[0024] In order to make the objectives, technical solutions and advantages of the present invention more clear, the present invention will be further described in detail below with reference to the accompanying drawings.

[0025] Example 1

[0026] See also Figure 1-6Embodiment 1 provides a method for processing the flat end of a stabilizer rod, which can adopt the processing system of the stabilizer rod disclosed in Embodiment 2, and the method includes: when processing one end, the flat end support block 18 is laid down, and one end of the rod material 10 is processed. When processing the other end, the flat end support block 18 is erected, and the position of the longitudinal slide plate 24 is adjusted forward and backward to allow the flat end support block 18 and the positioning structure 7 to move synchronously so that the processed end is placed flat on the top of the flat end support block 18, and the positioning structure 7 is adjusted or not adjusted to adapt to the length change of the rod material 10 (the length will become longer), and the other end of the rod material 10 is processed. The processing process of the rod material 10 is as follows: the relay conveying structure conveys the rod material 10 from the feeding structure to the flattening die 3, the punching die 4, the trimming die 5 and the discharging structure 6 in sequence, and the rod material 10 is roughly positioned at the feeding structure (specifically, the lifting notch 16 on the right) by an adjustable stroke pneumatic ejector of the positioning structure 7, and the rod material 10 is precisely positioned at the flattening die 3 by another adjustable stroke pneumatic ejector of the positioning structure 7. Among them, the relay conveying structure includes at least four lifting units (five in this embodiment) to process multiple rod materials 10 at the same time. The flattening die 3, the punching die 4 and the trimming die 5 are located on the lifting block of the same die-casting molding device 1 to realize the flattening, punching and trimming of three rod materials 10 at the same time.

[0027] Among them, participants Figure 1-4 , the relay conveying structure in the embodiment of the present invention reciprocates the rod material 10 in the left-right and vertical directions. When the lifting unit is in a low position, the rod material 10 falls into the corresponding mold, feeding structure or discharging structure 6. When the lifting unit is in a high position, the rod material 10 leaves the mold or feeding structure upward. A loading station and a rough positioning station are arranged side by side on the feeding structure. The loading station is located on the left side of the rough positioning station for loading; of course, loading and rough positioning can be performed at the same station. Correspondingly, a lifting notch 16 is provided on the feeding structure, and four lifting units are provided on the relay conveying structure. The loading station, the rough positioning station, the flattening mold 3, the punching mold 4, the trimming mold 5 and the discharging structure 6 are arranged in equal intervals from left to right and the spacing between them is L1. The distance of the left-right reciprocating movement of the relay conveying structure is L2. Five lifting units are provided on the relay conveying structure, and the distance between two adjacent lifting units is L3, L1=L2=L3. When the relay conveying structure is on the right side, the first lifting unit (counting from left to back, the same below) is located at the rough positioning station, and the last lifting unit is located directly in front of the discharge structure 6. When the relay conveying structure is on the left side, the first lifting unit is located at the loading station, and the last lifting unit is located directly in front of the trimming mold 5.

[0028] Specifically, see Figure 1-4The five lifting units in the embodiment of the present invention are aligned, the first lifting unit includes two lifting plates 13 arranged side by side and capable of supporting the rod material 10, and the remaining four lifting units each include two pneumatic clamps 14 arranged side by side and capable of clamping the rod material 10, and the eight pneumatic clamps 14 can be driven synchronously.

The variable support seat 8 and the side positioning seat 9 are respectively located in the front and rear of the relay conveying structure. The side positioning seat 9 is located at the rear of the rod material 10 for positioning the rod material 10 on the left and right sides. The variable support seat 8 is used to support the front end of the rod material 10. A support wheel 11 for supporting the rod material 10 is provided in the front or rear of the first side positioning seat 9 along the left and right directions to facilitate front and rear adjustment during positioning. The variable support seat 8 includes a support 17 and a flat end support block 18 and a rod support block 19 arranged side by side in the front and back directions thereon. The support 17 is provided on the longitudinal slide 24, and the rod support block 19 is used to support the rod material 10 (regardless of processing one end or the other end) and is flush with the corresponding mold. The flat end support block 18 is rotatably provided on the support 17. When the flat end support block 18 is erected, it is higher than the rod support block 19 (the height must ensure that the flat end is horizontally placed on the top of the flat end support block 18).

