What is a Hand Press?

The hand press is mainly used for the disassembly of gears and shaft sleeves and the correction of deformed parts. It is a kind of mechanical equipment widely used in product assembly and maintenance. The press is a versatile press with a compact structure. With a wide range of uses and high production efficiency, the press can be widely used in cutting, punching, blanking, bending, riveting and forming processes. It is processed into parts by applying strong pressure on the metal blank to plastically deform and break the metal.

When choosing a press, try to use a multi-purpose device. As the diameter of the workpiece to be corrected is different, different presses are used. When calibrating smaller and longer workpieces, manual presses are often used. The manual press has a simple structure and is easy to operate. It is divided into a rack type and a screw type. The figure shows the structure of a manual press. (A) in the figure is a rack-type manual press. Its working pressure is generally 1-5 tons, and it is often used to correct workpieces with a diameter of 5-10 mm. (B) in the figure is a screw-type manual press. Its working pressure is generally 2-25 tons, which is often used to correct workpieces with a diameter of 10-30 mm. Manual presses have lower production efficiency and lower pressure. ^[1]

The hand press consists of a frame, a worktable, a pad and a hydraulic head. The worktable is lifted by the lifting device on the beam and moves along the frame column. There is a support on the column to fix the worktable. The hydraulic head is clamped on the bottom surface of the frame beam. The oil cylinder and two different functions of the plunger oil pump constitute a more complete hydraulic system. The device is centralized, the volume is small, no power is needed, and the pressure processing task is completed manually. ^[2]

Hand pressing prototype, suitable for various industries and scientific research institutions for tensile pressure load, insertion force, material sample preparation. The rack-and-pinion rack adopts gear pair transmission and manual pressure operation. The up and down height of the indenter can be adjusted. When calibrating the workpiece, pull the handle by hand to lower the rack and press the workpiece. Structure, simple and stable operation, fast and efficient, suitable for batch testing. For screw-type calibration of the workpiece, first place the workpiece on the stand of the machine base, and then turn the hand wheel ring (or handle) to lower the screw and compress the workpiece. ^[1]

The hand press is a small and compact stamping equipment. It has the characteristics of exquisite structure, superior performance, convenient operation, stable accuracy, safety and reliability, etc. The closed height and stroke length are adjustable, and the structure is compact and easy to operate.

Hand presses, generally with relatively low working pressure, 1 ton, 2 ton, 12 ton, etc., and 100 ton. Punching, cutting, chamfering, warping, stamping, printing and other light load precision requirements. The hand press is suitable for watches, meters, electronics, jewelry, zippers, hardware, clothing, shoes and hats, etc. It can punch, bend, rivet and press-fit the workpiece. It can process metal, non-metal sheet, strip, coil material in the process of cutting, punching, blanking, bending, shallow stretching, crimping, riveting and forming. ^[2]
