Description

Technical Field

[0001] This utility model relates to the field of spring production technology, and in particular to a spring production and processing equipment. Background Technology

[0002] Springs, as a fundamental mechanical component, are widely used in various fields such as automobiles, aerospace, electronic equipment, and construction. Their main functions include absorbing energy through elastic deformation, damping shocks, and achieving automatic reset. The spring manufacturing process involves several key stages, including forming, heat treatment, surface treatment, grinding, and cleaning, each of which directly impacts the spring's performance, lifespan, and safety. Especially in the post-processing stage, immersion cleaning is a crucial step in removing surface oil, metal debris, and other impurities, significantly improving product quality and the reliability of subsequent processes. However, in practice, existing spring manufacturing equipment presents numerous inconveniences during immersion cleaning, severely impacting overall production efficiency and operational convenience.

[0003] Utility model patent CN220463235U discloses a spring production and processing equipment, including a workbench. A positioning box is fixedly connected to the upper surface of the workbench, and a positioning mechanism is installed inside the positioning box. Through the cooperation between a first protective cover, a second protective cover, a material trough, a chip trough, and a movable plate, and via a servo motor driving a threaded rod, two sets of movable blocks move relative to each other, thereby positioning the inner ring of the spring by the positioning rod. A cylinder drives the movable plate to move, and a grinding motor drives a grinding disc to grind the end of the spring. The first and second protective covers overlap, and the scrap iron chips generated during grinding splash into the inner side of the first and second protective covers and then enter the scrap iron chip collection box through the chip trough. This reduces the splashing of scrap iron chips during spring production, improves collection efficiency, reduces the workload of workers, and improves production efficiency. Although this equipment improves the automation and safety of the grinding process, there are still obvious defects in the subsequent immersion cleaning process.

[0004] Specifically, existing spring manufacturing equipment typically involves manually placing each spring into the cleaning solution during the cleaning process. This method is not only cumbersome and inefficient, but also lacks effective securing devices, leading to springs slipping and tipping over during cleaning. Furthermore, the lack of a standardized handling and positioning structure makes transferring springs between different workstations difficult, further increasing operational complexity and labor costs. Therefore, to address these shortcomings of existing technology, we urgently need an innovative spring manufacturing equipment to solve these problems. Utility Model Content

[0005] The purpose of this utility model is to provide a spring production and processing equipment, which solves the problem that in the existing spring production and processing equipment, the springs are generally placed into the cleaning solution one by one manually during the cleaning process. This is not only cumbersome and inefficient, but also lacks an effective fixing device, which makes the springs prone to slipping and tipping over during the cleaning process.

[0006] To achieve the above objectives, this utility model provides a spring production and processing equipment, including a frame, and a top frame fixedly connected to the top of the frame, and a bearing frame slidably connected to the inner side of the top frame;

[0007] The top of the support frame is provided with a top plate fixedly connected to the top frame. A hydraulic cylinder is fixedly connected to one side of the top of the top plate by bolts. The output shaft of the hydraulic cylinder passes through the top plate and is fixedly connected to the top of the support frame. A support rod is fixedly connected to one side of the inner side of the support frame. Support rods that are slidably connected to the inner wall of the support frame are provided on both sides of the support rod. A mounting frame is fixedly connected to one end of each support rod. Inner plates are detachably connected to the inner sides of the two mounting frames. A fixing frame is fixedly connected to the top of the support frame. A double-ended screw is rotatably connected to the inner side of the fixing frame. A drive motor is fixedly connected to one side of the outer wall of the fixing frame by bolts. One end of the double-ended screw passes through the fixing frame and is connected to the output shaft of the drive motor. Nut seats are threadedly connected to both ends of the double-ended screw. The bottom of the two nut seats is fixedly connected to the top of the two inner plates by bolts.

[0008] The support frame has sliding blocks fixedly connected to both sides, and all sliding blocks are slidably connected to the inner wall of the top frame through sliding grooves.

