In view of this, the present invention, for solving the problems of the technologies described above, provides a kind of steel pipe bender, and this bender for power, by improving the drive mechanism of Power output, provides powerful folding force with little cylinder.
Object of the present invention is achieved through the following technical solutions:
A kind of steel pipe bender, for bending steel pipe, comprise frame, the cylinder be fixed in frame, the trident component block be connected with cylinder output, the foldable component that is connected with trident component block; Described trident component block is the flat plate with three connection bumps, three connection bumps is equipped with through hole and is connected by removable rotating shaft with cylinder output, foldable component, frame respectively; Described foldable component comprises the connecting portion be connected with above-mentioned trident component block, double V-shaped folded block, the bending bearing rod that be horizontally placed on double V-shaped folded block on fastening with connecting portion.
Described double V-shaped folded block comprises two V-blocks be arranged in parallel and connects the portion that is connected of these two V-blocks, described in be connected portion and connecting portion be rigidly connected; Described V-block is provided with multiple round tube hole, and bending bearing rod both sides are provided with screw thread, and bending bearing rod is crossed round tube hole and locked by threaded fastener.
Described frame is provided with guide rail, and the portion of being connected is provided with guide wheel, and described guide wheel is sleeved on guide rail.
Described frame is provided with cylinder and installs screens, and this cylinder is installed screens and comprised lower fixing screens, upper adjustable screens and regulate the adjustment wheel disc of adjustable screens on this.
The present invention compared to the beneficial effect of prior art is:
This bender with little cylinder for power, by improving the drive mechanism of Power output, namely adopt trident component block as the drive disk assembly of the Power output of cylinder, the active force then finally acted on foldable component is cylinder outputting power and frame making a concerted effort to the reaction force of trident component block, for foldable component bending steel pipe provides powerful folding force.
Accompanying drawing explanation
The invention will be further described to utilize accompanying drawing, but the embodiment in accompanying drawing does not form any limitation of the invention.
Fig. 1 is the overall structure figure of steel pipe bender of the present invention.
Fig. 2 is the blown-up partial detail of steel pipe bender of the present invention.
Fig. 3 is the force analysis figure of the trident component block of steel pipe bender of the present invention.
Detailed description of the invention
The present invention to be described in further detail below in conjunction with accompanying drawing and embodiment for the ease of it will be appreciated by those skilled in the art that.
Please refer to Fig. 1-3, the embodiment of the present invention comprises:
A kind of steel pipe bender, for bending steel pipe 01, comprise frame, the cylinder 1 be fixed in frame, the trident component block 2 be connected with cylinder 1 output, the foldable component that is connected with trident component block 2; Trident component block 2, for having the flat plate of three connection bumps, three connection bumps is equipped with through hole and is connected by removable rotating shaft with cylinder output, foldable component, frame respectively; Foldable component comprises the connecting portion be connected with above-mentioned trident component block 2, double V-shaped folded block, the bending bearing rod 31 that be horizontally placed on double V-shaped folded block on fastening with connecting portion.
Double V-shaped folded block comprises two V-blocks be arranged in parallel 32 and connects the portion that is connected 33 of these two V-blocks, and the portion 33 that is connected is rigidly connected with connecting portion; V-block 32 is provided with 4 round tube holes, and bending bearing rod 31 both sides are provided with screw thread, and bending bearing rod 31 is crossed round tube hole and locked by threaded fastener 34.
Frame is provided with guide rail 41, and the portion 33 that is connected is provided with guide wheel 42, and guide wheel 42 is sleeved on guide rail 41.
Frame is provided with cylinder and installs screens, and this cylinder is installed screens and comprised lower fixing screens 51, upper adjustable screens 52 and regulate the adjustment wheel disc 53 of adjustable screens 52 on this.
This bender with little cylinder for power, by improving the drive mechanism of Power output, namely adopt trident component block as the drive disk assembly of the Power output of cylinder, the active force then finally acted on foldable component is cylinder outputting power and frame making a concerted effort to the reaction force of trident component block, for foldable component bending steel pipe provides powerful folding force.
As shown in the figure, power F1 is the power output of cylinder, and power F2 is the reaction force of frame to trident component block, and power F is making a concerted effort of power F1 and power F2.Because cylinder output and horizontal plane form an angle, therefore the direction of power F1 is also certain angle obliquely; Make a concerted effort for convenience of calculating, the power F2 ' marked in figure is power F2.According to the force analysis of this figure, indicate by trident component block very intuitively, due to power F2 and vertical plane angle less, therefore very little power F1, can form the very large F that makes a concerted effort, for foldable component provides powerful bending power with power F2.
Foldable component is by two V-blocks be arranged in parallel and the portion that is connected connecting these two V-blocks, and V-block is provided with multiple round tube hole, bending bearing rod both sides are provided with screw thread, bending bearing rod is crossed round tube hole and is locked by threaded fastener, user can be according to actual needs, for required different bending angle, in 4 round tube holes, select most suitable expansion bending work, applied widely.
Cylinder is installed screens and is comprised lower fixing screens, upper adjustable screens and regulate the adjustment wheel disc of adjustable screens on this; By the optimum position of adjusting cylinders, make cylinder output in time stretching out the end of stroke, trident component block is in immediately below foldable component, namely now frame to foldable component
Finally should be noted that; above embodiment illustrates technical scheme of the present invention; but not limiting the scope of the invention; although done to explain to the present invention with reference to preferred embodiment; those of ordinary skill in the art is to be understood that; can modify to technical scheme of the present invention or equivalent replacement, and not depart from essence and the scope of technical solution of the present invention.
