[0002] In the automotive manufacturing industry, the car center tunnel body is an important structural component of the vehicle body. Its manufacturing precision and forming quality are crucial to the performance of the entire vehicle. Stamping is the main process for producing the car center tunnel body. Traditional stamping dies for the car center tunnel body usually include an upper die and a lower die. The upper die is driven by a press to press down and cooperate with the lower die, causing the metal sheet placed in the die to undergo plastic deformation, thereby obtaining the workpiece of the required shape. After the stamping action is completed, the formed workpiece will remain in the cavity of the lower die.

[0003] In existing technologies, removing the formed workpiece from the lower die usually requires manual operation. Due to the large size and irregular shape of the internal tunnel of an automobile, manual removal is not only labor-intensive but also seriously affects the production cycle and reduces overall production efficiency. At the same time, the operator's hands reaching into the working area of ​​the die to remove the workpiece pose a great safety hazard. In addition, in the feeding stage before stamping, the metal sheet to be processed is large in size, and the operator lacks effective support and guiding devices when feeding it into the die. This makes it difficult to accurately position the sheet, affecting the stamping yield and increasing the complexity and time cost of the operation.

[0004] Therefore, this utility model proposes a stamping die for the automotive center tunnel body to overcome the shortcomings of the prior art. Utility Model Content

Obviously, the described embodiments are only a part of the embodiments of this utility model, and not all of them. 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.

[0026] Example:

[0027] Please refer to Figures 1 to 4 This utility model provides a stamping die for the automotive center channel body, which aims to solve the problems in the prior art where the removal of the automotive center channel body after stamping depends on manual labor, has a low degree of automation, and is inconvenient to operate due to the lack of effective support and positioning during the feeding process.

[0028] like Figure 1 and Figure 2As shown, a stamping die for an automotive tunnel body includes a base 1 and a stamping block 4 disposed above the base 1. The base 1 serves as the mounting base for the entire die, supporting the various functional components of the die. The stamping block 4 is connected to an external hydraulic device and moves downward during the stamping process to cooperate with the base 1, stamping the sheet metal placed on the base 1. Multiple lifting legs 5 are connected between the base 1 and the stamping block 4. Specifically, the lower ends of the multiple lifting legs 5 are fixedly connected to the top of the base 1, and the upper ends of the multiple lifting legs 5 are fixedly connected to the same stamping block 4. The multiple lifting legs 5 provide precise vertical guidance during the pressing and lifting of the stamping block 4, ensuring the stability and positioning accuracy of the stamping process. To achieve automatic ejection of the workpiece after stamping and auxiliary support for the loading process, the die also includes a die ejection mechanism 2 and a support mechanism 3. The die ejection mechanism 2 is disposed inside the base 1. The support mechanism 3 is used to eject the formed model 6 from the base 1 after the stamping operation is completed. The support mechanism 3 is fixed to the outer wall of the base 1 and is used to support and position the sheet metal to be processed before the stamping operation begins. The support mechanism 3 includes two support frames 301 fixedly connected to the right side of the outer wall of the base 1. The support frames 301 provide a stable installation base for the placement frame 304. The same placement frame 304 is mounted on the top of the two support frames 301. The placement frame 304 is used to directly support the sheet metal to be processed. The top of the two support frames 301 is provided with sliding grooves 302. The bottom of the placement frame 304 is fixedly connected to two moving blocks 303. The two moving blocks 303 are slidably connected to the inner wall of the two sliding grooves 302 respectively. By sliding the moving blocks 303 in the sliding grooves 302, the position of the placement frame 304 relative to the base 1 can be adjusted to meet the feeding requirements of sheet metal of different sizes.

[0029] Please refer to Figure 2 and Figure 3The ejection mechanism 2 includes two pneumatic push rods 201 disposed at the bottom of the inner wall of the base 1. The two pneumatic push rods 201 are symmetrically disposed at the bottom of the inner wall of the base 1. The moving end of the pneumatic push rod 201, i.e., the top of the pneumatic push rod 201, is fixedly connected to an inclined slide rail 202. The inclined slide rail 202 moves vertically and vertically in sync with the extension and retraction of the pneumatic push rod 201. An inclined slider 203 is slidably connected to the inner wall of the inclined slide rail 202. The inclined slider 203 can move within the space defined by the inclined slide rail 202. The base 1 slides along an inclined path, and the inner wall of the base 1 is fixedly connected to both ends of a rotating shaft 205. The middle parts of the two adjusting rods 204 are sleeved on the same rotating shaft 205, so that both adjusting rods 204 can rotate around the rotating shaft 205 as a fulcrum. The bottom of each adjusting rod 204 is rotatably connected to the outer wall of the inclined slider 203. When the pneumatic push rod 201 drives the inclined slide rail 202 to rise, the inclined slider 203, constrained by the inner wall of the inclined slide rail 202, will push the bottom of the adjusting rod 204. The top of the adjusting rod 204 moves towards the center, causing it to rotate around the pivot 205. Simultaneously, a sliding block 206 is rotatably connected to the top of the adjusting rod 204. The sliding block 206 is slidably connected to the inner wall of the sliding rail 207, and a top plate 208 is fixedly connected to the top of the sliding rail 207. This structure allows the upward force to be transmitted to the sliding rail 207 and the top plate through the sliding engagement of the sliding block 206 and the sliding rail 207 when the top of the adjusting rod 204 moves towards the center due to rotation. 208, thereby driving the top plate 208 to rise and fall steadily. Finally, the top of the top plate 208 is used to eject the stamped mold 6. This lever-slider transmission mechanism, driven by the pneumatic push rod 201 and consisting of the inclined slide rail 202, the inclined slider 203, the adjusting rod 204, and the sliding block 206 and the sliding rail 207, ensures that the linear motion of the pneumatic push rod 201 can be smoothly and effectively converted into the vertical ejection motion of the top plate 208, thus realizing the automation of the mold ejection action.

