Abstract
The utility model discloses a spiral bending device for a thin-wall flat oval tube. The spiral bending device for the thin-wall flat oval tube comprises a rack, a mandrel support, a mandrel and a bending wheel, wherein the mandrel support is installed on the rack, the mandrel is matched with the inner wall of the thin-wall flat oval tube in a sliding mode, the threaded end of the mandrel penetrates through a mandrel hole in the mandrel support, and can be fixed through a nut, a plurality of closing-up wheels which are installed on the rack and are matched with the thin-wall flat oval tube are arranged on the two side edges of the mandrel, the bending wheel is installed on a rotary shaft driven by a power source, the rotary shaft is installed on the rack, and enables the threaded groove surface on the bending wheel to face the lead-in direction of the thin-wall flat oval tube, and the rotary shaft moves in the axis direction of the rotary shaft when rotating, and moves for the distance of a lead after each circle of rotation. The spiral bending device for the thin-wall flat oval tube saves time and labor, and is small in deformation.
Description
Technical field:
The utility model is relevant with the helical buckling device, and is special relevant with thin-walled flattened oval pipe helical buckling device.
Background technology:
Bending machine kind in the market approximately is divided into two classes, and a class is the pipe bending machine, and another kind of is the square tube bending machine, and still, these type of bending machine great majority are that same plane is crooked, and spiral bending tube few in number also only limits to the bending of pipe.
The utility model content:
The purpose of this utility model be save time in order to provide a kind of, laborsaving, be out of shape little thin-walled flattened oval pipe helical buckling device.
The purpose of this utility model is achieved like this:
the utility model thin-walled flattened oval pipe helical buckling device, comprise frame, be contained in the mandrel bearing on frame, the mandrel that is slidably matched with thin-walled flattened oval inside pipe wall, bend wheel, the mandrel thread end is through in core axle hole on the mandrel bearing and can fixes by nut, the dual-side of mandrel have respectively a plurality of be contained on frame coordinate with thin-walled flattened oval pipe be close to wheel, bend wheel is contained on the rotating shaft that is subjected to the power source drive, rotating shaft is contained on frame and makes the thread groove on bend wheel import direction in the face of thin-walled flattened oval pipe, rotating shaft moves along the rotating shaft axis direction in rotation, the distance of the mobile helical pitch that often rotates a circle.。
Above-mentioned a plurality of being close to taken turns equidistant being contained on frame.
During the utility model work, with thin-walled flattened oval pipe be through on mandrel, both sides external be close to the wheel be close to, thin-walled flattened oval Guan Yiduan is stretched in the bend wheel helicla flute, thereby power source driven rotary axle rotates bend wheel is rotated, and bend wheel is bent into thin-walled flattened oval pipe the shape of helix tube when rotating, move forward with the helical pitch of helix, after bending is completed, the bend wheel opposite spin allows in type thin-walled flattened oval pipe automatically withdraw from bend wheel, completes time processing.
The utility model thin-walled flattened oval pipe helical buckling device can crooked thin-walled flattened oval metal tube, guarantees that little, the crooked inner ring of pipe fitting distortion is wrinkle resistant, does not cave inward, and saves time, laborsaving, improves bend pipe efficient; Reduce labour intensity; Improve the popularity that pipe fitting uses.
Description of drawings:
Fig. 1 is the utility model structural representation.
Fig. 2 is the right view of Fig. 1.
Fig. 3 is the top view of Fig. 1.
The specific embodiment:
Referring to Fig. 1～Fig. 3, the utility model thin-walled flattened oval pipe helical buckling device, the mandrel 4, the bend wheel 5 that comprise frame 1, be contained in mandrel bearing 2 on frame, be slidably matched with thin-walled flattened oval pipe 3 inwalls.The mandrel thread end is through in core axle hole on the mandrel bearing and can fixes by nut.The dual-side of mandrel have respectively a plurality of equidistant be contained on frame coordinate with thin-walled flattened oval pipe be close to wheel 6.Bend wheel is contained in by reductor 7 and is subjected on the rotating shaft 9 of motor 8 drives.Rotating shaft is contained on frame and makes the thread groove on bend wheel import direction in the face of thin-walled flattened oval pipe.Slide rail 10 on reducer shell and frame is slidably matched.Rotating shaft moves along the rotating shaft axis direction in rotation, the distance of the mobile helical pitch that often rotates a circle.
Claims (2)
1. thin-walled flattened oval pipe helical buckling device, it is characterized in that comprising frame, be contained in the mandrel bearing on frame, the mandrel that is slidably matched with thin-walled flattened oval inside pipe wall, bend wheel, the mandrel thread end is through in core axle hole on the mandrel bearing and can fixes by nut, the dual-side of mandrel have respectively a plurality of be contained on frame coordinate with thin-walled flattened oval pipe be close to wheel, bend wheel is contained on the rotating shaft that is subjected to the power source drive, rotating shaft is contained on frame and makes the thread groove on bend wheel import direction in the face of thin-walled flattened oval pipe, rotating shaft moves along the rotating shaft axis direction in rotation, the distance of the mobile helical pitch that often rotates a circle.
2. thin-walled flattened oval pipe helical buckling device as claimed in claim 1, is characterized in that a plurality of equidistant being contained on frame of wheel that are close to.
