system each water supply line of regulation regulates, and can realize multistage order keying and list by control system Row, to adapt to the quenching needs of different-alloy and cross section section bar, reach different progressive refrigerating modes.Air door and air supply line, The liter of the convenient lower bellows that are flexible coupling all is used between all bottoms spray system 7, each water inlet pipe of bottom spraying system 8 and regulation valve Fall.Lower bellows are fixed on section bar transporter entirely through lower bellows fixture 2, real by section bar conveyor elevator structure The now lifting of bellows, adapts to the quenching needs of different size section bar.

The Main Function of lower bellows in quenching unit: the air quantity that bottom air feed unit provides is delivered to each air port uniformly Place, makes aluminium section bar uniformly to cool down.Need to be adjusted by touch screen diagram orientation, air port and numerical monitor (percentage ratio) according to quenching The size of whole each column tuyere air volume, to adapt to the quenching needs of different-alloy and cross section section bar.Air port is adjusted by oscilaltion Position, adapt to different size section bar quenching needs.
