Abstract

The utility model discloses a wide cold-formed sectional steel flat roll frame comprising a cold-formed sectional steel flat roll frame, wherein the excircles of the upper part of an upper flat roll and the lower part of a lower flat roll are respectively and rotatably contacted and provided with a support break roll; and the upper and lower support break rolls are respectively arranged and fixed on upper and lower cross beams of the frame. The utility model has the advantages that the more than two-meter wide products can be produced, the overall structure is greatly reduced, and the manufacturing cost is lowered.

Description

Wide cut cold-rolled forming section plain-barreled roll frame

Technical field:

The utility model relates to mechanical driving device, and the particularly a kind of transmission that can strengthen the plain-barreled roll axle is turned round hard iron, prevented the wide cut cold-rolled forming section plain-barreled roll frame of plain-barreled roll axle generation deflection deformation.

Background technology:

Existing cold-rolled forming section plain-barreled roll frame is to be provided with differential box, reductor memorial archway shape frame one side, is connected with the plain-barreled roll main shaft by Hooks coupling universal coupling, by a motor-driven, in two trestle correspondences of leap on the frame plain-barreled roll and following plain-barreled roll is installed.This traditional cold-rolled forming section plain-barreled roll frame, because bearing block moving up and down is set at the two ends of each plain-barreled roll axle, its transmission is the Hooks coupling universal coupling of a side joint differential box, when rolling wide cut high-strength steel sheet, in order to guarantee that rigidity needs the larger axis footpath usually, can cause then when the diameter of axle is big that roll stand strengthens, increase equipment drops into expense; Aspect transmission, for avoiding the difference in torque of both-end axle, 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, defective such as moulding is not in place, and it is inconsistent to stretch.

Summary of the invention:

The purpose of this utility model provides a kind of driving torque that can effectively strengthen plain-barreled roll, prevents plain-barreled roll axle generation deflection deformation, adapts to the plain-barreled roll frame of wide cut cold-rolled forming section.

Task of the present utility model is finished as follows, it includes a cold-rolled forming section plain-barreled roll frame, it is characterized in that: rotate respectively contact on the bottom cylindrical of the top of last plain-barreled roll and following plain-barreled roll a support pair roller is installed, last lower support pair roller is fixed on respectively on the lower and upper cross-member of frame.Be separately installed with a synchronization speed reducer at the frame two ends, two reductors are driven through driving-belt by a motor, the output gear of each reductor respectively with the mistake gears engaged of frame both sides, each is crossed gear and is engaged on down respectively again on the gear of plain-barreled roll axle both sides, the gear at following plain-barreled roll two ends again respectively with the gears engaged at last plain-barreled roll axle two ends.The utility model can be used for producing the product of wide cut more than two meters, has reduced overall structure greatly, has reduced the cost cost.

Description of drawings:

Fig. 1 is a structural representation of the present utility model, and Fig. 2 is the local installation side view of upper and lower plain-barreled roll.

The specific embodiment:

Further describe embodiment in conjunction with above accompanying drawing, the utility model is improvements over the prior art, rotate respectively contact on the bottom cylindrical of the top of last plain-barreled roll 5 and following plain-barreled roll 7 a support pair roller 6 is installed, upper and lower support pair roller is fixed on respectively on the lower and upper cross-member of frame 8.Be separately installed with a synchronization speed reducer 1 at the frame two ends, two reductors are driven through rotating band respectively by a motor 9, the output gear of each reductor respectively with the frame both sides cross gear 2 engagements, each is crossed gear and is engaged on down respectively again on the lower gear 3 of plain-barreled roll axle both sides, and the lower gear at following plain-barreled roll two ends 4 meshes with cogging of last plain-barreled roll axle two ends respectively again.Drive the reductor 1 of frame both sides during work by motor 9, driven wheel on each reductor is through intermeshing lower gear 3 on plain-barreled roll 7 and the last plain-barreled roll 5 under gear 2 drives and cog 4, making up and down, plain-barreled roll relatively rotates, carry out work, owing to set up last lower support pair roller, improve the moment of torsion of plain-barreled roll axle up and down greatly, can adapt to processing the products such as stainless steel wave card of wide cut more than two meters.To organize such plain-barreled roll frame series connection more, and the power shaft of its both sides reductor is connected with shaft coupling, can form the cold-rolled forming section unit of any sortie, can be used for continuous processing operation.

Claims
