Description

Technical Field

[0001] The utility model relates to the field of stamping equipment, in particular to a continuous stamping device. Background Art

[0002] According to their structural characteristics, stamping dies can be divided into three major categories: single-process dies, compound dies, and progressive dies. Since single-process dies and compound dies require more manual participation during the operation process, they do not have an advantage in terms of economic benefits. In contrast, progressive dies can achieve large-scale production and significantly improve production efficiency. When designing a progressive die, it is necessary to carefully consider the spacing between each module, the machining accuracy of parts, the assembly accuracy, the mating accuracy, and possible interference problems. The precise control of these factors is crucial for realizing the automation and large-scale production of progressive dies.

[0003] However, the existing continuous stamping equipment needs to perform positioning detection every time a workpiece is placed, which is relatively time-consuming. In addition, in order to pick up the workpiece at each station, it is usually necessary to set up a manipulator separately, which not only increases the operation complexity of the equipment, but also makes the overall floor area of the equipment larger, affecting the utilization efficiency of the production space.

[0051] A punching mechanism 600 includes a bracket 610 and a punching machine 620. The bracket 610 is arranged on the upper die 200, and the punching machine 620 is arranged on the bracket 610. The punching machine 620 is used to process the positioning hole.

[0052] According to an embodiment of the present invention, by such an arrangement, at least some of the following effects can be achieved: through the mutual cooperation of the upper mold 200 and the lower mold 100, the workpiece can be stamped into a corresponding shape, the waste trough 110 extends in the up-down direction, and the cut material is collected through the waste trough 110; the first floating pin 410 and the second floating pin 420 are successively arranged on one side of the conveying line 300, and the third floating pin 430 is arranged on the other side of the conveying line 300. Different floating pins are arranged on both sides of the conveying line 300. Through the cooperation of the card slots 411 on both sides, the workpiece can be installed in the card slot 411 so that the workpiece can pass along the card slot 411; the floating pin extends along the up-down direction and can be inserted into the upper mold 200 without interfering with the cooperation of the upper mold 200 and the lower mold 100; multiple first floating pins 410, multiple second floating pins 420 and the third floating pin 430 are arranged along different straight lines respectively, and the first distance between the first straight line and the third straight line, The second distance is between the second straight line and the third straight line, and the second distance is the width of the unprocessed workpiece. The workpiece is inserted into the slot 411 between the second floating lift pin 420 and the third floating lift pin 430, so that the workpiece is transported along the second floating lift pin 420 and the third floating lift pin 430. Since the first distance is greater than the second distance, the end of the workpiece can abut the first floating lift pin 410, and the corresponding position is cut by the side blade 210 on the upper mold 200. The corresponding position of the side blade 210 is located at the intersection. It can be understood that it is the position where the end of the workpiece abuts the first floating lift pin 410 to cut the workpiece at the corresponding position. After cutting, the width of the workpiece is equal to the first distance, and the width of the uncut part is still the second distance. When the workpiece continues to work, the workpiece continues to be pushed along the conveying line 300. The end of the cutting part abuts the first floating lift pin 410. By cutting the same length each time, the moving distance of the workpiece each time is controlled to achieve rapid preliminary positioning of the workpiece.

[0053] The positioning punch rod 220 cooperates with the positioning hole 120 to punch out a positioning hole on the workpiece, thereby realizing secondary positioning of the workpiece;

[0054] The punching mechanism 600 can punch holes for the mold. The puncher 620 of the punching mechanism 600 is provided with a positioning port for fine machining, which can be grinding or drilling threads and other steps. The bracket 610 is provided on the upper mold 200 and moves up and down with the upper mold 200. The bracket 610 can assist in supporting the workpiece and is also used to install the puncher 620. When the bracket 610 descends, the puncher 620 also descends. The puncher 620 can be inserted into the positioning hole to position the workpiece, and then the positioning hole is finely machined by the puncher 620; the floating pin is initially positioned, the positioning punch 220 punches the positioning hole, and the puncher 620 positions the positioning hole. The triple positioning effectively improves the processing accuracy.

[0055] It can be understood that the lifting pin includes a supporting part and an elastic part. The clamping groove 411 is provided on the supporting part, the elastic part is provided on the lower die 100, the supporting part is arranged on the elastic part, and the elastic part drives the supporting part to move upward from bottom to top through elastic force. When the upper die 200 presses down, the upper die 200 will also drive the supporting part to move downward, causing the workpiece to move downward. When the upper die 200 rises, the workpiece is driven upward by elastic force, and the workpiece is separated from the lower die 100, enabling the workpiece to continue to be transported along the conveying direction.

[0056] The elastic part can be a spring.

[0057] It can be understood that the structures of the multiple first lifting pins 410, the multiple second lifting pins 420, and the third lifting pin 430 are the same, and the only difference lies in their positions.

[0058] It can be understood that the conveying line 300 is not a conveyor belt in the traditional sense. Here, the conveying line 300 is for the convenience of understanding. The multiple first lifting pins 410, the multiple second lifting pins 420, and the third lifting pin 430 on both sides of the conveying line 300 are arranged along the transportation direction of the conveying line 300 for transporting workpieces.

[0059] It can be understood that the first direction, the second direction, and the third direction are arranged along the direction of the conveying line 300 and are parallel to each other.

Through the cooperation of the lifter pins and the guide grooves 250, the upper die 200 and the lower die 100 can fit together, enabling better stamping of workpieces.

[0066] In some embodiments, the upper die 200 and the lower die 100 are correspondingly provided with multiple stations, and the length of a single station is equal to the length of the side cutter 210. The processing steps corresponding to each station are different.
