Multi-station Cold Heading Machine

Our multi-station cold heading machine is a six-station synchronous forming equipment upgraded to meet the processing demands for special-shaped parts, flange parts and non-standard parts in the fastener industry. In current fastener production, complex parts processed step-by-step on single-station equipment require multiple process transfers, which is time-consuming and labor-intensive. Moreover, repeated clamping easily causes precision deviations and ultimately reduces the finished product yield. This multi-station cold heading machine integrates cutting, pre-heading, finish heading, punching and trimming processes into one single unit. After wire feeding, no intermediate transfer is needed, and complete finished products can be produced in one pass. It greatly shortens the processing flow and avoids precision loss caused by multi-process transfers.

The equipment adopts an independent mold adjustment mechanism, allowing separate parameter adjustment for each station. The mold spacing can be flexibly configured between 100mm and 165mm according to part complexity. Equipped with an independent cam-driven rear ejection system with an ejection length up to 75mm, it prevents material jamming or ejection deformation during demolding even for deep-hole parts and complex inner cavity structures. A real-time forming force monitoring system comes as standard, with high-precision sensors installed at each station. Real-time force data of all stations is displayed on the screen during operation, enabling rapid positioning of stations with abnormal stress during process debugging to drastically shorten mold trial cycles. In formal production, it delivers timely early warnings to avoid mass defective products.

Designed with distributed forging force, the single-station maximum forging force can be flexibly configured from 220 tons to 600 tons. Matched with a 220HP main motor, the production speed reaches 60–120 pieces per minute, and the slide stroke is adjustable from 110mm to 150mm. Sufficient power output is guaranteed for every station during multi-station complex forming, eliminating insufficient forming force at rear stations despite adequate power at front stations. The lubrication system features independent station oil supply. A 3HP intelligent lubrication system automatically adjusts oil supply based on load of each station: increasing oil volume for heavy-load stations to ensure lubrication and reducing oil volume for light-load stations to cut consumption. It extends equipment service life while controlling daily consumable costs.

We have 26 years of experience in cold heading equipment R&D and manufacturing. Every unit undergoes a 48-hour no-load running test before delivery to confirm stable operation of all moving components prior to shipment. If you have specific product processing requirements, you may send samples or molds to our factory in advance. Our technical team will complete mold debugging on-site, produce qualified samples with the equipment, and arrange delivery only after your confirmation. The equipment can be directly put into production upon power connection at your facility, eliminating time costs for on-site debugging.
