[0002] Steel profile is a metal material processed by hot rolling or cold bending, with a specific cross-sectional shape and size. It mainly includes hot-rolled steel plates, steel sections and cold-bent thin-walled steel sections. Common types include angle steel, I-beam, channel steel, pipes and other types.

[0003] When processing I-beams and channel steels, they need to be cut and segmented according to specific sizes. The burrs produced on the cross-section after cutting need to be processed by grinding equipment. Most of the existing burr processing equipment is a manually controlled grinder that operates on a single side of the workpiece. After operating one side, the other side of the workpiece is changed to operate.

[0004] The disadvantages of the above processing methods are:

[0005] There are many wing plates in the steel profile section, and the rough edges need to be polished manually and one by one, which is inefficient.

[0006] When the workpiece is large, the operating efficiency during surface grinding is low, which often causes the equipment to be in an idling period, thereby reducing the efficiency of the equipment. In order to solve the above problems, an auxiliary device for processing steel structure profiles is designed. Utility Model Content

[0028] In order to make the technical solution of the present invention more clear and specific to those skilled in the art, the present invention is further described in detail below in conjunction with embodiments and drawings, but the implementation methods of the present invention are not limited thereto.

[0029] like Figure 1-Figure 5As shown, an auxiliary device for processing steel structure profiles provided in this embodiment includes a machine base 1, a bearing mechanism 2 for placing steel structure profiles is rotatably connected to the top of the machine base 1, a moving mechanism 4 is limited and slidably provided in the inner chamber of the machine base 1, and grinding mechanisms 3 for grinding steel structure profiles are installed at both ends of the top of the moving mechanism 4; the bearing mechanism 2 includes a bearing turntable 201, a placement groove 205 for placing steel structure profiles is opened on the top of the bearing turntable 201, and a clamping plate 204 is symmetrically slidably provided in the inner side wall of the placement groove 205; the moving mechanism 4 includes a first moving frame 401 and a second moving frame 402 that are slidably connected to the inner wall of the machine base 1 The first movable frame 401 and the second movable frame 405 are provided with a bidirectional threaded screw 402 running through their inner walls, and a second transmission assembly 403 is fixedly sleeved on the middle part of the bidirectional threaded screw 402; the grinding mechanism 3 comprises a grinding roller group 301 and a grinding disc 302, the grinding roller group 301 is rotatably connected to the U-shaped groove at the top of the first movable frame 401 through a rotating shaft, the grinding roller groups 301 are synchronously driven and connected through the first transmission assembly 303, a second motor 302a is fixedly provided in the U-shaped groove at the top of the second movable frame 405, and the output end of the second motor 302a is detachably mounted on the grinding disc 302 through bolts.

[0030] In the above embodiment, after the steel structure profile is placed in the placement groove 205 through the feeding device, the lengths of the two ends extending out of the placement groove 205 are the same, so that the grinding disc 302 and the grinding roller group 301 can move synchronously and contact the grinding position at the same time. After the grinding is completed, the grinding roller group 301 and the grinding disc 302 are synchronously evacuated from the steel structure profile to the outside, without hindering the supporting turntable 201 from carrying the profile and rotating 180 degrees to change the grinding direction.

[0031] A symmetrical closed cavity is provided inside the carrying turntable 201, and a hydraulic rod 203 and a guide rod 202 are fixed on the inner wall of the closed cavity. The free ends of the hydraulic rod 203 and the guide rod 202 are fixedly connected to the clamping plate 204. The clamping plates 204 on both sides apply pressure through the hydraulic rod 203 to provide stability to the profile during grinding. The guide rod 202 can provide a guide for the clamping plates 204 to move forward and backward to avoid uneven force exerted by the clamping plates 204 on the profile.

[0032] Reverse thread grooves are provided on both sides of the bidirectional threaded screw 402, and a third motor 404 fixed to the bottom of the machine base 1 is installed on one side of the bottom of the second transmission assembly 403. A support seat 6 fixed to the bottom of the machine base 1 is provided on the periphery of the third motor 404. The bidirectional threaded screw 402 and the inner wall of the support seat 6 are rotationally installed through bearing limiters. The bidirectional threaded screw 402 can drive the moving mechanisms 4 on both sides to move synchronously in opposite directions.

