Description

Technical Field

[0001] This utility model relates to the field of spring cold coiling machine technology, and in particular to a reinforced combined feeding guide plate for spring cold coiling machine. Background Technology

[0002] In existing spring cold coiling machine technology, the feeding guide plate, as a key component, has long played an indispensable role. Its main function is to accurately feed the spring steel wire into the working area of ​​the coiling machine, ensuring precise control and efficient production of the springs during the coiling process. However, with the continuous development of production technology, especially in the process of coiling springs with small winding ratios, existing feeding guide plates face many technical challenges. These challenges directly affect the service life, production efficiency, and maintenance costs of the feeding guide plate.

[0003] For example, in the production of springs with small winding ratios, the tension and friction of the steel wire are relatively large due to the small winding ratio. This results in significant pressure and friction on the feeding guide during use, causing severe wear on the guide surface, rendering it unusable. However, most current feeding guides are integral structures, requiring replacement of the entire unit after wear. This necessitates replacing the entire feeding guide each time, leading to prolonged downtime, reduced production efficiency, and increased replacement costs. Therefore, this invention proposes a reinforced combined feeding guide for spring cold coiling machines to address the problems existing in the prior art. Utility Model Content

[0004] To address the aforementioned problems, the purpose of this utility model is to propose a reinforced combined feeding guide for a spring cold coiler. This reinforced combined feeding guide for a spring cold coiler has the advantage of modular design, and only the groove head needs to be replaced when damaged, thus solving the problems in the prior art.

[0005] To achieve the purpose of this utility model, the utility model is implemented through the following technical solution: a reinforced combined feeding guide plate for a spring cold coiling machine, including a sleeve, a feeding plate installed on the inner side of the sleeve, a feeding hole provided in the inner cavity of the feeding plate, an installation groove provided in the sleeve, a groove head installed on the inner side of the sleeve, and a feeding groove provided on the groove head, the position of the feeding groove corresponding to the feeding hole, one end of the groove head extending into the installation groove and connected to the sleeve through a clamping block, and the end of the installation groove away from the feeding plate communicating with the outside.

[0006] A further improvement is that a limiting groove is provided on the side of the groove head away from the feeding groove, one end of the clamping block extends into the limiting groove and fits against the groove head, and the clamping block is fixedly connected to the sleeve by bolts.

[0007] A further improvement is that the cross-section of the insert is U-shaped, and the insert is provided with two sets of staggered positioning grooves. Positioning blocks are installed on the feeding plate, and the number and position of the positioning blocks correspond to the positioning grooves. The positioning blocks are located in the positioning grooves.

[0008] A further improvement is that: the inner side of the insert is provided with a limiting slot, and the position of the limiting slot corresponds to the groove head. One end of the groove head extends into the limiting slot and fits into the insert.

[0009] A further improvement is that an extension is installed at the upper end of the insert, and the extension is integrally formed with the insert, with the side of the extension away from the groove head perpendicular to the insert.

[0010] A further improvement is that the lower end of the groove head is provided with an arc-shaped structure.

[0011] A further improvement is that the clamping block is provided with through holes, and there are several groups of through holes.

[0012] The beneficial effects of this utility model are as follows: This reinforced combined feeding guide plate for spring cold coiling machines adopts a modular design, using the groove head as the force-bearing part, which bears the main friction and pressure, ensuring effective management of the stress-concentrated parts during long-term use. Furthermore, the addition of inserts to distribute the force further reduces the probability of localized wear. Moreover, unlike traditional designs that require replacing the entire feeding guide plate, when wear occurs, only the corresponding groove head needs to be replaced, without replacing the entire feeding guide plate. This not only saves material costs but also reduces maintenance time, further lowering operating costs. Attached Figure Description

[0021] To deepen the understanding of this utility model, the following detailed description will be provided in conjunction with embodiments. These embodiments are only used to explain this utility model and do not constitute a limitation on the scope of protection of this utility model.

