Abstract
The utility model relates to special type fireproof material processing tool, in particular to a special type fireproof material hole-bottom processing cutter which comprises a cylindrical tool shank, wherein a circular ring steel plate is welded at the front end of the tool shank, eight blades are welded on the outer end surface of the circular ring steel plate, the eight blades are uniformly distributed on the outer end surface of the steel plate radially, and eight cooling liquid through holes are formed on the circular ring steel plate and between each two blades. The special type fireproof material hole-bottom processing cutter is characterized in that a ring-shaped step is formed on the outer disc of the circular ring steel plate, eight circular arc-shaped tool bits are welded around the ring-shaped step, the tool bits and the blades are arranged in a staggered manner, and the tool bits are in parallel and level with the blades in height. Compared with a conventional hole bottom plane processing milling cutter, the utility model has the advantages as follows: the processing speed is fast, the production efficiency is high, the machining precision is high, the service life is long, and the special type fireproof material hole-bottom processing cutter is mainly mounted at the numerically controlled machining center and used for processing hole bottom planes in molten steel outlet components in metallurgical industry.
Description
technical field: the utility model relates to the process tool of special refractories, baseplane, especially a kind of machining of special refractory material hole milling cutter processing.
background technology: for the molten steel outlet device in the metallurgical steel mill, mainly be to adopt special refractories to process at present, wherein have parts need carry out the fine finishining of baseplane, hole.Baseplane, existing hole finishing cutter includes the tubular handle of a knife; The front end of the handle of a knife ring steel plate that has been welded; Eight block length square blades have been welded on the outer face of ring steel plate; Eight blades are radial even distribution on the outer face of steel plate, and are having eight cooling fluid through holes on the ring steel plate between the blade in twos.We know, the place that workpiece radius is big more, and stock removal is big more; Therefore the inboard stock removal of the stock removal of outer of existing milling cutter is big, and the exterior portions easy abrasion very easily causes the workpiece machining accuracy to reduce; Surface irregularity; Cutter life is short, needs often to change blade, has a strong impact on production efficiency.
summary of the invention: the purpose of the utility model will solve exactly that existing hole plain milling cutter machining accuracy is low, and production efficiency is low, and the problem that service life is short provides baseplane, a kind of special refractories hole milling cutter processing.
The concrete scheme of
the utility model is: improve to baseplane, existing hole milling cutter processing; It has the tubular handle of a knife, the front end of the handle of a knife ring steel plate that has been welded, and eight blades have been welded on the outer face of ring steel plate; Eight blades are radial even distribution on the outer face of steel plate; And having eight cooling fluid through holes between the blade in twos on the ring steel plate, it is characterized in that: on the ring steel plate periphery, having ring-shaped step, around ring-shaped step eight the circular arc cutter heads that have been welded; Cutter head and blade interlaced arrangement, and the cutter head axial height is concordant with blade.
Blade is fan-shaped described in
the utility model, and its length equals the anchor ring width of ring steel plate.
The spacing that 3-6mm is arranged between cutter head and the blade described in
the utility model.
this practicality is owing to set up eight cutter heads of arranging along cylindrical on ring steel plate; Changed blade into sector structure simultaneously; Increased the grinding intensity of milling cutter outer surface greatly; Guarantee the planarization of baseplane, hole processing, improved machining accuracy, improved the service life and the production efficiency of cutter simultaneously.
Description of drawings:
Fig. 1 is master's (partly cuing open) view of the utility model;
Fig. 2 is the right view of the utility model.
Among
figure: 1-handle of a knife, 2-ring steel plate, 3-cooling fluid through hole, 4-ring-shaped step, 5-circular arc cutter head, 6-blade.
The specific embodiment:
are referring to Fig. 1, Fig. 2.The utlity model has tubular handle of a knife 1; The front end of handle of a knife 1 ring steel plate 2 that has been welded; On 6, eight outer faces of blade 6 of eight blades that have been welded on the outer face of ring steel plate 2, be radial even distribution, and having eight cooling fluid through holes 3 on the ring steel plate 2 in twos between the blade 6 at steel plate; Particularly: on ring steel plate 2 peripheries, have ring-shaped step 4; Around ring-shaped step 4 eight the circular arc cutter heads 5 that have been welded, circular arc cutter head 5 and blade 6 interlaced arrangement, and circular arc cutter head 5 axial heights are concordant with blade 6.
Blade 6 is fan-shaped described in
present embodiment, and its length equals the anchor ring width of ring steel plate 2.
The spacing that 3-6mm is arranged between cutter head 5 and the blade 6 described in
present embodiment, concrete spacing is 5mm.
