With the development of science and technology, most stamping part manufacturers have realized automated production. Wiring terminals are gradually widely used in various fields, including signal terminals, power terminals, connection terminals, etc., and are connection ends in circuits. A continuous die is a type of die used in the stamping process, which can complete multiple processes in one stamping stroke. In a continuous die, the processing of metal terminals is usually input in the form of a strip, and the die is designed with multiple stations, and each station performs different processing steps, such as blanking, bending, forming, etc. As the die moves, the strip advances through each station until the processing of the entire product is completed. The design of the continuous die can significantly improve production efficiency, reduce material waste, and is suitable for mass production of complex metal parts. Currently, continuous dies are widely used in the processing of metal terminals.

[0003] Currently, when metal terminals are processed by a continuous die, in order to improve the processing and forming efficiency of metal terminals, the strip of metal terminals moves and operates on the continuous die. And how to ensure the stable cooperation between the strip and the continuous die during the moving processing is a technical problem that needs to be solved currently. When the strip cooperates with the continuous die for moving processing currently, the strip is prone to deviation problems. A certain deviation amount is likely to affect the forming quality of the terminals, and the initial state of the strip feeding is mostly in a coiled state, and the straightness problem of the strip will also affect the processing quality.

[0023] With reference to Figures 1 - 4, the present utility model provides a continuous die for integrally forming metal terminals, including a die base 1, a continuous die lower die 2 is arranged on the die base 1, a continuous die upper die 3 is arranged above the continuous die lower die 2, and the continuous die lower die 2 presses on the continuous die upper die 3 to stamp and form metal terminals on the metal terminal strip. A main strip board 4 is arranged on one side of the continuous die lower die 2. The main strip board 4 needs to be installed on the installation surface during use. The main strip board 4 can provide feeding support for the metal terminal strip. A pressing plate 5 is arranged above the main strip board 4. Both the main strip board 4 and the pressing plate 5 are arranged in a concave structure, so as to reserve an installation area. A first telescopic device 6 is arranged on the top of the pressing plate 5. The first telescopic device 6 can adopt a telescopic motor, which can provide lifting power for the pressing plate 5. When the first telescopic device 6 is in use, it needs to be installed on the installation surface. Transfer rollers 7 and straightening rollers 8 are rotatably connected to the opposite surfaces of the main strip board 4 and the pressing plate 5. In this application, the transfer roller 7 can adopt a rubber material as the roller body, and the rubber roller body can improve the friction force, so as to facilitate the transmission of the metal terminal strip to move. The straightening roller 8 can adopt a metal roller body, so as to facilitate the pressure plasticity of the metal terminal strip and adjust the straightness of the metal terminal strip.

[0024] A second telescopic device 11 is arranged on the top of the continuous die upper die 3. The second telescopic device 11 needs to be installed on the installation surface during use. The second telescopic device 11 can adopt a telescopic motor, which can provide stamping power for the continuous die upper die 3.

[0025] A secondary strip board 12 is arranged on the other side of the continuous die lower die 2. The secondary strip board 12 needs to be installed on the installation surface during use. The secondary strip board 12 is movably connected to the metal terminal strip. The secondary strip board 12 can be used to receive the stamped metal terminal strip. At this time, the metal terminal strip is in the blanking state.

[0026] The straightening roller 8 is centrally arranged on the main strip board 4, the transfer roller 7 is arranged on one side of the straightening roller 8, and the transfer roller 7 and the straightening roller 8 are used to transmit the metal terminal strip. A driving device 71 for driving the transfer roller 7 to rotate is arranged on the pressing plate 5. In this application, the driving device 71 can adopt a combination of a motor and a belt transmission mechanism, so as to facilitate the transmission of the transfer roller 7 to rotate, so as to make the metal terminal strip move for feeding.

[0027] The number of the transmission rollers 7 and the straightening rollers 8 is set to be several. The driving device 71 is used to drive one of the transmission rollers 7 to rotate. The transmission roller 7 can be used to clamp the metal terminal strip for limiting transmission, so as to increase the effect of pair transmission and deviation correction of the metal terminal strip. When the metal terminals in the transmission state pass through the straightening rollers 8 distributed up and down, the straightening rollers 8 can act on the metal terminal strip with pressure, and plastically deform the metal terminal strip through the pressure. When local warping and bending problems occur during the feeding of the metal terminal strip, the straightness of the metal terminal strip can be guaranteed in this way.

[0028] A deviation correction roller 9 is arranged below the pressing plate 5. The deviation correction roller 9 is in rolling contact with the metal terminal strip. A deviation correction and alignment mechanism 10 connected to the deviation correction roller 9 is arranged on the pressing plate 5. The deviation correction roller 9 can also be made of a metal roller body. When the deviation correction roller 9 limits the side surface of the metal terminal strip, the durability of the structure can be improved.

[0029] The number of the deviation correction and alignment mechanisms 10 is at least one pair. The deviation correction and alignment mechanism 10 includes a pair of bearing seats 101. The bearing seats 101 are fixedly connected to the top of the pressing plate 5. A bidirectional lead screw 102 is rotatably connected to the pair of bearing seats 101.

[0030] The bottom of each threaded sleeve 103 is fixedly connected with a roller seat 91, and the roller seat 91 is slidably connected to the bottom position of the pressing plate 5. The number of the deviation correction rollers 9 is the same as that of the roller seats 91. The deviation correction roller 9 is rotatably connected to the bottom of the roller seat 91. The deviation correction roller 9 can perform rolling limit on the side surface of the metal terminal strip in the horizontal direction.

[0031] A moving groove 51 is formed in the pressing plate 5. The roller seat 91 passes through the moving groove 51 and is connected to the threaded sleeve 103. The moving groove 51 can provide a moving path for the position of the roller seat 91, so as to facilitate the adjustment of the position of the deviation correction roller 9.

[0032] Specifically, when the pressing plate 5 drives the transmission roller 7 and the straightening roller 8 to press on the metal terminal strip for transmission and straightening, the bidirectional lead screw 102 can be controlled to rotate at this time. By virtue of the setting that the roller seat 91 slides at the bottom of the pressing plate 5, the pair of threaded sleeves 103 can perform a linear motion of approaching or separating from each other. By adjusting the positions of the pair of deviation correction rollers 9 so as to correspond to both sides of the metal terminal strip, combined with the limit of the metal terminal strip in the vertical direction by the transmission roller 7 and the straightening roller 8, when the metal terminal strip moves and is fed between the lower die 2 of the progressive die and the upper die 3 of the progressive die for continuous stamping processing, the limit in the horizontal and vertical directions can improve the stability of the movement of the metal terminal strip, so that the metal terminal strip can be stably formed during the terminal processing.
