Abstract
The utility model provides a pneumatic sand blasting gun used for surface sandblasting of a workpiece. The pneumatic sand blasting gun comprises a gun body, a lock nut, an air inlet tube, a material sucking tube, a sand blasting tube and a mixing chamber. The gun body is connected with the lock nut in a threaded mode, a front end with an air inlet port of the air inlet tube stretches into an inner cavity of the gun body and the air inlet tube is connected with the gun body. One end of the material sucking tube stretches into the inner cavity of the gun body and the material sucking tube is connected with the gun body. The sand blasting tube is installed inside the lock nut, and a front section of a sand blasting passage inside the sand blasting tube is horn-shaped. The mixing chamber is communicated with the air inlet tube, the material sucking tube and the sand blasting passage on the junction where the mixing chamber is connected with the lock nut inside the gun body. The pneumatic sand blasting gun has the advantages of long service life and extremely high sandblasting efficiency.
Description
Technical field:
The utility model relates to a kind of surface of the work derusting by sandblasting instrument, particularly be a kind of hand
Hold the pneumatic sand blasting rifle.
Background technology:
The steel construction surface all must be through polishing before the application, and preliminary treatment such as sandblast make the workpiece rust cleaning and reach suitable surface roughness; Just can spray, present most surfaces coating decoration team for outdoor or small batch workpiece, still carries out the hand operated grinding wheel polishing; Polishing, speed is slow, and production efficiency is low; And for some dead angles, cheat recessed surface and all can't construct, if use sand-blasting machine; Because of the restriction that receives place or cost can't realize, behind the spraying lacquer, the existing picture that defective needs are done over again often appears checking and accepting.The a lot of producers of existing market use homemade sand-blasting gun, and service life is shorter, and efficient is extremely low.
The utility model content:
The purpose of the utility model is for overcoming above deficiency, a kind of long service life is provided, the hand-held pneumatic sand-blasting gun that sandblast efficient is high.
The purpose of the utility model realizes like this:
The utility model pneumatic sand blasting rifle comprises the rifle body, the locking nut that is threaded with the rifle body; The front end of bringing the gas interface into stretches in the rifle intracoelomic cavity and the air inlet pipe that is connected with the rifle body; One end stretches in the rifle intracoelomic cavity and the suction tube that is connected with the rifle body, is loaded on the blast tube in the locking nut, and the sandblast passage leading portion in the blast tube is shaped as tubaeform; In the rifle body, the mixing chamber that communicates with air inlet pipe, suction tube, sandblast passage is being arranged with the locking nut joint; Improve sandblast efficient, blast tube can adopt high-abrasive material to process long service life.
Above-mentioned sandblast passage back segment is shaped as straight tube shape.
Above-mentioned sandblast passage back segment is shaped as inverted tubaeform, and the stage casing that is positioned between front and rear sections is shaped as straight tube shape, forms the Venturi tube structure, enlarges sand material projected area.
Be compounded with wearing layer on the above-mentioned blast tube inwall.
Be compounded with wearing layer on the above-mentioned air inlet pipe leading portion outer wall.
On the above-mentioned locking nut rear end inner rim sealing ring is housed.
During the utility model work; Through pipeline the air inlet pipe intake interface is connected with air compressor machine; Through inhaling the sand flexible pipe suction tube is communicated with barrel, when compressed air gets into the rifle intracoelomic cavity, in mixing chamber, produces negative pressure, from the suction tube suction from air inlet pipe; The sand material mixes the back with compressed air at mixing chamber and sprays at a high speed from blast tube, impacts surface of the work and carries out blasting treatment.
The utility model is at air inlet pipe leading portion outer wall, blast tube inwall difference complex abrasion-proof layer; When the sand material flows in the rifle body; Can prevent that the sand material from puncturing the air inlet pipe front end, secondly, when sand material and air during in the mixing chamber flow at high speed; Can prevent of the wearing and tearing of sand material, improve whole service life rifle body inwall.The blast tube front end is tubaeform, makes the sand flow more smooth and easy, adopts the Venturi tube structure, enlarges sand material projected area, improves sandblast efficient greatly.
The utility model is simple in structure, long service life, and sandblast efficient is high, and workpiece is handled the requirement that any position, back all can reach national rust cleaning standard GB82923-88Sa2.5 level fully, can be widely used in the surface treatment industry.
Description of drawings:
Fig. 1 is the utility model structural representation.
Fig. 2 is a blast tube structural representation among Fig. 1.
Fig. 3 is another structural representation of blast tube.
The specific embodiment:
Referring to Fig. 1, Fig. 2; Present embodiment pneumatic sand blasting rifle; Comprise rifle body 1, the locking nut 6 that is threaded with the rifle body, the front end of bringing gas interface 2-1 into stretches in the rifle intracoelomic cavity and the air inlet pipe 2 that is connected with the rifle body; One end is oblique stretch in the rifle intracoelomic cavity and with the suction tube 7 of rifle body welding, be loaded on the blast tube 5 in the locking nut.Sandblast passage 5-1 leading portion in the blast tube is shaped as tubaeform, and back segment is shaped as inverted tubaeform, and the stage casing that is positioned between front and rear sections is shaped as straight tube shape.In the rifle body, the mixing chamber 4 that communicates with air inlet pipe, suction tube, sandblast passage is being arranged with the locking nut joint.
Be compounded with wearing layer 9 on the blast tube inwall.Be compounded with wearing layer 3 on the air inlet pipe leading portion outer wall.On the inner rim of locking nut rear end sealing ring 8 is housed.
When compressed air passes through from air inlet pipe 2, the root a tree name inhales penetrates principle, mixing chamber 4 in, produces negative pressure, drives the sand material from suction tube 7 suctions, sand material and compressed air after mixing chamber 4 mixes from blast tube 5 high speed ejaculations.
Sandblast passage in the blast tube also can adopt structure shown in Figure 3, and promptly leading portion is tubaeform, and back segment is a straight tube shape.
