Description

TECHNICAL FIELD

[0001] The utility model relates to tungsten wire processing technical field more specifically, relate to a kind of tungsten wire passive discharging frame. BACKGROUND

[0002] In tungsten wire industry, there is a coil forming process. In order to improve production efficiency during production, it must be produced in a coil, with a length of several kilometers. However, the product is 100 meters long and must involve coil forming. Currently, the coil forming pay-off device used in the tungsten wire industry is a shaft type pay-off rack. This type of pay-off device has the following problems: the shaft hole is easily worn out, the fork is often damaged, and the top cone screw needs to be tightened when the coil is wound. First, it increases the labor intensity of employees. Second, the tension is difficult to control, which can cause the product to drop during the coil forming process, resulting in unqualified products. Third, the coil length cannot be stopped in time, causing the products on the coil to be loose, leading to knotting and wire breakage, and increasing the rate of short ends.

[0003] The existing patent with the patent number CN201751348U discloses a wire device, specifically a magnetic powder tension pay-off rack for electric wires and cables. It is suitable for coil forming and pay-off of electric wires and cables. It includes a base frame with lifting supports at both ends. The lifting supports are characterized by having a gas cylinder at one end, a gas cylinder needle on the extension shaft of the gas cylinder, a fork needle at the corresponding position on the other end of the lifting support, a rotating shaft of the fork needle connected to a synchronous rotating wheel, and a synchronous rotating wheel connected to a magnetic powder motor through a belt. The fork needle is equipped with a brake device. It solves the problems of high labor intensity, difficult tension control, and difficulty in stopping the existing pay-off device.

During the alignment process, the wire coil is too heavy, making it difficult to move left and right, and the labor intensity is too high, affecting work efficiency. UTILITY MODEL CONTENTS
