Description

Technical Field

[0001] The present invention relates to the technical field related to profile processing, and more specifically, to an inner hole burr removal device for profile processing. Background Art

[0002] Profiles are objects with certain geometric shapes made of iron or steel and materials with certain strength and toughness (such as plastic, aluminum, fiberglass, etc.) through rolling, extrusion, casting and other processes. The classification of steel sections: According to the different smelting quality of steel, steel sections are divided into ordinary steel sections and high-quality steel sections. Ordinary steel sections are divided into large steel sections, medium steel sections and small steel sections according to the current metal product catalog. Ordinary steel sections can be divided into I-beams, channel steels, angle steels, H-shaped steel sections, round steel sections, etc. according to their cross-sectional shapes. Therefore, during the profile processing process, the inner hole burrs of the profile need to be removed to facilitate the subsequent sales of the profile. Therefore, an inner hole burr removal device for profile processing is required.

[0003] However, the existing profile inner hole burr removal machines can only process profiles of a single size during the burr removal process, and all use a single workstation, which not only prolongs the processing time, but also has low processing efficiency. In addition, the profile debris is currently collected by a vacuum fan or unified cleaning. The vacuum fan is close to the processing table when working, and the noise will be relatively loud, which is easy to affect people around. If the vacuum fan is far away, the efficiency of sucking debris will also be affected. At the same time, unified cleaning adopts manual methods, which is time-consuming and labor-intensive, and is not efficient.

[0004] Therefore, a device for removing burrs from inner holes for profile processing is needed. Summary of the invention

[0014] 1. In the present invention, under the driving action of the second driver, gear 1 and gear 2 work simultaneously. Since gear 1 and the control plate, and gear 2 and the movable bar are meshed and connected, gear 2 drives the movable bar to move forward and backward under the cooperation of the slider and the slide groove, and can drive the clamping structure at the front of the movable bar to move to a suitable position. During the rotation of gear 1, gear 2 will also drive the control plate to rotate, which can increase the sliding speed of the movable bar, and after the movable bar is stable, the stability of the clamping structure can be increased. The clamping bar is set according to the circular shape of the profile, which can conveniently clamp and fix the profile to be processed, and the sponge bar can increase the friction between the clamping bar and the profile to avoid falling during the profile processing.

[0015] 2. In the present invention, the pad plays a preliminary supporting role for the profile, and cooperates with the external exhaust fan and exhaust pipe by relying on the suction hole. When the exhaust fan works to absorb, the air flow rate around the noise reduction guide plate below the waste chip collection frame will be increased. At this time, the noise reduction guide plate rotates under the rotation of the rotating rod, and the debris generated during the profile processing can be drained into the exhaust pipe to prevent the debris from flying around. Because in the traditional process, the hair dryer and the blowpipe directly absorb the debris, which is easy to generate noise, the use of the noise reduction guide plate can not only drain but also play a role in noise reduction;

[0016] 3. In the present invention, when the hydraulic cylinder is working, it drives the burr removal structure to move up and down as a whole. Under the driving action of the first driver, the moving ring in the burr removal structure will rotate on the screw rod. At this time, the connecting strip rotatably connected to the moving ring will change the inclination angle of the connecting strip as the moving ring is subjected to pressure or recovery force when it descends or rises. At this point, the knife strip and the knife body will become larger or smaller under the traction of the connecting strip. Therefore, it can be adjusted according to the size of the profile aperture and can adapt to different profile apertures. The burr removal structure can only rotate after it is connected to an external driving device as a whole, and the internal burrs of the aluminum profile can also be removed through the knife body.

[0029] In a specific implementation manner, under the driving action of the second driver, gear one 9 and gear two 10 work simultaneously. Since gear one 9 and the control plate 11, as well as gear two 10 and the movable bar 7 are meshed and connected, gear two 10 drives the movable bar 7 to move forward and backward under the cooperation of the slider 6 and the slide groove, and can drive the clamping structure 13 at the front of the movable bar 7 to move to a suitable position. During the rotation of gear one 9, gear two 10 will also drive the control plate 11 to rotate, which can increase the sliding speed of the movable bar 7, and can increase the stability of the clamping structure 13 after the movable bar 7 is stable.

