[0026] To make the objectives, technical solutions and advantages of the present invention clearer and more understandable, the following describes the technical solutions of the present invention clearly and completely in conjunction with specific embodiments and with reference to the accompanying drawings. Obviously, the described embodiments are some, but not all, of the embodiments of the present invention. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without making creative efforts fall within the scope of protection of the present invention.

[0027] Combined with Figure 2 and Figure 3 , this embodiment provides an integrated machine for spring clip marking and forming, including a mounting plate 1 fixed in the vertical direction. Two support members 2 are provided on the mounting plate 1. The support members 2 include a support plate 21 perpendicular to the mounting plate 1 and a punch 22 at one end of the support plate 21 close to the mounting plate 1. The heights of the support plates 21 on both sides are the same. A pressure rod 23 capable of moving along the length direction of the support plate 21 is provided on the support plate 21. Both ends of the spring clip rod 3 can be respectively placed on the support plates on both sides. The spring clip rod 3 can automatically stay on the side close to the punch. An upper die 4 and a lower die 5 for spring clip forming are further provided on the mounting plate 1 above and below the support member 2 respectively.

[0028] This implementation is applied to the heated spring bar 3. The spring bar 3 is placed on the two-sided support plates 21 through the clamping jaws. The two ends of the spring bar 3 are pressed by the pressure rods 23. The convex film 22 is provided with embossed marks. The spring bar 3 contacts the convex die 22 to complete the marking work at both ends. Then the pressure rods 23 leave. The spring bar 3 automatically remains in contact with the two-sided convex films 22 and will not roll. The upper die 4 and the lower die 5 perform a forming operation on the spring bar 3 to obtain a formed spring bar with the marks on the outer sides of both ends, meeting the product requirements.

[0029] Further, the surface of the end of the support plate 21 close to the convex die 22 is inclined downward, so that the spring bar 3 automatically remains in contact with the convex die 22 and will not rotate. Refer to Figure 5 , the end face of the pressure rod 23 in contact with the spring bar 3 is set as an arc surface to increase the contact surface of the pressing and improve the marking effect.

[0030] Refer to Figure 3 , the two pressure rods 23 are fixedly arranged on a sliding seat 24. The two sides of the sliding seat 24 are respectively in sliding fit with a slide rail 25. The end of the sliding seat 24 away from the mounting plate 1 is fixedly connected to the telescopic end of a cylinder 26. The entire sliding seat 24 is driven to slide and press the spring bar 3 through the telescopic movement of the cylinder 26.

[0031] Combined with Figure 4 , two chutes 28 are further arranged on the sliding seat 24. The convex die 22 is slidably arranged in the chutes 28. One end of the convex die 22 is provided with a pre-tightening spring 281. The end of the pre-tightening spring 281 is fixedly connected to the end of the chute 282. During the marking process, the pre-tightening spring 281 makes the convex die 22 have a certain gap with the end of the chute 282. When the convex die 22 contacts the spring bar 3, the convex die 22 can gradually press the spring bar 3. The spring bar 3 is pre-tightened by the pre-tightening spring 281. When the pre-tightening spring 281 is compressed to the limit position, the chute 28 continues to move to push the convex die 22 to press out marks on the spring bar 3, completing the marking process. The pre-tightening spring 281 can ensure that the spring bar 3 will not roll during the marking process and ensure the marking quality.

[0032] Refer to again Figure 3 , baffles 27 perpendicular to the spring bar 3 are respectively arranged on the two-sided support plates 21. The two ends of the spring bar 3 are supported by the support plates 21 and are between the two-sided baffles 27. Thus, when the spring bar 3 is released by the clamping jaws, it can prevent the two ends of the spring bar 3 from deviating from the support plates 21 and affecting the subsequent marking and forming.

