Description

Technical Field

[0001] This utility model relates to the field of spring machine technology, and more specifically to a spring machine winding mechanism that can rotate at least 360 degrees. Background Technology

[0002] A spring machine is an automated processing equipment used to produce various types of springs (such as compression springs, tension springs, torsion springs, forming springs, etc.). It uses a program-controlled servo motor, cam mechanism, or slide rail system to drive actuators for wire feeding, winding, bending, and shearing, precisely shaping metal wire to produce the desired spring structure.

[0003] The following problems exist in the current market: After the safety collision structure is set, the rotation angle of the current spring machine turning mechanism is less than 360 degrees, which means that some process stations need to be treated differently in the design, thereby affecting the production efficiency and even the processing yield.

[0004] The technical problem to be solved by this utility model is to provide a spring machine winding mechanism that has safety collision protection and can rotate at least 360 degrees. Utility Model Content

[0005] The technical problem this invention addresses is: providing a spring-loaded wire-turning mechanism with safety features and at least 360-degree rotation capability; the mechanism uses a tail shaft mounted on a support plate to thread and rotate the metal wire, with the tail shaft reciprocating under the drive mechanism; one end of the tail shaft is fixed with a stop block, and when the tail shaft rotates to the position of the reset block, the stop block rotates 360 degrees under the drive mechanism, collides with the reset block, and continues to rotate 1 to 10 degrees, triggering the reset spring to pull back the reset block for automatic reset, thus forming a limit control process. The reset block not only has a reset function but also serves as a safety protection mechanism. In the event of a malfunction in the drive mechanism or a failure in the control system causing the tail shaft to rotate continuously, it physically prevents the tail shaft from rotating without restriction, thereby preventing equipment damage or safety accidents and improving the overall stability and safety of the machine.

[0006] A spring-loaded wire-carrying mechanism capable of rotating at least 360 degrees includes a support plate with a tail shaft for passing through a metal wire. The tail shaft is rotatably connected to the support plate. A drive mechanism is provided to drive the tail shaft to rotate. A stop block is fixedly connected to one side of the tail shaft. A reset block is rotatably connected to the support plate. A reset spring is provided and connected to the reset block. The other end of the reset spring is fixedly connected to the support plate. The drive mechanism drives the tail shaft and the stop block to rotate in both directions. After the stop block rotates one revolution, it collides with the reset block. After the collision, the stop block rotates another 1 to 10 degrees. Then, the drive mechanism drives the tail shaft and the stop block to rotate in the opposite direction, and the reset spring drives the reset block to reset.

[0007] Preferably, the drive mechanism includes a driven wheel connected to the tail shaft; and a driving wheel corresponding to the driven wheel; a belt is wound between the driven wheel and the driving wheel; and a motor is provided to drive the driving wheel to rotate.

[0008] Preferably, the device also includes several upper feed rollers and several lower feed rollers for conveying the metal wire; and both the upper feed rollers and the lower feed rollers are driven to rotate by a motor.

[0009] Preferably, a wedge-shaped protrusion is formed on one side of the impact block; and a protrusion corresponding to the wedge-shaped protrusion is formed on the bottom of the reset block; when the impact block collides with the reset block, the wedge-shaped protrusion collides with the protrusion.

[0010] Preferably, a first limiting post and a second limiting post are provided on one side of the reset block at intervals; and a third limiting post and a fourth limiting post are provided on the other side of the reset block at intervals; thereby limiting the angle of the reset block during rotation.

[0011] Preferably, the first limiting post, the second limiting post, the third limiting post, and the fourth limiting post are basically parallel to each other.

[0012] Compared with existing technologies, the beneficial effects of this utility model are as follows: This utility model features a spring-loaded wire-turning mechanism capable of rotating at least 360 degrees. The metal wire is threaded and rotated via a tail shaft mounted on a support plate. Driven by a drive mechanism, the tail shaft reciprocates in both directions. One end of the tail shaft is fixed with a stop block. When the tail shaft rotates to the position of the reset block, the stop block rotates 360 degrees under the drive mechanism, collides with the reset block, and continues to rotate 1 to 10 degrees. This triggers the reset spring to pull back the reset block, achieving automatic reset while simultaneously forming a limit control process. The reset block not only has a reset function but also serves as a safety protection mechanism. In the event of a drive mechanism malfunction or control system failure causing the tail shaft to rotate continuously, it physically blocks the unrestricted rotation of the tail shaft, thereby preventing equipment damage or safety accidents and improving the overall stability and safety of the machine.

Detailed Implementation

[0021] The technical solutions in the embodiments of this utility model will be clearly and completely described below. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0022] It should be noted that the terms "first," "second," etc., used in this utility model are used to distinguish similar objects and are not necessarily used to describe a specific order or sequence. It should be understood that such data can be interchanged where appropriate so that the embodiments of this disclosure described herein can be implemented in orders other than those illustrated or described herein. The implementation methods described in the following exemplary embodiments do not represent all implementation methods consistent with this disclosure.

[0023] Please see Figures 1-5 In this embodiment of the present invention, a spring-loaded wire-turning mechanism capable of rotating at least 360 degrees includes a support plate 1; a tail shaft 2 for passing through a metal wire 12 is provided on the support plate 1; the tail shaft 2 is rotatably connected to the support plate 1; a drive mechanism for driving the tail shaft 2 to rotate is provided; a collision block 3 is fixedly connected to one side of the tail shaft 2; a reset block 4 is rotatably connected to the support plate 1; a reset spring 5 is provided connected to the reset block 4; and the other end of the reset spring 5 is fixedly connected to the support plate 1. The drive mechanism drives the tail shaft 2 and the collision block 3 to rotate in both directions. After the collision block 3 rotates one revolution, it collides with the reset block 4. After the collision, the collision block 3 rotates 1 to 10 degrees (the actual maximum rotation is 370 degrees). Then, the drive mechanism drives the tail shaft 2 and the collision block 3 to rotate in the opposite direction, and the reset spring 5 drives the reset block 4 to reset.

