Abstract
The utility model discloses a hand-operated pipe bending apparatus. A supporting part I (3) is fixedly connected to one side of an upper side of a support (1), and a chassis (7) is fixedly connected to the other side of the upper side of the support (1). A supporting part II (4) is fixedly connected to a middle part of the chassis (7), an outer side of which is movable connected with a horizontal U-shaped rotating rack (9). A handle (8) is connected to an enclosed end of the horizontal U-shaped rotating rack (9). And an inner part of the horizontal U-shaped rotating rack (9) is respectively connected with a roller I (10) and a roller II (11) by a fixing shaft I (5) and a fixing shaft II (6). The roller I (10) and the roller II (11) are respectively provided with two sets of centripetal ball bearings. Thereby the process provided in the utility model is simple, and by using the hand-operated pipe bending apparatus, which is suitable for bending the stainless steel seamless tubes, the surface of the bended product can be smooth.
Description
Technical field:
The utility model relates to a kind of swan neck system, particularly a kind of manual swan neck system that is used for stainless steel elbow.
Background technology:
At present, in the product processing of industries such as China's food, medicine, chemical industry, electronics, often can use the plate and frame filter, be used for to the small impurity of each class I liquid I filter, clarification and purification processes.Being connected between the inlet of this filter and each arm realizes through countless " U type pipes "; Wherein " U type pipe " parts are that stainless steel seamless pipe with φ 25 * 3 bends and forms; Angle of bend is 180 °, and bending radius is R42, as adopts traditional hand-hydraulic pipe bender to process; The bending radius of its mould is 2D (R50), 90 °≤α of angle of bend＜180 °.Because the strain in the stainless steel tube process, last product processed angle of bend can only reach 130 °, and bending radius is R50; Do not reach designing requirement, need carry out secondary operations, complex procedures; Existing swan neck system is the effect lower stress distortion at hydraulic cylinder, owing in the process of ten thousand strings of cash, produce sliding friction, product " U type pipe " is in the process of bending; The outer rim of pipe breaks away from mould easily and causes the outside to play drum, and inside tube is prone to form fold, makes the product of manufacturing defective.
Summary of the invention:
The purpose of the utility model is to solve the weak point that above-mentioned prior art exists, provide a kind of can be once cold-formed and product processed smooth surface, the simple manually swan neck system of operation.
The purpose of the utility model realizes through following technical scheme: a kind of manual swan neck system; Be made up of bearing, it is characterized in that described bearing upper end one side is fixedly connected support member I, opposite side is fixedly connected the chassis; The middle part on chassis is fixedly connected support member II; Its outside flexibly connects rotating turret, and rotating turret is horizontal " U " shape, at the end connection handle of sealing; Portion is connected roller I and roller II respectively through fixed axis I and fixed axis II within it, and two cover radial ball bearings are respectively arranged in roller I and the roller II.
Described support member I and support member II are " L " shape, and there is the circular hole of a φ 28 its upper end, and these two circular holes point-blank.
The utility model compared with prior art has the following advantages:
Because adopt bearing upper end one side to be fixedly connected support member I, opposite side is fixedly connected the chassis, the middle part on chassis is fixedly connected support member II; Its outside flexibly connects rotating turret; Rotating turret is horizontal " U " shape, and at the end connection handle of sealing, portion is connected roller I and roller II respectively through fixed axis I and fixed axis II within it; The version that two cover radial ball bearings are respectively arranged in roller I and the roller II; The stainless steel seamless pipe that in the process of bending, can make roller I and roller II be close to φ 25 * 3 is all the time done pure rolling, so operation is simple, can guarantee that the product surface that bends is smooth.
Description of drawings:
Figure: the manual swan neck system structural representation of the utility model;
1, bearing 2, stainless steel seamless pipe 3, support member I 4 support member II5, fixed axis I 6, fixed axis II 7, chassis 8, handle 9, rotating turret 10, roller I 11 roller II
The specific embodiment:
Bearing 1 is a trapezoidal shape, and a side that goes up in the above connects support member I3 through bolt, and opposite side connects chassis 7 through bolt; Middle part welding support member II 4 on chassis 7; 7 the outside flexibly connects rotating turret 9 on the chassis, and rotating turret 9 is horizontal " U " shape, at the end connection handle 8 of sealing; Portion is connected roller I 10 and roller II 11 respectively through fixed axis I 5 and fixed axis II 6 within it, and two cover radial ball bearings are respectively arranged in roller I 10 and the roller II 11.
During use, stainless steel seamless pipe 2 is passed support member I 3 and support member II 4, enter between roller I 10 and the roller II 11; And lean out, turning handle 8, rotating turret 9 is the center of circle with fixed axis II 6; Make circular motion; Roller I 10 and roller II 11 are close on the stainless steel seamless pipe of φ 25 * 3 all the time, in the process of bending, all do pure rolling, therefore can guarantee that the product surface that bends is smooth; Consider strain, bend handle 8 in the process angle of bend can >=180 °, adjustment roller I 10 and roller II 11 spacings can guarantee that the product bending radius is R42, thereby satisfy the product technology requirement, realize bending the purpose of " U type pipe ".
Claims (2)
1. manual swan neck system; Be made up of bearing (1), it is characterized in that described bearing (1) upper end one side is fixedly connected support member I (3), opposite side is fixedly connected chassis (7); The middle part on chassis (7) is fixedly connected support member II (4); Its outside flexibly connects rotating turret (9), and rotating turret (9) is horizontal " U " shape, at the end connection handle (8) of sealing; Portion is connected roller I (10) and roller II (11) respectively through fixed axis I (5) and fixed axis II (6) within it, and two cover radial ball bearings are respectively arranged in roller I (10) and the roller II (11).
