Abstract

Appointment: production of building products. The inventive press for forming building products includes a power cylinder with a pressing piston, the rod of which is connected to the drive of its reciprocating movement, an extruder perforated head, pipelines for supplying hot water and hot air to the molding cavity of the power cylinder housing, a screw the loading mechanism in communication with the window of the molding cavity, while the auger shaft is driven by the stroke of the rod using gear rack and belt gears, rack and pinion gear and fastened to the stock, and the final gear via a belt drive is associated with the pulley shaft of the screw. 3 ill.

Description

The invention relates to the manufacture of building products.

The purpose of the invention is to simplify the design and reduce the energy consumption of the drive.

Figure 1 shows the press, the main view; figure 2 is a view of figure 1; in Fig.3 - view B in Fig.1.

The press for forming building products includes a power cylinder 1 with a pressing piston 2 and a rod 3, an extruder perforated head 4, pipelines for supplying hot water 5 and hot air 6 to the molding cavity 7 of the power cylinder 1, and a screw loading mechanism 8 in communication with window 9 of the molding cavity 7, while the shaft 10 of the screw 8 is driven by the stroke of the rod 3 by means of a rack-and-pinion gear 11 and a belt 12 gears; the rack 13 of the rack and pinion gear 11 is mounted on the rod 3, and the gear 14 of the latter is connected via a belt gear 12 to the pulley 15 of the shaft 10 of the screw 8, which is turned on by the electromagnet 16 through the coupling 17.

The operation of the press for forming building products begins with the pressing piston 2 of the force cylinder 1 moving downward and squeezing the moldable mass from the molding cavity 7 through an extruder perforated head 4.

When the piston 2 is sufficiently small upward, hot water 5 for cleaning and hot air 6 for drying the extruder perforated head 4 are sequentially switched on.

With a further rise of the pressing piston 2, the supply of hot water 5 and hot air 6 stops, the electromagnet 16 is activated, transmitting through the coupling gear rack and pinion 11 the transmission gear 12 the rotation of the shaft K of the screw 8, loading the moldable mass through the window 9 into the molding cavity 7 power cylinder 1.

In the extreme upper position of the pressing piston 2, the electromagnet 16 disconnects the gear rack through the clutch 17
