Abstract
The utility model discloses a square-head forged piece. The square-head forged piece comprises a first disc body, a square column body and a second disc body, wherein the first disc body, the square column body and the second disc body are coaxially, integrally and sequentially arranged from bottom to top. The radius of the first disc body is larger than the diagonal length of the bottom surface of the square column body, and the diagonal length of the bottom surface of the square column body is larger than the radius of the second disc body. A round chamfer is arranged on the combination portion of the square column body and the first disc body, and a chamfer is arranged on the combination portion of the second disc body and the square column body. Preferentially, the thickness of the first disc body is larger than that of the second disc body. The square-head forged piece has the advantages that the body structure is suitable for machining square-head drills conveniently.
Description
Technical field
The utility model relates to the square toes forging.
Background technology
Oil bit is the important tool of oil drilling, the quality of its service behaviour will directly affect drilling quality, drilling efficiency and drilling cost, the square toes drill bit is a kind of in oil bit, as current square-drill is first, by square toes forging and pipe welding, formed, therefore the moulding of square toes forging directly affects the end product quality of square toes drill bit, therefore the more rational square toes forging of type body need to be arranged.
The utility model content
The purpose of this utility model is to provide a kind of square toes forging, and its type body structure is more suitable for conveniently processing the square toes drill bit.
For achieving the above object, the technical solution of the utility model is a kind of square toes forging of design, comprises coaxial one the first disc, cubic cylinder and the second disc that set gradually from down to up; The radius of the first disc is greater than the bottom surface catercorner length of cubic cylinder, and the bottom surface catercorner length of cubic cylinder is greater than the radius of the second disc; The joint portion of four directions cylinder and the first disc is provided with rounded corner; The joint portion of disc and cubic cylinder is provided with chamfering.
Preferably, the thickness of described the first disc is greater than the thickness of disc.
Advantage of the present utility model and beneficial effect are: a kind of square toes forging is provided, and its type body structure is more suitable for conveniently processing the square toes drill bit.
The accompanying drawing explanation
Fig. 1 is schematic diagram of the present utility model;
Fig. 2 is the top view of Fig. 1.
The specific embodiment
