Electrical punch press machinery

Types of Electrical Punch Press Machineries

An electrical punch press machinery is a tool used to strike metal with a great force. It is part of the metal forming machine that changes sheets or metal plates into different shapes. The primary feature of this machine is the electric motor used to operate it. Everything else remains the same as in any punching press machine. The electric motor replaces other power sources, such as hydraulic motors or gears and clutches driven by electrical belts. The electric motor provides simple maintenance and consistent force and control over the punched parts.

Electrical punch press machines are not limited to only one kind. There are many varieties of punch presses that use electricity in their working parts. Some standard types are listed below:

• Electron beam punch press (EBM): An electron beam punch press (EBM) is a beam-based manufacturing technique that uses a beam of electrons to perform various machining tasks. It uses a sophisticated machine known as an electron beam machine that can do various jobs. This can include piercing the metal, cutting, or even welding parts together. An electron beam punch press will cut with excellent accuracy and precision to make complex shapes in metal sheets or plates with ease. The punches will change the direction of the electron beam to make the desired patterns. The beam will then heat the metal until it becomes soft. It will then change its shape according to the requirements. No additional parts are needed to change to make different designs.
• Hydraulic punch press: A hydraulic punch press machine works on the same principles as a hydraulic machine. A hydraulic machine uses hydraulics or fluid power to move the parts and make them work. In a hydraulic punch press, the fluid pressure is used to move a ram or piston to punch holes in metal sheets or plates. It changes shapes according to the desired specifications. The main feature of this machine is that it can control the pressure and speed with a lot of force. This makes it very usable in heavy industries where thick metal sheets are used.
• Electromagnetic punch press: An electromagnetic punch press machine (EMP) uses electromagnets to press buttons in metal sheets and plates. It is also known as a die-less punching machine. An EMP machine comes with many benefits, such as easy maintenance and low energy consumption. This machine stands out from the rest because it can perform a variety of jobs besides punching. These include blanking, piercing, and trimming. Aluminium, copper, brass, and carbon steel sheets can easily be handled by this machine. No, work dies are used, making it easier to change the material.
• Servo gear-driven punch press: A gear-driven punch press machine works on similar principles of using gears to drive the motor to move and punch metal sheets and plates into different shapes. The gear then changes the motor's speed and torque, which is the force needed to do the work. It is very useful to handle thick metal plates.

Specifications and maintenance of electrical punch press machinery

Specifications

The specifications of an electric punching press machine may vary depending on the model and manufacturer.

• Power: This generally ranges from 3kw to 15kw, depending on the capacity and size of the machine. Larger machines will naturally have higher motor power to perform greater capacity.
• Feeding system: The automatic feeding length generally ranges from 1000mm to 5000mm, while the automatic feeding width is between 200mm and 1000mm. The lengths and widths of the feeding systems vary according to the size and models of the machines.
• Cutting speed: For rotary cutting, the speed is about 250-350RPM (revolutions per minute), which is equivalent to 85-100 cuts per minute. The cutting speed for sabre cutting is about 150-200RPM (revolutions per minute), which is further equivalent to 60-70 cuts per minute.
• Cutting capacity: An electric punching machine press can cut various kinds of metals depending on the blades or saws manufacturers use. For rotary cutting, it can cut aluminum alloy strips, copper alloy strips, iron strips, stainless steel strips, carbon steel round pipes, stainless steel round pipes, galvanized round pipes, PVC pipes and others.
• Die: An electrical punch machine comes with different types of dies to suit other applications. According to different requirements, some may be designed to create holes while others are intended to shape particular features.

Maintenance Tips

• Lubrication: Regular maintenance usually involves constant lubrication to keep the moving parts smoothly operating and reduce the risk of wear and tear. Operators should focus on the machine's oil pump, guide rails, chains, gears, bearings, and other lubrication points. Only use high-quality lubricants that manufacturers recommend lifting, pouring, or injecting them onto the designated areas, ensuring an adequate amount.
• Cleaning: Keeping the electric punching machine press clean is very important for health and prolonging life. Manufacturers usually advise operators to use compressed air or brushes to remove dust, debris, and metal shavings. Carefully clean crevices and hard-to-reach areas. The operators can also use an appropriate cleaning solution or solvent to clean sticky residue. After cleaning, ensure that all parts are completely dry before using the machine again.
• Die maintenance:
• Electrical maintenance: Regular inspections are essential electrical punch machines for signs of wear and tear, such as loose, damaged, or worn belts. This includes checking for proper tension to ensure effective power transmission. Other parts that require a constant check include the cooling system, hydraulic system, and sensors.
