Cabinets need hinges to connect the door and the cabinet body. Therefore, the quality of the hinges and the installation are particularly important. I believe many people are worried about the installation of the door hinges . So, the following editors will share the classification of cabinet door hinges and the hinge installation skills.
1. Classification of cabinet door hinges
1. Pipe hinge
The pipe hinge is called a spring hinge, which is generally used in the connection of furniture door panels, and the adjustment is very convenient. It is characterized by the opening angle of the cabinet door according to the space. In addition to the ninety degree angle, other angles have corresponding hinges to match, so that the cabinet door has a certain degree of extension.
4. Hydraulic hinge
Hydraulic hinges are generally used in door hinges for furniture such as bookcases, TV cabinets, cupboards, wine cabinets, storage cabinets and other furniture. It has passed the hydraulic buffer technology, so that when the door opening is less than sixty degrees, it will automatically close slowly. Even if you close the door vigorously, it can make the door close slowly, which can effectively prevent children from getting their hands caught.
The above is about the classification of cabinet door hinges . You can understand it. I believe it can help. Choose the appropriate hinge according to the needs of use. Then we will learn the hinge installation skills together.
2. Hinge installation skills
1. Minimum clearance
The minimum clearance refers to the minimum distance on the side of the door when the door is opened. This minimum clearance is determined by the thickness of the door and the type of hinge. If the door edge is rounded, the minimum clearance needs to be reduced, and the clearance of different hinges is different
2. The minimum clearance of the half-cover door
If two doors use a side panel at the same time, the total clearance is required to be twice the minimum clearance, so that the two doors can be opened at the same time.
3. C distance
The C distance refers to the distance between the edge of the door and the hole of the hinge cup. The maximum size of each hinge is C, and the models of different hinges are different. The larger the C distance, the smaller the minimum gap.
4. Door coverage distance
The door coverage distance refers to the distance that the door covers the side panel. This distance must be controlled during installation and can be freely opened.
5. The number of hinges required for each door
The width, height, and material quality of the doors all determine the number of links required for each door. Because each door is different, it is necessary to install the appropriate number of hinges according to the situation. For stability reasons, the distance between the hinges should be as large as possible, which is better.
Editor's summary: The above is the classification of cabinet door hinges and the knowledge of hinge installation skills that I have shared with you. I hope to help everyone. In fact, the installation of the hinge is not a difficult thing, mainly due to the size of the hinge installation and the details of the installation.

Graphite Electrode, mainly in petroleum coke, needle coke as raw material, coal tar pitch as a binder, calcined, ingredients, mixed kneading, pressure, roasting, graphitization, machining and made in the arc furnace in the form of arc The energy can be divided into ordinary power Graphite electrode, High Power Graphite Electrode and Ultra High Power Graphite Electrode according to its quality index.
Graphite electrode transport
1, graphite electrode in the long-distance transport to be covered with anti-rain Pengbu.
2, with lifting machinery unloading wooden box packaging electrodes, you must use the wire rope, not directly hook the electrode steel packing belt for lifting.
3, in order to protect the electrode end and thread, not directly with hook hook electrode hole hanging electrode.
4, loading and unloading joints box, you should gently take to prevent damage to the thread.
Second, the graphite electrode storage
1, the electrode should be stored in a clean, dry place; temporarily do not use the electrode and connector, do not remove the packaging, to prevent dust, debris fall into the thread or electrode hole, affecting product docking accuracy.
2, open field stacking electrodes, must be covered with rain pants. In the case of
3, the electrode in the Treasury storage to be placed neatly, the electrode stack on both sides to pad well, to prevent the cartoons.
4, bulk electrode stacking height is usually not more than 2.8 meters, the height of the box electrode should not be more than 4 layers.
5, the temperature of the place where the joints should be stored should not be too high to prevent the asphaltene joint bolt melting.
Third, the graphite electrode connection operation
1, by the wet electrode, before use to dry.
2, remove the spare electrode hole on the foam protective cap, check the electrode hole thread is complete.
3, with no oil and water compressed air cleaning spare electrode surface and hole thread; to avoid the use of wire or metal brush cloth cleaning.
4. Do not touch the threads in the electrode holes where the joint is carefully screwed into one end of the backup electrode (it is not recommended to insert the connector directly into the electrode that is replaced on the furnace).
5, the electrode spreader (recommended the use of graphite material spreader) screw into the other side of the electrode electrode electrode hole.
6, lifting the electrode, the mat soft objects to the bottom of the alternate electrode assembly to prevent the ground to break the joints; with a hook into the spreader after the lifting ring, lifting the electrode to be smooth, to prevent the electrode from the B-loose Off or collide with other fixtures.
7, the spare electrode hanging to the top of the electrode to be connected to the electrode hole slowly after the fall; rotating the backup electrode, so that the screw hook and the electrode with the rotation down; in the two electrode end distance 10-20mm, again with compressed air Clean the two ends of the electrode and the exposed parts of the joint; in the final complete discharge of the electrode, not too much, or because of violent collision, will lead to electrode holes and joints of the thread damage.
8. Tighten the backup electrode with a torque wrench until the ends of the two electrodes are in close contact (the correct connection of the electrode and the connector is less than 0.05 mm).
Fourth, the graphite electrode in the use of the precautions
1, the electrode holder should be caught in the top of the cord outside the cordon, otherwise easily lead to electrode break. The contact surface of the gripper and the electrode should always be cleaned to maintain good contact with the electrode, and the gripper cooling water jacket should be kept leaking. In the case of
2, the electrode connection found cracks exist to identify the cause, to eliminate the gap before use.
3, connecting the electrode, found that the phenomenon of joint peeling off, to fill the joints and then connect the bolt.
4, the electrode should be used vertically, to avoid tilting operation, in particular, can not be connected to a group of electrodes placed horizontally, so as not to break.
5, to the furnace into the charge, the bulk material should be installed near the bottom of the furnace to reduce the collapse of the large pieces of charge impact electrode.
6, smelting, should avoid a large number of insulation material stacked in the electrode just below, so as not to affect the use of electrodes, or even electrode break.
7, the electrode in the rise or fall, should avoid touching the lid, resulting in electrode damage.
· 8, in the smelting site, to avoid slag splashing to the site of the electrode or connector threaded buckle, damage the thread accuracy.
