[0002] Fine blanking machines are currently widely used in the processing of precision mechanical products and parts with high requirements. The raw materials used are usually divided into two types: coils and slabs. Since the production of medium and thick coils is relatively small, slabs are currently the most common raw materials used for fine blanking of medium and thick aluminum alloys. After the slabs are cut into strips by the shearing machine, they need to be loaded and unloaded frequently during the production process due to their short length. Traditional manual operation has defects such as high labor intensity for workers and the presence of human factors that easily lead to poor installation position of the slabs and the need for adjustment, which seriously reduces the efficiency of the fine blanking machine.

[0039] The telescopic assembly 8 includes a column 801, a fixed seat 802 and a movable seat 803. The column 801 is vertically installed on the workbench 101. The top of the column 801 is installed in a guide hole opened on the movable plate 4. The fixed seat 802 and the movable seat 803 are sleeved on the column 801. The fixed seat 802 and the movable seat 803 are located between the workbench 101 and the movable plate 4. A spring three 807 is installed between the fixed seat 802 and the movable seat 803. The movable plate 4 pushes the movable seat 803 to slide downward along the column 801. Two pin shafts 8031 ​​are provided on one side of the movable seat 803. The two pin shafts 8031 ​​are respectively rotatably installed with a rotating arm 1 804 and a rotating arm 2 805.

[0041] The feeding assembly 9 includes a stand 901, which is fixedly mounted on the workbench 101. A guide plate 902 is fixedly mounted on the inner side of the stand 901, and a sliding plate 903 is slidably mounted on the guide plate 902. Pin rods 904 are provided on the two opposite outer sides of the sliding plate 903, and a rotating arm 805 is sleeved on the pin rod 904. A circular slot is provided at the end of the sliding plate 903. When the distance between the fixed seat 802 and the movable seat 803 is the largest, the circular slot of the sliding plate 903 corresponds to the slot body 7013.

[0042] A material storage box 14 is fixedly installed on the stand 901, and the workpiece 13 to be processed is stored in the material storage box 14. When the distance between the fixed seat 802 and the movable seat 803 is the smallest, the circular slot of the sliding plate 903 is aligned with the discharge hole of the material storage box 14. When the distance between the fixed seat 802 and the movable seat 803 is the largest, the other side of the sliding plate 903 is located below the discharge hole of the material storage box 14.

[0043] A track 11 is fixed to the discharge end of the die base 701 , and discharge assemblies 10 are slidably mounted on opposite sides of the die base 701 .

[0044] The blanking assembly 10 includes a sliding rod 1001, which slides along the side of the mold base 701 and the corresponding track 11.

[0045] When in use, the workpiece 13 to be processed is placed in the material storage box 14. Since the distance between the discharge end of the material storage box 14 and the sliding plate 903 is greater than the thickness of one workpiece 13 to be processed, it is less than the thickness of two workpieces 13 to be processed;

[0046] When the hydraulic lifting column 6 is extended to the maximum extension, the distance between the fixed seat 802 and the movable seat 803 is the smallest, and the corresponding sliding seat 806 is pushed to slide outward first by the rotating arm 805, and the sliding seat 806 drives the sliding plate 903 to slide along the guide plate 902 toward one side of the storage box 14;

[0048] When the circular slot at the end of the sliding plate 903 is aligned with the second slot body 7013, the other end of the sliding plate 903 is located below the discharge hole of the material storage box 14 to prevent the workpiece 13 to be processed from falling between the sliding plate 903 and the stand 901;

[0049] When the hydraulic lifting column 6 is extended to the maximum extension again, the stamping die installed on the bottom surface of the movable plate 4 stamps the workpiece 13 to be processed placed in the second groove body 7013. During the reset of the hydraulic lifting column 6, the distance between the fixed seat 802 and the movable seat 803 gradually increases, and the rotating arm 1 804 drives the sliding rod 1001 connected thereto to approach the processed workpiece 12 until the distance between the fixed seat 802 and the movable seat 803 is the largest. The two elastic rods 1003 clamp the processed workpiece 12, and the feeding assembly 9 repeats the above work;

[0050] When the hydraulic lifting column 6 moves downward, the rotating arm 804 pushes the sliding rod 1001, the elastic rod 1003 and the processed workpiece 12 to move outward, so that the processed workpiece 12 can be taken out and the automatic loading and unloading is realized.
