How to do 300X100 bridge tee

1. Straight section: indicate the full length, number of layers of the bridge, elevation, model and specification. Bend point and branch point: indicate the model and specification of the turning adapter used. Lifting section: indicate the elevation change, which can also be represented by a local sample or section drawing.

2. Determine the direction: according to the building layout plan, combined with the setting of air conditioning pipelines and electrical pipelines, convenient maintenance, and the density of cable routing to determine the best route of the cable tray.

3. Load calculation: calculate the weight of the cable per unit length on the longitudinal section of the main trunk of the cable tray.

4. Determine the width of the tray: determine the model and specification of the cable tray, the length of the supporting arm, the length and spacing of the pillar, the width and the number of layers of the tray according to the number of cables, the diameter of the cable and the spacing of the cable.

5. Determine the installation method: determine the fixing method of the bridge according to the setting conditions of the place, choose the suspension type, the vertical type, the side wall type or the hybrid type, the connectors and fasteners are generally matched, in addition, the corresponding cover plate is selected according to the bridge structure.

6. Draw the flat and cross-sectional drawings of the cable tray, and the local parts should also draw the space map and list the material table.

Determine the size of the bridge at hand, 200*100 bridge, and make a 30-degree uphill elbow. With the help of a mobile phone computer, the blanking size is calculated. Through the previous step, the blanking size is calculated.

The next step is cutting, and the three lines are the blanking size, which can be combined to make a bridge tee.

Bridge tee draws the route of bridge on parallel diagram, should indicate the coordinates or positioning size, elevation of bridge starting point, end point, turning point, branch point and lifting point, if you can draw bridge laying axis side diagram, then material statistics will be more accurate.

Use a ruler to take the center line, 45 degrees on one side, and then remove the 45 degrees on one side.

This picture is a diagram of 200mm wide bridge horizontal 90 degree elbow cutting and production: according to this figure, other specifications of elbows can be made.

Tees are pipe fittings and pipe connectors. It is also called pipe fitting tee or tee pipe fitting, tee joint, which is used in the main pipeline to branch pipe. Stainless steel equal-diameter tee.

Tees are divided into equal diameter and different diameters, and the end of the pipe of equal diameter tee is the same size; The size of the main pipe of the reducer tee is the same, while the size of the branch pipe is smaller than that of the main pipe. Tee is a type of pipe fitting used at the branch of the pipeline. For the use of seamless pipe to manufacture tees, there are two kinds of processes usually used at present: hydraulic expansion and hot press forming.

a.Hydraulic expansion The hydraulic expansion of tee is a forming process that expands out of the branch pipe by axial compensation of metal materials. The process is to adopt a special hydraulic press, inject liquid into the tube blank equal to the diameter of the tee, squeeze the tube blank through the synchronous centering movement of the two horizontal side cylinders of the hydraulic press, the volume of the tube blank becomes smaller after being extruded, the liquid in the tube blank increases with the volume of the tube blank becomes smaller, when the pressure required for the expansion of the tee branch pipe is reached, the metal material flows along the inner cavity of the mold and expands out of the branch pipe under the dual action of the liquid pressure in the side cylinder and the tube blank.

The hydraulic expansion process of tee can be formed at one time, and the production efficiency is high; The wall thickness of the tee and shoulder has been increased. Due to the large tonnage of equipment required for the hydraulic expansion process of seamless tee, it is mainly used in the manufacture of standard wall thickness tee less than DN400 in China. Its suitable forming materials are low carbon steel, low alloy steel and stainless steel with relatively low cold work hardening tendency, including some non-ferrous metal materials, such as copper, aluminum, titanium, etc.

b.Hot press forming Tee hot press forming is to flatten the tube blank larger than the diameter of the tee to the size of the tee diameter, and make a hole in the part of the stretched branch pipe; The tube blank is heated, put into the forming die, and the punch of the stretched branch pipe is loaded into the tube blank; Under the action of pressure, the tube blank is radially compressed, and in the process of radial compression, the metal flows in the direction of the branch pipe and forms a branch pipe under the stretching of the die. The whole process is formed by radial compression of the tube blank and the stretching process of the branch parts.

Different from the hydraulic bulging tee, the metal of the hot-pressed tee branch is compensated by the radial movement of the tube blank, so it is also called the radial compensation process.

Is it a horizontal tee? Vertical tee? Normal, or non-standard tee?

Do it flat or vertical?

1. Take the 90-degree bridge elbow as an example, and so on at 45 degrees: 2. The length of the bottom edge of the bent bridge (bottom hypotenuse) can be the same length as the width of the bridge, but the range is controlled at 100 400mm; 3. Select two points of this length, draw two vertical lines relative to the bottom edge on the side of the bridge, and select the bending direction of the bridge as the cutting opening side; 4, select the opening side as the bottom edge, draw two vertical lines respectively as the middle line of the two isosceles triangles, the determination formula of the length of the bottom edge of the isosceles triangle is l 2 (bridge height, the simple algorithm is to take the 100 high bridge as an example, the length of the bottom edge of the isosceles triangle is, that is, 100:, and so on The length of the bottom edge of the isosceles triangle when the high bridge is bent in turn, this proportion is also suitable for the restructuring of the horizontal 45 ° elbow; 5. After cutting off the isosceles triangle with a tool, the 90° bridge elbow formed by two 45° bends can be obtained by bending the bridge.

6. As for the modified elbow that limits the length of the bridge, as long as the simple mathematical knowledge learned in junior high school is used to calculate, any length distance can be controlled. Depend on.

Summary. How to do 300 bridge to 200 bridge**: pro 300 bridge to 200 bridge** is as shown in the figure with a Y-shaped joint on the top and bottom small, you can also use the size of 300 to cut yourself, and then bend it to 90 degrees with a bending machine.

However, it is not safe to make it yourself, so it is better to buy the finished product directly.

Hurry up. How to do 300 bridge to 200 bridge**: pro 300 bridge to 200 bridge The old solution is as shown in the figure Use the Y-shaped joint to rise and fall into the hall, or you can cut it yourself with the size of 300, and then bend it into a jujube ruler 90 degrees with a bending machine.

However, it is not safe to make it yourself, so it is better to buy the finished product directly.

Dear, hello, I am glad to answer for you the 300x150 bridge up and down 45 do this,) 45 degree elbow: hypotenuse = height bottom edge = height upper and lower pants early chain turn intox cut width = the height of the side plate of the trunking left and right flip the incision width = the width of the bottom plate of the trunking For example: 200 (bottom) x 100 (side) of the trunking, after the meter to turn up 20 cm (height), we can calculate it like this:

Hypotenuse 28 = bottom edge 20 = 20 up and down the incision width The result is to remove two zeros or use attention: the height is the height we want to turn, the bottom edge is the length of the elbow after the elbow is done, if we want to do our good Husun elbow just put on the bracket from our meter, we will use this bottom edge, m - 20 cm (bottom edge) = 130 cm, then we can start to do the elbow at 130 places, and the elbow can be placed on the bracket of the meter after doing a good job, it is recommended to leave a little, Because the stent may not be straight, the stent cannot be adjusted to this side if it is directly stuck.
