The invention relates to a compressed air-operated chip vacuum cleaner according to the preamble of claim 1, for removing chips during milling.

It is known that chips created during profile milling on plastic and metal surfaces settle on the surface, thereby obscuring the overview and negatively affecting the surface quality.

Until now, chips have been removed during milling by blowing them away using compressed air and a compressed air gun, by rinsing them away using appropriate liquids or by suction using a suction system, which is rarely available even in large companies for cost reasons.

The aim of the furnace is therefore to create a device that would enable all companies that operate profile milling machines to remove chips without exposing the machine operator to the risk of being sprayed with chips, which very often leads to eye injuries.

To solve this problem, the innovative, compressed air-operated chip vacuum cleaner for milling chips, which is preferably attached to a commercially available compressed air gun, is characterized in that the arrangement of the suction pipe forms a sharp angle in relation to the obliquely inserted compressed air nozzle, which, when the compressed air nozzle flows into the suction pipe, creates a negative pressure at the oblique end of the suction pipe, whereby air and chips are sucked in and discharged into the chip container by means of an elastic hose.

Further features emerge from the subclaims. The firing system is described in more detail in the appendix of drawings.

Fig. 1 shows the new compressed air-operated chip vacuum cleaner 1, screwed onto the commercially available compressed air gun 2 in a side view, with the hose 3 for discharging the air-chip mixture attached to the discharge nozzle 10, and the compressed air hose 4 attached to the compressed air gun 2.

Fig. 2 shows the compressed air-operated chip vacuum cleaner 1 as a sectional view of the side view shown in Fig. 1, wherein the housing 5 has the obliquely embedded suction pipe 6 in the upper area, into which the compressed air nozzle 12 leads in the middle area of the housing 5 at a sharp angle to the suction pipe axis 14, wherein the compressed air nozzle 12 is connected to the compressed air nozzle 9 by means of a pipe 7, which is designed as a pipe bend.

Fig. 3 shows the sectional view A-A of the chip vacuum cleaner shown in Fig. 2, in which the design of the compressed air nozzle 9 and that of the upper discharge nozzle are shown.

It is assumed that the compressed air-operated chip vacuum cleaner as part of the set 1, of the commercially available compressed air gun 2, is adapted in terms of operational convenience and application possibilities and is designed accordingly.

In order to achieve this, the compressed air-operated chip vacuum cleaner 1 was constructed as a single part, with the housing 5 being a molded piece, preferably made of plastic or aluminum, in which the steel suction pipe 6 is embedded in an adhesive seat and secured against displacement and twisting by gluing with epoxy resin to the front and rear of the housing 5.

The design of the housing 5 as two pipe sockets running diagonally into each other serves to minimize weight and size, whereby the upper diagonal pipe socket supports the suction pipe 6, the lower horizontal pipe socket 9 serves as a compressed air supply socket, which, by means of pipe 7 designed as a pipe bend, leads the compressed air in a laminar manner into the compressed air nozzle 12 and further into the mixing chamber 13, where negative pressure is created by decompression and directional angle at the suction end 8, which causes the suction of air up to chips.

Claims (3)

PROTECTION VOICES: 1. Compressed air-operated chip vacuum cleaner 1, which is preferably attached to a commercially available compressed air gun, characterized in that the housing 5 in the upper area comprises the suction pipe 6, with its front suction part 8, the compressed air nozzle 12 located in the middle area and radiating into the suction pipe 6 and the rear air-chip discharge nozzle 10 of the suction pipe 6, and in the lower area the compressed air supply nozzle 9 with pipe 7 as a pipe bend, whereby the suction pipe axis 10 forms a sharp angle with the compressed air nozzle axis 11. 2. Pneumatically operated chip vacuum cleaner according to claim 1, characterized in that the housing 5 is designed as a molded piece, preferably as an aluminum or plastic molded piece, as two round nozzles running diagonally into one another, which serves to minimize the dimensions and weight. 3. Pneumatically operated chip vacuum cleaner according to claim 1, characterized in that the suction pipe 6, embedded in the housing 5 in the manner of an adhesive seat, is glued with epoxy resin to the front and rear sides of the upper round socket of the housing 5, which serves to prevent displacement or twisting during use, but enables the replacement of the suction pipe 6.
