[0026] In this embodiment, the lifting plate 23 is moved downward along the fixed frame 21 under the action of the hydraulic cylinder 22, so that the upper mold 24 is engaged with the lower mold 25 to punch the workpiece blank. At the same time, the workpiece blank is pressed under the action of the edge protrusion of the mold.

[0027] Example 2

[0028] like Figure 1-5 As shown, on the basis of Example 1, the utility model provides a technical solution: preferably, the loading and unloading mechanism 3 includes a mounting plate 31, the bottom of the mounting plate 31 is fixedly connected to the top of the support frame 1, a motor 32 is fixedly connected to one side of the mounting plate 31, a threaded rod 33 is fixedly connected to one end of the rotating shaft of the motor 32, a driving plate 34 is threadedly connected to the surface of the threaded rod 33, a cylinder 35 is fixedly connected to the top of the driving plate 34, a picking plate 36 is fixedly connected to the output end of the cylinder 35, a suction cup 37 is fixedly connected to the bottom of the picking plate 36, a vacuum pump 38 is fixedly connected to the top of the driving plate 34, and the inner cavities of the vacuum pump 38, the picking plate 36 and the suction cup 37 are connected.

[0029] In this embodiment, under the action of the motor 32, the threaded rod 33 rotates to move the drive plate 34 along the threaded rod 33, thereby moving the picking plate 36 to the top of the workpiece blank, and then under the action of the cylinder 35, the picking plate 36 moves down, and the suction cup 37 contacts the surface of the workpiece blank. Under the action of the vacuum pump 38, the air inside the suction cup 37 and the picking plate 36 is extracted, and the workpiece blank is picked up under the action of atmospheric pressure. Then, the threaded rod 33 rotates to move the workpiece blank to the top of the lower mold 25, and then the workpiece blank is placed inside the lower mold 25 for stamping and edge pressing.

[0030] Example 3

[0031] like Figure 1-5 As shown, on the basis of Example 1, the utility model provides a technical solution: preferably, the iron chip removal mechanism 4 includes a fixed rod 41, one end of the fixed rod 41 is fixedly connected to one side of the picking plate 36, the other end of the fixed rod 41 is fixedly connected to a magnetic plate 42, the inner wall of the magnetic plate 42 is fixedly connected to a metal column 43, the bottom of the metal column 43 is fixedly connected to a collecting plate 44, the surface of the metal column 43 is sleeved with a coil 45, the top of the magnetic plate 42 is fixedly connected to an electric controller 46, one end of the support frame 1 is fixedly connected to a slot 47, and a collection box 48 is inserted into the interior of the slot 47.

[0032] In this embodiment, when the picking plate 36 moves to the top of the workpiece, the coil 45 is energized through the electric controller 46, so that the metal column 43 is magnetic, and then the collecting plate 44 is magnetic. When passing over the lower mold 25, the metal debris on the surface of the lower mold 25 is sucked and collected.

In the process of returning, the metal debris in the groove of the lower mold 25 is sucked and collected by the collecting plate 44 to avoid the accumulation of metal debris in the lower mold 25 and affecting the processing accuracy. When the surface of the collecting plate 44 absorbs too much metal debris, the collecting plate 44 is moved to the top of the collecting box 48, and the coil 45 is powered off to make the collecting plate 44 lose its magnetism. The metal debris can fall into the collecting box 48 for collection, making it more convenient to use.

[0033] The following is a detailed description of the working principle of the automotive mold edge pressing structure.

[0034] like Figure 1-5 As shown, when the automobile parts are pressed, under the action of the motor 32, the threaded rod 33 rotates to make the driving plate 34 move along the threaded rod 33, so that the picking plate 36 moves to the top of the workpiece blank, and then under the action of the cylinder 35, the picking plate 36 moves down, the suction cup 37 contacts the surface of the workpiece blank, and under the action of the vacuum pump 38, the air inside the suction cup 37 and the picking plate 36 is extracted, and under the action of atmospheric pressure, the workpiece blank is picked up, and then the threaded rod 33 rotates to move the workpiece blank to the top of the lower mold 25, and then the workpiece blank is placed inside the lower mold 25, and then under the action of the hydraulic cylinder 22, the lifting plate 23 moves downward along the fixing frame 21, so that the upper mold 24 is meshed with the lower mold 25, and the workpiece blank is punched. At the same time, under the action of the protrusion on the edge of the mold, the workpiece blank is pressed. After the pressing is completed, the workpiece blank is taken out. When the taking plate 36 moves to above the workpiece, the coil 45 is energized through the electric controller 46, so that the metal column 43 has magnetism, and then the collecting plate 44 has magnetism. When passing above the lower mold 25, the metal debris on the surface of the lower mold 25 is sucked and collected. After the taking plate 36 takes the workpiece out of the lower mold 25 and places it on the other end of the support frame 1 surface, it returns to above the workpiece blank and takes the workpiece blank again for stamping and edge pressing. In the process of returning, the metal debris in the groove of the lower mold 25 is sucked and collected by the collecting plate 44 to avoid the accumulation of metal debris in the lower mold 25 and affecting the processing accuracy. When the surface of the collecting plate 44 absorbs too much metal debris, the collecting plate 44 is moved to the top of the collecting box 48, and the coil 45 is powered off to make the collecting plate 44 lose its magnetism. The metal debris can fall into the collecting box 48 for collection, making it more convenient to use.
