Technical Field
[0001] The utility model relates to the technical field of wire harness terminal forming, in particular to a multi-wire harness terminal stamping and forming device. Background Art
[0002] A wire harness terminal is a fitting product used to achieve electrical connection. With the increasing automation of new energy vehicles, the usage of wire harness segments is gradually increasing; the electrical system of automobiles is also becoming increasingly powerful, and various electrical appliances with different characteristics are emerging continuously, and their requirements for the electrical performance of wire harnesses are also getting higher and higher. Wire harness terminals play an extremely important role in wire harnesses and the entire electrical system. A multi-wire harness terminal is to fix multiple wire harnesses in a terminal through stamping, which can improve the convenience of using wire harnesses.
[0003] In the prior art, a stamping and forming device is mostly used to process wire harness terminals, which mostly includes a base, a stamping cylinder, and a stamping block. The base is provided with a column, the stamping cylinder is arranged on the column, and the stamping block is arranged on the piston rod of the stamping cylinder. During stamping, after inserting multiple wire harnesses into the terminal, place them under the stamping block, and start the stamping cylinder to push the stamping block to press the terminal. Then, fix multiple wire harnesses in a terminal through pressing the terminal to complete the processing.
[0004] However, in the actual processing process, in order to improve efficiency, multiple multi-wire harness terminals are mostly stamped together to save time. However, during stamping, adjacent terminals may be close to each other, and the terminals are squeezed against each other during stamping, resulting in strange and inconsistent shapes after stamping, which is not convenient for subsequent sorting, storage, and use. Summary of the Utility Model
[0005] In order to improve the consistency of the shape of the terminal after stamping and forming, and to facilitate subsequent sorting, storage, and use, the present application provides a multi-wire harness terminal stamping and forming device.
[0006] A multi-wire harness terminal stamping and forming device provided by the present application adopts the following technical solutions:
[0007] A multi-wire harness terminal stamping and forming device includes a base and a column. The column is provided with a stamping cylinder, the stamping cylinder is provided with an upper stamping block, the upper stamping block is provided with a plurality of stamping teeth, the base is provided with a lower stamping block, the lower stamping block is arranged directly below the upper stamping block, and the lower stamping block is provided with a plurality of stamping tooth grooves for the stamping teeth to insert into.
[0008] By adopting the above technical solution, during terminal processing, after inserting multiple wire harnesses into the terminal, the terminal is inserted into the stamping tooth grooves on the lower stamping block. Then, the stamping cylinder is started to drive the upper stamping block to press down, so that the stamping tooth block is inserted into the stamping tooth groove for stamping. Multiple terminals can be stamped simultaneously through multiple stamping tooth blocks and stamping tooth grooves. At the same time, each terminal is independently inserted into the stamping tooth groove, and there will be no mutual extrusion interference during stamping. The shape of the terminal after stamping is related to the shapes of the stamping tooth groove and the stamping tooth block. Since it is not interfered by other terminals, the shapes of the stamped terminals are basically the same, which is convenient for subsequent sorting and storage, and also convenient for inserting into the corresponding slot holes or entering a specific space for use.
[0009] Preferably, the base is provided with a fixing block and fixing bolts. The fixing bolts are used to fix the fixing block on the base, and the lower stamping block is arranged on the fixing block.
[0010] By adopting the above technical solution, the lower stamping block is connected to the fixing block, and the fixing block is fixed on the base through the fixing bolts. During the stamping process, certain wear will inevitably occur on the inner wall of the stamping tooth groove of the lower stamping block. During long-term use, the wear degrees of each stamping tooth groove are different, which will cause the terminals formed by stamping to have different shapes due to the wear of the stamping tooth groove, which is not conducive to sorting, storage and use. Therefore, it is necessary to regularly check the wear condition. When relatively serious wear occurs, the fixing block is removed and installed through the fixing bolts, so as to replace the lower stamping block for maintenance.
[0011] Preferably, the base is provided with a fixing groove, and the lower stamping block is inserted into the fixing groove.
[0012] By adopting the above technical solution, the lower stamping block is inserted into the fixing groove of the base, which improves the connection stability between the base and the lower stamping block. At the same time, during stamping, the bottom wall of the fixing groove abuts against the lower stamping block, so as to share part of the pressure borne by the lower stamping block, reduce the possibility of fracture at the connection between the lower stamping block and the fixing block, and improve the overall durability.
