Description

Technical Field

[0001] This utility model relates to a feeding mechanism, and more particularly to a spring processing feeding mechanism applied in the field of spring processing. Background Technology

[0002] A spring is a mechanical part that works by utilizing elasticity. 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 generally made of spring steel. There are many types of springs. According to their shape, they mainly include helical springs, spiral springs, leaf springs, and special-shaped springs. The core of spring processing is to feed the metal wire into the processing device (such as a spring coiling machine) and shape it through bending, coiling and other actions.

[0003] In spring processing equipment, the wire feeding wheel is the core component of the wire feeding device. Its function directly affects the stability of the metal wire feeding and the processing quality. The groove width of existing wire feeding wheels is mostly fixed. However, when processing springs of different sizes, the diameter of the metal wire used is not the same. This may cause the groove of the wire feeding wheel to be too large or too small relative to the metal wire. If the groove is too large, the metal wire may wobble in the groove and easily fall off. If the groove is too small, it may increase the friction between the metal wire and the groove, scratching the surface of the metal wire, thus affecting the subsequent processing of the spring. Utility Model Content

[0004] The technical problem that this utility model aims to solve in view of the above-mentioned prior art is that the grooves of existing wire feeding wheels are mostly of fixed width, which cannot be adapted to metal wires of different sizes. Mismatched grooves can cause metal wires to fall off or increase friction with the grooves, thereby affecting the subsequent processing of springs.

[0005] To solve the above problems, this utility model provides a spring processing feeding mechanism, including an L-shaped mounting plate. The front end of the mounting plate is provided with a wire feeding wheel and a straightening frame. The straightening frame is located to the right of the wire feeding wheel. The wire feeding wheel includes a support block fixedly connected to the upper end of the mounting plate and a motor fixedly connected to the rear end of the mounting plate. The upper end of the support block is fixedly connected to a mounting frame. The output end of the motor movably passes through the mounting plate and is fixedly connected to a mounting shaft. The front end of the mounting shaft rotatably passes through the mounting frame. The outer surface of the mounting shaft is respectively fixedly fitted with a fixed ring and a rotating ring. The fixed ring is located behind the rotating ring, and the front end of the fixed ring is fixedly connected to a positioning ring. The outer surface of the positioning ring is slidably fitted with an adjusting ring. The front ends of the adjusting ring and the rotating ring are jointly fixedly connected to multiple U-shaped rods. The outer surface of the mounting shaft is chiseled with multiple grooves, and an adjusting block is provided inside the mounting shaft. The outer surface of the adjusting block is fixedly connected with multiple protrusions. The protrusions movably pass through adjacent grooves and are fixedly connected to the inner wall of the rotating ring. A screw is rotatably connected to the circular inner wall of the mounting shaft, and the front end of the screw threadedly passes through the adjusting block.

[0006] In the above-mentioned spring processing feeding mechanism, compared with the existing wire feeding wheel with a fixed groove width, this application can adjust the groove width of the wire feeding wheel so that the wire feeding wheel can match the metal wires of different diameters, thereby effectively avoiding the metal wires from falling off or deforming due to excessive friction.

[0007] As a further improvement of this application, the straightening frame includes two mounting strips located at the front end of the mounting plate. The lower mounting strip is fixedly connected to the mounting plate, and the upper mounting strip is slidably connected to the mounting plate. Multiple straightening rollers are mounted on the front end of the mounting strips. Two screw rods are rotatably connected to the upper end of the lower mounting strip. The upper ends of the screw rods are threaded through the mounting strips, and a pulley set is commonly fitted around the two screw rods.

[0008] As a further improvement of this application, a plurality of compression springs are fixedly connected between the fixed ring and the moving ring, and the plurality of compression springs and the plurality of U-shaped rods are arranged in a ring array around the central axis of the mounting shaft.

[0009] As a further improvement of this application, the outer ring surface of the moving ring is in contact with the inner wall of the positioning ring, the inner ring surface of the adjusting ring is in contact with the outer surface of the positioning ring, and the front end of the adjusting ring is located inside multiple U-shaped rods.

[0010] As a further improvement of this application, the outer surface of the adjusting block contacts the inner wall of the mounting shaft, and the front end of the screw is located at the front end of the mounting bracket.