[0024] Specifically, the spring-loaded wire-turning mechanism, capable of rotating at least 360 degrees, uses a tail shaft 2 mounted on the support plate 1 to thread and rotate the metal wire 12. The tail shaft 2 reciprocates in both directions under the drive mechanism. One end is fixed with a stop block 3. When the tail shaft 2 rotates to the position of the reset block 4, the stop block 3 rotates 360 degrees under the drive mechanism, collides with the reset block 4, and continues to rotate 1 to 10 degrees. This triggers the reset spring 5 to pull back the reset block 4, achieving automatic reset and simultaneously forming a limit control process. The reset block 4 not only has a reset function but also serves as a safety protection mechanism. In the event of a malfunction in the drive mechanism or a failure in the control system causing the tail shaft 2 to rotate continuously, it physically prevents the tail shaft 2 from rotating without restriction, thus preventing equipment damage or safety accidents and improving the overall stability and safety of the machine. The reset spring 5 can be connected to the top of the reset block 4.

[0025] Furthermore, the drive mechanism includes a driven wheel 6 connected to the tail shaft 2; and a driving wheel 7 corresponding to the driven wheel 6; and a belt 8 is wound between the driven wheel 6 and the driving wheel 7; and a drive motor 9 is provided to drive the driving wheel 7 to rotate.

[0026] Specifically, the drive mechanism adopts a belt-driven 8-pulley transmission structure, including a driven pulley 6 connected to the tail shaft 2 and a corresponding driving pulley 7. The two are connected by a belt 8 to achieve power transmission. The driving pulley 7 is driven to rotate by a drive motor 9, thereby driving the driven pulley 6 and the tail shaft 2 to rotate synchronously through the belt 8. This structure has high transmission efficiency, stable operation, and can effectively reduce shock and vibration, extending the mechanical life.

[0027] Furthermore, there are several upper feeding rollers 10 and several lower feeding rollers 11 for conveying the metal wire 12; and the several upper feeding rollers 10 and several lower feeding rollers 11 are all driven to rotate by a motor (not shown, for example, the feeding rollers are directly driven by the motor or multiple feeding rollers are driven simultaneously by a motor gear chain).

[0028] Specifically, the mechanism is equipped with several upper feeding rollers 10 and several lower feeding rollers 11, which work together to clamp and convey the metal wire 12. The upper and lower rollers apply uniform pressure to the metal wire 12 to achieve a stable and precise feeding process. All feeding rollers are driven by motors to rotate, and can achieve continuous or intermittent feeding as needed, with good speed control capabilities.

[0029] Furthermore, a wedge-shaped protrusion 13 is formed on one side of the impact block 3; and a protrusion 14 corresponding to the wedge-shaped protrusion 13 is formed on the bottom of the reset block 4; when the impact block 3 collides with the reset block 4, the wedge-shaped protrusion 13 and the protrusion 14 collide.

[0030] Specifically, one side of the impact block 3 has a wedge-shaped protrusion 13, and the bottom of the reset block 4 has a corresponding protrusion 14. The two collide precisely after the tail shaft 2 rotates to a specified angle. This wedge-shaped structure design features strong guidance and concentrated contact surfaces, which not only helps to achieve a stable and controllable trigger point but also effectively improves the mechanical response sensitivity and positioning accuracy during the collision process, avoiding slippage or misalignment caused by irregular impact surfaces. Simultaneously, the wedge-shaped structure also enhances the force transmission efficiency during the impact process, improving the reliability of the reset action and the overall structural durability.

[0031] Furthermore, a first limiting post 15 and a second limiting post 16 are provided at intervals on one side of the reset block 4; and a third limiting post 17 and a fourth limiting post 18 are provided at intervals on the other side of the reset block 4; thereby limiting the angle of the reset block 4 during rotation.

[0032] Specifically, the reset block 4 has a first limiting post 15 and a second limiting post 16 spaced apart on one side, and a third limiting post 17 and a fourth limiting post 18 spaced apart on the other side. These four limiting posts together constitute a physical limiting structure for the rotation range of the reset block 4. During the rotation of the reset block 4, the limiting posts effectively restrict its swing angle, preventing excessive rotation or offset, thereby ensuring the accuracy and repeatability of the reset action. They also serve a protective function, preventing mechanical interference or damage to the reset block 4 due to abnormal force, thus improving the stability and service life of the overall mechanism.

[0033] Furthermore, the first limiting post 15, the second limiting post 16, the third limiting post 17, and the fourth limiting post 18 are basically parallel to each other.

[0034] Specifically, the first limiting post 15, the second limiting post 16, the third limiting post 17, and the fourth limiting post 18 are arranged in a basically parallel manner, allowing the reset block 4 to swing stably within a specific angle range under the joint constraint of the limiting structures on both sides. This parallel arrangement not only helps to achieve symmetrical control of the movement path of the reset block 4, ensuring balanced force and smooth movement, but also improves the limiting accuracy, avoids eccentric swinging or jamming, and further enhances the reliability and consistency of the mechanism in long-term operation.

[0035] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered exemplary and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within this invention.
