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>
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.

wire rod
Coiling was also known as wire rod, wire rod, etc. It was a raw material produced by major steel factories. Most of them were supplied by coiling them up on a coiling machine. In the standard parts industry, it can be used as a raw material for the production of bolts (the commonly used plate grades in bolt factories are Q195, Q235, 35K, 10B21, 10B33, 40Cr35CrMo, SCM435, etc.). It can also be used as a raw material for reinforcing and welding structural parts of reinforced concrete or for re-processing (such as drawing wire, drawing, etc.). According to the steel distribution catalog, the wire rod includes ordinary low-carbon steel hot-rolled wire rod, electric welding wire rod, explosive wire rod, quenched and tempered thread wire rod, and high-quality wire rod. The disc cleaning machine could be used to clean the discs. This cleaning method was non-polluting and could improve the internal quality of the steel bars, eliminate internal stress, and improve fatigue resistance. In terms of price, the prices of different specifications, brands, and manufacturers were different. For example, on October 17,2024, the price of the northeast special steel plate of <anno data-annotation-id ="00000000 - 4110 - 4410-a100 - 999999999999"> 5.5 -</anno></anno></anno> was 9090 yuan/ton in Chengdu market. In terms of equipment, there was a five-wheel circular tube coiling machine that could coil round (circular tubes and other shapes). The test machine operation was to put one end of the tube between the upper and lower mold wheels with a good distance. During the operation of the equipment, the tube was gradually rolled into shape. In addition, China Wuye Group Co., Ltd. obtained a patent called "A kind of round steel bar bracket". Its structure included two U-shaped supports, curved rods, two connecting rods, etc., which could realize the orderly stacking of round steel bars, avoid corrosion during storage, and play the role of fixing round steel bars.

conjoined inward bending
The conjoined inner bend was a pipe fitting used to connect a fixed distance water mixing valve. It could be connected to the hot and cold faucet in the home decoration, the hot and cold faucet in the sink, the entrance and exit of the water heater, and the mixing valve in the sink for washing vegetables. The appearance of the conjoined inner bend made it easier for the plumber to operate, solving the difficulties caused by the poor control of the distance between the two outlets and the unequal control of the level. It brought convenience to the plumbers, reduced unnecessary trouble, and reduced the economic losses of the owners.
90 Techniques for Bending Tubes
In the process of bending the wire tube, there were a few techniques that could help achieve a 90-degree turn. First of all, the gestures had to be standard and could not be bent with the legs. Secondly, when making a bend, it should be slightly larger, such as a 90-degree bend. The angle of the finished product should be slightly lower than 90 degrees, and then adjusted to 90 degrees when it was installed. If the finished product was more than 90 degrees, a spring was needed to adjust the tube inward, otherwise the tube would flatten. In addition, the line pipe has a certain degree of flexibility, but it cannot be bent directly, otherwise it will damage the PVP pipe. The correct method was to insert a spring into the tube first. This was simple, fast, and beautiful. For standard pipes, a pipe bender could be used to bend them. For non-standard pipes, if the thickness of the pipe wall is sufficient, it can be filled with sand and locally heated, and then bent with a pipe bender. If the pipe wall is thin, an elbow is needed. In short, when bending the tube, following the standard gestures, bending slightly wider, using the spring to insert the tube and other techniques can help achieve a 90-degree bend.
Is 'The Wire' a science fiction?
Definitely not. 'The Wire' is more about the gritty and complex social issues in a city rather than having any elements of science fiction. It delves deep into the workings of the police, drug trade, and politics.
