Description

Technical Field

[0001] The invention relates to the technical field of automobile parts processing, and in particular to a stamping device for automobile parts. Background Art

[0002] Stamping of auto parts is an important process in the automobile manufacturing process. When the metal sheet is subjected to external force, its internal crystal structure slips and dislocates, resulting in a change in the shape of the material. During the stamping process, pressure is applied to the sheet through the mold to form it in the mold cavity. When the stamping device is processing it, if the auto parts are placed on the stamping device by an industrial robot, although automatic loading and unloading can be achieved, for some small processing plants, the cost is high and a large amount of space is required for the industrial robot. In addition, debris is inevitably generated during the stamping process. If it is not cleaned up in time, it may be scattered around the factory and affect the factory environment.

[0020] like Figure 1-5 As shown, the present invention provides a stamping device for automobile parts, including a workbench 1, a stamping mechanism 5 and a blanking mechanism 6. The workbench 1 is provided with a base 2, and the four corners of the base 2 are respectively provided with fixing columns 3. The tops of all the fixing columns 3 are provided with the same top plate 4, and each fixing column 3 is fixed to the top plate 4 by a nut 31, so that the fixing column 3 and the top plate 4 are convenient for disassembly and assembly. The stamping mechanism 5 is arranged on the top plate 4 and is used for stamping automobile parts. The blanking mechanism 6 is arranged on the stamping mechanism 5 and is driven by the stamping mechanism 5 to blank the automobile parts after stamping.

[0021] It should be noted that the stamping mechanism 5 includes a die 51, a hydraulic cylinder 52, a lifting frame 53 and a punch 55. The die 51 is arranged on the base 2, the cylinder body of the hydraulic cylinder 52 is arranged on the top plate 4 and the lower end of its piston rod is provided with a lifting frame 53, the lifting frame 53 is slidably connected to the guide rod 54 on the die 51, and the punch 55 is arranged at the bottom of the lifting frame 53 and is opposite to the die 51.

[0022] In addition, the unloading mechanism 6 includes a fixed plate 61, a swing plate 63, a unloading brush 65, a driving plate 66 and an ejection assembly 67. The fixed plates 61 are provided with two and are symmetrically arranged at the bottom of the top plate 4. The sides of the two fixed plates 61 are rotatably connected to the swing plates 63 through the rotating shafts 62 respectively. The ends of the two swing plates 63 are connected to the same bracket 64. The unloading brush 65 is rotatably connected to the bracket 64. The side of each swing plate 63 is hinged with a driving plate 66 through a pin shaft. The upper end of the driving plate 66 is hinged to the lifting frame 53 through a pin shaft.

[0023] The ejection assembly 67 is arranged on the die 51 and ejects the stamped automobile parts from the die 51 under the drive of the rotating shaft 62. The ejection assembly 67 includes an upper connecting rod 671, a lower connecting rod 672, a slider 673 and a ejector rod 675. Each rotating shaft 62 is provided with an upper connecting rod 671. The end of the upper connecting rod 671 is hinged to the upper end of the lower connecting rod 672 through a pin. The lower end of the lower connecting rod 672 is hinged to the slider 673. The slider 673 is slidably connected to the side of the die 51. A fixing frame 674 extending into the die 51 is provided between the two sliders 673. A plurality of ejector rods 675 inserted into the grooves of the die 51 are evenly distributed on the fixing frame 674.

[0024] Specific implementation and principle:

[0025] During stamping, the automobile parts to be stamped are placed in the die 51, and then the piston rod of the hydraulic cylinder 52 is controlled to extend to drive the lifting frame 53 and the punch 55 to move downward along the guide rod 54, and the lifting frame 53 drives the driving plate 66 to rotate, and the driving plate 66 drives the swing plate 63 to rotate, so that the blanking brush 65 on the swing plate 63 rotates to the outside of the die 51. During the rotation of the blanking brush 65, the debris on the die 51 can be cleaned into the debris recovery box on the front side of the die 51;

[0026] At the same time, the rotating shaft 62 rotates and drives the slider 673 to move downward through the upper connecting rod 671 and the lower connecting rod 672, so that the top rod 675 on the fixing frame 674 is retracted into the concave mold 51;

[0027] Then, the punch 55 continues to move downward, and the automobile part is punched by the punch 55;

[0028] After the stamping of the automobile parts is completed, the piston rod of the hydraulic cylinder 52 is controlled to retract to drive the lifting frame 53 and the punch 55 to move upward, and the lifting frame 53 drives the driving plate 66 to rotate in the opposite direction, and the driving plate 66 drives the swing plate 63 to rotate in the opposite direction, so that the blanking brush 65 on the swing plate 63 rotates to the top of the die 51;

[0029] At the same time, the rotating shaft 62 rotates in the opposite direction, and drives the slider 673 to move upward through the upper connecting rod 671 and the lower connecting rod 672, so that the ejector rod 675 on the fixing frame 674 ejects the automobile parts in the die 51 upward, and sweeps the automobile parts into the collection box on the rear side of the workbench 1 for collection through the unloading brush 65.

[0030] To summarize, the present application uses a stamping mechanism 5 to stamp automobile parts. On the one hand, the unloading brush 65 of the unloading mechanism 6 rotates outward during stamping to clean the surface of the die 51 before stamping. On the other hand, the unloading brush 65 rotates inward during the return stroke of stamping and cooperates with the ejector rod 675 to eject the stamped automobile parts in the die 51, and sweep the automobile parts into the collection box on the rear side of the workbench 1 for collection. The whole process integrates the stamping of automobile parts, debris cleaning and unloading, saving factory costs.
