Simplify measurement by changing the size chain

Figure 1 is a schematic diagram of the large end machining of the sleeve shaft for diesel locomotives produced by our factory. The 30 (?) size in the figure is obtained after processing the A±α hole, but since the measurement standard and the processing standard do not coincide, and because the number of products is small, it is uneconomical to manufacture a special measuring tool, which brings a lot of processing and inspection to workers. trouble. This kind of problem is often encountered in multi-variety small batch production workshops. The ideal solution is

black concrete nails without anti-corrosion coating. The nails used in the construction, repair or manufacture of rough product are essential and the most simple. They are used to connect a variety of designs from rough wood structures, such as, formwork and scaffolding.

Black concrete nails are made from black carbon steel wires. We have several shank types for black concrete nails including smooth shank, ring shank, twisted shank, twilled shank. The head types of black concrete nails can be headless, round head. It offers good strength.

Production process

Modern apparatus for manufacturing nails completely automated and is a complex of several units assembled under one housing. Production of black nail the following stages : wire size specified from the bay by mangle the machine is fed into the nail unit is fixed and special grips cut to desired length . On the resulting workpiece using Upset slide is forming the cap and the tip of the stump . The nail is ready .

The black concrete nails application

popularity in the use of nails were black due to the low cost and ease of installation. Used for fixing the ordinary hammer. Construction black nails are widely used by carpenters, roofers and carpenters, as well as to create temporary connections and interior decorating for fastening wooden parts not exposed to moisture (internal structure, floors).

Today, this type of nail remains the undisputed leader in securing jobs and competitive price levels will only strengthen his position.

The disadvantage of black nails:

Due to the lack of galvanizing, these nails are easily prone to corrosion. Because of the instability of corrosion, their use in high humidity is undesirable. Also black construction nails do not apply in cases where the need is great appearance of the finished prod.
