Abstract

The utility model relates to a dual-roller obliquity continuous casting and rolling machine, belonging to an exclusive use production device of plate-strip blank of deforming aluminum and aluminum alloy. The utility model mainly comprises a continuous casting and rolling machine 8, a tractor 10, swing-typed shears 11, and a reeling machine 12. The dual-roll obliquity continuous casting and rolling machine adopts side casting way that the dual-roller obliquity type main frame retroverts 15 DEG; in this way, the area of casting and rolling is enlarged; the speed of casting rolling increases 40 per cent-50 per cent; the utility model can produce alloys and blunt aluminum of aluminum manganese and aluminum magnesium series. The roller gap is controlled by a roller gap adjusting screw rod 13 and a roller gap adjusting sloping block 17, and is pre-stressed and butted tightly by a main pressing upper oil cylinder 20; a stable plate thickness is obtained, and the roller gap is adjusted conveniently and reliably.

Description

Dual-roll obliquity continuous casting and rolling machine

The utility model relates to a kind of pair of roller tilting casting and rolling machine row, belong to the production equipment special of distortion aluminium and aluminum alloy strip blank.

The production technology of distortion aluminium and aluminium alloy plate carries product has two kinds, and a kind of is ingot casting hot rolling method, and another kind is a casting and roll process.Though it is longer that ingot casting hot rolling method production technology development early, has the production cycle, the cost height, the production equipment one-time investment is big wait not enough.Characteristics such as casting and roll process has with short production cycle, and cost is lower, and the production equipment one-time investment is little.But the casting and roll process that adopts adopts bottom pouring type to see Fig. 1 because the running gate system 2 of casting and rolling machine 1 is vertical with horizontal plane at present, and slab 46 curves 90 ° and batches, and its casting and rolling machine lists intention and sees Fig. 1.This version is not only operated inconvenience, and can not directly apply tension force to the slab in the roll gap 46, needs to set up tension force with five-roll machine 5 and coiling machine 6 and guarantees that rolling is neat.Slab 46 easily with roll take place bonding, in case the discovery roll banding has only the reduction roll casting speed.Could solve.The casting section length of bottom pouring type is subjected to strict restriction, and the alloy kind of being cast can only the blunt aluminium of casting industry, can not casting-rolling aluminum alloy.

At the deficiencies in the prior art, the purpose of this utility model provides a kind of pair of roller tilting casting and rolling machine row.

The utility model mainly is made up of casting and rolling machine 8, hauling machine 10, rocking shears 11, coiling machine 12.(see figure 2).

The utlity model has following characteristics.

1, casting and rolling machine 8(sees Fig. 3) mainframe 24 back rake angle α be 15 °, take side formula running gate system, reduced the static pressure of liquid metal, increased casting district roll casting speed and improved 40～50% and not only can produce blunt aluminium and also can produce aluminium manganese, the alloy of magnalium series.

2, the main frame memorial archway adopts entablature pin locking open-type, promptly is made up of mainframe 24 milling train loam cakes 16 and frame pull bar 25.During roll change, remove milling train loam cake 16, can save common roll-changing equipment directly with crane loading and unloading topping roll 26 bottom rolls 42.

3, roll gap is adjusted leading screw 13 roll gap by roll gap and is adjusted skewback 17 controls, presses oil cylinder 20 by the master again and should hold out against in advance, can obtain stable thickness of slab like this, and roll gap is easy to adjust reliable.

4, a guide roller 9 is set on the outlet mainframe 24 of casting and rolling machine 8, slab 46 comes out to transfer level to through guide roller 9 from 15 ° of directions, and coiling machine 12 can be set up tension force with slab 46 like this, saves the five-roll machine of bottom pouring type.(seeing Fig. 1, Fig. 2).

Therefore, the utlity model has tangible good effect and remarkable economic efficiency.

