Abstract

The utility model relates to cold rolled section steel rolling equipment which comprises a rack, an upper plain-barreled roll and a lower plain-barreled roll. The cold rolled section steel rolling equipment is characterized in that two synchronous reducers are respectively arranged at the two sides of the rack and driven by an identical motor, output gears of the reducers are respectively meshed with lower plain-barreled roll gears at the two ends of the lower plain-barreled roll, and the lower plain-barreled roll gears at the two ends of the lower plain-barreled roll are also respectively meshed with upper plain-barreled roll gears at the two ends of the upper plain-barreled roll. Due to the fact that the two reducers are respectively arranged at the two sides of the rack and both driven by the identical motor, the same rotating speed of the two ends of each roll shaft is ensured, the cold rolled section steel rolling equipment can be used for manufacturing a product with the width of more than two meters, and the whole structure and the manufacture cost are greatly reduced.

Description

A kind of cold-rolled forming section rolling equipment

Technical field

The utility model relates to a kind of rolling equipment, relates in particular to a kind of cold-rolled forming section rolling equipment.

Background technology

In the prior art, cold-rolled forming section is rolled uses cold-rolled forming section rolling equipment machine in the process, he comprises flat roll frame, side at flat roll frame arranges differential box and reductor, link to each other with the plain-barreled roll main shaft by Hooks coupling universal coupling, by a motor-driven, cross over two trestle correspondences in frame and install plain-barreled roll and lower plain-barreled roll, this traditional cold-rolled forming section rolling equipment should be at the two ends of each plain-barreled roll axle bearing block moving up and down is set, its transmission is the Hooks coupling universal coupling of a side joint differential box, when rolling wide cut high-strength steel sheet, usually needs the larger diameter of axle in order to guarantee rigidity, the diameter of axle can cause greatly again once that the rolling frame strengthened, the Meteorological of increase equipment is aspect transmission, for avoiding the difference in torque of both-end wheelbase, also need to increase the root shaft diameter, thereby cause drive mechanism huge, cause plain-barreled roll axle both sides discontinuity equalization, cause the moment of torsion lateral bending of cold-rolled forming section, forming part puts in place, and the defective such as stretch inconsistent.

The utility model content

The purpose of this utility model is to provide a kind of cold-rolled forming section rolling equipment that can solve the prior art defective.

The purpose of this utility model is achieved through the following technical solutions; A kind of cold-rolled forming section rolling equipment, comprise frame, upper plain-barreled roll and lower plain-barreled roll, be separately installed with a synchronization speed reducer on the frame both sides, two reductors are by same driven by motor, the output gear of each reductor respectively with the lower plain-barreled roll gear engagement at lower plain-barreled roll axle two ends, the lower plain-barreled roll gear at lower plain-barreled roll axle two ends again respectively with the upper plain-barreled roll gear engagement at upper plain-barreled roll axle two ends.

Further, the kind of drive of described motor and reductor is the driving-belt transmission.

Further, described motor is arranged at the centre of two reductors.

The utility model compared with prior art its advantage is: the utility model is by installing respectively a reductor at the frame two ends, and this reductor is by same motor-driven, guarantee that roll shaft two ends rotating speed is identical, can be used for producing the product of wide cut more than two meters, greatly reduce overall structure, reduced cost.

Description of drawings

Fig. 1 is cold-rolled forming section rolling equipment structural representation of the present utility model.

The specific embodiment

In order to make the purpose of this utility model, technical scheme and advantage clearer, below in conjunction with drawings and Examples, the utility model is further elaborated.Should be appreciated that specific embodiment described herein only in order to explaining the utility model, and be not used in restriction the utility model.

See also Fig. 1, Fig. 1 is cold-rolled forming section rolling equipment structural representation of the present utility model, as shown in Figure 1, a kind of cold-rolled forming section rolling equipment of the present utility model, comprise frame 1, upper plain-barreled roll 2 and lower plain-barreled roll 3, be separately installed with a reductor 4 on frame 1 both sides, two reductors 4 are driven by same motor 8, the output gear 5 of each reductor 4 respectively with lower plain-barreled roll gear 6 engagement at lower plain-barreled roll axle two ends, the lower plain-barreled roll gear 6 at lower plain-barreled roll axle two ends again respectively with upper plain-barreled roll gear 7 engagement at upper plain-barreled roll axle two ends, between described motor 8 and the reductor 4 with driving-belt 9 transmissions, described motor 8 be arranged at two reductors 4 between.

The utility model drives the reductor 4 that frame 1 both sides arrange by same motor 8, realize the synchronized rotation of two reductors 4, when two reductors 4 synchronously the time, can drive lower plain-barreled roll 3 two ends by output gear 5 rotates with angular speed, and lower plain-barreled roll gear 6 respectively with upper plain-barreled roll gear 7 engagements at upper plain-barreled roll axle two ends, and then realized that upper plain-barreled roll 2 two ends rotate with angular speed, and guarantee that roll shaft two ends rotating speed is identical, avoided the different and roll shaft distortion that produces of roll shaft two ends velocity of rotation.Can be used for producing the product of wide cut more than two meters, greatly reduce overall structure, reduce cost.

The above only is preferred embodiment of the present utility model; not in order to limit the utility model; all any modifications of within spirit of the present utility model and principle, doing, be equal to and replace and improvement etc., all should be included within the protection domain of the present utility model.
