Description

Technical Field

[0001] This utility model relates to the field of spring cutting technology, and in particular to a cutting device for processing mechanical springs that can cut continuously. Background Technology

[0002] Mechanical spring processing refers to the process of processing metal materials into spring elements with elasticity and energy storage function through a series of mechanical processing steps. Spring processing usually includes material selection, wire stretching, coiling, heat treatment, end processing, surface treatment and other steps to ensure that the spring has the required elasticity and durability.

[0003] In the winding and forming stage of the mechanical spring, a cutting device is required. After entering the winding and forming stage, the wire is transported to the guide component by the conveying device. The wire is guided to bend and coil by the guide component. As the conveying device continues to transport the wire, the winding and coiling is guided by the guide component, and the winding and forming of the spring is finally completed. Then, the cutter descending from the top cuts the connection between the coiled spring and the uncoiled wire, thus obtaining a preliminary formed spring.

[0004] Existing cutting devices typically use a cylinder to drive the cutter downwards for cutting. However, in spring processing, the cutter needs to perform multiple cuts, requiring the cylinder to continuously drive the cutter up and down. This method places high demands on the cylinder's lifespan, as the cylinder needs to constantly extend and retract its output end. After prolonged use, the cylinder's performance will decline, affecting spring cutting and making it inconvenient to use. Utility Model Content

Detailed Implementation

[0028] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention.

[0029] Example 1

[0030] Reference Figure 1 and Figure 2 This is the first embodiment of the present invention, which provides a cutting device for continuously cutting mechanical springs, comprising:

[0031] The chassis 1 has a conveying component 2 on one side and a guiding component 3 on the outer surface of the chassis 1.

[0032] The reciprocating assembly 4 is disposed inside the housing 1. The reciprocating assembly 4 includes a drive shaft 404 movably installed inside the housing 1. A guide plate 405 is installed at one end of the drive shaft 404 near the conveying component 2. A drive wheel 406 is movably installed inside the guide plate 405. A moving rod 407 is installed on the side of the drive wheel 406 away from the guide plate 405. A moving seat 408 is installed at the end of the moving rod 407 away from the guide plate 405.

[0033] like Figure 1 as well as Figure 2 In this embodiment, a servo motor 401 is installed inside the chassis 1, and a worm gear 402 is movably installed inside the chassis 1. The output end of the servo motor 401 is connected to one end of the worm gear 402. A worm wheel 403 is installed on the outer surface of the transmission shaft 404, and the worm wheel 403 is meshed with the worm gear 402.

[0034] like Figure 2In this embodiment, a guide groove is provided on the side of the guide disc 405 near the movable seat 408, and a transmission wheel 406 is disposed inside the guide groove. A sub-groove is provided inside the guide groove on the outer surface of the guide disc 405, and a limiting protrusion that cooperates with the sub-groove is provided on the outer surface of the transmission wheel 406. The guide groove on the outer surface of the guide disc 405 can be divided into three parts. The upper half of the guide groove is semi-circular and is a lifting part. When the lifting part of the guide groove rotates to the top, it can drive the moving rod 407 to rise through the transmission wheel 406, thereby controlling the cutting head 506 to rise and avoiding affecting the spring coiling formation. The top of the guide groove is a recessed part. When the recessed part moves to the top, its height is lower than the height of the lifting part, so that the transmission wheel 406... When the 06 part is engaged with the lower part, the cutting head 506 can descend to the lowest point. Both ends of the lifting part and the two ends of the lower part are connected to moving parts. When the transmission wheel 406 engages with the moving part, the moving rod 407 drives the moving seat 408 to rise or fall. When the rotation of the guide plate 405 drives the part engaged with the transmission wheel 406 to move from the lifting part to the lower part, the cutting head 506 descends, thereby cutting the spring. When the rotation of the guide plate 405 drives the part engaged with the transmission wheel 406 to move from the lower part to the lifting part, the cutting head 506 rises. After the cutting is completed, the cutting head 506 rises away from the spring to avoid affecting the spring winding and forming.

