Description

Material belt terminal stamping forming system
Technical Field
The invention relates to the field of design of a terminal stamping and forming die, in particular to a stamping and forming mechanism for a material belt terminal with a required shape and a stamping and forming production process thereof.
Background
Referring to fig. 1 and 2, a stamping and forming die 10 generally used in a stamping and forming process of a material strap terminal in the industry includes a stamping and blanking die 11 and a bending and forming die 12, wherein the stamping and blanking die 11 is disposed near a die feeding end 13, and the bending and forming die 12 is disposed near a die discharging end 14. The existing stamping and forming production process of the material belt terminal is to stamp and bend a metal sheet material into the material belt terminal with the required shape. Specifically, a metal sheet material fed from a die feeding end 13 is punched and blanked in a punching and blanking die 11 to form a terminal material strip, and then, an electroplating portion and a supporting portion of each material strip terminal 20 in the terminal material strip are bent into a desired shape in a bending and forming die 12 and then discharged from a die discharging end 14, and the terminal material strip is wound in a reel to form a whole roll. Subsequently, the tape terminal 20 is subjected to plating and insert injection molding in a subsequent step.
Referring to fig. 3 and 4, the plated portion of the conventional tape terminal 20 is bent to form a bent portion. Specifically, the first plated portion 21, the second plated portion 22 and the third plated portion 23 as shown in fig. 3 are bent to form a first bent portion 21A, a second bent portion 22A and a third bent portion 23A as shown in fig. 4; the first bending part 21A and the second bending part 22A are formed on the ground side of the tape terminal 20 by bending downward; the third bent portion 23A is formed by bending upward on the upper side of the tape terminal 20.
Because the structure of the material belt terminal 20 is slender, the height of the bending part is very high, when the terminal material belt is loaded by a reel, the stress point of the terminal material belt is the bending part, in order to avoid deformation in the packaging and carrying processes as much as possible, a protection supporting leg needs to be arranged to support the terminal material belt, and the bending part is overhead to protect the terminal functional area from being deformed by external force collision. The supporting portion of the conventional tape terminal 20 is bent to form a protection leg. Specifically, as shown in fig. 3, the first supporting portion 24 and the second supporting portion 25 are bent to form a first protection leg 24A and a second protection leg 25A, as shown in fig. 4, correspondingly, the first protection leg 24A and the second protection leg 25A are bent upward to form the upper side of the tape terminal 20, and the first protection leg 24A and the second protection leg 25A are higher than the third bent portion 23A to make the third bent portion 23A overhead; the third supporting portion 26 and the fourth supporting portion 27 as shown in fig. 3 are bent to form a third protection leg 26A and a fourth protection leg 27A as shown in fig. 4, the third protection leg 26A and the fourth protection leg 27A are bent downward to be formed on the ground side of the tape terminal 20, and the third protection leg 26A and the fourth protection leg 27A are higher than the first bent portion 21A and the second bent portion 22A to make the first bent portion 21A and the second bent portion 22A overhead. However, since the material thickness of the material strip terminal 20 is very thin, the strength of the material strip terminal 20 is very weak, and a deformation phenomenon still exists in the production process, which seriously affects the subsequent embedded injection molding automation operation of the material strip terminal and even causes the damage of parts of an injection molding mold.
Meanwhile, as the plurality of protection support legs are additionally arranged on the material belt terminal 20, when the terminal material belt is packaged and received, the winding number of the terminal material belt in each reel is very small due to too high layer height, the reel switching frequency in the processes of stamping, blanking, bending, forming, electroplating and embedding in the injection molding is increased, the material changing working hours are increased, the loss of the tail material of the head of each reel of the terminal material belt is caused, and the production cost is increased.

Referring to fig. 5 to fig. 14, a tape terminal stamping system according to the present invention is described, which includes a tape terminal stamping process and a tape terminal stamping mechanism.
The material strip terminal stamping and forming mechanism comprises a terminal stamping device 100, a terminal electroplating device, a terminal bending and forming device 200 and an injection molding mold which are sequentially formed.
Referring to fig. 9 and 10, a terminal stamping apparatus 100 of the present invention includes a sheet metal material feeding end 110, a full-flat stamping die 120, and a full-flat terminal discharging end 130.
The all-flat stamping die 120 stamps the sheet metal material fed from the sheet metal material feed end 110 to stamp the sheet metal material into an all-flat terminal strip of all-flat terminals 300 that is output by the all-flat terminal discharge end 130 to the terminal plating apparatus.
