Abstract

The utility model provides a coil cutting line. The coil cutting line comprises a roller frame (5), more than two upper and lower vertical overlapped roller groups, a cutting knife and conveyor belts, and is characterized in that a first speed reduction infrared detection probe (3) and a second lower knife infrared detection probe (4) are arranged between the left and the right conveyor belts (6) and (11) on the same plane. When the probe (3) detects the coming of a steel plate, information is fed back to a frequency conversion controller timely and then the steel plate can go forward at slow speed on rolling wheels. When the steel plate reaches the second infrared probe (4), the cutting knife is started immediately for falling the knife and lifting the knife, voltage and current are further restored for performing next-round operation, and a program is written into a PLC (programmable logic controller), so that the coil cutting line has the advantages of convenience in use and high precision. In addition, the upper and the lower roller groups are of the mixed structure of the vertical overlapped roller groups and the upper and the lower staggered roller groups, the utilization rate of rollers is increased, the number of the rollers is reduced, and the cost of a complete machine is further reduced.

Description

A kind of horizontal line of opening

Technical field

The utility model relates to the gentle cutting equipment of opening of steel coiled material, relate in particular to a kind of horizontal line of opening.

Background technology

Opening horizontal line, is with the stretching smoothing of the steel plate of rolling, and cuts into the abbreviation of different length and the neat industrial equipment that becomes to pile up neatly of sign indicating number according to product needed.Its production stage is uncoiling, smoothing, shearing, piling.Have Industrial Control Computer commander flying shear controller to accomplish shear precision, control production routine on the horizontal line large-scale opening, but cost is high, is not suitable for the common flat-bed machine of opening that medium-sized and small enterprises provide for oneself and installs.

In addition, traditional flat-bed machine platen roller of opening all is that vertically superposed up and down ground is installed in groups, in the smoothing process, one group of back only last relatively group to steel plate radian generation effect, form the waste of roller number, increased the complete machine manufacturing cost.

The utility model content

The technical problem that the utility model will solve provides a kind of horizontal line of opening; It has a low cost, the high-precision flat-bed machine cutting system of opening; Also have the roller group structure that each single roller can both the generation effect, thereby can not only improve out the operating efficiency of horizontal line, can also reduce its production cost.

The technical scheme that the utility model technical solution problem is adopted is: the roller group that comprise the roller frame, is arranged above and below more than two groups, cutting knife and conveyer belt are formed; In the middle of two conveyer belts first deceleration infrared detection probe being set about on the plane that coexists behind the said cutting knife pops one's head in second following cutter infrared detection; These two infrared probes connect frequency-variable controller and PLC chip, and the working procedure that described two probes and cutting knife cooperatively interact is written in the PLC chip.Its working procedure and operation principle thereof are: when first infrared probe elicites steel plate, in time give frequency-variable controller (Inverter) with feedback information; This frequency converter is controlled motor speed immediately and is made it speed and die-off, and lets said steel plate on said roller, advance slowly, because the time difference of motor reduction of speed; When steel plate is slow, arrive second infrared probe; Just the Len req of this steel plate setting starts cutting knife at once and descends cutter and cutter lifting rapidly, frequency converter recovery voltage and electric current in the process of cutter lifting; And so cycle operation forms an auto-programming, and these programs are all accomplished by the PLC Programmable Logic Controller.Because said Inverter and PLC and infrared probe all belong to matured product, so cost is very low.

In order more effectively to promote the smoothing effect of two rows Kun group interphase interaction, said two rows roller group for vertically superposed in twos roller group between the upper and lower with in twos about the roller group that staggers mix arrangement.The mechanicals efforts effect mainly shows between Kun that these stagger up and down each other and the Kun: when between the single roller that the steel plate that has radian has staggered through these; Promptly can receive the interaction between each adjacent up-down rollers; Form thereby resist the steel plate radian, play the smoothing effect.This roller group structure that is single roller that staggers has up and down increased the roller utilization rate, has reduced roller quantity, has reduced the complete machine cost.

First group of roller of the feeding mouth of said up and down two groups of rollers be vertically superposed roller group up and down, and strong drag force when two Kun make a concerted effort about can significantly improving is steadily advanced the steel plate of rolling.And roller group thereafter staggers arrangement architecture in order that save roller group sum about being between the upper and lower, reduces the complete machine manufacturing cost.

Below in conjunction with accompanying drawing and embodiment the utility model is described further:

The specific embodiment

As shown in Figure 1, that is arranging on roller frame 5 that two rows roller group forms opens the flat-bed machine agent structure.Shown in arrow, the steel plate 1 of rolling is smoothed in the middle of being clipped in two-layer roller, and volume is to the Luo Ban district that is made up of two conveyer belts 6 about in one plane and 11.When first infrared probe 3 in being arranged on two conveyer belt intermediate gap detects the steel plate that Kun group brings; At once signal is passed to frequency-variable controller (figure part omitted); According to the setting program that writes frequency-variable controller PLC chip; The voltage and current of this moment reduces, and motor (figure part omitted) slows down thereupon, and the steel plate pace is slowed down.When steel plate arrived second infrared probe 4, the PLC program started cutting knife (figure part omitted) at once and cuts off steel plate, and frequency converter recovers normal current, voltage during cutter lifting, formed the complete cyclic program of a cover.

As shown in Figure 2, the Kun group 10 about steel plate 1 quilt of rolling in the vertical rotation is drawn in, and sends in the smoothing Kun cohort.Roller 9 is smoothed with respect to 8 pairs of steel plates that still have radian of roller; In like manner, roller 8 is smoothed with respect to 7 pairs of these steel plates of roller, and roller 7 is smoothed with respect to 2 pairs of these steel plates of roller again; So form the straightener roll group structure of a mixing; The steel plate that will just launch still to have radian has step by step carried out effective smoothing, makes steel plate reach smooth with after the material standard, has promptly arrived the described cut-out operation of Fig. 1 embodiment.
