[0002] The short steel tubes used in the production of automotive parts usually have high precision requirements and specific performance indicators. They can be used to manufacture various key components, such as drive shafts, steering system components, connecting rods of suspension systems, brake system components, fuel system components, and supporting components in body structures.

[0003] Seamless short steel pipes need to be polished and cleaned before formal processing to remove dirt, grease and other impurities on the surface. The basic process of polishing and flushing seamless short steel pipes is as follows:

[0004] 1. Initial water washing: Use flowing water to wash the surface of the steel pipe to remove dust, sand and other debris visible on the surface;

[0005] 2. Chemical degreasing: immerse the steel pipe in a tank containing a special degreasing agent, so that the degreasing agent can fully contact and dissolve the surface oil stains;

[0006] 3. Secondary water washing: after chemical degreasing, it is necessary to rinse with clean water to remove the residual degreasing agent;

[0007] 4. Grinding to remove the oxide scale, welding slag, scratches, burrs and other defects on the surface of the steel pipe to ensure a smooth surface;

[0008] 5. Wash three times with water to remove the iron filings left after grinding;

[0009] 6. Discharge the material.

When the seamless short steel pipe 8 rolls out from the discharge ramp 1014, the loading unit falls down, so that only one seamless short steel pipe 8 can slide out at a time;

[0083] like Figure 6 As shown, there are multiple feeding slots 1015, and they are arranged along the length direction of the seamless short steel pipe 8. A certain distance is left between two adjacent feeding slots 1015 to facilitate the entry of the initial washing clamping unit 1024 for clamping operation; when the seamless short steel pipe 8 enters the feeding slot 1015, as shown in FIG. Figure 5 As shown, the primary washing turntable 1022 moves so that one of the primary washing clamping units 1024 is aligned with the loading slot 1015, and the primary washing telescopic unit 1023 is extended at this time, so that the primary washing clamping unit 1024 clamps the seamless short steel pipe 8 in the loading slot 1015, and the turntable rotates to take out the seamless short steel pipe 8 and downwardly enters the primary washing slot 1021;

[0084] The nozzle 305102161025 in the primary washing tank 1021 washes the seamless short steel pipe 8 to remove dust, sand and other debris visible on the surface;

[0085] As the primary wash turntable 1022 rotates, the primary wash clamping unit 1024 moves to the vicinity of the front wash placement slot 1026 (see Figure 8 , Figure 8 Although the front wash placement tank 2 10211 is shown, the actual principle is the same as that of the front wash placement tank 1 1026), at this time, the initial wash telescopic unit 1023 is extended, the initial wash clamping unit 1024 is loosened, and the seamless short steel pipe 8 falls into the front wash placement tank 1 1026 under the action of gravity; the front wash placement tank 1 1026, the front wash placement tank 2 10211, and the front wash placement tank 3 10217 are arranged in the same manner as the feeding placement tank 1015, and multiple ones are arranged in the length direction of the seamless short steel pipe 8, and a certain distance is left between two adjacent ones, so as to facilitate the clamping mechanism to clamp;

[0086] The de-oiling turntable 1028 drives the de-oiling telescopic unit 1029 to the vicinity of the front-washing placement tank 1026, and the de-oiling telescopic unit 1029 extends, so that the de-oiling clamping unit 10210 can clamp the seamless short steel pipe 8, and then the de-oiling turntable 1028 moves, driving the seamless short steel pipe 8 to immerse in the de-oiling agent in the de-oiling tank 1027 to dissolve the surface oil stains; as the de-oiling turntable 1028 drives the seamless short steel pipe 8 to rotate to the vicinity of the front-washing placement tank 2 10211, as shown in FIG. Figure 8 As shown, the de-oiling telescopic unit 1029 cooperates with the de-oiling clamping unit 10210 to place the seamless short steel pipe 8 into the second front washing placement tank 10211;

[0087] The action mode is the same as the previous process. The second-wash clamping unit 10215 clamps the seamless short steel pipe 8 in the second front-wash placement tank 10211. The second-wash turntable 10213 transports the clamped seamless short steel pipe 8 to the second-wash tank 10212 for washing. The second-wash clamping unit 10215 outputs the washed seamless short steel pipe 8 to the third front-wash placement tank 10217.

