Description

Technical Field

[0001] This utility model relates to the field of stamping die technology for automotive parts processing, specifically to a stamping die for a vibration damping tower support plate. Background Technology

[0002] Stamping dies are special process equipment used in cold stamping to process materials into parts. They are called cold stamping dies. Stamping dies for automotive parts processing are high-precision and high-efficiency production tools, widely used in the automotive manufacturing industry. They process metal sheets into the required parts shapes through stamping, shearing, stretching and other processes. Stamping dies are usually made of die steel, which has the characteristics of high temperature resistance and wear resistance, ensuring the dimensional accuracy and surface quality of the parts.

[0003] For example, referring to the case "A Stamping Die for a Car Hinge Reinforcing Plate Partition" (publication number CN215786164U), this utility model discloses a stamping die for a car hinge reinforcing plate partition. It includes a base, support columns at the four corners of the base's bottom, a controller on one side wall of the base, a fixing plate between the tops of four slide rails, and sliding sleeves fitted onto each of the four slide rails. The pressure plate has four rectangularly distributed threaded holes, and the top of the fixing plate has four rectangularly distributed and inverted motors. Each motor's output end has a lead screw that penetrates the fixing plate and extends out of it. The lead screw passes through the threaded hole and is threadedly connected to it. The bottom of the pressure plate is connected to a die via four rectangularly distributed pressure sensors. A lower die plate is located at the center of the top of the base, directly below the die. This design not only uses intelligent mechanical operation to replace manual operation, greatly improving stamping accuracy, but also strictly controls the pressure of the die by setting pressure sensors, preventing damage.

[0004] Although the aforementioned stamping die is equipped with a pressure sensing device to control the stamping pressure of the die, when the actual stamping structure performs stamping operations on the partition, the stamping structure and the partition will form a groove or hole that matches the stamping structure. The stamping structure is placed in this groove or hole. Therefore, when the stamping structure is reset, friction is easily generated due to the contact area between the stamping structure and the groove or hole, which can cause the partition to move or change its position, thus easily affecting subsequent stamping operations.

[0005] Based on this, this utility model designs a stamping die for a vibration damping tower support partition to solve the above problems. Utility Model Content

[0028] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this utility model. All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without creative effort are within the scope of protection of this utility model.

[0029] The present invention will be further described below with reference to the embodiments.

[0030] In some embodiments, please refer to the appendix to the instruction manual. Figure 1-5 A stamping die for a vibration damping tower support partition includes a device body 1, and an upper die 4 is provided on the upper inner side of the device body 1.

[0031] Demolding component 5 is disposed on the side of the upper mold 4;

[0032] The shock absorber tower support is located on the inner side above the wheel arches on both sides of the front compartment (engine compartment) of the vehicle, and is connected to the end of the front longitudinal beam and the bottom area of ​​the A-pillar. It is a key load-bearing component of the vehicle body structure. Its core function is to provide a high-strength mounting base for the top of the shock absorber of the front suspension system and to efficiently distribute the complex dynamic load transmitted by the wheel to the main frame of the vehicle body, such as the front longitudinal beam, front bulkhead and A-pillar. This ensures the geometric accuracy of the suspension, suppresses vibration and abnormal noise, and improves the local stiffness of the body. At the same time, it reduces the risk of fatigue fracture by optimizing the force transmission path, which directly affects the vehicle's handling stability, ride comfort and collision safety.

[0033] The shock absorber tower support is located at the bottom or base of the shock absorber tower structure. It is the main load-bearing and mounting base. It is directly or through connecting plates welded or bolted to the main body structural components such as the front longitudinal beam, front bulkhead, and wheel arch inner panel. Its core function is to bear and transmit the huge load from the top of the front suspension shock absorber to the main body structure.

[0034] The diaphragm is located inside or on the side of the vibration damping tower structure. It is usually welded to the support to form a closed or semi-closed box structure. It mainly plays the role of strengthening, stabilizing and isolating, increasing the overall stiffness and strength of the vibration damping tower, resisting deformation, and preventing the support from twisting or buckling when under stress.

[0035] When manufacturing the baffles inside the vibration damping tower support, the equipment body 1 is required to perform a stamping process to ensure that it forms a specific shape and form.

[0036] Automotive parts stamping equipment mainly consists of a press body, a power system, and a mold system. Its working principle is: the power system controls the upper mold 4 of the mold system to move down and impact the workpiece on the lower mold 2 with rated pressure, so that the workpiece can be formed into a specific shape through the mold system.