[0030] according to Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, the front end of the movable bar 7 is fixedly connected with a clamping structure 13, and the clamping structure 13 includes a connecting block 131, a clamping bar 132 and a sponge bar 133. The connecting block 131 is fixedly connected to the front end of the movable bar 7, and the other end of the connecting block 131 is connected to the clamping bar 132. The inner side wall of the clamping bar 132 is fixedly connected with the sponge bar 133, and the inner wall of the sponge bar 133 is in a twill shape. Four connecting blocks 131, four clamping bars 132 and four sponge bars 133 are each provided, and the four clamping bars 132 form a whole circle.

[0031] In a specific embodiment, the clamping strip 132 is arranged according to the circular shape of the profile, which can conveniently clamp and fix the profile to be processed, and the sponge strip 133 can increase the friction between the clamping strip 132 and the profile to avoid the profile from falling during processing.

[0032] according to Figure 7 , Figure 8 and Fig. 9 As shown, a waste collecting unit 14 is arranged in front of the base frame 5, and the waste collecting unit 14 includes a waste collecting frame 141, a pad 142, a guide structure 143 and an extraction hole 144. The waste collecting frame 141 is arranged in front of the base frame 5, and the pad 142 is fixedly connected to the middle position of the inner side wall of the waste collecting frame 141, and the guide structure 143 is arranged at the lower position of the interior of the waste collecting frame 141. The extraction hole 144 is opened through the middle position of the end of the waste collecting frame 141, and the pad 142 is arranged in a semicircular structure, and the pad 142 is symmetrically arranged with respect to the central axis of the waste collecting frame 141, and the guide structure 143 is composed of a rotating rod 1431, a rotating drum 1432 and a noise reduction guide plate 1433. The rotating rod 1431 passes through the front and rear walls of the lower middle part of the waste collecting frame 141, and the rotating drum 1432 is sleeved and installed on the outer wall of the rotating rod 1431. The outer wall of the rotating drum 1432 is fixedly connected with the noise reduction guide plate 1433 at equal intervals. The noise reduction guide plate 1433 is arranged in an arc shape, and the top port of the noise reduction guide plate 1433 is lower than the end port position of the noise reduction guide plate 1433.

[0033] In a specific implementation manner, the pad 142 provides preliminary support for the profile, and cooperates with the external exhaust fan and exhaust pipe through the suction hole 144. When the exhaust fan is working, the air flow rate around the noise reduction guide plate 1433 at the lower part of the waste chip collection frame 141 will be increased. At this time, the noise reduction guide plate 1433 rotates under the rotation of the rotating rod 1431, and the debris generated during the profile processing can be drained into the exhaust pipe to prevent the debris from flying around. Because in the traditional process, the hair dryer and the blow pipe directly absorb the debris, which is easy to generate noise. The use of the noise reduction guide plate can not only drain but also reduce noise.

[0034] according to Figure 1 , Figure 5 and Figure 6As shown, a frame 15 is fixed to one side of the top of the base 1, a hydraulic cylinder 16 is installed in the middle of the top of the frame 15, a hydraulic rod 17 is installed at the output end of the hydraulic cylinder 16, a first driver is installed at the output end of the hydraulic rod 17, a burr removal structure 18 is connected to the first driver, and the burr removal structure 18 includes a screw rod 181, a smooth rod 182, a moving ring 183, a limiting ring 184, a connecting strip 185, a knife strip 186 and a knife body 187, the screw rod 181 is fixedly connected to the smooth rod 182, a moving ring 183 is installed on the outer ring of the screw rod 181, and the screw rod 181 and the smooth rod 182 are connected. The outer rings of the ends of the rods 182 are fixedly connected to the limit rings 184, and the knife strips 186 are rotatably connected to the movable rings 183 and the limit rings 184 respectively through the connecting strips 185. The connecting strips 185 are symmetrically arranged with the central axes of the movable rings 183 and the limit rings 184. The outer wall of the knife strips 186 is fixedly mounted with a knife body 187. The connecting strips 185, the knife strips 186 and the knife body 187 are all arranged at equal angles on the outside of the screw rod 181, and the knife body 187 is arranged in an arc shape as a whole. The top end of the movable ring 183 is rotatably connected to the first driver, and the movable ring 183 is threadedly connected to the screw rod 181.

