Punching Machine

Power press is a type of machine tool used for punching, cutting, and shaping metal or other materials. It typically consists of a large frame that houses a moving punch and die, which work together to form a specific shape or hole in the material. Power presses can be manual or hydraulic, with hydraulic presses providing greater force and precision. They are commonly used in metal fabrication and other industrial applications. HARSLE is a leading brand within the punching machine market field due to its experience and quality standards, we produce mechanical press, Pneumatic press, CNC turret punch press and other power presses which are used in different metal-working fabrication areas.

Punching Machine FAQ

  • Q How to choose the right power press?

    1. Determine the type of power press you need: There are four main types of power presses - hydraulic, mechanical, pneumatic, and electric. Each type has its own advantages and disadvantages, so you need to determine which type is best suited for your needs.
    2. Determine the capacity you need: You will need to know the maximum weight of the material that you will be pressing, and the required force or tonnage to perform the job efficiently.
    3. Consider the speed and accuracy of the press: You need to determine the speed at which you need the press to work and the level of precision required for your work.
    4. Determine the size of the press: The size of the press will depend on the type of work you need to perform and the size of the materials you will be working with.
    5. Consider safety features: You need to ensure that the press you choose has safety features such as emergency stops, safety guards, and interlocks to prevent accidents.
    6. Look for additional features: You may also want to consider additional features such as automated feeding systems, programmable controls, and hydraulic or electric drive systems.
    7. Consider the cost: The cost of the press will depend on the type, size, and features you need.
    8. Get references and recommendations: Contact other manufacturers in your industry and ask for their recommendations and experiences with different power presses.
  • Q How to reduce punching machine noise?

    1. Install the sound insulation cover: Enclose the high-speed press transmission system and cover shell, which can significantly reduce the noise of the transmission parts. For motors with large power and high noise, a partial sound insulation cover or a closed sound insulation cover should also be provided. Outside the working area of the high-speed punch, installing a movable protective grille or sound insulation cover can make the noise reduction effect of the high-speed punch more significant.
    2. Installation of sound insulation room: The wall of the sound insulation room of the punch press adopts a special sound insulation material structure, which can effectively prevent the noise from scattering outward.
    3. Change the mold structure: the punching noise is proportional to the punching force. By changing the structure of the die, the punching force can be reduced and the action time of the punching force can be prolonged, that is, the oblique cutting edge is used. Step punch and heated blanking method to reduce stamping noise.
  • Q How to Calculate Punching Force?

    If you punch round holes or square holes,or some other forms of holes through a given thickness of metal. You must know the force. required to punch a hole in stelL. You can calculate the punching tonnage been required with the help of the following punching force calculation formula (blanking force formula):
  • Q What is the structure of the punching machine?

    There are various types of punching machines, but due to the different structural principles, the price and processing effects will also change accordingly. Of course, even for different types of presses, there is always commonality in the composition of the structure.

  • Q What is better, to punch holes in structural steel or drill?

    When you ask “What is better?” the answer almost always depends on which variables you are trying to optimize.
    To optimize the cost for a single hole, the kit for drilling is much cheaper than punching.
    To optimize for speed, punching (with the right tools) is orders of magnitude faster. (An Ironworker (machine) can punch a dozen half-inch/13mm holes in a minute.)
    To minimize deformation of the work-piece, drilling is better.
    To minimize heating of the work, e.g. to prevent work hardening, punching is better.
    If I have both a drill press and an Ironworker, I’m probably going to use the latter more than the former for structural steel. It’s so much faster. As a bonus it can also bend, shear, and notch metal too. They are great fun to use.
    This answer thanks to the guys at Lane Brother's Manufacturing in Virginia. They let me work there as a welder when the bottom fell out of the IT world. I'm indebted to them for taking that chance.
  • Q What is a mechanical punching machine?

    Mechanical punch, also known as mechanical punch, it uses the compressed air provided by the compressed air pump to enter the cylinder through the solenoid valve, and drives the piston to the main shaft to form a downward movement of the main shaft, thereby forming an impulse, so that the workpiece can be produced in the mold. deformation to achieve the purpose of processing.
    Working principle of mechanical punching machine
    The products or parts produced by punching machines or hydraulic machine tools for mechanical punching machines are called stamping parts. The basic elements are stamping power, male molds, female molds, and raw materials of the products (usually metal sheets or wires). The machine tool drives the male and female under the action of stamping power. The process of cutting, punching, and stretching the raw materials between the mold and the master mold is the working principle of the stamping machine.
    Also known as a mechanical punching machine, it uses the compressed air provided by the compressed air pump to enter the cylinder through the solenoid valve and drives the piston to the main shaft to form a downward movement of the main shaft, thereby forming an impulse, causing the workpiece to produce a specified deformation in the mold. To achieve the purpose of processing. In order to facilitate the use of customers, the electrical control part is also added to the equipment, which greatly improves the efficiency of work.
