Abstract
The invention relates to a mechanically clamped turning tool, in particular to a mechanically clamped turning tool for a ring slot with a stepped end surface, which is suitable for various porous plate joints of components in the coal chemical industry. The mechanically clamped turning tool comprises a turning tool head and a turning tool body, of which are of a separated structure; the turning tool head comprises a front turning tool surface, a bottom, a turning tool head inner arc surface and a turning tool head outer arc surface which are machined by a linear cutting manner, and the turning tool body comprises a turning tool inner arc surface and a turning tool body adhesion surface which are machined by the linear cutting manner; and the turning tool head outer arc surface is matched with the turning tool head inner arc surface, and the turning tool body adhesion surface is matched with the bottom of the turning tool head and is fixed by a pressing block and a compression screw in a mechanically clamping manner. According to the mechanically clamped turning tool for the ring slot with the stepped end surface, which is disclosed by the invention, the strength of a turning tool blade is improved by increasing the height of the turning tool head in a direction of the ring slot of a machined assembly and by assembling the turning tool in a mechanically clamping manner so that the turning tool is prevented from being damaged in a slot turning process.
Description
Technical field
The present invention relates to a kind of mechanically-clamped turning tool, particularly relate to a kind of suitable coals chemical industry part various " orifice plate joint " step end face annular groove turnery processing mechanically-clamped turning tool.
Background technology
The orifice plate joint that Coal Chemical Industry gasification furnace membrane wall aquaporin uses a large amount of structure similar, wherein a kind of orifice plate joint step end face there is a cannelure, when lathe carries out grooving, breaking is serious, use common brazed carbide turning tool, did multiple effort, problem cannot solve always, has had a strong impact on the manufacturing schedule of product.Because the workpiece end face annular groove space of some orifice plate joints is very little, for knife face after avoiding lathe tool and finished surface of the work are interfered, lathe tool relief angle must be strengthened, cause that cutter head height is too small, intensity is too poor, thus breaking when causing grooving.Through thinking to design of part: improve edge strength and can reduce grooving breaking dramatically, and what improve edge strength may be uniquely increase cutter head height.For avoiding relief angle and finished ring groove surface to interfere, cutter head height must increase along annular groove circumferencial direction.But when adopting brazed shank tool, cutter head internal and external cambered surface is difficult to grind by hand.
Summary of the invention
The present invention is directed to above-mentioned the deficiencies in the prior art, a kind of suitable coals chemical industry part various orifice plate joint step end face annular groove turnery processing mechanically-clamped turning tool of raising edge strength of breaking when avoiding occurring recessing is provided.
Technical scheme of the present invention is achieved in that a kind of step end face annular groove mechanically-clamped turning tool, comprises cutter head and cutter hub, and described cutter head and cutter hub are Split type structure; Described cutter head comprise all processed by Linear cut mode rake face, bottom surface, cutter head intrados and cutter head extrados, described cutter hub comprises the cutter hub intrados and cutter hub binding face all processed by Linear cut mode; Described cutter head extrados coordinates with described cutter hub intrados, and described cutter hub binding face coordinates with head base surface, and by compact heap and housing screw machine clamping fixed.
Described cutter head is sickle shaped.
Described tool tip material is high-speed steel or carbide alloy.
Described cutter hub material is No. 45 steel.
The width of described cutter head narrows from its rake face gradually to its bottom surface.
The peak of described compact heap can not higher than the minimum point on described cutter head intrados.
Described cutter head also comprises by the manual cutter head arc surface ground.
The good effect that technical scheme of the present invention produces is as follows: cutter head and cutter hub adopt Split type structure, and fix lathe tool by the mode that machine presss from both sides, cutter head height increases along annular groove circumferencial direction, avoid the interference of relief angle and ring groove surface, and then improve edge strength, breaking when decreasing recessing, accelerates manufacturing schedule.Wherein, the width of described cutter head narrow gradually from its rake face to its bottom surface can effectively avoid cut time cutter head and workpiece interfere.

Detailed description of the invention
Illustrate below in conjunction with accompanying drawing and specific embodiment the invention will be further described.
As shown in Figure 1,2,3, 4, a kind of step end face annular groove mechanically-clamped turning tool, comprises cutter head 1 and cutter hub 2, and described cutter head and cutter hub are Split type structure.Described cutter head is sickle shaped, cutter head comprises cutter head intrados A-1, cutter head extrados A-2, rake face A-3, bottom surface A-4 and cutter head arc surface A-5, wherein cutter head intrados, cutter head extrados, rake face and bottom surface are all processed by Linear cut mode, cutter head arc surface is ground by manual, and is measured by sharpening sample; For when avoiding cutting, cutter head and workpiece to be machined arc surface interfere, cutter head width narrows in face on earth gradually from rake face.Described cutter hub comprises cutter hub intrados B-1 and cutter hub binding face B-2, and cutter hub intrados and cutter hub binding face are all processed by Linear cut mode.Described cutter head and cutter hub are fixed by compact heap 3 and housing screw 4, and wherein cutter head extrados matches with cutter hub intrados, and head base surface coordinates with cutter hub binding face, ensure that cutter head and each of cutter hub are fitted reliably; For when avoiding cutting, compact heap and workpiece to be machined interfere, the peak of compact heap can not higher than the minimum point on described cutter head intrados.
The width of described rake face is identical with workpiece to be machined end face ring well width, and the length of described cutter head determines according to workpiece ring groove depth, cutter hub width and wearing and tearing allowance, after causing edge wear, can carry out repeatedly sharpening in use procedure.According to the difference of workpiece to be machined material, tool tip material can adopt high-speed steel or carbide alloy, No. 45 steel modifier treatment of cutter hub material selection.
Described cutter head and cutter hub are Split type structure, and cutter head and cutter hub clamping cutter head position are all processed by Linear cut mode, again with machine folder mode by cutter head and cutter hub fastening, be combined into mechanically-clamped turning tool, cutter head height increases along the annular groove direction of cutting workpiece, avoid interfering and occur, and improve edge strength by increasing cutter head height, avoid the situation occurring breaking when turning, enhance production progress, reduce production cost, improve production efficiency.
