Further, the roller bearing of described composition roller bearing chain is identical with the structure that compresses roller bearing, roller bearing is comprised of contiguous block, otic placode, axle, cylinder and locking plate, contiguous block is installed in the upper end of axle, otic placode is installed in the both sides of contiguous block, and drum sleeve is on axle, and the hypomere of locking plate and axle adopts thread connecting mode to fix, form after otic placode between the roller bearing of roller bearing chain docks mutually and connected by bolted, and in the face that is in contact with one another of the otic placode slip teeth of setting up defences; Described rotating beam is comprised of upper and lower beam and tie-beam, and the slotted hole that upper and lower beam is strip is dull and stereotyped, and upper and lower beam is horizontally fixed on respectively the upper and lower end of tie-beam, and upper and lower beam is all hinged with described fixed axis, and described hook is fixed on tie-beam; The first roller bearing of described roller bearing chain is arranged between described upper and lower beam, its axle is through the slotted eye of upper and lower beam, the contiguous block frame of axle upper end is at upper beam upper surface, axle hypomere stretches out from the slotted eye of underbeam, cylinder on axle is between upper and lower beam, after the locking plate of axle hypomere screws, be pressed in underbeam lower surface, locking plate coordinates with contiguous block is fixed on rotating beam this roller bearing; Described compression roller bearing adopts the be connected and fixed mode identical with the first roller bearing of above-mentioned roller bearing chain to be fixed on rotating beam; Described hold-down support is comprised of pedestal and pipe fitting stationary fixture, and described workbench is provided with a plurality of mounting hole site, and pedestal adopts dismountable connector to be fixed in mounting hole site.
Further, the cylinder of described roller bearing is square tube grooved drum or round steel grooved drum.
Further, the first roller bearing of described roller bearing chain and the cylinder compressing on roller bearing are square tube grooved drum or round steel grooved drum, and the cylinder on all the other roller bearings is the cylinder of trough of belt not.
The beneficial effects of the utility model are analyzed as follows:
(1) each member function: workbench, is mainly each member mounting plane is provided; Rotating beam: be mainly used in as treating that elbow member provides bending moment arm; Hook, is mainly used in conveniently applying external force, as: the pulling force that overhead traveling crane, hoist engine etc. provides; Roller bearing chain, is mainly used in clamping pipe fitting, fixed bending tube radius, safeguards bending radius, and specifically first roller bearing coordinates clamping pipe fitting with compression roller bearing, and all the other roller bearings form tail chains for fixing and safeguard bending radius; Compress roller bearing, be mainly used in coordinating with the first roller bearing of roller bearing chain clamping pipe fitting; Hold-down support, is mainly used in fixedly one end of straight pipe, and crooked reaction force is provided.
(2) advantage explanation: 1. bending radius is adjustable, owing to having adopted the first roller bearing of roller bearing chain, compress the adjustable connected mode in position between roller bearing and rotating beam, the connected mode that has adopted the bolt between a plurality of roller bearings to be mutually fastenedly connected, and the adjustable connected mode in position between hold-down support and workbench, can adjust according to actual needs in use each roller bearing to the distance of fixed axis, can mix up in advance bending radius, finally again hold-down support being adjusted to appropriate location fixes, preferably after straight pipe packs into, make straight pipe perpendicular to the position of rotating beam, holder is straight pipe one end fixedly, now hook is applied to pulling force and just straight pipe can be curved to the arc tube that has preset bending radius.2. simple in structure, economical and practical, easy operating.Workbench, roller bearing, rotating beam, hold-down support are all on-the-spot conventional mechanical components, and structure is all fairly simple, through reasonably processing assembling, just can carry out bend pipe operation, and convenient disassembly is safeguarded simple and easyly, has very high practicality.
In sum, a kind of adjustable bending bilge radius formula Simple pipe bender of the present utility model, compared with prior art, it is simple in structure, economical and practical, can regulate easily setting bending radius, is adapted at some and does not take bend pipe operation and promote the use of in main enterprise.
