Description
Technical field
The utility model relates to engine crankshaft curved bar quenching technology, is related specifically to a kind of splitting cnginc bent axle curved bar quenching line circle.
Background technology
Engine crankshaft curved bar adopts high frequency or medium frequency quenching mode to heat-treat it usually, prior art engine crankshaft curved bar quenching coil is integral type structure, namely hollow copper tubing is adopted to make quenching coil, on the one hand as electrically-conductive coil, on the one hand as the pipeline spraying cooling fluid.Therefore, quenching coil needs to pass into high frequency or intermediate frequency big current, meanwhile, needs to pass into cooling fluid in pipe.Due to be in cooling fluid and electric current for a long time effect under, under namely coil is in the effect colded and heat succeed each other of heating or Quench for a long time, coil is easy to distortion or damages, and has a strong impact on the work-ing life of coil.In addition, because the shape of the coil that quenches is annular, is generally at conplane two circles, has multiple corner, and the inner side of inner ring is provided with spout hole.Employing copper pipe makes, and difficulty is comparatively large, and cost of manufacture is higher, changes quenching coil frequently, adds production cost.Obviously, prior art engine crankshaft curved bar quenching coil also exists easily distortion or damages, and cost of manufacture is higher and need the problems such as frequent replacing.
Summary of the invention
There is easily distortion for solving existing prior art engine crankshaft curved bar quenching coil or damage, cost of manufacture is higher and need the problems such as frequent replacing, the utility model proposes a kind of splitting cnginc bent axle curved bar quenching line circle.The utility model splitting cnginc bent axle curved bar quenching line circle comprises upper and lower two-layer, and upper strata is the water jet standpipe that internal diameter is identical with quenching coil inner ring, and lower floor is at the conplane quenching coil be made up of two circles; Described water jet standpipe is made up of half circle that two are not connected, the inner side of each half circle is provided with spout hole, outer middle side part is provided with the interface connecting cooling fluid transfer line, and the bottom of half circle is provided with and supports and be fixedly connected with quenching coil inner ring top by supporting; Described quenching coil inner ring does not arrange spout hole.
Further, the quenching coil of the utility model splitting cnginc bent axle curved bar quenching line circle is solid copper wire.
Further, the water jet standpipe of the utility model splitting cnginc bent axle curved bar quenching line circle is copper pipe, steel pipe or plastics tubing.
The Advantageous Effects of the utility model splitting cnginc bent axle curved bar quenching line circle realizes conduction and spraying function by quenching coil and water jet standpipe respectively, avoids the water flowing energising of quenching coil and cold and heat succeed each other, and makes it be not easy distortion or damage.In addition, quenching coil can adopt solid copper wire producing, reduces cost of manufacture on the one hand, extends work-ing life on the other hand.And adopt copper pipe, steel pipe or plastics tubing to make water jet standpipe, can cost of manufacture be reduced equally and increase the service life.
Accompanying drawing explanation
Accompanying drawing 1 is the schematic three dimensional views of prior art engine crankshaft curved bar quenching coil;
Accompanying drawing 2 is the schematic three dimensional views of the utility model splitting cnginc bent axle curved bar quenching line circle.
Below in conjunction with the drawings and specific embodiments, the utility model splitting cnginc bent axle curved bar quenching line circle is further described.
Embodiment
Accompanying drawing 1 is the schematic three dimensional views of prior art engine crankshaft curved bar quenching coil, as seen from the figure, prior art engine crankshaft curved bar quenching coil is integral type structure, namely adopts hollow copper tubing to make quenching coil, on the one hand as electrically-conductive coil, on the one hand as the pipeline spraying cooling fluid.Therefore, quenching coil needs to pass into high frequency or intermediate frequency big current, meanwhile, needs to pass into cooling fluid in pipe.Due to be in cooling fluid and electric current for a long time effect under, under namely coil is in the effect colded and heat succeed each other of heating or Quench for a long time, coil is easy to distortion or damages, and has a strong impact on the work-ing life of coil.In addition, because the shape of the coil that quenches is annular, is generally at conplane two circles, has multiple corner, and the inner side of inner ring is provided with spout hole.Employing copper pipe makes, and difficulty is comparatively large, and cost of manufacture is higher, changes quenching coil frequently, adds production cost.Obviously, prior art engine crankshaft curved bar quenching coil also exists easily distortion or damages, and cost of manufacture is higher and need the problems such as frequent replacing.
Accompanying drawing 2 is the schematic three dimensional views of the utility model splitting cnginc bent axle curved bar quenching line circle, and in figure, 1 is quenching coil, and 2 is water jet standpipe.As seen from the figure, the utility model splitting cnginc bent axle curved bar quenching line circle comprises upper and lower two-layer, and upper strata is the water jet standpipe 2 that internal diameter is identical with quenching coil inner ring 1, and lower floor is at the conplane quenching coil 1 be made up of two circles; Described water jet standpipe 2 is made up of half circle that two are not connected, the inner side of each half circle is provided with spout hole, outer middle side part is provided with the interface connecting cooling fluid transfer line, and the bottom of half circle is provided with and supports and be fixedly connected with quenching coil 1 inner ring top by supporting; Described quenching coil 1 inner ring does not arrange spout hole.For convenience of making and improving work-ing life, the quenching coil of the utility model splitting cnginc bent axle curved bar quenching line circle adopts solid copper wire to make.Meanwhile, water jet standpipe adopts copper pipe, steel pipe or plastics tubing to make.The conducting function of quenching coil is separated with spraying function by the utility model splitting cnginc bent axle curved bar quenching line circle, quenching coil and water jet standpipe is adopted to realize conduction and spraying function respectively, avoid the water flowing energising of quenching coil and cold and heat succeed each other, making it be not easy distortion or damage.And quenching coil does not need water flowing function after being separated, solid copper wire producing quenching coil can be adopted, not only reduce manufacture difficulty, also extend work-ing life simultaneously, reduce cost of manufacture.Equally, owing to not needing loaded current to pass through, water jet standpipe also can adopt intensity higher but the steel pipe manufacturing that electroconductibility is bad, can significantly improve work-ing life; Or adopt and make the bad plastics tubing making of easily same electroconductibility.
The Advantageous Effects of obvious the utility model splitting cnginc bent axle curved bar quenching line circle realizes conduction and spraying function by quenching coil and water jet standpipe respectively, avoids the water flowing energising of quenching coil and cold and heat succeed each other, and makes it be not easy distortion or damage.In addition, quenching coil can adopt solid copper wire producing, reduces cost of manufacture on the one hand, extends work-ing life on the other hand.And adopt copper pipe, steel pipe or plastics tubing to make water jet standpipe, can cost of manufacture be reduced equally and increase the service life.
