Description

Technical Field

[0001] This utility model relates to the field of wire processing, and in particular to a simple clamp-type wire feeder for use in a round wire heading machine. Background Technology

[0002] An existing patent concerning wire delivery, authorized publication number CN223292052U, discloses a wire traction mechanism. The specification describes that each circular hole is movably equipped with a bead, and the wire passes through the center of multiple beads. When the wire needs to be delivered, the guide tube is first pushed, and the guide tube moves in the direction of the sleeve. At this time, the wall of the frustum-shaped cavity presses down on the beads, and multiple beads move closer to the wire and squeeze it. At this time, multiple beads together clamp the wire and move a set distance with the guide tube. Then the guide tube is reset. When the guide tube moves back and forth, the force of the inner wall of the guide tube on the beads decreases, and then multiple beads release the wire. After resetting, the guide tube performs the same steps as described above.

[0003] The disadvantages are that the cost is relatively high, and the requirements for the solenoid valve are high when operating at high speed and high frequency for a long time. If the solenoid valve is not sensitive enough, there will be a lag phenomenon. In addition, when multiple balls are clamped together, the wires will leave clamping marks, resulting in defective products. Utility Model Content

[0005] To achieve the above objectives, the technical solution adopted by this utility model is as follows: This utility model provides a simple clamp-type wire feeder for a round wire heading machine, including a base and a wire clamping assembly, the wire clamping assembly being disposed on the base. The wire clamping assembly includes a positioning block, a spring, an upper clamping bar, a lower clamping bar, a first limiting block, and a second limiting block. The positioning block is disposed on the base and has a sliding groove. The upper clamping bar and the lower clamping bar are rotatably disposed in the sliding groove, with the upper clamping bar positioned above the lower clamping bar. The first limiting block and the second limiting block are respectively disposed at both ends of the sliding groove. The first limiting block is located in the moving direction of the upper clamping bar and the lower clamping bar.

The spring has a through hole, the first limiting block is provided with a feeding hole, the second limiting block is provided with a discharging hole, the feeding hole, the through hole and the discharging hole are connected, and the bottom surface of the upper clamping bar and the top surface of the lower clamping bar are used to clamp the wire. The upper clamp and the lower clamp are configured such that when they rotate, they can move away from or closer to each other. When the front end of the wire is pulled, the spring is compressed, and the upper clamp and the lower clamp separate from each other under the action of rotation, which will loosen the wire. After the wire is pulled away to a set length, the wire is no longer pulled, and then the spring is released to its natural state. The upper clamp and the lower clamp rotate in opposite directions to clamp the wire.

[0006] Optionally, the clamping assembly further includes a first adjusting bolt and a second adjusting bolt, wherein the first limiting block is connected to the positioning block via the first adjusting bolt, and the second limiting block is connected to the positioning block via the second adjusting bolt, and the first limiting block and the second limiting block are respectively located at the two axial opening ends of the slide groove.

[0007] Optionally, a recessed platform is provided in the discharge hole, and the spring extends into the discharge hole, with the second end of the spring abutting against the recessed platform.

[0008] Optionally, the wire clamping assembly further includes a first rotating block, a second rotating block, and a third rotating block, which are rotatably disposed within the slide groove. The first rotating block is located above the second rotating block and the third rotating block. The upper clamping strip is disposed on the first rotating block. The second rotating block and the third rotating block are spaced apart at the same height. The lower clamping strip is rotatably connected to the second rotating block and the third rotating block.

[0009] Furthermore, the first rotating block has a first connecting portion, and the upper clamping bar is provided with a first rotating groove, the first connecting portion being rotatably disposed within the first rotating groove.

The first clamping groove and the second clamping groove are used to clamp the wire together.

[0012] Due to the application of the above technical solution, this utility model has the following advantages compared with the prior art: This invention relates to a simple clamping wire feeder for a round wire heading machine. Because the upper and lower clamping bars can move away from or towards each other when rotating, and when they are close together, the bottom surface of the upper clamping bar and the top surface of the lower clamping bar are used to clamp the wire, the wire is clamped by two surfaces. In this way, the area of ​​the wire is increased when it is clamped, and no clamping marks are left on the surface of the wire. At the same time, there is no need for a solenoid valve, and the cost is low. Therefore, it solves the problem of wire clamping marks. Attached Figure Description

[0017] Furthermore, the technical features involved in the different embodiments of this utility model described below can be combined with each other as long as they do not conflict with each other.

[0018] like Figure 1 and Figure 2 and Figure 3 As shown, a simple clamp-type wire feeder for a round wire heading machine includes a base 1 and a wire clamping assembly 2. The wire clamping assembly 2 is disposed on the base 1, and the base 1 is fixed on the path of the moving wire 3.

[0019] The wire clamping assembly 2 includes a positioning block 21, a spring 22, an upper clamping bar 23, a lower clamping bar 24, a first limiting block 25, and a second limiting block 26. The positioning block 21 is mounted on the base 1 and is fixed to the base 1 by bolts. The positioning block 21 is provided with a sliding groove 27. The upper clamping bar 23 and the lower clamping bar 24 are rotatably mounted in the sliding groove 27. The upper clamping bar 23 is positioned above the lower clamping bar 24. The first limiting block 25 and the second limiting block 26 are respectively located at both ends of the sliding groove 27.

