Description

Technical Field

[0001] The present invention relates to the technical field of spring processing, in particular to a wire feeding device for spring processing. Background Art

[0002] A spring is a mechanical part that uses elasticity to work. Parts made of elastic materials deform under the action of external force and return to their original shape after the external force is removed. They are widely used in manufacturing and various industrial fields.

[0003] Currently, the patent announcement number "CN110625043B" has been published, which discloses a wire feeding device for spring processing, including a support leg, a frame, a wire wheel, a wire wheel fixing mechanism, a wire walking mechanism, a correction wheel and an air control device. The setting of the wire wheel fixing mechanism of the main body of the spring processing wire feeding device realizes the lifting of the wire wheel, and the position height can be controlled at will to ensure that the outlet wire is level with the frame, and prevents the phenomenon of bending due to the formation of a certain angle before entering the wire walking mechanism. The setting of the wire walking mechanism ensures the smoothness of the wire walking and prevents the phenomenon of bending because the height of the wire wheel outlet wire is consistent with the height of the wire roller inlet wire. The setting of the air control device realizes the rising or falling of the wire wheel fixing mechanism, which makes the installation and position adjustment of the wire wheel very convenient, effectively reduces the labor intensity and improves the installation efficiency.

[0004] As can be seen from the main body of the wire feeding device for spring processing proposed above, although the lifting of the wire wheel and the setting of the wire feeding mechanism are used to avoid bending of the wire during movement, after specific use and comparison with existing mature technologies, the following defects still exist:

[0005] 1. First, during the wire feeding process, if the processing part is broken, the feed roller at the feeding end will still rotate and feed the wire under the action of inertia. At this time, since the feeding end is far away from the processing part, the wire will still bend, which will cause the parameters of the spring to not meet the requirements during subsequent manufacturing. In addition, the bent wire will not be able to maintain elasticity, rebound force and strength, which will lead to quality problems, thus affecting the service life and safety performance of the spring.

[0006] 2. Secondly, during the wire feeding process, if the burrs on the spring surface are not processed, the burrs may cause scratches and wear on the spring surface, reducing the durability and service life of the spring. At the same time, the spring surface may become rough, increasing the friction between the spring and other components, which may lead to problems such as jamming, affecting the normal operation and safety performance of the spring. If burrs are found on the wire surface during the wire feeding process, the wire feeding step needs to be stopped to grind the wire, which not only wastes manpower but also greatly reduces processing efficiency.

[0007] 3. After the steel wire is transported to the processing place, due to the size of the transportation groove being larger than that of the steel wire in order to adapt to most sizes of the steel wire, although the steel wire is limited at the front end of the wire feeding, when the steel wire enters the processing port, if the steel wire cannot accurately enter the processing port due to deviation, the sharp end face of the steel wire may be inserted into the processing surface, which needs to be manually leveled by the operator, thereby reducing the processing efficiency, and if the operator manually levels the direction of the sharp end face of the steel wire during wire feeding, due to the fast wire feeding speed, the operator's hand may be cut, thereby causing hidden dangers.

[0008] Therefore, the spring processing wire feeding device is proposed to make up for and improve the shortcomings of the prior art. SUMMARY

[0009] In view of the existing technology that avoids the bending of the steel wire during wire feeding due to pushing, the spring processing wire feeding device can effectively solve the technical problem of the bending of the steel wire during wire feeding due to pushing.

[0010] To achieve the above purpose, the following technical solutions are used:

A hollow grinding block is fixedly mounted on one end of the support rod away from the supporting platform. A spring rod is fixedly mounted on the bottom wall of the hollow grinding block. An arc-shaped grinding block is fixedly mounted on the top of the spring rod. The hollow grinding block is arranged inside the guide groove. The spring body of the spring rod is fixedly mounted on the bottom end of the supporting plate.

[0015] The limiting component includes a telescopic rod, a support plate is fixedly installed at the bottom end of the telescopic rod, and a cross plate is fixedly installed at the front and rear ends of the support plate. A push rod is slidably connected to the inside of the cross plate, and a connecting rod is hinged at the top end of the push rod. The front and rear sides of the bottom end of the support plate are rotatably connected to a rotating plate, and the top end of the rotating plate is provided with an arc groove;

[0016] The guide component includes a processing table, which is fixedly installed at the right end of the workbench, and an upper limit plate is fixedly installed at one end of the processing table close to the workbench, and side limit plates are fixedly installed at both the front and rear ends of the bottom end of the upper limit plate. The upper limit plate is slidably connected to a sliding rod, and a driven plate is fixedly installed at the bottom end of the sliding rod. A lever is hinged on the surface of the sliding rod, and a push rod is hinged on the end of the lever away from the sliding rod, and a push ring is fixedly installed at the bottom end of the push rod.

