Description

of rolling, containing a machine, a saw, a cutting pneumatic cylinder, placed between 1 right between the Machine and a saw bridge with clamp-shaped wires and the main indicator of the cut, installed, in its middle part, a power cylinder, bridged between the bridge and the saw, and the exit table with yinopoM and a resetter, equipped with additional cut indicators, spaced; ennvmi on both sides relative to the main indicator of the cut, and output wiring mounted at the end of the intermediate bridge and mounted on the shaft of the power cylinder with the possibility of movement in the transverse direction by means of a chazhno-cam; a new mechanism, this three saw is mounted motionless.

FIG. 1 shows a device, view in plan; on fi-g. 2 - view A of FIG. one; in fig. 3 shows a section BB in FIG. 2; in fig. 4 shows a section B-B in FIG. 2; in fig. 5 is a view of FIG. four.

The device for straightening and cutting continuously slit; the rolling stock includes the correct machine 1, saw 2, cutting cylinder 3, intermediate IMOCT 4 with clamping wires 5 and cutting TopOiM indicator 6, mounted in the middle of the bridge.

On both sides of indicator 6, at a distance approximately equal to a quarter of the length of the length of the bridge bridge 4, two additional indicators of cut 7 and 8 were placed.

The saw 2 is mounted stationary, and at the end of the intermediate bridge 4, output wiring 9 is installed, which can be moved in the transverse direction from the pneuM | OCylinder of the cut 3.

The pneumatic cylinder 3 acts on the wiring through the lever-cam mechanism 10, which is designed as a lever II, one end of which is pivotally connected to the wiring 9 and the other with the pneumatic cylinder of the cut 3 and also carries a roller 12 rolling around the fixedly mounted cam 13.

On both sides of the output wiring 9, the guiding chutes 14 and 15 are mounted, the wiring itself 9 is installed in conjunction with the springs .16.

The saw 2 consists of a spindle 17, which is driven by the electric motor 18 and carries a saw blade 19.

Each of the indicators 6, 7 and 8 consists of a limit switch 20 and a roller probe 21 mounted on axis 22.

The correct machine 1 contains guide rollers 23, clip 24, and t need rollers 25.

The device also has a figure 26 for loading the rod (blank) 27, the wiring 28 with the supporting stop 29 and

anaportizing rollers 30, as well as receiving table 31.

The operation of the device occurs in the following sequence. On the figure 26, the rod 27 rolled up into the coil is lowered with a crane, the front end of which is loaded into the guide rollers 23, the yoke 24 and the driving rollers 25. Then the drive is turned on correctly

machine 1, which produces the straightening of the car and moves it through the clip; 24 while simultaneously unloading it from the figure 26.

After the bar 27 passes through the intermediate bridge 4, wiring 9 and 28, its front end is pressed into the vanishing stop 29, which at this moment is raised. The workpiece 27 along the length of the intermediate bridge 4 begins to lose the longitudinal

stability and with a small cross section forms a loop in the form of two waves 32, and with a large - in the form of a single wave 33 (Fig. 2).

Lift up (Figs. 4 and 5), the workpiece 27 acts on the probe 21, which, turning around the axis 22, turns off the limit switch 20, which gives a signal to activate the pneumatic cylinder 3. In the case of processing the workpiece 27 of a small cross section, one of the indicators 7 is triggered or 8 and the complete filling of intermediate bridge 4 is not required. This significantly shortens the processing cycle of a single piece of workpiece.

After receiving the signal from the cut indicators, the pneumatic cylinder 3 moves the lever 11 to the left (Fig. 3). The roller 12 at the same time, rolling on the profiled cam 13, moves the wiring 9 together with the clamped

in it, the blank 27 toward the disk 19, which rotates from the electric motor 18 and cuts the blank 27.

At this time, the workpiece 27 is bent in lobs 14 and 15, the length

which are selected according to the conditions of the minimum allowable curvature and perpendicularity of the end face.

Then pivot cylinder 3, continuing its movement without any height,

moves the roller 12 to the extreme left position shown in FIG. 3 thin. In this case, the workpiece 27 and the wiring 9 are returned to their original position by the springs 16. The next cutting cycle is performed

when roller 12 is moved from the leftmost to the far right position. Thus, in one double stroke of the pneumatic cylinder 3, two double strokes of the output wiring 9 are made. Thanks to this

Lila 2 does not hinder the work of the intermediate bridge 4. After cutting, the disappearing stop 29 rises and the length of workpiece 27 in the wiring 28 is equal to the distance from the stop 29 to the disk

19, the rollers 30 are fed to the receiving

table 31. To adjust to a different length of cut, the stop 29 and rollers 30 move along wiring 28.

The cam 13 has a profile that provides the law of variation of the lateral movement (feed) of the workpiece 27, corresponding to obtaining a high-quality end face.

The invention makes it possible to increase the rolling speed of small sizes, for example, copper pipes 6-8X1.0 to 6080 m / min, which improves the manufacturer: iiocTb devices and the quality of

billets.
