Description
Technical field
The utility model relates to machining equipment, is specifically related to a kind of heading bending machine.
Background technology
Boiler and chemical industry often need be used bend pipe in the prior art, and what wherein use was many especially is coiled pipe.Coiled pipe generally all is to be made through the bending machine clod wash by straight tube, and comparatively advanced at present bending machine is generally the heading bending machine, and the heading bending machine mainly comprises: main die body, clamp mechanism, feeding pressure mechanism and top-pushing mechanism etc.Main die body can turn round, and clamp mechanism and main die body can clamp pipe fitting one end, and top-pushing mechanism can be clamped the pipe fitting other end.The course of work: clamp on the clamp mechanism and main die body clamp pipe fitting one end; Guide plate on the feeding pressure mechanism compresses pipe fitting simultaneously; Chuck on the top-pushing mechanism is clamped the pipe fitting other end, main die body revolution, and the while top-pushing mechanism is followed main die body pushing tow pipe fitting and is synchronized with the movement forward; Pipe fitting is wrapped in completion bend pipe action on the main die body along with producing flexural deformation in the main die body turning course with pipe.In this bending deformation process, fold takes place in inboard being prone to of pipe fitting, and the bend pipe latter end is prone to defectives such as bulge, is not allow these defectives to exist on the coiled pipe that in the boiler industry of China, uses.
To these defectives; Prior art generally adopts and increases wrinkle resistant plate and solve, but because the wrinkle resistant plate that uses is fixed, main die body just is close to always by wrinkle resistant wrench portion before bend pipe begins; In the whole bending deformation process of metal tube, the pipe fitting inboard is provided support, thereby play wrinkle resistant effect.But between metal tube and wrinkle resistant plate, wrinkle resistant plate and the main die body relative motion takes place all in whole BENDING PROCESS; Thereby produce friction, though fixing wrinkle resistant plate has adopted quality material and passed through heat treatment, it is still very serious to wear and tear; Generally behind hundreds of pipe fittings of bending, just need to change wrinkle resistant plate; And replacing need spend the time about half an hour at least at every turn, therefore uses fixing wrinkle resistant plate not only to increase cost, also has a strong impact on operating efficiency.So be necessary the Wrinkle-resisting unit of heading bending machine is improved.
The utility model content
To above situation; The heading bending machine that the utility model provides; Use portable wrinkle resistant apparatus for shaping, reduce the friction between the wrinkle resistant dressing stick and pipe fitting in the BENDING PROCESS, when guaranteeing bending quality, prolong the service life of wrinkle resistant dressing stick greatly; Thereby improve the operating efficiency of heading bending machine greatly, have extraordinary market prospects.
The heading bending machine that the utility model provides comprises main die body, pushing tow guide plate and top-pushing mechanism, also comprises portable wrinkle resistant apparatus for shaping.The course of work: pushing tow guide plate and main die body clamp pipe fitting one end, and the chuck on the top-pushing mechanism is clamped the pipe fitting other end simultaneously, main die body revolution; Top-pushing mechanism is followed main die body pushing tow pipe fitting and is synchronized with the movement forward, and pipe fitting stops preceding about 30 ° along with main die body revolution produces flexural deformation when being bent to bend pipe according to the angle of bend that is provided with in advance; Portable wrinkle resistant apparatus for shaping moves forward, and arrives predetermined bend pipe deformed area until the wrinkle resistant engagement positions of movable type, and this moment, portable wrinkle resistant engagement positions just in time was close to main die body; When bending, inboard the formation effectively of pipe fitting supported, guarantee not fold of pipe fitting inboard, the bend pipe latter end does not have defectives such as bulge; In this of short duration process between pipe fitting and the portable wrinkle resistant engagement positions relative motion takes place all; But because the latter end angle of bend is very little, the distance of relative motion is quite short, and therefore the wear extent of portable wrinkle resistant engagement positions is very little; Can long-time continuous use, thereby improved the service life and the operating efficiency of heading bending machine greatly.
In the preferred version of the utility model, the wrinkle resistant apparatus for shaping of above-mentioned movable type specifically comprises wrinkle resistant dressing stick, movable bearing support and guide rail, and this wrinkle resistant dressing stick is installed on the guide rail through movable bearing support.Wrinkle resistant dressing stick is the critical piece of portable wrinkle resistant apparatus for shaping, and movable bearing support and guide rail can play the effect of the stability of the accuracy of guaranteeing wrinkle resistant dressing stick position and motion.
In the preferred version of the utility model, the front side of above-mentioned wrinkle resistant dressing stick is provided with tube seat.The wrinkle resistant dressing stick that is provided with tube seat is better to the parcel property of pipe fitting, and the support to pipe fitting in the process of wrinkle resistant shaping is also more favourable, helps the effect that provides wrinkle resistant.
In the preferred version of the utility model, the rear side of above-mentioned wrinkle resistant dressing stick is the cylinder shape, and the horizontal cross-section of this cylinder is the cylinder that half-circle-arc shape is decided angle, cooperates with main die body, is used for the wrinkle resistant and shaping of pipe fitting crooked position.
In the preferred version of the utility model, the rear side of above-mentioned wrinkle resistant dressing stick is the cylinder shape.The rear side of wrinkle resistant dressing stick is arranged to cylindrical shape, is in order to cooperate the shape of main die body, when reducing wrinkle resistant dressing stick and carrying out wrinkle resistant shaping and the friction between the main die body.
In the preferred version of the utility model, also comprise the control system, this control system controls the motion of wrinkle resistant dressing stick.Stop preceding about 30 ° when pipe fitting is bent to bend pipe, the control system sends signal, impels cylinder action, and wrinkle resistant dressing stick just slowly moves forward, directly ends wrinkle resistant dressing stick head and arrives predetermined bend pipe deformed area, thereby make the action of wrinkle resistant dressing stick more accurate.
The advantage and the beneficial effect of the utility model are: use portable wrinkle resistant apparatus for shaping; In the most of the time of BENDING PROCESS, outside bending deformation area, the time of contact friction is quite short between actual pipe fitting and wrinkle resistant dressing stick, wrinkle resistant dressing stick and the main die body always for wrinkle resistant dressing stick; Wrinkle resistant dressing stick wear extent is very little; Thereby when guaranteeing bending quality, prolong the service life of equipment greatly, thereby improve the operating efficiency of heading bending machine greatly, have extraordinary market prospects.
