Abstract
The utility model relates to a tumbling device for piercing plugs for producing seamless steel pipes. The tumbling device comprises a driving motor, a transmission mechanism, a reducer, a shaft coupling and a tumbling cylinder, wherein the driving motor is connected with the reducer through the transmission mechanism; the output shaft of the reducer is connected with the main shaft of the tumbling cylinder through the shaft coupling; the other end of the main shaft of the tumbling cylinder is mounted on a bearing support through a bearing; and a material hole with a seal cover is formed on the tumbling cylinder. The tumbling device provided by the utility model can greatly eliminate the internal stress of the piercing plugs and effectively reduce the incidence of checking phenomenon of the piercing plugs, and can be popularized and used on a large scale.
Description
Technical field
The utility model relates to a kind of press finishing apparatus, is specially a kind of press finishing apparatus of producing the perforating head that seamless steel pipe uses.
Background technology
Seamless steel pipe be a kind ofly have hollow section, periphery does not have the circle of seam or the general steel of rectangle, it is to make hollow billet with steel ingot or the solid pipe hole that wears long, and makes through hot rolling, cold rolling or cold group then.Because of its manufacturing process difference, be divided into two kinds of hot rolling and solid drawn tubes again.The production process route of solid drawn tube comprises: circular pipe blank, heating, bore a hole, take the lead, annealing, pickling, oiling, multi-pass cold-drawn, base pipe, heat treatment, aligning, flaw detection.To should need being equipped with many professional equipments by process route, comprising: perforating head.Perforating head is as the internal strain instrument, and main purpose becomes solid pipe into hollow hollow billet.Perforating head is as the key tool in the seamless steel tube production, and heated metal is surrounded during its work, and condition of work is very abominable, so the length in the quality of its quality and service life directly influences the output and the quality of steel pipe's production.At present, the seamless steel pipe perforating head that uses in China's steel pipe industry is because environment for use, selection, manufacture method and heat-treat condition difference, all there be very big differing in service life and quality, but can not satisfy the demand in market generally, it exists mainly that defective has be full of cracks, the nose that collapses, abrasion etc., and wherein be full of cracks is relevant with internal stress.
Summary of the invention
Technical problem to be solved in the utility model is at above-mentioned the deficiencies in the prior art, and a kind of press finishing apparatus of producing the perforating head that seamless steel pipe uses is provided, and the internal stress that it can eliminate perforating head greatly effectively reduces the generation of perforating head crack performance.
For addressing the above problem, the technical solution adopted in the utility model is: a kind of press finishing apparatus of producing the perforating head that seamless steel pipe uses, and it comprises drive motors, transmission mechanism, reductor, shaft coupling, cylinder; Described drive motors links to each other with reductor by transmission mechanism, and the output shaft of described reductor links to each other with the main shaft of cylinder by shaft coupling, and the other end of drum spindle is installed on the bearing block by bearing; Described cylinder is provided with the material hole of band capping.
In order further to reduce internal stress, the cross section of described cylinder is a polygonized structure.
As preferred embodiment of the present utility model: described cylinder cross section is pentagon, hexagon, heptagon or octagon.
Operation principle of the present utility model is: the cylinder rotation that utilizes the drive motors drive to fixedly connected with reductor, make the mutual unordered bump of perforating head and mutual friction mutually that place in the cylinder, to reach the purpose of eliminating internal stress, removal surface scale and improving case hardness.The utility model is simple in structure, and is easy to use, can effectively solve the problems such as be full of cracks of perforating head.
Description of drawings
Fig. 1 is the scheme of erection of the utility model press finishing apparatus.
Fig. 2 is the A-A cutaway view of Fig. 1 intermediate roll.
Wherein: motor 1; Driving wheel 2; Follower 3; Reductor 4; Shaft coupling 5; Bearing block 6; Cylinder 7; Capping 71; Main shaft 72.
The specific embodiment
To closing drawings and Examples the utility model is further described below.
Embodiment, as accompanying drawing 1, shown in Figure 2: the utility model relates to a kind of press finishing apparatus of producing the perforating head that seamless steel pipe uses, comprises motor 1, transmission mechanism, reductor 4, shaft coupling 5, bearing block 6, cylinder 7; Wherein transmission mechanism comprises driving wheel 2 and follower 3; Driving wheel 2 is installed on the output shaft of motor 1 and is connected with belt with follower 3 on being installed in reductor 4 power shafts, and the output shaft of reductor 4 links to each other with an end of drum spindle 72 by shaft coupling 5; And the other end of drum spindle 72 flexibly connects with rolling bearing and bearing block 6; The regular hexagon structure is adopted in the cross section of described cylinder 7; Be provided with the material mouth on cylinder 7, be used for the turnover of perforating head, the material mouth also is equipped with capping.
When the utility model was energized rotation when motor 1, head roll 7 rotations make the mutual unordered bump of perforating head that places in the cylinder 7, eliminate internal stress, and were easy to use, reliable.
