A signal transmitting device of the utility model fetches pulse signals from a tension straightening machine; the length of a blank is changed by a universal conversion switch; a programmable controller counts the pulses and outputs the size-defining signals after correcting casting blank speed and slip, and the other output of the programmable controller which controls an indicating light can be used for size-time cutting. The utility model has the advantages of simple structure, low cost, high precision, and convenient operation. The utility model can be installed and used on the spot to verify the effects without stopping production.
Description
The utility model relates to continuous casting billet automatic gauging device.
Continuous casting billet is normally realized by following process: molten steel is aligned through the straightening machine through crystallizer and secondary cooling zone territory cooled and solidified again, and size cuts into base in accordance with regulations then.Produce steel billet in batches with continuous casting process, every batch of its length of steel billet generally all has certain requirement, and error is the smaller the better naturally.This is because too short, no doubt will scrap, and longly also can cause cutting off again and causes the waste of material.For producing qualified products, people once adopted many measures, existing having of using: manual scale method, and promptly the operative employee estimates the length of steel billet as requested, and Push switch is implemented cutting; The unavoidable error of manual operations is big, and waste is many, and particularly night shift more very; Thus, automatic gauging arises at the historic moment, and mainly contains following several: one, and be touch type automatic gauging device: hang copper ball or the copper roller is installed in line scale position, when continuous casting billet was in contact with it, the cutting machine switch promptly was switched on, and cutting machine is promptly implemented cutting to steel billet; Another kind is to adopt to be compressed the baffle plate that air blows afloat and to replace copper ball (copper roller), when air-flow was blocked in strand arrival, baffle plate was sagging, makes the cutting machine switch connection, and implement to cut, the weak point of these methods is copper balls, can damage the copper roller because of touching, Chang Yinyu " " defective insulation and leaking electricity, and whenever strand nose delay contact copper roller, and spent the time of cutting, caused product size excessive; Baffle plate because of bleed pressure, and goes wrong easily.These touch type length measuring devices, though cost is low, maintenance workload is big, precision is also poor, changes the scale trouble, and is special when a Ban Shinei will produce the product of several specifications, needs mobile copper ball for several times.Two, adopt detectors such as photoelectricity, infrared, laser, form contactless automatic gauging device, adopt infrared emission electronics device and infrared reception electronics device as Chinese patent ZL95207328.5 disclosed " the once automatic location of cutting, length measuring device ", be fixed on the two rhizoid thick stick sliding bars, devices such as electrical actuators also are housed, and device is complicated, the cost height; In addition, also have metering system that uses the band hydraulic cylinder and the automatic gauging device that uses the industrial television technology.The said apparatus installation that all need stop production.
The purpose of this utility model is to provide that a kind of cost is low, precision is high, conveniently use, safeguard laborsaving, needn't stop production, and the continuous casting billet length measuring device that confirms effect on probation can be installed then and there.
The utility model is to realize like this, continuous casting billet automatic gauging device, comprise signal generating device, industrial control unit (ICU), the scale selector switch, signal generating device is made up of inductor and sensor, inductor is blade-carrying becket, be sleeved on the relevant beaming roller of straightening machine, rotate synchronously with the straightening machine, sensor is positioned at by the beaming roller, is subjected to the blade induction on the inductor to send pulse signal, the scale selector switch adopts universal seclector, operating switch just can change and cuts another kind of length semifinished product, and industrial control unit (ICU) adopts Programmable Logic Controller, according to selecting length signals paired pulses signal counting, and according to after the correction of working condition work numeral, output scale signal is transferred to cutting machine cutting, another road output of controller, and the control indicator lamp is realized the multiple length cutting.
Said universal seclector has several conversion retainings, and each conversion shelves mark is being write base long number word, said straightening machine reference axis, can be the straightening machine become case fast, middling speed or slow axis, also can be the axle of motor.
The utility model has the advantages that: owing to adopt technical measures such as information sensing, programmable control and universal seclector, not only simple in structure, with low cost, and the sizing accuracy height, easy to use, installation need not stop production.
The following drawings and embodiment will be described further technical characterictic of the present utility model

Embodiment: as shown in Figure 1, the technical process of continuous casting billet production is: the molten steel cooling forms shell in the crystallizer 1, and through secondary cooling zone territory 2, molten steel solidifies gradually in the shell, and is stretching through the beaming roller rotation of straightening machine 3.Inductor 4 is sleeved on the relevant beaming roller on the straightening machine, do to rotate synchronously with straightening machine 3, be placed on inductor 4 other sensors 5 and send pulse signal, send into programmable controller PlC6 counting, make speed, the correction of skidding, PLC6 starts cutting machines 8 to cutting machine 8 output cutoff signals and cuts.Need to change semifinished product length, pull universal seclector 7.
Shown in Fig. 2 A, the utility model, straightening machine 3 is made up of motor 10, gearbox 11, gear-box 12, straightening roller (three pairs) 13, and their beaming roller is the relevant beaming roller of straightening machine.On the beaming roller in gearbox 9 suit the inductor 4 of band blade metal ring, next door sensor installation 5, the beaming roller of gearbox 9 rotates synchronously with the relevant beaming roller of straightening machine, inductor 4 rotates, its blade is responded to sensor 5, sends pulse signal.
Shown in Fig. 2 B, the output of another road of controller, the control indicator lamp: flicker, expression are normal, long bright, and the prompting scale will arrive, dark, represent that scale arrives.If owing to the production equipment reason can not be cut, can implement the cutting of two multiple lengths, triple scale or the like multiple length.
