Die-casting machine connecting rod function includes connecting piston to crankshaft, transmission of force, withstand complex loads,reducing weight and increasing efficiency,etc.
Die-casting machine connecting rod function
The main function of the connecting rod of the die casting machine is to convert the reciprocating motion of the piston into the rotary motion of the crankshaft. Connecting rod plays a vital role in the engine, it connects the piston and crankshaft. The piston’s linear motion into the crankshaft’s rotary motion, so as to drive the engine’s operation.
Its main functions include:
Connecting the piston to the crankshaft:
The connecting rod connects the piston to the crankshaft, converting the reciprocating linear motion of the piston into the rotational motion of the crankshaft.
Transmission of force:
It carries the task of transmitting the power generated by combustion from the piston to the crankshaft. And it must be able to withstand huge loads and transmit large amounts of power.
Subjected to complex loads:
Connecting rods are subjected to high pressure loads during operation due to pressure in the combustion chamber, inertial forces and friction, which generate stresses in the connecting rod.
Importance of design and materials:
The design and manufacture of connecting rods is a complex and time-consuming process involving material property analysis. As the reliability of the connecting rod is critical to the operation of the entire engine.
Optimized design of die-casting machine connecting rod:
Computer-aided design and analysis programs allow greater flexibility in the design of connecting rods and ensure shorter times for design changes.
The application of finite element methods allows for more reliable and realistic results. Thus optimizing the design of the connecting rod.
Reduced weight and increased efficiency:
The lightweighting of connecting rods improves engine efficiency, as reduced reciprocating weight reduces vibration and increases output power.
Exposure to high stresses of die-casting machine connecting rod:
Connecting rods experience significant tensile (during start/stop), compressive (during operation), shear and bending stresses due to centrifugal force during rotation.
Manufacturing technology:
Manufacturers typically forge connecting rods from high-strength malleable steel, which can be either carbon steel or steel alloys depending on the application.
Types and components of connecting rods:
Connecting rods can be divided into a small end, which attaches to the piston pin, and a large end, which attaches to the crankshaft pin.
Both ends of the connecting rod are fitted with bushings and the big end is divided into two parts and bolted to allow the connecting rod to be attached to the crankshaft.
Haichen die-casting machine connecting rod
Haichen is a die casting machine factory located in Ningbo, China, mainly supplying cold chamber die casting machine and hot chamber die casting machine. Besides machines, we also supply die casting auxiliary equipments and spear parts.
Haichen designs their connecting rods with an “H” or “I” section to ensure maximum stiffness and minimum weight, which is essential for maintaining stability under high stresses and at high speeds.
In addition, the connecting rod has the ability to withstand axial stresses, bending stresses, and inertia forces. It results from gas pressure in the cylinder, centrifugal force, and the reciprocating motion of the piston.
Together, these features and characteristics ensure that connecting rods will work reliably in a die-cast or diesel engine and are an integral part of the engine design.
