The invention discloses a drill stem thickening machine, which is used for the thickening production of oil drill stems. The drill stem thickening machine comprises a horizontal four-column hydraulic press (1) and a vertical four-column hydraulic press (3), wherein a first moveable beam (1.2) of the horizontal four-column hydraulic press (1) is connected with a drill stem extruding and upsetting puncher pin (1.3), and a second moveable beam (3.2) and a lower beam (3.3) of the vertical four-column hydraulic press (3) are fixedly connected with a clamping die (5) and a thickening die (7) respectively; and the horizontal four-column hydraulic press (1) and the vertical four-column hydraulic press (3) share an integrated base (8), the top of a left beam (1.1) of the horizontal four-column hydraulic press (1) is fixedly connected with the left side of an upper beam (3.1) of the vertical four-column hydraulic press (3) by a first truss (2), while the top of a right beam (1.4) is fixedly connected with the right side of the upper beam (3.1) of the vertical four-column hydraulic press (3) by a first truss (4). In the invention, a single horizontal four-column hydraulic press and a single vertical four-column hydraulic press are rigidly combined to form the drill stem thickening machine, and thus, the vestment can be greatly reduced and the cost can be reduced.
Description
(1) Technical field [0001] The invention relates to a drill pipe thickening machine. It is used for thickening production of oil drill pipe. It belongs to the technical field of hydraulic presses. (2) Background technology [0002] Before the present invention was made, special-purpose hydraulic flat forging machines were mostly used in the thickening production of drill pipes. Hydraulic flat forging equipment requires a large investment. (3) Contents of the invention [0003] The object of the present invention is to overcome the above-mentioned disadvantages and provide a drill pipe thickening machine with small equipment investment. [0004] The object of the present invention is achieved in this way: a drill pipe thickening machine, characterized in that the thickening machine includes a horizontal four-column hydraulic press and a vertical four-column hydraulic press, and the horizontal four-column hydraulic press and the vertical four-column hydraulic press are mu...