Specifically, the full-plane stamping die 120 includes a full-plane stamping upper die 120A and a full-plane stamping lower die 120B, a full-plane stamping punch 122 is arranged on a full-plane stamping upper die holder 121 of the full-plane stamping upper die 120A, a full-plane stamping die 124 is arranged on a full-plane stamping lower die holder 123 of the full-plane stamping lower die 120B, and shapes of the full-plane stamping punch 122 and the full-plane stamping die 124 are machined according to different shapes of the full-plane terminal 300. The all-plane punch 122 and the all-plane punch die 124 are matched with each other to punch a metal sheet material, so that the metal sheet material forms an all-plane terminal strip composed of all-plane terminals 300.
The first production step of the stamping forming process of the material strip terminal is to stamp the metal sheet material fed from the metal sheet material feeding end 110 by the full-plane stamping die 120 to form the full-plane terminal material strip. As shown in fig. 5 and 6, the tape terminal on the all-plane terminal tape is an all-plane terminal 300. The all-plane terminal material belt consisting of the all-plane terminals 300 can avoid the deformation problem of each material belt terminal on the all-plane terminal material belt, thereby ensuring the smooth proceeding of the subsequent production operation, guaranteeing the quality and improving the productivity. When the all-plane terminal material belt is used for packaging and receiving materials, the layer height of the all-plane terminal material belt is only the thickness of the metal sheet material, the number of rolled products on each reel can be greatly increased (from 5000 to 25000 per reel), the reel switching frequency of stamping, electroplating and injection molding is reduced, and the production efficiency is improved; meanwhile, the consumption and the handling cost of the packaging material are reduced; and the loss ratio of the head and tail of each roll of the full-plane terminal material is reduced.
In the second step of the stamping process of the material strip terminal, the all-plane terminal material strip consisting of the all-plane terminals 300 is electroplated by the terminal electroplating device. As shown in fig. 5 and 6, the full-plane terminal 300 of the present invention is provided with one or more plating portions, and the terminal plating apparatus performs a plating operation on the one or more plating portions provided on the plane terminal 300. In this embodiment, the all-plane terminal 300 is provided with a first plating portion 310, a second plating portion 320 and a third plating portion 330.
The third step of the material strip terminal stamping forming process of the present invention is to bend the all-plane terminal 300 on the all-plane terminal material strip by the terminal bending forming device 200 to bend the all-plane terminal 300 into the material strip terminal 300A with the required shape. Referring to fig. 7, the one or more electroplated parts are bent by the bending forming device 200 to form one or more bending parts.
Referring to fig. 11 and 12, the terminal bending and forming device 200 of the present invention is used to bend the all-plane terminal 300 in place and pull the material inside the mold. The terminal bending and forming device 200 includes a full-plane terminal feeding end 210, a bending and forming die 220, a material pulling mechanism 230, and a bending and forming terminal discharging end 240, which are sequentially formed.
The all-plane terminal material belt electroplated by the terminal electroplating device is fed to the bending forming die 220 from the all-plane terminal feeding end 210, the bending forming die 220 bends the all-plane terminal 300 in the all-plane terminal material belt into the material belt terminal 300A with the required shape, and the material belt terminal 300A with the required shape forms the bent terminal material belt. The bent terminal material strap is pulled by the pulling mechanism 230 to be discharged from the bent terminal discharging end 240.
Specifically, the bending forming die 220 includes an upper bending forming die 220A and a lower bending forming die 220B, the upper bending forming die 220A is provided with a bending punch 221, the lower bending forming die 220B is provided with a bending die 222, and the shapes of the bending punch 221 and the bending die 222 are changed according to the different shapes of the material belt terminal 300A with the required shape. The bending punch 221 and the bending die 222 are matched with each other to bend the all-plane terminal 300 in the all-plane terminal material strip, so that the all-plane terminal material strip forms the bent terminal material strip formed by the material strip terminals 300A in the required shape.
The all-plane terminal 300 after the electroplating operation is fed from the all-plane terminal feeding end 210 and is bent into the material strip terminal 300A with the required shape by the bending forming die 220, so that the all-plane terminal material strip is processed into the bent terminal material strip consisting of the material strip terminal 300A with the required shape. Specifically, the bending mold 220 bends the plating portion and the supporting portion of the all-plane terminal 300 to form the material strip terminal 300A having the bending portion and the protection leg thereon.
Specifically, the plated portion provided on the all-plane terminal 300 is bent by the bending mold 220 of the present invention to form a bent portion, the bent portion is formed on the top side and the bottom side of the all-plane terminal 300, and the bent portion provided on the top side of the all-plane terminal 300 is higher than the bent portion provided on the bottom side of the all-plane terminal 300.
The supporting portion provided on the all-plane terminal 300 is bent by the inventive bending forming mold 220 to form a protection leg, the protection leg is formed on the ground side of the all-plane terminal 300, and the protection leg is higher than the bending portion provided on the ground side of the all-plane terminal 300.
