Abstract
The utility model belongs to a technology device for heat treatment, which particularly relates to a technology device of automobile crankshaft normalizing treatment. The utility model is composed of a hanging tool and a cooling device, wherein, a pedestal of the hanging tool is evenly distributed with four positioning seats, each positioning seat is provided with a concave surface corresponding to the big end of a crankshaft, an upper supporting plate is evenly distributed with four circular arcs corresponding to the positioning seats, the circle center of each circular arc and the circle center of each positioning seat are on a straight line which is perpendicular to a secondary pedestal, and the radius of each circular arc is equal to the radius of the main shaft diameter of the crankshaft; the cooling device is composed of a motor, a turbine speed reducer, a driving gear, a driven gear, a rotating platform matched with the pedestal of the hanging tool, and a blower provided with a spraying device. The utility model has the advantage that the crankshaft can be vertically placed and rapidly cooled by the utility model.
Description
(1) technical field
The utility model belongs to the process of thermal treatment device, particularly a kind of treatment process device of automobile crane normalizing.
(2) background technology
State's inside crankshaft thermal treatment generally all is to carry out in pit furnace, and bent axle is placed in stove in vertical state.But because the bent axle quality is big, length is long, when being placed on the process unit, be difficult in vertical state, and unstable, the turnover stove is also inconvenient.On the other hand, when bent axle is come out of the stove cooling, generally adopt the high wind cooling, but because the bent axle diameter of axle is big, cooling performance is unsatisfactory.
(3) summary of the invention
The purpose of this utility model is to provide a kind of can make the vertical suspender of placing of bent axle, and can make the rapid refrigerative refrigerating unit of bent axle.
The purpose of this utility model is achieved in that
The thermal treatment process device of automobile crane normalizing of the present utility model, form by suspender and refrigerating unit, suspender is by base, form with the upper backup pad parallel with base between the base with the vertical montant of base, the vertical cross bar of montant, cross bar, base is evenly equipped with four positioning seats, have on the positioning seat and the corresponding concave surface of crankshaft big end, be evenly equipped with four and the corresponding circular arc of positioning seat on the upper backup pad, the center of circle of circular arc and the center of circle of positioning seat are on a straight line perpendicular to base, and the radius of circular arc equals the radius in crank spindle footpath.
The thermal treatment process device of automobile crane normalizing of the present utility model, its refrigerating unit are the rotation platforms that matches by motor, reducer of turbodrill, driving toothed gear, passive gear, with the suspender base, and the blower fan that has a spraying plant is formed.
This process unit is that the thermal treatment characteristics according to the bent axle normalizing manufacture and design.The heat treated technical requirements of bent axle normalizing have two very important, the one, the axial runout of bent axle is little, the 2nd, the hardness after the normalizing is suitable.Because crankshaft length is long, the bent axle diameter is big, when heating and cooling, has only vertical placement, just can make axial runout little, because the bent axle cross section exists greatly, air cooling is too slow, only takes to force cooling provision, just can make hardness reach technical requirements simultaneously.
Therefore, the utlity model has bent axle is vertically placed, and make bent axle refrigerative advantage rapidly.

Among the figure, 11, cross bar, 12, chain link, 13, montant, 14, upper backup pad, 15, stiffening web, 16, positioning seat, 17, base, 18, circular arc, 21, motor cabinet, 22, motor, 23, reducer of turbodrill, 24, driving toothed gear, 25, blower fan, 26, rotation platform, 27, fan supporter, 28, passive gear
(5) embodiment
Fig. 1, Fig. 2 have provided hanger structure figure and cooling system synoptic diagram.
As shown in Figure 1, suspender is to be 600 millimeters base (17) by diameter, with the vertical height of base be 1800 millimeters montant (13), the vertical diameter of montant is 50 millimeters a cross bar (11), cross bar is formed with the upper backup pad (14) at a distance of 875 millimeters parallel with base between the base, base (17) is evenly equipped with four positioning seats (16), be evenly equipped with four and the corresponding circular arc of positioning seat (16) (18) on the upper backup pad (14), the center of circle of circular arc and the center of circle of positioning seat are on a straight line perpendicular to base, and the radius of circular arc equals the radius in crank spindle footpath.
When normalizing, the big end of bent axle is downward, and the big end of bent axle is placed on positioning seat (16) lining, and bent axle is located rapidly, and prevents that the crankshaft big end face from sliding.Upper backup pad (14) circular arc (18) contacts just with the main shaft diameter surface, and bent axle is played a supportive role.Use chain link (12) to entangle at last and contact just, bent axle is played a supportive role with the main shaft diameter surface.Use chain link (12) to entangle the bent axle small end at last, angle cross bar (11) turnover normalizing furnace with crane.
As shown in Figure 2, refrigerating unit is the rotation platform (26) that matches by motor (22), reducer of turbodrill (23), driving toothed gear (24), passive gear (28), with suspender base (17), and the blower fan that has a spraying plant is formed.
When cooling, bent axle after coming out of the stove is placed on together with suspender on the rotation platform (26) of cooling system, rotates with a certain rotating speed by reducer of turbodrill (23), driving toothed gear (24), passive gear (28) drive platform by the motor (22) that is installed on the motor cabinet (21).In a side of rotation platform, a cooling blower (25) that has spraying plant is installed, blower fan is installed in fan supporter (27), changes the speed of cooling of bent axle by the size of regulating spray amount.
