The breaker bolt has long and short bolts. The long and short bolts are divided into side plate bolts and through bolts. The side plate bolts are also called splint bolts, and the through bolts are also called through-core (through-body) screws. The splint bolts and the whole body bolts are made of 40cr, 42crmo special steel, which is more flexible and anti-loosening. Small bolts are very important to the life of the hammer body and the steel drill. 1. Through bolts (through bolts) are generally produced with grade 12.9 alloy structural steel. Through bolts are important co

What are the functions of linear guide sliders?
Linear guides are collectively referred to, including sliders and rails. Linear guides are also called linear slides, linear slides, linear guides, guide rails, and slide rails, which actually refer to the same thing. Generally speaking, linear guides refer to square tracks, guides with two or four tracks, and of course some people call linear bearings and optical shafts linear guides, or circular guides. Now let me tell you what the rail slider does? 1. High working accuracy: The movement of the linear guide is realized by rolling, not only the friction coefficient is reduced to 1/50
Benefits of Sumo Deadlifts More flexible than regular power bars: Deadlifting on regular bars means pulling from "dead", in other words, from zero to 100% of your weight at a time. However, with a more flexible bar, the center of the bar will rise 3 or 4 inches before the weight starts to lift, and as they do, the inner plate will lift first, moving to the outer edge. The result of this is a smoother, more progressive acceleration of the weight, allowing you to lift more of the actual weight. Most lifters who use deadlifts will tell you that they can lift 40 or 50 pounds more with a dea

camshafts,tractor camshafts,camshaft tractor parts,
A camshaft is a component in a piston engine. Its function is to control the opening and closing of the valve. Although the speed of the camshaft in a four-stroke engine is half the speed of the crankshaft (in a two-stroke engine, the speed of the camshaft is the same as that of the crankshaft), but usually its speed is still very high, and it needs to bear a lot of torque, so the design of The camshaft has high requirements in terms of strength and support, and its material is generally high-quality alloy steel or alloy steel. Since the law of valve motion is related to the power and ru
How are the auto parts produced?
The processing technology of auto parts includes casting, forging, stamping, welding, powder metallurgy, plastic molding, etc. 1. Casting is the most commonly used blank production method in the automobile manufacturing process. Auto parts and components that account for about 10% of the total weight of the car are obtained by casting. For various auto parts with complex shapes that are difficult to form by other methods, as well as various parts that require wear resistance, pressure bearing

Electrical steel demand will increase
Electrical steel is a soft magnetic alloy of ferrosilicon with very low carbon content, and is an indispensable material in the power, electronics and military industries. According to statistics, the total output of electrical steel in the world in 2000 was 6.714 million tons, and by 2005 it had exceeded 8 million tons. At present, the consumption in the domestic market has far exceeded 3 million tons. Among them, non-oriented silicon steel is the iron core material of the rotors of motors and generators working in a rotating magnetic field, and require
Automotive half shaft steel material
The grades of half shaft materials are 5140, 4140, 40MnB, 40CrMnMo, 4135o, 35CrMnSi, 5140V and 1045 steel and other materials that can meet the requirements of this standard. The selection of materials for shaft parts is mainly determined by the strength, stiffness, wear resistance and manufacturing process of the shaft with the factors to be economical and reasonable. Commonly used shaft parts materials are 1035, 1045, 1050 high-quality carbon steel. 1045 steel i
Types of Knurling for Weightlifting Barbell Bars
In the gym, the barbell is the most common training equipment, and the more common it is, the easier it is for people to ignore the details. For example, each bar has a fine pattern called "knurling" engraved on it, which increases the friction of the trainer's grip on the bar, giving them a firmer grip. However, the knurling on the barbell may cause secondary injury if you are not careful! Have you ever noticed that the knurling on this barbell is the same or different? According to the purpose of training, barbells can be divided into weightlifting, powerlifting and bodybuilding. (Discussed
