[0002] The production process of a small-sized four-way wire drawing machine is pay-off (passive), single drawing, flaw detection, joint drawing, and wire taking-up. The principle of passive pay-off is to pull the wire coil through the wire drawing machine's reel pulling force, and the wire coil then drives the turntable to work, realizing passive pay-off. Due to the problems of the coil shape, coil shape, and disordered wire, the speed of the wire drawing machine reel taking-up is difficult to match with the speed of the pay-off machine, which is easy to cause problems such as enlarged coils and broken wires during operation.

[0013] The present invention will be described in further detail below in conjunction with the accompanying drawings.

[0014] like Figure 1 , 2 As shown, a novel tension regulating device for a wire drawing machine in this embodiment includes a tension frame 1, a well-shaped roller 2 is arranged on the inlet side of the tension frame 1, and three wire passing wheels are arranged in sequence on the outlet side of the well-shaped roller 2: a first wire passing wheel 3, a second wire passing wheel 4 and a third wire passing wheel 5. The wire passes through the well-shaped roller 2, then passes from the top of the first wire passing wheel 3 to the bottom of the second wire passing wheel 4, and then passes from the top of the third wire passing wheel 5 to the single-head wire drawing machine. A vertically arranged damping cylinder 6 is arranged on the tension frame 1, and the extended end of the damping cylinder 6 is connected to the second wire passing wheel 4. The damping cylinder 6 drives the second wire passing wheel 4 to move vertically. When the wire tension increases, the damping cylinder 6 moves upward, driving the second wire passing wheel to move upward synchronously; when the wire tension decreases, the damping cylinder 6 moves downward, driving the second wire passing wheel to move downward synchronously. The tension of the wire is adjusted by the reciprocating motion of the damping cylinder, so that the wire is always in a relatively tensioned state.

[0015] Two protective nylon plates (not shown in the figure) are arranged on the side of the tension frame 1, and the protective nylon plates are arranged between the first wire passing wheel and the second wire passing wheel, and between the second wire passing wheel and the third wire passing wheel. The protective nylon plates protect the wires and prevent the wires from colliding with the tension frame and being scratched.

[0016] like Figure 3 As shown, the wheel grooves of the wire passing wheel are all V-shaped grooves. A stopper 7 is arranged above the first wire passing wheel to prevent the wire groove from being de-grooved and scratched during the production process, thereby ensuring the quality of the product.

[0017] The above-mentioned well-shaped roller is processed by spraying tungsten carbide on the surface and then grinding, so that the surface roughness is high to prevent the wire from being scratched.

[0018] Workflow: After the wire coil is unwound, the passive pay-off machine leads the wire through the well roller, then passes from the top of the first wire wheel to the bottom of the second wire wheel, and then passes through the top of the third wire wheel, and then leads the wire to the single-head wire drawing machine, flaw detector, joint drawing machine, wire take-up machine, etc. During production, as the reel of the subsequent wire drawing machine rotates to provide tension, the passive pay-off machine rotates under the tension to pay off the wire, and a constantly changing buffer force is provided through the damping cylinder, so that the wire will never break or enlarge the loop due to tension or relaxation.

[0019] The present application has a simple structure, and the damping cylinder can adjust the wire tension, so that the wire is always kept in a tensioned state, thereby avoiding wire breakage and enlarged loops.

[0020] In addition to the above embodiments, the present invention also includes other implementation modes. Any technical solutions formed by equivalent transformation or equivalent replacement should fall within the protection scope of the claims of the present invention.
