Description

TECHNICAL FIELD

[0001] The application belongs to the technical field of wire detection, and particularly relates to a wire detection device with good heat dissipation effect. BACKGROUND

[0002] The existing wire needs to be detected by a wire detection device before being put into use. The wire detection device comprises a bending structure and a positioning structure. One end of the wire is fixed to the bending structure, and the other end is fixed to the positioning structure. The wire is driven to rotate through the rotation of the bending structure. The bending structure comprises a bending piece for clamping the wire. The lower end of the bending piece is used for abutting against the wire to realize the bending of the wire. However, in the repeated bending process of the wire, the bending piece repeatedly contacts the surface of the wire, which will cause the bending part of the wire to heat up. At the same time, stress is concentrated at the bending part of the wire, which will generate a concentrated heat source, causing the bending part of the wire to heat up and affecting the detection accuracy of the wire.

[0003] The existing steel detection device comprises a heat dissipation mechanism and a bending mechanism. The bending mechanism is arranged at one end of the top surface of the bottom plate, and the heat dissipation mechanism is arranged at the middle position of the top surface of the bottom plate. The structure of the bending mechanism will block the airflow of the heat dissipation mechanism, so that the airflow cannot reach the bending part of the steel, and the bending part of the steel cannot be cooled, causing the bending part of the steel to heat up and affecting the detection accuracy of the steel. CONTENT OF THE INVENTION

[0004] The application provides a wire detection device with good heat dissipation effect to solve the technical problem that the existing wire detection device cannot dissipate heat from the bending part of the wire, affecting the detection accuracy of the wire.

The support piece is provided with a positioning hole. The bending piece is detachably arranged in the positioning hole. The bending piece extends towards the positioning structure and at least partially exposes the positioning hole. The bending piece is used for clamping the wire. The bending structure further comprises a flow guide piece. The flow guide piece is arranged on the side of the mounting piece away from the rotating shaft. When the bending structure rotates, the flow guide piece guides the airflow to blow towards one end of the bending piece towards the positioning structure.

[0007] The wire detection device with good heat dissipation effect in the application further comprises the following additional technical features:

[0008] The flow guide extends to the support, and the flow guide is arranged protruding towards the bending piece.

[0009] The mounting piece is provided with a plurality of flow guides, which are arranged in an arc shape around the axis direction of the rotating shaft, and one end of the flow guide points to the axis of the rotating shaft.

[0010] The flow guide is provided with a flow guide hole facing the bending piece, the mounting piece is provided with an air inlet channel communicating with the flow guide hole, and the wire detection device further comprises a gas conveying mechanism for conveying gas flow to the air inlet channel.

[0011] The wire detection device further comprises a driving mechanism and a connecting structure, the driving mechanism comprises an output shaft and a rotating disc connected to the output shaft, the connecting structure comprises a connecting rod, a connecting shaft and a driving gear, the driving gear is arranged on the connecting shaft, the connecting shaft can rotate relative to the positioning structure, one end of the connecting rod is rotatably connected to the eccentric position of the rotating disc, and the other end is rotatably connected to the driving gear, the bending structure further comprises a driven gear arranged on the rotating shaft, the driven gear can be engaged with the driving gear, and the gas conveying mechanism is arranged between the driven gear and the base.

[0012] The gas conveying mechanism comprises a pawl arranged on the rotating shaft and a ratchet wheel rotatably arranged on the rotating shaft, and the ratchet wheel is connected to the impeller.

[0013] The gas flow generated by the rotation of the impeller forms a coverage area in the mounting piece, and the air inlet channel is arranged in the coverage area.

[0014] The flow guide is provided with a flow guide hole, and a plurality of flow guide holes are arranged along the axis direction of the flow guide.

[0015] The mounting piece is provided with an air inlet channel communicating with the flow guide hole, the wire detection device further comprises a gas conveying mechanism for conveying gas flow to the air inlet channel, the air inlet channel is arranged tapering along the direction of the gas flow, and the cross-sectional area of the air inlet end of the air inlet channel is greater than that of the air outlet end of the air inlet channel.

[0016] The flow guide hole extends towards the mounting piece, a spiral flow guide groove is formed in the hole wall of the flow guide hole along the direction of the gas flow, the edge of the mounting piece is connected to a flow guide cover, and the flow guide cover extends towards the gas conveying mechanism.

