The Punch press is a stamping pressure machine. In national production, because the stamping process is compared to traditional machinery processing, it has materials and energy, high efficiency, low technical requirements for operators, and products that can be achieved by various mold applications. So Its use is becoming more and more extensive. Stamping production is mainly for sheet metal. Through the molds, can make blanking, punching, forming, drawing, dressing, fine punching, shaping, riveting and extruding parts, etc., which are widely used in various fields. For example, we use the switch socket, cup, cup, plate, computer case, and even missile aircraft … There are many many accessories that can be produced with punching through molds.

One day in 2023, I received an inquiry from Customers from Ethiopia. He wanted to buy a punch press. Confirm the pressure of the punch press, we need to know the max thickness and size of stamping. According to the plate thickness provided by the customer, I recommend the customer to use 80T punch press. Then I asked the customer to need ordinary mechanical punch press or pneumatic punch press, but the customer did not know much about the difference between the two, So I explained the difference between the two with the customer. Ordinary mechanical punch press. It adopts horizontally placed crankshaft; Rigid rotated bond clutch; Manual shut height adjustment with scale display. It is a traditional brake method. The common ones are mechanical key -type brakes. The main stamping power is from the motor to drive the flywheel. The flywheel drives the crankshaft.

Pneumatic punch press. Welded body with steel plate and high intensity; Adopts combined pneumatic friction clutch and brake; Electric compelling grease lubrication system; The pneumatic punching machine is the inertia force of the pneumatic clutch to pass the flywheel to the crankshaft, connecting rod and slide block. The crankshaft connecting rod is rigid, so the slider movement is mandatory, the speed is the same, and the stroke frequency and motion curve of the slider are fixed. Using the high-pressure gas produced by the compressor, the compressed gas is transported to the solenoid valve through the pipeline, and the action of the solenoid valve is controlled by the foot switch to control the work and return of the cylinder, so as to achieve the purpose of punching.

The safety, precision and working speed of the pneumatic punching machine are higher than that of the mechanical punching machine, and of course the price is much more expensive than the mechanical punching machine, Also the pneumatic punching can Equipped with optional air cushion device, automatic feed shaft and photoelectric protector, which can used to work with various automatic equipment. Obviously, pneumatic punching is the best choice, but the customer said that he does not have many budgets. After we discuss, the customer decides to buy, the J23 series 80T mechanical punch. Soon we received the deposit from this Ethiopian customer. Through this customer, as a qualified sales, we must master the knowledge of the product and understand the differences between different series and different products, so as to recommend customers with cost -effective machines.
