Abstract
A steel arch cold bending machine comprises a steel machining platform, a top wheel driven by an operating cylinder to do telescopic movement is arranged on the steel machining platform, the top wheel is in contact with one side of a workpiece, and two limiting idler wheels are arranged on the other side of the workpiece. The top wheel is arranged between the two limiting idler wheels, and at least one limiting idler wheel is connected with a drive motor. By means of the structure, the steel arch cold bending machine can conveniently machine a steel arch in a cold bending mode, due to the fact that the drive motor drives the limiting idler wheels to rotate, when the workpiece moves in a reciprocating mode on a leveling bracket, the steel arch cold bending machine is favorable for achieving a relatively high size accuracy. By means of the arrangement of the leveling bracket, the leveling bracket is favorable for reducing resistance when the workpiece moves in a reciprocating mode, so that the steel arch cold bending machine can further guarantee size accuracy of workpiece machining.
Description
Technical field
The utility model relates to the cold-working manufacture field, particularly a kind of steel bow member forming mill that is used for the making of steel bow member.
Background technology
In steel bow member process, in the past general adopt manual work to be aided with burning torch to cut after welding production again, not only labour intensity is big; At the bottom of the efficient; And converted products is yielding, does not reach required machining accuracy, can't satisfy current construction speed and quality requirement.
Summary of the invention
The utility model technical problem to be solved provides a kind of steel bow member forming mill, can be with method machined steel bow member easily, and working (machining) efficiency is high, and labour intensity is low.
For solving the problems of the technologies described above, the technical scheme that the utility model adopted is: a kind of steel bow member forming mill comprises the steel processing platform; The steel processing platform is provided with by operating cylinder and drives flexible top wheel; One side contacts of top wheel and workpiece, the opposite side of workpiece is provided with two limited rollers; The top wheel is between two limited rollers, and at least one limited roller is connected with drive motors.
Also be provided with the leveling carriage of a plurality of supporting workpieces that are used to roll on the described steel processing platform.
Described leveling carriage is the cylinder that two ends are provided with rolling bearing.
The axis of described a plurality of leveling carriages overlaps with the RADIAL of workpiece circular arc to be processed.
The steel bow member forming mill that the utility model provides; Through adopting above-mentioned structure, can rotate through the drive motor drives limited roller easily with the mode machined steel bow member of clod wash; Workpiece is moved back and forth on the leveling carriage, help reaching high dimension precision.The leveling carriage that is provided with helps reducing the resistance of workpiece when moving back and forth, thereby further guarantees the dimensional accuracy of workpiece processing.
Through being applied to tunnel engineering, but proving and use this device short time, high efficiency to process the bow member that meets design and construction requirement, ensured driving progress and construction safety.
Description of drawings
Below in conjunction with accompanying drawing and embodiment the utility model is described further:
Fig. 1 is the structural representation of the utility model.
Among the figure: leveling carriage 1, steel processing platform 2, top wheel 3, operating cylinder 4, hydraulic oil pump motor 5, limited roller 6, drive motors 7, workpiece 8.
The specific embodiment
In Fig. 1, a kind of steel bow member forming mill comprises steel processing platform 2; Steel processing platform 2 is provided with by operating cylinder 4 and drives flexible top wheel 3; One side contacts of top wheel 3 and workpiece 8, the opposite side of workpiece 8 is provided with two limited rollers 6; Top wheel 3 is between two limited rollers 6, and at least one limited roller 6 is connected with drive motors 7.
Also be provided with the leveling carriage 1 of a plurality of supporting workpieces 8 that are used to roll on the described steel processing platform 2.
Described leveling carriage 1 is provided with the cylinder of rolling bearing for two ends.
The axis of described a plurality of leveling carriages 1 overlaps with the RADIAL of workpiece 8 circular arcs to be processed.Described circular arc to be processed is the circular arc that workpiece 8 finally processes, and structure makes the axis of leveling carriage 1 vertical with the direction of motion of workpiece 8 as much as possible thus, reduces the sliding friction of the cylinder of workpiece 8 and leveling carriage 1.
Add man-hour; Workpiece in this example 8 channel-section steels are placed on the leveling carriage 1, after limited roller 6 contacts, primer fluid pressure oil pump 5 systems; Hydraulic oil by hydraulic oil pump 5 outputs is controlled operating cylinder 4 expanding-contracting actions through overflow valve, electro hydraulic valve and point driving switch; Operating cylinder 4 stretches out, and the channel-section steel of required processing is advanced to limited roller fully contact, and makes channel-section steel bend to arch further; The forward or reverse drive motors 7 again, through the decelerator transmission, move around on leveling carriage 1 thereby drive limited roller 6 drive channel-section steels, until reaching required processing dimension.
