Abstract
The present invention relates to a device for producing special-shaped steel pipes. The device has the basic structure that a direct current motor 1 drives multiple pairs of forming rollers 3 through a speed changing mechanism 2. In order to increase production efficiency, a drawing device 6 can added to the front of each of the forming rollers 3, and a squeezing and pushing device can be added to the back of each of the forming rollers 3; in order to increase production efficiency and ensure quality, an electronic computer is added to control the whole production process. The device for producing special-shaped steel pipes, which mainly uses the modes of rolling and squeezing, can be used for manufacturing special-shaped steel pipes in various shapes, the quality of the special-shaped steel pipes satisfies requirements, and the energy consumption and the cost of the device are obviously lower than those of a welding method and a cool drawing method.
Description
The present invention relates to a kind of steel tubes pressurizing unit.
The production method of existing steel tubes has two kinds, a kind of is welding, but vertical roller and horizontal roller center line be not in same vertical plane, and the structure of its every sleeve forming roller is made of a pair of vertical roller and a pair of horizontal roller, and producing steel pipe in this way is to carry out on bonding machine, continuity of production process is strong, the speed height, but produce line length, processing performance is bad, be difficult to eliminate fully welding gravitation, and just powerless to complex-shaped kind.Second kind is cold-drawing process, promptly by drawbench traction pipe, makes pipe produce plastic deformation in special-shaped fixed die and obtains the special-shaped section steel pipe.The equipment of this draw method is simple, can just can obtain the product of corresponding section by the mould of changing different passes, relatively flexibly, but mould and intermetallic are sliding friction, make cold-drawn power very big, and energy consumption is many, the easy plucking of product surface, die wear is fast, and the life-span is low and influence dimensional accuracy, workpiece sclerosis because finished surface becomes, through 2-3 cold-drawn, must carry out annealing in process, increased annealing device and corresponding energy consumption, also, need through annealing, pickling before pulling out, take the lead owing to taking the lead draw; Want crop to truncate during scale, excise approximately about 5%, influenced lumber recovery.
The purpose of this invention is to provide a kind of good product quality, the production efficiency height, wide in variety, the device of the multistage special steel tubes rolling and extruding that energy consumption is low.
The present invention as shown in Figure 1,, driven many sleeve formings roller 3 and rotate through gear 2 by dc motor 1, every suit format roll 3 as shown in Figure 2, be fixed on the framework by a pair of vertical roller 8 and a pair of horizontal roller 9 and constitute, its roller center line is all in same vertical plane.In order to improve edging speed, be added with a squeeze device at format roll 3 rear portions, squeeze device is made of oil cylinder 4 and crowded push-plate 5, its production process is as follows: connect the dc motor 1 of power supply, and slack-off through gear 2 rotating speeds, drive many sleeve formings roller 3 and rotate simultaneously, work piece is sent in the hole of format roll, work piece just can move horizontally forward with the velocity of rotation of format roll 3, and through too much format roll 3, last edging goes out needed steel tubes.In order to raise the efficiency, the oil cylinder 4 and the dc motor 1 of squeeze device start simultaneously, pushing away workpiece by crowded push-plate 5 goes ahead, for satisfying the needs of society to the different shape steel pipe, the vertical roller 8 of format roll 3 and horizontal roller 9 can be made corresponding format roll according to actual needs, as spare part, to press product requirement transposing format roll 3.
For further improving edging speed, be added with a draw-off gear 6 in the front portion of format roll 3, this draw-off gear 6 is identical with common drawing apparatus, also can not add squeeze device, only adds draw-off gear 6.
In order to control whole process of production, improve the quality of products, more than several assembling modes all can add an automaton, it mainly is made up of an electronic computer and executive component mechanism.
Advantage of the present invention is tangible, the edging method replaces welding and cold-drawing process to produce steel tubes, overcome connection and be difficult to eliminate fully weld seam gravitation, shape steel tube and the cold-drawing process that can't produce complicated shape are difficult to ensure the quality of products, annealing in process process complexity, the disadvantage that energy consumption is high, this production method is easily ensured the quality of products, the production efficiency height, and can be according to actual needs, adjust the shape of forming rolls, can produce various steel tubes.Add with electronics computer control whole process of production, product quality and production efficiency are improved, had more reliably to guarantee.
Because the every sleeve forming roller of the present invention is owing to constitute vertical roller and a pair of horizontal roller, its roller center line is all in same vertical plane, so this structure can obtain better technological requirement.
Fig. 1 is a structure drawing of device of the present invention.
Fig. 2 is the structure chart of format roll 3.
A kind of embodiment of the present invention passes through three-stage speed change mechanism 2 by 40 kilowatts dc motor 1, driving eight grades of format rolls 3 rotates, there are a squeeze device and front portion to be added with an Automatic Control Component at eight grades of format roll 3 rear portions, squeeze device is made of oil cylinder 4 and crowded push-plate 5, and Automatic Control Component is made of a director city 386 electronic computers and executing agency.Vertical roller 8 diameters of format roll 3 are at the 70-85 millimeter, horizontal roller 9 diameters are the 50-65 millimeter, this device is through 40 * 30 millimeters of edgings, 55 * 56 millimeters square type pipe, 38 * 38 millimeters, 40 * 40 millimeters, 45 * 45 millimeters, 50 * 50 millimeters square pipe and minor axis are that 40 millimeters, major axis are 50 millimeters ellipse pipe, all can satisfy actual needs.
