; 54) DEVICE FOR EDITING PRODUCTS

one

The invention relates to the processing of metals by pressure, in particular to dressing devices.

A device for dressing is known, containing a regular stand installed on the frame with lower and upper rollers forming closed gauges 1.

The disadvantage of the known device is the impossibility to correct the products of irregular length along the section.

The purpose of the invention is to expand the technological capabilities of the devices. A by ensuring the correction of products unevenly along the section.

The goal is achieved due to the fact. that the upper rollers are installed with the possibility of simultaneous. Returned | Yapizuyatelno move along the axis of edits and perpendicular to it and is spring-loaded. In addition, the device is equipped with a clamping device and an axially movable stop.

1 shows a diagram of the device; figure 2 is a diagram of the second variant of the device; on fig.Z - section aa in figure 1; figure 4 - section bb in figure 1; in Fig.5-- section bb in

2; figure 6 is a cross section in the initial position; Fig. 7 shows a second embodiment of the profile roller.

The device comprises a frame 1, on which a sequentially mounted clamping device 2, a stand 3 and a guide device 4 are mounted; The fixture 2 consists of two prisms 5 and 6, one of which is connected to the drive 7.

Cage 3 has an upper 8 and lower 9 rows of rollers. Bottom row 9 consists

, from the fixed frame 10, on which the profile rollers 11 are mounted. Their profile 12 corresponds to the adjacent surface of the rolled product 13. At the end of the lower row of rollers 9 there is a movable stop 14, which is installed depending on the length of the product 13. Profile rollers of the upper p yes 8 the goal of Nyomie I.LI can be fulfilled from two identical profile disks 15, between which the intermediate disk 16 is located.

The upper movable row 8 consists of a frame 17 located in the guide 18 of the bed 1. On the frame 17

plate 19, spring-loaded profile rollers 20 and profile 21 are mounted, which correspond to the adjacent surface of the rolled product 13.

Between the frame 17 and the plate 19 there are limiting stops 22. The upper row of rollers is repositioned and adjusted by driving mechanisms 23 and 24. The mill has a cooling device in the form of the mentioned profile rollers 11 and 20. Each roller has radial holes

25 connected by annular grooves

26, located on its outer surface. The rollers axes 27 have holes 28 for coolant supply and are distribution pipes.

According to the second embodiment of the device, the lower gauge consists of a fixed beam 29 mounted on the frame 1 and having openings for the supply of cooling liquid. The profile 30 of the beam 29 corresponds to the adjacent surface of the product 13.

The device works as follows.

Hollow thin-walled products with unequal cross-sectional shape along the length are made.

having a small cylindrical tail and a working part of a complex profile formed by a cylindrical convex surface and a groove along the generatrix of the triangular profile.

Claims (2)

1. A device for dressing products containing a regular stand installed on the frame with upper and lower rollers forming closed gauges, is distinguished by the fact that, in order to expand the technological capabilities of the device by ensuring the products are edited unevenly in length, the upper rollers are installed simultaneous reciprocating movement along the axis of the straightening and perpendicular to it and spring-loaded. 2. The device according to claim 1, characterized in that it is provided with a clamping device and an axially movable axial direction.
