● what is a punch press machine
punch press machine The full name is punch press, which is a type of mechanical equipment that uses pressure to cause plastic deformation or separation of metal sheets, thereby obtaining parts of the required shape and size. Its core working method is: a motor drives a slider to reciprocate up and down, an upper die is mounted on the slider, and a lower die is fixed on the worktable. When the slider presses down, the upper and lower dies close together and exert enormous pressure on the sheet material clamped in between, completing two types of processing: first, punching and separation (punching, blanking), and second, plastic forming (bending, drawing).
Main features Extremely high efficiency: one stroke can complete one or more processes, with dozens to hundreds of strokes per minute, suitable for large-batch production. Die-dependent: what shapes can be processed depends on the die. The die determines the precision and shape of the product, so die costs are relatively high. Widely used: the automotive, home appliance, electronics, hardware, and other industries use it extensively to manufacture housings, brackets, connectors, and so on.
Common classifications mechanical punch press machine: driven by a crank connecting rod, with a fixed speed, suitable for large-batch blanking and bending. hydraulic punch press machine: driven by hydraulics, with high and adjustable pressure, suitable for drawing, extrusion, and other processes requiring slow speed and high force. pneumatic punch press machine: driven by compressed air, mostly used in small-tonnage, high-frequency applications. Open-frame punch press: the body is C-shaped, open on three sides, convenient to operate, suitable for small and medium-sized parts. Closed-frame punch press: the frame is enclosed, with good rigidity, suitable for large and precision parts. High-speed punch press: extremely high stamping frequency and high precision, compatible with continuous dies for coil stock, aimed at small precision thin hardware parts. cnc turret punch press machine (CNC turret punch press): built in with multiple die stations, computer programming switches dies, suitable for thin-sheet sheet metal processing with many varieties and small batches.
There are many types of punch presses, so how should you choose?
I. Comparison of Applicable Scenarios for Various Types of Punch Presses
| Punch Press Type | Key Features | Suitable Applications | Not Recommended For |
| pneumatic hole punch press punching machine jh21 series | Good rigidity, fast‑speed, pneumatic clutch, large opening size, convenient die change | Punching, blanking, bending; mass production of motorcycle / ATV / agricultural hardware brackets and gaskets | Deep drawing of thick plates, extra‑large workpieces |

II. 4-Step Quick Selection Method
Look at the process (priority) Punching / blanking / bending → JH21 mechanical punch press; drawing, forming, thick plate pressing → hydraulic press; precision small parts continuous production from coil stock → high-speed punch press.
Calculate the tonnage Calculate the punching force according to sheet thickness and shear perimeter, reserve a 30% margin when selecting the model, and do not use it at full tonnage for a long time.
Check the hard parameters (easy to make mistakes) Slide stroke, shut height, and worktable dimensions. The die must match these three items, otherwise the die cannot be installed.
Look at output and automation Small batch, manual loading and unloading: single basic punch press Medium batch: can be equipped with a simple feeding mechanism for semi-automatic production Large-batch coil stock production: punch press + material rack + leveler + feeder as a complete automated line Large-batch sheet production: can be combined with a sheet feeding manipulator to achieve automated operation
After selecting the punch press, how should the die be matched?
● hole punch die for press machine
A punching die belongs to the blanking die category and is installed on a punch and press machine. Its function is to punch round holes, square holes and special-shaped holes in sheet metal. The hole obtained by punching is the finished product, and the small piece punched out is called waste (scrap / slug), which is the opposite of a blanking die (where the blanked part is the finished product).
Basic structure (the complete die set is divided into upper die and lower die)
Punch (punch head):upper die, actively cuts into the sheet metal and determines the inner diameter of the hole; available in circular, square, special-shaped, and small-hole sleeve types.
Die (die block):lower die, with a cutting-edge hole; waste falls downward through the die hole; a blanking clearance is reserved between punch and die.
Stripper plate (stripping plate):spring-driven, presses the sheet metal down first; on the return stroke, it scrapes the sheet metal off the punch to prevent the workpiece from sticking to the punch.
Guide components:guide pillar + guide bushing, to ensure alignment of the upper and lower dies and prevent edge galling.
Die shoe, fixing plate, backing plate, locating pin:for fixing, pressure bearing, and sheet metal positioning.
Working principle
The punch press machine slide drives the upper die downward, and the stripper plate first presses the sheet metal down;
The punch continues to press down, and the material undergoes shear tearing;
When the material has been cut into about 15%–30% of the sheet thickness, fracture separation occurs, and the waste falls through the die;
The slide returns, and the stripper plate strips the sheet metal off the punch, completing one punching cycle.
Die Classification
| Type | Features | Application Scenarios |
| Single‑operation Piercing Die | Piercing only in one stroke; simple structure and low cost | Small‑batch and simple parts; single punch for combined shearing‑punching machine |
| Compound Die | Completes piercing and blanking in one stroke | Gaskets and flanges with high positional accuracy requirements |
| Progressive Die | Strip‑fed material; multi‑station continuous piercing and forming | Mass‑produced sheet‑metal and electronic parts with high efficiency |
| Cam‑driven Side Piercing Die | Converts vertical reciprocating motion into horizontal motion via cams | Side‑wall piercing for tubular and bent parts |
Commonly used die materials (punch / die block)
Cr12MoV / SKD11:the most universal, HRC 58–62, for Q235 and ordinary carbon steel medium-thick plate; the first choice for cost-effectiveness.
DC53:better toughness than Cr12MoV, for stainless steel and small holes prone to edge chipping.
SKH-9 (M2 high-speed steel):for high-frequency stamping and stainless steel, with longer service life.
Cemented carbide (tungsten steel YG8):super wear-resistant, for large-batch thin plate; highly brittle, with high requirements for press rigidity.
Optional TiN/TiCN coating to reduce material sticking and extend service life for stainless steel and aluminum plate.
Core parameter: blanking clearance (unilateral clearance)
Clearance = sheet thickness × clearance coefficient, which directly determines burr size, cutting-edge life and blanking force.
Low-carbon steel Q235: 7.5%–10% of sheet thickness (unilateral)
Stainless steel: 10%–12.5%
Aluminum / copper: 5%–7.5%
Clearance too small: secondary shearing, heat generation and material sticking, punch prone to chipping; clearance too large: large burrs, waste tearing, slug jumping.
Simplified blanking force formula:F = L × t × τ L = punching perimeter, t = sheet thickness, τ = material shear strength.
