A fully automatic strong cooling single-arm stone multi-piece processing combined circular sawing machine

Abstract

A full-automatic intensive cooling single-arm multi-stone machining combined circular sawing machine comprises an automatic tool feeding and retracting hydraulic mechanism and a displacement feeding mechanism, wherein the displacement feeding mechanism can automatically adjust the positions of stones so as to achieve continuous stone cutting without halt. The combined circular sawing machine is characterized in that an intensive cooling flushing mechanism is provided with a booster pump, the booster pump is connected with a water pressure gauge through one high pressure pipe and connected with a transverse spray pipe through the other high pressure pipe, ball valves are arranged on the high pressure pipe between the booster pump and the transverse spray pipe and the high pressure pipe between the booster pump and the water pressure gauge, the ball valves are used for adjusting connection and disconnection and the quantity of water, a connector is arranged on a flow diversion water tank, nozzles are connected to the connector, and the water outlet of each nozzle is right opposite to the portion between two circular saw bodies. Under the effect of high pressure water, the device can make a tool of a combined circular saw fully cooled, residual stone ballasts between tool teeth and two blades are flushed away, deformation of the tool is reduced, the service life of the tool is prolonged, and the energy-saving effect is good.

Description

technical field [0001] The invention relates to a single-arm stone multi-piece processing combined circular sawing machine, in particular to a fully automatic strong cooling single-arm stone multi-piece processing combined circular sawing machine. Background technique [0002] The commercially available single-arm stone multi-piece processing combined circular sawing machine is aimed at processing the whole stone into multiple stone slabs with the saw. The combined circular sawing machine includes three or more than three circular saw blades. On the main shaft, the main shaft drives its rotation through the main motor and the belt transmission mechanism to realize cutting. The main shaft is driven up and down by the hydraulic mechanism to realize feeding and retracting, and the working table is pulled through the combined circular saw through the feeding mechanism to realize the cutting of the stone. cutting. There is a water tank above the combined circular saw, and there ...

AI Technical Summary

Problems solved by technology

There is a water tank above the combined circular saw, and there is a slit at the bottom of the water tank. When the combined circular saw is working, water flows out from the slit of the water tank to cool and rinse the cutter. Usually, the water flows naturally by gravity. As for the combined circular saw, due to the large diameter of the tool, and the rotation of the tool during the working process, a large centrifugal force and a huge wind force are generated, so as soon as the water touches the circular saw, it will be thrown away by the huge wind force and centrifugal force. It can be seen that it basically does not have the effect of cooling the tool and cleaning the gap between the teeth and the residual gravel between the two blades. The direct consequences are: the circular saw cannot be fully cooled, and the circular saw blade is not fully cooled during the cutting process. Under the double action of the high temperature generated and the slag accumulated between the two blades, it is easy to deform the circular saw and seriously affect the life of the tool. At the same time, the deformed tool will directly have a negative impact on the quality of the processed slate.

To replace a set of circular saws, depending on the quantity, often costs tens of thousands or even tens of thousands of yuan. Practice has proved that on the traditional single-arm stone multi-piece processing combined circular saw machine, the service life of the tool is only about half a year.

Secondly, the power of the motor driving the main shaft of this single-arm stone multi-piece combination circular sawing machine is above 60KW, and the starting current is very large. After a piece of stone is partially sliced, it usually has to stop, and the other part of the stone is moved to processing. After the position, restart the main motor, the motor will waste a lot of energy if the motor is started so frequently
