Description
Technical field
The utility model relates to steel pipe technical field of processing equipment, is specifically related to coating heating unit in a kind of weldless steel tube.
Background technology
Weldless steel tube is that one has hollow section, periphery does not have jointed circle, square, rectangle steel.Weldless steel tube is to make hollow billet with steel ingot or the solid pipe hole that wears long, and then makes through hot rolling, cold rolling or cold group.Be widely used in manufacturing structure part and mechanical component, as steel scaffolding of using in oil drill rocker, truck drive shaft, bicycle frame and building operation etc., along with the development of steel industry, the weldless steel tube of Steel Tube Industry has been subject to a lot of attention, increasing enterprise applies to weldless steel tube, and weldless steel tube industry has been subject to a lot of people's favor.Conventional plastic machinery the volume seamless steel pipe internal wall wear resisting property that uses bad, can not meet the requirement that works long hours, therefore need wall therein to plate one deck wearing layer.
Utility model content
It is a kind of simple in structure that technical problem to be solved in the utility model is to provide, coating heating unit in the weldless steel tube of homogeneous heating.
Technical problem to be solved in the utility model realizes by the following technical solutions:
Coating heating unit in a kind of weldless steel tube, comprise a heating furnace body, this heating furnace body inside has a heated chamber, described heated chamber one end is opening for feed, the other end is discharge port, be equipped with a support in described opening for feed outside and discharge port skin, described heated chamber inner bottom surface is provided with two live rolls, described live roll two ends are overlapped on support by bearing assembly respectively, the live roll that is wherein positioned at opening for feed one end is connected with motor by gear and chain, rotate through chain and gear driven live roll by motor, making to be positioned at steel pipe on live roll can uniform rotation, make homogeneous heating.
Described two live rolls be arranged in parallel, between two live rolls, are provided with spacing, and steel pipe to be heated is put between two live rolls.
Described opening for feed and discharge port place are all provided with hermatic door, and sealing door is closed in the time that body of heater heats, and guarantee that body of heater inside reaches certain temperature.
On described support, between two live rolls, be arranged with two circular arc strut members.
The beneficial effects of the utility model are: the utility model is simple in structure, reasonable in design, can guarantee that steel pipe is heated evenly in heat-processed, improve the quality of products.
