Abstract
The utility model discloses a hanging-type rotating quenching device of an axle. The device mainly comprises a rotating hanging device of the axle, a chain wheel and transmission chain systems, an axle movement and support system, a water collecting pipe and nozzle system and movable water blocking curtain plates, wherein the hanging device is arranged on the axle movement and support system, a chain wheel is arranged on the upper end of the hanging device, the movable transmission chain systems are arranged on two sides of the chain wheel; the movable water blocking curtain plates and the water collecting pipe and nozzle system are arranged on two sides of a quasi quenching axle inside a quenching cooling chamber, and water collecting pipe and nozzle system is connected with a cooling medium circulation system. The device disclosed by the utility model has the advantages that (1) since a mode that the axle is vertically hung and rotated is adopted, uniformly quenching and cooling of the whole axle can be ensured, thus a bend generated by uneven cooling can be avoided; (2) since a mode that the cooling mediums are in motion under double pressures and permanent stream is adopted, the stability and the reliability of the system are improved; and (3) since the movable water blocking curtain plates are designed, the quenching cooling speed can be ensured to be stable and controlled.
Description
Technical field
The utility model belongs to metal heating processing technology equipment, particularly the quench treatment of the shaft-like workpiece such as axletree.
Background technology
The quenching of the shaft-like workpieces such as axletree (hereinafter to be referred as axletree) is that it is carried out modified heat treated key link.At present axletree commonly used quenches and is equipped for horizontal immersion, and the horizontal immersion of axletree of namely adopting hanging basket or carriage or other similar mechanical systems to take out from process furnace fills to be carried out coolingly in the groove of quenching medium, realize quench treatment.
The axletree of prior art quenches and is equipped for horizontal immersion, and its shortcoming is: 1. in the process that immerses heat-eliminating medium, the bottom of axletree is cooling prior to top, therefore, easily produces crooked and causes axletree and scrap.2. in whole process of cooling, axletree is normally motionless, when the stirring of heat-eliminating medium is abundant not, just can not timely and effectively abolish the surperficial vaporization layer of axletree, add the difference of position, easily cause the speed of cooling difference of different sites excessive, thereby affect the quenching quality of whole axletree.
Summary of the invention
The purpose of this utility model is to overcome the shortcoming of prior art, provides a kind of the shaft-like workpieces such as train shaft are vertically hung, and make the cooling quenching device of bearing total length synchronous rotary, solves existing level immersion equipment and easily causes the quality problems such as bent axle.
The utility model is achieved through the following technical solutions:
A kind of axletree suspending rotary quenching device, comprise axletree rotating lifting hang device, sprocket wheel and transmission chain system, axletree moves and supporting system, header and nozzle system, and mobile dash curtain plate; Described erecting by overhang be arranged on axletree move with supporting system on, sprocket wheel is installed in the upper end, sprocket wheel both sides configure movably the transmission chain system; Mobile dash curtain plate and header and nozzle system are arranged on the indoor plan of quench cooled quench axletree both sides, and header is connected with cooling medium circulation system with nozzle system.
The utility model has the advantages that:
1. owing to adopting the mode of axletree vertically being hung and made its rotation, can guarantee the even of whole axletree quench cooled, thereby avoid the bending because of the inhomogeneous cooling generation.
2. owing to adopting the two pressure permanent current operation scheme of heat-eliminating medium, improved system stability and reliability.
3. owing to having designed mobile dash curtain plate, can guarantee the stable and controlled of quench cooling rate.
Description of drawings
Fig. 1 is structural representation of the present utility model.
Fig. 2 is that axletree of the present utility model moves and the local enlarged diagram of supporting system.
Embodiment
The utility model is further described by embodiment below in conjunction with accompanying drawing.
As shown in Figure 1, a kind of axletree suspending rotary quenching device of the present utility model, comprise the rotating lifting hang device 1, sprocket wheel of axletree 10 and transmission chain system 2, axletree move 3 with supporting system 4, header and nozzle system 5, mobile dash curtain plate 6; Erecting by overhang be arranged on axletree move with supporting system on, sprocket wheel is installed in the upper end, sprocket wheel both sides configure movably the transmission chain system; Mobile dash curtain plate and header and nozzle system are arranged on the indoor plan of quench cooled quench axletree both sides, and header is connected with cooling medium circulation system with nozzle system.As shown in Figure 2, wherein:
Rotating lifting hang device: by turning axle 1-1, be contained in the drop in beam 1-2 of turning axle bottom and the two clamping plate 1-3 that are contained in the drop in beam lower end and are used for clamping the spindle nose footpath section of train shaft form; Sprocket wheel and transmission chain system 2 are installed on turning axle top;
The axletree mobile system: the axletree mobile system is travelling car 3-1, and the turning axle 1-1 of described rotating lifting hang device is equipped with bearing 3-2, and by bearing gland 3-3, turning axle is contained in travelling car by the travelling car center on turning axle; Axletree mobile system or for the travelling car of roller.
Supporting system: supporting system 4 is supporting beam 4-1 and the roller-way that is fixed on the roller 4-2 on supporting beam and is formed by some rollers, and travelling car 3-1 is mobile operation on roller-way.Supporting system 4 or for supporting beam 4-1 and supporting beam arrange track orbits with the travelling car of roller
A kind of axletree suspending rotary quenching device of the present utility model can be designed to many quench cooled station, realizes simultaneously the quench treatment of many axletrees.
Implementation step of the present utility model is as follows:
Axletree vertically is hung on the rotating lifting hang device, and transmission mechanism drives suspender and axletree together rotates, and both sides are simultaneously cooling up and down; For guaranteeing to spray simultaneously heat-eliminating medium and to avoid the generation of water hammer along the cooling jet that the axle length direction is arranged, the quenching axletree enters in the quench station process, the operation of cooling medium circulation system low-pressure low flow; For the heat-eliminating medium splash of process mesolow operation avoiding entering quench station at axletree to axletree, the mobile dash curtain plate of design be placed in nozzle just before; After axletree arrives quench station and begins rotation, the heat-eliminating medium system is transformed into the pressure operation of setting, mobile dash curtain plate is to the quenching position simultaneously, and the heat-eliminating medium of nozzle ejection is sprayed onto on axletree by the hole of dash curtain plate, realizes cooling to the quench treatment of axletree.
