Technical Field

[0001] The utility model relates to a feeding structure, in particular to a pressing and holding feeding structure of a stamping device, belonging to the technical field of stamping auxiliary devices. Background Art

[0002] Metal gaskets are made of high-precision, high-hardness sheet materials. They are usually used in the adjustment and measurement of precision molds or precision hardware, or as pads. They are called precision gaskets, sometimes also called mold gaskets or precision gap pieces. In the production process of some metal gaskets, a stamping machine is required to stamp the metal sheets.

[0003] However, in the process of stamping metal sheets, most of the time, the workers move the sheets by hand. In the process of manually moving the sheets, since the hands are close to the stamping die, they may accidentally put their hands into the bottom of the stamping die, which may easily cause safety accidents, resulting in poor safety of use. In addition, when the stamping machine stamps the sheet, it will also generate certain vibrations. These vibrations will be transmitted to the operator's hands through the sheet, which may easily cause discomfort to the operator's hands, thereby resulting in poor comfort of use.

The top of the connecting frame 4 is threadedly connected to a screw rod 506, and the bottom end of the screw rod 506 is rotatably connected to a sliding frame 507. The top end of the screw rod 506 is slidably connected to a rotating rod 505, and the sliding frame 507 is rotatably connected to multiple second conveying shafts 508, and the sliding frame 507 is slidably connected to the connecting frame 4.

[0023] As a technical optimization solution of the utility model, Figure 1 As shown, the rotating rod 505 is perpendicular to the screw rod 506 , and the cross section of the end of the rotating rod 505 is in a T-shaped structure, so the screw rod 506 can be easily rotated by the rotating rod 505 .

[0024] As a technical optimization solution of the utility model, Figure 1 and Figure 4As shown, multiple first conveying axes 502 are linearly equidistantly distributed, multiple second conveying axes 508 are linearly equidistantly distributed, the distance between two adjacent first conveying axes 502 is equal to the distance between two adjacent second conveying axes 508, the width at both ends of the cross section of the first conveying axis 502 is smaller than the width in the middle, and the width at both ends of the cross section of the second conveying axis 508 is smaller than the width in the middle. Therefore, the metal sheet can be clamped by the multiple first conveying axes 502 and the second conveying axes 508, and the metal sheet can be conveyed by the simultaneous rotation of the multiple second conveying axes 508.

[0025] As a technical optimization solution of the utility model, Figure 1 and Figure 3 As shown, the cross-section of the guide column 2 is T-shaped, the cross-section of the sliding frame 507 is U-shaped, the top end of the spring 3 is in contact with the connecting frame 4, and the bottom end of the spring 3 is in contact with the base 1, so the connecting frame 4 can be reset under the action of the spring 3.

[0026] As a technical optimization solution of the utility model, Figure 1 As shown, the base 1 is provided with two through slots 7 , and the two through slots 7 are symmetrically distributed about the middle of the base 1 , so the base 1 can be installed and fixed by means of the through slots 7 and bolts.

[0027] As a technical optimization solution of the utility model, Figure 1 and Figure 3 As shown, a positioning structure 6 is provided on the connecting frame 4, and the positioning structure 6 includes a knob 601 and a screw rod 602. The connecting frame 4 is rotatably connected with the screw rod 602, and two baffles 603 are threadedly connected to the screw rod 602.

The baffle 603 is rotatably connected with a baffle shaft 604, and one end of the screw rod 602 is fixedly connected with a knob 601, and the threads at both ends of the screw rod 602 are in opposite directions. The cross-section of the baffle 603 is an L-shaped structure, and the side of the baffle shaft 604 extends to the outside of the baffle 603. Therefore, the metal sheet can be positioned by the two baffle shafts 604, thereby preventing the metal sheet from shifting in position during the transportation process, thereby effectively improving the stability of use.

[0028] When the utility model is in use, the base 1 can be installed to one side of the stamping die through the two through slots 7 and the matching bolts. When the metal sheet needs to be stamped, the metal sheet can be placed between the first conveying shaft 502 and the second conveying shaft 508, and one end of the metal sheet can be located at the bottom end of the stamping die. When placing the metal sheet, the metal sheet can be placed between the two blocking shafts 604, thereby playing a role in positioning the metal sheet, and by turning the knob 601, the knob 601 drives the screw rod 602 to rotate, and the screw rod 602 threads drive the two baffles 603 to slide on the guide rod 605, and the movement of the baffle 603 drives the blocking shaft 604 to move, thereby achieving By adjusting the positions of the two stop shafts 604, metal sheets of different widths can be positioned, thereby effectively improving the flexibility of use. After placement, there is a certain distance between the bottom end of the metal sheet and the stamping die, which facilitates the movement of the metal sheet. After the position of the metal sheet is adjusted, the screw 506 can be rotated by the rotating rod 505. The rotation of the screw 506 will drive the sliding frame 507 to move. The sliding frame 507 drives the multiple second conveying shafts 508 to move toward the metal sheet. When the multiple second conveying shafts 508 are in contact with the metal sheet, the rotating rod 505 is stopped, and the clamping and fixing of the metal sheet is achieved. Then the punching machine can be started to punch the sheet. During the punching process, the punching die will drive the metal sheet to move a certain distance until the metal sheet and the punching die collide with each other. At this time, the connecting frame 4 will slide on the two guide pillars 2, and the two springs 3 will shrink at the same time. When one punching is completed, the punching die will be reset. At this time, the button switch 509 can be pressed once. After the button switch 509 is pressed once, the output shaft of the motor 501 will rotate at a specified angle. The rotation of the output shaft of the motor 501 drives one of the synchronous wheels 503 to rotate. Since the same synchronous belt 504 is wound around the multiple synchronous wheels 503, when one of the synchronous wheels 503 rotates. The remaining synchronous wheels 503 will be driven to rotate through the synchronous belt 504. The simultaneous rotation of multiple synchronous wheels 503 will cause multiple first conveying shafts 502 to rotate simultaneously. The simultaneous rotation of multiple first conveying shafts 502 will convey the metal sheet for a specified distance. When the metal sheet is conveyed, the next stamping can be carried out. Therefore, repeating the above operation can realize automatic feeding during metal sheet stamping, avoiding the need to hold the metal sheet for movement, thereby effectively improving the safety and comfort of the stamping work. After the stamping of one end of the metal sheet is completed, the metal sheet can be flipped 180 degrees to stamp the other end of the metal sheet, thereby completing the entire stamping work of the metal sheet.
