Description

one

The invention relates to the main technological equipment of the rolling mill, namely to the mills of the transverse wedge mill.

The purpose of the invention is to improve the quality of products by calibrating their ends by smoothing.

Figure 1 shows the camp, front view; figure 2 is the same, top view; on fig.Z - section. A-A in FIG. The device contains two driven working tools 1 and 2 in the form of rolls, two dies 3, installed do axes of rolling on the rods of hydraulic cylinders 4 with the possibility of free rotation, and two mechanisms for locking the dies, each of which can be made in the form of a gear rim 5 of the matrix, an elastic plate 6 fixed at one end on the body of the hydraulic cylinder 4 and having a protrusion on the side of the gear ring of the matrix, and a cam 7 mounted on one of the sides of one of the rolls.

The device works as follows.

The blank 8 is fed to the deformation zone between the rolls 1 and 2,

5 with guide bars (not shown) and matrices 3, where it is deformed by acquiring the desired profile. Simultaneously with the formation of the profile of the workpiece effort

10 hydraulic cylinders 4 end faces of the workpiece are deformed in dies 3, which rotate at the same angular speed as the workpiece, without interfering with its rotation. In a given area of the 5th cam, the cams 7 mounted on one of the rolls come into contact with the elastic plates 6, while their protrusions interlock with the gear rims of the matrices and stop the rotation of the dies 3. The rotating workpiece 8 slips relative to the dies 3, This is done by smoothing the ends of the product by smoothing and, consequently, a quality improvement is achieved.

Claims (2)

1. A DEVICE FOR CROSS-WEDGE ROLLING, containing two driven working tools and two matrices mounted on the rolling axis on the hydraulic cylinder rods with the possibility of free rotation by calibrating their ends by smoothing, it is equipped with mechanisms for locking the matrices in the tangential direction. 2. The device according to claim 1, characterized in that each mechanism for locking the matrix is made in the form of a gear ring of the matrix, an elastic plate fixed at one end to the body of the hydraulic cylinder and having a protrusion from the side of the ring gear of the matrix, and a cam mounted on one of the sides one of the tools with the possibility that it differs in that, in order to improve the quality of the products by the ability to interact with the elastic plate.