[0035] like Figure 1 as well as Figure 2 In this embodiment, a rectangular opening is provided on the outer surface of the housing 1 for the lifting and lowering of the moving rod 407. Slide rails are installed on both sides of the rectangular opening on the outer surface of the housing 1. A slider that cooperates with the slide rail is installed on the side of the moving seat 408 near the housing 1. The rectangular opening facilitates the lifting and lowering of the moving rod 407. Through the cooperation of the slide rail and the slider, the vertical lifting and lowering of the moving seat 408 is limited, thereby restricting the moving rod 407 and the transmission wheel 406 to only move vertically, thus ensuring that the rotation of the guide plate 405 can drive the moving rod 407 to lift and lower in a specified process.

[0036] Furthermore, the servo motor 401 synchronously drives the worm gear 402 to rotate. The servo motor 401 drives the worm gear 402 to rotate at a constant speed, which in turn drives the worm wheel 403 to rotate. The worm wheel 403 drives the transmission shaft 404 to rotate, and the transmission shaft 404 drives the guide disk 405 to rotate. When the spring is in the process of coiling and forming, the lifting part of the guide groove on the outer surface of the guide disk 405 cooperates with the transmission wheel 406, thereby ensuring that the moving rod 407 drives the moving seat 408 to a high point, thereby driving the cutting head 506 away from the coiled and formed spring to avoid affecting the spring forming. After the forming is completed, the spring is output... When the conveying component 2 stops rotating, the servo motor 401 continues to drive the worm gear 402 to rotate at a constant speed, thereby causing the lower part of the guide groove on the outer surface of the guide plate 405 to rotate upward, thus driving the transmission wheel 406 to descend, and then driving the moving seat 408 to descend through the moving rod 407, thereby driving the cutting head 506 to cut the spring, so that the coiled spring is separated. The connection relationship, working principle and operation sequence between the conveying component 2, the guide component 3 and other components are existing technologies and are common knowledge known to those skilled in the art, and will not be elaborated on here.

[0037] Example 2

[0038] Reference Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5 This is the second embodiment of the present invention, which is based on the previous embodiment. The cutting component 5 is disposed inside the movable seat 408. The cutting component 5 includes a threaded rod 501 movably installed inside the movable seat 408. A threaded sleeve 502 is engaged with the outer surface of the threaded rod 501. An L-shaped moving block 503 is installed on the outer surface of the threaded sleeve 502. An insertion block 504 is inserted into the side of the L-shaped moving block 503 away from the movable seat 408. A cutting head 506 is installed at the bottom of the insertion block 504.

[0039] like Figure 1 , Figure 2 as well as Figure 3In this embodiment, a sliding block 505 is slidably provided on the side of the movable base 408 away from the chassis 1. Two support blocks 508 are installed on the bottom of the L-shaped movable block 503 near the sliding block 505. A rotating baffle 507 is hinged to the top of the L-shaped movable block 503 near the sliding block 505. A torsion spring is provided at the hinge part between the rotating baffle 507 and the L-shaped movable block 503. After the sliding block 505 slides to one side of the L-shaped movable block 503, its bottom abuts against the upper surface of the support block 508, thereby supporting the sliding block 505 through the support block 508. During the sliding process, the rotating baffle 507 needs to be rotated to open. When the sliding block 505 abuts against the support block 508, the rotating baffle 507 is released. Through the setting of the torsion spring, the rotating baffle 507 is driven to rotate automatically, thereby locking the top of the sliding block 505. Thus, the sliding block 505 restricts the plug-in block 504 from disengaging from the L-shaped movable block 503.

