Description

Technical Field

[0001] This utility model relates to the field of terminal machine mold technology, and in particular to an electronic terminal mold with an elastic pre-compression mechanism. Background Technology

[0002] It can precisely fix the terminals before crimping, avoiding terminal displacement or deformation caused by poor rigidity or substrate arching. At the same time, it reduces the possibility of terminals tilting due to sudden pressure by buffering elasticity, greatly improving crimping accuracy and stability. It is especially suitable for terminals with small size, high precision requirements, high strength, or large crimping force. Its pre-pressing function is integrated with the mold, which can automatically complete the terminal crimping, eliminating manual operation and improving production efficiency. It can also reduce abnormal contact friction with the mold due to pre-positioning of the terminals, reducing mold wear.

[0003] First, the elastic pre-compression module, which includes springs, pre-compression pins, and plate components, is precisely assembled with the mold forming station. By replacing the elastic components or adjusting the screws, the compression stroke and initial elastic force are preset according to the terminal thickness and material. Then, the mold is installed into a precision servo-driven pneumatic crimping machine. The equipment control system links the feeding mechanism to first trigger the pre-compression mechanism to fix the terminal in the slot, preventing displacement or deformation. Subsequently, the crimping machine performs the crimping action. During the process, the elastic pre-compression structure can also buffer the pressure and reduce abnormal friction of the mold, ensuring that it can adapt to the production needs of different types of terminals and taking into account both crimping accuracy and efficiency.

[0004] When manually placed, there may be a slight gap between the terminal and the positioning reference surface of the mold, and the edge of the terminal may not be in contact with the positioning pin of the station. Moreover, the direction and magnitude of the deviation of each terminal are not fixed. To solve the above problems, an electronic terminal mold with an elastic pre-compression mechanism is proposed. Utility Model Content

[0005] To overcome the above deficiencies, this utility model provides an electronic terminal mold with an elastic pre-compression mechanism, which aims to solve the problem in the prior art that there may be a small gap between the terminal and the mold positioning reference surface, and the terminal edge may not be in contact with the positioning pin of the work station.

[0006] To achieve the above objectives, this utility model adopts the following technical solution: an electronic terminal mold with an elastic pre-compression mechanism, comprising a mold body, an electric telescopic rod fixedly connected to the inner wall of the mold body, an upper cutter fixedly connected to the outer wall of the electric telescopic rod, a fixing block fixedly connected to the outer wall of the upper cutter, a sliding groove formed in the inner wall of the fixing block, a slider slidably connected to the inner wall of the sliding groove, a bidirectional threaded rod threadedly connected to the inner wall of the slider via a threaded sleeve, a hinge rod rotatably connected to the inner wall of the slider, an extrusion plate fixedly connected to the outer wall of the hinge rod, and a groove formed in the inner wall of the mold body, the groove being elastically connected to the outer wall of the extrusion plate via a spring.

[0011] As a further description of the above technical solution:

[0012] An elastic buffer pad is fixedly connected to the outer wall of the extrusion plate, and the elastic buffer pad is made of rubber.

[0013] As a further description of the above technical solution:

[0014] The number of fixed blocks is five groups, and each group has two fixed blocks.

[0015] As a further description of the above technical solution:

[0016] The outer wall of the threaded sleeve is fixedly connected to the inner wall of the fixed block, and the inner wall of the threaded sleeve is threadedly connected to the outer wall of the bidirectional threaded rod.

[0019] As a further description of the above technical solution:

[0020] The outer wall of the slider is in close contact with the inner wall of the groove.

[0021] This utility model has the following beneficial effects:

[0022] 1. Through the synergistic action of the spring and the extrusion plate, the terminal is precisely pre-fixed. When the fixing block moves down with the upper cutter, the extrusion plate first contacts the terminal and forms a stable pre-pressure through spring compression. This pre-pressure can tightly fit the terminal to the designated position on the mold body, eliminating the small gaps and positional deviations when the terminal is initially placed.

[0023] 2. In this utility model, the bidirectional threaded rod driven adjustment system can be steplessly adjusted to adapt to the external dimensions of various terminals for processing different types of terminals. There is no need to replace the special clamping parts. Moreover, the spring preload state can be optimized simultaneously when adjusting the spacing, providing a stable elastic clamping force for terminals with different precision requirements, avoiding processing errors, and significantly shortening the switching time for processing multiple models, reducing the investment in special parts, and combining adaptability flexibility, processing reliability and production economy.

