Description

Technical Field

[0001] This utility model relates to the field of steel structure processing technology, and specifically to an automatic slag cleaning device for the main weld of H-beams, particularly an automatic slag cleaning device for the main weld of H-beams that can greatly improve the processing efficiency of steel structures and reduce labor intensity. Background Technology

[0002] H-beams are an economical and efficient structural steel profile with an optimized cross-sectional area distribution and a more reasonable strength-to-weight ratio. They are named for their cross-section resembling the letter "H". Because all parts of an H-beam are arranged at right angles, it possesses advantages such as strong bending resistance in all directions, simple construction, cost savings, and lightweight structure, leading to its widespread use. The integrated welding and straightening machine is currently the equipment used for producing H-beams. The main welds of H-beams are welded using submerged arc welding. After welding, the flux from the submerged arc welding solidifies on the weld surface, forming weld slag. Currently, most integrated welding and straightening machines on the market lack slag cleaning devices. Slag removal is typically done manually using a hand-held pneumatic chisel or shovel, which is slow, time-consuming, and labor-intensive, making it inconvenient for cleaning.

[0003] Therefore, developing a device capable of automatically cleaning welding slag is of great practical significance. Utility Model Content

[0032] The structure of this utility model will be further described below with reference to the accompanying drawings and specific embodiments, but this is not intended to limit the utility model.

[0033] Example 1

[0034] An automatic slag removal device for the main weld of H-beams, such as Figure 1 As shown, it includes a slag cleaning mechanism 100 and a distance adjustment mechanism 200 fixedly connected to the slag cleaning mechanism 100 and used to drive the slag cleaning mechanism 100 to slide.

The slag cleaning motor 102 is fixed on the slag cleaning base 101. A deep groove ball bearing 105 is installed on the slag cleaning base 101. The turntable shaft is inserted and fixed on the deep groove ball bearing 105. A driven gear 106 and the turntable 106 are respectively mounted on the turntable shaft. The slag cleaning motor 102 and the turntable 106 are located on opposite sides of the slag cleaning base 101. The slag cleaning base 101 has openings for the slag cleaning motor 102. The drive shaft of 02 passes through the through hole, and the drive shaft penetrates the slag cleaning base 101 through the through hole and is fixed with the drive gear 103. The drive gear 103 meshes with the driven gear 106. One end of the rocker arm 107 is fixed on the turntable 106, and the other end of the rocker arm 107 is fixedly connected to the impact shaft 109 through the shaft screw 108. The impact shaft 109 is arranged in the slide groove 110 fixed on the slag cleaning base 101 and the impact shaft 109 can slide along the arrangement direction of the slide groove 110. A tube groove 111 is provided on one side of the slide groove 110 and the tube groove 111 is fixed on the slag cleaning base 101. A clamp 112 matching the tube groove 111 is fixed on the tube groove 111.

[0036] Distance adjustment mechanism 200 Figure 4 and 5 As shown, the device includes a distance adjustment base 201, with a distance adjustment motor 203 fixed to one end of the distance adjustment base 201 (the distance adjustment motor 203 is fixed to the distance adjustment base 201 via a motor support 204). Two linear guide rails 209 are fixed to both sides of the distance adjustment base 201. A ball screw transmission mechanism is arranged between the two guide rails 209 and fixed to the distance adjustment base 201. A guide rail slide 210 is slidably connected to the guide rails 209. The ball screw transmission mechanism includes a coupling 211, a ball screw 207, and a screw slide 208 threadedly connected to the ball screw 207. The two ends of the ball screw 207 are respectively connected to screw support I 205 and screw support II. 206 is fixed on the distance adjustment base 201. The ball screw 207 and the drive shaft of the distance adjustment motor 203 are coaxially connected through the coupling 211. The distance adjustment motor 203 drives the ball screw transmission mechanism, i.e., drives the guide rail slide 210 to slide along the guide rail 209. The welding slag cleaning base 101 is simultaneously fixedly connected to the screw slide 208 and the two guide rail slides 210. A clamp 202 is fixed on the side of the distance adjustment base 201 away from the ball screw transmission mechanism.

[0037] The application of the above-mentioned automatic slag cleaning device for the main weld of H-beams is as follows: Figure 1 As shown, it is used in conjunction with the welding and straightening integrated machine 300 to automatically clean the slag from the main weld of H-beam 400. The distance adjustment mechanism can drive the slag cleaning mechanism to move linearly, thereby adjusting the position of the slag cleaning mechanism to adapt to H-beams with different cross-sectional dimensions.

[0038] The operating procedure of the welding slag cleaning mechanism 100 is as follows:

[0039] The slag cleaning motor 102 is activated, which drives the drive gear 103 to rotate. The drive gear 103 drives the driven gear 104 to rotate. The driven gear 104 drives the turntable 106 mounted on the deep groove ball bearing 105 to rotate. The turntable 106 drives one end of the rocker arm 107 connected to it to rotate circumferentially. The other end of the rocker arm 107 is connected to the impact shaft 109 through the shaft screw 108. The rocker arm 107 drives the impact shaft 109 to move up and down along the slide groove 110. With the continuous welding of the H-beam weld, the impact shaft strikes the weld slag formed on the weld surface at a high frequency to achieve the function of breaking the weld slag. At the same time, the tube groove 111 can be connected to the vacuum hose of a negative pressure vacuum cleaner and fixed by the clamp 112 to achieve the function of cleaning the weld slag.

[0040] The operating procedure for the distance adjustment mechanism 200 is as follows:

[0041] The distance adjustment mechanism 200 is installed on the welding and straightening integrated machine 300 via the clamp 202. When the distance adjustment motor 203 is activated, it drives the ball screw 207 to rotate via the coupling 211. The rotation of the ball screw 207 is converted into the linear motion of the screw slide 208, which in turn drives the welding slag cleaning mechanism 100 installed on the screw slide 208 and the guide rail slide 210 to move linearly, thereby achieving the purpose of adjusting the distance between the workpiece and the workpiece.

[0042] Verification has shown that the automatic slag removal device for the main weld of H-beams of this invention has a reasonable structural design. Through the cooperation of the slag removal motor, slag removal transmission mechanism, turntable, rocker arm, and impact shaft, the impact shaft is driven to reciprocate, striking the H-beams and causing the slag on them to fall off, thus achieving slag removal. The distance adjustment mechanism allows for adjustment of the position of the slag removal mechanism to clean the entire main weld, achieving mechanized slag removal with high work efficiency and significantly reducing manual labor. It can be used in conjunction with existing welding and straightening integrated machines to transform H-beam processing lines at a low cost and greatly improve the work efficiency of the production line, showing good application prospects.
