Description

Technical Field

[0001] This utility model belongs to the field of cable pressing technology, specifically a small cable pressing device. Background Technology

[0002] With the continuous development of the manufacturing industry, the requirements for cable crimping equipment are also increasing. Traditional cable crimping equipment mostly adopts manual or semi-automatic operation, which is difficult to meet the high efficiency requirements of large-scale production, and also has certain quality stability issues. Because these devices rely on manual adjustment and operation, the differences in the technical level and experience of different operators will directly affect the crimping quality, and traditional equipment performs poorly in the crimping adaptability of multiple specifications of cables. Currently, most cable crimping equipment on the market has the following problems:

[0003] 1. Complex structure and difficult maintenance: The complex structure of traditional cable crimping equipment not only increases production costs, but also makes daily maintenance cumbersome and the equipment failure rate high. Users need to frequently stop the machine for maintenance, resulting in excessive downtime and reduced production efficiency. This disadvantage is particularly prominent for small-batch or multi-variety production.

[0004] 2. High cost and unsatisfactory cost-effectiveness: Although high-end cable crimping equipment has improved in some aspects, its complex mechanical design and high manufacturing cost limit its popularity among small and medium-sized enterprises; while low-cost equipment usually fails to meet expectations in crimping accuracy and consistency, resulting in many performance bottlenecks in actual production.

[0005] 3. Unstable crimping performance: Some existing equipment does not control the crimping force accurately during use, which can easily cause unstable crimping. Overly tight crimping may damage the conductivity of the cable, while overly loose crimping will result in an insecure connection, thus affecting the reliability of the entire cable connection.

[0006] 4. Poor adaptability and insufficient flexibility: Existing equipment usually performs well in crimping single-specification cables, but its adaptability is poor when crimping multiple different specifications and types of cables is required; frequent mold changes or equipment readjustments are not only time-consuming, but may also affect production continuity and reduce overall production efficiency.

[0007] To address these shortcomings, this patent proposes a small cable crimping device that features low maintenance costs, strong crimping stability, and wide adaptability. Utility Model Content

[0035] Example, refer to Figures 1 to 4 A small cable pressing device includes a cable plug conforming fixing slide 1, a fixing base 2, and a push-pull slide 6;

[0036] The cable plug contouring fixed slide 1 is set on the upper surface of the fixed base 2, and the push-pull slide 6 is movably connected to the surface of the fixed base 2. A connecting seat 9 is installed at the center of the back of the fixed base 2, and a push-pull cylinder 8 is connected to the side of the connecting seat 9. The output end of the push-pull cylinder 8 extends into the connecting seat 9 and connects with the push-pull slide 6.

[0037] Reference Figure 1 , 23. A second clamping cylinder fixing plate 5 is installed on the side of the push-pull slide 6. A first clamping cylinder fixing plate 4 is installed on the top side of the second clamping cylinder fixing plate 5. The first clamping cylinder fixing plate 4 is located above the push-pull slide 6. A clamping cylinder 3 is installed on the side of the first clamping cylinder fixing plate 4. A lower pressure plate 11 is provided at the output end of the clamping cylinder 3. An upper pressure plate 12 is installed at the edge of the upper surface of the push-pull slide 6.

[0038] Reference Figure 1 and 4 The back edge of the fixed base 2 is equipped with a clamping cylinder solenoid valve 7 and a push-pull cylinder solenoid valve 10.

[0039] The pressing cylinder 3 presses down, and the lower pressing plate 11 and the upper pressing plate 12 press the cable. The push-pull cylinder 8 controls the push-pull slide 6 to pull back, giving the cable a tension force to verify the mechanical properties and ensure the quality of the pressing.

[0040] Working principle of clamping cylinder 3: Clamping cylinder 3 relies on the precise control of clamping cylinder solenoid valve 7. Its function is to realize the extension and retraction of the piston rod of clamping cylinder 3, thereby completing the clamping and releasing process. Clamping cylinder solenoid valve 7, as the core control component of the entire system, is connected to the main air source. The compressed air provided by the main air source is delivered to the air inlet of clamping cylinder solenoid valve 7 through pipeline. Clamping cylinder solenoid valve 7 has two air outlets, which are connected to the two air ports (air inlet and air outlet) of clamping cylinder 3 respectively. By controlling the switching state of clamping cylinder solenoid valve 7, the flow direction of compressed air can be adjusted, thereby controlling the action of clamping cylinder 3. When clamping cylinder solenoid valve 7 switches to the air inlet position where clamping cylinder 3 is extended, compressed air... Compressed air is introduced into the inlet of the pressing cylinder 3 from one outlet of the pressing cylinder solenoid valve 7. At this time, the compressed air creates pressure in the cavity of the pressing cylinder 3, pushing the piston forward. The piston drives the piston rod to extend outward, completing the pressing action. Conversely, when the pressing cylinder solenoid valve 7 switches to another position, the compressed air that previously entered the pressing cylinder 3 is guided to another outlet and discharged to the atmosphere through the exhaust port. At the same time, the pressing cylinder solenoid valve 7 changes the airflow direction, allowing the inlet of the pressing cylinder 3 to receive new air. Due to the reverse airflow, the pressure in the pressing cylinder 3 pushes the piston back to its original position, and the piston rod retracts, realizing the releasing action. In this way, the pressing cylinder 3 can return to its initial state, ready for the next operation.