[0017] As the above technical scheme is adopted, the beneficial effects of the present application are as follows:

[0018] 1. This application features a detachable bending component mounted in the positioning hole. Users can adjust the bending component model according to the wire specifications, improving the applicability of the wire testing device. By ensuring the bending component is at least partially exposed in the positioning hole, on one hand, the end of the bending component facing the positioning structure is used for bending the wire. By extending the bending component towards the positioning structure and at least partially exposing it in the positioning hole, the part of the bending component that bends the wire is removed from the positioning hole, preventing heat generated during bending from accumulating in the positioning hole and improving heat dissipation at the bending point. On the other hand, by ensuring the bending component is at least partially exposed in the positioning hole, the airflow guided by the guide component can be directed towards the end of the bending component facing the positioning structure, improving the heat dissipation efficiency of the bending point and thus improving the wire testing accuracy. Simultaneously, by rotating the bending structure, the guide component guides the airflow, enabling the guide component to dissipate heat through the rotation of the bending structure, achieving directional heat dissipation at the bending point and quickly removing the heat generated during bending.

[0019] 2. In a preferred embodiment of this application, by providing a guide member extending to the support member and protruding towards the bending member, the protruding structure of the guide member can focus and guide airflow to the bending member, dissipating heat at the bending point of the wire and preventing heat generated by repeated bending friction from accumulating between the mounting member, the bending member, and the support member. Furthermore, the support member protruding towards the bending member brings the guide member and the bending member closer together, shortening the airflow transmission distance and precisely guiding the airflow towards the bending point of the wire. Simultaneously, when the bending structure rotates, the guide member also rotates accordingly. Regardless of the bending member's angle, the guide member can always guide the airflow to the area where the bending member contacts the wire, achieving synchronization between airflow guidance and bending action. By extending the guide member to the support member and protruding towards the bending member, the area of ​​the guide member is increased, allowing the airflow guided by the guide member to cover more areas of the bending member and reducing airflow blind spots. Furthermore, the guide component can connect the support component and the bending component, thereby improving the overall strength of the bending structure.

[0020] 3. In a preferred embodiment of this application, multiple airflow guides are arranged in an arc shape around the axis of the rotating shaft, with one end of each guide pointing towards the axis of the rotating shaft. This precisely directs the airflow to the bending section of the wire, avoiding ineffective airflow towards non-bending sections and enhancing heat dissipation at the bending section. Furthermore, when the bending structure rotates, the multiple airflow guides arranged in an arc shape maintain a dynamic match between the airflow direction and the bending trajectory of the wire, improving the heat dissipation effect.

[0021] 4. As a preferred embodiment of this application, by setting an air supply mechanism, the air supply mechanism delivers airflow through the air inlet channel and the air guide hole, and the air guide hole delivers the airflow to the bending part. By actively delivering airflow, the airflow of the wire during the bending process is further improved, thereby improving the heat dissipation efficiency of the wire and the bending part.

[0022] Furthermore, by setting up a drive mechanism and a connecting structure, the reciprocating oscillation of the bending structure is realized, thereby achieving repeated bending of the wire. Under the premise that the output shaft rotates continuously in the same direction, the bending structure drives the wire to bend reciprocally. By placing the air supply mechanism between the driven gear and the base, the driven gear is prevented from obstructing the air supply mechanism from delivering airflow to the air intake channel.

[0023] 5. As a preferred embodiment of this application, by setting the pawl on the rotating shaft, the rotation of the shaft directly drives the impeller, converting the mechanical energy of the shaft into the kinetic energy of the airflow. This eliminates the need for an additional power source and simplifies the setup of the wire detection device. Through the one-way locking mechanism between the ratchet and the pawl, the impeller maintains continuous rotation in the same direction during the reciprocating oscillation of the shaft. For example, when the shaft rotates forward, the pawl pushes the ratchet, causing the impeller to rotate at high speed; when rotating in the reverse direction, the pawl slides past the ratchet, and the impeller's inertia maintains its original rotation direction, improving the continuity of airflow output and avoiding airflow interruption.

[0024] Furthermore, by placing the air intake channel within the coverage area, the air intake channel can receive more airflow, increasing the airflow intensity of the guide hole and further improving the heat dissipation efficiency of the wire bending section.

[0025] 6. As a preferred embodiment of this application, by setting multiple guide holes at intervals along the axial direction of the guide member, the coverage area of ​​the airflow is expanded, forming a continuous cooling band along the length of the wire, improving the heat dissipation coverage, and the airflow of adjacent guide holes interacts to form a superposition effect, thereby improving the local heat exchange efficiency of the wire.

