Description
Technical field
The utility model relates to hardened tool field, bull gear location, particularly relates to a kind of gear ring and automatically overlaps die quenching locating device.
Background technology
Present stage, have following four kinds of heat treating methods to middle hard gear-face large diameter thin wall ring gear both at home and abroad: overall modified+teeth portion nitrogenize, overall modified+teeth portion induction quenching, overall carburizing and quenching and entirety are modified.From indexs such as surface hardness, centre hardness and the Available Hardened Depths, the anti-contact fatigue strength of the flank of tooth that overall carburizing quenching process obtains and the counter-bending fatigue strength of teeth portion is the highest, obdurability is best, longest-lived, but its thermal treatment process is also the most difficult.The distortion produced in carburizing and quenching process is the major cause hindering carburizing and quenching ring gear large-scale application on high-precision heavy-load gear box.
Carburizing and quenching has following several method:
1) direct quenching after carburizing, then use the method for manual synchronizing.This method does not limit shape measure when quenching, gear ring is in free deformation, and the gear ring roundness deformation of diameter 1700mm generally reaches 4-7mm, and domestic maximum distortion when having producer to test has 11mm, common normal is followed with other indexs are irregular especially, substantially can not produce qualified product.
2) Special quenching die quenching is adopted after carburizing.Hess company of Germany produced the large gear ring Quenching press of 1.5m, and domestic existing subscriber, is out of shape at 0.4-0.7mm.For the ring gear of 1500-2000mm, comprising our department of Hess Germany does not have knowhow yet, can only guarantee the roundness deformation within 1.0mm, and separate unit press (maximum diameter 2000mm) offers 1,800,000 Euros.The circle class Special quenching press that domestic Ningxia mechanical investigations is produced can only ensure the roundness deformation of 1.0 ‰ D, and namely the gear ring roundness deformation of diameter 1500mm ensures within 1.5mm, does not do more than the product of 1500mm.
3) adopting particular manufacturing craft, being inserted in ring gear endoporus when quenching, force to correct to the quenching strain of ring gear.This method obtains large-scale application in German RENK company, and 1500-2000mm ring gear roundness deformation controls within the scope of 0.5-0.7mm.But this method all adopts manual operation abroad when actually operating, because when mould is inserted in gear ring, mould and gear ring gap very little, with mechanism be difficult to ensure successfully.
Summary of the invention
Automatically be inserted in the problem of gear ring to solve mould, the utility model provides a kind of gear ring automatically to overlap die quenching locating device, and its automatic cover die precision is high, can realize product from the whole automatization of cover die quenching of coming out of the stove, and success ratio is up to 100%.
For this reason, the technical solution of the utility model is as follows:
A kind of gear ring overlaps die quenching locating device automatically, for realizing the concentrically located of gear ring and mould, comprise main body rack, mould concentrically located cylinder, mold cramping motor, mould pawl and die lifting device, described mould concentrically located cylinder has 4, be separately fixed on the same plane of described main body rack, and stand on gear ring periphery by 90 ° of spacing ring windings; The top of described 4 mould concentrically located cylinders is equipped with support plate, and described support plate is divided into two sections, and internal diameter and the gear ring external diameter of the support plate hypomere relatively set up match, and epimere internal diameter and mould external diameter match; Described die lifting device is fixed on described main body rack, and its position and mould concentrically located cylinder perpendicular; Die lifting device is provided with mold cramping motor, and mold cramping motor is connected with swingable mould pawl.
Described die lifting device comprises the die lifting cylinder be fixed on described main body rack, wireline, tackleblock and drives wireline to control the mold cramping electric machine support moved up and down through tackleblock by described die lifting cylinder.Described mold cramping motor is fixedly installed on described mold cramping electric machine support, is synchronized with the movement with electric machine support.
The quenching bench also comprising quenching bench lifting motor, elevating lever and drive it to move up and down by described quenching bench lifting motor through elevating lever; Described quenching bench lifting motor is fixed on described main body rack.
The epimere of described support plate is arc.
The hypomere of described support plate is arc.
This gear ring overlaps die quenching locating device automatically, and its automatic cover die precision is high, and 1500-2000mm ring gear roundness deformation controls within the scope of 0.5-0.7mm, can realize product from the whole automatization of cover die quenching of coming out of the stove, and success ratio is up to 100%.
Accompanying drawing explanation
Fig. 1 is the structure iron that the utility model gear ring overlaps die quenching locating device automatically.
Embodiment
Below in conjunction with accompanying drawing, the structure that the utility model gear ring overlaps die quenching locating device is automatically described in detail.
As shown in Figure 1, gear ring 1 is placed on quenching bench 10, is fixed on 90 °, 4 mould concentrically located cylinder 3 intervals on main body rack 12 around the periphery being built in gear ring 1 position, and in the same plane; The top of these 4 mould concentrically located cylinders 3 is equipped with support plate 11, and support plate 11 is divided into two sections, and the internal diameter of support plate hypomere 11b relatively set up and the external diameter of gear ring 1 match, and the external diameter of epimere 11a internal diameter and mould 2 matches; Die lifting device is fixed on main body rack 12, and its position and mould concentrically located cylinder 3 perpendicular; Die lifting device is provided with mold cramping motor 8, and mold cramping motor 8 is connected with swingable mould pawl 9.After mould pawl 9 installs mould 2, be positioned at directly over gear ring 1 position by die lifting device adjustment mould 2.
In an embodiment of the present utility model, the epimere 11a of support plate is arc; The hypomere 11b of support plate is also arc.
