Description

Technical Field

[0001] This utility model relates to the technical field of welding wire transmission equipment, and in particular to a flux-cored welding wire transmission equipment. Background Technology

[0002] Flux-cored wire transfer typically involves placing the wire spool inside a cabinet, with two conduits inside the cabinet to ensure the direction of wire movement.

[0003] However, as the amount of welding wire wound on the wire spool decreases, the highest point of the welding wire on the spool gradually decreases. Since the height of the two guide tubes remains constant, the welding wire between the spool and the guide tube near the spool is tilted. As the feeding time progresses, the tilt of the welding wire in this section increases. This easily leads to wear on the surface of the welding wire fed in subsequent periods, affecting the quality of the finished welding wire. Utility Model Content

[0004] In view of the shortcomings of the existing technology, the purpose of this utility model is to provide a flux-cored welding wire transmission device, which can keep the welding wire in section B in a horizontal state at all times, avoid the welding wire being scratched and damaged by the inner wall of the passage port, and ensure the quality of the finished welding wire.

Detailed Implementation

[0015] The present invention will be further described in detail below with reference to the accompanying drawings. Example

[0016] Reference Figures 1-2 As shown, the present invention discloses a flux-cored welding wire transfer device, including a device body 1. The device body 1 includes a cabinet 11. The cabinet 11 has an opening on one side, and a movable door is provided at the opening.

[0017] The cabinet 11 is equipped with a solder pad placement assembly, and the solder wire spool is placed inside the solder pad placement assembly.

[0018] The cabinet 11 also includes a drive unit. The drive unit includes a first telescopic rod 41, which is fixed to the bottom of the inner wall of the cabinet 11. A first sliding plate 4 is fixed to the telescopic end of the first telescopic rod 41. The first sliding plate 4 is horizontally arranged inside the cabinet 11.

[0019] To limit the movement direction of the first sliding plate 4 and ensure that the first sliding plate 4 is always in a horizontal state, two second guide rods 6 are symmetrically fixed at the bottom of the inner wall of the cabinet 11. Both second guide rods 6 pass through the first sliding plate 4 and are slidably connected to the first sliding plate 4.

[0020] The pad placement assembly includes a first placement plate 3 and a locking plate 31. The first placement plate 3 is fixedly mounted on the top of the first sliding plate 4. A first fixing rod 32 is fixedly mounted on one side of the first placement plate 3, and a rotating tube 33 is rotatably sleeved on the outer circumference of the first fixing rod 32. The welding wire spool is located between the first placement plate 3 and the locking plate 31, and the welding wire spool is sleeved on the rotating tube 33. A nut is provided on the first fixing rod 32, which limits the position of the locking plate 31.

[0021] The wire spool rotates freely within the pad placement assembly, but the position of the pad remains unchanged.

[0022] In addition, the area of ​​the first placement plate 3 is large enough to ensure that the welding wire spool will not come into contact with the first placement plate 3 when it is placed on the first placement plate 3.

[0023] A first conduit 12 is fixedly installed on the upper half of one side of the cabinet 11, and a second conduit 13 is fixedly installed on the upper half of the inside of the cabinet 11. The welding wire passes through the second conduit 13 and the first conduit 12. The section between the first conduit 12 and the second conduit 13 is section A, and the section between the second conduit 13 and the welding wire spool is section B.

[0024] The welding wire in section A remains horizontal at all times. The welding wire in section B is initially horizontal, but as the amount of wire in the spool decreases, the wire in section B tilts. To ensure that the welding wire in section B remains horizontal at all times, a measuring unit is also installed inside cabinet 11.

[0025] The measuring unit includes a first rangefinder 2 and a second rangefinder 21. Both the first rangefinder 2 and the second rangefinder 21 are fixedly installed on the top of the cabinet 11. The first rangefinder 2 is located directly above section A, and the second rangefinder 21 is located directly above section B.

[0026] The distance from the first rangefinder 2 to the welding wire in section A is denoted as L1. The distance from the second rangefinder 21 to the welding wire in section B is denoted as L2. The drive unit moves the pad placement assembly so that L1 equals L2.

[0027] A controller (not shown in the figure) is also installed on the outside of the cabinet 11. The controller is electrically connected to the first rangefinder 2, the second rangefinder 21, and the first telescopic rod 41. The first rangefinder 2 and the second rangefinder 21 send the measured data to the controller. The controller uses L2 as a reference and adjusts the value of L2 by activating the first telescopic rod 41 according to the actual situation, so that L2 equals L1.

[0028] To ensure the direction of movement of the first placement plate 3 during movement and to define its placement state, a guide plate 42 is vertically fixed inside the cabinet 11. A first groove 43 is formed on one side of the guide plate 42, and a sliding block 44 is fixedly fixed on one side of the first placement plate 3. The sliding block 44 is located within the corresponding first groove 43, and the first groove 43 and the sliding block 44 are slidably connected. A first guide rod 5 is vertically fixed within the first groove 43, passing through the sliding block 44, and is slidably connected to the sliding block 44.

[0029] The implementation principle of the above embodiments is as follows: The operator places the welding wire spool between the first placement plate 3 and the locking plate 31, and then passes one end of the welding wire through the first through pipe 12 and the second through pipe 13.

[0030] The operator first activates the first rangefinder 2 and the second rangefinder 21, and both rangefinders 2 and 21 send the measured data to the controller. The controller uses the data measured by the first rangefinder 2 as a reference.

[0031] The entire device was adjusted before the welding wire was officially fed.

[0032] When the values ​​of L1 and L2 are equal, no adjustment is needed, and the values ​​of L1 and L2 can be seen on the display connected to the controller.

[0033] When the values ​​of L1 and L2 are not equal, the controller activates the first telescopic rod 41. By comparing the size and value of L1 and L2, the controller determines the extension or reduction of the first telescopic rod 41.

[0034] When L1 and L2 are adjusted to be equal, the controller stops the first telescopic rod 41 from working.

[0035] Next, the welding wire feeding operation will be started.

[0036] During the conveying operation, the first rangefinder 2 and the second rangefinder 21 can be selected to measure continuously or intermittently, depending on the actual situation. Based on the measurement results, the position and height of the first placement plate 3 are adjusted to ensure that the welding wire in section B is horizontal and that the welding wire in section B is on the same horizontal plane as the welding wire in section A.

[0037] The embodiments described herein are preferred embodiments of this utility model and are not intended to limit the scope of protection of this utility model. Therefore, all equivalent changes made to the structure, shape, and principle of this utility model should be included within the scope of protection of this utility model.
