Abstract
The utility model provides a high degree of freedom three -roller tuber, including last compression roller and a pair of lower compression roller, the work piece is placed in between the upper and lower compression roller, lower compression roller below be connected with the elevating platform, the elevating platform of two lower compression rollers links to each other with same horizontal slip platform, the last compression roller cylinder that passes through telescopic link and top link to each other. The utility model discloses a tubulation can be carried out to level interval and vertical interval about the adjustment between the compression roller to the pipeline of the different thickness demands of different pipe diameters, the degree of freedom is high, convenient adjustment.
Description
Technical field
The utility model relates to tubulation apparatus field, specifically a kind of high-freedom degree three roller tuber.
Background technology
At present conventional heavy wall ERW, forming method be divided into bender to add abrasive tool moulding, veneer reeling machine are shaping, row-roll forming process
With hydraulic press shaping four kinds.
But bender adds abrasive tool moulding, row-roll forming process and hydraulic press these three kinds of methods of forming shaping, and not only equipment is huge, and energy consumption is high, and just must change corresponding mould once replacing specification, product specification more later stages grinding tool input cost is just also higher.Due to cost reason, almost nonstandard size pipe can not be produced.
Although the equipment investment of the roll bending method of forming is little, cost only has the 1/5-1/10 of above-mentioned three kinds, due to reasons in structure,
Length can only small-bore thick-walled seamless steel pipes at 3-6m and in can not producing.
Traditional bender adds abrasive tool moulding and hydraulic press these two kinds of forming methods shaping, due to workpiece and mould shaping be that face contacts, required briquetting pressure is high.But owing to being overall length uniform stressed, the linearity of steel pipe is very good.
Traditional roll bending method of forming owing to being linear contact lay between workpiece and shaping rod, so relative usage pressure is lower, but can only be applied to working roll two ends due to machine construction reason forming force, in process, working roll inevitably produces
Raw deflection deformation, this distortion increases along with length and significantly increases, and can only increase work roll diameter at present solves, thus makes machine capability be subject to the restriction of certain limit.
Utility model content
The utility model, in order to solve the problem of prior art, provides a kind of high-freedom degree three roller tuber, and carry out roll bending by three pressure rollers of high-freedom degree shaping, can prepare the pipeline of caliber, different-thickness, the free degree is high, easy to adjust.
The utility model comprises pressure roller and a pair lower compression roller, and workpiece is placed between lower compression roller, is connected with lifting platform below described lower compression roller, and the lifting platform of two lower compression rollers is connected with same horizontal slip platform; Described upper pressure roller is by the cylinders at expansion link and top.
Repacking is put middle lower compression roller and is comprised X-axis and Z axis two frees degree, and upper pressure roller comprises Z axis one degree of freedom.Level interval between upper pressure roller and lower compression roller is adjusted by horizontal slip platform, and the vertical interval between upper lower compression roller is adjusted by expansion link and top cylinder.By adjusting level interval between upper lower compression roller and vertical interval, can carry out tubulation for the pipeline of different tube diameters different-thickness demand, the free degree is high, convenient adjustment.
Further improvement, described workpiece two ends are connected with workpiece transfer device by hoist cable, and hoist cable is moved back and forth between sheet material raw material and pressure roller by workpiece transfer device, steel plate are transported to the middle roll bending that carries out of three rollers shaping, realize industrial production line.
Accompanying drawing explanation
Fig. 1 is the utility model structural representation.
Detailed description of the invention
Below in conjunction with accompanying drawing, the utility model is described in further detail.
The utility model structural representation as shown in Figure 1, comprise pressure roller 6 and a pair lower compression roller 3, workpiece 4 is placed between lower compression roller, it is characterized in that: be connected with lifting platform 2 below described lower compression roller 3, and the lifting platform of two lower compression rollers 3 is connected with same horizontal slip platform; Described upper pressure roller 6 is by the cylinders of expansion link 7 with top.Repacking is put middle lower compression roller and is comprised X-axis and Z axis two frees degree, and upper pressure roller comprises Z axis one degree of freedom.Level interval between upper pressure roller and lower compression roller is adjusted by horizontal slip platform, and the vertical interval between upper lower compression roller is adjusted by expansion link and top cylinder.By adjusting level interval between upper lower compression roller and vertical interval, can carry out tubulation for the pipeline of different tube diameters different-thickness demand, the free degree is high, convenient adjustment.
Workpiece two ends are connected with workpiece transfer device by hoist cable 5, and hoist cable is moved back and forth between sheet material raw material and pressure roller by workpiece transfer device, steel plate are transported to the middle roll bending that carries out of three rollers shaping, realize industrial production line.
The utility model embody rule approach is a lot; the above is only preferred embodiment of the present utility model; should be understood that; for those skilled in the art; under the prerequisite not departing from the utility model principle; can also make some improvement, these improvement also should be considered as protection domain of the present utility model.
