Abstract
The utility model relates to metal heat processing accessories, particularly to a special hanger for carburizing and quenching, which solves the problem that the conventional hanger is poor in aligning and has slow lifting speed and high manufacturing and maintaining cost. The special hanger is characterized by consisting of a lifting lug made of an inverse U-shaped rod, a rib plate, a base plate, a horn-shaped guiding notch and a step surface connected with a hanging rod of a working material disk, wherein the lifting lug is welded to the base plate and fixed through the rib plate; a through hole is formed at the center of the base plate, the base plate is provided with the step surface connected with the hanging rod of the working material disk; and the horn-shaped guiding notch is formed in the side surface of the base plate. The special hanger is used for lifting the carburizing and quenching devices, and has the advantages of simple manufacturing technology, convenience for operation, long service life and low manufacturing cost.
Description
Technical field
The utility model relates to the metal heat treatmet accessory, particularly the special hanger of workpiece carbonization quenching.
Background technology
Wheel gearing in whole mechanical sector application and extensively, carburizing and quenching is as the heat treatment step of high firmness gear, axle, its quality good and bad directly influences performance and the work-ing life of whole transmission device etc.
When workpiece carries out carburizing and quenching at pit carburizing furnace; Need workpiece be hung out from pit carburizing furnace, move to special-purpose oil-quenching tank and quench, can this process suspender in the shortest time; Tool disk in the stove is blocked, lifted by crane, the quenching quality of workpiece is had very big influence.Slowly will cause that workpiece surface temperature reduces if lifting speed is crossed, cause workpiece surface hardness low, even make the failure of quenching.
At present, the carburizing and quenching suspender that uses in the production according to the size of lifting tool disk, is divided into two kinds of two pawl suspension hooks and clamp speciallies.Two pawl suspension hooks are made up of wire-rope sling, union lever and vulsellum hook.Though simple in structure, cost is low, and is easy and simple to handle, lifting workpiece weight is little, uses limitation bigger, in the lifting process, is difficult for accurately location, once aligns lifting when being difficult to guarantee to quench.Clamp specially is made up of driving lifting mouth, rolling fin, clamp arm, holding bolt, the drive device of clamp arm, retaining plate, lifting chute.Though lift by crane more steadily, the lifting program is complicated, because clamp is not in place can't to be lifted by crane, causes lifting by crane overlong time easily, and workpiece surface temperature descends, and causing the failure of quenching.Under the overall situation of product diversification development, the charging tray suspension rod size of different cementing furnaces is also not of uniform size, needs the frequent change clamp during lifting.Because workpiece is wide in variety, need the clamp specially of outfit many, increased production cost.
Summary of the invention
The purpose of the utility model is intended to overcome the shortcoming of prior art, and a kind of carburizing and quenching special hanger is provided, and solves that traditional suspender is bad to align, and lifting speed is slow, makes the high problem of maintenance cost.
The task of the utility model is to adopt following measure to realize:
A kind of carburizing and quenching special hanger; It is characterized in that: the step surface that the hoisting ring that said special hanger is made up of the inverted U bar, gusset, chassis, tubaeform guiding slot port are connected with suspension rod with the workpiece charging tray is formed; Said hoisting ring and chassis welding, and with the gusset reinforcing, the centre on said chassis is a through hole; And being provided with the step surface that is connected with the suspension rod of workpiece charging tray, said chassis sides has tubaeform guiding slot port.
The utility model is compared with prior art: the step surface that is connected with the suspension rod of workpiece charging tray is set up in (1) on the suspender chassis; And the step surface place leaves big chamfering; The inefficacy that can reduce the collision deformation in the lifting process and cause owing to the sharp corner stress concentration, the security that has improved the lifting process; (2) have tubaeform guiding slot port in the suspender chassis sides, make special hanger and the workpiece charging tray suspension rod time that aligns shorten, improved the quenching quality of production efficiency and workpiece.It is simple to the utlity model has ME, easy and simple to handle, long service life, and advantage of low manufacturing cost can be applied in the lifting of various carburizing and quenchings.
Description of drawings
Fig. 1 is the structural representation of the utility model;
Fig. 2 is the working state schematic representation of the utility model lifting workpiece charging tray.
The utility model is elaborated through the practical implementation process below in conjunction with accompanying drawing.
Embodiment
As shown in Figure 1; A kind of carburizing and quenching special hanger; Hoisting ring 1, gusset 2, chassis 3, tubaeform guiding slot port 4 by the inverted U bar constitutes are also reinforced with gusset 2; The centre on said chassis 3 is a through hole, and is provided with the step surface 5 that is connected with suspension rod 6 tops of workpiece charging tray 7, and 3 sides, said chassis have tubaeform guiding slot port 4.
The working process of the utility model:
As shown in Figure 2, at first travelling crane hook 9 passes hoisting ring 1, hooks special hanger; Move special hanger then to the charging tray that workpiece 8 is housed 7 places, special hanger continues to move, and under the guiding of tubaeform guiding slot port 4, makes the centre on the suspension rod 6 entering suspender chassis 3 of workpiece charging tray 7; The travelling crane hook 9 that hoists makes the step surface 5 on suspender chassis contact with the head bottom surface of the suspension rod 6 of workpiece charging tray 7, thus reach fast align, lifting operation.
The utility model is provided with tubaeform guiding slot port 4 and step surface 5 on suspender chassis 3; Tubaeform guiding slot port 4 can shorten aligning the time of suspender and charging tray suspension rod; Step surface 5 makes suspender chassis 3 with after workpiece charging tray suspension rod 6 contacts; Be not easy to skid off, improved the security of lifting operation.
Claims (1)
1. carburizing and quenching special hanger; It is characterized in that: the hoisting ring that said special hanger is made up of the inverted U bar (1), gusset (2), chassis (3), tubaeform guiding slot port (4) and the step surface (5) that is connected with the suspension rod (6) of workpiece charging tray are formed; Said hoisting ring (1) welds with chassis (3), and reinforces with gusset (2); The centre on said chassis (3) is a through hole, and is provided with the step surface (5) that is connected with the suspension rod (6) of workpiece charging tray, and side, said chassis (3) has tubaeform guiding slot port (4).
