DUAL-STEEL WIRE CONVEYING APPARATUS AND SPRING COILING MACHINE HAVING SAME
Document Type and Number:
WIPO Patent Application WO/2022/007086
Kind Code:
A1
Abstract:
A dual-steel wire conveying apparatus (100) and a spring coiling machine (1). The dual-steel wire conveying apparatus (100) comprises a steel wire switching frame (140), a first wire feeding wheel (120), and a second wire feeding wheel (130); the steel wire switching frame (140) can move in a left-right direction to drive a first steel wire (111) and a second steel wire (112) to move in the left-right direction; the first wire feeding wheel (120) has a first circumferential groove (121); the second wire feeding wheel (130) has a second circumferential groove (131); the second wire feeding wheel (130) and the first wire feeding wheel (120) can be close to or far away from each other in the radial direction; when the second wire feeding wheel (130) and the first wire feeding wheel (120) are close to each other, the first circumferential groove (121) and the second circumferential groove (131) are opposite to clamp the first steel wire (111) or the second steel wire (112). The second wire feeding wheel (130) and the first wire feeding wheel (120) are close to or far away from each other along the second wire feeding wheel (130) and the first wire feeding wheel (120) to clamp or release the first steel wire (111) or the second steel wire (112), and the positions of the first steel wire (111) and the second steel wire (112) are controlled by controlling the steel wire switching frame (140) to move left and right. Thus, dual-steel wire conveying is achieved, the structure is simple, and dual-steel wire switching is convenient.
