Description

Technical Field

[0001] This utility model relates to the technical field of wire feeding mechanisms, specifically a spring-loaded wire feeding mechanism with adaptive tension compensation. Background Technology

[0002] A spring machine, also known as a coiling spring machine, is a specialized piece of equipment used for the production and processing of various springs. A spring machine mainly consists of a straightening mechanism, a diameter changing mechanism, a pitch changing mechanism, a wire feeding mechanism, and a cutting mechanism. The wire feeding mechanism is an indispensable part of the spring machine. It is mainly driven by a motor-driven pressure wheel, which presses the steel wire and then rotates to feed the wire. Automatic spring forming machines are equipped with a wire feeding wheel transmission mechanism to continuously and forcibly feed the metal wire into the winding mechanism for spring forming.

[0003] Existing spring wire feeding mechanisms with adaptive tension compensation often experience loosening of the spring wire during transport due to insufficient tension. Excessive looseness can cause the spring wire to twist and tangle, reducing the conveying efficiency. Furthermore, the machine needs to be stopped to clear the tangles, further decreasing the wire feeding efficiency. Utility Model Content

[0004] (a) Technical problems to be solved

[0005] To address the shortcomings of existing technologies, this utility model provides a spring wire feeding mechanism with adaptive tension compensation. This solves the problem that when feeding spring wire, insufficient tension causes the spring wire to loosen during the feeding process. Excessive looseness can lead to twisting and tangling of the spring wire, thereby reducing the feeding efficiency. Furthermore, when tangling occurs, the machine needs to be stopped to clear the tangles, further reducing the feeding efficiency.

[0006] (II) Technical Solution

[0007] To achieve the above objectives, this utility model provides the following technical solution: a spring machine wire feeding mechanism with adaptive tension compensation, comprising a base and a side plate. The side plate is vertically fixedly connected to the top of the base. A winding mechanism is fixedly connected to one side of the top of the base. Spring wire is wound on the surface of the winding mechanism. A guide mechanism is provided on the surface of the side plate, and multiple guide mechanisms are provided. A tension compensation mechanism is provided on the front of the side plate, and two sets of tension compensation mechanisms are provided. The two sets of tension compensation mechanisms are centrally symmetrically distributed and each set of tension compensation mechanisms is located between two of the guide mechanisms. A controller is fixedly connected to one side of the side plate.

[0008] In this invention, a winding mechanism is used to wind the spring wire for unwinding preparation. Then, the spring wire passes through the first guide mechanism, then through the tension compensation mechanism, and finally through the remaining guide mechanisms. The controller starts the guide mechanism to work, so that the spring wire on its surface can move through. The tension compensation mechanism tensions the spring wire to prevent it from loosening.

[0009] Preferably, the tension compensation mechanism includes a fixing plate, which is fixedly connected to the front of the side plate, and the fixing plate is arranged parallel to the spring line.

[0010] Preferably, a sleeve is fixedly connected to the bottom of the fixing plate, a sleeve rod is sleeved inside the sleeve, the bottom end of the sleeve rod passes through the inner wall of the sleeve and is rotatably connected to a rotating plate, and a retaining spring is elastically connected between the inner wall of the sleeve and the sleeve rod.

[0011] Preferably, a V-shaped plate is rotatably connected to the bottom of the rotating plate, the included angle of the V-shaped plate is a right angle, and guide rollers are rotatably connected to both ends of the bottom of the V-shaped plate, and these guide rollers intersect with the guide rollers on another tension compensation mechanism.

[0012] In this invention, when the spring wire is tensioned by the tension compensation mechanism, the sleeve is first fixed by the fixing plate. Then, the clamping action of the clamping spring causes the upper and lower sleeve rods to press together towards the spring wire. Afterward, the V-shaped plate on the rotating plate drives the guide roller to press the spring wire. Through the clamping action, the curvature of the relatively loose spring wire in the guide roller increases, thereby achieving the purpose of tensioning. When the spring wire is tight, the curvature of the spring wire in the guide roller decreases, thereby achieving the purpose of tension compensation for the spring wire. At the same time, the rotatable rotating plate can increase or decrease the overall curvature of the spring wire between the two mechanisms, thereby further compensating for the tension. By setting up the tension compensation mechanism, the tension on the spring wire can be compensated and adjusted to prevent the spring wire from being too loose and reducing the processing quality of the subsequent springs.

[0013] Preferably, the guiding mechanism includes guide wheels, and there are two guide wheels. A connecting plate is fixedly connected between one end of the two guide wheels, and the spring wire passes between the two guide wheels.

[0014] Preferably, one end of one of the guide wheels is rotatably connected to the surface of the side plate, and the other end of the other guide wheel passes through the side wall of the side plate and is rotatably connected to a motor, the motor being fixedly installed on the back of the side plate.

[0015] In this invention, when the guiding mechanism is working, the starting motor drives one of the guide wheels to rotate. Since the spring wire rolls between the two guide wheels, the other guide wheel rotates and conveys the spring wire. By setting multiple sets of guiding mechanisms, the spring wire can be supported and accurately conveyed to the required position, thus improving the conveying accuracy.

