How to design the master cylinder cylinder calculating the anode crusher

Crusher is a kind of squeezed abandoned the anode blocks or carbide crushing a crushing plant for reuse. While the role of the master cylinder is driven by a toothed plate crushed anode block, the cylinder tube is part of the hydraulic cylinder relating it with the end cap, Bottom, oil, mouth and other parts constituting the seal cavity for accommodating the pressure oil, it is the movement of the piston track. This article focuses on the design and calculation methods of the cylinder.

The design of the master cylinder cylinder, i.e. kiln correctly determine the dimensions of each part to ensure that the hydraulic cylinders have sufficient output power, velocity, and the effective stroke, and also need to have a certain strength to withstand the fluid pressure, the load force and unexpected impact. In addition, the inner surface of the cylinder tube having a suitable fitting accuracy, surface roughness and geometrical accuracy, in order to ensure the tightness of the hydraulic cylinder, smooth motion and durability.

① the output force of the hydraulic cylinder

F = abe, a, b are to be broken the length and width of the anode blocks, crushing e anodes is greater than or equal to 35.

2 hydraulic cylinder diameter calculation

Hydraulic cylinder diameter D can be calculated as follows:

, F is the hydraulic cylinder thrust (kN), P is the selected system working pressure (MPa).

③ cylinder wall thickness calculation and checking

Py is the pressure of steel drums experiments, σ] is the cylinder barrels material allowable stress.

④ of the cylinder tube material

Hydraulic cylinder cylinder commonly used material for seamless steel pipe 20,35,45 40 chromium. Normal circumstances, are made of 45 steel, quenched and tempered to 241 to 285. Cylinder blank forged steel, cast steel or cast iron pieces can be used. Cast steel can be 35 and other materials, cast iron or ductile iron can be several grades of 200 to 350.
