Description

Technical Field

[0001] This utility model relates to the field of spring processing and flattening technology, specifically to a flattening device for spring processing. Background Technology

[0002] Springs are essential components in many devices and are widely used inside various equipment and objects to achieve effects such as shock absorption and reciprocating motion. Spring machines refer to mechanical equipment used to produce springs, and are classified according to their functional characteristics as: compression spring machines, extension spring machines, universal spring machines, disc spring machines, and special-purpose spring machines.

[0003] The announcement number CN114985649B discloses a flattening device for spring processing, including a worktable. A fixed plate is fixedly connected to the top of the worktable. A square hole is opened on one side of the fixed plate. Fixed rails are fixedly connected to the inner walls of both sides of the square hole. Two sliding plates are slidably connected on the two fixed rails.

[0004] In the prior art, the guiding mechanism for the steel wire at the top of the existing device is difficult to adjust, making it difficult for the existing device to guide and transport steel wires of different diameters. Furthermore, it is prone to overheating and wear during long-term use. Therefore, this device provides a flattening device for spring processing. Utility Model Content

[0005] The purpose of this utility model is to provide a flattening device for spring processing to address the shortcomings of the existing technology and solve the aforementioned technical problems.

[0006] The present invention adopts the following technical solution: a flattening device for spring processing includes a processing support frame, a flattening processing support table fixedly installed on the lower front side of the processing support frame, a fixed plate fixedly installed on the upper front side of the processing support frame, an electric telescopic rod fixedly installed on the top of the fixed plate, and a flattening processing pressure plate fixedly installed at the output end of the electric telescopic rod; mounting boxes are fixedly installed on the left and right sides of the front side of the processing support frame, and bidirectional lead screws are rotatably installed on the left and right sides of the inner side of the mounting boxes, with a knob fixedly installed at the bottom of the left bidirectional lead screw; a movable groove is opened on the front side of the processing support frame, and a transmission gear is fixedly installed on the top of the bidirectional lead screw, with adjacent transmission gears meshing.

[0007] Furthermore, the front left and right sides of the mounting box are provided with limiting slide grooves, and multiple movable frames are threaded on the outer side of the bidirectional lead screw. The movable frames are slidably installed on the inner side of the limiting slide grooves.

[0008] Furthermore, a fixed box is provided on one side of the mobile frame, a fixing bolt is threaded on one side of the fixed box, a motor is fixedly installed on the left and right sides of the inner side of the fixed box, a drive shaft is fixedly installed on the output end of the motor, and a rotating guide wheel is fixedly installed on the outer side of the drive shaft.

[0009] Furthermore, the movable frame is I-shaped, with a placement groove on one side and a threaded hole on the inner side of the placement groove.

[0010] Furthermore, the fixing box fits into the placement groove, and the fixing bolt engages with the threaded hole.

[0011] Furthermore, the rotating guide wheel is I-shaped, and an anti-slip pad is provided on the inner side of the rotating guide wheel.

[0012] This utility model has the following beneficial effects:

[0013] The device places the steel wire, the raw material for the spring to be processed, in the middle of the rotating guide wheel. According to the size and specifications of the steel wire, the control knob drives the bidirectional lead screw to rotate. After the bidirectional lead screw rotates, it drives the moving frame to move through the threaded engagement. After the moving frame moves, it drives the rotating guide wheels on both sides to move, so that the steel wire can be transmitted inside the rotating guide wheel. The control motor drives the drive shaft and the rotating guide wheel to rotate, so that the rotating guide wheel can drive the steel wire to move.

[0014] To prevent overheating and wear during prolonged use of the rotating guide wheel, the control knob can be turned in the opposite direction to rotate the bidirectional lead screw. This allows the transmission gear to drive the bidirectional lead screw on the other side to rotate, causing the rotating guide wheel on one side of the moving frame to disengage from the steel wire, while the rotating guide wheel on the other side abuts against the steel wire. This makes the device more stable during operation and less prone to damage. After the steel wire moves to the top of the flattening support table, the electric telescopic rod can be controlled to lower the flattening plate to perform the flattening operation.

[0022] To make the objectives, technical solutions, and advantages of this utility model clearer, the technical solutions of this utility model will be clearly and completely described below in conjunction with specific embodiments and corresponding drawings. Obviously, the described embodiments are only a part of the embodiments of this utility model, and not all of them. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0023] The technical solutions provided by the various embodiments of this utility model are described in detail below with reference to the accompanying drawings.