[0009] The bottom of each of the two nut seats is fixedly connected to a connecting rod, and the bottom of each connecting rod is fixedly connected to the top of each of the two inner plates by bolts. Each of the two mounting frames is provided with a threaded rod on one side, and the two threaded rods pass through the mounting frame and the inner plate in sequence through threaded grooves.

[0010] Each of the two nut seats has a slider fixedly connected to its top, and the slider is slidably connected to the top of the fixed frame through a groove.

[0011] One end of the bidirectional screw is rotatably connected to the inner wall of the fixed frame via a rotating shaft, and the other end of the bidirectional screw passes through the side wall of the fixed frame via a bearing sleeve. The outer side of the frame is rotatably connected to the door via a hinge, and a side groove is provided on one side of the top frame.

[0012] Each of the two support rods has a protrusion fixedly connected to one end, and the protrusion is slidably connected to the inner wall of the support frame through a movable groove.

[0013] This utility model discloses a spring production and processing equipment. Through the coordinated arrangement of a bearing rod and two support rods, it effectively provides multi-point support and fixation for the springs, solving the technical problem in existing technologies where the lack of an effective fixing device leads to springs easily slipping and tipping over during cleaning, thus improving operational stability and safety. Secondly, by driving a bidirectional screw to rotate via a drive motor, the two nut seats are controlled to move the support rods synchronously, thereby achieving automatic tightening and fixing of the springs. This not only simplifies the operation steps but also increases the automation level of the equipment, reduces manual intervention, and lowers labor intensity, meeting the needs of modern high-efficiency production. Thirdly, the hydraulic cylinder allows the bearing frame to smoothly lower the springs and immerse them in the cleaning fluid, avoiding the inefficiency caused by manually placing each spring one by one in the traditional method, significantly improving cleaning efficiency and meeting the actual needs of mass production. Furthermore, this structural design has good versatility and can adapt to spring cleaning operations of different sizes and specifications, enhancing the applicability of the equipment.

Detailed Implementation

[0021] The embodiments of the present invention are described in detail below. Examples of the embodiments are shown in the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain the present invention, but should not be construed as limiting the present invention.

[0022] Please see Figure 1-5 A spring manufacturing and processing equipment includes a frame 1, a top frame 3 fixedly connected to the top of the frame 1, and a bearing frame 6 slidably connected to the inner side of the top frame 3; the top of the bearing frame 6 is provided with a top plate 4 fixedly connected to the top frame 3, and a hydraulic cylinder 5 is fixedly connected to one side of the top of the top plate 4 by bolts, and the output shaft of the hydraulic cylinder 5 passes through the top plate 4 and is fixedly connected to the top of the bearing frame 6; a bearing rod 16 is fixedly connected to one side of the inner side of the bearing frame 6, and support rods 19 are provided on both sides of the bearing rod 16 and slidably connected to the inner wall of the bearing frame 6; and the two support rods 19... Each of the two mounting frames 20 is fixedly connected to one end. The inner sides of the two mounting frames 20 are detachably connected to the inner plates 23. The top of the bearing frame 6 is fixedly connected to the fixing frame 7. The inner side of the fixing frame 7 is rotatably connected to the bidirectional screw 8. The outer wall of the fixing frame 7 is fixedly connected to the drive motor 12 by bolts. One end of the bidirectional screw 8 passes through the fixing frame 7 and is connected to the output shaft of the drive motor 12. Both ends of the bidirectional screw 8 are connected to the nut seat 9 by threaded engagement. The bottom of the two nut seats 9 is fixedly connected to the top of the two inner plates 23 by bolts.