[0011] As another improvement of this application, the front end of the mounting plate is chiseled with a receiving groove, the inner top wall of the receiving groove is fixedly connected with a compression spring two, the lower end of the compression spring two is fixedly connected with a sliding plate, the inner wall of the receiving groove is fixedly connected with a sliding rod, the upper end of the sliding rod moves through the sliding plate and the compression spring two in sequence, the lower end of the sliding plate is fixedly connected with a mounting rod, and the lower end of the mounting rod is fixedly connected with an anti-detachment plate.

[0012] As a further improvement to this application, the receiving groove is located above the wire feeding wheel, the longitudinal section of the anti-detachment plate is arc-shaped, and the outer surfaces of the fixed ring and the adjusting ring are both in contact with the lower end of the anti-detachment plate.

[0013] In summary, in practical applications, the metal wire is coiled around the surface of the wire feeding wheel and passes through the straightening frame, thus entering the spring processing device for processing and shaping. When feeding metal wires of different diameters, the first screw can be rotated to move the adjusting block back and forth, thereby driving the ring to move back and forth through the protrusion. Multiple U-shaped rods can also drive the adjusting ring to move back and forth, changing the distance between the adjusting ring and the fixed ring, thereby adjusting the groove width of the wire feeding wheel, so that the wire feeding wheel matches the metal wires of different diameters, thus effectively preventing the metal wires from falling off or deforming due to excessive friction. At the same time, the second screw can be rotated to move the upper mounting strip upward, thereby adjusting the distance between the two mounting strips, which facilitates the feeding and straightening of metal wires of different diameters.

Detailed Implementation

[0024] The two embodiments of this application will be described in detail below with reference to the accompanying drawings.

[0025] First implementation method:

[0026] Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 and Figure 6The following is shown: A spring processing feeding mechanism includes an L-shaped mounting plate 1. The front end of the mounting plate 1 is provided with a wire feeding wheel 2 and a straightening frame 3. The straightening frame 3 is located to the right of the wire feeding wheel 2. An external winding machine feeds the metal wire, which coils around the surface of the wire feeding wheel 2, passes through the straightening frame 3, and then enters the spring processing device for processing and shaping. The wire feeding wheel 2 includes a support block 201 fixedly connected to the upper end of the mounting plate 1 and a motor 202 fixedly connected to the rear end of the mounting plate 1. Those skilled in the art can select a suitable model of motor 202 according to actual needs, such as Y2-63M1-2-0.18KW. The upper end of the support block 201 is fixedly connected to the mounting frame 203, and the output end of the motor 202 movably passes through it. Mounting plate 1 is fixedly connected to mounting shaft 204. Motor 202 can drive mounting shaft 204 to rotate. The front end of mounting shaft 204 rotates through mounting bracket 203. Fixed ring 205 and rotating ring 206 are fixedly and rotatably sleeved on the outer surface of mounting shaft 204, respectively. Fixed ring 205 is located behind rotating ring 206, and positioning ring 207 is fixedly connected to the front end of fixed ring 205. Adjusting ring 208 is slidably sleeved on the outer surface of positioning ring 207. Multiple U-shaped rods 209 are fixedly connected to the front ends of adjusting ring 208 and rotating ring 206. Multiple sliding grooves 210 are chiseled on the outer surface of mounting shaft 204. Sliding grooves 210 can limit the movement of protrusion 212, forcing protrusion 212 to move only back and forth. An adjusting block 211 is provided inside. Multiple protrusions 212 are fixedly connected to the outer surface of the adjusting block 211. The protrusions 212 movably pass through the adjacent sliding groove 210 and are fixedly connected to the inner wall of the moving ring 206. A screw 213 is rotatably connected to the circular inner wall of the mounting shaft 204. The front end of the screw 213 is threaded through the adjusting block 211. Rotating the screw 213 causes the adjusting block 211 to move back and forth, and the multiple protrusions 212 slide within the sliding groove 210. This causes the ring 206 to move back and forth via the protrusions 212. Meanwhile, multiple U-shaped rods 209 can drive the adjusting ring 208 to move back and forth, changing the distance between the adjusting ring 208 and the fixed ring 205, thereby adjusting the groove width of the wire feeding wheel 2. The diameter of the metal wire is matched. Multiple compression springs 214 are fixedly connected between the fixed ring 205 and the moving ring 206. The multiple compression springs 214 and multiple U-shaped rods 209 are arranged in a ring array around the central axis of the mounting shaft 204. The outer ring surface of the moving ring 206 is in contact with the inner wall of the positioning ring 207. The inner ring surface of the adjusting ring 208 is in contact with the outer surface of the positioning ring 207. The front end of the adjusting ring 208 is located inside the multiple U-shaped rods 209. The U-shaped rods 209 can make the adjusting ring 208 and the moving ring 206 move synchronously. The outer surface of the adjusting block 211 is in contact with the inner wall of the mounting shaft 204. The front end of the screw 213 is located at the front end of the mounting bracket 203 for easy use by the operator. Point A in the figure is the metal wire.

