COLD FORMING MACHINERY FOR MICRO FASTENERS

1-Die 2-Blow Micro Cold Heading Machine for Micro Screw

Сost-effective 1-Die 2-Blow Cold Heading Machines for high precision manufacturing of standard micro fasteners with wire diameters from 0.5 to 5.3 mm.

The machines are equipped with a protective cover to prevent contamination of the interior with oil and dust.

• Designed for short, small diameter fasteners with a thin head.
• Die transfer without gripper: ideal for short products.
• Bush cut-off construction for a perfectly flat surface even with hard materials.
• Separately operated punches for faster and easier setup.

1-Die 2-Blow Cold Heading Machines are suitable for wire diameters from Ø0.5mm to Ø5.5mm.

With wire diameters less than Ø4.5 mm, material transmission method without clamp over-die is used.

For wire diameter Ø5.5mm we offer 2 different material transfer methods according to product length specifications, and there are fixture over-die and no-clamp over-die.

What is a non-clamp over-die?

Round shear break => material ejection => 1 blow transfer to 1 die

2-Die 3-Blow Micro Cold Forming Machines

2 dies and 3 forming stations allow the production of relatively complex micro-parts. On such a machines, it is possible to effectively produce micro fasteners with a wire diameter of 0.5 - 4.5 mm. These machines is equipped with a protective cover to prevent contamination of the interior with oil and dust.

• Suitable for cold heading short fasteners with a small diameter and a thin head.
• Die-transfer without gripper ideal for short workpieces.
• Bush cut-off design for a perfectly flat surface even when working with hard materials.
• Separate operating punches for faster and easier setup.
• The separated die holder can adjust the concentricity independently.
• The material-receiving function can prevent material collision and the 2 blow/ 3 blow can set monitoring accuracy independent.
• The Double D.K.O. device (optional) can improve the roundness and fullness of the head forming.

The RG-1305 Micro cold forming machine is suitable for very precise and short workpieces. The material transfer mode is designed without clamping over the die, through materials with two punches to transfer materials from the first die to the second die after the completion of the three-die production. The ideal vacuum feeding device instantly transfers the finished product to the collection box, which can prevent splashing, smearing, lack of product, material leakage and mixing problems.

Offered 2 different material transmission methods for different choices according to the different length specifications of the product. RG-1310F has fixture over-die and RG-1310 has no-clamp over-die.

The separated die holder can adjust the concentricity independently. The material-receiving function can prevent material collision and the 2 blow/3 blow can set monitoring accuracy independent.

Technical Specification

Multi-Station Micro Formers

• High-precision mechanism designed for cold heading very small precision parts. It has high rigidity for long-term accurate maintenance and can ensure the overall assembly accuracy within 10 µm or less.

• The machine can control the die block pitch accuracy to 5µm or less.
• A structure is used that can adjust the finger's transfer pitch with higher accuracy.

4-Die 4-Blow Micro Former RG-4P

The machine is designed for complex cold forming operations required for the manufacture of complex micro-parts. 4 forming stations make it possible to produce a wide range of shapes with a wire diameter of 0.8 - 3.0 mm. The machine is equipped with a protective cover to prevent contamination of the interior with oil and dust.

• For advanced complex micro forming operations.
• Clamp die transfer.
• Flexible transfer options: translational, rotating, turning.
• Lightweight clamp design provides secure gripping of very small parts down to 0.7mm in diameter.

6-Die 6-Blow Micro Former RG-6P

The machine is designed for complex cold heading operations required for the manufacture of very complex micro-parts from 0.8 - 3.0 mm. The machine is equipped with a protective cover to prevent contamination of the interior with oil and dust.

• 6 forming stations make it possible to produce a wide range of shapes with a wire diameter of 0.8 - 3.0 mm.
• High precision, low vibration and noise.
• Flexible advanced production of various types of micro fasteners.
• The die cassette change system allows changing in 10 minutes for increased productivity.
• High production flexibility: for new types of products, only the replacement of the die cassette is required.

Technical Specification

Cold heading machine for bi-metal RG-05MB

This 2-Die 3-Blow types of cold forming machine is for silver joint double material and double round shear break.

This can achieve better cut surface quality, and the material can be made of material whose outer diameter within minimum 0.7mm. The shortest cut length is 0.7L, which can be used for customers for their applications.

This model saves the expensive cost of precious metal (silver) materials and provides customers with higher profit margins.

Double DKO System with additional stroke increase fullness for the finished products without adding material and tool modification.

Technical Specification

Combined micro cold heading and micro thread rolling machine RG-05H

One of the important features of this machine is the vacuum transport system. From the cold heading station, the blanks are immediately transferred to the drum of a rotary feeder using an advanced vacuum transport system. Further, the workpieces are continuously fed to the thread rolling station to form the thread.

Technical Specification

Optional Accessories for Micro Cold Heading Machines

PKO System

• After punch completion, at the same time as the main slide retreats, PKO engages.
• Cam-driven punch knock-out system.
• Suitable for a wide range of die designs.
• With the front PKO device installed, the second die is finished stamping, and the main sliding seat is ready to be retracted at the same time for PKO, which effectively prevents die sticking.

HMI Control Panel

• User-friendly 7-inch touch panel.
• Error notification & record feature.
