Description
Technical field
The present invention relates to a kind of compression ring, the compression ring that uses on particularly a kind of blowing and spraying type steel pipe painting machine to steel tube surface rust prevention by applying liquid material paint.
Background technology
Steel pipe japanning is one of requisite production process in the modernized steel pipe's production, and it mainly act as the fished pipe outer surface is evenly sprayed anticorrosive paint about last layer thickness 10-20 ц m, guarantees the antirust and aesthetic function of steel pipe.
The steel pipe japanning mode that generally adopts both at home and abroad has two kinds at present: a kind of is atomization type, promptly utilize high pressure will paint atomizing and be directly injected into steel tube surface, reach the japanning function, this device advantage is that the steel tube surface japanning is more even, but shortcoming is more, easily cause film thickness to be difficult to guarantee that paint waste is serious, does not reach environmental requirement; Another kind of mode is a blowing and spraying type, at first evenly spoons one deck paint in steel tube surface, blows out gases at high pressure by compression ring again, and the steel tube surface that spoons paint is evenly purged, and paint film evenly is attached on the steel tube surface by technological requirement.The blowing and spraying type steel pipe painting machine characteristics are simple for making, and can freely control film thickness, simultaneously because paint is not with vaporific work, and less wastage, and be beneficial to environmental protection, this kind equipment has the trend that replaces the atomization type paint spraying apparatus gradually at present.
Compression ring is the critical component on the blowing and spraying type steel pipe painting machine, and the compression ring on the existing blowing and spraying type steel pipe painting machine in use often causes steel pipe extension pearl when producing, leaks spray, the unequal problem of film thickness:
1, compression ring on the existing blowing and spraying type steel pipe painting machine as shown in Figure 1, it is made up of interior ring 2 and outer shroud 1, on the annular wall of outer shroud 1, be provided with two threaded air inlets 3, interior ring 2 and outer shroud 1 adopt and are threaded, form the air chamber 4 of an annular between the annular outer wall of interior ring 2 and the annular inner wall of outer shroud 1 by the back that is threaded, air inlet 3 communicates with ring-shaped air chamber 4, gap between the outer inclined-plane on interior ring 2 tops and the interior inclined-plane of outer shroud 1 constitutes air outlet 5 (abbreviation air knife), air outlet 5 gaps will be adjusted by the rotation screw thread, because of accuracy of screw machining requires high, and very easily bonding stuck under the paint environment, adjustment and dismounting difficulty are big.For above-mentioned reasons, it is excessive that the gap of compression ring air port 5 garden Zhou Shangyou has, and what have is too small even closed, causes steel tube surface painting layer inequality like this, and blocked up paint flows on steel tube surface and forms " teardrop ", has a strong impact on steel tube surface quality.Sometimes because the adjustment of 5 gaps, compression ring air port is improper, cause exhaust air rate big, environmental pollution is serious.
2, compression ring work key position is at the air outlet place, and whether its edge of a knife gap evenly is the key that guarantees to purge performance, and what existing compression ring adopted is the acute angle type edge of a knife, thereby directly influences the purging performance in real work Tipping Center angular position easy damaged.
Summary of the invention
The objective of the invention is to overcome the above-mentioned deficiency of prior art and a kind of new compression ring that uses on blowing and spraying type steel pipe painting machine is provided.
Technical scheme of the present invention is: a kind of air ring of blowing and spraying type steel pipe painting machine, ring and outer shroud in it comprises.
In the cylindrical of ring be provided with seal groove and air chamber groove, on an end face of interior ring, be respectively equipped with the composition surface, air port of annular, the air outlet vertical plane of annular and the air outlet inclined-plane of annular, the angle a2 between air outlet inclined-plane and the air outlet vertical plane 30 spends.On the composition surface, air port, be evenly equipped with six trapezoid boss, trapezoid boss is provided with screwed hole, the angle a1 of trapezoid boss two sides is 10 degree, leave the groove of supplied gas circulation between the cylindrical of the bottom surface of trapezoid boss and air outlet vertical plane, trapezoid boss will exceed the end face of air outlet vertical plane, the distance L that exceeds is 0.2mm, and its tolerance is controlled in positive and negative 0.02 scope.
On the cylindrical of outer shroud, be provided with the screw thread air inlet of two symmetries, on the end face of outer shroud one side, be provided with six uniform screw holes.
Interior ring links together by screw with outer shroud, is provided with the O RunddichtringO in the seal groove of interior ring.In ring with after outer shroud is connected by screw, air chamber of formation between interior ring and outer shroud.Form the compression ring air outlet of an annular between the air outlet vertical plane of interior ring and the inner face of outer shroud, the gap of compression ring air outlet is 0.2mm, and its tolerance is controlled in positive and negative 0.02 scope, to guarantee the opening degree of compression ring air outlet.
The present invention compared with prior art has following characteristics:
1, compression ring air outlet gap is formed by machining, and the air outlet opening degree is even, need not adjust, and six screw-drivings with the boss symmetry need only be got final product during assembling, thereby guarantees that air port pressure is even, thoroughly eliminates steel pipe and hangs the pearl phenomenon.
2, the gap of compression ring air outlet 0.2mm is optimal opening degree, can guarantee to purge effect and can make the exhaust air rate minimum again, pollutes thereby reduced the ring jade tablet.
3, the air outlet angle is 30 degree, has reduced the ventilation velocity after blowing, and has also reduced the loss of environmental pollution and paint to a certain extent.
Below in conjunction with the drawings and specific embodiments detailed structure of the present invention is further described.