[0033] Combined with Figure 6 and Figure 7, the upper die 4 includes a first pushing arm 41 and two second pushing arms 42 on both sides of the first pushing arm 41. The first pushing arm 41 and the second pushing arms 42 are both arranged in the vertical direction. The lower die 5 includes two upper positioning columns 51, two lower positioning columns 52 and two third pushing arms 53 which are symmetrically distributed. The first pushing arm 41 is arranged along the central axis of the lower die 5. The distance between the two upper positioning columns 51 is less than the distance between the lower positioning columns 52. The third pushing arm 53 is located below the lower positioning column 52, and the third pushing arms 53 can move centrically towards each other.

[0034] The process of the upper die 4 and the lower die 5 provided in this embodiment cooperating to form the elastic strip is as Figure 8 shown. Before the first pushing arm 41 squeezes the elastic strip rod 3 downward into the two upper positioning columns 51, after the elastic strip rod 1 is bent, the two second pushing arms 42 push the two ends of the elastic strip rod 1 downward to rotate around the upper positioning column 51. Then, the third pushing arms 53 extend out to push the two ends of the elastic strip rod 1 respectively to rotate around the lower positioning columns 52 to form an elastic strip structure. For elastic strips of other structures, the structures of the upper die 4 and the lower die 5 and the positions of each component can be adaptively set according to the specific structure. For the specific structure of the forming die, reference can be made to the description in the patent application with the publication number CN103418653A.

[0035] One end of the first pushing arm 41 facing the elastic strip rod 3 is set as a U-shaped structure and the end face is semi-circular. A roller is respectively fixed at the end parts of the second pushing arm 42 and the third pushing arm 53. The wheel surface of the roller is semi-circular. The telescopic direction of the third pushing arm is inclined upward, pointing from below the outside of the lower positioning column 52 to between the lower positioning columns 52 to prevent the lower positioning column 52 from affecting the forming of the elastic strip.

[0036] The distances of the first pushing arm 41, the second pushing arms 42, the third pushing arms 53, the upper positioning columns 51 and the lower positioning columns 52 from the mounting plate 1 are respectively determined according to the position of the convex die 22. The column surfaces of the upper positioning columns 51 and the lower positioning columns 52 are respectively in contact with the surface of the elastic strip rod 3. The upper positioning columns 51 and the lower positioning columns 52 are slidably arranged along the axial direction on a concave die 54. A pressing block 55 capable of contacting the concave die is installed at the end of the sliding seat 24. The upper positioning columns 51 and the lower positioning columns 52 can move axially and contract below the surface of the concave die 54. The pressing block 55 contacts the concave die 54 to complete the step of pressing the elastic strip. After that, the pressing block 55 follows the sliding seat 24 to leave the concave die 54, and the formed elastic strip falls naturally for collection.

[0037] Specifically, during processing, the spring bar 3 is placed on the pallet 21. The pressing rod 23 moves along with the sliding seat 24, pushing the two ends of the spring bar 3 against the punch 22 to complete marking. At this time, a previously formed spring bar is sleeved on the lower die 5. The pressing block 55 moves along with the sliding seat 24 and extends to abut against the previously formed spring bar. Then, the upper positioning post 51 and the lower positioning post 52 contract inward and leave the spring bar. The pressing block 55 continues to move to press the spring bar into the inner part of the concave die 54 to form a spring bar structure with a side surface as shown in Figure 9 Figure Figure 9 . Thus, the marking and forming operations of the spring bar can be completed by a set of equipment. Moreover, while the spring bar 3 is being marked, the previous spring bar can be bent and formed, simplifying the production steps and improving the production efficiency.

[0038] The above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit it; although the present invention has been described in detail with reference to the foregoing embodiments, those of ordinary skill in the art should understand that: they can still modify the technical solutions recorded in the foregoing embodiments, or perform equivalent replacements on some of the technical features; and these modifications or replacements do not make the essence of the corresponding technical solutions deviate from the spirit and scope of the technical solutions of the various embodiments of the present invention.
