Abstract

The utility model relates to a flattening machine. Sectional bars are flat after process of the utility model, and the utility model has high work efficiency. The utility model comprises a motor, a speed reducer, topping rolls and bottom rolls. Both ends of the topping rolls are sheathed onto slide blocks respectively; the slide blocks are connected with connection screws respectively; exterior part of the connection screws are sheathed with worm gears respectively; the worm gears are sheathed onto a frame; the worm gears are engaged with worms, and the worms on both sides are connected by a clutch and a drive axle, and the worm on one side connected with the speed reducer by the clutch; the bottom rolls are installed on a base; the motor is connected with a gear box by the speed reducer and the clutch; distribution gears of the gear box are connected with the topping rolls and the bottom rolls by cardan joints. The utility model is characterized in that the topping rolls are in number of five roots; the bottom rolls are in number of six roots; the topping rolls and the bottom rolls are in alternate permutation.

Description

Level(l)ing machine

(1) technical field

The utility model relates to machining equipment, is specially level(l)ing machine.

(2) background technology

The structure of existing level(l)ing machine comprises motor, decelerator, topping roll, bottom roll, topping roll has 6, bottom roll to have 7, the two ends of described topping roll are set with in two side slides, described slide block connects screw mandrel respectively, the outside of described screw mandrel is respectively installed with worm gear, and described worm gear is installed on frame respectively, described worm gear respectively with worm engaging, the worm screw on both sides connects by shaft coupling, power transmission shaft, and the worm screw of a side connects reductor by shaft coupling; Bottom roll is installed on frame; Described motor connects gear-box by decelerator, shaft coupling, and the distribution gear of described gear-box connects topping roll, rolls rod down by universal joint respectively.When utilizing the level(l)ing machine fabircated shapes, motor via reducer drives the worm screw of both sides, worm screw is rotated by the worm gear drives screw mandrel, it is up that the screw mandrel that rotates drives slide block, thereby make topping roll, bottom roll separately, after section bar was installed, motor drove topping roll, nip roll rotation down by gear-box, universal joint, realizes the leveling to section bar.The shortcoming of this level(l)ing machine is exactly: the quantity of roll is more, owing to need the section bar of leveling thicker, section bar thickness is big, the extension of power is also bigger, and the quantity of roll is many, and is also more to the power that section bar applies, after the extension of a plurality of power and the stack, section bar is difficult on the contrary by leveling, and the operating efficiency of level(l)ing machine is lower.

(3) summary of the invention

At existing level(l)ing machine, the quantity of its roll is more, also more to the power that section bar applies, for thicker section bar, the extension of power is bigger, after the extension of a plurality of power and the stack, thick section bar is difficult on the contrary by leveling, the shortcoming that the operating efficiency of level(l)ing machine is lower, and the utility model provides another level(l)ing machine, section bar after the processing is more smooth, and the operating efficiency of level(l)ing machine is higher.

Its technical scheme is such: it comprises motor, reductor, topping roll, bottom roll, the two ends of described topping roll are set with in slide block, described slide block connects screw mandrel respectively, the outside of described screw mandrel is respectively installed with worm gear, described worm gear is installed on frame respectively, described worm gear respectively with worm engaging, the worm screw on both sides connects by shaft coupling, power transmission shaft, the worm screw of a side connects reductor by shaft coupling; Bottom roll is installed on the base of frame; Described motor via reducer, shaft coupling connect gear-box, the distribution gear of described gear-box connects topping roll, rolls rod down by universal joint respectively, it is characterized in that: totally 5 of described topping rolls, totally 6 of described bottom rolls, upper pressing rod, bottom roll are staggered and arrange.

The utility model adopts after the said structure, because the quantity of roll reduces, accordingly the quantity to the section bar applied force of processing is also few, the extension of power and stack are also few, and section bar is easily smooth, and the operating efficiency of level(l)ing machine is higher, thereby avoided existing level(l)ing machine, the quantity of its roll is many, and section bar is difficult for smooth, the shortcoming that the operating efficiency of level(l)ing machine is lower.

(4) description of drawings

Signal and partial sectional view that Fig. 1 looks for master of the present utility model.

Fig. 2 is the structural relation figure of topping roll and bottom roll.

(5) specific embodiment

See Fig. 1, Fig. 2, the utility model comprises motor, reductor 3, not 5 (not expressing motor among Fig. 1), topping roll 15, bottom roll 16, the two ends of topping roll 15 are set with in slide block 14, the slide block 14 of both sides connects screw mandrel 7 respectively, 11, screw mandrel 7,11 outside is respectively installed with worm gear 8 (among Fig. 1, the worm gear 8 on right side does not give expression to, express the structure of worm screw 12 emphatically), worm gear 8 is installed on frame 6 respectively, worm gear 8 meshes with worm screw 12 respectively, the worm screw 12 on both sides is respectively by shaft coupling 10, power transmission shaft 9 connects, and the worm screw 12 of a side (being the left side among the figure) connects reductor 5 by shaft coupling; Bottom roll 16 is installed on the base 18 of frame; Motor via reducer 1, universal joint 2 connects gear-boxes 3, and the distribution gear of gear-box 3 connects topping rolls 15, rolls rod 16 down by universal joint 4 respectively, sees Fig. 2, totally 5 of topping rolls, totally 6 of bottom rolls, on roll rod 15, bottom roll 16 is staggered and arranges.13,17 be respectively support roller, lower support wheel, prevent topping roll 15, bottom roll 16 stress deformations.

Claims

1, level(l)ing machine, it comprises motor, reductor, topping roll, bottom roll, the two ends of described topping roll are set with in slide block, described slide block connects screw mandrel respectively, the outside of described screw mandrel is respectively installed with worm gear, and described worm gear is installed on frame respectively, described worm gear respectively with worm engaging, the worm screw on both sides connects by shaft coupling, power transmission shaft, and the worm screw of a side connects reductor by shaft coupling; Bottom roll is installed on the base of frame; Described motor via reducer, shaft coupling connect gear-box, the distribution gear of described gear-box connects topping roll, rolls rod down by universal joint respectively, it is characterized in that: totally 5 of described topping rolls, totally 6 of described bottom rolls, upper pressing rod, bottom roll are staggered and arrange.
