Description
Technical field
The utility model relates to a kind of apparatus for leveling of stainless steel welded pipe weld seam, relates in particular to the online apparatus for leveling of a kind of stainless steel welded pipe inner and outer welding, belongs to the metal manufacture field.
Background technology
Stainless steel welded pipe all is being better than stainless steel seamless pipe aspect material and the mechanical property, but stainless steel welded pipe inner and outer welding reinforcement particularly the problem of inside weld reinforcement never be well solved.Present employed method is to scrape with (inside and outside) scraper, or with (inside and outside) polishing method eliminate reinforcement, but waste time and energy and effect undesirable, this has seriously hindered the further expansion of stainless steel welded pipe application, as mainly adopting stainless steel seamless pipe in industries such as oil, chemical industry, nuclear power, boiler, food, medicine at present.
Summary of the invention
The purpose of this utility model is to provide a kind of online apparatus for leveling of stainless steel welded pipe inner and outer welding that can thoroughly remove the reinforcement of stainless steel welded pipe inner and outer welding.
The utility model is to realize above-mentioned purpose like this:
The utility model comprises hydropneumatic system, electric liquid gas automatic control system, frame, roll and base, is characterized in that the piston rod of hydraulic cylinder and the top roll roller seat of horizontal roller flexibly connect, and have the pass groove on the circumference of horizontal roller; Edger roll is installed in back in horizontal roller, and the pass groove is also arranged on the circumference of edger roll; Hydraulic cylinder, horizontal roller and edger roll all are installed on the frame; Be placed with plug in stainless steel welded pipe, plug is connected by steel wire rope with cylinder; The mobile bearing of frame places on the bearing bar of base.
In the welded tube production process, built-in plug of front port and weld seam stainless steel welded pipe up pass through horizontal roller, edger roll at the uniform velocity successively.Under the control of electric liquid gas automatic control system, frame is along with the depressed position of mobile bearing on the bearing bar of base, carry between roller position and home position reciprocating, the speed of its motion probably is 4-8 times of stainless steel welded pipe translational speed, in the reciprocating motion process of frame, horizontal roller can press down and carry the do action of roller, plug in the stainless steel welded pipe also can move, the do action that is pulled, the rightabout that moves with stainless steel welded pipe is the direction that frame is advanced, frame, the movement relation of the plug in horizontal roller and the stainless steel welded pipe is: from depressed position, horizontal roller presses down (stainless steel welded pipe is depressed into ellipse), frame is advanced, plug (with stainless steel welded pipe) backward → frame advances to and carries the roller position, horizontal roller is carried roller, plug (with stainless steel welded pipe) also backward → frame arrives reentry point, plug is (because oval stainless steel welded pipe is recovered circular by the edger roll extruding, so under the pull of steel wire effect that connects cylinder) be pulled, frame is returned depressed position, horizontal roller presses down once more, enters next circulation.
In said process because the movement velocity of frame probably be 4-8 times of the stainless steel welded pipe translational speed, so the inner and outer welding of stainless steel welded pipe by plug and horizontal roll-in more than 2 times.
The beneficial effects of the utility model are:
Use the utility model to handle the inner and outer welding of stainless steel welded pipe, can thoroughly remove the reinforcement of stainless steel welded pipe inner and outer welding, thereby expand the application of stainless steel welded pipe, solved the dissatisfactory difficult problem of stainless steel seamless pipe material and mechanical property.
Description of drawings
Fig. 1 is a schematic perspective view of the present utility model;
Fig. 2 is the position view of horizontal roller and frame in the utility model;
Fig. 3 is the position view of edger roll and frame in the utility model.
Wherein, 1 hydraulic cylinder, 2 oil pipes, 3 oil pipes, 4 piston rods, 5 frames, 6 horizontal roller, 7 pass grooves, 8 edger rolls, 9 pass grooves, 10 stainless steel welded pipes, 11 plugs, 12 bearing bars, 13 electric control boxes, 14 mobile bearings, 15 steel wire ropes, 16 bases, 17 pulleys, 18 cylinders.
The specific embodiment
Below in conjunction with accompanying drawing the utility model is further described:
Present embodiment is a preferred forms of the present utility model.
In conjunction with Fig. 1, Fig. 2 and Fig. 3, the piston rod 4 of the hydraulic cylinder 1 that is connected with the oil pipe 2,3 of hydraulic system flexibly connects with the top roll roller seat of horizontal roller 6, and pass groove 7 is arranged on the circumference of horizontal roller 6; Edger roll 8 is installed in back in horizontal roller 6, and pass groove 9 is arranged on the circumference of edger roll 8; Hydraulic cylinder 1, horizontal roller 6 and edger roll 8 all are installed on the frame 5; Be placed with plug 11 in stainless steel welded pipe 10, plug 11 is connected by steel wire rope 15 with cylinder 18; The mobile bearing 14 of frame 5 places on the bearing bar 12 of base 16.
The centre bore of horizontal roller 6 and edger roll 8 is positioned on same the horizontal line, is convenient to operation.
The radian of pass groove 7 is greater than the circumference radian of stainless steel welded pipe 10; The radian of pass groove 9 equals the circumference radian of stainless steel welded pipe 10.
The external diameter of plug 11 is more smaller than the internal diameter of stainless steel welded pipe 10, and the steel wire rope that links to each other with plug 11 is walked around pulley 17 backs and is connected with cylinder 18, is convenient to install.
When producing welded tube, built-in plug 11 of front port and weld seam stainless steel welded pipe 10 up pass through horizontal roller 6, edger roll 8 at the uniform velocity successively.Under the control of electric liquid gas automatic control system that with electric control box 13 is operating means, frame 5 is along with the depressed position of mobile bearing 14 on the bearing bar 12 of base 16, carry between roller position and home position reciprocating, the speed of its motion probably is 4-8 times of stainless steel welded pipe 10 translational speeds, in the reciprocating motion process of frame 5, horizontal roller 6 can press down and carry the do action of roller, plug 11 in the stainless steel welded pipe 10 also can move, the do action that is pulled, the rightabout that moves with stainless steel welded pipe 10 is the direction that frame 5 is advanced, frame 5, the movement relation of the plug 11 in horizontal roller 6 and the stainless steel welded pipe 10 is: from depressed position, horizontal roller 6 presses down (stainless steel welded pipe 10 is depressed into ellipse), frame 5 is advanced, plug 11 (with stainless steel welded pipe 10) backward → frame 5 advances to and carries the roller position, horizontal roller 6 is carried roller, plug 11 (with stainless steel welded pipe 10) also backward → frame 5 arrives reentry points, plug 11 is (because oval stainless steel welded pipe 10 is recovered circular by edger roll 8 extruding, so under the pulling force effect of the steel wire rope 15 that connects cylinder 18) be pulled, frame 5 is returned depressed position, horizontal roller 6 presses down once more, enters next circulation.
In said process, because the movement velocity of frame 5 probably is 4-8 times of stainless steel welded pipe 10 translational speeds, so the inner and outer welding of stainless steel welded pipe 10 has been pressed more than 2 times by plug 11 and horizontal roller 6.
