Detailed Description

The technical scheme of the invention is further specifically described by the following embodiments and the accompanying drawings.

The utility model provides a nonrust steel pipe grinding device, includes quick-witted case 1 and with quick-witted case 1 unsettled supporting legs, the department upwards caves in the middle of the 1 diapire of quick-witted case has the depressed part 2 of tube-shape, wherein is provided with grating 3 between 2 lateral walls of depressed part and the 1 inside wall of quick-witted case, and grating 3 with the interior separation of quick-witted case 1 be located the polishing chamber 101 of top and be located the medium cooling chamber 102 of below, be provided with in the polishing chamber 101 directly over depressed part 2 and be coniform deburring emery wheel 4, wherein 4 bottoms of deburring emery wheel are connected with 2 intraoral motors 5 of depressed part through the pivot.

Wherein, the side wall of the machine case 1 is provided with a switch door communicated with the bottommost part of the polishing cavity 101, and the side wall of the machine case 1 is provided with a water inlet pipe and a water outlet pipe communicated with the medium cooling cavity 102.

As shown in fig. 1, after the steel pipe passes through the side wall of the chassis 1 and contacts with the deburring wheel 4, the working motor 5 drives the deburring wheel 4 to rotate, the tail end of the steel pipe abuts against the upper half inclined surface of the deburring wheel 4, the inclined surface of the deburring wheel 4 which rotates at the moment can polish and drop burrs and chips at the top end of the steel pipe, and meanwhile, the steel pipe is squeezed to prevent the steel pipe from swinging upwards and rotate so that the edge and corner edges on the notch of the steel pipe can be polished by contacting with the deburring wheel 4, and therefore the edge and the chips at the top end of the steel pipe can be polished to be round.

Polishing the gained piece and dropping at the siltation in chamber 101 bottom of polishing in above-mentioned in-process, the coolant liquid in the medium cooling chamber 102 is cooling back medium cooling chamber 102 this moment, cold air sees through grid 3 and cools off chamber 101 bottom of polishing, and then realize carrying out the artificial intervention cooling to the high temperature piece that the siltation is in chamber 101 bottom of polishing, prevent that this part piece is in the high temperature and influence subsequent processing work, the coolant liquid in time changing medium cooling chamber 102 through inlet tube and outlet pipe prevents that it is in the high temperature simultaneously, and also the recycle of discharged hot water is if being used for washing hands etc..

And a funnel-shaped transparent resin protective cover 6 is arranged in the case 1 positioned at the top of the burr grinding wheel 4, wherein a transparent resin baffle 7 is arranged in the case 1 right above the minimum opening end of the protective cover 6, and a circle of skirt edge 8 positioned right above the burr grinding wheel 4 is also arranged at the bottom of the protective cover 6.

As shown in fig. 1, the protection cover 6 and the baffle 7 prevent the fragments generated during the steel pipe polishing from being splashed out from the top opening of the case 1, so as to protect workers outside the case 1, and meanwhile, the hot gas generated during the polishing can flow out through the minimum opening end of the protection cover 6 and the gap between the baffle 7 and the side wall of the case 1, so as to achieve the purpose of heat dissipation, wherein people can observe the real-time processing working condition of the steel pipe at the top of the deburring grinding wheel 4 through the transparent baffle 7 and the side wall of the protection cover 6, and when the fragments are splashed out from the minimum opening end of the protection cover 6, the fragments can be shielded by the baffle 7 and folded downwards, and finally fall onto the top end face of the protection cover 6, and at the moment, the fragments influenced by gravity can flow back to the minimum opening end of the protection cover 6 along the inclined wall at the top of the protection cover 6, and finally flow back to the bottom of the polishing cavity 101 to be collected.

Evenly be provided with simultaneously on shirt rim 8 and extend to the deburring pipe 10 that removes directly over the deburring emery wheel 4, wherein be located the deburring pipe 10 top edges and corners edge directly over the deburring emery wheel 4 and be provided with sharp cutting edge portion 11, be provided with the fixed pipe 12 that corresponds deburring pipe 10 on the quick-witted case 1 lateral wall, wherein evenly be provided with arc rubber strip 13 along its length direction in the fixed pipe 12, be provided with sheetmetal 14 in the rubber strip 13, wherein the sheetmetal 14 back be provided with fixed pipe 12 inside wall fixed connection's spring 15.

In this embodiment, the guiding portion 16 is obliquely disposed on the inner corner edge of the opening end of the fixing tube 12 to facilitate the insertion of the steel tube, wherein a straight line is formed between the fixing tube 12 and the corresponding deburring tube 10.

As shown in fig. 1, the steel pipe passes through the fixed pipe 12 and the deburring pipe 10 and extends to the top end face of the deburring grinding wheel 4 for grinding, at the moment, the plurality of groups of rubber strips 13 can clamp and fix the steel pipe, and when the case 1 drives the fixed pipe 12 to vibrate during grinding, the rubber strips 13 can buffer and absorb shock for the steel pipe, so as to prevent the steel pipe and the side wall of the fixed pipe 12 from being damaged due to frequent impact, in the process, the metal sheet 14 strengthens the overall strength of the rubber strips 13, and the spring 15 strengthens the elasticity of the rubber strips 13 so as to strengthen the buffering effect.

When the steel pipe is pulled out after polishing, and the polishing end of the steel pipe is pulled out from the deburring tube 10, the blade part 11 scrapes off the chips which may not fall off from the top end of the blade part, and the purpose of removing the residual chips at the polishing end of the steel pipe is achieved.

Preferably, a support rod 9 fixedly connected with the skirt 8 is arranged on the inner side wall of the case 1, and the stability of the skirt 8 is enhanced through the support rod 9.

The present invention has been described in detail, but the above description is only a preferred embodiment of the present invention, and is not to be construed as limiting the scope of the present invention.