[0023] First, cleaning fluid is injected into the frame 1 as a medium for cleaning the springs. Then, the spring to be cleaned is fitted onto the support rod 16 and two support rods 19. The support rod 16 is located in the center of the inner coil of the spring, while the two support rods 19 are positioned on either side of the inner coil, providing auxiliary support and positioning. Next, the inner plate 23 is installed and fixed inside the mounting frame 20, and bolted to the bottom of the nut seat 9 to provide stable support for the support rods 19. Then, the drive motor 12 is started, driving the bidirectional screw 8 to rotate. Because the bidirectional screw 8 is connected to the two nut seats 9 by a threaded connection, ... When the bidirectional screw 8 rotates, the two nut seats 9 move in opposite directions inside the fixed frame 7, thereby driving the two support rods 19 to move outward synchronously, thus tightening and fixing the spring. Finally, the hydraulic cylinder 5 is activated, and its output shaft pushes the bearing frame 6 downward, causing the bearing frame 6 to slide along the top frame 3, and driving the bearing rod 16 and the fixed spring to move downward as a whole until the spring is completely immersed in the cleaning fluid in the frame 1, completing the entire cleaning process. During this process, the spring is stably fixed and supported, avoiding problems such as slippage and tipping that may occur in traditional manual operation, while realizing the simultaneous cleaning of multiple springs and improving cleaning efficiency.

[0024] Furthermore, sliding blocks 14 are fixedly connected to both sides of the support frame 6, and all sliding blocks 14 are slidably connected to the inner wall of the top frame 3 through sliding grooves 15. When the hydraulic cylinder 5 is activated, the support frame 6 can slide smoothly up and down along the top frame 3. This design ensures the stable movement of the spring during immersion in the cleaning fluid, avoiding spring position displacement caused by equipment vibration or improper operation, and improving the stability and safety of the cleaning process.

[0025] Furthermore, each of the two nut seats 9 has a connecting rod 21 fixedly connected to its bottom, and the bottom ends of the two connecting rods 21 are fixedly connected to the tops of the two inner plates 23 respectively by bolts. Each of the two mounting frames 20 has a threaded rod 22 on one side, with the two threaded rods 22 passing through the mounting frame 20 and the inner plate 23 sequentially via threaded grooves. When the drive motor 12 drives the bidirectional screw 8 to rotate, the nut seat 9 is securely connected to the inner plate 23 within the mounting frame 20 via the connecting rod 21. This design allows the support rod 19 to firmly support the spring and allows for adjustment of the spring's fixation level as needed, thereby enhancing the spring's fixation effect, reducing the risk of the spring slipping during cleaning, and facilitating the cleaning needs of springs of different sizes.

[0026] Furthermore, each of the two nut seats 9 has a slider 10 fixedly connected to its top, and the slider 10 is slidably connected to the top of the fixed frame 7 through a groove 11. When the drive motor 12 starts, the bidirectional screw 8 rotates, causing the nut seat 9 to move along the inside of the fixed frame 7, while the slider 10 slides synchronously within the groove 11. This design ensures smoother linear movement of the nut seat 9 and prevents the nut seat 9 from shaking when the bidirectional screw 8 rotates, thus improving the stability of equipment operation and extending its service life.

[0027] Furthermore, one end of the bidirectional screw 8 is rotatably connected to the inner wall of the fixed frame 7 via a rotating shaft, and the other end of the bidirectional screw 8 passes through the side wall of the fixed frame 7 via a bearing sleeve. A door 2 is rotatably connected to the outer side of the frame 1 via a hinge, and a side groove 13 is provided on one side of the top frame 3. This makes the entire device not only easy to maintain and repair, but also allows for convenient addition or replacement of cleaning fluid. In addition, the side groove 13 provides extra space for the vertical movement of the support frame 6, achieving the effect of improving equipment maintainability and reducing downtime.

[0028] Furthermore, each of the two support rods 19 has a protrusion 17 fixedly connected to one end, and the protrusion 17 is slidably connected to the inner wall of the support frame 6 through a movable groove 18. Driven by the drive motor 12, the support rods 19 can slide smoothly along the movable groove 18, realizing effective tensioning and release of the spring. This design ensures the accuracy and stability of the support rods 19 during tensioning operations, achieving the effects of improving spring fixing efficiency, reducing operational complexity, and also improving the overall working efficiency of the equipment.

