Description

Technical Field

[0001] The invention relates to the technical field of bending processing of a stabilizer bar, in particular to a tool for local bending processing of a variable diameter stabilizer bar of an automobile. Background Art

[0002] ‌ Stabilizer bar, also known as lateral stabilizer bar, anti-roll bar or balance bar, is an auxiliary elastic element in the automobile suspension system; ‌ Its main function is to keep the car body balanced, especially when the car is turning, due to the centrifugal force, the car body will tilt, the stabilizer bar can counteract the torsion force and reduce the degree of outward deviation of the car, thereby reducing the movement of the suspension system and the sway of the car body. When processing the stabilizer bar, it is necessary to use bending tooling to bend the stabilizer bar;

[0003] The bending tool in the prior art, by fixedly connecting the inclined surface stop block with the pressing mechanism, avoids the phenomenon that the end of the stabilizer bar after processing and the inclined surface stop block are buckled to form a locked wedge due to the fixed setting of the traditional inclined surface stop block, and the stabilizer bar after processing cannot be taken out. At the same time, the seat mechanism can be adjusted according to the stabilizer bar of different lengths, thereby increasing the versatility of the device and greatly expanding the scope of application.

[0004] However, before bending the stabilizer bar, it is often necessary to cut a straight bar of a certain length, and then place the straight bar on the processing tooling for bending. This not only increases the processing steps, but also reduces the processing efficiency. Therefore, there is room for improvement. Summary of the invention

After the first bending seat 38 drives the first bending wheel 39 to perform the first bending on the straight rod, the first bending seat 38 continues to move downward, thereby pushing the driving frame 53 to move downward, driving the fourth spring to compress, and the two bottom ends of the driving frame 53 push the L-shaped plate 52 and the H-shaped plate 48 to move downward as a whole, to drive the through rod 49 to move downward in the driving slot 47, and through the squeezing of the through rod 49 on the groove wall of the driving slot 47, the two groups of driving plates 46 and the pull-out plate 42 are pulled synchronously toward the middle, thereby driving the second bending wheel 43 to perform the second bending work on the two ends of the stabilizing rod at the second bending seat 40, thereby realizing the one-time forming of the stabilizing rod to improve the bending work efficiency.

[0044] The implementation principle of a tooling for local bending processing of automobile variable diameter stabilizer bars in an embodiment of the present invention is as follows: first, the straight rod is directly placed on the placement seat 18 and the placement bar 19, and the cylinder 22 is started to drive the reciprocating plate 29 and the movable plate 23 to move as a whole in the direction close to the switching disk 5, and the movable plate 23 drives the bottom end of the first vertical rod 26 to slide on the left end inclined surface of the guide plate 21, so as to drive the moving blocks 25 on the two moving plates 23 to move in the direction close to each other, thereby driving the two conveying plates 28 to move and clamp onto the straight rod. As the reciprocating plate 29 continues to move, the straight rod on the placement seat 18 can be conveyed to between each group of multiple limit plates 35 of the switching disk 5. When the reciprocating plate 29 drives the bottom end of the first vertical rod 26 to move to the guide When the right end of the plate 21 is reached, the third spring force is used to reset the moving block 25, so that the straight rod part is automatically released after being transported to the switching disk 5, and then the cylinder 22 drives the reciprocating plate 29 to move in the opposite direction, and the guiding effect of the right end of the guide plate 21 on the first vertical rod 26 makes the two conveying plates 28 keep the straight rod released to move in the opposite direction and reset, so as to avoid the conveying plate 28 from bringing the straight rod back on the placement seat 18 during the reverse movement and reset process. In this way, after the conveying plate 28 is reset and the straight rod is cut, the conveying plate 28 can continue to transport the straight rod to the switching disk 5. During cutting, the first hydraulic cylinder 7 on the first bracket 6 is started to drive the lifting seat 8 to move downward. At the same time, the second motor 9 is started to drive the cutting knife 10 to rotate, and the lifting and lowering Before the seat 8 drives the rotating cutting knife 10 to move down to cut the straight rod, the lifting seat 8 drives the pressing block 14 to move down and press against the straight rod to fix the straight rod, and uses the T-shaped rod 13 to drive the first spring 15 to lengthen, and the T-shaped rod 13 moves up on the connecting plate 12, so that after the straight rod is pressed and fixed, the rotating cutting knife 10 can continue to move down to cut the straight rod. After cutting, the first motor 3 is started to drive the switching disk 5 on the rotating column 4 to rotate, and the straight rod cut to the switching disk 5 is transported to the bottom of the fixed frame 36, and the upper and lower limit plates 35 of the switching disk 5 are switched to the placement seat 18, so that the straight rod can continue to be transported to the switching disk 5. When bending, the second hydraulic cylinder 37 is started to drive the first bending seat 38 to move down. The straight rod is bent for the first time in the groove 32. After the first bending seat 38 drives the first bending wheel 39 to perform the first bending on the straight rod, the first bending seat 38 continues to move downward, thereby pushing the driving frame 53 to move downward, driving the fourth spring to compress, and the two bottom ends of the driving frame 53 push the L-shaped plate 52 and the H-shaped plate 48 to move downward as a whole, to drive the through rod 49 to move downward in the driving groove 47. Through the squeezing of the through rod 49 on the groove wall of the driving groove 47, the two groups of driving plates 46 and the pull-out plate 42 are pulled synchronously toward the middle, thereby driving the second bending wheel 43 to perform the second bending work on the two ends of the stabilizing rod at the second bending seat 40, thereby realizing the one-time forming of the stabilizing rod, so that the bending processing of the stabilizing rod can be realized, and the work efficiency is higher.
