Description

Technical Field

[0001] The utility model relates to the technical field of spring coiling machines, in particular to a spring coiling machine with an adjustable spring hose coiling wire diameter. Background Art

[0002] Spring coiling machines with adjustable wire diameter for spring hoses are mainly used to manufacture and process spring hoses. The special feature is that they can adjust the wire diameter. Through automation and precise control, spring coiling machines can quickly and accurately complete the coiling of spring hoses, greatly improving production efficiency. The adjustable wire diameter function enables the spring coiling machine to produce spring hoses with different wire diameters according to different needs, thereby meeting the needs of various application scenarios.

[0003] In the existing technology, the device inserts the steel wire deep into the space between two conveying rollers so that the steel wire enters the diameter adjustment frame, and then drives the grinding disk to move through the screws distributed around to adjust the diameter of the wire to a suitable size, so that the steel wire is adjusted to a suitable wire diameter, and the adjusted steel wire is curled into a spring shape through a spring forming device. However, in actual use, when adjusting the position of the grinding disk, the device needs to turn the screws around one by one to adjust it, which makes it impossible for the staff to quickly and synchronously adjust the grinding disks around, and it is easy to increase the tediousness of the staff's work. When the device grinds the steel wire through the upper, lower, left and right grinding disks, due to the different diameters of the steel wire, it is easy for the grinding disk to not fully cover the outer surface of the steel wire, so that the steel wire of the suitable wire diameter cannot be evenly ground. Therefore, it is necessary to improve a spring coiling machine with adjustable wire diameter for spring hose winding. Utility Model Content
