Brief Profile of Double Crank C Frame Press Machine

A Double Crank C Frame Press Machine is a type of mechanical power press machine used for shaping, cutting, and punching sheets of various materials, including metal, plastic, and paper. As the name suggests, the machine has two crankshafts located at either end of the frame, which drives the slider up and down.

The machine consists of a frame made of high-quality steel plates, die tooling, and a double crankshaft mechanism, which is operated by a motor. The motor drives the flywheel, which then drives two crankshafts, connecting rod mechanism, clutch, and transmission gear to move the slider up and down.

The C-shaped frame design of the machine provides maximum accessibility to the workpiece and allows for easy handling of the materials during production or maintenance. The machine is designed to withstand heavy loads and rapid cycling, with an adjustable stroke of the slider in 8 gears to meet the processing requirements of various dies.

Double crank C-frame press machines are commonly used in medium to large-scale manufacturing operations for shaping, cutting, and punching medium to large-sized sheets of materials. The machines are versatile and can be used for a range of applications, including bending, stamping, and forming.

Overall, the double crank C-frame press machine is an efficient, reliable, and cost-effective solution for metalworking, plastic, and paper industries, with high precision and durability. This machine is suitable for high yield and stability continuous stamping operations. It is also ideal for operations that require a high volume of production and greater precision than a single crank C-frame press machine can provide.

Features of Double Crank C Frame Press Machine

● Steel welded body, tempering treatment, high rigidity, accuracy and stability, low integrated clearance, small changing in mold height.

● Small deviation of dynamic center, the mold life in large scale, small transfiguration for press.

● The crankshaft undergoes grinding treatment after high frequency quenching.

● The transmission gear is spur gear, the tooth surface is quenched and heat treated by medium frequency, with high transmission accuracy, high meshing accuracy, smooth transmission, large bearing capacity, strong gear strength, low noise and other advantages. Ensure reliable lubrication.

● Synchronous transmission system is a set of gear system connected by the main gear, to ensure the synchronous transmission machine drive shaft operation and slider movement synchronization, so as to ensure the synchronization of control signal and slider movement.

● The slide block adopts super-long eight-side guide rail with high guiding accuracy and good wear resistance. The gap of guide rail can be adjusted by push-pull bolt. The slide block guide board is made of copper-nickel alloy.

● The slider is equipped with hydraulic overload protection device, gas-liquid type, overload response will be generated when the rated tonnage is about 5%, and the slider will automatically stop when the alarm is given. After overload, the pressure recovery time is less than 3 minutes, and the manual unloading knob is set.

● The structure is strong enough to support the weight of the machine and the vibration generated by the punch press.

● High precision processing, high efficiency operation, machine to ensure products of high quality.

● Facilitate the operation of implementation, fixed locking type six-surface guide way, cutting low-noise, safe and reliable operating state.
