25ton eccentric press

Types of 25 ton eccentric presses

The eccentric press functions based on the principle of the driven disc creating an eccentric or off-centered circular motion which strikes workpieces to cut, mold, or shape them. Its basic components include the mainframe, worktable, die-cutting board, slider, ram, crankshaft, flywheel, clutch, brake, power transmission mechanism, and safety features.

According to the motion of the ram, eccentric presses can be classified into four main categories, each with distinct features and applications.

• 25 ton eccentric cylinder press :

  Its design feature includes a large circular worktable. The ram moves downward in a curved motion towards the center of the circular worktable before moving back in an upward curved motion. The direction of the movement also allows for easy access when loading and unloading workpieces. The 25 ton eccentric cylinder press is ideal for jobs that require frequent or fast die changes or operations that can be completed by a single operator from the top side of the machine.

• 25 ton eccentric horizontal press :

  Also known as the horizontal ram press, its ram moves horizontally from right to left. Its design feature includes an elongated worktable. The 25 ton eccentric horizontal press is suitable for jobs that require the processing of long-stripped work materials unless the material is cut into strips.

• 25 ton eccentric crank press:

  In this type of press machine, the crank rotates in a circular motion, moving the ram back and forth horizontally. The design includes a crank that is coupled with a connecting rod that is coupled to the ram. The machine can be used to cut, shape, or bend a variety of metals into complex forms and shapes. It is widely used in the automotive industry to manufacture body panels, complex automotive parts, and other components from sheet metal materials. It can also be used in the manufacturing of other industries for metalworking.

• Non-gear driven 25 ton eccentric clutch press :

  This machine does not include a gearbox in its transmission mechanism which reduces power loss and increases energy transformation efficiency.

Specifications & Maintenance

• Capacity

  The capacity of the 25-ton eccentric press is typically measured in terms of tonnage. Tonnage indicates the maximum amount of force the press can apply when shaping or forming materials. A 25-ton eccentric press would be suitable for light to medium-duty jobs, including forming, punching, trimming, and many other applications involving light gauge material.

• Speed

  This type of press may work at various speeds. However, the working speed of the machine may determine how fast the press operatively performs. The eccentric press's speed is further regulated by its control mechanism, stroke length, motor power, load capacity, and machining operations. An eccentric press with a higher RPM will complete tasks faster, ultimately increasing productivity.

• Worktable Size

  The size of the worktable is another specification that will vary for the different sizes of eccentric presses. This includes both the overall size and the usable area of the table. The worktable is where the material to be shaped or formed is placed. A smaller worktable would be more suited for smaller parts and vice versa.

• Floor Space Required

  The amount of floor space that a 25-ton eccentric press will take up will be determined by its overall dimensions, weight, and motor size. The area required is also proportional to the load capacity, worktable size, and other specifications. When setting up a machine in any given worksite, it is always a priority to determine how much floor space is needed to safely and easily position the machinery.

• Safety Features

  All presses must include certain safety features to ensure the machine's operator is safe and secure while working. Besides the mandatory emergency brakes and guardrails, safety interlocks, overload protection, and other additional features and specifications will differ from one eccentric press to the other depending upon the manufacturer.

Keeping a 25-ton eccentric press functional and efficient is important, but it is equally important to ensure the safety of the operator. The maintenance tips provided below will help keep the press at optimal conditions.

• Regularly clean and remove any debris, dust, or chips from the press's external or internal areas to prevent overheating.
• Each month, lubricate all the eccentric moving parts of the press. This may include bearing and shaft surfaces, gears, and guides.
• Every three months, inspect all the press components of the eccentric press. Repair or replace any damaged parts.
• Periodically check the eccentric press for oil leaks and clean any spills promptly.

Scenarios of 25ton eccentric presses

The 25ton eccentric press machine has diverse applications across various sectors and industries. Primarily, the machine is used for metal forming applications. This includes punching, coining, embossing, bending and forming of the metal work pieces. Mid-range or 25-ton eccentric presses can be easily used on softer metals like aluminum, brass, copper and alloy steel.

Industrial manufacturing plants use the 25-ton eccentric press to cut or punch holes on metal sheets in various sizes and shapes. The press machine has dies which are used to effectively make the holes as required.

Another great application of the eccentric presses is in the automotive industry. This involves assembly and manufacturing of different car parts. The car parts include gear wheels, body panels, internal brackets and clutch plates, among others. The metal sheets are either embossed or trimmed to form the shapes of the desired car parts.

The stamping method done by the presses are also used to create different types of watch pieces. An eccentric watchmaker can use the pressing machine to create watch cases, dials, movements and other related components.

The construction and HVAC industries also use the eccentric pressing machines to cut and punch metal sheets when forming duct components. Eccentric presses can easily form flanges, round pieces, and stack-up assemblies used in HVAC systems and Ducts.

The above applications only highlight some uses of the eccentric press machine. Manufacturers advise clients to ideally determine the uses of the machines. This will help them narrow down to the specific pressing machine with the right tonnage for their application needs.

How to choose a 25 ton eccentric press

• Needs assessment:

  Businesses should first assess their needs by considering their types of materials and parts, production volume, required press force, precision and tolerance, integration with existing equipment, floor space and budget constraints, and employee skill levels.

• Types:

  There are various types of eccentric presses based on their driving mechanism, trajectories, alignment, and applications. They may operate under different mechanisms, such as hydraulic, mechanical, air, electric, or manual, and have distinct ram movements and alignments. Buyers can decide which type of press suits their business needs.

• Safety Features:

  Business buyers should consider the safety features of the 25-ton eccentric press, such as emergency stop buttons, interlock guards, overload protection, two-hand operation controls, and stability features. An overload protection system stops the press if the cut-off switch is activated, preventing damage to the machine and component parts.

• Mold change:

  Consider the ease of die and mold changes. An efficient die change process helps shorten downtime and streamline production.

• Maintenance:

  Choose a 25-ton eccentric press with low maintenance. Consider its accessibility, maintenance requirements, and potential service costs. Select a press with features that reduce maintenance needs.

• Energy efficiency:

  Select an energy-efficient press model. Consider its energy usage and potential energy-saving features. An energy-efficient press helps minimize operational costs.
