Automatic welding repair machine structure is set in straight tube, and the torch head of automatic welding repair machine structure is connected to straight tube inner wall, can move axially in straight tube along pipe, separately directly be externally provided with drive roll and driven roller, drive roll is driven by motor, and straight tube can roll under predetermined speed. There are also cooling body and extraction sectors outside straight tube. After straight tube inner wall completes NI-CR-MO alloys hardened layer, straight tube is moved into pipe fitting bending mechanism and is bent, straight tube is made to be converted into scheduled camber.
Description
The present invention relates to conveyance conduit soldering and manufacture method thereof, particularly the conveying steel pipe and the manufacture method thereof of alloy hardened layer such as inner-walls of duct soldering nickel chromium triangle molybdenum also relate to manufacturing equipment.
Utilize the situation of steel pipe conveying articles very general at present, when things such as for example general cement are transported to unloading apron such as harbour, need to deliver to warehouse etc. and store the field through a conveying steel pipe.As shown in Figure 1, general several sections straight tubes and the bend pipe 11,12,13,15 prepared, connect into the conveying steel pipe 1 of suitable length again according to terrain and its features, be provided with strong suction apparatus 14 at the other end of conveying steel pipe, like this can be smoothly and apace goods is delivered to storing field storage or packing.But this common delivery pipe has following shortcoming when implementing:
Because the relation of terrain and its features, the part paragraph of conveying steel pipe 1 need have suitable bend pipe to connect, yet goods through application of force aspirator 14 with high speed high-speed mobile, in this high speed course of conveying, if conveying steel pipe 1 still can transport smoothly for straight tube, if when running into bending tube portion 15, often the goods inwall that at first impacts bending tube portion 15 in moving process moves again, so the inwall of bending tube portion 15 inner wall surface occurs and weares and teares because of often being subjected to impacting, even situation such as fracture, shown in Figure 1B, greatly reduced the working life of conveying steel pipe 1.For the intensity and the life-span of the bent tube section that improves conveying steel pipe, once considered to adopt the manufacturing of high-strength wear-resistant alloy steel pipe, but cost is quite high, does not meet economic requirement; Another method is then pasted pottery or high-strength abrasion-proof steel plate at the inwall of bent tube section, though pottery or high-strength abrasion-proof steel plate performance are good, but very inconvenient when in the pipe of about 300～450mm diameter, carrying out sticking operation, there is the difficulty in the enforcement.
The object of the present invention is to provide a kind of stiff dough soldering conveying steel pipe and manufacture method and equipment,, strengthen the impact strength of elbow internal wall at the abrasion resistance alloy hardened layers such as elbow internal wall welding nickel chromium triangle molybdenum of conveying steel pipe.
Another object of the present invention is: at abrasion resistance alloy hardened layers such as one or more layers nickel chromium triangle molybdenums of conveying steel pipe straight tube inwall soldering, can increase the working life of whole conveying steel pipe.
A further object of the present invention is: equipment such as a kind of automatic soldering mechanism and pipe bending mechanism are provided.
Technological scheme of the present invention is: be welded with abrasion resistance alloy hardened layers such as nickel chromium triangle molybdenum at conveying steel pipe straight tube and elbow internal wall, to increase the impact strength of steel pipe inwall.The manufacture method of stiff dough soldering conveying steel pipe of the present invention; Be that automatic soldering mechanism is set in the straight tube of steel pipe, automatically the torch head of soldering mechanism is connected to the straight tube inwall, can be in straight tube along tubular axis to moving, straight tube is simultaneously by the drive roll of peripheral hardware and driven cylinder, drive to roll, welding gun under scolder supplier feed to the steel pipe inwall with alloy hardened layers such as built-up welding mode soldering nickel chromium triangle molybdenums; Finish alloy hardened layers such as soldering nickel chromium triangle molybdenum at the straight tube inwall after, by the pipe fitting bending mechanism straight tube is bent, straight tube is fixed on an end of fixed mechanism, high frequency heating and fixed mechanism are positioned at the kink of straight tube, the embedding of bending force application mechanism is clipped in the kink of straight tube, by oil pressure control force application mechanism is moved to an end, after the contraction straight tube is bent into predetermined camber.
Manufacture method according to above-mentioned stiff dough soldering conveying steel pipe, the automatic soldering mechanism that is provided with in the straight tube can be done a change, automatically soldering mechanism can be packed in welding gun and scolder supplier on the tooth bar guide rail, rolling bearing and motor are located at the outside of straight tube, rolling bearing and the engagement of tooth bar guide rail, therefore after rotating through the motor driven rolling bearing, may command tooth bar guide rail, welding gun and scolder supplier laterally move, and torch head is connected to the straight tube inwall, can finish the soldering operation of the alloy hardened layers such as nickel chromium triangle molybdenum of straight tube inner tubal wall.
Required equipment in the manufacture method of stiff dough soldering conveying steel pipe of the present invention, be characterized in that straight tube inwall at steel pipe makes automatic soldering mechanism, comprise the tooth bar guide rail, rolling bearing, motor, welding gun and scolder supplier, the two ends of tooth bar guide rail are installed on the support, there is row's shape tooth on its surface, row's shape tooth bridle joint one rolling bearing, rolling bearing is controlled by motor, make it can on the tooth bar guide rail, do laterally to roll, there is one group of roller to support that welding gun can move on the tooth bar guide rail, in addition, outside straight tube, be provided with fixing frame, welding gun and scolder supplier are housed on the fixing frame; Described scolder supplier comprises motor, and scolder is supplied with machine, scolder tensioner and one group of intermeshed gear; Straight tube outer tube wall and drive roll and driven cylinder join, and drive roll and driven outer surface of cylinder are coated with the clad of promoting friction, and drive roll is by motor driven, with the Rolling velocity of control straight tube; Also be provided with cooling liquid feed mechanism and extraction sector outside straight tube, described pipe fitting bending mechanism is made up of fixed mechanism, high frequency heating and fixed mechanism and bending force application mechanism.Advantage of the present invention is: at the abrasion resistance alloy hardened layers such as inwall welding nickel chromium triangle molybdenum of the straight tube of conveying steel pipe and bend pipe, but the impact strength of reinforced pipe inwall increase the service life, and with low cost, have very big economic benefit and social benefit.
