Abstract
The utility model discloses a cemented carbide mining bit with a horizontal line shape in which the bottom is a concave arc surface, which is characterized in the arc surface is provided with a cruciform-shaped rib in which the cross-section is arc-shaped With the utility model, a certain materials can be saved with higher strength, longer service life and easy processing.
Description
Technical field
The utility model relates to a kind of yi word pattern brazing sheet of hard alloy.
Background technology
Be widely used in the yi word pattern brazing sheet of hard alloy on the bore bit, initial its bottom is the plane, because of the unit price of carbide alloy higher, for saving material, reducing cost, yi word pattern brazing sheet of hard alloy after the improvement as shown in Figure 1, its bottom be the cambered surface 5 of indent, but can cause the reduction of its intensity, phenomenon of rupture easily takes place during use, has shortened the application life of pricker sheet.
The utility model content
The purpose of this utility model is the above-mentioned deficiency at prior art, and a kind of yi word pattern brazing sheet of hard alloy is provided, and it can be saved certain material, have higher intensity again, and application life is longer.
For achieving the above object, yi word pattern brazing sheet of hard alloy of the present utility model, its bottom is the cambered surface of indent, it is characterized in that being provided with on cambered surface cross rib, the cross section of rib is an arc; The setting of rib can significantly increase the intensity of brazing sheet of hard alloy, increases the service life;
In sum, the utility model can be saved certain material, be had higher intensity again, and application life is longer.
Description of drawings
Fig. 1 is the front view of existing yi word pattern brazing sheet of hard alloy.
Fig. 2 is a front view of the present utility model.
Fig. 3 is the upward view of Fig. 2.
Fig. 4 is the A-A sectional view of Fig. 2.
The specific embodiment
The utility model is described in further detail below in conjunction with accompanying drawing.
By Fig. 2, Fig. 3 and shown in Figure 4, this yi word pattern brazing sheet of hard alloy 3, its bottom is the cambered surface 1 of indent, is provided with cross rib 2 on cambered surface 1, the cross section of rib 2 is an arc; The setting of rib 2 can significantly increase the intensity of brazing sheet of hard alloy 3, increases the service life.