[0030] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0031] Reference Figures 1-3The present invention provides an embodiment of an electronic terminal mold with an elastic pre-compression mechanism, comprising a mold body 1, an electric lifting rod 2 fixedly connected to the inner wall of the mold body 1, the electric lifting rod 2 serving as the power actuator of the mold, capable of precise lifting and retraction according to processing requirements, providing a power source for the movement of the upper cutter 3, the upper cutter 3 fixedly connected to the outer wall of the electric lifting rod 2, the lifting and retraction of the electric lifting rod 2 directly driving the upper cutter 3 to move up and down, a fixing block 4 fixedly connected to the outer wall of the upper cutter 3, the fixing block 4 mainly serving a connecting and supporting function, a groove 8 opened in the inner wall of the fixing block 4 to provide a sliding track for the slider 9, restricting the movement direction of the slider 9, ensuring that the slider 9 can only slide smoothly along the preset trajectory of the groove 8, avoiding deviation of the slider 9 during movement, affecting the pre-compression effect, the slider 9 slidably connected to the inner wall of the groove 8, the slider 9 being able to slide freely within the groove 8, while the groove 8 serving as a guide and limiting function for the slider 9, the inner wall of the slider 9 being open A threaded sleeve 6 is threadedly connected to a bidirectional threaded rod 5. The threaded sleeve 6 is fixedly installed on the inner wall of the slider 9. The external thread of the bidirectional threaded rod 5 meshes with the internal thread of the threaded sleeve 6. When the bidirectional threaded rod 5 rotates, it drives the slider 9 to move in the slide groove 8 through the threaded transmission. A hinge rod 12 is rotatably connected to the inner wall of the slider 9. The hinge rod 12 mainly plays the role of force transmission, converting the linear motion of the slider 9 into the pre-pressing action of the extrusion plate 13. It is a key transmission component connecting the slider 9 and the extrusion plate 13. The extrusion plate 13 is fixedly connected to the outer wall of the hinge rod 12. The extrusion action of the extrusion plate 13 realizes the pre-pressing and fixing of the terminal, ensuring the stability of the terminal position during processing and improving processing accuracy. A groove 7 is opened on the inner wall of the mold body 1. The size of the groove 7 matches the installation requirements of the extrusion plate 13. The groove 7 is elastically connected to the outer wall of the extrusion plate 13 through a spring 11. When the extrusion plate 13 is subjected to external force, the spring 11 will be compressed to realize the elastic pre-pressing of the terminal.

[0032] Reference Figures 2-4 One end of the spring 11 is fixedly connected to the inner wall of the groove 7, and the spring 11 and the inner wall of the groove 7 are stably fixedly connected. This connection method can ensure that the spring 11 will not be displaced when it is compressed under force. The other end of the spring 11 is fixedly connected to the outer wall of the extrusion plate 13, and the spring 11 and the outer wall of the extrusion plate 13 are tightly connected to provide elastic support for the extrusion plate 13. A knob 10 is fixedly connected to the outer wall of the bidirectional threaded rod 5. The knob 10 makes it convenient for the operator to manually rotate the bidirectional threaded rod 5. An elastic buffer pad 14 is fixedly connected to the outer wall of the extrusion plate 13. The elastic buffer pad 14 can reduce the hard impact on the terminal during extrusion. The elastic buffer pad 14 is made of rubber material. Rubber material has good elasticity, wear resistance and insulation, and can fully play the role of buffer protection.

[0033] Reference Figures 2-4There are five sets of fixed blocks 4, with two fixed blocks 4 in each set. This number and layout can ensure the overall structure is stress-balanced. The outer wall of the threaded sleeve 6 is fixedly connected to the inner wall of the fixed block 4. The inner wall of the threaded sleeve 6 is threadedly connected to the outer wall of the bidirectional threaded rod 5. The threaded connection enables the movable connection between the threaded sleeve 6 and the bidirectional threaded rod 5. The shape of the groove 7 is adapted to the shape of the extrusion plate 13. The outer wall of the slider 9 is tightly fitted to the inner wall of the slide groove 8. The inner walls of the slider 9 and the slide groove 8 are tightly fitted with a very small gap, which can effectively prevent the slider 9 from jamming or shaking when sliding.