[0017] Preferably, there are two telescopic rods symmetrically installed on the left and right sides of the top of the support plate. The two telescopic rods provide stable support for the support plate. The bottom end of the push rod is slidably connected to the inside of the arc groove, and when the push rod rotates, it pushes the rotating plate to rotate.

[0018] Preferably, there are four supporting bent rods, and the upper ends of the four supporting bent rods are slidingly connected to the two side grooves respectively. The supporting bent rods are fixedly installed on the side wall at one end inside the side groove and the end of the pressure spring away from the inner wall of the side groove.

[0019] Preferably, the left and right sides of the bottom end of the supporting platform are fixedly mounted to the top ends of the two telescopic rods respectively, the bottom end of the slider is hinged to the top end of the connecting rod, the rotating rod is located above the limit sleeve, and the limit sleeve limits the extreme position of the rotating rod that can be rotated downward, one end of the pull rope is fixedly mounted on the top end of the supporting platform, and the connection between the pull rope and the supporting platform is located between the two connecting rods, and the other end of the pull rope passes through the two rotating sleeves and is fixedly mounted on the top end of the slider.

[0021] Compared with the known public technology, the technical solution provided by the present invention has the following beneficial effects:

[0022] 1. This invention utilizes a rotating rod to pull the wire as it rotates, while two rotating plates periodically clamp the wire, further pushing it. This shifts the wire from being pulled to being pushed. After the wire's processing section stops, the contact point with the wire is close to the processing section, preventing the wire from bending. Furthermore, the two rotating plates use friction to clamp the wire. When the wire's end face is restrained by an emergency stop, the clamping point closest to the end face releases from the rotating plates, preventing further wire movement. This further prevents wire bending.

[0023] 2. This invention utilizes the reciprocating left and right movement of the carrier platform to drive the hollow grinding block and the curved grinding block to grind the surface of the steel wire. This grinding process does not require additional power, reducing energy consumption. The polished steel wire surface is free of burrs, thus avoiding subsequent problems with spring quality or safety issues caused by burrs on the wire surface.

[0024] 3. This invention utilizes two side limit plates and an upper limit plate to guide the transported wire. A push ring then compresses any raised areas of the wire, preventing the wire end from warping and preventing it from accurately entering the processing area. If the sharp end of the wire is misaligned with the processing opening and inserted into the processing surface, the push ring's pressure will free the end of the wire spring from the processing surface, allowing for further guidance of the wire into the processing opening. This process eliminates the need for manual guidance by the operator, preventing the risk of scratches on the sharp end of the wire. BRIEF DESCRIPTION OF THE DRAWINGS

The spring body of the spring rod 53 is fixedly mounted on the bottom end of the supporting plate 42. An arc-shaped grinding block 54 is fixedly mounted on the top of the spring rod 53.

The interior of the upper limit plate 62 is slidably connected to a sliding rod 64, and a driven plate 65 is fixedly mounted on the bottom end of the sliding rod 64. A lever 66 is hinged on the surface of the sliding rod 64, and a push rod 67 is hinged on the end of the lever 66 away from the sliding rod 64. A push ring 68 is fixedly mounted on the bottom end of the push rod 67, and the bottom ends of the push rod 67 are respectively fixedly mounted on the inner walls of the front and rear ends of the guide groove 12, and the sliding rod 64 and the push rod 67 both pass through the upper and lower ends of the upper limit plate 62, and the bottom end of the support of the lever 66 is fixedly mounted on the top of the upper limit plate 62.

[0049] The complete working principle of the above embodiment is as follows:

[0050] First, pass the steel wire through the guide block 13 and place it inside the guide groove 12. Then pass the steel wire through the hollow grinding block 52 and place it on the top of the arc-shaped grinding block 54. At this time, the arc-shaped grinding block 54 pushes the steel wire against the top wall of the hollow grinding block 52 under the action of the elastic force of the spring rod 53.

[0051] The motor connected to the rotating rod 21 is driven to rotate the rotating rod 21. At this time, the rotating rod 21 can initially drive the steel wire to move to the right in the horizontal direction through the friction with the steel wire. During the rotation of the rotating rod 21, the side wheel 22 is driven to rotate, and the side wheel 22 drives the push block 24 to rotate. Then the push block 24 pushes the rotating rod 307 away from one end of the supporting platform 302. At this time, the rotating rod 307 is pushed to the right, so the rotating rod 307 drives the supporting platform 302 to move to the right, and the rotating rod 307 itself will also swing slightly until the push block 24 rotates to the bottom end of the rotating rod 307 and the supporting platform 302 moves to the right. During the rightward movement, the supporting bent rod 301 moves inside the side groove 305 and compresses the pressure spring 306. When the carrying platform 302 moves, the slider 304 is driven to move. At the same time, the carrying platform 302 also pulls the pull rope 311. At this time, the end of the pull rope 311 connected to the carrying platform 302 is pulled, thereby pulling the other end of the pull rope 311 that passes through the rotating sleeve 310 and connected to the slider 304. At this time, the slider 304 is pulled to move rightward inside the slide groove 303. Therefore, at this time, the slider 304 moves rightward inside the slide groove 303 as the carrying platform 302 moves rightward.