[0026] Furthermore, by designing the air intake channel to gradually narrow along the airflow direction, the airflow is continuously accelerated within the intake channel. The high-speed airflow ejected from the guide holes can quickly remove heat from the bending area of ​​the wire, improving heat dissipation efficiency. The narrowing air intake channel helps to distribute the airflow more evenly within the channel. When the airflow enters the intake channel from the air delivery mechanism, the larger intake end allows sufficient space for buffering and adjustment. Then, during the narrowing process, the airflow is gradually regularized and can be more evenly distributed to each guide hole. This ensures that the airflow intensity and direction ejected from each guide hole are relatively consistent, thereby improving the overall heat dissipation uniformity of the wire.

[0027] Further, the spiral flow guide groove is arranged to make the air flow rotate, and the rotating air flow impacting the bending part of the wire can further improve the heat dissipation efficiency. The flow guide cover is arranged to gather the air flow delivered by the air delivery mechanism, improve the air flow into the air delivery channel, and avoid air flow loss.

[0049] In the present application, the bending piece 13 is detachably arranged in the positioning hole 1231, the user can adjust the model of the bending piece 13 according to the specifications of the wire, thereby improving the applicability of the wire detection device, the bending piece 13 at least partially exposes the positioning hole 1231, on the one hand, one end of the bending piece 13 away from the positioning structure 2 is used for bending the wire, and on the other hand, the bending piece 13 extends towards the positioning structure 2 and at least partially exposes the positioning hole 1231, thereby separating the part of the bending piece 13 bending the wire from the positioning hole 1231, avoiding the accumulation of heat generated in the wire bending process in the positioning hole 1231, improving the heat dissipation effect of the wire bending part, improving the heat dissipation efficiency of the wire bending part, and further improving the detection accuracy of the wire. At the same time, the bending structure 1 is arranged to rotate to drive the flow guide piece 14 to guide the airflow, so that the flow guide piece 14 can realize heat dissipation by rotating the bending structure 1, realize directional heat dissipation of the wire bending part, and quickly remove the heat generated in the wire bending part during the bending process.

[0050] In the present application, the flow guide piece 14 can be arranged in any of the following embodiments:

[0051] Embodiment one: as shown in FIGS. 1, 2 and 3, the flow guide piece 14 extends to the support piece 123, and the flow guide piece 14 is protrudingly arranged towards the bending piece 13. Figure 3 Figure 4 Embodiment two: as shown in FIGS. 4, 5 and 6, the flow guide piece 14 is arranged on the rotating shaft 11.

[0052] ​By setting the flow guide 14 to extend to the support 123, the flow guide 14 extends to the support 123 and is protrudingly arranged towards the bending piece 13. The protruding structure of the flow guide 14 can focus and guide the airflow to the bending piece 13, dissipate heat at the wire bending position, and avoid heat accumulation between the mounting piece 121, the bending piece 13, and the support 123 due to repeated bending friction. Moreover, the support 123 is protrudingly arranged towards the bending piece 13, the relative position of the flow guide 14 and the bending piece 13 is closer, the airflow transmission distance is shortened, and the airflow is accurately guided to flow towards the wire bending position. At the same time, when the bending structure 1 rotates, the flow guide 14 also rotates, and no matter what angle the bending piece 13 is at, the flow guide 14 can always guide the airflow to the position where the bending piece 13 contacts the wire, realizing the synchronization of airflow guiding and bending action. By setting the flow guide 14 to extend to the support 123, the flow guide 14 is protrudingly arranged towards the bending piece 13, the area of the flow guide 14 is increased, the airflow guided by the flow guide 14 can cover more areas of the bending piece 13, and the airflow blind area is reduced. Moreover, the flow guide 14 can play a role in connecting the support 123 and the bending piece 13, and improving the overall strength of the bending structure 1.

[0053] Embodiment two: The embodiment two is not shown, and is different from the embodiment one in that the flow guide extends towards the support, and the flow guide is arranged in space with the support.

[0054] In the embodiment one, the arrangement mode of the flow guide 14 can be any one of the following embodiments:

[0055] Embodiment 1: As shown in Figure 3 , Figure 8 The mounting piece 121 is provided with a plurality of flow guides 14, the plurality of flow guides 14 are arranged in an arc shape around the axis direction of the rotating shaft 11, and one end of the flow guide 14 points to the axis of the rotating shaft 11.

