Description

Technical Field

[0001] The utility model relates to the technical field of stamping dies, in particular to a stamping die for a connecting plate of an automobile accessory. Background Art

[0002] The stamping die of the connecting plate of automobile parts is a special process equipment used to process materials into connecting plate parts of automobile parts in cold stamping. The stamping die, commonly known as the cold stamping die, is a pressure processing method and process equipment that uses a die installed on a press to apply pressure to the material at room temperature to cause it to separate or plastically deform, thereby obtaining the required parts. In the stamping process of the connecting plate of automobile parts, the pressure applied by the die through the press causes the metal sheet to undergo plastic deformation inside the die to form the required connecting plate shape and size. This process usually includes stamping, bending, stretching and other processes of the material, and finally forms an automobile part connecting plate that meets the requirements. The stamping die can ensure the size and shape accuracy of the connecting plate of automobile parts and meet the high standards of automobile manufacturing. Through continuous stamping of the die, production efficiency can be greatly improved and production costs can be reduced. High-quality stamping dies are usually made of high-strength and high-hardness materials, and can withstand long-term and frequent stamping operations without being easily damaged.

[0003] To this end, China's patent application number CN214919962U discloses a stamping die for automobile connecting plates, including a base plate, a top middle end of the base plate is fixedly connected to a processing table, the top of the base plate is located on both sides of the processing table and is fixedly connected to support columns, the top of the support columns is fixedly connected to a top plate, the top of the top plate is fixedly connected to a hydraulic telescopic cylinder, the bottom of the hydraulic telescopic cylinder is fixedly connected to a fixed plate, the bottom of the fixed plate is fixedly connected to a stamping die, and the processing table is fixedly connected to a baffle through a horizontal adjustment mechanism, so that the device can adjust the height of the clamping plate through the clamping mechanism, so that the device can clamp and position automobile connecting plates of different thicknesses, thereby preventing the automobile connecting plates from sliding during stamping processing, thereby greatly improving the processing quality and scope of application of the device, and the device has a simple structure, good clamping effect, and extremely strong practicality.

[0004] Today's stamping dies for connecting plates of automotive parts can basically meet people's needs, but there are still some problems. The specific problems are as follows:

[0005] 1. The stamping die of the connecting plate of automobile parts is difficult to stamp continuously. In the process of the connecting plate of automobile parts, the staff usually needs to manually place the material between the upper and lower dies. After the stamping is completed, the processed connecting plate of automobile parts is removed from the lower die and new material is put in again. The overall operation is complicated, and the staff will come into contact with the stamping die, which is prone to danger.

[0006] 2. The stamping die of the connecting plate of automotive parts is difficult to fix the material. During the stamping process, the material must maintain a stable position and state to ensure the size and shape accuracy of the stamped parts. When the upper die contacts the material, the position of the material may move due to the influence of the position of the force point. The material needs to be fixed to avoid material displacement during the stamping process. Utility Model Content

[0007] The utility model aims to provide a stamping die for a connecting plate of an automobile part, so as to solve the defects of the existing stamping die for the connecting plate of an automobile part, that is, it is difficult to perform continuous stamping and to fix the material.

[0008] In order to solve the above technical problems, the present utility model provides the following technical solutions: a stamping die for a connecting plate of an automobile accessory, comprising a support leg;

[0009] An operating table is fixed on the top of the support leg, a support frame is fixed on the top of the operating table, and a cylinder is installed inside the top of the support frame;

[0010] A first spring is provided on the outer side of the bottom end of the support frame, a limit plate is fixed to the bottom end of the cylinder, and a feeding mechanism is installed on one side of the operating table;

[0011] An upper mold is installed at the bottom end of the limiting plate, a lower mold is installed at the top end of the operating table, fixed structures are installed at both ends of the top end of the operating table, and discharging structures are installed at both ends of the bottom end of the limiting plate.

[0012] When in use, first place the raw material in the feeding trough of the feeding table. The servo motor can drive the feeding wheel to rotate, so as to feed the raw material into the space between the upper mold and the lower mold in sections. The extension of the cylinder can drive the upper mold to move downward. During the descent of the upper mold, the push blocks at both ends squeeze the clamping plate to the middle to fix the position of the raw material. When the upper mold descends, the raw material is first cut with a blade, and then the raw material is stamped. During the rise of the upper mold to its original position, the clamping block returns to its original position under the joint action of the second spring and the support rod. The ejector rod rises with the upper mold to eject the stamped auto parts connecting plate. When the next stamping is performed, the raw material at the next end will push the stamped auto parts connecting plate into the discharge trough, completing the entire stamping process and realizing continuous stamping.

