Common classification
1, According to the type of base, it is divided into two types: dump type and fixed type;
2, according to the type of arm body is divided into: sliding type and card type two;
3, according to the door cover position is divided into full cover (straight bend, straight arm) general cover 18 percent, half cover (bend, bend arm) cover 9 percent, hidden (big bend, big bend) door all hidden inside;
4, according to the style of the hinge development stage is divided into: a force hinge, two force hinge, hydraulic buffer hinge, touch self-opening hinge;
5, according to the Angle of the door hinge: generally used 95-110 degrees, special 25 degrees, 30 degrees, 45 degrees, 135 degrees, 165 degrees, 180 degrees and so on;
6, according to the type of hinges are divided into: ordinary one, two force hinges, short arm hinges, 26 cup micro hinges, marble hinges, aluminum frame door hinges, special Angle hinges, glass hinges, rebound hinges, American hinges, damping hinges, thick door hinges and so on.
Maintenance and maintenance:
1. Wipe gently with a dry soft cloth, do not use chemical detergent or acidic liquid cleaning, if it is found that the surface is difficult to remove black spots, can be wiped with a little kerosene;
2. The use of a long time to make a sound is a normal phenomenon, in order to ensure that the pulley durable smooth silent, every 2-3 months can be regularly added lubricating oil maintenance.
3. Heavy objects and sharp instruments should be prevented from hitting and scratching.
4. Avoid pulling hard during handling and damaging the hardware at the connection of furniture.
Product Parameters
The hinge production process of our factory is mainly as follows:
First, material preparation
The first step in making a hinge is to prepare the materials. The most common alloy material is steel, but some hinges use materials such as copper, aluminum, zinc and stainless steel. First of all, it is necessary to select the appropriate material according to the required specifications and quantities, and determine its appropriate thickness and hardness.
Two, cold heading processing
In the process of manufacturing hinges, cold heading processing is usually unavoidable. This process creates the shaft and hinge of the hinge by pressing a metal material into a perforated rod. In this process, the metal material is highly compressed, and this compression can increase the hardness and strength of the metal.
Third, heat treatment
Heat treatment is an important step in the manufacture of high quality hinge. In this process, the material is heated to change its mechanical and physical properties and make it stronger and more durable. Heat treatment can also change the color and appearance of the hinge, making it more beautiful and durable.
Fourth, surface treatment
Surface treatment is the final step in hinge manufacturing, the purpose is to make the hinge better adapt to the environment, enhance its corrosion resistance and wear resistance. Common surface treatment methods include galvanizing, anodizing, painting and polishing. These surface treatments can make the hinge more beautiful and prevent corrosion and damage.
1. Spring hinges
Mainly used for cabinet doors, wardrobe doors, it generally requires a plate thickness of 18-20mm. From the material points, can be divided into: galvanized iron, zinc alloy. From the performance points, can be divided into: need to punch holes, do not need to punch two kinds of holes. No hole is what we call a bridge hinge. Bridge hinge looks like a bridge, so it is commonly known as bridge hinge. It is characterized by no need to drill holes in the door panel and is not limited by style. Sizes: small, medium, large. The need to make holes is now commonly used in the spring hinge on the cabinet door. Its characteristics: the door panel must be perforated, the style of the door is limited by hinges, the door will not be blown open after closing, and there is no need to install various spiders. Specifications are: &26, &35. Among them, there are two kinds of directional hinges which can be released and orientation-free hinges which cannot be released. For example, the 303 series of Longsheng hinges is a tipping directional hinge, and the 204 series is a non-unloading spring hinge that can be divided from the shape: The full cover (or straight arm, straight bend) half cover (or bend arm, middle bend) inside (or big bend, big bend) hinge is attached with adjusting screws, which can adjust the height and thickness of the plate up and down, left and right. The distance between the two screws fixing holes on the side of the hole is generally 32mm, and the distance between the diameter edge and the two sides of the plate is 4mm (drawing). In addition, there are various special specifications of spring hinges, such as: 45 degree Angle hinges on the inside, 135 degree Angle hinges on the outside, and 175 degree Angle hinges.
On the difference between the three kinds of hinges of right Angle (straight arm), half bend (half bend), and big bend (big bend) :
Right-angle hinges allow the door to completely cover the side panels;
Semi-curved hinges allow the door panel to cover part of the side panel;
Large curved hinges allow the door panel to be parallel to the side panel;
2. Door hinges
It is also divided into ordinary type and bearing type, ordinary type has already talked about, now focus on bearing type. Bearing type from the material can be divided into copper, stainless steel. From the specifications: 100X75 125X75 150X90 100X100 125X100 150X100 thickness of 2.5mm, 3mm bearings have two bearings, four bearings. From the point of view of consumption, the selection of copper bearing hinges is more, because of its beautiful style, bright, moderate price, and equipped with screws.
3. Electromechanical cabinet hinges
It includes nylon hinges with high wear resistance; Corrosion resistant, high strength zinc alloy hinges; Corrosion resistance, oxidation resistance, high strength stainless steel hinges, often used in mechanical and electrical cabinet doors, mechanical equipment operating boxes and other products.
4. Heavy hinges
Due to the particularity of the installation position, the requirements for hinges are also very large, the general size is more than 150MM, the bearing force is large, the shape structure is in line with the special structure of the cabinet door, often used in cold storage, freezers and other large doors, mostly zinc alloy material.
5. Special-shaped hinges
The door opening Angle is large, and it is also widely used in daily use.
6. Other hinges
There are table hinges, flip door hinges, glass hinges. Glass hinges are used to install frameless glass cabinet doors, requiring a glass thickness of no more than 5-6mm. The pattern has holes and has all the properties of spring hinges. No holes are made for magnetic suction type and upper and lower top mounting type, such as Pepsi, magnetic glass hinges, etc.
