Abstract
The utility model discloses a hard metal countersink compound cutter for hydraulic parts, which is composed of a taper shank and a cutter head, wherein, the cutter head comprises a broad, a countersinking cutter and a reaming; two or more than two cutter blades which are symmetrical or not symmetrical and are arranged and fixedly welded on the periphery of a cutter body. The utility model is characterized in that each hard metal blade surface of the broad, the countersinking cutter and the reaming is a mirror surface, and the surface roughness of the mirror surface can reach to Ra< 0.01 mum (>*14). The utility model can effectively reduce the manufacture cost of hydraulic parts, and enhance the machining accuracy of hydraulic parts.
Description
The utility model relates to a kind of production and processing hydraulic part and cuts with scissors compound cutter with carbide alloy expansion ream.
Produce hydraulic part at present and cut with scissors compound cutter with carbide alloy expansion ream, its cutter head surface roughness has only Ra 〉=0.4～0.8 μ m, behind this cutter machining hole, workpiece surface roughness has only about Ra=1.6 μ m, will process with the equipment for grinding mill if workpiece requires high slightly, the workpiece cost improves, influence production efficiency, for hydraulic part valve body, workpiece such as valve, because the restriction of structure and shoulder hole, general processing with mill also is difficult to the surface quality and the required precision that reach desirable.
The purpose of this utility model provides a kind of high efficiency, high-precision hydraulic part expands ream with carbide alloy and cuts with scissors compound cutter, when this cutter is realized reaming, spot-facing, fraising in the time processing process, can very easily make the endoporus of workpiece to be machined reach Ra＜0.32～0.1 μ m (＞ 9～ 10), removed the mill manufacturing procedure from, enhanced productivity.
The purpose of this utility model is achieved in that it is made of taper shank and cutter head.Cutter head includes cornish bit, spot facer and fraising cutter, and the front and back of spot facer are respectively equipped with taper and circular spot-facing blade.Be respectively on cornish bit, spot facer and the fraising cutter symmetry or asymmetrical two or more blades aligned and be welded in admittedly cutter hub around.Its key technology is that each carbide chip blade face is minute surface on cornish bit, spot facer and the fraising cutter, and surface roughness reaches Ra＜0.01 μ m (＞ 14).
Below in conjunction with drawings and Examples structure of the present utility model is further described in detail.
Fig. 1 is the utility model structural representation;
Fig. 2 is the utility model cornish bit A-A profile;
Fig. 3 is the utility model spot facer B-B profile;
Fig. 4 is the utility model fraising cutter C-C profile;
Fig. 5 is the utility model spot facer D-D profile;
Fig. 6 is the utility model blade work location drawing.
Referring to accompanying drawing, the utility model is made of taper shank 1 and cutter head.Cutter head includes cornish bit 7, spot facer 8,9 and fraising cutter 4, and the front and back of spot facer 8,9 are respectively equipped with taper and circular spot-facing blade 2,3 and 5,6.Be respectively on cornish bit, spot facer and the fraising cutter symmetry or asymmetrical two or more blades aligned and be welded in admittedly cutter hub 13 around, its key technology is that the spot-facing blade 2,6 that is provided with previously on the spot facer 8,9 is the taper spot facer, and the spot-facing blade 3,5 of back is circular spot facer.Each carbide chip blade face is that cutting cone sword face 12, front cutting edge face 22, all rear knife edge faces 21 of knife face 25,26 and fraising cutter 4 is minute surface behind the cutting cone sword face 11,14, front cutting edge face 18,20,24,27, all rear knife edge faces 17,19,23,28, end sword of cutting cone sword face 10, front cutting edge face 15, all rear knife edge faces 16 and the spot facer 8,9 of cornish bit 7 on cornish bit 7, spot facer 8,9 and the fraising cutter 9, and surface roughness reaches Ra＜0.01 μ m.
Each blade surface of the present utility model is minute surface, surface roughness reaches Ra＜0.01 μ m (＞ 14), so blade is very sharp, no sawtooth defective, no circular arc occurs, be used for the hole and add man-hour, as select suitable cooling fluid, and can make surface of the work reach Ra＜0.04～0.02 μ m (＞ 12～ 13), need not increase equipment, repeatedly processing can reach desirable surface roughness.
Good effect of the present utility model is mainly manifested on its technology advanced, economically reasonable, has height The processing and forming characteristics of efficient, high reliability. Can effectively reduce the manufacturing cost of hydraulic pressure spare, improve liquid The processing precision of casting die satisfies need of production.
