Description

C5U VOLVE SAW MACHINE OF CONTINUOUS CASTING

METALS

one

The invention relates to metallurgy and to volatile saws used, for example, in continuous casting machines.

A known flying saw for cutting long articles, such as pipes and profiles, in a continuous production process, comprises a fixed base frame in which a movable table with a disk disk moves while the disk rotation drive is combined with a reciprocating drive table motion.

Closest to the proposed technical entity is a mobile saw, containing a fixed support, in which it is installed with the possibility of moving the frame with the saw blade and its drive, as well as the clamp for coupling with the material being cut. Cut to measure lengths rolled then

on the transport roller table and removed from the dust fz.

The lack of construction is that they do not allow cutting of the continuous ingot into short blanks in the casting process and their further transportation to the stationary roller table installed in one technological

10 line with a saw. In this case, when the dust carriage is removed, to the initial position by the amount of stroke required for cutting, the distance between the last saw blade and the first stationary roller of the live roll table is large enough, which does not allow transporting short workpieces. This requires installation at the cutting site of the intermediate ingot

20 of the roller section, which complicates the design of the cutting device.

The purpose of the invention is to simplify the design of the cutting assembly. The goal is achieved by the fact that in a flying saw of a continuous metal casting machine containing a support frame and a carriage with a saw disk, a mechanism for its rotation by a grab, guide rollers, the carriage is equipped with a rod with a support roller installed with the possibility of reciprocating movement in the groove of the carriage, the contactors are fixed on the body of the support roller, and the stops interacting with the contactors are fixed on the frame. The drawing shows a flying saw, side view with a partial cut. The flying saw contains the carriage 1, which is moved along the support frame 2 on horizontal rollers and centered by vertical rollers. A gripper 3 is installed on the carriage to synchronize the movement of the carriage with the ingot during cutting, the blade disk rotation mechanism i, which includes a gearbox, an electric motor is mounted on the input shaft, and the blade disk, idle rollers 5 to support the workpiece, the bar 6, entering the groove 7 of the carriage. . At the end of the rod 6, a support roller 8 is fixed in the housing 9. A strap with two stop contactors 10 is attached to the cable from the bottom. There is a stop 11 on the support frame that limits the movement of the roller, and the hydraulic cylinder 12 is installed to return the carriage to its original position after cutting . . The device works as follows. The gripper 3 is engaged with a moving continuous ingot which, when it starts, moves the carriage. The rod 6 together with the support roller 8 fixed on it also moves together with the carriage until the contactor 10 contacts the stop 11, after which the rod 6 stops and the carriage runs over the rod until the cutting process of the ingot is completed. The gripper then releases the ingot and the hydraulic cylinder 12 returns the carriage to its original position. The boom 6 also moves in the opposite direction until the opposite contactor contacts the frame stop. The rod 6 stops and at the same time begins to move out of the carriage, moving to its original position. The process then repeats. Thus, there is no need to equip an area for cutting an ingot with an additional roller table, which simplifies the design of the device and increases its compactness. Claims of the invention The volatile saw of a continuous metal casting machine, comprising a support frame and a carriage with a saw disk, a mechanism for its rotation, a catch, guide rollers, which, in order to simplify the design of the cutting assembly, the carriage is equipped with a bar with a support roller installed the possibility of reciprocating movement in the slot of the carriage, with contactors fixed on the body of the support roller, and stops interacting with contactors on the frame.
