Technical Field

[0001] This utility model relates to the field of spring correction technology, and in particular to a spring correction device. Background Technology

[0002] Spring straightening refers to the process of repairing springs that have been deformed or no longer meet specifications, restoring them to their original shape, size, and performance. Springs may suffer permanent deformation or other problems during manufacturing due to material defects, improper processes, or excessive loads during use, requiring straightening to restore their function. However, existing spring straightening devices cannot heat the springs. Before straightening, the springs must be placed in a heating furnace to soften them before being transferred to the straightening mechanism. This process is time-consuming, labor-intensive, affects the efficiency and effectiveness of spring straightening, and poses safety hazards.

[0003] Therefore, a spring straightening device has now been developed that can heat and straighten springs, saving manpower and improving the efficiency and safety of spring straightening. Utility Model Content

The straightening table 2 is connected to the upper side of the support frame 1. The lower sides of the left and right sides of the support frame 1 are trapezoidal for stable placement. The first hydraulic cylinder 3 is connected to the middle of the support frame 1. The conical straightening rod 5 is connected to the telescopic end of the first hydraulic cylinder 3. The placement plate 4 is connected to the middle of the straightening table 2. The conical straightening rod 5 passes through the placement plate 4. The heating component and the straightening component are provided on the straightening table 2.

[0020] like Figure 1 and Figure 3 As shown, the heating assembly includes a first mounting base 6, a first motor 7, a first lead screw 8, an eddy current generator 9, and an eddy current coil 10. The first mounting base 6 is connected to the upper left side of the correction table 2. The first motor 7 is connected to the upper side of the first mounting base 6. The first lead screw 8 is connected to the output shaft of the first motor 7. The first lead screw 8 is rotatably connected to the first mounting base 6. The eddy current generator 9 is threadedly connected to the first lead screw 8. The eddy current generator 9 is slidably connected to the first mounting base 6. The eddy current coil 10 is connected to the right side of the eddy current generator 9.

[0021] like Figure 1 and Figure 4 As shown, the correction assembly includes a second mounting base 11, a second motor 12, a second lead screw 13, a transmission block 14, a second hydraulic cylinder 15, and a pressure plate 16. The second mounting base 11 is connected to the upper right side of the correction table 2. The second motor 12 is connected to the upper side of the second mounting base 11. The second lead screw 13 is connected to the output shaft of the second motor 12. The second lead screw 13 is rotatably connected to the second mounting base 11.

[0022] When using this utility model, firstly, place the support frame 1 in the spring straightening area, then place the spring to be straightened on the placement plate 4. After placement, start the second motor 12 to drive the second lead screw 13 to rotate, causing the transmission block 14 to move downwards, which in turn drives the second hydraulic cylinder 15 to move downwards, so that the pressure plate 16 contacts the upper side of the spring to limit the spring. Then, start the first motor 7 to drive the first lead screw 8 to rotate, causing the eddy current generator 9 and the eddy current coil 10 to move. Then, start the eddy current generator 9 to provide high-frequency or medium-frequency AC power, so that the eddy current coil 10 heats the spring. After the spring softens, start the first hydraulic cylinder 3 and the second hydraulic cylinder 15 to insert the conical straightening rod 5 into the spring to straighten it. After straightening, retract the conical straightening rod 5, then move the pressure plate 16 and the eddy current coil 10 away from the spring, and remove the spring. This achieves the effect of heating and straightening the spring, saving manpower, and improving the efficiency and safety of spring straightening.
