Description
Technical Field
The utility model relates to the technical field of terminal processing dies, in particular to a continuous die for forming a terminal material strip through puncturing and bending.
Background
At present, the terminal is formed by stamping and bending in a material belt mode, and a stamping die is relatively common production equipment when the terminal material belt is produced and processed, wherein steel or copper strips are generally fed into the stamping die, and continuous terminal groups are obtained by stamping and bending.
For example: CN 202803917U discloses an automatic feeding continuous stamping die for a material belt type terminal and corresponding stamping equipment thereof, wherein the automatic feeding continuous stamping die for the material belt type terminal comprises an upper die and a lower die, the upper die and the lower die are in stamping fit connection, an automatic feeding device is arranged between the upper die and the lower die, and automatic feeding continuous stamping production is realized; the corresponding stamping equipment comprises a continuous stamping die for automatic feeding of the material belt type terminal, wherein the continuous stamping die for automatic feeding of the material belt type terminal is connected with an automatic discharging mechanism and an automatic receiving mechanism; the automatic feeding, continuous stamping and automatic material receiving full-automatic production is realized through the cooperative cooperation of the automatic discharging mechanism, the continuous stamping die and the automatic material receiving mechanism. When an operator starts a power supply during stamping, the stamping die continuously stamps the material belt, and the hardware terminal meeting the specification is stamped. The continuous stamping process of the stamping die is as follows: firstly, a sliding block movable positioning needle is inserted into a side hole of a material belt, an upper die is pressed down to drive a clamping plate inclined wedge block to be pressed down, a pushing inclined surface pushes the sliding block to slide inwards, the sliding block slides and simultaneously drives the sliding block movable positioning needle to slide, and the sliding block movable positioning needle pulls the material belt to advance towards the inner side of the die; after the upper die is stamped, the ascending process stops the needle withdrawing and inserting the side holes of the material belt, and the function of the needle withdrawing and inserting the side holes is to prevent the material belt from loosening and reversing when the upper die and the lower die are opened. Because the spring is pre-tensioned and compressed by the slide block in the process of die assembly, when the die is opened, the slide block movable positioning needle is separated from the side hole of the material belt, and the spring resets the slide block to the original position so as to prepare for the material pulling of the next round. The continuous stamping of the stamping die is realized through the continuous circulation process.
However, the press mold and the press apparatus are formed by one-time press bending, and are only suitable for terminal groups with relatively large sizes. For some precise terminal sets, because the distance between adjacent terminals is small, the size of each terminal is small, and the stamping die and the stamping equipment are not applicable, if the bending molding of the precise terminal set is required to be satisfied, the precise terminal set needs to be designed into two parts, each part is manufactured by stamping and bending respectively, and then the two parts are compounded into the precise terminal set, on one hand, the process is troublesome, on the other hand, the two parts are depended on two bending molding, and the compounding step is additionally added, so that the overall yield of the precise terminal set is limited, and is difficult to further promote.

Step 2, the first stripper insert 11 and the fourth lower mold insert 24 are pressed, specifically: the first stripper insert 11 goes downward, and the fourth lower mold insert 24 is pressed by the spring force of the upper mold, and simultaneously the material is pressed, so that the action before bending is completed. And 3, bending, namely enabling the first stripper plate insert 11 and the second stripper plate insert 12 to move downwards, pressing the material by using the spring force of the upper die, and enabling the fourth lower die insert to move downwards, so that the first stripper plate insert 11, the second stripper plate insert 12, the third lower die insert 23 and the second lower die insert 24 generate plastic deformation on the part of the material needing bending, and completing bending. And 4, when the die is at the bottom dead center, firstly, continuously moving the whole upper die downwards to the bottom dead center, and folding the bending part to be dead, and finally, finishing bending. And 5, the whole upper die of the die continues to move downwards at the upper dead point to reach the upper dead point, and the fourth lower die insert 24 moves upwards by utilizing the spring force of the lower die, so that the product is separated from the lower die bending part, and the bending process is completed.
The design focus of the utility model is that the upper die assembly is provided with an upper piercing assembly, a first stripper plate entering sub-assembly, a second stripper plate entering sub-assembly and a third stripper plate entering sub-assembly which are sequentially arranged along the machining direction; the lower die assembly is provided with a lower puncture assembly, a first lower die insert subassembly, a second lower die insert subassembly and a third lower die insert subassembly which are sequentially arranged along the machining direction; the lower puncture assembly, the first lower die insert subassembly, the second lower die insert subassembly and the third lower die insert subassembly are arranged opposite to the corresponding upper puncture assembly, the first stripper insert subassembly, the second stripper insert subassembly and the third stripper insert subassembly one by one. Therefore, the precise small-size terminal group with a plurality of terminals is subjected to piercing and bending forming on the same material belt, on one hand, the spacing between adjacent terminals can be better controlled by piercing and forming a plurality of terminal blanks before bending on the terminal plate belt, the terminal group products of the terminals closely arranged on the same material belt are suitable for three-step bending forming, and the terminal group products are more suitable for the precise small-size terminal group bending forming step by step, so that the problems that the precise small-size terminal group needs two groups of bending and compounding in the prior art are solved, the manufacturing Cheng Mafan and the yield rate are difficult to further improve and the like.
The foregoing description is only a preferred embodiment of the present utility model, and is not intended to limit the technical scope of the present utility model, so any minor modifications, equivalent changes and modifications made to the above embodiments according to the technical principles of the present utility model are still within the scope of the technical solutions of the present utility model.
