Description
Technical field
The present invention relates to the rolling of a kind of metal material and rivet welding technology, particularly a kind of rolling and rivet welding technology of flange.
Background technology
The method of existing manufacturing flange mainly contains: 1, whole plate cuts method for making (its shortcoming is a waste material); 2, casting (its shortcoming is that the difficult quality of flange is controlled); 3, forging method (its shortcoming is the manufacturing cost height); 4, the method that twists.
The existing method that twists is shown in Fig. 1 a, 1b, and its main processes is: with flat steel 1 by rolling the required intercepting certain-length of several flanges, with flat steel 1 to send in the kidney basin 3 with kidney basin 3 parallel plane directions.The spiral annulus that under the acting in conjunction of kidney basin 3 and pinch roller 2, flat steel 1 is twisted and is close to mutually between the lopping circle, then along the spiral annulus radially cut apart incision, flatten welding again and form flange.
There is following shortcoming in the existing method of twisting:
1, shuts down charging, twist otherwise the block on kidney basin 3 limits can not keep off the stub bar of flat steel 1.
2, adopted have the inclination the method for rolling and material not on one side scrolling break away from kidney basin 3 on one side, eject with the spiral annulus of push rod 4 but must shut down afterwards twine formation.
3, the number of turns that at every turn rolls is many more, and the frictional force when then material breaks away from the axle of kidney basin 3 is big more, thus once can only roll up several, thus cause that waste of material is big end to end.
4, because the spiral circle ring circle that is subjected to twisting is close to and the restriction of the current machine structure that twists, can't roll up a circle and cut once, shut down the back that can only the whole piece material twists, and the spiral annulus is taken out, and cuts apart the back welding.The whole process flow time is long, can not weld when high temperature.Because above 4 all exist long shortcoming of operating time, manufactured flange technology does not all have to dock with the in line steel rolling production-line of average per second more than 1,2 meters so existing usefulness twists.
Summary of the invention
The purpose of this invention is to provide the flange fabrication technology that a kind of speed of production is fast, stock utilization is high, production cost is low.

Above-mentioned flat steel is curled into the multi-circle spiral flow annulus, and is the step that the multi-circle spiral flow annulus is cut off:
A plurality of machines that twist are provided, the machine of twisting comprises the guide cover that is connected to each other and mechanism takes place mutually, kidney basin, gear, drawing-inroller, curved wheel, power wheel, fixedly spiral jacking block, spiral are close to wheel, radially are close to wheel, block, has the follower of scissors and active machine, follow-up motor; And provide punch press;
Described flat steel is delivered on described a plurality of machine that twists successively through distributing raceway, through the guide cover and to become 10 °～20 ° angle to be put on the machine that twists that has started with the plane of kidney basin, gear has caused the drive kidney basin, drawing-inroller, curved wheel, the rotation of power wheel, under the acting in conjunction of kidney basin and curved wheel with the bending of described flat steel, at fixing spiral jacking block, spiral is close to wheel, the material limit crimping that radially is close under the acting in conjunction of wheel the flat steel ejects kidney basin, and twist into the spiral annulus of helical pitch greater than the material thickness several times, when running into block, material starts follow-up motor, driven gear is with the rotational speed identical with kidney basin, and the drift that triggers punch press moves downward, thereby makes next the circle spiral annulus of scissor cut on the follower.
The invention has the advantages that: speed of production is fast, stock utilization is high, production cost is low.
Below in conjunction with accompanying drawing, describe the present invention in detail by preferred embodiment.

The specific embodiment
With reference now to accompanying drawing, present invention is described.
The present invention discloses the flange fabrication technology that a kind of speed of production is fast, stock utilization is high, production cost is low.Concrete technological process is as follows:
1, heating---140 or 120 continuous casting square billets that will be about 3 meters are heated to rolling temperature in heating furnace.
2. rolling---with many milling trains above-mentioned continuous casting square billet tandem rolling is become the flat steel.
3. twist---shown in Fig. 2 a-2c, above-mentioned flat steel 1 is delivered on 6～10 machines that twist successively through distributing raceway, become 10 °～20 ° angle to be put into the machine that twists that has started through guide cover 18 and with the plane with kidney basin 5, power drives the rotation of kidney basin 5, drawing-inroller 17, curved wheel 6, power wheel 14 through gear 12.The commentaries on classics scooter of kidney basin 5
More than 9 rev/mins.Under the acting in conjunction of kidney basin 5 and curved wheel 6 with the bending of flat steel.The material limit crimping that be close to wheel 16 at fixedly spiral jacking block 11, spiral, radially is close under the acting in conjunction of wheel 15 with flat steel 1 ejects kidney basin 5, and twists into the spiral annulus of helical pitch greater than the material thickness several times.When running into block 8, material starts stepper motor, driven gear 19 is with the rotational speed identical with kidney basin 5, and the drift 9 that triggers punch press moves downward, and encloses spiral annulus thereby make scissors 7 on the follower (screw rod 13 on the follower and the helical pitch of spiral pieces 10 are identical with the helical pitch of fixing spiral jacking block 11) shear next.
4. flattening---the spiral annulus that forms after the above-mentioned shearing flattens on feed mechanism pushing inlet pressure machine.
5. welding---the annulus after will flattening is delivered to welding automatically on the flash butt welder through feed mechanism.
The main points of this technology are to have improved the structure of the existing machine that twists.
1, made the block on kidney basin 3 limits of generally using on the existing machine that twists into baffle ring, shown in Fig. 2 a-2c, thereby can before charging, open the machine that twists earlier with the cancellation charge time.
2, shown in Fig. 2 a-2c, top, the plane of kidney basin 5 increases fixedly spiral jacking block 11, and the limit crimping pushes up material from kidney basin 5, thereby the spiral annulus of helical pitch greater than the material thickness several times that twist out.Because above improvement, make that limit volume, limit are cut, limit high temperature butt welding and dock with steel rolling production-line and to be able to smooth realization at 2.
The quantity of the used machine that twists is according to the size of the flange inner and outer diameter that is bent and fixed in this technology, such as bending external diameter 400, it is 12 rev/mins the machine that twists that the flange of internal diameter 210 can be selected 8 speed of rolling for use, then per minute is produced 96 flanges, per minute needs about 92 meters of consumptive material, just docks with the rolling line that average mill speed is about 90 meters of per minutes.
The type specification of common apparatus such as the punch press that this technology is mentioned, forcing press, flash butt welder can suitably be chosen according to the sectional area size of the flange that twists.
The most suitable production lot of this technology is big, to surface size and the less demanding flange of fineness, such as the prestressed concrete pipe pile flange.
Above disclosed only is the preferred embodiments of the present invention, can not limit the present invention's interest field certainly with this, and therefore the equivalent variations of being done according to the present patent application claim still belongs to the scope that the present invention is contained.
