The upper stamping die 13 and the lower stamping die 14 are arranged opposite to each other up and down. During stamping processing, a blank 90 is placed in the lower stamping die 14, and the upper machine platform 11 drives the upper stamping die 13 to move downward. The upper stamping die 13 and the lower stamping die 14 squeeze each other to stamp the blank 90; the models of the upper stamping die 13 and the lower stamping die 14 match the model of the blank 90. ​​When processing automobile retaining frames of different models, it is only necessary to replace the upper stamping die 13 and the lower stamping die 14 of the corresponding model to process the blank 90 of the corresponding model.

[0036] The left and right direction of the lower machine 12 is the X direction, the front and rear direction of the lower machine 12 is the Y direction, and the vertical direction is the Z direction; the loading mechanism 20 and the feeding mechanism 40 are respectively arranged on the front and rear sides of the lower machine 12, and the receiving mechanism 80 is connected to the feeding mechanism 40; the area where the loading mechanism 20 is located belongs to the loading area, the area where the feeding mechanism 40 is located belongs to the feeding area, and the area where the upper stamping die 13 and the lower stamping die 14 are located belongs to the processing area; during operation, the loading mechanism 20 pushes the blank 90 to the feeding area, and the feeding mechanism 40 transports the blank 90 to the processing area for stamping, and the stamped finished product 91 after stamping is transported to the receiving hopper 82 through the receiving mechanism 80. The present invention transforms manual operation into automatic operation, and there is no need for the operator to manually feed or collect materials, thus avoiding the risk of accidents that may cause operators; the automatic stamping device has a simple structure, high versatility, good action connection and coherence, stable and reliable operation, low manufacturing and maintenance costs, and can be used in conjunction with the punch press 10 to effectively save labor costs and improve production efficiency.

[0037] Please refer to Figure 1 and Figure 4The feeding mechanism 20 is arranged at the front left end of the lower machine 12. The feeding mechanism 20 includes a feeding sleeve 21, a feeding sleeve fixing frame 22 and a pushing assembly 30. The feeding sleeve fixing frame 22 is fixed at the front left end of the lower machine 12. The feeding sleeve 21 is fixed on the feeding sleeve fixing frame 22 along the Z direction. The upper end of the feeding sleeve 21 is a feeding port. The inner diameter of the feeding port gradually decreases from top to bottom, and the inner diameter of the bottom end of the feeding port is equal to the inner diameter of the feeding sleeve 21, so that the blank 90 can be easily fed into the feeding sleeve 21. The pushing assembly 30 is arranged on the lower machine 12, and the pushing assembly 30 is located below the feeding sleeve 21. The feeding sleeve 21 is arranged vertically, which can ensure that the blank 90 fed is kept vertical, reduce the probability of poor parallelism of the stamped finished product 91, improve the consistency of the stamped finished product 91, improve the yield rate, reduce the waste of raw materials, and save production costs. The blank 90 slides down from the feed sleeve 21 , falls onto the push assembly 30 , and is pushed to the feeding mechanism 40 by the push assembly 30 .

[0038] Preferably, please refer to Figure 1 and Figure 4 The pushing assembly 30 includes a loading fixed plate 31, a first cylinder 32, a first cylinder fixing frame 33, a first slide rail 34, a first slider 35, a pushing plate 36 and a pushing block 37.

Furthermore, the push block 37 is arranged in the middle of the push plate 36, and a blank drop zone is arranged at one end of the push plate 36 which is not connected to the piston rod of the first cylinder 32, and the blank drop zone is located below the feed sleeve 21. In the initial state, the blank drop zone is located directly below the feed sleeve 21. During operation, the blank 90 slides down from the feed sleeve 21 and falls to the blank drop zone on the push plate 36, and the piston rod of the first cylinder 32 extends. Since the push plate 36 is fixedly connected to the piston rod of the first cylinder 32, the push plate 36 is fixedly connected to the first slider 35, and the first slider 35 can move in the Y direction along the first slide rail 34, the piston rod of the first cylinder 32 can drive the push plate 36 and the push block 37 to push the blank 90 to the feeding area along the Y direction.

