Abstract
The utility model provides a roller way buffer device between tandem rolling extracted pipes. The device comprises a plurality of roller ways suspended and fixed under a roller way beam through bolts, the roller ways are arranged at equal intervals, shock pads are arranged at the positions of each bolt for suspending and fixing the roller ways and the roller way beam, and are made of polyurethane material. The utility model has the advantages that by adopting the roller way buffer device, the service life is prolonged, no shutdown is generated during roller way replacing, the default of unqualified product caused accordingly is eliminated, and the production efficiency is improved.
Description
Technical field
The utility model roller-way device is a kind of transmission equipment of rolled steel tube, is that tandem rolling in the rolled steel tube process takes off the roller-way buffer unit between the pipe.
Background technology
Generally in steel pipe's production, transport transmission by the roller-way beam between tandem mill and the winding arbor extraction press, it mainly acts on is that the hollow forging of support belt plug enters winding arbor extraction press and finishes the plumber's process of planting of taking off, as shown in Figure 1, this structure is made up of a rigidity roller-way beam and eight roller-ways that are suspended on its underpart, second, five, eight adjustment piece that the roller-way bottom is the depressing table beam wherein, the spacing of eight roller-ways does not wait, and roller shaft is provided with spring to two Side.After roller-way is impacted, can carry out axial float, impact to alleviate.But owing to frequently impacted, make the spring fatigue of two Side and intensity reduces, just need change roller-way every two days.Thereby, not only cause stopping production, but also the tube product quality is exerted an influence, cause accumulative total to shut down thus general every month and reach six hours, the concave defect percent defective that draws that is caused by the roller-way damage is 0.54%.
Summary of the invention
For solving the problem that exists in the above-mentioned technology; the purpose of the utility model roller-way device provides the buffer unit that a kind of tandem rolling takes off roller-way between the pipe, reduces the impact to the roller-way spring, prolongs the service life of roller-way; reduce downtime, eliminate because roller-way damages the waste product that produces.
For achieving the above object, technical solution of the present utility model provides a kind of tandem rolling and takes off roller-way buffer unit between the pipe, this device includes a plurality of roller-ways that hang the below that is fixed on the roller-way beam by bolt, wherein: described a plurality of roller-ways are set to equidistant arrangement, hang fixing bolt place and be provided with beam between described each roller-way and roller-way beam.
The a plurality of roller-ways that are provided with below the roller-way beam are five.
Described beam is that polyurethane material is made.
The effect of the utility model roller-way buffer unit is the service life of having improved roller-way; do not change the downtime of roller-way; roller-way is not damaged; avoided drawing concave defect owing to roller-way damages to produce; novel roller-way buffer unit has alleviated the impact of plug and steel pipe internal-surface simultaneously; produce thereby eliminated the recessed waste product defective of drawing that therefore causes, significantly improved production efficiency and tube quality.Eliminate the downtime of causing thus fully and drawn the concave defect waste product.

The specific embodiment
Reaching embodiment in conjunction with the accompanying drawings is illustrated the roller-way buffer unit that tandem rolling of the present utility model takes off between the pipe.
It is the transformation of implementing on original roller-way beam that tandem rolling of the present utility model takes off the roller-way buffer unit that the tandem rolling between plumber's preface takes off between the pipe, original roller-way is by four bolts roller-way 2 to be hung the below that is fixed on roller-way beam 4, and the roller-way height does not change.
As shown in Figure 2, the structure that this tandem rolling takes off the roller-way buffer unit between the pipe includes a plurality of roller-ways that hang the below that is fixed on the roller-way beam by bolt, and described a plurality of roller-ways 2 are set to equidistant arrangement, and a plurality of roller-ways 2 that are provided with below the roller-way beam are five.Hang fixing bolt place and be provided with beam 1 between described each roller-way 2 and roller-way beam 4, described beam 1 is made for polyurethane material.
Above-mentioned new structure still adopts the mode that is connected and fixed of bolting, at the following square bolt place of each roller-way 2 beam 1 of polyurethane material is installed, and has removed second, five, eight roller-way among original Fig. 1.As shown in Figure 2, the direction of arrow is rolling direction among the figure, the equidistant arrangement that makes the distance between five roller-ways keep basically identical, and rolling transportation transmits in the hollow forging process and operates steadily.When having plug ground hollow forging by this roller-way buffer unit, except that the spring play of roller-way both sides, the distortion of roller-way compression shock absorption pad is with the shock loading of buffering to roller-way.Because beam has the favorable linearity curve, when steel pipe by after can automatically restore to initial position, the roller-way height is consistent, the influence that before having eliminated steel pipe's production and quality has been caused.
This tandem rolling takes off the big transformation that the roller-way buffer unit between the pipe does not carry out existing equipment, after increasing the elastic polyurethane beam, with less cost, has obtained the better economic income.
Claims (3)
