Tab washers with long and short tabs at right angles-Structural design

Cold stamping is a processing method that uses a stamping die to exert pressure on a sheet in a press at room temperature to separate or deform it to obtain parts of specific shapes, sizes, and properties. Cold stamping is an advanced metal processing method based on the plastic deformation of the metal. Due to the different shapes, sizes, precision requirements, batch sizes, and raw material properties of cold stamping parts, many other stamping methods exist. Still, they can be divided into two categories: the separation process and the deformation process. The separation process separates the stamped parts or blanks along a specific contour from each other; the deformation process in the material does not produce damage under the plastic deformation of blanks, the formation of the required shape and size of the parts. Stamping can be divided into five basic processes: blanking, bending, deep drawing, forming, and three-dimensional pressing. The cold stamping process has the following characteristics compared with other processing methods:

1. Cold stamping can be used to obtain workpieces with complex shapes that demand processing and other processing methods. The molds guarantee the dimensional accuracy of cold-stamped parts, so the dimensions are stable and interchangeability is good.

2. High material utilization rate, light weight of workpiece, good rigidity, high strength, and less energy consumption in stamping. Therefore, the cost of the workpiece is low.

3. Simple operation, low labor intensity, easy-to-realize mechanization and automation, and high productivity.

4. The mold structure used in the stamping process is generally more complex, the production cycle is longer, and the cost is higher. Therefore, in a single piece,

Certain restrictions apply to small batch production using the stamping process, which is mainly used for batch and mass production.

How do you effectively prevent the bolt from singing when there is a phenolate in the bolt processing process? The phenomenon requires the application of tab washers with long and short tabs at right angles. As the name suggests, a double lug stop washer is used with the nut to prevent the nut from loosening a washer on the two prominent "small ears." It and the outer tongue stop washer, single ear stop washer, etc., are the same as the general nut locking occasions, but according to the structure of the connected parts, the different needs to use other forms. Then, how do tab washers with long and short tabs at right angles in the end play the role of stop?

The use of metric tab lock washers  with long and short tabs at right angles and application industry solutions

1. Put the bolt through the double lug, stop the washer, and screw the thread (when not tightened).

2. The double lug stop washer "long tongue" close to the edge of the compression parts folded down.

3. When the hexagonal nut (the hexagonal bolt is also the same) is tightened, will tab washers with long and short tabs at right angles "round ears" stand up, respectively, to the nut and are connected to the side of the folded tightly, attached to the side of the nut or bolt on the plane.

Using Tab washers with long and short tabs at right angles, the nut (bolt) can not be rotated, so that can quickly achieve the purpose of anti-loosening. Tab washers with long and short tabs at right angles can prevent the parts from loosening or sliding. In practice, it is often used in the assembly process of various mechanical equipment,  especially when there is a need to withstand a significant vibration or impact. Double lug stop washers are used in automobiles, motorcycles, aerospace, electrical equipment, communication equipment, catering equipment, medical equipment, solar energy, photovoltaic industry, and other fields.

Principle of operation of double lug stop washers

From the Principle, using tab washers with long and short tabs at right angles to anti-loosening belongs to mechanical anti-loosening, which uses a variety of stop parts to prevent the relative movement of the tightening of the threaded parts. The advantages of this method are apparent: reliable anti-loosening, complex structure, high space requirements, assembly needs to be done, applicable to small quantities of not easy to check place, and the anti-loosening requirements are rigorous threaded connections, such as significant impact, vibration, high-speed occasions. The working Principle of the tab washers with long and short tabs at right angles gives it the following advantages:

1. Simple and reliable: the structure of the tab washers with long and short tabs at right angles is relatively simple, has low manufacturing costs, and is easy to use. At the same time, its working Principle is also relatively reliable and can effectively prevent the loosening or sliding of parts.

2. Space saving: The tab washers' compact structure, with long and short tabs at right angles, occupies less space, allowing for the fixing of the parts in limited space and improving the compactness of the overall assembly.

3. Reusable: Tab washers with long and short tabs at right angles can be used several times during the assembly process without losing their function due to deformation under stress. This makes the double lug stop washer economical and environmentally friendly.

As a standard mechanical part, tab washers with long and short tabs at right angles are essential in various assembly processes. Their unique working Principle prevents the loosening or sliding of parts through friction and elastic deformation, ensuring the stability and reliability of the assembly. In practical application, we should choose the appropriate double lug stop washer according to the specific assembly requirements and use it correctly to ensure the quality and safety of the assembly.
