Abstract
The utility model discloses an interior longitudinal seam welding machine, including track groove (1) that can walk, solder flux pipe (2) and welding wire pipe (3) arrange along track groove (1) that just the front end of solder flux pipe (2) and welding wire pipe (3) is connected with the lower part of welding head (4) and the upper portion of welding head (4) respectively, welding wire in welding wire pipe (3) stretch out downwards welding head (4) outer and solder flux pipe (2) in the solder flux unrestrained towards the welding wire from the top of welding wire, welding head (4) are stretched into steel pipe the postposition welding wire on the longitudinal joint and solder flux in the steel pipe and are mutually supported internal longitudinal joint and weld. The utility model discloses stretch into the positive butt welded seam of steel pipe relief welding wire with the welding head, internal longitudinal joint welds under of the mutually supporting of welding wire and solder flux, and the welded steel pipe is accomplished until breaking away from to welding head stable retreating under of the pulling in track groove among the welding process, the further welded accuracy of having guaranteed that sets up of walking and taking turns has improved production efficiency and welding quality, suitable using widely.
Description
Technical field
The utility model relates to a kind of welding equipment, specifically a kind of interior longitudinal seam welding machine of time-saving and efficiency.
Background technology
The welding difficulty that in steel pipe, outer longitudinal joint is compared in the welding of longitudinal joint wants high, and the technician needing technical capability stronger just can complete, length consuming time and can not stablize welding.
Summary of the invention
The purpose of this utility model is for prior art Problems existing, provides a kind of interior longitudinal seam welding machine of time-saving and efficiency.
The purpose of this utility model solves by the following technical programs:
Longitudinal seam welding machine in a kind of, comprise the rail groove being arranged on and railcar can be walked, it is characterized in that: solder flux pipe and welding wire pipe to be arranged and solder flux pipe is connected with the top of welding head with the bottom of welding head respectively with the front end of welding wire pipe along rail groove, welding wire in welding wire pipe stretches out the outer and solder flux in solder flux pipe of welding head downwards and trickles down towards welding wire from the top of welding wire, and welding head is positioned at welding wire on steel pipe longitudinal joint and the solder flux internal longitudinal joint that cooperatively interacts and welds after stretching into steel pipe.
The front bottom end of described rail groove is provided with the road wheel be fixed on rail groove, on the interior longitudinal joint that road wheel falls within steel pipe and welding time along interior longitudinal joint towards retrogressing.
Described road wheel is fixedly connected with rail groove by the support be welded on rail groove.
The lower front of described rail groove is provided with backing roll, advances under the driving of rail groove railcar in its back-end on backing roll.
The top of described welding head is provided with heat extraction hole to accelerate radiating rate when welding.
The utility model has the following advantages compared to existing technology:
The utility model is by stretching into the positive butt welded seam of steel pipe relief welding wire by welding head, under the cooperatively interacting of welding wire and solder flux, internal longitudinal joint welds, and in welding process, welding head is stable under the dragging of rail groove retreats until depart from the steel pipe having completed welding; The setting of road wheel further ensures the accuracy of welding in addition; This bonding machine structure is simple, application is convenient, greatly improves production efficiency and welding quality, is suitable for promoting the use of.
Accompanying drawing explanation
Accompanying drawing 1 is interior longitudinal seam welding machine structural representation of the present utility model.
Wherein: 1-rail groove; 2-solder flux pipe; 3-welding wire pipe; 4-welding head; 5-road wheel; 6-support; 7-backing roll; 8-heat extraction hole.
Detailed description of the invention
Below in conjunction with accompanying drawing and embodiment, the utility model is further described.
As shown in Figure 1: longitudinal seam welding machine in a kind of, comprise the rail groove 1 being arranged on and railcar can be walked, the lower front of rail groove 1 is provided with backing roll 7, advance on backing roll 7 under the driving of rail groove 1 railcar in its back-end, the road wheel 5 be fixed on rail groove 1 is provided with in addition in the front bottom end of rail groove 1, road wheel 5 is fixedly connected with rail groove 1 by the support 6 be welded on rail groove 1, on the interior longitudinal joint that road wheel 5 falls within steel pipe and welding time along interior longitudinal joint towards retrogressing.The solder flux pipe 2 of this interior longitudinal seam welding machine and welding wire pipe 3 to be arranged and solder flux pipe 2 is connected with the top of welding head 4 with the bottom of welding head 4 respectively with the front end of welding wire pipe 3 along rail groove 1, welding wire in welding wire pipe 3 stretches out the outer and solder flux in solder flux pipe 2 of welding head 4 downwards and trickles down towards welding wire from the top of welding wire, and welding head 4 is positioned at welding wire on steel pipe longitudinal joint and the solder flux internal longitudinal joint that cooperatively interacts and welds after stretching into steel pipe.Heat extraction hole 8 is provided with in addition to accelerate radiating rate when welding at the top of welding head 4.
When interior longitudinal seam welding machine of the present utility model uses, first rail groove 1 is sent in steel pipe to be welded, make road wheel 5 along weld seam walking and allow the positive butt welded seam of welding wire stretching out welding head 4, start bonding machine, welding wire and solder flux interact and start welding, in welding process road wheel 5 along interior longitudinal joint towards progressively falling back until depart from the steel pipe completing welding.
The utility model is by stretching into the positive butt welded seam of steel pipe relief welding wire by welding head, under the cooperatively interacting of welding wire and solder flux, internal longitudinal joint welds, and in welding process, welding head is stable under the dragging of rail groove retreats until depart from the steel pipe having completed welding; The setting of road wheel further ensures the accuracy of welding in addition; This bonding machine structure is simple, application is convenient, greatly improves production efficiency and welding quality, is suitable for promoting the use of.
Above embodiment is only and technological thought of the present utility model is described, protection domain of the present utility model can not be limited with this, every technological thought according to the utility model proposes, any change that technical scheme basis is done, all falls within the utility model protection domain; The technology that the utility model does not relate to all is realized by prior art.
