Floor spring installation legend

A. Draw a line so that the center of the floor spring shaft coincides with the door clamp shaft. B. Make a hole on the ground according to the instructions and the actual object. The size of the hole must be tightly matched with the floor spring shell and cannot be loosened. C. Put the floor spring into the open Straighten the inside of a good hole. D. Lift up the door leaf with the door clamp, insert the shaft of the floor spring into the shaft hole of the door leaf. E. Adjust the screws in the three directions of the floor spring. Keep the door leaf vertical, and rotate the axis up and down. Coincidence. F. Adjust the speed of closing the door. G. Cover the floor spring and decorate the floor spring. The installation accuracy of the floor spring has a great influence on its service life. The quality defects of the floor spring must include: oil leakage of the body and eccentricity of the ground axis. The oil leakage of the main body is caused by the casting process of the floor spring. If the blisters are caused to increase the hydraulic pressure inside the main body after the installation during the casting process, oil leakage may occur. The eccentricity of the earth axis can cause the door body to deviate from the center line of the door leaf after installation. Although some quality defects can be compensated by adjusting the body position, it is best to contact the manufacturer to replace it. The end of the service life of the floor spring is the shaft leakage and the weakening of the elastic force. If the axis connection between the sky shaft and the floor spring main shaft is not strictly perpendicular to the ground, the movement of the door leaf will bring great torsion to the floor spring and increase the main shaft. The wear between the bearing and the bearing will eventually cause the shaft to leak oil. The spring will inevitably weaken its elasticity after a long-term stretching exercise.

Floor spring installation and construction method
Detailed construction method of floor spring slotting:
The first step is to determine the position of the slot: first take out the main body of the floor spring and place it approximately at the pre-determined installation position. At this time, take a plumb line and place the vertical line from the center of the top shaft of the floor spring, and then move the floor. The position of the spring is such that the center of the plumb body is placed exactly at the center mark of the flat shaft of the floor spring. At the same time, pay attention to the level of the floor spring and the verticality of the front, back, left, and right directions, and then trace the outline of the floor spring body.
The second step, the implementation of grooving: use an angle grinder to cut a notch with a depth of about 3-5MM on the edge of the contour area of ​​the ground spring, and then use an electric hammer or hand chisel to excavate the contour area of ​​the ground spring. Floor materials, which can be used repeatedly with angle grinders, electric hammers, and chisels, chisels for details, electric hammers for larger materials, and angle grinders for sideline parts. At the same time, measure the depth of the floor spring groove, which is close to the thickness. At this time, you can put the floor spring body into the floor trough to see if it can be kept below the ground.
The third step is to stabilize the floor spring body: when the floor spring body can be completely put into the ground trough, the step of stabilizing the floor spring body can be carried out, but cement can also be used, but the cement setting time is longer. Take out the floor spring body, add an appropriate amount of quick-drying powder to the floor trough, add water and stir until the consistency is appropriate, then put it in the floor spring body, use a rubber hammer or a wooden block and then knock the floor spring with an iron hammer to make the floor spring You can restore the level of the surface to the surrounding ground, then use the plumb line to find the position of the ground spring axis, and fine-tune the ground spring body. After the above three steps, the grooving process of the floor spring body is finished perfectly, but there are a few points that must be paid attention to: (1) The size of the groove is appropriate, not too large or too small, too large will affect the appearance, if too small There are few stable materials, and the fixing is not firm. (2) The position of the axis of the floor spring must be accurate, and a plumb line or other tools for finding the vertical line must be used. (3) The consistency of cement or quick-drying powder used for stability is appropriate to ensure the strength of the stable floor spring. (4) After grooving and stabilizing the floor spring, be sure to wait until the cement or quick-drying powder has sufficient strength before installing the door body to avoid rework caused by the displacement of the floor spring.
