Description

Technical Field

[0001] The utility model relates to the technical field of diameter-changing mechanisms, in particular to a diameter-changing mechanism of a spring machine. Background Art

[0002] A spring machine is a machine used to process metal wire into specific shapes and sizes. The working principle of the existing spring machine is to send the wire to the machine body through a wire feed rack, straighten it, feed it to the machine processing area, curl it and cooperate with the wire feed shaft to form the angle, and then form it into various angles through the rotation of the turret shaft. Finally, it is cut by a hydraulic shear to complete the entire processing process. Since the position where the wire needs to be cut and the angle of bending are different, different fixed paths are required. The existing wire entering the spring machine will enter the curling and diameter reducing mechanism through the conveying structure for bending. The clamping structure provided on the curling and diameter reducing mechanism will wear out after bending for a long time. The existing clamping structure is usually fixed and integrated, which is not convenient to replace. The existing bending and diameter reducing mechanism performs reciprocating motion during bending, which will generate high temperature during long-term work, which will greatly affect the processing of the spring machine.

[0003] Therefore, it is necessary to provide a new diameter-changing mechanism for a spring machine to solve the above technical problems. Utility Model Content

Multiple groups of exhaust ports 7 are opened on the inner upper end of the air inlet 6 on both sides of the turntable groove 3.

[0031] It should be noted that after a prolonged bending and diameter-changing operation, the bolt 17 can be unlocked from the bolt hole 16 by manually rotating the handle 18. The replacement seat 15 can then be manually removed from the turntable 14 and re-inserted into the turntable 14. The bolt 17 penetrates the replacement seat 15 to the bolt hole 16 at the lower end. The handle 18 is then rotated to rotate the bolt 17 to engage the bolt hole 16, securing the replacement seat 15. This allows for quick replacement of the replacement seat 16 and bending block 19, facilitating subsequent bending and diameter-changing operations. After the turntable 14 has repeatedly moved for a long time, power and control signals are transmitted to the fan 12 via the wire 21, blowing air from outside into both sides of the turntable slot 3 and out through the exhaust port 7, thereby cooling the turntable and preventing overheating from affecting the bending and diameter-changing operation.

The wire enters the diameter-changing mechanism through the conveying mechanism, and the wire enters the wire groove. It is stably moved to the turntable 14 through the conveying wheel 8 and the limiting wheel 9. The rotating motor 13 is controlled to rotate repeatedly by transmitting power and control signals through the wire 21, driving the turntable 14 and the bending block 19 at the upper end to bend and reduce the diameter of the end of the wire, and then the wire is cut off by the cutting mechanism. After the turntable 14 moves repeatedly for a long time, power and control signals are transmitted to the fan 12 through the wire 21 to blow the outside air into both sides of the turntable groove 3, and then the exhaust port is exhausted. 7 is discharged, thereby realizing the cooling of the turntable to prevent overheating from affecting the bending and diameter-changing operation. After a long period of bending and diameter-changing operation, the handle 18 provided can be manually rotated to drive the bolt 17 to release the lock of the bolt hole 16, and the replacement seat 15 can be manually pulled out from the turntable 14.
