An electromagnetic adjustment mechanism and a wire feeder including the electromagnetic adjustment mechanism

Abstract

The present invention provides an electromagnetic mediation mechanism and a wire feeder including the electromagnetic mediation mechanism. The wire feeder includes an electromagnetic mediation mechanism, a housing, a first wool wheel, a second wool wheel and a driving motor. The coil and the iron core of the electromagnetic mediation mechanism are electromagnet structures. The coil is wound into a solenoid. When current flows into the coil, the iron core is magnetized and has magnetism, attracting the iron block to move upward. The first connecting rod moves upward accordingly. The movable block rotates around the second connecting rod under the drive of the first connecting rod. The mediation block fixed on the second connecting rod rotates to lift the welding wire. The welding wire loses contact with the two wool wheels and stops moving forward. The electromagnetic mediation mechanism described in the present invention has a simple structure, high stability, simple mediation and easy operation. The wire feeder is small in size, easy to manufacture and low in cost. If wire jamming occurs during the wire feeding process, the machine can be stopped or semi-stopped to adjust the speed of the wool wheel or the wire feeding wheel, and partial or overall fault detection of the wire feeder can also be achieved.

[0031] The present invention will be described in detail below with reference to the accompanying drawings and in conjunction with embodiments.

[0032] like Figure 1-3 As shown, a wire feeder including an electromagnetic regulating mechanism includes an electromagnetic regulating mechanism 1, a box body 2, a protective cover 3, a wire release rack 4, a first wool wheel 5, a second wool wheel 6, a first wire feeding wheel 7, a second wire feeding wheel 8, a third wire feeding wheel 9, a fourth wire feeding wheel 10, a three-tube 12 and a driving motor.

[0033] like Figure 4-7 As shown, the electromagnetic adjustment mechanism of the wire feeder mainly includes a coil 101, an iron core 102, an iron block 105, a first connecting rod 106, a second connecting rod 109, a movable block 107, an adjustment block 110, a first fixed block 108, a second fixed block 111, a bolt 112, a adjustment button 115 and a reset button 116.

[0034] The coil 101 and the iron core 102 are electromagnet structures. The coil 101 is wound into a solenoid, and the iron core 102 is inserted into the solenoid. Current is passed into the coil 101 to magnetize the iron core 102. When the power is off, the magnetization of the magnetized iron core 102 disappears. The coil 101 is placed in the frame 103, and the frame 103 protects the coil 101. The iron block 105 is magnetically matched with the iron core 102, and the iron block 105 moves up and down in the vertical direction depending on whether the iron core 102 is magnetic. The lower end of the iron block 105 is connected to the first connecting rod 106 through a locking part 113, and the other end of the first connecting rod 106 is hinged to the movable block 107. The second connecting rod 109 is installed on the side of the other end of the movable block 107, so that the movable block 107 and the second connecting rod 109 form an "L"-shaped structure. The mediation block 110 is fixedly installed in the middle of the second connecting rod 109.

[0035] The first fixed block 108 has a through hole for matching with the second connecting rod 109. The first fixed block 108 is mounted on the second connecting rod 109 and can slide freely on the second connecting rod 109 between the movable block 107 and the mediation block 110. The second fixed block 111 has a hole for matching with the second connecting rod 109. The second connecting rod 109 is inserted into the hole of the second fixed block 111. The electromagnetic mediation mechanism 1 is located above the box 2. The first fixed block 108 and the second fixed block 111 are fixedly installed on the upper surface of the box 2. The second connecting rod 109 of the electromagnetic mediation mechanism 1 can rotate freely and cross the advancing direction of the welding wire 13. The bolt 112 passes through the upper and lower surfaces of the movable block 107. The mediation button 115 is used to control the coil 101 of the electromagnetic mediation mechanism 1 to connect the power supply; the reset button 116 is used to control the coil 101 of the electromagnetic mediation mechanism 1 to disconnect the power supply.

[0036] The first rough wheel 5 and the second rough wheel 6 are installed on the upper surface of the box body 2, and the connecting line of the centers of the two rough wheels is perpendicular to the advancing direction of the welding wire; the specifications of the two rough wheels are the same. The wire placing rack 4 is fixed on the upper surface of the box body 2 and is used to store the welding wire 13.

[0037] The first wire feeding wheel 7 and the second wire feeding wheel 8 are used in pairs, and similarly, the third wire feeding wheel 9 and the fourth wire feeding wheel 10 are used in pairs; the two wire feeding wheels in each pair of wire feeding wheels have the same specifications. The wire feeding wheels are installed on the upper surface of the box body 2, and the connecting line of the centers of each pair of wire feeding wheels is perpendicular to the advancing direction of the welding wire. A three-piece tube 12 is used as a welding wire guide device.

[0038] The protective cover 3 covers the outside of the electromagnetic mediation mechanism 1, the wire feeding frame 4, the first wool wheel 5 and the second wool wheel 6, and is used to protect the safety of the operator and isolate dust. The upper surface of the frame 103 of the electromagnetic mediation mechanism 1 is connected to the fixing frame 104, which is convenient for the disassembly and assembly of the electromagnetic mediation mechanism 1; the fixing frame 104 is installed on the top inner surface of the protective cover 3, and the frame 103 is fixedly connected to the protective cover 3 through the fixing nut 114.

[0039] The driving motor is installed inside the box body 2, and provides rotational driving force for the first wool wheel 5, the second wool wheel 6, the first wire feeding wheel 7, the second wire feeding wheel 8, the third wire feeding wheel 9 and the fourth wire feeding wheel 10 respectively.

[0040] The driving motor is installed inside the box to provide driving force for the rotation of the first wool wheel 5, the second wool wheel 6, the first wire feeding wheel 7, the second wire feeding wheel 8, the third wire feeding wheel 9 and the fourth wire feeding wheel 10.

[0041] Working principle: When the wire feeder operates normally, the welding wire 13 is lowered from the wire release rack 4 in an orderly manner, the bottom welding wire 13 contacts the first wool wheel 5 and the second wool wheel 6, and is fed into the first section of the three-tube 12. After coming out, the welding wire 13 is fed into the second section of the three-tube 12 by the first wire feeding wheel 7 and the second wire feeding wheel 8, and then transported into the third section of the three-tube 12 by the third wire feeding wheel 9 and the fourth wire feeding wheel 10. The welding wire 13 coming out of the third section of the three-tube 12 is used for subsequent welding production.

[0042] When the mediation button 115 is pressed, current flows into the coil 101, the iron core 102 is magnetized and has magnetic properties, attracting the iron block 105 to move upward, and the first connecting rod 106 moves upward accordingly. The movable block 107 rotates around the second connecting rod 109 driven by the first connecting rod 106, so that the mediation block 110 fixed on the second connecting rod 109 rotates, lifting the welding wire 13, and the welding wire 13 loses contact with the first wool wheel 5 and the second wool wheel 6 and stops moving forward.

[0043] When the reset button 16 is pressed, the current in the coil 101 is cut off, the magnetism of the coil 101 disappears, the iron block 105, the first connecting rod 106, the movable block 107, the second connecting rod 109 and the mediation block 110 are all restored to the positions before the coil 101 is energized, and the welding wire 13 continues to move forward. At this time, the buffer bolt 112 plays a buffering and supporting role to reduce the damage that may be caused when the iron core 102, the iron block 105 and the first connecting rod 106 fall.

[0044] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principle of the present invention should be included in the protection scope of the present invention.