[0013] Furthermore, the feeding mechanism includes a feeding table, a feeding trough, a roller, a servo motor, a first rotating shaft, a driving gear, a driven gear, a second rotating shaft and a feeding wheel. The feeding table is integrally formed on one side of the operating table, and feeding troughs are provided on both sides of the top of the feeding table. A servo motor is installed on the top of the feeding table, and a first rotating shaft is installed on the output end of the servo motor. A driving gear is welded on one side of the first rotating shaft, and a driven gear is meshed and connected on one side of the driving gear. A second rotating shaft is welded on one end of the driven gear, and a feeding wheel is fixed on the outside of the second rotating shaft. Continuous feeding can be achieved without the need for staff operation, so that the stamping die can stamp continuously.

[0014] Furthermore, rollers are rotatably connected inside both ends of the feeding platform, and the rollers are arranged at equal intervals inside the two ends of the feeding platform, which can further assist the raw materials to be pushed to one side.

[0015] Furthermore, one side of the driving gear and one end of the driven gear are both provided with latching teeth, and the driving gear and the driven gear are meshingly connected. When the servo motor is started, the first rotating shaft rotates to drive the driving gear to rotate, and the driving gear rotates to drive the driven gear to rotate, thereby finally driving the feeding wheel to rotate.

[0016] Furthermore, the fixing structure includes a push block, a fixing plate, a support rod, a second spring and a clamping plate. The push block is fixed to the two ends of the bottom end of the limit plate, and the fixing plate is fixed to the two ends of the top end of the operating table. A support rod passes through the inside of the fixing plate, and a second spring is fixed to the outside of one end of the support rod. A clamping plate is fixed to the other end of the support rod, which can clamp and fix the material during the stamping process.

[0017] Furthermore, the discharging structure includes a blade, an ejector rod, a through hole and a discharging trough. The ejector rod is fixed on both sides and both ends of the bottom end of the limit plate. The through hole is opened on both sides and both ends inside the lower mold. The discharging trough is opened on one side of the operating table to facilitate the collection of the stamped automotive parts connecting plates.

[0018] Furthermore, the blades are fixed on both sides of the bottom end of the upper mold, and the blades are symmetrically distributed about the central axis of the upper mold to cut the raw material, which is convenient for subsequent stamping operations.

[0019] The utility model provides a stamping die for a connecting plate of an automobile part, which has the advantages that: by installing a feeding table on one side of an operating table, raw materials can be placed in a feeding trough, and when the servo motor is started, the first rotating shaft rotates to drive the driving gear to rotate, the driving gear rotates to drive the driven gear to rotate, and the driven gear rotates to drive the second rotating shaft and the feeding wheel to rotate, and the second rotating shaft is on one side of the center of the feeding wheel, so that the feeding wheel can keep the raw materials at the same length and intermittently feed them between the upper die and the lower die through the friction between the outer anti-slip ring and the raw materials, and the roller can further assist the raw materials in pushing to one side during the conveying process of the raw materials, thereby realizing continuous feeding without the need for staff operation, allowing the stamping die to stamp continuously, reducing the risk of manual operation, and thereby achieving the purpose of continuous stamping of the stamping die for the connecting plate of automobile parts.

[0020] By fixing push blocks at both ends of the upper die, the limit plate and the upper die are driven downward after the cylinder is extended, and the push block is driven downward at the same time. After falling to the moving height, the push block squeezes the splint to the middle to clamp the raw material, ensuring the stability of the raw material position. In the process of the splint moving to the middle, it drives the support rod to move together. Since the position of the fixed plate remains unchanged, the second spring is stretched. After the stamping is completed, the push block rises with the upper die and the limit plate, and returns to its original shape under the action of the second spring. Under the action of the second spring, it drives the support rod and the splint back to their original position, ending the clamping effect on the raw material, thereby achieving the purpose of the stamping die of the connecting plate of the automotive parts to fix the material.

[0027] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0028] See also Figure 1-Figure 5 The utility model provides an embodiment: a stamping die for a connecting plate of an automobile accessory, comprising a support leg 1.

[0029] An operating platform 2 is fixed to the top of the support leg 1 , a support frame 3 is fixed to the top of the operating platform 2 , and a cylinder 4 is installed inside the top of the support frame 3 .

[0030] A first spring 5 is provided on the outer side of the bottom end of the support frame 3 , and a limit plate 6 is fixed to the bottom end of the cylinder 4 .