[0016] (III) Beneficial Effects

[0017] This utility model provides a spring-loaded wire feeding mechanism with adaptive tension compensation. It features the following:

[0018] Beneficial effects:

[0019] (I) The spring feeding mechanism with adaptive tension compensation utilizes a tension compensation mechanism to ensure that the upper and lower sleeves are pressed together towards the spring wire by a clamping spring. At the same time, the guide roller presses against the spring wire, increasing the curvature of the loose spring wire in the guide roller, thereby achieving the purpose of tension. By rotating the rotating plate, the overall curvature of the spring wire between the two mechanisms can be increased or decreased, thereby further compensating for the tension. Through the setting of the tension compensation mechanism, the tension on the spring wire can be compensated and adjusted, preventing the spring wire from becoming too loose and tangling, which would reduce the processing quality of subsequent springs. It also reduces the probability of stopping to comb the spring wire and improves the wire feeding efficiency.

[0020] (II) The spring wire feeding mechanism with adaptive tension compensation, through the setting of the guide mechanism, the motor drives one of the guide wheels to rotate. Since the spring wire rolls between the two guide wheels, the other guide wheel rotates and feeds the spring wire. Through the setting of multiple sets of guide mechanisms, the spring wire can be supported and accurately fed to the required position, thus improving the feeding accuracy.

[0027] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0028] See Figures 1-5 This utility model provides a technical solution: a spring wire feeding mechanism with adaptive tension compensation, the structure of which includes a base 1 and a side plate 2. The side plate 2 is vertically fixedly connected to the top of the base 1. A winding mechanism 3 is fixedly connected to one side of the top of the base 1. Spring wire 4 is wound on the surface of the winding mechanism 3. A guide mechanism 5 is provided on the surface of the side plate 2. The number of guide mechanisms 5 is set to multiple. A tension compensation mechanism 6 is provided on the front of the side plate 2. There are two sets of tension compensation mechanisms 6. The two sets of tension compensation mechanisms 6 are centrally symmetrically distributed. Both sets of tension compensation mechanisms 6 are set between two of the guide mechanisms 5. A controller 7 is fixedly connected to one side of the side plate 2. Specifically, the winding mechanism 3 is used to wind the spring wire 4 to prepare for wire feeding. Then, the spring wire 4 passes through the first guide mechanism 5, then through the tension compensation mechanism 6, and finally through the remaining guide mechanisms 5. The controller 7 starts the guide mechanism 5 to work, so that the spring wire 4 on its surface can move through, and the tension compensation mechanism 6 tensions the spring wire 4 to prevent it from loosening.

[0029] The tension compensation mechanism 6 includes a fixing plate 61, which is fixedly connected to the front of the side plate 2 and is arranged parallel to the spring wire 4.

[0030] The bottom of the fixed plate 61 is fixedly connected to a sleeve 62, and a sleeve rod 63 is sleeved inside the sleeve 62. The bottom end of the sleeve rod 63 passes through the inner wall of the sleeve 62 and is rotatably connected to a rotating plate 64. A retaining spring 65 is elastically connected between the inner wall of the sleeve 62 and the sleeve rod 63.

[0031] Among them, the bottom of the rotating plate 64 is rotatably connected to a V-shaped plate 66, the included angle of the V-shaped plate 66 is a right angle, and the bottom ends of the V-shaped plate 66 are rotatably connected to guide rollers 67, which are intersected with the guide rollers 67 on another tension compensation mechanism 6.

[0032] Specifically, when the tension compensation mechanism 6 tensions the spring wire 4, the sleeve 62 is first fixed by the fixing plate 61. Then, the clamping action of the clamping spring 65 causes the upper and lower sleeve rods 63 to press together towards the spring wire 4. After that, the V-shaped plate 66 on the rotating plate 64 drives the guide roller 67 to press against the spring wire 4. Through the clamping action, the curvature of the relatively loose spring wire 4 in the guide roller increases, thereby achieving the purpose of tensioning. When the spring wire 4 is tight, the curvature of the spring wire 4 in the guide roller decreases, thereby achieving the purpose of tension compensation for the spring wire 4. At the same time, the rotatable rotating plate 64 can increase or decrease the overall curvature of the spring wire 4 between the two mechanisms, thereby further compensating for the tension. Through the setting of the tension compensation mechanism 6, the tension on the spring wire 4 can be compensated and adjusted to prevent the spring wire 4 from being too loose and reducing the processing quality of the subsequent spring.

[0033] The guide mechanism 5 includes guide wheels 51, and there are two guide wheels 51. A connecting plate 52 is fixedly connected between one end of the two guide wheels 51, and a spring wire 4 passes between the two guide wheels 51.

[0034] One of the guide wheels 51 has its other end rotatably connected to the surface of the side plate 2, and the other guide wheel 51 has its other end passing through the side wall of the side plate 2 and rotatably connected to a motor 53. The motor 53 is fixedly installed on the back of the side plate 2.

[0035] Specifically, when the guide mechanism 5 is working, the starter motor 53 drives one of the guide wheels 51 to rotate. Since the spring wire 4 rolls between the two guide wheels 51, the other guide wheel 51 rotates and conveys the spring wire 4. Through the multiple sets of guide mechanisms 5, the spring wire 4 can be supported and accurately conveyed to the required position, thus improving the conveying accuracy.