[0027] Figure 1 , Figure 2and Figure 7 The straightening frame 3 includes two mounting strips 301 located at the front end of the mounting plate 1. The lower mounting strip 301 is fixedly connected to the mounting plate 1, and the upper mounting strip 301 is slidably connected to the mounting plate 1. Multiple straightening rollers 302 are installed at the front end of the mounting strip 301. Two screw rods 303 are rotatably connected to the upper end of the lower mounting strip 301. The upper end of the screw rods 303 is threaded through the mounting strip 301. A pulley set 304 is fitted around the two screw rods 303. By rotating the screw rods 303, the upper mounting strip 301 can be moved upward, thereby adjusting the distance between the two mounting strips 301. This facilitates the straightening of metal wires of different diameters. The pulley set 304 can drive the two screw rods 303 to rotate synchronously, thus facilitating the use by the operator.

[0028] During feeding, the metal wire is conveyed by an external winding machine. The metal wire is coiled on the surface of the wire feeding wheel 2 and passes through the straightening frame 3 before entering the spring processing device for processing and shaping. When feeding metal wires of different diameters, the screw 213 can be rotated to move the adjusting block 211 back and forth, thereby driving the ring 206 back and forth through the protrusion 212. The multiple U-shaped rods 209 can also drive the adjusting ring 208 back and forth, changing the distance between the adjusting ring 208 and the fixed ring 205. This allows the groove width of the wire feeding wheel 2 to be adjusted, so that the wire feeding wheel 2 can match the metal wires of different diameters, thus effectively preventing the metal wires from falling off or deforming due to excessive friction.

[0029] Second implementation method:

[0030] This embodiment adds a receiving groove 4, a compression spring 5, a sliding plate 6, a sliding rod 7, and an anti-detachment plate 8 to the first embodiment, while the rest remains the same as the first embodiment.

[0031] Figure 8 As shown: The front end of the mounting plate 1 has a receiving groove 4. A compression spring 5 is fixedly connected to the inner top wall of the receiving groove 4. A sliding plate 6 is fixedly connected to the lower end of the compression spring 5. A sliding rod 7 is fixedly connected to the inner wall of the receiving groove 4. The sliding plate 6 can move on the sliding rod 7, thereby pushing the compression spring 5 to compress upward. The upper end of the sliding rod 7 moves through the sliding plate 6 and the compression spring 5 in sequence. An installation rod is fixedly connected to the lower end of the sliding plate 6. An anti-detachment plate 8 is fixedly connected to the lower end of the installation rod. The receiving groove 4 is located above the wire feeding wheel 2. The longitudinal section of the anti-detachment plate 8 is arc-shaped. The outer surfaces of the fixed ring 205 and the adjusting ring 208 are both in contact with the lower end of the anti-detachment plate 8. The anti-detachment plate 8 can protect the upper end of the wire feeding wheel 2 and effectively prevent the metal wire from coming off.

[0032] When the metal wire is coiled around the surface of the wire feeding wheel 2, the anti-detachment plate 8 can be pushed upward, causing the mounting rod and the slide plate 6 to move upward. The compression spring 2 5 contracts upward, and after the metal wire is coiled inside the wire feeding wheel 2, the anti-detachment plate 8 can be released, allowing the compression spring 2 5 to return to its original position. The anti-detachment plate 8 is in contact with the surface of the wire feeding wheel 2, and can protect the upper end of the wire feeding wheel 2 during the rotation of the wire feeding wheel 2, effectively preventing the metal wire from coming off.

[0033] In light of current practical needs, the above-described embodiments adopted in this application are not limited to this scope of protection. Any changes made within the scope of knowledge possessed by those skilled in the art without departing from the concept of this application still fall within the protection scope of this utility model.
