There are only a few families who can decorate their homes for a lifetime, and the cost of decoration is a relatively large proportion of household consumption. Therefore, it is understandable to save money. However, in the decoration, the owners should know that some of them cannot be saved, otherwise they will have a great influence on the future life. >>>Related Links: Save money to decorate 10 big money to save home decoration The province’s money is mainly reflected in the following aspects (1) Ensure the quality of hidden projects Concealed works refer to projects that need to be covered or covered by foundations, electrical pipelines, and water supply and heating pipelines. Since concealed projects are concealed, if quality problems occur, they must be re-covered and covered up. This can result in very large losses such as rework. In order to avoid waste of resources and loss of both parties, ensure the quality of the project and the successful completion of the project. Before the covert project is concealed, the contractor shall be notified of the inspection, and if the contractor has passed the inspection, the concealed project may be carried out. 1) Money spent on indoor electrical materials cannot be saved The installation of electrical circuits is the most vulnerable to potential safety problems, and once the electrical circuit is hidden, it is not easily repaired. Therefore, it is very important to ensure the high quality of electrical materials. Household electrical materials generally include: leakage protectors, wires, switches, sockets, wiring ducts, etc. These materials are best used in the country recommended brand-name products, and must obtain a product certification at the time of purchase. In the electrical installation, please supervise the supervision company or relevant experts to supervise to ensure that the installation quality meets the requirements of the national regulations. 2) The money for the sewer system cannot be saved Water and fire are ruthless. Once a problem occurs in the waterway, it will not only cause economic losses to the family, but will also affect the tenants downstairs. Therefore, the money in the waterway cannot be saved. Valves and taps are used every day, spending more than a hundred dollars, or at least buying domestic brand-name goods. Qualified products for water pipes and fittings can bring you the convenience of life and eliminate the trouble of running away. 3) Hardware accessories for doors and windows and furniture cannot be saved The door lock must be free to open and close, and the spring force should be better, otherwise it may cause an embarrassing situation where the door is difficult to enter. Drawer rails are of good quality to ensure that drawers are pulled flexibly. In the same way, the quality of handles cannot be ignored. Do not use hinges for furniture cabinet doors and apply branded hinges. 4) Money for waterproof materials cannot be saved. Poor waterproof materials not only do not have a good waterproof effect, but also contain a large number of harmful substances, so this money can not be saved. (2) Choose and buy green decorative materials One of the biggest hidden dangers of furniture decoration is the harmful substances volatilized from decorative materials. This is an invisible killer. The purchase of non-environmentally friendly decorative materials will cause great damage to the physical and mental health of themselves and their families, so they cannot be purchased to save money. Those poor quality non-environmental materials. Can not save the place furniture decoration switch home decoration company drawer cabinet door decoration home 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.
