Abstract
The utility model discloses a center calibrating device for a straightening roller of a steel-pipe straighter. The center calibrating device comprises a positioning plate, a measuring rod and a top end, wherein the positioning plate is an arc-shaped plate whose internal diameter matches with that of a straighter column; one end of the measuring rod is vertically connected the external arc surface of the positioning plate; the top end is a rectangular block which is connected with the other end of the measuring rod and integrated with the measuring rod; and the distance from the top of the inner arc surface of the positioning plate to the tail end of the top end is 330mm. Calibration is finished by that the center calibrating device is transversely arranged between the column and a sampling rod, the positioning plate matches with the column, distance between the top end and the sampling rod is detected by a plug gauge, and the center corresponding to the straightening roller is adjusted till the top end is tangent with the sampling rod and the plug gauge cannot be plugged in. The center calibrating device can accurately and rapidly measure the distance between the straighter column and the sampling rod, thereby improving adjusting precision and shortening adjusting time.
Description
Technical field
The utility model relates to calibration facility, more particularly, relates to a kind of pipe straightener smoothing roll center caliberating device.
Background technology
Aligning is the vital procedure of steel pipe's production, and purpose is with the materials in the tube aligning, makes it satisfy later process processing or user's requirement.Straightener is widely used in the aligning of steel pipe, straightener run to a period of time must to wearing and tearing smoothing roll change.After each replacing smoothing roll, all to arrange smoothing roll, wherein the setting of the center of smoothing roll is key link in whole straightener adjustment process, it adjusts the quality that result directly has influence on the materials in the tube aligning.
At present, mainly utilize lining bar to carry out the center adjustment to smoothing roll.Committed step for measure distance between the corresponding column of straightener and lining bar (the 330mm error is ± 0.01mm)., measure column and can only use micrometer inside caliper to the distance of lining bar apart from the control accuracy requirement according to it.But because straightener column and lining bar are right cylinder, be cambered surface with micrometer inside caliper two ends surface of contact, this has just caused middle micrometer inside caliper location difficulty, and whole measuring process length consuming time, error are large.
The utility model content
For the above-mentioned shortcoming that exists in prior art, the purpose of this utility model is to provide a kind of pipe straightener smoothing roll center caliberating device, can facilitate the center of smoothing roll to demarcate.
For achieving the above object, the utility model adopts following technical scheme:
This pipe straightener smoothing roll center caliberating device, comprise location-plate, measuring staff and top, location-plate is the circular arc plate, internal diameter and straightener column are complementary, vertical being connected of extrados of measuring staff one end and location-plate comes directly towards and is rectangular block, is connected at the other end of measuring staff, and forming one with measuring staff, the intrados top of location-plate is to coming directly towards end-to-end distance from being 330mm.
Described measuring staff is connected by screw thread with location-plate.
The internal diameter of described location-plate is 145mm, and the diameter of described measuring staff is 25mm.
The terminal surface of described top is of a size of 6mm * 20mm.
In technique scheme, pipe straightener smoothing roll of the present utility model center caliberating device comprises location-plate, measuring staff and top, location-plate is the circular arc plate, internal diameter and straightener column are complementary, vertical being connected of extrados of measuring staff one end and location-plate comes directly towards and is rectangular block, is connected at the other end of measuring staff, and forming one with measuring staff, the intrados top of location-plate is to coming directly towards end-to-end distance from being 330mm.By the center caliberating device laterally is placed between column and lining bar, and location-plate matches with column, detects distance between top and lining bar by clearance gauge, adjusts simultaneously the center of corresponding smoothing roll, until the top is tangent with lining bar, clearance gauge can't be filled in and namely complete demarcation.This center caliberating device can be measured the straightener column accurately and rapidly to the distance of lining bar, adjusts precision and shortens the adjustment time thereby improve.
Description of drawings
Fig. 1 is the schematic perspective view of center of the present utility model caliberating device;
Fig. 2 is the use view of center of the present utility model caliberating device.
Embodiment
Further illustrate the technical solution of the utility model below in conjunction with drawings and Examples.
See also shown in Figure 1, pipe straightener smoothing roll of the present utility model center caliberating device comprises the measuring staff 2 of location-plate 1, steel and comes directly towards 3, location-plate 1 is the circular arc plate, internal diameter and straightener column 4 are complementary, and vertical being connected of extrados of measuring staff 2 one ends and location-plate 1, top 3 is rectangular block, be connected at the other end of measuring staff 2, and forming one with measuring staff 2, the intrados top of location-plate 1 is 330mm to coming directly towards 3 end-to-end distances from the demarcation distance for 4, lining bar 6 on smoothing roll 5 and column.Described measuring staff 2 is connected by screw thread with location-plate 1, so can avoid employing weld and can have welding stress and be difficult for eliminating, and deforms possibly, and then affects stated accuracy.The internal diameter of described location-plate 1 is 145mm, and the diameter of described measuring staff 2 is 25mm.The terminal surface of described top 3 is of a size of 6mm * 20mm.
During use, first all smoothing roll 5 roll gap, angle are reached maximum, lining bar 6 is sent between the aligning up-down rollers; Then rise a wherein smoothing roll 5, and lining bar 6 is set on roller; The intrados of the location-plate 1 of center of the present utility model caliberating device is close on tested column 4, and the top 3 of measuring staff 2 other ends is parallel with lining bar 6 vertical direction tangent planes, from top to down near lining bar 6; Utilize the distance between clearance gauge inspection top 3 and lining bar 6 this moment, and adjust accordingly the center of smoothing roll 5; When top 3 end faces and lining bar 6 cylindricals tangent, and the clearance gauge of 0.01mm be can't insert the time, the demarcation of tested column 4 is completed; In like manner, can carry out successively the center to other columns 4 demarcates.
In sum, adopt center of the present utility model caliberating device, can measure accurately and rapidly straightener column 4 to the distance of lining bar 6, adjust precision and shorten the adjustment time thereby improve, have broad application prospects and promotional value in the pipe straightener field.
Those of ordinary skill in the art will be appreciated that, above embodiment illustrates the utility model, and be not to be used as restriction of the present utility model, as long as in connotation scope of the present utility model, all will drop in claims scope of the present utility model variation, the modification of the above embodiment.
