Problems solved by technology
When the welding wire produced by the existing unloading reel is used on a high-speed production line, a new wire ball needs to be replaced within a production cycle (22.5 hours), which not only increases the number of joints, but also reduces production efficiency; at the same time, high-speed operation is easy to cause wire wrapping

Embodiment 1
[0034] The method for determining the diameter of the unloading reel used in high-frequency resistance welding copper wire production equipment specifically includes the following steps:
[0035] (1) Determine the initial value d1 of the diameter of the unloading reel;
[0036] d1=60vt / 3.14n, where n is the total number of coils formed by the unloading reel, V is the line speed of the canning production line, t is the running time of the canning production line,
[0037] Determine the values of n, V and t, and calculate the initial value d1 of the diameter of the unloading reel;
[0038] The line speed of the original can production line is 70M / min. According to the line speed of 70M / min and the height of the coils, the total number of coils per coil is about 48000, and the total length of the coils with a diameter of 620mm is 93446.4m, which is just right. It runs for one day (the effective time is 22.5 hours), that is, there is no need to replace the coil during the one-d...

Abstract
The invention discloses a high-frequency electric-resistance-welded copper wire production equipment wire-unloading disc and a wire-unloading disc diameter determining method. The high-frequency electric-resistance-welded copper wire production equipment wire-unloading disc is positioned and supported via a rack, and the diameter of the wire-unloading disc is 896-900 mm. The high-frequency electric-resistance-welded copper wire production equipment wire-unloading disc diameter determining method specifically comprises the following steps: determining the diameter initial value d1 of the wire-unloading disc, wherein d1=60vt / pi n, n is the total coil number formed on the wire-unloading disc, v is the linear speed of a can production line and t is the operation time of the can production line; determining the value of n, v and t, calculating the wire-unloading disc diameter initial value d1; and based on d1, the rack dimension of the high-frequency electric-resistance-welded copper wire production equipment wire-unloading disc, and the starting moment centrifugal force F of the wire-unloading disc, collecting an integral number of d1, and determining the target value d of the high-frequency electric-resistance-welded copper wire production equipment wire-unloading disc diameter. According to the technical scheme, the production demands of a high-speed can production line are satisfied, the joint-joining frequency is substantially reduced and the can production efficiency is substantially improved.
Description
technical field [0001] The invention relates to the field of metal can welding wire production equipment, in particular to a high-frequency resistance welding copper wire production equipment unloading reel and a method for determining its diameter. Background technique [0002] At present, the diameter (inner diameter) of the high-frequency resistance welding copper wire pay-off group commonly used in the domestic canning industry is 620mm. This size is the diameter of the high-frequency resistance welding copper wire manufacturer's production equipment unloading reel. In the past, the line speed of the metal can production line was generally 70M / min. According to the line speed of 70M / min and the height of the coil, the total number of coils per coil was about 48,000, and the total length of the coil with a diameter of 620mm was 93446.4 M, it can run for exactly one day (the effective time is 22.5 hours), that is, there is no need to replace the coil within one day's opera...
