SU139967A1 - Vibromachine for the production of drainage boreless pipes of bituminous-sand mixtures - Google Patents

Description

Vibromachines are known for the production of toothless pipes using nbit bit-sand mixtures. Ethnical machines consist of a vertical bottomless form, a core placed in it and a hopper for a mixture placed above the form. However, they are not highly productive and their work is not automated.

In the proposed machine design, a cutting machine was used at the lower opening of the hole, simultaneously serving to lock the outlet of the mold while filling it with a new portion of the mixture and vibrating the mixture in the mold. To cool the bottom of the hour: the form is equipped with a water scrub. These design features of the machine transform it into a continuously operating installation, fully automate and speed up the pipe manufacturing process.

The drawing shows a diagram of the device of the machine. The machine is equipped with constantly vibrating vibrator / external bottomless molds 2 with inner cores 3. The lower part of the mold is closed with knives of an automatically operating cutting apparatus 4 consisting of electromagnets. lever, turntable, two knives on the pin and frame. The lower part of the mold is equipped with a water scrub 5. The mold is loaded with a bitumen-sand mixture produced from bins.

At the beginning of operation, the lever of the cutting mechanism is manually retracted to the left. The molded tube, under the influence of the weight and pulses of the vibrator, is lowered down until it touches the levers of the multiple mechanism 7 in the water bath. As soon as the tube touches the levers of the receiving mechanism, its brush will move upward under the action of the weight of the tube, turn the switch core 8, and the contacts will close. The current from the power source will pass through the electromagnet winding.

9, and the knives of the cutting apparatus, when turning it to the right, cut the pipe, which will go down to the tilting mechanism, 10, and then - the cattle board, and which will be transferred to the continuous operating conveyor //. The conveyor pipe rises up and enters the finished goods warehouse. After the receiver’s levers pass through the receiving mechanism, its stem will go down, turn the non-switch core, draw the current through the electromagnet core, and the knives of the cutting apparatus will open to pass the next shaped tube. The source of direct current is the generator 12.

Subject invention

Claims (2)

1. A vibromachine for the production of drainage boreless pipes from bitumen-sand mixtures, consisting of a vertical bottomless shape, placed in the form of a core, forming a tube cavity, and a mixture hopper, located above the shape, characterized in that, for the purpose of full automation at the lower outlet of the mold, there is a cutting apparatus with horizontally moving knives, which serve to cut off the part of the finished pipe that has left the mold and to lock the outlet of the mold for the time it starts filling it with a new portion of the mixture from the hopper and for the time of vibroplate of the mixture in the form. 2. A vibromachine according to claim 1, characterized in that, in order to accelerate the process of making pipes from bitumen-sand mixtures that require cooling to give the formed pipe a hardness sufficient to produce subsequent process steps over it, the lower part of the mold is equipped with a water jacket.
