PECULIARITIES OF BOLTS PRODUCTION EQUIPMENT CONFIGURATION

Machines peculiarities in comparison with machines of other companies

Mehanism RG design material Design, material of ordinary companies
     
Basic frame Material FCD-60 alloyed ductile iron (Japan)
It has a certificate of quality of the United States in Southeast Asia.
Cast iron 20-25 is cheaper and lower-strength that worse provides strength and stability of the machine during its operation
Crankshaft It was manufactured using a new process and technology homogenized nitriding and polishing It was made by cheaper process of homogenization. 
Crankshaft socket Made from a special aluminum alloy.Patent. Made of bronze (less durable and fast-wearing)
The hollow cutting knife Special Jern Yao patent, easily removed Complex process of shooting
Punch ejecting mechanism Cam-roller type specially designed for high precision
Cam-roller type standard type
Punch holder Hardened carbide SKD-11 Without hardening
Serviceability of punch ejecting mechanism Easy to maintain without taking out of the machine. Must be removed from the machine for maintenance.
Idle time of machine.
Internal self-examination of the machine Automatic analysis of the static and dynamic stress  Without this feature.
Gear Polished. Japan Metal. The gear is made in China
Distribution of lube oil The increased size of the pipeline, promotes good and uniform distribution of oil  The standard system
The accuracy of the machine in the manufacture of products The accuracy of movement within the main ejector of 50mm with accuracy of less than 0.02 mm Inaccuracy more than 0.03 mm
Tool In the company there is a special team for tools and technological process design. It reduces the number of tool units for the production of different products on the same machine.   The company does not have such team for designing tools and processes.
Spare parts The stock of spare parts in the storage of the factory, which ensures fast delivery, if necessary Not the total volume of stock, long time to order and manufacturing
in China.
The cost of spare parts One of the lowest on the market The high cost of parts
Electrical system Imported, CE standard Standard
Electrical system design Design and assembly of manufactured exclusively in Jern Yao factory All is done by subcontractors
Main slide block With copper socket for machine tools 24B Series and more  Without it.
Electrical parts and assembly The design, import and assembly are made exclusively by Jern Yao Partial use of subcontractors
Machine operating Easy to operate and work, saving a lot of time with help of quick-change mechanism (which is a great advantage in the production of several types of products under its small numbers)  Standard on the market
Without these functions

Main plate

The frame provides absolute stability and a straight forward process of heading. Made of cast iron with nodular graphite grade JIS FCD 55, which ensures its durability.Holders of the matrix are made of stainless steel grade FCD 70 are arranged parallel to each other and can be adjusted independently.


Blank feeding mechanism

The rollers provide blanks feeding for small size bolts heading.


Length ejector regulator

Hand wheel control allows setting the length of the KO


Blank pneumatic feeding mechanism

Pneumatic type of SACMA blank feeding provides high-speed and stable process of heading.


Punch ejecting mechanism

Punch ejecting mechanism can be installed on request.


straightening mechanism

Motorised correct mechanism provides stable operation of wire rod fixing (diameter greater than Ø18 mm).


The mechanism of power failure

The mechanism of power failure by S-CAM system is controlled by crankshaft horizontally.


Transmitting clicks

Transmitting clicks provide a secure blanks grip


Brake engine

Stop of bolts cold heading equipment occurs automatically in the case of:

  • fault,
  • the need to clean the blank.


Pneumatic clutch and brake system

Pneumatic clutch and brake system maintain flywheel in torsion movement.



Taiwan Metiz Alliance provides equipment with 2, 3, 4, 5, 6, 7 positional forging stations for bolts production of different shape, diameter and length. The equipment supports three modes of blanks feeding, including spring, synchronous and pneumatic modes, fitted with pneumatic clutch and brake, speed change is controlled by an inverter.
