Abstract
The utility model relates to a novel drill shank and belongs to the drill sphere, which comprises a drill top, a drill body, a drill shoulder, and a drill tail. The utility model is characterized in that a stiffener is arranged on the drill shoulder, effectively strengthening the intensity of the drill shoulder, reducing the fracture of the drill shoulder and extending the life duration of the drill shank (the life duration of the drill shank is increased by over 20%). The utility model has the advantages of a novel structure and a high practicability.
Description
Technical field
The utility model belongs to the drilling tool field, particularly a kind of improved drill steel in shank collar position that relates to.
Background technology
The bore bit body cooperates with drill steel and constitutes drilling tool, be widely used in cut into a mountain, fields such as rock drilling, mining.Present drill steel by pricker slightly, pricker body, shank collar and bit shank form, shank collar is generally truncated cone, and along with the constantly bringing forth new ideas and popularizing of the efficient hammer drill of heavy type, the power of hammer drill is increasing, require its supporting drill steel that bigger holding capacity will be arranged, particularly the shank collar position external force of bearing is bigger.Though drill steel all has strict demand from many technologies such as selection, system pricker and heat treatments, phenomenon of rupture often occurs at the shank collar position, influences the normal use of drill steel.
Summary of the invention
The purpose of this utility model is to provide a kind of novel drill steel that improves shank collar position intensity.
The utility model is achieved in that
Novel drill steel, by pricker slightly, pricker body, shank collar and bit shank form, it is characterized in that: vertically be provided with reinforcing rib on the shank collar.
After the utility model adopts said structure, because reinforcing rib has longitudinally been set up at the shank collar position, effectively improved the intensity at shank collar position, strengthened the holding capacity at shank collar position, reduced the generation of shank collar phenomenon of rupture, thereby effectively improved the intensity of whole drill steel, prolonged the application life of drill steel, drill steel improves more than 20% application life.Have novel structure, practical effect.
Description of drawings
Fig. 1 is a kind of structural representation of the present utility model, and Fig. 2 is the left view of Fig. 1, and Fig. 3 is the right view of Fig. 1, and Fig. 4 is figure another kind of structural representation of the present utility model, and Fig. 5 is the left view of Fig. 4, and Fig. 6 is the right view of Fig. 4.
Description of drawings
In the accompanying drawing, 1 is that drill steel, 2 is that shank collar, 3 is reinforcing rib.
The specific embodiment
Below in conjunction with accompanying drawing embodiment of the present utility model is elaborated.
As shown in Figure 1, the utility model is a kind of novel drill steel 1, comprise pricker slightly, pricker body, shank collar 2 and bit shank, shank collar 2 is generally truncated cone, is vertically arranged with reinforcing rib 3 on the lateral surface of shank collar 2, reinforcing rib 3 can form with the casting of drill steel 1 consubstantiality.Reinforcing rib 3 evenly is provided with on shank collar 2, generally is divided into specifications such as 2,4,6 or 8.
Shown in Fig. 2,3, the maximum diameter that above-mentioned reinforcing rib 3 is surrounded and the greatest circle place of shank collar 2 are isometrical, and promptly reinforcing rib 3 does not exceed the greatest circle place of shank collar 2.
Shown in Fig. 4,5,6, above-mentioned reinforcing rib 3 also can promptly exceed this greatest circle place beyond the thinnest greatest circle that extends to shank collar 2 to thickness of shank collar 2.
Above-mentioned shank collar 2 also can adopt prism shape or other shape.
The reinforcing rib of setting up 3 has effectively improved the holding capacity of shank collar 2, thereby has improved the intensity of whole drill steel 1.
Claims (4)
1, novel drill steel, by pricker slightly, pricker body, shank collar (2) and bit shank form, it is characterized in that: vertically be provided with reinforcing rib (3) on the shank collar (2).
2, novel drill steel according to claim 1 is characterized in that: above-mentioned reinforcing rib (3) is set to the 2-8 root, goes up evenly at drill steel (1) to distribute.
