The utility model discloses stable in structure, the installation and the change of convenient tensile head have made things convenient for master worker's operation widely, have improved work efficiency.
Description
Technical field
The utility model relates to a kind of sucker rod open-close type stretching straightener.
Background technology
At present, in the manufacturing of sucker rod, often need to carry out stretching stretching alignment process to sucker rod, the structure of existing stretching stretching is varied, but most of complex structure, installing/dismounting is inconvenient, and when normal use, the gland structure of stretching stretched portion can produce distortion under long working, so just need often to change fixing head, but the gland structure of stretching stretching during design is changed inconvenient, and troublesome poeration, affects stretching draw efficiency.
Utility model content
The utility model, in order to solve the above-mentioned deficiency of prior art, proposes a kind of sucker rod open-close type stretching straightener.
In order to solve the problems of the technologies described above, the utility model is by the following technical solutions: a kind of sucker rod open-close type stretching straightener, comprise support and a pair drawing mechanism being arranged on support both sides, described drawing mechanism comprises rack-mount line of slide rail, stretching shaft bar and hydraulically extensible cylinder, described line of slide rail is provided with sliding seat, the bottom of described sliding seat has the chute of coupling line of slide rail, and the top of this sliding seat is provided with stretching head mount pad, the inside of described stretching head mount pad has threaded mounting hole, the stretching head of a Y type is provided with in described threaded mounting hole, the front end of described stretching head has a pair can fix the duckbill snap close of sucker rod by elastic compression, the rear portion of stretching head is provided with the stud of Matching installation in threaded mounting hole, the outer of described duckbill snap close is leaned to one side in skewed, and a locking nut is installed in the outside of duckbill snap close with it, described locking nut is provided with handle.
Preferably, described support is provided with hydraulic system, described hydraulic system connects the hydraulically extensible cylinder on both sides; The stretching bar of described hydraulically extensible cylinder is connected to described sliding seat.
Preferably, the inner side of described duckbill snap close is provided with the elastic-friction sheet being convenient to sting tight sucker rod.
Compared with prior art, the locking nut that the utility model adopts coordinates the structure of duckbill snap close can sting tight sucker rod securely, in conjunction with the stretching of hydraulically extensible cylinder, can to stretch stretching process to sucker rod rapidly, the sliding seat adopted and the structure of stretching head mount pad can facilitate installation and the replacing of stretching head, facilitate the operation of master worker widely, improve operating efficiency.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
Detailed description of the invention
Below in conjunction with drawings and Examples, utility model is described in detail.
As shown in Figure 1, the sucker rod open-close type stretching straightener that the utility model proposes, comprise support 1 and a pair drawing mechanism 2 being arranged on support both sides, drawing mechanism 2 comprises rack-mount line of slide rail 3, stretching shaft bar 4 and hydraulically extensible cylinder 5, line of slide rail 3 is provided with sliding seat 6, the bottom of sliding seat 6 has the chute of coupling line of slide rail 3, and the top of this sliding seat is provided with stretching head mount pad 7, the inside of stretching head mount pad 7 has threaded mounting hole 8, the stretching head 9 of a Y type is provided with in threaded mounting hole 8, the front end of stretching head 9 has a pair can fix the duckbill snap close 10 of sucker rod by elastic compression, the rear portion of stretching head 9 is provided with the stud of Matching installation in threaded mounting hole 8, the outer of described duckbill snap close is leaned to one side in skewed, and a locking nut 11 is installed in the outside of duckbill snap close with it, locking nut 11 is provided with handle 12.
Support is provided with hydraulic system 13, hydraulic system 13 connects the hydraulically extensible cylinder 5 on both sides.The stretching bar 14 of hydraulically extensible cylinder 5 is connected to sliding seat 6.
The inner side of duckbill snap close 10 is provided with the elastic-friction sheet 15 being convenient to sting tight sucker rod.
In the utility model, hydraulic system 13 drives the stretching bar 14 of hydraulically extensible cylinder 5 to carry out stretching operation, locking nut 11 is by the rotation at duckbill snap close, owing to being all rotate in inclined plane, and then duckbill snap close slowly presses down toward in the sucker rod that is critical, the effect of adding elastic-friction sheet 15 can lock sucker rod securely, helps it to complete stretching alignment operation.
Above-described embodiment only have expressed several embodiment of the present utility model, and it describes comparatively concrete and detailed, but therefore can not be interpreted as the restriction to the utility model the scope of the claims.It should be pointed out that for the person of ordinary skill of the art, without departing from the concept of the premise utility, can also make some distortion and improvement, these all belong to protection domain of the present utility model.Therefore, the utility model patent and protection domain should be as the criterion with appended claims.
