Description
Technical field
The invention belongs to band steel finishing process field, relate to a kind of paper-thin strip high speed Precise asymptotics positive substandard products sorting coiling technique.
Background technology
Band steel after cold mill complex rolling, has to pass through finishing processing, just can obtain high-quality qualified products.Precise asymptotics mainly carries out rewinding, deburring, surface inspection, painting wet goods operation.Because finishing process is last procedure of finished strip, must not produce new defect, the inaccurate generation of belt steel surface wipes scuffing and plastic deformation.
Modernization tandem mills is constantly to high speed, automation direction development, and the speed of service is more and more higher.In order to mate output, the desin speed of Precise asymptotics is also more and more higher.But, because the supplied materials volume of Precise asymptotics is often off quality at head, afterbody or middle a certain section strip steel, need to reject.
Existing Precise asymptotics comprises the equipment such as uncoiler, beginning machine, calibrator, pin hole instrument, crop shears, waste trolley, pinch roll, welding machine, rear slewing rollers, coiling machine.But at present, common way, after finding band steel off quality, first being cut with cutting to cut, then unloading qualified coil of strip from coiling machine; Start again to batch defective band steel, after completing, unload defective coil of strip from coiling machine, then start to batch qualified band steel, constantly repeat this process, until complete the process of whole supplied materials coil of strip.Whole production process is loaded down with trivial details, and efficiency is lower, cannot mate preceding working procedure output well.
Summary of the invention
The object of the invention is to solve existing finishing production process loaded down with trivial details, efficiency is lower, cannot mate the problem of preceding working procedure output well.
For this reason, the invention provides a kind of paper-thin strip high speed Precise asymptotics positive substandard products sorting coiling technique, comprise the following steps:
Step one: rolling steel coil on reel of uncoiler, coil of strip from the outset machine to welding machine self-threading tape;
Step 2: judge that steel band takes the lead whether certified products, if certified products, forward step 3 to; If substandard products, forward step 4 to;
Step 3: be positioned at the reverse threading of certified products steel end at certified products pinch roll place to welding machine, and the certified products band steel taping head welding of coil of strip, after completing, certified products band steel is batched in interlock, forwards step 7 to;
Step 4: judge whether substandard products band steel taping head has batched, if completed, forwards step 5 to; If do not completed, forward step 6 to;
Step 5: positive substandard products band steel cut by crop shears, substandard products band steel whipping, to substandard products pinch roll, waits to be welded; Certified products band steel taping head automatic reverse threading, to welding machine, forwards step 3 to;
Step 6: judge whether substandard products coiling machine has coil of strip, if there is coil of strip, is positioned at the reverse threading of substandard products steel end of substandard products pinch roll to welding machine, and the welding of coil of strip substandard products band steel, and substandard products band steel is batched in interlock; If do not have coil of strip, substandard products band steel taping head threading is to substandard products coiling machine, and substandard products band steel is batched in interlock;
Step 7: judge steel end whether certified products, if certified products, automatic whipping, to certified products pinch roll, forwards step one to and carries out next volume and produce; If not certified products, positive substandard products band steel cut by crop shears, and the automatic whipping of certified products band steel is to certified products pinch roll, and substandard products band steel automatic reverse threading, to welding machine, forwards step 8 to;
Step 8: judge whether substandard products magnetic tape trailer has batched, if completed, the automatic whipping of substandard products band steel, to welding machine, forwards step one to and carries out next volume production; If do not completed, forward step 6 to.
The data collected by calibrator, pin hole instrument with the judgement of steel taping head, the positive substandard products of magnetic tape trailer are judged.
The reverse threading of certified products steel end described in step 3 is to welding machine, and by controlling certified products pinch roll driving motor and loop back roll driving cylinder, realization is positioned at the reverse threading of certified products band steel of certified products pinch roll to welding machine.
In step 4, whether substandard products band steel taping head has batched, and the data collected by calibrator, pin hole instrument are judged, when judging band steel as certified products, certified products band steel reaches crop shears, then substandard products take the lead to have batched.
The reverse threading of substandard products steel end in step 6, to welding machine, is rotated backward by substandard products pinch roll driving motor and substandard products Coiler driving device motor simultaneously and realizes.
In the process of step 7, during process substandard products magnetic tape trailer, according to substandard products magnetic tape trailer length, can artificial selection crop shears whether be adopted to carry out cutting to length.
The present invention proposes paper-thin strip high speed Precise asymptotics positive substandard products sorting coiling technique, make high speed Precise asymptotics can realize the sorting of positive substandard products band steel smoothly and batch function, enhance productivity, mate front road production process output better, be applied to band steel finishing process, successful.
