Description
Technical field
The present invention relates to pipe production line unit field, be related specifically to a kind of method that spiral steel pipe produces unit tune type lane-change.
Background technology
Spiral steel pipe production line needs to carry out production line tune type lane-change before producing steel pipe, and in general the whole process of this tune type lane-change is to produce complete beginning to first qualified steel pipe of lower a kind of specification from last root of former gauge steel pipe to terminate.The whole story of the tune type lane-change process of different steel pipe's production producers definition is slightly different.Original tune type lane-change method is: first, and technologists calculates Form-setting parameter according to the steel pipe specification that will produce, and writes tune type lane-change guiding book according to Form-setting parameter and relevant device, and is issued to Tiao Xing workshop section.This guiding book includes the work corner of all tune type lane-change, it is to avoid the situation of work corner occur omitting in tune type personnel.Secondly, Tiao Xing workshop section is according to the work corner in tune type lane-change guiding book and workload allocations to each teams and groups, and each teams and groups are not fully complete the next class that is transferred to of this work and have continued, and are fully completed until all tune type corners.Finally, each work in whole tune type lane-change will be checked by technologists, until meeting the requirements.During conventional tune type lane-change, some problem following often occurs:
1, job order is chaotic: the work item point on tune type lane-change guiding book arranges according to job order, but employee divides the work in the middle part of actual mechanical process and makees corner and carry out the most in order, easy first and difficult later or sometimes the most improper because of order, cause subsequent work cannot be carried out, affect tune type progress.
2, job task is indefinite: tune type guiding book operation corner divides not detailed, and each teams and groups personnel arrangement is unreasonable, and task is indefinite, and the phenomenon that flocks together is obvious.Uneven because of workload allocations again, more or less, self awareness and initiative are poor, and concept of time is not strong, and job schedule cannot ensure.
3, overhead traveling crane uses unreasonable: during tune type lane-change, and overhead traveling crane uses very frequent, and many posies employee is using overhead traveling crane, because not having rational job step and order, often occurs waiting during employee's operation the situation of overhead traveling crane, affects tune type progress.
4, single line operation, personnel's utilization rate is low: during tune type, and a work corner needs number 5 people at most participated in, and 2 people at least, cooperation completes.Being in most cases that 2-3 people works, other people seldom participate in, or change rest.During whole tune type lane-change, carrying out according to a working line, the work corner that other can complete simultaneously does not intert wherein, and waste of human resource is relatively big, and tune type progress is slow.
5, cost increases: tune type lane-change process is the process not producing any value, otherwise, needing to consume substantial amounts of electric energy, wind energy, welding wire, solder flux and cost of labor etc. during tune type lane-change, the tune type time is the longest, and cost is the highest.
Therefore, assistant officer's the problems referred to above to be solved, a kind of method being badly in need of effective steel pipe's production unit tune type lane-change, in order to be conducive to improving the long term growth of domestic spiral steel pipe unit, it is also beneficial to reduce cost, carries out cost efficiency from every side movable.
Summary of the invention

Fig. 2, the example work flow block diagram of the present invention.
Detailed description of the invention
1-2 further illustrates the detailed description of the invention of the present invention below in conjunction with the accompanying drawings.
As a example by steel pipe specification Φ 1219 × 18 × 1550 tune type changes lane to steel pipe specification Φ 610 × 11 × 1400.
Seeing accompanying drawing 1-2, the step of concrete tune type lane-change is:
1, prepare before tune type:
(1) prepare instrument and the frock of tune type, prepare gas cutting equipment, overhead traveling crane, prepare No. 2 rollers of bearing roller, steel wire rope and pipe with small pipe diameter；
(2) critical path and secondary path are determined: determining a critical path and 2 secondary path in the tune type lane-change of the present invention operates, critical path needs overhead traveling crane to coordinate groundwork；
(3) parameter calculates: calculates steel pipe specification Φ 1219 × 18 × 1550 tune type and changes lane to the relevant parameter value of steel pipe specification Φ 610 × 11 × 1400, such as molding device parameter, propons and back axle parameter, hydraulic shear parameter, interior weldering parameter and outside weld parameter；
(4) Tiao Xing working group is set up: the operating point during arranging a people to be responsible for the work of tune type lane-change is coordinated and personal scheduling, critical path batch operation workman's number is 4 people, every secondary path batch operation workman number in principle is 2 people, can carry out the increase and decrease of personnel according to practical situation:
2, plate is moved back: exiting last root specification on production line is the steel pipe of Φ 1219 × 18 × 1550, and does not produces into the residue steel plate of steel pipe；
3, detaching equipment: critical path operator carry out dismantling the format roll in molding device, such as No. 1 roller, Large Diameter Pipeline No. 2 rollers and No. 3 rollers, dismantles the work such as guide plate, dismounting milling limit cutterhead；
4, equipment adjusts: while critical path operator's detaching equipment, staff in No. 1 secondary path need to carry out adjusting delivery machine, adjust prebending machine, turns dish, adjusts back axle and tune to fly the work such as weldering, wherein turn in the work of dish, the angle of rotating disk being adjusted by technological requirement toward little from big, the staff in No. 2 secondary path need to carry out adjusting edger roll, furnishing forming roll, adjusting guide plate and adjust the work such as molding device；
5, parameter adjustment: the staff in No. 2 secondary path is to No. 1 roller and each parameter value of No. 3 rollers, the parameter value of edger roll is adjusted, the parameter value that wherein No. 1 roller and No. 3 rollers need to adjust is the numerical value such as the corner of roller, inclination angle and absolute altitude, and the parameter of propons and the parameter of back axle, the parameter of hydraulic shear, interior weldering and outside weld is adjusted by the parameter value calculated by the 3rd step in step 1；
6, equipment is installed: critical path staff is under the cooperation of overhead traveling crane, carry out successively lifting No. 2 rollers of No. 3 rollers, No. 1 roller and pipe with small pipe diameter in molding device, lifting guide plate, dress milling limit cutterhead, turn down milling limit mouth, weldering and outer soldering equipment in lifting, after critical path staff installs molding device, molding device is adjusted by the staff of No. 2 secondary path；
7, trial production: trial production critical path staff carries out hanging volume, enters plate, pipe crimping head, the adjustment of related process standard, cut tune type pipe and cut the work of first complete steel pipe；
8, first steel pipe quality inspection: quality inspection work includes weld seam quality inspection, the detection of residual stress pipeline section and tube quality inspection, after the first tube quality produced is qualified, determine and produce the various parameters that unit adjusts, remove various aid and frock, clean tune type lane-change work place, then tune type lane-change end-of-job.
From small dimension Steel pipe shape adjusting, the operating procedure to big specification steel pipe is identical with above-mentioned steps, and different part or the parts simply changed are different.
The above is only the non-limiting embodiment of the present invention; substantial amounts of embodiment can also be derived; for the person of ordinary skill of the art; on the premise of without departing from the invention design and not making creative work; can also make the embodiment of some deformation and improvement, these broadly fall into protection scope of the present invention.
