The punching pressure should be selected reasonably according to the product requirements and should not be blindly followed

Many customers do not know how much tonnage they need when purchasing punching machines. Either buying too big, or being deceived by the buyer, the tonnage of the punch sold is not enough, resulting in insufficient punch pressure during production and delaying the progress of product production. So how can I know how much pressure my product needs during processing, and what is the appropriate tonnage for choosing a punching machine?

Firstly, you need to clarify the type of board used in your product, the thickness of the board, and the diameter of the punched holes. Reasonably count the required punch pressure for the product to be processed using the punch pressure calculation method.

The calculation method for punching pressure is: perimeter×plate thickness× 50× 1.3÷1000=Tonnage.

For example:

1Comply with national standards304Stainless steel plate,thick1.5MM,Side length104MM,It's a square,ton=416*1.5*520*1.3=421824Approximately required45A punching machine with a ton of punching pressure!

2Cold rolled sheetQ235,thickness2.0, diameter108mm；T=108*3.14*2*40/1000*1.3=35Ton punch press

If you understand the technical parameters of the above punching machines, you can choose a punching machine manufacturer. When selecting a punch press, be sure to ask the buyer for the specific parameters of the punch press. Don't just look at the label on the punching machine or listen to what the buyer says. Because there are currently two types of punching machines sold in the market. One is the so-called non-standard, and the other is the national standard.

The so-called non-standard punch press refers to a smaller body than the national standard punch press, and its machine pressure generally cannot meet the standard. But the price is discounted, usually according to the national standard3/2Once you are going to choose such a punch press, it is recommended that you choose one level of pressure that is one level higher than your original budget for purchase.

There are other configurations on the punch press that you need to understand clearly. For example, the motor, shaft sleeve, and bearing shell on the punch press power device. These will all affect the future use of the punch press.

Of course, it is also directly related to the price of the punch press, as far as the motor is concerned; There are currently two types: copper core and aluminum core. If you blindly seek cheap prices when making a purchase, you will be deceived by the merchant. Speaking of which, no one would make a loss making deal in business. If you want to get cheap, you can only sell and grow punching machines.
