Description

Technical Field

[0001] This utility model relates to the field of spring manufacturing equipment technology, specifically a spring coiling mechanism. Background Technology

[0002] A spring machine is a precision automated machine specifically designed to produce various types of elastic elements, including but not limited to compression springs, tension springs, and torsion springs. The spring production process involves more than simply stretching and winding the characteristic spring steel wire; it also requires consideration of the differences in end-connection methods for various applications. These differences necessitate that the springs be wound in different directions to form diverse shapes.

[0003] However, existing coiling mechanisms typically only achieve unidirectional rotary coiling through circular rotation and up-down movement. This design limits the flexibility of spring machines because additional coiling head mechanisms must be installed if springs with different coiling directions need to be manufactured. This means that multiple coiling heads may be required on the same spring machine to achieve rotary coiling from different directions to meet diverse production needs.

[0004] This design not only increases the complexity of the winding mechanism but also raises the difficulty and cost of operation. To achieve multi-directional winding, precise control of the extension, retraction, and rotation of each winding head is required, which undoubtedly increases the complexity of the machine and maintenance costs. Utility Model Content

[0005] This utility model provides a spring winding mechanism with a simple structure that can perform rotational winding processing from multiple directions.

[0006] The spring winding mechanism of this utility model includes a support plate that is slidably connected to the spring machine and moves up and down. The support plate is vertically provided with a side plate. A hollow rotating platform and a first motor that drives the rotating shaft of the hollow rotating platform to rotate in the vertical direction are installed on the upper part of the side plate. The rotating shaft of the hollow rotating platform is connected to a winding base plate, which drives the winding base plate to rotate in the vertical direction. The winding base plate is provided with a winding head for winding the spring and a second motor that drives the winding head to rotate.

[0007] The spring coiling mechanism described above achieves circular rotation of the coiling head in the vertical plane by rotating the coiling base plate vertically through a hollow rotary platform. This design cleverly meets the need for multi-directional rotational coiling in spring manufacturing, enabling the spring machine to flexibly produce springs of various shapes and sizes. The working principle of the hollow rotary platform is that the coiling base plate is fixed on the rotating shaft of the platform, and driven by a motor or other power source, the coiling base plate rotates 360 degrees vertically. This rotation mechanism drives the coiling head connected to the coiling base plate, enabling it to perform circular motion in the vertical direction, thereby achieving multi-angle coiling of the spring steel wire. The advantage of this design lies in its structural simplicity, reducing the number of mechanical parts and lowering mechanical complexity. Due to the simple structure, operators can more easily master the operation method, reducing operational difficulty. At the same time, the simplified structure also means lower maintenance costs and higher reliability, as the reduced number of parts lowers the probability of failure. Furthermore, since the hollow rotary platform can achieve multi-directional coiling, it reduces the need for additional coiling heads, thereby lowering the overall production cost.

[0008] As a further optimization of this utility model, it also includes an adjustment plate fixedly installed at one end of the support plate and a slider attached to the side of the adjustment plate for sliding connection with the spring mechanism. The adjustment plate is also vertically provided with an elongated through hole for bolts to pass through the fixed slider.

[0009] As a further optimization of this utility model, a bottom plate is provided between the support plate and the side plate, and a reinforcing rib is provided between the surface of the bottom plate and the side wall of the side plate for support connection.

[0010] As a further optimization of this utility model, it also includes a hollow reducer mounted on the curling base plate, wherein the second motor is mounted on the housing of the hollow reducer, and the output shaft of the second motor is connected to the input shaft of the hollow reducer, and the output shaft of the hollow reducer is connected to the curling head.

[0011] As a further optimization of this utility model, it also includes a curling mandrel that can rotate relative to the curling head, a right-angle reducer that drives the curling mandrel to rotate, and a third motor. The curling mandrel passes through the hollow part of the output shaft of the hollow reducer and the curling base plate and is rotatably connected to the right-angle reducer. The right-angle reducer is fixed on the curling base plate, and the third motor is installed on the housing of the right-angle reducer to drive the right-angle reducer. Attached Figure Description

[0015] The technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying 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 of ordinary skill in the art without creative effort are within the protection scope of this utility model.

[0016] It should be noted that if any directional indication (such as up, down, left, right, front, back, top, bottom, inside, outside, vertical, horizontal, longitudinal, counterclockwise, clockwise, circumferential, radial, axial, etc.) is involved in the embodiments of this utility model, the directional indication is only used to explain the relative positional relationship and movement of each component in a certain specific posture (as shown in the figure). If the specific posture changes, the directional indication will also change accordingly.

[0017] If the embodiments of this utility model involve descriptions such as "first" or "second," such descriptions are for descriptive purposes only and should not be construed as indicating or implying their relative importance or implicitly specifying the number of technical features indicated. Therefore, features defined with "first" or "second" may explicitly or implicitly include at least one of those features. Furthermore, the technical features of each embodiment can be combined arbitrarily. For the sake of brevity, not all possible combinations of the technical features in the embodiments are described; however, as long as these combinations of technical features do not contradict each other, they should all be considered within the scope of this specification.

