Abstract

The invention relates to the processing of metals by pressure and can be used for straightening sheet and strip. The purpose of the invention is to expand the technological capabilities of the machine by providing for the straightening of the curvature of the edges of the car. The leaf-straightening machine contains the upper and lower rows of cassettes (K) installed on the frame and the mechanisms of their axial fixation. Each K is made in the form of a housing 9, in the groove 10 of which the housings 11 with support rollers (P) 5 and pillows 13.14 with correct P 4 are mounted. A protrusion 15 on the pillow 14 fixes P 4 from axial displacement. Mechanisms 6 are designed for vertical adjustment K. Correct P 4 is suspended on buffer devices 16 and its cushion m. installed at different levels. Cases 9 K in one row are connected to each other and to the frame by inserts, each of which is located in the common groove of two neighboring K. With the stand, the outermost K is also connected by inserts. Such a structure ensures the transfer of the axial force of the straightening from P to the frame. 8 il.

The invention relates to the processing of metals by pressure and can be used for straightening sheet and strip.

The aim of the invention is to expand the technological capabilities of the machine by providing straightening curvature of the edges of the car.

FIG. 1 shows a leaf-leveling machine; a general view of FIG. 2 .- section A-A in FIG. 1j in FIG. 3 - section bb of fig section bb of fig section dc in fig. D-section d of fig section e-e of fig. four.

The sheeting machine contains a frame 1, in the window of which the top 2 and bottom 3 cartridges with the correct 4 support 5 rollers are installed. The upper cassettes are equipped with individual vertical displacement mechanisms 6, made in the form of pressure screws, and the lower ones are installed on the transshipment pallet 7 and are fixed on it axially by projections 8. Each cassette includes a housing 9, in the longitudinal horizontal groove 10 of which the housing 11 on porous rollers is inserted 5 with the mechanisms 12 for adjusting the support rollers in height, made in the form of two wedges moving relative to each other, and the cushion 13 and 14 of the correct roller 4, the Pillow 14 of the fixed support with The drive side (not shown) has a protrusion 15 that cooperates with a corresponding groove of the housing 9. The cassette is located perpendicular to the longitudinal groove 10. In the vertical direction, the cushions of the correct rollers are connected to the cassette housing via a buffer device 16, which is spring loaded. the end connected to the body of the cassette, and the second - with the pad of the correct roller.

The cassettes of the upper row are interconnected in a single unit with the possibility of vertical movement relative to each other by means of latches made in the form of inserts 17 fixed in the common vertical section of the slots of the bodies of the adjacent cassettes. Side working surfaces of the insert 17 are made as part

cylindrical surface. Extreme. The inserts 18, fixed on the outer surfaces of the extreme cassettes of the upper and lower rows, form a tooth, through the movable shields of the axial fixation mechanism 19, press the extreme cassettes of the upper and lower rows to the frame 1 of the machine.

The machine works as follows

The rolled steel (not shown) passes between the correct rollers 4 installed in the upper 2 and lower 3 cassettes in a staggered order relative to each other. Due to this, the straightening is carried out as a result of alternating bending of the rolled between the upper and lower regular rollers.

During the work process, straightening forces arise, which are perceived by the correct rollers 4 and transmitted through the support rollers 5, the cassettes 2, 3, the individual mechanisms for the vertical movement of the upper cassettes 6 and the pallet 7 to the frame 1.

The axial straightening force, perceived by the fixed pads 14 of the correct rollers 4 of the upper row of cassettes, is transmitted through the protrusion 15 of the pillow, which interacts with the corresponding groove in the cassette, to the body. 9 cassettes and through the insert 17, located between the housings of adjacent cassettes, on the extreme cassettes. Inserts 18 fixed to the outer surfaces of the extreme cassettes and interacting with the movable shields of the axial fixation mechanism 19 close the axial force of the Editing to the bed of the 1 straightening machine.

The axial straightening force accepted by the fixed pads of the correct rollers of the lower row of cassettes, the same protrusion on the pillow of the lower right roller, is transmitted to the cassette 3 of the lower row and through the protrusion 8 of the transshipment pallet 7 to the bodies of the outer cassettes of the lower row

Inserts fixed on the outer surfaces of the extreme cassettes close the axial force to the frame. It Moving the cassettes 2 of the upper row with the supporting 5 and right 4 rollers relative to each other and relative to the bed 1 when adjusting the clearance necessary for straightening between the upper and lower regular rollers produced by individuals1

vertical vertical movement of mechanism 6 interacting with cassette housings. At the same time, the inserts 17 fixed in the cassette housings move in the vertical grooves of the adjacent cassettes, and the inserts 18 of the outer cassettes move in the slots formed by the bed 1 and the axial fixation mechanism shield 19.

In the event of a misalignment of the course of the vertical movement mechanism 6 interacting with one cassette, the inserts 17 and 18, the side surfaces of which are made radially, allow the cassettes to tilt relative to each other in the vertical plane.

When straightening sheets with curvature with well edges, pillows of one correct roller can be installed at different height levels due to a cassette tilt in a vertical plane, which expands the technological capabilities of the machine. The assembly of the cassette of the upper row is as follows.

In the longitudinal groove 10 of the cassette case 9, a mechanism 12 is installed for adjusting the support rollers in height, and then the case 11 of the support rollers 5. The pillows 13 and 14 of the correct rollers 4 are inserted into the same groove, and the cushion 1.4 enters the transverse case with its projection 15 . 9 cassettes for fixation in the axial direction. Using the buffer device 16, each cushion 13, 14 is connected to the cassette body 9 and the correct rollers 4 are pressed against the support rollers 5. The springs in the buffer device 16 can be pre-compressed nonyijeHo by supplying fluid under pressure to the buffer cavity. The housings of the upper cassettes 2 thus assembled are interconnected by means of inserts 17, limiting the movement of the cassettes relative to each other in the axial direction, but not preventing their vertical movement.

In this form, the set of upper cassettes with a special device (not

shown) falls into the window of the bed 1 of the leveler until the end of the 18 extreme cassettes rests in the frame. 1 1, the axial locking mechanism 19 moves towards each other and the outer cassettes are fixed relative to the frame. Similarly, assembling of cassettes of the lower 10th row is performed. Only the assembled cassettes are not interconnected by means of inserts, but are mounted on the transfer pallet 7 and are combined into a single block by the projections 8 of the pallet. 15 A set of lower cassettes on a pallet with a special device (not shown) is poured into the frame window up to the stop of the latches of the extreme cassettes into the frame and fixed in the axial direction by the shields of the axial locking mechanism 19.

The removal and disassembly of sets of upper and lower cassette rows is carried out in the reverse order.
