Description

TECHNICAL FIELD

[0001] The utility model relates to welding wire processing technical field especially a kind of high wear-resistant flux-cored wire conveying mechanism. BACKGROUND

[0002] In the production and application field of high wear-resistant flux-cored wire, the performance of flux-cored wire conveying mechanism is crucial. It directly affects the quality and precision of flux-cored wire in subsequent processing links.

[0003] Through retrieval, the Chinese patent with publication number CN214827874U discloses a flux-cored wire conveying device, which includes a fixed box and a box cover hinged to the front side wall of the fixed box. This patent has good fixing effect on high wear-resistant flux-cored wire, making it more straight when being pulled out, and the operation is extremely convenient and simple, which is worth popularizing and using. By setting a disassembly and assembly component, rotating the rotating member and the lock cover, the lock cover drives the bolt to rotate and move out of the threaded hole. After removing the lock cover, the welding wire disc can be removed and replaced. Conversely, after screwing the bolt into the threaded hole, the welding wire disc can be fixed on the central shaft, making it convenient to replace the welding wire disc.

Especially for high wear-resistant flux-cored wire, its internal structure is complex and stress concentration is easily generated during production. The traditional roller extrusion correction cannot effectively eliminate this stress concentration, leading to the rebound phenomenon of flux-cored wire after correction, which makes it difficult to ensure the straightness precision of flux-cored wire and seriously affects the quality and effect of subsequent welding and other processing technologies.

Specific implementation

[0030] The utility model will be described in detail below, and the technical scheme of the embodiment of the utility model is clearly and completely described. Obviously, the described embodiment is only a part of the embodiment of the utility model, not all the embodiments. Based on the embodiment of the utility model, all other embodiments obtained by the ordinary skilled in the art without creative labor belong to the scope of protection of the utility model.

[0031] The utility model improves a kind of high wear-resistant flux-cored wire transmission mechanism, and the technical scheme of the utility model is:

[0032] Figures 1-5 It is the best embodiment of the utility model, the following is combined with the attached Figures 1-5 The utility model is further described.

[0033] As Figure 1 - Figure 5As shown, a kind of high wear-resistant flux-cored wire transmission mechanism, including processing box 1 and the limiting recess 102 of the hinge movable connection of processing box 1 front side, still include reel mechanism, traction mechanism and correction offset device.Reel mechanism is set in the inside of processing box 1, and the reel mechanism is wound with flux-cored wire body 7, and the other end of flux-cored wire body 7 extends outward from the side of processing box 1;Traction mechanism is set with multiple groups in the inside of processing box 1, and the traction mechanism is wound with the flux-cored wire body 7 on reel mechanism and is drawn outward;Correction offset device is set in the inside of processing box 1 away from reel mechanism side, and correction offset device is communicated with the inside and outside of processing box 1, and flux-cored wire body 7 passes through correction offset device and is discharged outward from the outside of processing box 1.The correction offset device includes correction box 6 and the wire inlet pipe 601 and bearing sleeve 602 of correction box 6 two sides, and the adjacent side between correction box 6 and bearing sleeve 602 is equipped with rotatable wire outlet pipe 603, and the other end of wire outlet pipe 603 is connected with the driving gear tube 8 in the inside of correction box 6, and the inside of driving gear tube 8 is transversely provided with the adjusting cavity 801 of the gradually decreasing inside diameter from wire inlet pipe 601 towards wire outlet pipe 603 direction, and the inside wall surface of adjusting cavity 801 is equipped with the matched helical limiting spiral tube 802, and correction box 6 is provided with the driving component of driving driving gear tube 8 rotation.

[0034] As Figure 3As shown, in an embodiment, the outer side of the driving gear tube 8 is provided with a threaded groove, the driving component includes a driven gear tube 901 which is engaged with the threaded groove of the outer side of the driving gear tube 8, the outer side of the correcting box body 6 is provided with a motor 9, the output shaft of the motor 9 extends into the inside of the correcting box body 6 and is fixed at the center of the connecting end of the driven gear tube 901. Through the setting of the motor 9, the driven gear tube 901 and the driving gear tube 8, the output shaft of the motor 9 drives the driven gear tube 901 to rotate, the driven gear tube 901 and the outer side of the driving gear tube 8 are engaged and connected to rotate synchronously, the rotating driving gear tube 8 can continuously offset and rotate the flux-cored wire body 7 in the driving gear tube 8 from the inlet to the outlet, and can multi-angle extrude and straighten the flux-cored wire body 7 entering the driving gear tube 8 from the inlet tube 601. Compared with the traditional two-roller extrusion correction, the spiral limiting spiral tube 802 is used to correct the flux-cored wire body 7, because the limiting spiral tube 802 is spiral and the diameter of the adjusting cavity 801 gradually decreases, the flux-cored wire body 7 will be subjected to extrusion force from different angles and gradually increasing when passing through, which can more comprehensively and effectively eliminate the bending and offset of the flux-cored wire body 7, and achieve better straightness correction effect. The straightened flux-cored wire body 7 passes through the bearing sleeve 602 and is pulled out of the outlet tube 603, the driving component drives the driving gear tube 8 to drive the internal spiral limiting spiral tube 802 to rotate and extrude the flux-cored wire body 7 passing through the inside of the driving gear tube 8, thereby improving the correction quality and precision of the flux-cored wire body 7.

