Abstract
The utility model discloses a hot sawing machine feeding device, which comprises a lower sliding seat and an upper sliding table, wherein the lower sliding seat is provided with a rotatable lower riding wheel group, the upper sliding table is placed on the lower riding wheel group, a compaction mechanism is arranged in the upper sliding table, the compaction mechanism comprises a press roll shaft, a pull rod and upper press rolls, and the upper press rolls are respectively arranged on the two ends of the press roll shaft. The pull rod vertically runs through the press roll shaft, a bottom plate of the upper sliding table and a top plate of the lower sliding seat, and the two ends of the pull rod are respectively sleeved with butterfly spring washers and are screwed in locking nuts. The hot sawing machine feeding device uses the butterfly spring washers as anti-loosing washers, along with the abrasion between the roll surfaces of the upper press rolls and the plate surface of an upper sliding plate, once the locking nuts loose, an upper locking nut and the press roll shaft and a lower locking nut and the lower siding seat are compressed by excellent self elasticity of the butterfly spring washers depending on self elasticity, thereby being capable of effectively preventing the locking nuts from loosing, reducing the maintenance time, reducing the maintenance time, effectively guaranteeing production to be smooth, and increasing the production efficiency.
Description
Technical field
The utility model relates to a kind of medium-sized hot-metal sawing machine, relates in particular to a kind of feed arrangement of hot-metal sawing machine.
Background technology
The slide-like hot-metal sawing machine is the visual plant of medium-sized production line subsequent process, and it is being born the steel behind the roll forming are carried out sawing work.Hot-metal sawing machine mainly divides three bigger devices: the Traverse Displacement Unit of saw blade transmission device, saw blade feeder and adjustment scale.
The feed motion of hot-metal sawing machine is realized by motor, reductor and rack-and-pinion transmission.Rotating subiculum wheels are set on the lower slider, and the last slide unit (sending parts to) of hot-metal sawing machine holds up by the subiculum wheels, and last slide unit can move back and forth along lower support wheel, realizes that the saw that advances of hot-metal sawing machine is operated.The weight of slide unit in the too much increase, pressure roller on four pairs is housed in last slide unit, be contained in respectively on four pressure roller shaft, the pull bar tension of the every pair of pressure roller shaft top board by vertically passing pressure roller shaft, the base plate of going up slide unit and lower slider, the lower end of pull bar is fixed in the corresponding hole of lower slider with nut, last pressure roller is pressed in the slide unit inboard by upper slide, and by the feed motion of energy hot-metal sawing machine in fact of rolling back and forth between last pressure roller and the upper slide.
When hot-metal sawing machine was done feed motion, pressure roller was subjected to power vertically upward, the gravity that outwards moves with the center of gravity that produces during the slide unit feeding on the balance hot-metal sawing machine.During motion, last pressure roller and upper slide produce relative friction forces, and when considering its work simultaneously, the saw steel will produce huge vibration, and last pressure roller also vibrates together with last slide unit, and last pressure roller will be subjected to simultaneously from radial and axial pressure.Dispute sections sheet packing ring loosens till the locking mode that this device is taked, after using a period of time, because of the wearing and tearing between last pressure roller and the upper slide, the power of all directions that last pressure roller vibration is suffered, make to go up to produce big gap between pressure roller and the upper slide, be difficult for fastening its jam nut at ordinary times.The gap is big more, and last pressure roller string when work is moving big more, and the wearing and tearing of last pressure roller and upper slide are also fast more, cause hot-metal sawing machine feed motion jam, even can not carry out feed motion.Bearing in the last pressure roller of hold-down mechanism is a ball bearing, and ball bearing can bear certain radial load, can bear axial load again.But the situation that often occurs the bearing ball wearing and tearing in using, analyzing and finding to go up what mainly be subjected in the pressure roller is bigger radial load and a small amount of axial load, causes the damage of pressure roller inner bearing also serious.It is serious that said structure all causes part of appliance to change, and maintenance time is long, seriously influenced carrying out smoothly of producing.
The utility model content
At the prior art above shortcomings, the utility model provides a kind of prolongation spare part service life, reduces maintenance frequency, the hot-metal sawing machine feed arrangement that reduces maintenance cost and enhance productivity.
The hot-metal sawing machine feed arrangement that the utility model provides comprises lower slider and last slide unit; Rotating subiculum wheels are set on the described lower slider, and last slide unit is positioned on the subiculum wheels; Described going up in the slide unit is provided with hold-down mechanism, and hold-down mechanism comprises pressure roller shaft, pull bar, is separately positioned on the last pressure roller at pressure roller shaft two ends; Described pull bar vertically passes pressure roller shaft, the base plate of going up slide unit and the top board of lower slider, and two ends screw in locking nut; The two ends of described pull bar are set with the butterfly spring packing ring, and the described pull bar locking nut at two ends up and down is pressed on the top board of pressure roller shaft and lower slider by the butterfly spring packing ring respectively.
Further, the two ends of described pressure roller shaft are set with cylinder roller bearing, and described upward pressure roller is installed on the end of pressure roller shaft by cylinder roller bearing.
Compared with prior art, the utlity model has following advantage:
1, the utility model adopts and is set with the butterfly spring packing ring at the two ends of pull bar, the locking nut at two ends is pressed on the top board of pressure roller shaft and lower slider by the butterfly spring packing ring respectively, wearing and tearing along with the roll surface and the upper slide plate face of last pressure roller, locking nut is in case occur loosening, the butterfly spring packing ring has better elastic because of self, rely on the elastic force of self to compress between upper locking nut and pressure roller shaft and lower locking nut and the lower slider, can prevent effectively that locking nut is loosening, reduce maintenance frequency, reduce maintenance cost.
2, the two ends of pressure roller shaft are set with cylinder roller bearing, last pressure roller is installed on the end of pressure roller shaft by cylinder roller bearing, cylinder roller bearing has improved the bearing capacity of the radial load of its bearing, prolonged service life, reduce the bearing replacing number of times, save the spare parts consumption cost, reduce maintenance time, guaranteed effectively to produce and carried out smoothly, enhanced productivity.
