Embodiment Construction

[0030] Such as figure 1 , 2 , 3, and 4, firstly calculate the elastic modulus of the enameled wire in the enamelling machine furnace according to the high temperature test results, and the sample wire used in the high temperature test is 0.47mm and 0.14mm self-adhesive wire. The enameled wire during the baking and painting process is always pulled by the traction wheel to generate strain (stretch). For the elastic body, the relationship between stress and strain is shown in the following formula:

[0031] σ = Eε

[0032] where σ: stress, E: modulus of elasticity, ε: strain

[0033] Test the elastic modulus of self-adhesive enameled wire with a conductor diameter greater than 0.2mm. Firstly, the high-temperature tensile test is carried out on a relatively thick 0.47mm self-adhesive wire to obtain the corresponding basic data:

[0034] After testing, after complete annealing, the elastic modulus E1 of enameled copper wire coated with paint film at a temperature of 20°C is 8...

Abstract

The invention relates to equipment for changing the gradient of a traction wheel of a fine line mould and improving the operation rate. A lacquering part is provided with a lower lacquering furnace and an upper lacquering furnace; idler pulleys are respectively arranged at the rear ends of the lower lacquering furnace and the upper lacquering furnace; traction wheels are respectively arranged at the rear ends of the lower lacquering furnace and the upper lacquering furnace; and the inclination of each traction wheel is 0.06-0.08 percent. Optimally, the inclination value of the traction wheel is 0.07 percent.

Description

technical field [0001] The invention relates to equipment modification for enameled wire mold coating with a conductor diameter below φ0.2mm, in particular to a device for changing the inclination of the traction wheel of the thin wire mold to improve the utilization rate. Background technique [0002] Felt paint is generally used when painting round wires with a conductor diameter less than 0.2mm in China. We know that when using felt paint to manufacture enameled wires, there are problems such as unsatisfactory roundness and uneven paint film caused by temperature differences between day and night. Products with high precision requirements will be difficult to apply. For this reason, mold coating must be used; and the biggest problem of mold coating for wires with a conductor diameter less than 0.2mm is wire breakage. How to reduce the wire breakage problem during the wire drawing process, is currently to be resolved. There are many factors that lead to disconnection, the...