[0020] The first limiting block 25 is located in the moving direction of the upper clamping bar 23 and the lower clamping bar 24. The first end of the spring 22 abuts against the ends of the upper clamping bar 23 and the lower clamping bar 24, and the second end of the spring 22 abuts against the second limiting block 26. The upper clamping bar 23 and the lower clamping bar 24 are located between the first limiting block 25 and the second limiting block 26.

[0021] The spring 22 has a through hole 20. The first limiting block 25 is provided with a feed hole 28, and the second limiting block 26 is provided with a discharge hole 29. The feed hole 28, the through hole 20 and the discharge hole 29 are connected. The wire 3 passes through the feed hole 28, the through hole 20 and the discharge hole 29 in sequence. The bottom surface of the upper clamping bar 23 and the top surface of the lower clamping bar 24 are used to clamp the wire 3. In this way, the wire 3 is clamped by two surfaces, the clamping area is increased and the wire 3 will not have clamp marks.

[0022] The upper clamping bar 23 and the lower clamping bar 24 are configured such that the wire 3 is clamped by the bottom surface of the upper clamping bar 23 and the top surface of the lower clamping bar 24. When the upper clamping bar 23 and the lower clamping bar 24 rotate, they can move away from each other or move closer to each other. When the front end of the wire 3 is pulled, the wire 3 rubs against the upper clamping bar 23 and the lower clamping bar 24, and the upper clamping bar 23 and the lower clamping bar 24 will rotate. Under the action of rotation, the upper clamping bar 23 and the lower clamping bar 24 will separate from each other and loosen the wire 3. The spring 22 is compressed. The distance between the upper clamping bar 23 and the lower clamping bar 24 is less than the radial outer diameter of the spring 22. When the wire 3 is pulled away to a set length, the wire 3 is no longer pulled, and then the spring 22 is released to its natural state. Under the elastic force of the spring 22, the upper clamping bar 23 and the lower clamping bar 24 rotate in opposite directions to clamp the wire 3.

[0023] The wire clamping assembly 2 also includes a first adjusting bolt 201 and a second adjusting bolt 202. The first limiting block 25 and the positioning block 21 are connected by the first adjusting bolt 201.

The second limiting block 26 and the positioning block 21 are connected by the second adjusting bolt 202. The second adjusting bolt 202 is threadedly connected to the second limiting block 26 and the positioning block 21.

[0024] First, rotate the first adjusting bolt 201 to determine the position of the first limiting block 25 on the first adjusting bolt 201. Then, the first adjusting bolt 201 is threadedly connected to the positioning block 21, which can adjust the distance between the first limiting block 25 and the second limiting block 26. Next, rotate the second adjusting bolt 202 to determine the position of the second limiting block 26 on the second adjusting bolt 202. Then, the second adjusting bolt 202 is threadedly connected to the positioning block 21, which can adjust the distance between the second limiting block 26 and the first limiting block 25.

[0025] A recessed platform 250 is provided inside the discharge hole 29. A spring 22 extends into the discharge hole 29, and the second end of the spring 22 abuts against the recessed platform 250. The spring 22 can be compressed into the discharge hole 29. The second limiting block 26 can also prevent the upper clamping bar 23 and the lower clamping bar 24 from rotating.

[0026] The wire clamping assembly 2 also includes a first rotating block 203, a second rotating block 204, and a third rotating block 205. The first rotating block 203, the second rotating block 204, and the third rotating block 205 are rotatably disposed in the slide groove 27. The first rotating block 203 is located above the second rotating block 204 and the third rotating block 205. The upper clamping strip 23 is rotatably disposed on the first rotating block 203. The second rotating block 204 and the third rotating block 205 are spaced apart and disposed at the same height. The second rotating block 204 and the third rotating block 205 are rotatably connected to the lower clamping strip 24. In this way, the top surface of the lower clamping strip 24 always remains horizontal, and the bottom surface of the upper clamping strip 23 is flush with the top surface of the lower clamping strip 24.

[0027] The first rotating block 203, the second rotating block 204, and the third rotating block 205 are inclined. The connection between the first rotating block 203 and the upper clamping bar 23 is inclined in the direction of wire movement, and the connection between the second rotating block 204 and the third rotating block 205 and the lower clamping bar 24 is inclined in the direction of wire movement.

[0028] Furthermore, multiple positioning rods are provided inside the slide 27, and the first rotating block 203, the second rotating block 204 and the third rotating block 205 are respectively rotatably fixed on the corresponding positioning rods.

[0029] The first rotating block 203 has a first connecting part 207, and the upper clamping bar 23 is provided with a first rotating groove 231. The first connecting part 207 is rotatably disposed in the first rotating groove 231. The first connecting part 207 can only fall off from the axial opening of the first rotating groove 231. The first rotating groove 231 has a restrictive effect on the first connecting part 207, and the first connecting part 207 cannot fall off from the radial opening end of the first rotating groove 231.

The third connecting portion 209 cannot be dislodged from the axial opening of the third rotating groove 243, and can only be dislodged from the radial opening of the third rotating groove 243. The second rotating groove 241 has a restrictive effect on the second connecting portion 208, and the third rotating groove 243 has a restrictive effect on the third connecting portion 209.

[0031] The bottom end of the upper clamping bar 23 is provided with a first clamping groove 232, which passes through both ends of the upper clamping bar 23 axially. The upper end of the lower clamping bar 24 is provided with a second clamping groove 242, which passes through both ends of the lower clamping bar 24 axially.
