Description

Technical Field

[0001] This invention relates to the technical field of profile steel processing, and in particular to the technical field of profile steel polishing machines. Background Technology

[0002] H-beams are an economical and efficient structural material with a more optimized cross-sectional area distribution and a more reasonable strength-to-weight ratio. They are named for their cross-section, which resembles the letter "H". Because all parts of an H-beam are arranged at right angles, it has advantages such as strong bending resistance in all directions, simple construction, cost savings, and light structural weight, and has been widely used.

[0003] Because H-beams are stored in warehouses for extended periods, an oxide layer forms on their surface. Furthermore, the irregular shape of H-beams makes cleaning the inner surface difficult. Currently, manual grinding and polishing are generally used, which is inefficient. Summary of the Invention

[0005] To achieve the above objectives, the present invention proposes a steel profile polishing machine, comprising a feeding conveyor belt, a polishing chamber, and a discharging conveyor belt arranged sequentially. The polishing chamber has openings on both the feeding and discharging sides, and a positioning mechanism is provided at each opening. The positioning mechanism includes positioning frames located on both sides of the polishing chamber, with vertical positioning rollers rotatably mounted on the positioning frames. The two positioning rollers are located on the left and right sides of the steel profile body. A telescopic spring is fixed to the opening, and the end of the telescopic spring is connected to the positioning frame. An inner grinding mechanism is provided inside the polishing chamber, and two surface grinding mechanisms are provided inside the polishing chamber, located on the front and rear sides of the inner grinding mechanism.

Both the upper and lower side plates have racks. A drive gear is provided between the upper and lower side plates. The drive gear meshes with the racks on both sides. The drive gear rotates to drive the upper slide and the lower slide to move towards or away from each other. The top of the upper slide has an upper mounting groove in which the upper polishing roller is rotatably mounted. The bottom of the lower slide has a lower mounting groove in which the lower polishing roller is rotatably mounted.

[0007] Preferably, a double-sided grinding mechanism is installed on the side of the lower side plate near the profile body. The double-sided grinding mechanism includes a double-head grinding motor and a grinding disc. The double-head grinding motor is connected to the lower side plate through a telescopic cylinder. The two ends of the double-head grinding motor are provided with rotating shafts, and two grinding discs are respectively installed on the two rotating shafts.

[0008] Preferably, the grinding disc is equipped with a mounting rod, and the rotating shaft is provided with a slot. The mounting rod is detachably mounted to the grinding disc and the slot.

[0012] The beneficial effects of this invention are as follows: This invention grinds the inner surface of the steel profile by setting an inner grinding mechanism, grinds the surface of the steel profile by a surface grinding mechanism, and grinds the back of the steel profile by a double-sided grinding mechanism, completing the grinding and cleaning of all surfaces in one go, resulting in high work efficiency; by setting the surface grinding mechanism on both sides of the inner grinding mechanism, the steel profile can be positioned during grinding, allowing the inner grinding mechanism to position and grind the web of the steel profile, resulting in good grinding effect; the two surface grinding mechanisms have different surface roughnesses, which can further polish the outer surface of the steel profile during discharge, resulting in good polishing effect; different lengths of grinding rods can be selected according to the size of the steel profile, making it widely applicable.

Then, the telescopic cylinder 7 drives the double-sided grinding mechanism to move closer to the profile, so that the grinding disc comes into contact with the profile. At the same time, the bidirectional screw rotates, driving the inner grinding electric mechanism to move towards the profile, so that the grinding disc comes into contact with the profile, and then the grinding work begins. While grinding, the feeding conveyor belt 1 and the discharging conveyor belt 3 transport the profile forward.
