But, the weld pad roller that this brings does not at random design according to space and the adjustment characteristics thereof between three roll bending triggers, two lower rolls in the former, design single, complex structure, bulky, can't be installed to the position that needs, so this weld pad roller holds in the formula former in the spiral submerged welded pipe unit and can not use.
The utility model content
The problem that the utility model embodiment will solve provides a kind of weld pad roller that is used for holding in the spiral submerged welded pipe unit formula former, holds in the spiral submerged welded pipe unit and can not use in the formula former and cause the defective of poor welding quality to overcome weld pad roller in the prior art.
For achieving the above object, the technical scheme of the utility model embodiment provides a kind of weld pad roller that is used for holding in the spiral submerged welded pipe unit formula former, described weld pad roller is included in the running roller that the below connects hoist cylinder, the roller seat that is connected with hoist cylinder, hoist cylinder is fixed when can move up and down along the passage that roller seat provides and running roller is in the certain altitude position above it, the adjusting that moves up and down the mechanism that is adjusted of hoist cylinder, described running roller, hold in the formula former three-roll bending machine two rows cooperating between the distortion roller down in the size of hoist cylinder and roller seat and the spiral submerged welded pipe unit apart from K.
Wherein, K is 60～80 millimeters.
Wherein, K is 80～120 millimeters.
Wherein, K is 120～160 millimeters.
Wherein, K is 160～200 millimeters.
Wherein, K is 200～250 millimeters.
Compared with prior art, the technical solution of the utility model has following advantage:
The utility model is in the steel pipe forming process, the weld pad roller becomes the certain pre-pressing force of groove part meshing point for steel pipe, make steel pipe become groove part to mesh smoothly and the elimination misalignment, bridge need not be swung and caliber can not change, and when engagement changes, adjusts the pressure of hydraulic hand-pump, change pre-pressing force, become the groove part engagement to adapt to steel pipe, still can obtain good one-tenth groove part and suitable steel pipe caliber, thereby also obtain good welding quality.

Fig. 2 is used for holding in the spiral submerged welded pipe unit right view of the weld pad roller of formula former for the utility model embodiment a kind of;
Fig. 3 is used for holding in the spiral submerged welded pipe unit vertical view of the weld pad roller of formula former for the utility model embodiment a kind of.
The specific embodiment
Below in conjunction with drawings and Examples, the specific embodiment of the present utility model is described in further detail.Following examples are used to illustrate the utility model, but are not used for limiting scope of the present utility model.
The utility model embodiment a kind of is used for holding in the spiral submerged welded pipe unit structure such as Fig. 1, Fig. 2 and shown in Figure 3 of the weld pad roller of formula former, and the weld pad roller when present embodiment is K=160mm is applicable to that the K value equals 160～200mm scope.In depending on, the size of K value holds the size that three roll bending triggers bear deformation force in the formula former.Holding the weld pad roller that the formula former uses in of the present utility model is divided into: K60 (scope of application is 60～80mm), K80 ((scope of application is 80～120mm), K120 (scope of application is 120～160mm), K160 (scope of application be 160～200mm) and K200 (scope of application is 200～250mm) totally five kinds.
The structure of every kind of weld pad roller is basic identical, only change the size of running roller, hoist cylinder and roller seat, adjust flexibly principle and carry out the design of every kind of weld pad roller in line with making full use of space and weld pad roller according to the space between three roll bending triggers, two lower rolls in the size of K value and the former.The K value is three roll bending triggers, two lower rolls reflection of distance between its stress point when steel plate bending is out of shape in the molding welded steel pipes device.
Holding formula former special pad roller in the spiral submerged welded pipe unit is made up of running roller, roller frame, locking nut, hydraulic cylinder, slide, base, guiding mechanism and hand-hydraulic pumping plant etc.
Holding the formula former in the spiral submerged welded pipe unit is a kind of molding mode of tray formula in the three roll bending trigger bands, determine the three-roll bending machine two rows spacing between the distortion roller down according to the size of steel pipe caliber, wall thickness, material and the deformation force produced, both be generally called " K value ".In the present embodiment, according to the space between the distortion roller under three-roll bending machine two rows, design the diameter of running roller, the size of selecting bearing for use, design hydraulic cylinder diameter, guarantee the bearing capacity of running roller and hydraulic cylinder, become the needs of groove part engagement when adapting to the steel pipe moulding to greatest extent; According to the three-roll bending machine two row distance between the distortion roller roller seat down, determine the width of slide, the stability when guaranteeing the work of weld pad roller and adjust flexibly, convenient, the stable of weld pad roller is the key factor of steel pipe stable molding.
During work, present embodiment is " K " value according to the distance that two rows of three-roll bending machine in the make-up machine are out of shape down between the roller roller seat, the weld pad roller is divided into: " K60 ", " K80 ", " K120 ", " K160 " and five kinds of specifications such as " K200 ".After steel pipe moulding adjustment is finished, according to its " K value " size, select the weld pad roller of corresponding size for use, the running roller position of weld pad roller is put into steel pipe becomes groove part meshing point place, by guiding mechanism lower bottom base is put into suitable position and fixing, start hydraulic hand-pump and make the weld pad roller press closer at steel pipe to become on the meshing point of groove part, become groove part and caliber to change according to steel pipe in the production, the pressure of suitably adjusting hydraulic hand-pump is to satisfy the demand.In ordinary production, becoming the engagement of groove part, the pressure of hydraulic hand-pump according to steel pipe is often to adjust.
The weld pad roller of present embodiment is to design in conjunction with the actual conditions of steel pipe moulding, in the steel pipe forming process, the weld pad roller becomes the certain pre-pressing force of groove part meshing point for steel pipe, make steel pipe become groove part to mesh smoothly and the elimination misalignment, bridge need not be swung and caliber can not change, when engagement changes, adjust the pressure of hydraulic hand-pump, change pre-pressing force, become the groove part engagement to adapt to steel pipe, still can obtain good one-tenth groove part and suitable steel pipe caliber, thereby also obtain good welding quality.