[0052] When the slider 304 moves to the right inside the slide groove 303, it pushes the connecting rod 45, so that the connecting rod 45 pushes the hinged push rod 44 to slide downward inside the cross plate 43. At this time, the bottom end of the push rod 44 slides downward inside the arc groove 47. As the bottom end of the push rod 44 slides downward to the bottom of the arc groove 47, the push rod 44 is still pushed downward by the connecting rod 45, so the push rod 44 will push the rotating plate 46 to rotate downward. At this time, the bottom ends of the two rotating plates 46 rotate in the direction of approaching each other, thereby clamping the surface of the steel wire. At the same time, the rotating plate 46 will also press the steel wire downward to increase the friction between the steel wire and the rotating rod 21, and at this time the supporting platform 302 is also moving to the right, so the carrying platform 302 will drive the rotating plate 46 to move to the right, and the rotating plate 46 will pull the steel wire to move to the right and be transported. Since the distance between the processing table 61 and the rotating plate 46 is closer than the distance between the processing table 61 and the guide block 13, when subjected to the same pressure, the lever arm with a shorter bending distance is also shorter, so the ability to resist bending is also stronger, and the shorter bending distance only requires a smaller bending radius at the same bending angle, so that the force on the steel wire is more concentrated and it is not easy to bend. Therefore, when the position of the end face of the steel wire on the processing table 61 is limited due to the emergency stop, the length of the steel wire pushed at this time is shorter and will not bend.

[0053] When the lever 307 is rotated to the bottom end and contacts the limit sleeve 308, the lever 307 can no longer rotate counterclockwise, and the push block 24 continues to push the lever 307. The lever 307 rotates clockwise and disengages from the push block 24. At this time, the support platform 302 is no longer pushed by the lever 307. Therefore, the support platform 302 moves to the left under the action of the restoring force of the pressure spring 306. The slider 304 also moves to the left under the action of the return spring, causing the two rotating plates 46 to release the wire. After that, the side wheel 22 continues to rotate one circle, causing the push block 24 to push the lever 307 again, and the rotating plate 46 pulls the wire to move again, thereby pulling the wire back and forth.

[0054] During the reciprocating left and right movement of the carrier 302, the carrier 302 drives the support rods 51 at the left and right ends to move back and forth. At this time, the support rods 51 drive the hollow grinding blocks 52 and the arc-shaped grinding blocks 54 to move back and forth. The hollow grinding blocks 52 and the arc-shaped grinding blocks 54 continuously grind the surface of the wire as they move. Since the grinding is carried out during the feeding process, there is no need to stop the equipment to reduce processing efficiency, and no additional equipment is required for driving, thereby reducing manpower and energy consumption.

[0055] When the steel wire is conveyed inside the guide groove 12 to a position close to the processing table 61, the steel wire will first enter between the two side limit plates 63. At this time, if the end face of the steel wire is not tilted, it will directly enter the processing port. However, if the end face of the steel wire is tilted, the end face of the steel wire will abut against the bottom end of the driven plate 65. Therefore, the bottom end of the driven plate 65 is pushed upward by the steel wire, so that the driven plate 65 drives the sliding rod 64 to move upward. At this time, the sliding rod 64 drives the lever 66 to rotate, thereby driving the push rod 67 to move downward. The pushing rod 67 will push the pushing ring 68 to move downward, and the pushing ring 68 will push the surface of the side of the steel wire close to the end face, thereby pushing the end face of the steel wire downward for a slight distance, and then the pushed end face of the steel wire will continue to move and enter the processing port. Under the push of the pushing ring 68, the sharp end face of the steel wire will not be inserted into the surface of the processing table 61 or the driven plate 65, and no manual guidance is required. Not only does it improve the transportation efficiency, but the operator does not need to touch the sharp end face of the steel wire and avoid the hidden danger of scratching his hands.

[0056] The above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit the same. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the aforementioned embodiments, or make equivalent replacements for some of the technical features therein. However, these modifications or replacements will not cause the essence of the corresponding technical solutions to deviate from the spirit and scope of the technical solutions of the various embodiments of the present invention.
