Abstract
The utility model discloses a drill for filigree technology manufacturing. The drill comprises a drill body and is made of steel. A knocking plane is arranged at the upper end of the drill, a tip portion is arranged at the lower end of the drill, the middle of the drill is cylindrical, and the diameter of the middle is larger than the diameters of the two ends. According to the drill, the problem that the lower end of the drill is prone to breakage when the drill is frequently used is solved, the design structure is reasonable, the middle of an existing drill is thickened, meanwhile, a thread structure is arranged on the thickened part and can achieve the effects of skid resistance and breakage, and the service life of the drill is prolonged.
Description
Technical field
The utility model relates to copper part art machining tool technical field, specifically belongs to the technique making awl that wires inlay.
Background technology
Bronze, brass or copper ware art part, after integral casting forming, need to carry out in its surface welding wire, engraving processing, wire inlay.
When wiring inlay, need to by instrument, bore hammer on its surface.Boring hammer need to be through beaing many times, and existing instrument in use, easily occurs fracture at mid portion.
Utility model content
The purpose of this utility model has been to provide the technique making awl that wires inlay, solve awl and in frequent service condition lower end, easily occur the problem of fracture, project organization is reasonable, by existing awl mid portion is added to bulk processing, at thickened portion, be provided with helicitic texture simultaneously, helicitic texture can play anti-fracture effect, improves its service life.
The technical solution adopted in the utility model is as follows:
The technique of wiring inlay making awl, comprises drill body, and awl is made by iron and steel, and described awl upper end has the plane of knocking, and lower end has tip, and mid portion is cylindrical, and diameter is greater than two end portions diameter.
Described mid portion has the export-oriented threaded line of protruding.
Described mid portion is provided with the threaded line threaded engagement of rubber sleeve and intermediary outside.
Described rubber sleeve outer wall is provided with antiskid thread.
The described planar diameter of knocking is greater than the diameter that planar section is knocked in connection.
Compared with the prior art, the beneficial effects of the utility model are as follows:
The utility model, by existing awl mid portion is added to bulk processing, is provided with helicitic texture at thickened portion simultaneously, and helicitic texture can play anti-fracture effect, improves its service life; It is stressed even in use more greatly that upper end has the plane of knocking, and reaches good result of use; At mid portion, be provided with rubber sleeve and be convenient to hand by anti-skidding.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
The specific embodiment
Referring to accompanying drawing, the technique of wiring inlay making awl, comprises drill body 1, and awl 1 is made by iron and steel, awl 1 upper end has the plane of knocking 2, lower end has tip 3, and mid portion 4 is cylindrical, and diameter is greater than two end portions diameter, mid portion 4 has the export-oriented threaded line 401 of protruding, knock planar diameter and be greater than the diameter that planar section is knocked in connection, mid portion is provided with the threaded line threaded engagement of rubber sleeve 5 and intermediary outside, and rubber sleeve 5 outer walls are provided with antiskid thread 501.Helicitic texture can play effect anti-skidding and fracture, improves its service life; It is stressed even in use more greatly that upper end has the plane of knocking, and reaches good result of use.
