Description

[0002] A leaf spring is composed of several alloy spring leaves of equal width but unequal length. The longest leaf, usually called the main leaf, has ears at both ends. To improve the stress-bearing conditions of the main leaf ears, a common design is to also shape the ends of the second leaf into ears, wrapping them around the outside of the main leaf ears to form an enclosed ear structure.

[0003] The lug-bending process for leaf springs involves bending the ends of the steel leaves into semicircular projections. This structure enhances the spring's strength and durability, and facilitates attachment to the vehicle frame or other components. The quality of the lug-bending process directly impacts the performance and service life of the leaf spring.

This multiple transfer of the steel plate not only reduces processing efficiency but also requires additional unbending operations due to the movement of the steel plate during bending, making the overall process rather cumbersome.

The drive assembly 70 can drive the sleeve 71 to rotate a certain angle so that the steel plate follows the support shaft 720 to rotate a certain angle, and finally a circular protrusion is formed at the end of the steel plate.

[0028] A linkage assembly 5 is provided on the side wall of the limiting assembly 2 , and two pushing assemblies 8 are respectively slidably arranged on both sides of the linkage assembly 5 , and the two pushing assemblies 8 are respectively connected to corresponding driving assemblies 70 .

The first driving member 700 can control the horizontal movement of the first tooth plate 701, and through the cooperation of the first gear 702, drive the shaft sleeve 71 to rotate a certain angle.

[0032] Furthermore, if Figure 2 As shown, the support assembly 72 includes a support shaft 720, a second tooth plate 721 and a second gear 722, wherein one end of the support shaft 720 is slidingly connected to the sleeve 71, a first groove is opened on the outer wall of the support shaft 720, the second tooth plate 721 is arranged in the first groove, and a shell 13 is connected to the sleeve 71.

[0033] It should be noted that, see Figure 7 A blocking block is provided at one end of the support shaft 720 away from the shaft sleeve 71, and a slot is provided on the inner wall of the locking sleeve 73 that cooperates with the blocking block. When one end of the support shaft 720 is inserted into the interior of the locking sleeve 73, the blocking block is located in the slot to lock the support shaft 720 and the locking sleeve 73.

[0034] Furthermore, the second gear 722 is connected to an external drive motor, which can drive the second gear 722 to rotate, and adjust the position of the support shaft 720 through the cooperation of the second tooth plate 721. After the ear is rolled, the support shaft 720 can be quickly retracted into the interior of the sleeve 71, so as not to hinder the switching of the steel plate.

[0035] In one embodiment of the present application, Figure 2 As shown, the abutment assembly 74 includes a plate sleeve 740, a second driving member 741 and a pressure plate 742, wherein both side walls of the plate sleeve 740 are provided with connecting rods 75, and the two connecting rods 75 are respectively arranged on the shaft sleeve 71 and the locking sleeve 73, the second driving member 741 is arranged inside the plate sleeve 740, and the output end of the second driving member 741 is connected to the pressure plate 742, and one end of the pressure plate 742 is slidably connected to the plate sleeve 740.

[0036] In an embodiment of the present application, the second driving member 741 can be an electric push rod or a pneumatic rod. The second driving member 741 can adjust the position of the pressure plate 742 to fit the bent part of the steel plate with the outer wall of the support shaft 720, and drive the support shaft 720 to rotate to drive the bent part of the steel plate to rotate a certain angle, ultimately forming a circular protrusion.

[0037] Furthermore, the connecting rod 75 is an L-shaped rod, which can connect the plate sleeve 740 to the shaft sleeve 71 and the locking sleeve 73 respectively, and drive the plate sleeve 740 and the locking sleeve 73 to rotate, thereby driving the abutment assembly 74 to rotate.

[0038] In one embodiment of the present application, Figure 1 As shown, the limiting assembly 2 includes a carrier 20, a ball screw 21, two first sliders 22 and two limiting plates 23, wherein a first slide groove 200 is provided on the upper surface of the carrier 20, the ball screw 21 is rotatably arranged inside the first slide groove 200, and one end of the ball screw 21 extends to the outside of the carrier 20, the two first sliders 22 are respectively mounted on the ball screw 21, and the first slider 22 is slidably connected to the first slide groove 200, and the two limiting plates 23 are respectively arranged on the corresponding first sliders 22.

