Abstract
The invention relates to a multi-directional forging process for an oil drill rod joint. The multi-directional forging process comprises the following steps of (1) cutting barstock; (2) heating the barstock section; (3) pre-forging the barstock to make blank; (4) finally forging the pre-forged barstrock section on a multi-directional forging machine to form; and (5) punching the finally forged and formed workpiece on a punching press. The multi-directional forging process provided by the invention divides the production process into cutting, heating, pre-forging and blank-making, finally forging and forming and the like, and in the finally forging and forming step, the multi-directional forging machine is adopted to process, thus, the process is simple, the cost is reduced, and the quality of the drill rod joint is improved.
Description
Technical field
The present invention relates to a kind of joint of petroleum drill rod multiway forging technique.
Background technology
For the casting joint of traditional handicraft, the alloy bar need to be heated to the runny state that dissolves, needed heating furnace power is larger, and needed heat time heating time is longer, and the operating cost of required mobile cast was higher after heating was finished.After the cooling die sinking, casting flaw can cause yield rate lower.The inside trachoma pore that can't predict and cause because of special circumstances.And surface nearly all behind the casting all need process, and processing capacity is quite large.
Summary of the invention
The present invention provides for solving the technical problem that exists in the known technology that a kind of flow process is simple, the multiway forging technique of cost, lifting tool joint quality.
The technical scheme that the present invention takes for the technical problem that exists in the solution known technology is: a kind of joint of petroleum drill rod multiway forging technique comprises the steps the step of (1) bar cutting; (2) step that the bar section is heated; (3) the bar section is carried out the step of blocking base; (4) the bar section behind the blocking is carried out the step of finish forging at multi-directional forging press; (5) workpiece behind the finish forging is carried out the step of punching at punching press.
Advantage of the present invention and good effect are: joint of petroleum drill rod multiway forging technique of the present invention is divided into production process the steps such as cutting, heating, blocking base, finish forging, adopt multi-directional forging press to process in the finish forging step, technique is simple, the quality of cost, tool joint is improved.
Preferably: the firing equipment in the described step (2) is intermediate frequency furnace.
Preferably: the temperature that heating reaches in the described step (2) is 1150 ℃.
Preferably: the appearance profile that in the step of described step (3) blocking base, bar is processed tool joint.
Preferably: the multi-directional forging press in the described step (4) comprises vertical briquetting machine and horizontal briquetting machine, and described vertical briquetting machine is fixed workpiece, and it is compressing with workpiece that described horizontal briquetting machine produces horizontal extruding force.
Preferably: finished the transfer of bar section between described step (2) and the step (3) by reclaimer robot.
Preferably: between described step (3) and step (4) the transition operation is set, manipulator feeding from pre-forging press is positioned on the transition platform, and another manipulator feeding from the transition platform is positioned on the finish-forging press.
Preferably: between described step (4) and step (5) the transition operation is set, manipulator feeding from the finish-forging press is positioned on the transition platform, and another manipulator feeding from the transition platform is positioned on the punching press.
The specific embodiment
For further understanding summary of the invention of the present invention, Characteristic, hereby exemplify following examples and be described in detail as follows:
Joint of petroleum drill rod multiway forging technological process of the present invention is as follows:
Adopt overhead traveling crane long bar to be hung on the sawing machine sawing machine self-feeding, scale, saw material;
Bar section after the employing overhead traveling crane will cut is hung to deliver in the intermediate frequency furnace and is heated, and intermediate frequency furnace carries out constant temperature, timing heated, and the heating final temperature is 1150 °;
Adopt reclaimer robot that the bar section that heats is transferred to and carry out the blocking base on the pre-forging press, the bar section is processed the appearance profile of tool joint;
