Abstract
The utility model relates to a gear carburizing and quenching installing and hanging device. The device comprises a bottom plate, uprights and a davit, wherein the davit is arranged in the middle of the bottom plate, a suspension ring is arranged at the top of the davit, the uprights are uniformly arranged at the upper part of the bottom plate at intervals, and gear holes to be quenched are sheathed on the uprights. Due to the adoption of the device for installing and hanging, the gears can be placed in order and distributed reasonably, the positions in a carburizing furnace in which the gears are placed have the same carburization capacity, and thermal stress and transformation stress in quenching are distributed uniformly, so that the carburization depth of each gear in each furnace is the same, the hardness of the gear is even after quenching, the gear deforms slightly, furnace load quantity for each furnace is guaranteed, the cost is saved, and the economic benefit is improved.
Description
Technical field
The utility model relates to a kind of gear carburizing quenching dress hang device.
Background technology
At present, the carburizing and quenching of gear, what mostly adopt is that gear is put into the charging frame, become the unordered stacking form of putting, gear laminates in cementing furnace mutually, when carrying out carburizing, carburizing atmosphere can not cover each position of gear, cause the carburizing atmosphere at each position of gear different, the depth of penetration of its carburizing and quenching is different, the phenomenon that infiltration layer even occurs not having that has.In addition, this unordered disposing way, the inequality of being heated during gear carburizing quenching, thus cause gear each several part thermal stress distribution inhomogeneous, the gear carburizing quenching distortion is larger, and product percent of pass is low, and production cost is higher.
The utility model content
The purpose of this utility model is to provide a kind of gear carburizing quenching dress hang device.
The technical solution of the utility model is: a kind of gear carburizing quenching dress hang device, it comprises base plate, column, davit, is provided with davit at the middle part of base plate, and the davit top is provided with suspension ring, base plate top evenly is interval with column, and gear hole to be quenched is enclosed within on column.
Carburizing atmosphere can be fully mobile in stove in order to allow, and evenly is provided with the ventilating pit I on described base plate.
Described base plate is circular, and described base plate is provided with evenly spaced hole, and the bottom of column is provided with boss, and the Kong Zhonghou that base plate is inserted in the bottom of column welds together.
In order to ensure the handling for the treatment of Quenched Gear and batch, described carburizing and quenching dress mounts to be set to and stacks more than two-layer or two-layer, described carburizing and quenching dress hang device also comprises dividing plate, riser, described riser is three or more, evenly be fixed on the upper surface of base plate, the height of described column is lower than the height of dividing plate, and the height of described davit is lower than the height of dividing plate, upper surface at riser is provided with dividing plate, in order to stack reposefully this device of multilayer.
Carburizing atmosphere can be fully mobile in stove in order to allow, and evenly is provided with the ventilating pit II on described riser.
In order to ensure firmly, described riser and base plate are for being welded to connect, and the inboard of riser also welds together with davit.
Described riser quantity is three.
Effect of the present utility model: for the carburizing and quenching of gear, adopt this hanger dress to hang, make putting in order of gear, distribute rationally, each gear carburizing atmosphere of present position in cementing furnace is the same, thermal stresses and structural stress during quenching are evenly distributed, thereby make the carburized depth of each gear of each stove the same, and the hardness after quenching is even, the distortion of gear is little, and the batch of each heat is guaranteed, and saves cost, increases economic efficiency.
Description of drawings

Embodiment
Below in conjunction with accompanying drawing, the utility model is further described:
With reference to accompanying drawing, be the two-layer a kind of gear carburizing quenching dress hang device that stacks, it comprises base plate 1, column 2, davit 3, dividing plate 4, riser 5.Base plate 1 is circular configuration, on the different circumference of base plate 1, average mark is furnished with the ventilating pit I, these ventilating pit I are that carburizing atmosphere during for gear wheel carburization is easily by in the ventilating pit I, increase the mobility of carburizing atmosphere, make the carburizing atmosphere in stove consistent, the depth of penetration of gear is even, simultaneously the quenchant when gear is quenched after carburizing passes through in these ventilating pit I again, increase the mobility of quenchant, the gear quenching speed of cooling is consistent, thereby the hardness after gear quenching is even, is out of shape little; Described column 2 is cylindrical structural, and an end of cylinder is processed into step, and step inserts in the hole that is complementary on base plate, then welds with base plate 1.Column 2 is to be on the different circumference that is distributed in regularly base plate 1, and the carburized gears center is with through hole, and the through hole of gear is inserted in column 2, but each column 2 placement of multiple layers gear.The height of column 2 should be lower than the height of dividing plate 4, so that placement of multiple layers dress hang device; Davit 3 one ends are with suspension ring, and suspension ring are advance stove and come out of the stove and link up with the position when quenching as the dress hang device, and the other end is processed into step, and step inserts in the hole of base plate 1, then is welded.The height of davit 3 should be lower than the height of dividing plate 4, so that each heat can multilayer be put this dress hang device; Described dividing plate 4 is rectangular structure, and the one side of rectangular parallelepiped by being welded, is welded with a dividing plate 4 with riser 5 on each riser 5, and dividing plate 4 can play steady effect when stacking this dress hang device; Described riser 5 is ladder structure, and the base of riser 5 and base plate 1 are welded, a side of riser 5 and davit 3 welding.Being evenly distributed a plurality of ventilating pit II on riser 5, is that carburizing atmosphere can be fully mobile in stove in order to allow, and to strengthen its homogeneity, guarantees the furnace atmosphere uniformity, and each dress hang device has three risers 5, and riser 5 is divided into Three regions with base plate 1.
This dress mounts and is set to integrated structure, can carry out multilayer according to the size of cementing furnace and place.
