Office desk and chair daily maintenance
1. When using desks and chairs on a daily basis, the desk surface will inevitably become dusty. When removing dust, use a feather duster to clean the dust first, and then wipe it clean with a rag.
2. Everyday cleaning rags for office desks and chairs should be cleaned with water-free clean rags moistened with water, the rags should be relatively soft, try not to use too hard or rough cloth or unclean cloth to wipe, so that Effectively prevent the desk surface from being scratched or being contaminated again.
Repair and maintenance of desks and chairs
After long-term use of desks and chairs, the desktop usually has a lot of scratches, scratches or scratches. Don't worry if you encounter this situation. You only need to send it to the original factory for after-sales service. Like new products, of course, the best advantage of this is that it saves a lot of repetitive office furniture costs, saving the company's operating costs.
If you find flaws such as cracks on the desk or chair, or damage during use, it is best to choose to repair. You can contact the manufacturer's after-sales service department. If you are satisfied with the small problem, let them send professional maintenance personnel to repair it. Difficult to solve the problem, but directly sent back to the manufacturer, to be used after the manufacturer repaired.
Desk brightness maintenance
At present, office furniture looks shiny and bright, but long-term use will cause desks and chairs to lose their luster. At this time, if you want to maintain the glossiness of office furniture, use the current special furniture spray and cleaning and maintenance agents. A variety of furniture care products. Before using the furniture spray wax and cleaning and maintenance agent, shake it first, then hold the spray can, and then spray it quietly in the center of about 15 cm apart with a dry rag, so that you can wipe the furniture again, you can play a good cleaning Maintenance effect.
Maintaining furniture is not a simple matter. If some desks and chairs have cloth materials, such as office chairs, cushions, backrests, and other furniture parts, the general method of daily cleaning and maintenance will certainly not work. This is to use clean carpets. The cleaning and maintenance agent to maintain this desk and chair. First use a vacuum cleaner to remove the surface dust, then spray a little carpet cleaner on a damp cloth and wipe it off.
Plate rolling is a process of continuous three-point bending of sheet metal using a plate rolling machine. The equipment puts the sheet material between the upper and lower work rolls when rolling. The upper roller is raised and lowered vertically, and the two lower rollers rotate and move horizontally relative to the axis of the upper roller. When the upper roll descends, the plate is plastically deformed and bent between the upper and lower work rolls. The continuous rotation of the bottom roller drives the steel plate to advance and retreat through the friction between the plate and the roller to complete the coiling.
1. Pre-bending. When the plate is rolled, there is a length at both ends of the plate that does not bend because it does not touch the upper roller. It is called the remaining straight edge. In the process, the minimum force arm at which the plate starts to bend is called the theoretical remaining straight edge. The bending form (symmetrical bending, asymmetrical bending) is related.
2. Centering. The purpose of centering is to make the generatrix of the workpiece parallel to the roller axis to prevent skew.
3. Roll round. Rolling is the main process of product forming, which is divided into two types: one-time feed and multiple feeds. Multiple feeds are commonly used for rolling thick plates. The number of feeds depends on the technological constraints (such as the maximum allowable deformation during cold rolling) and equipment constraints (such as non-slip conditions and power conditions). When the rebound of the cold coil is significant, a certain amount of overcoiling must be added.
4. Straightening round. The purpose of rounding is to make the curvature of the entire circle as uniform as possible to ensure product quality. The general rounding process is divided into three steps:
(1) Load: According to experience or calculation, adjust the work roll to the position of the required maximum correction curvature.
(2) Rounding: Roll the roller 1 to 2 turns under the corrected curvature to make the entire curling rate uniform.
(3) Unloading: gradually unload the load, so that the workpiece is rolled several times under the gradually reduced correction load.
