Description
Technical field
The utility model is related to technical field of metal heat treatment, and more particularly to a kind of high-temperature carburizing large gear erects quenching
Frock.
Background technology
The deformation of large gear carburizing and quenching is directly connected to the quality index such as the strength of gear teeth, precision.For carburizing and quenching
Gear, particularly large gear, its deflection is very big, and is difficult to control to.Larger deformation can not only make the mill that roll flute is processed
Amount increases, and cost is improved, and influence gear manufacture precision, reduces bearing capacity, and terminal life can also be greatly reduced.Large-scale tooth
The residual stress that the deformation of wheel carburizing and quenching is produced mainly due to workpiece in machining, produces in heat treatment process
Thermal stress and the collective effect such as structural stress and workpiece deformation induced by gravity and produce.
The factor of influence gear carburizing quenching deformation is a lot, including the geometry of gear, raw material and metallurgical quality, forging
Make and the aspect such as mach residual stress, charging method and Technology for Heating Processing and equipment.Reduce gear carburizing quenching deformation, energy
The bearing capacity and service life of gear are enough improved, to shortening the manufacturing cycle, production cost is reduced also all significant.
In order to solve the above problems, the present inventor have devised a kind of large-scale tooth of high-temperature carburizing in terms of Equipment for Heating Processing
Wheel erects quenching frock.
Utility model content
The technical problems to be solved in the utility model is to provide a kind of high-temperature carburizing of deformation problems when can solve the problem that quenching
Large gear erects quenching frock.
In order to solve the above technical problems, the technical solution of the utility model is：A kind of high-temperature carburizing large gear is erect and is quenched
Firer fills, and its innovative point is：Including suspender, crossbeam, base, on base, the crossbeam includes two to the beam erection
Parallel transverse slat and for connecting two connecting plates of transverse slat, the base is in " Ш " shape, and the base includes being arranged on ground
On base plate and the supporting plate perpendicular with base plate, the supporting plate has three and is parallel to each other, be respectively perpendicular and be arranged on bottom
The left end of plate, middle and right-hand member, offer the groove for placing crossbeam, the base in the middle of the upper surface of the supporting plate
Left and right sides level be welded with lifting plate.
Further, some reinforcements are welded with the supporting plate.
Further, diameter of the width of the crossbeam less than large gear.
Further, the suspender is hoisting chain.
The utility model has the advantage of：A kind of high-temperature carburizing large gear erects quenching frock, simple structure, quality
Gently, loading gear is reliable, with strong points, overcoming when keep flat quenching after large gear high-temperature carburizing that circularity and plane precision can not
The problem of control, reduces the loss to the energy and hardening media.
Brief description of the drawings
The utility model is described in further detail with reference to the accompanying drawings and detailed description.
Fig. 1 is the structural representation that a kind of high-temperature carburizing large gear of the utility model erects quenching frock.
Specific embodiment
The following examples can make professional and technical personnel that the utility model is more fully understood, but therefore will not
The utility model is limited among described scope of embodiments.
As shown in figure 1, a kind of high-temperature carburizing large gear erects quenching frock, including suspender 1, crossbeam 2, base 3, suspender
1 is hoisting chain, the diameter of the width less than large gear 4 of crossbeam 2.Crossbeam 2 sets up on the base 3, and crossbeam 2 includes that two are put down
Capable transverse slat 21 and for connecting two connecting plates of transverse slat 21 22, base 3 is in " Ш " shape, and base 3 includes setting on the ground
Base plate 31 and the supporting plate 32 perpendicular with base plate 31, supporting plate 32 has three and is parallel to each other, be respectively perpendicular and be arranged on
The left end of base plate 31, middle and right-hand member, offer the groove 35 for placing crossbeam 2 in the middle of the upper surface of supporting plate 32, prop up
Some reinforcements 33 are welded with fagging 32, the left and right sides level of base 3 is welded with lifting plate 34.
When using, first large gear 4 is erect on crossbeam 2, then crossbeam 2 is erected at the supporting plate 32 of base 3
On, high-temperature carburizing large gear is erect into quenching frock and the hoisting chain of large gear 4 is lifted to heat-treatment furnace and added together
Heat, during cooling, is hung to hardening media and is cooled using hoisting chain by crossbeam 2 and large gear 4.
General principle of the present utility model and principal character and advantage of the present utility model has been shown and described above.This
The technical staff of industry is retouched in above-described embodiment and specification it should be appreciated that the utility model is not restricted to the described embodiments
That states simply illustrates principle of the present utility model, on the premise of the utility model spirit and scope are not departed from, the utility model
Various changes and modifications are also had, these changes and improvements are both fallen within the range of claimed the utility model.This practicality is new
The claimed scope of type is by appending claims and its equivalent thereof.