[0031] A feeding mechanism 7 is installed on one side of the operating table 2. The feeding mechanism 7 includes a feeding table 701, a feeding trough 702, a roller 703, a servo motor 704, a first rotating shaft 705, a driving gear 706, a driven gear 707, a second rotating shaft 708 and a feeding wheel 709. The feeding table 701 is integrally formed on one side of the operating table 2. Feeding troughs 702 are provided on both sides of the top of the feeding table 701. The interior of both ends of the feeding table 701 is rotatably connected to rollers 703. The rollers 703 are arranged at equal intervals inside the interior of the two ends of the feeding table 701. A servo motor 704 is installed on the top of the feeding table 701, and a first rotating shaft 705 is installed on the output end of the servo motor 704. A driving gear 706 is welded on one side of the first rotating shaft 705, and a driven gear 707 is meshed with one side of the driving gear 706. One side of the driving gear 706 and one end of the driven gear 707 are both provided with locking teeth. The driving gear 706 and the driven gear 707 are meshed. A second rotating shaft 708 is welded on one end of the driven gear 707, and a feeding wheel 709 is fixed on the outside of the second rotating shaft 708.

[0032] As shown in the accompanying drawings, a feeding table 701 is installed on one side of the operating table 2, and the raw materials can be placed in the feeding trough 702. When the servo motor 704 is started, the first rotating shaft 705 rotates to drive the driving gear 706 to rotate, and the driving gear 706 rotates to drive the driven gear 707 to rotate. The driven gear 707 rotates to drive the second rotating shaft 708 and the feeding wheel 709 to rotate. The second rotating shaft 708 is on one side of the center of the feeding wheel 709, so that the feeding wheel 709 can keep the raw materials at the same length intermittently fed between the upper mold 8 and the lower mold 9 through the friction between the outer anti-slip ring and the raw materials. During the transportation of the raw materials, the roller 703 can further assist the raw materials to be pushed to one side, thereby realizing continuous feeding without the need for staff operation, allowing the stamping mold to stamp continuously, reducing the risk of manual operation.

[0033] An upper mold 8 is installed at the bottom end of the limiting plate 6 , and a lower mold 9 is installed at the top end of the operating table 2 .

[0034] A fixed structure 10 is installed at both ends of the top of the operating table 2. The fixed structure 10 includes a push block 1001, a fixed plate 1002, a support rod 1003, a second spring 1004 and a splint 1005. The push block 1001 is fixed to both ends of the bottom end of the limit plate 6, and the fixed plate 1002 is fixed to both ends of the top of the operating table 2. The support rod 1003 runs through the inside of the fixed plate 1002, and the second spring 1004 is fixed to the outside of one end of the support rod 1003, and the splint 1005 is fixed to the other end of the support rod 1003.

[0035] As shown in the accompanying drawings, push blocks 1001 are fixed at both ends of the upper mold 8. After the cylinder 4 is extended, it drives the limit plate 6 and the upper mold 8 to move downward, and at the same time drives the push block 1001 to move downward at the same time. After descending to the moving height, the push block 1001 squeezes the clamping plate 1005 toward the middle to clamp the raw material, ensuring the stability of the raw material position. In the process of the clamping plate 1005 moving toward the middle, it drives the support rod 1003 to move together. Since the position of the fixed plate 1002 remains unchanged, the second spring 1004 is stretched. After the stamping is completed, the push block 1001 rises with the upper mold 8 and the limit plate 6, and then returns to its original shape on the second spring 1004. Under the action of the second spring 1004, it drives the support rod 1003 and the clamping plate 1005 back to their original position, ending the clamping effect on the raw material.

[0036] Both ends of the bottom end of the limiting plate 6 are equipped with a discharge structure 11, and the discharge structure 11 includes a blade 1101, an ejector rod 1102, a through hole 1103 and a discharge trough 1104. The blade 1101 is fixed on both sides of the bottom end of the upper mold 8, and the blade 1101 is symmetrically distributed about the central axis of the upper mold 8. The ejector rod 1102 is fixed on both sides and both ends of the bottom end of the limiting plate 6, the through hole 1103 is opened on both sides and both ends of the lower mold 9, and the discharge trough 1104 is opened on one side of the operating table 2.

[0037] As shown in the accompanying drawings, while the feed wheel 709 rotates to drive the raw material to move, the upper mold 8 moves downward under the drive of the cylinder 4, and at the same time drives the ejector rod 1102 to move downward and hide in the through hole 1103. During the descending process of the upper mold 8, the blade 1101 will first contact the raw material and cut the raw material to facilitate subsequent stamping operations. After the stamping is completed, the ejector rod 1102 rises with the upper mold 8, and finally exceeds the height of the through hole 1103 and ejects the stamped auto parts connecting plate from the lower mold 9. During the next stamping, the ejector rod 1102 drops back into the through hole 1103, and the next section of material fed by the feed wheel 709 will push the processed auto parts connecting plate into the discharge trough 1104, avoiding affecting the next stamping, and also facilitating the collection of the auto parts connecting plate.

[0038] Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments, or make equivalent substitutions for some of the technical features therein. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
