Abstract
The utility model relates to a tapping position signal acquisition and automatic controlling device of a movable workpiece of a roller hearth heating furnace. In existing production, one person is arranged to wait at a discharge opening to see the workpiece entering into a discharge section, and then rings a bell to direct a rolling mill operator to start a discharge roller, thereby wasting labor. The device provided by the utility model comprises a heating furnace which is divided into three metal rollers which are fixed by a graphite bearing pedestal. The device is characterized in that the three rollers comprise a feeding roller, a conveying roller and a discharging roller; two adjacent rollers in the discharging roller are taken as tapping position points and are defined as rollers A and B, a lead A and a lead B are drawn out from the rollers A and B respectively and are connected with a work power supply, and the work power supply is further connected with a relay, an indicating lamp and a PLC (Programmable Logic Controller) control module through the leads. According to the device provided by the utility model, the cost for one person is saved, the possibility of pulling back a furnace plate due to loss of steel temperatures is reduced, and the rolling rhythm is improved.
Description
Technical field
The utility model relates to a kind of roller hearth type heating furnace Moving Workpieces steel-supplying position signals collecting and automatic control device.
Background technology
Roller hearth type heating furnace is as the major equipment of the hot rolling blank heating of metallurgical processing industry, three sections of motors of general employing drive, in heat-processed, three sections of roller-ways are synchronous, when workpiece runs to tap hole position, in order to reduce the loss of steel temperature, improve rolling rhythm, need discharging motor to start rapidly quickly discharging, therefore, very important for the location of workpiece in high-temperature burner hearth.
Original design employing infrared sensor, setting position is at furnace outlet section inverse four, on five roller-ways, but in practical application, infrared sensor is under burner hearth 800 degree high temperature, None-identified, making side utilizes simulation to control, at feeding port (cold-zone), install an infrared sensor additional, as position starting point, by calculating roller line speed, simulate workpiece physical location, in actual applications, reason due to three sections of roller-way synchronisms and driving chain dead band, after having moved 20 meters, error is larger, not that workpiece is not gone to discharging section and just posted a letter, be exactly that workpiece has been come out of the stove and just posted a letter, cause the loss of steel temperature can not rolling, producer has been brought to very big difficulty, need to arrange personnel to wait at discharge port, seeing that workpiece enters discharging section, the commander mill personnel that rings a bell again starts discharging roller-way, waste of manpower, also easily make mistakes.
Utility model content
The utility model is for above-mentioned defect, a kind of roller hearth type heating furnace Moving Workpieces steel-supplying position signals collecting and automatic control device are provided, can accurately gather steel-supplying position signal level of automation, the labour intensity that has reduced cost of labor and rolling operator, has improved production efficiency and quality product.
For this reason, the utility model is taked following technical scheme, roller hearth type heating furnace Moving Workpieces steel-supplying position signals collecting and automatic control device, comprise process furnace, in process furnace, be divided into three sections of roller-ways, roller-way is metal roller-way, adopt graphite shaft bearing to fix, it is characterized in that three sections of described roller-ways are respectively feeding roller table, rollgang and discharging roller-way, in described discharging roller-way, two adjacent roller-ways are as steel-supplying position point, be defined as respectively A roller-way and B roller-way, on described A roller-way and B roller-way, draw respectively wire A and wire B, described wire A is connected working power with wire B, described working power connects rly. by wire again, pilot lamp and PLC control module.
Described roller hearth type heating furnace Moving Workpieces steel-supplying position signals collecting and automatic control device, is characterized in that the bearing support of described wire A from roller-way A welds screw and draw, and the bearing support welding screw of described wire B from roller-way B drawn.
Described roller hearth type heating furnace Moving Workpieces steel-supplying position signals collecting and automatic control device, is characterized in that the bottom insulcrete liner of described graphite shaft bearing.
Described roller hearth type heating furnace Moving Workpieces steel-supplying position signals collecting and automatic control device, is characterized in that being nested with spring pad and insulation thimble on the bolt for fixing graphite bearing support.
The utility model is accurate for tapping signals collecting, make mill personnel obtain tapping after signal, only need push-switch, Work piece high-speed tapping, obtains the little steel platform that turns and automatically drops to 10 meters of quick roller-ways, and roller-way self-feeding is to hot rolls feeding roller table fast, whole-process automatic control, save a cost per passenger trip, reduced because the loss of steel temperature retracts stove plate, improved rolling rhythm.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
Fig. 2 is electrical block diagram of the present utility model.
Embodiment
Below in conjunction with specific embodiment, further set forth the utility model.
Roller hearth type heating furnace Moving Workpieces steel-supplying position signals collecting and automatic control device as depicted in figs. 1 and 2, comprise process furnace, is divided into three sections of roller-ways in process furnace, and roller-way is metal roller-way, adopts graphite shaft bearing to fix.Three sections of roller-ways are respectively feeding roller table, rollgang and discharging roller-way, in discharging roller-way, two adjacent roller-ways are as steel-supplying position point, be defined as respectively A roller-way 2 and B roller-way 3, on A roller-way 2 and B roller-way 3, draw respectively A wire 5 and B wire 4, A wire 5 is connected working power 12 with B wire 4, and working power 12 connects rly. 9, pilot lamp 11 and PLC control module 10 by wire again.The bearing support welding screw of A wire 5 from A roller-way 2 drawn, and the bearing support welding screw of B wire 4 from B roller-way 3 drawn.Insulcrete liner 8 for the bottom of graphite shaft bearing.On bolt 6 for fixing graphite bearing support, be nested with spring pad 7 and insulation thimble.
From roller-way, contact with workpiece 1 and start power taking signal, select discharging section A, bis-roller-ways of B, carry out the insulation of driving chain wheel and bearing support, adopt independent DC24V as controlling power supply, recycling PLC technology is integrated into signal in Controlling System, has reached whole-course automation.Principle of work is: when workpiece arrives on A, B roller-way, A, 2 short circuits of B form loop, and relay K is closed, and tapping pilot lamp is bright, and synchronous signal is sent into PLC, carries out time variable control.Due to first, for some contact there will be jitter phenomenon, we get positive rise pulse, as PLC signal, take push-switch as power-off signal, calculate a secondary program, have reached design requirements.
Should be understood that these embodiment are only not used in restriction scope of the present utility model for the utility model is described.In addition should be understood that those skilled in the art can make various changes or modifications the utility model after having read the content of the utility model instruction, these equivalent form of values fall within the application's appended claims limited range equally.
