Description

Technical Field

[0001] The utility model relates to the technical field of correction, in particular to a spring steel wire correction device. Background Art

[0002] Different types of spring steel wire have different production methods, and their common characteristics are that they require certain strength, high toughness and good spring coiling performance. Spring steel wire is a kind of steel wire used to make springs or wire profiles. Depending on the purpose of the spring, it is used in different places.

[0003] For example, a spring steel wire correction device with the authorization announcement number "CN220127476U" first achieves the effect of extruding and correcting the spring steel wire through the correction mechanism, thereby solving the problem of bending of the spring steel wire. The second motor is started to rotate to drive the third roller to rotate, and the steel wire on the third roller is transported to between the second roller and the first roller through rotation. Then the first motor is started, and the first motor rotates to drive the first roller. A first gear is fixed on one side of the first roller. The rotation of the first gear drives the meshing second gear. The rotation of the second gear drives the first roller. The steel wire is rotated and extruded and corrected between the rotating second roller and the first roller, so that the steel wire becomes straight from being bent. However, the spring steel wire correction device has a limiting function only in the up and down directions, but not in the left and right directions, which easily causes the spring steel wire to jump left and right. The straightened spring steel wire is not convenient for operators to collect, thereby increasing manual labor. At the same time, due to the movement of the distance between the second roller and the first roller, the spring steel wire correction device cannot perform correction work when other thicker or thinner spring steel wires need to be corrected. The operator needs to switch to other compatible machines for processing, which increases work limitations. Utility Model Content

[0028] Working principle:

[0029] When using a correction device to correct the spring wire:

[0030] Preparation process:

[0031] First, open the opening and closing plate 11, and put the material roller wrapped with the spring steel wire on the surface of the sliding roller 8. Then, place one end of the spring steel wire between the limit block 10 and the moving block 9, start the power supply of the first hydraulic cylinder 2, and the telescopic end of the first hydraulic cylinder extends to drive the moving block 9 to slide along the slide groove processed on the inner wall of the box body 1. When the moving block 9 and the limit block 10 are both pressed against the surface of the spring steel wire, turn off the power supply of the first hydraulic cylinder 2, and then pass the other end of the spring steel wire through the first clamping claw 304 and the second clamping claw 305, and then through the upper roller 6 and the lower roller 4, and finally pass through the through hole processed on the right side of the box body 1.

[0032] Spring wire limiting process:

[0033] First, start the power supply of the second hydraulic cylinder 302. The telescopic end of the second hydraulic cylinder 302 extends to drive the double-sided rack 303 to slide upward along the slide groove processed on the first shell 301, thereby driving the first clamping claw 304 and the second clamping claw 305 to gradually move away from the slide groove processed on the first shell 301. When the spring steel wire can be placed between the first clamping claw 304 and the second clamping claw 305, the telescopic end of the second hydraulic cylinder 302 is retracted. When the surfaces of the first clamping claw 304 and the second clamping claw 305 are both in contact with the surface of the spring steel wire, the power supply of the second hydraulic cylinder 302 is turned off to prevent the spring steel wire from jumping left and right, making it more convenient for operators to collect.

[0034] The operator rotates the bolt 707 counterclockwise to move the bolt 707 away from the vertical rod 704, and starts the power supply of the second motor 702. The output shaft of the second motor 702 rotates clockwise to drive the cam 703 to rotate, thereby driving the vertical rod 704 to slide downward along the slide groove processed on the fixed block 705 and the second shell 701, and at the same time stretching the spring 706. The vertical rod 704 moves downward to drive the upper roller 6 to move downward. When the surfaces of the upper roller 6 and the lower roller 4 are tightly fitted with the surface of the spring steel wire, the power supply of the second motor 702 is turned off, and the operator rotates the bolt 707 clockwise to make the surface of the bolt 707 press against the surface of the vertical rod 704, so that spring steel wires of different thicknesses can be corrected, thereby reducing working limitations.

[0035] Spring wire correction process:

[0036] Start the power supply of the first motor 5 to make the output shaft of the first motor 5 rotate counterclockwise, and the bent spring steel wire is straightened through the extrusion of the upper roller 6 and the lower roller 4, and slides out from the through hole processed on the right side of the box body 1 for use by the operator.