[0024] A flattening device for spring processing includes a processing support frame 1, a flattening processing support table 2 fixedly installed on the lower front side of the processing support frame 1, a fixed plate 3 fixedly installed on the upper front side of the processing support frame 1, an electric telescopic rod 4 fixedly installed on the top of the fixed plate 3, and a flattening processing pressure plate 5 fixedly installed at the output end of the electric telescopic rod 4; mounting boxes 6 fixedly installed on the left and right sides of the front side of the processing support frame 1, and bidirectional lead screws 7 rotatably installed on the left and right sides of the inner side of the mounting boxes 6, with a knob 8 fixedly installed at the bottom of the left bidirectional lead screw 7; a movable groove is opened on the front side of the processing support frame 1, and a transmission gear 9 is fixedly installed on the top of the bidirectional lead screw 7, with adjacent transmission gears 9 meshing; the movable groove facilitates that the transmission gear 9 is less likely to collide with the processing support frame 1 during rotation.

[0025] The electric telescopic rod 4 drives the flattening processing lower pressure plate 5, achieving precise stamping and pressing of the spring. This design allows for adjustment of the lower pressure plate height as needed, ensuring processing accuracy and improving the automation and efficiency of the flattening process. The fixed design of the processing support frame 1 and the flattening processing support table 2 ensures the equipment remains stable and undeformed during operation, effectively supporting the spring and withstanding the impact forces during processing. This helps reduce vibration and displacement, ensuring the stability and accuracy of the processing.

[0026] The design of the bidirectional lead screw 7 allows for precise lateral adjustment of the flattening device. The knob 8 can be used to adjust the movement of the lead screw, thereby precisely controlling the pressure and position of the lower pressure plate 5. This structure not only improves adjustment accuracy but also facilitates quick adjustments by the operator based on different spring sizes. The movable groove design ensures that the transmission gear 9 does not collide with the processing support frame 1 during rotation, thus reducing the risk of equipment failure and wear. Furthermore, the precise meshing of the transmission gear 9 ensures smooth and stable movement, improving the durability and efficiency of the equipment.

[0027] The rational layout of various components, such as the mounting box 6, the double-acting lead screw, and the transmission gears, makes the space utilization of the equipment more efficient and reduces unnecessary floor space. The compact structure maintains ease of operation and improves the utilization rate of the overall operating space; the design of the movable slot not only ensures the normal operation of the transmission gears but also avoids contact between mechanical parts and the frame, reducing the risk of damage caused by collisions and thus improving the safety of the equipment.

[0028] The equipment's adjustment mechanisms (such as knobs, two-way lead screws, and gear systems) allow operators to easily adjust the equipment's operating status to accommodate the processing needs of springs of different specifications and shapes. Meanwhile, the structural design of each mechanical component facilitates daily maintenance and inspection, reducing downtime and extending the equipment's lifespan. The lower pressure plate can quickly and accurately complete the flattening operation, reducing manual intervention and improving production efficiency. Furthermore, the automated adjustment system simplifies operation and contributes to improved overall processing efficiency.

[0029] In a further preferred embodiment of this utility model, limiting grooves are provided on the left and right sides of the front side of the mounting box 6, and multiple movable frames 10 are threaded on the outer side of the bidirectional lead screw 7. The movable frames 10 are slidably installed on the inner side of the limiting grooves. This allows the bidirectional lead screw 7 to drive the movable frames 10 to move after rotation, and the bidirectional lead screw 7 can be driven to rotate in the opposite direction by the knob 8. This allows the multiple rotating guide wheels 15 to be used in rotation, making the device less prone to overheating and damage.

[0030] By designing multiple rotating guide wheels 15 and enabling them to be used in rotation, this solution effectively avoids a single guide wheel bearing excessive frictional load for an extended period, thereby reducing wear or damage to individual guide wheels due to overheating. Rotating the guide wheels helps to evenly distribute the heat generated by friction, preventing equipment malfunctions or damage due to overheating, thus extending the equipment's service life.

[0031] The movable frame 10 is slidably mounted in the limiting groove, allowing it to move smoothly following the rotation of the bidirectional lead screw 7, ensuring the smooth operation of the entire transmission system. The design of the limiting groove guarantees the stability of the movable frame during movement, avoiding machining accuracy problems caused by offset or misalignment, thereby improving the uniformity and stability of the system operation.

[0032] By rotating knob 8, the double-acting lead screw 7 on the other side rotates in the opposite direction, allowing the operator to easily adjust the rotation direction of the double-acting lead screw, enabling smooth switching between the moving frame and the guide wheels. This design not only improves operational flexibility but also makes equipment adjustment more precise and efficient. Furthermore, the operator can flexibly switch working states as needed, avoiding the burden of prolonged use of a single guide wheel, thus improving work efficiency and equipment reliability.

[0033] In a further preferred embodiment of the present invention, a fixed box 11 is provided on one side of the movable frame 10, a fixing bolt 12 is threadedly installed on one side of the fixed box 11, a motor 13 is fixedly installed on the left and right sides of the inner side of the fixed box 11, a drive shaft 14 is fixedly installed at the output end of the motor 13, and a rotating guide wheel 15 is fixedly installed on the outer side of the drive shaft 14.