[0034] Working principle: The operator precisely places the electronic terminal to be processed on the workstation of the mold body 1 to ensure that the terminal will not shift significantly during subsequent processing. The electric lifting rod 2 is activated and raised downwards. Its output end is rigidly connected to the upper cutter 3, driving the upper cutter 3 to move downwards synchronously. At the same time, the fixing block 4 is fixedly connected to the upper cutter 3 and descends with the upper cutter 3. As the fixing block 4 moves downwards, the extrusion plate 13 connected to its bottom gradually approaches the terminal until it is in complete contact with the terminal surface. At this time, the electric lifting rod 2 continues to move downwards. Since the extrusion plate 13 is blocked by the terminal, it can no longer move downwards. The fixing block 4 and the extrusion plate... Spring 11 between 13 begins to be compressed. During the compression process, spring 11 undergoes elastic deformation, and its deformation force is converted into continuous preload. This preload is evenly transmitted to the terminal surface through the extrusion plate 13, ensuring that the terminal is tightly clamped and subjected to balanced force, thus preventing local loosening. The rubber elastic buffer pad 14 wrapped around the outside of the extrusion plate 13 plays a dual role. It absorbs the impact at the moment of contact between the extrusion plate 13 and the terminal, preventing hard contact from causing damage to the plating or structural deformation of the terminal surface. By utilizing the high coefficient of friction of the rubber material, the friction between the extrusion plate 13 and the terminal is enhanced, effectively preventing the terminal from slipping due to force during processing.

[0035] When the compression of spring 11 reaches the set value, that is, when the pre-pressure meets the processing stability requirements, the electric lifting rod 2 continues to rise downward, driving the upper cutter 3 to break through the pre-pressure stroke and move further downward. At this time, spring 11 is still in a compressed state, continuously providing a stable clamping and positioning force for the terminal, ensuring that the terminal will not be displaced or vibrated when the upper cutter 3 performs cutting and stamping operations, ensuring that the processing accuracy meets the technical requirements. After the processing is completed, the electric lifting rod 2 begins to retract, driving the upper cutter 3 and the fixed block 4 to move upward synchronously. As the fixed block 4 moves upward, the pressure on spring 11 is gradually released, returning to a natural relaxed state. The extrusion plate 13 disengages from the terminal under the elastic force of spring 11. Finally, the electric lifting rod 2 retracts completely, and all parts of the mold return to their initial positions, waiting for the start of the next processing cycle.

[0036] When the processing terminal model is changed or the processing accuracy requirements are adjusted, the initial spacing of the extrusion plate 13 needs to be changed through the spacing adjustment system to adapt to the clamping requirements under the new working conditions. The operator triggers the adjustment action by turning the knob 10. The knob 10 is fixedly connected to one end of the bidirectional threaded rod 5, causing the bidirectional threaded rod 5 to rotate around its own axis. The bidirectional threaded rod 5 is connected to the inner wall of the fixed block 4 through the bearing assembly. The bidirectional threaded rod 5 adopts a bidirectional thread design, with the threads at both ends having opposite directions of rotation, and forms a precision thread fit with the threaded sleeve 6 installed on the inner wall of the fixed block 4. The threaded sleeve 6 is rigidly connected to the slider 9, and the slider 9 is embedded in the groove 8 on the inner wall of the fixed block 4. The groove 8 guides and limits the slider 9, restricting it to move only in the horizontal direction. When the knob 10 is turned clockwise, the bidirectional threaded rod 5 rotates around its own axis. When the threaded rod 5 rotates clockwise, the sliders 9 at both ends move synchronously towards the center along the slide groove 8 under the action of the threaded engagement. When the knob 10 is turned counterclockwise, the bidirectional threaded rod 5 rotates counterclockwise, and the sliders 9 at both ends move synchronously to both sides along the slide groove 8. The extrusion plate 13 is connected to the slider 9 through a connecting rod structure. The movement of the slider 9 directly drives the extrusion plate 13 to move synchronously, thereby changing the initial distance between the two extrusion plates 13 to adapt to the external dimensions of the new specification terminal. At the same time, the adjustment of the position of the extrusion plate 13 will change the initial compression state of the spring 11, so that the preload stroke and elastic force output range of the spring 11 are adjusted accordingly, ensuring that a stable elastic clamping force that meets the processing accuracy requirements can still be provided for the terminal under the new working conditions, avoiding clamping failure or processing errors due to changes in terminal specifications.
