By arranging a handle above the angle grinder of the device, a worker can move the angle grinder by means of the handle, and because the handle can slide in the fixing plate, the cooperation between the main magnet and the auxiliary magnet can effectively prevent the vibration generated after the angle grinder is started from being transmitted to the handle, so as to prevent the worker's hands from being numb due to the vibration during long-term grinding, and to prevent the angle grinder from slipping out of the hand and causing danger. The size of the sleeve provided in the device can be adjusted by a screw rod, so that the device can adapt to angle grinders of different models, thereby improving its applicability.

Description

Technical Field

[0001] The invention relates to the field of steel casting, in particular to a handheld continuous casting slab burr cleaning device. Background Art

[0002] After continuous casting, the slab is cut into sections of a certain length by a flame cutting machine and then put on the roller line. Because there is a steel slag attached to the bottom of the cross section of the steel slab during flame cutting, it is called slab burr. This burr is very hard. If it is not removed or not removed cleanly, it may be embedded in the steel plate during subsequent rolling, resulting in unqualified steel plate quality and waste products. At the same time, it causes great damage to the rolling roller, which directly affects production efficiency and production cost. At present, handheld angle grinders are usually used to clean the burrs of the slab, but because the angle grinder will vibrate when in use, after long-term use, the hands of the staff are easily numb, which can easily cause the angle grinder to slip out of the hand, which is very dangerous.

[0021] See also Figure 1-5 It is a schematic diagram of the structure of the present invention, a convenient handheld continuous casting slab burr cleaning device, including an angle grinder 1, angle grinder 1, also known as a grinder or disc grinder, is a grinding tool used for cutting and grinding glass fiber reinforced plastics. Angle grinder is a portable electric tool that uses glass fiber reinforced plastics for cutting and grinding, and is mainly used for cutting, grinding and brushing metals and stones, etc. When in use, it only needs to be connected to an external power supply, and its internal motor can drive the grinding wheel to rotate to grind the burrs on its slab. The outer wall of the angle grinder 1 is sleeved with a collar 2, and a connecting rod 3 is installed on the upper wall of the collar 2. A fixed plate 4 is installed on the side wall of the connecting rod 3. A slide groove 5 is opened on the side wall of the fixed plate 4. A main magnet 6 is slidably installed on the inner wall of the slide groove 5, and a handle 7 is installed on the side wall of the main magnet 6. The main magnet 6 can slide up and down in its slide groove 5 to prevent the vibration generated by the angle grinder 1 during use from being transmitted to the handle 7. The main magnet 6 includes a connecting block of four magnets and a fixed magnet;

There are four auxiliary magnets 10, and the four auxiliary magnets 10 are respectively arranged on the upper side, lower side, left side and right side of the main magnet 6. The magnetic poles of the four auxiliary magnets 10 close to the main magnet 6 are the same as the magnetic poles on the outside of the main magnet 6. The main magnet 6 and the auxiliary magnets 10 repel each other with the same polarity, so that the main magnet 6 is suspended between the four auxiliary magnets 10. The side walls of 10 are all installed with connecting blocks 11, and the side walls of the connecting blocks 11 are provided with slots 12. Four bolts 9 are respectively inserted into the four slots 12, and the bolts 9 can rotate in the slots 12. Springs are installed on the left and right sides of the main magnet 6, and the springs are fitted and connected to the side walls of the fixing plate 4. The positions of the four auxiliary magnets 10 in their slide grooves 5 can be adjusted by the four bolts 9 to avoid vibration from being transmitted to the handle 7. The bolts 9 can rotate in the slots 12 so that the bolts 9 can adjust the positions of the auxiliary magnets 10, but the auxiliary magnets 10 will not rotate with the bolts 9.

[0023] A cross bar 13 is installed on the side wall of the connecting rod 3, and a pressure plate 14 is installed on the upper wall of the cross bar 13. When the staff holds the device to grind burrs, they can hold the handle 7 with one hand and press the pressure plate 14 with the other hand to apply downward pressure to the device to achieve a better grinding effect. One end of a telescopic rod 15 is installed on the lower wall of the cross bar 13, and the other end of the telescopic rod 15 is in contact with the upper wall of the angle grinder 1. A screw is provided on one side of the telescopic rod 15, and the screw can fix the length of the telescopic rod 15.