[0039] It should be noted that the ball screw 21 is provided with two sections of threads in opposite directions, the two first sliders 22 are respectively arranged on different sections of threads, and when the limit plate 23 abuts against the two side walls of the steel plate, the spring 53 is in a compressed state.

[0040] In one embodiment of the present application, Figure 4 and Figure 6 As shown, the linkage assembly 5 includes a support frame 50, a third gear 51, two third tooth plates 52 and a spring 53, wherein the support frame 50 is arranged on the side wall of the carrier 20, the third gear 51 is arranged on the ball screw 21, the two third tooth plates 52 are respectively engaged with the third gear 51, and the side wall of one of the third tooth plates 52 is provided with a connecting plate 14, and the two ends of the spring 53 are respectively connected to the connecting plate 14 and the side wall of the support frame 50.

[0041] It should be noted that the two third tooth plates 52 are respectively arranged above and below the third gear 51, and the third tooth plates 52 are slidably connected to the support frame 50. Openings are respectively provided on both sides of the support frame 50 to allow the third tooth plates 52 to pass through.

[0042] Furthermore, if Figure 1As shown, the pushing assembly 8 includes a push rod 80 and a second slider 81, wherein two second slide grooves are provided on the upper surface of the processing table 1, the second slider 81 is slidably connected to the second slide groove, the push rod 80 is arranged on the second slider 81, and one end of the push rod 80 is connected to the push block 703, and the other end of the push rod 80 is arranged corresponding to the third tooth plate 52.

[0043] It should be noted that the push rod 80 is a U-shaped rod. When the first driving member 700 is started, it can drive the push rod 80 to move in the direction of the third gear plate 52, and the other ends of the two push rods 80 are respectively set corresponding to the corresponding third gear plates 52. Because the moving directions of the two third gear plates 52 are opposite, the third gear 51 can always be driven to rotate in the same direction, so that the spring 53 is compressed or stretched.

[0044] Specifically, see Figure 6 When the left end of the steel plate is rolled, the first driving member 700 drives the first tooth plate 701 to move to the right, and through the cooperation of the first gear 702, drives the sleeve 71 and the support assembly 72 to rotate counterclockwise. At the same time, the first driving member 700 pushes the push rod 80 to move to the right, and the push rod 80 pushes the third tooth plate 52 below to move to the right, and through the cooperation of the third gear 51, drives the ball screw 21 to rotate counterclockwise, so that the two limit plates 23 move back to back, releasing the limit on the steel plate, so that the steel plate can move to the left. At this time, the spring 53 is in a compressed state.

[0045] When the ear is rolled, the first driving member 700 drives the push rod 80 to move to the left. Under the action of the elastic potential energy of the spring 53, the third tooth plate 52 below moves back to the left, and through the cooperation of the third gear 51, drives the ball screw 21 clockwise, so that the two limit plates 23 move toward each other and re-limit the steel plate.

[0046] Similarly, when the right end of the steel plate is rolled, the first driving member 700 drives the first tooth plate 701 to move to the left, and through the cooperation of the first gear 702, drives the sleeve 71 and the support assembly 72 to rotate clockwise. At the same time, the first driving member 700 pushes the push rod 80 to move to the left, and the push rod 80 pushes the third tooth plate 52 above to move to the left, and through the cooperation of the third gear 51, drives the ball screw 21 to rotate counterclockwise, and the two limit plates 23 move back to back, releasing the limit on the steel plate. At this time, the spring 53 is in a stretched state.

[0047] In one embodiment of the present application, Figure 1 As shown, the folding ear assembly 4 includes a hydraulic rod 40, an upper mold 41 and a lower mold 42, wherein a vertical plate 15 is provided on the upper surface of the processing table 1, the hydraulic rod 40 is installed on the vertical plate 15, and the output end of the hydraulic rod 40 is connected to the upper mold 41, and the lower mold 42 is installed on the processing table 1, and the lower mold 42 cooperates with the upper mold 41.

[0048] It should be noted that the facing surfaces of the upper mold 41 and the lower mold 42 are both arc-shaped surfaces. The hydraulic rod 40 can drive the upper mold 41 to move toward the lower mold 42 to bend the end of the steel plate into an arc-shaped structure, thereby facilitating the ear rolling operation.