[0037] In some embodiments, such as Figure 2 , Figure 4 and Figure 5 As shown, in one embodiment of this utility model, the demolding assembly 5 includes an extrusion rod 503 disposed on the side of the upper mold 4, and a spring 507 is disposed on the opposite side of the two extrusion rods 503.

[0038] When the equipment body 1 needs to press the partition, the driver 3 first turns on and drives the upper mold 4 to press down. When the upper mold 4 moves toward the partition, the lower end of the extrusion rod 503 first contacts the two sides above the partition and is located at the edge. As the upper mold 4 presses down, the two extrusion rods 503 will gradually expand and the spring 507 will be stretched. After the upper mold 4 contacts the partition and presses it, the upper mold 4 no longer contacts the partition and is driven upward by the driver 3. At this time, the two extrusion rods 503 will retract on the surface of the partition as the upper mold 4 rises. At the same time, when the spring 507 resets, it will drive the two extrusion rods 503 to press downward. This can press the pressed partition, thereby preventing the upper mold 4 from lifting the partition after pressing and causing the partition position to shift.

[0039] In this embodiment of the utility model, the demolding assembly 5 further includes a connecting seat 501 fixed to the side of the upper mold 4 by bolts, a movable shell 502 fixedly connected to the surface of the connecting seat 501, and the upper end of the extrusion rod 503 is movably connected to the movable shell 502 through a rotating shaft.

[0040] Connector 501 serves as the main connection structure in demolding assembly 5 that connects to the equipment body 1, such as... Figure 4 As shown, mounting holes are provided at the four corners of its surface. During installation, the personnel need to first measure the width of the lower mold 2, then select the center position, place the connecting seat 501 in the middle of the side of the upper mold 4, and install the demolding assembly 5 as a whole on the side of the upper mold 4 by bolts and mounting holes, thus completing the fixing of the demolding assembly 5.

[0041] In this embodiment of the utility model, the lower end of the extrusion rod 503 is movably connected to an auxiliary wheel 504 via a rotating shaft, and the auxiliary wheel 504 is made of rubber.

[0042] The auxiliary wheel 504, as the first part to contact the partition, is made of rubber. Its contact with the partition surface not only generates a certain friction to achieve an anti-slip effect, but also helps the lower end of the extrusion rod 503 to move smoothly.

[0043] In some embodiments, such as Figure 2 , Figure 4 and Figure 5 As shown, in one embodiment of this utility model, a threaded sleeve is provided inside the movable shell 502, and a lead screw is connected to the inside of the threaded sleeve. The lower end of the lead screw is movably connected to a support rod 505 through a movable seat. The lower end of the support rod 505 is movably connected to a telescopic rod 506 through a rotating shaft. A spring 507 is located on the surface of the telescopic rod 506.

[0044] When encountering different partitions, if the partition is thick, the operator only needs to turn the threaded sleeve to raise the screw. At this time, the two support rods 505 at the lower end of the screw will stretch the spring 507. Thus, when the subsequent pressing rod 503 contacts the partition and expands outward, the force of the previously tensioned spring 507 can be used to further press the partition, thereby increasing the pressing force on the partition.

[0045] Similarly, when a thinner partition is needed, simply drive the lead screw downwards, and the support rod 505 will reset or compress the spring 507. The spring 507 will be in a contracted state, reducing the tension of the spring 507 on the compression rod 503, thus maintaining sufficient downward pressure on the compression rod 503 and preventing the partition from being pulled upwards.

[0046] In this embodiment of the utility model, a rotating shell is fixedly connected between the other end of the telescopic rod 506 and the spring 507, and the end of the rotating shell near the extrusion rod 503 is movably connected to the extrusion rod 503 through a rotating shaft;

[0047] In this embodiment of the utility model, the surface of the movable shell 502 is provided with a through opening, and the threaded sleeve is located in the through opening. The upper and lower parts of the threaded sleeve are fixedly connected to the inner wall of the through opening through bearings.

[0048] In this embodiment of the utility model, a driver 3 is provided above the device body 1, and the output end of the driver 3 is fixedly connected to the upper mold 4. A lower mold 2, which is on the same axis as the upper mold 4, is provided on the lower inner side of the device body 1.

[0049] In this embodiment of the invention, a stamping head is provided inside the upper mold 4;

[0050] The above embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit it. Although this utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features. Such modifications or substitutions will not cause the essence of the corresponding technical solutions to deviate from the spirit and scope of the technical solutions of the embodiments of this utility model.
