Abstract

The invention belongs to the technical field of cable manufacturing processes, and particularly relates to a production process of a foaming core wire of a coaxial cable with excellent performance. The production system for lifting an echo coaxial cable foaming core wire comprises an active pay-off rack, a conductor wire storage rack, a front traction device, an inner skin gluing device, a coating foaming device, a cooling device, a drying device, a detection device, a direct-current spark machine, a rear traction machine and an automatic take-up and winding displacement sub-plate, wherein the conductor wire storage rack is arranged behind the active pay-off rack, the front traction device for transmitting a coaxial cable through forward power and the rear traction machine for transmitting the coaxial cable through backward power are arranged behind the conductor wire storage rack, and the inner skin gluing device and the coating foaming device are arranged between the front traction device and the rear traction machine. The cooling device is arranged behind the coating foaming device, the cooling device is used for cooling the cable after inner skin gluing and coating foaming, and a drying device is arranged behind the cooling device for drying.

Description

technical field [0001] The invention belongs to the technical field of cable manufacturing technology, and in particular relates to a production technology of a coaxial cable foam core wire with excellent performance. Background technique [0002] At present, the general cable factory conductor pay-off racks are passive pay-off racks, the conductors are easily strained and deformed, resulting in poor echo; most of the cable factory conductors are customized according to the size of the customer's finished conductors and then directly produced on the production line , if there is a defect in the conductor, it is very easy to have poor conductor echo; at the same time, it is easy to be affected by the tension change during the operation of the machine to affect the conductor wire diameter, resulting in unqualified low-frequency attenuation; prolonging the production cycle and increasing production costs.

Problems solved by technology

[0002] At present, the general cable factory conductor pay-off racks are passive pay-off racks, the conductors are easily strained and deformed, resulting in poor echo; most of the cable factory conductors are customized according to the size of the customer's finished conductors and then directly produced on the production line , if there is a defect in the conductor, it is very easy to have poor conductor echo; at the same time, it is easy to be affected by the change of tension during the operation of the machine, resulting in unqualified low-frequency attenuation; prolonging the production cycle and increasing the production cost

[0003] At the same time, the conductor tension process of the production line is very meticulous. So far, the front and rear tractors of the coaxial cable factory have relied on the induction of the tension guide wheel to control the running tension of the core wire. The conductor needs to pass several small guide wheels, so the operation process will be greatly improved Increased risk of poor echo performance
