Description
Technical Field
The utility model belongs to oil drilling tool processing field especially relates to a special mode locking device of drilling rod body upsetter.
Background
Along with the development of an oil drilling technology, the strength requirement on an oil drill rod is higher and higher, and a large-size drill rod is a development trend, but the drill rod pipe body is difficult to manufacture, and when upsetting and thickening are carried out, a stable mold clamping force is difficult to guarantee by using a traditional hydraulic clamping method, so that large flashes on a parting surface overflow, subsequent processing is influenced, and great potential safety hazards exist. Therefore, a special mould locking device for a drill pipe body upsetting machine is developed to meet the upsetting requirement of a large-size drill pipe body.
Disclosure of Invention
In view of this, the utility model aims at providing a special mode locking device of drilling rod body upsetter aims at solving the unstable defect of hydraulic clamping method clamping force.
In order to achieve the purpose, the technical scheme is as follows:
a special mould locking device for a drill pipe body upsetting machine comprises a bracket, a hydraulic cylinder, a rack, a crank-link mechanism and a mould locking mechanism;
the hydraulic cylinder is arranged on the bracket and is connected with a rack arranged on the bracket, the rack is connected with the crank connecting rod mechanism, and the crank connecting mechanism is connected with a die locking mechanism on the upsetting machine;
the crank connecting rod mechanism comprises a gear and a connecting rod, the gear is meshed with the rack, the gear is rotatably arranged on the bracket, one end of the connecting rod is rotatably connected to a gear spoke, and the other end of the connecting rod is connected with a die locking mechanism on the upsetting machine;
the clamping mechanism comprises an upper die, a lower die and a drill pipe body, the upper die and the lower die clamp the drill pipe body, and the upper die is movably connected with one end of the connecting rod.
The utility model has the advantages that: the utility model discloses simple structure, reasonable in design, required stable compound die power when having realized the drilling rod body jumping-up is solved to make full use of crank connecting rod's dead point characteristic, has solved the technical bottleneck of jumbo size drilling rod body processing.
