CP-25-II Rubber Waterproof Membrane Pneumatic Punching Machine

Description

Product Introduction:

This machine is designed for rubber factories and research institutions to punch standard rubber test specimens and similar materials prior to tensile testing. It features pneumatic control, offering convenient, fast, and effortless operation.

Technical Specifications:

Parameter item	Parameter value
Itinerary Scope	20mm～60mm
Workbench dimensions	260mm×230mm
External dimensions	380mm×260mm×590mm
Working pressure	0.4 MPa–0.6 MPa (air source optional)
Weight	50kg

Brief structural description:

The film processor mainly consists of: a base, a pressing head, a coupling assembly, a machine body, a manual three‑position five‑way valve, a cylinder, a locking nut, and an adjusting nut. (See Figure 1.)

Rotate the handle of the manual three‑position five‑way valve; the air pressure within the cylinder drives the piston rod in a reciprocating motion, causing the punch to press down and shear the test specimen.

Instructions for use:

1. Connect the air supply line and adjust the pressure to 0.4 MPa.

2. Place the plastic PP board (provided free of charge) on the workbench, and position the specimen on the flat surface of the board.

3. Place the required cutter on the specimen, ensuring that the center of the cutter aligns with the center of the indenter.

4. Operate the handle of the manual three‑position five‑way valve; at this point, the plunger will descend, allowing you to punch out a standard test specimen. If the stroke is insufficient, adjust it as follows: position the handle in the middle, loosen lock nut 7, and then raise the adjusting nut to modify the plunger stroke.

5. Our facility manufactures cutting blades in accordance with national standards such as GB/T 528 and GB/T 529; custom-made blades are also available upon request based on your drawings.
