Description
Technical field
The present invention relates to steel pipe manufacturing field, be specifically related to a kind of adjuster for large diameter steel pipe.
Background technology
Usually, when producing larger-diameter penstock, be roll cylindrical shell with veneer reeling machine.But full circle processing is more difficult, adopts steel plate to roll semicircular cylinder, then two semicircular cylinders are spliced into full circle cylinder.But when spliced whole cylinder, two cylinder splicings often there will be cylinder dislocation, namely welding occurs that the cylinder of welding exists distortion, needs to correct the cylinder of distortion, and prior art is with flame heating, then manually knocks and corrects rising.Need after flame heated barrel to lower the temperature to it with cold water, if can not get lowering the temperature timely after cylindrical shell heating, workman is in operation, encounters the security incident that cylindrical shell can cause workman's skin burn because of carelessness.It is low to there is working (machining) efficiency in manual synchronizing, and safety coefficient is low.
Summary of the invention
The technical problem to be solved in the present invention is for prior art timing in large diameter steel pipe manufacturing process, there is the defect that working (machining) efficiency is low, safety coefficient is low, a kind of adjuster for large diameter steel pipe is provided, has and correct the feature that steel pipe efficiency is high, safety coefficient is high.
In order to solve the problems of the technologies described above, the invention provides following technical scheme: for the adjuster of large diameter steel pipe, comprise the first screw rod, second screw rod, rotating nut and two adsorbent equipments, described first screw rod and the second screw rod are all threaded with rotating nut, described adsorbent equipment comprises adsorption site and the first elastomer block, described adsorption site is provided with groove, permanent magnet is provided with in described groove, described first elastomer block and adsorption site removably connect, described first elastomer block is provided with absorption through hole, described adsorption site is provided with chute, the end of described first screw rod and the second screw rod is provided with the slide block matched with the chute on adsorption site.
Adopt the adjuster for large diameter steel pipe in this programme, comprise the first screw rod, the second screw rod, rotating nut and two adsorbent equipments, described first screw rod and the second screw rod are all threaded with rotating nut; Rotary motion nut realize the first screw rod and the second screw rod to away from or move near the direction of rotating nut.Slide block on described first screw rod and the second screw rod, play the guiding role in the process of the first screw rod and the second screw motion.Permanent magnet on described adsorption site makes adsorption site be connected with cylinder.First elastomer block avoid adsorption site and cylinders contact insecure because the inwall of cylinder is arc-shaped, only have the object consistent with the arc-shaped of cylinder inner wall could contact more firm.First elastomer block is provided with absorption through hole, is to avoid the interference of the first elastomer block to reduce permanent magnet to the adsorption effect of cylinder.The motion of chute on adsorption site to the first screw rod and the second screw rod play the guiding role.
Operation principle of the present invention and beneficial effect are: when concrete this adjuster of use, first rotary motion nut makes the first screw rod and the second screw rod all move to the direction near rotating nut, makes the length of the support bar of the first screw rod and the second screw rod composition be less than the diameter of cylinder to be corrected.Then adsorbent equipment is adsorbed on respectively the inwall of cylinder to be corrected, then rotary motion nut makes the first screw rod and the second screw rod move respectively to the direction away from rotating nut, then make the first screw rod and the second screw rod prop up cylinder to be corrected respectively, by the first screw rod and the second screw rod, cylinder is corrected.In special circumstances also using flame heated barrel, cylinder is corrected and helps out.At cylinder timing, the present invention has the advantages that rectification cylinder efficiency is high, safety coefficient is high as can be seen here.
Further, described rotating nut is provided with Anti-slip cover.Avoid, during workman's rotary motion nut, skidding occurs, Anti-slip cover increases the frictional force of workman's rotary motion nut.
Further, the length of described first screw rod and the second screw rod is equal, and described first screw rod and the second screw flight are double thread, and silk thread form shape is all identical with pitch.First screw rod and the second screw flight all adopt two-wire nut, make rotating nut when rotation, and the first screw rod and the second screw rod move dynamic very fast.First screw rod is identical with pitch with the silk dentification of the second screw rod, and convenient processing, too increases the interchangeability of the first screw rod and the second screw rod simultaneously.
Further, described chute is dovetail groove, and described slide block is dovetails.The steering capability of dovetail groove is good, and dovetail groove can bear the impact of different directions.
Further, the end of described first screw rod and the second screw rod is equipped with the second elastomer block.When second elastomer block avoids the first screw rod and the second screw rod to support cylinder, cylinder produces stressed concentrating, and makes the first screw rod and the second screw rod and cylinders contact place become plane from circular arc on the contrary, affects cylinder quality.When second elastomer block makes the first screw rod and the second screw rod support cylinder, the face uniform force that cylinder contacts with the second screw rod with the first screw rod, and there will not be the thing scratching cylinder inner wall surface.
Accompanying drawing explanation
Fig. 1 is the structural representation of the present invention for the adjuster embodiment of large diameter steel pipe.
Detailed description of the invention
Below by detailed description of the invention, the present invention is further detailed explanation:
Reference numeral in Figure of description comprises: the first screw rod 1, second screw rod 2, rotating nut 3, adsorbent equipment 4, adsorption site 5, permanent magnet 6, first elastomer block 7, second elastomer block 8, dovetail groove 9, dovetails 10, Anti-slip cover 11, cylinder 12.