[0035] In a specific implementation manner, when the hydraulic cylinder 16 is working, it drives the burr removal structure 18 to move up and down as a whole. Under the driving action of the first driver, the moving ring 183 in the burr removal structure 18 will rotate on the screw rod 181. At this time, the connecting strip 185 rotatably connected to the moving ring 183 will change the inclination angle of the connecting strip 185 as the moving ring 183 descends or rises and is subjected to pressure or recovery force. At this point, the knife strip 186 and the knife body 187 will become larger or smaller under the traction of the connecting strip 185, so they can be adjusted according to the size of the profile aperture, and can adapt to different profile apertures. The burr removal structure 18 can only rotate after being connected to an external driving device as a whole, and the internal burrs of the aluminum profile can also be removed through the knife body 187.

[0036] Working principle of the present invention:

[0037] First, connect the driving motor 2 to the external power supply, and then place the circular aluminum profile on the pad 142 inside the waste collection frame 141. At this time, turn on the power switch connecting the support rod 8 and the second driver. At this time, the support rod 8 starts to rotate. During the rotation of the support rod 8, gear 1 9 and gear 2 10 start to rotate. Because gear 1 9 and the control plate 11, and gear 2 10 and the movable bar 7 are all meshed and connected, gear 2 10 drives the movable bar 7 and moves back and forth under the cooperation of the slider 6 and the slide groove, which can drive the clamping structure 13 at the front of the movable bar 7 to move to a suitable position, until the inner wall of the clamping bar 132 in the clamping structure 13 is tightly fitted with the outer wall of the circular aluminum profile. Because there are four clamping bars 132, when the clamping bars 132 are all in place, the circular aluminum profile can be wrapped and fixed in all directions. At this time, turn off the power switch of the second driver;

[0038] Then the above-mentioned entire clamping device is arranged at equal intervals on the driving disk 4, and a plurality of aluminum profiles are fixedly installed according to the above method, and then the hydraulic cylinder 16 is connected to the external power supply, and then the power switch of the hydraulic cylinder 16 is turned on, and then the hydraulic rod 17 drives the burr removal structure 18 to move downward, and at this time, the movable ring 183 in the burr removal structure 18 is driven by the first driver, and the movable ring 183 will rotate on the screw rod 181, and at this time, the connecting strip 185 rotatably connected to the movable ring 183 will change the inclination angle of the connecting strip 185 as the movable ring 183 descends or rises. At this point, the knife strip 186 and the knife body 187 will become larger or smaller under the traction of the connecting strip 185 until the knife strip 186 contacts the inner wall of the profile, and then the power switch of the first driver is turned off. Because the burr removal structure 18 is connected to the external driving device as a whole, the external driving device drives the burr removal structure 18 to rotate as a whole, and the sharp blade of the knife body 187 will remove the internal burrs of the profile;

[0039] Secondly, during the process of removing burrs from the inner hole of the profile, the suction hole 144 cooperates with the external exhaust fan and the exhaust pipe. When the exhaust fan works to absorb, the air flow rate around the noise reduction guide plate 1433 at the lower part of the waste chip collection frame 141 will be increased. At this time, the noise reduction guide plate 1433 rotates under the rotation of the rotating rod 1431, and the debris generated during the profile processing can be drained into the exhaust pipe to prevent the debris from flying around.

[0040] Finally, after the burrs of one profile are removed and the debris is collected, the power switch of the drive motor 2 is turned on. At this time, the shaft 3 drives another group of clamped profiles on the drive disk 4 to the bottom of the burr removal structure 18, and the burrs of the next group of profiles are removed according to the above method, and the overall work efficiency is extremely high.

[0041] Finally, several points should be explained: first, in the drawings of the embodiments disclosed in the present invention, only the structures related to the embodiments disclosed in the present invention are involved, and other structures can refer to the general design. In the absence of conflict, the same embodiment and different embodiments of the present invention can be combined with each other;

[0042] Finally: The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
