Abstract
The invention relates to high-frequency quenching processing method of an automobile transmission shaft flange. The method is characterized by comprising the processing steps of workpiece clamping, heating and water cooling. According to the processing method provided by the invention, a workpiece transmission shaft flange is clamped on a high-frequency quenching machine tool; upper and lower inductance coils are arranged on a workpiece excircle and sequentially opened for heating; the workpiece excircle is uniformly heated up and down; water is injected into an internal hole of the workpiece so that heat that is conducted when heating the excircle can be adsorbed; an internal wall is cooled so as to prevent the internal hole from being in a thermoplastic state and then reduce shrinkage deformation of the internal hole; and the shrinkage of the internal hole is only 0.02-0.04 millimeters and one tenth of the traditional method. The invention has the advantages of stable quenching quality and convenience for operation.
Description
Technical field
The present invention relates to the quenching technology in a kind of mechanical workout, particularly a kind of vehicle transmission axial flange high-frequency quenching treatment process.
Background technology
The spline endoporus of vehicle transmission axial flange is connected with the automobile axle main reduction gear, and the minimum position of its outside diameter needs high-frequency quenching to strengthen its hardness.Traditional quenching method is that ruhmkorff coil is installed at workpiece quenching position, and workpiece is heated and the cooling of spraying water from bottom to top continuously, because outer wall is met cold fast contraction, compressing still is in the spline endoporus shrinkage strain of thermoplastic state, and product percent of pass is low.
Summary of the invention
The objective of the invention is in order to overcome above-mentioned weak point, and provide a kind of workpiece deformation little, stable in quenching quality, easy to operate vehicle transmission axial flange high-frequency quenching treatment process.
For achieving the above object, the concrete treatment process of the present invention's employing is as follows:
1, clamping workpiece: on the positioning rotating shaft of high-frequency quenching machine water wheels rotor, install the positioning seat of a vertical section additional for " ten " shape, be inserted in the rotation blind hole of positioning seat bottom the positioning rotating shaft upper end, insert in the spline endoporus at the minimum position of workpiece transmission shaft flange outside diameter after being inserted in gasket the positioning seat upper end, on the cylindrical at the minimum position of transmission shaft flange outside diameter upper and lower ruhmkorff coil is installed respectively.
2, heating: in the spline endoporus of workpiece transmission shaft flange, fill with water, open the water valve of high-frequency quenching machine, impact the water wheels rotor banding and start building to open upper and lower ruhmkorff coil heating successively after part transmission shaft flange rotates together.
3, water-cooled: be heated to the minimum position of workpiece transmission shaft flange outside diameter cylindrical and stop heating when temperature required, take off workpiece transmission shaft flange rapidly and put into water and cool off.
The present invention installs upper and lower ruhmkorff coil and opens heating successively owing to adopt above treatment process on the excircle of workpiece, excircle of workpiece is upper and lower to be heated evenly.Water filling in the workpiece endoporus, the heat of conduction in the time of can absorbing the cylindrical heating, cooled inner wall, prevent that endoporus is in the thermoplastic state, thereby reduce the endoporus shrinkage strain that the endoporus shrinkage only is 0.02～0.04 ㎜, be 1 ∕ 10 of traditional method, stable in quenching quality, easy to operate.
Description of drawings
Fig. 1 is the clamping workpiece structural representation.
Embodiment
Now in conjunction with the accompanying drawings shown in the clamping workpiece structure the present invention is made detailed description.
1, on the positioning rotating shaft 2 of high-frequency quenching machine water wheels rotor 1, installs the positioning seat 3 of a vertical section additional for " ten " shape, be inserted in the rotation blind hole 4 of positioning seat 3 bottoms positioning rotating shaft 2 upper ends, positioning seat 3 upper ends are inserted in gasket 5 backs and are inserted in the spline endoporus 7 at the minimum position of workpiece transmission shaft flange 6 outside diameters, on the cylindrical at the minimum position of transmission shaft flange 6 outside diameters upper and lower ruhmkorff coil 8,9 are installed respectively.
2, in the spline endoporus 7 of workpiece transmission shaft flange 6, fill with water, open the water valve of high-frequency quenching machine, after impact water wheels rotor 1 drive workpiece transmission shaft flange 6 rotates together, open upper and lower ruhmkorff coil 9,8 heating successively.
3, be heated to the minimum position of workpiece transmission shaft flange 6 outside diameters cylindrical and stop heating when temperature required, take off workpiece transmission shaft flange 6 rapidly and put into water and cool off.
