Description

Technical Field

[0001] The present invention relates to the technical field of sheet metal stamping, and particularly to an automatic feeding device for automatic stamping and forming of sheet metal parts. Background Technique

[0002] Sheet metal is a comprehensive cold working process for metal sheets (usually less than 6 mm in thickness), including shearing, punching / cutting / combining, folding, welding, riveting, splicing, forming (such as automobile body), etc. Its remarkable feature is that the thickness of the same part is consistent, and the product processed by sheet metal technology is called a sheet metal part.

[0015] Compared with the prior art, the present invention has the following beneficial effects: 1. For this automatic feeding device for stamping and forming of automatic sheet metal parts, during the stamping work of sheet metal parts, through the automatic feeding structure, driven by the first motor, its output shaft drives the belt pulley to rotate, so that the linkage belt drives the connecting block to move, thereby enabling the connecting block to drive the first sliding rod to slide inside the fixed slide rail, so that the two negative pressure suction cups can move above the stamping table and the stacking table. Subsequently, driven by two electric cylinders, the two telescopic rods drive the negative pressure generator to slide downward inside the mounting plate, so that the negative pressure suction cup above the stacking table contacts the sheet metal part, and the negative pressure suction cup above the stamping table contacts the stamped sheet metal part. Driven by the negative pressure generator, the sheet metal part is adsorbed. Subsequently, driven by the first motor again, the two negative pressure suction cups are moved above the stamping table and the blanking table, so as to place the unstamped sheet metal part above the stamping table and place the stamped sheet metal part above the blanking table, thus achieving the purpose of automatic feeding and improving the production efficiency of the device; 2. For this automatic feeding device for stamping and forming of automatic sheet metal parts, through the fixing structure, after the sheet metal part is placed above the stamping table, driven by the second motor, its output shaft drives the double-threaded lead screw to rotate. Since the bottoms of the two moving blocks are in contact with the workbench, the two moving blocks can be driven to move in opposite directions on its outer surface when the double-threaded lead screw rotates, so that the two groups of fixing rods can clamp and fix the sheet metal part above the stamping table, avoiding the position deviation of the sheet metal part during the stamping process, thereby improving the quality of the production output; 3. For the automatic feeding device for stamping forming of sheet metal parts, through the pushing structure, when the negative pressure suction cup places the stamped sheet metal parts on the top of the blanking table, driven by the third motor, its output shaft can drive the rotating rod to rotate. Due to the hinge connection between the hinge rod and the rotating rod, the second sliding rod can reciprocate in the first support plate, so that the push plate can push the sheet metal parts onto the top of the inspection table, facilitating the quality inspection of the sheet metal parts by the staff.

[0020] Please refer to Figure 6-7, first through grooves 21 are formed on both inner sides of the stamping table 2, and an empty groove is formed inside the stamping table 2. A fixing structure 9 is fixedly installed in the empty groove inside the stamping table 2. The fixing structure 9 includes two second support plates 91. A second fixing ring 92 is fixedly installed on one side of a second support plate 91. A second motor 93 is fixedly installed inside the second fixing ring 92. One end of the output shaft of the second motor 93 is fixedly installed with a double-threaded lead screw 94. The double-threaded lead screw 94 is rotatably connected to the other second support plate 91. Two moving blocks 95 are threadedly installed on both sides of the outer surface of the double-threaded lead screw 94. The bottoms of the two moving blocks 95 are slidably connected to the top of the workbench 1. Two fixing rods 96 are fixedly installed on both sides of the tops of the two moving blocks 95. The two fixing rods 96 are slidably connected to the first through grooves 21.

[0021] After the sheet metal part is placed above the stamping table 2, driven by the second motor 93, its output shaft can drive the double-threaded lead screw 94 to rotate. Since the bottoms of the two moving blocks 95 are in contact with the workbench 1, the two moving blocks 95 can be driven to move in opposite directions on its outer surface simultaneously when the double-threaded lead screw 94 rotates, so that the two groups of fixing rods 96 can clamp and fix the sheet metal part above the stamping table 2.

[0022] Please refer to Figure 2 and Figure 8 , a pushing structure 10 is fixedly installed on one side of the blanking table 4. The pushing structure 10 includes a fixing plate 101 and a first support plate 102. A third fixing ring 103 is fixedly installed on the top of the fixing plate 101. A third motor 104 is fixedly installed inside the third fixing ring 103. One end of the output shaft of the third motor 104 is fixedly installed with a rotating rod 105. One end of the rotating rod 105 is hingedly installed with a hinged rod 106. One end of the hinged rod 106 is hingedly installed with a second sliding rod 107.

An inspection table 5 is fixedly installed on one side of the outer surface of the blanking table 4. Legs 6 are fixedly installed below the workbench 1 and the inspection table 5.

[0023] When the negative pressure suction cup 86 places the stamped sheet metal part on the top of the blanking table 4, driven by the third motor 104, its output shaft can drive the rotating rod 105 to rotate. Due to the hinge between the hinged rod 106 and the rotating rod 105, the second sliding rod 107 can reciprocate in the first support plate 102, so that the push plate 108 can push the sheet metal part onto the top of the inspection table 5, which is convenient for the staff to perform quality inspection on the sheet metal part.

[0024] Working principle: When an automatic feeding device for stamping forming of sheet metal parts is in use, first stack the sheet metal parts on the top of the stacking table 3. When stamping the sheet metal parts, driven by the first motor 817, its output shaft drives the pulley 813 to rotate, so that the linkage belt 814 drives the connecting block 815 to move. Thus, the connecting block 815 drives the first sliding rod 82 to slide inside the fixed slide rail 81, so that the negative pressure suction cups 86 on both sides move above the stamping table 2 and the stacking table 3. Subsequently, driven by two electric cylinders 87, the two telescopic rods drive the negative pressure generator 85 to slide downward inside the mounting plate 84 at the same time, so that the negative pressure suction cups 86 above the stacking table 3 contact the sheet metal parts, and the negative pressure suction cups 86 above the stamping table 2 contact the stamped sheet metal parts. Driven by the negative pressure generator 85, the sheet metal parts are adsorbed. Then, driven by the first motor 817 again, the two negative pressure suction cups 86 are moved above the stamping table 2 and the blanking table 4, so as to place the unstamped sheet metal parts above the stamping table 2 and place the stamped sheet metal parts above the blanking table 4. At the same time, after the sheet metal parts are placed above the stamping table 2, driven by the second motor 93, its output shaft drives the double-threaded lead screw 94 to rotate. Since the bottoms of the two moving blocks 95 are in contact with the workbench 1, the two moving blocks 95 can be driven to move in opposite directions on its outer surface when the double-threaded lead screw 94 rotates, so that the two groups of fixed rods 96 clamp and fix the sheet metal parts above the stamping table 2 to prevent the position of the sheet metal parts from shifting during stamping. Finally, when the negative pressure suction cup 86 places the stamped sheet metal parts on the top of the blanking table 4, driven by the third motor 104, its output shaft drives the rotating rod 105 to rotate. Due to the hinge between the hinge rod 106 and the rotating rod 105, the second sliding rod 107 can reciprocate in the first support plate 102, so that the push plate 108 can push the sheet metal parts onto the top of the inspection table 5, which is convenient for the staff to conduct quality inspection on the sheet metal parts.
