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 |

TECHNICAL FEATURES OF THE EQUIPMENT FOR BOLTS COLD PRODUCTION
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.
The rollers provide blanks feeding for small size bolts heading.
Hand wheel control allows setting the length of the KO
Pneumatic type of SACMA blank feeding provides high-speed and stable process of heading.
Punch ejecting mechanism can be installed on request.
Motorised correct mechanism provides stable operation of wire rod fixing (diameter greater than Ø18 mm).
The mechanism of power failure by S-CAM system is controlled by crankshaft horizontally.
Transmitting clicks provide a secure blanks grip
Stop of bolts cold heading equipment occurs automatically in the case of:
- fault,
- the need to clean the blank.
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.
The equipment produces bolts with diameter M3, M4, M5, M6, M8, M10, M12, M16, M20, M22, M24, M27, M30, up to 355 mm.
These products are manufactured on equipment with 2, 3, 4 positional forging stations