[0018] like Figure 1 and Figure 2As shown, a spring-winding mechanism includes a support plate 1 slidably connected to the spring machine and capable of vertical movement. The support plate has a vertically mounted side plate 2. A hollow rotating platform 3 and a first motor 4 driving the rotating shaft of the hollow rotating platform to rotate vertically are mounted on the upper part of the side plate. The rotating shaft of the hollow rotating platform is connected to a winding base plate 5, causing the winding base plate to rotate circumferentially in the vertical direction. The winding base plate is equipped with a winding head 6 for winding springs and a second motor 7 driving the winding head to rotate. By rotating the winding base plate vertically through the hollow rotating platform, the winding head achieves circumferential rotation in the vertical plane. This design cleverly meets the need for multi-directional rotational winding in the spring manufacturing process, enabling the spring machine to flexibly produce springs of various shapes and sizes. The working principle of the hollow rotating platform is to fix the winding base plate on the rotating shaft of the hollow rotating platform, and through a motor drive or other power source, cause the winding base plate to rotate 360 ​​degrees vertically. This rotating mechanism drives a coiling head connected to the coiling base plate, enabling it to perform circular motion in the vertical direction, thus achieving multi-angle coiling of the spring steel wire. The advantage of this design lies in its structural simplicity, reducing the number of mechanical parts and lowering mechanical complexity. Due to its simple structure, operators can more easily master the operation method, reducing operational difficulty. At the same time, the simplified structure also means lower maintenance costs and higher reliability, as the reduced number of parts lowers the probability of failure. Furthermore, because the hollow rotary platform can achieve multi-directional coiling, it reduces the need for additional coiling heads, thereby lowering overall production costs.

[0019] It also includes an adjusting plate 8 fixedly installed at one end of the support plate 1 and a slider 9 fitted to the side of the adjusting plate for sliding connection with the spring machine. The adjusting plate 8 is also vertically provided with an elongated through hole 10 for bolts to pass through and fix the slider. The slider can be adjusted in position by means of the elongated through hole to facilitate installation on the spring machine. The slider is slidably installed in the slide rail of the spring machine, so that the entire coiling mechanism can move relative to the spring machine, making it easy for the coiling mechanism to move to the position where the spring needs to be coiled.

[0020] A base plate 11 is provided between the support plate 1 and the side plate 2. A reinforcing rib 12 is provided between the surface of the base plate and the side wall of the side plate for support connection. By setting a base plate between the support plate and the side plate, the support area of ​​the side plate is increased. The reinforcing rib between the surface of the base plate and the side wall of the side plate can strengthen the support strength of the side plate.

[0021] It also includes a hollow reducer 13 mounted on the curling base plate 5. The second motor 7 is mounted on the housing of the hollow reducer, and its output shaft is connected to the input shaft of the hollow reducer. The output shaft of the hollow reducer is connected to the curling head. The hollow reducer can better control the speed reduction of the curling head, making the speed and angle control more precise.

[0022] The existing structure of the curling head generally includes a curling mandrel 14 through which a steel strip passes, a clamping boss 15 on one side of the curling mandrel for abutting the bent steel strip, and a groove 18 in the middle of the curling mandrel for the steel strip to pass through. Furthermore, it also includes a curling mandrel 14 that can rotate relative to the curling head, a right-angle reducer 16 that drives the curling mandrel to rotate, and a third motor 17. The curling mandrel passes through the hollow output shaft of the hollow reducer and the curling base plate and is rotatably connected to the right-angle reducer. The right-angle reducer is fixed on the curling base plate, and the third motor is mounted on the housing of the right-angle reducer to drive it. Compared to the traditional fixed curling mandrel that can only control one direction, the cooperation of the third motor and the right-angle reducer allows the curling mandrel to rotate relative to the curling head, so that a certain angle can be formed between the groove of the curling mandrel for the steel strip to pass through and the clamping boss, allowing for the rounding of 360-degree bends.

[0023] The upper surface of the curling head remains flush with the first rotation center line 19 of the rotation axis of the hollow rotating platform in the horizontal plane. When the curling head rotates in a vertical or inclined plane, the upper surface of the curling head remains flush with the first rotation center line 19 of the rotation axis of the hollow rotating platform. The second rotation center line 20 of the curling head intersects with the first rotation center line and is perpendicular to it. Figure 3 As shown.

[0024] The above description is only a preferred embodiment of the present utility model and does not limit the patent scope of the present utility model. All equivalent structural transformations made under the concept of the present utility model and using the contents of the present utility model specification and drawings, or direct / indirect applications in other related technical fields, are included in the patent protection scope of the present utility model.

[0025] The embodiments of the present invention have been described in detail above with reference to the accompanying drawings. However, the present invention is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of the present invention.