In this embodiment, the fully planar terminal 300 after the plating operation is completed is provided with the first plated portion 310, the second plated portion 320 and the third plated portion 330 as shown in fig. 5, and after the bending by the bending mold 220 of the invention, the first plated portion 310, the second plated portion 320 and the third plated portion 330 are correspondingly formed into the first bent portion 310A, the second bent portion 320A and the third bent portion 330A as shown in fig. 7. The first bent portion 310A and the second bent portion 320A are bent downward and formed on the ground side of the all-plane terminal 300; the third bent portion 330A is bent upward and formed on the upper side of the all-plane terminal 300; and the height of the third bending part 330A is greater than the height of the first bending part 310A and the second bending part 320A.
The full-flat terminal 300 after the plating operation is completed is provided with a first supporting part 340 and a second supporting part 350 as shown in fig. 5, and after the first supporting part 340 and the second supporting part 350 are bent by the inventive bending forming mold 220, a first protection leg 340A and a second protection leg 350A as shown in fig. 7 are correspondingly formed. The first protection leg 340A and the second protection leg 350A are bent downward to be formed on the ground side of the all-plane terminal 300, and the first protection leg 340A and the second protection leg 350A are higher than the first bent portion 310A and the second bent portion 320A to make the first bent portion 310A and the second bent portion 320A overhead.
Because the bending forming mold 220 is arranged at the front end of the injection molding mold, the all-plane terminal 300 after the electroplating operation comes out of the bending forming mold 220 and then enters the injection molding mold immediately, the third bending part 330A is formed on the day side of the all-plane terminal 300 by bending upwards, the day side of the all-plane terminal 300 is free from external force and deformation, and therefore a protection supporting leg does not need to be arranged. Eliminating the need to provide a higher protective foot on the top side of the all-flat terminal 300 increases the overall strength of the desired shape strip terminal 300A. On the contrary, the first bent portion 310A and the second bent portion 320A are bent downward to be formed at the ground side of the all-plane terminal 300, or the first protection leg 340A and the second protection leg 350A need to be provided, so that the first bent portion 310A and the second bent portion 320A need to be supported in an overhead manner, and the first bent portion 310A and the second bent portion 320A are prevented from being deformed by an external force.
The ground side of the all-plane terminal 300 needs to be provided with a protection leg, and the higher the protection leg, the poorer the strength, therefore, further, the height of the first protection leg 340A and the second protection leg 350A should be lower than the height of the third bending portion 330A, so as to further enhance the overall strength of the tape terminal 300A with the desired shape.
The bent terminal material tape of the invention is automatically moved to the bent terminal discharge end 240 through the material pulling mechanism 230.
Specifically, as shown in fig. 13 and 14, the drawing mechanism 230 of the present invention includes a feeding die 231, a feeding punch 232, and a spring device 233. The spring device 233 is connected with the feeding female die 232 to move the feeding female die 232 linearly back and forth; the feeding female die 232 is arranged corresponding to the bent terminal material belt so as to synchronously drive the bent terminal material belt; the feeding punch 232 abuts against the feeding die 231 to push the feeding die 231 to move towards the direction of the bending terminal discharging end 240.
When the feeding punch 232 does not move downward to push the feeding die 231, the feeding die 231 is at a feeding initial point (the feeding die 231 moves leftward as shown in fig. 13) under the elastic force of the spring device 233, and the feeding die 231 does not contact and abut on the bent terminal material belt.
When the feeding punch 232 moves downwards and pushes the feeding die 231, the feeding die 232 contacts and abuts against the bent terminal material belt (the feeding die 232 is in a closed state), and the feeding die 232 overcomes the elastic force of the spring device 233 and synchronously drives the bent terminal material belt to move towards the direction of the bent terminal discharging end 240 (the feeding die 232 moves towards the right direction as shown in fig. 14). The bent terminal discharge end 240 outputs the bent terminal material strap to the injection mold.
Further, in order to realize the automatic and stable material pulling function of bending the terminal material belt, the contact surface of the feeding punch 232 and the feeding die 231 which are abutted against each other is an inclined surface, and the inclined surface comprises a punch inclined surface 232A arranged on the feeding punch 232 and a die inclined surface 231A arranged on the feeding die 231. When the punch press drives the feeding punch 232 to move downwards, the feeding female die 231 performs closing action, and the feeding female die 231 overcomes the elasticity (compression spring) of the spring device 233 and synchronously pulls the bending terminal material strip to move under the action of inclined insertion of the punch inclined surface 232A of the feeding punch 232.
The fourth step of the material strap terminal stamping forming process is that the bent terminal material strap discharged from the bent terminal discharging end 240 does not need to be packaged again, the bent terminal material strap is directly sent to an injection molding mold from the bent terminal discharging end 240, and the injection molding mold directly enters injection molding operation for the material strap terminal 300A in the required shape on the bent terminal material strap without interference.
