Description

Steel plate roll inner protective angle ring moulding machine

Roll of steel plate inner protective corner circle make-up machine; be used for crooked rectangular band steel,, be used for the protection on circle steel plate limit in the roll of steel plate by two conglobate inner protective corner circles of the cold roller and deformed bending of roll about the make-up machine; be applicable to that cold-rolled steel sheet factory makes the machinery of inner protective corner circle, belongs to package packing machine.

In the prior art, the equipment of production roll of steel plate inner protective corner circle has varied, and the existing inner protective corner circle make-up machine of producing with external certain factory is an example:

Guard ring make-up machine front view in the accompanying drawing 1

Accompanying drawing 2 inner protective corner circle make-up machine side views

The raw material schematic diagram of accompanying drawing 3 inner protective corner circles

The schematic diagram of accompanying drawing 4 inner protective corner circles

1～4 describe in conjunction with the accompanying drawings.

Bottom roll 1, topping roll 2, end plate 3, bearing spider 4, bearing 5, adjustable screw mandrel 6, power transmission shaft 7, memorial archway 8, sprocket wheel 9, motor 10, base plate 11, chain 12 cogs 13, the inner protective corner circle make-up machine that master gear 14 is formed.

2,1 of top and bottom rolls is delivered on the raw material width b limit of inner protective corner circle, adjusting screw mandrel 6 is transferred to the top and bottom rolls gap is trapezoidal suitable drafts, then width b limit is rolled, making width edge be rolled distortion prolongs, because width edge root and outer portion drafts are different, outer portion deflection is big, make raw material to height h spring song, the height limit collides on the bearing 5 after bringing out roll before the raw material, more impel the bending on height limit, after the length L of raw material is passed through top and bottom rolls fully, then roll out the inner protective corner circle of diameter D as shown in Figure 4.

The major defect of this inner protective corner circle make-up machine has:

1, run into bearing 5 after raw material is shut out by top and bottom rolls, the resistance of bearing only acts on the outside, height h limit of suitable circle, makes the height of inner protective corner circle and the junction on width b limit tear easily;

2, not axially raw material not being retrained of top and bottom rolls 2,1, raw material produces crooked and shuts out and runs into bearing 5 when rolling deformation, and after bearing applied power to raw material, the easy displacement of raw material caused the inner protective corner circle round;

3, raw thickness only is 0.8～1 millimeter, and inner protective corner circle intensity and rigidity are not enough, surpasses 1 millimeter and just can't roll out qualified inner protective corner circle.

The purpose of this utility model is at the shortcoming of above-mentioned inner protective corner circle make-up machine, has improved device structure, adopts special-shaped roll forming, sets up wheel holding mechanism and guide plate mechanism and can solve above-mentioned shortcoming.

In order to achieve the above object, the utility model takes some measures in design.

By cogging master gear, final drive shaft, adjusting screw(rod), locking nut, upper end connecting plate, memorial archway, slide block, power transmission shaft, sprocket wheel, block bearing, base plate, side plate, lower shoe, minor sprocket, the structure that original papers such as the reductor of translator and top and bottom rolls are assembled into, similar with known inner protective corner circle make-up machine.

Improve and the following mechanism of increase:

Bottom roll root car has width to be 10～20 millimeters and to protrude 4～10 millimeters boss, the topping roll car has corresponding grooves, 10～20 millimeters of groove widths and recessed 5.5～11.5 millimeters groove, boss and groove are the gap that is slidingly matched, the topping roll working face has the oblique tip of 1:100 from root to end, working face has also rolled thick straight decorative pattern, is 0.5～1 millimeter by the concave part degree of depth.

It is that 28～58 millimeters and width are 2.5～5 millimeters work nest that guide plate is milled with the degree of depth by rolled piece direction of advance right side, and guide plate mills semicircle in the roll line rear section, and its diameter is 290～640 millimeters of φ.Guide plate is contained in the front and back side between the top and bottom rolls, make the center line of guide plate work nest consistent basically with roll line, on the guide plate of roll rear side, be equipped with and roll cambered axle and hold support, be equipped with on the support and roll cambered axle and hold, the rolling guide effect is played on the height limit of inner protective corner circle.

On bottom roll right-hand member and bottom roll same axis, conical bevel gear is housed.

The supporting-roller shaft lower end is screwed on base plate, make this shaft centre line and two roll center transmission shaft lines on a vertical plane, portion's brasses is loaded on axle top earlier, refill conical bevel gear with support roller and be screwed and be in the same place, the support roller diameter is 290～640 millimeters of φ, load onto portion's brasses and fixing tight then from the axle top, the bevel gear of this bevel gear and bottom roll right-hand member is matched, so just be assembled into a new type of steel plate volume inner protective corner circle make-up machine with screw and pressing plate.

Roll of steel plate inner protective corner circle shaping machine structure novelty of the present utility model, stable operation, convenience, it is wide that product yield is big, quality reaches size range well, can use raw material width b30～60 millimeters, height h80～120 millimeter, 0.8～3 millimeter of thickness, length L is (π D+80～300) millimeter, can produce 300～650 millimeters of inner protective corner loop diameter D φ, so it is product rigidity and intensity are big, applied widely.The utility model is suitable for cold-rolled steel sheet factory, is particularly suitable for the use of large-scale cold rolling steel plate factory.

The structure of accompanying drawing 1～4 is a bottom roll 1, topping roll 2, and end plate 3, bearing spider 4, bearing 5, adjustable screw mandrel 6, power transmission shaft 7, memorial archway 8, sprocket wheel 9, motor 10, base plate 11, chain 12 cogs 13, the inner protective corner make-up machine that master gear 14 is formed.

Motor 10 rotates and drives sprocket wheels 9 by chain 12 and rotate, and the master gear 14 in sprocket wheel same axis left side rotates, and master gear 13 is engaged with cogging, so power transmission shaft 7 also rotates, topping roll 2 and bottom roll 1 all follow power transmission shaft to rotate simultaneously like this.
