Abstract
The utility model relates to the field of non-standard pipe bending devices, in particular to a hand-operated pipe bending machine. The hand-operated pipe bending machine is characterized by comprising a mould shaped like an idler wheel, a driven wheel, a connecting rod and fixing bolts; an arc-shaped groove surrounding the whole side face is formed in the radial side face of the driven wheel, and an arc-shaped groove with the same radius as the arc-shaped groove formed in the side face of the driven wheel is formed in the radial side face of the mould; two parallel through holes, namely, the inner through hole and the outer through hole, are formed in one end of the connecting rod, a supporting plate is arranged on the lower portion of the inner through hole, and a through hole corresponding to the inner through hole is formed in the supporting plate; the mould is arranged between the connecting rod and the supporting plate through one fixing bolt in a rotatable mode, and the driven wheel is arranged below the connecting rod in a rotatable mode through the other fixing bolt and is opposite to the mould. Due to the adoption of the design, the hand-operated pipe bending machine is small in size, simple in structure and capable of meeting the working requirements of small and thin pipelines for various bending radiuses and continuous bending.
Description
Technical field
The utility model relates to non-standard bent pipe apparatus field, is specially a kind of manual tube bender.
Background technology
In the time making small-sized hydraulic station fuel tank (as the fuel tank of 24ml capacity); The size of Hydraulic Station pipe arrangement pipeline is correspondingly corresponding dwindling (if line size is 12mm*2mm) also; Although use traditional automatic pipebender can meet the diameter requirement of small diameter pipeline, cannot meet the requirement of bending radius and the continuous bend of overall pipeline; And the space that is generally used for installing undersized Hydraulic Station fuel tank like this and supporting pipeline is very narrow and small, use commercially available finished product elbow certainly will increase a large amount of weld seams, thereby the quality of whole pipeline is just difficult to control.
Summary of the invention
The purpose of this utility model is, a kind of manual tube bender that pipe with small pipe diameter, bending radius pipeline little, continuous bend require that can be applicable to is provided.
In order to achieve the above object, the utility model is achieved in that
A kind of manual tube bender; It comprises the mold and driven pulley, connecting rod and the set bolt that are roller shape; The radius of described driven pulley is not more than 70mm, and driven pulley central authorities have axially extending bore, and driven pulley radial side has the circular groove arranging around whole side, and the radius of described circular groove is not more than 7mm; The radius of described mold is not more than 60mm, and mold central authorities have axially extending bore, and mold radial side has the circular groove arranging around whole side, and the radius of described circular groove is identical with the radius of the circular groove that driven pulley side is offered; Connecting rod one end has inside and outside two parallel through holes, and interior side through hole bottom is provided with gripper shoe, has and the corresponding through hole of interior side through hole in gripper shoe; Mold is located between connecting rod and gripper shoe with being threaded of through hole in interior side through hole and gripper shoe rotationally by bolt, and driven pulley is located at connecting rod below relative with mold rotationally with being threaded of outer side through hole by bolt.
The utility model adopts above-mentioned design, and its volume is small and exquisite, simple in structure, and low and practical flexible to fixing point requirement, can adapt to line size is the various bending radius of 12mm*2mm pipeline and the job requirement of continuous bend.
Accompanying drawing explanation
Fig. 1 is front view of the present utility model.
Fig. 2 is top view of the present utility model.
The specific embodiment
Further illustrate the utility model by specific embodiment below.
As shown in Figure 1 and Figure 2, a kind of manual tube bender; It comprises the mold 3 and driven pulley 4, connecting rod 1 and the set bolt 6 that are roller shape; The radius of described driven pulley 4 is 70mm, and driven pulley 4 central authorities have axially extending bore, and driven pulley 4 radial side have the circular groove arranging around whole side, and the radius of described circular groove is 7mm; The radius of described mold 3 is 60mm, and mold 3 central authorities have axially extending bore, and mold 3 radial side have the circular groove arranging around whole side, and the radius of described circular groove is identical with the radius of the circular groove that driven pulley 4 sides are offered; Connecting rod 1 one end has inside and outside two parallel through holes, and interior side through hole bottom is provided with gripper shoe 2, has and the corresponding through hole of interior side through hole in gripper shoe; Mold 3 is by bolt 6 with being threaded of through hole in interior side through hole and gripper shoe 2 and be located at rotationally between connecting rod 1 and gripper shoe 2, and driven pulley 4 is located at connecting rod 1 below relative with mold rotationally with being threaded of outer side through hole by bolt 6.
As shown in Figure 2, when this bending machine uses, connecting rod is fixed on Working gantry, needing bending steel pipe to be fixed on manual tube bender, reserves bending size and bending radius and bending angle, manually move connecting rod, can bending put in place.
