RU2526663C1 - Dust and chips removal system at automatic line - Google Patents

Abstract

FIELD: metallurgy.

SUBSTANCE: proposed system comprises dust and chips intakes arranged in the zone of cutting tools. This system is equipped with collector and two cyclones. Said collector is secured at the line central section, lines being connected thereto from said dust and chips intakes. One of said cyclones is connected with collector bottom part and equipped with constant-action discharge valve for feed of trapped dust and chips over continuous conveyor into pelletiser bin. Another cyclone is equipped with dust collector, its pipe being connected to atmosphere.

EFFECT: higher efficiency of dust and chips removal.

Description

The invention relates to metal processing.

The closest technical solution to the claimed object is the device of a cutting tool with a dust removal system according to SU patent No. 1745519, 1990, which contains a hollow body with a cup cutting element housed therein, a means for connecting the body to the suction system and a tool for fixing the cutter in the tool holder. A reciprocating device is installed on the housing for interacting with the workpiece of the dust collector nozzles, equipped with air supply nozzles located on the cylinder into the body cavity.

The disadvantage of this design is that it is not intended for boring holes, the elastic elements wear out during the cutting process and must be changed, the lack of rigidity of this design can also be attributed to the disadvantages.

When solving the problems of pneumatic removal of dust and chips from cutting elements of a group of machine tools arranged in a line, especially machine complexes of automatic lines, problems often arise in the placement of individual elements of dust collectors, a prefabricated collector, etc., and in the general layout of the pneumatic system.

The technical result is an increase in the efficiency of removing dust and chips from the working area.

This is achieved by the fact that in the dust and chip removal system on an automatic line containing dust collectors that are located in the area of the cutting tools, some of them are equipped with flexible coupling according to the operating conditions of the line, and a collector is fixed in the center of the line to which pipelines from the group dust collectors are connected while the lower part of the collector is connected by a main pipeline to a cyclone, which is equipped with a continuous valve-unloader, and the exhaust nozzle of the fan is connected to a cyclone, which I It is a second stage of air purification from dust and is equipped with a dust collector, while air from the cyclone is discharged into the atmosphere through the pipe, and the chips and dust from the cyclone enter the continuous conveyor 14, which feeds them to the briquette-press hopper.

The drawing shows a diagram of a system for removing dust and chips on an automatic line.

The dust and chip removal system on the automatic line contains dust collectors 5, 4, 2 and 1, which are placed (fixed) in the area of the cutting tools. Some of them are equipped with flexible connection 6 (according to the conditions of the line). In the center of the line, a collector 3 is fixed, to which pipelines from the group dust collectors are connected. The lower part of the collector is connected by a main pipeline to a cyclone 7, which is equipped with a continuous unloader valve 13. The exhaust nozzle of the fan 8 (with an electric motor 9) is connected to a cyclone 11, which is the second stage of air purification from dust and is equipped with a dust collector 12. Air from cyclone 11 was released into the atmosphere through the pipe 10, and the chips and dust from the cyclone 7 enter the continuous conveyor 14, which feeds them into the briquette-press hopper (not shown in the drawing).

The system for removing dust and chips on an automatic line operates as follows.

The drawing shows one of the possible arrangements with the continuous transportation of chips and dust from cutting tools to the place of collection of chips, i.e. to the briquetting site. For the efficient operation of the installation, it is necessary that the air from the cyclone 11 is discharged into the atmosphere through the pipe 10, and the chips and dust from the cyclone 7 enter the continuous conveyor 14, which would supply them to the briquette-press hopper.

The problem of comprehensive removal of elemental chips and dust from the cutting zone, its transportation and briquetting in one technological system is very relevant. Its practical solution is of great socio-economic importance. Shavings are no longer considered production waste - this is a very valuable secondary raw material. However, transportation of shavings from machine-building plants to metallurgical enterprises is associated with high transportation costs. During the remelting of small chips, the loss of metal from fumes reaches 40-50%, while fuel consumption increases, the cost of metal increases.
