Abstract
The utility model provides a combined pressing and quenching mandrel which comprises an upper part and a lower part, wherein a convex part of the upper part, at the lower end of the upper part, is fixedly arranged above the lower part, so that a gap which is an oil drainage channel exists between the upper and lower parts; a plurality of oil inlet channels are arranged inside the lower part, and each oil inlet channel is communicated with the oil drainage channel with corresponding position; the included angle between the outlet direction of the oil drainage channel and the generatrix of the lower part is an acute angle or an obtuse angle. The utility model provides the combined pressing and quenching mandrel provided with an inclined cooling oil channel, so that a cooling liquid can flow down slantly to the benefit of deformation control of a workpiece, thereby improving the precision of the pressed and quenched workpiece by a level. As the mandrel is assembled after split manufacturing, the manufacturing difficulty is greatly lowered.
Description
Technical field
The utility model belongs to heat treatment device field, relates to a kind of Combined press axle of quenching.
Background technology
At present, press that to quench be substantially all to adopt the axle of embossing key path to press and quench as limit shape for the limit shape of synchronous device, rely on the shape and size precision of axle, the contraction of workpiece guarantees when quenching by spray cooling fluid after workpiece austenitizing.But be aimed at the tooth cover of large size thick structure, due to the large reason of thickness of workpiece, the cooling consistence difference of workpiece upper and lower end face also strengthens thereupon, and it is not fine often for the circularity of workpiece, controlling, and the size at the upper and lower two ends of workpiece also exists larger difference simultaneously.Make the final precision of workpiece can not meet processing requirement.
Summary of the invention
Problem to be solved in the utility model is to provide a kind of Combined press axle of quenching, and is especially suitable for limitting shape quenching field.
For solving the problems of the technologies described above, the technical solution adopted in the utility model is: a kind of Combined press axle of quenching, comprise upper and lower, described top is partly fixed on the top of described bottom by being positioned at the evagination of its lower end, make to have gap between described top and described bottom, described gap is oil extraction oil duct;
The inside of described bottom is provided with some oil-feed oil ducts, described in each oil-feed oil duct respectively and the described oil extraction oil duct corresponding with its position communicate;
Angle between the Way out of described oil extraction oil duct and the bus of described bottom is acute angle or obtuse angle.
The utility model can also adopt following technical measures:
Described top and described bottom are by fixing through the screw of described evagination partial interior, and described screw apical side height is less than or equal to the height of described upper top.
Between the Way out of described oil extraction oil duct and the bus of described bottom, being acute angle is 70 °.
Described in each, oil-feed oil duct is all parallel with the central axis of described bottom, and described in each, oil-feed oil duct is uniformly distributed around the central axis of described bottom.
The quantity of described oil-feed oil duct is 12.
Described screw number through described evagination partial interior is 4.
Advantage and the positively effect that the utlity model has are: the utility model provides a kind of Combined press with inclined cooling plate oil duct axle of quenching, cooling fluid can be flowed oblique below, the Deformation control that is conducive to workpiece, makes to press the workpiece accuracy after quenching to improve a grade; Because be to assemble after split production, its manufacture difficulty is reduced greatly.
Accompanying drawing explanation
Fig. 1 is structural representation and the vertical view thereof that tradition is pressed the axle of quenching;
Fig. 2 is structural representation and the vertical view thereof of the utility model embodiment.
In figure:
1, top 2, bottom 3, oil extraction oil duct 4, oil-feed oil duct
5, workpiece 6, screw
Embodiment
As shown in Figure 2, the utility model provides a kind of Combined press axle of quenching, and its top 1 and bottom 2 are fixing by the screw 6 through its top 1 lower end evagination partial interior, and screw 6 apical side heights are less than the height of top 1 end face, and screw 6 quantity are 4.Between top 1 and bottom 2, exist gap to be oil extraction oil duct 3, the inside of bottom 2 is provided with 12 oil-feed oil ducts 4, each oil-feed oil duct 4 respectively and the oil extraction oil duct 3 corresponding with its position communicate, each oil-feed oil duct 4 is all parallel with the central axis of bottom 2, and each oil-feed oil duct 4 around bottom, 2 central axis is uniformly distributed.Between the bus of the Way out of oil extraction oil duct 3 and bottom 2, being acute angle is 70 °.
Press the axle of quenching to compare with tradition shown in Fig. 1, this Combined press axle of quenching is connected and combines with bottom by top for 1 minute for 2 minutes.The direction of spindle oil road outlet and axle outside are the angle of 70 °, and cooling fluid can be flowed oblique below, and this kind of layout is conducive to the Deformation control of workpiece 5, make to press the workpiece essence after quenching to improve a grade.Because be to assemble after split production, its manufacture difficulty reduces greatly.By this kind of frock of practical proof for the workpiece in automatic gear-box planet arrangement mechanism also particularly suitable.
Above an embodiment of the present utility model is had been described in detail, but described content is only preferred embodiment of the present utility model, can not be considered to for limiting practical range of the present utility model.All equalization variations of doing according to the utility model application range and improvement etc., within all should still belonging to patent covering scope of the present utility model.
