[0041] The left upper support surface 112 and the right upper support surface 113 are vertically opposite to the top surface of the left and right support members 22 to keep a first gap 26, and the left upper positioning surface 114 and the right upper positioning surface 115 are vertically opposite to the left lower positioning surface 212 and the right lower positioning surface 213 to keep a second gap 27. When stamping the terminal, the terminal strip is clamped between the upper positioning plate 11 and the support member 22, the first gap 26 is equal to the thickness of the terminal strip, and the left upper positioning surface 114 and the right upper positioning surface 115 are in contact with the top of the terminal strip, and the left lower positioning surface 212 and the right lower positioning surface 213 are in contact with the bottom of the terminal strip, or the left upper positioning surface 114 and the right upper positioning surface 115 on the upper side are in contact with the top of the terminal strip, and the left lower positioning surface 212 and the right lower positioning surface 213 on the lower side keep a small gap with the bottom of the terminal strip, or vice versa, the left upper positioning surface 114 and the right upper positioning surface 115 on the upper side keep a small gap with the top of the terminal strip, and the left lower positioning surface 212 and the right lower positioning surface 213 on the lower side are in contact with the bottom of the terminal strip, or both the upper side and the lower side keep a small gap, so that the second gap 27 is equal to 1 to 1.5 times (usually greater than 1 times) the thickness of the terminal strip. When horizontally conveying the terminal strip, the support member 22 is moved downward, so that the first gap 26 becomes larger, while the second gap 27 remains unchanged, ensuring that the left upper positioning surface 114 and the right upper positioning surface 115 are always positioned on the left and right sides of the terminal strip, avoiding the terminal strip from floating up and down too much during conveying, which affects the positioning accuracy and further affects the controllability of terminal forming precision.
[0042] Preferably, the left upper support surface 112, the right upper support surface 113, the left upper positioning surface 114, and the right upper positioning surface 115 are separately arranged at the respective positions.
[0043] Preferably, the left upper support surface 112 and the right upper support surface 113 protrude downward beyond the bottom ends of the left upper positioning surface 114 and the right upper positioning surface 115 (usually slightly protruding, so that when the upper die is lowered as a whole, the left upper support surface 112 and the right upper support surface 113 can be in contact with the left and right sides of the terminal strip, and the left upper positioning surface 114 and the right upper positioning surface 115 are slightly higher than the left upper support surface 112 and the right upper support surface 113, so that the left upper positioning surface 114 and the right upper positioning surface 115 keep a small gap with the top of the left and right sides of the terminal strip).
[0044] Preferably, the left upper support surface 112 and the right upper support surface 113 are respectively connected with floating springs, and the floating springs (not shown in the figure) provide upward and downward floating elastic force.
[0045] Preferably, each of the left upper support surface 112 and the right upper support surface 113 is connected with a lifting cylinder (not shown in the figure), and the height of the left upper support surface 112 and the right upper support surface 113 relative to the left upper positioning surface 114 and the right upper positioning surface 115 is controlled by the respective lifting cylinder. Generally, when the terminal material belt is horizontally transferred, the left upper support surface 112 and the right upper support surface 113 can be further controlled to slightly move upward to achieve the upward avoidance effect. When the terminal is punched, the left upper support surface 112 and the right upper support surface 113 are against the top of the terminal material belt. At this time, the left upper support surface 112 and the right upper support surface 113 can be flush with the left upper positioning surface 114 and the right upper positioning surface 115 (i.e., the same height), or slightly lower than the left upper positioning surface 114 and the right upper positioning surface 115.
[0046] The general working process of the embodiment will be described in detail below:
[0047] Firstly, the upper die module 10 and the lower die module 20 are in the open die state, and the terminal material belt is placed on the lower positioning plate 21 of the lower die module 20. At this time, the middle forming area of the terminal material belt is arranged corresponding to the second avoidance opening 211, the left and right side areas of the terminal material belt are on the top surfaces of the left and right support members 22, and the left and right side areas of the most edge of the terminal material belt are on the left lower positioning surface 212 and the right lower positioning surface 213.
