Abstract
A method and a plant for manufacturing fasteners, in particular screws, along an automated production line; the method comprising the following steps: feeding the raw material made of titanium; heating the raw material to a predefined temperature; cutting one or more pieces of a predefined length, in succession, from the heated raw material; deforming plastically each piece by means of one or more finishing stations, so as to obtain a fastener; heating, during the deforming step, the material that passes through each workstation to a predefined temperature; wherein the material manipulated along the production line during the feeding, heating, and deforming steps is automatically transported along the production line.
Claims16
A method for manufacturing fasteners along a production line of a plant;
- the production comprising a plurality of stations;
- the method comprising the following steps:
- at a feeding station, feeding raw material having a tensile strength equal to or greater than 800 MPa;
- at a heating station, heating the raw material to a predefined temperature so as to obtain hot raw material;
- wherein, the temperature reached is not such as to allow the formation of a surface layer of oxide on the hot raw material;
- at a cutting station, cutting the hot raw material so as to separate one or more pieces of a predefined length, in succession, by means of a die/punch system that is configured to continuously cut and feed each piece to a successive finishing station;
- at one or more finishing stations plastically deforming each piece by means of one or more finishing stations, so as to obtain a fastener;
- wherein said material is automatically advanced along the production line, by means of advancement means, during the feeding, heating, cutting and deforming steps;
- the plant comprising a centralised control system which is connected to each of said stations, so that each of said station can be regulated in real time, according to a type of fasteners to be produced or to data detected in real time along the production line by means of sensors;
- wherein said steps are carried out simultaneously by the plant, so as to obtain a continuous and automatic production of fasteners that are the same or different in terms of geometry and/or size.
A plant for manufacturing fasteners and comprising a production line along which are located:
- a feeding station for raw material;
- a heating station configured to heat the raw material up to a predefined temperature so as to obtain hot raw material;
- wherein, the temperature reached is not such as to allow the formation of a surface layer of oxide on the raw material;
- a cutting station comprising a die/punch system that is configured to continuously cut the hot raw material so as to separate one or more pieces of a predefined length, in succession and feed each piece to a successive intermediate finishing station;
- one or more finishing stations, each of which is configured to plastically deform each piece so as to obtain a fastener;
- heating means configured to heat the raw material at said heating station to said predefined temperature;
- advancement means that automatically transport the material along the production line;
- a control system which is connected to each of said stations, so that each of said station can be regulated in real time, according to a type of fastener to be produced or to data detected in real time along the production line by means of sensors.
