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.

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.

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):

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.

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.

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.

How to use the punch press

A punch press is a stamping press. In national production, stamping process has the advantages of saving materials and energy, high efficiency, low technical requirements for operators and making products that can not be achieved by machining through various die applications. Therefore, it is more and more widely used.
1. Punch workers must learn and master the structure and performance of the equipment, they should be be familiar with the operating procedures and obtain the operation permit before they can operate independently.
2. The safety protection and control devices on the equipment shall be used correctly and shall not be removed arbitrarily.
3. Check whether the transmission, connection, lubrication and other parts of the machine tool and the protective safety device are normal. The die mounting screws must be firm and shall not be moved.
4. The machine tool shall run idle for 2-3 minutes before operation. Check the flexibility of foot brake and other control devices. It can be used only after it is confirmed to be normal. It is not allowed to run with defects.
5. The mold shall be tight and firm, the upper and lower molds shall be aligned to ensure the correct position, and the machine tool shall be moved by hand for trial punching (empty vehicle) to ensure that the mold works in good condition.
6. Pay attention to lubrication before driving, and remove all floating objects on the bed surface.
7. When the punch is taken out or running, the operator shall stand properly, keep a certain distance between his hands and head and the punch, and always pay attention to the action of the punch. It is strictly prohibited to chat with others.
8. When punching or making short and small workpieces, special tools shall be used, and it is not allowed to directly feed or take parts by hand.
9. When punching or obscene long parts, a safety support frame shall be set or other safety measures shall be taken to avoid digging injury.
10. During single flushing, hands and feet are not allowed to be placed on the hand and foot brake. They must be moved (stepped) once to prevent accidents.
11. When more than two people work together, the person responsible for moving (stepping on) the gate must pay attention to the action of the feeder. It is strictly prohibited to move (stepping on) the gate while taking parts.
12. Stop the machine at the end of the work, cut off the power supply, wipe the machine tool and tidy up the environment.

How much does a punching machine cost?

The prices for the punching machine vary from capacity, model, table size, type, throat, configurations and etc. HARSLE mainly offers mechanical press, pneumatic press and turret punch.
Mechanical Press
The price for mechanical press depends on the throat depth, capacity, stroke adjustment, clutch and etc. The minimum capacity is 6.3T, the biggest capacity for mechanical press is normally 200T. stroke adjustment and air clutch are the optional configurations for this type of the machine. The price starts from $1,000 and we can also customize the machine according to customers’ request.
Pneumatic Press
For this type of punching machine, it will be much more expensive than mechanical press machine, but it features high precision, more safe, high automation and working efficiency, This type of machine can work together with the servo feeder and decoiler for mass production and the pneumatic press mostly is equipped with the CNC controller for easy programming and it is widely accepted by automobile industry and hardware industry. The minimum capacity is 25T and the price starts from $10,000. If you need bigger worktable, you choose our double-point press, it can work with progressive die and improve the working efficiency largely.
CNC Turret Press
This type of machine is widely used in Aluminum sheet fabrication and electric cabinet fabrication. Its working station is the main part of the machine and it can work with maximum 32 different set of molds together which can improve the punching working efficiency largely. Its price is also much higher than pneumatic press