[0041] Working principle of push-pull cylinder 8: The operation of push-pull cylinder 8 requires compressed air supplied by an air source as a power source; the push-pull cylinder solenoid valve 10, as the core control component, has its air inlet connected to the main air source; the main air source continuously supplies compressed air to the push-pull cylinder solenoid valve 10 through a pipeline to ensure sufficient air pressure in the entire system; when the push-pull cylinder solenoid valve 10 is in the air inlet position where the push-pull cylinder 8 is pushed out, compressed air enters one side cavity of the push-pull cylinder 8 through one air outlet of the push-pull cylinder solenoid valve 10; under the push of the compressed air, the piston inside the push-pull cylinder 8 is subjected to pressure and moves forward along the axis of the push-pull cylinder 8; at this time, the piston rod extends from the other end of the push-pull cylinder 8, applying a pushing force to the external load. This completes the "push" action. Simultaneously, the other cavity of the push-pull cylinder 8 is connected to the exhaust port of the push-pull cylinder solenoid valve 10, and the gas is discharged to the atmosphere through the exhaust port to avoid the formation of a reaction force in the cavity. When a "pull" action is required, the push-pull cylinder solenoid valve 10 switches to another position. At this time, the compressed air enters the other cavity of the push-pull cylinder 8 from the other exhaust port of the push-pull cylinder solenoid valve 10. The newly entered compressed air creates pressure in the push-pull cylinder 8, pushing the piston to move in the opposite direction and retracting the piston rod into the push-pull cylinder 8. At the same time, the cavity of the push-pull cylinder 8 that was originally filled with air is connected to the exhaust port to discharge excess gas. In this way, the piston rod can complete the "pull" action.

[0042] Figure 5The diagram shows the circuit diagram of this type of cable crimping equipment. This equipment is powered by an external power source, providing stable power support to the internal electrical and pneumatic systems. During operation, the external power source provides current to the coils of two key components—the pressing cylinder solenoid valve 7 and the push-pull cylinder solenoid valve 10—ensuring the normal operation of the entire system. When the system starts, current flows through the circuit to the coils of the pressing cylinder solenoid valve 7 and the push-pull cylinder solenoid valve 10. The energized coils generate electromagnetic force, causing the valve cores of the pressing cylinder solenoid valve 7 and the push-pull cylinder solenoid valve 10 to move. This movement of the valve core directly changes the internal air passages of the pressing cylinder solenoid valve 7 and the push-pull cylinder solenoid valve 10, determining the direction of compressed air flow. As the core control component of the pneumatic system, the pressing cylinder solenoid valve… The functions of solenoid valve 7 and solenoid valve 10 are crucial, as they independently control different pneumatic actuators or parts of the system's functions. The energization of solenoid valve 7 controls whether compressed air flows to a specific chamber of the corresponding pneumatic actuator. For example, when the coil of solenoid valve 7 is energized, the valve core switches to the corresponding position, and compressed air is guided into a certain chamber of solenoid valve 3, thereby pushing the piston to move and achieving a specific action. At the same time, the gas in the other chamber of solenoid valve 3 is discharged to the atmosphere through solenoid valve 7, avoiding the formation of a reaction force that hinders the piston's movement. Similarly, solenoid valve 10 works on the same principle as solenoid valve 7, but it controls the actions of another part of the pneumatic actuators in the system. By switching the energization of the solenoid valve 10 coil of the push-pull cylinder, the direction of compressed air flow is changed, thereby controlling the pressure in another set of chambers of the push-pull cylinder 8 and pushing the piston to move in the opposite direction. This bidirectional airflow control enables the system to achieve complex mechanical actions. The coordinated work of the two sets of solenoid valves, combined with the precise design of the circuit and air path, enables the entire device to efficiently complete the cable pressing operation. The state changes of the pressing cylinder solenoid valve 7 and the push-pull cylinder solenoid valve 10 can be switched at any time according to system requirements, realizing flexible control of the actions of different pneumatic components, ensuring both the synchronization and accuracy of the actions, and providing the reliability and repeatability of the operation.

[0043] See Figure 6 The diagram shows the pneumatic circuit of this type of cable pressing equipment. The equipment uses an external air source for air supply. When the pressing cylinder solenoid valve 7 and the push-pull cylinder solenoid valve 10 are energized, the valve core moves, and compressed air is guided into the pressing cylinder 3 and the push-pull cylinder 8, causing the pistons of the pressing cylinder 3 and the push-pull cylinder 8 to extend or retract forward. The speed control valve and the check valve control the speed and direction of the airflow to adjust the accuracy of the action of the pressing cylinder 3 and the push-pull cylinder 8. Through the coordinated work of the two cylinders, the equipment can complete the mechanical movement of fixing and pressing cables.

Such development efforts may be complex and time-consuming, but for those of ordinary skill in the art who benefit from this disclosure, the development effort will be a routine task in design, manufacturing, and production without requiring extensive experimentation.

Although this utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solution of this utility model without departing from the spirit and scope of the technical solution of this utility model, and all such modifications or substitutions should be covered within the scope of the claims of this utility model.
