Abstract

The invention relates to the industry of building materials and can be used in the manufacture of ceramic wall materials and drainage pipes. the invention is to improve the quality of hollow products by reducing the deformation of the walls of the product under the action of the cutting string, improving the conditions of operation and simplifying the design. The installation contains a belt press 1 with a puncher, at the end of which a rod 4 is fixed, located inside the hollow bar 2. The free end of rod 4 is made with beveled surfaces lying 1CHI in the planes of movement of the cutting string. The conveyor 8 for receiving the clays of the hollow beam 2 by means of a chain transmission is coupled with a cutting device which contains the cutting frame 16, the drive 17 for its reciprocating movement along the guides 1 of the rotary frame mounted on the common frame 14 by means of hinges 13. For a smooth and silent stop the rotary frame in the final positions are provided dampers 22. The mechanism of rotation of the rotary frame is made in the form of a fixed

The invention relates to industrial construction materials and can be used in the production of drainage pipes and other hollow products.

The purpose of the invention is to improve the quality of hollow structures by reducing the deformation of the walls of the product under the action of the cutting string, improving operating conditions and simplifying the design.

FIG. Figure 1 shows a schematic diagram of the molding and cutting of a clay bar; figure 2 - installation, front view; in fig. 3 is a view And in figure 2,

The installation contains a belt press 1 for forming a hollow beam 2 with the help of a hollow core 3 and a rod 4, which at one end is attached to a hollow core 3. The other end of the rod 4 is made with a slanted hole 5x 5 in planar 6 displacement of the cutting string 7, The installation also includes a conveyor 8 of a hollow beam 2, a conveyor 9 for receiving cut-off products and a cutting device made in vi, tse. a pivoting frame 10 with guides of the PI 12 mounted by means of the hinges 13 on a common frame 4. The guides 11 and 12 are made under the HHKii 15 rolling pivot, by which the cutting frame 16 with the string 7 is moved along them. The cutting frame 16 receives movement from the actuator 17 of the reciprocating movement, and its weight is balanced by the spring 18, the swivel frame 10 v, the extreme tilt positions are held by the fixing spring 19, which is fixed at one end on the rotary frame 10 at the point 20 lying above its axis rotation and the other on

common frame 14 under this axis. The prullsin 2i repeller is attached at one end to the cutting frame 16 at the level of the axis of the cutting string 7, and the other end to the common frame 14 at the level of the rotation axis of the rotary frame 10. For a smooth translation of the rotary frame 10 from one tilt position to another, dampers 22 are provided, which They also function as limiters for rotation. In addition to the rod 4 placed in the cavity 23, to prevent deformation of the walls of the product under the action of the cutting string 7, upper 24 and lower 25 smoothing strips are provided that are installed outside the hollow beam 2. - ca 2 by means of its kinematic connection with the conveyor 8. Maybe. 1; Independent drive in combination with a synchronization device.

The installation works as follows.

Formed with a belt press 1, a hollow beam 2 enters the conveyor 8, which is kinematically connected with the drive I7. The energy of the translational movement of the hollow beam 2 is transformed into a reciprocating movement of the cutting frame 16, which moves along the guides P and 12, the cutting string cuts the hollow beam 2 during its movement B of the plane 6. When the string 7 leaves the hollow beam 2, the force pulling away the springs 2 become larger than the force generated by the fixing spring 19, with the result that the swing frame 10 changes its position to the opposite. The beveled surfaces 5 of the rod 4 prevent deformation of the wall of the hollow bar 2 when the cutting string 7 enters it, and smoothing strips 24 and 25 are provided for this at the exit of the string. Next, the cutting cycle repeats.
