Bending angle of steel wire repeatedly
In the repeated bending test of the steel wire, the common bending angle was 180°. In some daily operations related to steel wire performance testing, such as breaking the steel wire, a 90-degree bending angle would also be used. In addition, from the perspective of the safety bending requirements of the wire rope, the bending angle should be less than 45 degrees, but this is a limit on the bending angle of the wire rope from the perspective of safe use, which is different from the simple repeated bending test of the wire.

Metal wire bending testing machine
There was a factory in Ning Bo that directly supplied a manual wire rod bending testing machine at a price of 700.0 yuan. This kind of testing machine was mainly used for the repeated bending test of metal wires. It could test the performance of the metal wires in the repeated bending to withstand the plastic distortion and the defects displayed. The working principle was to pass a sample of a certain diameter through the guide sleeve and clamp it in two jaws of a specified size. After adjusting the height of the guide sleeve, press the button, and the sample will bend left and right 90°. After the sample breaks, it will automatically stop and record the number of bends. It is widely used in bar, steel, construction industry, steel wire, wire and cable production and testing institutions. <a href="/?from=ask_words" style="color:red" target="_blank">Read more exciting novels for free</a>
Which is better, steel wire cloth or steel wire ball?
Steel wire cloth and steel wire balls had some differences in terms of cleanliness. Steel wire balls were usually used to remove oil stains that were difficult to deal with. They had strong cleaning ability, but they required a lot of strength when used and might cause scratches on the surface of the object. Steel wire cloth combined the advantages of steel wire balls and dishwashing towels. It could clean ordinary oil stains, but it was not easy to drop silk, and it was easier to clean. Therefore, the choice of steel wire cloth or steel wire ball depended on the cleaning item and purpose. If it was a stainless steel pot, using steel balls might cause scratches and damage the protective layer, but steel wire cloth was more suitable. However, which one was better still needed to be decided according to personal needs and preferences.
How to cut the opposite angle of the open-wire pipe
There were several ways to cut the opposite corners of the open-wire pipe: 1. For surface mounted trunking, corner cut: - You can determine the turning point of the groove, draw a square with a marker, and draw a line connecting the opposite corners to get a 45-degree point, or directly measure it with a protractor to draw a line. - Then, he used a cutting machine or a cutter to cut along the line. The cut should be flat and smooth, and the grooves on both sides of the corner should be cut. - To make a flat 90-degree bend of 45 + 45 degrees on the opposite corner of the wire groove, multiply the height of the bridge by 0.4 to obtain the value W. After drawing the middle line at the required place, measure W on both sides to form a triangle, and then cut and bend the wire. - To make a 45+45 degree vertical 90 degree bend: multiply the width of the bridge by 0.4 to get the value W, draw the middle line at the required place, measure the W on both sides to form a triangle, and then cut the line to cut and bend. - To make two 45-degree duck neck bends: When making, take the opposite angles and measure the height of the two support beams. Multiply the height by 1.41 to get the oblique side (note that one side of the ruler is at the top of the 45-degree angle, and the other end of the ruler is at the corner point of the 45-degree triangle). <a href="/?from=ask_words" style="color:red" target="_blank">Read more exciting novels for free</a>
How much is a ton of 50 angle steel?

Requirements for the diameter of the lifeline steel wire rope
The requirements for the diameter of the lifeline wire rope in different scenarios were different. In some scenarios, the horizontal lifeline was mainly made of 8mm diameter 7*7 steel wire rope; in the standards for the installation and inspection of the lifeline, the diameter of the steel wire rope should not be less than 12mm, and the steel wire rope with a sheath should be used; In the commercial sale of the spot, the specifications of the plated steel wire rope without plastic coating were 1.2 mm- 10mm for the purpose of binding the lifeline. " The Island of Life " is also a wonderful novel. Everyone is welcome to read it!
The mountain is transported with steel wire rope and rollers
Steel wire rope was a common transportation method on the mountain. For example, there were mountain transportation wooden ropeway sports cars that used wire rope single-sided hanging wheels, and large U-shaped wheels that could be used to transport bamboo in the forest. The principle of transportation could be referred to the principle of polar rope transportation in mine transportation. It used a winding winches. One end of the wire rope was wound on the drum of the winches, and the other end was hung on the carrier of transportation (such as a mine car, which might be used to carry wood, bamboo, etc.). When the drum rotated, the carrier was pulled to run. The single-reel single-wire rope traction is single-hook transportation; two wire ropes are wound on two coax drums in different directions; the double-reel double-wire rope traction is double-hook transportation. When the drums rotate, the two groups of carriers at the ends of the two wire ropes run up and down on two tracks (if there are tracks) at the same time, and the transportation capacity is twice as large as that of a single-wire rope. At the same time, in order to ensure the transmission efficiency and service life, the diameter of the roller and the diameter of the wire rope should meet a certain multiple relationship. For large diameter wire ropes, if it is not suitable to use large wheels, a number of small wheels can be used to replace the role of large wheels. When the wire rope is wound into or out of the groove, the maximum deviation angle (i.e. the angle between the wire rope's center line and the plane vertical to the shaft of the wheel) should not be greater than 5°. However, the mountain transportation should choose the appropriate specifications of the sheaves and wire ropes according to the actual transportation weight. For example, the sheaves with a range of 200 - 2000 pounds had many different models that could correspond to the specifications of the wire ropes ranging from 6mm to 24mm.

The angle between the reflection angle and the incident angle increases
According to the law of reflection, the angle of reflection is equal to the angle of incidence. If the angle between the reflection angle and the incident angle increases, let the angle increase be the angle of the reflection angle, then it may be that the normal line is close to or far away from the incident ray, causing the incident angle to increase or decrease by the angle of the reflection angle. Because the reflection angle is equal to the incident angle, the reflection angle will also increase or decrease by the angle of the reflection angle, so that the angle between the reflection ray and the incident ray increases or decreases by the angle of the reflection angle. For example, in the problem of mirror rotation, if the normal line is far away from the incident light, the incident angle increases by angle (a), the reflection angle also increases by angle (a), and the angle between the reflected light and the incident light increases by angle (2a). <a href="/?from=ask_words" style="color:red" target="_blank">Read more exciting novels for free</a>
