Abstract
The utility model relates to a hot composite machine for composite steel plates, which comprises a pair of pressure rollers arranged on a machine frame, and a holding-down device for the rollers, wherein, the holding-down device is composed of a cycloidal pin wheel reducer driven by an electric machine and a holding-down screw driven by the reducer. The holding-down screw is connected with a bearing seat of a holding-down roller. Electric heating devices are arranged at the periphery of the pressure rollers, wherein, a heating device of a lower roller is divided into a left and a right parts between which a clearance channel communicated with the lower roller is arranged for discharging impurities. The electric heating devices can be used for heating the rollers. The utility model has the advantages that the temperature is uniform and is convenient to control.
Description
The utility model relates to a kind of two roll squeezers, particularly a kind of thermal composite machine that is used for clad steel plate.
Clad steel plate, band are that two-ply, the band that will be coated with the vibration damping layer form by roll extrusion under certain pressure and temperature.Present steel plate heat is compound all to be to carry out on general two-roller mill, and its equipment is huge, complex structure, and be not equipped with special-purpose heater.For satisfying technological requirement, adopt roll to roll preceding preheating usually, as allowing the hot rolling part earlier,, perhaps carry out part or all preheatings with coal gas, wet goods breaker roll with the roll preheating repeatedly by roll.The effect of these methods is all relatively poor, non-uniform temperature not only, and the temperature difference is bigger, and operation is also inconvenient.In addition, the screw screwdown gear of existing two-roller mill adopts two-stage worm speed-down or roller gear and worm screw double reduction, and its efficient is lower, and manufacturing cost is higher, adjusts also inconvenient.
Task of the present utility model provides a kind of thermal composite machine that is exclusively used in clad steel plate.
Task of the present utility model is to finish by following approach: the thermal composite machine of the clad steel plate that is provided comprises a pair of screwdown gear that is contained in pressure roller on the frame and this roller, this screwdown gear is formed by motor-driven reducing gear with by the housing screw that this reducing gear drives, this housing screw links with the bearing block of depressing roller again, the reducing gear that it is characterized in that said screwdown gear adopts the cycloidal-pin wheel decelerator, and the periphery of said pressure roller is provided with electric heater unit.Wherein play the heater of roller to be divided into left and right sides two parts, a clearance channel that communicates with following roller is arranged between these left and right sides two parts.
Because the hot combined temp of steel plate is lower, thus adopt peripheral electrical heating not only can satisfy the heat request that adds of roller, and be convenient to carry out temperature control.Because composite force required during clad steel plate is less, so that screwdown gear adopts the cycloidal-pin wheel decelerator not only can make is simple in structure, compact, and is convenient to processing, manufacturing cost is also lower.
Heating in the above-mentioned electric heater unit can adopt electrothermal tube, like this can be more safer.
Compared with prior art, of the present utility model simple in structure, compact, heating-up temperature evenly and be convenient to control is manipulated also more conveniently, is specially adapted to production line large-scale, high-speed automated complex plate strip.
Below in conjunction with accompanying drawing content of the present utility model is illustrated.
Fig. 1 is the structure chart of the utility model roller heater.
Fig. 2 is the expanded view of heating element heater among Fig. 1.
Fig. 3 is the structural representation of the utility model roller screwdown gear running part.
Fig. 4 is the structural representation of the utility model screwdown gear pressure part.
As shown in Figure 1 and Figure 2: upper roller 1 is hollow roll with following roller 2, and the preheating of hollow roll is rapid, and control accuracy of temperature is higher.Electric heater unit 3 has coated the area of roller 3/4ths, and about last heater 31 and following heater 32 are divided into two ones, wherein descending between left and right sides two parts of heater 32 has a clearance channel 33, so that the eliminating foreign material.The outermost of heater 3 is heat-insulation layers 34, and the inboard is an electrothermal tube 35.Electrothermal tube 35 laterally is being seen as circular arc, vertically is seen as snakelike coiling (as shown in Figure 2) along roller.Electric heater unit 3 vertically is divided into three thermal treatment zone A, B, C again along roller, and each thermal treatment zone is equipped with the thermistor 36 that the control temperature is used, and each thermal treatment zone can be controlled separately.The temperature control of the thermal treatment zone adopts existing general control device to meet the demands.
During production, the blank 11 through heating just is combined into complex plate strip 12 by the roll extrusion of heated upper and lower roller 1,2 and heating again.
As shown in Figure 3, Figure 4: the screwdown gear of roller adopts the screw screw-down structure, form by cycloidal-pin wheel decelerator 5, worm screw 6, worm gear 7 and housing screw 8 that motor 4 drives, wherein worm screw 6 links with the output shaft of decelerator 5, housing screw 8 connects for feather key with worm gear 7, pressure sensor 9 is equipped with in its lower end, and links to each other with the plain bearing housing of upper roller 1.Starter motor 4 can drive housing screw 8 upper and lower moving through cycloidal-pin wheel decelerator 5 and worm and gear, and the plain bearing housing that drives upper roller 1 then moves along the slide rail of frame 10, is used to adjust pressure.This compounding machine is provided with two cover screwdown gears, is used in respectively on the bearing block at roller two ends.
