Description

Technical Field

[0001] The utility model relates to the technical field of metal stamping, in particular to a flexible and continuous stamping die. Background Art

[0002] The continuous stamping die is a common tool used for stamping and manufacturing metal products. It can obtain complex workpieces through orderly punching, embossing and bending operations. In actual production, it is occasionally encountered that the product is a left-right part, that is, the product is divided into two independent parts, the left component and the right component. The left component and the right component may have mirror symmetry or asymmetry in structure, and the number may be equal or unequal. If the number is equal, in order to reduce the number of molds, the preferred manufacturing method is the one-out-two method, that is, a connecting part located in the middle is designed on the same material strip, and then the processing areas of the left component and the right component are designed on both sides of the connecting part respectively. In this way, the same connecting part is used to guide the material when the material strip is deformed, and the left component and the right component are processed through the same number of processing stations to obtain a group of products. This method saves the width of the material strip compared to the one-out-one method. However, if the number of left components and right components is not equal, one type of component must continue to be processed. However, for the one-out-two mold, it already has the part to complete the processing of the component, and it is a waste to open another set of molds.

[0003] Therefore be necessary to improve the structure of continuous stamping die to solve the above problems. Utility Model Content

[0004] The main purpose of the utility model is to provide a flexible continuous stamping die, which can meet the special occasions of producing left and right parts with inconsistent numbers of left and right parts, which is beneficial to reducing mold opening costs and improving processing efficiency.

[0005] The utility model achieves the above-mentioned purpose through the following technical scheme: a flexible change-type continuous stamping die, including an upper die, a lower die and a plurality of processing stations arranged on the lower die in sequence along the conveying direction of the material belt, the lower die includes two rows of floating guide blocks located on both sides of the conveying direction of the material belt, and a row of detachable floating guide blocks is provided in the middle part of the lower die along the conveying direction of the material belt, and the floating guide blocks and the detachable floating guide blocks are both provided with pressing surfaces for pressing the material belt.

[0006] Specifically, the feeding side of the lower die is provided with supporting blocks respectively aligned with the two rows of floating guide blocks, and the feeding side of the lower die is also provided with detachable blocks aligned with the detachable floating guide blocks.

[0007] Specifically, a blanking slide plate is provided on the discharge side of the lower die.

[0008] Furthermore, baffles are provided on both sides of the blanking slide plate, and the baffles are located outside the two rows of floating guide blocks.

[0009] The beneficial effects of the technical solution of the utility model are:

[0010] The utility model can be applied to a one-out-two stamping process when the detachable floating guide block is removed, and can be applied to a one-out-one stamping process when the detachable floating guide block is installed, meeting the special occasions where the product requires left and right parts but the numbers of left and right parts are inconsistent, which is beneficial to reducing mold opening costs and improving processing efficiency.

[0017] The utility model is further described in detail below in conjunction with specific embodiments.

[0018] Example:

[0019] like Figures 1 to 3 As shown, a flexible changeable continuous stamping die of the utility model comprises an upper die, a lower die 1 and a plurality of processing stations 11 sequentially arranged on the lower die 1 along the conveying direction of the material belt, the lower die 1 comprises two rows of floating guide blocks 12a located on both sides of the conveying direction of the material belt, a row of detachable floating guide blocks 12b are arranged in the middle part of the lower die 1 along the conveying direction of the material belt, and both the floating guide blocks 12a and the detachable floating guide blocks 12b are provided with a pressing surface 121 for pressing the material belt.

[0020] The continuous stamping die can be used in a one-out-two stamping process when the detachable floating guide block 12b is removed. At this time, the detachable floating guide block 12b is not installed on the lower die 1, and the material strip adopts a wide material strip. The two sides of the wide material strip are guided by two rows of floating guide blocks 12a. The entire processing process relies on the middle connection, and the left component 2a and the right component 2b are connected in the middle and then pulled to move. The left half of the processing station 11 in the moving direction is used to form the left component 2a, and the right half is used to form the right component 2b, and finally the materials are dropped together. This continuous stamping die is used in a one-in-one stamping process when equipped with a detachable floating guide block 2b. In this embodiment, the number of left components 2a is greater than that of right components 2b, and the material strip is replaced with a narrow material strip. The connecting part is on the right side of the narrow material strip and is limited by a detachable floating guide block 12b. The left part is still used to form the left component 2a and is still limited by a row of floating guide blocks 12a. The structure of the processing station 11 remains unchanged, but the right half is not put into use, and the left half is still processed, eliminating a mold. Therefore, the utility model meets the special occasions where the product requires left and right parts but the number of left and right parts is inconsistent, realizes flexible mold change, is conducive to reducing mold opening costs, and improves processing efficiency. Because in the one-out-two process, the detachable floating guide block 12b will interfere with the transportation of the wide material strip, so it must be removed at this time.

[0021] like Figure 1 and Figure 2 As shown, the feeding side of the lower mold 1 is provided with supporting blocks 13a respectively aligned with the two rows of floating guide blocks 12a, and the feeding side of the lower mold 1 is also provided with detachable blocks 13b aligned with the detachable floating guide blocks 12b.

[0022] The material strip of the planar structure also needs to be limited in advance before entering between the upper and lower molds, and the material guide is not between the upper and lower molds, which makes the operation safer. The material support block 13a has a lower support surface and an outer blocking surface. For wide material strips, the two sides are limited in the middle by two blocking surfaces, and the lower part is supported by two supporting surfaces; for narrow material strips, the bottom only needs to be supported by one supporting surface, and the two sides are limited by a blocking surface and a detachable block 13b, which also plays a complete limiting effect. Because in the one-out-two process, the detachable block 13b will interfere with the conveying of the wide material strip, so it needs to be removed at this time.

[0023] like Figure 1 As shown, a blanking slide plate 14 is provided on the discharge side of the lower die 1 , baffle plates 141 are provided on both sides of the blanking slide plate 14 , and the baffle plates 141 are located outside the two rows of floating guide blocks 12 a .

[0024] After the continuous stamping die completes all processing, the left component 2a and the right component 2b are both dropped, and the drop slide 14 can make them slide into the same aggregate container to avoid direct drop collision force causing product damage. The baffle 141 limits the drop range to ensure that all products can fall into the aggregate container.

[0025] The above are only some embodiments of the present invention. For those skilled in the art, several modifications and improvements can be made without departing from the inventive concept of the present invention, which all belong to the protection scope of the present invention.
