[0002] The automobile muffler is a part used to reduce the noise generated by the engine of a motor vehicle when it is working. It is usually composed of two muffler structures, which are installed behind the three-way catalytic converter and the automobile exhaust pipe respectively. Therefore, when installing and docking, a connecting flange is required to ensure a stable connection. This type of connecting flange is usually formed by stamping equipment and has higher hardness and better stability.

[0003] When the automobile muffler connecting flange is formed by stamping equipment, the shape of the connecting flange is mostly a diamond structure. When loading the material, it is necessary to rely on manual labor to put the mold material from the mold. Since the existing stamping equipment is usually in continuous operation and the operator is close to the stamping structure, when the operator loads the material for a long time, there is a risk of being pinched by the stamping mechanism due to misoperation due to fatigue, resulting in low safety when the equipment is used; in addition, the stamping die and punch on the existing stamping equipment are installed in designated positions. Before loading and unloading, it is necessary to wait for the stamping step to be completed, and the punch and die must be separated before loading and unloading can be carried out, resulting in low efficiency of the equipment when loading and unloading.

[0024] As Figures 1 to 4 shown, the stamping forming equipment for the connecting flange of the automobile muffler in this embodiment includes an equipment body 1. A stamping mechanism 17 is installed inside the equipment body 1. A convex module 2 is clamped at the output end of the stamping mechanism 17. There are two guide plates 3 below the convex module 2. One end of one of the guide plates 3 is fixedly connected with a material placing plate 5. A slideway 15 is opened in the middle of the material placing plate 5. A pushing plate 6 is slidably connected inside the slideway 15. An electric push rod 16 is arranged on one side of the pushing plate 6;

[0025] Inside the guide plate 3, there is a concave module 7. On the other side of the guide plate 3, there is a rotating rod 14. On the outer wall of the rotating rod 14, two connecting rods 12 are fixedly connected. One end of the connecting rod 12 is fixedly connected with a long strip 10, and one end of the connecting rod 12 is fixedly connected with a short strip 11. At one end of the rotating rod 14, a second gear 19 is engaged, and on the outside of the second gear 19, a first gear 18 is engaged.

[0026] Specifically, other components for ensuring the normal operation of this automotive muffler connecting flange stamping forming equipment are also installed inside the equipment body 1. The stamping mechanism 17, the electric push rod 16, and the rotating motor 13 are all controlled by a control system, enabling the three electrical devices to cooperate to complete the actions of feeding, stamping forming, and discharging. The convex module 2 can only move up and down in the vertical direction relying on the stamping mechanism 17. The function of the guide plate 3 is to limit the sliding direction of the concave module 7 on the equipment, enabling the concave module 7 to smoothly slide to the directly below of the convex module 2 to complete the stamping forming action, and then slide out of the equipment along the guide plate 3 for the discharging action. The material placing plate 5 is arranged on one side of the equipment body 1, enabling the operator to keep a relatively long distance from the stamping mechanism 17 on the equipment, thereby improving the safety of this equipment during use. The function of the slideway 15 is to enable the push plate 6 to push the concave module 7 to slide along the guide plate 3 according to a predetermined route. The function of the electric push rod 16 is to make the push plate 6 slide in the slideway 15. The number of concave modules 7 is multiple, and the size of each concave module 7 is the same. Moreover, the front and back surfaces of each concave module 7 are smooth surfaces, enabling each concave module 7 to be pushed after contacting the left and right two concave modules 7 after mutual contact, thereby realizing the conveying movement of the concave module 7 inside the equipment and improving the feeding and discharging efficiency of this stamping forming equipment. The function of the rotating rod 14 is to drive the connecting rod 12 and the attached structures on the connecting rod 12 to rotate, enabling the concave module 7 that has completed the stamping forming to be unloaded from the guide plate 3, and at the same time facilitating the subsequent movement of the concave module 7 towards the rotating rod 14 direction, thereby realizing the rapid discharging of the equipment. Each group of connecting rods 12 has four, and the four connecting rods 12 are fixedly arranged around the outer wall of the rotating rod 14. When the rotating rod 14 rotates, the long strip 10 and the short strip 11 can continuously remove the concave module 7 that has completed the stamping from the guide plate 3, thereby facilitating the acceleration of the discharging speed of the equipment. After the first gear 18 and the second gear 19 are engaged, the rotating rod 14 can be continuously rotated, enabling the concave module 7 to continuously perform the discharging action, thereby saving the waiting time for the equipment to feed and discharge.

