The invention provides a multi-degree-of-freedom three-roller pipe manufacturing machine. The multi-degree-of-freedom three-roller pipe manufacturing machine comprises an upper compression roller and a pair of lower compression rollers, a workpiece is arranged between the upper compression roller and the lower compression rollers, lifting tables are connected to the lower portions of the lower compression rollers, the lifting tables of the two lower compression rollers are connected with one horizontal sliding table, the lower compression rollers and the lifting tables are connected through a ball bearing, or the lifting tables and the horizontal sliding table are connected through a ball bearing. The upper compression roller is connected with an air cylinder at the top through a stretching rod, wherein the upper compression roller is connected with the stretching rod through a ball bearing, or the stretching rod is connected with the air cylinder through a ball bearing. According to the multi-degree-of-freedom three-roller pipe manufacturing machine, the horizontal distance and the vertical distance between the upper compression roller and the lower compression rollers are adjusted, pipes with different pipe diameters and different thicknesses can be manufactured, the freedom degree is high, and convenience is brought to adjustment.
Description
Technical field
The present invention relates to tubulation apparatus field, specifically a kind of multiple degrees of freedom 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 and shaping four kinds of hydraulic press.
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 because machine construction reason forming force can only be applied to working roll two ends, in process, working roll inevitably produces deflection deformation, this distortion increases along with length and significantly increases, work roll diameter can only be increased at present solve, thus make machine capability be subject to the restriction of certain limit.
Summary of the invention
The present invention, in order to solve the problem of prior art, provides a kind of multiple degrees of freedom 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 present invention includes pressure roller and a pair lower compression roller, workpiece is placed between lower compression roller, lifting platform is connected with below described lower compression roller, the lifting platform of two lower compression rollers is connected with same horizontal slip platform, is wherein connected by ball bearing between lower compression roller and lifting platform or between lifting platform with horizontal slip platform; Described upper pressure roller, by the cylinders at expansion link and top, is wherein gone up between pressure roller and expansion link or between expansion link with cylinder and is connected by ball bearing.
Repacking is put middle lower compression roller and is not only comprised X-axis and Z axis two frees degree, and can also pass through the rotation of 360 °, ball bearing, upper pressure roller not only comprises Z axis one degree of freedom, also can pass through the rotation of 360 °, ball bearing.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 both sides are provided with workpiece transport band, and the edge of work is placed in above workpiece transfer device.Workpiece transfer device moves back and forth between sheet material raw material and pressure roller, steel plate is transported to the middle roll bending that carries out of three rollers shaping, realizes industrial production line.
Accompanying drawing explanation
Fig. 1 is structural representation of the present invention.
Detailed description of the invention
Below in conjunction with accompanying drawing, the invention will be further described.
Structural representation of the present invention 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: below described lower compression roller 3, be connected with lifting platform 2, the lifting platform 2 of two lower compression rollers 3 is connected with same horizontal slip platform 1, is wherein connected by ball bearing between lower compression roller 3 and lifting platform 2 or between lifting platform 2 with horizontal slip platform 1; Described upper pressure roller 6, by the cylinders of expansion link 7 with top, is wherein gone up between pressure roller 6 and expansion link or expansion link 7 is connected by ball bearing with between cylinder.
Repacking is put middle lower compression roller and is not only comprised X-axis and Z axis two frees degree, and can also pass through the rotation of 360 °, ball bearing, upper pressure roller not only comprises Z axis one degree of freedom, also can pass through the rotation of 360 °, ball bearing.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.
Described workpiece 4 both sides are provided with workpiece transport band 5, and workpiece 4 edge is placed in above workpiece transfer device 5.Workpiece transfer device 5 moves back and forth between sheet material raw material and pressure roller, steel plate is transported to the middle roll bending that carries out of three rollers shaping, realizes industrial production line.
Embody rule approach of the present invention is a lot, and the above is only the preferred embodiment of the present invention, should be understood that; for those skilled in the art; under the premise without departing from the principles of the invention, can also make some improvement, these improvement also should be considered as protection scope of the present invention.