[0030] Specifically, see Figure 1-4 The working process of the relay conveying structure in the embodiment of the present invention is as follows: the reciprocating mechanism 12 moves upward, and the first lifting unit lifts the rod material 10 on the feeding structure upward; at the material rod 10, all the pneumatic clamps 14 synchronously clamp the corresponding rod material 10 and move it upward away from the supporting structure (and leave the mold at the same time). After the lifting unit moves to the high position, the reciprocating mechanism 12 moves to the right, and the five lifting units drive the corresponding rod material 10 to move to the right. After the lifting unit moves to the right, the reciprocating mechanism 12 moves downward, and when the rod material 10 reaches the adjacent upper part of the mold, all the pneumatic clamps 14 are released synchronously, and the rod material 10 falls into the supporting structure (and falls into the mold or the lifting gap 16 on the right side) or the discharging structure 6. After the lifting unit moves to the low position, the reciprocating mechanism 12 moves to the left.

[0031] Specifically, see Figure 1-4The top of the feeding structure in the embodiment of the present invention is provided with two lifting notches 16 that can support the rod material 10, forming a loading station and a rough positioning station respectively.

Before the two adjustable stroke cylinders 21 are extended, the ejector plate 23 on the left side is located in front of the ejector plate 23 on the right side. After the two adjustable stroke cylinders 21 are extended, the top plate 23 rests against the front end of the rod material 10, and the top plate 23 on the left is located in front of the top plate 23 on the right. At this time, the rear end of the rod material 10 corresponding to the top plate 23 on the right is just located in the flattening mold 3.

At this time, the rotation shaft is located at the upper part of the long strip hole. When the flat-end support block 18 is standing up, it is arranged vertically, its bottom is placed at the bottom of the rotation groove, and its front side is against the limiting protrusion. At this time, the rotation shaft is located at the lower part of the long strip hole.

[0035] Example 2

[0036] See also Figure 1-6 Embodiment 2 provides a processing system for a stabilizer bar, which includes a die-casting device 1 and an auxiliary processing device in front of it. The die-casting device 1 is provided with three molds (including an upper mold and a lower mold) from left to right. The three molds are flush and are respectively a flattening mold 3, a punching mold 4 and a trimming mold 5 from left to right. The three molds are arranged at equal intervals and the distance between adjacent molds is L1. The upper molds are all arranged on the lifting block of the die-casting device 1, and the lower molds are all arranged on the workbench 2. That is, the die-casting device 1 can perform flattening, punching and trimming processing on three rod materials 10 at the same time when it is lifted and lowered once. The auxiliary processing device includes a feeding structure (for feeding), a discharging structure 6 (for discharging), a positioning structure 7, a relay conveying structure and three supporting structures, etc. The three supporting structures are respectively located in front of the three molds and each includes a variable support seat 8 and a side positioning seat 9 arranged side by side in front and back. The side positioning seat 9 is located at the rear of the rod material 10 for positioning the rod material 10 on the left and right sides; the variable support seat 8 is used to support the front end of the rod material 10, and it has two forms. A support wheel 11 (a ring groove matching the rod material 10 is provided on its circumferential surface) for supporting the rod material 10 is provided in the left and right directions in front or rear of the first side positioning seat 9 (the front in this embodiment) to ensure the accuracy of precise positioning.

[0037] Among them, the relay conveying structure includes a reciprocating mechanism 12 capable of left-right and vertical reciprocating motion and five lifting units arranged side by side and at equal intervals on it. The relay conveying structure is located between the variable support seat 8 and the side positioning seat 9 and its left-right motion distance is L2. The distance between two adjacent lifting units is L3. The first lifting unit (counted from left to right, the same below) includes two lifting plates 13 arranged side by side in front and back and capable of supporting the rod material 10. The remaining four lifting units all include two pneumatic clamps 14 arranged side by side in front and back and capable of clamping the rod material 10. The second, third and fourth lifting units are respectively facing the three molds, and the eight pneumatic clamps 14 are driven synchronously.

When the lifting unit is in a low position, the lifting unit is lower than the variable support seat 8, the feeding structure and the discharge structure 6, and the processing end of the rod material 10 (placed on the support structure) can fall into the corresponding mold. When the lifting unit is in a high position, the lifting unit is higher than the variable support seat 8, the feeding structure and the discharge structure 6, and the processing end of the rod material 10 (leaving the supporting structure) can leave the lower mold of the corresponding mold upward. The relay conveying structure continuously reciprocates left and right and vertically, allowing the rod material 10 to go from the feeding structure from left to right to the three molds and the discharge structure in sequence. The movement process of the relay conveying structure is: the lifting unit rises, the lifting unit moves to the right, the lifting unit falls, and the lifting unit moves to the left; when the lifting unit rises to the rod material 10, it starts to clamp the rod material 10, and only releases the rod material 10 when it falls to the adjacent upper part of the supporting structure.
