Application of punching machine.
1. The hydraulic punch machine is specially use for metal raw materials stretch/ tensile and deep drawing stamping. Such as pot, bowl, cup, vase, plate, barrel, water tank, wash basin, dishes and cookware etc.
2. The press machine is widely use for metal sheet stretching, forming and straightening.
3. This machine also suitable for different kinds of materials, like metal, stainless steel, copper, aluminum, brass, alloy, steel, iron and so on.
How to use the stretching punching machine.
1. The up and down cylinders move at the same time.
2. Fixed the metal raw materials and mold on the work table.
3. Pull down the up cylinder slowly, so that the material was formed. The under cylinder slowly down back, to hold the workpiece.
4. Coating stretch oil on the workpiece while working, to prevent scratching and damage the workpiece during stretching.
5. After deep drawing, remove the up cylinder tensile axis firstly, then move the under cylinder upward to top out the workpiece, at last take out the workpiece and completed.
6. Stretched within 500mm depth.
Characteristic of deep drawing stamping machine.
1. Stretching: The hydraulic stamping machine is specially use for metal raw materials stretch/ tensile and deep drawing stamping.
2. Stretched within 500mm depth.
3. Wide range of uses: Widely use for metal sheet stretching, forming and straightening.
4. Save costs & Environmentally friendly: Oil as the power of the press machine can be recycled.
5. High quality: The main hydraulic and electrical components are used internationally renowned brands.
6. Easy to operate.
7. Stable: The stamping part are fixed by four columns, which can reduce the shake during pressing. So that reducing the impact on the finished product.
8. Security: The punching machine equipped with photoelectric protection device. If the required pressure for your product exceed the press machine can withstand, the machine will self-protection, and stop punching.
9. Less noise.
