Description

Technical Field

[0001] The utility model relates to the field of steel wire processing equipment, in particular to a fusing mechanism. Background Art

[0002] Twisted steel wire is a spiral steel wire bundle made by twisting together steel wires that meet the requirements of mechanical properties and geometric dimensions according to certain rules. The diameter of the twisted steel wire is very small, and it is usually made up of two or more strands of steel wire twisted together. In the absence of external force clamping, after the end of the steel wire is released, the steel wire will be released in the opposite direction of the twisting, and the part of the steel wire after release is unqualified and needs to be discarded.

[0003] In the process of testing the steel wire, it is inevitable to release the steel wire to test its torsion value. After the test is completed, in order to prevent the steel wire from loosening, it is generally bent or cut. Bending can ensure the integrity of the steel wire, but the ends will inevitably loosen; and cutting can only remove the loose parts, and after cutting, a new end will be exposed. If you do not consider preventing the ends from loosening again, then cutting will not solve the fundamental problem. Utility Model Content

[0004] To this end, the technical problem to be solved by the utility model is to overcome the problem in the prior art that after the twisted steel wire is cut, the end of the steel wire will become loose, and a fusing mechanism is provided, which can melt the end of the steel wire into one while clamping the steel wire, so as to prevent the steel wire from becoming loose again.

[0005] In order to solve the above technical problems, the utility model provides a fusing mechanism for fusing a steel wire, comprising:

[0006] A clamping assembly, comprising a fixed portion and a movable portion, wherein a clamping space is formed between the fixed portion and the movable portion;

[0007] A fuse assembly, comprising two fixed fuse blocks arranged at the fixed portion, two movable fuse blocks arranged at the end of the movable portion, and a capacitor, a gap is arranged between the two fixed fuse blocks, the two fixed fuse blocks are respectively connected to the positive and negative electrodes of the capacitor, and the two movable fuse blocks are arranged corresponding to the two fixed fuse blocks;

[0008] Wherein: the movable part drives the two movable fuse blocks to move toward the two fixed fuse blocks of the fixed part, so that the two movable fuse blocks and the two fixed fuse blocks are clamped on both sides of the steel wire, the steel wire and the capacitor form a conductive loop, and the short-circuit current passes through the steel wire to heat it, causing the steel wire to melt.

[0009] In one embodiment of the utility model, an insulating sheet is further included, wherein the insulating sheet includes two insulating arms, a groove is provided between the two insulating arms, and the two insulating arms are respectively arranged in the gap between the two fixed fuse blocks and the gap between the two movable fuse blocks.

[0010] In one embodiment of the utility model, it also includes: a guide plate, wherein the guide plate connects the two fixed fuse blocks and the positive and negative electrodes of the capacitor.

[0011] In one embodiment of the utility model, the movable part includes a pneumatic slide, and two movable fuse blocks are arranged on the pneumatic slide.

[0012] In one embodiment of the utility model, it further comprises: a bracket, wherein the bracket is arranged on one side of the clamping assembly, and a limited position channel is arranged on the bracket.

[0013] In an embodiment of the present invention, the bracket is provided with an opening communicating with the limiting channel.

[0014] In one embodiment of the utility model, a photoelectric detection sensor is further included, and the photoelectric detection sensor is used to detect whether the steel wire passes through the clamping space.

[0020] Furthermore, the fuse mechanism of the utility model uses the steel wire as the medium for conducting the current loop. Only when it is clamped can a short-circuit current be formed to cut the steel wire. On the one hand, it does not require continuous heat release to avoid energy waste.

DETAILED DESCRIPTION

[0028] The present invention will be further described below in conjunction with the accompanying drawings and specific embodiments so that those skilled in the art can better understand the present invention and implement it, but the embodiments are not intended to limit the present invention.