Casting and rolling machine 8(of the present utility model sees Fig. 3) be to constitute like this.Two U-shaped mainframes 24 are housed on base 27, the main bottom roll 42 that tape spool bearing 41 is equipped with in 24 the inside that presses above the

oil cylinder

20,20 is housed on 24.Below the bearing block 44 at topping roll 26 two ends two inclined-planes are arranged, between 41 and 44 two ends, respectively have a roll gap to adjust leading screw 13 and two roll gap adjustment skewbacks 17.There are the two ends of a guide roller 21,21 respectively to have an oil cylinder 22 to be fixed on 24 in the side of mainframe 24.Guide roller 21 is the guide roller 9 among Fig. 2.The top of mainframe 24 is milling train loam cakes 16, with pin 14 they is joined together.The angle α of the center line of mainframe 24 and vertical line is 15 °.Can regulate the height of guide roller 21 with oil cylinder 22.。

Rocking shears 11(of the present utility model sees Fig. 4, Fig. 5) be to constitute like this.Two rotating shafts 32 are housed on fixed mount 43, all are equipped with in each rotating shaft 32 oil cylinder 33 is housed on the

guide pillar

34,34, by sill 45 two oil cylinders 33 are joined together, on the top of guide pillar 34 entablature 28 is housed, the top is fixing by locking nut nail 36.Shear knife 29 pressing plates 30 are being housed on the entablature 28.There is an oil cylinder 40 at the middle part that down cut

cutter

31,45 is housed on sill 45.

Below in conjunction with accompanying drawing exemplary embodiments of the present utility model is set forth.

Casting and rolling machine 8(sees Fig. 3) the angle α of mainframe 24 and vertical line be 15 °, material mouth 7 adopts sides to annotate formulas.Before the casting, adjusting leading screw 13 according to the needs of processing by the rotation roll gap makes roll gap adjustment skewback 17 move along the inclined-plane of bearing block, because 13 screw thread divides two sections of positive left-hand threads, also be respectively positive left-hand thread for two 17, like this when ROT13 because the rotation direction difference, two roll gap are adjusted that skewback 17 can shift near and separately are that roll gap strengthens and reduces.After aluminium water entered roll by running gate system 7, when topping roll 26 and bottom roll 42 rotated along direction shown in Fig. 3 arrow, slab 46 promptly shut out through guide roller 21 along the arrow direction.Oil cylinder 33 is lifting axe bearing 41 all the time, is slightly larger than the self-locking angle because roll gap is adjusted the inclined-plane gradient of skewback 17, and its component of adjusting leading screw 13 axis directions along roll gap is increased, so promptly be convenient to bearing block centering make again two 17 stressed evenly.

Rocking shears 11(sees Fig. 4, Fig. 5) down cut cutter 31 be to cut, usually the slab 46 after the casting between the last shear knife 29 down cut cuttves 31 by (seeing shown in Fig. 5 arrow), batch (see figure 2) by coiling machine 12.(see figure 5) down cut cutter 31 is by oil cylinder 33 jack-up the time when needs are sheared, whole rocking shears 11 serves as that axle is swung synchronously toward direction shown in the arrow and slab 46 under the effect of oil cylinder 40 with rotating shaft 32, down cut cutter 31 compresses slab 46 with pressing plate 30 earlier, i.e. the sheared edge swing while compressing.Instantly shear knife 31 and last shear knife 29 are cut off slab 46 in a flash, after oil cylinder 40 will make whole rocking shears 11 swing the arrival front limit fast toward direction shown in the arrow fast, oil cylinder 40 is returned to initial position with integral body again, and 31 and 29,30 quick disengagements were finished once shearing simultaneously.

Hauling machine 10, coiling machine 12 all adopt prior art.

The structural design of topping roll 26, bottom roll 42 all adopts prior art.

The forward swing angle of swinging shears 11, the last top speed of oil cylinder 33, the speed that pushes away before the oil cylinder 40 all should be complementary with the roll casting speed of casting and rolling machine 8.

Casting section length described in the literary composition is meant the vertical range (seeing the L among Fig. 6) of top and

bottom rolls

26,42 center on lines and running gate system 7 front end faces.
