Abstract
The invention relates to a combined cutter which comprises a cutter handle and a cutter body, wherein the cutter handle and the cutter body are integrally molded; chip grooves are formed in the peripheral direction of the cutter body; the cutter body comprises a reaming section and a molding section which are peripherally provided with cutting blades spaced from the chip grooves; the included angle between active faces of the cutting blades of the reaming section is 90 degrees; the outer sides of the cutting blades of the molding section are provided with a plurality of active faces. By adopting the scheme, the cutter body is provided with two sections, reaming is performed on a workpiece, and then molding is performed on the workpiece, so that cutter damage and workpiece rejection caused by directly performing hole molding on the workpiece can be avoided, the service life of the cutter is effectively improved, and the rejection rate of the workpiece is reduced; the cutting blades are arranged on the cutter body instead of directly arranging cutting edges on the cutter body, so that the problem that the cutter is directly rejected once the cutting edges of the cutter are damaged can be avoided, cutter materials are effectively saved and the processing cost is lowered.
Description
Technical field
The present invention relates to machining tool field, being specifically related to a kind of gang tool for processing hydraulic oil pump seat.
Background technology
At present, the processing technology of processing hydraulic oil pump seat is comparatively complicated, and production efficiency is low, and benefit is not high.Need in process to adopt multiple cutter, the repeatedly installation tool setting of multiple cutter can cause accuracy error.Moreover cutter is sharp not, its cutting edge is stressed comparatively large in the process of cutting, and easily occurs breaking, is unfavorable for normally carrying out of production.In addition, if the processing of hydraulic oil pump seat exists flaw, just make troubles for installing corresponding parts, hydraulic oil pump seat even can be made to scrap.
Summary of the invention
For the problems referred to above, the object of this invention is to provide the simple gang tool of a kind of structure.
Realize technical scheme of the present invention as follows:
A kind of gang tool, comprise handle of a knife and cutter hub, described handle of a knife and cutter hub one-body molded, on cutter hub, circumference arranges chip area, described cutter hub comprises reaming section and profiled section, reaming section and profiled section are all circumferentially provided with the blade of setting alternate with described chip area, the sword face of the blade of reaming section and angle is 90 °, have some sword faces outside the blade of profiled section.
Further, the sword face of the blade of described profiled section comprises little sword face, twolip face and vertical sword face.
Further, described little sword face and vertical sword face and cutter hub axis being parallel, wherein a sword face and the cutter hub axis being parallel in twolip face, another sword face and cutter hub axes normal.
Further, between described little sword face and twolip face, twolip face and vertically inclined plane transition between sword face, be respectively the first inclined plane and the second inclined plane, first inclination face length R1 is 1.5mm, it is 15 ° with cutter hub axis angle α 1, second inclination face length R2 is 2mm, is 20 ° with cutter hub axis angle α 2.
Have employed above-mentioned scheme, cutter hub is arranged to two-part, first reaming is carried out to workpiece, again processing and forming is carried out to workpiece, avoid and directly hole forming processing carried out to workpiece and cause scrapping of the impaired of cutter and workpiece, effectively improve cutting-tool's used life, reduce the scrappage of workpiece; Change the direct cutting edge that arranges on cutter hub in the past to transfer to arrange blade on cutter hub, avoid the impaired cutter of Tool in Cutting sword and just directly scrap, effectively saved cutter material, cut down finished cost.

In figure, 1 is handle of a knife, and 2 is cutter hub, and 3 is chip area, and 4 is little sword face, and 5 is twolip face, and 6 is vertical sword face, and 7 is the first inclined plane, and 8 is the second inclination, and 9 are, 10 is spacing preiection
Detailed description of the invention
Below in conjunction with the drawings and specific embodiments, the invention will be further described.
Embodiment 1:
See Fig. 1 and 3, a kind of gang tool, comprises handle of a knife 1 and cutter hub 2, handle of a knife and cutter hub one-body molded, shank diameter d is (20-0.015) ~ (20-0.002) mm, and long L is 50mm, and the long L1 of cutter hub is 65mm.On cutter hub, circumference arranges chip area 3, and the transition of chip area afterbody arc surface is also crossing with the outer circumference surface of cutter hub gradually.Cutter hub comprises reaming section and profiled section, reaming section and profiled section are all circumferentially provided with the blade of setting alternate with described chip area, blade equal thickness.The sword face of the blade of reaming section and angle is 90 °, outer diameter D 1 size is (25.6-0.01) ~ (25.6+0.01) mm.There is outside the blade of profiled section little sword face 4, twolip face 5 and vertical sword face 6, little sword face and vertical sword face all with cutter hub axis being parallel, little sword face external diameter is equal with cornish bit external diameter, outer diameter D 2 size in vertical sword face is 37 ~ (37+0.1) mm, wherein a sword face and the cutter hub axis being parallel in twolip face, and axial length L 2 is 11mm, another sword face and cutter hub axes normal, the large D3 of its external diameter is little is (34.6-0.01) ~ (34.6+0.01) mm, internal diameter D4 size is 26.825mm, and the distance L3 of this sword face and cutter hub end face is 35mm.Between little sword face and twolip face, twolip face and vertically inclined plane transition between sword face, amount inclined plane is respectively the first inclined plane and the second inclined plane, the long R1 of first inclined plane 7 is 1.5mm, it is 15 ° with cutter hub axis angle α 1, the long R2 of second inclined plane 8 is 2mm, is 20 ° with cutter hub axis angle α 2.
Cutter hub is arranged to two-part, first by the reaming section of cutter, reaming is carried out to workpiece, by profiled section, processing and forming is carried out to workpiece again, avoid and directly hole forming processing carried out to workpiece and cause scrapping of the impaired of cutter and workpiece, effectively improve cutting-tool's used life, reduce the scrappage of workpiece.Change the direct cutting edge that arranges on cutter hub in the past to transfer to arrange blade on cutter hub, avoid the impaired cutter of Tool in Cutting sword and just directly scrap, effectively saved cutter material, cut down finished cost; Blade adopts welding manner to be connected with cutter hub, and the impaired rear direct more allowing blade replacement of blade, improves production efficiency; The described parameter of blade, plays and leads and participate in cutting, ensure processing work surface accuracy.Workpiece one-shot forming after profiled section processing, avoids the accuracy error adopting multiple cutter to cause, improves production efficiency.
Embodiment 2:
