Description

Technical Field

[0001] The present invention belongs to the technical field of automobile hinge stamping equipment, and particularly relates to a stamping mechanism for automobile hinges. Background Art

[0002] In the prior art, an automobile hinge is a key component connecting a car door and a vehicle body, which can enable the car door to be opened and closed smoothly and ensure that the car door remains fixed during driving. The design of the hinge not only needs to consider durability and reliability, but also takes into account requirements of safety, comfort and aesthetics. Generally, during the production process, it is often necessary to stamp the hinge to obtain a reserved hole for articulation.

[0003] The prior art discloses a stamping mechanism for automobile hinges, including a mounting plate, a mounting door, a sliding block, a clamping door, a transverse movement bolt, a threaded groove, a blanking hole, a blanking pipe, a blanking piston, a connecting rod and an adjusting screw. In this mechanism, the mounting plate is installed at the working position, the hinge is placed on the mounting plate, and by screwing the adjusting screw, the sliding block is driven to slide down on the mounting door, and then the clamping door is driven to clamp the hinge. When it is necessary to clamp hinges of different sizes, the transverse movement bolt is screwed, and under the action of the threaded groove, the transverse movement bolt drives the clamping door to move transversely, thereby adjusting the clamping distance. When clamping and stamping are completed, the waste material falls onto the blanking piston on the blanking pipe through the blanking hole. By pulling the connecting rod to move downward and disengaging from the blanking pipe, the waste material is driven to fall, and the rapidly descending blanking piston generates a downward airflow, so that debris is sucked in through the blanking hole.

[0004] The above prior art can drive the sliding block to slide down on the mounting door by screwing the adjusting screw, and then drive the clamping door to clamp the hinge to improve the stability of stamping. However, in actual use, generally, the material is fixed first and then stamped, and then the stamped material is disassembled after stamping. However, during the lower-side stamping, the operation process requires frequent disassembly by personnel, consuming manpower. At the same time, during the stamping process, personnel can only wait and cannot make full use of time, directly affecting the processing efficiency. Summary of the Invention

Detailed implementation manners

[0031] The present invention will be further described below in conjunction with the embodiments:

[0032] The present invention will be further described in detail below in conjunction with the drawings and embodiments. It can be understood that the specific embodiments described herein are only used to explain the present invention and are not intended to limit the present invention. Additionally, it should be noted that for the sake of convenience of description, only the parts related to the present invention rather than all the structures are shown in the drawings.

[0033] It should be noted that: similar reference numerals and letters represent similar items in the following drawings. Therefore, once an item is defined in one drawing, it does not need to be further defined and explained in subsequent drawings. At the same time, in the description of the present invention, terms such as "first", "second", etc. are only used for distinguishing descriptions and cannot be understood as indicating or implying relative importance.

[0034] The stamping mechanism for automotive hinges of the present invention can be applied to the hinge project on the Volkswagen site, including a load-bearing plate 1. A drive groove 2 is opened on the upper side of the load-bearing plate 1. A reversing motor 3 is fixedly connected to the inner wall of the drive groove 2. The output end of the reversing motor 3 is fixedly connected to a limit die 4. Two limit grooves 5 are opened on the upper side of the limit die 4. The limit grooves 5 are used to place the original hinge plates for limiting. A support ring 6 that cooperates with the lower side of the limit die 4 is fixedly connected to the upper side of the load-bearing plate 1.

[0035] Specifically, the reversing motor 3 and the drive groove 2 can be connected by a common fixing method.

[0036] A drop port 7 is opened on the upper side of the support ring 6. The waste after stamping drops from the drop port 7 into a waste bin 13. Discharge ports 8 are opened on both the support ring 6 and the load-bearing plate 1.

[0037] In order to collect the processed materials for subsequent processing, a receiving assembly 9 that cooperates with the discharge port 8 is arranged on the lower side of the load-bearing plate 1. The receiving assembly 9 includes two convex grooves 901 opened on one side of the load-bearing plate 1, limit blocks 902 slidably fitted on the inner walls of the convex grooves 901, and a receiving box 903 fixedly connected to the lower sides of the two limit blocks 902. When the limit blocks 902 are inserted into the convex grooves 901, the receiving box 903 can be moved, so that the receiving box 903 moves to the lower side of the discharge port 8 to receive and store the materials flowing through the discharge port 8.

[0038] On the upper side of the load-bearing plate 1, a stamping assembly 10 that cooperates with the dropping port 7 is fixedly connected, and a pressing assembly 11 is arranged on the upper side of the limiting die 4.

The stamping cutter 103 is pressed downward by the hydraulic cylinder 102 to perform stamping operations on materials. In order to press down the materials in the limiting groove 5, when the limiting groove 5 moves to the discharge port 8, its fixed pressure can cause the materials to separate from the limiting groove 5. The pressing assembly 11 includes an empty groove plate 111 fixedly connected to the upper side of the limiting die 4, a movable block 112 slidably fitted to the inner wall of the empty groove plate 111, a spring 113 fixedly connected between the movable block 112 and the empty groove plate 111, and a pressing column 114 fixedly connected to the lower side of the movable block 112 for pressing downward. After the materials are placed into the limiting groove 5, the spring 113 on the upper side of the movable block 112 presses it, so that the pressing column 114 maintains a downward force to limit the materials in the limiting groove 5, and when squeezing, the limiting groove 5 can limit the squeezed materials.

[0043] Embodiment 1

[0044] As Figures 1 - 5As shown in the figure, a stamping mechanism for an automobile hinge includes a load-bearing plate 1. A driving groove 2 is formed on the upper side of the load-bearing plate 1. A turning motor 3 is fixedly connected to the inner wall of the driving groove 2. The output end of the turning motor 3 is fixedly connected with a limiting die 4. The turning motor 3 and the limiting die 4 can be fixed by bolts, and different limiting dies 4 can be replaced to improve the scope of application. Two limiting grooves 5 are formed on the upper side of the limiting die 4. The upper side of the load-bearing plate 1 is fixedly (the fixing method is not unique) connected with a support ring 6 that cooperates with the lower side of the limiting die 4.

[0045] A dropping port 7 is formed on the upper side of the support ring 6. Discharge ports 8 are formed on both the support ring 6 and the load-bearing plate 1. A receiving assembly 9 that cooperates with the discharge port 8 is arranged on the lower side of the load-bearing plate 1. A stamping assembly 10 that cooperates with the dropping port 7 is fixedly connected to the upper side of the load-bearing plate 1. A pressing assembly 11 is arranged on the upper side of the limiting die 4.

[0046] The receiving assembly 9 includes two convex grooves 901 formed on one side of the load-bearing plate 1, limiting blocks 902 slidably fitted to the inner walls of the convex grooves 901, and a receiving box 903 fixedly connected to the lower sides of the two limiting blocks 902. Inserting the limiting blocks 902 into the convex grooves 901 can move the receiving box 903, so that the receiving box 903 moves to the lower side of the discharge port 8 to receive and store the materials flowing through the discharge port 8. Specifically, the limiting blocks 902 are inserted into the inner cavities of the convex grooves 901, and the movement of the limiting blocks 902 in the inner cavities of the convex grooves 901 drives the receiving box 903 to move.

[0047] The stamping assembly 10 includes a gantry 101 fixedly connected to the upper side of the load-bearing plate 1, a hydraulic cylinder 102 fixedly connected to the gantry 101, and a stamping tool 103 fixedly connected to the output end of the hydraulic cylinder 102. The stamping operation on the materials is realized by the hydraulic cylinder 102 squeezing the stamping tool 103 downward.

[0048] The pressing assembly 11 includes an empty groove plate 111 fixedly connected to the upper side of the limiting die 4, a movable block 112 slidably fitted to the inner wall of the empty groove plate 111, a spring 113 fixedly connected between the movable block 112 and the empty groove plate 111, and a pressing column 114 fixedly connected to the lower side of the movable block 112. After the materials are placed in the limiting grooves 5, the spring 113 on the upper side of the movable block 112 squeezes it, so that the pressing column 114 maintains a downward force to limit the materials in the limiting grooves 5. When being squeezed, the limiting grooves 5 can limit the squeezed materials.

[0049] A storage groove 12 is formed on the other side of the load-bearing plate 1. A waste material box 13 is fixedly connected to the inner wall of the storage groove 12. By placing the waste material box 13 into the storage groove 12, the waste materials flowing out from the dropping port 7 after processing can be uniformly collected, increasing the convenience of subsequent processing.

[0050] A plurality of support legs 14 are fixedly connected to the lower side of the load-bearing plate 1, and a buffer pad 15 is fixedly connected to the lower sides of the plurality of support legs 14. The support legs 14 facilitate the support of the load-bearing plate 1, and the buffer pad 15 can absorb the sound generated during the operation of the load-bearing plate 1.

[0051] An electric telescopic rod 16 is fixedly connected to the upper side of the load-bearing plate 1. The output end of the electric telescopic rod 16 is fixedly connected to a clamping block 17. Reserved openings 18 that match the clamping block 17 are formed on both sides of the limiting die 4. After the limiting die 4 is flipped, by inserting the clamping block 17 on the electric telescopic rod 16 into the reserved openings 18, it can be indicated that there is no deviation. If the clamping block 17 cannot be inserted into the reserved openings 18, it means that the position of the limiting die 4 is incorrect, avoiding affecting the processing efficiency.

[0052] An observation port 19 is formed on the front side of the receiving box 903, and a transparent plate 20 is fixedly connected inside the observation port 19. By looking through the transparent plate 20 in the observation port 19, it is convenient to observe the storage level of the receiving box 903.

[0053] Working principle:

[0054] During use, first, the electric telescopic rod 16 is contracted to drive the clamping block 17 to move downward and separate from the reserved opening 18. The hinge material that matches the limiting groove 5 is placed inside the inner limiting groove 5. Under the action of the spring 113 pressing against the movable block 112, the extrusion column 114 and the hinge material placed inside the limiting groove 5 are pressed downward to limit the material. By starting the flipping motor 3 to drive the limiting die 4 to rotate 180 degrees, the two limiting grooves 5 are swapped in position. The originally installed hinge is sent below the stamping tool 103. By starting the hydraulic cylinder 102 on the gantry 101 to drive the stamping tool 103 to stamp the material in the limiting groove 5, the waste after stamping falls from the dropping port 7 into the waste bin 13. During the stamping process, materials can be pre-placed in the other limiting groove 5. When the stamping is completed, the two limiting grooves 5 can be directly swapped, realizing pre-placement of materials during the processing process, improving the utilization rate of time, and thus improving the processing efficiency;

[0055] After the processing is completed, during the process of rotating the limiting die 4, when the limiting groove 5 carrying the processed material moves to the upper side of the discharging port 8, due to the spring 113 pressing against the movable block 112, the extrusion column 114 pushes the processed material in the limiting groove 5 into the discharging port 8 and drops into the receiving box 903 for storage, realizing automatic blanking, improving the automation degree of processing, and saving manpower and operation time.

[0056] Note that the above is only the preferred embodiment of the present invention and the technical principles applied. Those skilled in the art will understand that the present invention is not limited to the specific embodiments described herein. Various obvious changes, re-adjustments, and substitutions can be made by those skilled in the art without departing from the protection scope of the present invention.