[0027] Furthermore, chutes 4 are opened in the middle of both guide plates 3. On both side walls of the concave module 7, sliding strips 8 are fixedly connected. The concave module 7 is slidably connected to the guide plate 3 through the sliding strips 8 and the chutes 4. The sliding strips 8 are in the shape of long strips 10 and are adapted to the chutes 4, enabling the concave module 7 to smoothly slide along the guide plate 3 to the directly below of the convex module 2 for the stamping forming action.

[0028] Furthermore, the length of one guide plate 3 is the sum of the lengths of the loading plate 5 and the other guide plate 3. The guide plate 3 and the loading plate 5 are both fixedly connected to the equipment body 1. The concave module 7 can slide in from one side of the loading plate 5, so that the slide bar 8 on one side of the concave module 7 is engaged with the slide groove 4, and the end of the slide bar 8 on the other side is docked with the port of the slide groove 4 on the other guide plate 3, thereby facilitating the transmission movement of the concave module 7 along the guide plate 3.

[0029] Furthermore, a notch 9 is provided at the top of the two guide plates 3 away from the loading plate 5, and the concave module 7 is movably connected to the long strip 10 through the notch 9. The function of the notch 9 is to facilitate the separation of the slide bar 8 of the concave module 7 from the end of the slide groove 4, but it can also stay on the guide plate 3 and wait for the long strip 10 to be moved, thereby realizing the removal of the concave module 7 from the equipment.

[0030] Furthermore, a rotary motor 13 is fixedly mounted on a side wall at the other end of the other guide plate 3 , and an output end of the rotary motor 13 is engaged and connected with the first gear 18 . The rotary motor 13 can drive the first gear 18 to rotate after being energized, thereby providing power for the rotation of the first gear 18 .

[0031] Furthermore, the rotating rod 14 is rotatably connected to the two guide plates 3 through the first gear 18 and the second gear 19. The rotating rod 14 can rotate between the two guide plates 3 under the action of the first gear 18 engaging the second gear 19, thereby realizing the rotation of the connecting rod 12 on the rotating rod 14 and the auxiliary structure on the connecting rod 12, so as to improve the unloading efficiency of the equipment.

[0032] Furthermore, the electric push rod 16 is fixedly installed at the bottom of the equipment body 1, and the output end of the electric push rod 16 is engaged with the bottom end of the push plate 6. After being energized, the electric push rod 16 can push the push plate 6 to perform reciprocating linear motion in the slide 15, so that the push plate 6 can push the concave module 7 to move toward the other end of the guide plate 3, thereby realizing the loading action of the mold material on the concave module 7.

[0033] The usage method of this embodiment is as follows: When using this stamping equipment for the connecting flange of the automotive muffler, it is necessary to first connect the stamping equipment to an external power source, and then push the concave die block 7 along the material placement plate 5 towards the guide plate 3. When the slide bar 8 on one side of the concave die block 7 is engaged with the chute 4 on one of the guide plates 3 and the front surface is in contact with the back surface of the push plate 6, and at the same time the end of the slide bar 8 on the other side of the concave die block 7 is docked with the port of the chute 4 on the other guide plate 3, the electric push rod 16 will start and drive the push plate 6 to slide along the slide way 15, so that the push plate 6 pushes the concave die block 7 into the middle of the two guide plates 3, and the pushed concave die block 7 is in contact with the front surface of the previously pushed concave die block 7, enabling the previously pushed concave die block 7 to move to directly below the convex die block 2. When the concave die block 7 is pushed to directly below the convex die block 2, the stamping mechanism 17 will push the convex die block 2 downward, so that the die material on the concave die block 7 is stamped into shape. With the continuous pushing of the subsequent concave die block 7, the concave die block 7 that has completed the stamping action will be pushed to the notch 9 at the end of the guide plate 3. Then the rotating motor 13 will start and drive the first gear 18 to rotate, so that the first gear 18 meshes with the second gear 19 to rotate, driving the rotating rod 14 and the connecting rod 12 on the rotating rod 14 to rotate, so that the long strip 10 on the connecting rod 12 picks up the concave die block 7 that is suspended by the guide plate 3 and removes it from the equipment in a rotating manner. When the concave die block 7 rotates to the vertically upward position, the concave die block 7 will be stuck between the long strip 10 and the short strip 11, and at the same time the die material and waste in the concave die block 7 will be separated from the concave die block 7.

[0034] Finally, it should be noted that the above are only the preferred embodiments of the present invention and are not used to limit the present invention. Although the present invention has been described in detail with reference to the foregoing embodiments, for those skilled in the art, they can still modify the technical solutions described in the foregoing embodiments, or perform equivalent replacements for some of the technical features. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