[0029] Reference Figure 1 As shown, the utility model discloses a fuse mechanism for fusing a steel wire, comprising: a clamping assembly and a fusing assembly, wherein: the clamping assembly comprises a fixed portion 1 and a movable portion 2, a clamping space is formed between the fixed portion 1 and the movable portion 2, the movable portion 2 can move toward or away from the fixed portion 1, and the steel wire to be fused is placed in the clamping space;

[0030] In this embodiment, the movable part 2 includes a pneumatic slide, which can push the movable part 2 to move. In other embodiments, other moving mechanisms can also be provided as long as it can ensure that the movable part 2 can move relative to the fixed part 1.

[0031] Reference Figure 2As shown, the fuse assembly includes two fixed fuse blocks 3 arranged on the fixed part 1, two movable fuse blocks 4 arranged at the ends of the movable part 2 and a capacitor 5, a gap is arranged between the two fixed fuse blocks 3, the two fixed fuse blocks 3 are connected to the positive and negative electrodes of the capacitor 5 respectively, and the two movable fuse blocks 4 are arranged corresponding to the two fixed fuse blocks 3. Similarly, a gap is also arranged between the two movable fuse blocks 4. When the steel wire is subjected to the fusing treatment, the movable part 2 is first arranged to drive the two movable fuse blocks 4 to move in a direction away from the two fixed fuse blocks 3 of the fixed part 1, so that the fixed part 1 and the movable part 2 are connected to each other. A clamping space is formed between the movable parts 2, so that the steel wire passes through the clamping space, and then the movable part 2 drives the two movable fuse blocks 4 to move toward the two fixed fuse blocks 3 close to the fixed part 1, so that the two movable fuse blocks 4 and the two fixed fuse blocks 3 are clamped on both sides of the steel wire, and the steel wire and the capacitor 5 form a conductive loop, and the short-circuit current heats the steel wire to melt the steel wire. The high temperature is generated by the short-circuit current to melt the steel wire. Compared with the stress shearing method, the ends of the fused steel wire can be fused into one, so that the steel wire can be prevented from becoming loose again.

[0032] Specifically, in the present embodiment, a gap is provided between the two fixed fuse blocks 3 so that the two fixed fuse blocks 3 cannot contact each other. In this way, when the steel wire is not clamped, it can be ensured that the two fixed fuse blocks 3 and the capacitor 5 are in a disconnected state, and no current flows through the two fixed fuse blocks 3. Only when the steel wire is placed in the clamping space and clamped by the two movable fuse blocks 4 and the two fixed fuse blocks 3, the steel wire is used as a medium for conducting the current loop and a short-circuit current is formed to clamp the steel wire. On the one hand, there is no need for continuous heat release to avoid energy waste. On the other hand, a short circuit can be formed immediately after the steel wire is clamped, which can also play a certain protective role for the entire mechanism.

[0033] In actual use, in order to prevent the two fixed fuse blocks 3 from being misconnected, for example, the cut steel wire splashes between the two fixed fuse blocks 3; therefore, the two fixed fuse blocks 3 need to be blocked, refer to Figure 2 As shown, in this embodiment, the fuse assembly also includes an insulating sheet 6, which includes two insulating arms, and a groove is provided between the two insulating arms, wherein the groove corresponds to the position of the clamping space, and the steel wire can pass through the groove. The two insulating arms are respectively arranged in the gap between the two fixed fuse blocks 3 and the gap between the two movable fuse blocks 4, so as to insulate and block the two parts of the fuse assembly.

[0034] Specifically, one of the insulating arms of the insulating sheet 6 is fixed on the fixed fuse block 3 , the insulating sheet 6 is protruded toward the movable fuse block 4 , and the other insulating arm of the insulating sheet 6 is embedded in the gap between the two movable fuse blocks 4 .

[0035] Specifically, refer to Figure 2 As shown, in this embodiment, in order to realize the connection between the two fixed fuse blocks 3 and the positive and negative electrodes of the capacitor 5, the fuse assembly also includes a guide plate, which connects the two fixed fuse blocks 3 and the positive and negative electrodes of the capacitor 5. The width of the guide plate is much larger than the diameter of the steel wire, and the current-carrying capacity of the guide plate is much larger than that of the steel wire. In this way, when a large current passes through the steel wire, it can heat up and melt, and prevent the guide plate from heating up and melting.

