Abstract
The utility model discloses a welding type hard alloy point molding spotfacing tool which is characterized in that a cutter body and a hard alloy cutting edge are provided; the cutter body is a hollow tubular structure; the cutter body is provided with a blocking-out step used for welding the hard alloy cutting edge; the hard alloy cutting edge is welded in the blocking-out step on the cutter body; the pipe wall at the rear side of the cutter body is provided with a connecting threaded hole used for connecting the spotfacting tool and a rotary handle into a whole; the pipe wall of the cutter body is provided with a locating key slot. The welding type hard alloy point molding spotfacing tool has the advantages of reasonable structure, convenient use, low cost, long service life, high work efficiency, etc., can increase the rigidity and the service life of the spotfacting tool, improve the production efficiency and lower the degree of roughness of the processed surface.
Description
Technical field
The utility model relates to field of machining, is specifically related to a kind of welded type carbide alloy ripple mouth moulding countersink.
Background technology
Along with the develop rapidly of society's science and technology, lathe obtains application more and more widely in China's mechanical processing industry.Simultaneously, solve the insoluble many processing difficult problems of machine tool, improved machining accuracy and production efficiency, processing technology and Tool Design have been proposed many new, higher requirements.For these advanced equipment are played a role better, must address these problems.
Tubular workpiece in the existing boiler for producing industry needs ream to go out many stepped holes so that the connection between the pipe fitting on it.In the boiler processing industry, when processing step hole, the special-purpose ream head that makes for a long time is that a kind of monoblock type high-speed tool steel (high-speed steel) is made both at home and abroad, and the price comparison of high-speed steel is expensive, if whole cutter hub is all made of high-speed tool steel, not only involve great expense, and efficient is not high, because the hardness of high-speed tool steel only is that using soon, cutting edge is is just worn and torn about the HRC60 degree, thereby cause very big waste, and the roughness in the hole that goes out of ream is very high.
The utility model content
The purpose of this utility model is to overcome above-mentioned technical deficiency, a kind of welded type carbide alloy ripple mouth moulding countersink is provided, this welded type carbide alloy ripple mouth moulding countersink has rational in infrastructure, easy to use, advantages such as cost is low, the life-span is long, operating efficiency height, can increase the hardness and the service life of countersink, enhance productivity, reduce the roughness of machined surface.
For reaching the foregoing invention purpose, the technical scheme that is adopted is: a kind of welded type carbide alloy ripple mouth moulding countersink is characterized in that: described welded type carbide alloy ripple mouth moulding countersink comprises cutter hub and carbide chip; Described cutter hub is a hollow tubular structures; Described cutter hub is provided with the screens step that is used to weld carbide chip; Described carbide chip is welded in the screens step on the cutter hub.
According to welded type carbide alloy ripple mouth moulding countersink provided by the utility model, it is characterized in that: the tube wall of described cutter hub is provided with and is used for being connected screw with what countersink and rotation handle of a knife connected as one.
According to welded type carbide alloy ripple mouth moulding countersink provided by the utility model, it is characterized in that: the tube wall of described cutter hub is provided with positioning spline.
Welded type carbide alloy ripple mouth moulding countersink provided by the utility model has rational in infrastructure, easy to use, advantages such as cost is low, the life-span is long, operating efficiency height, can not only increase the hardness and the service life of countersink, can also enhance productivity, reduce the roughness of machined surface.

The specific embodiment
Below in conjunction with accompanying drawing the utility model is further described:
Fig. 1 is the vertical view of the welded type carbide alloy ripple mouth moulding countersink that provides of the utility model.As shown in FIG., this welded type carbide alloy ripple mouth moulding countersink comprises cutter hub 1 and carbide chip 2.
Fig. 2 is the upward view of the welded type carbide alloy ripple mouth moulding countersink that provides of the utility model.As shown in FIG., described cutter hub 1 is a hollow tubular structures; The tube wall of described cutter hub 1 is provided with positioning spline 101.
Fig. 3 be among Fig. 1 welded type carbide alloy ripple mouth moulding countersink along the sectional structure chart of A-A line.As shown in FIG., described cutter hub 1 is provided with the screens step that is used to weld carbide chip 2; Described carbide chip 2 is welded in the screens step on the cutter hub 1; The tube wall of described cutter hub 1 is provided with and is used for being connected screw 102 with what countersink and rotation handle of a knife connected as one.
The utility model adopts at the cutting position of steel cutter hub 1 front end welding carbide chip 2, has strengthened the hardness and the cutting power of blade.Add man-hour, at first mill out the screens step of welding carbide chip 2, weld carbide chip 2 after the cutter hub heat treatment, then blade is milled to the use size of processing component at the cutting position of its blade front end.Experimental verification is cut work metal with carbide chip 2, has increased the hardness and the service life of countersink, and converted products can reach more than 4000 still can be continued to use; The stepped hole surface roughness that goes out with this countersink ream is low, can also enhance productivity greatly.Facts have proved that this countersink has very high use value, but wide popularization and application.