[0035] As shown in the drawings, Figure 2 and Figure 4 As shown, in an embodiment, the front side of the processing box body 1 is provided with a limiting groove 102 which penetrates the outer side of the correcting box body 6, the outer shell of the correcting box body 6 is clamped in the inside of the corresponding limiting groove 102, the upper and lower ends of the correcting box body 6 are provided with reinforcing assemblies, the reinforcing assemblies include positioning blocks 604 which are connected at the outer shell of the correcting box body 6, and fixed pins 605 which are threadedly connected on the positioning blocks 604, and the correcting box body 6 inserted into the limiting groove 102 is threadedly fixed between the outer wall surface of the processing box body 1 through the fixed pins 605. Through the setting of the limiting groove 102, the positioning blocks 604 and the fixed pins 605, the detachable connection between the correcting offset device and the processing box body 1 is realized. On the one hand, when the correcting offset device fails or needs to be maintained, it can be conveniently extracted from the inside of the processing box body 1 for repair or replacement of parts; on the other hand, during installation, the correcting offset device can be quickly and accurately positioned and fixed on the processing box body 1, thereby ensuring the stability and reliability of the correcting offset device during the working process, so that it can continuously and effectively correct the flux-cored wire body 7.

By providing an L-shaped support frame plate 2 on the outside of the processing box 1, the outside of the processing box 1 is protected, reducing the influence of external factors on the internal components of the processing box 1. At the same time, the fixed bolt one 201 threadedly connected to the support frame plate 2 is downward (perpendicular) and backward (horizontal) reverse threaded connection (such as left-handed thread), which is opposite to the conventional thread rotation. When the equipment vibrates, the conventional right-handed thread may be loosened due to inertia, while the reverse thread will have a self-locking trend due to vibration, greatly reducing the risk of bolt loosening and ensuring the long-term stability of the protective plate. The vertical and horizontal direction of the bolt reverse fastening can offset the vibration impact in different dimensions, avoid the displacement of the protective plate caused by single direction stress, and improve the stability and safety of the whole equipment. In addition, the multi-scene installation adaptability makes the equipment flexible to install according to different working environments and needs. When the processing table is fixed, the edge of the bottom of the support frame plate 2 extends downward and is locked by the fixed bolt one 201 on the surface of the processing table, enhancing the rigid connection between the processing box 1 and the workbench and preventing the box from sliding or overturning due to processing vibration; when fixed on the wall, the horizontally extended edge of the back of the support frame plate 2 is connected to the pre-installed bracket on the wall through the reverse threaded fixed bolt one 201, suspending the processing box 1 and saving floor space while avoiding ground pollution and erosion of the bottom of the box, improving the space utilization and service life of the equipment.

Through the setting of multiple groups of traction mechanism and motor one 501, multiple groups of traction mechanism can provide stable and uniform traction force, ensuring that the flux-cored wire body 7 remains stable during transmission and avoiding shaking or deviation. The two motors one 501 located on the upper and lower sides of the flux-cored wire body 7 in each group of traction mechanism can pull the flux-cored wire body 7 from the upper and lower directions, increasing the stability and reliability of traction, preventing the flux-cored wire body 7 from twisting or bending during transmission, and ensuring that the flux-cored wire body 7 can be smoothly transmitted from the reel mechanism to the deviation correction device for correction.

The operation is simple and convenient, and the working efficiency is improved. At the same time, the nut member 401 limits the winding wheel 4 on the rod of the connecting roller shaft 301, which can effectively prevent the winding wheel 4 from falling off during work, and ensures the stability of the winding and transmission of the flux-cored wire body 7.

When the winding wheel 4 is installed on the connecting roller shaft 301, the clamping blocks 403 on one side of the winding wheel 4 are inserted into the clamping grooves 302 formed on the connecting roller shaft 301 to realize butt joint, so that the winding wheel 4 cannot rotate or shift on the connecting roller shaft 301, and the stability of the flux-cored wire body 7 during winding and transmission is ensured.
