Abstract
The invention discloses a clasping roll mechanism used during seamless steel pipe production, and belongs to the field of seamless steel pipe production equipment. The clasping roll mechanism is characterized in that the bottom of a left clasping roll seat and the bottom of a right clasping roll seat are connected onto a bottom plate, each of the left clasping roll seat and the right clasping roll seat is provided with three hinge pin holes which are respectively drilled at 120-degree positions of the same circumference, the three hinge pin holes on the left clasping roll seat correspond to the three hinge pin holes on the right clasping roll seat, one of the three hinge pin holes of each clasping roll seat is arranged on the center line of a notch, three hinge pins are mounted in the three hinge pin holes of each clasping roll seat, a rocker arm is mounted at the left end of each hinge pin, clasping rolls are mounted at ends of the rocker arms, pinions are respectively mounted at right ends of the three hinge pins of each clasping roll seat, pin holes are drilled on lower portions of inner gear rings which are meshed with the three pinions of each clasping roll seat, the hinge pins arranged in the pin holes are connected with sliders, the sliders are mounted in slider guide grooves, the slider guide grooves are connected with ends of connecting rods, and the other ends of the connecting rods are connected with piston rods of hydraulic (or pneumatic) cylinders. After the hydraulic (or pneumatic) cylinders are driven, the clasping rolls can be driven to rotate, and the purpose of clasping mandrels or steel pipes is achieved. The clasping roll mechanism has the advantages that the clasping roll mechanism is simple in structure, convenient to maintain and use and suitable for small-scale production and laboratories.
Description
Technical field
The invention belongs to seamless steel pipe production field, be specifically related to armful roller mechanism in seamless steel tube production.
Background technology
Three rollers of the prior art embrace roller mechanism, and its function holds push rod or plug tightly, or hold hollow billet or hollow forging tightly, its center line coincides with rolling centerline all the time, and can conveniently turn over from rolling centerline after unclamping, its shortcoming be complex structure, spatial volume is comparatively large, requires that machining accuracy is high, with high costs.
Summary of the invention
The object of the invention is to provide a kind of armful roller mechanism of new construction, can overcome the deficiency that prior art exists.
The present invention is achieved in that as Fig. 1,2,3,4, and shown in 6, box-shaped, centre have
the bottom that roller seat 2,2' is embraced in the left and right of shape notch 6 is connected with base plate 1 respectively by bolt, embraces roller seat (2 with left and right, centered by datum mark 2') on the rolling centerline of plate face, along the circumferential direction by 120 ° of deciles, be shaped with three pin shaft holes, one of them pin shaft hole is located at
on the center line of shape notch 6, it is symmetrical that roller seat is embraced in left and right, roller seat is embraced (2'): in three pin shaft holes, be separately installed with first, second and third bearing pin 3,3', 3 for the right side ", first, second and third bearing pin 3,3', 3 " on be separately installed with first, second and third Rocker arm 4,4', 4 "; Left and right is embraced on the symmetrical rocking arm of roller seat and is provided with first, second and third armful of roller 5,5', 5 "; right side embrace roller seat is installed first, second and third bearing pin 3,3', 3 " right-hand member be separately installed with first, second and third pinion 7,7', 7 "; " ring gear 8 be meshed is arranged on the right right-hand member embracing roller seat 2' with first, second and third pinion 7,7', 7, ring gear 8 fastens by trim ring 9, and trim ring 9 is bolted to be embraced on roller seat 2' on the right side.Ring gear 8 also has notch, corresponding with the notch 6 that left and right is embraced on roller seat, the lower vertical center line of ring gear 8 has pin-and-hole, at pin-and-hole built with bearing pin 10, bearing pin 10 right-hand member is connected with slide block 11, and slide block 11 is arranged in slide block guide groove 12, can move up and down, slide block guide groove 12 is connected with the end of connecting rod 13, and the other end of connecting rod 13 is connected with the piston rod of hydraulic pressure or pneumatic cylinder.
Advantage of the present invention and good effect are that structure is simple, and energy consumption is low, maintenance and easy to adjust, safe and reliable, and low cost of manufacture, is applicable to small lot batch manufacture and laboratory use.
