Various Mechanical Parts of Press Brake 2021-08-28
Press Brake is a machine that presses workpieces into different shapes according to requirements and bends thin plates. It is an important equipment for bending workpieces in the sheet metal industry. The bending machine is composed of a worktable part, a sliding block part, a back gauge part, an oil cylinder part and so on. 1. Cylinder The hydraulic cylinder is a hydraulic actuator that converts hydraulic energy into mechanical energy and performs linear reciprocating motion. The structure is relatively simple and the work is very reliable. The oil cylinder is basically composed of a cylinder barrel and a cylinder head, a piston, a piston rod, a sealing device, a buffer device and an exhaust device. It is fixed on the left and right sides of the bending machine and drives the slider to reciprocate up and down. 2. Slider The sliding block drives the upper die to perform reciprocating linear motion to realize the bending of the sheet metal to form a certain bending angle (or arc). The movement of the slider is divided into four processes: start to zero, fast drive,
The composition of the turning lathe 2021-08-19
Ordinary lathes generally refer to horizontal metal lathes, which are called industrial master machines. It is widely used and contains many basic mechanical elements of other machine tools. Only by knowing the structure and function of the lathe can we understand and use the lathe well. Usually a lathe is generally composed of a headstock, a bed, a saddle and a tailstock. The headstock is made of strong, non-deformable metal. It contains the main shaft and its supporting bearings and variable speed structure. The chuck that clamps the workpiece is mounted on the spindle. The main part of the lathe is the bed, which is made of cast iron, the guide rail is the ground surface of the bed, and the saddle and tailstock straddle the bed. The bed saddle supports the middle slide plate, small slide plate and tool holder, and moves along the guide rail in manual or automatic feeding mode. The square tool holder can install up to four knives, and each knife is locked with hexagonal screws. The slide box and the horizontal slide saddle form the bed saddle. The slide box is connected to the front of the bed saddle. It contains a mecha
The working principle of the shearing machine 2021-08-05
Hydraulic shearing machine is a kind of machine that uses a reasonable blade gap to apply shearing force to metal plates of various thicknesses by means of a moving upper blade and a fixed lower blade, so that the plates can be broken and separated according to the required size. After shearing, the shearing machine should be able to ensure the straightness and parallelism requirements of the sheared sheet, and minimize the distortion of the sheet to obtain high-quality workpieces. The upper blade of the shearing machine is fixed on the knife holder, and the lower blade is fixed on the workbench. Material balls are installed on the worktable to prevent the sheet from being scratched when sliding on it. The back gauge is used for positioning the plate, and the position is adjusted by the motor. The pressing cylinder is used to compress the sheet to prevent the sheet from moving during shearing. The guardrail is a safety device to prevent work-related accidents.
