Description
Technical field
The utility model relates to copper strips processing technology, is specially a kind of copper strips rewinding unit.
Background technology
Clock hood type furnace annealing way is extensively adopted by copper coin band enterprise because having the advantages such as equipment cost is low, efficient, energy-conservation, but the problem of (copper strips) annealing process adhesion that simultaneously has band.Along with market improves constantly the requirement of the surface quality of copper material product and dimensional accuracy, annealing operation product surface quality requires also improving constantly, and 0.1～0.3mm strip product frequent bonding because of band in annealing operation causes product rejection in batch.Analyze to find that band occurs that in annealing operation the main cause of bonding is band overtension and causing in the operation of rolling, if can effectively reduce the tension force of band, just can solve the adhesion problem of band in annealing process.
The uncoiling of copper strips is undertaken by uncoiler, and rolling is completed by special-purpose coiling machine.Uncoiler comprises direct current generator, gear reduction box, hydraulic collapsible reel, deflection roll and hydraulic pressure ground pit type feeding cart, and the front and back operation of dolly adopts hydraulic motor, and operation adopts hydraulic jack up and down; Coiling machine comprises direct current generator, gear reduction box, hydraulic collapsible reel, the push pedal of the hydraulic pressure roll coil of strip, pressure roller etc.
Summary of the invention
The technical problem that the utility model is the bonding that solves current copper strip and cause because of overtension in when annealing, provides a kind of copper strips rewinding unit.
The utility model is to adopt following technical scheme to realize: a kind of copper strips rewinding unit, comprises spaced uncoiler and coiling machine; Uncoiler and coiling machine all drive by the interior direct current generator of establishing; Between uncoiler and coiling machine, be also provided with device for measuring force; Described device for measuring force comprises a base, on base, by uncoiler, to coiling machine direction, is provided with in turn the first guide roller, the second guide roller, jockey pulley, the 3rd guide roller and the 4th guide roller; Described jockey pulley and each guide roller are all arranged on base by pair of bearing; The bearing block bottom at described jockey pulley place is provided with pressure sensor; The first, the 4th guide roller roll surface top is positioned at same level; Described second, third guide roller is positioned at same level and is symmetricly set on the both sides of jockey pulley; The roll surface top of described the first guide roller and the roll surface bottom of the second guide roller are positioned at same level; The roll surface top of jockey pulley is higher than the roll surface bottom of second, third guide roller; The signal output part of described pressure sensor is connected with a PLC; The signal output part of pressure sensor is connected with the signal input part of PLC; The signal output part of PLC is connected with the direct current generator dynamic Control end of uncoiler and coiling machine.
Jockey pulley by the frictional force between roll surface and band to band generation effect.Because frictional force is directly proportional to normal pressure, only the band on roller is tightened up, and while applying normal pressure to roller surfaces, could produce frictional force, could increase or reduce the tension force of steel band.The pressure that the pressure sensor of jockey pulley bottom records as shown in Figure 5 and the tension force schematic diagram of band, tension value just equal with joint efforts the spindle central that force value ，Zhou center refers to jockey pulley.During use, copper strips is placed on to uncoiling on uncoiler, copper strips after uncoiling is directed to the first guide roller of device for measuring force, through the upper roll surface of the first guide roller, the lower roll surface of the second guide roller arrives jockey pulley, after the upper roll surface of jockey pulley is by the lower roll surface of the 3rd guide roller and the upper roll surface of the 4th guide roller by coiling machine rolling.The upper roll surface of the first guide roller and the 4th guide roller is lower than the roll surface top of second, third guide roller, and band (after copper strips uncoiling) can be tauted like this, and the pressure sensor of jockey pulley place bearing block below can accurately measure the tension force of band; Pressure sensor is transferred to PLC after measuring the tension force of band and converting corresponding tension signal to the signal of telecommunication, the CPU establishing in PLC direct current generator dynamic Control end to uncoiler and coiling machine under the support of corresponding software is exported corresponding signal, regulate the rotating speed of uncoiler and coiling machine, and then the Tensity size of band on adjustment of tonicity roller, the suffered tension force of band is remained in the scope of setting.The speed of band rolling is faster, and tension force is just larger, and the speed of rolling is slower, and tension force is just less.If the excessive PLC of strap tension just adjusts the rotating speed that reduces uncoiler and coiling machine; If the too small PLC of tension force just adjusts the rotating speed that increases uncoiler and coiling machine, with this, adjust the size of strap tension; Strap tension reaches a rational scope, just there will not be the situation of adhesion during annealing.Described corresponding software is that those skilled in the art are easy to write.
The utility model can be real-time by arranging of a device for measuring force the tension force of mensuration band, and the uncoiling rolling speed of realizing uncoiler and coiling machine by a PLC, controls the Tensity size of band with this.The tension force of band can be adjusted in rational scope, just can avoid the phenomenon of adhesion during annealing.The utility model is simple in structure, easy and simple to handle, applied widely.
