Abstract
The invention provides a welding backing device for a taper pipe stitching welding machine, which comprises an air cylinder, a connecting rod, a swing arm bracket and a swing arm. The air cylinder is arranged on a fixed frame of a welding mechanism; a piston rod of the air cylinder is provided with a sliding block; the fixed frame of the welding mechanism is also provided with a slideway; the sliding block on the piston rod of the air cylinder is accommodated on the slideway and is fixedly connected with the swing arm bracket; the lower end of the swing arm bracket is hinged with the swing arm; the connecting rod is arranged between the swing arm and the fixed frame of the welding mechanism; one end of the connecting rod is hinged with the swing arm, while the other end is hinged with the fixed frame of the welding mechanism; and the swing arm is hinged with a backing mechanism. When the welding backing device is used for stitching welding of taper pipes, the backing mechanism is clung to the bottom surface of a welding seam so that the welding seam is shaped well and has high mechanical property, the occurrence rate of the welding defect is greatly reduced and the problems of poor shaping quality of the back surface of the welding seam, easy weld penetration of the sheet, molten steel leakage and the like are sufficiently solved.
Description
Technical field
The present invention relates to a kind of taper pipe stitching welding machine welding backing device, belong to the steel pipe manufacture mechanical equipment technical field.
Background technology
In the prior art, generally all do not adopt welding backing on taper pipe stitching welding machine, therefore, can cause its weldquality poor, when especially welding thin plate, easily burn-through, bleed-out water cause more serious weld defect, can't guarantee for the quality of appearance of weld.Must manually carry out back chipping, repair welding after the welding, thereby significantly increase construction cost.
Summary of the invention
The objective of the invention is to overcome the deficiency that prior art exists, a kind of taper pipe stitching welding machine welding backing device is provided, the incidence that is intended to effectively reduce weld defect, the mechanical property of raising appearance of weld.
Purpose of the present invention is achieved through the following technical solutions:
The welding backing device of taper pipe stitching welding machine, characteristics are: comprise cylinder, connecting rod, swing arm support and swing arm, described cylinder is installed on the fixed mount of welding mechanism, the piston rod of cylinder is provided with slide block, also be furnished with slideway on the fixed mount of welding mechanism, slide block on the described cylinder piston rod is contained on the slideway, and the slide block on the cylinder piston rod fixedlys connected with the swing arm support, and the lower end and the swing arm of swing arm support are hinged; Between the fixed mount of swing arm and welding mechanism connecting rod is set, an end and the swing arm of described connecting rod are hinged, and the other end of connecting rod and the fixed mount of welding mechanism are hinged, and are hinged with washer mechanism in swing arm.
Further, the welding backing device of above-mentioned taper pipe stitching welding machine, wherein, described swing arm is strip structure, in the hinged washer mechanism of the front end of described strip swing arm.
Substantive distinguishing features and obvious improvement that technical solution of the present invention is outstanding are mainly reflected in:
When structure uniqueness of the present invention, this device were used for the welding of Taper Pipe joint close, washer mechanism can be close to the weld seam bottom surface, make appearance of weld attractive in appearance, mechanical property is good, greatly reduces the incidence of weld defect, it is poor fully to have solved the back of weld Forming Quality, problems such as the easy burn-through of thin plate, bleed-out water.And can change liner, flexible movements, stable performance, easy to use, low cost of manufacture according to the workpiece size; Be rated as have novelty, the good technology of creativeness, practicality.
Description of drawings
Below in conjunction with accompanying drawing technical solution of the present invention is described further:
Fig. 1: organigram of the present invention.
The implication of each Reference numeral sees the following form among the figure:
The specific embodiment
As shown in Figure 1, the welding backing device of taper pipe stitching welding machine, mainly comprise cylinder 4, connecting rod 7, swing arm support 5, swing arm 8 and washer mechanism 1, cylinder 4 is installed on the fixed mount 3 of welding mechanism, the piston rod of cylinder 4 is provided with slide block, also is furnished with slideway 6 on the fixed mount 3 of welding mechanism, and the slide block on the cylinder piston rod is contained on the slideway 6, and the slide block on the cylinder piston rod is fixedlyed connected with swing arm support 5, and the lower end of swing arm support 5 and swing arm 8 are hinged; Swing arm 8 is strip structure, between the fixed mount 3 of swing arm 8 and welding mechanism connecting rod 7 is set, and an end and the swing arm 8 of connecting rod 7 are hinged, and the other end of connecting rod 7 and the fixed mount of welding mechanism 3 are hinged, in the hinged washer mechanism 1 of the front end of strip swing arm 8.
During concrete the application, swing arm 8 is stretched in the weldment together with washer mechanism 1, and swing arm support 5, connecting rod 7 are in the middle of weld seam, and after the positive pinch roller of band junction of the edges of two sheets of paper wheel, positive pinch roller junction of the edges of two sheets of paper wheel width is slightly wider than the thickness of slab of swing arm support 5, connecting rod 7; When the both sides pinch roller compresses weldment two rear flank, make the weld seam joint close, be in state to be welded, welding gun places directly over the weld seam.When cylinder 4 work, slide block on the cylinder piston rod moves along slideway 6, ordering about swing arm support 5 by the slide block on the cylinder piston rod moves both vertically, pass through lever principle, as fulcrum, cylinder 4 presses down by connecting rod 7, and swing arm 8 is moved clockwise along bearing pin, move on the front end of strip swing arm 8, make washer mechanism 1 up and be close to the back side of weld seam.And washer mechanism 1 is hinged on the front end of strip swing arm 8, guarantees in the welding, washer mechanism 1 caters to back of weld fully, and welding backing is motionless, and move on workpiece side weld limit straight line forward, back of weld and washer mechanism 1 are made linear relative movement, thereby better realize the effect that appearance of weld is good.
Washer mechanism 1 self is cooled off by recirculated water, guarantees the possibility of long-time continuation welding, does not have other bad phenomenon.In the welding process, workpiece is made reverse rectilinear motion, and liner is close to the welding gun below, guarantees the appearance of weld quality.
In sum, modern design of the present invention is when being used for the welding of Taper Pipe joint close, washer mechanism is close to the weld seam bottom surface, makes appearance of weld attractive in appearance, and mechanical property is good, greatly reduced the incidence of weld defect, it is poor fully to have solved the back of weld Forming Quality, problems such as the easy burn-through of thin plate, bleed-out water.In addition, can change liner, flexible movements, stable performance, easy to operate, low cost of manufacture according to the workpiece size; Economic benefit and social effect are remarkable, and application prospect is very wide.
It is emphasized that: above only is preferred embodiment of the present invention, be not that the present invention is done any pro forma restriction, every foundation technical spirit of the present invention all still belongs in the scope of technical solution of the present invention any simple modification, equivalent variations and modification that above embodiment did.