[0056] By setting the plurality of flow guides 14 to be arranged in an arc shape around the axis direction of the rotating shaft 11, and one end of the flow guide 14 to point to the axis of the rotating shaft 11, the airflow is accurately guided to the wire bending position, invalid air supply towards the non-bending position is avoided, and the heat dissipation of the wire bending position is strengthened. Moreover, when the bending structure 1 rotates, the plurality of flow guides 14 arranged in an arc shape can keep the dynamic matching of the airflow direction and the bending track of the wire during the rotating process, and improve the heat dissipation effect.

[0057] Embodiment 2: The embodiment 2 is not shown, and the mounting piece is provided with a plurality of flow guides, and the plurality of flow guides are arranged in a circumferential direction.

[0058] Embodiment 3: The embodiment 3 is not shown, and the mounting piece is provided with a plurality of flow guides, and the plurality of flow guides are arranged in space along the width direction of the mounting piece.

[0059] As a preferred embodiment 4 of the embodiment one:Figure 3 , Figure 4 , Figure 6 , Figure 7 As shown, the guide member 14 has a guide hole 141 facing the bending member 13, and the mounting member 121 has an air intake channel 1211 communicating with the guide hole 141. The wire detection device also includes an air delivery mechanism 5 for delivering airflow to the air intake channel 1211. Those skilled in the art will understand that the guide member 14 or the mounting member 121 can be integrated with the air delivery mechanism 5, and the airflow can be delivered by wireless control. In this application, the connection method between the guide member 14 and the mounting member 121 is not limited. The guide member 14 and the mounting member 121 can be connected by bolts, or the guide member 14 can be welded to the mounting member 121, or the guide member 14 and the mounting member 121 can be integrally formed, or the guide member 14, the mounting member 121 and the support member 123 can be integrally formed.

[0060] By setting up an air supply mechanism 5, the air supply mechanism 5 delivers airflow through the air inlet channel 1211 and the airflow guide hole 141. The airflow guide hole 141 delivers the airflow to the bending part 13. Combined with the airflow guide 14 protruding towards the bending part 13, the airflow is precisely guided. By actively delivering airflow, the airflow of the wire during the bending process is further improved, the heat dissipation efficiency of the wire is improved, and the heat dissipation efficiency of the bending part 13 is also improved.

[0061] In embodiment 4, the rotation configuration of the rotating shaft 11 can be any of the following specific examples:

[0062] Specific example 1: if Figure 1 , Figure 2 , Figure 3 As shown, the wire testing device also includes a drive mechanism 3 and a connecting structure 4. The drive mechanism 3 includes an output shaft 31 and a turntable 32 connected to the output shaft 31. The connecting structure 4 includes a connecting rod 41, a connecting shaft 42, and a drive gear 43. The drive gear 43 is disposed on the connecting shaft 42, which can rotate relative to the positioning structure 2. One end of the connecting rod 41 is rotatably connected to the eccentric position of the turntable 32, and the other end is rotatably connected to the drive gear 43. The bending structure 1 also includes a driven gear 15 disposed on the rotating shaft 11, which can mesh with the drive gear 43. The air supply mechanism 5 is disposed between the driven gear 15 and the base 12.

[0063] By setting the drive mechanism 3 and the connecting structure 4, the bending structure 1 is reciprocated, thereby achieving repeated bending of the wire. Under the premise that the output shaft 31 rotates continuously in the same direction, the bending structure 1 drives the wire to bend repeatedly. By setting the air supply mechanism 5 between the driven gear 15 and the base 12, the driven gear 15 is prevented from blocking the air supply mechanism 5 from supplying air to the air intake channel 1211.

[0064] Specific Example 2: This specific example 2 is not illustrated. The wire bending detection device also includes a drive mechanism. The drive mechanism includes an output shaft, which is connected to a rotating shaft. The drive mechanism can adjust the reciprocating rotation of the output shaft. The air supply mechanism is located close to the mounting component.

