Cutting and demolition of concrete and post-maintenance of saw blade tools

2022-04-11

For concrete cutting and demolition, the most important thing is its cutting equipment - cutting machine. With the development of the current industry, in terms of cutting, people have gradually improved its precision and quality, and the requirements for cutting machines are also increasing, prompting the production of various cutting machines. It is composed of six parts: table, horizontal cutting car, frame and electronic control system, mainly for cutting concrete components, walls, pavements, etc.


In order to improve the cutting performance and prolong its service life in the later use process. In the process of using, you also need to do the following work:

1. The shaft of the lever should be intact, flexible and reliable to rotate, and should be locked with a nut after being assembled with the lever. In order to protect the performance of the cutting machine, be careful not to use it in places with explosive dust. After replacing the cutting blade, check whether there is obvious vibration in the trial operation, and then use it after confirming that the operation is normal.

2. The clamping device should be flexible in operation and reliable in clamping. The handwheel, lead screw, nut, etc. should be in good condition. Note that the lever should have sufficient strength and rigidity to keep lifting freely after all parts are installed. When using the cutting machine, the rotation direction should avoid the nearby staff as much as possible, and the cut material should not protrude into the sidewalk.

3. When replacing the concrete cutting blade, the power supply must be cut off. The newly installed cutting blade must meet the equipment requirements, and the cutting blade with quality problems shall not be installed. When installing, follow the installer. The power supply should be cut off after use, and the operation box or switch must be intact and grounded.

4. In addition, the protective cover of the transmission device must be safe and reliable, and can block the fragments that fly out after the cutting blade is broken. The baffle at the end should be firmly installed on the cover, and it is strictly forbidden to remove it during work. Jiangsu concrete cutting reminds that when the operator manipulates the handle for cutting motion, the force should be uniform and stable, and do not use too much force, so as to avoid overloading and cracking of the cutting blade.

Maintenance of concrete cutting machine The cutting machine realizes large-volume forming of aerated concrete, flexible and diverse dimensions, high precision, and large-scale mechanized production. The operating condition of the cutting machine directly affects the cutting dimensional accuracy. Therefore, the transmission device and steel wire of the cutting machine should be strengthened. Repair and maintenance of equipment and facilities such as positioning devices. In the process of normal use, the concrete cutting machine should be used and maintained reasonably, so as to prolong the life of the cutting machine.
