The invention relates to a puncher pin centre adjustable device of a drill stem thickening machine, which is used for the thickening production of oil drill stems. The puncher pin centre adjustable device of the drill stem thickening machine comprises a horizontal puncher pin (5), a puncher pin tail base (3) and a moveable beam (1) of a horizontal pressure. The puncher pin centre adjustable device of the drill stem thickening machine is characterized in that: a slot-hole T shaped pin groove (3.1) is formed on the puncher pin tail base (3) in a vertical direction; a T-shaped mounting pin groove (1.1) is formed on the moveable beam (1) of the horizontal press in a horizontal direction; and a mounting screw (2) having a T-shaped block passes through the slot-hole T shaped pin groove (3.1) and the T-shaped mounting pin groove (1.1) to fix the puncher pin tail base (3) on the movable beam (1) of the horizontal press. The puncher pin centre adjustable device of the drill stem thickening machine can make the installation and the modulation easy and improve the installation precision of die centering.
Description
(1) Technical field [0001] The invention relates to a drill pipe thickening machine, in particular to a punch center adjustable device of the 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] Ensuring that the center of the thickening die of the drill pipe thickening machine is consistent with the center of the punch is the basic requirement of the thickening process. This puts forward strict specifications for the installation accuracy of the equipment, which is a technical difficulty in the process of equipment installation and debugging. In the past, the installation and fixation between the tailstock of the punch and the movable beam of the horizontal press was fixed by the screw thread and the centering method of the stop. It is very difficult to adjust the centering of the mold in this way of fixing. (3) Contents of the invention [0003...
