Abstract
The utility model relate to a kind of for pin-and-hole shaping rush tool, be integrated the body of rod of cutting forming, guide section, push broach section, extruded segment and gripping section is followed successively by bottom by top, guide section comprise be convenient to bore into tip and the tapered rod that play the guiding role, push broach section is provided with frustum wide at the top and narrow at the bottom at least two, and extruded segment is provided with the cylinder boss at least two for extruding.Rushing tool adopts carbide alloy to make, and aluminized coating is sprayed on its surface.Compared with prior art, the tool that rushes of the present utility model is when using, and guide section ensures the position degree of pin-and-hole, and push broach section excision remainder punching, extruded segment guarantees size and surface roughness.Of the present utility model rush tool utilize rush the cutting of tool and the integration of extruding, both reduced the requirement to bottom outlet aperture, in turn ensure that the roughness of machined surface.
Description
Technical field
The utility model relates to one and rushes tool, especially relate to a kind of for pin-and-hole shaping rush tool.
Background technology
At present, the processing of pin-and-hole adopts drilling to process more.Due to the factor that machine tool accuracy and cutter are beated, the dimensional accuracy of pin-and-hole is difficult to ensure, pin bore surface roughness is low.And the too small aperture size to bottom outlet of simple compressional deformation amount requires high, push broach processing cannot ensure the roughness of machined surface.
And want to reach machining accuracy, just need to use multiple tool that rushes to coordinate realization, processing cost is high on the one hand simultaneously, makes manufacturing procedure loaded down with trivial details on the other hand, and production efficiency is low.
Utility model content
The purpose of this utility model be exactly provide to overcome defect that above-mentioned prior art exists a kind of one-shot forming, cost low, both reduce bottom outlet aperture required and ensures machined surface roughness for pin-and-hole shaping rush tool.
The purpose of this utility model can be achieved through the following technical solutions:
A kind of for pin-and-hole shaping rush tool, be integrated the body of rod of cutting forming, guide section, push broach section, extruded segment and gripping section is followed successively by bottom by top, described guide section comprise be convenient to bore into tip and the tapered rod that play the guiding role, described push broach section is provided with frustum wide at the top and narrow at the bottom at least two, and described extruded segment is provided with the cylinder boss at least two for extruding.
Described tip is 0.5 ~ 1, and the tapering of described tapered rod is 0.1 ~ 0.3.
The tapering of described frustum is 0.2 ~ 0.3.
Be the body of rod between adjacent cylinder boss, described cylinder boss diameter is 1.1 ~ 1.5 times of body of rod diameter.
Described gripping section is smooth cylindrical surface, or cuts into the plane being convenient to clamp.
The described tool that rushes adopts carbide alloy to make, and aluminized coating is sprayed on its surface.
The tool that rushes of the present utility model is when using, and guide section ensures the position degree of pin-and-hole, and push broach section excision remainder punching, extruded segment guarantees size and surface roughness.Of the present utility model rush tool utilize rush the cutting of tool and the integration of extruding, both reduced the requirement to bottom outlet aperture, in turn ensure that the roughness of machined surface.
Compared with prior art, the utility model has the following advantages and beneficial effect:
1, one-shot forming minimizing manufacturing procedure cuts down finished cost;
2, both reduced the requirement in bottom outlet aperture and the roughness ensureing machined surface.
3, material carbide surface is provided with aluminized coating raising and rushes the tool life-span, reduces and rushes tool use cost.
Accompanying drawing explanation
Fig. 1 is the structural representation rushing tool of the present utility model.
Detailed description of the invention
Below in conjunction with the drawings and specific embodiments, the utility model is described in detail.
Embodiment
A kind of for pin-and-hole shaping rush tool, as shown in Figure 1, be integrated the body of rod of cutting forming, guide section 1, push broach section 2, extruded segment 3 and gripping section 4 is followed successively by bottom by top, guide section 1 comprise be convenient to bore into tip 11 and the tapered rod 12 that play the guiding role, the tapering of most advanced and sophisticated 11 is 0.5 ~ 1, and the tapering of tapered rod 12 is 0.1 ~ 0.3.Push broach section 2 is provided with frustum wide at the top and narrow at the bottom 21 at least two, and the tapering of frustum 21 is 0.2 ~ 0.3.Extruded segment 3 is provided with the cylinder boss 31 at least two for extruding, and is the body of rod between adjacent cylinder boss 31, and cylinder boss 31 diameter is 1.1 ~ 1.5 times of body of rod diameter.Gripping section 4 is smooth cylindrical surface, or cuts into the plane being convenient to clamp.
Rushing tool adopts carbide alloy to make, and aluminized coating is sprayed on its surface.
When rushing tool use, guide section ensures the position degree of pin-and-hole, and push broach section excision remainder punching, extruded segment guarantees size and surface roughness.This rushes tool utilization and rushes the cutting of tool and the integration of extruding, has both reduced the requirement to bottom outlet aperture, and in turn ensure that the roughness of machined surface.
Above-mentioned is can understand for ease of those skilled in the art and use utility model to the description of embodiment.Person skilled in the art obviously easily can make various amendment to these embodiments, and General Principle described herein is applied in other embodiments and need not through performing creative labour.Therefore, the utility model is not limited to above-described embodiment, and those skilled in the art, according to announcement of the present utility model, do not depart from improvement that the utility model category makes and amendment all should within protection domain of the present utility model.
