Description

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

Known swinging clip to mashi ⁴ · not for straightening shaped steel, containing the correct gauge and bearing that carries it, the outer ring of which is rigidly connected to the drive cripple; on a slider mounted with the possibility of reciprocating movement in the direction perpendicular to the direction of movement of the rod [ί].

The drawback of the cage is the lack of the possibility of eliminating the torsion of the processed steel on it, which determines the low quality of the finished product. To carry out this operation, it becomes necessary to use additional equipment (spinning machines), which is heavy and occupies a significant production area. thirty

The aim of the invention is to improve the quality of structural steel.

This goal is achieved by the fact that in the cage containing the correct caliber and bearing it, connected with the rod and slide, the rod is mounted on the slide with the possibility of rotation.

The drawing shows a kinematic diagram of a swinging clip to a machine for straightening shaped steel.

The cage consists of a bearing, the outer ring 1 of which is rigidly fixed on the drive crank 2, made adjustable (not shown in the drawing), and the inner ring 3 contains a regular roller gauge formed by four rollers 4. The inner ring 3 is rigidly connected to the rod 5, which passes inside the swinging wings 6 with the possibility of axial movement in it. The link 6 is pivotally mounted on a slider 7, connected through a connecting rod 8 with a drive crank 9, the Slider 7 is mounted with the possibility of movement in the guides 10. The crank 9 is made adjustable in length (not shown in the drawing).

The device operates as follows.

On the machine bed (not shown in the drawing), a series of clips are mounted sequentially, through the rolled calibers of which the processed steel is passed. From the drive cree. ’Of the stud 2, the outer ring 1 of the bearing of each cage rotates. The eccentricity (the distance from the center of rotation of the crank 2 to the axis of the roller gauge) ’О is set by changing the length of the crank 2. Its value for each wallpaper ΰ is selected from the condition for editing the longitudinal curvature of the product. When the drive crank 9 rotates, the connecting rod 8 15 informs the slider 7 of the reciprocating movement along the guides 10 of the bed. The swinging arm 6 pivotally mounted on the slider 7 pumps the rod 5. In this case, the inner ring 20 of bearings with a roller gauge rigidly connected to the rod 5 is rotated by a certain angle. The angle of rotation is adjusted by changing the length -. the crank 9, in the value of it for each holder is selected from the condition for correcting the torsion of the product. ,

Thus, roller gauges simultaneously perform translational motion and rotation at a certain angle. Due to such a movement of the 3D role of new calibers, the processed profile, passing through a series of swinging clips, receives multiple alternating bends and torsion necessary for the correction of products. Moreover, the number of bending and torsion deformations can be independently controlled by changing the rotation speeds of cranks 2 and 9, respectively.

The proposed constructive design of the swinging collar will provide high quality straightening both the longitudinal curvature of the shaped steel and its torsion, due to the possibility of adjusting the number of torsion strains regardless of the number of bending strains.

Claims (2)

The device works as follows. On the frame of the machine (not shown in the drawing), they mount successively a number of clips, through which rolling gauges pass the treatment of the THBaeivftift hire. From the drive crank 2, the outer ring 1 of the bearing of each cage performs a rotational movement. The eccentricity (the distance from the center of rotation of the crook of the spike 2 to the axis of the roller gauge) is set by changing the length of the crook of the spike 2. Its value for each wallpaper is selected from the condition for editing the longitudinal curvature of the product. When the drive crank 9 rotates, the connecting rod 8 informs the slider 7 a reciprocating movement in the directions of the 10 bed. Mounted on the slider 7, the swiveling 6 of the rocker 6 pumps the rod 5. At the same time, the inner ring 3 of the bearings with a roller gauge rigidly connected with the rod 5 rotates through a certain angle. The angle of rotation is adjusted by varying the length of the crank 9, and its size for shrinkage is chosen from the condition of correcting the torsion of the product. - Thus, the roller gauges simultaneously move and rotate at a certain angle. Due to this movement of the roller gauges with the I profile, a passage through a series of swinging collars receives multiple alternating bends and torsion needed to correct the products. Moreover, the number of bending and torsion deformations can be independently controlled by varying the rotational speeds of cranks 2 and 9, respectively. bending deformations. Claim Rolling to the machine for straightening shaped steel, containing the correct caliber and bearing bearing, the outer ring of which is rigidly connected to the drive crank, and the inner one is fixedly connected to the rod installed with the possibility of reciprocating axial movement on a slider mounted to the possibility of reciprocating movement in the direction perpendicular to the direction of movement of the rod, about the fact that, in order to improve the quality of the rolled stock, flax on the slide with the possibility of rotation.
