Abstract

The invention relates to the field of machine tools, in particular to devices for fencing the cutting area of machine tools. The aim of the invention is to increase the durability of the enclosure by preventing chips from attaching to its inner walls. The device contains located on the upper limb of the frame 1 along the entire perimeter of the shield in the form of flat bags 4, fixed with the help of strips 5 and forming an elastic-elastic inflatable casing. The compressed air is supplied to each bag by means of a nipple 6 from the main. The inner surface of each of the bags is made of a lint, the nap 7 of which is directed downward at an angle that is selected on the basis of the condition that the chips fall without reflection on the transport device 3. 4 Il.

The invention relates to the field of machine tools, in particular to devices for protecting the cutting area of machine tools from flying chips and splashing coolant, and is an improvement of the invention in the author. St. No. 1090534.

The aim of the invention is to increase the durability of the enclosure by preventing the chips from striking its inner walls.

FIG. 1 shows a device placed on the machine table, a general view; in fig. 2 - the same, top view; in fig. 3 is the same longitudinal section in FIG. 4 shows section A-A in FIG. 3

The device consists of a frame 1,

covering the perimeter of the table stand-20 box-shaped fence (casing).

ka, the lower limb 2 of which is included in the drainage groove of the table. On the bottom side of the frame 1 is fixed transport device 3 (chip collector).

On the upper limb of the frame, along the entire perimeter of gravity of the tin falls down, on the transmeter, there are guards in the form of a hermetic device, which removes substantial flat bags 4, fixed with the help of strips 5, forming

her in drive. The inclined arrangement of the villi ensures smooth shaving of the energy of the chips — and,

elastic-elastic inflatable casing.

increases its durability ..

Invention Formula 35 covering the perimeter of the table with the ZOR wear of the inner surfaces of the casing, the gap ... The compressed air is supplied to each bag by means of a nipple 6 connected to the compressed air line through the pneumatic distributor, cured to the bottom of the bag. The inner surface of each of the bags 4 is made of a fleecy, the nap 7 of which is directed downward at an angle chosen from the condition of chip drop without reflection, i.e. I exclude its rekoshetirovaniye. In KAZhDevice for fencing the cutting zone on the ed. St. No. 1090534, due to the fact that, in order to increase durability, the inner surface of the bags is made of Q fleecy and the nap is directed downwards at an angle that is chosen from the condition that the chips fall without reflection. In the case of bag 4, one wall is shorter than the other, and the bag itself is hermetically glued together around the perimeter of elastic material by winding on a mandrel and divided into vertical sections 8. The device works in the following way. In the initial position, the bags 4 are twisted into rolls over the transport device 3 (FIG. 3, dotted line) and opens access from all sides. After installation of the workpiece on the machine, compressed air is supplied to the bags 4. In this case, the bags are straightened and occupy an upright position, forming around the perimeter of the cutting zone Sliver shavings, hitting the inner shaggy surface of the casing, gives up its kinetic energy to the elastic villi and under the action of gravity falls down on a transport device that removes her in drive. The oblique arrangement of the villi provides a smooth extinguishing of the energy of the chips and, preventing increases its durability .. internal surface wear Invention Formula wear of the internal surfaces of the casing, 35 ZO wear internal surfaces of the casing, Device for fencing a cutting zone according to the ed. St. No. 1090534, due to the fact that, in order to increase durability, the inner surface of the bags is made of Q fleecy and the nap is directed downwards at an angle that is chosen from the condition that the chips fall without reflection. s mrm IIIHIIHIIIIIHHIHIIIIIHI i mill Illlllllllllll lUllltnilllll lllltlilllllttl illllllllllllll rra QJUZ.f r-i I r «1 gr Illllltinilirn IIIIIIIIIHIIII IIIIMLUJU Illlll rra; Utl FIG.
