Description
Technical field
The utility model belongs to field of mechanical technique, relates to a kind of drill bit, and particularly a kind of chipless melts drill bit.
Background technology
In machining, usually need to solve the problem that is coupled to each other of thin wall type, strip type or cast workpiece, three kinds of detachable connecting modes of more typical thin-wall workpiece are arranged in the market.First kind, directly tapping in the thin-walled through hole is by the thread connection of bolt (nail) realization thin-wall workpiece.The shortcoming of this mode is that because the wall thickness deficiency of thin-wall workpiece, the ridge number is less, causes intensity, self-locking performance and the reliability of thread connection relatively poor easily.Second kind, weldering (riveting) connects an auxiliary nut in the connection holes of thin-wall workpiece, to increase the length that connects screw thread, improves linking intensity.The shortcoming of this mode is, it is loaded down with trivial details that thin-wall workpiece weldering (riveting) connects operation, and weldering (riveting) connection technology requires also higher, is easy to burn thin-wall workpiece and spot welding intensity is also not high enough.The third wears an attachment bolt on the thin-wall workpiece that two needs connect, on attachment bolt outside shimming and nut.The shortcoming of this mode is that when thin-wall workpiece was pipe fitting, nut was inconvenient to install, and outer shimming and nut can increase production process, lower efficiency, increase production cost.
In order to realize the connection of easy quick, cost-effective thin-wall workpiece, just need a kind of drill bit of design can in processing thin-walled workpiece process, utilize the material of workpiece itself to form one and can attack the cylindrical shell of making screw thread.
The utility model content
The purpose of this utility model is can't solve the above problems at existing drill bit, provides a kind of and can realize chipless in process, and can utilize the material of processing work itself to form the molten drill bit of chipless that can attack the cylindrical shell of system screw thread.
The purpose of this utility model can realize by following technical proposal: a kind of chipless melts drill bit, comprise and be used for being installed in the shank of rig and the operate portions that is used to hole, it is characterized in that, between shank and operate portions, also be provided with shoulder block, described operate portions front end has working head, described shank, operate portions and shoulder block three are for integral structure and adopt the high-melting-point hard material to make, and described operate portions does not have cutting edge.
The molten drill bit of this chipless is arranged on the rig, be used for carrying out boring to metal thin-wall workpiece, the lower surface of the thin-wall workpiece that processes by the molten drill bit of this chipless has a cylindrical shell that can be used to attack the system screw thread, and this cylindrical shell length is much larger than the thickness of metal thin-wall workpiece.The operation principle of the molten drill bit of this chipless is such, when the molten drill bit of chipless at metal thin-wall workpiece surface high speed rotary and when being subjected to downward axial compressive force, the working head and the metal material of the molten drill bit of chipless acutely rub, produce high temperature, the localized metallic material that contact with the working head of the molten drill bit of chipless is heated up redden and soften rapidly, along with axial compressive force strengthens and the feeding intensification, the operate portions of the molten drill bit of chipless and the contact area of metal material increase, heating further increases, and the processing district temperature continues to rise and redness area is enlarged.Along with axial feed and turning effort lower edge radial and axial do the thermoplasticity mobile and formation cylindrical shell of fusion solid material original in the hole at the molten drill bit of chipless.
In the molten drill bit of above-mentioned chipless, described high-melting-point hard material is the diamondite material.The molten drill bit hardness of chipless, the fusing point made by the diamondite material are all enough high.
In the molten drill bit of above-mentioned chipless, described operate portions comprises contact site one, contact site two and working head, described contact site one, contact site two and working head are one-body molded, and described contact site one is the cylinder of polygon circle, described contact site two is the centrum of polygon circle, described working head shape triangular in shape.The working head of triangle is can produce bigger heat during for processing work, and workpiece can be melted faster, and the surface is the contact site one of polygon circle and contact site two and can the easier material that workpiece is processed extrudes and form a ring neck.
In the molten drill bit of above-mentioned chipless, described shoulder block is cylindric, and described shoulder block upper end has groove.The upper surface of processed thin-wall workpiece can form a circle ring neck under the effect of this shoulder block, this is upwards to rout up because understand some material in the thin-wall metal workpiece hole in extruding, fusion process, the surface of the work that processes like this forms once circle ring neck does not need to increase in addition pad, saves cost.Shoulder block upper end has groove, and to make that the molten drill bit of this chipless is made clear angle vertical, more stable when the rig clamping, improves the precision that drill bit uses.
As another situation, in the molten drill bit of above-mentioned chipless, described shoulder block is ellipticity basically, and described shoulder block also has cutting edge.Utilize the cutting edge of ellipticity shoulder block in rotary course the molten material of routing up to be scraped back or cut, the upper surface of the thin-wall workpiece that processes under the effect of such shoulder block is smooth smooth surface.
Compared with prior art, the molten drill bit of this chipless has the following advantages:
1, the molten drill bit of this chipless adopts the diamondite material to make, and it is all enough high to make that this chipless melts the hardness of drill bit, fusing point, can be applicable to various metal thin-wall workpiece, and the scope of application is wide.
2, the operate portions of the molten drill bit of this chipless does not have cutting edge, and the workpiece that processes does not have scrap, has simplified manufacturing procedure, has improved the utilization rate of material.
3, the shoulder block of the molten drill bit of this chipless is cylindric, can make the workpiece surface that processes form a circle ring neck, need not to increase in addition pad, saves cost.