[0049] In one embodiment of the present application, Figure 5 As shown, the switching assembly 3 includes two first brackets 30, two second brackets 31, a slide 32, a slide rod 33 and an adjustment plate 34, wherein the upper surface of the processing table 1 is respectively embedded with two second slide modules 6 and a third slide module 9, the two first brackets 30 are respectively arranged on the two side walls of one of the carriers 20, and the first bracket 30 is connected to the slide of the second slide module 6, the slide 32 is arranged on the slide of the third slide module 9, and one end of the second bracket 31 is connected to the other carrier 20, and the other end of the second bracket 31 passes through the slide 32 and extends to the bottom of the processing table 1, the adjustment plate 34 is arranged below the processing table 1, and an adjustment groove 340 is penetrated on the adjustment plate 34, the two ends of the slide rod 33 are respectively connected to the second bracket 31, and the slide rod 33 is slidably connected to the adjustment groove 340.

[0050] It should be noted that the adjustment slot 340 is a trapezoidal structure with a low middle and high ends. The second bracket 31 is slidably connected to the adjustment plate 34. The second slide module 6 and the third slide module 9 can drive the two carriers 20 to move in opposite directions.

[0051] Specifically, when the positions of the two platforms 20 are exchanged, relevant personnel control the second slide module 6 and the third slide module 9 to start, thereby driving the two platforms 20 to move toward each other, and the slide rod 33 slides in the adjustment groove 340. When the slide rod 33 moves from a higher position to a lower position, with the cooperation of the second bracket 31, it drives the platform 20 connected to the second bracket 31 to move downward, so that the two platforms 20 can move up and down in an offset manner, realizing the exchange of the positions of the two platforms 20 without causing motion interference.

[0052] Specifically, when performing the ear rolling operation on the steel plate, the relevant personnel heat the two ends of the steel plate and make them reach a plastic state, and push one of the third tooth plates 52 to move so that the two limit plates 23 move away from each other, and then center the steel plate between the two limit plates 23 in the ear folding work area. Then, the ear folding component 4 can be controlled to start, and the two ends of the steel plate can be pressed into an arc structure using the ear folding component 4.

[0053] After the ear folding is completed, the relevant personnel can control the second slide module 6 and the third slide module 9 to start. With the cooperation of the switching component 3, the bent steel plate is transferred to the ear curling station area, and the steel plate after the ear curling is transferred back to the ear folding station area. At this time, the relevant personnel can easily replace the steel plate in the ear folding station area and continue the ear folding operation. At the same time, the steel plate in the ear curling station area is undergoing ear curling operation.

[0054] Since the ear rolling operation needs to be carried out in sections, this application uses the ear rolling operation of the left end of the steel plate as an example for explanation. First, the relevant personnel controls the first slide module 10 to start, and the first slide module 10 drives the support plate 11 to move to the right, and drives the shaft sleeve 71 and the locking sleeve 73 to move to both sides of the arc structure of the steel plate. At this time, the relevant personnel controls the support assembly 72, and the support shaft 720 extends from the shaft sleeve 71 and is inserted into the locking sleeve 73. Subsequently, the abutment assembly 74 can be controlled to start, so that the pressure plate 742 fits the arc surface of the steel plate, and then the drive assembly 70 can be controlled to start, and the drive assembly 70 drives the support shaft 720 to rotate counterclockwise to make the left end of the steel plate roll into a circle.

[0055] At the same time, the driving component 70 can also drive the pushing component 8 to move to the right, and through the cooperation of the linkage component 5, drive the ball screw 21 to rotate counterclockwise, the spring 53 is compressed, and the two limit plates 23 move back to back, releasing the limit on the steel plate and facilitating the steel plate to move to the left.

[0056] When the ear is rolled, the support shaft 720 is retracted into the sleeve 71. The first slide module 10 then drives the left ear rolling mechanism 7 away from the steel plate. The compressed spring 53 drives the third tooth plate 52 to return, which in turn drives the ball screw 21 to rotate clockwise. The two limit plates 23 move toward each other and limit the steel plate, achieving automatic limit and release of the steel plate. Finally, the ear can be rolled on the right end of the steel plate.

[0057] In summary, the leaf spring lug-rolling equipment of the embodiment of the present application can quickly switch between two platforms without frequently transferring the steel plate, significantly improving the efficiency of lug-rolling. At the same time, it can also automatically release the restrictions on the steel plate during the lug-rolling process, making the operation simpler and faster.
