The inching straightening machine is a horizontal type press machine which is powered by hydraulic pressure, wherein hydraulic system components such as an oil tank, an oil pump, an oil cylinder and a control valve are arranged in the inching straightening machine. The inching straightening machine is further provided with an adjustable support seat with lead screw drive as principle and a detection device used for detecting the bending degree of the end portion of the sucker rod. When the hydraulic inching straightening machine of the sucker rod works, power is supplied by a hydraulic system, and a bend position of the sucker rod is straightened by means of the three-point bending principle. The hydraulic inching straightening machine of the sucker rod is suitable for straightening of sucker rods with different diameters and different lengths, manual straightening is replaced, labor intensity is relieved, straightening accuracy is improved, and quality of the sucker rods is improved.
Description
Technical field
The utility model relates to a kind of sucker rod hydraulic pressure crawl straightener, belongs to the sucker rod special mechanical equipment.
Background technology
Sucker rod is a kind of petroleum machinery part of draw ratio super large, and flexural deformation is difficult to avoid after the heat treatment, and especially the end can only rely on follow-up alignment to satisfy the linearity requirement.Present domestic producer of the same trade has two kinds to the aligning method of rod sag distortion: a kind of is the method that original craft is knocked with copper or aluminium hammer, and labour intensity is big, and there is injury on the sucker rod surface; Another kind is to utilize common vertical press pressurization alignment, and this method is not easy to operate when material loading, blanking, and production efficiency is low, does not have checkout gear simultaneously, can not effectively judge the effect after the alignment.
Technology contents
The purpose of this utility model is to provide a kind of effectively alignment and detects sucker rod end diastrophic sucker rod hydraulic pressure crawl straightener.
Technical solution
The utility model comprises: bin, crawl straightener, bin is by stock shelf, cradle, blanking rack, stock shelf the place ahead is provided with cradle, cradle the place ahead is provided with blanking rack, cradle is provided with many group rollers, the crawl straightener is arranged in a side of bin, and the main frame body inside of crawl straightener is provided with oil pump, fuel tank and connects oil pipe; The leading section on plane is provided with oil cylinder, overflow valve, hand-operated direction valve on the main frame body, fixedly there are the universal ball seat that supports sucker rod and the checkout gear that detects sucker rod end bending in the middle part, rearward end is fixing by the adjustable rigid mount of the lead screw transmission of being made up of leading screw, bearing body, holder head and wind, and bearing body and holder head are hinged; The trapezoidal external thread rotary in the two ends of leading screw is on the contrary, and is opposite with the match trapezoidal internal thread rotation direction of bearing body of transmission of leading screw; The alignment center line of described crawl straightener is the line of centres of universal ball seat and holder head, and the alignment center line of the center line of described cradle and crawl straightener matches, and described oil cylinder center line and alignment center line are perpendicular.
Described checkout gear is dial gauge, and the gauge outfit of dial gauge is protected with steel plate.
The utility model places the sucker rod semi-finished product on the cradle, manually feeding places the crooked position of sucker rod in the middle of two holder heads, the primer fluid pressing system, the piston rod of oil cylinder stretches out and withstands on rod sag place, with the displacement of hand-operated direction valve control piston head, utilize the principle of " three-point bending " with the crooked position alignment of sucker rod.Adopt dial gauge to detect the flexural deformation of sucker rod end.
The utility model is applicable to the alignment of different-diameter, different length sucker rod, substitutes alignment manually, reduces labor intensity, and improves the precision of alignment, improves the sucker rod product quality.

The specific embodiment
The utility model stock shelf 1 the place ahead is provided with cradle 2, and cradle 2 the place aheads are provided with blanking rack 4, the side that crawl straightener 5 is arranged bin, and its position matches the center line of cradle 2 and alignment center line.Main frame body 6 inside of crawl straightener 5 are provided with oil pump 7, fuel tank 8 and connect oil pipe; The front end of the last plane steel plate of main frame body 6 is provided with oil cylinder 10, overflow valve 11, hand-operated direction valve 12, and oil cylinder 10 center lines and alignment center line are perpendicular; The rear end is fixing by the adjustable rigid mount of being made up of leading screw 14, bearing body 15, holder head 16 and wind 17 of lead screw transmission, and holder head 16 is hinged with bearing body 15; The two ends external thread rotary of leading screw 14 is to opposite (being respectively left-handed and dextrorotation), and is also opposite with the match internal thread rotation direction of two bearing bodies 15 of transmission of leading screw 14; During with wind 17 rotational lead screws 14, the direction of motion of two bearing bodies 15 is opposite, realizes that the distance between two holder heads 16 is adjustable.During bearing body 15 move toward one another, shorten the distance between two bearing bodies 15, be applicable to short crooked alignment; During the opposing motion of bearing body 15, strengthen the distance between two bearing bodies 15, be applicable to long crooked alignment.The universal ball seat 13 that supports sucker rod and the checkout gear 18 that detects sucker rod end bending are fixedly arranged on plane on the main frame body 6 in addition.Described checkout gear 18 is dial gauges, and gage outfit supports and protection with steel plate, is fixed on the last plane of main frame body 6.
Described stock shelf 1 is a steel construction support body, in order to place crooked sucker rod semi-finished product.
Described blanking rack 2 is steel construction support bodys, and seven groups of rollers 3 are installed on the last plane, and roller 3 is on same plane, same straight line.
Described blanking rack 4 is made up of four identical steel construction support bodys, in order to place the sucker rod semi-finished product after alignment is finished.
It is the forcing press of power with hydraulic pressure that crawl straightener 5 adopts horizontal.
During the utility model work, the sucker rod semi-finished product are rolled down from stock shelf 1, place on the cradle on 2 the roller 3, manually feeding places in the middle of two holder heads 16 crooked position of sucker rod, open control power supply 9 with primer fluid pressure oil pump 7, oil cylinder 10 is started working, and piston rod stretches out the crooked position that withstands on sucker rod and applies the alignment that strength realizes sucker rod.Effect after the alignment is measured with checkout gear 18, is cylindrical position, sucker rod end is extended the gage outfit place, and the body of rod overlays at universal ball seat 13 and rotates, and blanking rack 4 is put in alignment more again when qualified when the end jerk value is overproof.With the displacement of hand-operated direction valve 12 control piston heads, with the pressure of overflow valve 11 control alignments, to adapt to the alignment of differently curved degree, different size sucker rod.
