Safe deposit boxes are thought to have originated in Europe. At that time, the safe was just a strong thick wooden box with iron rings. A sample of this ancient wooden box is still preserved in Chichester Cathedral in England. It is 9 feet long, 2 feet high and 2 feet deep. It is made of 2-inch thick wooden boards and has a history of about 65,438+0,000 years. This may be the oldest safe that has survived so far. In medieval European paintings, you can occasionally see a wooden cabinet with a metal edge, which is used to hold gold and silver jewelry. This is the prototype of the safe. Until the beginning of19th century, about 200 years ago, with the growth of social wealth, there was a real market demand for safes, and European manufacturers specializing in locks began to turn to the safe industry. 18 18, the container lock and safe manufacturing factory was established in London. 1825, French FICHE-BAUCHE company was established, and these manufacturers began to manufacture safes. /kloc-In the late 8th century, Carron Co in Scotland and Coalbrookdale in England began to manufacture cast iron boxes and bookcases. This is the beginning of the metal safe, but the tenon technology or integral casting of wood is basically adopted, which is similar to the furniture at that time in appearance and technology, and the lock accuracy is very low.

The main users of early commercial safes were banks, insurance companies, government archives and commercial institutions. The safe is made of cast iron and is completed by riveting and tenoning technology. Cast iron ribs are added to the box and door (door or made separately) to increase strength. The appearance and latch of the safe seemed solid, but the lock and mechanism were relatively simple, so the safe at that time was just some seemingly solid iron boxes, and the thickness of the door panel was generally 1/2 inches (12 mm).

The process of making a safe is very similar to that of making clothes in a tailor's shop. First of all, let's take a look at the flow chart of making a safe:

Steel plate blanking-> sheet metal forming-> welding process-> surface treatment-> assembly-> general inspection-> packaging-> warehousing.

From the above table, we may not have a clear understanding of the production process of safe. Let's know the meaning of each process in detail, so that we can deeply understand the making process of the safe:

Steel plate blanking: As we all know, the raw material of safe is steel plate. Our first process is to cut the bought large steel plate into small pieces with a shearing machine, which is convenient for the next process, just like making clothes. First, cut large pieces of cloth into small squares such as collars and cuffs.

Sheet metal forming: the small plate is processed into various components required by the safe by various machines and equipment such as punching machine, die, bending machine, etc., such as door panel, back panel, bottom panel and various mechanisms of the box. For example, when making clothes, cut small squares of cloth into various initial shapes such as collars and cuffs.

Welding process: welding all kinds of formed plates into a box with a door. Through this process, the initial framework of SAFE has been basically established. Similar to making clothes, sewing machines are used to sew up various small shaped materials to form basic shaped clothes.

Surface treatment: the whole process of fine processing the safe blank through various processes and finally spraying plastic on the surface of the safe. Because the welded safe is rough, we need to polish and remove slag. Because there are rust spots and oil stains on the surface of the safe, phosphating treatment is needed to achieve the purpose of oil removal and rust removal. Because the rough surface of the safe blank is rough, we need to scrape the putty dust off the surface like furniture and polish it smoothly. Finally, high-temperature electrostatic plastic spraying treatment is needed to form paint on the surface. This process is similar to ironing sewn clothes and cutting off extra stitches.

Assembly: Assembly is the process of combining all kinds of locks and accessories that make up the safe to form a complete safe that can be used. If the lock is an electronic password lock, it is called an electronic safe; If the lock adopts a mechanical lock, it is called a mechanical safe; If a fingerprint lock is used, it is called a fingerprint safe. There are many assembly accessories, mainly including casters, locks (door locks, emergency locks and coded locks), operation panels and mechanisms (including door bolts and handles). ), back cover and installation accessories (drawers, flannel, labels, instructions, partitions, etc. ). It's like the final assembly procedure of sewing buttons and labeling clothes.

General inspection: General inspection is the process of checking the quality of the safe, checking whether the produced safe meets the original design requirements of the company, whether there are missing accessories, whether the paint meets the standard requirements, whether it is flexible to use and whether the anti-theft performance is up to standard. This process is very important. If the problem in the safe is not detected, it will flow into the market, causing losses and customer complaints. The general inspection mentioned here is the final inspection of the whole project. In fact, every technological link of the safe needs inspection in the production process, which is called process inspection, and parts in external processing also need inspection, which is called outsourcing inspection. In a word, general inspection is one of the important means to control quality. 、

Packaging and storage: This is the last process of safe production. It is also a very important process to package the safe that has passed the inspection to meet the needs of transportation and storage. Many safes in the market are damaged by paint, and the damage of accessories is often caused by unreasonable packaging and transportation. Therefore, even in the sales terminal, we should pay special attention to the transportation, loading and unloading of products, and give full consideration to ventilation, dryness, rain protection and other conditions when selecting warehouses to avoid the products from being damaged by moisture.
