Abstract
The utility model discloses a cemented carbide mining bit with a horizontal line shape and high -strength, in which the bottom is provided with a gap. The utility model is characterized in that the inside of the gap is provided with a cruciform-shaped rib in which the cross section is arc-shaped. As a further improvement of the utility model, the rib and the surface of the gap are in transition connection through a fillet. 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 has breach 5 in its bottom as shown in Figure 1, but can cause its intensity to reduce, 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 high strength cemented carbide pricker sheet 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 high strength cemented carbide pricker sheet of the present utility model, its bottom is provided with breach, it is characterized in that being provided with in breach cross rib, and rib also is a carbide alloy, and 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;
As further improvement of the utility model, described rib is connected by round-corner transition with the surface of breach, can reduce stress, further increases the intensity of brazing sheet of hard alloy, increases the service life; And fillet makes the easier compression moulding of pricker sheet, is easy to processing;
In sum, the utility model can be saved certain material, be had higher intensity again, and application life is longer, and is easy to processing.

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 high strength cemented carbide pricker sheet 3, its bottom is provided with breach 1, is provided with cross rib 2 in breach 1, and the cross section of rib 2 is an arc, and rib 2 is connected by fillet R transition with the surface of breach 1; The setting of rib 2 and fillet R can significantly increase the intensity of brazing sheet of hard alloy 3, increases the service life, and is easy to processing.