[0013] Preferably, the lower stamping block is provided with a protective plate, and the protective plate is provided with stamping holes communicated with the stamping tooth grooves.
[0014] By adopting the above technical solution, when stamping, it is necessary to manually hold the wire harness inserted with the terminal to prevent the wire harness from driving the terminal to move, so that the terminal moves obliquely during stamping and is stamped into a distorted shape, and at the same time reduce the possibility that the terminal is obliquely pressed against the stamping tooth block to damage the wire harness. However, when manually holding the wire harness, there is a situation where the hand is too close to the stamping tooth block and is bruised, and the safety risk is relatively high. Therefore, a protective plate is provided. During stamping, the terminal and the wire harness are inserted into the stamping tooth groove after passing through the stamping holes, and the hand is placed on the side of the protective plate away from the lower stamping block for support, reducing the risk of bruising and improving the safety performance.
[0015] Preferably, the lower stamping block is provided with a mounting groove, and the protective plate is inserted into the mounting groove.
[0016] By adopting the above technical solution, the protective plate is inserted into the mounting groove, improving the stability of the connection and fixation between the lower stamping block and the protective plate.
[0017] Preferably, the lower stamping block is provided with mounting bolts for mounting the protective plate on the lower stamping block.
[0018] By adopting the above technical solution, the protective plate is mounted on the lower stamping block through the mounting bolts. When the protective plate is damaged, it can be replaced in time, improving the convenience of replacing the protective plate.
[0019] Preferably, the piston rod of the stamping cylinder is provided with a connecting block, and the connecting block is provided with connecting bolts for connecting the upper stamping block to the connecting block.
[0020] By adopting the above technical solution, the stamping teeth on the upper stamping block may be worn after long-term use and need to be replaced to ensure that the shape of the terminal after stamping is consistent with the set shape. When the stamping teeth are worn, the upper stamping block can be removed and replaced through the connecting bolts.
[0021] Preferably, the connecting block is provided with a connecting groove, and the upper stamping block is inserted into the connecting groove.
[0022] By adopting the above technical solution, the upper stamping block is inserted into the connecting groove, improving the stability of the connection between the upper stamping block and the connecting block. When stamping, the inner wall of the connecting groove abuts against the upper stamping block, sharing the pressure borne by the upper stamping block and reducing the possibility of damage to the connection between the upper stamping block and the connecting block, improving durability.
[0023] In summary, the present application includes at least one of the following beneficial technical effects:
[0024] 1. By providing a base, a column, a stamping cylinder, an upper stamping block, stamping teeth, a lower stamping block and stamping tooth grooves, after inserting the wire harness into the terminal, the terminal is inserted into the stamping tooth grooves on the lower stamping block, and the stamping cylinder on the base column is started to drive the upper stamping block to press down, so that the stamping teeth are inserted into the stamping tooth grooves to stamp the terminal. Multiple groups of terminals can be stamped simultaneously, and each terminal is independently inserted into a stamping tooth groove, and they do not affect each other during stamping, so that the stamping forming is not interfered, maintaining the consistency of stamping forming, which is convenient for subsequent sorting, storage and use;
[0025] 2. By setting a protective plate, stamping holes, mounting grooves and mounting bolts, the protective plate is inserted into the mounting groove of the lower stamping block and mounted on the lower stamping block through the mounting bolts. During use, the terminal and the wire harness are passed through the stamping holes on the protective plate and inserted into the stamping tooth grooves for stamping. During the stamping process, the wire harness is held by hand, so as to ensure the stability of the terminal during stamping. The protective plate blocks the lower stamping block and the hand, reducing the possibility of the hand being crushed and improving the safety performance;
[0026] 3. By setting a fixing block, fixing bolts and fixing grooves, the lower stamping block is inserted into the fixing groove of the base, and at the same time the fixing block is connected to the lower stamping block and mounted on the base through the fixing bolts. When the stamping tooth grooves of the lower stamping block are severely worn, the fixing block can be disassembled through the fixing bolts for replacement, which is simple and convenient.
