Abstract
The invention discloses an internal taper hole processing method of an ultra supercritical boiler secondary mixer. The traditional processing method has the disadvantages of low processing efficiency and high tool cost. The internal taper hole processing equipment of the ultra supercritical boiler secondary mixer comprises a base (2) provided with a rotary hand wheel (1), wherein the base is connected with special processing equipment (3), a cylinder body clamping device (4) and a V shape support (5), the special processing equipment is connected with a rocker rotary bed (6) provided with a motor, the rocker rotary bed is provided with a rocker head (7), an internal taper hole processing tool (8) is installed in the rocker head, and the V shape support (5) is connected with a secondary mixer cylinder body (9) to be processed. The invention is used for a boiler.
Description
Technical field:
The present invention relates to a kind of station boiler and make the field; Be specifically related to a kind of ultra-supercritical boiler secondary blender internal tapered hole process equipment and method.
Background technology:
At present, secondary mixer part in the super ultra-supercritical boiler of employing MIT art designs, all design has the inner conical pore, the manufacture method of MIT is to adopt radial drilling machine subdrilling bottom outlet, then the molding cutter of making is inserted on the drill press spindle from secondary blender stack shell inside, utilize drill press spindle to rotate up and lift, oppositely internal tapered hole is processed.There is the shortcoming that working (machining) efficiency is low, the cost of charp tool is high in this kind processing method.
Summary of the invention:
The purpose of this invention is to provide a kind of endoporus processing that utilizes special-purpose process equipment and processing method to realize secondary blender stack shell.
Above-mentioned purpose realizes by following technical scheme:
A kind of ultra-supercritical boiler secondary blender internal tapered hole processing method, boring method processing secondary blender stack shell at first routinely, line and process Φ 17 bottom outlets and the upper end bevel for welding of internal tapered hole with radial drilling machine on secondary blender stack shell.Then, secondary blender stack shell is placed on the V-type bearing, the hole of need processing is put vertically downward, secondary blender stack shell is clamped with the stack shell clamping device; The internal taper hole process tool is installed on the special processing equipment, by rotating handwheel the front end of special processing equipment is goed deep into secondary blender stack shell inside, the internal taper hole process tool is aimed at the bottom outlet that needs processing, start motor, drive the rotation of internal taper hole process tool, rotate handwheel and drive internal taper hole process tool processing secondary blender stack shell internal taper hole downwards, after processing, loosen clamping device, rotate stack shell, process next internal tapered hole as stated above, until processing all internal tapered holes.
A kind of ultra-supercritical boiler secondary blender internal tapered hole special processing equipment, its composition comprises: have the base that rotates handwheel, described base connects special processing equipment, stack shell clamping device and V-type bearing, described special processing equipment connects the rocking arm rotated bed that has motor, described rocking arm rotated bed has rocker head, described rocker head is equipped with the internal taper hole process tool, and described V-type bearing connects secondary blender stack shell to be processed.
Beneficial effect:
1. the present invention not only can improve the working (machining) efficiency of internal tapered hole, and can reduce the cost of cutter greatly.
2. the processing method of the present invention and MIT contrast, the critical boiler of the super ultra supercritical of 600MW is reduced expenses about 29.8 ten thousand yuan; The critical boiler of the super ultra supercritical of 1000MW is reduced expenses about 42.94 ten thousand yuan.
3. the present invention is used for the processing of 12 super ultra-supercritical boilers of 1000MW such as Yuhuan, Taizhou and 23 super ultra-supercritical boiler secondarys of 600MW such as Yingkou, Kan Shan blender internal taper hole, promptly reduces expenses nearly 13,000,000 yuan.