[0040] like Figure 4 as well as Figure 5 In this embodiment, T-shaped strips are provided on both ends of the sliding block 505 near the movable seat 408 and on both sides of the L-shaped movable block 503. The movable seat 408 has an inner cavity for the movement of the L-shaped movable block 503. T-shaped limiting grooves that cooperate with the T-shaped strips are provided on both sides of the inner cavity of the movable seat 408 and on the outer surface of the movable seat 408. Through the cooperation of the T-shaped strips and the T-shaped limiting grooves, the vertical movement of the L-shaped movable seat 408 and the sliding block 505 is limited, thus preventing deviation.

[0041] Furthermore, rotating the threaded rod 501 causes the L-shaped moving block 503 to rise and fall via the threaded sleeve 502, thereby adjusting the height of the insertion block 504 and the cutting head 506 at the bottom of the insertion block 504. This facilitates height adjustment of the cutting head 506 for processing springs of different specifications. By rotating the baffle 507 and the support block 508, the sliding block 505 is locked. The sliding block 505 prevents the insertion block 504 from separating from the L-shaped moving block 503, thus allowing the cutting head 506 to be easily replaced by removing the sliding block 505, facilitating the cutting of springs of different specifications.

[0042] Working principle: When processing springs, before cutting, the cutting head 506 needs to be adjusted according to the specifications of the spring being processed. When processing larger springs, the threaded rod 501 is rotated using a wrench or other tools, which causes the threaded sleeve 502 to rise and fall on the outer surface of the threaded rod 501. This, in turn, causes the L-shaped moving block 503 to rise and fall, thereby causing the insertion block 504 and the cutting head 506 at the bottom of the insertion block 504 to rise and fall. This allows for adjustment of the height of the cutting head 506, facilitating the cutting of springs of different specifications. A suitable cutting head 506 can be selected according to the cutting requirements. Rotating the rotating baffle 507 releases the sliding block 505. Lock the plug block 504, then slide the sliding block 505 upwards to unlock the plug block 504. At this point, the plug block 504 and the cutting head 506 can be pulled out of the L-shaped moving block 503. Replace the cutting head 506 with a suitable one to re-insert the plug block 504 into the L-shaped moving block 503. Then, rotate the baffle 507 to slide the sliding block 505 above the support block 508. After releasing the baffle 507, the torsion spring causes the baffle 507 to engage with the upper surface of the sliding block 505, thus locking the L-shaped moving block 503 and the sliding block 505. This allows the L-shaped moving block 503 to synchronously raise and lower the sliding block 505, maintaining the limit position of the plug block 504. 4. This prevents the plug block 504 from detaching from the L-shaped moving block 503, thus enabling the replacement of the appropriate cutting head 506 and allowing adjustment of the height of the cutting head 506 for convenient cutting. After the spring begins to coil, the wire is conveyed by the conveying component 2, driving the wire to continuously move forward and reach the guide component 3. The guide component 3 guides the wire to coil. During the coiling process, the servo motor 401 synchronously drives the worm gear 402 to rotate. The servo motor 401 drives the worm gear 402 to rotate at a constant speed, which in turn drives the worm wheel 403 to rotate. The worm wheel 403 drives the transmission shaft 404 to rotate, and the transmission shaft 404 drives the guide disc 405 to rotate. When the spring is in the disc... During the winding process, the lifting part of the guide groove on the outer surface of the guide disc 405 cooperates with the transmission wheel 406 to ensure that the moving rod 407 drives the moving seat 408 to a high point, thereby driving the cutting head 506 away from the coiled spring to avoid affecting the spring forming. After the forming is completed, the conveying component 2 stops rotating. At this time, the servo motor 401 continues to drive the worm gear 402 to rotate at a constant speed, thereby causing the sinking part of the guide groove on the outer surface of the guide disc 405 to rotate to the top, thereby driving the transmission wheel 406 to descend, and then driving the moving rod 407 to drive the moving seat 408 to descend, thereby driving the cutting head 506 to cut the spring, so that the coiled spring is separated, thus completing the spring cutting.