[0065] In specific examples 1 and 2, the air supply mechanism 5 can be configured in any of the following examples:

[0066] Example 1: such as Figure 3 As shown, the air delivery mechanism 5 includes a pawl 51 fixedly mounted on the rotating shaft 11 and a ratchet 52 rotatably mounted on the rotating shaft 11, with the ratchet 52 connected to the impeller 53. By mounting the pawl 51 on the rotating shaft 11, the rotation of the rotating shaft 11 directly drives the impeller 53, converting the mechanical energy of the rotating shaft 11 into the kinetic energy of the airflow, eliminating the need for an additional power source and simplifying the setup of the wire detection device. Through the one-way locking mechanism between the ratchet 52 and the pawl 51, when the rotating shaft 11 reciprocates, the impeller 53 always maintains continuous rotation in the same direction. For example, when the rotating shaft 11 rotates forward, the pawl 51 pushes the ratchet 52 to drive the impeller 53 to rotate at high speed; when rotating in the reverse direction, the pawl 51 slides past the ratchet 52, and the impeller 53 maintains its original rotation direction due to inertia, improving the continuity of airflow output and avoiding airflow interruption problems.

[0067] Furthermore, the airflow generated by the rotation of the impeller 53 forms a coverage area on the mounting component 121, and the air intake channel 1211 is disposed in the coverage area. By disposing the air intake channel 1211 in the coverage area, the air intake channel 1211 can receive more airflow, increasing the airflow intensity of the guide hole 141 and further improving the heat dissipation efficiency of the wire bending section.

[0068] Example 2: This example 2 is not illustrated. The air supply mechanism includes a magnet fixedly mounted on a rotating shaft and an impeller rotatably mounted on the rotating shaft. The impeller is provided with connecting magnets that match the magnet at intervals. When the rotating shaft rotates, the impeller is driven to rotate continuously by the magnetic field.

[0069] As a preferred embodiment of this application, the third method is as follows: Figure 6 As shown, the flow guide 14 is provided with flow guide holes 141, and multiple flow guide holes 141 are spaced apart along the axial direction of the flow guide 14.

[0070] By setting multiple guide holes 141 at intervals along the axial direction of the guide member 14, the coverage area of ​​the airflow is expanded, forming a continuous cooling band along the length of the wire, improving the heat dissipation coverage. The airflow of adjacent guide holes 141 interacts to form a superposition effect, improving the local heat exchange efficiency of the wire.

[0071] As a preferred embodiment 5 in implementation method three: Figure 3 , Figure 6 , Figure 7As shown, the mounting member 121 is provided with an air inlet channel 1211 which is in communication with the flow guide hole 141, and the wire detection device further comprises a gas feeding mechanism 5 for feeding gas flow to the air inlet channel 1211, the air inlet channel 1211 is tapered in the direction of the gas flow, and the cross-sectional area of the air inlet end of the air inlet channel 1211 is greater than that of the air outlet end of the air inlet channel 1211.

[0072] Further, the mounting member 121 is further provided with a guide groove 1212 on the side facing the gas feeding mechanism 5, and the air inlet channel 1211 is arranged in the guide groove 1212.

[0073] By tapering the air inlet channel 1211 in the direction of the gas flow, the gas flow is continuously accelerated in the air inlet channel 1211, and the high-speed gas flow sprayed from the flow guide hole 141 can quickly take away the heat of the wire bending part, thereby improving the heat dissipation efficiency. The tapered air inlet channel 1211 helps to make the gas flow more uniformly distributed in the channel. When the gas flow enters the air inlet channel 1211 from the gas feeding mechanism 5, the larger air inlet end can provide enough space for the gas flow to buffer and adjust, and then in the process of tapering, the gas flow is gradually regularized and can be more evenly distributed to each flow guide hole 141. In this way, the gas flow intensity and direction sprayed from each flow guide hole 141 can be relatively consistent, thereby improving the uniformity of heat dissipation of the wire as a whole.

[0074] Further, as shown in Figure 3 、 Figure 6 、 Figure 7 , the flow guide hole 141 extends towards the mounting member 121, and the hole wall of the flow guide hole 141 is provided with a spiral flow guide groove (not shown in the figure) in the direction of the gas flow, and the edge of the mounting member 121 is connected with a flow guide cover 122 which extends towards the gas feeding mechanism 5.

[0075] By setting the spiral flow guide groove, the gas flow can be rotated, and the rotating gas flow impacting the wire bending part will further improve the heat dissipation efficiency. By setting the flow guide cover 122, the gas flow fed by the gas feeding mechanism 5 is converged, the gas flow into the air inlet channel is increased, and the gas flow is prevented from being dissipated.

[0076] In Example 5, the air inlet channel 1211 can be arranged in any of the following examples:

[0077] Example 3: As shown in Figure 6 、 Figure 7 , the air inlet channel 1211 can be arranged in multiple, and one air inlet channel 1211 corresponds to one flow guide hole 141.
