Problems solved by technology

[0003] In order to solve the problem of processing the tooth grooves of the inner hole of the steam seal ring in the prior art, the present invention selects an ordinary lathe for processing, selects a 1mm grooving knife to first cut the groove, and then uses a steam seal tooth groove forming turning tool, that is, a 15°R0.6 steam seal The gear turning tool processes the steam seal gear, but this design is full contact on three sides, the resistance is high, the cutter head is easy to break and produce a knife, damage the tool, and it is easy to cause the teeth of the steam seal ring to fall, which is easy to cause the processing tool and workpiece In order to solve the problem of loss, a processing tool and processing method for the tooth groove of the inner hole of the steam seal ring are proposed

Abstract

The invention relates to a cutter and method for machining inner hole tooth grooves of vapor sealing rings. The problems that in the prior art, when the inner hole tooth grooves of the vapor sealing rings are machined, a center lathe is selected for conducting machining, grooving is carried out with a 1 mm grooving cutter, then vapor sealing teeth are machined through a vapor sealing tooth groove molding lathe cutter, namely a 15-degree R0.6 vapor sealing tooth lathe cutter, three-face full contact is adopted in the design, the resisting power is large, a cutter head is prone to being broken, cutter stabbing is generated, the cutter is damaged, tooth inversing on the vapor sealing rings is prone to being caused, and the machining cutter and machined workpieces are prone to being lost are solved. The cutter comprises a cutter handle and a cutter head part, the cutter handle is in a cuboid shape, the cutter head part comprises a compressing block and a cutting edge part, the compressing block is in a cuboid shape, a rectangular notch is formed in one end of the cutter handle, the cutting edge part is fixedly installed in the rectangular notch of the cutter handle through the compressing block, and the cutter edge part is located on one side of the cutter handle. The cutter and method are used for machining the inner hole tooth grooves of the vapor sealing rings.

Description

technical field [0001] The invention relates to a machining tool and a machining method for inner hole tooth grooves of a steam seal ring. Background technique [0002] The ultra-thin steam seal gear material of the steam seal ring is 3Cr13-Ⅱ material technical specification 590-B / HJ409-2006 forging, and the material hardness is HB217-269. The steam seal ring is a key part of the machine. The long and short teeth of the steam seal ring are arranged alternately. The distance between the teeth is 2.5mm, the minimum width of the groove bottom is 0.983mm, the tooth depth is 6mm, and the width of the tooth tip is only 0.2mm. With a thickness of 1mm, it is easy to cause the parts to fall, the knife to be pierced, and the turning tool to be broken. And once the knife is pierced, the teeth are reversed or the turning tool is broken, the product will be scrapped. To process the seal gear, we usually process it on an ordinary lathe. We use a 1mm grooving knife to cut the groove firs...