[0030] In a preferred embodiment, in order for the pneumatic push rod 201 to accurately drive the inclined slide rail 202, the top of the pneumatic push rod 201 is fixedly connected to the inclined slide rail 202 by welding or bolts, while the inclined slider 203 has good guidance and stability when sliding on the inner wall of the inclined slide rail 202.

[0031] As another preferred embodiment, in order to ensure that the adjusting rod 204 can smoothly drive the top plate 208 to rise and fall when rotating, the top of the adjusting rod 204 is rotatably connected to the sliding block 206 through a pin. The sliding block 206 and the inner wall of the sliding rail 207 are in clearance fit to ensure smooth sliding. The top of the sliding rail 207 is fixedly connected to the bottom of the top plate 208 by multiple bolts. The top of the top plate 208 is flat and is used to directly and evenly contact the bottom of the stamped mold 6.

[0032] In another preferred embodiment, in order to ensure the synchronicity and stability of the transmission mechanisms on both sides of the ejection mechanism 2, the two symmetrically arranged pneumatic push rods 201 are controlled by the same controller to ensure that the two pneumatic push rods 201 extend and retract synchronously. The two adjusting rods 204 are linked through the same rotating shaft 205. The two ends of the rotating shaft 205 are fixed to the inner wall of the base 1 through bearing seats, thereby ensuring that the swing angle and speed of the two adjusting rods 204 are consistent.

[0033] In a preferred embodiment, to make the structure of the support mechanism 3 more stable, the two support frames 301 are fixedly connected to the right side of the outer wall of the base 1 by bolts, and the connection between the support frame 301 and the base 1 can be provided with reinforcing ribs. The top of the two support frames 301 is supported by the same placement frame 304 to provide a continuous and flat bearing surface.

[0034] As another preferred embodiment, in order to make the adjustment process of the placement rack 304 smoother and more reliably locked, the cross-sectional shape of the moving block 303 and the sliding groove 302 can be T-shaped or dovetail-shaped to prevent the moving block 303 from coming out of the sliding groove 302, and locking bolts can be provided on the side wall of the sliding groove 302 to lock and fix the moving block 303 after it is adjusted to a suitable position.

[0035] In another preferred embodiment, in order to ensure the rigidity and guiding accuracy of the stamping process, the lower ends of the multiple lifting legs 5 are fixedly connected to the top plane of the base 1 by flanges and bolts, and the upper ends of the multiple lifting legs 5 are also fixedly connected to the bottom of the stamping block 4 by flanges and bolts. The lifting legs 5 are preferably high-strength guide columns.

[0036] Working principle: Before the stamping operation, the metal sheet to be processed is placed on the placement frame 304 of the support mechanism 3. Since the two moving blocks 303 fixedly connected to the bottom of the placement frame 304 are slidably connected to the inner walls of the two sliding grooves 302 at the top of the two support frames 301, the operator can adjust the position of the placement frame 304 by sliding the moving blocks 303 to adapt to the sheet of different lengths. After adjustment, the sheet is smoothly pushed from the right side to the left side of the placement frame 304 into the top processing area of ​​the base 1. Through the bearing and limiting of the placement frame 304, the feeding process is more labor-saving and safer, and the risk of direct contact between the operator and the stamping block 4 is reduced. When the stamping operation is performed, the external hydraulic equipment fixedly installed with the stamping block 4 is started, driving the stamping block 4 to move downward under the precise guidance of multiple lifting legs 5, and cooperate with the base 1 to close the mold, stamp the metal sheet, and form it into the preset model 6.

[0037] After stamping, the ejection mechanism 2 is activated, and two pneumatic push rods 201 installed on the bottom of the inner wall of the base 1 extend synchronously. The top of each pneumatic push rod 201 is fixedly connected to an inclined slide rail 202. Therefore, the rise of the pneumatic push rod 201 causes the inclined slide rail 202 to rise vertically synchronously. Since the inclined slider 203 is slidably connected to the inner wall of the inclined slide rail 202, and the outer wall of the inclined slider 203 is rotatably connected to the bottom of the adjusting rod 204, the inclined slider 203 slides within the inclined track of the inclined slide rail 202 during the rise of the inclined slide rail 202. This sliding generates a horizontal component force, pushing the bottoms of the two adjusting rods 204 synchronously towards the center. Since the inner walls of the two adjusting rods 204 are rotatably connected to the same fixed rotating shaft 205, the contraction movement of the bottom of the adjusting rods 204 will revolve around the rotating shaft. Rotate 205, bringing the top of the adjusting rod 204 towards the center and generating an upward force. Since the top of the adjusting rod 204 is rotatably connected to the sliding block 206, and the sliding block 206 is slidably connected to the inner wall of the sliding rail 207, when the adjusting rod 204 rotates and pushes upward, it will drive the sliding block 206 to slide on the inner wall of the sliding rail 207. The upward force generated when the top of the adjusting rod 204 retracts towards the center will push the sliding rail 207 upward and move it. Since the top of the sliding rail 207 is fixedly connected to the top plate 208, and the top of the top plate 208 is in contact with the bottom of the model 6, the sliding rail 207 is finally lifted by the retraction movement of the adjusting rod 204, which drives the top plate 208 to rise and continue to rise, smoothly pushing the model 6 out of the base 1 for easy handling by the operator, thus realizing the automatic demolding of the stamped workpiece.
