Description

Technical Field

[0001] The present application relates to the technical field of H-beam processing equipment, and in particular to an H-beam grinding equipment. Background Art

[0002] H-shaped steel is a type of steel named after its cross-section which resembles the letter "H". It has a more reasonably optimized cross-sectional area, and therefore has the advantages of strong bending resistance but light structural weight. It is widely used in steel structures, mechanical engineering and other fields.

[0003] In the production of H-beam, the web and wing are usually welded together. During the welding process, welding slag, oxides and other impurities will be formed at the welding position, which usually need to be polished. The relevant Chinese invention patent document with publication number CN112440177A discloses an H-beam R angle grinding device, including a lifting arm and a sliding mechanism. The lifting arm is equipped with a grinding wheel. After the H-beam is placed on the workbench, the R angle of the H-beam, that is, the welding place between the web and the wing, can be polished and cleaned by the grinding wheel to remove impurities.

[0004] Although the H-shaped steel can be ground in the above scheme, impurities such as welding slag generated by grinding are retained on the H-shaped steel, and need to be cleaned up later, which is troublesome. Summary of the invention

[0005] In order to clean the residue after grinding, the present application provides an H-beam grinding device.

[0006] The present application provides an H-beam grinding device, which adopts the following technical solution:

After the H-shaped steel 15 is placed on the support frame 13, the power source 14 drives the support frame 13 to slide on the workbench 1, and transports the H-shaped steel 15 to the bottom of the mounting frame 2. Then the lifting member 3 drives the mounting frame 2 to move downward, so that the grinding assembly 6 can grind the H-shaped steel 15. After grinding, the support frame 13 is slid out through the power source 14.

A connecting tube 4 is mounted on the mounting frame 2, and a driving member 5 for driving the connecting tube 4 to reciprocate along the length direction of the mounting frame 2 is also mounted on the mounting frame 2. The driving member 5 is a screw rod 51 rotatably connected between the two opposite short rods 22, and a motor 52 mounted on one of the short rods 22. The screw rod 51 and the motor 52 are connected, and the connecting tube 4 is threadedly connected to the screw rod 51. The connecting tube 4 is driven to reciprocate by the screw rod 51.

[0035] Reference Figure 2 and Figure 3 , a grinding assembly 6, a cleaning assembly 7 and a collection frame 8 are sequentially mounted on the connecting tube 4. The grinding assembly 6 is used to grind the H-shaped steel 15, and the cleaning assembly 7 is used to sweep the residue generated by grinding into the collection frame 8. The grinding assembly 6 includes a crossbar 61 mounted on the side wall of the connecting tube 4. The crossbar 61 is horizontally arranged, and the length direction of the crossbar 61 is perpendicular to the length direction of the screw 51. The two ends of the crossbar 61 are rotatably connected to a rotating tube 62, and the ends of the rotating tube 62 are fixedly connected to a grinding wheel 63. The distance between the two grinding wheels 63 is the distance between the two wing plates of the H-shaped steel 15. A first gear 64 is coaxially fixed on the outer wall of the rotating tube 62, and a first rack 65 is fixed on the upper surface of the long rod 21. The first gear 64 and the first rack 65 are meshed. When the screw 51 rotates to drive the connecting tube 4 to move, the grinding wheel 63 can be driven to rotate to grind the welding part of the H-shaped steel 15.

[0036] One end of the connecting tube 4 is connected to the inner wall of the collecting frame 8, and the connecting tube 4 moves with the collecting frame 8 synchronously. The cleaning assembly 7 is located between the grinding assembly 6 and the collecting frame 8. The connecting tube 4 is symmetrically fixed with extension rods 9 on both sides, and the cleaning assembly 7 includes a rotating rod 71 that is rotatably connected to the extension rod 9 by bearings or the like. The rotating rod 71 is vertically arranged, and a scraper bar 72 is evenly fixed on the side wall of the lower end of the rotating rod 71. The scraper bar 72 is made of elastic plastic material. A second gear 73 is coaxially mounted on the side wall of the rotating rod 71, and a second rack 74 is mounted on the side wall opposite to the long rod 21. The second gear 73 and the second rack 74 are meshed with each other. When the connecting tube 4 moves, the rotating rod 71 rotates, and the residue can be swept into the collecting frame 8 through the scraper bar 72.