[0029] In summary:

[0030] Before starting operation, first inspect and maintain the inside of the equipment through the door 2 set on the outside of the frame 1, and inject cleaning fluid into the frame 1 as needed. After starting the equipment, first put the spring to be cleaned onto the bearing rod 16 and the two support rods 19. The bearing rod 16 is fixedly connected to the inner side of the bearing frame 6, while the two support rods 19 are located on both sides of the inner ring of the spring, which plays an auxiliary positioning and tightening role. Then, install the inner plate 23 into the mounting frame 20 and screw the threaded rod 22 into the threaded groove to achieve a detachable connection. Then, fix the inner plate 23 to the bottom of the nut seat 9 through the connecting rod 21. Next, start the drive motor 12, and its output shaft drives the bidirectional screw 8 to rotate. Since the two ends of the bidirectional screw 8 are respectively connected to the two nut seats 9 by thread, and the top of the nut seat 9 is provided with a slider 10, which slides in the groove 11 opened on the top of the fixed frame 7. Therefore, when the bidirectional screw 8 rotates, the two nut seats 9 move in opposite directions and drive the support rod 19 to expand outward. One end of the support rod 19 is provided with a protrusion 17, which is slidably connected to the inner wall of the bearing frame 6 through the movable groove 18, thereby ensuring the smoothness and accuracy of the support rod 19 in the process of tightening the spring. After the spring is clamped and fixed, the hydraulic cylinder 5 is started, and its output shaft pushes the bearing frame 6 to move downward. The bearing frame 6 is provided with sliding blocks 14 on both sides, which cooperate with the sliding groove 15 on the inner wall of the top frame 3 to slide, so that the bearing frame 6 slides down steadily along the top frame 3. At the same time, the bearing rod 16 and the multiple fixed springs move down synchronously, and finally are completely immersed in the cleaning fluid in the frame 1 to complete the automatic cleaning operation. Throughout the process, the side groove 13 provided on one side of the top frame 3 provides space for the up and down movement of the bearing frame 6, further improving the stability of operation.The combination of the bearing rod 16 and the two support rods 19 enables multi-point support and positioning of the spring, solving the problem of spring slippage and tipping during traditional manual operation, and improving the safety and stability of the cleaning process. Secondly, the drive motor 12 rotates the bidirectional screw 8, controlling the two nut seats 9 to move in opposite directions. Through the connecting rod 21, the support rods 19 are simultaneously tightened on the spring. Combined with the guiding structure of the slider 10 and the groove 11, the linearity and stability of the support rod 19's movement are ensured, avoiding wobbling and deviation, thereby improving the accuracy and efficiency of spring clamping. Thirdly, the sliding engagement between the protrusion 17 on the support rod 19 and the movable groove 18 further enhances the guiding performance of the support rod 19 during tightening and releasing, reducing the risk of jamming or deviation, and improving equipment operation. The reliability of the operation is enhanced; in addition, the combination structure of the sliding blocks 14 and sliding grooves 15 on both sides of the bearing frame 6 allows the bearing frame 6 to slide smoothly along the top frame 3 under the action of the hydraulic cylinder 5, effectively preventing positional displacement caused by vibration or uneven load, and improving the continuity and stability of the cleaning process; finally, by setting the combination structure of the detachable inner plate 23 and the mounting frame 20, and using the threaded rod 22 and the threaded groove to achieve quick replacement and adjustment, the equipment's adaptability to springs of different sizes is enhanced, and the equipment's versatility and flexibility are improved; at the same time, the hinge connection structure of the door body 2 and the design of the side groove 13 greatly facilitate the daily maintenance of the equipment, the replacement of cleaning fluid and the handling of abnormalities, reduce downtime, and improve the maintainability and ease of use of the equipment.