[0039] Along the Z direction, the distance between the feed sleeve 21 and the push plate 36 is the height of a blank 90, and the height of the push block 37 is equal to the height of a blank 90; along the Y direction, the length of the push block 37 is greater than the outer diameter of a blank 90, which can ensure that the push assembly 30 pushes only one blank 90 to the feeding mechanism 40 at a time, avoids program confusion, and ensures that the automatic stamping device runs smoothly. The inner diameter of the feed sleeve 21 matches the outer diameter of the blank 90, which can prevent the large outer diameter blank from mixing with the small outer diameter blank, and play a role in preventing mixing; processing different models of automobile retainers only requires replacing the feed sleeve 21 with different inner diameters.

Since the feeding air clamp 70 is arranged at the left end of the horizontal plate 632 and the receiving air clamp 81 is arranged at the right end of the horizontal plate 632, when the third cylinder 61 is working, the feeding air clamp 70 and the receiving air clamp 81 can be synchronously moved to the left or right, so as to realize the functions of feeding and receiving materials simultaneously by using a set of driving devices.

[0044] Preferably, a buffer 57 is provided at the lower part of the transmission plate 542 corresponding to the two ends of the third slide rail 64, which plays a role in reducing vibration and noise, avoiding excessive vibration or noise when the third slider 65 slides to the two ends of the third slide rail 64, and ensuring the stable operation of the automatic punching device. In an automatic punching device for an automobile retainer in Example 1 of the present invention, the buffer 57 adopts an AC1410 automatic compensation buffer 57, which operates stably and reliably, but the present invention is not limited thereto.

[0050] Secondly, in the process that the left-right moving assembly 60 drives the feeding air clamp 70 to move leftward, the upper machine table 11 drives the upper stamping die 13 to move downward to perform stamping processing on the Xth blank 90. ​​After the stamping is completed, the upper machine table 11 drives the upper stamping die 13 to move upward to the initial position;

[0051] Thirdly, the feeding air clamp 70 and the receiving air clamp 81 move up and down or left and right together. When the feeding air clamp 70 transports the Xth blank 90 to the lower stamping die 14, the receiving air clamp 81 clamps the X-1th stamping product 91 and transports it to the receiving hopper 82; when the feeding air clamp 70 returns to the initial state to clamp the X+1th blank 90, the receiving air clamp 81 arrives at the lower stamping die 14 and clamps the corresponding Xth stamping product 91; when the feeding mechanism 40 transports the X+1th blank 90 to the lower stamping die 14, the receiving air clamp 81 clamps the Xth stamping product 91 and transports it to the receiving hopper 82.

[0052] By repeating the above process, the automatic stamping function can be realized, and there is no need for the operator to manually feed and collect materials, which reduces labor costs, avoids the risk of accidents that may cause operators, improves production efficiency, and improves the yield rate of products; feeding and collecting materials use the same set of drive transmission devices (up and down moving components 50 and left and right moving components 60), which can improve production efficiency and save production costs.

[0053] In summary, the present invention provides an automatic stamping device for automobile retaining frames, which converts manual operation into automatic operation; the automatic stamping device has a simple structure, high versatility, good action connection and coherence, stable and reliable operation, low manufacturing and maintenance costs, and can be used in conjunction with a punch press to effectively save labor costs and improve production efficiency; the feed sleeve is vertically arranged, and the blank is fed from the feed sleeve, which can prevent mixing of materials and the occurrence of safety accidents, and can also ensure that the blank remains vertical, maintain the consistency of blank processing, reduce the probability of poor parallelism of stamped finished products, improve the yield of stamped products, reduce raw material waste, and improve the quality of stamped products; the blank falls from the feed sleeve onto the push plate, and the push assembly pushes the blank to the feeding area, and the feeding The air clamp clamps the blank, the up and down moving assembly assists the blank to move up and down, and the left and right moving assembly assists the blank to move left and right, and the blank is moved to the lower stamping die. After the feeding air clamp is released, the punch press stamps the blank. The operation is simple, the action connection is good, and the operation is stable and reliable; the feeding air clamp is arranged at the left end of the horizontal plate, and the receiving air clamp is arranged at the right end of the horizontal plate, and the distance between the push plate and the lower stamping die is equal to the distance between the lower stamping die and the higher end of the receiving hopper. During the operation, the feeding air clamp and the receiving air clamp can move synchronously, and the blank is fed and the stamped finished product is received at the same time, which can improve the production efficiency; the feeding and receiving use the same set of driving transmission devices (up and down moving assembly and left and right moving assembly), which can save production costs.