[0036] During actual use, the clamping assembly of this embodiment can only be activated when there is a steel wire in the clamping space of the clamping assembly. Therefore, in order to detect whether the steel wire passes through the clamping space, the fuse assembly also includes a photoelectric detection sensor capable of detecting the steel wire. The photoelectric detection sensor is equivalent to the safety switch of the clamping assembly. The clamping assembly is allowed to be opened only when the photoelectric detection sensor detects that the steel wire passes through the clamping space of the clamping assembly.

[0037] In this embodiment, when there is no need to clamp the steel wire, the movable part 2 moves in the direction as far away from the fixed part 1 as possible, forming a clamping space between the movable part 2 and the fixed part 1, and the steel wire passes through the clamping space. However, since the travel of the movable part 2 is limited, the clamping space formed between the movable part 2 and the fixed part 1 is limited. When the steel wire passes through the clamping space, due to the problem of wire release tension, the wire release may be unstable, and the steel wire may occasionally shake when it is released. When shaking, the released steel wire is easy to contact with the fixed fuse block 3, causing misfire, and there is a risk of the steel wire being melted. In order to avoid this risk, the steel wire must be limited before it passes through the clamping space. Therefore, referring to Figure 3 In the fuse mechanism of the present embodiment, a bracket 7 is further provided. The bracket 7 is provided on one side of the clamping assembly. A limiting channel 71 is provided on the bracket 7. During the process of unwinding the steel wire, the steel wire is first placed in the limiting channel 71. After the position of the steel wire is limited by the limiting channel 71, the steel wire is passed through the clamping space. In this way, the shaking of the steel wire can be limited, and the situation of no contact between the steel wire and the fixed fuse block 3 can be prevented.

[0038] Reference Figure 4As shown, the fusing mechanism also includes: a receiving table 8, which is arranged below the clamping assembly. The cut steel wire will fall into the receiving table 8. In this embodiment, due to limited space, the receiving table 8 is arranged as an inclined block. The cut steel wire can fall onto the receiving table 8 and slide along the inclined surface of the receiving table 8 into the waste bin.

[0039] Reference Figure 5 As shown, in order to prevent the steel wire from accidentally contacting the fixed fuse block 3 when the steel wire is normally paid out, a lifting component 9 can also be provided in the fuse mechanism of this embodiment. The lifting component 9 is arranged below the clamping component. When the steel wire is normally paid out, the lifting component 9 drives the clamping component to avoid, and the steel wire will not pass through the fuse mechanism, thereby completely avoiding the steel wire from being accidentally clamped off.

[0040] Specifically, the lifting assembly 9 includes: a lifting slide 91 and a limit block 92. The limit block 92 is arranged on the moving path of the lifting slide 91. The limit block 92 limits the initial position and the end position of the movement of the lifting slide 91. Through mechanical limiting, the moving position of the clamping assembly can be accurately limited to ensure that the steel wire can accurately pass through the clamping space of the clamping assembly.

[0041] Specifically, the lifting assembly 9 drives the clamping assembly to move as a whole. During the movement, in order to enable the steel wire to accurately move into the limiting channel 71 of the bracket 7, the bracket 7 is provided with an opening connected to the limiting channel 71. The opening can increase the length of the captured steel wire, and after the steel wire is captured, the steel wire can be introduced into the limiting channel 71 along the opening.

[0042] Obviously, the above embodiments are merely examples for the purpose of clear explanation and are not intended to limit the implementation methods. For those skilled in the art, other different forms of changes or modifications can be made based on the above description. It is not necessary and impossible to list all the implementation methods here. The obvious changes or modifications derived therefrom are still within the scope of protection of the invention of the utility model.