[0033] The grinding roller group 301 is composed of 2 large grinding rollers and 4 small grinding rollers. The grinding roller group 301 contacts and grinds the edges of the wing plates and the web plates at the cross section of the steel structure profile. The grinding disc 302 contacts and grinds the outer walls of the wing plates and the web plates at the cross section of the steel structure profile. Usually, at the cross section of the steel profile, the burrs are located at the edges of the wing plates and the web plates. When grinding the edges, the 2 large grinding rollers grind the burrs on the outer edges of the upper and lower wing plates, and the 4 small grinding rollers grind the burrs on the inner edges of the upper and lower wing plates. At the same time, the side walls of the grinding rollers are used to grind the burrs on the edges on both sides of the web plates. After grinding, they are turned around, and the burrs on the outer walls are polished by the grinding disc 302.

[0034] The first transmission assembly 303 is equipped with a first motor 301a fixed on the outer wall of the first mobile frame 401. The top of the support base 6 is fixed with a fourth motor 7, and the output shaft of the fourth motor 7 passes through the top of the base 1 and is connected with the center of the bottom of the carrying turntable 201 by interference fit. The outer wall of the base 1 is also embedded with an operation panel 5.

[0035] The first motor 301a, the second motor 302a, the third motor 404 and the fourth motor 7 are all controlled by a control system in the operation panel 5 and are manually operated to achieve precise operation.

[0036] Working principle of the device: When the device is in use, it is connected to an external power supply, and the cut I-beams, H-beams, channel steels and other types of steel profiles are placed into the placement slot 205 through the feeding equipment, and both ends of the workpiece exceed the same length of the carrying turntable 201.

[0037] The third motor 404 is started through the operation panel 5 to drive the second transmission assembly 403 to drive the bidirectional threaded screw 402 to rotate synchronously, and the bidirectional threaded screw 402 drives the first movable frame 401 and the second movable frame 405, which are threadedly connected at both ends, to move toward each other in the inner wall sliding groove of the machine base 1 until the outer wall of the grinding disc 302 fits with the outer wall of the wing plate and the web of the profile, and the 6 groups of grinding rollers of the grinding roller group 301 are stuck to the edges of the wing plate and the web of the profile, and the first motor 301a and the second motor 301a are started through the operation panel 5. The machine 302a works, driving the grinding roller group 301 to grind the burrs on the edges of the wing plates and the web plates of the profile, and driving the grinding disc 302 to grind the burrs on the vertical surfaces of the outer walls of the wing plates and the web plates. After the front grinding is completed, the bidirectional threaded screw 402 moves the first movable frame 401 and the second movable frame 405 in the opposite direction, and the fourth motor 7 drives the supporting turntable 201 to rotate 180 degrees on the top of the machine base 1 and stop, and the grinding end faces of the profile are exchanged to achieve full coverage grinding of the wing plates and the web plates at the two sections of the profile.

[0038] After the grinding is finished, the first moving frame 401 and the second moving frame 405 are withdrawn again, the hydraulic rod 203 withdraws the clamping of the clamping plate 204 on the profile, and the unloading mechanism takes out the profile to carry out the grinding operation of the next group of profiles.

[0039] The design of the above structure enables the steel structure profile to grind two cutting surfaces simultaneously in the supporting turntable 201. The grinding roller group 301 and the grinding disk 302 achieve full coverage grinding of the profile on the outer wall and edge of the cutting surface wing plate and web plate. After the grinding is completed, the direction of the supporting turntable 201 is quickly turned by the fourth motor 7 to perform the surface changing grinding operation, which not only improves the grinding accuracy but also improves the grinding efficiency.

[0040] The above are only further embodiments of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes within the scope disclosed by the present invention according to the technical solution and concept of the present invention, which fall within the protection scope of the present invention.
