Description

Technical Field

[0001] The utility model relates to the technical field of spring steel wire processing, in particular to a spring steel wire processing and cutting device. Background Art

[0002] Spring steel wire is a type of steel wire used to make springs or steel wire profiles. Cutting is a common operation step in the spring steel wire processing process. A cutting device can be used to cut the spring steel wire into various sizes and then processed into molded parts for different uses. In related technologies, cutting devices usually use a cutter to cut the spring steel wire. However, during the cutting process, the cut portion of the spring steel wire will be squeezed by the knife. Under the action of the squeezing force, the spring steel wire has the probability of deformation. Existing cutting devices usually only have a cutting function and cannot shape the cut portion. Therefore, when using this type of cutting device to cut the spring steel wire, the quality of the cut spring steel wire cannot be guaranteed. In addition, the spring steel wire may bend or deform before cutting. Directly cutting the spring steel wire also cannot guarantee the cutting quality. Based on this, the present application proposes a spring steel wire processing and cutting device. Utility Model Content

The pressing plate 9 is located directly above the lifting platform 7, and the pressing plate 9 and the lifting platform 7 have the same size. Through the arrangement of the lifting platform 7 and the pressing plate 9, the position of the spring steel wire placed on the workbench 1 can be limited.

[0026] Both ends of the workbench 1 are provided with a straightening structure, which includes a mobile frame 3 connected to the workbench 1 through a hydraulic telescopic rod 21, a double-headed ball screw 4 movably connected to the top of the mobile frame 3, ball nuts threadedly connected to the outer rings of both ends of the double-headed ball screw 4, and a clamping plate 5 fixedly connected to the ball nut.

A servo motor is provided at one end of the movable frame 3, and the double-headed ball screw 4 is driven by the servo motor. The servo motor can drive the double-headed ball screw 4 to rotate. The rotation of the double-headed ball screw 4 causes the distance between the two ball nuts threaded therewith to change. When the ball nut moves, it drives the clamping plate 5 fixed thereto to move. The two clamping plates 5 in the straightening structure can clamp and fix the spring steel wire. At this time, when the hydraulic telescopic rod 21 is extended, the coordinated use of the two straightening structures can realize the pulling of the spring steel wire, so that the part to be cut is straightened, which is convenient for cutting the spring steel wire.

[0027] It can be seen from the above description that when the device is in use, the straightening structure can be used to straighten the spring steel wire, thereby facilitating the cutting of the spring steel wire.

[0028] The cutting and shaping structure includes a cutting table 6 and a fixed plate 8. The middle part of the top of the workbench 1 is connected to the cutting table 6 through a lifting and translation structure. The lifting and translation structure includes a hydraulic telescopic rod four 13 connected to the workbench 1 and a hydraulic telescopic rod five 14 fixedly connected to the end of the output shaft of the hydraulic telescopic rod four 13. The end of the output shaft of the hydraulic telescopic rod five 14 is fixedly connected to the bottom of the cutting table 6. Through the setting of the lifting and translation structure, the operation of the hydraulic telescopic rod five 14 can change the height of the cutting table 6, and the operation of the hydraulic telescopic rod four 13 can change the position of the cutting table 6 in the horizontal direction.

[0029] In addition, the distance between the semicircular groove on the clamping plate 5 and the top of the workbench 1 is greater than the thickness of the cutting table 6. The thickness of the cutting table 6 can be set according to needs and will not be described here. With such a setting, when the device is in use, the cutting table 6 can be moved above the workbench 1, so that the hydraulic telescopic rod 4 13 can drive the cutting table 6 to move horizontally.

[0030] A cutting groove 22 is provided in the middle of the cutting table 6. One side of the cutting table 6 is connected to a lower correction wheel 23 adapted to the spring steel wire through a hydraulic telescopic rod 3 20. The extension and retraction of the hydraulic telescopic rod 3 20 can change the position of the lower correction wheel 23. After the spring steel wire is cut, the rolling of the lower correction wheel 23 can realize the shaping of the cutting part to avoid bending or flattening of the cutting part.

[0031] A movable block 12 is movably connected to the middle of the support plate 2. A hydraulic telescopic rod 7 (11) is fixedly connected to the bottom of the support plate 2. The end of the output shaft of the hydraulic telescopic rod 7 (11) is fixedly connected to the movable block 12. The extension and retraction of the hydraulic telescopic rod 7 (11) can change the position of the movable block 12. The fixed plate 8 and the movable block 12 are connected by a hydraulic telescopic rod 8 (19). The middle of the top of the cutting table 6 and the middle of the bottom of the fixed plate 8 are both provided with semicircular grooves adapted for the spring steel wire. The inner wall of the semicircular grooves is fixedly connected to the inner wall of the semicircular grooves. The combined use of the fixed plate 8 and the cutting table 6 can press the spring steel wire, fix the spring steel wire in place, and facilitate cutting of the spring steel wire.

[0032] A cutter 24 is movably connected to the middle of the fixed plate 8. The cutter 24 is located directly above the cutting groove 22. The cutter 24 is connected to the movable block 12 via a hydraulic telescopic rod 18. The extension and retraction of the hydraulic telescopic rod 18 can change the position of the cutter 24. When the device is in use, the cutter 24 can be used to cut the spring steel wire.