[0048] Then, the upper die driving device drives the whole upper die module 10 to move downward (die closing), so that the left upper positioning surface 114 and the right upper positioning surface 115 are at a set height. At this time, the left upper positioning surface 114 and the right upper positioning surface 115 are arranged vertically above and below the corresponding left lower positioning surface 212 and the right lower positioning surface 213 to maintain the second gap 27. The left upper positioning surface 114 and the right upper positioning surface 115 respectively position the left and right edges of the terminal material belt from above and below. For the terminal material belt in a roll shape (the initial state is generally a steel belt or a copper belt with a plurality of positioning holes on the left and right edges), it is continuously punched and formed to obtain a continuous terminal material belt with terminals. The second gap 27 is continuously and stably maintained for a long period of time to perform terminal forming work.
[0049] When the terminal is formed, the die intermittently performs the stamping action and the horizontal conveying action; specifically, when the terminal is stamped, the support 22 is in the up state, the terminal strip is clamped between the upper positioning plate 11 and the support 22, the first gap 26 is equal to the thickness of the terminal strip, the action of the upper die assembly 12 and the lower die assembly makes the terminal stamping formed into different shapes, and during the stamping process, the left upper positioning surface 114 and the right upper positioning surface 115 and the corresponding left lower positioning surface 212 and the right lower positioning surface 213 respectively position the left and right edges of the terminal strip; when the terminal strip is horizontally conveyed, the support 22 is moved downward, so that the first gap 26 becomes larger, the upper die assembly 12 and the lower die assembly are reset, and the terminal strip is pulled horizontally by one station, during the conveying process of the terminal strip, the second gap 27 remains unchanged, so that the left upper positioning surface 114 and the right upper positioning surface 115 and the corresponding left lower positioning surface 212 and the right lower positioning surface 213 always position the left and right edges of the terminal strip, so that the terminal strip does not produce large up-down floating during the conveying of the terminal strip, and the positioning accuracy is not ideal, thereby affecting the controllability of the terminal forming accuracy.
[0050] The stamping action and the horizontal conveying action are repeated until a set amount of terminal stamping is completed.
[0051] When the die completes a stage of terminal stamping, the upper die driving device drives the upper die module 10 to move upward as a whole, at this time, the upper die module 10 is opened upward relative to the lower die module 20; in addition, if a fault occurs during the die working process, the upper die module 10 also needs to be opened upward relative to the lower die module 20 to check and repair the internal situation of the die.
[0052] The utility model discloses a design emphasis lies in, it mainly is through the structure design and cooperation of upper die module and lower die module, be provided with left upper support surface, right upper support surface, left upper positioning surface, right upper positioning surface on the upper die module;Be provided with left lower positioning surface, right lower positioning surface on the lower die module;Lower die pin drive device control lower die pin assembly optional action downward or upward to hide or protrude second avoiding mouth;Support drive device control support optional action downward or upward to hide or protrude corresponding left lower positioning surface, right lower positioning surface;Like this, during the stamping processing, ensure that left upper positioning surface, right upper positioning surface and corresponding left lower positioning surface, right lower positioning surface always position the left and right edges of the terminal strip, avoid when conveying the terminal strip, the terminal strip produces larger up-down floating and leads to that the positioning accuracy is not ideal, thereby influence the controllability of terminal forming accuracy.
[0053] Secondly, the trip is small, fast; thereby solve the overall movement of the upper die and lead to the gap between the upper die and the lower die is too large to appear floating and reduce the accuracy of positioning problem.
[0054] The above is only the preferred embodiment of the present application, and does not limit the technical scope of the present application in any way. Therefore, any minor modification, equivalent change and modification of the above embodiment according to the technical essence of the present application still falls within the scope of the technical solution of the present application.
