COLD FORMING EQUIPMENT FOR FASTENERS, PARTS AND HARDWARE
General information of cold forming equipment for fasteners, parts and hardware
If you are interested in equipment for fasteners, metal hardware and component parts cold production, we are happy to assist you in choosing the right equipment, we will solve all your problems in realizing your plans and projects.
Many companies use cold heading machines for the production of fasteners, bolts, nuts and special parts and supply them to major companies in the automotive industry such as: Toyota, TATA (India), Honda, Nissan, Hyundai, Mitsubishi, Suzuki, BMW, BENZ, WV, VOLVO and for companies producing motorcycles: Bajaj (India), Hero Honda (India). Also, a large number of special fasteners and parts are used in engineering projects of tAERO Space company for different purposes.
Designing process of metal hardware, fasteners and component parts cold heading traditionally begins with calculating the amount of the final forming position, and further considering the deformation of each part element preliminary blank form is calculated up to the cylindrical blank, cutted from the wire coil. Depending on the calculated degree of metal deformation, changes in the mechanical scheme of total degree of deformation, as well as on technical requirements for specified item (structure, hardness, breaking load etc.), it is determined what chemical, mechanical, physical, technological or special properties deformable metal should have, whether intermediate metal annealing is necessary and what tool is sufficient and for the mass or serial production of fasteners. Make a specification for design and manufacture of equipment. We will offer the best solution to your problem.
Cold Forming: Advantages, Process, and Applications
Cold forming, commonly known as cold heading, offers significant advantages in terms of cost, quality, and performance. This process typically results in a much higher material yield, faster production rates, and superior material properties compared to machining. The cold forming process produces parts at room temperature by forging the material past its elastic limits, resulting in a new shape.
In the cold heading process, wire is taken from a coil, cut to a precise length, and progressively formed into a blank through multiple dies and punches. This produces one finished product per machine cycle. Cold heading allows for the production of complex precision parts at high speeds with minimal or no material waste.
The process involves deforming the original blank by repeated shock loading in stamps. This results in a local increase in transverse dimensions while decreasing the length. The blank is fed into the die by means of a punch and then headed. When a single stroke cannot achieve the desired shape, multi-position machines for heading are used. Cold heading can produce products with transverse parameters of 8-9 quality class (accuracy limit), making this technology suitable for the production of precision parts.
Additionally, you can review our proposed specifications for equipment used in the cold production of fasteners, metal hardware, and component parts. These specifications include the necessary theoretical and technological content for the cold heading process.