[0033] An upper straightening wheel 25, compatible with the spring wire, is connected to the side of the fixed plate 8, away from the hydraulic telescopic rod 8 19, via the hydraulic telescopic rod 10 17. The upper straightening wheel 25 is located directly above the lower straightening wheel 23. The combined use of the upper straightening wheel 25 and the lower straightening wheel 23 straightens and rounds the cut portion of the spring wire, improving cutting quality. The upper straightening wheel 25 and the lower straightening wheel 23 have the same structure.

[0034] A visual sensor 10 is provided at the bottom of the fixing plate 8. The visual sensor 10 can detect the spring steel wire so that the device can judge whether the shape of the spring steel wire needs to be adjusted before or after cutting based on the detection results.

[0035] The electrical components and hydraulic telescopic rods involved in this application are all existing technologies. Those skilled in the art are familiar with their connection methods. Through these people, all the electrical components in this application are connected to their corresponding power supplies through wires, and the hydraulic telescopic rods are connected to the corresponding hydraulic pump stations. According to actual conditions, appropriate controllers are selected to meet control requirements. For specific connections and control sequences, please refer to the description below. The electrical connections between the electrical components are completed in a sequential working order. The detailed connection methods are well known in the art. The following mainly introduces the working principles and processes, and no further explanation of electrical control is given.

[0036] To sum up: when the spring steel wire processing and cutting device is in use, the hydraulic telescopic rod 15 is extended, and the hydraulic telescopic rod 15 drives the lifting platform 7 connected thereto to move up until the top of the lifting platform 7 and the bottom of the semicircular groove set on the clamping plate 5 are at the same height. During the spring steel wire processing process, the part of the spring steel wire to be cut is placed on the two lifting platforms 7, and the visual sensor 10 detects this part of the spring steel wire. If the visual sensor 10 detects that the spring steel wire needs to be straightened or its position is not on the semicircular groove on the cutting table 6, the hydraulic telescopic rod 6 16 is extended, and the hydraulic telescopic rod 6 16 drives the pressure plate 9 fixedly connected thereto to move down. During the downward movement of the pressure plate 9, the upward protruding spring steel wire can be pressed until the spring steel wire is located between the pressure plate 9 and the lifting platform 7. The spring steel wire is in contact with both the pressure plate 9 and the lifting platform 7, and under the action of external force, the spring steel wire can move. The servo motor in the straightening structure works, and the operation of the servo motor causes the two clamping plates 5 in the straightening structure to approach each other until the spring steel wire is clamped and fixed by the clamping plates 5. At this time, the spring steel wire is located on the semicircular groove on the cutting table 6, and the hydraulic telescopic rod 21 is extended. The hydraulic telescopic rod 21 drives the mobile frame 3 connected thereto away from the workbench 1. The two straightening structures are used in coordination to pull the spring steel wire until the spring steel wire is straightened. If the visual sensor 10 detects that the spring steel wire does not need to be straightened or adjusted in position, after the straightening structure clamps and fixes the spring steel wire, the hydraulic telescopic rod five 14 drives the cutting table 6 to move up until the spring steel wire is tightly fitted with the semicircular groove on the cutting table 6 and the lower correction wheel 23. At this time, the cutting table 6 is located above the workbench 1, and the hydraulic telescopic rod eight 19 and the hydraulic telescopic rod ten 17 are both extended. The hydraulic telescopic rod eight 19 drives the fixed plate 8 to move down until the fixed plate 8 is tightly fitted with the top of the cutting table 6. The hydraulic telescopic rod ten 17 drives the upper correction wheel 25 to move down until the upper correction wheel 25 is fitted with the lower correction wheel 23. The spring steel wire is fixed by the cutting table 6 and the fixed plate 8 as well as the upper correction wheel 25 and the lower correction wheel 23. The hydraulic telescopic rod nine 18 is extended. The hydraulic telescopic rod nine 18 drives the cutter 24 to move down, and the cutter 24 can achieve straightening of the spring steel wire. Cutting of the spring steel wire. After the spring steel wire is cut, the fixed plate 8 and the cutter 24 are reset, and the visual sensor 10 detects the cut part of the spring steel wire. If the cut part needs to be shaped, the hydraulic telescopic rod 7 11 and the hydraulic telescopic rod 4 13 both work. The coordinated use of the hydraulic telescopic rod 7 11 and the hydraulic telescopic rod 4 13 enables the upper correction wheel 25 and the lower correction wheel 23 to roll the cut part of the spring steel wire to avoid deformation of the cut part of the spring steel wire and improve the cutting quality. During the cutting process, the pressing plate 9 and the lifting platform 7 are reset to avoid the pressing plate 9 restricting the movement of the fixed plate 8 and the lifting platform 7 restricting the movement of the cutting platform 6. After the cut part of the spring steel wire is corrected, the cutting and shaping structure is reset, the straightening structure and the pressing plate 9 are released to limit the spring steel wire, and the cut spring steel wire is removed, and the device can continue to work.