[0034] The mounting box 11 provides stable support for the motor 13 and drive shaft 14, reducing vibration and displacement that may occur during operation and ensuring precise alignment between the motor and drive shaft. The motor 13 is fixed inside the mounting box, preventing loosening or displacement due to prolonged operation or external forces. This improves the stability and reliability of the drive system and extends the service life of the equipment.

[0035] The drive shaft 14 drives the rotating guide wheel 15 through the output end of the motor 13, ensuring the precision of the drive transmission process. The stability and precise operation of the rotating guide wheel can effectively transmit power to the moving frame 10, ensuring precise adjustment and efficient operation of the equipment during operation. By fixing the motor and drive shaft, it helps to improve power transmission efficiency and avoid possible power loss or transmission errors.

[0036] The mounting box 11 centrally mounts the motor 13 and drive shaft 14 together, effectively saving space and eliminating the need for additional support structures. This compact structure not only makes the equipment easier to install and maintain, but also improves overall efficiency and reliability through a rational spatial layout. The integration of key components such as the motor, drive shaft, and guide wheels within a confined space further enhances the design's economy and practicality.

[0037] In a further preferred embodiment of this utility model, the movable frame 10 is I-shaped, and a placement groove is provided on one side of the movable frame 10. A threaded hole is provided on the inner side of the placement groove. The fixed box 11 fits into the placement groove, and the fixing bolt 12 engages with the threaded hole. The placement groove facilitates the fixing box 11 to be fixed above the movable frame 10, and the fixing box 11 is locked by the fixing bolt 12, making the replacement and disassembly of the device more convenient and quick.

[0038] By designing placement slots and providing threaded holes on the movable frame 10, the fixed box 11 can be easily fitted into the placement slots. The fixing bolts 12, by engaging with the threaded holes, securely fix the fixed box 11 to the movable frame. This design makes the installation and disassembly of the fixed box simpler and faster, especially when maintenance or replacement is required, greatly saving time and labor, and improving the ease of equipment maintenance.

[0039] The I-beam-shaped movable frame 10 provides excellent strength and stability, enabling the entire equipment to maintain high rigidity during operation. The placement slot design further enhances the connection between the fixed box and the movable frame, ensuring that the fixed box 11 will not loosen due to vibration or external forces. The fixed box is securely locked by the engagement of the fixing bolts 12 with the threaded holes, enhancing the overall structural stability, thereby reducing vibration or displacement during operation and improving the reliability and safety of the equipment.

[0040] The I-beam-shaped mobile frame design not only provides high strength but also optimizes space utilization, resulting in a more compact and rational overall structure. The placement slots allow for easy installation of the mounting box onto the mobile frame, avoiding complex external support structures. This compact design reduces the equipment's footprint while improving its clean appearance, enhancing its overall aesthetics and design appeal.

[0041] In a further preferred embodiment of this utility model, the rotating guide wheel 15 is I-shaped, and an anti-slip pad is provided on the inner side of the rotating guide wheel 15; so that the transmission gear 9 can drive the bidirectional lead screw 7 on the other side to rotate, so that the rotating guide wheel 15 above the moving frame 10 on one side is disengaged from the steel wire, and the rotating guide wheel 15 on the other side abuts against the steel wire, making the device more stable during the driving process and less prone to damage. When the steel wire moves to the top of the flattening support table 2, the electric telescopic rod 4 can be controlled to drive the flattening lower platen 5 to descend and perform the flattening operation.

[0042] Specifically, the device places the spring material steel wire to be processed in the middle of the rotating guide wheel 15. Depending on the size and specifications of the steel wire, the knob 8 can be controlled to rotate the bidirectional lead screw 7. After rotation, the bidirectional lead screw 7, through its threaded engagement, drives the moving frame 10 to move. The moving frame 10, in turn, moves the rotating guide wheels 15 on both sides, allowing the steel wire to be driven within the rotating guide wheels 15. The motor 13 controls the drive shaft 14 and the rotating guide wheels 15 to rotate, enabling the rotating guide wheels 15 to drive the steel wire into… To prevent overheating and wear, the knob 8 can be controlled to rotate the bidirectional lead screw 7 in the opposite direction, so that the transmission gear 9 can drive the bidirectional lead screw 7 on the other side to rotate. This causes the rotating guide wheel 15 on one side of the moving frame 10 to disengage from the steel wire, while the rotating guide wheel 15 on the other side abuts against the steel wire. This makes the device more stable during the driving process and less prone to damage. After the steel wire moves to the top of the flattening support table 2, the electric telescopic rod 4 can be controlled to drive the flattening lower platen 5 to descend and perform the flattening operation.

[0043] The above description is merely an embodiment of this utility model and is not intended to limit the scope of this utility model. Various modifications and variations can be made to this utility model by those skilled in the art.