[0088] The first transfer unit 5 clamps the seamless short steel pipe 8 in the front washing placement tank 3 10217 and places it on the support roller 2013 of the first grinding device 201. Fig.11 As shown, the supporting rollers 2013 are arranged in pairs of two, and a plurality of supporting rollers 2013 are arranged at intervals, and a certain distance is left between two adjacent pairs of supporting rollers 2013, so that the transport clamping unit 504 of the first transport part 5 can enter to clamp and place the seamless short steel pipe 8; the design of the supporting rollers 2013 can, on the one hand, play a role in supporting the seamless short steel pipe 8, and on the other hand, when the seamless short steel pipe 8 rotates, the supporting rollers 2013 will not have any obstruction;

[0089] like Fig.10 As shown, when the seamless short steel pipe 8 is placed on the supporting roller 2013, the grinding telescopic unit 2017 is extended, so that the grinding clamping unit 2018 can clamp one end of the seamless short steel pipe 8, and the grinding telescopic unit 1 2014 is extended, so that the grinding sheet 1 2015 enters the seamless short steel pipe 8, and the grinding telescopic unit 2017 is extended, so that the grinding sheet 20111 contacts the surface of the seamless short steel pipe 8, and then the grinding rotating unit 2016 rotates, and the grinding sheet 1 2015 continues to penetrate into the steel pipe under the action of the grinding telescopic unit 1 2014, and the grinding sheet 2 20111 is driven by the sliding seat 2019 to move along the sliding shaft 2012, driving the grinding sheet 20111 to grind the surface of the steel pipe;

[0090] Due to site limitations, the grinding telescopic unit 2014 cannot move the grinding sheet 2015 from one end of the steel pipe to the other end. Therefore, the present embodiment provides two grinding devices 201 with opposite directions. When the first grinding device 201 completes the grinding, the grinding transfer unit 202 transfers the seamless short steel pipe 8 to the second grinding device 201 to continue grinding.

[0091] When the second grinding device 201 is finished grinding, the grinding transfer unit 202 transfers the seamless short steel pipe 8 to Fig.13 On the grinding and dumping device 204 shown, the seamless short steel pipe 8 is clamped by the dumping clamping unit 2045, and the dumping telescopic unit 2041 is extended, so that the seamless short steel pipe 8 is in a vertically inclined state, so that the grinding debris can be dumped out. Preferably, a waste box 2046 is provided on one side of the grinding and dumping device 204 of this embodiment for receiving the dumped debris; preferably, a vibrator is also provided on the rotating plate 2044, so that the debris adsorbed on the seamless short steel pipe 8 can fall off through vibration;

[0092] When the dumping is completed, the second transfer part 6 transfers the seamless short steel pipe 8 from the grinding and dumping device 204 to the rear-wash placement tank 1 306 (the settings of the rear-wash placement tank 1 306 and the rear-wash placement tank 2 307 of this embodiment are the same as the front-wash placement tank, which will not be repeated here), and the rear-wash turntable 302 moves so that one of the rear-wash clamping units 304 is aligned with the rear-wash placement tank 1 306. At this time, the rear-wash telescopic unit 303 extends out, so that the rear-wash clamping unit 304 clamps the seamless short steel pipe 8 in the rear-wash placement tank 1 306, and the turntable rotates to take out the seamless short steel pipe 8 and downwardly enters the rear-wash tank 301; the nozzle 305 in the rear-wash tank 301 rinses the seamless short steel pipe 8 to remove excess debris on the surface and inside;

[0093] As the rear wash turntable 302 rotates, the rear wash clamping unit 304 moves to the vicinity of the rear wash placement tank 2 307. Here, as shown in FIG8, the rear wash telescopic unit 303 cooperates with the rear wash clamping unit 304 to place the seamless short steel pipe 8 into the rear wash placement tank 2 307;

[0094] The post-washing transfer unit transfers the seamless short steel pipe 8 in the post-washing placement tank 2 307 to the rear end dumping device 308. The rear end dumping device 308 is constructed in the same manner as the grinding dumping device 204. The movement is not traced here. The difference is that a blower mechanism can be provided at the end of the rotating plate 2044 of the rear end dumping device 308. Preferably, the blower mechanism can be a hot air blower mechanism. When the seamless pipe is just in a vertically inclined state, the blower mechanism can blow air downward to accelerate the water on the seamless short steel pipe 8 to slide downward or evaporate.

[0095] After dumping is completed, the third transfer unit 7 transfers the seamless short steel pipe 8 on the rear end dumping device 308 to the discharge unit 4, which can be a recycling box, such as Fig.15 As shown, the third transfer part 7 rotates to an oblique downward direction, the clamping unit is released, and the steel pipe can fall into the recovery box.

[0096] The telescopic unit, the clamping unit, and the lifting unit involved in this embodiment can all adopt cylinders, and the movement of the turntable and the rotating unit can be achieved by a servo motor.

[0097] The above embodiments are only used to explain the concept of the present invention, rather than to limit the protection of the present invention. Any non-substantial changes to the present invention using this concept shall fall within the protection scope of the present invention.