[0022] according to Figures 1-6 As shown, this embodiment proposes a reinforced combined feeding guide plate for a spring cold coiling machine, including a sleeve 1. A feeding plate 2 is installed on the inner side of the sleeve 1. The sleeve 1 has a U-shaped cross-section, ensuring good strength and stability, and providing reliable support for the installation of the feeding plate 2. The sleeve 1 has two sets of staggered positioning grooves 9. Positioning blocks 10 are installed on the feeding plate 2, and the number and position of the positioning blocks 10 correspond to the positioning grooves 9. The positioning blocks 10 are located within the positioning grooves 9. The cooperation between the positioning blocks 10 and the positioning grooves 9 enhances the fitting accuracy between the feeding plate 2 and the sleeve 1, and also ensures that the feeding plate 2 can be smoothly positioned during installation, thus ensuring that the feeding plate 2 is in an accurate position during operation. Therefore, the feeding plate 2 can be accurately aligned after installation. Figure 1 As shown, the upper and lower sides of the insert 1 contain corresponding baffles, so that after the feeding plate 2 is installed, the insert 1 can fit well with the feeding plate 2. In specific implementation, the feeding plate 2 and the insert 1 can be connected by bolts.

[0023] The inner cavity of the feeding plate 2 is provided with a feeding hole 3, and the sleeve 1 is provided with an installation groove 4. A groove head 5 is installed on the inner side of the sleeve 1, and a feeding groove 6 is provided on the groove head 5. The position of the feeding groove 6 corresponds to the feeding hole 3, and the end of the feeding groove 6 away from the feeding plate 2 is connected to the outside, forming an effective feeding channel. The cooperation between the feeding hole 3 and the feeding groove 6 enables precise guidance of the spring steel wire, ensuring that the spring steel wire can enter the working area of ​​the winding equipment stably and smoothly during the feeding process.

[0024] One end of the groove head 5 extends into the mounting groove 4 and is connected to the sleeve 1 via the clamping block 7. This ensures a tight fit between the groove head 5 and the sleeve 1, improving the overall stability of the feeding guide plate. Combined with the limiting latch 11, this ensures the feeding plate 2 operates stably during use and reduces loosening or displacement caused by external impacts or friction. Furthermore, a limiting groove 8 is provided on the side of the groove head 5 away from the feeding groove 6. One end of the clamping block 7 extends into the limiting groove 8 and fits against the groove head 5. The clamping block 7 is fixedly connected to the sleeve 1 by bolts. Thus, the cooperation between the clamping block 7 and the limiting groove 8 not only ensures a tight fit between the clamping block 7 and the groove head 5 but also prevents the clamping block 7 from shifting during installation, further enhancing the reliability of the overall structure. Based on this, the clamping block 7 is fixedly connected to the sleeve 1 by bolts, providing a stable and durable fixing method that ensures the feeding guide plate maintains high precision and stability over a long period during operation.

[0025] During installation, first align the clamping block 7 with the groove head 5 to form a single unit, then insert it into the mounting groove 4 and push it all the way down. Finally, secure it with bolts. The entire process is convenient and quick, which facilitates the installation and disassembly of the groove head 5, avoids complicated adjustments or operating steps, and improves production efficiency.

[0026] Furthermore, the clamping block 7 is provided with through holes 14, and there are several groups of through holes 14. In this embodiment, three groups of through holes 14 are evenly provided. The function of the through holes 14 is to facilitate the passage of bolts. The lower end of the groove head 5 is provided with an arc-shaped structure 13. The function of the arc-shaped structure 13 is to prevent the groove head 5 from affecting the use of the through holes 14.

[0027] The inner side of the insert 1 is provided with a limiting slot 11, and the position of the limiting slot 11 corresponds to the groove head 5. One end of the groove head 5 extends into the limiting slot 11 and fits into the insert 1. When the groove head 5 is installed, its end fits into the limiting slot 11, thereby ensuring that the groove head 5 always stays in the correct position as designed, avoiding the problem of unstable feeding or reduced production accuracy caused by the position of the groove head.

[0028] An extension 12 is installed at the upper end of the sleeve 1, and the extension 12 is integrally formed with the sleeve 1. The side of the extension 12 away from the groove head 5 is perpendicular to the sleeve 1. During operation, the sleeve 1 is connected to external equipment (spring cold coiling machine) by bolts, with its connection point located between the extension 12 and the sleeve 1, and connected to the extension 12. It can also be connected to both the extension 12 and the sleeve 1 simultaneously. Through this design, the force is no longer concentrated in a certain part, but is evenly distributed to the external equipment through the overall structure of the sleeve 1. This not only reduces local wear on the groove head 5 and the sleeve 1, but also greatly reduces the risk of damage caused by excessive force concentration. Therefore, the extension 12 plays a dual role of connection and force distribution, enhancing the stability of the entire structure and ensuring the efficient operation of the feeding guide plate in long-term use.

Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claimed utility model.
