Drawings
FIG. 1 is a schematic view of the structure of the present invention;
FIG. 2 is a schematic side view of a fixing block;
in the figure, 1, a heating furnace body, 2, a heating cavity, 3, a mounting plate, 4, a driving motor, 5, a driving gear, 6, a driven gear, 7, a driving shaft, 8, a driven shaft, 9, a fixed block, 10, raw materials, 11, a supporting plate, 12, a heat-resistant bearing, 13, a feeding and discharging door, 14, a jack, 15, a spring and 16 are arc-shaped clamping plates.
Detailed Description
The utility model provides a heating furnace is used in production of seamless steel pipe, it includes heating furnace body 1 and rotating device, this internal heating chamber 2 that is equipped with of heating furnace, heating intracavity install layer board 11, a plurality of mounting holes have been seted up on the layer board, every heat-resisting bearing 12 is installed respectively to mounting hole department, and heating furnace the place ahead fixed mounting has mounting panel 3, rotating device includes driving motor 4, driving shaft 7 and a plurality of driven shaft 8, driving motor fixed mounting is on the mounting panel and the rotation of drive shaft is driven, install driving gear 5 on the driving shaft, a plurality of the driven shaft uses the driving shaft to equipartition in the driving shaft periphery as the centre of a circle, installs driven gear 6 with driving gear meshing on the driven shaft, driving shaft and a plurality of driven shaft tip fixed mounting have fixed block 9, the fixed block middle part is equipped with jack 14, and fixed mounting has three spring 15 in the jack, the end of each spring is fixedly provided with an arc-shaped clamping plate 16, and the three arc-shaped clamping plates are encircled into a circle.
Further, a feeding and discharging door 13 is hinged on the heating furnace body at the position corresponding to the heat-resistant bearing.
When the raw material 10 is sent into the heating furnace for heating, the raw material enters from the feeding and discharging door, one end of the raw material is positioned at the position of the heat-resistant bearing, the other end of the raw material penetrates into a fixing block inserting hole at the end part of the driving shaft or the driven shaft and is clamped by an arc-shaped clamping plate, then the material inlet and outlet door is closed, the motor is driven to act to drive the driving shaft to rotate, so that the raw materials on the driving shaft rotate together, meanwhile, as the driving shaft is provided with the driving gear, the driven shafts are uniformly distributed on the periphery of the driving shaft by taking the driving shaft as a circle center, the driven gears meshed with the driving gear are arranged on the driven shafts, the driving shaft can drive the driven shafts to rotate simultaneously when rotating, thereby leading the raw materials on the driven shaft to rotate together, leading the raw materials to be heated more uniformly, being beneficial to ensuring the rolling quality of the seamless steel pipe in the later period, and the structure is simpler, the operation cost is lower, and all raw materials can realize the simultaneous rotation only through a motor drive.
In conclusion, the heating furnace for producing the seamless steel tube has the advantages of simple structure, low operation cost and uniform heating of raw materials.
