A connecting mechanism and a hydraulic ram are equipped on the machine frame, the expander is driven by the hydraulic ram through the connecting mechanism, the expander is connected on the hydraulic ram through the working bushing, the expander consists of an expanding head, a sliding block, an expanding block, a positioning disk, a connecting nut, and a pull rod, the utility model has advantages of simple structure, compact structure, small volume, cheap price, and is a moveable expanding machine suitable to be used by the steel pipe manufacturer and the construction unit.
Description
Technical field
The removable expanding machine of the utility model belongs to the steel pipe manufacture field, particularly relates to a kind of machinery that steel pipe is carried out hole enlargement.
Prior art
Steel pipe has arrived the job site will carry out the butt joint of steel end, promptly the method for the pipe end of steel pipe with butt welding is linked together, if the pipe end of steel pipe is not round or girth is different, can cause a lot of inconvenience to site operation.General expanding machine all is installed on the production procedure line, and volume is very huge,
Because distortion such as pipe end depression appear causing because of collision in steel pipe sometimes in transportation and handling procedure, also have some steel pipes in being issued to the job site course of conveying, also can occur sometimes causing the pipe end depression in addition because of collision.The job site generally use to mouthpart because its different structure, can not eliminate pipe end dimensional defects and cirrhosis, therefore be that this steel pipe is retracted factory's hole enlargement generally speaking, these steel pipes are withdrawn into tubulation unit again, must cause the very big wasting of resources and delay many times, conventional in addition expanding machine can't carry out hole enlargement to bend pipe, because conventional expanding machine all moves centering by steel pipe, bend pipe is to be difficult to mobile and centering.
The utility model content
The purpose of this utility model is to avoid the deficiencies in the prior art part, and provides a kind of conveniently moving, removable expanding machine simple to operate.
The purpose of this utility model reaches by following measure, it is to utilize cone hole enlargement head, to the pipe end hole enlargement, reach the target of eliminating steel pipe sizes and shape defect, for good condition is created in on-the-spot steel pipe butt joint, it is formed by dilating device, work sleeve, oil cylinder, support and little Hydraulic Station.Bindiny mechanism and hydraulic jack are set on frame, hydraulic jack drives by bindiny mechanism and dilates device, little Hydraulic Station provides pressure oil for oil cylinder, dilating device is connected on the oil cylinder by the work sleeve, dilate device by hole enlargement head, slide block, dilate piece, positioning disk, coupling nut and pull bar and form, bindiny mechanism is made up of socket and pull bar, pull bar is installed in the socket, hydraulic jack is connected on the pull bar, and the pull bar other end is connected on the hole enlargement head.Pull bar is in the work sleeve, pull bar links together by coupling nut and hole enlargement head, oil cylinder is connected with pull bar, the hole enlargement head is a regular polygon cone, be connected with T type key between hole enlargement head and the slide block, be connected with screw between hole enlargement piece and the slide block, end at the close sleeve of slide block has positioning disk, T is connected with the type key between slide block and the positioning disk, make that slide block can only be along the positioning disk radial motion, when the motion of oil cylinder pulling pull bar, be connected hole enlargement head on the pull bar along with the pull bar axially-movable, force slide block on the hole enlargement head of cone-shaped with dilating piece, dilate device caliber to steel tube end part in steel pipe and dilate, reach the moulding of eliminating pipe end along the positioning disk radial motion, the internal stress that welding causes and the pipe end ovality and the diameter of customer requirement.And this expanding machine adopts a hole enlargement mobile centering pipe end, can satisfactorily resolve the problem of bend pipe end hole enlargement.
The utility model is simple in structure, compactness, and volume is little, and low price is a kind of removable expanding machine that is suitable for steel pipe manufacturing firm and the use of pipeline construction unit.
